This file is about changes in Emacs version 24.
|
||
|
||
See files NEWS.23, NEWS.22, NEWS.21, NEWS.20, NEWS.19, NEWS.18,
|
||
and NEWS.1-17 for changes in older Emacs versions.
|
||
|
||
You can narrow news to a specific version by calling `view-emacs-news'
|
||
with a prefix argument or by typing C-u C-h C-n.
|
||
|
||
Temporary note:
|
||
+++ indicates that the appropriate manual has already been updated.
|
||
--- means no change in the manuals is called for.
|
||
When you add a new item, please add it without either +++ or ---
|
||
so we will look at it and add it to the manual.

|
||
|
||
** Calc
|
||
|
||
*** Calc by default now uses the Gregorian calendar for all dates, and
|
||
uses January 1, 1 AD as its day number 1. Previously Calc used the
|
||
Julian calendar for dates before September 14, 1752, and it used
|
||
December 31, 1 BC as its day number 1; the new scheme is more
|
||
consistent with Calendar's calendrical system and day numbering.
|
||
|
||
*** The new variable `calc-gregorian-switch' lets you configure the
|
||
date when Calc switches from the Julian to the Gregorian calendar.
|
||
Nil, the default value, means to always use the Gregorian calendar.
|
||
The value (YEAR MONTH DAY) means to start using the Gregorian calendar
|
||
on the given date.
|
||
|
||
** ERC
|
||
|
||
*** New option `erc-accidental-paste-threshold-seconds'.
|
||
If set to a number, this can be used to avoid accidentally paste large
|
||
amounts of data into the ERC input.
|
||
|
||
** Icomplete is a bit more like IDO.
|
||
*** key bindings to navigate through and select the completions.
|
||
*** The icomplete-separator is customizable, and its default has changed.
|
||
*** Removed icomplete-show-key-bindings.
|
||
|
||
** MH-E has been updated to MH-E version 8.4.
|
||
See MH-E-NEWS for details.
|
||
|
||
+++
|
||
** New function `ses-rename-cell' to give SES cells arbitrary names.
|
||
|
||
** trace-function was largely rewritten.
|
||
New features include:
|
||
- no prompting for the destination buffer, unless a prefix-arg was used.
|
||
- additionally to prompting for a destination buffer, when a prefix-arg is
|
||
used, the user can enter a "context", i.e. Lisp expression whose value at the
|
||
time the function is entered/exited will be printed along with the function
|
||
name and arguments. Useful to trace the value of (current-buffer) or
|
||
(point) when the function is invoked.
|
||
|
||
** New command `delete-duplicate-lines' has two types of operation:
|
||
when its arg ADJACENT is non-nil (when called interactively with C-u C-u)
|
||
it works like the utility `uniq'. Otherwise by default it deletes
|
||
duplicate lines everywhere in the region without regard to adjacency.
|
||
|
||
** Tramp
|
||
+++
|
||
*** New connection method "adb", which allows to access Android
|
||
devices by the Android Debug Bridge. The variable `tramp-adb-sdk-dir'
|
||
must be set to the Android SDK installation directory.
|
||
|
||
** Woman
|
||
|
||
*** The commands `woman-default-faces' and `woman-monochrome-faces'
|
||
are obsolete. Customize the `woman-* faces instead.
|
||
|
||
** Obsolete packages:
|
||
|
||
*** longlines.el is obsolete; use visual-line-mode instead.
|
||
|
||
*** terminal.el is obsolete; use term.el instead.
|
||
|
||
|
||
* New Modes and Packages in Emacs 24.4
|
||
** New nadvice.el package offering lighter-weight advice facilities.
|
||
It is layered as:
|
||
- add-function/remove-function which can be used to add/remove code on any
|
||
function-carrying place, such as process-filters or `<foo>-function' hooks.
|
||
- advice-add/advice-remove to add/remove a piece of advice on a named function,
|
||
much like `defadvice' does.
|
||
|
||
* Incompatible Lisp Changes in Emacs 24.4
|
||
|
||
** nil and "unbound" are indistinguishable in symbol-function.
|
||
`symbol-function' never signals `void-function' any more.
|
||
`fboundp' returns non-nil if the symbol was `fset' to nil.
|
||
|
||
** `defadvice' does not honor the `freeze' flag and cannot advise
|
||
special-forms any more.
|
||
|
||
** `dolist' in lexical-binding mode does not bind VAR in RESULT any more.
|
||
VAR was bound to nil which was not tremendously useful and just lead to
|
||
spurious warnings about an unused var.
|
||
|
||
* Lisp changes in Emacs 24.4
|
||
|
||
** Face changes
|
||
|
||
*** The `face-spec-set' is now analogous to `setq' for face specs.
|
||
Its third arg now accepts values specifying exactly which face spec to
|
||
set (defface, custom, or user spec), and it directly sets the relevant
|
||
property using the supplied face spec.
|
||
|
||
*** Face specs set via Custom themes now replace the `defface' spec
|
||
rather than inheriting from it (as do face specs set via Customize).
|
||
|
||
** time-to-seconds is not obsolete any more.
|
||
** New function special-form-p.
|
||
** Docstrings can be made dynamic by adding a `dynamic-docstring-function'
|
||
text-property on the first char.
|
||
|
||
** The `defalias-fset-function' property lets you catch calls to defalias
|
||
and redirect them to your own function instead of `fset'.
|
||
|
||
* Changes in Emacs 24.4 on non-free operating systems
|
||
|
||
+++
|
||
** The "generate a backtrace on fatal error" feature now works on MS Windows.
|
||
The backtrace is written to the 'emacs_backtrace.txt' file in the
|
||
directory where Emacs was running.
|
||
|
||
|
||
* Installation Changes in Emacs 24.3
|
||
|
||
---
|
||
** The default toolkit has been changed to Gtk+ version 3.
|
||
If you don't pass --with-x-toolkit to configure or if you pass
|
||
--with-x-toolkit=gtk or --with-x-toolkit=yes, configure will try to build
|
||
with Gtk+ version 3, and if that fails, try Gtk+ version 2.
|
||
You can explicitly require a specific version by passing
|
||
--with-x-toolkit=gtk2 or --with-x-toolkit=gtk3 to configure.
|
||
|
||
---
|
||
** New configure option '--without-all' to disable additional features.
|
||
This disables most of the features that are normally enabled by default.
|
||
|
||
---
|
||
** New configure option '--enable-link-time-optimization' to utilize
|
||
an appropriate feature provided by GCC since version 4.5.0.
|
||
|
||
---
|
||
** New configure option '--enable-gcc-warnings', intended for developers.
|
||
If building with GCC, this enables compile-time checks that warn about
|
||
possibly-questionable C code. On a recent GNU system there should be
|
||
no warnings; on older and on non-GNU systems the generated warnings
|
||
may be useful.
|
||
|
||
---
|
||
** The configure option '--enable-use-lisp-union-type' has been
|
||
renamed to '--enable-check-lisp-object-type', as the resulting
|
||
Lisp_Object type no longer uses a union to implement the compile time
|
||
check that this option enables.
|
||
|
||
---
|
||
** The configure option '--disable-maintainer-mode' has been removed,
|
||
as it was confusingly-named and rarely useful.
|
||
|
||
---
|
||
** You can use `NO_BIN_LINK=t make install' to prevent the installation
|
||
overwriting "emacs" in the installation bin/ directory with a link
|
||
to emacs-VERSION.
|
||
|
||
---
|
||
** The configure options `--program-prefix', `--program-suffix', and
|
||
`--program-transform-name' apply to more than just the installed
|
||
binaries. Now they also affect the man pages, icons, and the
|
||
etc/emacs.desktop file; but not the info pages, since this would break
|
||
links between the various manuals.
|
||
|
||
---
|
||
** Emacs uses libtinfo in preference to libncurses, if available.
|
||
|
||
---
|
||
** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and
|
||
/usr/pkg/lib to the linker search path. You must add them yourself if
|
||
you want them.
|
||
|
||
---
|
||
** The standalone scripts rcs-checkin and vcdiff have been removed
|
||
(from the bin and libexec directories, respectively). The former is
|
||
no longer relevant, the latter is replaced by lisp (in vc-sccs.el).
|
||
|
||
|
||
* Startup Changes in Emacs 24.3
|
||
|
||
+++
|
||
** Emacs no longer searches for `leim-list.el' files beneath the standard
|
||
lisp/ directory. There should not be any there anyway. If you have
|
||
been adding them there, put them somewhere else, eg site-lisp.
|
||
|
||
---
|
||
** The `--no-site-lisp' command line option now works for Nextstep builds.
|
||
|
||
|
||
* Changes in Emacs 24.3
|
||
|
||
+++
|
||
** Most y-or-n prompts now allow you to scroll the selected window.
|
||
Typing C-v or M-v at a y-or-n prompt scrolls forward or backward
|
||
respectively, without exiting from the prompt.
|
||
|
||
** Mode line changes
|
||
---
|
||
*** New option `mode-line-default-help-echo' specifies the help text
|
||
(shown in a tooltip or in the echo area) for any part of the mode line
|
||
that does not have its own specialized help text.
|
||
+++
|
||
*** You can now click mouse-3 in the coding system indicator to invoke
|
||
`set-buffer-file-coding-system'.
|
||
|
||
** Help changes
|
||
|
||
+++
|
||
*** `C-h f' (describe-function) can now perform autoloading.
|
||
When this command is called for an autoloaded function whose docstring
|
||
contains a key substitution construct, that function's library is
|
||
automatically loaded, so that the documentation can be shown
|
||
correctly. To disable this, set `help-enable-auto-load' to nil.
|
||
|
||
---
|
||
*** `C-h f' now reports previously-autoloaded functions as "autoloaded",
|
||
even after their associated libraries have been loaded (and the
|
||
autoloads have been redefined as functions).
