@c Macro definitions for commands and keys
|
||
@c =======================================
|
||
|
||
@c The behavior of the key/command macros will depend on the flag cmdnames
|
||
@c When set, commands names are shown. When clear, they are not shown.
|
||
|

@c Below we define the following macros for Org key tables:
|
||
|
||
@c orgkey{key} A key item
|
||
@c orgcmd{key,cmd} Key with command name
|
||
@c xorgcmd{key,cmd} Key with command name as @itemx
|
||
@c orgcmdnki{key,cmd} Like orgcmd, but do not index the key
|
||
@c orgcmdtkc{text,key,cmd} Like orgcmd,special text instead of key
|
||
@c orgcmdkkc{key1,key2,cmd} Two keys with one command name, use "or"
|
||
@c orgcmdkxkc{key1,key2,cmd} Two keys with one command name, but
|
||
@c different functions, so format as @itemx
|
||
@c orgcmdkskc{key1,key2,cmd} Same as orgcmdkkc, but use "or short"

@section Summary
|
||
@cindex summary
|
||
|
||
Org is a mode for keeping notes, maintaining TODO lists, and doing
|
||
project planning with a fast and effective plain-text system.
|
||
|
||
Org develops organizational tasks around NOTES files that contain
|
||
lists or information about projects as plain text. Org is
|
||
implemented on top of Outline mode, which makes it possible to keep the
|
||
content of large files well structured. Visibility cycling and
|
||
structure editing help to work with the tree. Tables are easily created
|
||
with a built-in table editor. Org supports TODO items, deadlines,
|
||
timestamps, and scheduling. It dynamically compiles entries into an
|
||
agenda that utilizes and smoothly integrates much of the Emacs calendar
|
||
and diary. Plain text URL-like links connect to websites, emails,
|
||
Usenet messages, BBDB entries, and any files related to the projects.
|
||
For printing and sharing of notes, an Org file can be exported as a
|
||
structured ASCII file, as HTML, or (TODO and agenda items only) as an
|
||
iCalendar file. It can also serve as a publishing tool for a set of
|
||
linked web pages.
|
||
|
||
As a project planning environment, Org works by adding metadata to outline
|
||
nodes. Based on this data, specific entries can be extracted in queries and
|
||
create dynamic @i{agenda views}.
|
||
|
||
Org mode contains the Org Babel environment which allows you to work with
|
||
embedded source code blocks in a file, to facilitate code evaluation,
|
||
documentation, and literate programming techniques.
|
||
|
||
Org's automatic, context-sensitive table editor with spreadsheet
|
||
capabilities can be integrated into any major mode by activating the
|
||
minor Orgtbl mode. Using a translation step, it can be used to maintain
|
||
tables in arbitrary file types, for example in @LaTeX{}. The structure
|
||
editing and list creation capabilities can be used outside Org with
|
||
the minor Orgstruct mode.
|
||
|
||
Org keeps simple things simple. When first fired up, it should
|
||
feel like a straightforward, easy to use outliner. Complexity is not
|
||
imposed, but a large amount of functionality is available when you need
|
||
it. Org is a toolbox and can be used in different ways and for different
|
||
ends, for example:
|
||
|
||
@example
|
||
@r{@bullet{} an outline extension with visibility cycling and structure editing}
|
||
@r{@bullet{} an ASCII system and table editor for taking structured notes}
|
||
@r{@bullet{} a TODO list editor}
|
||
@r{@bullet{} a full agenda and planner with deadlines and work scheduling}
|
||
@pindex GTD, Getting Things Done
|
||
@r{@bullet{} an environment in which to implement David Allen's GTD system}
|
||
@r{@bullet{} a simple hypertext system, with HTML and @LaTeX{} export}
|
||
@r{@bullet{} a publishing tool to create a set of interlinked webpages}
|
||
@r{@bullet{} an environment for literate programming}
|
||
@end example
|
||
|
||
|
||

@node Installation, Activation, Summary, Introduction
|
||
@section Installation
|
||
@cindex installation
|
||
@cindex XEmacs
|
||
|
||
@b{Important:} @i{If you are using a version of Org that is part of the Emacs
|
||
distribution or an XEmacs package, please skip this section and go directly
|
||
to @ref{Activation}. To see what version of Org (if any) is part of your
|
||
Emacs distribution, type @kbd{M-x load-library RET org} and then @kbd{M-x
|
||
org-version}.}
|
||
|
||
If you have downloaded Org from the Web, either as a distribution @file{.zip}
|
||
or @file{.tar} file, or as a Git archive, you must take the following steps
|
||
to install it: go into the unpacked Org distribution directory and edit the
|
||
top section of the file @file{Makefile}. You must set the name of the Emacs
|
||
binary (likely either @file{emacs} or @file{xemacs}), and the paths to the
|
||
directories where local Lisp and Info files are kept. If you don't have
|
||
access to the system-wide directories, you can simply run Org directly from
|
||
the distribution directory by adding the @file{lisp} subdirectory to the
|
||
Emacs load path. To do this, add the following line to @file{.emacs}:
|
||
|
||
@example
|
||
(setq load-path (cons "~/path/to/orgdir/lisp" load-path))
|
||
@end example
|
||
|
||
@noindent
|
||
If you plan to use code from the @file{contrib} subdirectory, do a similar
|
||
step for this directory:
|
||
|
||
@example
|
||
(setq load-path (cons "~/path/to/orgdir/contrib/lisp" load-path))
|
||
@end example
|
||
|
||
@noindent Now byte-compile the Lisp files with the shell command:
|
||
|
||
@example
|
||
make
|
||
@end example
|
||
|
||
@noindent If you are running Org from the distribution directory, this is
|
||
all. If you want to install Org into the system directories, use (as
|
||
administrator)
|
||
|
||
@example
|
||
make install
|
||
@end example
|
||
|
||
Installing Info files is system dependent, because of differences in the
|
||
@file{install-info} program. The following should correctly install the Info
|
||
files on most systems, please send a bug report if not@footnote{The output
|
||
from install-info (if any) is also system dependent. In particular Debian
|
||
and its derivatives use two different versions of install-info and you may
|
||
see the message:
|
||
|
||
@example
|
||
This is not dpkg install-info anymore, but GNU install-info
|
||
See the man page for ginstall-info for command line arguments
|
||
@end example
|
||
|
||
@noindent which can be safely ignored.}.
|
||
|
||
@example
|
||
make install-info
|
||
@end example
|
||
|
||
Then add the following line to @file{.emacs}. It is needed so that
|
||
Emacs can autoload functions that are located in files not immediately loaded
|
||
when Org mode starts.
|
||
@lisp
|
||
(require 'org-install)
|
||
@end lisp
|
||
|
||
Do not forget to activate Org as described in the following section.

||

|
||
|
||
To make sure files with extension @file{.org} use Org mode, add the following
|
||
line to your @file{.emacs} file.
|
||
@lisp
|
||
(add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))
|
||
@end lisp
|
||
@noindent Org mode buffers need font-lock to be turned on - this is the
|
||
default in Emacs@footnote{If you don't use font-lock globally, turn it on in
|
||
Org buffer with @code{(add-hook 'org-mode-hook 'turn-on-font-lock)}}.
|
||
|
||
The four Org commands @command{org-store-link}, @command{org-capture},
|
||
@command{org-agenda}, and @command{org-iswitchb} should be accessible through
|
||
global keys (i.e.@: anywhere in Emacs, not just in Org buffers). Here are
|
||
suggested bindings for these keys, please modify the keys to your own
|
||
liking.
|
||
@lisp
|
||
(global-set-key "\C-cl" 'org-store-link)
|
||
(global-set-key "\C-cc" 'org-capture)
|
||
(global-set-key "\C-ca" 'org-agenda)
|
||
(global-set-key "\C-cb" 'org-iswitchb)
|
||
@end lisp
|
||
|
||
@cindex Org mode, turning on
|
||
With this setup, all files with extension @samp{.org} will be put
|
||
into Org mode. As an alternative, make the first line of a file look
|
||
like this:
|
||
|
||
@example
|
||
MY PROJECTS -*- mode: org; -*-
|
||
@end example
|
||
|
||
@vindex org-insert-mode-line-in-empty-file
|
||
@noindent which will select Org mode for this buffer no matter what
|
||
the file's name is. See also the variable
|
||
@code{org-insert-mode-line-in-empty-file}.
|
||
|
||
Many commands in Org work on the region if the region is @i{active}. To make
|
||
use of this, you need to have @code{transient-mark-mode}
|
||
(@code{zmacs-regions} in XEmacs) turned on. In Emacs 23 this is the default,
|
||
in Emacs 22 you need to do this yourself with
|
||
@lisp
|
||
(transient-mark-mode 1)
|
||
@end lisp
|
||
@noindent If you do not like @code{transient-mark-mode}, you can create an
|
||
active region by using the mouse to select a region, or pressing
|
||
@kbd{C-@key{SPC}} twice before moving the cursor.

If you find problems with Org, or if you have questions, remarks, or ideas
|
||
about it, please mail to the Org mailing list @email{emacs-orgmode@@gnu.org}.
|
||
If you are not a member of the mailing list, your mail will be passed to the
|
||
list after a moderator has approved it@footnote{Please consider subscribing
|
||
to the mailing list, in order to minimize the work the mailing list
|
||
moderators have to do.}.
|
||
|
||
For bug reports, please first try to reproduce the bug with the latest
|
||
version of Org available---if you are running an outdated version, it is
|
||
quite possible that the bug has been fixed already. If the bug persists,
|
||
prepare a report and provide as much information as possible, including the
|
||
version information of Emacs (@kbd{M-x emacs-version @key{RET}}) and Org
|
||
(@kbd{M-x org-version @key{RET}}), as well as the Org related setup in
|
||
@file{.emacs}. The easiest way to do this is to use the command
|
||
@example
|
||
@kbd{M-x org-submit-bug-report}
|
||
@end example
|
||
@noindent which will put all this information into an Emacs mail buffer so
|
||
that you only need to add your description. If you re not sending the Email
|
||
from within Emacs, please copy and paste the content into your Email program.
|
||
|
||
Sometimes you might face a problem due to an error in your Emacs or Org mode
|
||
setup. Before reporting a bug, it is very helpful to start Emacs with minimal
|
||
customizations and reproduce the problem. Doing so often helps you determine
|
||
if the problem is with your customization or with Org mode itself. You can
|
||
start a typical minimal session with a command like the example below.
|
||
|
||
@example
|
||
$ emacs -Q -l /path/to/minimal-org.el
|
||
@end example
|
||
|
||
However if you are using Org mode as distributed with Emacs, a minimal setup
|
||
is not necessary. In that case it is sufficient to start Emacs as @code{emacs
|
||
-Q}. The @code{minimal-org.el} setup file can have contents as shown below.
|
||
|

If an error occurs, a backtrace can be very useful (see below on how to
|
||
create one). Often a small example file helps, along with clear information
|
||
about:
|
||
|
||
@enumerate
|
||
@item What exactly did you do?
|
||
@item What did you expect to happen?
|
||
@item What happened instead?

@subsubheading How to create a useful backtrace
|
||
|
||
@cindex backtrace of an error
|
||
If working with Org produces an error with a message you don't
|
||
understand, you may have hit a bug. The best way to report this is by
|
||
providing, in addition to what was mentioned above, a @emph{backtrace}.
|
||
This is information from the built-in debugger about where and how the
|
||
error occurred. Here is how to produce a useful backtrace:
|
||
|
||
@enumerate
|
||
@item
|
||
Reload uncompiled versions of all Org mode Lisp files. The backtrace
|
||
contains much more information if it is produced with uncompiled code.
|
||
To do this, use
|
||
@example
|
||
C-u M-x org-reload RET
|
||
@end example
|
||
@noindent
|
||
or select @code{Org -> Refresh/Reload -> Reload Org uncompiled} from the
|
||
menu.
|
||
@item
|
||
Go to the @code{Options} menu and select @code{Enter Debugger on Error}
|
||
(XEmacs has this option in the @code{Troubleshooting} sub-menu).
|
||
@item
|
||
Do whatever you have to do to hit the error. Don't forget to
|
||
document the steps you take.
|
||
@item
|
||
When you hit the error, a @file{*Backtrace*} buffer will appear on the
|
||
screen. Save this buffer to a file (for example using @kbd{C-x C-w}) and
|
||
attach it to your bug report.
|
||
@end enumerate

@node Conventions, , Feedback, Introduction
|
||
@section Typesetting conventions used in this manual
|
||
|
||
Org uses three types of keywords: TODO keywords, tags, and property
|
||
names. In this manual we use the following conventions:
|
||
|
||
@table @code
|
||
@item TODO
|
||
@itemx WAITING
|
||
TODO keywords are written with all capitals, even if they are
|
||
user-defined.
|
||
@item boss
|
||
@itemx ARCHIVE
|
||
User-defined tags are written in lowercase; built-in tags with special
|
||
meaning are written with all capitals.
|
||
@item Release
|
||
@itemx PRIORITY
|
||
User-defined properties are capitalized; built-in properties with
|
||
special meaning are written with all capitals.
|
||
@end table
|
||
|
||
The manual lists both the keys and the corresponding commands for accessing
|
||
functionality. Org mode often uses the same key for different functions,
|
||
depending on context. The command that is bound to such keys has a generic
|
||
name, like @code{org-metaright}. In the manual we will, wherever possible,
|
||
give the function that is internally called by the generic command. For
|
||
example, in the chapter on document structure, @kbd{M-@key{right}} will be
|
||
listed to call @code{org-do-demote}, while in the chapter on tables, it will
|
||
be listed to call org-table-move-column-right.
|
||
|
||
If you prefer, you can compile the manual without the command names by
|
||
unsetting the flag @code{cmdnames} in @file{org.texi}.

@cindex outlines

@cindex Outline mode
|
||
|
||
Org is implemented on top of Outline mode. Outlines allow a
|
||
document to be organized in a hierarchical structure, which (at least
|
||
for me) is the best representation of notes and thoughts. An overview
|
||
of this structure is achieved by folding (hiding) large parts of the
|
||
document to show only the general document structure and the parts
|
||
currently being worked on. Org greatly simplifies the use of
|
||
outlines by compressing the entire show/hide functionality into a single
|
||
command, @command{org-cycle}, which is bound to the @key{TAB} key.

||

|
||
@vindex org-special-ctrl-k
|
||
@vindex org-ctrl-k-protect-subtree
|
||
|
||
Headlines define the structure of an outline tree. The headlines in Org
|
||
start with one or more stars, on the left margin@footnote{See the variables
|
||
@code{org-special-ctrl-a/e}, @code{org-special-ctrl-k}, and
|
||
@code{org-ctrl-k-protect-subtree} to configure special behavior of @kbd{C-a},
|
||
@kbd{C-e}, and @kbd{C-k} in headlines.}. For example:
|
||
|
||
@example
|
||
* Top level headline
|
||
** Second level
|
||
*** 3rd level
|
||
some text
|
||
*** 3rd level
|
||
more text
|
||
|
||
* Another top level headline
|
||
@end example
|
||
|
||
@noindent Some people find the many stars too noisy and would prefer an
|
||
outline that has whitespace followed by a single star as headline
|
||
starters. @ref{Clean view}, describes a setup to realize this.
|
||
|
||
@vindex org-cycle-separator-lines
|
||
An empty line after the end of a subtree is considered part of it and
|
||
will be hidden when the subtree is folded. However, if you leave at
|
||
least two empty lines, one empty line will remain visible after folding
|
||
the subtree, in order to structure the collapsed view. See the
|
||
variable @code{org-cycle-separator-lines} to modify this behavior.

The cursor must be on a headline for this to work@footnote{see, however,
|
||
the option @code{org-cycle-emulate-tab}.}. When the cursor is at the
|
||
beginning of the buffer and the first line is not a headline, then
|
||
@key{TAB} actually runs global cycling (see below)@footnote{see the
|
||
option @code{org-cycle-global-at-bob}.}. Also when called with a prefix
|
||
argument (@kbd{C-u @key{TAB}}), global cycling is invoked.

When @kbd{S-@key{TAB}} is called with a numeric prefix argument N, the

@orgcmd{C-u C-u C-u @key{TAB},show-all}
|
||
Show all, including drawers.
|
||
@orgcmd{C-c C-r,org-reveal}
|
||
Reveal context around point, showing the current entry, the following heading
|
||
and the hierarchy above. Useful for working near a location that has been
|
||
exposed by a sparse tree command (@pxref{Sparse trees}) or an agenda command
|
||
(@pxref{Agenda commands}). With a prefix argument show, on each
|
||
level, all sibling headings. With a double prefix argument, also show the
|
||
entire subtree of the parent.
|
||
@orgcmd{C-c C-k,show-branches}
|
||
Expose all the headings of the subtree, CONTENT view for just one subtree.
|
||
@orgcmd{C-c C-x b,org-tree-to-indirect-buffer}
|
||
Show the current subtree in an indirect buffer@footnote{The indirect

(@pxref{Indirect Buffers,,,emacs,GNU Emacs Manual})
|
||
@end ifinfo
|

@ifnotinfo
|

(see the Emacs manual for more information about indirect buffers)
|
||
@end ifnotinfo
|
||
will contain the entire buffer, but will be narrowed to the current
|
||
tree. Editing the indirect buffer will also change the original buffer,
|
||
but without affecting visibility in that buffer.}. With a numeric
|
||
prefix argument N, go up to level N and then take that tree. If N is
|
||
negative then go up that many levels. With a @kbd{C-u} prefix, do not remove
|
||
the previously used indirect buffer.
|

@orgcmd{M-@key{RET},org-insert-heading}
|

@vindex org-M-RET-may-split-line
|
||
Insert new heading with same level as current. If the cursor is in a plain
|
||
list item, a new item is created (@pxref{Plain lists}). To force creation of
|
||
a new headline, use a prefix argument. When this command is used in the
|
||
middle of a line, the line is split and the rest of the line becomes the new
|
||
headline@footnote{If you do not want the line to be split, customize the
|
||
variable @code{org-M-RET-may-split-line}.}. If the command is used at the
|
||
beginning of a headline, the new headline is created before the current line.
|
||
If at the beginning of any other line, the content of that line is made the
|
||
new heading. If the command is used at the end of a folded subtree (i.e.@:
|
||
behind the ellipses at the end of a headline), then a headline like the
|
||
current one will be inserted after the end of the subtree.
|
||
@orgcmd{C-@key{RET},org-insert-heading-respect-content}
|
||
Just like @kbd{M-@key{RET}}, except when adding a new heading below the
|
||
current heading, the new heading is placed after the body instead of before
|
||
it. This command works from anywhere in the entry.
|
||
@orgcmd{M-S-@key{RET},org-insert-todo-heading}
|
||
@vindex org-treat-insert-todo-heading-as-state-change
|
||
Insert new TODO entry with same level as current heading. See also the
|
||
variable @code{org-treat-insert-todo-heading-as-state-change}.
|
||
@orgcmd{C-S-@key{RET},org-insert-todo-heading-respect-content}
|
||
Insert new TODO entry with same level as current heading. Like
|
||
@kbd{C-@key{RET}}, the new headline will be inserted after the current
|
||
subtree.
|
||
@orgcmd{@key{TAB},org-cycle}
|
||
In a new entry with no text yet, the first @key{TAB} demotes the entry to
|
||
become a child of the previous one. The next @key{TAB} makes it a parent,
|
||
and so on, all the way to top level. Yet another @key{TAB}, and you are back
|
||
to the initial level.
|
||
@orgcmd{M-@key{left},org-do-promote}
|
||
Promote current heading by one level.
|
||
@orgcmd{M-@key{right},org-do-demote}
|
||
Demote current heading by one level.
|
||
@orgcmd{M-S-@key{left},org-promote-subtree}
|
||
Promote the current subtree by one level.
|
||
@orgcmd{M-S-@key{right},org-demote-subtree}
|
||
Demote the current subtree by one level.
|
||
@orgcmd{M-S-@key{up},org-move-subtree-up}
|
||
Move subtree up (swap with previous subtree of same
|
||
level).
|
||
@orgcmd{M-S-@key{down},org-move-subtree-down}
|
||
Move subtree down (swap with next subtree of same level).
|
||
@orgcmd{C-c C-x C-w,org-cut-subtree}
|
||
Kill subtree, i.e.@: remove it from buffer but save in kill ring.
|
||
With a numeric prefix argument N, kill N sequential subtrees.
|
||
@orgcmd{C-c C-x M-w,org-copy-subtree}
|
||
Copy subtree to kill ring. With a numeric prefix argument N, copy the N
|
||
sequential subtrees.
|
||
@orgcmd{C-c C-x C-y,org-paste-subtree}
|
||
Yank subtree from kill ring. This does modify the level of the subtree to
|
||
make sure the tree fits in nicely at the yank position. The yank level can
|
||
also be specified with a numeric prefix argument, or by yanking after a
|
||
headline marker like @samp{****}.
|
||
@orgcmd{C-y,org-yank}
|
||
@vindex org-yank-adjusted-subtrees
|
||
@vindex org-yank-folded-subtrees
|
||
Depending on the variables @code{org-yank-adjusted-subtrees} and
|
||
@code{org-yank-folded-subtrees}, Org's internal @code{yank} command will
|
||
paste subtrees folded and in a clever way, using the same command as @kbd{C-c
|
||
C-x C-y}. With the default settings, no level adjustment will take place,
|
||
but the yanked tree will be folded unless doing so would swallow text
|
||
previously visible. Any prefix argument to this command will force a normal
|
||
@code{yank} to be executed, with the prefix passed along. A good way to
|
||
force a normal yank is @kbd{C-u C-y}. If you use @code{yank-pop} after a
|
||
yank, it will yank previous kill items plainly, without adjustment and
|
||
folding.
|
||
@orgcmd{C-c C-x c,org-clone-subtree-with-time-shift}
|
||
Clone a subtree by making a number of sibling copies of it. You will be
|
||
prompted for the number of copies to make, and you can also specify if any
|
||
timestamps in the entry should be shifted. This can be useful, for example,
|
||
to create a number of tasks related to a series of lectures to prepare. For
|
||
more details, see the docstring of the command
|
||
@code{org-clone-subtree-with-time-shift}.
|
||
@orgcmd{C-c C-w,org-refile}
|
||
Refile entry or region to a different location. @xref{Refiling notes}.
|
||
@orgcmd{C-c ^,org-sort-entries-or-items}
|
||
Sort same-level entries. When there is an active region, all entries in the
|
||
region will be sorted. Otherwise the children of the current headline are
|
||
sorted. The command prompts for the sorting method, which can be
|
||
alphabetically, numerically, by time (first timestamp with active preferred,
|
||
creation time, scheduled time, deadline time), by priority, by TODO keyword
|
||
(in the sequence the keywords have been defined in the setup) or by the value
|
||
of a property. Reverse sorting is possible as well. You can also supply
|
||
your own function to extract the sorting key. With a @kbd{C-u} prefix,
|
||
sorting will be case-sensitive.
|
||
@orgcmd{C-x n s,org-narrow-to-subtree}
|
||
Narrow buffer to current subtree.
|
||
@orgcmd{C-x n b,org-narrow-to-block}
|
||
Narrow buffer to current block.
|
||
@orgcmd{C-x n w,widen}
|
||
Widen buffer to remove narrowing.
|
||
@orgcmd{C-c *,org-toggle-heading}
|
||
Turn a normal line or plain list item into a headline (so that it becomes a
|
||
subheading at its location). Also turn a headline into a normal line by
|
||
removing the stars. If there is an active region, turn all lines in the
|
||
region into headlines. If the first line in the region was an item, turn
|
||
only the item lines into headlines. Finally, if the first line is a
|
||
headline, remove the stars from all headlines in the region.

@vindex org-show-siblings
|

@vindex org-show-entry-below
|
||
An important feature of Org mode is the ability to construct @emph{sparse
|
||
trees} for selected information in an outline tree, so that the entire
|
||
document is folded as much as possible, but the selected information is made
|
||
visible along with the headline structure above it@footnote{See also the
|
||
variables @code{org-show-hierarchy-above}, @code{org-show-following-heading},
|
||
@code{org-show-siblings}, and @code{org-show-entry-below} for detailed
|
||
control on how much context is shown around each match.}. Just try it out
|
||
and you will see immediately how it works.
|
||
|
||
Org mode contains several commands creating such trees, all these
|
||
commands can be accessed through a dispatcher:
|
||
|
||
@table @asis
|
||
@orgcmd{C-c /,org-sparse-tree}
|
||
This prompts for an extra key to select a sparse-tree creating command.
|
||
@orgcmd{C-c / r,org-occur}
|
||
@vindex org-remove-highlights-with-change
|
||
Prompts for a regexp and shows a sparse tree with all matches. If
|
||
the match is in a headline, the headline is made visible. If the match is in
|
||
the body of an entry, headline and body are made visible. In order to
|
||
provide minimal context, also the full hierarchy of headlines above the match
|
||
is shown, as well as the headline following the match. Each match is also
|
||
highlighted; the highlights disappear when the buffer is changed by an
|
||
editing command@footnote{This depends on the option
|
||
@code{org-remove-highlights-with-change}}, or by pressing @kbd{C-c C-c}.
|
||
When called with a @kbd{C-u} prefix argument, previous highlights are kept,
|
||
so several calls to this command can be stacked.
|
||
@orgcmdkkc{M-g n,M-g M-n,next-error}
|
||
Jump to the next sparse tree match in this buffer.
|
||
@orgcmdkkc{M-g p,M-g M-p,previous-error}
|
||
Jump to the previous sparse tree match in this buffer.
|
||
@end table
|
||
|
||
|
||
@noindent
|
||
@vindex org-agenda-custom-commands
|
||
For frequently used sparse trees of specific search strings, you can
|
||
use the variable @code{org-agenda-custom-commands} to define fast
|
||
keyboard access to specific sparse trees. These commands will then be
|
||
accessible through the agenda dispatcher (@pxref{Agenda dispatcher}).
|
||
For example:
|
||
|
||
@lisp
|
||
(setq org-agenda-custom-commands
|
||
'(("f" occur-tree "FIXME")))
|
||
@end lisp
|
||
|
||
@noindent will define the key @kbd{C-c a f} as a shortcut for creating
|
||
a sparse tree matching the string @samp{FIXME}.
|
||
|
||
The other sparse tree commands select headings based on TODO keywords,
|
||
tags, or properties and will be discussed later in this manual.
|
||
|
||
@kindex C-c C-e v
|
||
@cindex printing sparse trees
|
||
@cindex visible text, printing
|
||
To print a sparse tree, you can use the Emacs command
|
||
@code{ps-print-buffer-with-faces} which does not print invisible parts
|
||
of the document @footnote{This does not work under XEmacs, because
|
||
XEmacs uses selective display for outlining, not text properties.}.
|
||
Or you can use the command @kbd{C-c C-e v} to export only the visible
|
||
part of the document and print the resulting file.

@cindex ordered lists
|
||
|
||
Within an entry of the outline tree, hand-formatted lists can provide
|
||
additional structure. They also provide a way to create lists of checkboxes
|
||
(@pxref{Checkboxes}). Org supports editing such lists, and every exporter
|
||
(@pxref{Exporting}) can parse and format them.
|
||
|
||
Org knows ordered lists, unordered lists, and description lists.
|
||
@itemize @bullet
|
||
@item
|
||
@emph{Unordered} list items start with @samp{-}, @samp{+}, or
|
||
@samp{*}@footnote{When using @samp{*} as a bullet, lines must be indented or
|
||
they will be seen as top-level headlines. Also, when you are hiding leading
|
||
stars to get a clean outline view, plain list items starting with a star may
|
||
be hard to distinguish from true headlines. In short: even though @samp{*}
|
||
is supported, it may be better to not use it for plain list items.} as
|
||
bullets.
|
||
@item
|
||
@vindex org-plain-list-ordered-item-terminator
|
||
@vindex org-alphabetical-lists
|
||
@emph{Ordered} list items start with a numeral followed by either a period or
|
||
a right parenthesis@footnote{You can filter out any of them by configuring
|
||
@code{org-plain-list-ordered-item-terminator}.}, such as @samp{1.} or
|
||
@samp{1)}@footnote{You can also get @samp{a.}, @samp{A.}, @samp{a)} and
|
||
@samp{A)} by configuring @code{org-alphabetical-lists}. To minimize
|
||
confusion with normal text, those are limited to one character only. Beyond
|
||
that limit, bullets will automatically fallback to numbers.}. If you want a
|
||
list to start with a different value (e.g.@: 20), start the text of the item
|
||
with @code{[@@20]}@footnote{If there's a checkbox in the item, the cookie
|
||
must be put @emph{before} the checkbox. If you have activated alphabetical
|
||
lists, you can also use counters like @code{[@@b]}.}. Those constructs can
|
||
be used in any item of the list in order to enforce a particular numbering.
|
||
@item
|
||
@emph{Description} list items are unordered list items, and contain the
|
||
separator @samp{ :: } to distinguish the description @emph{term} from the
|
||
description.
|
||
@end itemize
|
||
|
||
Items belonging to the same list must have the same indentation on the first
|
||
line. In particular, if an ordered list reaches number @samp{10.}, then the
|
||
2--digit numbers must be written left-aligned with the other numbers in the
|
||
list. An item ends before the next line that is less or equally indented
|
||
than its bullet/number.
|
||
|
||
@vindex org-empty-line-terminates-plain-lists
|
||
A list ends whenever every item has ended, which means before any line less
|
||
or equally indented than items at top level. It also ends before two blank
|
||
lines@footnote{See also @code{org-empty-line-terminates-plain-lists}.}. In
|
||
that case, all items are closed. Here is an example:
|
||
|
||
@example
|
||
@group
|
||
** Lord of the Rings
|
||
My favorite scenes are (in this order)
|
||
1. The attack of the Rohirrim
|
||
2. Eowyn's fight with the witch king
|
||
+ this was already my favorite scene in the book
|
||
+ I really like Miranda Otto.
|
||
3. Peter Jackson being shot by Legolas
|
||
- on DVD only
|
||
He makes a really funny face when it happens.
|
||
But in the end, no individual scenes matter but the film as a whole.
|
||
Important actors in this film are:
|
||
- @b{Elijah Wood} :: He plays Frodo
|
||
- @b{Sean Austin} :: He plays Sam, Frodo's friend. I still remember
|
||
him very well from his role as Mikey Walsh in @i{The Goonies}.
|
||
@end group
|
||
@end example
|
||
|
||
Org supports these lists by tuning filling and wrapping commands to deal with
|
||
them correctly@footnote{Org only changes the filling settings for Emacs. For
|
||
XEmacs, you should use Kyle E. Jones' @file{filladapt.el}. To turn this on,
|
||
put into @file{.emacs}: @code{(require 'filladapt)}}, and by exporting them
|
||
properly (@pxref{Exporting}). Since indentation is what governs the
|
||
structure of these lists, many structural constructs like @code{#+BEGIN_...}
|
||
blocks can be indented to signal that they belong to a particular item.
|
||
|
||
@vindex org-list-demote-modify-bullet
|
||
@vindex org-list-indent-offset
|
||
If you find that using a different bullet for a sub-list (than that used for
|
||
the current list-level) improves readability, customize the variable
|
||
@code{org-list-demote-modify-bullet}. To get a greater difference of
|
||
indentation between items and theirs sub-items, customize
|
||
@code{org-list-indent-offset}.
|
||
|
||
@vindex org-list-automatic-rules
|
||
The following commands act on items when the cursor is in the first line of
|
||
an item (the line with the bullet or number). Some of them imply the
|
||
application of automatic rules to keep list structure intact. If some of
|
||
these actions get in your way, configure @code{org-list-automatic-rules}
|
||
to disable them individually.
|
||
|
||
@table @asis
|
||
@orgcmd{@key{TAB},org-cycle}
|
||
@cindex cycling, in plain lists
|
||
@vindex org-cycle-include-plain-lists
|
||
Items can be folded just like headline levels. Normally this works only if
|
||
the cursor is on a plain list item. For more details, see the variable
|
||
@code{org-cycle-include-plain-lists}. If this variable is set to
|
||
@code{integrate}, plain list items will be treated like low-level
|
||
headlines. The level of an item is then given by the indentation of the
|
||
bullet/number. Items are always subordinate to real headlines, however; the
|
||
hierarchies remain completely separated. In a new item with no text yet, the
|
||
first @key{TAB} demotes the item to become a child of the previous
|
||
one. Subsequent @key{TAB}s move the item to meaningful levels in the list
|
||
and eventually get it back to its initial position.
|
||
@orgcmd{M-@key{RET},org-insert-heading}
|
||
@vindex org-M-RET-may-split-line
|
||
@vindex org-list-automatic-rules
|
||
Insert new item at current level. With a prefix argument, force a new
|
||
heading (@pxref{Structure editing}). If this command is used in the middle
|
||
of an item, that item is @emph{split} in two, and the second part becomes the
|
||
new item@footnote{If you do not want the item to be split, customize the
|
||
variable @code{org-M-RET-may-split-line}.}. If this command is executed
|
||
@emph{before item's body}, the new item is created @emph{before} the current
|
||
one.
|

@end table
|
||
|
||
@table @kbd
|

@kindex M-S-@key{RET}

@itemx S-down
|
||
@cindex shift-selection-mode
|
||
@vindex org-support-shift-select
|
||
@vindex org-list-use-circular-motion
|
||
Jump to the previous/next item in the current list@footnote{If you want to
|
||
cycle around items that way, you may customize
|
||
@code{org-list-use-circular-motion}.}, but only if
|
||
@code{org-support-shift-select} is off. If not, you can still use paragraph
|
||
jumping commands like @kbd{C-@key{up}} and @kbd{C-@key{down}} to quite
|
||
similar effect.
|
||
@kindex M-@key{up}
|
||
@kindex M-@key{down}
|
||
@item M-up
|
||
@itemx M-down
|
||
Move the item including subitems up/down@footnote{See
|
||
@code{org-liste-use-circular-motion} for a cyclic behavior.} (swap with
|
||
previous/next item of same indentation). If the list is ordered, renumbering
|
||
is automatic.
|
||
@kindex M-@key{left}
|
||
@kindex M-@key{right}
|
||
@item M-left
|
||
@itemx M-right
|
||
Decrease/increase the indentation of an item, leaving children alone.
|
||
@kindex M-S-@key{left}
|
||
@kindex M-S-@key{right}
|
||
@item M-S-left
|
||
@itemx M-S-right
|
||
Decrease/increase the indentation of the item, including subitems.
|
||
Initially, the item tree is selected based on current indentation. When
|
||
these commands are executed several times in direct succession, the initially
|
||
selected region is used, even if the new indentation would imply a different
|
||
hierarchy. To use the new hierarchy, break the command chain with a cursor
|
||
motion or so.
|
||
|
||
As a special case, using this command on the very first item of a list will
|
||
move the whole list. This behavior can be disabled by configuring
|
||
@code{org-list-automatic-rules}. The global indentation of a list has no
|
||
influence on the text @emph{after} the list.
|
||
@kindex C-c C-c
|
||
@item C-c C-c
|
||
If there is a checkbox (@pxref{Checkboxes}) in the item line, toggle the
|
||
state of the checkbox. In any case, verify bullets and indentation
|
||
consistency in the whole list.
|
||
@kindex C-c -
|
||
@vindex org-plain-list-ordered-item-terminator
|
||
@vindex org-list-automatic-rules
|
||
@item C-c -
|
||
Cycle the entire list level through the different itemize/enumerate bullets
|
||
(@samp{-}, @samp{+}, @samp{*}, @samp{1.}, @samp{1)}) or a subset of them,
|
||
depending on @code{org-plain-list-ordered-item-terminator}, the type of list,
|
||
and its position@footnote{See @code{bullet} rule in
|
||
@code{org-list-automatic-rules} for more information.}. With a numeric
|
||
prefix argument N, select the Nth bullet from this list. If there is an
|
||
active region when calling this, selected text will be changed into an item.
|
||
With a prefix argument, all lines will be converted to list items. If the
|
||
first line already was a list item, any item marker will be removed from the
|
||
list. Finally, even without an active region, a normal line will be
|
||
converted into a list item.
|
||
@kindex C-c *
|
||
@item C-c *
|
||
Turn a plain list item into a headline (so that it becomes a subheading at
|
||
its location). @xref{Structure editing}, for a detailed explanation.
|
||
@kindex C-c C-*
|
||
@item C-c C-*
|
||
Turn the whole plain list into a subtree of the current heading. Checkboxes
|
||
(@pxref{Checkboxes}) will become TODO (resp. DONE) keywords when unchecked
|
||
(resp. checked).
|
||
@kindex S-@key{left}
|
||
@kindex S-@key{right}
|
||
@item S-left/right
|
||
@vindex org-support-shift-select
|
||
This command also cycles bullet styles when the cursor in on the bullet or
|
||
anywhere in an item line, details depending on
|
||
@code{org-support-shift-select}.
|
||
@kindex C-c ^
|
||
@item C-c ^
|
||
Sort the plain list. You will be prompted for the sorting method:
|
||
numerically, alphabetically, by time, or by custom function.

Drawers need to be configured with the variable

Visibility cycling (@pxref{Visibility cycling}) on the headline will hide and

@cindex footnotes
|
||
|
||
Org mode supports the creation of footnotes. In contrast to the
|
||
@file{footnote.el} package, Org mode's footnotes are designed for work on a
|
||
larger document, not only for one-off documents like emails. The basic
|
||
syntax is similar to the one used by @file{footnote.el}, i.e.@: a footnote is
|
||
defined in a paragraph that is started by a footnote marker in square
|
||
brackets in column 0, no indentation allowed. If you need a paragraph break
|
||
inside a footnote, use the @LaTeX{} idiom @samp{\par}. The footnote reference
|
||
is simply the marker in square brackets, inside text. For example:
|
||
|
||
@example
|
||
The Org homepage[fn:1] now looks a lot better than it used to.
|
||
...
|
||
[fn:1] The link is: http://orgmode.org
|
||
@end example
|
||
|
||
Org mode extends the number-based syntax to @emph{named} footnotes and
|
||
optional inline definition. Using plain numbers as markers (as
|
||
@file{footnote.el} does) is supported for backward compatibility, but not
|
||
encouraged because of possible conflicts with @LaTeX{} snippets (@pxref{Embedded
|
||
@LaTeX{}}). Here are the valid references:
|
||
|
||
@table @code
|
||
@item [1]
|
||
A plain numeric footnote marker. Compatible with @file{footnote.el}, but not
|
||
recommended because something like @samp{[1]} could easily be part of a code
|
||
snippet.
|
||
@item [fn:name]
|
||
A named footnote reference, where @code{name} is a unique label word, or, for
|
||
simplicity of automatic creation, a number.
|
||
@item [fn:: This is the inline definition of this footnote]
|
||
A @LaTeX{}-like anonymous footnote where the definition is given directly at the
|
||
reference point.
|
||
@item [fn:name: a definition]
|
||
An inline definition of a footnote, which also specifies a name for the note.
|
||
Since Org allows multiple references to the same note, you can then use
|
||
@code{[fn:name]} to create additional references.
|
||
@end table
|
||
|
||
@vindex org-footnote-auto-label
|
||
Footnote labels can be created automatically, or you can create names yourself.
|
||
This is handled by the variable @code{org-footnote-auto-label} and its
|
||
corresponding @code{#+STARTUP} keywords. See the docstring of that variable
|
||
for details.
|
||
|
||
@noindent The following command handles footnotes:
|
||
|
||
@table @kbd
|
||
@kindex C-c C-x f
|
||
@item C-c C-x f
|
||
The footnote action command.
|
||
|
||
When the cursor is on a footnote reference, jump to the definition. When it
|
||
is at a definition, jump to the (first) reference.
|
||
|
||
@vindex org-footnote-define-inline
|
||
@vindex org-footnote-section
|
||
@vindex org-footnote-auto-adjust
|
||
Otherwise, create a new footnote. Depending on the variable
|
||
@code{org-footnote-define-inline}@footnote{The corresponding in-buffer
|
||
setting is: @code{#+STARTUP: fninline} or @code{#+STARTUP: nofninline}}, the
|
||
definition will be placed right into the text as part of the reference, or
|
||
separately into the location determined by the variable
|
||
@code{org-footnote-section}.
|
||
|
||
When this command is called with a prefix argument, a menu of additional
|
||
options is offered:
|
||
@example
|
||
s @r{Sort the footnote definitions by reference sequence. During editing,}
|
||
@r{Org makes no effort to sort footnote definitions into a particular}
|
||
@r{sequence. If you want them sorted, use this command, which will}
|
||
@r{also move entries according to @code{org-footnote-section}. Automatic}
|
||
@r{sorting after each insertion/deletion can be configured using the}
|
||
@r{variable @code{org-footnote-auto-adjust}.}
|
||
r @r{Renumber the simple @code{fn:N} footnotes. Automatic renumbering}
|
||
@r{after each insertion/deletion can be configured using the variable}
|
||
@r{@code{org-footnote-auto-adjust}.}
|
||
S @r{Short for first @code{r}, then @code{s} action.}
|
||
n @r{Normalize the footnotes by collecting all definitions (including}
|
||
@r{inline definitions) into a special section, and then numbering them}
|
||
@r{in sequence. The references will then also be numbers. This is}
|
||
@r{meant to be the final step before finishing a document (e.g.@: sending}
|
||
@r{off an email). The exporters do this automatically, and so could}
|
||
@r{something like @code{message-send-hook}.}
|
||
d @r{Delete the footnote at point, and all definitions of and references}
|
||
@r{to it.}
|
||
@end example
|
||
Depending on the variable @code{org-footnote-auto-adjust}@footnote{the
|
||
corresponding in-buffer options are @code{fnadjust} and @code{nofnadjust}.},
|

renumbering and sorting footnotes can be automatic after each insertion or

|

|

If you like the intuitive way the Org mode structure editing and list
|
||
formatting works, you might want to use these commands in other modes like
|
||
Text mode or Mail mode as well. The minor mode @code{orgstruct-mode} makes
|
||
this possible. Toggle the mode with @kbd{M-x orgstruct-mode}, or
|
||
turn it on by default, for example in Message mode, with one of:
|
||
|
||
@lisp
|
||
(add-hook 'message-mode-hook 'turn-on-orgstruct)
|
||
(add-hook 'message-mode-hook 'turn-on-orgstruct++)
|
||
@end lisp
|
||
|
||
When this mode is active and the cursor is on a line that looks to Org like a
|
||
headline or the first line of a list item, most structure editing commands
|
||
will work, even if the same keys normally have different functionality in the
|
||
major mode you are using. If the cursor is not in one of those special
|
||
lines, Orgstruct mode lurks silently in the shadows. When you use
|
||
@code{orgstruct++-mode}, Org will also export indentation and autofill
|
||
settings into that mode, and detect item context after the first line of an
|
||
item.

@cindex table editor, built-in
|

|

Org makes it easy to format tables in plain ASCII. Any line with @samp{|} as
|
||
the first non-whitespace character is considered part of a table. @samp{|}
|
||
is also the column separator@footnote{To insert a vertical bar into a table
|
||
field, use @code{\vert} or, inside a word @code{abc\vert@{@}def}.}. A table
|
||
might look like this:
|
||
|
||
@example
|
||
| Name | Phone | Age |
|
||
|-------+-------+-----|
|
||
| Peter | 1234 | 17 |
|
||
| Anna | 4321 | 25 |
|
||
@end example
|
||
|
||
A table is re-aligned automatically each time you press @key{TAB} or
|
||
@key{RET} or @kbd{C-c C-c} inside the table. @key{TAB} also moves to
|
||
the next field (@key{RET} to the next row) and creates new table rows
|
||
at the end of the table or before horizontal lines. The indentation
|
||
of the table is set by the first line. Any line starting with
|
||
@samp{|-} is considered as a horizontal separator line and will be
|
||
expanded on the next re-align to span the whole table width. So, to
|
||
create the above table, you would only type
|
||
|
||
@example
|
||
|Name|Phone|Age|
|
||
|-
|
||
@end example
|
||
|
||
@noindent and then press @key{TAB} to align the table and start filling in
|
||
fields. Even faster would be to type @code{|Name|Phone|Age} followed by
|
||
@kbd{C-c @key{RET}}.
|
||
|
||
@vindex org-enable-table-editor
|
||
@vindex org-table-auto-blank-field
|
||
When typing text into a field, Org treats @key{DEL},
|
||
@key{Backspace}, and all character keys in a special way, so that
|
||
inserting and deleting avoids shifting other fields. Also, when
|
||
typing @emph{immediately after the cursor was moved into a new field
|
||
with @kbd{@key{TAB}}, @kbd{S-@key{TAB}} or @kbd{@key{RET}}}, the
|
||
field is automatically made blank. If this behavior is too
|
||
unpredictable for you, configure the variables
|
||
@code{org-enable-table-editor} and @code{org-table-auto-blank-field}.
|
||
|
||
@table @kbd
|
||
@tsubheading{Creation and conversion}
|
||
@orgcmd{C-c |,org-table-create-or-convert-from-region}
|
||
Convert the active region to table. If every line contains at least one
|
||
TAB character, the function assumes that the material is tab separated.
|
||
If every line contains a comma, comma-separated values (CSV) are assumed.
|
||
If not, lines are split at whitespace into fields. You can use a prefix
|
||
argument to force a specific separator: @kbd{C-u} forces CSV, @kbd{C-u
|
||
C-u} forces TAB, and a numeric argument N indicates that at least N
|
||
consecutive spaces, or alternatively a TAB will be the separator.
|
||
@*
|
||
If there is no active region, this command creates an empty Org
|
||
table. But it is easier just to start typing, like
|
||
@kbd{|Name|Phone|Age @key{RET} |- @key{TAB}}.

Re-align the table and move down to next row. Creates a new row if

necessary. At the beginning or end of a line, @key{RET} still does
|
||
NEWLINE, so it can be used to split a table.

||
below that line.
|
||
@c
|
||
@orgcmd{C-c ^,org-table-sort-lines}
|
||
Sort the table lines in the region. The position of point indicates the
|
||
column to be used for sorting, and the range of lines is the range
|
||
between the nearest horizontal separator lines, or the entire table. If
|
||
point is before the first column, you will be prompted for the sorting
|
||
column. If there is an active region, the mark specifies the first line
|
||
and the sorting column, while point should be in the last line to be
|
||
included into the sorting. The command prompts for the sorting type
|
||
(alphabetically, numerically, or by time). When called with a prefix
|
||
argument, alphabetic sorting will be case-sensitive.
|
||
|
||
@tsubheading{Regions}
|
||
@orgcmd{C-c C-x M-w,org-table-copy-region}
|
||
Copy a rectangular region from a table to a special clipboard. Point and
|
||
mark determine edge fields of the rectangle. If there is no active region,
|
||
copy just the current field. The process ignores horizontal separator lines.
|
||
@c
|
||
@orgcmd{C-c C-x C-w,org-table-cut-region}
|
||
Copy a rectangular region from a table to a special clipboard, and
|
||
blank all fields in the rectangle. So this is the ``cut'' operation.
|
||
@c
|
||
@orgcmd{C-c C-x C-y,org-table-paste-rectangle}
|
||
Paste a rectangular region into a table.
|
||
The upper left corner ends up in the current field. All involved fields
|
||
will be overwritten. If the rectangle does not fit into the present table,
|
||
the table is enlarged as needed. The process ignores horizontal separator
|
||
lines.
|
||
@c
|
||
@orgcmd{M-@key{RET},org-table-wrap-region}
|
||
Split the current field at the cursor position and move the rest to the line
|
||
below. If there is an active region, and both point and mark are in the same
|
||
column, the text in the column is wrapped to minimum width for the given
|
||
number of lines. A numeric prefix argument may be used to change the number
|
||
of desired lines. If there is no region, but you specify a prefix argument,
|
||
the current field is made blank, and the content is appended to the field
|
||
above.

be inserted with @kbd{C-y}.
|

@c

@orgcmd{S-@key{RET},org-table-copy-down}

@vindex org-table-copy-increment
|
||
When current field is empty, copy from first non-empty field above. When not
|
||
empty, copy current field down to next row and move cursor along with it.
|
||
Depending on the variable @code{org-table-copy-increment}, integer field
|
||
values will be incremented during copy. Integers that are too large will not
|
||
be incremented. Also, a @code{0} prefix argument temporarily disables the
|
||
increment. This key is also used by shift-selection and related modes
|
||
(@pxref{Conflicts}).
|
||
|
||
@tsubheading{Miscellaneous}
|
||
@orgcmd{C-c `,org-table-edit-field}
|
||
Edit the current field in a separate window. This is useful for fields that
|
||
are not fully visible (@pxref{Column width and alignment}). When called with
|
||
a @kbd{C-u} prefix, just make the full field visible, so that it can be
|
||
edited in place. When called with two @kbd{C-u} prefixes, make the editor
|
||
window follow the cursor through the table and always show the current
|
||
field. The follow mode exits automatically when the cursor leaves the table,
|
||
or when you repeat this command with @kbd{C-u C-u C-c `}.
|
||
@c
|
||
@item M-x org-table-import
|
||
Import a file as a table. The table should be TAB or whitespace
|
||
separated. Use, for example, to import a spreadsheet table or data
|
||
from a database, because these programs generally can write
|
||
TAB-separated text files. This command works by inserting the file into
|
||
the buffer and then converting the region to a table. Any prefix
|
||
argument is passed on to the converter, which uses it to determine the
|
||
separator.
|
||
@orgcmd{C-c |,org-table-create-or-convert-from-region}
|
||
Tables can also be imported by pasting tabular text into the Org
|
||
buffer, selecting the pasted text with @kbd{C-x C-x} and then using the
|
||
@kbd{C-c |} command (see above under @i{Creation and conversion}).
|
||
@c
|
||
@item M-x org-table-export
|
||
@findex org-table-export
|
||
@vindex org-table-export-default-format
|
||
Export the table, by default as a TAB-separated file. Use for data
|
||
exchange with, for example, spreadsheet or database programs. The format
|
||
used to export the file can be configured in the variable
|
||
@code{org-table-export-default-format}. You may also use properties
|
||
@code{TABLE_EXPORT_FILE} and @code{TABLE_EXPORT_FORMAT} to specify the file
|
||
name and the format for table export in a subtree. Org supports quite
|
||
general formats for exported tables. The exporter format is the same as the
|
||
format used by Orgtbl radio tables, see @ref{Translator functions}, for a
|
||
detailed description.
|
||
@end table
|
||
|

If you don't like the automatic table editor because it gets in your

way on lines which you would like to start with @samp{|}, you can turn
|
||
it off with
|
||
|
||
@lisp
|
||
(setq org-enable-table-editor nil)
|
||
@end lisp
|
||

@noindent Then the only table command that still works is
|

@kbd{C-c C-c} to do a manual re-align.

