This commit add a new face for footnote labels, and activates footnote
labels for mouse clicks and for `C-c C-o', to jump to the
corresponding reference or definition.
This patch implements fully automatic creation of unique labels for
footnotes, which is also turned on as the default setting. The
automatic labels look like [fn:1], [fn:2], etc, using the first
available unused number.
The commit introduces a new variable, `org-footnote-auto-label' with a
number of different options ranging from no auto creation (prompting
the user for a label) to fully automatic creation.
Also, the commit introduces new #+STARTUP options that can be used to
select these settings on a per-file basis.
A new perl program, list-hooks.pl, now extracts the full list of hook
and function variables in Org, for inclusion into Worg's org-hooks.org.
Also, add a docstring to a few hooks that did not have one.
This patch adds support functionality for the new code references. It
makes sure that `C-c C-o' will follow a code reference correctly. It
also extends the command org-store-link to actually create a new code
reference cookie when used in a source code temporary buffer created
with "C-c '". The new link will be stored, so that it can be inserted
with `C-c C-l'. When inserting such a link, no description will be
prompted for, because these coderef links should best not have a
description part.
This patch covers the three main backends, html, latex, and ascii. It
adds the code to make sure the coderef links identified by the
preprocessing will be implemented correctly when a backend does its work.
When refiling to the current file, the completion commands do not show
the file name. This was broken because I had switched from comparing
truenames to normal names. Now I am using expanded names, this is fast
and works well.
This patch introduces three improvements to refile target construction,
which should speed these functions up significantly.
1. A faster way to move up a level in the outline hierarchy
2. A better way to construct the outline path, in the case
that the command is scanning the entire hierarchy anyway
3. Avoid comparing the true-names of files.
Unique identifiers for entries can now be used more efficiently.
Internally, a hash array has replaced the alist used so far to
keep track of the files in which an ID is defined. This makes it
quite fast to find an entry by ID.
There is now a new link type which looks like this:
id:GLOBALLY-UNIQUE-IDENTIFIER
This link points to a specific entry. When you move the entry to
a different file, for example if you move it to an archive
file, this link will continue to work.
The file /org-id.el/ contains an API that can be used to write
code using these identifiers, including creating IDs and finding
them wherever they are.
Org has its own method to create unique identifiers, but if the
system has /uuidgen/ command installed (Mac's and Linux systems
generally do), it will be used by default. You an also select
the method by hand, using the variable =org-id-method=.
If the ID system ever gets confused about where a certain ID is,
it initiates a global scan of all agenda files with associated
archives, all files previously known containing any IDs, and all
currently visited Org-mode files to rebuild the hash. You can
also initiate this by hand: =M-x org-id-update-id-locations=.
Running this command will also dump into the =*Messages*= buffer
information about any duplicate IDs. These should not exist, but
if you /copy/ an entry with its properties, duplicate IDs will
inevitably be produced. This is unavoidable in a plain text
system that allows you to edit the text in arbitrary ways, and a
portion of care on your side is needed to keep this system clean.
The hash is stored in the file =~/.emacs.d/.org-id-locations=.
This is also a change from previous versions where the file was
=~/.org=id-locations=. Therefore, you can remove this old file
if you have it. I am not sure what will happen if the =.emacs.d=
directory does not exists in your setup, but in modern Emacsen, I
believe it should exist. If you do not want to use IDs across
files, you can avoid the overhead with tracking IDs by
customizing the variable =org-id-track-globally=. IDs can then
still be used for links inside a single file.
IDs will also be used when you create a new link to an Org-mode
buffer. If you use =org-store-link= (normally at =C-c l=) inside
en entry in an Org-mode buffer, and ID property will be created
if it does not exist, and the stored link will be an =id:= link.
If you prefer the much less secure linking to headline text, you
can configure the variable =org-link-to-org-use-id=. The default
setting for this variable is =create-if-interactive=, meaning
that an ID will be created when you store a link interactively,
but not if you happen to be in an Org-mode file while you create
a remember note (which usually has a link to the place where you
were when starting remember).
Tables, and Hyperlinks that represent inlined images, can now be
equipped with additional information that will be used during
export. The information will be taken from the following special
lines in the buffer and apply to the first following table or
link.
- #+CAPTION: :: The caption of the image or table. This string
should be processed according to the export backend, but
this is not yet done.
- #+LABEL: :: A label to identify the figure/table for cross
references. For HTML export, this string will become the
ID for the `<div class="figure">' element that encapsulates
the image tag and the caption. For LaTeX export, this
string will be used as the argument of a `\label{...}'
macro. These lables will be available for internal links
like `[[label][Table] ]'.
- #+ATTR_HTML: :: Attributes for HTML export of image, to be
added as attributes into the `<img...>' tag. This string
will not be processed, so it should have immediately the
right format.
- #+ATTR_LaTeX: :: Attributes for LaTeX export of images, to
be inserted into the optional argument of the
`\includegraphics[...]{file}' command, to specify scaling,
clipping and other options. This string will not be
processed, so it should have immediately the right
format, like `width=5cm,angle=90'
For LaTeX export, if either a caption or a label is given, the
element will be exported as a float, i.e. wrapped into a figure
or table environment.
Moving trees up or down with XEmacs caused a problem when the tree is
at the beginning if the buffer or narrowed region. This patch
protects the relevant calls to outline-flag-region so that they are
only executed if the range is valid.