|
||
|
||
** Minibuffer changes
|
||
---
|
||
*** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
|
||
next and previous path separator, respectively.
|
||
+++
|
||
*** minibuffer-electric-default-mode can rewrite (default ...) to [...].
|
||
Just set minibuffer-eldef-shorten-default to t before enabling the mode.
|
||
|
||
+++
|
||
** ImageMagick support, if available, is automatically enabled.
|
||
It is no longer necessary to call `imagemagick-register-types'
|
||
explicitly to install ImageMagick image types; that function is called
|
||
automatically at startup, or when customizing an imagemagick- option.
|
||
+++
|
||
*** Setting `imagemagick-types-inhibit' to t now disables the use of
|
||
ImageMagick to view images. You must call imagemagick-register-types
|
||
afterwards if you do not use customize to change this.
|
||
+++
|
||
*** The new variable `imagemagick-enabled-types' also affects which
|
||
ImageMagick types are treated as images. The function
|
||
`imagemagick-filter-types' returns the list of types that will be
|
||
treated as images.
|
||
---
|
||
*** Images displayed via ImageMagick now support transparency and the
|
||
:background image spec property.
|
||
|
||
** Server and client changes
|
||
+++
|
||
*** emacsclient now obeys string values for `initial-buffer-choice',
|
||
if it is told to open a new frame without specifying any file to visit
|
||
or expression to evaluate.
|
||
---
|
||
*** New option `server-auth-key' specifies a shared server key.
|
||
|
||
+++
|
||
** In the Package Menu, newly-available packages are listed as "new",
|
||
and sorted above the other "available" packages by default.
|
||
|
||
+++
|
||
** `C-x C-q' is now bound to the new minor mode `read-only-mode'.
|
||
This minor mode replaces `toggle-read-only', which is now obsolete.
|
||
|
||
+++
|
||
** Emacs now generates backtraces on fatal errors.
|
||
On encountering a fatal error, Emacs now outputs a textual description
|
||
of the fatal signal, and a short backtrace on platforms like glibc
|
||
that support backtraces.
|
||
|
||
---
|
||
** If your Emacs was built from a bzr checkout, the new variable
|
||
`emacs-bzr-version' contains information about the bzr revision used.
|
||
|
||
+++
|
||
** New variable `create-lockfiles' specifies usage of lockfiles.
|
||
It defaults to t. Changing it to nil inhibits the creation of lock
|
||
files (use this with caution).
|
||
|
||
+++
|
||
** Using "unibyte: t" in Lisp source files is obsolete.
|
||
Use "coding: raw-text" instead.
|
||
|
||
+++
|
||
** Setting `enable-remote-dir-locals' to non-nil allows directory
|
||
local variables on remote hosts.
|
||
|
||
---
|
||
** The entry for PCL-CVS has been removed from the Tools menu.
|
||
The PCL-CVS commands are still available via the keyboard.
|
||
|
||
** Internationalization changes
|
||
---
|
||
*** New language environment: Persian.
|
||
---
|
||
*** New input method `vietnamese-vni'.
|
||
|
||
** Nextstep (GNUstep / Mac OS X) port changes
|
||
---
|
||
*** Fullscreen and frame parameter fullscreen is supported.
|
||
---
|
||
*** A file dialog is used for open/save operations initiated from the
|
||
menu/toolbar.
|
||
|
||
|
||
* Editing Changes in Emacs 24.3
|
||
|
||
** Navigation command changes
|
||
+++
|
||
*** New binding `M-g c' for `goto-char'.
|
||
+++
|
||
*** New binding `M-g TAB' for `move-to-column'.
|
||
+++
|
||
*** `M-g TAB' (`move-to-column') prompts for a column number if called
|
||
interactively with no prefix arg. Previously, it moved to column 1.
|
||
|
||
** Search and Replace changes
|
||
+++
|
||
*** Non-regexp Isearch now performs "lax" space matching.
|
||
Each sequence of spaces in the supplied search string may match any
|
||
sequence of one or more whitespace characters, as specified by the
|
||
variable `search-whitespace-regexp'. (This variable is also used by a
|
||
similar existing feature for regexp Isearch).
|
||
+++
|
||
*** New Isearch command `M-s SPC' toggles lax space matching.
|
||
This applies to both ordinary and regexp Isearch.
|
||
+++
|
||
*** New option `replace-lax-whitespace'.
|
||
If non-nil, `query-replace' uses flexible whitespace matching too.
|
||
The default is nil.
|
||
+++
|
||
*** Global `M-s _' starts a symbol (identifier) incremental search,
|
||
and `M-s _' in Isearch toggles symbol search mode.
|
||
`M-s c' in Isearch toggles search case-sensitivity.
|
||
|
||
+++
|
||
** `C-x 8 RET' is now bound to `insert-char', which is now a command.
|
||
`ucs-insert' is now an obsolete alias for `insert-char'.
|
||
|
||
---
|
||
** The `z' key no longer has a binding in most special modes.
|
||
It used to be bound to `kill-this-buffer', but `z' is too easy to
|
||
accidentally type.
|
||
|
||
+++
|
||
** New option `delete-trailing-lines' specifies whether
|
||
M-x delete-trailing-whitespace should delete trailing lines at the end
|
||
of the buffer. It defaults to t.
|
||
|
||
** Register changes
|
||
+++
|
||
*** `C-x r +' is now overloaded to invoke `append-to-register.
|
||
+++
|
||
*** New option `register-separator' specifies the register containing
|
||
the text to put between collected texts for use with M-x
|
||
append-to-register and M-x prepend-to-register.
|
||
|
||
+++
|
||
** `C-u M-=' now counts lines/words/characters in the entire buffer.
|
||
|
||
+++
|
||
** New command `C-x r M-w' (copy-rectangle-as-kill).
|
||
It copies the region-rectangle as the last rectangle kill.
|
||
|
||
+++
|
||
** New option `yank-handled-properties' allows processing of text
|
||
properties on yanked text, in more ways that are more general than
|
||
just removing them, as done by `yank-excluded-properties'.
|
||
|
||
|
||
* Changes in Specialized Modes and Packages in Emacs 24.3
|
||
|
||
** Apropos
|
||
---
|
||
*** The faces used by Apropos are now directly customizable.
|
||
These faces are named `apropos-symbol', `apropos-keybinding', and so on;
|
||
see the `apropos' Custom group for details.
|
||
---
|
||
*** The old options whose values specified faces to use were removed
|
||
(i.e. `apropos-symbol-face', `apropos-keybinding-face', etc.).
|
||
|
||
** Buffer Menu
|
||
This package has been rewritten to use Tabulated List mode.
|
||
---
|
||
*** Option `Buffer-menu-buffer+size-width' is now obsolete.
|
||
Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead.
|
||
|
||
** Calendar
|
||
|
||
+++
|
||
*** You can customize the header text that appears above each calendar month.
|
||
See the variable `calendar-month-header'.
|
||
|
||
+++
|
||
*** New LaTeX calendar style, produced by `cal-tex-cursor-week2-summary'.
|
||
|
||
+++
|
||
*** The calendars produced by cal-html include holidays.
|
||
Customize `cal-html-holidays' to change this.
|
||
|
||
** CL
|
||
|
||
+++
|
||
*** CL's main entry is now (require 'cl-lib).
|
||
`cl-lib' is like the old `cl' except that it uses the namespace cleanly,
|
||
i.e. all its definitions have the "cl-" prefix (and internal definitions use
|
||
the "cl--" prefix).
|
||
|
||
If `cl' provided a feature under the name `foo', then `cl-lib' provides it
|
||
under the name `cl-foo' instead, with the exceptions of the few definitions
|
||
that had to use `foo*' to avoid conflicts with pre-existing Elisp entities,
|
||
which have not been renamed to `cl-foo*' but just `cl-foo'.
|
||
|
||
The old `cl' is now deprecated and is mainly just a bunch of aliases that
|
||
provide the old non-prefixed names. Some exceptions are listed below.
|
||
|
||
+++
|
||
*** `cl-flet' is not like `flet' (which is deprecated).
|
||
Instead it obeys the behavior of Common-Lisp's `flet'.
|
||
In particular, in cl-flet function definitions are lexically scoped,
|
||
whereas in flet the scoping is dynamic.
|
||
|
||
+++
|
||
*** `cl-labels' is slightly different from `labels'.
|
||
The difference is that it relies on the `lexical-binding' machinery (as opposed
|
||
to the `lexical-let' machinery used previously) to capture definitions in
|
||
closures, so such closures will only work if `lexical-binding' is in use.
|
||
|
||
+++
|
||
*** `cl-letf' is not exactly like `letf'.
|
||
The only difference is in details that relate to some deprecated usage
|
||
of `symbol-function' in place forms.
|
||
|
||
+++
|
||
*** `progv' was rewritten to use the `let' machinery.
|
||
A side effect is that vars without corresponding value are bound to nil
|
||
rather than making them unbound.
|
||
|
||
+++
|
||
*** The following methods of extending `setf' are obsolete
|
||
(use features from gv.el instead):
|
||
`define-modify-macro' (use `gv-letplace')
|
||
`defsetf' (use `gv-define-simple-setter' or `gv-define-setter')
|
||
`define-setf-expander' (use `gv-define-setter' or `gv-define-expander')
|
||
`get-setf-method' no longer exists (see "Incompatible Lisp Changes")
|
||
|
||
+++
|
||
** New compilation option `compilation-always-kill'.
|
||
|
||
** Customize
|
||
---
|
||
*** `custom-reset-button-menu' now defaults to t.
|
||
---
|
||
*** Non-option variables are never matched in `customize-apropos' and
|
||
`customize-apropos-options' (i.e. the prefix argument does nothing for
|
||
these commands now).
|
||
|
||
---
|
||
** `desktop-path' no longer includes the "." directory.
|
||
Desktop files are now located in ~/.emacs.d by default.