@section Column width and alignment

@cindex narrow columns in tables

@cindex alignment in tables
|
||
|
||
The width of columns is automatically determined by the table editor. And
|
||
also the alignment of a column is determined automatically from the fraction
|
||
of number-like versus non-number fields in the column.
|
||
|
||
Sometimes a single field or a few fields need to carry more text, leading to
|
||
inconveniently wide columns. Or maybe you want to make a table with several
|
||
columns having a fixed width, regardless of content. To set@footnote{This
|
||
feature does not work on XEmacs.} the width of a column, one field anywhere
|
||
in the column may contain just the string @samp{<N>} where @samp{N} is an
|
||
integer specifying the width of the column in characters. The next re-align
|
||
will then set the width of this column to this value.
|
||
|
||
@example
|
||
@group
|
||
|---+------------------------------| |---+--------|
|
||
| | | | | <6> |
|
||

||
|---+------------------------------| |---+--------|
|
||
@end group
|
||
@end example
|
||
|
||
@noindent
|
||
Fields that are wider become clipped and end in the string @samp{=>}.
|
||
Note that the full text is still in the buffer but is hidden.
|
||
To see the full text, hold the mouse over the field---a tool-tip window
|
||
will show the full content. To edit such a field, use the command
|
||
@kbd{C-c `} (that is @kbd{C-c} followed by the backquote). This will
|
||
open a new window with the full field. Edit it and finish with @kbd{C-c
|
||
C-c}.
|
||
|
||
@vindex org-startup-align-all-tables
|
||
When visiting a file containing a table with narrowed columns, the
|
||
necessary character hiding has not yet happened, and the table needs to
|
||
be aligned before it looks nice. Setting the option
|
||
@code{org-startup-align-all-tables} will realign all tables in a file
|
||
upon visiting, but also slow down startup. You can also set this option
|
||
on a per-file basis with:
|
||
|
||
@example
|
||
#+STARTUP: align
|
||
#+STARTUP: noalign
|
||
@end example
|
||
|
||
If you would like to overrule the automatic alignment of number-rich columns
|
||
to the right and of string-rich column to the left, you can use @samp{<r>},
|
||
@samp{c}@footnote{Centering does not work inside Emacs, but it does have an
|
||
effect when exporting to HTML.} or @samp{<l>} in a similar fashion. You may
|
||
also combine alignment and field width like this: @samp{<l10>}.
|
||
|
||
Lines which only contain these formatting cookies will be removed
|
||
automatically when exporting the document.

|
||
When Org exports tables, it does so by default without vertical
|
||
lines because that is visually more satisfying in general. Occasionally
|
||
however, vertical lines can be useful to structure a table into groups
|
||
of columns, much like horizontal lines can do for groups of rows. In
|
||
order to specify column groups, you can use a special row where the
|
||
first field contains only @samp{/}. The further fields can either
|
||
contain @samp{<} to indicate that this column should start a group,
|
||
@samp{>} to indicate the end of a column, or @samp{<>} (no space between @samp{<}
|
||
and @samp{>}) to make a column
|
||
a group of its own. Boundaries between column groups will upon export be
|
||
marked with vertical lines. Here is an example:
|
||
|
||
@example
|
||
| N | N^2 | N^3 | N^4 | sqrt(n) | sqrt[4](N) |
|
||
|---+-----+-----+-----+---------+------------|
|
||

|
||
@end example
|
||
|
||
It is also sufficient to just insert the column group starters after
|
||
every vertical line you would like to have:
|
||
|
||
@example
|
||
| N | N^2 | N^3 | N^4 | sqrt(n) | sqrt[4](N) |

To compute fields in the table from other fields, formulas must

reference other fields or ranges. In Org, fields can be referenced
|
||
by name, by absolute coordinates, and by relative coordinates. To find

out what the coordinates of a field are, press @kbd{C-c ?} in that

||
field, or press @kbd{C-c @}} to toggle the display of a grid.

combination like @code{B3}, meaning the 2nd field in the 3rd row.
|

However, Org prefers@footnote{Org will understand references typed by the

column of the field which is being computed) like @code{$+1} or @code{$-2}.
|
||
@code{$<} and @code{$>} are immutable references to the first and last
|
||
column, respectively, and you can use @code{$>>>} to indicate the third
|
||
column from the right.
|
||
|
||
The row specification only counts data lines and ignores horizontal separator
|
||
lines (hlines). Like with columns, you can use absolute row numbers
|
||
@code{@@1}, @code{@@2},...@code{@@@var{N}}, and row numbers relative to the
|
||
current row like @code{@@+3} or @code{@@-1}. @code{@@<} and @code{@@>} are
|
||
immutable references the first and last@footnote{For backward compatibility
|
||
you can also use special names like @code{$LR5} and @code{$LR12} to refer in
|
||
a stable way to the 5th and 12th field in the last row of the table.
|
||
However, this syntax is deprecated, it should not be used for new documents.
|
||
Use @code{@@>$} instead.} row in the table, respectively. You may also
|
||
specify the row relative to one of the hlines: @code{@@I} refers to the first
|
||
hline, @code{@@II} to the second, etc@. @code{@@-I} refers to the first such
|
||
line above the current line, @code{@@+I} to the first such line below the
|
||
current line. You can also write @code{@@III+2} which is the second data line
|
||
after the third hline in the table.
|
||
|
||
@code{@@0} and @code{$0} refer to the current row and column, respectively,
|
||
i.e. to the row/column for the field being computed. Also, if you omit
|
||
either the column or the row part of the reference, the current row/column is
|
||
implied.
|
||
|
||
Org's references with @emph{unsigned} numbers are fixed references
|
||
in the sense that if you use the same reference in the formula for two
|
||
different fields, the same field will be referenced each time.
|
||
Org's references with @emph{signed} numbers are floating
|
||
references because the same reference operator can reference different
|
||
fields depending on the field being calculated by the formula.
|
||
|
||
Here are a few examples:

|
||
@samp{@@} in order to be interpreted correctly). Examples:
|
||
|

@example

@end example
|

@noindent Range references return a vector of values that can be fed

into Calc vector functions. Empty fields in ranges are normally
|
||
suppressed, so that the vector contains only the non-empty fields (but

see the @samp{E} mode switch below). If there are no non-empty fields,

@samp{[0]} is returned to avoid syntax errors in formulas.

@cindex syntax, of formulas
|
||
|
||
A formula can be any algebraic expression understood by the Emacs
|
||
@file{Calc} package. @b{Note that @file{calc} has the
|
||
non-standard convention that @samp{/} has lower precedence than
|
||
@samp{*}, so that @samp{a/b*c} is interpreted as @samp{a/(b*c)}.} Before
|
||
evaluation by @code{calc-eval} (@pxref{Calling Calc from
|
||
Your Programs, calc-eval, Calling Calc from Your Lisp Programs, calc, GNU
|
||
Emacs Calc Manual}),
|
||
variable substitution takes place according to the rules described above.
|
||
@cindex vectors, in table calculations
|
||
The range vectors can be directly fed into the Calc vector functions
|
||
like @samp{vmean} and @samp{vsum}.
|
||
|
||
@cindex format specifier
|
||
@cindex mode, for @file{calc}
|
||
@vindex org-calc-default-modes
|
||
A formula can contain an optional mode string after a semicolon. This
|
||
string consists of flags to influence Calc and other modes during
|
||
execution. By default, Org uses the standard Calc modes (precision
|
||
12, angular units degrees, fraction and symbolic modes off). The display
|
||
format, however, has been changed to @code{(float 8)} to keep tables
|
||
compact. The default settings can be configured using the variable
|
||
@code{org-calc-default-modes}.
|
||
|
||
@example
|
||
p20 @r{set the internal Calc calculation precision to 20 digits}
|
||
n3 s3 e2 f4 @r{Normal, scientific, engineering, or fixed}
|
||
@r{format of the result of Calc passed back to Org.}
|
||
@r{Calc formatting is unlimited in precision as}
|
||
@r{long as the Calc calculation precision is greater.}
|
||
D R @r{angle modes: degrees, radians}
|
||
F S @r{fraction and symbolic modes}
|
||
N @r{interpret all fields as numbers, use 0 for non-numbers}
|
||
E @r{keep empty fields in ranges}
|
||
L @r{literal}
|
||
@end example
|
||
|
||
@noindent
|
||
Unless you use large integer numbers or high-precision-calculation
|
||
and -display for floating point numbers you may alternatively provide a
|
||
@code{printf} format specifier to reformat the Calc result after it has been
|
||
passed back to Org instead of letting Calc already do the
|
||
formatting@footnote{The @code{printf} reformatting is limited in precision
|
||
because the value passed to it is converted into an @code{integer} or
|
||
@code{double}. The @code{integer} is limited in size by truncating the
|
||
signed value to 32 bits. The @code{double} is limited in precision to 64
|
||
bits overall which leaves approximately 16 significant decimal digits.}.
|
||
A few examples:
|
||
|
||
@example
|
||
$1+$2 @r{Sum of first and second field}
|
||
$1+$2;%.2f @r{Same, format result to two decimals}
|
||
exp($2)+exp($1) @r{Math functions can be used}
|
||
$0;%.1f @r{Reformat current cell to 1 decimal}
|
||
($3-32)*5/9 @r{Degrees F -> C conversion}
|
||
$c/$1/$cm @r{Hz -> cm conversion, using @file{constants.el}}
|
||
tan($1);Dp3s1 @r{Compute in degrees, precision 3, display SCI 1}
|
||
sin($1);Dp3%.1e @r{Same, but use printf specifier for display}
|
||
vmean($2..$7) @r{Compute column range mean, using vector function}
|
||
vmean($2..$7);EN @r{Same, but treat empty fields as 0}
|
||
taylor($3,x=7,2) @r{Taylor series of $3, at x=7, second degree}
|
||
@end example
|
||
|
||
Calc also contains a complete set of logical operations. For example
|
||
|
||
@example
|
||
if($1<20,teen,string("")) @r{"teen" if age $1 less than 20, else empty}
|
||
@end example
|

||
durations computations @ref{Durations and time values}.

@subsection Emacs Lisp forms as formulas
|
||
@cindex Lisp forms, as table formulas
|
||
|
||
It is also possible to write a formula in Emacs Lisp; this can be useful for
|
||
string manipulation and control structures, if Calc's functionality is not
|
||
enough. If a formula starts with a single-quote followed by an opening
|
||
parenthesis, then it is evaluated as a Lisp form. The evaluation should
|
||
return either a string or a number. Just as with @file{calc} formulas, you
|
||
can specify modes and a printf format after a semicolon. With Emacs Lisp
|
||
forms, you need to be conscious about the way field references are
|
||
interpolated into the form. By default, a reference will be interpolated as
|
||
a Lisp string (in double-quotes) containing the field. If you provide the
|
||
@samp{N} mode switch, all referenced elements will be numbers (non-number
|
||
fields will be zero) and interpolated as Lisp numbers, without quotes. If
|
||
you provide the @samp{L} flag, all fields will be interpolated literally,
|
||
without quotes. I.e., if you want a reference to be interpreted as a string
|
||
by the Lisp form, enclose the reference operator itself in double-quotes,
|
||
like @code{"$3"}. Ranges are inserted as space-separated fields, so you can
|
||
embed them in list or vector syntax. Here are a few examples---note how the
|
||
@samp{N} mode is used when we do computations in Lisp:
|
||
|
||
@example
|
||
@r{Swap the first two characters of the content of column 1}
|
||
'(concat (substring $1 1 2) (substring $1 0 1) (substring $1 2))
|
||
@r{Add columns 1 and 2, equivalent to Calc's @code{$1+$2}}
|
||
'(+ $1 $2);N
|
||
@r{Compute the sum of columns 1-4, like Calc's @code{vsum($1..$4)}}

'(apply '+ '($1..$4));N

||
@cindex formula, for individual table field
|
||
@cindex formula, for range of fields
|
||
|
||
To assign a formula to a particular field, type it directly into the field,
|
||
preceded by @samp{:=}, for example @samp{:=vsum(@@II..III)}. When you press
|
||
@key{TAB} or @key{RET} or @kbd{C-c C-c} with the cursor still in the field,
|
||
the formula will be stored as the formula for this field, evaluated, and the
|
||
current field will be replaced with the result.
|
||
|
||
@cindex #+TBLFM
|
||
Formulas are stored in a special line starting with @samp{#+TBLFM:} directly
|
||
below the table. If you type the equation in the 4th field of the 3rd data
|
||
line in the table, the formula will look like @samp{@@3$4=$1+$2}. When
|
||
inserting/deleting/swapping column and rows with the appropriate commands,
|
||
@i{absolute references} (but not relative ones) in stored formulas are
|
||
modified in order to still reference the same field. To avoid this from
|
||
happening, in particular in range references, anchor ranges at the table
|
||
borders (using @code{@@<}, @code{@@>}, @code{$<}, @code{$>}), or at hlines
|
||
using the @code{@@I} notation. Automatic adaptation of field references does
|
||
of cause not happen if you edit the table structure with normal editing
|
||
commands---then you must fix the equations yourself.
|
||
|
||
Instead of typing an equation into the field, you may also use the following
|
||
command
|
||
|
||
@table @kbd
|
||
@orgcmd{C-u C-c =,org-table-eval-formula}
|
||
Install a new formula for the current field. The command prompts for a
|
||
formula with default taken from the @samp{#+TBLFM:} line, applies
|
||
it to the current field, and stores it.
|
||
@end table
|
||
|
||
The left-hand side of a formula can also be a special expression in order to
|
||
assign the formula to a number of different fields. There is no keyboard
|
||
shortcut to enter such range formulas. To add them, use the formula editor
|

@cindex column formula

@cindex formula, for table column
|
||
|
||
When you assign a formula to a simple column reference like @code{$3=}, the
|
||
same formula will be used in all fields of that column, with the following
|
||
very convenient exceptions: (i) If the table contains horizontal separator
|
||
hlines, everything before the first such line is considered part of the table
|
||
@emph{header} and will not be modified by column formulas. (ii) Fields that
|
||
already get a value from a field/range formula will be left alone by column
|
||
formulas. These conditions make column formulas very easy to use.
|
||
|
||
To assign a formula to a column, type it directly into any field in the
|
||
column, preceded by an equal sign, like @samp{=$1+$2}. When you press
|
||
@key{TAB} or @key{RET} or @kbd{C-c C-c} with the cursor still in the field,
|
||
the formula will be stored as the formula for the current column, evaluated
|
||
and the current field replaced with the result. If the field contains only
|
||
@samp{=}, the previously stored formula for this column is used. For each
|
||
column, Org will only remember the most recently used formula. In the
|
||
@samp{#+TBLFM:} line, column formulas will look like @samp{$4=$1+$2}. The
|
||
left-hand side of a column formula can not be the name of column, it must be
|
||
the numeric column reference or @code{$>}.
|
||
|
||
Instead of typing an equation into the field, you may also use the
|
||
following command:
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c =,org-table-eval-formula}
|
||
Install a new formula for the current column and replace current field with
|
||
the result of the formula. The command prompts for a formula, with default
|
||
taken from the @samp{#+TBLFM} line, applies it to the current field and
|
||
stores it. With a numeric prefix argument(e.g.@: @kbd{C-5 C-c =}) the command
|
||
will apply it to that many consecutive fields in the current column.

converts references to the standard format (like @code{B3} or @code{D&})
|
||
if possible. If you prefer to only work with the internal format (like

Edit all formulas for the current table in a special buffer, where the
|
||
formulas will be displayed one per line. If the current field has an
|
||
active formula, the cursor in the formula editor will mark it.
|
||
While inside the special buffer, Org will automatically highlight
|
||
any field or range reference at the cursor position. You may edit,
|
||
remove and add formulas, and use the following commands:
|
||
@table @kbd
|
||
@orgcmdkkc{C-c C-c,C-x C-s,org-table-fedit-finish}
|
||
Exit the formula editor and store the modified formulas. With @kbd{C-u}
|
||
prefix, also apply the new formulas to the entire table.
|
||
@orgcmd{C-c C-q,org-table-fedit-abort}
|
||
Exit the formula editor without installing changes.
|
||
@orgcmd{C-c C-r,org-table-fedit-toggle-ref-type}
|
||
Toggle all references in the formula editor between standard (like
|
||
@code{B3}) and internal (like @code{@@3$2}).
|
||
@orgcmd{@key{TAB},org-table-fedit-lisp-indent}
|
||
Pretty-print or indent Lisp formula at point. When in a line containing
|
||
a Lisp formula, format the formula according to Emacs Lisp rules.
|
||
Another @key{TAB} collapses the formula back again. In the open
|
||
formula, @key{TAB} re-indents just like in Emacs Lisp mode.
|
||
@orgcmd{M-@key{TAB},lisp-complete-symbol}
|
||
Complete Lisp symbols, just like in Emacs Lisp mode.

|
||
@findex org-table-fedit-ref-right
|
||
@item S-@key{up}/@key{down}/@key{left}/@key{right}
|
||
Shift the reference at point. For example, if the reference is
|
||
@code{B3} and you press @kbd{S-@key{right}}, it will become @code{C3}.
|
||
This also works for relative references and for hline references.
|
||
@orgcmdkkcc{M-S-@key{up},M-S-@key{down},org-table-fedit-line-up,org-table-fedit-line-down}
|
||
Move the test line for column formulas in the Org buffer up and
|
||
down.
|
||
@orgcmdkkcc{M-@key{up},M-@key{down},org-table-fedit-scroll-down,org-table-fedit-scroll-up}
|
||
Scroll the window displaying the table.
|
||
@kindex C-c @}

|

Turn the coordinate grid in the table on and off.

|

|

Making a table field blank does not remove the formula associated with
|
||
the field, because that is stored in a different line (the @samp{#+TBLFM}
|
||
line)---during the next recalculation the field will be filled again.
|
||
To remove a formula from a field, you have to give an empty reply when
|
||
prompted for the formula, or to edit the @samp{#+TBLFM} line.
|
||
|
||
@kindex C-c C-c
|
||
You may edit the @samp{#+TBLFM} directly and re-apply the changed
|
||
equations with @kbd{C-c C-c} in that line or with the normal
|
||
recalculation commands in the table.

Recalculation of a table is normally not automatic, but needs to be
|
||
triggered by a command. See @ref{Advanced features}, for a way to make
|
||
recalculation at least semi-automatic.
|
||
|
||
In order to recalculate a line of a table or the entire table, use the
|
||
following commands:
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c *,org-table-recalculate}
|
||
Recalculate the current row by first applying the stored column formulas
|
||
from left to right, and all field/range formulas in the current row.
|
||
@c
|
||
@kindex C-u C-c *
|
||
@item C-u C-c *
|
||
@kindex C-u C-c C-c
|
||
@itemx C-u C-c C-c
|
||
Recompute the entire table, line by line. Any lines before the first
|
||
hline are left alone, assuming that these are part of the table header.
|
||
@c
|
||
@orgcmdkkc{C-u C-u C-c *,C-u C-u C-c C-c,org-table-iterate}
|
||
Iterate the table by recomputing it until no further changes occur.
|
||
This may be necessary if some computed fields use the value of other
|
||
fields that are computed @i{later} in the calculation sequence.
|
||
@item M-x org-table-recalculate-buffer-tables
|

@noindent @b{Important}: please note that for these special tables,
|
||
recalculating the table with @kbd{C-u C-c *} will only affect rows that
|
||
are marked @samp{#} or @samp{*}, and fields that have a formula assigned
|
||
to the field itself. The column formulas are not applied in rows with
|
||
empty first field.
|
||
|
||
@cindex marking characters, tables
|
||
The marking characters have the following meaning:
|
||
@table @samp
|
||
@item !
|
||
The fields in this line define names for the columns, so that you may
|
||
refer to a column as @samp{$Tot} instead of @samp{$6}.
|
||
@item ^
|
||
This row defines names for the fields @emph{above} the row. With such
|
||
a definition, any formula in the table may use @samp{$m1} to refer to
|
||
the value @samp{10}. Also, if you assign a formula to a names field, it
|
||
will be stored as @samp{$name=...}.
|
||
@item _
|
||
Similar to @samp{^}, but defines names for the fields in the row
|
||
@emph{below}.
|
||
@item $
|
||
Fields in this row can define @emph{parameters} for formulas. For
|
||
example, if a field in a @samp{$} row contains @samp{max=50}, then
|
||
formulas in this table can refer to the value 50 using @samp{$max}.
|
||
Parameters work exactly like constants, only that they can be defined on
|
||
a per-table basis.
|
||
@item #
|
||
Fields in this row are automatically recalculated when pressing
|
||
@key{TAB} or @key{RET} or @kbd{S-@key{TAB}} in this row. Also, this row
|
||
is selected for a global recalculation with @kbd{C-u C-c *}. Unmarked
|
||
lines will be left alone by this command.
|
||
@item *
|
||
Selects this line for global recalculation with @kbd{C-u C-c *}, but
|
||
not for automatic recalculation. Use this when automatic
|
||
recalculation slows down editing too much.
|
||
@item
|
||
Unmarked lines are exempt from recalculation with @kbd{C-u C-c *}.
|
||
All lines that should be recalculated should be marked with @samp{#}
|
||
or @samp{*}.
|
||
@item /
|
||
Do not export this line. Useful for lines that contain the narrowing
|
||
@samp{<N>} markers or column group markers.

@cindex format, of links
|

Org will recognize plain URL-like links and activate them as

clickable links. The general link format, however, looks like this:
|
||
|
||
@example
|
||
[[link][description]] @r{or alternatively} [[link]]
|
||
@end example
|
||
|
||
@noindent
|
||
Once a link in the buffer is complete (all brackets present), Org
|
||
will change the display so that @samp{description} is displayed instead
|
||
of @samp{[[link][description]]} and @samp{link} is displayed instead of
|
||
@samp{[[link]]}. Links will be highlighted in the face @code{org-link},
|
||
which by default is an underlined face. You can directly edit the
|
||
visible part of a link. Note that this can be either the @samp{link}
|
||
part (if there is no description) or the @samp{description} part. To
|
||
edit also the invisible @samp{link} part, use @kbd{C-c C-l} with the
|
||
cursor on the link.
|
||
|
||
If you place the cursor at the beginning or just behind the end of the
|
||
displayed text and press @key{BACKSPACE}, you will remove the
|
||
(invisible) bracket at that location. This makes the link incomplete
|
||
and the internals are again displayed as plain text. Inserting the
|
||
missing bracket hides the link internals again. To show the
|
||
internal structure of all links, use the menu entry
|
||
@code{Org->Hyperlinks->Literal links}.

@cindex property, CUSTOM_ID
|
||
If the link does not look like a URL, it is considered to be internal in the
|
||
current file. The most important case is a link like
|
||
@samp{[[#my-custom-id]]} which will link to the entry with the
|
||
@code{CUSTOM_ID} property @samp{my-custom-id}. Such custom IDs are very good
|
||
for HTML export (@pxref{HTML export}) where they produce pretty section
|
||
links. You are responsible yourself to make sure these custom IDs are unique
|
||
in a file.
|
||
|
||
Links such as @samp{[[My Target]]} or @samp{[[My Target][Find my target]]}
|
||
lead to a text search in the current file.
|
||
|
||
The link can be followed with @kbd{C-c C-o} when the cursor is on the link,
|
||
or with a mouse click (@pxref{Handling links}). Links to custom IDs will
|
||
point to the corresponding headline. The preferred match for a text link is
|
||
a @i{dedicated target}: the same string in double angular brackets. Targets
|
||
may be located anywhere; sometimes it is convenient to put them into a
|
||
comment line. For example
|
||
|
||
@example
|
||
# <<My Target>>
|
||
@end example
|
||
|
||
@noindent In HTML export (@pxref{HTML export}), such targets will become
|
||
named anchors for direct access through @samp{http} links@footnote{Note that
|
||
text before the first headline is usually not exported, so the first such
|
||
target should be after the first headline, or in the line directly before the
|
||
first headline.}.
|
||
|
||
If no dedicated target exists, Org will search for a headline that is exactly
|
||
the link text but may also include a TODO keyword and tags@footnote{To insert
|
||
a link targeting a headline, in-buffer completion can be used. Just type a
|
||
star followed by a few optional letters into the buffer and press
|
||
@kbd{M-@key{TAB}}. All headlines in the current buffer will be offered as
|
||
completions.}. In non-Org files, the search will look for the words in the
|
||
link text. In the above example the search would be for @samp{my target}.
|
||
|
||
Following a link pushes a mark onto Org's own mark ring. You can
|
||
return to the previous position with @kbd{C-c &}. Using this command
|
||
several times in direct succession goes back to positions recorded
|
||
earlier.

Org can automatically turn any occurrences of certain target names

text connects to the target radioing its position. Radio targets are
|
||
enclosed by triple angular brackets. For example, a target @samp{<<<My
|
||
Target>>>} causes each occurrence of @samp{my target} in normal text to
|
||
become activated as a link. The Org file is scanned automatically
|
||
for radio targets only when the file is first loaded into Emacs. To

update the target list during editing, press @kbd{C-c C-c} with the

For customizing Org to add new link types @ref{Adding hyperlink types}.
|
||
|
||
A link should be enclosed in double brackets and may contain a
|
||
descriptive text to be displayed instead of the URL (@pxref{Link
|
||
format}), for example:
|
||
|
||
@example
|
||
[[http://www.gnu.org/software/emacs/][GNU Emacs]]
|
||
@end example
|
||
|
||
@noindent
|
||
If the description is a file name or URL that points to an image, HTML
|
||
export (@pxref{HTML export}) will inline the image as a clickable
|
||
button. If there is no description at all and the link points to an
|
||
image,
|
||
that image will be inlined into the exported HTML file.
|
||
|
||
@cindex square brackets, around links
|
||
@cindex plain text external links
|
||
Org also finds external links in the normal text and activates them
|
||
as links. If spaces must be part of the link (for example in
|
||
@samp{bbdb:Richard Stallman}), or if you need to remove ambiguities
|
||
about the end of the link, enclose them in square brackets.

@node Handling links, Using links outside Org, External links, Hyperlinks
|

@section Handling links
|
||
@cindex links, handling
|
||
|
||
Org provides methods to create a link in the correct syntax, to
|
||
insert it into an Org file, and to follow the link.
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c l,org-store-link}
|
||
@cindex storing links
|
||
Store a link to the current location. This is a @emph{global} command (you
|
||
must create the key binding yourself) which can be used in any buffer to
|
||
create a link. The link will be stored for later insertion into an Org
|
||
buffer (see below). What kind of link will be created depends on the current
|
||
buffer:
|
||
|
||
@b{Org mode buffers}@*
|
||
For Org files, if there is a @samp{<<target>>} at the cursor, the link points
|
||
to the target. Otherwise it points to the current headline, which will also
|
||
be the description@footnote{If the headline contains a timestamp, it will be
|
||
removed from the link and result in a wrong link -- you should avoid putting
|
||
timestamp in the headline.}.
|
||
|
||
@vindex org-link-to-org-use-id
|
||
@cindex property, CUSTOM_ID
|
||
@cindex property, ID
|
||
If the headline has a @code{CUSTOM_ID} property, a link to this custom ID
|
||
will be stored. In addition or alternatively (depending on the value of
|
||
@code{org-link-to-org-use-id}), a globally unique @code{ID} property will be
|
||
created and/or used to construct a link. So using this command in Org
|
||
buffers will potentially create two links: a human-readable from the custom
|
||
ID, and one that is globally unique and works even if the entry is moved from
|
||
file to file. Later, when inserting the link, you need to decide which one
|
||
to use.
|
||
|
||
@b{Email/News clients: VM, Rmail, Wanderlust, MH-E, Gnus}@*
|
||
Pretty much all Emacs mail clients are supported. The link will point to the
|
||
current article, or, in some GNUS buffers, to the group. The description is
|
||
constructed from the author and the subject.
|
||
|
||
@b{Web browsers: W3 and W3M}@*
|
||
Here the link will be the current URL, with the page title as description.
|
||
|
||
@b{Contacts: BBDB}@*
|
||
Links created in a BBDB buffer will point to the current entry.
|
||
|
||
@b{Chat: IRC}@*
|
||
@vindex org-irc-link-to-logs
|
||
For IRC links, if you set the variable @code{org-irc-link-to-logs} to
|
||
@code{t}, a @samp{file:/} style link to the relevant point in the logs for
|
||
the current conversation is created. Otherwise an @samp{irc:/} style link to
|
||
the user/channel/server under the point will be stored.
|
||
|
||
@b{Other files}@*
|
||
For any other files, the link will point to the file, with a search string
|
||
(@pxref{Search options}) pointing to the contents of the current line. If
|
||
there is an active region, the selected words will form the basis of the
|
||
search string. If the automatically created link is not working correctly or
|
||
accurately enough, you can write custom functions to select the search string
|
||
and to do the search for particular file types---see @ref{Custom searches}.
|
||
The key binding @kbd{C-c l} is only a suggestion---see @ref{Installation}.
|
||
|
||
@b{Agenda view}@*
|
||
When the cursor is in an agenda view, the created link points to the
|
||
entry referenced by the current line.

@orgcmd{C-c C-l,org-insert-link}
|

@cindex link completion
|
||
@cindex completion, of links
|
||
@cindex inserting links
|
||
@vindex org-keep-stored-link-after-insertion
|
||
Insert a link@footnote{ Note that you don't have to use this command to
|
||
insert a link. Links in Org are plain text, and you can type or paste them
|
||
straight into the buffer. By using this command, the links are automatically
|
||
enclosed in double brackets, and you will be asked for the optional
|
||
descriptive text.}. This prompts for a link to be inserted into the buffer.
|
||
You can just type a link, using text for an internal link, or one of the link
|
||
type prefixes mentioned in the examples above. The link will be inserted
|
||
into the buffer@footnote{After insertion of a stored link, the link will be
|
||
removed from the list of stored links. To keep it in the list later use, use
|
||
a triple @kbd{C-u} prefix argument to @kbd{C-c C-l}, or configure the option
|
||
@code{org-keep-stored-link-after-insertion}.}, along with a descriptive text.
|
||
If some text was selected when this command is called, the selected text
|
||
becomes the default description.
|
||
|
||
@b{Inserting stored links}@*
|
||
All links stored during the
|
||
current session are part of the history for this prompt, so you can access
|
||
them with @key{up} and @key{down} (or @kbd{M-p/n}).
|
||
|
||
@b{Completion support}@* Completion with @key{TAB} will help you to insert
|
||
valid link prefixes like @samp{http:} or @samp{ftp:}, including the prefixes
|
||
defined through link abbreviations (@pxref{Link abbreviations}). If you
|
||
press @key{RET} after inserting only the @var{prefix}, Org will offer
|
||
specific completion support for some link types@footnote{This works by
|
||
calling a special function @code{org-PREFIX-complete-link}.} For
|
||
example, if you type @kbd{file @key{RET}}, file name completion (alternative
|
||
access: @kbd{C-u C-c C-l}, see below) will be offered, and after @kbd{bbdb
|
||
@key{RET}} you can complete contact names.
|
||
@orgkey C-u C-c C-l
|
||
@cindex file name completion
|
||
@cindex completion, of file names
|
||
When @kbd{C-c C-l} is called with a @kbd{C-u} prefix argument, a link to
|
||
a file will be inserted and you may use file name completion to select
|
||
the name of the file. The path to the file is inserted relative to the
|
||
directory of the current Org file, if the linked file is in the current
|
||
directory or in a sub-directory of it, or if the path is written relative
|
||
to the current directory using @samp{../}. Otherwise an absolute path
|
||
is used, if possible with @samp{~/} for your home directory. You can
|
||
force an absolute path with two @kbd{C-u} prefixes.
|
||
@c
|
||
@item C-c C-l @ @r{(with cursor on existing link)}
|
||
When the cursor is on an existing link, @kbd{C-c C-l} allows you to edit the
|
||
link and description parts of the link.
|
||
@c
|
||
@cindex following links
|
||
@orgcmd{C-c C-o,org-open-at-point}
|
||
@vindex org-file-apps
|
||
@vindex org-link-frame-setup
|
||
Open link at point. This will launch a web browser for URLs (using
|
||
@command{browse-url-at-point}), run VM/MH-E/Wanderlust/Rmail/Gnus/BBDB for
|
||
the corresponding links, and execute the command in a shell link. When the
|
||
cursor is on an internal link, this command runs the corresponding search.
|
||
When the cursor is on a TAG list in a headline, it creates the corresponding
|
||
TAGS view. If the cursor is on a timestamp, it compiles the agenda for that
|
||
date. Furthermore, it will visit text and remote files in @samp{file:} links
|
||
with Emacs and select a suitable application for local non-text files.
|
||
Classification of files is based on file extension only. See option
|
||
@code{org-file-apps}. If you want to override the default application and
|
||
visit the file with Emacs, use a @kbd{C-u} prefix. If you want to avoid
|
||
opening in Emacs, use a @kbd{C-u C-u} prefix.@*
|
||
If the cursor is on a headline, but not on a link, offer all links in the
|
||
headline and entry text. If you want to setup the frame configuration for
|
||
following links, customize @code{org-link-frame-setup}.
|
||
|
||
@orgkey @key{RET}
|
||
@vindex org-return-follows-link
|
||
When @code{org-return-follows-link} is set, @kbd{@key{RET}} will also follow
|
||
the link at point.
|
||
@c
|
||
@kindex mouse-2
|
||
@kindex mouse-1
|
||
@item mouse-2
|
||
@itemx mouse-1
|
||
On links, @kbd{mouse-2} will open the link just as @kbd{C-c C-o}
|
||
would. Under Emacs 22 and later, @kbd{mouse-1} will also follow a link.
|
||
@c
|
||
@kindex mouse-3
|
||
@item mouse-3
|
||
@vindex org-display-internal-link-with-indirect-buffer
|
||
Like @kbd{mouse-2}, but force file links to be opened with Emacs, and
|
||
internal links to be displayed in another window@footnote{See the
|
||
variable @code{org-display-internal-link-with-indirect-buffer}}.
|
||
@c
|

||
@vindex org-startup-with-inline-images
|
||
@cindex @code{inlineimages}, STARTUP keyword
|
||
@cindex @code{noinlineimages}, STARTUP keyword
|
||
Toggle the inline display of linked images. Normally this will only inline
|
||
images that have no description part in the link, i.e.@: images that will also
|
||
be inlined during export. When called with a prefix argument, also display
|
||
images that do have a link description. You can ask for inline images to be
|
||
displayed at startup by configuring the variable
|
||
@code{org-startup-with-inline-images}@footnote{with corresponding
|
||
@code{#+STARTUP} keywords @code{inlineimages} and @code{inlineimages}}.
|
||
@orgcmd{C-c %,org-mark-ring-push}
|
||
@cindex mark ring
|
||
Push the current position onto the mark ring, to be able to return
|
||
easily. Commands following an internal link do this automatically.
|
||
@c
|
||
@orgcmd{C-c &,org-mark-ring-goto}
|
||
@cindex links, returning to
|
||
Jump back to a recorded position. A position is recorded by the
|
||
commands following internal links, and by @kbd{C-c %}. Using this
|
||
command several times in direct succession moves through a ring of
|
||
previously recorded positions.
|
||
@c
|
||
@orgcmdkkcc{C-c C-x C-n,C-c C-x C-p,org-next-link,org-previous-link}
|
||
@cindex links, finding next/previous
|
||
Move forward/backward to the next link in the buffer. At the limit of
|
||
the buffer, the search fails once, and then wraps around. The key
|
||
bindings for this are really too long; you might want to bind this also
|
||
to @kbd{C-n} and @kbd{C-p}

|

|

You can insert and follow links that have Org syntax not only in
|
||
Org, but in any Emacs buffer. For this, you should create two
|
||
global commands, like this (please select suitable global keys
|
||
yourself):
|
||
|
||
@lisp
|
||
(global-set-key "\C-c L" 'org-insert-link-global)

@cindex link abbreviations
|
||
@cindex abbreviation, links
|
||
|
||
Long URLs can be cumbersome to type, and often many similar links are
|
||
needed in a document. For this you can use link abbreviations. An
|
||
abbreviated link looks like this
|
||
|
||
@example
|
||
[[linkword:tag][description]]
|
||
@end example
|
||
|
||
@noindent
|
||
@vindex org-link-abbrev-alist
|
||
where the tag is optional.
|
||
The @i{linkword} must be a word, starting with a letter, followed by
|
||
letters, numbers, @samp{-}, and @samp{_}. Abbreviations are resolved
|
||
according to the information in the variable @code{org-link-abbrev-alist}
|
||
that relates the linkwords to replacement text. Here is an example:
|
||
|
||
@smalllisp
|
||
@group
|
||
(setq org-link-abbrev-alist
|
||
'(("bugzilla" . "http://10.1.2.9/bugzilla/show_bug.cgi?id=")
|
||
("google" . "http://www.google.com/search?q=")
|
||
("gmap" . "http://maps.google.com/maps?q=%s")
|
||
("omap" . "http://nominatim.openstreetmap.org/search?q=%s&polygon=1")
|
||
("ads" . "http://adsabs.harvard.edu/cgi-bin/nph-abs_connect?author=%s&db_key=AST")))
|
||
@end group
|
||
@end smalllisp
|
||
|
||
If the replacement text contains the string @samp{%s}, it will be
|
||
replaced with the tag. Otherwise the tag will be appended to the string
|
||
in order to create the link. You may also specify a function that will
|
||
be called with the tag as the only argument to create the link.
|
||
|
||
With the above setting, you could link to a specific bug with
|
||
@code{[[bugzilla:129]]}, search the web for @samp{OrgMode} with
|
||
@code{[[google:OrgMode]]}, show the map location of the Free Software
|
||
Foundation @code{[[gmap:51 Franklin Street, Boston]]} or of Carsten office
|
||
@code{[[omap:Science Park 904, Amsterdam, The Netherlands]]} and find out
|
||
what the Org author is doing besides Emacs hacking with
|
||
@code{[[ads:Dominik,C]]}.
|
||
|
||
If you need special abbreviations just for a single Org buffer, you
|
||
can define them in the file with
|
||
|
||
@cindex #+LINK
|
||
@example
|
||
#+LINK: bugzilla http://10.1.2.9/bugzilla/show_bug.cgi?id=
|
||
#+LINK: google http://www.google.com/search?q=%s
|
||
@end example
|
||
|
||
@noindent
|
||
In-buffer completion (@pxref{Completion}) can be used after @samp{[} to
|
||
complete link abbreviations. You may also define a function
|
||
@code{org-PREFIX-complete-link} that implements special (e.g.@: completion)
|
||
support for inserting such a link with @kbd{C-c C-l}. Such a function should
|
||
not accept any arguments, and return the full link with prefix.

|

|
||
File links can contain additional information to make Emacs jump to a
|
||
particular location in the file when following a link. This can be a
|
||
line number or a search option after a double@footnote{For backward
|
||
compatibility, line numbers can also follow a single colon.} colon. For
|
||
example, when the command @kbd{C-c l} creates a link (@pxref{Handling
|
||
links}) to a file, it encodes the words in the current line as a search
|
||
string that can be used to find this line back later when following the
|
||
link with @kbd{C-c C-o}.
|
||
|
||
Here is the syntax of the different ways to attach a search to a file
|
||
link, together with an explanation:
|
||
|
||
@example
|
||
[[file:~/code/main.c::255]]
|
||
[[file:~/xx.org::My Target]]
|
||
[[file:~/xx.org::*My Target]]
|
||
[[file:~/xx.org::#my-custom-id]]
|
||
[[file:~/xx.org::/regexp/]]
|
||
@end example
|
||
|
||
@table @code
|
||
@item 255
|
||
Jump to line 255.
|
||
@item My Target
|
||
Search for a link target @samp{<<My Target>>}, or do a text search for
|
||
@samp{my target}, similar to the search in internal links, see
|
||
@ref{Internal links}. In HTML export (@pxref{HTML export}), such a file
|
||
link will become an HTML reference to the corresponding named anchor in
|
||
the linked file.
|
||
@item *My Target
|
||
In an Org file, restrict search to headlines.
|
||
@item #my-custom-id
|
||
Link to a heading with a @code{CUSTOM_ID} property
|
||
@item /regexp/
|
||
Do a regular expression search for @code{regexp}. This uses the Emacs
|
||
command @code{occur} to list all matches in a separate window. If the
|
||
target file is in Org mode, @code{org-occur} is used to create a
|
||
sparse tree with the matches.
|
||
@c If the target file is a directory,
|
||
@c @code{grep} will be used to search all files in the directory.
|
||
@end table
|
||
|
||
As a degenerate case, a file link with an empty file name can be used
|
||
to search the current file. For example, @code{[[file:::find me]]} does
|
||
a search for @samp{find me} in the current file, just as
|
||
@samp{[[find me]]} would.

||
|
||
The default mechanism for creating search strings and for doing the
|
||
actual search related to a file link may not work correctly in all
|
||
cases. For example, Bib@TeX{} database files have many entries like
|
||
@samp{year="1993"} which would not result in good search strings,
|
||
because the only unique identification for a Bib@TeX{} entry is the
|
||
citation key.
|
||
|
||
@vindex org-create-file-search-functions
|
||
@vindex org-execute-file-search-functions
|
||
If you come across such a problem, you can write custom functions to set
|
||
the right search string for a particular file type, and to do the search
|
||
for the string in the file. Using @code{add-hook}, these functions need
|
||
to be added to the hook variables
|
||
@code{org-create-file-search-functions} and
|
||
@code{org-execute-file-search-functions}. See the docstring for these
|
||
variables for more information. Org actually uses this mechanism
|
||
for Bib@TeX{} database files, and you can use the corresponding code as
|
||
an implementation example. See the file @file{org-bibtex.el}.

Org mode does not maintain TODO lists as separate documents@footnote{Of
|
||
course, you can make a document that contains only long lists of TODO items,
|
||
but this is not required.}. Instead, TODO items are an integral part of the
|
||
notes file, because TODO items usually come up while taking notes! With Org
|
||
mode, simply mark any entry in a tree as being a TODO item. In this way,
|
||
information is not duplicated, and the entire context from which the TODO
|
||
item emerged is always present.
|
||
|
||
Of course, this technique for managing TODO items scatters them
|
||
throughout your notes file. Org mode compensates for this by providing
|
||
methods to give you an overview of all the things that you have to do.

|
||
|
||
Any headline becomes a TODO item when it starts with the word
|
||
@samp{TODO}, for example:
|
||
|
||
@example
|
||
*** TODO Write letter to Sam Fortune
|
||
@end example
|
||
|
||
@noindent
|
||
The most important commands to work with TODO entries are:
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-t,org-todo}
|
||
@cindex cycling, of TODO states
|
||
Rotate the TODO state of the current item among
|
||
|
||
@example
|
||
,-> (unmarked) -> TODO -> DONE --.
|
||
'--------------------------------'
|
||
@end example
|
||
|
||
The same rotation can also be done ``remotely'' from the timeline and
|
||
agenda buffers with the @kbd{t} command key (@pxref{Agenda commands}).
|
||
|
||
@orgkey{C-u C-c C-t}
|
||
Select a specific keyword using completion or (if it has been set up)
|
||
the fast selection interface. For the latter, you need to assign keys
|
||
to TODO states, see @ref{Per-file keywords}, and @ref{Setting tags}, for
|
||
more information.
|
||
|
||
@kindex S-@key{right}

@vindex org-treat-S-cursor-todo-selection-as-state-change
|

Select the following/preceding TODO state, similar to cycling. Useful
|

mostly if more than two TODO states are possible (@pxref{TODO
|

extensions}). See also @ref{Conflicts}, for a discussion of the interaction
|

@orgcmd{C-c / t,org-show-todo-key}
|

@cindex sparse tree, for TODO
|
||
@vindex org-todo-keywords
|
||
View TODO items in a @emph{sparse tree} (@pxref{Sparse trees}). Folds the
|
||
entire buffer, but shows all TODO items (with not-DONE state) and the
|
||
headings hierarchy above them. With a prefix argument (or by using @kbd{C-c
|
||
/ T}), search for a specific TODO. You will be prompted for the keyword, and
|
||
you can also give a list of keywords like @code{KWD1|KWD2|...} to list
|
||
entries that match any one of these keywords. With a numeric prefix argument
|
||
N, show the tree for the Nth keyword in the variable
|
||
@code{org-todo-keywords}. With two prefix arguments, find all TODO states,
|
||
both un-done and done.
|
||
@orgcmd{C-c a t,org-todo-list}
|
||
Show the global TODO list. Collects the TODO items (with not-DONE states)
|
||
from all agenda files (@pxref{Agenda Views}) into a single buffer. The new
|
||
buffer will be in @code{agenda-mode}, which provides commands to examine and
|
||
manipulate the TODO entries from the new buffer (@pxref{Agenda commands}).
|
||
@xref{Global TODO list}, for more information.

|
||
@cindex workflow states as TODO keywords
|
||
|
||
You can use TODO keywords to indicate different @emph{sequential} states
|
||
in the process of working on an item, for example@footnote{Changing
|
||
this variable only becomes effective after restarting Org mode in a
|
||
buffer.}:
|
||
|
||
@lisp
|
||
(setq org-todo-keywords
|
||
'((sequence "TODO" "FEEDBACK" "VERIFY" "|" "DONE" "DELEGATED")))
|
||
@end lisp
|
||
|
||
The vertical bar separates the TODO keywords (states that @emph{need
|
||
action}) from the DONE states (which need @emph{no further action}). If
|
||
you don't provide the separator bar, the last state is used as the DONE
|
||
state.
|
||
@cindex completion, of TODO keywords
|
||
With this setup, the command @kbd{C-c C-t} will cycle an entry from TODO
|
||
to FEEDBACK, then to VERIFY, and finally to DONE and DELEGATED. You may
|
||
also use a numeric prefix argument to quickly select a specific state. For
|
||
example @kbd{C-3 C-c C-t} will change the state immediately to VERIFY.
|
||
Or you can use @kbd{S-@key{left}} to go backward through the sequence. If you
|
||
define many keywords, you can use in-buffer completion
|
||
(@pxref{Completion}) or even a special one-key selection scheme
|
||
(@pxref{Fast access to TODO states}) to insert these words into the
|
||
buffer. Changing a TODO state can be logged with a timestamp, see
|
||
@ref{Tracking TODO state changes}, for more information.
|
||
|
||
@node TODO types, Multiple sets in one file, Workflow states, TODO extensions

@subsection TODO keywords as types
|
||
@cindex TODO types
|

@cindex names as TODO keywords
|
||
@cindex types as TODO keywords
|
||
|
||
The second possibility is to use TODO keywords to indicate different
|
||
@emph{types} of action items. For example, you might want to indicate
|
||
that items are for ``work'' or ``home''. Or, when you work with several
|
||
people on a single project, you might want to assign action items
|
||
directly to persons, by using their names as TODO keywords. This would
|
||
be set up like this:
|
||
|
||
@lisp
|
||
(setq org-todo-keywords '((type "Fred" "Sara" "Lucy" "|" "DONE")))
|
||
@end lisp
|
||
|
||
In this case, different keywords do not indicate a sequence, but rather
|
||
different types. So the normal work flow would be to assign a task to a
|
||
person, and later to mark it DONE. Org mode supports this style by adapting
|
||
the workings of the command @kbd{C-c C-t}@footnote{This is also true for the
|
||
@kbd{t} command in the timeline and agenda buffers.}. When used several
|
||
times in succession, it will still cycle through all names, in order to first
|
||
select the right type for a task. But when you return to the item after some
|
||
time and execute @kbd{C-c C-t} again, it will switch from any name directly
|
||
to DONE. Use prefix arguments or completion to quickly select a specific
|
||
name. You can also review the items of a specific TODO type in a sparse tree
|
||
by using a numeric prefix to @kbd{C-c / t}. For example, to see all things
|
||
Lucy has to do, you would use @kbd{C-3 C-c / t}. To collect Lucy's items
|
||
from all agenda files into a single buffer, you would use the numeric prefix
|
||
argument as well when creating the global TODO list: @kbd{C-3 C-c a t}.
|
||
|
||
@node Multiple sets in one file, Fast access to TODO states, TODO types, TODO extensions
|
||
@subsection Multiple keyword sets in one file
|
||
@cindex TODO keyword sets
|
||
|
||
Sometimes you may want to use different sets of TODO keywords in
|
||
parallel. For example, you may want to have the basic
|
||
@code{TODO}/@code{DONE}, but also a workflow for bug fixing, and a
|
||
separate state indicating that an item has been canceled (so it is not
|
||
DONE, but also does not require action). Your setup would then look
|
||
like this:
|
||
|
||
@lisp
|
||
(setq org-todo-keywords
|
||
'((sequence "TODO" "|" "DONE")
|
||
(sequence "REPORT" "BUG" "KNOWNCAUSE" "|" "FIXED")
|
||
(sequence "|" "CANCELED")))
|
||
@end lisp
|
||
|
||
The keywords should all be different, this helps Org mode to keep track
|
||
of which subsequence should be used for a given entry. In this setup,
|
||
@kbd{C-c C-t} only operates within a subsequence, so it switches from
|
||
@code{DONE} to (nothing) to @code{TODO}, and from @code{FIXED} to
|
||
(nothing) to @code{REPORT}. Therefore you need a mechanism to initially
|
||
select the correct sequence. Besides the obvious ways like typing a
|
||
keyword or using completion, you may also apply the following commands:
|
||
|
||
@table @kbd
|
||
@kindex C-S-@key{right}
|
||
@kindex C-S-@key{left}
|
||
@kindex C-u C-u C-c C-t
|
||
@item C-u C-u C-c C-t
|
||
@itemx C-S-@key{right}
|
||
@itemx C-S-@key{left}
|
||
These keys jump from one TODO subset to the next. In the above example,
|
||
@kbd{C-u C-u C-c C-t} or @kbd{C-S-@key{right}} would jump from @code{TODO} or
|
||
@code{DONE} to @code{REPORT}, and any of the words in the second row to
|
||
@code{CANCELED}. Note that the @kbd{C-S-} key binding conflict with
|
||
@code{shift-selection-mode} (@pxref{Conflicts}).
|
||
@kindex S-@key{right}
|
||
@kindex S-@key{left}
|
||
@item S-@key{right}
|
||
@itemx S-@key{left}
|
||
@kbd{S-@key{<left>}} and @kbd{S-@key{<right>}} and walk through @emph{all}
|
||
keywords from all sets, so for example @kbd{S-@key{<right>}} would switch
|
||
from @code{DONE} to @code{REPORT} in the example above. See also
|
||
@ref{Conflicts}, for a discussion of the interaction with
|
||
@code{shift-selection-mode}.