|
||
|
||
** D-Bus
|
||
|
||
+++
|
||
*** New variables `dbus-compiled-version' and `dbus-runtime-version'.
|
||
|
||
+++
|
||
*** The D-Bus object manager interface is implemented.
|
||
|
||
+++
|
||
*** Variables of type :(u)int32 and :(u)int64 accept floating points,
|
||
if their value does not fit into Emacs's integer range.
|
||
|
||
+++
|
||
*** The function `dbus-call-method' works non-blocking now, it can be
|
||
interrupted by C-g. `dbus-call-method-non-blocking' is obsolete.
|
||
|
||
+++
|
||
*** Signals can be sent also as unicast message.
|
||
|
||
+++
|
||
*** The argument list of `dbus-register-signal' has been extended,
|
||
according to the new match rule types of D-Bus. See the manual for
|
||
details.
|
||
|
||
+++
|
||
*** `dbus-init-bus' supports private connections.
|
||
|
||
+++
|
||
*** There is a new function `dbus-setenv'.
|
||
|
||
** Diff mode
|
||
|
||
---
|
||
*** Changes are now highlighted using the same color scheme as in
|
||
modern VCSes. Deletions are displayed in red (new faces
|
||
`diff-refine-removed' and `smerge-refined-removed', and new definition
|
||
of `diff-removed'), insertions in green (new faces `diff-refine-added'
|
||
and `smerge-refined-added', and new definition of `diff-added').
|
||
|
||
---
|
||
*** The variable `diff-use-changed-face' defines whether to use the
|
||
face `diff-changed', or `diff-removed' and `diff-added' to highlight
|
||
changes in context diffs.
|
||
|
||
+++
|
||
*** The new command `diff-delete-trailing-whitespace' removes trailing
|
||
whitespace introduced by a diff.
|
||
|
||
** Dired
|
||
+++
|
||
*** `dired-do-async-shell-command' executes each file sequentially
|
||
if the command ends in `;' (when operating on multiple files).
|
||
Otherwise, it executes the command on each file in parallel.
|
||
---
|
||
*** Typing M-n in the minibuffer of `dired-do-chmod', `dired-do-chgrp',
|
||
`dired-do-chown', `dired-do-touch' pulls the file attributes of the
|
||
file at point.
|
||
+++
|
||
*** When the region is active, `m' (`dired-mark'), `u' (`dired-unmark'),
|
||
`DEL' (`dired-unmark-backward'), `d' (`dired-flag-file-deletion')
|
||
mark/unmark/flag all files in the active region.
|
||
+++
|
||
*** The minibuffer default for `=' (`dired-diff) has changed.
|
||
It is now the backup file for the file at point, if one exists.
|
||
In Transient Mark mode the default is the file at the active mark.
|
||
+++
|
||
*** `M-=' is no longer bound to `dired-backup-diff' in Dired buffers.
|
||
The global binding for `M-=', `count-words-region' is in effect.
|
||
|
||
---
|
||
** Ediff now uses the same color scheme as Diff mode.
|
||
|
||
** ERC
|
||
|
||
+++
|
||
*** New module "notifications", which can send a notification when you
|
||
receive a private message or your nickname is mentioned.
|
||
|
||
+++
|
||
*** ERC will look up server/channel names via auth-source and use any
|
||
channel keys found.
|
||
|
||
+++
|
||
*** New option `erc-lurker-hide-list', similar to `erc-hide-list', but
|
||
only applies to messages sent by lurkers.
|
||
|
||
+++
|
||
** Flymake uses fringe bitmaps to indicate errors and warnings.
|
||
See `flymake-fringe-indicator-position', `flymake-error-bitmap' and
|
||
`flymake-warning-bitmap'.
|
||
|
||
---
|
||
** Follow mode no longer works by using advice.
|
||
The option `follow-intercept-processes' has been removed.
|
||
|
||
---
|
||
** The FFAP option `ffap-url-unwrap-remote' can now be a list of strings,
|
||
specifying URL types that should be converted to remote file names at
|
||
the FFAP prompt. The default is now '("ftp").
|
||
|
||
---
|
||
** New Ibuffer `derived-mode' filter, bound to `/ M'.
|
||
The old binding for `/ M' (filter by used-mode) is now bound to `/ m'.
|
||
|
||
---
|
||
** `javascript-generic-mode' is now an obsolete alias for `js-mode'.
|
||
|
||
+++
|
||
** New option `mouse-avoidance-banish-position' specifies where the
|
||
`banish' mouse avoidance setting moves the mouse.
|
||
|
||
+++
|
||
** notifications.el supports now version 1.2 of the Notifications API.
|
||
The function `notifications-get-capabilities' returns the supported
|
||
server properties.
|
||
|
||
---
|
||
** In Perl mode, new option `perl-indent-parens-as-block' causes non-block
|
||
closing brackets to be aligned with the line of the opening bracket.
|
||
|
||
---
|
||
** In Proced mode, new command `proced-renice' renices marked processes.
|
||
|
||
---
|
||
** Python mode
|
||
|
||
A new version of python.el, which provides several new features, including:
|
||
per-buffer shells, better indentation, Python 3 support, and improved
|
||
shell-interaction compatible with iPython (and virtually any other
|
||
text based shell).
|
||
|
||
*** Some user options have been replaced/renamed:
|
||
Old defcustom: | New defcustom:
|
||
python-indent | python-indent-offset
|
||
python-guess-indent | python-indent-guess-indent-offset
|
||
python-pdbtrack-do-tracking-p | python-pdbtrack-activate
|
||
python-use-skeletons | python-skeleton-autoinsert
|
||
|
||
*** Some user options have been removed:
|
||
|
||
**** `python-indent-string-contents': Strings are never indented.
|
||
|
||
**** `python-honour-comment-indentation':
|
||
Comments are never considered as indentation markers themselves.
|
||
|
||
**** `python-continuation-offset': Indentation is automatically
|
||
calculated in a pep8 compliant way depending on the context.
|
||
|
||
**** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist':
|
||
Have no direct mapping as the shell interaction is completely different.
|
||
|
||
**** `python-python-command', `python-jython-command':
|
||
Replaced by `python-shell-interpreter'.
|
||
|
||
**** `inferior-python-filter-regexp', `python-remove-cwd-from-path',
|
||
`python-pdbtrack-minor-mode-string', `python-source-modes':
|
||
No longer relevant.
|

||
** reStructuredText mode
|
||
|
||
*** Keybindings (see `C-c C-h'), TAB indentation, filling and auto-filling,
|
||
fontification, comment handling, and customization have all been revised
|
||
and improved.
|
||
|
||
*** Support for `imenu' and `which-function-mode'.
|
||
|
||
*** The reStructuredText syntax is more closely covered.
|
||
Sphinx support has been improved.
|
||
|
||
*** `rst-insert-list' inserts new list or continues existing lists.
|
||
|
||
*** A negative prefix argument always works for `rst-adjust'.
|
||
|
||
*** The window configuration is reset after displaying a TOC.
|
||
|
||
*** The constant `rst-version' describes the rst.el package version.
|
||
|
||
---
|
||
** Shell Script mode
|
||
|
||
*** Pairing of parens/quotes uses electric-pair-mode instead of skeleton-pair.
|
||
|
||
*** `sh-electric-here-document-mode' now controls auto-insertion of here-docs.
|
||
|
||
*** `sh-use-smie' lets you choose a new indentation and navigation code.
|
||
|
||
+++
|
||
** New option `async-shell-command-buffer' specifies the buffer to use
|
||
for a new asynchronous `shell-command' when the default output buffer
|
||
`*Async Shell Command*' is already in use.
|
||
|
||
---
|
||
** SQL mode has a new option `sql-db2-escape-newlines'.
|
||
If non-nil, newlines sent to the command interpreter will be escaped
|
||
by a backslash. The default does not escape the newlines and assumes
|
||
that the sql statement will be terminated by a semicolon.
|
||
|
||
** Tabulated List and packages derived from it
|
||
+++
|
||
*** New command `tabulated-list-sort', bound to `S', sorts the column
|
||
at point, or the Nth column if a numeric prefix argument is given.
|
||
|
||
** Term
|
||
+++
|
||
*** The variables `term-default-fg-color' and `term-default-bg-color' are
|
||
now deprecated in favor of the customizable face `term'.
|
||
+++
|
||
*** You can customize how to display ANSI terminal colors and styles
|
||
by customizing the corresponding `term-color-<COLOR>',
|
||
`term-color-underline' and `term-color-bold' faces.
|
||
|
||
** Tramp
|
||
+++
|
||
*** The syntax has been extended in order to allow ad-hoc proxy definitions.
|
||
See the manual for details.
|
||
+++
|
||
*** Remote processes are now supported also on remote Windows host.
|
||
|
||
** URL
|
||
+++
|
||
*** Structs made by `url-generic-parse-url' have nil `attributes' slot.
|
||
Previously, this slot stored semicolon-separated attribute-value pairs
|
||
appended to some imap URLs, but this is not compatible with RFC 3986.
|
||
So now the `filename' slot stores the entire path and query components
|
||
and the `attributes' slot is always nil.
|
||
+++
|
||
*** New function `url-encode-url' for encoding a URI string.
|
||
The `url-retrieve' function now uses this to encode its URL argument,
|
||
in case that is not properly encoded.
|
||
|
||
---
|
||
** VHDL mode
|
||
|
||
*** The free software compiler GHDL is supported (and now the default).
|
||
|
||
*** Support for the VHDL-AMS packages has been added/updated.
|
||
|
||
*** Updated to the 2002 revision of the VHDL standard.
|
||
|
||
*** Accepts \r and \f as whitespace.
|
||
|
||
+++
|
||
** `which-func-modes' now defaults to t, so Which Function mode, when
|
||
enabled, applies to all applicable major modes.
|
||
|
||
---
|
||
** winner-mode-hook now runs when the mode is disabled, as well as when it is
|
||
enabled.
|
||
|
||
+++

** Obsolete packages:
|
||
+++
|
||
*** assoc.el
|
||
In most cases, assoc+member+push+delq work just as well.
|
||
And in any case it's just a terrible package: ugly semantics, terrible
|
||
inefficiency, and not namespace-clean.

* Incompatible Lisp Changes in Emacs 24.3
|
||
|
||
+++
|
||
** set-buffer-multibyte now signals an error in narrowed buffers.
|
||
|
||
+++
|
||
** (random) by default now returns a different random sequence in
|
||
every Emacs run. Use (random S), where S is a string, to set the
|
||
random seed to a value based on S, in order to get a repeatable
|
||
sequence in later calls.
|
||
|
||
---
|
||
** The function `x-select-font' can return a font spec, instead of a
|
||
font name as a string. Whether it returns a font spec or a font name
|
||
depends on the graphical library.
|
||
|
||
+++
|
||
** If the NEWTEXT arg to `replace-match' contains a substring "\?",
|
||
that substring is inserted literally even if the LITERAL arg is
|
||
non-nil, instead of causing an error to be signaled.
|
||
|
||
+++
|
||
** Docstrings starting with `*' no longer indicate user options.
|
||
Only variables defined using `defcustom' are considered user options.
|
||
The function `user-variable-p' is now an obsolete alias for
|
||
`custom-variable-p'.
|
||
|
||
+++
|
||
** The return values of `defalias', `defun' and `defmacro' have changed,
|
||
and are now undefined. For backwards compatibility, `defun' and
|
||
`defmacro' currently return the name of the newly defined
|
||
function/macro, but this should not be relied upon.
|
||
|
||
---
|
||
** `face-spec-set' no longer sets frame-specific attributes when the
|
||
third argument is a frame (that usage was obsolete since Emacs 22.2).
|
||
|
||
+++
|
||
** The arguments of `dbus-register-signal' are no longer just strings,
|
||
but keywords or keyword-string pairs. The old argument list will
|
||
still be supported for Emacs 24.x.
|
||
|
||
+++
|
||
** The CL package's `get-setf-method' function no longer exists.
|
||
Generalized variables are now part of core Emacs Lisp, and implemented
|
||
differently to the way cl.el used to do it. It is not possible to
|
||
define a compatible replacement for `get-setf-method'. See the file
|
||
gv.el for internal details of the new implementation.
|
||
|
||
** Spelling changes.
|
||
Some Lisp symbols have been renamed to avoid problems with spelling
|
||
that is incorrect or inconsistent with how Emacs normally spells a word.
|
||
|
||
---
|
||
*** Renamed functions
|
||
|

* Lisp changes in Emacs 24.3
|
||
|
||
** New sampling-based Elisp profiler.
|
||
Try M-x profiler-start, do some work, and then call M-x profiler-report.
|
||
When finished, use M-x profiler-stop. The sampling rate can be based on
|
||
CPU time or memory allocations.
|
||
|
||
+++
|
||
** CL-style generalized variables are now in core Elisp.
|
||
`setf' is autoloaded; `push' and `pop' accept generalized variables.
|
||
You can define your own generalized variables using `gv-define-simple-setter',
|
||
`gv-define-setter', etc.
|
||
|
||
+++
|
||
** `defun' also accepts a (declare DECLS) form, like `defmacro'.
|
||
The interpretation of the DECLS is determined by `defun-declarations-alist'.
|
||
|
||
** Minibuffer
|
||
+++
|
||
*** `read-regexp' has a new argument HISTORY; the first argument PROMPT
|
||
of `read-regexp' accepts a string ending with a colon and space, and its
|
||
second argument DEFAULTS can be a list of strings accessible via M-n
|
||
in the minibuffer ahead of other hard-coded useful regexp-related values.
|
||
More commands use `read-regexp' now to read their regexp arguments.
|
||
|
||
** Completion
|
||
|
||
*** New function `completion-table-with-quoting' to handle completion
|
||
in the presence of quoting, such as file completion in shell buffers.
|
||
|
||
+++
|
||
*** New function `completion-table-subvert' to use an existing completion
|
||
table, but with a different prefix.
|
||
|
||
** Debugger changes
|
||
|
||
+++
|
||
*** New error type and new function `user-error'.
|
||
These do not trigger the debugger.
|
||
|
||
+++
|
||
*** New option `debugger-bury-or-kill', saying what to do with the
|
||
debugger buffer when exiting debug.
|
||
|
||
+++
|
||
*** Set `debug-on-message' to enter the debugger when a certain
|
||
message is displayed in the echo area. This can be useful when trying
|
||
to work out which code is doing something.
|
||
---
|
||
*** New var `inhibit-debugger', automatically set to prevent accidental
|
||
recursive invocations.
|
||
|
||
** Window changes
|
||
+++
|
||
*** The functions get-lru-window, get-mru-window and get-largest-window
|
||
now accept a third argument to avoid choosing the selected window.
|
||
+++
|
||
*** Additional values recognized for option `window-combination-limit'.
|
||
|
||
+++
|
||
*** New macro `with-temp-buffer-window', similar to
|
||
`with-output-to-temp-buffer'.
|
||
|
||
---
|
||
*** `temp-buffer-resize-mode' no longer resizes windows that have been
|
||
reused.
|
||
|
||
+++
|
||
*** New command `fit-frame-to-buffer' adjusts the frame height to
|
||
fit the contents.
|
||
|
||
+++
|
||
*** The command `fit-window-to-buffer' can adjust the frame height
|
||
if the new option `fit-frame-to-buffer' is non-nil.
|
||
|
||
+++
|
||
*** New option switch-to-buffer-preserve-window-point to restore a
|
||
window's point when switching buffers.
|
||
+++
|
||
*** New display action functions `display-buffer-below-selected',
|
||
and `display-buffer-in-previous-window'.
|
||
+++
|
||
*** New display action alist entry `inhibit-switch-frame', if non-nil,
|
||
tells display action functions to avoid changing which frame is
|
||
selected.
|
||
+++
|
||
*** New display action alist entry `pop-up-frame-parameters', if
|
||
non-nil, specifies frame parameters to give any newly-created frame.
|
||
+++
|
||
*** New display action alist entry `previous-window', if non-nil,
|
||
specifies window to reuse in `display-buffer-in-previous-window'.
|
||
+++
|
||
*** New display action alist entries `window-height' and `window-width'
|
||
to specify size of new window created by `display-buffer'.
|
||
|
||
*** The following variables are obsolete, as they can be replaced by
|
||
appropriate entries in the `display-buffer-alist' function introduced
|
||
in Emacs 24.1:

** Time
|
||
---
|
||
*** `current-time-string' no longer requires that its argument's year
|
||
must be in the range 1000..9999. It now works with any year supported
|
||
by the underlying C implementation.
|
||
+++
|
||
*** `current-time' now returns extended-format time stamps
|
||
(HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds.
|
||
PSEC is typically a multiple of 1000 on current machines. Other
|
||
functions that use this format, such as file-attributes and
|
||
format-time-string, have been changed accordingly. Old-format time
|
||
stamps are still accepted.
|
||
---
|
||
*** The format of timers in timer-list and timer-idle-list is now
|
||
[TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS].
|
||
The PSECS slot is new, and uses picosecond resolution. It can be
|
||
accessed via the new timer--psecs accessor.
|
||
+++
|
||
*** Last-modified time stamps in undo lists now are of the form
|
||
(t HI-SECS LO-SECS USECS PSECS) instead of (t HI-SECS . LO-SECS).
|
||
|
||
+++
|
||
** Floating point functions now always return special values like NaN,
|
||
instead of signaling errors, if given invalid args, e.g. (log -1.0).
|
||
Previously, they returned NaNs on some platforms but signaled errors
|
||
on others. The affected functions are acos, asin, tan, exp, expt,
|
||
log, log10, sqrt, and mod.
|
||
|
||
+++
|
||
** Emacs tries to macroexpand interpreted (non-compiled) files during load.
|
||
This can significantly speed up execution of non-byte-compiled code,
|
||
but can also bump into previously unnoticed cyclic dependencies.
|
||
These are generally harmless: they will simply cause the macro calls
|
||
to be left for later expansion (as before), but will result in a
|
||
warning ("Eager macro-expansion skipped due to cycle") describing the cycle.
|
||
You may wish to restructure your code so this does not happen.
|
||
|
||
** Miscellaneous new functions:
|
||
+++
|
||
*** `autoloadp' tests if its argument is an autoloaded object.
|
||
+++
|
||
*** `autoload-do-load' performs the autoloading operation.
|
||
+++
|
||
*** `buffer-narrowed-p' tests if the buffer is narrowed.
|
||
+++
|
||
*** `file-name-base' returns a file name sans directory and extension.
|
||
+++
|
||
*** `function-get' fetches a function property, following aliases.
|
||
+++
|
||
*** `posnp' tests if an object is a `posn'.
|
||
+++
|
||
*** `set-temporary-overlay-map' sets up a temporary keymap that
|
||
takes precedence over most other maps for a short while (normally one key).
|
||
+++
|
||
*** `system-users' returns the user names on the system.
|
||
+++
|
||
*** `system-groups' returns the group names on the system.
|
||
+++
|
||
*** `tty-top-frame' returns the topmost frame of a text terminal.
|
||
|
||
+++
|
||
** New macros `setq-local' and `defvar-local'.
|
||
|
||
** Changes to special forms and macros
|
||
+++
|
||
*** `defun' and `defmacro' are now macros rather than special forms
|
||
+++
|
||
*** `kbd' is now a function rather than a macro.
|
||
|
||
+++
|
||
** New fringe bitmap `exclamation-mark'.
|
||
|
||
+++
|
||
** Face underlining can now use a wave.
|
||
|
||
** The following functions and variables are obsolete:
|
||
---
|
||
*** `automount-dir-prefix' (use `directory-abbrev-alist')
|
||
+++
|
||
*** `buffer-has-markers-at'
|
||
---
|
||
*** `macro-declaration-function' (use `macro-declarations-alist')
|
||
---
|
||
*** `window-system-version' (provides no useful information)
|
||
---
|
||
*** `dired-pop-to-buffer' (use `dired-mark-pop-up')
|
||
---
|
||
*** `query-replace-interactive'
|
||
---
|
||
*** `font-list-limit' (has had no effect since Emacs < 23)
|
||
|
||
|
||
* Changes in Emacs 24.3 on non-free operating systems
|
||
|
||
---
|
||
** Cygwin builds can use the native MS Windows user interface.
|
||
Pass --with-w32 to configure. The default remains the X11 interface.