@subsection Fast access to TODO states
|
||
|
||
If you would like to quickly change an entry to an arbitrary TODO state
|
||
instead of cycling through the states, you can set up keys for
|
||
single-letter access to the states. This is done by adding the section
|
||
key after each keyword, in parentheses. For example:
|
||
|
||
@lisp
|
||
(setq org-todo-keywords
|
||
'((sequence "TODO(t)" "|" "DONE(d)")
|
||
(sequence "REPORT(r)" "BUG(b)" "KNOWNCAUSE(k)" "|" "FIXED(f)")
|
||
(sequence "|" "CANCELED(c)")))
|
||
@end lisp
|
||
|
||
@vindex org-fast-tag-selection-include-todo
|
||

|
||
will be switched to this state. @kbd{SPC} can be used to remove any TODO
|
||
keyword from an entry.@footnote{Check also the variable
|
||
@code{org-fast-tag-selection-include-todo}, it allows you to change the TODO
|
||
state through the tags interface (@pxref{Setting tags}), in case you like to
|
||
mingle the two concepts. Note that this means you need to come up with
|
||
unique keys across both sets of keywords.}

It can be very useful to use different aspects of the TODO mechanism in
|
||
different files. For file-local settings, you need to add special lines
|
||
to the file which set the keywords and interpretation for that file
|
||
only. For example, to set one of the two examples discussed above, you
|
||
need one of the following lines, starting in column zero anywhere in the
|
||
file:
|
||
|
||
@example
|
||
#+TODO: TODO FEEDBACK VERIFY | DONE CANCELED
|
||
@end example
|
||
@noindent (you may also write @code{#+SEQ_TODO} to be explicit about the
|
||
interpretation, but it means the same as @code{#+TODO}), or
|
||
@example
|
||
#+TYP_TODO: Fred Sara Lucy Mike | DONE
|
||
@end example
|
||
|
||
A setup for using several sets in parallel would be:
|
||
|
||
@example
|
||
#+TODO: TODO | DONE
|
||
#+TODO: REPORT BUG KNOWNCAUSE | FIXED
|
||
#+TODO: | CANCELED
|

@end example
|

||
@cindex completion, of option keywords
|
||
@kindex M-@key{TAB}
|
||
@noindent To make sure you are using the correct keyword, type
|
||
@samp{#+} into the buffer and then use @kbd{M-@key{TAB}} completion.
|
||
|
||
@cindex DONE, final TODO keyword
|
||
Remember that the keywords after the vertical bar (or the last keyword
|
||
if no bar is there) must always mean that the item is DONE (although you
|
||
may use a different word). After changing one of these lines, use
|
||
@kbd{C-c C-c} with the cursor still in the line to make the changes
|
||
known to Org mode@footnote{Org mode parses these lines only when
|
||
Org mode is activated after visiting a file. @kbd{C-c C-c} with the
|
||
cursor in a line starting with @samp{#+} is simply restarting Org mode
|
||
for the current buffer.}.

|

Org mode highlights TODO keywords with special faces: @code{org-todo}
|
||
for keywords indicating that an item still has to be acted upon, and
|
||
@code{org-done} for keywords indicating that an item is finished. If
|
||
you are using more than 2 different states, you might want to use
|
||
special faces for some of them. This can be done using the variable
|
||
@code{org-todo-keyword-faces}. For example:
|
||
|
||
@lisp
|
||
@group
|
||
(setq org-todo-keyword-faces
|
||
'(("TODO" . org-warning) ("STARTED" . "yellow")
|
||
("CANCELED" . (:foreground "blue" :weight bold))))
|
||
@end group
|
||
@end lisp
|
||
|
||
While using a list with face properties as shown for CANCELED @emph{should}
|
||
work, this does not always seem to be the case. If necessary, define a
|
||
special face and use that. A string is interpreted as a color. The variable
|

@code{org-faces-easy-properties} determines if that color is interpreted as a
|
||
foreground or a background color.

|
||
The structure of Org files (hierarchy and lists) makes it easy to define TODO
|
||
dependencies. Usually, a parent TODO task should not be marked DONE until
|
||
all subtasks (defined as children tasks) are marked as DONE. And sometimes
|
||
there is a logical sequence to a number of (sub)tasks, so that one task
|
||
cannot be acted upon before all siblings above it are done. If you customize
|
||
the variable @code{org-enforce-todo-dependencies}, Org will block entries
|
||
from changing state to DONE while they have children that are not DONE.
|
||
Furthermore, if an entry has a property @code{ORDERED}, each of its children
|
||
will be blocked until all earlier siblings are marked DONE. Here is an
|
||
example:
|
||
|
||
@example
|
||
* TODO Blocked until (two) is done
|
||
** DONE one
|
||
** TODO two
|
||
|

|

@cindex property, ORDERED
|
||
Toggle the @code{ORDERED} property of the current entry. A property is used
|
||
for this behavior because this should be local to the current entry, not

inherited like a tag. However, if you would like to @i{track} the value of

this property with a tag for better visibility, customize the variable

@lisp

(setq org-log-done 'time)

|

@noindent
|
||
Then each time you turn an entry from a TODO (not-done) state into any
|
||
of the DONE states, a line @samp{CLOSED: [timestamp]} will be inserted
|
||
just after the headline. If you turn the entry back into a TODO item
|
||
through further state cycling, that line will be removed again. If you
|
||
want to record a note along with the timestamp, use@footnote{The
|
||
corresponding in-buffer setting is: @code{#+STARTUP: lognotedone}}
|

@lisp
|

(setq org-log-done 'note)

|

When TODO keywords are used as workflow states (@pxref{Workflow states}), you
|
||
might want to keep track of when a state change occurred and maybe take a
|
||
note about this change. You can either record just a timestamp, or a
|
||
time-stamped note for a change. These records will be inserted after the
|
||
headline as an itemized list, newest first@footnote{See the variable
|
||
@code{org-log-states-order-reversed}}. When taking a lot of notes, you might
|
||
want to get the notes out of the way into a drawer (@pxref{Drawers}).
|
||
Customize the variable @code{org-log-into-drawer} to get this
|
||
behavior---the recommended drawer for this is called @code{LOGBOOK}. You can
|
||
also overrule the setting of this variable for a subtree by setting a
|
||
@code{LOG_INTO_DRAWER} property.
|
||
|
||
Since it is normally too much to record a note for every state, Org mode
|
||
expects configuration on a per-keyword basis for this. This is achieved by
|
||
adding special markers @samp{!} (for a timestamp) or @samp{@@} (for a note
|
||
with timestamp) in parentheses after each keyword. For example, with the

@vindex org-log-done
|
||
you not only define global TODO keywords and fast access keys, but also
|
||
request that a time is recorded when the entry is set to
|
||
DONE@footnote{It is possible that Org mode will record two timestamps
|
||
when you are using both @code{org-log-done} and state change logging.
|
||
However, it will never prompt for two notes---if you have configured
|
||
both, the state change recording note will take precedence and cancel
|
||
the @samp{Closing Note}.}, and that a note is recorded when switching to
|
||
WAIT or CANCELED. The setting for WAIT is even more special: the
|
||
@samp{!} after the slash means that in addition to the note taken when
|
||
entering the state, a timestamp should be recorded when @i{leaving} the
|
||
WAIT state, if and only if the @i{target} state does not configure
|
||
logging for entering it. So it has no effect when switching from WAIT
|
||
to DONE, because DONE is configured to record a timestamp only. But
|
||
when switching from WAIT back to TODO, the @samp{/!} in the WAIT
|
||
setting now triggers a timestamp even though TODO has no logging
|
||
configured.
|
||
|
||
You can use the exact same syntax for setting logging preferences local
|
||
to a buffer:
|
||
@example
|
||
#+TODO: TODO(t) WAIT(w@@/!) | DONE(d!) CANCELED(c@@)
|
||
@end example
|
||
|
||
@cindex property, LOGGING
|
||
In order to define logging settings that are local to a subtree or a
|
||
single item, define a LOGGING property in this entry. Any non-empty
|
||
LOGGING property resets all logging settings to nil. You may then turn
|
||
on logging for this specific tree using STARTUP keywords like
|
||
@code{lognotedone} or @code{logrepeat}, as well as adding state specific
|
||
settings like @code{TODO(!)}. For example
|
||
|
||
@example
|
||
* TODO Log each state with only a time
|
||
:PROPERTIES:
|
||
:LOGGING: TODO(!) WAIT(!) DONE(!) CANCELED(!)

@subsection Tracking your habits
|
||
@cindex habits
|
||
|
||
Org has the ability to track the consistency of a special category of TODOs,
|
||
called ``habits''. A habit has the following properties:
|
||
|
||
@enumerate
|
||
@item
|
||
You have enabled the @code{habits} module by customizing the variable
|
||
@code{org-modules}.
|
||
@item
|
||
The habit is a TODO item, with a TODO keyword representing an open state.
|
||
@item
|
||
The property @code{STYLE} is set to the value @code{habit}.
|
||
@item
|
||
The TODO has a scheduled date, usually with a @code{.+} style repeat
|
||
interval. A @code{++} style may be appropriate for habits with time
|
||
constraints, e.g., must be done on weekends, or a @code{+} style for an
|
||
unusual habit that can have a backlog, e.g., weekly reports.
|
||
@item
|
||
The TODO may also have minimum and maximum ranges specified by using the
|
||
syntax @samp{.+2d/3d}, which says that you want to do the task at least every
|
||
three days, but at most every two days.
|
||
@item
|
||
You must also have state logging for the @code{DONE} state enabled, in order
|
||
for historical data to be represented in the consistency graph. If it is not
|
||
enabled it is not an error, but the consistency graphs will be largely
|
||
meaningless.
|
||
@end enumerate
|
||
|
||
To give you an idea of what the above rules look like in action, here's an
|
||
actual habit with some history:
|
||
|
||
@example
|
||
** TODO Shave
|
||
SCHEDULED: <2009-10-17 Sat .+2d/4d>
|
||

||

|
||
:STYLE: habit
|
||
:LAST_REPEAT: [2009-10-19 Mon 00:36]
|
||
:END:
|
||
@end example
|
||
|
||
What this habit says is: I want to shave at most every 2 days (given by the
|
||
@code{SCHEDULED} date and repeat interval) and at least every 4 days. If
|
||
today is the 15th, then the habit first appears in the agenda on Oct 17,
|
||
after the minimum of 2 days has elapsed, and will appear overdue on Oct 19,
|
||
after four days have elapsed.
|
||
|
||
What's really useful about habits is that they are displayed along with a
|
||
consistency graph, to show how consistent you've been at getting that task
|
||
done in the past. This graph shows every day that the task was done over the
|
||
past three weeks, with colors for each day. The colors used are:
|
||
|
||
@table @code
|
||
@item Blue
|
||
If the task wasn't to be done yet on that day.
|
||
@item Green
|
||
If the task could have been done on that day.
|
||
@item Yellow
|
||
If the task was going to be overdue the next day.
|
||
@item Red
|
||
If the task was overdue on that day.
|
||
@end table
|
||
|
||
In addition to coloring each day, the day is also marked with an asterisk if
|
||
the task was actually done that day, and an exclamation mark to show where
|
||
the current day falls in the graph.
|
||
|
||
There are several configuration variables that can be used to change the way
|
||
habits are displayed in the agenda.
|
||
|
||
@table @code
|
||
@item org-habit-graph-column
|
||
The buffer column at which the consistency graph should be drawn. This will
|
||
overwrite any text in that column, so it is a good idea to keep your habits'
|
||
titles brief and to the point.
|
||
@item org-habit-preceding-days
|
||
The amount of history, in days before today, to appear in consistency graphs.
|
||
@item org-habit-following-days
|
||
The number of days after today that will appear in consistency graphs.
|
||
@item org-habit-show-habits-only-for-today
|
||
If non-nil, only show habits in today's agenda view. This is set to true by
|
||
default.
|
||
@end table
|
||
|
||
Lastly, pressing @kbd{K} in the agenda buffer will cause habits to
|
||
temporarily be disabled and they won't appear at all. Press @kbd{K} again to
|
||
bring them back. They are also subject to tag filtering, if you have habits
|
||
which should only be done in certain contexts, for example.
|
||
|
||
@node Priorities, Breaking down tasks, Progress logging, TODO Items
|
||
@section Priorities
|
||
@cindex priorities
|
||
|
||
If you use Org mode extensively, you may end up with enough TODO items that
|
||
it starts to make sense to prioritize them. Prioritizing can be done by
|
||
placing a @emph{priority cookie} into the headline of a TODO item, like this
|
||
|
||
@example
|
||
*** TODO [#A] Write letter to Sam Fortune
|
||
@end example
|
||
|
||
@noindent
|
||
@vindex org-priority-faces
|
||
By default, Org mode supports three priorities: @samp{A}, @samp{B}, and
|
||
@samp{C}. @samp{A} is the highest priority. An entry without a cookie is
|
||
treated just like priority @samp{B}. Priorities make a difference only for
|
||
sorting in the agenda (@pxref{Weekly/daily agenda}); outside the agenda, they
|
||
have no inherent meaning to Org mode. The cookies can be highlighted with
|
||
special faces by customizing the variable @code{org-priority-faces}.
|
||
|
||
Priorities can be attached to any outline node; they do not need to be TODO
|
||
items.
|
||
|
||
@table @kbd
|
||
@item @kbd{C-c ,}
|
||
@kindex @kbd{C-c ,}
|
||
@findex org-priority
|
||
Set the priority of the current headline (@command{org-priority}). The
|
||
command prompts for a priority character @samp{A}, @samp{B} or @samp{C}.
|
||
When you press @key{SPC} instead, the priority cookie is removed from the
|
||
headline. The priorities can also be changed ``remotely'' from the timeline
|
||
and agenda buffer with the @kbd{,} command (@pxref{Agenda commands}).
|
||
@c
|
||
@orgcmdkkcc{S-@key{up},S-@key{down},org-priority-up,org-priority-down}
|
||
@vindex org-priority-start-cycle-with-default
|
||
Increase/decrease priority of current headline@footnote{See also the option
|
||
@code{org-priority-start-cycle-with-default}.}. Note that these keys are
|
||
also used to modify timestamps (@pxref{Creating timestamps}). See also
|
||
@ref{Conflicts}, for a discussion of the interaction with
|
||
@code{shift-selection-mode}.
|
||
@end table
|
||
|
||
@vindex org-highest-priority
|
||
@vindex org-lowest-priority
|
||
@vindex org-default-priority
|
||
You can change the range of allowed priorities by setting the variables
|
||
@code{org-highest-priority}, @code{org-lowest-priority}, and
|
||
@code{org-default-priority}. For an individual buffer, you may set
|
||
these values (highest, lowest, default) like this (please make sure that
|
||
the highest priority is earlier in the alphabet than the lowest
|
||
priority):
|
||
|
||
@cindex #+PRIORITIES
|
||
@example
|
||
#+PRIORITIES: A C B

@node Breaking down tasks, Checkboxes, Priorities, TODO Items

@section Breaking tasks down into subtasks
|
||
@cindex tasks, breaking down
|
||
@cindex statistics, for TODO items
|
||
|
||
@vindex org-agenda-todo-list-sublevels
|
||
It is often advisable to break down large tasks into smaller, manageable
|
||
subtasks. You can do this by creating an outline tree below a TODO item,
|
||
with detailed subtasks on the tree@footnote{To keep subtasks out of the
|
||
global TODO list, see the @code{org-agenda-todo-list-sublevels}.}. To keep
|
||
the overview over the fraction of subtasks that are already completed, insert
|
||
either @samp{[/]} or @samp{[%]} anywhere in the headline. These cookies will
|
||
be updated each time the TODO status of a child changes, or when pressing
|
||
@kbd{C-c C-c} on the cookie. For example:
|
||
|
||
@example
|
||
* Organize Party [33%]
|
||
** TODO Call people [1/2]
|
||
*** TODO Peter
|
||
*** DONE Sarah
|
||
** TODO Buy food
|
||
** DONE Talk to neighbor
|
||
@end example
|
||
|
||
@cindex property, COOKIE_DATA
|
||
If a heading has both checkboxes and TODO children below it, the meaning of
|
||
the statistics cookie become ambiguous. Set the property
|
||
@code{COOKIE_DATA} to either @samp{checkbox} or @samp{todo} to resolve
|
||
this issue.
|
||
|
||
@vindex org-hierarchical-todo-statistics
|
||
If you would like to have the statistics cookie count any TODO entries in the
|
||
subtree (not just direct children), configure the variable
|
||
@code{org-hierarchical-todo-statistics}. To do this for a single subtree,
|
||
include the word @samp{recursive} into the value of the @code{COOKIE_DATA}
|
||
property.
|
||
|
||
@example
|
||
* Parent capturing statistics [2/20]
|
||
:PROPERTIES:
|
||
:COOKIE_DATA: todo recursive
|
||
:END:
|
||
@end example
|
||
|
||
If you would like a TODO entry to automatically change to DONE
|
||
when all children are done, you can use the following setup:
|
||
|
||
@example
|
||
(defun org-summary-todo (n-done n-not-done)
|
||
"Switch entry to DONE when all subentries are done, to TODO otherwise."
|
||
(let (org-log-done org-log-states) ; turn off logging
|
||
(org-todo (if (= n-not-done 0) "DONE" "TODO"))))
|
||
|
||
(add-hook 'org-after-todo-statistics-hook 'org-summary-todo)
|
||
@end example
|
||
|
||
|
||
Another possibility is the use of checkboxes to identify (a hierarchy of) a
|
||
large number of subtasks (@pxref{Checkboxes}).
|
||
|
||
|
||
@node Checkboxes, , Breaking down tasks, TODO Items
|
||
@section Checkboxes
|
||
@cindex checkboxes
|
||
|
||
@vindex org-list-automatic-rules
|
||
Every item in a plain list@footnote{With the exception of description
|
||
lists. But you can allow it by modifying @code{org-list-automatic-rules}
|
||
accordingly.} (@pxref{Plain lists}) can be made into a checkbox by starting
|
||
it with the string @samp{[ ]}. This feature is similar to TODO items
|
||
(@pxref{TODO Items}), but is more lightweight. Checkboxes are not included
|
||
into the global TODO list, so they are often great to split a task into a
|
||
number of simple steps. Or you can use them in a shopping list. To toggle a
|
||
checkbox, use @kbd{C-c C-c}, or use the mouse (thanks to Piotr Zielinski's
|
||
@file{org-mouse.el}).
|
||
|
||
Here is an example of a checkbox list.
|
||
|
||
@example
|
||
* TODO Organize party [2/4]
|
||
- [-] call people [1/3]
|
||
- [ ] Peter
|
||
- [X] Sarah
|
||
- [ ] Sam
|
||
- [X] order food
|
||
- [ ] think about what music to play
|
||
- [X] talk to the neighbors
|
||
@end example
|
||
|
||
Checkboxes work hierarchically, so if a checkbox item has children that
|
||
are checkboxes, toggling one of the children checkboxes will make the
|
||
parent checkbox reflect if none, some, or all of the children are
|
||
checked.
|
||
|
||
@cindex statistics, for checkboxes
|
||
@cindex checkbox statistics
|
||
@cindex property, COOKIE_DATA
|
||
@vindex org-hierarchical-checkbox-statistics
|
||
The @samp{[2/4]} and @samp{[1/3]} in the first and second line are cookies
|
||
indicating how many checkboxes present in this entry have been checked off,
|
||
and the total number of checkboxes present. This can give you an idea on how
|
||
many checkboxes remain, even without opening a folded entry. The cookies can
|
||
be placed into a headline or into (the first line of) a plain list item.
|
||
Each cookie covers checkboxes of direct children structurally below the
|
||
headline/item on which the cookie appears@footnote{Set the variable
|
||
@code{org-hierarchical-checkbox-statistics} if you want such cookies to
|
||
count all checkboxes below the cookie, not just those belonging to direct
|
||
children.}. You have to insert the cookie yourself by typing either
|
||
@samp{[/]} or @samp{[%]}. With @samp{[/]} you get an @samp{n out of m}
|
||
result, as in the examples above. With @samp{[%]} you get information about
|
||
the percentage of checkboxes checked (in the above example, this would be
|
||
@samp{[50%]} and @samp{[33%]}, respectively). In a headline, a cookie can
|
||
count either checkboxes below the heading or TODO states of children, and it
|
||
will display whatever was changed last. Set the property @code{COOKIE_DATA}
|
||
to either @samp{checkbox} or @samp{todo} to resolve this issue.
|
||
|
||
@cindex blocking, of checkboxes
|
||
@cindex checkbox blocking
|
||
@cindex property, ORDERED
|
||
If the current outline node has an @code{ORDERED} property, checkboxes must
|
||
be checked off in sequence, and an error will be thrown if you try to check
|
||
off a box while there are unchecked boxes above it.
|
||
|
||
@noindent The following commands work with checkboxes:
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-c,org-toggle-checkbox}
|
||
Toggle checkbox status or (with prefix arg) checkbox presence at point.
|
||
With a single prefix argument, add an empty checkbox or remove the current
|
||
one@footnote{`C-u C-c C-c' on the @emph{first} item of a list with no checkbox
|
||
will add checkboxes to the rest of the list.}. With a double prefix argument, set it to @samp{[-]}, which is
|
||
considered to be an intermediate state.
|
||
@orgcmd{C-c C-x C-b,org-toggle-checkbox}
|
||
Toggle checkbox status or (with prefix arg) checkbox presence at point. With
|
||
double prefix argument, set it to @samp{[-]}, which is considered to be an
|
||
intermediate state.
|
||
@itemize @minus
|
||
@item
|
||
If there is an active region, toggle the first checkbox in the region
|
||
and set all remaining boxes to the same status as the first. With a prefix
|
||
arg, add or remove the checkbox for all items in the region.
|
||
@item
|
||
If the cursor is in a headline, toggle checkboxes in the region between
|
||
this headline and the next (so @emph{not} the entire subtree).
|
||
@item
|
||
If there is no active region, just toggle the checkbox at point.
|
||
@end itemize
|
||
@orgcmd{M-S-@key{RET},org-insert-todo-heading}
|
||
Insert a new item with a checkbox. This works only if the cursor is already
|
||
in a plain list item (@pxref{Plain lists}).
|
||
@orgcmd{C-c C-x o,org-toggle-ordered-property}
|
||
@vindex org-track-ordered-property-with-tag
|
||
@cindex property, ORDERED
|
||
Toggle the @code{ORDERED} property of the entry, to toggle if checkboxes must
|
||
be checked off in sequence. A property is used for this behavior because
|
||
this should be local to the current entry, not inherited like a tag.
|
||
However, if you would like to @i{track} the value of this property with a tag
|
||
for better visibility, customize the variable
|
||
@code{org-track-ordered-property-with-tag}.
|
||
@orgcmd{C-c #,org-update-statistics-cookies}
|
||
Update the statistics cookie in the current outline entry. When called with
|
||
a @kbd{C-u} prefix, update the entire file. Checkbox statistic cookies are
|
||
updated automatically if you toggle checkboxes with @kbd{C-c C-c} and make
|
||
new ones with @kbd{M-S-@key{RET}}. TODO statistics cookies update when
|
||
changing TODO states. If you delete boxes/entries or add/change them by
|
||
hand, use this command to get things back into sync.

|
||
|
||
An excellent way to implement labels and contexts for cross-correlating
|
||
information is to assign @i{tags} to headlines. Org mode has extensive
|
||
support for tags.
|
||
|
||
@vindex org-tag-faces
|
||
Every headline can contain a list of tags; they occur at the end of the
|
||
headline. Tags are normal words containing letters, numbers, @samp{_}, and
|
||
@samp{@@}. Tags must be preceded and followed by a single colon, e.g.,
|
||
@samp{:work:}. Several tags can be specified, as in @samp{:work:urgent:}.
|
||
Tags will by default be in bold face with the same color as the headline.
|
||
You may specify special faces for specific tags using the variable
|
||
@code{org-tag-faces}, in much the same way as you can for TODO keywords
|
||
(@pxref{Faces for TODO keywords}).

@i{Tags} make use of the hierarchical structure of outline trees. If a

@noindent
|
||
the final heading will have the tags @samp{:work:}, @samp{:boss:},
|
||
@samp{:notes:}, and @samp{:action:} even though the final heading is not
|
||
explicitly marked with those tags. You can also set tags that all entries in
|
||
a file should inherit just as if these tags were defined in a hypothetical
|
||
level zero that surrounds the entire file. Use a line like this@footnote{As
|
||
with all these in-buffer settings, pressing @kbd{C-c C-c} activates any
|
||
changes in the line.}:
|
||
|

@noindent
|

@vindex org-use-tag-inheritance
|
||
@vindex org-tags-exclude-from-inheritance
|

To limit tag inheritance to specific tags, or to turn it off entirely, use

the variables @code{org-use-tag-inheritance} and
|
||
@code{org-tags-exclude-from-inheritance}.
|
||
|
||
@vindex org-tags-match-list-sublevels
|
||
When a headline matches during a tags search while tag inheritance is turned
|
||
on, all the sublevels in the same tree will (for a simple match form) match
|
||
as well@footnote{This is only true if the search does not involve more
|
||
complex tests including properties (@pxref{Property searches}).}. The list
|
||
of matches may then become very long. If you only want to see the first tags
|
||
match in a subtree, configure the variable

Tags can simply be typed into the buffer at the end of a headline.
|
||
After a colon, @kbd{M-@key{TAB}} offers completion on tags. There is
|
||
also a special command for inserting tags:
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-q,org-set-tags-command}
|
||
@cindex completion, of tags
|
||
@vindex org-tags-column
|
||
Enter new tags for the current headline. Org mode will either offer
|
||
completion or a special single-key interface for setting tags, see
|
||
below. After pressing @key{RET}, the tags will be inserted and aligned
|
||
to @code{org-tags-column}. When called with a @kbd{C-u} prefix, all
|
||
tags in the current buffer will be aligned to that column, just to make
|
||
things look nice. TAGS are automatically realigned after promotion,
|
||
demotion, and TODO state changes (@pxref{TODO basics}).
|
||
@orgcmd{C-c C-c,org-set-tags-command}
|
||
When the cursor is in a headline, this does the same as @kbd{C-c C-q}.
|
||
@end table
|
||
|
||
@vindex org-tag-alist
|
||
Org supports tag insertion based on a @emph{list of tags}. By
|
||
default this list is constructed dynamically, containing all tags
|
||
currently used in the buffer. You may also globally specify a hard list
|
||
of tags with the variable @code{org-tag-alist}. Finally you can set
|
||
the default tags for a given file with lines like
|
||
|
||
@cindex #+TAGS
|
||
@example
|
||
#+TAGS: @@work @@home @@tennisclub
|
||
#+TAGS: laptop car pc sailboat
|
||
@end example
|
||
|
||
If you have globally defined your preferred set of tags using the
|
||
variable @code{org-tag-alist}, but would like to use a dynamic tag list
|
||
in a specific file, add an empty TAGS option line to that file:
|
||
|
||
@example
|
||
#+TAGS:
|
||
@end example
|
||
|
||
@vindex org-tag-persistent-alist
|
||
If you have a preferred set of tags that you would like to use in every file,
|
||
in addition to those defined on a per-file basis by TAGS option lines, then
|
||
you may specify a list of tags with the variable
|
||
@code{org-tag-persistent-alist}. You may turn this off on a per-file basis
|
||
by adding a STARTUP option line to that file:
|
||
|
||
@example
|
||
#+STARTUP: noptag
|
||
@end example
|
||
|
||
By default Org mode uses the standard minibuffer completion facilities for
|
||
entering tags. However, it also implements another, quicker, tag selection
|
||
method called @emph{fast tag selection}. This allows you to select and
|
||
deselect tags with just a single key press. For this to work well you should
|
||
assign unique letters to most of your commonly used tags. You can do this
|
||
globally by configuring the variable @code{org-tag-alist} in your
|
||
@file{.emacs} file. For example, you may find the need to tag many items in
|
||
different files with @samp{:@@home:}. In this case you can set something
|
||
like:
|
||
|
||
@lisp
|
||
(setq org-tag-alist '(("@@work" . ?w) ("@@home" . ?h) ("laptop" . ?l)))
|
||
@end lisp
|
||
|
||
@noindent If the tag is only relevant to the file you are working on, then you
|
||
can instead set the TAGS option line as:
|
||
|
||
@example
|
||
#+TAGS: @@work(w) @@home(h) @@tennisclub(t) laptop(l) pc(p)
|
||
@end example
|
||
|
||
@noindent The tags interface will show the available tags in a splash
|
||
window. If you want to start a new line after a specific tag, insert
|
||
@samp{\n} into the tag list
|
||
|
||
@example
|
||
#+TAGS: @@work(w) @@home(h) @@tennisclub(t) \n laptop(l) pc(p)
|
||
@end example
|
||
|
||
@noindent or write them in two lines:
|
||
|
||
@example
|
||
#+TAGS: @@work(w) @@home(h) @@tennisclub(t)
|
||
#+TAGS: laptop(l) pc(p)
|
||
@end example
|
||
|
||
@noindent
|
||
You can also group together tags that are mutually exclusive by using
|
||
braces, as in:
|
||
|
||
@example
|
||
#+TAGS: @{ @@work(w) @@home(h) @@tennisclub(t) @} laptop(l) pc(p)
|
||
@end example
|
||
|
||
@noindent you indicate that at most one of @samp{@@work}, @samp{@@home},
|
||
and @samp{@@tennisclub} should be selected. Multiple such groups are allowed.
|
||
|
||
@noindent Don't forget to press @kbd{C-c C-c} with the cursor in one of
|
||
these lines to activate any changes.
|
||
|
||
@noindent
|
||
To set these mutually exclusive groups in the variable @code{org-tags-alist},
|
||
you must use the dummy tags @code{:startgroup} and @code{:endgroup} instead
|
||
of the braces. Similarly, you can use @code{:newline} to indicate a line
|
||
break. The previous example would be set globally by the following
|
||
configuration:
|
||
|
||
@lisp
|
||
(setq org-tag-alist '((:startgroup . nil)
|
||
("@@work" . ?w) ("@@home" . ?h)
|
||
("@@tennisclub" . ?t)
|
||
(:endgroup . nil)
|
||
("laptop" . ?l) ("pc" . ?p)))
|
||
@end lisp
|
||
|
||
If at least one tag has a selection key then pressing @kbd{C-c C-c} will
|
||
automatically present you with a special interface, listing inherited tags,
|
||
the tags of the current headline, and a list of all valid tags with
|
||
corresponding keys@footnote{Keys will automatically be assigned to tags which
|
||
have no configured keys.}. In this interface, you can use the following
|
||
keys:
|
||
|
||
@table @kbd
|
||
@item a-z...
|
||
Pressing keys assigned to tags will add or remove them from the list of
|
||
tags in the current line. Selecting a tag in a group of mutually
|
||
exclusive tags will turn off any other tags from that group.
|
||
@kindex @key{TAB}
|
||
@item @key{TAB}
|
||
Enter a tag in the minibuffer, even if the tag is not in the predefined
|
||
list. You will be able to complete on all tags present in the buffer.
|
||
You can also add several tags: just separate them with a comma.
|
||
|
||
@kindex @key{SPC}
|
||
@item @key{SPC}
|
||
Clear all tags for this line.
|
||
@kindex @key{RET}
|
||
@item @key{RET}
|
||
Accept the modified set.
|
||
@item C-g
|
||
Abort without installing changes.
|
||
@item q
|
||
If @kbd{q} is not assigned to a tag, it aborts like @kbd{C-g}.
|
||
@item !
|
||
Turn off groups of mutually exclusive tags. Use this to (as an
|
||
exception) assign several tags from such a group.
|
||
@item C-c
|
||
Toggle auto-exit after the next change (see below).
|
||
If you are using expert mode, the first @kbd{C-c} will display the
|
||
selection window.
|
||
@end table
|
||
|
||
@noindent
|
||
This method lets you assign tags to a headline with very few keys. With
|
||
the above setup, you could clear the current tags and set @samp{@@home},
|
||
@samp{laptop} and @samp{pc} tags with just the following keys: @kbd{C-c
|
||
C-c @key{SPC} h l p @key{RET}}. Switching from @samp{@@home} to
|
||
@samp{@@work} would be done with @kbd{C-c C-c w @key{RET}} or
|
||
alternatively with @kbd{C-c C-c C-c w}. Adding the non-predefined tag
|
||
@samp{Sarah} could be done with @kbd{C-c C-c @key{TAB} S a r a h
|
||
@key{RET} @key{RET}}.
|
||
|
||
@vindex org-fast-tag-selection-single-key
|
||
If you find that most of the time you need only a single key press to
|
||
modify your list of tags, set the variable
|
||
@code{org-fast-tag-selection-single-key}. Then you no longer have to
|
||
press @key{RET} to exit fast tag selection---it will immediately exit
|
||
after the first change. If you then occasionally need more keys, press
|
||
@kbd{C-c} to turn off auto-exit for the current tag selection process
|
||
(in effect: start selection with @kbd{C-c C-c C-c} instead of @kbd{C-c
|
||
C-c}). If you set the variable to the value @code{expert}, the special
|
||
window is not even shown for single-key tag selection, it comes up only
|
||
when you press an extra @kbd{C-c}.

@cindex properties
|
||
|
||
A property is a key-value pair associated with an entry. Properties can be
|
||
set so they are associated with a single entry, with every entry in a tree,
|
||
or with every entry in an Org mode file.
|
||
|
||
There are two main applications for properties in Org mode. First,
|
||
properties are like tags, but with a value. Imagine maintaining a file where
|
||
you document bugs and plan releases for a piece of software. Instead of
|
||
using tags like @code{:release_1:}, @code{:release_2:}, you can use a
|
||
property, say @code{:Release:}, that in different subtrees has different
|
||
values, such as @code{1.0} or @code{2.0}. Second, you can use properties to
|
||
implement (very basic) database capabilities in an Org buffer. Imagine
|
||
keeping track of your music CDs, where properties could be things such as the
|
||
album, artist, date of release, number of tracks, and so on.
|
||
|
||
Properties can be conveniently edited and viewed in column view
|
||
(@pxref{Column view}).

@cindex drawer, for properties
|
||
|
||
Properties are key-value pairs. When they are associated with a single entry
|
||
or with a tree they need to be inserted into a special
|
||
drawer (@pxref{Drawers}) with the name @code{PROPERTIES}. Each property
|
||
is specified on a single line, with the key (surrounded by colons)
|
||
first, and the value after it. Here is an example:
|
||
|
||
@example
|
||
* CD collection
|
||
** Classic
|
||
*** Goldberg Variations
|
||
:PROPERTIES:
|
||
:Title: Goldberg Variations
|
||
:Composer: J.S. Bach
|
||
:Artist: Glen Gould
|
||
:Publisher: Deutsche Grammophon
|
||
:NDisks: 1
|
||
:END:
|
||
@end example
|
||
|
||
Depending on the value of @code{org-use-property-inheritance}, a property set
|
||
this way will either be associated with a single entry, or the sub-tree
|
||
defined by the entry, see @ref{Property inheritance}.
|
||
|
||
You may define the allowed values for a particular property @samp{:Xyz:}
|
||
by setting a property @samp{:Xyz_ALL:}. This special property is
|
||
@emph{inherited}, so if you set it in a level 1 entry, it will apply to
|
||
the entire tree. When allowed values are defined, setting the
|
||
corresponding property becomes easier and is less prone to typing
|
||
errors. For the example with the CD collection, we can predefine
|
||
publishers and the number of disks in a box like this:
|
||
|
||
@example
|
||
* CD collection
|
||
:PROPERTIES:
|
||
:NDisks_ALL: 1 2 3 4
|
||
:Publisher_ALL: "Deutsche Grammophon" Philips EMI
|
||
:END:
|
||
@end example
|
||
|
||
If you want to set properties that can be inherited by any entry in a
|
||
file, use a line like
|
||
@cindex property, _ALL
|
||
@cindex #+PROPERTY
|
||
@example
|
||
#+PROPERTY: NDisks_ALL 1 2 3 4
|
||
@end example
|
||
|
||
If you want to add to the value of an existing property, append a @code{+} to
|
||
the property name. The following results in the property @code{var} having
|
||
the value ``foo=1 bar=2''.
|
||
@cindex property, +
|
||
@example
|
||
#+PROPERTY: var foo=1
|
||
#+PROPERTY: var+ bar=2
|
||
@end example
|
||
|
||
It is also possible to add to the values of inherited properties. The
|
||
following results in the @code{genres} property having the value ``Classic
|
||
Baroque'' under the @code{Goldberg Variations} subtree.
|
||
@cindex property, +
|
||
@example
|
||
* CD collection
|

@item M-x org-insert-property-drawer
|
||
@findex org-insert-property-drawer
|

single property:
|
||
|
||
@table @kbd
|
||
@orgkey{C-c / p}
|
||
Create a sparse tree based on the value of a property. This first
|
||
prompts for the name of a property, and then for a value. A sparse tree
|
||
is created with all entries that define this property with the given
|
||
value. If you enclose the value in curly braces, it is interpreted as
|
||
a regular expression and matched against the property values.

The outline structure of Org mode documents lends itself to an
|
||
inheritance model of properties: if the parent in a tree has a certain
|
||
property, the children can inherit this property. Org mode does not
|
||
turn this on by default, because it can slow down property searches
|
||
significantly and is often not needed. However, if you find inheritance
|
||
useful, you can turn it on by setting the variable
|
||
@code{org-use-property-inheritance}. It may be set to @code{t} to make
|
||
all properties inherited from the parent, to a list of properties
|
||
that should be inherited, or to a regular expression that matches
|
||
inherited properties. If a property has the value @samp{nil}, this is
|
||
interpreted as an explicit undefine of the property, so that inheritance
|
||
search will stop at this value and return @code{nil}.
|
||
|
||
Org mode has a few properties for which inheritance is hard-coded, at
|
||
least for the special applications for which they are used:
|
||
|
||
@cindex property, COLUMNS
|
||
@table @code
|
||
@item COLUMNS
|
||
The @code{:COLUMNS:} property defines the format of column view

(@pxref{Column view}). It is inherited in the sense that the level

where a @code{:COLUMNS:} property is defined is used as the starting

subtree from where columns view is turned on.

|
||
|
||
A great way to view and edit properties in an outline tree is
|
||
@emph{column view}. In column view, each outline node is turned into a
|
||
table row. Columns in this table provide access to properties of the
|
||
entries. Org mode implements columns by overlaying a tabular structure
|
||
over the headline of each item. While the headlines have been turned
|
||
into a table row, you can still change the visibility of the outline
|
||
tree. For example, you get a compact table by switching to CONTENTS
|
||
view (@kbd{S-@key{TAB} S-@key{TAB}}, or simply @kbd{c} while column view
|
||
is active), but you can still open, read, and edit the entry below each
|
||
headline. Or, you can switch to column view after executing a sparse
|
||
tree command and in this way get a table only for the selected items.
|
||
Column view also works in agenda buffers (@pxref{Agenda Views}) where
|
||
queries have collected selected items, possibly from a number of files.

done by defining a column format line.

@subsubsection Scope of column definitions
|
||
|
||
To define a column format for an entire file, use a line like
|
||
|
||
@cindex #+COLUMNS
|
||
@example
|
||
#+COLUMNS: %25ITEM %TAGS %PRIORITY %TODO
|
||
@end example
|
||
|
||
To specify a format that only applies to a specific tree, add a
|
||
@code{:COLUMNS:} property to the top node of that tree, for example:
|
||
|
||
@example
|
||
** Top node for columns view
|
||
:PROPERTIES:
|
||
:COLUMNS: %25ITEM %TAGS %PRIORITY %TODO
|
||
:END:
|
||
@end example
|
||
|
||
If a @code{:COLUMNS:} property is present in an entry, it defines columns
|
||
for the entry itself, and for the entire subtree below it. Since the
|
||
column definition is part of the hierarchical structure of the document,
|
||
you can define columns on level 1 that are general enough for all
|
||
sublevels, and more specific columns further down, when you edit a
|
||
deeper part of the tree.
|
||
|
||
@node Column attributes, , Scope of column definitions, Defining columns
|
||
@subsubsection Column attributes
|
||
A column definition sets the attributes of a column. The general
|
||
definition looks like this:
|
||
|
||
@example
|
||
%[@var{width}]@var{property}[(@var{title})][@{@var{summary-type}@}]
|
||
@end example
|
||
|
||
@noindent
|
||
Except for the percent sign and the property name, all items are
|
||
optional. The individual parts have the following meaning:
|
||
|
||
@example
|
||
@var{width} @r{An integer specifying the width of the column in characters.}
|
||
@r{If omitted, the width will be determined automatically.}
|
||
@var{property} @r{The property that should be edited in this column.}
|
||
@r{Special properties representing meta data are allowed here}
|
||
@r{as well (@pxref{Special properties})}
|
||
@var{title} @r{The header text for the column. If omitted, the property}
|
||
@r{name is used.}
|
||
@{@var{summary-type}@} @r{The summary type. If specified, the column values for}
|
||
@r{parent nodes are computed from the children.}
|
||
@r{Supported summary types are:}
|
||
@{+@} @r{Sum numbers in this column.}
|
||
@{+;%.1f@} @r{Like @samp{+}, but format result with @samp{%.1f}.}
|
||
@{$@} @r{Currency, short for @samp{+;%.2f}.}
|
||
@{:@} @r{Sum times, HH:MM, plain numbers are hours.}
|
||
@{X@} @r{Checkbox status, @samp{[X]} if all children are @samp{[X]}.}
|
||
@{X/@} @r{Checkbox status, @samp{[n/m]}.}
|
||
@{X%@} @r{Checkbox status, @samp{[n%]}.}
|
||
@{min@} @r{Smallest number in column.}
|
||
@{max@} @r{Largest number.}
|
||
@{mean@} @r{Arithmetic mean of numbers.}
|
||
@{:min@} @r{Smallest time value in column.}
|
||
@{:max@} @r{Largest time value.}
|
||
@{:mean@} @r{Arithmetic mean of time values.}
|
||
@{@@min@} @r{Minimum age (in days/hours/mins/seconds).}
|
||
@{@@max@} @r{Maximum age (in days/hours/mins/seconds).}
|
||
@{@@mean@} @r{Arithmetic mean of ages (in days/hours/mins/seconds).}
|
||
@{est+@} @r{Add low-high estimates.}
|
||
@end example
|
||
|
||
@noindent
|
||
Be aware that you can only have one summary type for any property you
|
||
include. Subsequent columns referencing the same property will all display the
|
||
same summary information.
|
||
|
||
The @code{est+} summary type requires further explanation. It is used for
|
||
combining estimates, expressed as low-high ranges. For example, instead
|
||
of estimating a particular task will take 5 days, you might estimate it as
|
||
5-6 days if you're fairly confident you know how much work is required, or
|
||
1-10 days if you don't really know what needs to be done. Both ranges
|
||
average at 5.5 days, but the first represents a more predictable delivery.
|
||
|
||
When combining a set of such estimates, simply adding the lows and highs
|
||
produces an unrealistically wide result. Instead, @code{est+} adds the
|
||
statistical mean and variance of the sub-tasks, generating a final estimate
|
||
from the sum. For example, suppose you had ten tasks, each of which was
|
||
estimated at 0.5 to 2 days of work. Straight addition produces an estimate
|
||
of 5 to 20 days, representing what to expect if everything goes either
|
||
extremely well or extremely poorly. In contrast, @code{est+} estimates the
|
||
full job more realistically, at 10-15 days.
|
||
|
||
Here is an example for a complete columns definition, along with allowed
|
||
values.
|
||
|
||
@example
|
||
:COLUMNS: %25ITEM %9Approved(Approved?)@{X@} %Owner %11Status \@footnote{Please note that the COLUMNS definition must be on a single line---it is wrapped here only because of formatting constraints.}
|
||
%10Time_Estimate@{:@} %CLOCKSUM
|
||
:Owner_ALL: Tammy Mark Karl Lisa Don
|
||
:Status_ALL: "In progress" "Not started yet" "Finished" ""
|
||
:Approved_ALL: "[ ]" "[X]"
|
||
@end example
|
||
|
||
@noindent
|
||
The first column, @samp{%25ITEM}, means the first 25 characters of the
|
||
item itself, i.e.@: of the headline. You probably always should start the
|
||
column definition with the @samp{ITEM} specifier. The other specifiers
|
||
create columns @samp{Owner} with a list of names as allowed values, for
|
||
@samp{Status} with four different possible values, and for a checkbox
|
||
field @samp{Approved}. When no width is given after the @samp{%}
|
||
character, the column will be exactly as wide as it needs to be in order
|
||
to fully display all values. The @samp{Approved} column does have a
|
||
modified title (@samp{Approved?}, with a question mark). Summaries will
|
||
be created for the @samp{Time_Estimate} column by adding time duration
|
||
expressions like HH:MM, and for the @samp{Approved} column, by providing
|
||
an @samp{[X]} status if all children have been checked. The
|
||
@samp{CLOCKSUM} column is special, it lists the sum of CLOCK intervals
|
||
in the subtree.

|
||
Turn on column view. If the cursor is before the first headline in the file,
|
||
column view is turned on for the entire file, using the @code{#+COLUMNS}
|
||
definition. If the cursor is somewhere inside the outline, this command
|
||
searches the hierarchy, up from point, for a @code{:COLUMNS:} property that
|
||
defines a format. When one is found, the column view table is established
|
||
for the tree starting at the entry that contains the @code{:COLUMNS:}
|
||
property. If no such property is found, the format is taken from the
|
||
@code{#+COLUMNS} line or from the variable @code{org-columns-default-format},
|
||
and column view is established for the current entry and its subtree.
|
||
@orgcmd{r,org-columns-redo}

have to have specified allowed values for a property.
|

property. For example, when editing a TAGS property, the tag completion
|
||
or fast selection interface will pop up.

@subsection Capturing column view
|
||
|
||
Since column view is just an overlay over a buffer, it cannot be
|
||
exported or printed directly. If you want to capture a column view, use
|
||
a @code{columnview} dynamic block (@pxref{Dynamic blocks}). The frame
|
||
of this block looks like this:
|
||
|
||
@cindex #+BEGIN, columnview
|
||
@example
|
||
* The column view
|
||
#+BEGIN: columnview :hlines 1 :id "label"
|
||
|
||
#+END:
|
||
@end example
|
||
|
||
@noindent This dynamic block has the following parameters:
|
||
|
||
@table @code
|
||
@item :id
|
||
This is the most important parameter. Column view is a feature that is
|
||
often localized to a certain (sub)tree, and the capture block might be
|
||
at a different location in the file. To identify the tree whose view to
|
||
capture, you can use 4 values:
|
||
@cindex property, ID
|
||
@example
|
||
local @r{use the tree in which the capture block is located}
|
||
global @r{make a global view, including all headings in the file}
|
||
"file:@var{path-to-file}"
|
||
@r{run column view at the top of this file}
|
||
"@var{ID}" @r{call column view in the tree that has an @code{:ID:}}
|
||
@r{property with the value @i{label}. You can use}
|
||
@r{@kbd{M-x org-id-copy} to create a globally unique ID for}
|
||
@r{the current entry and copy it to the kill-ring.}
|
||
@end example
|
||
@item :hlines
|
||
When @code{t}, insert an hline after every line. When a number @var{N}, insert
|
||
an hline before each headline with level @code{<= @var{N}}.
|
||
@item :vlines
|
||
When set to @code{t}, force column groups to get vertical lines.
|
||
@item :maxlevel
|
||
When set to a number, don't capture entries below this level.
|
||
@item :skip-empty-rows
|
||
When set to @code{t}, skip rows where the only non-empty specifier of the
|
||
column view is @code{ITEM}.
|
||
|
||
@end table
|
||
|
||
@noindent
|
||
The following commands insert or update the dynamic block:
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-x i,org-insert-columns-dblock}
|
||
Insert a dynamic block capturing a column view. You will be prompted
|
||
for the scope or ID of the view.
|
||
@orgcmdkkc{C-c C-c,C-c C-x C-u,org-dblock-update}
|
||
Update dynamic block at point. The cursor needs to be in the
|
||
@code{#+BEGIN} line of the dynamic block.
|
||
@orgcmd{C-u C-c C-x C-u,org-update-all-dblocks}
|
||
Update all dynamic blocks (@pxref{Dynamic blocks}). This is useful if
|
||
you have several clock table blocks, column-capturing blocks or other dynamic
|
||
blocks in a buffer.
|
||
@end table
|
||
|
||
You can add formulas to the column view table and you may add plotting
|
||
instructions in front of the table---these will survive an update of the
|
||
block. If there is a @code{#+TBLFM:} after the table, the table will
|
||
actually be recalculated automatically after an update.
|
||
|
||
An alternative way to capture and process property values into a table is
|
||
provided by Eric Schulte's @file{org-collector.el} which is a contributed
|
||
package@footnote{Contributed packages are not part of Emacs, but are
|
||
distributed with the main distribution of Org (visit
|
||
@uref{http://orgmode.org}).}. It provides a general API to collect
|
||
properties from entries in a certain scope, and arbitrary Lisp expressions to
|
||
process these values before inserting them into a table or a dynamic block.

A timestamp is a specification of a date (possibly with a time or a range of
|
||
times) in a special format, either @samp{<2003-09-16 Tue>}@footnote{In this
|
||
simplest form, the day name is optional when you type the date yourself.
|
||
However, any dates inserted or modified by Org will add that day name, for
|
||
reading convenience.} or @samp{<2003-09-16 Tue 09:39>} or @samp{<2003-09-16
|
||
Tue 12:00-12:30>}@footnote{This is inspired by the standard ISO 8601
|
||
date/time format. To use an alternative format, see @ref{Custom time
|
||
format}.}. A timestamp can appear anywhere in the headline or body of an Org
|
||
tree entry. Its presence causes entries to be shown on specific dates in the
|
||
agenda (@pxref{Weekly/daily agenda}). We distinguish:
|
||
|
||
@table @var
|
||
@item Plain timestamp; Event; Appointment
|
||
@cindex timestamp
|
||
@cindex appointment
|
||
A simple timestamp just assigns a date/time to an item. This is just
|
||
like writing down an appointment or event in a paper agenda. In the
|
||
timeline and agenda displays, the headline of an entry associated with a
|
||
plain timestamp will be shown exactly on that date.
|
||
|
||
@example
|
||
* Meet Peter at the movies <2006-11-01 Wed 19:15>
|
||
* Discussion on climate change <2006-11-02 Thu 20:00-22:00>

||
@end example
|

@item Timestamp with repeater interval

@cindex timestamp, with repeater interval
|
||
A timestamp may contain a @emph{repeater interval}, indicating that it
|
||
applies not only on the given date, but again and again after a certain
|
||
interval of N days (d), weeks (w), months (m), or years (y). The
|
||
following will show up in the agenda every Wednesday:
|
||
|
||
@example
|
||
* Pick up Sam at school <2007-05-16 Wed 12:30 +1w>
|
||
@end example
|
||
|
||
@item Diary-style sexp entries
|
||
For more complex date specifications, Org mode supports using the special
|
||
sexp diary entries implemented in the Emacs calendar/diary
|
||
package@footnote{When working with the standard diary sexp functions, you
|
||
need to be very careful with the order of the arguments. That order depend
|
||
evilly on the variable @code{calendar-date-style} (or, for older Emacs
|
||
versions, @code{european-calendar-style}). For example, to specify a date
|
||
December 12, 2005, the call might look like @code{(diary-date 12 1 2005)} or
|
||
@code{(diary-date 1 12 2005)} or @code{(diary-date 2005 12 1)}, depending on
|
||
the settings. This has been the source of much confusion. Org mode users
|
||
can resort to special versions of these functions like @code{org-date} or
|
||
@code{org-anniversary}. These work just like the corresponding @code{diary-}
|
||
functions, but with stable ISO order of arguments (year, month, day) wherever
|
||
applicable, independent of the value of @code{calendar-date-style}.}. For
|
||
example with optional time
|
||
|
||
@example
|
||
* 22:00-23:00 The nerd meeting on every 2nd Thursday of the month
|

||
will be shown on the first and last day of the range, and on any dates
|
||
that are displayed and fall in the range. Here is an example:
|
||
|
||

||
@emph{not} trigger an entry to show up in the agenda.

@vindex org-read-date-prefer-future
|
||
When Org mode prompts for a date/time, the default is shown in default
|
||
date/time format, and the prompt therefore seems to ask for a specific
|
||
format. But it will in fact accept any string containing some date and/or
|
||
time information, and it is really smart about interpreting your input. You
|
||
can, for example, use @kbd{C-y} to paste a (possibly multi-line) string
|
||
copied from an email message. Org mode will find whatever information is in
|
||
there and derive anything you have not specified from the @emph{default date
|
||
and time}. The default is usually the current date and time, but when
|
||
modifying an existing timestamp, or when entering the second stamp of a
|
||
range, it is taken from the stamp in the buffer. When filling in
|
||
information, Org mode assumes that most of the time you will want to enter a
|
||
date in the future: if you omit the month/year and the given day/month is
|
||
@i{before} today, it will assume that you mean a future date@footnote{See the
|
||
variable @code{org-read-date-prefer-future}. You may set that variable to
|
||
the symbol @code{time} to even make a time before now shift the date to
|
||
tomorrow.}. If the date has been automatically shifted into the future, the
|
||
time prompt will show this with @samp{(=>F).}
|
||
|
||
For example, let's assume that today is @b{June 13, 2006}. Here is how
|
||
various inputs will be interpreted, the items filled in by Org mode are
|
||
in @b{bold}.
|
||
|
||
@example
|
||
3-2-5 @result{} 2003-02-05
|
||
2/5/3 @result{} 2003-02-05
|
||
14 @result{} @b{2006}-@b{06}-14
|
||
12 @result{} @b{2006}-@b{07}-12
|
||
2/5 @result{} @b{2007}-02-05
|
||
Fri @result{} nearest Friday (default date or later)
|
||
sep 15 @result{} @b{2006}-09-15
|
||
feb 15 @result{} @b{2007}-02-15
|
||
sep 12 9 @result{} 2009-09-12
|
||
12:45 @result{} @b{2006}-@b{06}-@b{13} 12:45
|
||
22 sept 0:34 @result{} @b{2006}-09-22 0:34
|
||
w4 @result{} ISO week for of the current year @b{2006}
|
||
2012 w4 fri @result{} Friday of ISO week 4 in 2012
|
||
2012-w04-5 @result{} Same as above
|
||
@end example
|
||
|
||
Furthermore you can specify a relative date by giving, as the
|
||
@emph{first} thing in the input: a plus/minus sign, a number and a
|
||
letter ([dwmy]) to indicate change in days, weeks, months, or years. With a
|
||
single plus or minus, the date is always relative to today. With a
|
||
double plus or minus, it is relative to the default date. If instead of
|
||
a single letter, you use the abbreviation of day name, the date will be
|
||
the Nth such day, e.g.@:
|
||
|
||
@example
|
||
+0 @result{} today
|
||
. @result{} today
|
||
+4d @result{} four days from today
|
||
+4 @result{} same as above
|
||
+2w @result{} two weeks from today
|
||
++5 @result{} five days from default date
|
||
+2tue @result{} second Tuesday from now.
|
||
@end example

@vindex parse-time-months

|

The function understands English month and weekday abbreviations. If
|
||
you want to use unabbreviated names and/or other languages, configure
|
||
the variables @code{parse-time-months} and @code{parse-time-weekdays}.
|
||
|
||
@vindex org-read-date-force-compatible-dates
|
||
Not all dates can be represented in a given Emacs implementation. By default
|
||
Org mode forces dates into the compatibility range 1970--2037 which works on
|
||
all Emacs implementations. If you want to use dates outside of this range,
|
||
read the docstring of the variable
|
||
@code{org-read-date-force-compatible-dates}.
|
||
|
||
You can specify a time range by giving start and end times or by giving a
|
||
start time and a duration (in HH:MM format). Use one or two dash(es) as the
|
||
separator in the former case and use '+' as the separator in the latter
|
||
case, e.g.@:
|
||
|
||
@example
|
||
11am-1:15pm @result{} 11:00-13:15

|

@end example
|

@cindex calendar, for selecting date

Parallel to the minibuffer prompt, a calendar is popped up@footnote{If

Org mode uses the standard ISO notation for dates and times as it is

defined in ISO 8601. If you cannot get used to this and require another
|
||
representation of date and time to keep you happy, you can get it by

customizing the variables @code{org-display-custom-times} and

@code{org-time-stamp-custom-formats}.

|

@end table
|

|

@noindent
|
||
Org mode needs the default format for scanning, so the custom date/time
|
||
format does not @emph{replace} the default format---instead it is put
|
||
@emph{over} the default format using text properties. This has the
|
||
following consequences:
|
||
@itemize @bullet
|
||
@item
|
||
You cannot place the cursor onto a timestamp anymore, only before or
|
||
after.
|
||
@item
|
||
The @kbd{S-@key{up}/@key{down}} keys can no longer be used to adjust
|
||
each component of a timestamp. If the cursor is at the beginning of
|
||
the stamp, @kbd{S-@key{up}/@key{down}} will change the stamp by one day,
|
||
just like @kbd{S-@key{left}/@key{right}}. At the end of the stamp, the
|
||
time will be changed by one minute.
|
||
@item
|
||
If the timestamp contains a range of clock times or a repeater, these
|
||
will not be overlaid, but remain in the buffer as they were.
|
||
@item
|
||
When you delete a timestamp character-by-character, it will only
|
||
disappear from the buffer after @emph{all} (invisible) characters
|
||
belonging to the ISO timestamp have been removed.
|
||
@item
|
||
If the custom timestamp format is longer than the default and you are
|
||
using dates in tables, table alignment will be messed up. If the custom
|
||
format is shorter, things do work as expected.