|
||
|
||
** Two new functions are available in Cygwin builds:
|
||
`cygwin-convert-file-name-from-windows' and
|
||
`cygwin-convert-file-name-to-windows'. These functions allow Lisp
|
||
code to access the Cygwin file-name mapping machinery to convert
|
||
between Cygwin and Windows-native file and directory names.
|
||
|
||
** When invoked with the -nw switch to run on the Windows text-mode terminal,
|
||
Emacs now supports mouse highlight, help-echo (in the echo area), and
|
||
`mouse-autoselect-window'.
|
||
|
||
+++
|
||
** On MS Windows Vista and later Emacs now supports symbolic links.
|
||
|
||
+++
|
||
** On MS Windows, you can pass --without-libxml2 to configure.bat to omit
|
||
support for libxml2, even if its presence is detected.
|
||
|
||
---
|
||
** On Mac OS X, the Nextstep port requires OS X 10.4 or later.
|
||
|
||
---
|
||
** On Mac OS X, configure no longer automatically adds the Fink /sw
|
||
directories to the search path. You must add them yourself if you want them.
|
||
|
||
|
||
* Changes in Emacs 24.2
|
||
|
||
** This is mainly a bug-fix release.
|
||
|
||
|
||
* Installation Changes in Emacs 24.1
|
||
|
||
** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
|
||
to configure. Note that other libraries used by Emacs, RSVG and GConf,
|
||
also depend on Gtk+. You can disable them with --without-rsvg and
|
||
--without-gconf.
|
||
|
||
** Emacs can be compiled with GnuTLS support.
|
||
This happens by default if a suitably recent version of the library is
|
||
found at build time. To prevent this, use the configure option
|
||
`--without-gnutls'. See below for GnuTLS features.
|
||
|
||
** Emacs can be compiled with SELinux support.
|
||
This happens by default if a suitably recent version of the library is
|
||
found at build time. To prevent this, use the configure option
|
||
`--without-selinux'. See below for SELinux features.
|
||
|
||
** Emacs can be compiled with ImageMagick support.
|
||
This happens by default if a suitably recent version of the library is
|
||
found at build time. To prevent this, use the configure option
|
||
`--without-imagemagick'. See below for ImageMagick features.
|
||
This feature is not available for the Nextstep or MS ports.
|
||
|
||
** Emacs can be compiled with libxml2 support.
|
||
This happens by default if a suitably recent version of the library is
|
||
found at build time. To prevent this, use the configure option
|
||
`--without-xml2'. See below for libxml2 features.
|
||
|
||
** By default, the installed Info and man pages are compressed.
|
||
You can disable this by configuring --without-compress-info.
|
||
|
||
** New configure option --with-wide-int.
|
||
With it, Emacs integers typically have 62 bits, even on 32-bit machines.
|
||
On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB
|
||
to about 2 GiB.
|
||
|
||
** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost.
|
||
These provide no new functionality, they just remove the need to edit
|
||
lib-src/Makefile by hand in order to use the associated features.
|
||
|
||
** New configure option --enable-use-lisp-union-type.
|
||
This is only useful for Emacs developers to debug certain types of bugs.
|
||
This is not a new feature; only the configure flag is new.
|
||
|
||
** The standalone programs digest-doc and sorted-doc are removed.
|
||
Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'.
|
||
|
||
** The standalone program `fakemail' is removed.
|
||
If you need it, feedmail.el provides a superset of the functionality.
|
||
|
||
|
||
* Startup Changes in Emacs 24.1
|
||
|
||
** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
|
||
command line arguments, and the EMACS_UNIBYTE environment variable, no
|
||
longer have any effect. (They were declared obsolete in Emacs 23.)
|
||
|
||
** New command line option `--no-site-lisp' removes site-lisp directories
|
||
from load-path. -Q now implies this. This option does not affect the
|
||
EMACSLOADPATH environment variable (and hence has no effect for
|
||
Nextstep builds).
|
||
|
||
|
||
* Changes in Emacs 24.1
|
||
|
||
** Completion
|
||
|
||
*** Many packages now use the `completion-at-point' command,
|
||
rather than implementing separate completion commands.
|
||
|
||
*** `completion-at-point' now handles tags and semantic completion.
|
||
|
||
*** Completion in a non-minibuffer now tries to detect the end of completion
|
||
and pops down the *Completions* buffer accordingly.
|
||
|
||
*** New option `completion-cycle-threshold' allows completion cycling.
|
||
|
||
*** New option `completion-category-overrides' for overriding the
|
||
default completion style in certain circumstances.
|
||
|
||
*** New completion style `substring'.
|
||
|
||
*** Completion of buffer names uses `substring' completion by default.
|
||
|
||
*** The option `widget-complete-field' has been removed.
|
||
|
||
** Mail changes
|
||
|
||
*** The first time you try sending mail, Emacs asks for a mail method.
|
||
This is implemented by a new default for `send-mail-function', which
|
||
is `sendmail-query-once'. This offers to use the smtpmail package, or
|
||
to use the old defaults relying on external mail facilities
|
||
(`sendmail-send-it' on GNU/Linux and other Unix-like systems, and
|
||
`mailclient-send-it' on Windows).
|
||
|
||
*** Typing C-c m in the buffer made by M-x report-emacs-bug transfers
|
||
the report to your desktop's preferred mail client, if there is one.
|
||
This uses either the "xdg-email" utility, or Mac OS's "open" command.
|
||
|
||
*** See Changes in Specialized Modes and Packages for SMTPmail changes
|
||
and Mail mode changes
|
||
|
||
** Emacs server and client changes
|
||
|
||
*** New option `server-port' specifies the port for TCP Emacs servers.
|
||
|
||
*** New emacsclient argument -q/--quiet suppresses some status messages.
|
||
|
||
*** New emacsclient argument --frame-parameters specifies the frame
|
||
parameters of any newly-created graphical frame.
|
||
|
||
*** If emacsclient shuts down due to Emacs signaling an error,
|
||
its exit status is 1.
|
||
|
||
*** New emacsclient argument --parent-id ID.
|
||
This opens a client frame in parent X window ID, via XEmbed, similar
|
||
to the --parent-id argument to Emacs.
|
||
|
||
** Internationalization changes
|
||
|
||
*** Emacs now supports display and editing of bidirectional text.
|
||
Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are
|
||
displayed in the correct visual order as expected by users of those
|
||
scripts. The display reordering is a "full bidirectionality" class
|
||
implementation of the Unicode Bidirectional Algorithm (UBA). Buffers
|
||
with no RTL text should look exactly the same as before.
|
||
|
||
**** New buffer-local variable `bidi-display-reordering'.
|
||
To disable display reordering in a buffer, change this to nil.
|
||
|
||
**** New buffer-local variable `bidi-paragraph-direction'.
|
||
If nil (the default), Emacs determines the base direction of each
|
||
paragraph from its text, as specified by the UBA. Setting the value
|
||
to `right-to-left' or `left-to-right' forces a base direction on each
|
||
paragraph.
|
||
|
||
Paragraphs with right-to-left base direction are displayed starting at
|
||
the right window edge.
|
||
|
||
*** Enhanced support for characters with no glyphs in available fonts,
|
||
or, on text terminals, characters that cannot be encoded by the
|
||
terminal coding system. The new option `glyphless-char-display-control'
|
||
specifies how to display them: as a hexadecimal code in a box, a thin
|
||
1-pixel space, an empty box, etc.
|
||
|
||
*** New input methods for Farsi and Bulgarian
|
||
(farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic).
|
||
|
||
*** `nobreak-char-display' now also highlights Unicode hyphen chars
|
||
(U+2010 and U+2011).
|
||
|
||
*** New Hebrew translation of the Emacs Tutorial.
|
||
Type `C-u C-h t' to choose it in case your language setup doesn't
|
||
automatically select it.
|
||
|
||
** An Emacs Lisp package manager is now included.
|
||
This is a convenient way to download and install additional packages,
|
||
from a package repository at http://elpa.gnu.org.
|
||
|
||
*** M-x list-packages shows a list of packages, which can be
|
||
selected for installation.
|
||
|
||
*** New command `describe-package', bound to `C-h P'.
|
||
|
||
*** By default, all installed packages are loaded automatically when
|
||
Emacs starts up. To disable this, set `package-enable-at-startup' to
|
||
nil. To specify the packages to load, customize `package-load-list'.
|
||
|
||
** Custom theme changes
|
||
|
||
*** New command `M-x customize-themes', which provides a convenient
|
||
interface for enabling and disabling Custom themes.
|
||
|
||
*** New option `custom-theme-load-path' is the load path for themes.
|
||
Emacs no longer looks for Custom themes in `load-path'. The default
|
||
value of `custom-theme-load-path' says to look for themes in
|
||
`custom-theme-directory', followed by a subdirectory of
|
||
`data-directory' named "themes/", which contains a small selection of
|
||
built-in Custom themes.
|
||
|
||
*** New option `custom-safe-themes' records known-safe theme files.
|
||
If a theme is not in this list, Emacs queries before loading it, and
|
||
offers to save the theme to `custom-safe-themes' automatically. By
|
||
default, all themes included in Emacs are treated as safe.