@noindent
|

@b{Important:} Scheduling an item in Org mode should @i{not} be
|
||
understood in the same way that we understand @i{scheduling a meeting}.
|
||
Setting a date for a meeting is just a simple appointment, you should
|
||
mark this entry with a simple plain timestamp, to get this item shown
|
||
on the date where it applies. This is a frequent misunderstanding by
|
||
Org users. In Org mode, @i{scheduling} means setting a date when you
|
||
want to start working on an action item.
|
||
@end table
|
||
|
||
You may use timestamps with repeaters in scheduling and deadline
|
||
entries. Org mode will issue early and late warnings based on the
|
||
assumption that the timestamp represents the @i{nearest instance} of
|
||
the repeater. However, the use of diary sexp entries like
|
||
@c
|
||
@code{<%%(org-float t 42)>}
|
||
@c
|
||
in scheduling and deadline timestamps is limited. Org mode does not
|
||
know enough about the internals of each sexp function to issue early and
|
||
late warnings. However, it will show the item on each day where the
|
||
sexp entry matches.

@subsection Repeated tasks

|

@cindex repeated tasks
|
||
|
||
Some tasks need to be repeated again and again. Org mode helps to
|
||
organize such tasks using a so-called repeater in a DEADLINE, SCHEDULED,
|
||
or plain timestamp. In the following example
|
||
@example
|
||
** TODO Pay the rent
|
||
DEADLINE: <2005-10-01 Sat +1m>
|
||
@end example
|
||
@noindent
|
||
the @code{+1m} is a repeater; the intended interpretation is that the task
|
||
has a deadline on <2005-10-01> and repeats itself every (one) month starting
|
||
from that time. If you need both a repeater and a special warning period in
|
||
a deadline entry, the repeater should come first and the warning period last:
|
||
@code{DEADLINE: <2005-10-01 Sat +1m -3d>}.
|
||
|
||
@vindex org-todo-repeat-to-state
|
||
Deadlines and scheduled items produce entries in the agenda when they are
|
||
over-due, so it is important to be able to mark such an entry as completed
|
||
once you have done so. When you mark a DEADLINE or a SCHEDULE with the TODO
|
||
keyword DONE, it will no longer produce entries in the agenda. The problem
|
||
with this is, however, that then also the @emph{next} instance of the
|
||
repeated entry will not be active. Org mode deals with this in the following
|
||
way: When you try to mark such an entry DONE (using @kbd{C-c C-t}), it will
|
||
shift the base date of the repeating timestamp by the repeater interval, and
|
||
immediately set the entry state back to TODO@footnote{In fact, the target
|
||
state is taken from, in this sequence, the @code{REPEAT_TO_STATE} property or
|
||
the variable @code{org-todo-repeat-to-state}. If neither of these is
|
||
specified, the target state defaults to the first state of the TODO state
|
||
sequence.}. In the example above, setting the state to DONE would actually
|
||
switch the date like this:
|
||
|
||
@example
|
||
** TODO Pay the rent
|
||
DEADLINE: <2005-11-01 Tue +1m>
|
||
@end example
|
||
|
||
@vindex org-log-repeat
|
||
A timestamp@footnote{You can change this using the option
|
||
@code{org-log-repeat}, or the @code{#+STARTUP} options @code{logrepeat},
|
||
@code{lognoterepeat}, and @code{nologrepeat}. With @code{lognoterepeat}, you
|
||
will also be prompted for a note.} will be added under the deadline, to keep
|
||
a record that you actually acted on the previous instance of this deadline.
|
||
|
||
As a consequence of shifting the base date, this entry will no longer be
|
||
visible in the agenda when checking past dates, but all future instances
|
||
will be visible.
|
||
|
||
With the @samp{+1m} cookie, the date shift will always be exactly one
|
||
month. So if you have not paid the rent for three months, marking this
|
||
entry DONE will still keep it as an overdue deadline. Depending on the
|
||
task, this may not be the best way to handle it. For example, if you
|
||
forgot to call your father for 3 weeks, it does not make sense to call
|
||
him 3 times in a single day to make up for it. Finally, there are tasks
|
||
like changing batteries which should always repeat a certain time
|
||
@i{after} the last time you did it. For these tasks, Org mode has
|
||
special repeaters @samp{++} and @samp{.+}. For example:
|
||
|
||
@example
|
||
** TODO Call Father
|
||
DEADLINE: <2008-02-10 Sun ++1w>
|
||
Marking this DONE will shift the date by at least one week,
|
||
but also by as many weeks as it takes to get this date into

An alternative to using a repeater is to create a number of copies of a task

Org mode allows you to clock the time you spend on specific tasks in a
|
||
project. When you start working on an item, you can start the clock.
|
||
When you stop working on that task, or when you mark the task done, the
|
||
clock is stopped and the corresponding time interval is recorded. It
|
||
also computes the total time spent on each subtree of a project. And it
|
||
remembers a history or tasks recently clocked, to that you can jump quickly
|
||
between a number of tasks absorbing your time.
|
||
|
||
To save the clock history across Emacs sessions, use

@cindex property, LOG_INTO_DRAWER
|
||
Start the clock on the current item (clock-in). This inserts the CLOCK
|
||
keyword together with a timestamp. If this is not the first clocking of
|
||
this item, the multiple CLOCK lines will be wrapped into a
|
||
@code{:LOGBOOK:} drawer (see also the variable
|

@code{org-clock-into-drawer}). You can also overrule
|
||
the setting of this variable for a subtree by setting a
|
||
@code{CLOCK_INTO_DRAWER} or @code{LOG_INTO_DRAWER} property.
|
||
When called with a @kbd{C-u} prefix argument,
|
||
select the task from a list of recently clocked tasks. With two @kbd{C-u
|
||
C-u} prefixes, clock into the task at point and mark it as the default task.
|
||
The default task will always be available when selecting a clocking task,

@vindex org-clock-modeline-total
|
||
While the clock is running, the current clocking time is shown in the mode
|
||
line, along with the title of the task. The clock time shown will be all
|
||
time ever clocked for this task and its children. If the task has an effort
|
||
estimate (@pxref{Effort estimates}), the mode line displays the current
|
||
clocking time against it@footnote{To add an effort estimate ``on the fly'',
|
||
hook a function doing this to @code{org-clock-in-prepare-hook}.} If the task
|
||
is a repeating one (@pxref{Repeated tasks}), only the time since the last

reset of the task @footnote{as recorded by the @code{LAST_REPEAT} property}
|
||
will be shown. More control over what time is shown can be exercised with
|
||
the @code{CLOCK_MODELINE_TOTAL} property. It may have the values
|
||
@code{current} to show only the current clocking instance, @code{today} to
|
||
show all time clocked on this tasks today (see also the variable
|
||
@code{org-extend-today-until}), @code{all} to include all time, or

Stop the clock (clock-out). This inserts another timestamp at the same
|
||
location where the clock was last started. It also directly computes
|
||
the resulting time in inserts it after the time range as @samp{=>
|
||

@kindex C-c C-y
|
||
@kindex C-c C-c
|
||
@orgcmdkkc{C-c C-c,C-c C-y,org-evaluate-time-range}
|
||
Recompute the time interval after changing one of the timestamps. This
|
||
is only necessary if you edit the timestamps directly. If you change
|
||
them with @kbd{S-@key{cursor}} keys, the update is automatic.
|
||
@orgcmd{C-S-@key{up/down},org-clock-timestamps-up/down}
|

if it is running in this same item.
|

@orgcmd{C-c C-x C-x,org-clock-cancel}
|

mistake, or if you ended up working on something else.
|

prefix arg, select the target task from a list of recently clocked tasks.
|
||
@orgcmd{C-c C-x C-d,org-clock-display}
|

@vindex org-remove-highlights-with-change
|
||
Display time summaries for each subtree in the current buffer. This puts

overlays at the end of each headline, showing the total time recorded under
|

@cindex report, of clocked time
|
||
|
||
Org mode can produce quite complex reports based on the time clocking
|
||
information. Such a report is called a @emph{clock table}, because it is
|
||
formatted as one or several Org tables.
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-x C-r,org-clock-report}
|
||
Insert a dynamic block (@pxref{Dynamic blocks}) containing a clock
|
||
report as an Org mode table into the current file. When the cursor is
|
||
at an existing clock table, just update it. When called with a prefix
|
||
argument, jump to the first clock report in the current document and
|
||
update it. The clock table always includes also trees with
|
||
@code{:ARCHIVE:} tag.
|
||
@orgcmdkkc{C-c C-c,C-c C-x C-u,org-dblock-update}
|
||
Update dynamic block at point. The cursor needs to be in the
|
||
@code{#+BEGIN} line of the dynamic block.
|
||
@orgkey{C-u C-c C-x C-u}
|
||
Update all dynamic blocks (@pxref{Dynamic blocks}). This is useful if
|
||
you have several clock table blocks in a buffer.
|
||
@orgcmdkxkc{S-@key{left},S-@key{right},org-clocktable-try-shift}
|
||
Shift the current @code{:block} interval and update the table. The cursor
|
||
needs to be in the @code{#+BEGIN: clocktable} line for this command. If
|
||
@code{:block} is @code{today}, it will be shifted to @code{today-1} etc.
|
||
@end table
|
||
|
||
|
||
Here is an example of the frame for a clock table as it is inserted into the
|
||
buffer with the @kbd{C-c C-x C-r} command:
|
||
|
||
@cindex #+BEGIN, clocktable

@vindex org-clocktable-defaults
|

The @samp{BEGIN} line and specify a number of options to define the scope,
|
||
structure, and formatting of the report. Defaults for all these options can
|
||
be configured in the variable @code{org-clocktable-defaults}.
|
||
|

@noindent First there are options that determine which clock entries are to

be selected:

|
||
@r{Use @kbd{S-@key{left}/@key{right}} keys to shift the time interval.}
|

:tstart @r{A time string specifying when to start considering times.}
|

:tend @r{A time string specifying when to stop considering times.}
|
||
:step @r{@code{week} or @code{day}, to split the table into chunks.}
|

@r{To use this, @code{:block} or @code{:tstart}, @code{:tend} are needed.}
|

:stepskip0 @r{Do not show steps that have zero time.}
|

:tags @r{A tags match to select entries that should contribute. See}
|

@r{@ref{Matching tags and properties} for the match syntax.}
|
||
@end example
|
||
|
||
Then there are options which determine the formatting of the table. There
|
||
options are interpreted by the function @code{org-clocktable-write-default},
|
||
but you can specify your own function using the @code{:formatter} parameter.
|
||
@example
|

@r{DEADLINE, TIMESTAMP and TIMESTAMP_IA, in this order.}
|

@subsection Resolving idle time
|

@cindex resolve idle time
|
||
|
||
@cindex idle, resolve, dangling
|
||
If you clock in on a work item, and then walk away from your
|
||
computer---perhaps to take a phone call---you often need to ``resolve'' the
|
||
time you were away by either subtracting it from the current clock, or
|
||
applying it to another one.
|
||
|
||
@vindex org-clock-idle-time
|
||
By customizing the variable @code{org-clock-idle-time} to some integer, such
|
||
as 10 or 15, Emacs can alert you when you get back to your computer after
|
||
being idle for that many minutes@footnote{On computers using Mac OS X,
|
||
idleness is based on actual user idleness, not just Emacs' idle time. For
|
||
X11, you can install a utility program @file{x11idle.c}, available in the
|
||
UTILITIES directory of the Org git distribution, to get the same general
|
||
treatment of idleness. On other systems, idle time refers to Emacs idle time
|
||
only.}, and ask what you want to do with the idle time. There will be a
|
||
question waiting for you when you get back, indicating how much idle time has
|
||
passed (constantly updated with the current amount), as well as a set of
|
||
choices to correct the discrepancy:
|
||
|
||
@table @kbd
|
||
@item k
|
||
To keep some or all of the minutes and stay clocked in, press @kbd{k}. Org
|
||
will ask how many of the minutes to keep. Press @key{RET} to keep them all,
|
||
effectively changing nothing, or enter a number to keep that many minutes.
|
||
@item K
|
||
If you use the shift key and press @kbd{K}, it will keep however many minutes
|
||
you request and then immediately clock out of that task. If you keep all of
|
||
the minutes, this is the same as just clocking out of the current task.
|
||
@item s
|
||
To keep none of the minutes, use @kbd{s} to subtract all the away time from
|
||
the clock, and then check back in from the moment you returned.
|
||
@item S
|
||
To keep none of the minutes and just clock out at the start of the away time,
|
||
use the shift key and press @kbd{S}. Remember that using shift will always
|
||
leave you clocked out, no matter which option you choose.
|
||
@item C
|
||
To cancel the clock altogether, use @kbd{C}. Note that if instead of
|
||
canceling you subtract the away time, and the resulting clock amount is less
|
||
than a minute, the clock will still be canceled rather than clutter up the
|
||
log with an empty entry.
|
||
@end table
|
||
|
||
What if you subtracted those away minutes from the current clock, and now
|
||
want to apply them to a new clock? Simply clock in to any task immediately
|
||
after the subtraction. Org will notice that you have subtracted time ``on
|
||
the books'', so to speak, and will ask if you want to apply those minutes to
|
||
the next task you clock in on.
|
||
|
||
There is one other instance when this clock resolution magic occurs. Say you
|
||
were clocked in and hacking away, and suddenly your cat chased a mouse who
|
||
scared a hamster that crashed into your UPS's power button! You suddenly
|
||
lose all your buffers, but thanks to auto-save you still have your recent Org
|
||
mode changes, including your last clock in.
|
||
|
||
If you restart Emacs and clock into any task, Org will notice that you have a
|
||
dangling clock which was never clocked out from your last session. Using
|
||
that clock's starting time as the beginning of the unaccounted-for period,
|
||
Org will ask how you want to resolve that time. The logic and behavior is
|
||
identical to dealing with away time due to idleness; it is just happening due
|
||
to a recovery event rather than a set amount of idle time.
|
||
|
||
You can also check all the files visited by your Org agenda for dangling
|
||
clocks at any time using @kbd{M-x org-resolve-clocks}.

@vindex org-effort-property
|
||
If you want to plan your work in a very detailed way, or if you need to
|
||
produce offers with quotations of the estimated work effort, you may want to
|
||
assign effort estimates to entries. If you are also clocking your work, you
|
||
may later want to compare the planned effort with the actual working time, a
|
||
great way to improve planning estimates. Effort estimates are stored in a
|
||
special property @samp{Effort}@footnote{You may change the property being
|
||
used with the variable @code{org-effort-property}.}. You can set the effort
|
||
for an entry with the following commands:
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-x e,org-set-effort}
|
||
Set the effort estimate for the current entry. With a numeric prefix
|
||
argument, set it to the Nth allowed value (see below). This command is also
|
||
accessible from the agenda with the @kbd{e} key.
|
||
@orgcmd{C-c C-x C-e,org-clock-modify-effort-estimate}
|
||
Modify the effort estimate of the item currently being clocked.
|
||
@end table
|
||
|
||
Clearly the best way to work with effort estimates is through column view
|
||
(@pxref{Column view}). You should start by setting up discrete values for
|
||
effort estimates, and a @code{COLUMNS} format that displays these values
|
||
together with clock sums (if you want to clock your time). For a specific
|
||
buffer you can use
|
||
|
||
@example
|
||
#+PROPERTY: Effort_ALL 0 0:10 0:30 1:00 2:00 3:00 4:00 5:00 6:00 7:00
|
||
#+COLUMNS: %40ITEM(Task) %17Effort(Estimated Effort)@{:@} %CLOCKSUM
|
||
@end example
|
||
|
||
@noindent
|
||
@vindex org-global-properties
|
||
@vindex org-columns-default-format
|
||
or, even better, you can set up these values globally by customizing the
|
||
variables @code{org-global-properties} and @code{org-columns-default-format}.
|
||
In particular if you want to use this setup also in the agenda, a global
|
||
setup may be advised.
|
||
|
||
The way to assign estimates to individual items is then to switch to column
|
||
mode, and to use @kbd{S-@key{right}} and @kbd{S-@key{left}} to change the
|
||
value. The values you enter will immediately be summed up in the hierarchy.
|
||
In the column next to it, any clocked time will be displayed.
|
||
|
||
@vindex org-agenda-columns-add-appointments-to-effort-sum
|
||
If you switch to column view in the daily/weekly agenda, the effort column
|
||
will summarize the estimated work effort for each day@footnote{Please note
|
||
the pitfalls of summing hierarchical data in a flat list (@pxref{Agenda
|
||
column view}).}, and you can use this to find space in your schedule. To get
|
||
an overview of the entire part of the day that is committed, you can set the
|
||
option @code{org-agenda-columns-add-appointments-to-effort-sum}. The
|
||
appointments on a day that take place over a specified time interval will
|
||
then also be added to the load estimate of the day.
|
||
|
||
Effort estimates can be used in secondary agenda filtering that is triggered
|
||
with the @kbd{/} key in the agenda (@pxref{Agenda commands}). If you have
|
||
these estimates defined consistently, two or three key presses will narrow
|
||
down the list to stuff that fits into an available time slot.

timer will be started. When called with a prefix argument, the timer is
|
||
restarted.
|

@item C-u C-c C-x ,
|

Stop the timer. After this, you can only start a new timer, not continue the

||
old one. This command also removes the timer from the mode line.
|
||
@orgcmd{C-c C-x 0,org-timer-start}
|
||
Reset the timer without inserting anything into the buffer. By default, the
|
||
timer is reset to 0. When called with a @kbd{C-u} prefix, reset the timer to
|
||
specific starting offset. The user is prompted for the offset, with a
|
||
default taken from a timer string at point, if any, So this can be used to
|
||
restart taking notes after a break in the process. When called with a double
|
||
prefix argument @kbd{C-u C-u}, change all timer strings in the active region
|
||
by a certain amount. This can be used to fix timer strings if the timer was
|
||
not started at exactly the right moment.

@cindex capture
|
||
|
||
An important part of any organization system is the ability to quickly
|
||
capture new ideas and tasks, and to associate reference material with them.
|
||
Org does this using a process called @i{capture}. It also can store files
|
||
related to a task (@i{attachments}) in a special directory. Once in the
|
||
system, tasks and projects need to be moved around. Moving completed project
|
||
trees to an archive file keeps the system compact and fast.

@cindex capture
|
||
|
||
Org's method for capturing new items is heavily inspired by John Wiegley
|
||
excellent remember package. Up to version 6.36 Org used a special setup
|
||
for @file{remember.el}. @file{org-remember.el} is still part of Org mode for
|
||
backward compatibility with existing setups. You can find the documentation
|
||
for org-remember at @url{http://orgmode.org/org-remember.pdf}.
|
||
|
||
The new capturing setup described here is preferred and should be used by new
|
||
users. To convert your @code{org-remember-templates}, run the command
|
||
@example
|
||
@kbd{M-x org-capture-import-remember-templates @key{RET}}
|
||
@end example
|
||
@noindent and then customize the new variable with @kbd{M-x
|
||
customize-variable org-capture-templates}, check the result, and save the
|
||
customization. You can then use both remember and capture until
|
||
you are familiar with the new mechanism.
|
||
|
||
Capture lets you quickly store notes with little interruption of your work
|
||
flow. The basic process of capturing is very similar to remember, but Org
|
||
does enhance it with templates and more.

|
||
|
||
The following customization sets a default target file for notes, and defines
|
||
a global key@footnote{Please select your own key, @kbd{C-c c} is only a
|
||
suggestion.} for capturing new material.
|
||
|
||
@vindex org-default-notes-file
|
||
@example
|

(setq org-default-notes-file (concat org-directory "/notes.org"))

|
||
@subsection Using capture
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c c,org-capture}
|
||
Call the command @code{org-capture}. Note that this keybinding is global and
|
||
not active by default - you need to install it. If you have templates
|
||
@cindex date tree
|
||
defined @pxref{Capture templates}, it will offer these templates for
|
||
selection or use a new Org outline node as the default template. It will
|
||
insert the template into the target file and switch to an indirect buffer
|
||
narrowed to this new node. You may then insert the information you want.
|
||
|
||
@orgcmd{C-c C-c,org-capture-finalize}
|
||
Once you have finished entering information into the capture buffer, @kbd{C-c
|
||
C-c} will return you to the window configuration before the capture process,
|
||
so that you can resume your work without further distraction. When called
|
||
with a prefix arg, finalize and then jump to the captured item.
|
||
|
||
@orgcmd{C-c C-w,org-capture-refile}
|
||
Finalize the capture process by refiling (@pxref{Refiling notes}) the note to
|
||
a different place. Please realize that this is a normal refiling command
|
||
that will be executed---so the cursor position at the moment you run this
|
||
command is important. If you have inserted a tree with a parent and
|
||
children, first move the cursor back to the parent. Any prefix argument
|
||
given to this command will be passed on to the @code{org-refile} command.
|
||
|
||
@orgcmd{C-c C-k,org-capture-kill}
|
||
Abort the capture process and return to the previous state.
|
||
|
||
@end table
|
||
|
||
You can also call @code{org-capture} in a special way from the agenda, using
|
||
the @kbd{k c} key combination. With this access, any timestamps inserted by
|
||
the selected capture template will default to the cursor date in the agenda,
|
||
rather than to the current date.
|
||
|
||
To find the locations of the last stored capture, use @code{org-capture} with
|
||
prefix commands:
|
||
|
||
@table @kbd
|
||
@orgkey{C-u C-c c}
|
||
Visit the target location of a capture template. You get to select the
|
||
template in the usual way.
|
||
@orgkey{C-u C-u C-c c}
|
||
Visit the last stored capture item in its buffer.
|
||
@end table
|
||
|
||
@node Capture templates, , Using capture, Capture
|
||
@subsection Capture templates
|
||
@cindex templates, for Capture
|
||
|
||
You can use templates for different types of capture items, and
|
||
for different target locations. The easiest way to create such templates is
|
||
through the customize interface.
|
||
|
||
@table @kbd
|
||
@orgkey{C-c c C}
|
||
Customize the variable @code{org-capture-templates}.
|
||
@end table
|
||
|
||
Before we give the formal description of template definitions, let's look at
|
||
an example. Say you would like to use one template to create general TODO
|
||
entries, and you want to put these entries under the heading @samp{Tasks} in
|
||
your file @file{~/org/gtd.org}. Also, a date tree in the file
|
||
@file{journal.org} should capture journal entries. A possible configuration
|
||
would look like:
|
||
|
||
@example
|
||
(setq org-capture-templates
|
||
'(("t" "Todo" entry (file+headline "~/org/gtd.org" "Tasks")
|
||
"* TODO %?\n %i\n %a")
|
||
("j" "Journal" entry (file+datetree "~/org/journal.org")
|
||
"* %?\nEntered on %U\n %i\n %a")))
|
||
@end example
|
||
|
||
@noindent If you then press @kbd{C-c c t}, Org will prepare the template
|
||
for you like this:
|
||
@example
|
||
* TODO
|
||
[[file:@var{link to where you initiated capture}]]
|
||
@end example
|
||
|
||
@noindent
|
||
During expansion of the template, @code{%a} has been replaced by a link to
|
||
the location from where you called the capture command. This can be
|
||
extremely useful for deriving tasks from emails, for example. You fill in
|
||
the task definition, press @code{C-c C-c} and Org returns you to the same
|
||
place where you started the capture process.
|
||
|
||
To define special keys to capture to a particular template without going
|
||
through the interactive template selection, you can create your key binding
|
||
like this:
|
||
|
||
@lisp
|
||
(define-key global-map "\C-cx"
|
||
(lambda () (interactive) (org-capture nil "x")))
|
||
@end lisp

|
||
@end menu
|
||
|
||
@node Template elements, Template expansion, Capture templates, Capture templates
|
||
@subsubsection Template elements
|
||
|
||
Now lets look at the elements of a template definition. Each entry in
|
||
@code{org-capture-templates} is a list with the following items:
|
||
|
||
@table @var
|
||
@item keys
|
||
The keys that will select the template, as a string, characters
|
||
only, for example @code{"a"} for a template to be selected with a
|
||
single key, or @code{"bt"} for selection with two keys. When using
|
||
several keys, keys using the same prefix key must be sequential
|
||
in the list and preceded by a 2-element entry explaining the
|
||
prefix key, for example
|
||
@example
|
||
("b" "Templates for marking stuff to buy")
|
||
@end example
|
||
@noindent If you do not define a template for the @kbd{C} key, this key will
|
||
be used to open the customize buffer for this complex variable.
|
||
|
||
@item description
|
||
A short string describing the template, which will be shown during
|
||
selection.
|
||
|
||
@item type
|
||
The type of entry, a symbol. Valid values are:
|
||
@table @code
|
||
@item entry
|
||
An Org mode node, with a headline. Will be filed as the child of the target
|
||
entry or as a top-level entry. The target file should be an Org mode file.
|
||
@item item
|
||
A plain list item, placed in the first plain list at the target
|
||
location. Again the target file should be an Org file.
|
||
@item checkitem
|
||
A checkbox item. This only differs from the plain list item by the
|
||
default template.
|
||
@item table-line
|
||
a new line in the first table at the target location. Where exactly the
|
||
line will be inserted depends on the properties @code{:prepend} and
|
||
@code{:table-line-pos} (see below).
|
||
@item plain
|
||
Text to be inserted as it is.
|
||
@end table
|
||
|
||
@item target
|
||
@vindex org-default-notes-file
|
||
Specification of where the captured item should be placed. In Org mode
|
||
files, targets usually define a node. Entries will become children of this
|
||
node. Other types will be added to the table or list in the body of this
|
||
node. Most target specifications contain a file name. If that file name is
|
||
the empty string, it defaults to @code{org-default-notes-file}. A file can
|
||
also be given as a variable, function, or Emacs Lisp form.
|
||
|
||
Valid values are:
|
||
@table @code
|
||
@item (file "path/to/file")
|
||
Text will be placed at the beginning or end of that file.
|
||
|
||
@item (id "id of existing org entry")
|
||
Filing as child of this entry, or in the body of the entry.
|
||
|
||
@item (file+headline "path/to/file" "node headline")
|
||
Fast configuration if the target heading is unique in the file.
|
||
|
||
@item (file+olp "path/to/file" "Level 1 heading" "Level 2" ...)
|
||
For non-unique headings, the full path is safer.
|
||
|
||
@item (file+regexp "path/to/file" "regexp to find location")
|
||
Use a regular expression to position the cursor.
|
||
|
||
@item (file+datetree "path/to/file")
|
||
Will create a heading in a date tree for today's date.
|
||
|
||
@item (file+datetree+prompt "path/to/file")
|
||
Will create a heading in a date tree, but will prompt for the date.
|
||
|
||
@item (file+function "path/to/file" function-finding-location)
|
||
A function to find the right location in the file.
|
||
|
||
@item (clock)
|
||
File to the entry that is currently being clocked.
|
||
|
||
@item (function function-finding-location)
|
||
Most general way, write your own function to find both
|
||
file and location.
|
||
@end table
|
||
|
||
@item template
|
||
The template for creating the capture item. If you leave this empty, an
|
||
appropriate default template will be used. Otherwise this is a string with
|
||
escape codes, which will be replaced depending on time and context of the
|
||
capture call. The string with escapes may be loaded from a template file,
|
||
using the special syntax @code{(file "path/to/template")}. See below for
|
||
more details.
|
||
|
||
@item properties
|
||
The rest of the entry is a property list of additional options.
|
||
Recognized properties are:
|
||
@table @code
|
||
@item :prepend
|
||
Normally new captured information will be appended at
|
||
the target location (last child, last table line, last list item...).
|
||
Setting this property will change that.
|
||
|
||
@item :immediate-finish
|
||
When set, do not offer to edit the information, just
|
||
file it away immediately. This makes sense if the template only needs
|
||
information that can be added automatically.
|
||
|
||
@item :empty-lines
|
||
Set this to the number of lines to insert
|
||
before and after the new item. Default 0, only common other value is 1.
|
||
|
||
@item :clock-in
|
||
Start the clock in this item.
|
||
|
||
@item :clock-keep
|
||
Keep the clock running when filing the captured entry.
|
||
|
||
@item :clock-resume
|
||
If starting the capture interrupted a clock, restart that clock when finished
|
||
with the capture. Note that @code{:clock-keep} has precedence over
|
||
@code{:clock-resume}. When setting both to @code{t}, the current clock will
|
||
run and the previous one will not be resumed.
|
||
|
||
@item :unnarrowed
|
||
Do not narrow the target buffer, simply show the full buffer. Default is to
|
||
narrow it so that you only see the new material.
|
||
|
||
@item :table-line-pos
|
||
Specification of the location in the table where the new line should be
|
||
inserted. It should be a string like @code{"II-3"} meaning that the new
|
||
line should become the third line before the second horizontal separator
|
||
line.
|
||
|
||
@item :kill-buffer
|
||
If the target file was not yet visited when capture was invoked, kill the
|
||
buffer again after capture is completed.

|
||
It is often useful to associate reference material with an outline node/task.
|
||
Small chunks of plain text can simply be stored in the subtree of a project.
|
||
Hyperlinks (@pxref{Hyperlinks}) can establish associations with
|
||
files that live elsewhere on your computer or in the cloud, like emails or
|
||
source code files belonging to a project. Another method is @i{attachments},
|
||
which are files located in a directory belonging to an outline node. Org
|
||
uses directories named by the unique ID of each entry. These directories are
|
||
located in the @file{data} directory which lives in the same directory where
|
||
your Org file lives@footnote{If you move entries or Org files from one
|
||
directory to another, you may want to configure @code{org-attach-directory}
|
||
to contain an absolute path.}. If you initialize this directory with
|
||
@code{git init}, Org will automatically commit changes when it sees them.
|
||
The attachment system has been contributed to Org by John Wiegley.
|
||
|
||
In cases where it seems better to do so, you can also attach a directory of your
|
||
choice to an entry. You can also make children inherit the attachment
|
||
directory from a parent, so that an entire subtree uses the same attached
|
||
directory.
|
||
|
||
@noindent The following commands deal with attachments:
|
||
|
||
@table @kbd
|
||
|
||
@orgcmd{C-c C-a,org-attach}
|
||
The dispatcher for commands related to the attachment system. After these
|
||
keys, a list of commands is displayed and you must press an additional key
|
||
to select a command:
|
||
|
||
@table @kbd
|
||
@orgcmdtkc{a,C-c C-a a,org-attach-attach}
|
||
@vindex org-attach-method
|
||
Select a file and move it into the task's attachment directory. The file

Org can add and change entries based on information found in RSS feeds and
|
||
Atom feeds. You could use this to make a task out of each new podcast in a
|
||
podcast feed. Or you could use a phone-based note-creating service on the
|
||
web to import tasks into Org. To access feeds, configure the variable
|
||
@code{org-feed-alist}. The docstring of this variable has detailed
|
||
information. Here is just an example:
|
||
|
||
@example
|
||
(setq org-feed-alist
|
||
'(("Slashdot"
|
||
"http://rss.slashdot.org/Slashdot/slashdot"
|
||
"~/txt/org/feeds.org" "Slashdot Entries")))
|
||
@end example
|
||
|
||
@noindent
|
||
will configure that new items from the feed provided by
|
||
@code{rss.slashdot.org} will result in new entries in the file
|
||
@file{~/org/feeds.org} under the heading @samp{Slashdot Entries}, whenever
|
||
the following command is used:
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-x g,org-feed-update-all}
|
||
@item C-c C-x g
|
||
Collect items from the feeds configured in @code{org-feed-alist} and act upon
|
||
them.
|
||
@orgcmd{C-c C-x G,org-feed-goto-inbox}
|
||
Prompt for a feed name and go to the inbox configured for this feed.
|
||
@end table
|
||
|
||
Under the same headline, Org will create a drawer @samp{FEEDSTATUS} in which
|
||
it will store information about the status of items in the feed, to avoid
|
||
adding the same item several times. You should add @samp{FEEDSTATUS} to the
|
||
list of drawers in that file:
|
||
|
||
@example
|
||
#+DRAWERS: LOGBOOK PROPERTIES FEEDSTATUS
|

could create a bookmark that will tell Emacs to open the local source file of

@cindex refiling notes
|
||
|
||
When reviewing the captured data, you may want to refile some of the entries
|
||
into a different list, for example into a project. Cutting, finding the
|
||
right location, and then pasting the note is cumbersome. To simplify this
|
||
process, you can use the following special command:
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-w,org-refile}
|
||
@vindex org-reverse-note-order
|

|
||
@vindex org-refile-allow-creating-parent-nodes
|
||
@vindex org-log-refile
|
||
@vindex org-refile-use-cache
|
||
Refile the entry or region at point. This command offers possible locations
|
||
for refiling the entry and lets you select one with completion. The item (or
|
||
all items in the region) is filed below the target heading as a subitem.
|
||
Depending on @code{org-reverse-note-order}, it will be either the first or
|
||
last subitem.@*
|
||
By default, all level 1 headlines in the current buffer are considered to be
|
||
targets, but you can have more complex definitions across a number of files.
|
||
See the variable @code{org-refile-targets} for details. If you would like to
|
||
select a location via a file-path-like completion along the outline path, see
|
||
the variables @code{org-refile-use-outline-path} and
|
||
@code{org-outline-path-complete-in-steps}. If you would like to be able to
|
||
create new nodes as new parents for refiling on the fly, check the
|
||
variable @code{org-refile-allow-creating-parent-nodes}.
|
||
When the variable @code{org-log-refile}@footnote{with corresponding
|
||
@code{#+STARTUP} keywords @code{logrefile}, @code{lognoterefile},
|
||
and @code{nologrefile}} is set, a timestamp or a note will be
|
||
recorded when an entry has been refiled.
|
||
@orgkey{C-u C-c C-w}
|
||
Use the refile interface to jump to a heading.
|
||
@orgcmd{C-u C-u C-c C-w,org-refile-goto-last-stored}
|
||
Jump to the location where @code{org-refile} last moved a tree to.
|
||
@item C-2 C-c C-w
|
||
Refile as the child of the item currently being clocked.
|
||
@orgcmdtkc{C-0 C-c C-w @ @r{or} @ C-u C-u C-u C-c C-w,C-0 C-c C-w,org-refile-cache-clear}
|
||
Clear the target cache. Caching of refile targets can be turned on by
|
||
setting @code{org-refile-use-cache}. To make the command see new possible
|
||
targets, you have to clear the cache with this command.

@orgkey{C-u C-c C-x C-s}
|

Check if any direct children of the current headline could be moved to

the archive. To do this, each subtree is checked for open TODO entries.
|

If none are found, the command offers to move it to the archive

@cindex archive locations

The default archive location is a file in the same directory as the

||
current file name. For information and examples on how to change this,
|
||
see the documentation string of the variable
|
||
@code{org-archive-location}. There is also an in-buffer option for
|
||
setting this variable, for example@footnote{For backward compatibility,
|
||
the following also works: If there are several such lines in a file,
|
||
each specifies the archive location for the text below it. The first
|
||
such line also applies to any text before its definition. However,
|
||
using this method is @emph{strongly} deprecated as it is incompatible
|
||
with the outline structure of the document. The correct method for
|
||
setting multiple archive locations in a buffer is using properties.}:

|
||
location as the value (@pxref{Properties and Columns}).
|
||
|
||
@vindex org-archive-save-context-info
|
||
When a subtree is moved, it receives a number of special properties that
|
||
record context information like the file from where the entry came, its

outline path the archiving time etc. Configure the variable
|

@code{org-archive-save-context-info} to adjust the amount of information

If you want to just switch off (for agenda views) certain subtrees without

|
||
|
||
A headline that is marked with the ARCHIVE tag (@pxref{Tags}) stays at
|
||
its location in the outline tree, but behaves in the following way:
|
||
@itemize @minus
|
||
@item
|
||
@vindex org-cycle-open-archived-trees
|
||
It does not open when you attempt to do so with a visibility cycling

||
command (@pxref{Visibility cycling}). You can force cycling archived
|
||
subtrees with @kbd{C-@key{TAB}}, or by setting the option
|
||
@code{org-cycle-open-archived-trees}. Also normal outline commands like
|
||
@code{show-all} will open archived subtrees.
|
||
@item
|

@vindex org-sparse-tree-open-archived-trees
|
||
During sparse tree construction (@pxref{Sparse trees}), matches in

@code{org-sparse-tree-open-archived-trees}.
|
||
@item
|

@vindex org-agenda-skip-archived-trees
|
||
During agenda view construction (@pxref{Agenda Views}), the content of
|
||
archived trees is ignored unless you configure the option
|
||
@code{org-agenda-skip-archived-trees}, in which case these trees will always
|
||
be included. In the agenda you can press @kbd{v a} to get archives
|
||
temporarily included.
|
||
@item
|
||
@vindex org-export-with-archived-trees
|

@code{org-export-with-archived-trees}.
|

The following commands help manage the ARCHIVE tag:
|
||
|

@table @kbd
|
||
@orgcmd{C-c C-x a,org-toggle-archive-tag}
|
||
Toggle the ARCHIVE tag for the current headline. When the tag is set,
|
||
the headline changes to a shadowed face, and the subtree below it is
|
||
hidden.
|
||
@orgkey{C-u C-c C-x a}
|
||
Check if any direct children of the current headline should be archived.
|
||
To do this, each subtree is checked for open TODO entries. If none are
|
||
found, the command offers to set the ARCHIVE tag for the child. If the
|
||
cursor is @emph{not} on a headline when this command is invoked, the
|
||
level 1 trees will be checked.
|
||
@orgcmd{C-@kbd{TAB},org-force-cycle-archived}
|
||
Cycle a tree even if it is tagged with ARCHIVE.
|
||
@orgcmd{C-c C-x A,org-archive-to-archive-sibling}
|
||
Move the current entry to the @emph{Archive Sibling}. This is a sibling of
|
||
the entry with the heading @samp{Archive} and the tag @samp{ARCHIVE}. The
|
||
entry becomes a child of that sibling and in this way retains a lot of its

||
original context, including inherited tags and approximate position in the

Due to the way Org works, TODO items, time-stamped items, and

||
sorted and displayed in an organized way.
|

Org can select items based on various criteria and display them
|

in a separate buffer. Seven different view types are provided:
|

an @emph{agenda} that is like a calendar and shows information
|

action items,

a @emph{match view}, showings headlines based on the tags, properties, and

a @emph{stuck projects view} showing projects that currently don't move

@cindex weekly agenda
|

@cindex daily agenda
|

paper agenda, showing all the tasks for the current week or day.
|
||
|
||
@table @kbd
|

@cindex org-agenda, command
|

@orgcmd{C-c a a,org-agenda-list}
|
||
Compile an agenda for the current week from a list of Org files. The agenda
|
||
shows the entries for each day. With a numeric prefix@footnote{For backward
|
||
compatibility, the universal prefix @kbd{C-u} causes all TODO entries to be
|
||
listed before the agenda. This feature is deprecated, use the dedicated TODO
|
||
list, or a block agenda instead (@pxref{Block agenda}).} (like @kbd{C-u 2 1
|
||
C-c a a}) you may set the number of days to be displayed.
|
||
@end table
|
||
|
||
@vindex org-agenda-span
|
||
@vindex org-agenda-ndays
|
||
The default number of days displayed in the agenda is set by the variable
|
||
@code{org-agenda-span} (or the obsolete @code{org-agenda-ndays}). This
|
||
variable can be set to any number of days you want to see by default in the

agenda, or to a span name, such a @code{day}, @code{week}, @code{month} or
|
||
@code{year}.
|

Remote editing from the agenda buffer means, for example, that you can

||
change the dates of deadlines and appointments from the agenda buffer.

@subsubheading Calendar/Diary integration
|
||
@cindex calendar integration
|
||
@cindex diary integration
|
||
|
||
Emacs contains the calendar and diary by Edward M. Reingold. The
|
||
calendar displays a three-month calendar with holidays from different
|
||
countries and cultures. The diary allows you to keep track of
|
||
anniversaries, lunar phases, sunrise/set, recurrent appointments
|
||
(weekly, monthly) and more. In this way, it is quite complementary to
|
||
Org. It can be very useful to combine output from Org with
|
||
the diary.
|
||
|
||
In order to include entries from the Emacs diary into Org mode's
|
||
agenda, you only need to customize the variable
|
||
|
||
@lisp
|
||
(setq org-agenda-include-diary t)
|
||
@end lisp
|
||
|
||
@noindent After that, everything will happen automatically. All diary
|
||
entries including holidays, anniversaries, etc., will be included in the
|
||
agenda buffer created by Org mode. @key{SPC}, @key{TAB}, and
|
||
@key{RET} can be used from the agenda buffer to jump to the diary
|
||
file in order to edit existing diary entries. The @kbd{i} command to
|
||
insert new entries for the current date works in the agenda buffer, as
|
||
well as the commands @kbd{S}, @kbd{M}, and @kbd{C} to display
|
||
Sunrise/Sunset times, show lunar phases and to convert to other
|
||
calendars, respectively. @kbd{c} can be used to switch back and forth
|
||
between calendar and agenda.
|
||
|
||
If you are using the diary only for sexp entries and holidays, it is
|
||
faster to not use the above setting, but instead to copy or even move
|
||
the entries into an Org file. Org mode evaluates diary-style sexp
|
||
entries, and does it faster because there is no overhead for first
|
||
creating the diary display. Note that the sexp entries must start at
|
||
the left margin, no whitespace is allowed before them. For example,
|
||
the following segment of an Org file will be processed and entries
|
||
will be made in the agenda:
|
||
|
||
@example
|
||
* Birthdays and similar stuff
|
||
#+CATEGORY: Holiday
|
||
%%(org-calendar-holiday) ; special function for holiday names
|
||
#+CATEGORY: Ann
|
||
%%(org-anniversary 1956 5 14)@footnote{@code{org-anniversary} is just like @code{diary-anniversary}, but the argument order is always according to ISO and therefore independent of the value of @code{calendar-date-style}.} Arthur Dent is %d years old
|
||
%%(org-anniversary 1869 10 2) Mahatma Gandhi would be %d years old

@subsubheading Anniversaries from BBDB

|

@cindex anniversaries, from BBDB
|
||
|
||
If you are using the Big Brothers Database to store your contacts, you will
|
||
very likely prefer to store anniversaries in BBDB rather than in a
|
||
separate Org or diary file. Org supports this and will show BBDB
|
||
anniversaries as part of the agenda. All you need to do is to add the
|
||
following to one of your agenda files:
|
||
|
||
@example
|
||
* Anniversaries
|
||
:PROPERTIES:
|
||
:CATEGORY: Anniv
|
||
:END:
|
||
%%(org-bbdb-anniversaries)
|
||
@end example
|
||
|
||
You can then go ahead and define anniversaries for a BBDB record. Basically,
|
||
you need to press @kbd{C-o anniversary @key{RET}} with the cursor in a BBDB
|
||
record and then add the date in the format @code{YYYY-MM-DD} or @code{MM-DD},
|
||
followed by a space and the class of the anniversary (@samp{birthday} or
|
||
@samp{wedding}, or a format string). If you omit the class, it will default to
|
||
@samp{birthday}. Here are a few examples, the header for the file
|
||
@file{org-bbdb.el} contains more detailed information.
|
||
|
||
@example
|
||
1973-06-22
|
||
06-22
|
||
1955-08-02 wedding
|
||
2008-04-14 %s released version 6.01 of org mode, %d years ago
|
||
@end example
|
||
|
||
After a change to BBDB, or for the first agenda display during an Emacs
|
||
session, the agenda display will suffer a short delay as Org updates its
|
||
hash with anniversaries. However, from then on things will be very fast---much
|
||
faster in fact than a long list of @samp{%%(diary-anniversary)} entries
|
||
in an Org or Diary file.

|

|
||
Org can interact with Emacs appointments notification facility. To add all
|
||
the appointments of your agenda files, use the command
|
||
@code{org-agenda-to-appt}. This command also lets you filter through the
|
||
list of your appointments and add only those belonging to a specific category
|
||
or matching a regular expression. See the docstring for details.

@subsection The global TODO list
|

@cindex global TODO list
|
||
@cindex TODO list, global
|
||
|
||
The global TODO list contains all unfinished TODO items formatted and
|
||
collected into a single place.
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c a t,org-todo-list}
|
||
Show the global TODO list. This collects the TODO items from all agenda
|
||
files (@pxref{Agenda Views}) into a single buffer. By default, this lists
|
||
items with a state the is not a DONE state. The buffer is in
|
||
@code{agenda-mode}, so there are commands to examine and manipulate the TODO
|
||
entries directly from that buffer (@pxref{Agenda commands}).
|
||
@orgcmd{C-c a T,org-todo-list}
|
||
@cindex TODO keyword matching
|
||
@vindex org-todo-keywords
|
||
Like the above, but allows selection of a specific TODO keyword. You can
|
||
also do this by specifying a prefix argument to @kbd{C-c a t}. You are
|
||
prompted for a keyword, and you may also specify several keywords by
|
||
separating them with @samp{|} as the boolean OR operator. With a numeric
|
||
prefix, the Nth keyword in @code{org-todo-keywords} is selected.
|
||
@kindex r
|
||
The @kbd{r} key in the agenda buffer regenerates it, and you can give
|
||
a prefix argument to this command to change the selected TODO keyword,
|
||
for example @kbd{3 r}. If you often need a search for a specific
|
||
keyword, define a custom command for it (@pxref{Agenda dispatcher}).@*
|
||
Matching specific TODO keywords can also be done as part of a tags
|
||
search (@pxref{Tag searches}).
|
||
@end table
|
||
|
||
Remote editing of TODO items means that you can change the state of a
|
||
TODO entry with a single key press. The commands available in the
|
||
TODO list are described in @ref{Agenda commands}.
|
||
|
||
@cindex sublevels, inclusion into TODO list
|
||
Normally the global TODO list simply shows all headlines with TODO
|
||
keywords. This list can become very long. There are two ways to keep
|
||
it more compact:
|
||
@itemize @minus
|
||
@item
|
||
@vindex org-agenda-todo-ignore-scheduled
|
||
@vindex org-agenda-todo-ignore-deadlines
|
||
@vindex org-agenda-todo-ignore-timestamp
|
||
@vindex org-agenda-todo-ignore-with-date
|
||
Some people view a TODO item that has been @emph{scheduled} for execution or
|
||
have a @emph{deadline} (@pxref{Timestamps}) as no longer @emph{open}.
|
||
Configure the variables @code{org-agenda-todo-ignore-scheduled},
|
||
@code{org-agenda-todo-ignore-deadlines},
|
||
@code{org-agenda-todo-ignore-timestamp} and/or
|
||
@code{org-agenda-todo-ignore-with-date} to exclude such items from the global
|
||
TODO list.
|
||
@item
|
||
@vindex org-agenda-todo-list-sublevels
|
||
TODO items may have sublevels to break up the task into subtasks. In
|
||
such cases it may be enough to list only the highest level TODO headline
|
||
and omit the sublevels from the global list. Configure the variable
|
||
@code{org-agenda-todo-list-sublevels} to get this behavior.

@cindex match view
|

|

If headlines in the agenda files are marked with @emph{tags} (@pxref{Tags}),
|
||
or have properties (@pxref{Properties and Columns}), you can select headlines
|
||
based on this metadata and collect them into an agenda buffer. The match
|
||
syntax described here also applies when creating sparse trees with @kbd{C-c /
|
||
m}.
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c a m,org-tags-view}
|
||
Produce a list of all headlines that match a given set of tags. The
|
||
command prompts for a selection criterion, which is a boolean logic
|
||
expression with tags, like @samp{+work+urgent-withboss} or
|
||
@samp{work|home} (@pxref{Tags}). If you often need a specific search,
|
||
define a custom command for it (@pxref{Agenda dispatcher}).
|
||
@orgcmd{C-c a M,org-tags-view}
|
||
@vindex org-tags-match-list-sublevels
|
||
@vindex org-agenda-tags-todo-honor-ignore-options
|
||
Like @kbd{C-c a m}, but only select headlines that are also TODO items in a
|
||
not-DONE state and force checking subitems (see variable
|
||
@code{org-tags-match-list-sublevels}). To exclude scheduled/deadline items,
|
||
see the variable @code{org-agenda-tags-todo-honor-ignore-options}. Matching
|
||
specific TODO keywords together with a tags match is also possible, see
|
||
@ref{Tag searches}.

The commands available in the tags list are described in @ref{Agenda

|

||
@subsubheading Match syntax
|
||
|
||
@cindex Boolean logic, for tag/property searches
|
||
A search string can use Boolean operators @samp{&} for AND and @samp{|} for
|
||
OR. @samp{&} binds more strongly than @samp{|}. Parentheses are currently
|
||
not implemented. Each element in the search is either a tag, a regular
|
||
expression matching tags, or an expression like @code{PROPERTY OPERATOR
|
||
VALUE} with a comparison operator, accessing a property value. Each element
|
||
may be preceded by @samp{-}, to select against it, and @samp{+} is syntactic
|
||
sugar for positive selection. The AND operator @samp{&} is optional when
|
||
@samp{+} or @samp{-} is present. Here are some examples, using only tags.
|
||
|
||
@table @samp
|
||
@item +work-boss
|
||
Select headlines tagged @samp{:work:}, but discard those also tagged
|
||
@samp{:boss:}.
|
||
@item work|laptop
|
||
Selects lines tagged @samp{:work:} or @samp{:laptop:}.
|
||
@item work|laptop+night
|
||
Like before, but require the @samp{:laptop:} lines to be tagged also
|
||
@samp{:night:}.
|
||
@end table
|
||
|
||
@cindex regular expressions, with tags search
|
||
Instead of a tag, you may also specify a regular expression enclosed in curly
|
||
braces. For example,
|
||
@samp{work+@{^boss.*@}} matches headlines that contain the tag
|
||
@samp{:work:} and any tag @i{starting} with @samp{boss}.
|
||
|
||
@cindex TODO keyword matching, with tags search
|
||
@cindex level, require for tags/property match
|
||
@cindex category, require for tags/property match
|
||
@vindex org-odd-levels-only
|
||
You may also test for properties (@pxref{Properties and Columns}) at the same
|
||
time as matching tags. The properties may be real properties, or special
|
||
properties that represent other metadata (@pxref{Special properties}). For
|
||
example, the ``property'' @code{TODO} represents the TODO keyword of the
|
||
entry. Or, the ``property'' @code{LEVEL} represents the level of an entry.
|
||
So a search @samp{+LEVEL=3+boss-TODO="DONE"} lists all level three headlines
|
||
that have the tag @samp{boss} and are @emph{not} marked with the TODO keyword
|
||
DONE. In buffers with @code{org-odd-levels-only} set, @samp{LEVEL} does not
|
||
count the number of stars, but @samp{LEVEL=2} will correspond to 3 stars etc.
|
||
|
||
Here are more examples:
|
||
@table @samp
|
||
@item work+TODO="WAITING"
|
||
Select @samp{:work:}-tagged TODO lines with the specific TODO
|
||
keyword @samp{WAITING}.
|
||
@item work+TODO="WAITING"|home+TODO="WAITING"
|
||
Waiting tasks both at work and at home.
|
||
@end table
|
||
|
||
When matching properties, a number of different operators can be used to test
|
||
the value of a property. Here is a complex example:
|
||
|
||
@example
|
||
+work-boss+PRIORITY="A"+Coffee="unlimited"+Effort<2 \
|
||
+With=@{Sarah\|Denny@}+SCHEDULED>="<2008-10-11>"
|
||
@end example
|
||
|
||
@noindent
|
||
The type of comparison will depend on how the comparison value is written:
|
||
@itemize @minus
|
||
@item
|
||
If the comparison value is a plain number, a numerical comparison is done,
|
||
and the allowed operators are @samp{<}, @samp{=}, @samp{>}, @samp{<=},
|
||
@samp{>=}, and @samp{<>}.
|
||
@item
|
||
If the comparison value is enclosed in double-quotes,
|
||
a string comparison is done, and the same operators are allowed.
|
||
@item
|
||
If the comparison value is enclosed in double-quotes @emph{and} angular
|
||
brackets (like @samp{DEADLINE<="<2008-12-24 18:30>"}), both values are
|
||
assumed to be date/time specifications in the standard Org way, and the
|
||
comparison will be done accordingly. Special values that will be recognized
|
||
are @code{"<now>"} for now (including time), and @code{"<today>"}, and
|
||
@code{"<tomorrow>"} for these days at 0:00 hours, i.e.@: without a time
|
||
specification. Also strings like @code{"<+5d>"} or @code{"<-2m>"} with units
|
||
@code{d}, @code{w}, @code{m}, and @code{y} for day, week, month, and year,
|
||
respectively, can be used.
|
||
@item
|
||
If the comparison value is enclosed
|
||
in curly braces, a regexp match is performed, with @samp{=} meaning that the
|
||
regexp matches the property value, and @samp{<>} meaning that it does not
|
||
match.
|
||
@end itemize
|
||
|
||
So the search string in the example finds entries tagged @samp{:work:} but
|
||
not @samp{:boss:}, which also have a priority value @samp{A}, a
|
||
@samp{:Coffee:} property with the value @samp{unlimited}, an @samp{Effort}
|
||
property that is numerically smaller than 2, a @samp{:With:} property that is
|
||
matched by the regular expression @samp{Sarah\|Denny}, and that are scheduled
|
||
on or after October 11, 2008.
|
||
|
||
Accessing TODO, LEVEL, and CATEGORY during a search is fast. Accessing any
|
||
other properties will slow down the search. However, once you have paid the
|
||
price by accessing one property, testing additional properties is cheap
|
||
again.
|
||
|
||
You can configure Org mode to use property inheritance during a search, but
|
||
beware that this can slow down searches considerably. See @ref{Property
|
||
inheritance}, for details.
|
||
|
||
For backward compatibility, and also for typing speed, there is also a
|
||
different way to test TODO states in a search. For this, terminate the
|
||
tags/property part of the search string (which may include several terms
|
||
connected with @samp{|}) with a @samp{/} and then specify a Boolean
|
||
expression just for TODO keywords. The syntax is then similar to that for
|
||
tags, but should be applied with care: for example, a positive selection on
|
||
several TODO keywords cannot meaningfully be combined with boolean AND.
|
||
However, @emph{negative selection} combined with AND can be meaningful. To
|
||
make sure that only lines are checked that actually have any TODO keyword
|
||
(resulting in a speed-up), use @kbd{C-c a M}, or equivalently start the TODO
|
||
part after the slash with @samp{!}. Using @kbd{C-c a M} or @samp{/!} will
|
||
not match TODO keywords in a DONE state. Examples:
|
||
|
||
@table @samp
|
||
@item work/WAITING
|
||
Same as @samp{work+TODO="WAITING"}
|
||
@item work/!-WAITING-NEXT
|
||
Select @samp{:work:}-tagged TODO lines that are neither @samp{WAITING}
|
||
nor @samp{NEXT}
|
||
@item work/!+WAITING|+NEXT
|
||
Select @samp{:work:}-tagged TODO lines that are either @samp{WAITING} or
|
||
@samp{NEXT}.