|
||
|
||
** Improved GTK integration
|
||
|
||
*** GTK scroll-bars are now placed on the right by default.
|
||
The function `set-scroll-bar-mode' can change this.
|
||
|
||
*** GTK tool bars can have just text, just images or images and text.
|
||
Customize `tool-bar-style' to choose the style. On a Gnome desktop,
|
||
the default is taken from desktop settings.
|
||
|
||
*** GTK tool bars can be placed on any edge of the frame.
|
||
The frame-parameter tool-bar-position controls this. It takes the
|
||
values top, left, right or bottom. The Options => Show/Hide menu has
|
||
entries for this.
|
||
|
||
*** The default colors for selected text (the `region' face) are taken
|
||
from the GTK theme when Emacs is built with GTK.
|
||
|
||
*** Emacs uses GTK tooltips by default if built with GTK.
|
||
You can disable this by changing `x-gtk-use-system-tooltips' to nil.
|
||
|
||
** Graphical interface changes
|
||
|
||
*** On graphical displays, the mode-line no longer ends in dashes.
|
||
Also, the first dash (which does not indicate anything) is just
|
||
displayed as a space.
|
||
|
||
*** `menu-bar-select-buffer-function' lets you choose another operation
|
||
instead of `switch-to-buffer' when selecting an item in the Buffers menu.
|
||
|
||
*** Lucid menus and dialogs can display antialiased fonts if Emacs is
|
||
built with Xft. These fonts can be set via X resources, for example:
|
||
Emacs.pane.menubar.font: Courier-12
|
||
|
||
** Exiting changes
|
||
|
||
*** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP,
|
||
or if it receives a SIGINT signal in batch mode.
|
||
|
||
*** `kill-emacs-hook' is now also run in batch mode.
|
||
Third-party code which adds to `kill-emacs-hook' should check if they
|
||
do the right thing in batch mode.
|
||
|
||
** Scrolling changes
|
||
|
||
*** New scrolling commands `scroll-up-command' and `scroll-down-command'
|
||
(bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom
|
||
of buffer at first key-press (instead they move to top/bottom of buffer)
|
||
when `scroll-error-top-bottom' is non-nil.
|
||
|
||
*** New option `scroll-error-top-bottom' (see above).
|
||
|
||
*** New scrolling commands `scroll-up-line' and `scroll-down-line'
|
||
scroll a line instead of full screen.
|
||
|
||
*** New property `scroll-command' should be set on a command's symbol to
|
||
define it as a scroll command affected by `scroll-preserve-screen-position'.
|
||
|
||
*** If you customize `scroll-conservatively' to a value greater than 100,
|
||
Emacs will never recenter point in the window when it scrolls due to
|
||
cursor motion commands or commands that move point (e.f., `M-g M-g').
|
||
Previously, you needed to use `most-positive-fixnum' as the value of
|
||
`scroll-conservatively' to achieve the same effect.
|
||
|
||
*** "Aggressive" scrolling now honors the scroll margins.
|
||
If you customize `scroll-up-aggressively' or
|
||
`scroll-down-aggressively' and move point off the window, Emacs now
|
||
scrolls the window so as to avoid positioning point inside the scroll
|
||
margin.
|
||
|
||
** Basic SELinux support has been added.
|
||
This requires Emacs to be linked with libselinux at build time.
|
||
|
||
*** Emacs preserves the SELinux file context when backing up.
|
||
Also, the function `copy-file' has an extra optional argument for
|
||
preserving SELinux context, and the return value of `backup-buffer'
|
||
now includes the SELinux context.
|
||
|
||
*** New functions `file-selinux-context' and `set-file-selinux-context'
|
||
get and set the SELinux context of a file.
|
||
|
||
** Trash changes
|
||
|
||
*** `delete-by-moving-to-trash' now only affects commands that specify
|
||
trashing. This avoids inadvertently trashing temporary files.
|
||
|
||
*** Calling `delete-file' or `delete-directory' with a prefix argument
|
||
now forces true deletion, regardless of `delete-by-moving-to-trash'.
|
||
|
||
** File- and directory-local variable changes
|
||
|
||
*** You can stop directory local vars from applying to subdirectories.
|
||
Add an element (subdirs . nil) to the alist portion of any variables
|
||
settings to indicate that the section should not apply to
|
||
subdirectories.
|
||
|
||
*** Directory local variables can apply to some file-less buffers.
|
||
Affected modes include dired, vc-dir, and log-edit. For example,
|
||
adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will
|
||
turn on `whitespace-mode' for *vc-diff* buffers. Modes should call
|
||
`hack-dir-local-variables-non-file-buffer' to support this.
|
||
|
||
*** Using "mode: MINOR-MODE" to enable a minor mode is deprecated.
|
||
Instead, use "eval: (minor-mode 1)".
|
||
|
||
*** The variable `inhibit-first-line-modes-regexps' has been renamed
|
||
to `inhibit-local-variables-regexps'. As the name suggests, it now
|
||
applies to ALL file local variables, not just -*- lines. The
|
||
associated `inhibit-first-line-modes-suffixes' has been renamed in the
|
||
corresponding way.
|
||
|
||
** Window changes
|
||
|
||
*** The `quit-window' command now restores the last buffer displayed
|
||
in the quitted window.
|
||
|
||
*** Resizing an Emacs frame now preserves proportional window sizes,
|
||
modulo restrictions like window minimum sizes and fixed-size windows.
|
||
|
||
*** The behavior of `display-buffer' is now customizable in detail.
|
||
|
||
**** New option `display-buffer-base-action' specifies a list of
|
||
user-determined display "actions" (functions and optional arguments
|
||
for choosing the displaying window).
|
||
|
||
This takes precedence over the default display action, which is
|
||
specified by `display-buffer-fallback-action'.
|
||
|
||
**** New option `display-buffer-alist' maps buffer name regexps to
|
||
display actions, taking precedence over `display-buffer-base-action'.
|
||
|
||
*** New option `window-combination-limit'.
|
||
The new option `window-combination-limit' allows to return the space
|
||
obtained for resizing or creating a window more reliably to the window
|
||
from which such space was obtained.
|
||
|
||
*** New option `window-combination-resize'.
|
||
The new option `window-combination-resize' allows to split a window that
|
||
otherwise cannot be split because it's too small by stealing space from
|
||
other windows in the same combination. Subsequent resizing or deletion
|
||
of the window will resize all windows in the same combination as well.
|
||
|
||
*** New option `frame-auto-hide-function' lets you choose between
|
||
iconifying or deleting a frame when burying a buffer in a dedicated
|
||
frame, or quitting a window showing a buffer in a frame of its own.
|
||
|
||
*** New commands `maximize-window' and `minimize-window'.
|
||
These maximize and minimize the size of a window within its frame.
|
||
|
||
*** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'.
|
||
These functions allow to navigate through the live buffers that have
|
||
been shown in a specific window.
|
||
|
||
** Minibuffer changes
|
||
|
||
*** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'.
|
||
This is handy for minibuffer-only frames, and is also used for the feature
|
||
where mouse-1 pops up *Messages*"', which can now easily be changed.
|
||
|
||
*** Minibuffers set `truncate-lines' to nil.
|
||
If you want to change the value to something else, you could use
|
||
for example `minibuffer-setup-hook'.
|
||
|
||
** `auto-mode-case-fold' is now enabled by default.
|
||
|
||
** `backup-by-copying-when-mismatch' now defaults to t.
|
||
|
||
** New basic faces `error', `warning', `success'.
|
||
These are used to highlight text indicating failure, caution or
|
||
successful operation.
|
||
|
||
** New option `list-colors-sort' defines the color sort order
|
||
for `list-colors-display'.
|
||
|
||
** The variable `focus-follows-mouse' now always defaults to nil.
|
||
|
||
|
||
* Editing Changes in Emacs 24.1
|
||
|
||
** Search changes
|
||
|
||
*** C-y in Isearch is now bound to `isearch-yank-kill', instead of
|
||
`isearch-yank-line'.
|
||
|
||
*** M-y in Isearch is now bound to `isearch-yank-pop', instead of
|
||
`isearch-yank-kill'.
|
||
|
||
*** M-s C-e in Isearch is now bound to `isearch-yank-line'.
|
||
|
||
** New commands `count-words-region' and `count-words'.
|
||
|
||
*** M-= is bound to `count-words-region', not `count-lines-region'.
|
||
The `count-words-region' command, when called interactively, reports
|
||
the number of lines, words, and characters in the region. It is a
|
||
superset of the old `count-lines-region', which is now an obsolete
|
||
alias for it.
|
||
|
||
** The command `just-one-space' (M-SPC), if given a negative argument,
|
||
also deletes newlines around point.
|
||
|
||
** Deletion changes
|
||
|
||
*** New option `delete-active-region'.
|
||
If non-nil, [delete] and DEL delete the region if it is active and no
|
||
prefix argument is given. If set to `kill', those commands kill
|
||
instead.
|
||
|
||
*** New command `delete-forward-char', bound to [delete].
|
||
This is meant for interactive use, and obeys `delete-active-region'.
|
||
The command `delete-char' does not obey `delete-active-region'.
|
||
|
||
*** `delete-backward-char' is now a Lisp function.
|
||
Apart from obeying `delete-active-region', its behavior is unchanged.
|
||
However, the byte compiler now warns if it is called from Lisp; Lisp
|
||
callers should use delete-char with a negative argument instead.
|
||
|
||
*** The option `mouse-region-delete-keys' has been deleted.
|
||
|
||
** Selection changes.
|
||
|
||
The default handling of clipboard and primary selections has been
|
||
changed to conform with modern X applications. In short, most
|
||
commands for killing and yanking text now use the clipboard, while
|
||
mouse commands use the primary selection.
|
||
|
||
In the following, we provide a list of these changes, followed by a
|
||
list of steps to get the old behavior back if you prefer that.
|
||
|
||
*** `select-active-regions' now defaults to t.
|
||
Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
|
||
the kill ring. The selected text is put in the primary selection, if
|
||
the system possesses a separate primary selection facility (e.g. X).
|
||
|
||
**** `select-active-regions' also accepts a new value, `only'.
|
||
This means to only set the primary selection for temporarily active
|
||
regions (usually made by mouse-dragging or shift-selection);
|
||
"ordinary" active regions, such as those made with C-SPC followed by
|
||
point motion, do not alter the primary selection.
|
||
|
||
**** `mouse-drag-copy-region' now defaults to nil.
|
||
|
||
*** mouse-2 is now bound to `mouse-yank-primary'.
|
||
This pastes from the primary selection, ignoring the kill-ring.
|
||
Previously, mouse-2 was bound to `mouse-yank-at-click'.
|
||
|
||
*** `x-select-enable-clipboard' now defaults to t on all platforms.
|
||
|
||
*** `x-select-enable-primary' now defaults to nil.
|
||
Thus, commands that kill text or copy it to the kill-ring (such as
|
||
M-w, C-w, and C-k) also use the clipboard---not the primary selection.
|
||
|
||
**** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
|
||
exactly equivalent to M-w, C-w, and C-y respectively.
|
||
|
||
**** Note that on MS-Windows, `x-select-enable-clipboard' was already
|
||
non-nil by default, as Windows does not support the primary selection
|
||
between applications.
|
||
|
||
*** To return to the previous behavior, do the following:
|
||
|
||
**** Change `select-active-regions' to nil.
|
||
**** Change `mouse-drag-copy-region' to t.
|
||
**** Change `x-select-enable-primary' to t (on X only).
|
||
**** Change `x-select-enable-clipboard' to nil.
|
||
**** Bind `mouse-yank-at-click' to mouse-2.
|
||
|
||
*** Support for X cut buffers has been removed.
|
||
|
||
*** X clipboard managers are now supported.
|
||
To inhibit this, change `x-select-enable-clipboard-manager' to nil.
|
||
|
||
** New command `C-x r N' (`rectangle-number-lines') numbers the lines
|
||
in the current rectangle. With a prefix argument, this prompts for a
|
||
number to count from and for a format string.
|
||
|
||
** `redisplay-dont-pause' now defaults to t.
|
||
This makes Emacs feel more responsive to editing commands that arrive
|
||
at high rate, e.g. if you lean on some key, because stopping redisplay
|
||
in the middle (when this variable is nil) forces more expensive
|
||
updates later on, and Emacs appears to be unable to keep up.
|
||
|
||
** The behavior of <TAB> for active regions in Text mode has changed.
|
||
In Text and related modes, typing <TAB> (`indent-for-tab-command')
|
||
when the region is active causes Emacs to indent all the lines in the
|
||
region, aligning them with the line previous to the first line in the
|
||
region (or with the left margin if there is no previous line).
|
||
|
||
** When `occur' is called with a prefix argument, matching strings are
|
||
collected into the `*Occur*' buffer without line numbers. If there
|
||
are parenthesized subexpressions in the specified regexp, `occur'
|
||
reads replacement text that may contain \\& and \\N whose convention
|
||
follows `replace-match'.
|
||
|
||
|
||
* Changes in Specialized Modes and Packages in Emacs 24.1
|
||
|
||
** Archive Mode has basic support for browsing and updating 7z archives.
|
||
|
||
** BibTeX mode
|
||
|
||
*** BibTeX mode now supports biblatex.
|
||
Use the variable `bibtex-dialect' to select different BibTeX dialects.
|
||
`bibtex-entry-field-alist' is now an obsolete alias for
|
||
`bibtex-BibTeX-entry-alist'.
|
||
|
||
*** New command `bibtex-search-entries', bound to C-c C-a.
|
||
|
||
*** New `bibtex-entry-format' option `sort-fields', disabled by default.
|
||
|
||
*** New variable `bibtex-search-entry-globally'.
|
||
|
||
** Browse-url
|
||
|
||
*** New option `browse-url-mailto-function' specifies how to handle "mailto:"s.
|
||
|
||
*** The default browser used by the package is now the "xdg-open" program,
|
||
on platforms that support it. This calls your desktop's preferred browser.
|
||
|
||
** Calendar, Diary, and Appt
|
||
|
||
*** Diary entries can contain non-printing "comments".
|
||
See the variable `diary-comment-start'.
|
||
|
||
*** Appointments can specify their individual warning times.
|
||
See the variable `appt-warning-time-regexp'.
|
||
|
||
*** The function specified by `appt-disp-window-function' may be passed
|
||
lists of arguments if multiple appointments are due at similar times.
|
||
If you are using a custom function for this, you should update it.
|
||
|
||
*** New function `diary-hebrew-birthday'.
|
||
|
||
*** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array'
|
||
may no longer be nil, but must all be strings.
|
||
|
||
*** The obsolete (since Emacs 22.1) method of enabling the appt
|
||
package by adding `appt-make-list' to `diary-hook' has been removed.
|
||
Use `appt-activate' instead.
|
||
|
||
*** Some appt variables (obsolete since Emacs 22.1) have been removed:
|
||
appt-issue-message (use the function appt-activate)
|
||
appt-visible/appt-msg-window (use the variable appt-display-format)
|
||
|
||
*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
|
||
view-diary-entries, list-diary-entries, show-all-diary-entries
|
||
|
||
** CC Mode
|
||
|
||
*** New feature to "guess" the style in an existing buffer.
|
||
The main entry point is M-x c-guess.
|
||
|
||
*** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang).
|
||
|
||
*** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes.
|
||
Thus C-M-a will, by default, go to the beginning of the immediate function,
|
||
not the top level.
|
||
|
||
*** "Macros with semicolons" can be registered for correct indentation.
|
||
Where such a macro ends a line (no semicolon) the next statement is no longer
|
||
parsed as a statement continuation.
|
||
|
||
** Comint and modes derived from it use the standard completion code.
|
||
|
||
** Compilation mode
|
||
|
||
*** Compilation mode can be used without Font Lock mode.
|
||
`compilation-parse-errors-function' is now obsolete.
|
||
|
||
*** New variable `compilation-filter-start', which is bound while
|
||
`compilation-filter-hook' runs. It records the start position of the
|
||
text inserted by `compilation-filter'.
|
||
|
||
*** `compilation-error-screen-columns' and `compilation-first-column'
|
||
are obeyed in the editing buffer. So programming language modes can
|
||
set them, whereas previously only the value in the *Compilation*
|
||
buffer was used.
|
||
|
||
** Customize
|
||
|
||
*** Customize buffers now contain a search field.
|
||
The search is performed using `customize-apropos'.
|
||
To turn off the search field, set `custom-search-field' to nil.
|
||
|
||
*** Options in customize group buffers start out hidden if not customized.
|
||
Use the arrow to the left of the option name to toggle visibility.
|
||
|
||
*** custom-buffer-sort-alphabetically now defaults to t.
|
||
|
||
*** The color widget now has a "Choose" button, which allows you to
|
||
choose a color via `list-colors-display'.
|
||
|
||
** D-Bus
|
||
|
||
*** It is now possible to access buses other than the default system
|
||
or session bus.
|
||
|
||
*** The `dbus-register-method' and `dbus-register-property' functions
|
||
optionally do not register names.
|
||
|
||
*** The new function `dbus-register-service' registers a known service
|
||
name on a D-Bus without also registering a property or a method.
|
||
|
||
** Dired-x
|
||
|
||
*** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'),
|
||
if called with a prefix argument, read a file name from the minibuffer
|
||
instead of using the current buffer.
|
||
|
||
*** The "dired local variables" feature of Dired-x is obsolete.
|
||
The standard directory local variables feature replaces it.
|
||
|
||
** ERC changes
|
||
|
||
*** New options `erc-autojoin-timing' and `erc-autojoin-delay',
|
||
controlling attempts to autojoin a channel.
|
||
|
||
*** New variable `erc-coding-system-precedence': If we use `undecided'
|
||
as the server coding system, this variable will then be consulted.
|
||
The default is to decode strings that can be decoded as utf-8 as
|
||
utf-8, and do the normal `undecided' decoding for the rest.
|
||
|
||
** Eshell changes
|
||
|
||
*** The default value of `eshell-directory-name' has changed
|
||
to be an "eshell" directory in `user-emacs-directory'.
|
||
The old "~/.eshell/" directory is still used if it exists, though.
|
||
|
||
** gdb-mi
|
||
|
||
*** The M-x gdb command now uses the GDB Machine Interface protocol.
|
||
It now supports multithread non-stop debugging and simultaneous
|
||
debugging of several threads.
|
||
|
||
** Image mode
|
||
|
||
*** RET (`image-toggle-animation') toggles animation, if applicable.
|
||
Animation plays once, unless the option `image-animate-loop' is non-nil.
|
||
|
||
** Info
|
||
|
||
*** New command M-x info-display-manual displays a named Info manual.
|
||
If that manual is already visited in some Info buffer, it displays
|
||
that buffer. (This is handy if you have many manuals in many *info*
|
||
buffers, and don't remember the name of the buffer visiting the manual
|
||
you want to consult.) Otherwise, it loads and displays the manual.
|
||
|
||
*** `e' is now bound to `end-of-buffer' rather than to `Info-edit'.
|
||
This is for compatibility with the stand-alone Info reader program,
|
||
and also because `Info-edit' is a rarely used command that is disabled
|
||
by default.
|
||
|
||
** Mail mode changes (not Message mode)
|
||
|
||
*** New command M-x mail-add-attachment for adding MIME attachments
|
||
|
||
*** The command M-x mail-attach-file was renamed to M-x mail-insert-file.
|
||
(Its name is misleading, since it has nothing to do with MIME
|
||
attachments.) The old name is now an obsolete alias to the new name.
|
||
|
||
** MH-E has been updated to MH-E version 8.3.1.
|
||
See MH-E-NEWS for details.