@cindex searching, for text
|
||
|

This agenda view is a general text search facility for Org mode entries.
|
||
It is particularly useful to find notes.
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c a s,org-search-view}
|
||
This is a special search that lets you select entries by matching a substring
|
||
or specific words using a boolean logic.
|
||
@end table
|
||
For example, the search string @samp{computer equipment} will find entries
|
||
that contain @samp{computer equipment} as a substring. If the two words are
|
||
separated by more space or a line break, the search will still match.
|
||
Search view can also search for specific keywords in the entry, using Boolean
|
||
logic. The search string @samp{+computer +wifi -ethernet -@{8\.11[bg]@}}
|
||
will search for note entries that contain the keywords @code{computer}
|
||
and @code{wifi}, but not the keyword @code{ethernet}, and which are also
|
||
not matched by the regular expression @code{8\.11[bg]}, meaning to

@pindex GTD, Getting Things Done
|
||
|
||
If you are following a system like David Allen's GTD to organize your
|
||
work, one of the ``duties'' you have is a regular review to make sure
|
||
that all projects move along. A @emph{stuck} project is a project that
|
||
has no defined next actions, so it will never show up in the TODO lists
|
||
Org mode produces. During the review, you need to identify such
|
||
projects and define next actions for them.
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c a #,org-agenda-list-stuck-projects}
|
||
List projects that are stuck.
|
||
@kindex C-c a !
|
||
@item C-c a !
|
||
@vindex org-stuck-projects
|
||
Customize the variable @code{org-stuck-projects} to define what a stuck
|
||
project is and how to find it.
|
||
@end table
|
||
|
||
You almost certainly will have to configure this view before it will
|
||
work for you. The built-in default assumes that all your projects are
|
||
level-2 headlines, and that a project is not stuck if it has at least
|
||
one entry marked with a TODO keyword TODO or NEXT or NEXTACTION.
|
||
|
||
Let's assume that you, in your own way of using Org mode, identify
|
||
projects with a tag PROJECT, and that you use a TODO keyword MAYBE to
|
||
indicate a project that should not be considered yet. Let's further
|
||
assume that the TODO keyword DONE marks finished projects, and that NEXT
|
||
and TODO indicate next actions. The tag @@SHOP indicates shopping and
|
||
is a next action even without the NEXT tag. Finally, if the project
|
||
contains the special word IGNORE anywhere, it should not be listed
|
||
either. In this case you would start by identifying eligible projects
|
||
with a tags/todo match@footnote{@xref{Tag searches}.}
|
||
@samp{+PROJECT/-MAYBE-DONE}, and then check for TODO, NEXT, @@SHOP, and
|
||
IGNORE in the subtree to identify projects that are not stuck. The
|
||
correct customization for this is
|
||
|
||
@lisp
|
||
(setq org-stuck-projects
|
||
'("+PROJECT/-MAYBE-DONE" ("NEXT" "TODO") ("@@SHOP")
|
||
"\\<IGNORE\\>"))
|
||
@end lisp
|
||
|
||
Note that if a project is identified as non-stuck, the subtree of this entry
|
||
will still be searched for stuck projects.

|

Before displaying items in an agenda view, Org mode visually prepares the
|
||
items and sorts them. Each item occupies a single line. The line starts
|
||
with a @emph{prefix} that contains the @emph{category} (@pxref{Categories})
|
||
of the item and other important information. You can customize in which
|
||
column tags will be displayed through @code{org-agenda-tags-column}. You can
|
||
also customize the prefix using the option @code{org-agenda-prefix-format}.
|
||
This prefix is followed by a cleaned-up version of the outline headline
|

associated with the item.

@cindex category
|

@cindex #+CATEGORY
|
||
The category is a broad label assigned to each agenda item. By default,
|
||
the category is simply derived from the file name, but you can also
|
||
specify it with a special line in the buffer, like this@footnote{For
|
||
backward compatibility, the following also works: if there are several
|
||
such lines in a file, each specifies the category for the text below it.
|
||
The first category also applies to any text before the first CATEGORY
|
||
line. However, using this method is @emph{strongly} deprecated as it is
|
||
incompatible with the outline structure of the document. The correct
|
||
method for setting multiple categories in a buffer is using a
|
||
property.}:
|
||
|
||
@example
|
||
#+CATEGORY: Thesis
|
||
@end example
|
||
|
||
@noindent
|
||
@cindex property, CATEGORY
|
||
If you would like to have a special CATEGORY for a single entry or a
|
||
(sub)tree, give the entry a @code{:CATEGORY:} property with the
|
||
special category you want to apply as the value.
|
||
|
||
@noindent
|
||
The display in the agenda buffer looks best if the category is not
|
||
longer than 10 characters.
|
||
|
||
@noindent
|
||
You can set up icons for category by customizing the
|
||
@code{org-agenda-category-icon-alist} variable.

|
||
@subsection Time-of-day specifications
|
||
@cindex time-of-day specification
|
||
|
||
Org mode checks each agenda item for a time-of-day specification. The
|
||
time can be part of the timestamp that triggered inclusion into the
|
||
agenda, for example as in @w{@samp{<2005-05-10 Tue 19:00>}}. Time
|
||
ranges can be specified with two timestamps, like
|
||
@c
|
||
@w{@samp{<2005-05-10 Tue 20:30>--<2005-05-10 Tue 22:15>}}.
|
||
|
||
In the headline of the entry itself, a time(range) may also appear as
|
||
plain text (like @samp{12:45} or a @samp{8:30-1pm}). If the agenda
|
||
integrates the Emacs diary (@pxref{Weekly/daily agenda}), time
|
||
specifications in diary entries are recognized as well.
|
||
|
||
For agenda display, Org mode extracts the time and displays it in a
|
||
standard 24 hour format as part of the prefix. The example times in
|
||
the previous paragraphs would end up in the agenda like this:
|
||
|
||
@example
|
||
8:30-13:00 Arthur Dent lies in front of the bulldozer
|
||
12:45...... Ford Prefect arrives and takes Arthur to the pub
|
||
19:00...... The Vogon reads his poem
|
||
20:30-22:15 Marvin escorts the Hitchhikers to the bridge
|
||
@end example
|
||
|
||
@cindex time grid
|
||
If the agenda is in single-day mode, or for the display of today, the
|
||
timed entries are embedded in a time grid, like
|
||
|
||
@example
|
||
8:00...... ------------------
|
||
8:30-13:00 Arthur Dent lies in front of the bulldozer
|
||
10:00...... ------------------
|
||
12:00...... ------------------
|
||
12:45...... Ford Prefect arrives and takes Arthur to the pub
|
||
14:00...... ------------------
|
||
16:00...... ------------------
|
||
18:00...... ------------------
|
||
19:00...... The Vogon reads his poem

done depends on the type of view.
|
||
@itemize @bullet
|
||
@item
|
||
@vindex org-agenda-files
|
||
For the daily/weekly agenda, the items for each day are sorted. The
|
||
default order is to first collect all items containing an explicit
|
||
time-of-day specification. These entries will be shown at the beginning
|
||
of the list, as a @emph{schedule} for the day. After that, items remain
|
||
grouped in categories, in the sequence given by @code{org-agenda-files}.
|
||
Within each category, items are sorted by priority (@pxref{Priorities}),
|
||
which is composed of the base priority (2000 for priority @samp{A}, 1000
|
||
for @samp{B}, and 0 for @samp{C}), plus additional increments for
|
||
overdue scheduled or deadline items.
|
||
@item
|
||
For the TODO list, items remain in the order of categories, but within
|
||
each category, sorting takes place according to priority
|
||
(@pxref{Priorities}). The priority used for sorting derives from the
|
||
priority cookie, with additions depending on how close an item is to its due
|
||
or scheduled date.
|
||
@item
|

Entries in the agenda buffer are linked back to the Org file or diary
|
||
file where they originate. You are not allowed to edit the agenda
|
||
buffer itself, but commands are provided to show and jump to the
|
||
original entry location, and to edit the Org files ``remotely'' from
|
||
the agenda buffer. In this way, all information is stored only once,
|
||
removing the risk that your agenda and note files may diverge.
|
||
|
||
Some commands can be executed with mouse clicks on agenda lines. For
|
||
the other commands, the cursor needs to be in the desired line.

Switch to day/week/month/year view. When switching to day or week view, this

||
setting becomes the default for subsequent agenda refreshes. Since month and
|
||
year views are slow to create, they do not become the default. A numeric
|
||
prefix argument may be used to jump directly to a specific day of the year,
|
||
ISO week, month, or year, respectively. For example, @kbd{32 d} jumps to
|
||
February 1st, @kbd{9 w} to ISO week number 9. When setting day, week, or
|
||
month view, a year may be encoded in the prefix argument as well. For
|
||
example, @kbd{200712 w} will jump to week 12 in 2007. If such a year
|
||
specification has only one or two digits, it will be mapped to the interval

1938-2037. @kbd{v @key{SPC}} will reset to what is set in

The difference between this and a custom agenda command is that filtering is
|
||
very fast, so that you can switch quickly between different filters without
|
||
having to recreate the agenda.@footnote{Custom commands can preset a filter by
|
||
binding the variable @code{org-agenda-tag-filter-preset} as an option. This
|
||
filter will then be applied to the view and persist as a basic filter through
|
||
refreshes and more secondary filtering. The filter is a global property of
|
||
the entire agenda view---in a block agenda, you should only set this in the
|
||
global options section, not in the section of an individual block.}
|
||
|
||
You will be prompted for a tag selection letter; @key{SPC} will mean any tag at
|
||
all. Pressing @key{TAB} at that prompt will offer use completion to select a
|
||
tag (including any tags that do not have a selection character). The command
|
||
then hides all entries that do not contain or inherit this tag. When called
|
||
with prefix arg, remove the entries that @emph{do} have the tag. A second
|
||
@kbd{/} at the prompt will turn off the filter and unhide any hidden entries.
|
||
If the first key you press is either @kbd{+} or @kbd{-}, the previous filter
|
||
will be narrowed by requiring or forbidding the selected additional tag.
|

Instead of pressing @kbd{+} or @kbd{-} after @kbd{/}, you can also

|
||
You can then filter for an effort by first typing an operator, one of
|
||
@kbd{<}, @kbd{>}, and @kbd{=}, and then the one-digit index of an effort
|
||
estimate in your array of allowed values, where @kbd{0} means the 10th value.
|
||
The filter will then restrict to entries with effort smaller-or-equal, equal,
|
||
or larger-or-equal than the selected value. If the digits 0-9 are not used
|
||
as fast access keys to tags, you can also simply press the index digit
|
||
directly without an operator. In this case, @kbd{<} will be assumed. For
|
||
application of the operator, entries without a defined effort will be treated
|
||
according to the value of @code{org-sort-agenda-noeffort-is-high}. To filter
|
||
for tasks without effort definition, press @kbd{?} as the operator.
|
||
|
||
Org also supports automatic, context-aware tag filtering. If the variable
|
||
@code{org-agenda-auto-exclude-function} is set to a user-defined function,
|
||
that function can decide which tags should be excluded from the agenda
|
||
automatically. Once this is set, the @kbd{/} command then accepts @kbd{RET}
|
||
as a sub-option key and runs the auto exclusion logic. For example, let's
|
||
say you use a @code{Net} tag to identify tasks which need network access, an
|
||
@code{Errand} tag for errands in town, and a @code{Call} tag for making phone
|
||
calls. You could auto-exclude these tags based on the availability of the
|
||
Internet, and outside of business hours, with something like this:
|
||
|
||
@lisp
|
||
@group
|
||
(defun org-my-auto-exclude-function (tag)
|
||
(and (cond
|
||
((string= tag "Net")
|
||
(/= 0 (call-process "/sbin/ping" nil nil nil
|
||
"-c1" "-q" "-t1" "mail.gnu.org")))
|
||
((or (string= tag "Errand") (string= tag "Call"))
|
||
(let ((hour (nth 2 (decode-time))))
|
||
(or (< hour 8) (> hour 21)))))
|
||
(concat "-" tag)))

|

@end group

@end lisp

@orgcmd{\\,org-agenda-filter-by-tag-refine}
|
||
Narrow the current agenda filter by an additional condition. When called with
|
||
prefix arg, remove the entries that @emph{do} have the tag, or that do match
|
||
the effort criterion. You can achieve the same effect by pressing @kbd{+} or
|
||
@kbd{-} as the first key after the @kbd{/} command.

Change the timestamp associated with the current line by one day into the
|
||
future. If the date is in the past, the first call to this command will move
|
||
it to today.@*
|
||
With a numeric prefix argument, change it by that many days. For example,
|
||
@kbd{3 6 5 S-@key{right}} will change it by a year. With a @kbd{C-u} prefix,
|
||
change the time by one hour. If you immediately repeat the command, it will
|
||
continue to change hours even without the prefix arg. With a double @kbd{C-u
|
||
C-u} prefix, do the same for changing minutes.@*
|
||
The stamp is changed in the original Org file, but the change is not directly
|
||
reflected in the agenda buffer. Use @kbd{r} or @kbd{g} to update the buffer.
|

@vindex org-agenda-diary-file
|

block entries) the date at the mark. This will add to the Emacs diary
|
||
file@footnote{This file is parsed for the agenda when
|

command in the calendar. The diary file will pop up in another window, where
|
||
you can add the entry.
|
||
|
||
If you configure @code{org-agenda-diary-file} to point to an Org mode file,
|
||
Org will create entries (in Org mode syntax) in that file instead. Most
|
||
entries will be stored in a date-based outline tree that will later make it
|
||
easy to archive appointments from previous months/years. The tree will be
|
||
built under an entry with a @code{DATE_TREE} property, or else with years as
|
||
top-level entries. Emacs will prompt you for the entry text---if you specify
|
||
it, the entry will be created in @code{org-agenda-diary-file} without further
|
||
interaction. If you directly press @key{RET} at the prompt without typing
|
||
text, the target file will be shown in another window for you to finish the
|

Custom agenda commands serve two purposes: to store and quickly access

@subsection Storing searches
|
||
|
||
The first application of custom searches is the definition of keyboard
|
||
shortcuts for frequently used searches, either creating an agenda
|
||
buffer, or a sparse tree (the latter covering of course only the current
|
||
buffer).
|
||
@kindex C-c a C
|
||
@vindex org-agenda-custom-commands
|
||
Custom commands are configured in the variable
|
||
@code{org-agenda-custom-commands}. You can customize this variable, for
|
||
example by pressing @kbd{C-c a C}. You can also directly set it with
|
||
Emacs Lisp in @file{.emacs}. The following example contains all valid
|
||
search types:
|
||
|
||
@lisp
|
||
@group
|
||
(setq org-agenda-custom-commands
|
||
'(("w" todo "WAITING")
|
||
("W" todo-tree "WAITING")
|
||
("u" tags "+boss-urgent")
|
||
("v" tags-todo "+boss-urgent")
|
||
("U" tags-tree "+boss-urgent")
|
||
("f" occur-tree "\\<FIXME\\>")
|
||
("h" . "HOME+Name tags searches") ; description for "h" prefix
|
||
("hl" tags "+home+Lisa")
|
||
("hp" tags "+home+Peter")
|
||
("hk" tags "+home+Kim")))
|
||
@end group
|
||
@end lisp
|
||
|
||
@noindent
|
||
The initial string in each entry defines the keys you have to press
|
||
after the dispatcher command @kbd{C-c a} in order to access the command.
|
||
Usually this will be just a single character, but if you have many
|
||
similar commands, you can also define two-letter combinations where the
|
||
first character is the same in several combinations and serves as a
|
||
prefix key@footnote{You can provide a description for a prefix key by
|
||
inserting a cons cell with the prefix and the description.}. The second
|
||
parameter is the search type, followed by the string or regular
|
||
expression to be used for the matching. The example above will
|
||
therefore define:
|
||
|
||
@table @kbd
|
||
@item C-c a w
|
||
as a global search for TODO entries with @samp{WAITING} as the TODO
|
||
keyword
|
||
@item C-c a W
|
||
as the same search, but only in the current buffer and displaying the
|
||
results as a sparse tree
|
||
@item C-c a u
|
||
as a global tags search for headlines marked @samp{:boss:} but not
|
||
@samp{:urgent:}
|
||
@item C-c a v
|
||
as the same search as @kbd{C-c a u}, but limiting the search to
|
||
headlines that are also TODO items
|
||
@item C-c a U
|
||
as the same search as @kbd{C-c a u}, but only in the current buffer and
|
||
displaying the result as a sparse tree
|
||
@item C-c a f
|
||
to create a sparse tree (again: current buffer only) with all entries
|
||
containing the word @samp{FIXME}
|
||
@item C-c a h
|
||
as a prefix command for a HOME tags search where you have to press an
|
||
additional key (@kbd{l}, @kbd{p} or @kbd{k}) to select a name (Lisa,
|
||
Peter, or Kim) as additional tag to match.

@subsection Block agenda
|

@cindex block agenda
|
||
@cindex agenda, with block views
|
||
|
||
Another possibility is the construction of agenda views that comprise
|
||
the results of @emph{several} commands, each of which creates a block in
|
||
the agenda buffer. The available commands include @code{agenda} for the
|
||
daily or weekly agenda (as created with @kbd{C-c a a}), @code{alltodo}
|
||
for the global TODO list (as constructed with @kbd{C-c a t}), and the
|
||
matching commands discussed above: @code{todo}, @code{tags}, and
|
||
@code{tags-todo}. Here are two examples:
|
||
|
||
@lisp
|
||
@group
|
||
(setq org-agenda-custom-commands
|
||
'(("h" "Agenda and Home-related tasks"
|
||
((agenda "")
|
||
(tags-todo "home")
|
||
(tags "garden")))
|
||
("o" "Agenda and Office-related tasks"
|
||
((agenda "")
|
||
(tags-todo "work")
|
||
(tags "office")))))
|
||
@end group
|
||
@end lisp
|
||
|
||
@noindent
|
||
This will define @kbd{C-c a h} to create a multi-block view for stuff
|
||
you need to attend to at home. The resulting agenda buffer will contain
|
||
your agenda for the current week, all TODO items that carry the tag
|
||
@samp{home}, and also all lines tagged with @samp{garden}. Finally the
|
||
command @kbd{C-c a o} provides a similar view for office tasks.
|
||
|
||
@node Setting Options, , Block agenda, Custom agenda views
|
||
@subsection Setting options for custom commands
|
||
@cindex options, for custom agenda views
|
||
|
||
@vindex org-agenda-custom-commands
|
||
Org mode contains a number of variables regulating agenda construction
|
||
and display. The global variables define the behavior for all agenda
|
||
commands, including the custom commands. However, if you want to change
|
||
some settings just for a single custom view, you can do so. Setting
|
||
options requires inserting a list of variable names and values at the
|
||
right spot in @code{org-agenda-custom-commands}. For example:
|
||
|
||
@lisp
|
||
@group
|
||
(setq org-agenda-custom-commands
|
||
'(("w" todo "WAITING"
|
||
((org-agenda-sorting-strategy '(priority-down))
|
||
(org-agenda-prefix-format " Mixed: ")))
|
||
("U" tags-tree "+boss-urgent"
|
||
((org-show-following-heading nil)
|
||
(org-show-hierarchy-above nil)))
|
||
("N" search ""
|
||
((org-agenda-files '("~org/notes.org"))
|
||
(org-agenda-text-search-extra-files nil)))))
|
||
@end group
|
||
@end lisp
|
||
|
||
@noindent
|
||
Now the @kbd{C-c a w} command will sort the collected entries only by
|
||
priority, and the prefix format is modified to just say @samp{ Mixed: }
|
||
instead of giving the category of the entry. The sparse tags tree of
|
||
@kbd{C-c a U} will now turn out ultra-compact, because neither the
|
||
headline hierarchy above the match, nor the headline following the match
|
||
will be shown. The command @kbd{C-c a N} will do a text search limited
|
||
to only a single file.
|
||
|
||
@vindex org-agenda-custom-commands
|
||
For command sets creating a block agenda,
|
||
@code{org-agenda-custom-commands} has two separate spots for setting
|
||
options. You can add options that should be valid for just a single
|
||
command in the set, and options that should be valid for all commands in
|
||
the set. The former are just added to the command entry; the latter
|
||
must come after the list of command entries. Going back to the block
|
||
agenda example (@pxref{Block agenda}), let's change the sorting strategy
|
||
for the @kbd{C-c a h} commands to @code{priority-down}, but let's sort
|
||
the results for GARDEN tags query in the opposite order,
|
||
@code{priority-up}. This would look like this:
|
||
|
||
@lisp
|
||
@group
|
||
(setq org-agenda-custom-commands
|
||
'(("h" "Agenda and Home-related tasks"
|
||
((agenda)
|
||
(tags-todo "home")
|
||
(tags "garden"
|
||
((org-agenda-sorting-strategy '(priority-up)))))
|
||
((org-agenda-sorting-strategy '(priority-down))))
|
||
("o" "Agenda and Office-related tasks"
|
||
((agenda)
|
||
(tags-todo "work")
|
||
(tags "office")))))
|
||
@end group
|
||
@end lisp
|
||
|
||
As you see, the values and parentheses setting is a little complex.
|
||
When in doubt, use the customize interface to set this variable---it
|
||
fully supports its structure. Just one caveat: when setting options in
|
||
this interface, the @emph{values} are just Lisp expressions. So if the
|
||
value is a string, you need to add the double-quotes around the value
|
||
yourself.

@cindex agenda views, exporting
|
||
|
||
If you are away from your computer, it can be very useful to have a printed
|
||
version of some agenda views to carry around. Org mode can export custom
|
||
agenda views as plain text, HTML@footnote{You need to install Hrvoje Niksic's
|
||
@file{htmlize.el}.}, Postscript, PDF@footnote{To create PDF output, the
|
||
ghostscript @file{ps2pdf} utility must be installed on the system. Selecting
|
||
a PDF file will also create the postscript file.}, and iCalendar files. If
|
||
you want to do this only occasionally, use the command
|
||
|
||
@table @kbd
|
||
@orgcmd{C-x C-w,org-write-agenda}
|
||
@cindex exporting agenda views
|
||
@cindex agenda views, exporting
|
||
@vindex org-agenda-exporter-settings
|
||
Write the agenda view to a file. Depending on the extension of the selected
|
||
file name, the view will be exported as HTML (extension @file{.html} or
|
||
@file{.htm}), Postscript (extension @file{.ps}), iCalendar (extension
|
||
@file{.ics}), or plain text (any other extension). Use the variable
|
||
@code{org-agenda-exporter-settings} to set options for @file{ps-print} and
|
||
for @file{htmlize} to be used during export, for example
|
||
|
||
@vindex org-agenda-add-entry-text-maxlines
|
||
@vindex htmlize-output-type
|
||
@vindex ps-number-of-columns
|
||
@vindex ps-landscape-mode
|
||
@lisp
|
||
(setq org-agenda-exporter-settings

|
||
(htmlize-output-type 'css)))
|
||
@end lisp
|
||
@end table
|
||
|
||
If you need to export certain agenda views frequently, you can associate
|
||
any custom agenda command with a list of output file names
|
||
@footnote{If you want to store standard views like the weekly agenda
|
||
or the global TODO list as well, you need to define custom commands for
|
||
them in order to be able to specify file names.}. Here is an example
|
||
that first defines custom commands for the agenda and the global
|
||
TODO list, together with a number of files to which to export them.
|
||
Then we define two block agenda commands and specify file names for them
|
||
as well. File names can be relative to the current working directory,
|
||
or absolute.
|
||
|
||
@lisp
|
||
@group
|
||
(setq org-agenda-custom-commands
|
||
'(("X" agenda "" nil ("agenda.html" "agenda.ps"))

("~/views/office.ps" "~/calendars/office.ics"))))
|
||
@end group
|
||
@end lisp
|
||
|
||
The extension of the file name determines the type of export. If it is
|
||
@file{.html}, Org mode will use the @file{htmlize.el} package to convert
|
||
the buffer to HTML and save it to this file name. If the extension is
|
||
@file{.ps}, @code{ps-print-buffer-with-faces} is used to produce
|
||
Postscript output. If the extension is @file{.ics}, iCalendar export is
|
||
run export over all files that were used to construct the agenda, and
|
||
limit the export to entries listed in the agenda. Any other
|
||
extension produces a plain ASCII file.
|
||
|
||
The export files are @emph{not} created when you use one of those
|
||
commands interactively because this might use too much overhead.
|
||
Instead, there is a special command to produce @emph{all} specified
|
||
files in one step:
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c a e,org-store-agenda-views}
|
||
Export all agenda views that have export file names associated with
|
||
them.
|
||
@end table
|
||
|
||
You can use the options section of the custom agenda commands to also
|
||
set options for the export commands. For example:
|
||
|
||
@lisp
|
||
(setq org-agenda-custom-commands
|
||
'(("X" agenda ""
|
||
((ps-number-of-columns 2)
|
||
(ps-landscape-mode t)
|
||
(org-agenda-prefix-format " [ ] ")
|
||
(org-agenda-with-colors nil)
|
||
(org-agenda-remove-tags t))
|
||
("theagenda.ps"))))
|
||
@end lisp
|
||
|
||
@noindent
|
||
This command sets two options for the Postscript exporter, to make it
|
||
print in two columns in landscape format---the resulting page can be cut
|
||
in two and then used in a paper agenda. The remaining settings modify
|
||
the agenda prefix to omit category and scheduling information, and
|
||
instead include a checkbox to check off items. We also remove the tags
|
||
to make the lines compact, and we don't want to use colors for the
|
||
black-and-white printer. Settings specified in
|
||
@code{org-agenda-exporter-settings} will also apply, but the settings
|
||
in @code{org-agenda-custom-commands} take precedence.
|
||
|
||
@noindent
|
||
From the command line you may also use
|
||
@example
|
||
emacs -eval (org-batch-store-agenda-views) -kill
|
||
@end example
|
||
@noindent
|
||
or, if you need to modify some parameters@footnote{Quoting depends on the
|
||
system you use, please check the FAQ for examples.}
|
||
@example
|
||
emacs -eval '(org-batch-store-agenda-views \
|
||
org-agenda-span (quote month) \
|
||
org-agenda-start-day "2007-11-01" \
|
||
org-agenda-include-diary nil \
|
||
org-agenda-files (quote ("~/org/project.org")))' \
|
||
-kill
|
||
@end example
|
||
@noindent
|
||
which will create the agenda views restricted to the file
|
||
@file{~/org/project.org}, without diary entries and with a 30-day
|
||
extent.
|
||
|
||
You can also extract agenda information in a way that allows further
|
||
processing by other programs. See @ref{Extracting agenda information}, for
|

more information.

@section Using column view in the agenda
|

@cindex column view, in agenda
|
||
@cindex agenda, column view
|
||
|
||
Column view (@pxref{Column view}) is normally used to view and edit
|
||
properties embedded in the hierarchical structure of an Org file. It can be
|
||
quite useful to use column view also from the agenda, where entries are
|
||
collected by certain criteria.
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-x C-c,org-agenda-columns}
|
||
Turn on column view in the agenda.
|
||
@end table
|
||
|
||
To understand how to use this properly, it is important to realize that the
|
||
entries in the agenda are no longer in their proper outline environment.
|
||
This causes the following issues:
|
||
|
||
@enumerate
|
||
@item
|
||
@vindex org-columns-default-format
|
||
@vindex org-overriding-columns-format
|
||
Org needs to make a decision which @code{COLUMNS} format to use. Since the
|
||
entries in the agenda are collected from different files, and different files
|
||
may have different @code{COLUMNS} formats, this is a non-trivial problem.
|
||
Org first checks if the variable @code{org-agenda-overriding-columns-format} is
|
||
currently set, and if so, takes the format from there. Otherwise it takes
|
||
the format associated with the first item in the agenda, or, if that item
|
||
does not have a specific format (defined in a property, or in its file), it
|
||
uses @code{org-columns-default-format}.
|
||
@item
|
||
@cindex property, special, CLOCKSUM
|
||
If any of the columns has a summary type defined (@pxref{Column attributes}),
|
||
turning on column view in the agenda will visit all relevant agenda files and
|
||
make sure that the computations of this property are up to date. This is
|
||
also true for the special @code{CLOCKSUM} property. Org will then sum the
|
||
values displayed in the agenda. In the daily/weekly agenda, the sums will
|
||
cover a single day; in all other views they cover the entire block. It is
|
||
vital to realize that the agenda may show the same entry @emph{twice} (for
|
||
example as scheduled and as a deadline), and it may show two entries from the
|
||
same hierarchy (for example a @emph{parent} and its @emph{child}). In these
|
||
cases, the summation in the agenda will lead to incorrect results because
|
||
some values will count double.
|
||
@item
|
||
When the column view in the agenda shows the @code{CLOCKSUM}, that is always
|
||
the entire clocked time for this item. So even in the daily/weekly agenda,
|
||
the clocksum listed in column view may originate from times outside the
|
||
current view. This has the advantage that you can compare these values with
|
||
a column listing the planned total effort for a task---one of the major
|
||
applications for column view in the agenda. If you want information about
|
||
clocked time in the displayed period use clock table mode (press @kbd{R} in
|
||
the agenda).

@chapter Markup for rich export

When exporting Org mode documents, the exporter tries to reflect the

export targets like HTML, @LaTeX{}, or DocBook allow much richer formatting,

@example
|
||
#+TITLE: This is the title of the document

If this line does not exist, the title is derived from the first non-empty,

turned off exporting of the text before the first headline (see below), the
|

title will be the file name without extension.
|
||
|
||
@cindex property, EXPORT_TITLE
|
||
If you are exporting only a subtree by marking is as the region, the heading

@vindex org-export-headline-levels
|

The outline structure of the document as described in @ref{Document

|
||
However, since the outline structure is also used for (for example) lists of
|
||
tasks, only the first three outline levels will be used as headings. Deeper
|
||
levels will become itemized lists. You can change the location of this
|
||
switch globally by setting the variable @code{org-export-headline-levels}, or on a
|
||
per-file basis with a line
|

@vindex org-export-with-toc
|
||
The table of contents is normally inserted directly before the first headline
|
||
of the file. If you would like to get it to a different location, insert the
|
||
string @code{[TABLE-OF-CONTENTS]} on a line by itself at the desired
|
||
location. The depth of the table of contents is by default the same as the
|
||
number of headline levels, but you can choose a smaller number, or turn off
|
||
the table of contents entirely, by configuring the variable
|
||
@code{org-export-with-toc}, or on a per-file basis with a line like
|
||
|
||
@example
|
||
#+OPTIONS: toc:2 (only to two levels in TOC)

@cindex #+TEXT
|
||
|
||
Org mode normally exports the text before the first headline, and even uses
|
||
the first line as the document title. The text will be fully marked up. If
|
||
you need to include literal HTML, @LaTeX{}, or DocBook code, use the special
|
||
constructs described below in the sections for the individual exporters.
|
||
|
||
@vindex org-export-skip-text-before-1st-heading
|
||
Some people like to use the space before the first headline for setup and
|
||
internal links and therefore would like to control the exported text before
|
||
the first headline in a different way. You can do so by setting the variable
|
||
@code{org-export-skip-text-before-1st-heading} to @code{t}. On a per-file
|
||
basis, you can get the same effect with @samp{#+OPTIONS: skip:t}.
|
||
|
||
@noindent
|
||
If you still want to have some text before the first headline, use the
|
||
@code{#+TEXT} construct:
|
||
|
||
@example
|
||
#+OPTIONS: skip:t
|
||
#+TEXT: This text will go before the *first* headline.
|
||
#+TEXT: [TABLE-OF-CONTENTS]
|
||
#+TEXT: This goes between the table of contents and the *first* headline

Both the native Org mode tables (@pxref{Tables}) and tables formatted with

the @file{table.el} package will be exported properly. For Org mode tables,
|
||
the lines before the first horizontal separator line will become table header
|
||
lines. You can use the following lines somewhere before the table to assign
|
||
a caption and a label for cross references, and in the text you can refer to
|
||
the object with @code{\ref@{tab:basic-data@}}:
|
||
|
||
@example
|

#+CAPTION: This is the caption for the next table (or link)

#+LABEL: tbl:basic-data
|

Some backends (HTML, @LaTeX{}, and DocBook) allow you to directly include
|

images into the exported document. Org does this, if a link to an image
|
||
files does not have a description part, for example @code{[[./img/a.jpg]]}.
|
||
If you wish to define a caption for the image and maybe a label for internal
|
||
cross references, make sure that the link is on a line by itself and precede
|
||
it with @code{#+CAPTION} and @code{#+LABEL} as follows:
|
||
|
||
@example
|
||
#+CAPTION: This is the caption for the next figure link (or table)
|

#+LABEL: fig:SED-HR4049
|

[[./img/a.jpg]]
|

@cindex formatting source code, markup rules
|
||
If the example is source code from a programming language, or any other text
|
||
that can be marked up by font-lock in Emacs, you can ask for the example to
|
||
look like the fontified Emacs buffer@footnote{This works automatically for
|
||
the HTML backend (it requires version 1.34 of the @file{htmlize.el} package,
|
||
which is distributed with Org). Fontified code chunks in @LaTeX{} can be
|
||
achieved using either the listings or the
|
||
@url{http://code.google.com/p/minted, minted,} package. To use listings, turn
|
||
on the variable @code{org-export-latex-listings} and ensure that the listings
|
||
package is included by the @LaTeX{} header (e.g.@: by configuring
|
||
@code{org-export-latex-packages-alist}). See the listings documentation for
|
||
configuration options, including obtaining colored output. For minted it is
|
||
necessary to install the program @url{http://pygments.org, pygments}, in
|
||
addition to setting @code{org-export-latex-minted}, ensuring that the minted
|
||
package is included by the @LaTeX{} header, and ensuring that the
|
||
@code{-shell-escape} option is passed to @file{pdflatex} (see
|
||
@code{org-latex-to-pdf-process}). See the documentation of the variables
|
||
@code{org-export-latex-listings} and @code{org-export-latex-minted} for
|
||
further details.}. This is done with the @samp{src} block, where you also
|
||
need to specify the name of the major mode that should be used to fontify the
|
||
example@footnote{Code in @samp{src} blocks may also be evaluated either
|
||
interactively or on export. See @pxref{Working With Source Code} for more
|
||
information on evaluating code blocks.}, see @ref{Easy Templates} for
|
||
shortcuts to easily insert code blocks.
|

@cindex #+BEGIN_SRC
|
||
|

@example
|
||
#+BEGIN_SRC emacs-lisp
|

(defun org-xor (a b)
|
||
"Exclusive or."
|
||
(if a (not b) b))
|
||
#+END_SRC
|
||
@end example
|
||
|
||
Both in @code{example} and in @code{src} snippets, you can add a @code{-n}
|
||
switch to the end of the @code{BEGIN} line, to get the lines of the example
|
||
numbered. If you use a @code{+n} switch, the numbering from the previous
|
||
numbered snippet will be continued in the current one. In literal examples,
|
||
Org will interpret strings like @samp{(ref:name)} as labels, and use them as
|
||
targets for special hyperlinks like @code{[[(name)]]} (i.e.@: the reference name
|
||
enclosed in single parenthesis). In HTML, hovering the mouse over such a
|
||
link will remote-highlight the corresponding code line, which is kind of
|
||
cool.
|
||
|
||
You can also add a @code{-r} switch which @i{removes} the labels from the
|
||
source code@footnote{Adding @code{-k} to @code{-n -r} will @i{keep} the
|
||
labels in the source code while using line numbers for the links, which might
|
||
be useful to explain those in an Org mode example code.}. With the @code{-n}
|
||
switch, links to these references will be labeled by the line numbers from
|
||
the code listing, otherwise links will use the labels with no parentheses.
|
||
Here is an example:
|
||
|
||
@example
|
||
#+BEGIN_SRC emacs-lisp -n -r
|
||
(save-excursion (ref:sc)
|
||
(goto-char (point-min)) (ref:jump)
|
||
#+END_SRC
|
||
In line [[(sc)]] we remember the current position. [[(jump)][Line (jump)]]
|
||
jumps to point-min.
|
||
@end example
|
||
|
||
@vindex org-coderef-label-format
|
||
If the syntax for the label format conflicts with the language syntax, use a
|
||
@code{-l} switch to change the format, for example @samp{#+BEGIN_SRC pascal
|
||
-n -r -l "((%s))"}. See also the variable @code{org-coderef-label-format}.
|
||
|
||
HTML export also allows examples to be published as text areas (@pxref{Text
|
||

|
||
|
||
Because the @code{#+BEGIN_...} and @code{#+END_...} patterns need to be added
|

Edit the source code example at point in its native mode. This works by

switching to a temporary buffer with the source code. You need to exit by

pressing @kbd{C-c '} again@footnote{Upon exit, lines starting with @samp{*}
|

or @samp{#} will get a comma prepended, to keep them from being interpreted
|
||
by Org as outline nodes or special comments. These commas will be stripped
|
||
for editing with @kbd{C-c '}, and also for export.}. The edited version will
|
||
then replace the old version in the Org buffer. Fixed-width regions
|
||
(where each line starts with a colon followed by a space) will be edited
|
||
using @code{artist-mode}@footnote{You may select a different-mode with the
|
||
variable @code{org-edit-fixed-width-region-mode}.} to allow creating ASCII

@kindex C-c l
|

@item C-c l
|

Calling @code{org-store-link} while editing a source code example in a

temporary buffer created with @kbd{C-c '} will prompt for a label. Make sure
|
||
that it is unique in the current buffer, and insert it with the proper

label is stored as a link @samp{(label)}, for retrieval with @kbd{C-c C-l}.

language for formatting the contents. The markup is optional; if it is not

given, the text will be assumed to be in Org mode format and will be

processed normally. The include line will also allow additional keyword
|

parameters @code{:prefix1} and @code{:prefix} to specify prefixes for the
|
||
first line and for each following line, @code{:minlevel} in order to get
|
||
Org mode content demoted to a specified level, as well as any options

use

You can also include a portion of a file by specifying a lines range using

the @code{:lines} parameter. The line at the upper end of the range will not

You can use @LaTeX{} macros to insert special symbols like @samp{\alpha} to

indicate the Greek letter, or @samp{\to} to indicate an arrow. Completion
|
||
for these macros is available, just type @samp{\} and maybe a few letters,
|
||
and press @kbd{M-@key{TAB}} to see possible completions. Unlike @LaTeX{}
|
||
code, Org mode allows these macros to be present without surrounding math
|
||
delimiters, for example:
|
||
|
||
@example
|
||
Angles are written as Greek letters \alpha, \beta and \gamma.
|
||
@end example
|
||
|
||
@vindex org-entities
|
||
During export, these symbols will be transformed into the native format of
|
||
the exporter backend. Strings like @code{\alpha} will be exported as
|
||
@code{α} in the HTML output, and as @code{$\alpha$} in the @LaTeX{}
|
||
output. Similarly, @code{\nbsp} will become @code{ } in HTML and
|
||
@code{~} in @LaTeX{}. If you need such a symbol inside a word, terminate it
|
||
like this: @samp{\Aacute@{@}stor}.
|
||
|
||
A large number of entities is provided, with names taken from both HTML and
|
||
@LaTeX{}; see the variable @code{org-entities} for the complete list.
|
||
@samp{\-} is treated as a shy hyphen, and @samp{--}, @samp{---}, and
|
||
@samp{...} are all converted into special commands creating hyphens of
|
||
different lengths or a compact set of dots.
|
||
|
||
If you would like to see entities displayed as UTF8 characters, use the
|
||
following command@footnote{You can turn this on by default by setting the
|

Just like in @LaTeX{}, @samp{^} and @samp{_} are used to indicate super-

math-mode delimiters. To increase the readability of ASCII text, it is
|
||
not necessary (but OK) to surround multi-character sub- and superscripts
|
||
with curly braces. For example

||
|
||
@example
|
||
The mass of the sun is M_sun = 1.989 x 10^30 kg. The radius of

the sun is R_@{sun@} = 6.96 x 10^8 m.

@vindex org-format-latex-header
|

Going beyond symbols and sub- and superscripts, a full formula language is
|
||
needed. Org mode can contain @LaTeX{} math fragments, and it supports ways
|
||
to process these for several export backends. When exporting to @LaTeX{},
|
||
the code is obviously left as it is. When exporting to HTML, Org invokes the
|
||
@uref{http://www.mathjax.org, MathJax library} (@pxref{Math formatting in
|
||
HTML export}) to process and display the math@footnote{If you plan to use
|
||
this regularly or on pages with significant page views, you should install
|
||
@file{MathJax} on your own
|
||
server in order to limit the load of our server.}. Finally, it can also
|
||
process the mathematical expressions into images@footnote{For this to work
|
||
you need to be on a system with a working @LaTeX{} installation. You also
|
||
need the @file{dvipng} program, available at
|
||
@url{http://sourceforge.net/projects/dvipng/}. The @LaTeX{} header that will
|
||
be used when processing a fragment can be configured with the variable
|
||
@code{org-format-latex-header}.} that can be displayed in a browser or in
|
||
DocBook documents.
|
||
|
||
@LaTeX{} fragments don't need any special marking at all. The following
|
||
snippets will be identified as @LaTeX{} source code:
|
||
@itemize @bullet
|
||
@item
|
||
Environments of any kind@footnote{When @file{MathJax} is used, only the
|
||
environment recognized by @file{MathJax} will be processed. When
|
||
@file{dvipng} is used to create images, any @LaTeX{} environments will be
|
||
handled.}. The only requirement is that the @code{\begin} statement appears
|
||
on a new line, preceded by only whitespace.
|
||
@item
|
||
Text within the usual @LaTeX{} math delimiters. To avoid conflicts with
|
||
currency specifications, single @samp{$} characters are only recognized as
|
||
math delimiters if the enclosed text contains at most two line breaks, is
|
||
directly attached to the @samp{$} characters with no whitespace in between,
|
||
and if the closing @samp{$} is followed by whitespace, punctuation or a dash.
|
||
For the other delimiters, there is no such restriction, so when in doubt, use
|
||
@samp{\(...\)} as inline math delimiters.

@cindex @LaTeX{} fragments, preview
|
||
|
||
If you have @file{dvipng} installed, @LaTeX{} fragments can be processed to
|
||
produce preview images of the typeset expressions:
|
||
|
||
@table @kbd
|
||
@kindex C-c C-x C-l
|
||
@item C-c C-x C-l
|
||
Produce a preview image of the @LaTeX{} fragment at point and overlay it
|
||
over the source code. If there is no fragment at point, process all
|
||
fragments in the current entry (between two headlines). When called
|
||
with a prefix argument, process the entire subtree. When called with
|
||
two prefix arguments, or when the cursor is before the first headline,
|
||
process the entire buffer.
|
||
@kindex C-c C-c
|
||
@item C-c C-c
|
||
Remove the overlay preview images.
|
||
@end table
|
||
|
||
@vindex org-format-latex-options
|
||
You can customize the variable @code{org-format-latex-options} to influence
|
||
some aspects of the preview. In particular, the @code{:scale} (and for HTML
|
||
export, @code{:html-scale}) property can be used to adjust the size of the
|
||
preview images.

@subsection Using CD@LaTeX{} to enter math
|
||
@cindex CD@LaTeX{}
|
||
|
||
CD@LaTeX{} mode is a minor mode that is normally used in combination with a
|
||
major @LaTeX{} mode like AUC@TeX{} in order to speed-up insertion of
|
||
environments and math templates. Inside Org mode, you can make use of
|
||
some of the features of CD@LaTeX{} mode. You need to install
|
||
@file{cdlatex.el} and @file{texmathp.el} (the latter comes also with
|
||
AUC@TeX{}) from @url{http://www.astro.uva.nl/~dominik/Tools/cdlatex}.
|
||
Don't use CD@LaTeX{} mode itself under Org mode, but use the light
|
||
version @code{org-cdlatex-mode} that comes as part of Org mode. Turn it
|
||
on for the current buffer with @code{M-x org-cdlatex-mode}, or for all
|
||
Org files with
|
||
|
||
@lisp
|
||
(add-hook 'org-mode-hook 'turn-on-org-cdlatex)
|
||
@end lisp
|
||
|
||
When this mode is enabled, the following features are present (for more
|
||
details see the documentation of CD@LaTeX{} mode):
|
||
@itemize @bullet
|
||
@kindex C-c @{
|
||
@item
|
||
Environment templates can be inserted with @kbd{C-c @{}.
|
||
@item
|
||
@kindex @key{TAB}
|
||
The @key{TAB} key will do template expansion if the cursor is inside a
|
||
@LaTeX{} fragment@footnote{Org mode has a method to test if the cursor is
|
||
inside such a fragment, see the documentation of the function
|
||
@code{org-inside-LaTeX-fragment-p}.}. For example, @key{TAB} will
|
||
expand @code{fr} to @code{\frac@{@}@{@}} and position the cursor
|
||
correctly inside the first brace. Another @key{TAB} will get you into
|
||
the second brace. Even outside fragments, @key{TAB} will expand
|
||
environment abbreviations at the beginning of a line. For example, if
|
||
you write @samp{equ} at the beginning of a line and press @key{TAB},
|
||
this abbreviation will be expanded to an @code{equation} environment.
|
||
To get a list of all abbreviations, type @kbd{M-x cdlatex-command-help}.
|
||
@item
|
||
@kindex _
|
||
@kindex ^
|
||
@vindex cdlatex-simplify-sub-super-scripts
|
||
Pressing @kbd{_} and @kbd{^} inside a @LaTeX{} fragment will insert these
|
||
characters together with a pair of braces. If you use @key{TAB} to move
|
||
out of the braces, and if the braces surround only a single character or
|
||
macro, they are removed again (depending on the variable
|
||
@code{cdlatex-simplify-sub-super-scripts}).
|
||
@item
|
||
@kindex `
|
||
Pressing the backquote @kbd{`} followed by a character inserts math
|
||
macros, also outside @LaTeX{} fragments. If you wait more than 1.5 seconds
|
||
after the backquote, a help window will pop up.
|
||
@item
|
||
@kindex '
|
||
Pressing the single-quote @kbd{'} followed by another character modifies
|
||
the symbol before point with an accent or a font. If you wait more than
|
||
1.5 seconds after the single-quote, a help window will pop up. Character
|
||
modification will work only inside @LaTeX{} fragments; outside the quote
|
||
is normal.

@cindex exporting
|
||
|
||
Org mode documents can be exported into a variety of other formats. For
|
||
printing and sharing of notes, ASCII export produces a readable and simple
|
||
version of an Org file. HTML export allows you to publish a notes file on
|
||
the web, while the XOXO format provides a solid base for exchange with a
|
||
broad range of other applications. @LaTeX{} export lets you use Org mode and
|
||
its structured editing functions to easily create @LaTeX{} files. DocBook
|
||
export makes it possible to convert Org files to many other formats using
|
||
DocBook tools. OpenDocument Text (ODT) export allows seamless
|
||
collaboration across organizational boundaries. For project management you
|
||
can create gantt and resource charts by using TaskJuggler export. To
|
||
incorporate entries with associated times like deadlines or appointments into
|
||
a desktop calendar program like iCal, Org mode can also produce extracts in
|
||
the iCalendar format. Currently, Org mode only supports export, not import of
|
||
these different formats.
|
||
|
||
Org supports export of selected regions when @code{transient-mark-mode} is
|
||
enabled (default in Emacs 23).

You may use tags to select the parts of a document that should be exported,
|
||
or to exclude parts from export. This behavior is governed by two variables:
|
||
@code{org-export-select-tags} and @code{org-export-exclude-tags},
|
||
respectively defaulting to @code{'(:export:)} and @code{'(:noexport:)}.
|
||
|
||
@enumerate
|
||
@item
|
||
Org first checks if any of the @emph{select} tags is present in the
|
||
buffer. If yes, all trees that do not carry one of these tags will be
|
||
excluded. If a selected tree is a subtree, the heading hierarchy above it
|
||
will also be selected for export, but not the text below those headings.
|
||
|
||
@item
|
||
If none of the select tags is found, the whole buffer will be selected for
|
||
export.
|
||
|

Finally, all subtrees that are marked by any of the @emph{exclude} tags will
|

The variable @code{org-export-with-tasks} can be configured to select which

@example
|
||
@kbd{C-1 C-c C-e a}
|
||
@end example
|
||
|
||
@noindent
|
||
creates only top level headlines and does the rest as items. When
|
||
headlines are converted to items, the indentation of the text following
|
||
the headline is changed to fit nicely under the item. This is done with
|
||
the assumption that the first body line indicates the base indentation of
|
||
the body text. Any indentation larger than this is adjusted to preserve
|
||
the layout relative to the first line. Should there be lines with less
|
||
indentation than the first, these are left alone.

The HTML exporter lets you define a preamble and a postamble.
|
||
|
||
The default value for @code{org-export-html-preamble} is @code{t}, which
|

means that the preamble is inserted depending on the relevant formatting

||
string in @code{org-export-html-preamble-format}.
|
||
|
||
Setting @code{org-export-html-preamble} to a string will override the default
|

formatting string. Setting it to a function, will insert the output of the
|
||
function, which must be a string; such a function takes no argument but you
|
||
can check against the value of @code{opt-plist}, which contains the list of
|
||
publishing properties for the current file. Setting to @code{nil} will not
|
||
insert any preamble.
|
||
|
||
The default value for @code{org-export-html-postamble} is @code{'auto}, which
|
||
means that the HTML exporter will look for the value of
|
||
@code{org-export-author-info}, @code{org-export-email-info},
|
||
@code{org-export-creator-info} and @code{org-export-time-stamp-file},
|
||
@code{org-export-html-validation-link} and build the postamble from these
|
||
values. Setting @code{org-export-html-postamble} to @code{t} will insert the
|
||
postamble from the relevant formatting string found in
|
||
@code{org-export-html-postamble-format}. Setting it to @code{nil} will not

the same @i{relative} path as the published Org file. Links to other
|
||
@file{.org} files will be translated into HTML links under the assumption
|
||
that an HTML version also exists of the linked file, at the same relative

path. @samp{id:} links can then be used to jump to specific entries across

files. For information related to linking files while publishing them to a

|

If you want to specify attributes for links, you can do so using a special

@vindex org-export-html-inline-images
|

HTML export can inline images given as links in the Org file, and
|
||
it can make an image the clickable part of a link. By
|
||
default@footnote{But see the variable
|
||
@code{org-export-html-inline-images}.}, images are inlined if a link does
|
||
not have a description. So @samp{[[file:myimg.jpg]]} will be inlined,
|
||
while @samp{[[file:myimg.jpg][the image]]} will just produce a link
|
||
@samp{the image} that points to the image. If the description part
|
||
itself is a @code{file:} link or a @code{http:} URL pointing to an
|
||
image, this image will be inlined and activated so that clicking on the
|
||
image will activate the link. For example, to include a thumbnail that
|
||
will link to a high resolution version of the image, you could use:
|
||
|
||
@example
|
||
[[file:highres.jpg][file:thumb.jpg]]
|
||
@end example
|
||
|
||
If you need to add attributes to an inlined image, use a @code{#+ATTR_HTML}.
|
||
In the example below we specify the @code{alt} and @code{title} attributes to
|
||
support text viewers and accessibility, and align it to the right.
|
||
|
||
@cindex #+CAPTION
|

@LaTeX{} math snippets (@pxref{@LaTeX{} fragments}) can be displayed in two

different ways on HTML pages. The default is to use the

@uref{http://www.mathjax.org, MathJax system} which should work out of the

box with Org mode installation because @code{http://orgmode.org} serves
|

@file{MathJax} for Org mode users for small applications and for testing
|
||
purposes. @b{If you plan to use this regularly or on pages with significant
|
||
page views, you should install@footnote{Installation instructions can be
|
||
found on the MathJax website, see
|
||
@uref{http://www.mathjax.org/resources/docs/?installation.html}.} MathJax on
|
||
your own server in order to limit the load of our server.} To configure
|
||
@file{MathJax}, use the variable @code{org-export-html-mathjax-options} or
|
||
insert something like the following into the buffer:
|
||
|
||
@example
|
||
#+MATHJAX: align:"left" mathml:t path:"/MathJax/MathJax.js"
|

@code{org-export-html-mathjax-options} for the meaning of the parameters in

this line.
|
||
|
||
If you prefer, you can also request that @LaTeX{} fragments are processed
|
||
into small images that will be inserted into the browser page. Before the
|
||
availability of MathJax, this was the default method for Org files. This
|
||
method requires that the @file{dvipng} program is available on your system.

@cindex text areas, in HTML
|
||
An alternative way to publish literal code examples in HTML is to use text
|
||
areas, where the example can even be edited before pasting it into an
|
||
application. It is triggered by a @code{-t} switch at an @code{example} or
|
||
@code{src} block. Using this switch disables any options for syntax and
|
||
label highlighting, and line numbering, which may be present. You may also
|
||
use @code{-h} and @code{-w} switches to specify the height and width of the
|
||
text area, which default to the number of lines in the example, and 80,
|
||
respectively. For example
|
||
|
||
@example
|
||
#+BEGIN_EXAMPLE -t -w 40
|
||
(defun org-xor (a b)
|
||
"Exclusive or."

|
||
(for Org-wide settings) and @code{org-export-html-style-extra} (for more

For longer style definitions, you can use several such lines. You could also

referring to an external file.
|

In order to add styles to a subtree, use the @code{:HTML_CONTAINER_CLASS:}

@subsection JavaScript supported display of web pages
|
||
|
||
@cindex Rose, Sebastian
|
||
Sebastian Rose has written a JavaScript program especially designed to
|
||
enhance the web viewing experience of HTML files created with Org. This
|
||
program allows you to view large files in two different ways. The first one
|
||
is an @emph{Info}-like mode where each section is displayed separately and
|
||
navigation can be done with the @kbd{n} and @kbd{p} keys (and some other keys
|
||
as well, press @kbd{?} for an overview of the available keys). The second
|
||
view type is a @emph{folding} view much like Org provides inside Emacs. The
|
||
script is available at @url{http://orgmode.org/org-info.js} and you can find
|
||
the documentation for it at @url{http://orgmode.org/worg/code/org-info-js/}.
|
||
We host the script at our site, but if you use it a lot, you might
|
||
not want to be dependent on @url{orgmode.org} and prefer to install a local
|
||
copy on your own web server.
|
||
|
||
To use the script, you need to make sure that the @file{org-jsinfo.el} module
|
||
gets loaded. It should be loaded by default, but you can try @kbd{M-x
|
||
customize-variable @key{RET} org-modules @key{RET}} to convince yourself that
|
||
this is indeed the case. All it then takes to make use of the program is
|
||
adding a single line to the Org file:
|
||
|
||
@cindex #+INFOJS_OPT
|
||
@example
|
||
#+INFOJS_OPT: view:info toc:nil
|
||
@end example
|
||
|
||
@noindent
|
||
If this line is found, the HTML header will automatically contain the code
|
||
needed to invoke the script. Using the line above, you can set the following
|
||
viewing options:
|
||
|
||
@example
|
||
path: @r{The path to the script. The default is to grab the script from}
|
||
@r{@url{http://orgmode.org/org-info.js}, but you might want to have}
|
||
@r{a local copy and use a path like @samp{../scripts/org-info.js}.}
|
||
view: @r{Initial view when website is first shown. Possible values are:}
|
||
info @r{Info-like interface with one section per page.}
|
||
overview @r{Folding interface, initially showing only top-level.}
|
||
content @r{Folding interface, starting with all headlines visible.}
|
||
showall @r{Folding interface, all headlines and text visible.}
|
||
sdepth: @r{Maximum headline level that will still become an independent}
|
||
@r{section for info and folding modes. The default is taken from}
|
||
@r{@code{org-export-headline-levels} (= the @code{H} switch in @code{#+OPTIONS}).}
|
||
@r{If this is smaller than in @code{org-export-headline-levels}, each}
|
||
@r{info/folding section can still contain child headlines.}
|
||
toc: @r{Should the table of contents @emph{initially} be visible?}
|
||
@r{Even when @code{nil}, you can always get to the "toc" with @kbd{i}.}
|
||
tdepth: @r{The depth of the table of contents. The defaults are taken from}
|
||
@r{the variables @code{org-export-headline-levels} and @code{org-export-with-toc}.}
|
||
ftoc: @r{Does the CSS of the page specify a fixed position for the "toc"?}
|
||
@r{If yes, the toc will never be displayed as a section.}
|
||
ltoc: @r{Should there be short contents (children) in each section?}
|
||
@r{Make this @code{above} if the section should be above initial text.}
|
||
mouse: @r{Headings are highlighted when the mouse is over them. Should be}
|
||
@r{@samp{underline} (default) or a background color like @samp{#cccccc}.}
|
||
buttons: @r{Should view-toggle buttons be everywhere? When @code{nil} (the}

If you want that transition to occur at a different level, specify it

with a numeric prefix argument. For example,

Images that are linked to without a description part in the link, like
|
||
@samp{[[file:img.jpg]]} or @samp{[[./img.jpg]]} will be inserted into the PDF
|
||
output file resulting from @LaTeX{} processing. Org will use an
|
||
@code{\includegraphics} macro to insert the image. If you have specified a
|
||
caption and/or a label as described in @ref{Images and tables}, the figure
|
||
will be wrapped into a @code{figure} environment and thus become a floating
|
||
element. You can use an @code{#+ATTR_LaTeX:} line to specify various other
|
||
options. You can ask org to export an image as a float without specifying
|
||
a label or a caption by using the keyword @code{float} in this line. Various
|
||
optional arguments to the @code{\includegraphics} macro can also be specified
|
||
in this fashion. To modify the placement option of the floating environment,
|
||
add something like @samp{placement=[h!]} to the attributes. It is to be noted
|
||
this option can be used with tables as well@footnote{One can also take
|
||
advantage of this option to pass other, unrelated options into the figure or
|
||
table environment. For an example see the section ``Exporting org files'' in
|
||
@url{http://orgmode.org/worg/org-hacks.html}}. For example the
|
||
@code{#+ATTR_LaTeX:} line below is exported as the @code{figure} environment
|
||
below it.
|
||
|
||
If you would like to let text flow around the image, add the word @samp{wrap}
|
||
to the @code{#+ATTR_LaTeX:} line, which will make the figure occupy the left
|
||
half of the page. To fine-tune, the @code{placement} field will be the set
|
||
of additional arguments needed by the @code{wrapfigure} environment. Note
|
||
that if you change the size of the image, you need to use compatible settings
|
||
for @code{\includegraphics} and @code{wrapfigure}.
|
||
|
||
@cindex #+CAPTION
|
||
@cindex #+LABEL
|

@end example
|
||
|
||
If you wish to include an image which spans multiple columns in a page, you
|
||
can use the keyword @code{multicolumn} in the @code{#+ATTR_LaTeX} line. This
|
||
will export the image wrapped in a @code{figure*} environment.
|
||
|
||
If you need references to a label created in this way, write

||
@samp{\ref@{fig:SED-HR4049@}} just like in @LaTeX{}.

@subsection Beamer class export
|
||
|
||
The @LaTeX{} class @file{beamer} allows production of high quality presentations
|
||
using @LaTeX{} and pdf processing. Org mode has special support for turning an
|
||
Org mode file or tree into a @file{beamer} presentation.
|
||
|
||
When the @LaTeX{} class for the current buffer (as set with @code{#+LaTeX_CLASS:
|
||
beamer}) or subtree (set with a @code{LaTeX_CLASS} property) is
|
||
@code{beamer}, a special export mode will turn the file or tree into a beamer
|
||
presentation. Any tree with not-too-deep level nesting should in principle be
|
||
exportable as a beamer presentation. By default, the top-level entries (or
|
||
the first level below the selected subtree heading) will be turned into
|
||
frames, and the outline structure below this level will become itemize lists.
|
||
You can also configure the variable @code{org-beamer-frame-level} to a
|
||
different level---then the hierarchy above frames will produce the sectioning
|
||
structure of the presentation.
|
||
|
||
A template for useful in-buffer settings or properties can be inserted into
|
||
the buffer with @kbd{M-x org-insert-beamer-options-template}. Among other
|
||
things, this will install a column view format which is very handy for
|
||
editing special properties used by beamer.
|
||
|
||
You can influence the structure of the presentation using the following
|
||
properties:
|
||
|
||
@table @code
|
||
@item BEAMER_env
|
||
The environment that should be used to format this entry. Valid environments
|
||
are defined in the constant @code{org-beamer-environments-default}, and you
|
||
can define more in @code{org-beamer-environments-extra}. If this property is
|
||
set, the entry will also get a @code{:B_environment:} tag to make this
|
||
visible. This tag has no semantic meaning, it is only a visual aid.
|
||
@item BEAMER_envargs
|
||
The beamer-special arguments that should be used for the environment, like
|
||
@code{[t]} or @code{[<+->]} of @code{<2-3>}. If the @code{BEAMER_col}
|
||
property is also set, something like @code{C[t]} can be added here as well to
|
||
set an options argument for the implied @code{columns} environment.
|
||
@code{c[t]} or @code{c<2->} will set an options for the implied @code{column}
|
||
environment.
|
||
@item BEAMER_col
|
||
The width of a column that should start with this entry. If this property is
|
||
set, the entry will also get a @code{:BMCOL:} property to make this visible.
|
||
Also this tag is only a visual aid. When this is a plain number, it will be
|
||
interpreted as a fraction of @code{\textwidth}. Otherwise it will be assumed
|
||
that you have specified the units, like @samp{3cm}. The first such property
|
||
in a frame will start a @code{columns} environment to surround the columns.
|
||
This environment is closed when an entry has a @code{BEAMER_col} property
|
||
with value 0 or 1, or automatically at the end of the frame.
|
||
@item BEAMER_extra
|
||
Additional commands that should be inserted after the environment has been
|
||
opened. For example, when creating a frame, this can be used to specify
|
||
transitions.
|
||
@end table
|
||
|
||
Frames will automatically receive a @code{fragile} option if they contain
|
||
source code that uses the verbatim environment. Special @file{beamer}
|
||
specific code can be inserted using @code{#+BEAMER:} and
|
||
@code{#+BEGIN_beamer...#+end_beamer} constructs, similar to other export
|
||
backends, but with the difference that @code{#+LaTeX:} stuff will be included
|
||
in the presentation as well.
|
||
|
||
Outline nodes with @code{BEAMER_env} property value @samp{note} or
|
||
@samp{noteNH} will be formatted as beamer notes, i,e, they will be wrapped
|
||
into @code{\note@{...@}}. The former will include the heading as part of the
|
||
note text, the latter will ignore the heading of that node. To simplify note
|
||
generation, it is actually enough to mark the note with a @emph{tag} (either
|
||
@code{:B_note:} or @code{:B_noteNH:}) instead of creating the
|
||
@code{BEAMER_env} property.
|
||
|
||
You can turn on a special minor mode @code{org-beamer-mode} for editing
|
||
support with
|
||
|
||
@example
|
||
#+STARTUP: beamer
|
||
@end example
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-b,org-beamer-select-environment}
|
||
In @code{org-beamer-mode}, this key offers fast selection of a beamer
|
||
environment or the @code{BEAMER_col} property.
|
||
@end table
|
||
|
||
Column view provides a great way to set the environment of a node and other
|
||
important parameters. Make sure you are using a COLUMN format that is geared
|
||
toward this special purpose. The command @kbd{M-x
|
||
org-insert-beamer-options-template} defines such a format.
|
||
|
||
Here is a simple example Org document that is intended for beamer export.

Org contains a DocBook exporter written by Baoqiu Cui. Once an Org file is
|
||
exported to DocBook format, it can be further processed to produce other
|
||
formats, including PDF, HTML, man pages, etc., using many available DocBook
|
||
tools and stylesheets.
|
||
|
||
Currently DocBook exporter only supports DocBook V5.0.

@cindex property EXPORT_FILE_NAME
|
||
Export as DocBook file. For an Org file, @file{myfile.org}, the DocBook XML
|
||
file will be @file{myfile.xml}. The file will be overwritten without
|
||
warning. If there is an active region@footnote{This requires
|

@code{transient-mark-mode} to be turned on}, only the region will be
|
||
exported. If the selected region is a single tree@footnote{To select the
|

||
DocBook file with the following constructs:
|
||
|
||
@cindex #+DOCBOOK
|
||
@cindex #+BEGIN_DOCBOOK
|
||
@example
|
||
#+DOCBOOK: Literal DocBook code for export

||
@noindent or
|
||
@cindex #+BEGIN_DOCBOOK
|
||
|
||
@example
|
||
#+BEGIN_DOCBOOK
|
||
All lines between these markers are exported by DocBook exporter
|
||
literally.
|
||
#+END_DOCBOOK
|
||
@end example
|
||
|
||
For example, you can use the following lines to include a DocBook warning
|
||
admonition. As to what this warning says, you should pay attention to the
|
||
document context when quoting DocBook code in Org files. You may make
|
||
exported DocBook XML files invalid by not quoting DocBook code correctly.
|
||
|
||
@example
|
||
#+BEGIN_DOCBOOK
|
||
<warning>
|
||
<para>You should know what you are doing when quoting DocBook XML code

|
||
|
||
DocBook exporter exports Org files as articles using the @code{article}
|
||
element in DocBook. Recursive sections, i.e.@: @code{section} elements, are
|
||
used in exported articles. Top level headlines in Org files are exported as
|
||
top level sections, and lower level headlines are exported as nested
|
||
sections. The entire structure of Org files will be exported completely, no
|
||
matter how many nested levels of headlines there are.
|
||
|
||
Using recursive sections makes it easy to port and reuse exported DocBook
|
||
code in other DocBook document types like @code{book} or @code{set}.

|
||
|
||
Tables in Org files are exported as HTML tables, which have been supported since
|
||
DocBook V4.3.
|
||
|
||
If a table does not have a caption, an informal table is generated using the
|
||
@code{informaltable} element; otherwise, a formal table will be generated
|
||
using the @code{table} element.

|
||
|
||
Images that are linked to without a description part in the link, like
|
||
@samp{[[file:img.jpg]]} or @samp{[[./img.jpg]]}, will be exported to DocBook
|
||
using @code{mediaobject} elements. Each @code{mediaobject} element contains
|
||
an @code{imageobject} that wraps an @code{imagedata} element. If you have
|
||
specified a caption for an image as described in @ref{Images and tables}, a
|
||
@code{caption} element will be added in @code{mediaobject}. If a label is
|
||
also specified, it will be exported as an @code{xml:id} attribute of the
|
||
@code{mediaobject} element.
|
||
|
||
@vindex org-export-docbook-default-image-attributes
|
||
Image attributes supported by the @code{imagedata} element, like @code{align}
|
||
or @code{width}, can be specified in two ways: you can either customize
|
||
variable @code{org-export-docbook-default-image-attributes} or use the
|
||
@code{#+ATTR_DOCBOOK:} line. Attributes specified in variable
|
||
@code{org-export-docbook-default-image-attributes} are applied to all inline
|
||
images in the Org file to be exported (unless they are overridden by image
|
||
attributes specified in @code{#+ATTR_DOCBOOK:} lines).
|
||
|
||
The @code{#+ATTR_DOCBOOK:} line can be used to specify additional image
|
||
attributes or override default image attributes for individual images. If
|
||
the same attribute appears in both the @code{#+ATTR_DOCBOOK:} line and
|
||
variable @code{org-export-docbook-default-image-attributes}, the former
|
||
takes precedence. Here is an example about how image attributes can be
|
||
set:
|
||
|
||
@cindex #+CAPTION
|
||
@cindex #+LABEL
|

corresponding entities, these special characters are recognized.
|
||
|

@subsection Extending ODT export
|
||
|
||
The ODT exporter can interface with a variety of document
|
||
converters and supports popular converters out of the box. As a result, you
|
||
can use it to export to formats like @samp{doc} or convert a document from
|
||
one format (say @samp{csv}) to another format (say @samp{ods} or @samp{xls}).
|
||
|
||
@cindex @file{unoconv}
|
||
@cindex LibreOffice
|
||
If you have a working installation of LibreOffice, a document converter is
|
||
pre-configured for you and you can use it right away. If you would like to
|
||
use @file{unoconv} as your preferred converter, customize the variable
|
||
@code{org-export-odt-convert-process} to point to @code{unoconv}. You can
|
||
also use your own favorite converter or tweak the default settings of the
|
||
@file{LibreOffice} and @samp{unoconv} converters. @xref{Configuring a
|
||
document converter}.
|
||
|
||
@subsubsection Automatically exporting to other formats
|
||
@anchor{x-export-to-other-formats}
|
||
|
||
@vindex org-export-odt-preferred-output-format
|
||
Very often, you will find yourself exporting to ODT format, only to
|
||
immediately save the exported document to other formats like @samp{doc},
|
||
@samp{docx}, @samp{rtf}, @samp{pdf} etc. In such cases, you can specify your
|
||
preferred output format by customizing the variable
|
||
@code{org-export-odt-preferred-output-format}. This way, the export commands
|
||
(@pxref{x-export-to-odt,,Exporting to ODT}) can be extended to export to a
|
||
format that is of immediate interest to you.
|
||
|
||
@subsubsection Converting between document formats
|
||
@anchor{x-convert-to-other-formats}
|
||
|
||
There are many document converters in the wild which support conversion to
|
||
and from various file formats, including, but not limited to the
|
||
ODT format. LibreOffice converter, mentioned above, is one such
|
||
converter. Once a converter is configured, you can interact with it using
|
||
the following command.
|
||
|
||
@vindex org-export-odt-convert
|
||
@table @kbd
|
||
|
||
@item M-x org-export-odt-convert
|
||

|
||
argument, also open the newly produced file.

@subsection Applying custom styles
|

@cindex styles, custom
|
||
@cindex template, custom
|
||
|
||
The ODT exporter ships with a set of OpenDocument styles
|
||
(@pxref{Working with OpenDocument style files}) that ensure a well-formatted
|
||
output. These factory styles, however, may not cater to your specific
|
||
tastes. To customize the output, you can either modify the above styles
|
||
files directly, or generate the required styles using an application like
|
||
LibreOffice. The latter method is suitable for expert and non-expert
|
||
users alike, and is described here.
|
||
|
||
@subsubsection Applying custom styles - the easy way
|
||
|
||
@enumerate
|
||
@item
|
||
Create a sample @file{example.org} file with the below settings and export it
|
||
to ODT format.
|
||
|
||
@example
|
||
#+OPTIONS: H:10 num:t
|
||
@end example
|
||
|
||
@item
|
||
Open the above @file{example.odt} using LibreOffice. Use the @file{Stylist}
|
||
to locate the target styles - these typically have the @samp{Org} prefix -
|
||
and modify those to your taste. Save the modified file either as an
|
||
OpenDocument Text (@file{.odt}) or OpenDocument Template (@file{.ott}) file.
|
||
|
||
@item
|
||
@cindex #+ODT_STYLES_FILE
|
||
@vindex org-export-odt-styles-file
|
||
Customize the variable @code{org-export-odt-styles-file} and point it to the
|
||
newly created file. For additional configuration options
|
||
@pxref{x-overriding-factory-styles,,Overriding factory styles}.
|
||
|
||
If you would like to choose a style on a per-file basis, you can use the
|
||
@code{#+ODT_STYLES_FILE} option. A typical setting will look like
|
||
|
||
@example
|
||
#+ODT_STYLES_FILE: "/path/to/example.ott"
|
||
@end example
|
||
|
||
or
|
||
|
||
@example
|
||
#+ODT_STYLES_FILE: ("/path/to/file.ott" ("styles.xml" "image/hdr.png"))
|
||
@end example
|
||
|
||
@end enumerate
|
||
|
||
@subsubsection Using third-party styles and templates
|
||
|
||
You can use third-party styles and templates for customizing your output.
|
||
This will produce the desired output only if the template provides all
|
||
style names that the @samp{ODT} exporter relies on. Unless this condition is
|
||
met, the output is going to be less than satisfactory. So it is highly
|
||
recommended that you only work with templates that are directly derived from
|
||
the factory settings.

|
||
@cindex tables, in DocBook export
|
||
|
||
Export of native Org mode tables (@pxref{Tables}) and simple @file{table.el}
|
||
tables is supported. However, export of complex @file{table.el} tables -
|
||
tables that have column or row spans - is not supported. Such tables are
|
||
stripped from the exported document.
|
||
|
||
By default, a table is exported with top and bottom frames and with rules
|
||
separating row and column groups (@pxref{Column groups}). Furthermore, all
|
||
tables are typeset to occupy the same width. If the table specifies
|
||
alignment and relative width for its columns (@pxref{Column width and
|
||
alignment}) then these are honored on export.@footnote{The column widths are
|
||
interpreted as weighted ratios with the default weight being 1}
|
||
|
||
@cindex #+ATTR_ODT
|
||
You can control the width of the table by specifying @code{:rel-width}
|
||
property using an @code{#+ATTR_ODT} line.
|
||
|
||
For example, consider the following table which makes use of all the rules
|
||
mentioned above.
|
||
|
||
@example
|
||
#+ATTR_ODT: :rel-width 50
|
||
| Area/Month | Jan | Feb | Mar | Sum |
|

|
||
|---------------+-------+-------+-------+-------|
|
||
| Sum | 16 | 123 | 2560 | 2699 |
|
||
@end example
|
||
|
||
On export, the table will occupy 50% of text area. The columns will be sized
|
||
(roughly) in the ratio of 13:5:5:5:6. The first column will be left-aligned
|
||
and rest of the columns will be right-aligned. There will be vertical rules
|
||
after separating the header and last columns from other columns. There will
|
||
be horizontal rules separating the header and last rows from other rows.
|
||
|
||
If you are not satisfied with the above formatting options, you can create
|
||
custom table styles and associate them with a table using the
|
||

@cindex identify, ImageMagick
|
||
@vindex org-export-odt-pixels-per-inch
|
||
The exporter specifies the desired size of the image in the final document in
|
||
units of centimeters. In order to scale the embedded images, the exporter
|
||
queries for pixel dimensions of the images using one of a) ImageMagick's
|
||
@file{identify} program or b) Emacs `create-image' and `image-size'
|
||
APIs.@footnote{Use of @file{ImageMagick} is only desirable. However, if you
|
||
routinely produce documents that have large images or you export your Org
|
||
files that has images using a Emacs batch script, then the use of
|
||
@file{ImageMagick} is mandatory.} The pixel dimensions are subsequently
|
||
converted in to units of centimeters using
|
||
@code{org-export-odt-pixels-per-inch}. The default value of this variable is
|
||
set to @code{display-pixels-per-inch}. You can tweak this variable to

@subsection Labels and captions in ODT export
|
||
|
||
You can label and caption various category of objects - an inline image, a
|
||
table, a @LaTeX{} fragment or a Math formula - using @code{#+LABEL} and
|
||
@code{#+CAPTION} lines. @xref{Images and tables}. ODT exporter enumerates
|
||
each labeled or captioned object of a given category separately. As a
|
||
result, each such object is assigned a sequence number based on order of it's
|
||
appearance in the Org file.
|
||
|
||
In the exported document, a user-provided caption is augmented with the
|
||
category and sequence number. Consider the following inline image in an Org
|
||
file.
|
||
|
||
@example
|
||
#+CAPTION: Bell curve
|
||
#+LABEL: fig:SED-HR4049
|
||
[[./img/a.png]]
|
||
@end example
|
||
|
||
It could be rendered as shown below in the exported document.
|
||
|
||
@example
|
||
Figure 2: Bell curve
|
||
@end example
|
||
|
||
@vindex org-export-odt-category-strings
|
||
You can modify the category component of the caption by customizing the
|
||
variable @code{org-export-odt-category-strings}. For example, to tag all
|
||
embedded images with the string @samp{Illustration} (instead of the default
|
||
@samp{Figure}) use the following setting.
|
||
|
||
@lisp
|
||
(setq org-export-odt-category-strings
|
||
'(("en" "Table" "Illustration" "Equation" "Equation")))
|
||
@end lisp
|

The ODT exporter relies on two files for generating its output.
|
||
These files are bundled with the distribution under the directory pointed to
|
||
by the variable @code{org-odt-styles-dir}. The two files are:
|
||
|
||
@itemize
|
||
@anchor{x-orgodtstyles-xml}
|
||
@item
|
||
@file{OrgOdtStyles.xml}
|
||
|
||
This file contributes to the @file{styles.xml} file of the final @samp{ODT}
|
||
document. This file gets modified for the following purposes:
|
||
@enumerate
|
||
|
||
@item
|
||
To control outline numbering based on user settings.
|
||
|
||
@item
|

@file{OrgOdtContentTemplate.xml}
|

This file contributes to the @file{content.xml} file of the final @samp{ODT}
|
||
document. The contents of the Org outline are inserted between the
|
||
@samp{<office:text>}@dots{}@samp{</office:text>} elements of this file.
|
||
|
||
Apart from serving as a template file for the final @file{content.xml}, the
|
||
file serves the following purposes:
|
||
@enumerate
|
||
|
||
@item
|
||
It contains automatic styles for formatting of tables which are referenced by
|

the exporter.
|
||
|
||
@item
|

final output. You can specify one of the following values:
|
||
|
||
@enumerate
|
||
@item A @file{styles.xml} file
|

@subsubsection Creating one-off styles
|
||
|
||
There are times when you would want one-off formatting in the exported
|
||
document. You can achieve this by embedding raw OpenDocument XML in the Org
|
||
file. The use of this feature is better illustrated with couple of examples.
|
||
|
||
@enumerate
|
||
@item Embedding ODT tags as part of regular text
|
||
|
||
You can include simple OpenDocument tags by prefixing them with
|
||
@samp{@@}. For example, to highlight a region of text do the following:
|
||
|
||
@example
|
||
@@<text:span text:style-name="Highlight">This is a
|
||
highlighted text@@</text:span>. But this is a
|
||
regular text.
|
||
@end example
|
||
|
||
@strong{Hint:} To see the above example in action, edit your
|
||
@file{styles.xml} (@pxref{x-orgodtstyles-xml,,Factory styles}) and add a
|
||
custom @samp{Highlight} style as shown below.
|
||
|
||
@example
|
||
<style:style style:name="Highlight" style:family="text">
|
||
<style:text-properties fo:background-color="#ff0000"/>
|
||
</style:style>
|
||
@end example
|
||
|
||
@item Embedding a one-line OpenDocument XML
|
||
|
||
You can add a simple OpenDocument one-liner using the @code{#+ODT:}
|
||
directive. For example, to force a page break do the following:
|
||
|
||
@example
|
||
#+ODT: <text:p text:style-name="PageBreak"/>
|
||
@end example
|
||
|
||
@strong{Hint:} To see the above example in action, edit your
|
||
@file{styles.xml} (@pxref{x-orgodtstyles-xml,,Factory styles}) and add a
|
||
custom @samp{PageBreak} style as shown below.
|
||
|
||
@example
|
||
<style:style style:name="PageBreak" style:family="paragraph"
|
||
style:parent-style-name="Text_20_body">
|
||
<style:paragraph-properties fo:break-before="page"/>
|
||
</style:style>
|
||
@end example
|
||
|
||
@item Embedding a block of OpenDocument XML
|
||
|
||
You can add a large block of OpenDocument XML using the
|
||
@code{#+BEGIN_ODT}@dots{}@code{#+END_ODT} construct.
|
||
|
||
For example, to create a one-off paragraph that uses bold text, do the
|
||
following:
|
||
|
||
@example
|
||
#+BEGIN_ODT
|
||
<text:p text:style-name="Text_20_body_20_bold">
|
||
This paragraph is specially formatted and uses bold text.
|
||
</text:p>

@end example
|

|
||
In the above example, you used a template named @samp{Custom} and installed
|
||
two table styles with the names @samp{TableWithHeaderRowAndColumn} and
|
||
@samp{TableWithFirstRowandLastRow}. (@strong{Important:} The OpenDocument
|
||
styles needed for producing the above template have been pre-defined for you.
|
||
These styles are available under the section marked @samp{Custom Table
|
||
Template} in @file{OrgOdtContentTemplate.xml}
|
||
(@pxref{x-orgodtcontenttemplate-xml,,Factory styles}). If you need
|
||
additional templates you have to define these styles yourselves.
|
||
|
||
@subsubheading Custom table styles - the nitty-gritty
|
||
To use this feature proceed as follows:
|
||
|
||
@enumerate
|
||
@item
|
||
Create a table template@footnote{See the @code{<table:table-template>}
|
||
element of the OpenDocument-v1.2 specification}
|
||
|
||
A table template is nothing but a set of @samp{table-cell} and
|
||
@samp{paragraph} styles for each of the following table cell categories:
|
||
|
||
@itemize @minus
|
||
@item Body
|
||
@item First column
|
||
@item Last column
|
||
@item First row
|
||
@item Last row
|
||
@item Even row
|
||
@item Odd row
|
||
@item Even column
|
||
@item Odd Column
|
||
@end itemize
|
||
|
||
The names for the above styles must be chosen based on the name of the table
|
||
template using a well-defined convention.
|
||
|
||
The naming convention is better illustrated with an example. For a table
|
||
template with the name @samp{Custom}, the needed style names are listed in
|
||
the following table.
|
||
|
||
@multitable {Table cell type} {CustomEvenColumnTableCell} {CustomEvenColumnTableParagraph}
|
||
@headitem Table cell type
|

|
||
@tab @samp{CustomFirstColumnTableParagraph}
|
||
@item Last column
|
||
@tab @samp{CustomLastColumnTableCell}
|
||
@tab @samp{CustomLastColumnTableParagraph}
|
||
@item First row
|
||
@tab @samp{CustomFirstRowTableCell}
|
||
@tab @samp{CustomFirstRowTableParagraph}
|
||
@item Last row
|
||
@tab @samp{CustomLastRowTableCell}
|
||
@tab @samp{CustomLastRowTableParagraph}
|
||
@item Even row
|
||
@tab @samp{CustomEvenRowTableCell}
|
||
@tab @samp{CustomEvenRowTableParagraph}
|
||
@item Odd row
|
||
@tab @samp{CustomOddRowTableCell}
|
||
@tab @samp{CustomOddRowTableParagraph}
|
||
@item Even column
|
||
@tab @samp{CustomEvenColumnTableCell}
|
||
@tab @samp{CustomEvenColumnTableParagraph}
|
||
@item Odd column
|
||
@tab @samp{CustomOddColumnTableCell}
|
||
@tab @samp{CustomOddColumnTableParagraph}
|
||
@end multitable
|
||
|
||
To create a table template with the name @samp{Custom}, define the above
|
||
styles in the
|
||
@code{<office:automatic-styles>}...@code{</office:automatic-styles>} element
|
||
of the content template file (@pxref{x-orgodtcontenttemplate-xml,,Factory
|
||
styles}).
|
||
|
||
@item
|
||
Define a table style@footnote{See the attributes @code{table:template-name},
|
||
@code{table:use-first-row-styles}, @code{table:use-last-row-styles},
|
||
@code{table:use-first-column-styles}, @code{table:use-last-column-styles},
|
||
@code{table:use-banding-rows-styles}, and
|
||
@code{table:use-banding-column-styles} of the @code{<table:table>} element in
|
||
the OpenDocument-v1.2 specification}
|
||
|
||
@vindex org-export-odt-table-styles
|
||
To define a table style, create an entry for the style in the variable
|
||
@code{org-export-odt-table-styles} and specify the following:
|
||
|
||
@itemize @minus
|
||
@item the name of the table template created in step (1)
|
||
@item the set of cell styles in that template that are to be activated
|
||
@end itemize
|
||
|
||
For example, the entry below defines two different table styles
|
||
@samp{TableWithHeaderRowAndColumn} and @samp{TableWithFirstRowandLastRow}
|
||
based on the same template @samp{Custom}. The styles achieve their intended
|
||
effect by selectively activating the individual cell styles in that template.

@subsubsection Validating OpenDocument XML
|
||
|
||
Occasionally, you will discover that the document created by the
|
||
ODT exporter cannot be opened by your favorite application. One of
|
||
the common reasons for this is that the @file{.odt} file is corrupt. In such
|
||
cases, you may want to validate the document against the OpenDocument RELAX
|
||
NG Compact Syntax (RNC) schema.
|
||
|
||
For de-compressing the @file{.odt} file@footnote{@file{.odt} files are
|
||
nothing but @samp{zip} archives}: @inforef{File Archives,,emacs}. For

schema-locating rules in a single folder, you can customize the variable

@uref{http://www.taskjuggler.org/, TaskJuggler} is a project management tool.

It provides an optimizing scheduler that computes your project time lines and
|
||
resource assignments based on the project outline and the constraints that
|
||
you have provided.
|
||
|
||
The TaskJuggler exporter is a bit different from other exporters, such as the
|
||
@code{HTML} and @LaTeX{} exporters for example, in that it does not export all the
|
||
nodes of a document or strictly follow the order of the nodes in the
|
||
document.
|
||
|
||
Instead the TaskJuggler exporter looks for a tree that defines the tasks and
|
||
a optionally tree that defines the resources for this project. It then
|
||
creates a TaskJuggler file based on these trees and the attributes defined in
|
||
all the nodes.

@subsection Tasks
|
||
|
||
@vindex org-export-taskjuggler-project-tag
|
||
Create your tasks as you usually do with Org mode. Assign efforts to each
|
||
task using properties (it is easiest to do this in the column view). You
|
||
should end up with something similar to the example by Peter Jones in
|
||
@url{http://www.contextualdevelopment.com/static/artifacts/articles/2008/project-planning/project-planning.org}.
|
||
Now mark the top node of your tasks with a tag named
|
||
@code{:taskjuggler_project:} (or whatever you customized
|
||
@code{org-export-taskjuggler-project-tag} to). You are now ready to export
|
||
the project plan with @kbd{C-c C-e J} which will export the project plan and
|
||
open a gantt chart in TaskJugglerUI.
|
||
|
||
@subsection Resources
|
||
|
||
@vindex org-export-taskjuggler-resource-tag
|
||
Next you can define resources and assign those to work on specific tasks. You
|
||
can group your resources hierarchically. Tag the top node of the resources
|
||
with @code{:taskjuggler_resource:} (or whatever you customized
|
||
@code{org-export-taskjuggler-resource-tag} to). You can optionally assign an
|
||
identifier (named @samp{resource_id}) to the resources (using the standard
|
||
Org properties commands, @pxref{Property syntax}) or you can let the exporter
|
||
generate identifiers automatically (the exporter picks the first word of the
|
||
headline as the identifier as long as it is unique---see the documentation of
|
||
@code{org-taskjuggler-get-unique-id}). Using that identifier you can then
|
||
allocate resources to tasks. This is again done with the @samp{allocate}
|
||
property on the tasks. Do this in column view or when on the task type
|
||
@kbd{C-c C-x p allocate @key{RET} <resource_id> @key{RET}}.
|
||
|
||
Once the allocations are done you can again export to TaskJuggler and check
|
||
in the Resource Allocation Graph which person is working on what task at what
|
||
time.
|
||
|
||
@subsection Export of properties
|
||
|
||
The exporter also takes TODO state information into consideration, i.e.@: if a
|
||
task is marked as done it will have the corresponding attribute in
|
||
TaskJuggler (@samp{complete 100}). Also it will export any property on a task
|
||
resource or resource node which is known to TaskJuggler, such as
|
||
@samp{limits}, @samp{vacation}, @samp{shift}, @samp{booking},
|
||
@samp{efficiency}, @samp{journalentry}, @samp{rate} for resources or
|
||
@samp{account}, @samp{start}, @samp{note}, @samp{duration}, @samp{end},
|
||
@samp{journalentry}, @samp{milestone}, @samp{reference}, @samp{responsible},
|
||
@samp{scheduling}, etc for tasks.
|
||
|
||
@subsection Dependencies
|
||
|
||
The exporter will handle dependencies that are defined in the tasks either
|
||
with the @samp{ORDERED} attribute (@pxref{TODO dependencies}), with the
|
||
@samp{BLOCKER} attribute (see @file{org-depend.el}) or alternatively with a
|
||
@samp{depends} attribute. Both the @samp{BLOCKER} and the @samp{depends}
|
||
attribute can be either @samp{previous-sibling} or a reference to an
|
||
identifier (named @samp{task_id}) which is defined for another task in the
|
||
project. @samp{BLOCKER} and the @samp{depends} attribute can define multiple
|
||
dependencies separated by either space or comma. You can also specify
|
||
optional attributes on the dependency by simply appending it. The following
|
||
examples should illustrate this:
|
||
|
||
@example
|
||
* Preparation
|
||
:PROPERTIES:
|
||
:task_id: preparation
|
||
:ORDERED: t
|
||

:END:
|
||
@end example
|
||
|
||
@subsection Reports
|
||
|
||
@vindex org-export-taskjuggler-default-reports
|
||
TaskJuggler can produce many kinds of reports (e.g.@: gantt chart, resource
|
||
allocation, etc). The user defines what kind of reports should be generated
|
||
for a project in the TaskJuggler file. The exporter will automatically insert
|
||
some default reports in the file. These defaults are defined in
|
||
@code{org-export-taskjuggler-default-reports}. They can be modified using
|
||
customize along with a number of other options. For a more complete list, see
|
||
@kbd{M-x customize-group @key{RET} org-export-taskjuggler @key{RET}}.

@vindex org-icalendar-categories
|

|
||
Some people use Org mode for keeping track of projects, but still prefer a
|
||
standard calendar application for anniversaries and appointments. In this
|
||
case it can be useful to show deadlines and other time-stamped items in Org
|
||
files in the calendar application. Org mode can export calendar information
|
||
in the standard iCalendar format. If you also want to have TODO entries
|
||
included in the export, configure the variable
|
||
@code{org-icalendar-include-todo}. Plain timestamps are exported as VEVENT,
|
||
and TODO items as VTODO. It will also create events from deadlines that are
|
||
in non-TODO items. Deadlines and scheduling dates in TODO items will be used
|
||
to set the start and due dates for the TODO entry@footnote{See the variables
|
||
@code{org-icalendar-use-deadline} and @code{org-icalendar-use-scheduled}.}.
|
||
As categories, it will use the tags locally defined in the heading, and the
|
||
file/tree category@footnote{To add inherited tags or the TODO state,
|
||
configure the variable @code{org-icalendar-categories}.}. See the variable
|
||
@code{org-icalendar-alarm-time} for a way to assign alarms to entries with a
|
||
time.
|
||
|
||
@vindex org-icalendar-store-UID
|
||
@cindex property, ID
|
||
The iCalendar standard requires each entry to have a globally unique
|
||
identifier (UID). Org creates these identifiers during export. If you set
|
||
the variable @code{org-icalendar-store-UID}, the UID will be stored in the
|
||
@code{:ID:} property of the entry and re-used next time you report this
|
||
entry. Since a single entry can give rise to multiple iCalendar entries (as
|
||
a timestamp, a deadline, a scheduled item, and as a TODO item), Org adds
|
||
prefixes to the UID, depending on what triggered the inclusion of the entry.
|
||
In this way the UID remains unique, but a synchronization program can still
|
||
figure out from which entry all the different instances originate.
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-e i,org-export-icalendar-this-file}
|
||
Create iCalendar entries for the current file and store them in the same
|
||
directory, using a file extension @file{.ics}.
|
||
@orgcmd{C-c C-e I, org-export-icalendar-all-agenda-files}
|
||
@vindex org-agenda-files
|
||
Like @kbd{C-c C-e i}, but do this for all files in
|
||
@code{org-agenda-files}. For each of these files, a separate iCalendar
|
||
file will be written.
|
||
@orgcmd{C-c C-e c,org-export-icalendar-combine-agenda-files}
|
||
@vindex org-combined-agenda-icalendar-file
|
||
Create a single large iCalendar file from all files in
|
||
@code{org-agenda-files} and write it to the file given by
|
||
@code{org-combined-agenda-icalendar-file}.
|
||

@vindex org-icalendar-include-body

@cindex property, SUMMARY
|

|

@cindex property, LOCATION
|

The export will honor SUMMARY, DESCRIPTION and LOCATION@footnote{The LOCATION
|
||
property can be inherited from higher in the hierarchy if you configure
|
||
@code{org-use-property-inheritance} accordingly.} properties if the selected
|
||
entries have them. If not, the summary will be derived from the headline,
|
||
and the description from the body (limited to
|
||
@code{org-icalendar-include-body} characters).
|
||
|
||
How this calendar is best read and updated, depends on the application
|
||
you are using. The FAQ covers this issue.

@cindex publishing
|
||
|
||
Org includes a publishing management system that allows you to configure
|
||
automatic HTML conversion of @emph{projects} composed of interlinked org
|
||
files. You can also configure Org to automatically upload your exported HTML
|
||
pages and related attachments, such as images and source code files, to a web
|
||
server.
|
||
|
||
You can also use Org to convert files into PDF, or even combine HTML and PDF
|
||
conversion so that files are available in both formats on the server.
|
||
|
||
Publishing has been contributed to Org by David O'Toole.

@subsection The variable @code{org-publish-project-alist}
|
||
@cindex org-publish-project-alist
|
||
@cindex projects, for publishing
|
||
|
||
@vindex org-publish-project-alist
|
||
Publishing is configured almost entirely through setting the value of one
|
||
variable, called @code{org-publish-project-alist}. Each element of the list
|
||
configures one project, and may be in one of the two following forms:
|
||
|
||
@lisp
|
||
("project-name" :property value :property value ...)
|
||
@r{i.e.@: a well-formed property list with alternating keys and values}
|
||
@r{or}
|
||
("project-name" :components ("project-name" "project-name" ...))
|
||
|
||
@end lisp
|
||
|
||
In both cases, projects are configured by specifying property values. A
|
||
project defines the set of files that will be published, as well as the
|
||
publishing configuration to use when publishing those files. When a project
|
||
takes the second form listed above, the individual members of the
|
||
@code{:components} property are taken to be sub-projects, which group
|
||
together files requiring different publishing options. When you publish such
|
||
a ``meta-project'', all the components will also be published, in the
|
||
sequence given.

@subsection Publishing action
|
||
@cindex action, for publishing
|
||
|
||
Publishing means that a file is copied to the destination directory and
|
||
possibly transformed in the process. The default transformation is to export
|
||
Org files as HTML files, and this is done by the function
|
||
@code{org-publish-org-to-html} which calls the HTML exporter (@pxref{HTML
|
||
export}). But you also can publish your content as PDF files using
|
||
@code{org-publish-org-to-pdf}, or as @code{ascii}, @code{latin1} or
|
||
@code{utf8} encoded files using the corresponding functions. If you want to
|
||
publish the Org file itself, but with @i{archived}, @i{commented}, and
|
||
@i{tag-excluded} trees removed, use @code{org-publish-org-to-org} and set the
|
||
parameters @code{:plain-source} and/or @code{:htmlized-source}. This will
|
||
produce @file{file.org} and @file{file.org.html} in the publishing
|
||
directory@footnote{@file{file-source.org} and @file{file-source.org.html} if
|
||
source and publishing directories are equal. Note that with this kind of
|
||
setup, you need to add @code{:exclude "-source\\.org"} to the project
|
||
definition in @code{org-publish-project-alist} to prevent the published
|
||
source files from being considered as new org files the next time the project
|
||
is published.}. Other files like images only need to be copied to the
|
||
publishing destination; for this you may use @code{org-publish-attachment}.
|
||
For non-Org files, you always need to specify the publishing function:
|
||
|
||
@multitable @columnfractions 0.3 0.7
|
||
@item @code{:publishing-function}
|
||
@tab Function executing the publication of a file. This may also be a
|
||
list of functions, which will all be called in turn.
|
||
@item @code{:plain-source}
|
||
@tab Non-nil means, publish plain source.
|
||
@item @code{:htmlized-source}
|
||
@tab Non-nil means, publish htmlized source.
|
||
@end multitable
|
||
|
||
The function must accept three arguments: a property list containing at least
|
||
a @code{:publishing-directory} property, the name of the file to be
|
||
published, and the path to the publishing directory of the output file. It
|
||
should take the specified file, make the necessary transformation (if any)
|
||
and place the result into the destination folder.

@subsection Links between published files
|
||
@cindex links, publishing
|
||
|
||
To create a link from one Org file to another, you would use
|
||
something like @samp{[[file:foo.org][The foo]]} or simply
|
||
@samp{file:foo.org.} (@pxref{Hyperlinks}). When published, this link
|
||
becomes a link to @file{foo.html}. In this way, you can interlink the
|
||
pages of your "org web" project and the links will work as expected when
|
||
you publish them to HTML. If you also publish the Org source file and want
|
||
to link to that, use an @code{http:} link instead of a @code{file:} link,
|
||
because @code{file:} links are converted to link to the corresponding
|
||
@file{html} file.
|
||
|
||
You may also link to related files, such as images. Provided you are careful
|
||
with relative file names, and provided you have also configured Org to upload
|
||
the related files, these links will work too. See @ref{Complex example}, for
|
||
an example of this usage.
|
||
|
||
Sometimes an Org file to be published may contain links that are
|
||
only valid in your production environment, but not in the publishing
|
||
location. In this case, use the property
|
||
|
||
@multitable @columnfractions 0.4 0.6
|
||
@item @code{:link-validation-function}
|
||
@tab Function to validate links
|
||
@end multitable
|
||
|
||
@noindent
|
||
to define a function for checking link validity. This function must
|
||
accept two arguments, the file name and a directory relative to which
|
||
the file name is interpreted in the production environment. If this
|
||
function returns @code{nil}, then the HTML generator will only insert a
|
||
description into the HTML file, but no link. One option for this
|
||
function is @code{org-publish-validate-link} which checks if the given
|
||
file is part of any project in @code{org-publish-project-alist}.

@tab How the files are sorted in the site map. Set this to

@code{alphabetically} (default), @code{chronologically} or

@code{anti-chronologically}. @code{chronologically} sorts the files with
|
||
older date first while @code{anti-chronologically} sorts the files with newer

a title, style information, etc.
|
||
|

@node Uploading files, Sample configuration, Configuration, Publishing
|
||
@section Uploading files
|
||
@cindex rsync
|
||
@cindex unison
|
||
|
||
For those people already utilizing third party sync tools such as
|
||
@command{rsync} or @command{unison}, it might be preferable not to use the built in
|
||
@i{remote} publishing facilities of Org mode which rely heavily on
|
||
Tramp. Tramp, while very useful and powerful, tends not to be
|
||
so efficient for multiple file transfer and has been known to cause problems
|
||
under heavy usage.
|
||
|
||
Specialized synchronization utilities offer several advantages. In addition
|
||
to timestamp comparison, they also do content and permissions/attribute
|
||
checks. For this reason you might prefer to publish your web to a local
|
||
directory (possibly even @i{in place} with your Org files) and then use
|
||
@file{unison} or @file{rsync} to do the synchronization with the remote host.
|
||
|
||
Since Unison (for example) can be configured as to which files to transfer to
|
||
a certain remote destination, it can greatly simplify the project publishing
|
||
definition. Simply keep all files in the correct location, process your Org
|
||
files with @code{org-publish} and let the synchronization tool do the rest.
|
||
You do not need, in this scenario, to include attachments such as @file{jpg},
|
||
@file{css} or @file{gif} files in the project definition since the 3rd party
|
||
tool syncs them.
|
||
|
||
Publishing to a local directory is also much faster than to a remote one, so
|
||
that you can afford more easily to republish entire projects. If you set
|
||
@code{org-publish-use-timestamps-flag} to @code{nil}, you gain the main
|
||
benefit of re-including any changed external files such as source example
|
||
files you might include with @code{#+INCLUDE}. The timestamp mechanism in
|
||
Org is not smart enough to detect if included files have been modified.

@subsection Example: complex publishing configuration
|
||
|
||
This more complicated example publishes an entire website, including
|
||
Org files converted to HTML, image files, Emacs Lisp source code, and
|
||
style sheets. The publishing directory is remote and private files are
|
||
excluded.
|
||
|
||
To ensure that links are preserved, care should be taken to replicate
|
||
your directory structure on the web server, and to use relative file
|
||
paths. For example, if your Org files are kept in @file{~/org} and your
|
||
publishable images in @file{~/images}, you would link to an image with
|
||
@c
|
||
@example
|
||
file:../images/myimage.png
|
||
@end example
|
||
@c
|
||
On the web server, the relative path to the image should be the
|
||
same. You can accomplish this by setting up an "images" folder in the
|
||
right place on the web server, and publishing images to it.

Org mode provides a number of features for working with live source code,
|
||
including editing of code blocks in their native major-mode, evaluation of
|
||
code blocks, converting code blocks into source files (known as @dfn{tangling}
|
||
in literate programming), and exporting code blocks and their
|
||
results in several formats. This functionality was contributed by Eric
|
||
Schulte and Dan Davison, and was originally named Org-babel.

inline.@footnote{Note that @samp{src} blocks may be inserted using Org mode's
|
||
@ref{Easy Templates} system} The structure of a @samp{src} block is

This line associates a name with the code block. This is similar to the

||
@code{#+TBLNAME: NAME} lines that can be used to name tables in Org mode
|
||
files. Referencing the name of a code block makes it possible to evaluate
|
||
the block from other places in the file, from other files, or from Org mode
|

and the behavior of Org mode when two or more blocks share the same name is

If an Emacs major-mode named @code{<lang>-mode} exists, where
|
||
@code{<lang>} is the language named in the header line of the code block,
|
||
then the edit buffer will be placed in that major-mode. This variable
|
||
can be used to map arbitrary language names to existing major modes.
|

@item org-src-window-setup
|
||
Controls the way Emacs windows are rearranged when the edit buffer is created.
|

@item org-src-preserve-indentation
|

This variable is especially useful for tangling languages such as
|
||
Python, in which whitespace indentation in the output is critical.
|
||
@item org-src-ask-before-returning-to-edit-buffer
|
||
By default, Org will ask before returning to an open edit buffer. Set this
|

It is possible to export the @emph{code} of code blocks, the @emph{results}
|
||
of code block evaluation, @emph{both} the code and the results of code block
|
||
evaluation, or @emph{none}. For most languages, the default exports code.
|
||
However, for some languages (e.g.@: @code{ditaa}) the default exports the
|
||
results of code block evaluation. For information on exporting code block
|
||
bodies, see @ref{Literal examples}.
|
||
|
||
The @code{:exports} header argument can be used to specify export
|
||
behavior:
|
||
|
||
@subsubheading Header arguments:
|
||
@table @code
|
||
@item :exports code
|
||
The default in most languages. The body of the code block is exported, as
|
||
described in @ref{Literal examples}.
|
||
@item :exports results
|
||
The code block will be evaluated and the results will be placed in the
|
||
Org mode buffer for export, either updating previous results of the code
|
||
block located anywhere in the buffer or, if no previous results exist,
|
||
placing the results immediately after the code block. The body of the code
|
||
block will not be exported.
|
||
@item :exports both
|
||
Both the code block and its results will be exported.
|
||
@item :exports none
|
||
Neither the code block nor its results will be exported.
|
||
@end table
|
||
|
||
It is possible to inhibit the evaluation of code blocks during export.
|
||
Setting the @code{org-export-babel-evaluate} variable to @code{nil} will
|
||
ensure that no code blocks are evaluated as part of the export process. This
|
||
can be useful in situations where potentially untrusted Org mode files are
|
||
exported in an automated fashion, for example when Org mode is used as the
|
||
markup language for a wiki.

@cindex #+RESULTS
|
||
|
||
Code blocks can be evaluated@footnote{Whenever code is evaluated there is a
|
||
potential for that code to do harm. Org mode provides safeguards to ensure
|
||
that code is only evaluated after explicit confirmation from the user. For
|
||
information on these safeguards (and on how to disable them) see @ref{Code
|
||
evaluation security}.} and the results of evaluation optionally placed in the
|
||
Org mode buffer. The results of evaluation are placed following a line that
|
||
begins by default with @code{#+RESULTS} and optionally a cache identifier
|
||
and/or the name of the evaluated code block. The default value of
|
||
@code{#+RESULTS} can be changed with the customizable variable
|
||
@code{org-babel-results-keyword}.
|
||
|
||
By default, the evaluation facility is only enabled for Lisp code blocks
|
||
specified as @code{emacs-lisp}. However, source code blocks in many languages
|
||
can be evaluated within Org mode (see @ref{Languages} for a list of supported
|
||
languages and @ref{Structure of code blocks} for information on the syntax
|
||
used to define a code block).
|
||
|
||
@kindex C-c C-c
|
||
There are a number of ways to evaluate code blocks. The simplest is to press
|
||
@kbd{C-c C-c} or @kbd{C-c C-v e} with the point on a code block@footnote{The
|
||
@code{org-babel-no-eval-on-ctrl-c-ctrl-c} variable can be used to remove code
|
||
evaluation from the @kbd{C-c C-c} key binding.}. This will call the
|
||
@code{org-babel-execute-src-block} function to evaluate the block and insert
|
||
its results into the Org mode buffer.
|
||
@cindex #+CALL
|
||
|
||
It is also possible to evaluate named code blocks from anywhere in an
|
||
Org mode buffer or an Org mode table. Live code blocks located in the current
|
||
Org mode buffer or in the ``Library of Babel'' (see @ref{Library of Babel})
|
||
can be executed. Named code blocks can be executed with a separate
|
||
@code{#+CALL:} line or inline within a block of text.
|
||
|
||
The syntax of the @code{#+CALL:} line is
|
||
|
||
@example
|
||
#+CALL: <name>(<arguments>)
|
||
#+CALL: <name>[<inside header arguments>](<arguments>) <end header arguments>
|
||
@end example
|
||
|
||
The syntax for inline evaluation of named code blocks is
|
||
|
||
@example
|
||
... call_<name>(<arguments>) ...
|
||
... call_<name>[<inside header arguments>](<arguments>)[<end header arguments>] ...
|
||
@end example
|
||
|
||
@table @code
|
||
@item <name>
|
||
The name of the code block to be evaluated (see @ref{Structure of code blocks}).
|
||
@item <arguments>
|
||
Arguments specified in this section will be passed to the code block. These
|
||
arguments use standard function call syntax, rather than
|
||
header argument syntax. For example, a @code{#+CALL:} line that passes the
|
||
number four to a code block named @code{double}, which declares the header
|
||
argument @code{:var n=2}, would be written as @code{#+CALL: double(n=4)}.
|
||
@item <inside header arguments>
|
||
Inside header arguments are passed through and applied to the named code
|
||
block. These arguments use header argument syntax rather than standard
|
||
function call syntax. Inside header arguments affect how the code block is
|
||
evaluated. For example, @code{[:results output]} will collect the results of
|
||
everything printed to @code{STDOUT} during execution of the code block.
|
||
@item <end header arguments>
|
||
End header arguments are applied to the calling instance and do not affect
|
||
evaluation of the named code block. They affect how the results are
|
||
incorporated into the Org mode buffer and how the call line is exported. For
|
||
example, @code{:results html} will insert the results of the call line
|
||
evaluation in the Org buffer, wrapped in a @code{BEGIN_HTML:} block.
|
||
|
||

@subsubheading Buffer-wide header arguments
|
||
Buffer-wide header arguments may be specified as properties through the use
|
||
of @code{#+PROPERTY:} lines placed anywhere in an Org mode file (see
|
||
@ref{Property syntax}).
|
||
|
||
For example the following would set @code{session} to @code{*R*}, and
|
||
@code{results} to @code{silent} for every code block in the buffer, ensuring
|
||
that all execution took place in the same session, and no results would be
|
||
inserted into the buffer.
|
||
|

@example
|
||
#+PROPERTY: session *R*
|
||
#+PROPERTY: results silent

@node Header arguments in Org mode properties, Code block specific header arguments, Buffer-wide header arguments, Using header arguments

@subsubheading Header arguments in Org mode properties
|
||
|
||
Header arguments are also read from Org mode properties (see @ref{Property
|
||
syntax}), which can be set on a buffer-wide or per-heading basis. An example
|
||
of setting a header argument for all code blocks in a buffer is
|
||
|
||
@example
|
||
#+PROPERTY: tangle yes
|
||
@end example
|
||
|
||
@vindex org-use-property-inheritance
|
||
When properties are used to set default header arguments, they are looked up
|
||
with inheritance, regardless of the value of
|
||
@code{org-use-property-inheritance}. In the following example the value of
|
||
the @code{:cache} header argument will default to @code{yes} in all code
|
||
blocks in the subtree rooted at the following heading:
|
||
|
||
@example
|
||
* outline header

|

@vindex org-babel-default-header-args
|

Properties defined in this way override the properties set in
|
||
@code{org-babel-default-header-args}. It is convenient to use the
|
||
@code{org-set-property} function bound to @kbd{C-c C-x p} to set properties
|
||
in Org mode documents.

|
||
@node Code block specific header arguments, Header arguments in function calls, Header arguments in Org mode properties, Using header arguments

||
@subsubheading Code block specific header arguments
|
||
|
||
The most common way to assign values to header arguments is at the
|
||
code block level. This can be done by listing a sequence of header
|
||
arguments and their values as part of the @code{#+BEGIN_SRC} line.
|
||
Properties set in this way override both the values of
|
||
@code{org-babel-default-header-args} and header arguments specified as
|
||
properties. In the following example, the @code{:results} header argument
|
||
is set to @code{silent}, meaning the results of execution will not be
|
||
inserted in the buffer, and the @code{:exports} header argument is set to
|
||
@code{code}, meaning only the body of the code block will be
|
||
preserved on export to HTML or @LaTeX{}.
|
||
|
||
@example
|
||
#+NAME: factorial
|
||
#+BEGIN_SRC haskell :results silent :exports code :var n=0
|
||
fac 0 = 1
|
||
fac n = n * fac (n-1)
|
||
#+END_SRC
|
||
@end example
|
||
Similarly, it is possible to set header arguments for inline code blocks
|
||
|
||
@example
|
||
src_haskell[:exports both]@{fac 5@}
|
||
@end example
|
||
|
||
Code block header arguments can span multiple lines using @code{#+HEADER:} or
|
||
@code{#+HEADERS:} lines preceding a code block or nested between the
|
||
@code{#+NAME:} line and the @code{#+BEGIN_SRC} line of a named code block.
|
||
@cindex #+HEADER:
|
||
@cindex #+HEADERS:

|
||
(message "data1:%S, data2:%S" data1 data2)
|
||
#+END_SRC

||
|
||
#+results:
|
||

syntax used to specify arguments is the same across all languages. In every
|
||
case, variables require a default value when they are declared.
|
||
|
||
The values passed to arguments can either be literal values, references, or
|
||
Emacs Lisp code (see @ref{var, Emacs Lisp evaluation of variables}). References
|
||
include anything in the Org mode file that takes a @code{#+NAME:},
|
||
@code{#+TBLNAME:}, or @code{#+RESULTS:} line. This includes tables, lists,
|
||
@code{#+BEGIN_EXAMPLE} blocks, other code blocks, and the results of other
|
||
code blocks.
|
||
|
||
Argument values can be indexed in a manner similar to arrays (see @ref{var,
|
||
Indexable variable values}).
|
||
|
||
The following syntax is used to pass arguments to code blocks using the
|
||
@code{:var} header argument.
|
||
|
||
@example
|
||
:var name=assign
|
||
@end example
|
||
|
||
The argument, @code{assign}, can either be a literal value, such as a string
|
||
@samp{"string"} or a number @samp{9}, or a reference to a table, a list, a
|
||
literal example, another code block (with or without arguments), or the
|
||
results of evaluating another code block.
|
||
|
||
Here are examples of passing values by reference:
|
||
|
||
@table @dfn
|
||
|
||
@item table
|
||
an Org mode table named with either a @code{#+NAME:} or @code{#+TBLNAME:} line
|
||
@example
|
||
#+TBLNAME: example-table
|
||
| 1 |
|
||
| 2 |
|
||
| 3 |
|
||
| 4 |
|
||
|
||
#+NAME: table-length
|
||
#+BEGIN_SRC emacs-lisp :var table=example-table
|
||
(length table)
|
||
#+END_SRC
|
||
|
||
#+results: table-length
|
||
: 4
|
||
@end example
|
||
|
||
@item list
|
||
a simple list named with a @code{#+NAME:} line (note that nesting is not
|
||
carried through to the source code block)
|
||
|
||
@example
|
||
#+NAME: example-list
|
||
- simple
|
||
- not
|
||
- nested
|
||
- list
|
||
|
||
#+BEGIN_SRC emacs-lisp :var x=example-list
|
||
(print x)
|
||
#+END_SRC
|
||
|
||
#+results:
|
||
| simple | list |
|
||
@end example
|
||
|
||
@item code block without arguments
|
||
a code block name (from the example above), as assigned by @code{#+NAME:},
|
||
optionally followed by parentheses
|
||
|
||
@example
|
||
#+BEGIN_SRC emacs-lisp :var length=table-length()
|
||
(* 2 length)
|
||
#+END_SRC
|
||
|
||
#+results:
|
||
: 8
|
||
@end example
|
||
|
||
@item code block with arguments
|
||
a code block name, as assigned by @code{#+NAME:}, followed by parentheses and
|
||
optional arguments passed within the parentheses following the
|
||
code block name using standard function call syntax
|
||
|
||
@example
|
||
#+NAME: double
|
||
#+BEGIN_SRC emacs-lisp :var input=8
|
||
(* 2 input)
|
||
#+END_SRC
|
||
|
||
#+results: double
|
||
: 16
|
||
|
||
#+NAME: squared
|
||
#+BEGIN_SRC emacs-lisp :var input=double(input=1)
|
||
(* input input)
|
||
#+END_SRC
|
||
|
||
#+results: squared
|
||
: 4
|
||
@end example
|
||
|
||
@item literal example
|
||
a literal example block named with a @code{#+NAME:} line
|
||
|
||
@example
|
||
#+NAME: literal-example
|
||
#+BEGIN_EXAMPLE
|
||
A literal example
|
||
on two lines
|
||
#+END_EXAMPLE
|
||
|
||
#+NAME: read-literal-example
|
||
#+BEGIN_SRC emacs-lisp :var x=literal-example
|
||
(concatenate 'string x " for you.")
|
||
#+END_SRC
|
||
|
||
#+results: read-literal-example
|
||
: A literal example
|
||
: on two lines for you.
|
||
|
||
@end example
|
||
|
||
@end table
|
||
|
||
@subsubheading Alternate argument syntax
|
||
It is also possible to specify arguments in a potentially more natural way
|
||
using the @code{#+NAME:} line of a code block. As in the following
|
||
example, arguments can be packed inside of parentheses, separated by commas,
|
||
following the source name.
|
||
|
||
@example
|
||
#+NAME: double(input=0, x=2)
|
||
#+BEGIN_SRC emacs-lisp
|
||
(* 2 (+ input x))
|
||
#+END_SRC
|
||
@end example
|
||
|
||
@subsubheading Indexable variable values
|
||
It is possible to reference portions of variable values by ``indexing'' into
|
||
the variables. Indexes are 0 based with negative values counting back from
|
||
the end. If an index is separated by @code{,}s then each subsequent section
|
||
will index into the next deepest nesting or dimension of the value. Note
|
||
that this indexing occurs @emph{before} other table related header arguments
|
||
like @code{:hlines}, @code{:colnames} and @code{:rownames} are applied. The
|
||
following example assigns the last cell of the first row the table
|
||
@code{example-table} to the variable @code{data}:
|
||
|
||
@example
|
||
#+NAME: example-table
|
||
| 1 | a |
|
||
| 2 | b |
|
||
| 3 | c |
|
||
| 4 | d |
|
||
|
||
#+BEGIN_SRC emacs-lisp :var data=example-table[0,-1]
|
||
data
|
||
#+END_SRC
|
||
|
||
#+results:
|
||
: a
|
||
@end example
|
||
|
||
Ranges of variable values can be referenced using two integers separated by a
|
||
@code{:}, in which case the entire inclusive range is referenced. For
|
||
example the following assigns the middle three rows of @code{example-table}
|
||
to @code{data}.
|
||
|
||
@example
|
||
#+NAME: example-table
|
||
| 1 | a |
|
||
| 2 | b |
|
||
| 3 | c |
|
||
| 4 | d |
|
||
| 5 | 3 |
|
||
|
||
#+BEGIN_SRC emacs-lisp :var data=example-table[1:3]
|
||
data
|
||
#+END_SRC
|
||
|
||
#+results:
|
||
| 2 | b |
|
||
| 3 | c |
|
||
| 4 | d |
|
||
@end example
|
||
|
||
Additionally, an empty index, or the single character @code{*}, are both
|
||
interpreted to mean the entire range and as such are equivalent to
|
||
@code{0:-1}, as shown in the following example in which the entire first
|
||
column is referenced.
|
||
|
||
@example
|
||
#+NAME: example-table
|
||
| 1 | a |
|
||
| 2 | b |
|
||
| 3 | c |
|
||
| 4 | d |
|
||
|
||
#+BEGIN_SRC emacs-lisp :var data=example-table[,0]
|
||
data
|
||
#+END_SRC
|
||
|
||
#+results:
|
||
| 1 | 2 | 3 | 4 |
|
||
@end example
|
||
|
||
It is possible to index into the results of code blocks as well as tables.
|
||
Any number of dimensions can be indexed. Dimensions are separated from one
|
||
another by commas, as shown in the following example.
|
||
|
||
@example
|
||
#+NAME: 3D
|
||
#+BEGIN_SRC emacs-lisp
|
||
'(((1 2 3) (4 5 6) (7 8 9))
|
||
((10 11 12) (13 14 15) (16 17 18))
|
||
((19 20 21) (22 23 24) (25 26 27)))
|
||
#+END_SRC
|
||
|
||
#+BEGIN_SRC emacs-lisp :var data=3D[1,,1]
|
||
data
|
||
#+END_SRC
|
||
|
||
#+results:
|
||
| 11 | 14 | 17 |
|

||
@subsubheading Emacs Lisp evaluation of variables
|
||
|
||
Emacs lisp code can be used to initialize variable values. When a variable
|
||
value starts with @code{(}, @code{[}, @code{'} or @code{`} it will be
|
||
evaluated as Emacs Lisp and the result of the evaluation will be assigned as
|
||
the variable value. The following example demonstrates use of this
|
||
evaluation to reliably pass the file-name of the Org mode buffer to a code
|
||
block---note that evaluation of header arguments is guaranteed to take place
|
||
in the original Org mode file, while there is no such guarantee for
|
||
evaluation of the code block body.
|
||
|
||
@example
|
||
#+BEGIN_SRC sh :var filename=(buffer-file-name) :exports both
|
||
wc -w $filename
|
||
#+END_SRC
|
||
@end example
|
||
|
||
Note that values read from tables and lists will not be evaluated as
|
||
Emacs Lisp, as shown in the following example.
|
||
|
||
@example
|
||
#+NAME: table
|
||
| (a b c) |
|
||
|
||
#+HEADERS: :var data=table[0,0]
|
||
#+BEGIN_SRC perl
|
||
$data
|
||
#+END_SRC
|
||
|
||
#+results:
|
||
: (a b c)
|
||
@end example
|
||
|
||
@node results, file, var, Specific header arguments
|
||
@subsubsection @code{:results}
|
||
|
||
There are three classes of @code{:results} header argument. Only one option
|
||
per class may be supplied per code block.
|
||
|
||
@itemize @bullet
|
||
@item
|
||
@b{collection} header arguments specify how the results should be collected
|
||
from the code block
|
||
@item
|
||
@b{type} header arguments specify what type of result the code block will
|
||
return---which has implications for how they will be inserted into the
|
||
Org mode buffer
|
||
@item
|
||
@b{handling} header arguments specify how the results of evaluating the code
|
||
block should be handled.
|
||
@end itemize
|
||
|
||
@subsubheading Collection
|
||
The following options are mutually exclusive, and specify how the results
|
||
should be collected from the code block.
|
||
|
||
@itemize @bullet
|
||
@item @code{value}
|
||
This is the default. The result is the value of the last statement in the
|
||
code block. This header argument places the evaluation in functional
|
||
mode. Note that in some languages, e.g., Python, use of this result type
|
||
requires that a @code{return} statement be included in the body of the source
|
||
code block. E.g., @code{:results value}.
|
||
@item @code{output}
|
||
The result is the collection of everything printed to STDOUT during the
|
||
execution of the code block. This header argument places the
|
||
evaluation in scripting mode. E.g., @code{:results output}.
|
||
@end itemize
|
||
|
||
@subsubheading Type
|
||
|
||
The following options are mutually exclusive and specify what type of results
|
||
the code block will return. By default, results are inserted as either a
|
||
table or scalar depending on their value.
|
||
|
||
@itemize @bullet
|
||
@item @code{table}, @code{vector}
|
||
The results should be interpreted as an Org mode table. If a single value is
|
||
returned, it will be converted into a table with one row and one column.
|
||
E.g., @code{:results value table}.
|
||
@item @code{list}
|
||
The results should be interpreted as an Org mode list. If a single scalar
|
||
value is returned it will be converted into a list with only one element.
|
||
@item @code{scalar}, @code{verbatim}
|
||
The results should be interpreted literally---they will not be
|
||
converted into a table. The results will be inserted into the Org mode
|
||
buffer as quoted text. E.g., @code{:results value verbatim}.
|
||
@item @code{file}
|
||
The results will be interpreted as the path to a file, and will be inserted
|
||
into the Org mode buffer as a file link. E.g., @code{:results value file}.
|
||
@item @code{raw}, @code{org}
|
||
The results are interpreted as raw Org mode code and are inserted directly
|
||
into the buffer. If the results look like a table they will be aligned as
|
||
such by Org mode. E.g., @code{:results value raw}.
|
||
@item @code{html}
|
||
Results are assumed to be HTML and will be enclosed in a @code{begin_html}
|
||
block. E.g., @code{:results value html}.
|
||
@item @code{latex}
|
||
Results assumed to be @LaTeX{} and are enclosed in a @code{begin_latex} block.
|
||
E.g., @code{:results value latex}.
|
||
@item @code{code}
|
||
Result are assumed to be parsable code and are enclosed in a code block.
|
||
E.g., @code{:results value code}.
|
||
@item @code{pp}
|
||
The result is converted to pretty-printed code and is enclosed in a code
|
||
block. This option currently supports Emacs Lisp, Python, and Ruby. E.g.,
|
||
@code{:results value pp}.
|
||
@item @code{wrap}
|
||
The result is wrapped in a RESULTS drawer. This can be useful for
|
||
inserting @code{raw} or @code{org} syntax results in such a way that their
|
||
extent is known and they can be automatically removed or replaced.
|
||
@end itemize
|
||
|
||
@subsubheading Handling
|
||
The following results options indicate what happens with the
|
||
results once they are collected.
|
||
|
||
@itemize @bullet
|
||
@item @code{silent}
|
||
The results will be echoed in the minibuffer but will not be inserted into
|
||
the Org mode buffer. E.g., @code{:results output silent}.
|
||
@item @code{replace}
|
||
The default value. Any existing results will be removed, and the new results
|
||
will be inserted into the Org mode buffer in their place. E.g.,
|
||
@code{:results output replace}.
|
||
@item @code{append}
|
||
If there are pre-existing results of the code block then the new results will
|
||
be appended to the existing results. Otherwise the new results will be
|
||
inserted as with @code{replace}.
|
||
@item @code{prepend}
|
||
If there are pre-existing results of the code block then the new results will
|
||
be prepended to the existing results. Otherwise the new results will be
|
||
inserted as with @code{replace}.
|
||
@end itemize
|
||
|
||
@node file, dir, results, Specific header arguments
|
||
@subsubsection @code{:file}
|
||
|
||
The header argument @code{:file} is used to specify an external file in which
|
||
to save code block results. After code block evaluation an Org mode style
|
||
@code{[[file:]]} link (see @ref{Link format}) to the file will be inserted
|
||
into the Org mode buffer. Some languages including R, gnuplot, dot, and
|
||
ditaa provide special handling of the @code{:file} header argument
|
||
automatically wrapping the code block body in the boilerplate code required
|
||
to save output to the specified file. This is often useful for saving
|
||
graphical output of a code block to the specified file.
|
||
|
||
The argument to @code{:file} should be either a string specifying the path to
|
||
a file, or a list of two strings in which case the first element of the list
|
||
should be the path to a file and the second a description for the link.
|
||
|
||
@node dir, exports, file, Specific header arguments
|
||
@subsubsection @code{:dir} and remote execution
|
||
|
||
While the @code{:file} header argument can be used to specify the path to the
|
||
output file, @code{:dir} specifies the default directory during code block
|
||
execution. If it is absent, then the directory associated with the current
|
||
buffer is used. In other words, supplying @code{:dir path} temporarily has
|
||
the same effect as changing the current directory with @kbd{M-x cd path}, and
|
||
then not supplying @code{:dir}. Under the surface, @code{:dir} simply sets
|
||
the value of the Emacs variable @code{default-directory}.
|
||
|
||
When using @code{:dir}, you should supply a relative path for file output
|
||
(e.g.@: @code{:file myfile.jpg} or @code{:file results/myfile.jpg}) in which
|
||
case that path will be interpreted relative to the default directory.
|
||
|
||
In other words, if you want your plot to go into a folder called @file{Work}
|
||
in your home directory, you could use
|
||
|
||
@example
|
||
#+BEGIN_SRC R :file myplot.png :dir ~/Work
|
||
matplot(matrix(rnorm(100), 10), type="l")
|
||
#+END_SRC
|
||
@end example
|
||
|
||
@subsubheading Remote execution
|
||
A directory on a remote machine can be specified using tramp file syntax, in
|
||
which case the code will be evaluated on the remote machine. An example is
|
||
|
||
@example
|
||
#+BEGIN_SRC R :file plot.png :dir /dand@@yakuba.princeton.edu:
|
||
plot(1:10, main=system("hostname", intern=TRUE))
|
||
#+END_SRC
|
||
@end example
|
||
|
||
Text results will be returned to the local Org mode buffer as usual, and file
|
||
output will be created on the remote machine with relative paths interpreted
|
||
relative to the remote directory. An Org mode link to the remote file will be
|
||
created.
|
||
|
||
So, in the above example a plot will be created on the remote machine,
|
||
and a link of the following form will be inserted in the org buffer:
|
||
|
||
@example
|
||
[[file:/scp:dand@@yakuba.princeton.edu:/home/dand/plot.png][plot.png]]
|
||
@end example
|
||
|
||
Most of this functionality follows immediately from the fact that @code{:dir}
|
||
sets the value of the Emacs variable @code{default-directory}, thanks to
|
||
tramp. Those using XEmacs, or GNU Emacs prior to version 23 may need to
|
||
install tramp separately in order for these features to work correctly.
|
||
|
||
@subsubheading Further points
|
||
|
||
@itemize @bullet
|
||
@item
|
||
If @code{:dir} is used in conjunction with @code{:session}, although it will
|
||
determine the starting directory for a new session as expected, no attempt is
|
||
currently made to alter the directory associated with an existing session.
|
||
@item
|
||
@code{:dir} should typically not be used to create files during export with
|
||
@code{:exports results} or @code{:exports both}. The reason is that, in order
|
||
to retain portability of exported material between machines, during export
|
||
links inserted into the buffer will @emph{not} be expanded against @code{default
|
||
directory}. Therefore, if @code{default-directory} is altered using
|
||
@code{:dir}, it is probable that the file will be created in a location to
|
||
which the link does not point.
|
||
@end itemize
|
||
|
||
@node exports, tangle, dir, Specific header arguments
|
||
@subsubsection @code{:exports}
|
||
|
||
The @code{:exports} header argument specifies what should be included in HTML
|
||
or @LaTeX{} exports of the Org mode file.
|
||
|
||
@itemize @bullet
|
||
@item @code{code}
|
||
The default. The body of code is included into the exported file. E.g.,
|
||
@code{:exports code}.
|
||
@item @code{results}
|
||
The result of evaluating the code is included in the exported file. E.g.,
|
||
@code{:exports results}.
|
||
@item @code{both}
|
||
Both the code and results are included in the exported file. E.g.,
|
||
@code{:exports both}.
|
||
@item @code{none}
|
||
Nothing is included in the exported file. E.g., @code{:exports none}.
|
||
@end itemize
|
||
|
||
@node tangle, mkdirp, exports, Specific header arguments
|
||
@subsubsection @code{:tangle}
|
||
|
||
The @code{:tangle} header argument specifies whether or not the code
|
||
block should be included in tangled extraction of source code files.
|
||
|
||
@itemize @bullet
|
||
@item @code{tangle}
|
||
The code block is exported to a source code file named after the full path
|
||
(including the directory) and file name (w/o extension) of the Org mode file.
|
||
E.g., @code{:tangle yes}.
|
||
@item @code{no}
|
||
The default. The code block is not exported to a source code file.
|
||
E.g., @code{:tangle no}.
|
||
@item other
|
||
Any other string passed to the @code{:tangle} header argument is interpreted
|
||
as a path (directory and file name relative to the directory of the Org mode
|
||
file) to which the block will be exported. E.g., @code{:tangle path}.
|
||
@end itemize
|
||
|
||
@node mkdirp, comments, tangle, Specific header arguments
|
||
@subsubsection @code{:mkdirp}
|
||
|
||
The @code{:mkdirp} header argument can be used to create parent directories
|
||
of tangled files when missing. This can be set to @code{yes} to enable
|
||
directory creation or to @code{no} to inhibit directory creation.
|
||
|
||
@node comments, padline, mkdirp, Specific header arguments
|
||
@subsubsection @code{:comments}
|
||
By default code blocks are tangled to source-code files without any insertion
|
||
of comments beyond those which may already exist in the body of the code
|
||
block. The @code{:comments} header argument can be set as follows to control
|
||
the insertion of extra comments into the tangled code file.
|
||
|
||
@itemize @bullet
|
||
@item @code{no}
|
||
The default. No extra comments are inserted during tangling.
|
||
@item @code{link}
|
||
The code block is wrapped in comments which contain pointers back to the
|
||
original Org file from which the code was tangled.
|
||
@item @code{yes}
|
||
A synonym for ``link'' to maintain backwards compatibility.
|
||
@item @code{org}
|
||
Include text from the Org mode file as a comment.
|
||
|
||
The text is picked from the leading context of the tangled code and is
|
||
limited by the nearest headline or source block as the case may be.
|

Control in insertion of padding lines around code block bodies in tangled

are accepted.
|

@subsubsection @code{:no-expand}
|
||
|
||
By default, code blocks are expanded with @code{org-babel-expand-src-block}
|
||
during tangling. This has the effect of assigning values to variables
|
||
specified with @code{:var} (see @ref{var}), and of replacing ``noweb''
|
||
references (see @ref{Noweb reference syntax}) with their targets. The
|
||
@code{:no-expand} header argument can be used to turn off this behavior.
|

|

@node session, noweb, no-expand, Specific header arguments
|

@subsubsection @code{:session}
|
||
|
||
The @code{:session} header argument starts a session for an interpreted
|
||
language where state is preserved.
|
||
|
||
By default, a session is not started.
|
||
|
||
A string passed to the @code{:session} header argument will give the session
|
||
a name. This makes it possible to run concurrent sessions for each
|
||
interpreted language.
|
||
|
||
@node noweb, noweb-ref, session, Specific header arguments
|

@subsubsection @code{:noweb}
|
||
|
||
The @code{:noweb} header argument controls expansion of ``noweb'' style (see
|
||
@ref{Noweb reference syntax}) references in a code block. This header
|
||
argument can have one of three values: @code{yes}, @code{no}, or @code{tangle}.
|
||
|
||
@itemize @bullet
|
||
@item @code{yes}
|
||
All ``noweb'' syntax references in the body of the code block will be
|
||
expanded before the block is evaluated, tangled or exported.
|
||
@item @code{no}
|
||
The default. No ``noweb'' syntax specific action is taken when the code
|
||
block is evaluated, tangled or exported.
|
||
@item @code{tangle}
|
||
All ``noweb'' syntax references in the body of the code block will be
|
||
expanded before the block is tangled, however ``noweb'' references will not
|
||
be expanded when the block is evaluated or exported.
|
||
@end itemize
|
||
|
||
@subsubheading Noweb prefix lines
|
||
Noweb insertions are now placed behind the line prefix of the
|
||
@code{<<reference>>}.
|
||
This behavior is illustrated in the following example. Because the
|
||
@code{<<example>>} noweb reference appears behind the SQL comment syntax,
|
||
each line of the expanded noweb reference will be commented.
|
||
|
||
This code block:
|
||
|
||
@example
|
||
-- <<example>>
|
||
@end example
|
||
|
||
|
||
expands to:
|
||
|
||
@example
|
||
-- this is the
|
||
-- multi-line body of example
|
||
@end example
|
||
|
||
Note that noweb replacement text that does not contain any newlines will not
|
||
be affected by this change, so it is still possible to use inline noweb
|
||
references.

||
@node noweb-ref, noweb-sep, noweb, Specific header arguments

@subsubsection @code{:noweb-ref}
|
||
When expanding ``noweb'' style references the bodies of all code block with
|
||
@emph{either} a block name matching the reference name @emph{or} a
|
||
@code{:noweb-ref} header argument matching the reference name will be
|
||
concatenated together to form the replacement text.
|
||
|
||
By setting this header argument at the sub-tree or file level, simple code
|
||
block concatenation may be achieved. For example, when tangling the
|
||
following Org mode file, the bodies of code blocks will be concatenated into
|
||
the resulting pure code file@footnote{(The example needs property inheritance
|
||
to be turned on for the @code{noweb-ref} property, see @ref{Property
|
||
inheritance}).}.

@node cache, sep, noweb-sep, Specific header arguments
|
||
@subsubsection @code{:cache}
|
||
|
||
The @code{:cache} header argument controls the use of in-buffer caching of
|
||
the results of evaluating code blocks. It can be used to avoid re-evaluating
|
||
unchanged code blocks. Note that the @code{:cache} header argument will not
|
||
attempt to cache results when the @code{:session} header argument is used,
|
||
because the results of the code block execution may be stored in the session
|
||
outside of the Org-mode buffer. The @code{:cache} header argument can have
|
||
one of two values: @code{yes} or @code{no}.
|
||
|
||
@itemize @bullet
|
||
@item @code{no}
|
||
The default. No caching takes place, and the code block will be evaluated
|
||
every time it is called.
|
||
@item @code{yes}
|
||
Every time the code block is run a SHA1 hash of the code and arguments
|
||
passed to the block will be generated. This hash is packed into the
|
||
@code{#+results:} line and will be checked on subsequent
|
||
executions of the code block. If the code block has not
|
||
changed since the last time it was evaluated, it will not be re-evaluated.
|
||
@end itemize
|
||
|
||
Code block caches notice if the value of a variable argument
|
||
to the code block has changed. If this is the case, the cache is
|
||
invalidated and the code block is re-run. In the following example,
|
||
@code{caller} will not be re-run unless the results of @code{random} have
|
||
changed since it was last run.

@subsubsection @code{:sep}
|
||
|
||
The @code{:sep} header argument can be used to control the delimiter used
|
||
when writing tabular results out to files external to Org mode. This is used
|
||
either when opening tabular results of a code block by calling the
|
||
@code{org-open-at-point} function bound to @kbd{C-c C-o} on the code block,
|
||
or when writing code block results to an external file (see @ref{file})
|
||
header argument.
|
||
|
||
By default, when @code{:sep} is not specified output tables are tab
|
||
delimited.
|
||
|
||
@node hlines, colnames, sep, Specific header arguments
|
||
@subsubsection @code{:hlines}
|
||
|
||
Tables are frequently represented with one or more horizontal lines, or
|
||
hlines. The @code{:hlines} argument to a code block accepts the
|
||
values @code{yes} or @code{no}, with a default value of @code{no}.
|
||
|
||
@itemize @bullet
|
||
@item @code{no}
|
||
Strips horizontal lines from the input table. In most languages this is the
|
||
desired effect because an @code{hline} symbol is interpreted as an unbound
|
||
variable and raises an error. Setting @code{:hlines no} or relying on the
|
||
default value yields the following results.
|
||
|
||
@example
|
||
#+TBLNAME: many-cols
|
||
| a | b | c |
|
||
|---+---+---|
|

| g | h | i |
|

@end example
|

Leaves hlines in the table. Setting @code{:hlines yes} has this effect.

@subsubsection @code{:colnames}
|

|
||
The @code{:colnames} header argument accepts the values @code{yes},
|
||
@code{no}, or @code{nil} for unassigned. The default value is @code{nil}.
|
||
Note that the behavior of the @code{:colnames} header argument may differ
|
||
across languages. For example Emacs Lisp code blocks ignore the
|
||
@code{:colnames} header argument entirely given the ease with which tables
|
||
with column names may be handled directly in Emacs Lisp.
|
||
|
||
@itemize @bullet
|
||
@item @code{nil}
|
||
If an input table looks like it has column names
|
||
(because its second row is an hline), then the column
|
||
names will be removed from the table before
|
||
processing, then reapplied to the results.
|
||
|
||
@example
|

#+TBLNAME: less-cols

Setting the @code{:shebang} header argument to a string value

(e.g.@: @code{:shebang "#!/bin/bash"}) causes the string to be inserted as the

@node eval, , shebang, Specific header arguments

@subsubsection @code{:eval}
|
||
The @code{:eval} header argument can be used to limit the evaluation of
|

specific code blocks. The @code{:eval} header argument can be useful for
|
||
protecting against the evaluation of dangerous code blocks or to ensure that
|
||
evaluation will require a query regardless of the value of the
|
||
@code{org-confirm-babel-evaluate} variable. The possible values of
|
||
@code{:eval} and their effects are shown below.
|
||
|
||
@table @code
|
||
@item never or no
|
||
The code block will not be evaluated under any circumstances.
|
||
@item query
|
||
Evaluation of the code block will require a query.
|

@item never-export or no-export
|
||
The code block will not be evaluated during export but may still be called

||
interactively.
|
||
@item query-export
|
||
Evaluation of the code block during export will require a query.
|
||
@end table
|

If this header argument is not set then evaluation is determined by the value

The way in which results are handled depends on whether a session is invoked,

used. The following table shows the table possibilities. For a full listing

Note: With @code{:results value}, the result in both @code{:session} and

non-session is returned to Org mode as a table (a one- or two-dimensional
|
||
vector of strings or numbers) when appropriate.
|
||
|
||
@subsection Non-session
|
||
@subsubsection @code{:results value}
|
||
This is the default. Internally, the value is obtained by wrapping the code
|
||
in a function definition in the external language, and evaluating that
|
||
function. Therefore, code should be written as if it were the body of such a
|
||
function. In particular, note that Python does not automatically return a
|
||
value from a function unless a @code{return} statement is present, and so a
|
||
@samp{return} statement will usually be required in Python.
|
||
|
||
This is the only one of the four evaluation contexts in which the code is
|
||
automatically wrapped in a function definition.
|
||
|
||
@subsubsection @code{:results output}
|
||
The code is passed to the interpreter as an external process, and the
|
||
contents of the standard output stream are returned as text. (In certain
|
||
languages this also contains the error output stream; this is an area for
|
||
future work.)
|
||
|
||
@subsection Session
|
||
@subsubsection @code{:results value}
|
||
The code is passed to an interpreter running as an interactive Emacs inferior
|
||
process. Only languages which provide tools for interactive evaluation of
|
||
code have session support, so some language (e.g., C and ditaa) do not
|
||
support the @code{:session} header argument, and in other languages (e.g.,
|
||
Python and Haskell) which have limitations on the code which may be entered
|
||
into interactive sessions, those limitations apply to the code in code blocks
|
||
using the @code{:session} header argument as well.
|
||
|
||
Unless the @code{:results output} option is supplied (see below) the result
|
||
returned is the result of the last evaluation performed by the
|
||
interpreter. (This is obtained in a language-specific manner: the value of
|
||
the variable @code{_} in Python and Ruby, and the value of @code{.Last.value}
|
||
in R).
|
||
|
||
@subsubsection @code{:results output}
|
||
The code is passed to the interpreter running as an interactive Emacs
|
||
inferior process. The result returned is the concatenation of the sequence of
|
||
(text) output from the interactive interpreter. Notice that this is not
|
||
necessarily the same as what would be sent to @code{STDOUT} if the same code
|
||
were passed to a non-interactive interpreter running as an external
|
||
process. For example, compare the following two blocks:
|
||
|
||
@example
|
||
#+BEGIN_SRC python :results output
|
||
print "hello"
|
||
2
|
||
print "bye"
|
||
#+END_SRC
|
||
|
||
#+results:
|
||
: hello
|
||
: bye
|
||
@end example
|
||
|
||
In non-session mode, the `2' is not printed and does not appear.
|
||
@example
|
||
#+BEGIN_SRC python :results output :session
|
||
print "hello"
|
||
2
|
||
print "bye"
|
||
#+END_SRC
|
||
|
||
#+results:
|
||
: hello
|
||
: 2
|
||
: bye
|
||
@end example
|
||
|
||
But in @code{:session} mode, the interactive interpreter receives input `2'
|
||
and prints out its value, `2'. (Indeed, the other print statements are
|
||
unnecessary here).

@cindex source code, noweb reference
|
||
|
||
The ``noweb'' (see @uref{http://www.cs.tufts.edu/~nr/noweb/}) Literate
|
||
Programming system allows named blocks of code to be referenced by using the
|
||
familiar Noweb syntax:
|
||
|
||
@example
|
||
<<code-block-name>>
|
||
@end example
|
||
|
||
When a code block is tangled or evaluated, whether or not ``noweb''
|
||
references are expanded depends upon the value of the @code{:noweb} header
|
||
argument. If @code{:noweb yes}, then a Noweb reference is expanded before
|
||
evaluation. If @code{:noweb no}, the default, then the reference is not
|
||
expanded before evaluation. See the @ref{noweb-ref} header argument for
|
||
a more flexible way to resolve noweb references.
|
||
|
||
It is possible to include the @emph{results} of a code block rather than the
|
||
body. This is done by appending parenthesis to the code block name which may
|
||
optionally contain arguments to the code block as shown below.
|
||
|
||
@example
|
||
<<code-block-name(optional arguments)>>
|
||
@end example
|
||
|
||
Note: the default value, @code{:noweb no}, was chosen to ensure that
|
||
correct code is not broken in a language, such as Ruby, where
|
||
@code{<<arg>>} is a syntactically valid construct. If @code{<<arg>>} is not
|
||
syntactically valid in languages that you use, then please consider setting
|
||
the default value.
|
||
|
||
Note: if noweb tangling is slow in large Org-mode files consider setting the
|
||
@code{*org-babel-use-quick-and-dirty-noweb-expansion*} variable to true.
|
||
This will result in faster noweb reference resolution at the expense of not
|
||
correctly resolving inherited values of the @code{:noweb-ref} header
|
||

@cindex insertion, of templates
|
||
|
||
Org mode supports insertion of empty structural elements (like
|
||
@code{#+BEGIN_SRC} and @code{#+END_SRC} pairs) with just a few key
|
||
strokes. This is achieved through a native template expansion mechanism.
|
||
Note that Emacs has several other template mechanisms which could be used in
|
||
a similar way, for example @file{yasnippet}.
|
||
|
||
To insert a structural element, type a @samp{<}, followed by a template
|
||
selector and @kbd{@key{TAB}}. Completion takes effect only when the above
|
||
keystrokes are typed on a line by itself.
|
||
|
||
The following template selectors are currently supported.

|
||
@section Code evaluation and security issues
|
||
|
||
Org provides tools to work with the code snippets, including evaluating them.
|
||
|
||
Running code on your machine always comes with a security risk. Badly
|
||
written or malicious code can be executed on purpose or by accident. Org has
|
||
default settings which will only evaluate such code if you give explicit
|
||
permission to do so, and as a casual user of these features you should leave
|
||
these precautions intact.
|
||
|
||
For people who regularly work with such code, the confirmation prompts can
|
||
become annoying, and you might want to turn them off. This can be done, but
|
||
you must be aware of the risks that are involved.
|
||
|
||
Code evaluation can happen under the following circumstances:
|
||
|
||
@table @i
|
||
@item Source code blocks
|
||
Source code blocks can be evaluated during export, or when pressing @kbd{C-c
|
||
C-c} in the block. The most important thing to realize here is that Org mode
|
||
files which contain code snippets are, in a certain sense, like executable
|
||
files. So you should accept them and load them into Emacs only from trusted
|
||
sources---just like you would do with a program you install on your computer.
|
||
|
||
Make sure you know what you are doing before customizing the variables
|
||
which take off the default security brakes.
|
||
|
||
@defopt org-confirm-babel-evaluate
|
||
When t (the default), the user is asked before every code block evaluation.
|
||
When nil, the user is not asked. When set to a function, it is called with
|
||
two arguments (language and body of the code block) and should return t to
|
||
ask and nil not to ask.
|
||
@end defopt
|
||
|
||
For example, here is how to execute "ditaa" code (which is considered safe)
|
||
without asking:
|
||
@example
|
||
(defun my-org-confirm-babel-evaluate (lang body)
|
||
(not (string= lang "ditaa"))) ; don't ask for ditaa
|
||
(setq org-confirm-babel-evaluate 'my-org-confirm-babel-evaluate)
|
||
@end example
|
||
|
||
@item Following @code{shell} and @code{elisp} links
|
||
Org has two link types that can directly evaluate code (@pxref{External
|
||
links}). These links can be problematic because the code to be evaluated is
|
||
not visible.
|
||
|
||
@defopt org-confirm-shell-link-function
|
||
Function to queries user about shell link execution.
|
||
@end defopt
|
||
@defopt org-confirm-elisp-link-function
|
||
Functions to query user for Emacs Lisp link execution.
|
||
@end defopt
|
||
|
||
@item Formulas in tables
|
||
Formulas in tables (@pxref{The spreadsheet}) are code that is evaluated

either by the @i{calc} interpreter, or by the @i{Emacs Lisp} interpreter.

@cindex in-buffer settings
|
||
@cindex special keywords
|
||
|
||
Org mode uses special lines in the buffer to define settings on a
|
||
per-file basis. These lines start with a @samp{#+} followed by a
|
||
keyword, a colon, and then individual words defining a setting. Several
|
||
setting words can be in the same line, but you can also have multiple
|
||
lines for the keyword. While these settings are described throughout
|
||
the manual, here is a summary. After changing any of those lines in the
|
||
buffer, press @kbd{C-c C-c} with the cursor still in the line to
|
||
activate the changes immediately. Otherwise they become effective only
|
||
when the file is visited again in a new Emacs session.
|
||
|
||
@vindex org-archive-location

||
all subsequent lines until the next @samp{#+ARCHIVE} line, or the end
|
||
of the file. The first such line also applies to any entries before it.
|
||
The corresponding variable is @code{org-archive-location}.
|
||
@item #+CATEGORY:
|
||
This line sets the category for the agenda file. The category applies
|
||
for all subsequent lines until the next @samp{#+CATEGORY} line, or the
|
||
end of the file. The first such line also applies to any entries before it.
|
||
@item #+COLUMNS: %25ITEM .....

applies.
|
||
@item #+CONSTANTS: name1=value1 ...

||
@vindex org-table-formula-constants
|

@vindex org-table-formula
|

|
||
The global version of this variable is
|
||

@item #+PRIORITIES: highest lowest default
|
||
@vindex org-highest-priority
|
||
@vindex org-lowest-priority
|
||
@vindex org-default-priority
|
||
This line sets the limits and the default for the priorities. All three
|
||
must be either letters A-Z or numbers 0-9. The highest priority must
|
||
have a lower ASCII number than the lowest priority.
|
||
@item #+PROPERTY: Property_Name Value
|
||
This line sets a default inheritance value for entries in the current
|
||
buffer, most useful for specifying the allowed values of a property.
|
||
@cindex #+SETUPFILE
|
||
@item #+SETUPFILE: file
|
||
This line defines a file that holds more in-buffer setup. Normally this is
|
||
entirely ignored. Only when the buffer is parsed for option-setting lines
|
||
(i.e.@: when starting Org mode for a file, when pressing @kbd{C-c C-c} in a
|
||
settings line, or when exporting), then the contents of this file are parsed
|
||
as if they had been included in the buffer. In particular, the file can be
|
||
any other Org mode file with internal setup. You can visit the file the
|
||
cursor is in the line with @kbd{C-c '}.
|
||
@item #+STARTUP:
|
||
@cindex #+STARTUP:
|
||
This line sets options to be used at startup of Org mode, when an
|
||
Org file is being visited.
|
||
|
||
The first set of options deals with the initial visibility of the outline
|
||
tree. The corresponding variable for global default settings is
|
||
@code{org-startup-folded}, with a default value @code{t}, which means
|
||
@code{overview}.

@cindex C-c C-c, overview
|
||
|
||
The key @kbd{C-c C-c} has many purposes in Org, which are all
|
||
mentioned scattered throughout this manual. One specific function of
|
||
this key is to add @emph{tags} to a headline (@pxref{Tags}). In many
|
||
other circumstances it means something like @emph{``Hey Org, look
|
||
here and update according to what you see here''}. Here is a summary of
|
||
what this means in different contexts.
|
||
|
||
@itemize @minus
|
||
@item
|
||
If there are highlights in the buffer from the creation of a sparse
|
||
tree, or from clock display, remove these highlights.
|
||
@item
|
||
If the cursor is in one of the special @code{#+KEYWORD} lines, this
|
||
triggers scanning the buffer for these lines and updating the
|
||
information.
|
||
@item
|
||
If the cursor is inside a table, realign the table. This command
|
||
works even if the automatic table editor has been turned off.
|
||
@item
|
||
If the cursor is on a @code{#+TBLFM} line, re-apply the formulas to
|
||
the entire table.
|
||
@item
|
||
If the current buffer is a capture buffer, close the note and file it.
|
||
With a prefix argument, file it, without further interaction, to the
|
||
default location.
|
||
@item
|
||
If the cursor is on a @code{<<<target>>>}, update radio targets and
|
||
corresponding links in this buffer.
|
||
@item
|
||
If the cursor is in a property line or at the start or end of a property
|
||
drawer, offer property commands.
|
||
@item
|
||
If the cursor is at a footnote reference, go to the corresponding
|
||
definition, and vice versa.
|
||
@item
|
||
If the cursor is on a statistics cookie, update it.
|
||
@item
|
||
If the cursor is in a plain list item with a checkbox, toggle the status
|
||
of the checkbox.
|
||
@item
|
||
If the cursor is on a numbered item in a plain list, renumber the
|
||
ordered list.
|
||
@item
|
||
If the cursor is on the @code{#+BEGIN} line of a dynamic block, the
|
||
block is updated.
|

|

|

Some people find it noisy and distracting that the Org headlines start with a
|
||
potentially large number of stars, and that text below the headlines is not
|
||
indented. While this is no problem when writing a @emph{book-like} document
|
||
where the outline headings are really section headings, in a more
|
||
@emph{list-oriented} outline, indented structure is a lot cleaner:
|
||
|
||
@example
|
||
@group
|
||
* Top level headline | * Top level headline
|
||
** Second level | * Second level
|
||
*** 3rd level | * 3rd level
|
||
some text | some text
|
||
*** 3rd level | * 3rd level
|
||
more text | more text
|
||
* Another top level headline | * Another top level headline
|
||
@end group
|
||
@end example
|
||
|
||
@noindent
|
||
|
||
If you are using at least Emacs 23.2@footnote{Emacs 23.1 can actually crash
|
||
with @code{org-indent-mode}} and version 6.29 of Org, this kind of view can
|
||
be achieved dynamically at display time using @code{org-indent-mode}. In
|
||
this minor mode, all lines are prefixed for display with the necessary amount
|
||
of space@footnote{@code{org-indent-mode} also sets the @code{wrap-prefix}
|
||
property, such that @code{visual-line-mode} (or purely setting
|
||
@code{word-wrap}) wraps long lines (including headlines) correctly indented.
|
||
}. Also headlines are prefixed with additional stars, so that the amount of
|
||
indentation shifts by two@footnote{See the variable
|
||
@code{org-indent-indentation-per-level}.} spaces per level. All headline
|
||
stars but the last one are made invisible using the @code{org-hide}
|
||
face@footnote{Turning on @code{org-indent-mode} sets
|
||
@code{org-hide-leading-stars} to @code{t} and @code{org-adapt-indentation} to
|
||
@code{nil}.} - see below under @samp{2.} for more information on how this
|
||
works. You can turn on @code{org-indent-mode} for all files by customizing
|
||
the variable @code{org-startup-indented}, or you can turn it on for
|
||
individual files using
|
||
|
||
@example
|
||
#+STARTUP: indent
|
||
@end example
|
||
|
||
If you want a similar effect in an earlier version of Emacs and/or Org, or if
|
||
you want the indentation to be hard space characters so that the plain text
|
||
file looks as similar as possible to the Emacs display, Org supports you in
|
||
the following way:
|
||
|
||
@enumerate
|
||
@item
|
||
@emph{Indentation of text below headlines}@*
|
||
You may indent text below each headline to make the left boundary line up
|
||
with the headline, like
|
||
|
||
@example
|
||
*** 3rd level
|
||
more text, now indented
|
||
@end example
|
||
|
||
@vindex org-adapt-indentation
|
||
Org supports this with paragraph filling, line wrapping, and structure
|
||
editing@footnote{See also the variable @code{org-adapt-indentation}.},
|
||
preserving or adapting the indentation as appropriate.
|
||
|
||
@item
|
||
@vindex org-hide-leading-stars
|
||
@emph{Hiding leading stars}@* You can modify the display in such a way that
|
||
all leading stars become invisible. To do this in a global way, configure
|
||
the variable @code{org-hide-leading-stars} or change this on a per-file basis
|
||
with
|
||
|
||
@example
|
||
#+STARTUP: hidestars
|
||
#+STARTUP: showstars
|
||
@end example
|
||
|
||
With hidden stars, the tree becomes:
|
||
|
||
@example
|
||
@group
|
||
* Top level headline
|
||
* Second level
|
||
* 3rd level
|
||
...
|
||
@end group
|
||
@end example
|
||
|
||
@noindent
|
||
@vindex org-hide @r{(face)}
|
||
The leading stars are not truly replaced by whitespace, they are only
|
||
fontified with the face @code{org-hide} that uses the background color as
|
||
font color. If you are not using either white or black background, you may
|
||
have to customize this face to get the wanted effect. Another possibility is
|
||
to set this font such that the extra stars are @i{almost} invisible, for
|
||
example using the color @code{grey90} on a white background.
|
||
|
||
@item
|
||
@vindex org-odd-levels-only
|
||
Things become cleaner still if you skip all the even levels and use only odd
|
||
levels 1, 3, 5..., effectively adding two stars to go from one outline level
|
||
to the next@footnote{When you need to specify a level for a property search
|
||
or refile targets, @samp{LEVEL=2} will correspond to 3 stars, etc@.}. In this
|
||
way we get the outline view shown at the beginning of this section. In order
|
||
to make the structure editing and export commands handle this convention
|
||
correctly, configure the variable @code{org-odd-levels-only}, or set this on
|
||
a per-file basis with one of the following lines:
|
||
|
||
@example
|
||
#+STARTUP: odd
|
||
#+STARTUP: oddeven
|
||
@end example
|
||
|
||
You can convert an Org file from single-star-per-level to the
|
||
double-star-per-level convention with @kbd{M-x org-convert-to-odd-levels
|
||
RET} in that file. The reverse operation is @kbd{M-x
|
||
org-convert-to-oddeven-levels}.

@section Using Org on a tty

@cindex tty key bindings
|
||
|
||
Because Org contains a large number of commands, by default many of
|
||
Org's core commands are bound to keys that are generally not
|
||
accessible on a tty, such as the cursor keys (@key{left}, @key{right},
|
||
@key{up}, @key{down}), @key{TAB} and @key{RET}, in particular when used
|
||
together with modifiers like @key{Meta} and/or @key{Shift}. To access
|
||
these commands on a tty when special keys are unavailable, the following
|
||
alternative bindings can be used. The tty bindings below will likely be
|
||
more cumbersome; you may find for some of the bindings below that a
|
||
customized workaround suits you better. For example, changing a timestamp
|
||
is really only fun with @kbd{S-@key{cursor}} keys, whereas on a
|
||
tty you would rather use @kbd{C-c .} to re-insert the timestamp.

@item @file{calc.el} by Dave Gillespie
|
||
Org uses the Calc package for implementing spreadsheet
|
||
functionality in its tables (@pxref{The spreadsheet}). Org
|
||
checks for the availability of Calc by looking for the function
|
||
@code{calc-eval} which will have been autoloaded during setup if Calc has
|
||
been installed properly. As of Emacs 22, Calc is part of the Emacs
|
||
distribution. Another possibility for interaction between the two
|
||
packages is using Calc for embedded calculations. @xref{Embedded Mode,
|
||
, Embedded Mode, calc, GNU Emacs Calc Manual}.

@cindex @file{constants.el}

@cindex Dominik, Carsten
|
||
@vindex org-table-formula-constants
|
||
In a table formula (@pxref{The spreadsheet}), it is possible to use
|
||
names for natural constants or units. Instead of defining your own
|
||
constants in the variable @code{org-table-formula-constants}, install
|
||
the @file{constants} package which defines a large number of constants
|
||
and units, and lets you use unit prefixes like @samp{M} for
|
||
@samp{Mega}, etc@. You will need version 2.0 of this package, available
|
||
at @url{http://www.astro.uva.nl/~dominik/Tools}. Org checks for
|
||
the function @code{constants-get}, which has to be autoloaded in your
|
||
setup. See the installation instructions in the file
|
||
@file{constants.el}.
|
||
@item @file{cdlatex.el} by Carsten Dominik

Org mode can make use of the CD@LaTeX{} package to efficiently enter
|

@LaTeX{} fragments into Org files. See @ref{CDLaTeX mode}.
|
||
@item @file{imenu.el} by Ake Stenhoff and Lars Lindberg
|
||
@cindex @file{imenu.el}
|
||
Imenu allows menu access to an index of items in a file. Org mode
|
||
supports Imenu---all you need to do to get the index is the following:
|
||
@lisp
|
||
(add-hook 'org-mode-hook
|
||
(lambda () (imenu-add-to-menubar "Imenu")))
|
||
@end lisp
|
||
@vindex org-imenu-depth
|
||
By default the index is two levels deep---you can modify the depth using
|
||
the option @code{org-imenu-depth}.

@item @file{speedbar.el} by Eric M. Ludlam
|
||
@cindex @file{speedbar.el}
|
||
@cindex Ludlam, Eric M.
|
||
Speedbar is a package that creates a special frame displaying files and
|
||
index items in files. Org mode supports Speedbar and allows you to
|
||
drill into Org files directly from the Speedbar. It also allows you to
|
||
restrict the scope of agenda commands to a file or a subtree by using
|
||
the command @kbd{<} in the Speedbar frame.

Complex ASCII tables with automatic line wrapping, column- and row-spanning,
|
||
and alignment can be created using the Emacs table package by Takaaki Ota
|
||
(@uref{http://sourceforge.net/projects/table}, and also part of Emacs 22).
|
||
Org mode will recognize these tables and export them properly. Because of
|
||
interference with other Org mode functionality, you unfortunately cannot edit
|
||
these tables directly in the buffer. Instead, you need to use the command
|
||
@kbd{C-c '} to edit them, similar to source code snippets.
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c ',org-edit-special}
|
||
Edit a @file{table.el} table. Works when the cursor is in a table.el table.
|
||
@c
|
||
@orgcmd{C-c ~,org-table-create-with-table.el}
|
||
Insert a @file{table.el} table. If there is already a table at point, this
|
||
command converts it between the @file{table.el} format and the Org mode
|
||
format. See the documentation string of the command
|
||
@code{org-convert-table} for the restrictions under which this is
|
||
possible.
|

@file{table.el} is part of Emacs since Emacs 22.

@cindex Baur, Steven L.
|

Org mode recognizes numerical footnotes as provided by this package.
|
||
However, Org mode also has its own footnote support (@pxref{Footnotes}),

which makes using @file{footnote.el} unnecessary.

@table @asis
|

|
||
@cindex @code{shift-selection-mode}
|
||
@vindex org-support-shift-select
|
||
In Emacs 23, @code{shift-selection-mode} is on by default, meaning that
|
||
cursor motions combined with the shift key should start or enlarge regions.
|
||
This conflicts with the use of @kbd{S-@key{cursor}} commands in Org to change
|
||
timestamps, TODO keywords, priorities, and item bullet types if the cursor is
|
||
at such a location. By default, @kbd{S-@key{cursor}} commands outside
|
||
special contexts don't do anything, but you can customize the variable
|
||
@code{org-support-shift-select}. Org mode then tries to accommodate shift
|
||
selection by (i) using it outside of the special contexts where special
|
||
commands apply, and by (ii) extending an existing active region even if the
|
||
cursor moves across a special context.
|
||
|
||
@item @file{CUA.el} by Kim. F. Storm
|
||
@cindex @file{CUA.el}
|
||
@cindex Storm, Kim. F.
|
||
@vindex org-replace-disputed-keys
|
||
Key bindings in Org conflict with the @kbd{S-<cursor>} keys used by CUA mode
|
||
(as well as @code{pc-select-mode} and @code{s-region-mode}) to select and extend the
|
||
region. In fact, Emacs 23 has this built-in in the form of
|
||
@code{shift-selection-mode}, see previous paragraph. If you are using Emacs
|
||
23, you probably don't want to use another package for this purpose. However,
|
||
if you prefer to leave these keys to a different package while working in
|
||
Org mode, configure the variable @code{org-replace-disputed-keys}. When set,
|
||
Org will move the following key bindings in Org files, and in the agenda
|
||
buffer (but not during date selection).
|
||
|
||
@example
|
||
S-UP @result{} M-p S-DOWN @result{} M-n
|
||
S-LEFT @result{} M-- S-RIGHT @result{} M-+
|
||
C-S-LEFT @result{} M-S-- C-S-RIGHT @result{} M-S-+
|
||
@end example
|
||
|
||
@vindex org-disputed-keys
|
||
Yes, these are unfortunately more difficult to remember. If you want
|
||
to have other replacement keys, look at the variable
|
||
@code{org-disputed-keys}.
|
||
|
||
@item @file{yasnippet.el}
|
||
@cindex @file{yasnippet.el}
|
||
The way Org mode binds the TAB key (binding to @code{[tab]} instead of
|
||
@code{"\t"}) overrules YASnippet's access to this key. The following code
|
||
fixed this problem:
|
||
|
||
@lisp
|
||
(add-hook 'org-mode-hook
|
||
(lambda ()
|
||
(org-set-local 'yas/trigger-key [tab])
|
||
(define-key yas/keymap [tab] 'yas/next-field-or-maybe-expand)))
|
||
@end lisp
|
||
|
||
The latest version of yasnippet doesn't play well with Org mode. If the
|
||
above code does not fix the conflict, start by defining the following
|
||
function:
|
||
|
||
@lisp
|
||
(defun yas/org-very-safe-expand ()
|
||
(let ((yas/fallback-behavior 'return-nil)) (yas/expand)))
|
||
@end lisp
|
||
|
||
Then, tell Org mode what to do with the new function:
|
||
|
||
@lisp
|
||
(add-hook 'org-mode-hook
|
||
(lambda ()
|
||
(make-variable-buffer-local 'yas/trigger-key)
|
||
(setq yas/trigger-key [tab])
|
||
(add-to-list 'org-tab-first-hook 'yas/org-very-safe-expand)

(define-key yas/keymap [tab] 'yas/next-field)))

@end lisp
|

|
||
@item @file{windmove.el} by Hovav Shacham
|
||
@cindex @file{windmove.el}
|
||
This package also uses the @kbd{S-<cursor>} keys, so everything written
|
||
in the paragraph above about CUA mode also applies here. If you want make
|
||
the windmove function active in locations where Org mode does not have
|
||
special functionality on @kbd{S-@key{cursor}}, add this to your
|
||
configuration:
|
||
|
||
@lisp
|
||
;; Make windmove work in org-mode:
|
||
(add-hook 'org-shiftup-final-hook 'windmove-up)
|

(add-hook 'org-shiftleft-final-hook 'windmove-left)

Viper uses @kbd{C-c /} and therefore makes this key not access the

another key for this command, or override the key in
|
||
@code{viper-vi-global-user-map} with
|
||
|

@lisp

@cindex @code{org-decrypt-entry}
|
||
|
||
Org-crypt will encrypt the text of an entry, but not the headline, or
|
||
properties. Org-crypt uses the Emacs EasyPG library to encrypt and decrypt
|
||
files.
|
||
|
||
Any text below a headline that has a @samp{:crypt:} tag will be automatically
|
||
be encrypted when the file is saved. If you want to use a different tag just
|
||
customize the @code{org-crypt-tag-matcher} setting.
|
||
|
||
To use org-crypt it is suggested that you have the following in your
|
||
@file{.emacs}:
|
||
|
||
@example
|
||
(require 'org-crypt)
|
||
(org-crypt-use-before-save-magic)
|
||
(setq org-tags-exclude-from-inheritance (quote ("crypt")))
|
||
|
||
(setq org-crypt-key nil)
|
||
;; GPG key to use for encryption
|
||
;; Either the Key ID or set to nil to use symmetric encryption.
|
||
|
||
(setq auto-save-default nil)
|
||
;; Auto-saving does not cooperate with org-crypt.el: so you need
|
||
;; to turn it off if you plan to use org-crypt.el quite often.
|
||
;; Otherwise, you'll get an (annoying) message each time you
|
||
;; start Org.
|
||
|
||
;; To turn it off only locally, you can insert this:
|
||
;;
|
||
;; # -*- buffer-auto-save-file-name: nil; -*-
|
||
@end example
|
||
|
||
Excluding the crypt tag from inheritance prevents already encrypted text
|
||
being encrypted again.

|

Org has a large number of hyperlink types built-in

||
(@pxref{Hyperlinks}). If you would like to add new link types, Org
|
||
provides an interface for doing so. Let's look at an example file,
|
||
@file{org-man.el}, that will add support for creating links like
|
||
@samp{[[man:printf][The printf manpage]]} to show Unix manual pages inside

@end lisp
|
||
|
||
@noindent
|
||
Let's go through the file and see what it does.
|
||
@enumerate
|
||
@item
|
||
It does @code{(require 'org)} to make sure that @file{org.el} has been
|
||
loaded.
|
||
@item
|
||
The next line calls @code{org-add-link-type} to define a new link type
|
||
with prefix @samp{man}. The call also contains the name of a function
|
||
that will be called to follow such a link.
|
||
@item
|
||
@vindex org-store-link-functions
|
||
The next line adds a function to @code{org-store-link-functions}, in
|
||
order to allow the command @kbd{C-c l} to record a useful link in a
|
||
buffer displaying a man page.
|
||
@end enumerate
|
||
|
||
The rest of the file defines the necessary variables and functions.
|
||
First there is a customization variable that determines which Emacs
|
||
command should be used to display man pages. There are two options,
|
||
@code{man} and @code{woman}. Then the function to follow a link is
|
||
defined. It gets the link path as an argument---in this case the link
|
||
path is just a topic for the manual command. The function calls the
|
||
value of @code{org-man-command} to display the man page.
|
||
|
||
Finally the function @code{org-man-store-link} is defined. When you try
|
||
to store a link with @kbd{C-c l}, this function will be called to
|
||
try to make a link. The function must first decide if it is supposed to
|
||
create the link for this buffer type; we do this by checking the value
|
||
of the variable @code{major-mode}. If not, the function must exit and
|
||
return the value @code{nil}. If yes, the link is created by getting the
|
||
manual topic from the buffer name and prefixing it with the string
|
||
@samp{man:}. Then it must call the command @code{org-store-link-props}
|
||
and set the @code{:type} and @code{:link} properties. Optionally you
|
||
can also set the @code{:description} property to provide a default for
|
||
the link description when the link is later inserted into an Org
|
||
buffer with @kbd{C-c C-l}.
|
||
|
||
When it makes sense for your new link type, you may also define a function
|
||
@code{org-PREFIX-complete-link} that implements special (e.g.@: completion)
|
||
support for inserting such a link with @kbd{C-c C-l}. Such a function should
|
||
not accept any arguments, and return the full link with prefix.
|
||
|

@cindex add-ons, context-sensitive commands
|
||
@vindex org-ctrl-c-ctrl-c-hook
|
||
|
||
Org has several commands that act differently depending on context. The most
|
||
important example is the @kbd{C-c C-c} (@pxref{The very busy C-c C-c key}).
|
||
Also the @kbd{M-cursor} and @kbd{M-S-cursor} keys have this property.
|
||
|
||
Add-ons can tap into this functionality by providing a function that detects
|
||
special context for that add-on and executes functionality appropriate for
|
||
the context. Here is an example from Dan Davison's @file{org-R.el} which
|
||
allows you to evaluate commands based on the @file{R} programming language
|
||
@footnote{@file{org-R.el} has been replaced by the Org mode functionality
|
||
described in @ref{Working With Source Code} and is now obsolete.}. For this
|
||
package, special contexts are lines that start with @code{#+R:} or
|
||
@code{#+RR:}.
|
||
|
||
@lisp
|
||
(defun org-R-apply-maybe ()
|
||
"Detect if this is context for org-R and execute R commands."
|
||

||
(looking-at "#\\+RR?:"))

||
nil)) ;; to signal that we did not
|
||
|
||
(add-hook 'org-ctrl-c-ctrl-c-hook 'org-R-apply-maybe)
|
||
@end lisp
|
||
|
||
The function first checks if the cursor is in such a line. If that is the
|
||
case, @code{org-R-apply} is called and the function returns @code{t} to
|
||
signal that action was taken, and @kbd{C-c C-c} will stop looking for other
|
||
contexts. If the function finds it should do nothing locally, it returns
|
||
@code{nil} so that other, similar functions can have a try.

|
||
|
||
Since Orgtbl mode can be used as a minor mode in arbitrary buffers, a
|
||
frequent feature request has been to make it work with native tables in
|
||
specific languages, for example @LaTeX{}. However, this is extremely
|
||
hard to do in a general way, would lead to a customization nightmare,
|
||
and would take away much of the simplicity of the Orgtbl mode table
|
||
editor.
|
||
|
||
This appendix describes a different approach. We keep the Orgtbl mode
|
||
table in its native format (the @i{source table}), and use a custom
|
||
function to @i{translate} the table to the correct syntax, and to
|
||
@i{install} it in the right location (the @i{target table}). This puts
|
||
the burden of writing conversion functions on the user, but it allows
|
||
for a very flexible system.
|
||
|
||
Bastien added the ability to do the same with lists, in Orgstruct mode. You
|
||
can use Org's facilities to edit and structure lists by turning
|
||
@code{orgstruct-mode} on, then locally exporting such lists in another format
|
||
(HTML, @LaTeX{} or Texinfo.)

@subsection Radio tables
|
||
@cindex radio tables
|
||
|
||
To define the location of the target table, you first need to create two
|
||
lines that are comments in the current mode, but contain magic words for
|
||
Orgtbl mode to find. Orgtbl mode will insert the translated table
|
||
between these lines, replacing whatever was there before. For example:
|
||
|
||
@example
|
||
/* BEGIN RECEIVE ORGTBL table_name */
|
||
/* END RECEIVE ORGTBL table_name */
|
||
@end example
|
||
|
||
@noindent
|
||
Just above the source table, we put a special line that tells
|
||
Orgtbl mode how to translate this table and where to install it. For
|
||
example:
|
||
@cindex #+ORGTBL
|
||
@example
|
||
#+ORGTBL: SEND table_name translation_function arguments....
|
||
@end example
|
||
|
||
@noindent
|
||
@code{table_name} is the reference name for the table that is also used
|
||
in the receiver lines. @code{translation_function} is the Lisp function
|
||
that does the translation. Furthermore, the line can contain a list of
|
||
arguments (alternating key and value) at the end. The arguments will be
|
||
passed as a property list to the translation function for
|
||
interpretation. A few standard parameters are already recognized and
|
||
acted upon before the translation function is called:
|
||
|
||
@table @code
|
||
@item :skip N
|
||
Skip the first N lines of the table. Hlines do count as separate lines for
|
||
this parameter!
|
||
|
||
@item :skipcols (n1 n2 ...)
|
||
List of columns that should be skipped. If the table has a column with
|
||
calculation marks, that column is automatically discarded as well.
|
||
Please note that the translator function sees the table @emph{after} the
|
||
removal of these columns, the function never knows that there have been
|
||
additional columns.
|
||
@end table
|
||
|
||
@noindent
|
||
The one problem remaining is how to keep the source table in the buffer
|
||
without disturbing the normal workings of the file, for example during
|
||
compilation of a C file or processing of a @LaTeX{} file. There are a
|
||
number of different solutions:
|
||
|
||
@itemize @bullet
|
||
@item
|
||
The table could be placed in a block comment if that is supported by the
|
||
language. For example, in C mode you could wrap the table between
|
||
@samp{/*} and @samp{*/} lines.
|
||
@item
|
||
Sometimes it is possible to put the table after some kind of @i{END}
|
||
statement, for example @samp{\bye} in @TeX{} and @samp{\end@{document@}}
|
||
in @LaTeX{}.
|
||
@item
|
||
You can just comment the table line-by-line whenever you want to process
|
||
the file, and uncomment it whenever you need to edit the table. This
|
||
only sounds tedious---the command @kbd{M-x orgtbl-toggle-comment}
|
||
makes this comment-toggling very easy, in particular if you bind it to a
|
||
key.

@subsection A @LaTeX{} example of radio tables
|
||
@cindex @LaTeX{}, and Orgtbl mode
|
||
|
||
The best way to wrap the source table in @LaTeX{} is to use the
|
||
@code{comment} environment provided by @file{comment.sty}. It has to be
|
||
activated by placing @code{\usepackage@{comment@}} into the document
|
||
header. Orgtbl mode can insert a radio table skeleton@footnote{By
|
||
default this works only for @LaTeX{}, HTML, and Texinfo. Configure the
|
||
variable @code{orgtbl-radio-tables} to install templates for other
|
||
modes.} with the command @kbd{M-x orgtbl-insert-radio-table}. You will
|
||
be prompted for a table name, let's say we use @samp{salesfigures}. You
|
||
will then get the following template:
|
||
|
||
@cindex #+ORGTBL, SEND
|
||
@example
|
||
% BEGIN RECEIVE ORGTBL salesfigures
|
||
% END RECEIVE ORGTBL salesfigures
|
||
\begin@{comment@}
|
||
#+ORGTBL: SEND salesfigures orgtbl-to-latex
|
||
| | |
|
||
\end@{comment@}
|
||
@end example
|
||
|
||
@noindent
|
||
@vindex @LaTeX{}-verbatim-environments
|
||
The @code{#+ORGTBL: SEND} line tells Orgtbl mode to use the function
|
||
@code{orgtbl-to-latex} to convert the table into @LaTeX{} and to put it
|
||
into the receiver location with name @code{salesfigures}. You may now
|
||
fill in the table---feel free to use the spreadsheet features@footnote{If
|
||
the @samp{#+TBLFM} line contains an odd number of dollar characters,
|
||
this may cause problems with font-lock in @LaTeX{} mode. As shown in the
|
||
example you can fix this by adding an extra line inside the
|
||
@code{comment} environment that is used to balance the dollar
|
||
expressions. If you are using AUC@TeX{} with the font-latex library, a
|
||
much better solution is to add the @code{comment} environment to the
|
||
variable @code{LaTeX-verbatim-environments}.}:
|
||
|
||
@example
|
||
% BEGIN RECEIVE ORGTBL salesfigures
|
||
% END RECEIVE ORGTBL salesfigures

@noindent
|

When you are done, press @kbd{C-c C-c} in the table to get the converted

table inserted between the two marker lines.
|
||
|
||
Now let's assume you want to make the table header by hand, because you
|
||
want to control how columns are aligned, etc@. In this case we make sure
|
||
that the table translator skips the first 2 lines of the source
|
||
table, and tell the command to work as a @i{splice}, i.e.@: to not produce
|
||
header and footer commands of the target table:
|
||
|
||
@example
|
||
\begin@{tabular@}@{lrrr@}

\end@{comment@}
|
||
@end example
|
||
|
||
The @LaTeX{} translator function @code{orgtbl-to-latex} is already part of
|
||
Orgtbl mode. It uses a @code{tabular} environment to typeset the table
|
||
and marks horizontal lines with @code{\hline}. Furthermore, it
|
||
interprets the following parameters (see also @pxref{Translator functions}):
|
||
|
||
@table @code
|
||
@item :splice nil/t
|
||
When set to t, return only table body lines, don't wrap them into a
|
||
tabular environment. Default is nil.
|
||
|
||
@item :fmt fmt
|
||
A format to be used to wrap each field, it should contain @code{%s} for the
|
||
original field value. For example, to wrap each field value in dollars,
|
||
you could use @code{:fmt "$%s$"}. This may also be a property list with
|
||
column numbers and formats, for example @code{:fmt (2 "$%s$" 4 "%s\\%%")}.
|
||
A function of one argument can be used in place of the strings; the
|
||
function must return a formatted string.
|
||
|
||
@item :efmt efmt
|
||
Use this format to print numbers with exponentials. The format should
|
||
have @code{%s} twice for inserting mantissa and exponent, for example
|
||
@code{"%s\\times10^@{%s@}"}. The default is @code{"%s\\,(%s)"}. This
|
||
may also be a property list with column numbers and formats, for example
|
||
@code{:efmt (2 "$%s\\times10^@{%s@}$" 4 "$%s\\cdot10^@{%s@}$")}. After
|
||
@code{efmt} has been applied to a value, @code{fmt} will also be
|
||
applied. Similar to @code{fmt}, functions of two arguments can be
|
||
supplied instead of strings.

@subsection Translator functions
|
||
@cindex HTML, and Orgtbl mode
|
||
@cindex translator function
|
||
|
||
Orgtbl mode has several translator functions built-in: @code{orgtbl-to-csv}
|
||
(comma-separated values), @code{orgtbl-to-tsv} (TAB-separated values)
|
||
@code{orgtbl-to-latex}, @code{orgtbl-to-html}, and @code{orgtbl-to-texinfo}.
|
||
Except for @code{orgtbl-to-html}@footnote{The HTML translator uses the same
|
||
code that produces tables during HTML export.}, these all use a generic
|
||
translator, @code{orgtbl-to-generic}. For example, @code{orgtbl-to-latex}
|
||
itself is a very short function that computes the column definitions for the
|
||
@code{tabular} environment, defines a few field and line separators and then
|
||
hands processing over to the generic translator. Here is the entire code:
|
||
|
||
@lisp
|
||
@group
|
||
(defun orgtbl-to-latex (table params)
|
||
"Convert the Orgtbl mode TABLE to LaTeX."
|
||
(let* ((alignment (mapconcat (lambda (x) (if x "r" "l"))
|
||
org-table-last-alignment ""))
|
||
(params2
|
||
(list
|
||
:tstart (concat "\\begin@{tabular@}@{" alignment "@}")
|
||
:tend "\\end@{tabular@}"
|
||
:lstart "" :lend " \\\\" :sep " & "
|
||
:efmt "%s\\,(%s)" :hline "\\hline")))
|
||
(orgtbl-to-generic table (org-combine-plists params2 params))))
|
||
@end group
|
||
@end lisp
|
||
|
||
As you can see, the properties passed into the function (variable
|
||
@var{PARAMS}) are combined with the ones newly defined in the function
|
||
(variable @var{PARAMS2}). The ones passed into the function (i.e.@: the
|
||
ones set by the @samp{ORGTBL SEND} line) take precedence. So if you
|
||
would like to use the @LaTeX{} translator, but wanted the line endings to
|
||
be @samp{\\[2mm]} instead of the default @samp{\\}, you could just
|
||
overrule the default with
|
||
|
||
@example
|
||
#+ORGTBL: SEND test orgtbl-to-latex :lend " \\\\[2mm]"
|
||
@end example
|
||
|
||
For a new language, you can either write your own converter function in
|
||
analogy with the @LaTeX{} translator, or you can use the generic function
|
||
directly. For example, if you have a language where a table is started
|
||
with @samp{!BTBL!}, ended with @samp{!ETBL!}, and where table lines are
|
||
started with @samp{!BL!}, ended with @samp{!EL!}, and where the field
|
||
separator is a TAB, you could call the generic translator like this (on
|
||
a single line!):
|
||
|
||
@example
|
||
#+ORGTBL: SEND test orgtbl-to-generic :tstart "!BTBL!" :tend "!ETBL!"
|
||
:lstart "!BL! " :lend " !EL!" :sep "\t"
|
||
@end example
|
||
|
||
@noindent
|
||
Please check the documentation string of the function
|
||
@code{orgtbl-to-generic} for a full list of parameters understood by
|
||
that function, and remember that you can pass each of them into
|
||
@code{orgtbl-to-latex}, @code{orgtbl-to-texinfo}, and any other function
|
||
using the generic function.
|
||
|
||
Of course you can also write a completely new function doing complicated
|
||
things the generic translator cannot do. A translator function takes
|
||
two arguments. The first argument is the table, a list of lines, each
|
||
line either the symbol @code{hline} or a list of fields. The second
|
||
argument is the property list containing all parameters specified in the
|
||
@samp{#+ORGTBL: SEND} line. The function must return a single string
|
||
containing the formatted table. If you write a generally useful
|
||
translator, please post it on @email{emacs-orgmode@@gnu.org} so that
|
||
others can benefit from your work.

@node Dynamic blocks, Special agenda views, Tables in arbitrary syntax, Hacking

@section Dynamic blocks
|
||
@cindex dynamic blocks
|
||
|
||
Org documents can contain @emph{dynamic blocks}. These are
|
||
specially marked regions that are updated by some user-written function.
|
||
A good example for such a block is the clock table inserted by the
|
||
command @kbd{C-c C-x C-r} (@pxref{Clocking work time}).
|
||
|
||
Dynamic blocks are enclosed by a BEGIN-END structure that assigns a name
|
||
to the block and can also specify parameters for the function producing
|
||
the content of the block.
|
||
|
||
@cindex #+BEGIN:dynamic block
|
||
@example
|
||
#+BEGIN: myblock :parameter1 value1 :parameter2 value2 ...
|
||
|
||
#+END:
|
||
@end example
|
||
|
||
Dynamic blocks are updated with the following commands
|
||
|
||
@table @kbd
|
||
@orgcmd{C-c C-x C-u,org-dblock-update}
|
||
Update dynamic block at point.
|
||
@orgkey{C-u C-c C-x C-u}
|
||
Update all dynamic blocks in the current file.
|
||
@end table
|
||
|
||
Updating a dynamic block means to remove all the text between BEGIN and
|
||
END, parse the BEGIN line for parameters and then call the specific
|
||
writer function for this block to insert the new content. If you want
|
||
to use the original content in the writer function, you can use the
|
||
extra parameter @code{:content}.
|
||
|
||
For a block with name @code{myblock}, the writer function is
|
||
@code{org-dblock-write:myblock} with as only parameter a property list
|
||
with the parameters given in the begin line. Here is a trivial example
|
||
of a block that keeps track of when the block update function was last
|
||
run:
|
||
|
||
@example
|
||
#+BEGIN: block-update-time :format "on %m/%d/%Y at %H:%M"
|
||
|
||
#+END:
|
||
@end example
|
||
|
||
@noindent
|
||
The corresponding block writer function could look like this:
|
||
|
||
@lisp
|
||
(defun org-dblock-write:block-update-time (params)
|
||
(let ((fmt (or (plist-get params :format) "%d. %m. %Y")))
|
||
(insert "Last block update at: "
|
||
(format-time-string fmt (current-time)))))
|
||
@end lisp
|
||
|
||
If you want to make sure that all dynamic blocks are always up-to-date,
|
||
you could add the function @code{org-update-all-dblocks} to a hook, for
|
||
example @code{before-save-hook}. @code{org-update-all-dblocks} is
|
||
written in a way such that it does nothing in buffers that are not in
|
||
@code{org-mode}.
|
||
|
||
You can narrow the current buffer to the current dynamic block (like any
|
||
other block) with @code{org-narrow-to-block}.

@node Special agenda views, Extracting agenda information, Dynamic blocks, Hacking

@cindex agenda views, user-defined
|

|
||
@vindex org-agenda-skip-function
|
||
@vindex org-agenda-skip-function-global
|
||
Org provides a special hook that can be used to narrow down the selection
|
||
made by these agenda views: @code{agenda}, @code{todo}, @code{alltodo},
|
||
@code{tags}, @code{tags-todo}, @code{tags-tree}. You may specify a function
|
||
that is used at each match to verify if the match should indeed be part of
|
||
the agenda view, and if not, how much should be skipped. You can specify a
|
||
global condition that will be applied to all agenda views, this condition
|
||
would be stored in the variable @code{org-agenda-skip-function-global}. More
|
||
commonly, such a definition is applied only to specific custom searches,
|
||
using @code{org-agenda-skip-function}.
|
||
|
||
Let's say you want to produce a list of projects that contain a WAITING
|
||
tag anywhere in the project tree. Let's further assume that you have
|
||
marked all tree headings that define a project with the TODO keyword
|
||
PROJECT. In this case you would run a TODO search for the keyword
|
||
PROJECT, but skip the match unless there is a WAITING tag anywhere in
|
||
the subtree belonging to the project line.
|
||
|
||
To achieve this, you must write a function that searches the subtree for
|
||
the tag. If the tag is found, the function must return @code{nil} to
|
||
indicate that this match should not be skipped. If there is no such
|
||
tag, return the location of the end of the subtree, to indicate that
|
||
search should continue from there.
|
||
|
||
@lisp
|
||
(defun my-skip-unless-waiting ()
|
||
"Skip trees that are not waiting"
|
||
(let ((subtree-end (save-excursion (org-end-of-subtree t))))
|
||
(if (re-search-forward ":waiting:" subtree-end t)
|
||
nil ; tag found, do not skip
|
||
subtree-end))) ; tag not found, continue after end of subtree
|
||
@end lisp
|
||
|
||
Now you may use this function in an agenda custom command, for example
|
||
like this:
|
||
|
||
@lisp
|
||
(org-add-agenda-custom-command
|
||
'("b" todo "PROJECT"
|
||
((org-agenda-skip-function 'my-skip-unless-waiting)
|
||
(org-agenda-overriding-header "Projects waiting for something: "))))
|
||
@end lisp
|
||
|
||
@vindex org-agenda-overriding-header
|
||
Note that this also binds @code{org-agenda-overriding-header} to get a
|
||
meaningful header in the agenda view.
|
||
|
||
@vindex org-odd-levels-only
|
||
@vindex org-agenda-skip-function
|
||
A general way to create custom searches is to base them on a search for
|
||
entries with a certain level limit. If you want to study all entries with
|
||
your custom search function, simply do a search for
|
||
@samp{LEVEL>0}@footnote{Note that, when using @code{org-odd-levels-only}, a
|
||
level number corresponds to order in the hierarchy, not to the number of
|
||
stars.}, and then use @code{org-agenda-skip-function} to select the entries
|
||
you really want to have.
|
||
|
||
You may also put a Lisp form into @code{org-agenda-skip-function}. In
|
||
particular, you may use the functions @code{org-agenda-skip-entry-if}
|
||
and @code{org-agenda-skip-subtree-if} in this form, for example:
|
||
|
||
@table @code
|
||
@item (org-agenda-skip-entry-if 'scheduled)
|
||
Skip current entry if it has been scheduled.
|
||
@item (org-agenda-skip-entry-if 'notscheduled)
|
||
Skip current entry if it has not been scheduled.
|
||
@item (org-agenda-skip-entry-if 'deadline)
|
||
Skip current entry if it has a deadline.
|
||
@item (org-agenda-skip-entry-if 'scheduled 'deadline)
|
||
Skip current entry if it has a deadline, or if it is scheduled.
|
||
@item (org-agenda-skip-entry-if 'todo '("TODO" "WAITING"))
|
||
Skip current entry if the TODO keyword is TODO or WAITING.
|
||
@item (org-agenda-skip-entry-if 'todo 'done)
|
||
Skip current entry if the TODO keyword marks a DONE state.
|
||
@item (org-agenda-skip-entry-if 'timestamp)
|
||
Skip current entry if it has any timestamp, may also be deadline or scheduled.
|
||
@item (org-agenda-skip-entry 'regexp "regular expression")
|
||
Skip current entry if the regular expression matches in the entry.
|
||
@item (org-agenda-skip-entry 'notregexp "regular expression")
|
||
Skip current entry unless the regular expression matches.
|
||
@item (org-agenda-skip-subtree-if 'regexp "regular expression")
|

@cindex agenda, pipe

@cindex Scripts, for agenda processing
|
||
|
||
@vindex org-agenda-custom-commands
|
||
Org provides commands to access agenda information for the command
|
||
line in Emacs batch mode. This extracted information can be sent
|
||
directly to a printer, or it can be read by a program that does further
|
||
processing of the data. The first of these commands is the function
|
||
@code{org-batch-agenda}, that produces an agenda view and sends it as
|
||
ASCII text to STDOUT. The command takes a single string as parameter.
|
||
If the string has length 1, it is used as a key to one of the commands
|
||
you have configured in @code{org-agenda-custom-commands}, basically any
|
||
key you can use after @kbd{C-c a}. For example, to directly print the
|
||
current TODO list, you could use
|
||
|
||
@example
|
||
emacs -batch -l ~/.emacs -eval '(org-batch-agenda "t")' | lpr
|
||
@end example
|
||
|
||
If the parameter is a string with 2 or more characters, it is used as a
|
||
tags/TODO match string. For example, to print your local shopping list
|
||
(all items with the tag @samp{shop}, but excluding the tag
|
||
@samp{NewYork}), you could use
|
||
|
||
@example
|
||
emacs -batch -l ~/.emacs \
|
||
-eval '(org-batch-agenda "+shop-NewYork")' | lpr
|
||
@end example
|
||
|
||
@noindent
|
||
You may also modify parameters on the fly like this:
|
||
|
||
@example
|
||
emacs -batch -l ~/.emacs \
|
||
-eval '(org-batch-agenda "a" \
|
||
org-agenda-span (quote month) \
|
||
org-agenda-include-diary nil \
|
||
org-agenda-files (quote ("~/org/project.org")))' \
|
||
| lpr
|
||
@end example
|
||
|
||
@noindent
|
||
which will produce a 30-day agenda, fully restricted to the Org file
|
||
@file{~/org/projects.org}, not even including the diary.
|
||
|
||
If you want to process the agenda data in more sophisticated ways, you
|
||
can use the command @code{org-batch-agenda-csv} to get a comma-separated
|
||
list of values for each agenda item. Each line in the output will
|
||
contain a number of fields separated by commas. The fields in a line
|
||
are:
|
||
|
||
@example
|
||
category @r{The category of the item}
|
||
head @r{The headline, without TODO keyword, TAGS and PRIORITY}
|
||
type @r{The type of the agenda entry, can be}
|
||
todo @r{selected in TODO match}
|
||
tagsmatch @r{selected in tags match}
|
||
diary @r{imported from diary}
|
||
deadline @r{a deadline}
|
||
scheduled @r{scheduled}
|
||
timestamp @r{appointment, selected by timestamp}
|
||
closed @r{entry was closed on date}
|
||
upcoming-deadline @r{warning about nearing deadline}
|
||
past-scheduled @r{forwarded scheduled item}
|
||
block @r{entry has date block including date}
|
||
todo @r{The TODO keyword, if any}
|
||
tags @r{All tags including inherited ones, separated by colons}
|
||
date @r{The relevant date, like 2007-2-14}
|
||
time @r{The time, like 15:00-16:50}
|
||
extra @r{String with extra planning info}
|
||
priority-l @r{The priority letter if any was given}
|
||
priority-n @r{The computed numerical priority}
|
||
@end example
|
||
|
||
@noindent
|
||
Time and date will only be given if a timestamp (or deadline/scheduled)
|
||
led to the selection of the item.
|
||
|
||
A CSV list like this is very easy to use in a post-processing script.
|
||
For example, here is a Perl program that gets the TODO list from
|
||
Emacs/Org and prints all the items, preceded by a checkbox:
|
||
|
||
@example
|
||
#!/usr/bin/perl
|
||
|
||
# define the Emacs command to run
|
||
$cmd = "emacs -batch -l ~/.emacs -eval '(org-batch-agenda-csv \"t\")'";
|
||
|
||
# run it and capture the output
|
||
$agenda = qx@{$cmd 2>/dev/null@};
|
||
|
||
# loop over all lines
|
||
foreach $line (split(/\n/,$agenda)) @{
|
||
# get the individual values
|
||
($category,$head,$type,$todo,$tags,$date,$time,$extra,
|
||
$priority_l,$priority_n) = split(/,/,$line);
|
||
# process and print
|
||
print "[ ] $head\n";

this only looks at properties defined locally in the entry. If INHERIT
|

@defun org-entry-put-multivalued-property pom property &rest values
|

||
strings. They will be concatenated, with spaces as separators.
|
||
@end defun
|
||
|
||
@defun org-entry-get-multivalued-property pom property

@cindex mapping entries, API
|
||
|
||
Org has sophisticated mapping capabilities to find all entries satisfying
|
||
certain criteria. Internally, this functionality is used to produce agenda
|
||
views, but there is also an API that can be used to execute arbitrary
|
||
functions for each or selected entries. The main entry point for this API
|
||
is:
|
||
|
||
@defun org-map-entries func &optional match scope &rest skip
|
||
Call FUNC at each headline selected by MATCH in SCOPE.
|
||
|
||
FUNC is a function or a Lisp form. The function will be called without
|
||
arguments, with the cursor positioned at the beginning of the headline.
|
||
The return values of all calls to the function will be collected and
|
||
returned as a list.
|
||
|
||
The call to FUNC will be wrapped into a save-excursion form, so FUNC
|
||
does not need to preserve point. After evaluation, the cursor will be
|
||
moved to the end of the line (presumably of the headline of the
|
||
processed entry) and search continues from there. Under some
|
||
circumstances, this may not produce the wanted results. For example,
|
||
if you have removed (e.g.@: archived) the current (sub)tree it could
|
||
mean that the next entry will be skipped entirely. In such cases, you
|
||
can specify the position from where search should continue by making
|
||
FUNC set the variable `org-map-continue-from' to the desired buffer
|
||
position.
|
||
|
||
MATCH is a tags/property/todo match as it is used in the agenda match view.
|
||
Only headlines that are matched by this query will be considered during
|
||
the iteration. When MATCH is nil or t, all headlines will be
|
||
visited by the iteration.
|
||
|
||
SCOPE determines the scope of this command. It can be any of:
|
||
|
||
@example
|
||
nil @r{the current buffer, respecting the restriction if any}
|
||
tree @r{the subtree started with the entry at point}
|
||
region @r{The entries within the active region, if any}
|
||
file @r{the current buffer, without restriction}
|
||
file-with-archives
|
||
@r{the current buffer, and any archives associated with it}
|
||
agenda @r{all agenda files}
|
||
agenda-with-archives
|
||
@r{all agenda files with any archive files associated with them}
|
||
(file1 file2 ...)
|
||
@r{if this is a list, all files in the list will be scanned}
|
||
@end example
|
||
@noindent
|
||
The remaining args are treated as settings for the skipping facilities of
|
||
the scanner. The following items can be given here:
|
||
|
||
@vindex org-agenda-skip-function
|
||
@example
|
||
archive @r{skip trees with the archive tag}
|
||
comment @r{skip trees with the COMMENT keyword}
|
||
function or Lisp form
|
||
@r{will be used as value for @code{org-agenda-skip-function},}
|
||
@r{so whenever the function returns t, FUNC}
|
||
@r{will not be called for that entry and search will}
|
||
@r{continue from the point where the function leaves it}
|
||
@end example
|
||
@end defun
|
||
|
||
The function given to that mapping routine can really do anything you like.
|
||
It can use the property API (@pxref{Using the property API}) to gather more
|
||
information about the entry, or in order to change metadata in the entry.
|
||
Here are a couple of functions that might be handy:
|
||
|
||
@defun org-todo &optional arg
|
||
Change the TODO state of the entry. See the docstring of the functions for
|
||
the many possible values for the argument ARG.
|
||
@end defun
|
||
|
||
@defun org-priority &optional action
|
||
Change the priority of the entry. See the docstring of this function for the
|
||
possible values for ACTION.
|
||
@end defun
|
||
|
||
@defun org-toggle-tag tag &optional onoff
|
||
Toggle the tag TAG in the current entry. Setting ONOFF to either @code{on}
|
||
or @code{off} will not toggle tag, but ensure that it is either on or off.
|
||
@end defun
|
||
|
||
@defun org-promote
|
||
Promote the current entry.
|
||
@end defun
|
||
|
||
@defun org-demote
|
||
Demote the current entry.
|
||
@end defun
|
||
|
||
Here is a simple example that will turn all entries in the current file with
|
||
a tag @code{TOMORROW} into TODO entries with the keyword @code{UPCOMING}.
|
||
Entries in comment trees and in archive trees will be ignored.
|
||
|
||
@lisp
|
||
(org-map-entries
|
||
'(org-todo "UPCOMING")
|
||
"+TOMORROW" 'file 'archive 'comment)
|
||
@end lisp
|
||
|
||
The following example counts the number of entries with TODO keyword
|
||
@code{WAITING}, in all agenda files.
|
||
|
||
@lisp
|
||
(length (org-map-entries t "/+WAITING" 'agenda))

@uref{http://mobileorg.ncogni.to/, MobileOrg} is an application for the
|
||
@i{iPhone/iPod Touch} series of devices, developed by Richard Moreland.
|
||
@i{MobileOrg} offers offline viewing and capture support for an Org mode
|
||
system rooted on a ``real'' computer. It does also allow you to record
|
||
changes to existing entries. Android users should check out
|
||
@uref{http://wiki.github.com/matburt/mobileorg-android/, MobileOrg Android}
|
||
by Matt Jones.
|
||
|
||
This appendix describes the support Org has for creating agenda views in a
|
||
format that can be displayed by @i{MobileOrg}, and for integrating notes
|
||
captured and changes made by @i{MobileOrg} into the main system.
|
||
|
||
For changing tags and TODO states in MobileOrg, you should have set up the
|
||
customization variables @code{org-todo-keywords} and @code{org-tags-alist} to
|
||
cover all important tags and TODO keywords, even if individual files use only
|
||
part of these. MobileOrg will also offer you states and tags set up with
|
||
in-buffer settings, but it will understand the logistics of TODO state
|
||
@i{sets} (@pxref{Per-file keywords}) and @i{mutually exclusive} tags
|
||
(@pxref{Setting tags}) only for those set in these variables.

|
||
MobileOrg needs to interact with Emacs through a directory on a server. If you
|
||
are using a public server, you should consider to encrypt the files that are
|
||
uploaded to the server. This can be done with Org mode 7.02 and with
|
||
@i{MobileOrg 1.5} (iPhone version), and you need an @file{openssl}
|
||
installation on your system. To turn on encryption, set a password in
|
||
@i{MobileOrg} and, on the Emacs side, configure the variable
|
||
@code{org-mobile-use-encryption}@footnote{If you can safely store the
|
||
password in your Emacs setup, you might also want to configure
|
||
@code{org-mobile-encryption-password}. Please read the docstring of that
|
||
variable. Note that encryption will apply only to the contents of the
|
||
@file{.org} files. The file names themselves will remain visible.}.
|
||
|
||
The easiest way to create that directory is to use a free
|
||
@uref{http://dropbox.com,Dropbox.com} account@footnote{If you cannot use
|
||
Dropbox, or if your version of MobileOrg does not support it, you can use a
|
||
webdav server. For more information, check out the documentation of MobileOrg and also this
|
||
@uref{http://orgmode.org/worg/org-faq.html#mobileorg_webdav, FAQ entry}.}.
|
||
When MobileOrg first connects to your Dropbox, it will create a directory
|
||
@i{MobileOrg} inside the Dropbox. After the directory has been created, tell
|
||
Emacs about it:
|
||
|
||
@lisp
|
||
(setq org-mobile-directory "~/Dropbox/MobileOrg")
|
||
@end lisp
|
||
|
||
Org mode has commands to put files for @i{MobileOrg} into that directory,
|
||
and to read captured notes from there.
|
||
|
||
@node Pushing to MobileOrg, Pulling from MobileOrg, Setting up the staging area, MobileOrg
|
||
@section Pushing to MobileOrg
|
||
|
||
This operation copies all files currently listed in @code{org-mobile-files}
|
||
to the directory @code{org-mobile-directory}. By default this list contains
|
||
all agenda files (as listed in @code{org-agenda-files}), but additional files
|
||
can be included by customizing @code{org-mobile-files}. File names will be
|
||
staged with paths relative to @code{org-directory}, so all files should be
|
||
inside this directory. The push operation also creates a special Org file
|
||
@file{agendas.org} with all custom agenda view defined by the
|
||
user@footnote{While creating the agendas, Org mode will force ID properties
|
||
on all referenced entries, so that these entries can be uniquely identified
|
||
if @i{MobileOrg} flags them for further action. If you do not want to get
|
||
these properties in so many entries, you can set the variable
|
||
@code{org-mobile-force-id-on-agenda-items} to @code{nil}. Org mode will then
|
||
rely on outline paths, in the hope that these will be unique enough.}.
|
||
Finally, Org writes the file @file{index.org}, containing links to all other
|
||
files. @i{MobileOrg} first reads this file from the server, and then
|
||
downloads all agendas and Org files listed in it. To speed up the download,
|
||
MobileOrg will only read files whose checksums@footnote{stored automatically
|
||
in the file @file{checksums.dat}} have changed.

||
|
||
@node Pulling from MobileOrg, , Pushing to MobileOrg, MobileOrg

@section Pulling from MobileOrg
|
||
|
||
When @i{MobileOrg} synchronizes with the server, it not only pulls the Org
|
||
files for viewing. It also appends captured entries and pointers to flagged
|
||
and changed entries to the file @file{mobileorg.org} on the server. Org has
|
||
a @emph{pull} operation that integrates this information into an inbox file
|
||
and operates on the pointers to flagged entries. Here is how it works:
|
||
|
||
@enumerate
|
||
@item
|
||
Org moves all entries found in
|
||
@file{mobileorg.org}@footnote{@file{mobileorg.org} will be empty after this
|
||
operation.} and appends them to the file pointed to by the variable
|
||
@code{org-mobile-inbox-for-pull}. Each captured entry and each editing event
|
||
will be a top-level entry in the inbox file.
|
||
@item
|
||
After moving the entries, Org will attempt to implement the changes made in
|
||
@i{MobileOrg}. Some changes are applied directly and without user
|
||
interaction. Examples are all changes to tags, TODO state, headline and body
|
||
text that can be cleanly applied. Entries that have been flagged for further
|
||
action will receive a tag @code{:FLAGGED:}, so that they can be easily found
|
||
again. When there is a problem finding an entry or applying the change, the
|
||
pointer entry will remain in the inbox and will be marked with an error
|
||
message. You need to later resolve these issues by hand.
|
||
@item
|
||
Org will then generate an agenda view with all flagged entries. The user
|
||
should then go through these entries and do whatever actions are necessary.
|
||
If a note has been stored while flagging an entry in @i{MobileOrg}, that note
|
||
will be displayed in the echo area when the cursor is on the corresponding
|
||
agenda line.
|
||
@table @kbd
|
||
@kindex ?
|
||
@item ?
|
||
Pressing @kbd{?} in that special agenda will display the full flagging note in
|
||
another window and also push it onto the kill ring. So you could use @kbd{?
|
||
z C-y C-c C-c} to store that flagging note as a normal note in the entry.
|
||
Pressing @kbd{?} twice in succession will offer to remove the
|
||
@code{:FLAGGED:} tag along with the recorded flagging note (which is stored
|
||
in a property). In this way you indicate that the intended processing for
|
||
this flagged entry is finished.
|
||
@end table
|
||
@end enumerate
|
||
|
||
@kindex C-c a ?
|
||
If you are not able to process all flagged entries directly, you can always
|
||
return to this agenda view@footnote{Note, however, that there is a subtle
|
||
difference. The view created automatically by @kbd{M-x org-mobile-pull
|
||
@key{RET}} is guaranteed to search all files that have been addressed by the
|
||
last pull. This might include a file that is not currently in your list of

Org was born in 2003, out of frustration over the user interface of the Emacs
|
||
Outline mode. I was trying to organize my notes and projects, and using
|
||
Emacs seemed to be the natural way to go. However, having to remember eleven
|
||
different commands with two or three keys per command, only to hide and show
|
||
parts of the outline tree, that seemed entirely unacceptable to me. Also,
|
||
when using outlines to take notes, I constantly wanted to restructure the
|
||
tree, organizing it parallel to my thoughts and plans. @emph{Visibility
|
||
cycling} and @emph{structure editing} were originally implemented in the
|
||
package @file{outline-magic.el}, but quickly moved to the more general
|
||
@file{org.el}. As this environment became comfortable for project planning,
|
||
the next step was adding @emph{TODO entries}, basic @emph{timestamps}, and
|
||
@emph{table support}. These areas highlighted the two main goals that Org
|
||
still has today: to be a new, outline-based, plain text mode with innovative
|
||
and intuitive editing features, and to incorporate project planning
|
||
functionality directly into a notes file.
|
||
|
||
Since the first release, literally thousands of emails to me or to
|
||
@email{emacs-orgmode@@gnu.org} have provided a constant stream of bug
|
||
reports, feedback, new ideas, and sometimes patches and add-on code.
|
||
Many thanks to everyone who has helped to improve this package. I am
|
||
trying to keep here a list of the people who had significant influence
|
||
in shaping one or more aspects of Org. The list may not be
|
||
complete, if I have forgotten someone, please accept my apologies and
|
||
let me know.
|
||
|
||
Before I get to this list, a few special mentions are in order:
|
||
|
||
@table @i
|
||
@item Bastien Guerry
|
||
Bastien has written a large number of extensions to Org (most of them
|
||
integrated into the core by now), including the @LaTeX{} exporter and the plain
|
||
list parser. His support during the early days, when he basically acted as
|
||
co-maintainer, was central to the success of this project. Bastien also
|
||
invented Worg, helped establishing the Web presence of Org, and sponsors
|
||
hosting costs for the orgmode.org website.
|
||
@item Eric Schulte and Dan Davison
|
||
Eric and Dan are jointly responsible for the Org-babel system, which turns
|
||
Org into a multi-language environment for evaluating code and doing literate
|
||
programming and reproducible research.
|
||
@item John Wiegley
|
||
John has contributed a number of great ideas and patches directly to Org,
|
||
including the attachment system (@file{org-attach.el}), integration with
|
||
Apple Mail (@file{org-mac-message.el}), hierarchical dependencies of TODO
|
||
items, habit tracking (@file{org-habits.el}), and encryption
|
||
(@file{org-crypt.el}). Also, the capture system is really an extended copy
|
||
of his great @file{remember.el}.
|
||
@item Sebastian Rose
|
||
Without Sebastian, the HTML/XHTML publishing of Org would be the pitiful work
|
||
of an ignorant amateur. Sebastian has pushed this part of Org onto a much
|
||
higher level. He also wrote @file{org-info.js}, a Java script for displaying
|
||
webpages derived from Org using an Info-like or a folding interface with
|
||
single-key navigation.
|
||