|
||
|
||
** Modula-2 mode provides auto-indentation.
|
||
|
||
** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
|
||
|
||
** nXML mode no longer binds C-RET to `nxml-complete'.
|
||
Completion is now performed via `completion-at-point', bound to C-M-i
|
||
or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the
|
||
default), this performs tag completion.
|
||
|
||
** Org mode has been updated to version 7.8.09.
|
||
See ORG-NEWS for details.
|
||
|
||
** Prolog mode has been completely revamped, with lots of additional
|
||
functionality such as more intelligent indentation, electricity,
|
||
support for more variants, including Mercury, and a lot more.
|
||
|
||
** Rmail
|
||
|
||
*** The command `rmail-epa-decrypt' decrypts OpenPGP data
|
||
in the Rmail incoming message.
|
||
|
||
*** The variable `rmail-message-filter' no longer has any effect.
|
||
This change was made in Emacs 23.1 but was not advertised at the time.
|
||
Try using `rmail-show-message-hook' instead.
|
||
|
||
** Shell mode
|
||
|
||
*** M-x shell prompts for the shell path name if the default directory
|
||
is a remote file name and neither the environment variable $ESHELL nor
|
||
the variable `explicit-shell-file-name' is set.
|
||
|
||
*** TAB is now bound to the standard `completion-at-point' command,
|
||
which now implements the pcomplete rules for shell command completion.
|
||
|
||
** SMTPmail
|
||
|
||
*** SMTPmail now uses encrypted connections (via STARTTLS) by default
|
||
if the mail server supports them. This uses either built-in GnuTLS
|
||
support, or the starttls.el library. Customize `smtpmail-stream-type'
|
||
to change this.
|
||
|
||
*** The variable `smtpmail-auth-credentials' has been removed.
|
||
By default, the information is now stored in the file ~/.authinfo.
|
||
This was the default value of smtpmail-auth-credentials. If you had
|
||
customized smtpmail-auth-credentials to a list of user names and
|
||
passwords, those settings are not used. During your first connection
|
||
to the smtp server, Emacs will prompt for the user name and password,
|
||
and offer to save them to ~/.authinfo. Or you can manually copy the
|
||
credentials to ~/.authinfo. For example, if you had
|
||
|
||
(setq smtpmail-auth-credentials
|
||
'(("mail.example.org" 25 "jim" "s!cret")))
|
||
|
||
then the equivalent line in ~/.authinfo would be
|
||
|
||
machine mail.example.org port 25 login jim password s!cret
|
||
|
||
See the auth-source manual for more information, e.g. on encrypting
|
||
the credentials file.
|
||
|
||
*** The variable `smtpmail-starttls-credentials' has been removed.
|
||
If you had that set, you need to put
|
||
|
||
machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert"
|
||
|
||
in your ~/.authinfo file instead.
|
||
|
||
*** SMTPmail defaults to using the address in the From: header as the
|
||
SMTP MAIL FROM envelope. To override this, set `mail-envelope-from'
|
||
to the address you wish to use instead.
|
||
|
||
** SQL mode
|
||
|
||
*** New options `sql-port', `sql-connection-alist', `sql-send-terminator',
|
||
and `sql-oracle-scan-on'.
|
||
|
||
*** New options controlling prompting for login parameters.
|
||
Each supported product has a custom variable `sql-*-login-params',
|
||
which is a list of the parameters to be prompted for before a
|
||
connection is established.
|
||
|
||
*** The command `sql-product-interactive' now takes a prefix argument,
|
||
which causes it to prompt for an SQL product.
|
||
|
||
*** Product-specific SQL interactive commands now take prefix arguments.
|
||
These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.),
|
||
given a prefix argument, prompt for a name for the SQL interactive
|
||
buffer. This reduces the need for calling `sql-rename-buffer'.
|
||
|
||
*** SQL interactive modes suppress command continuation prompts, and
|
||
replace tabs with spaces. The first change impacts multiple line SQL
|
||
statements entered with C-j between each line, statements yanked into
|
||
the buffer and statements sent with `sql-send-*' functions. The
|
||
second prevents the MySQL and Postgres interpreters from listing
|
||
object name completions when sent text via `sql-send-*' functions.
|
||
|
||
*** New command `sql-connect' starts a predefined SQLi session,
|
||
using the login parameters from `sql-connection-alist'.
|
||
|
||
*** New "Save Connection" menu item in SQLi buffers.
|
||
This gathers the login params specified for the SQLi session, if it
|
||
was not started by a connection, and saves them as a new connection.
|
||
|
||
*** New commands for listing database objects and details:
|
||
sql-list-all and sql-list-table.
|
||
|
||
*** An API for manipulating SQL product definitions has been added.
|
||
|
||
** TeX modes
|
||
|
||
*** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
|
||
|
||
** Tramp
|
||
|
||
*** New inline access method "ksu" (kerberized su).
|
||
|
||
*** The following access methods are discontinued: "ssh1_old",
|
||
"ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish".
|
||
|
||
*** The user option `remote-file-name-inhibit-cache' controls whether
|
||
remote file attributes are cached for better performance.
|
||
|
||
*** The option `ange-ftp-binary-file-name-regexp' has changed its
|
||
default value to "".
|
||
|
||
*** Handlers for `file-selinux-context' and `set-file-selinux-context'
|
||
for remote machines which support SELinux.
|
||
|
||
** New function `url-queue-retrieve', which behaves like url-retrieve,
|
||
but with limits (`url-queue-parallel-processes', `url-queue-timeout') on
|
||
the degree of parallelism.
|
||
|
||
** VC and related modes
|
||
|
||
*** Support for pulling on distributed version control systems.
|
||
The command C-x v + (`vc-pull') runs a "pull" operation, if it is
|
||
supported (currently with Bzr, Git, and Mercurial), to update the
|
||
current branch and working tree. A prefix argument means to prompt
|
||
the user for specifics, e.g. a pull location.
|
||
|
||
*** `vc-update' is now an alias for `vc-pull'.
|
||
|
||
*** Support for merging on distributed version control systems.
|
||
The command C-x v m (`vc-merge') now runs a "merge" operation, if it
|
||
is supported (currently with Bzr, Git, and Mercurial), to merge
|
||
changes from another branch into the current one. It prompts for
|
||
specifics, e.g. a merge source.
|
||
|
||
*** New option `vc-revert-show-diff' controls whether `vc-revert'
|
||
shows a diff while querying the user. It defaults to t.
|
||
|
||
*** Log entries in some Log View buffers can be toggled to display a
|
||
longer description by typing RET (log-view-toggle-entry-display).
|
||
This is currently supported for Bzr, Git, and Mercurial (to support
|
||
another backend, define a `log-view-expanded-log-entry-function').
|
||
In the Log View buffers made by C-x v L (`vc-print-root-log'), you can
|
||
use this to display the full log entry for the revision at point.
|
||
|
||
*** New command `vc-ediff' allows visual comparison of two revisions
|
||
of a file similar to `vc-diff', but using ediff backend.
|
||
|
||
*** The option `vc-initial-comment' was removed in Emacs 23.2, but
|
||
this was not advertised at the time.
|
||
|
||
*** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'.
|
||
Since Emacs 23, it has done the same thing as `toggle-read-only', but
|
||
this was not advertised at the time.
|
||
|
||
** Obsolete modes
|
||
|
||
*** abbrevlist.el
|
||
|
||
*** erc-hecomplete.el (use erc-pcomplete.el instead)
|
||
|
||
*** partial-completion-mode (complete.el) is obsolete.
|
||
You can get a comparable behavior with:
|
||
(setq completion-styles '(partial-completion initials))
|
||
(setq completion-pcm-complete-word-inserts-delimiters t)
|
||
|
||
*** pc-mode.el is obsolete (CUA mode is much more comprehensive).
|
||
|
||
*** pgg is obsolete (use EasyPG instead).
|
||
|
||
*** sregex.el is obsolete, since rx.el is a strict superset.
|
||
|
||
*** s-region.el and pc-select.el are obsolete.
|
||
They are superseded by shift-select-mode, enabled by default since 23.1.
|
||
|
||
*** vc-mcvs.el is obsolete (for lack of a maintainer).
|
||
|
||
** Miscellaneous
|
||
|
||
*** The Landmark game is now invoked with `landmark', not `lm'.
|
||
Its functions and variables have been similarly renamed.
|
||
|
||
*** In `ido-file-completion-map', C-v is no longer bound to `ido-toggle-vc'.
|
||
(This interfered with cua-mode.)
|
||
|
||
*** f90.el has some support for Fortran 2008 syntax.
|
||
|
||
*** `copyright-fix-years' can optionally convert consecutive years to ranges.
|
||
|
||
*** New command `nato-region' converts text to NATO phonetic alphabet.
|
||
|
||
|
||
* New Modes and Packages in Emacs 24.1
|
||
|
||
** Occur Edit mode applies edits made in *Occur* buffers to the
|
||
original buffers. It is bound to "e" in Occur mode.
|
||
|
||
** New global minor mode electric-pair-mode.
|
||
When enabled, typing an open parenthesis automatically inserts the
|
||
matching closing one.
|
||
|
||
** New global minor mode electric-indent-mode.
|
||
When enabled, typing certain characters triggers reindentation.
|
||
Major modes wishing to use this can set electric-indent-chars or
|
||
electric-indent-functions.
|
||
|
||
** New global minor mode electric-layout-mode.
|
||
When enabled, typing certain characters automatically inserts newlines.
|
||
Major modes wishing to use this can set electric-layout-rules.
|
||
|
||
** tabulated-list.el provides a generic major mode for tabulated data,
|
||
from which other modes can be derived.
|
||
|
||
** pcase.el provides the ML-style pattern matching macro `pcase'.
|
||
|
||
** secrets.el is an implementation of the Secret Service API, an
|
||
interface to password managers like GNOME Keyring or KDE Wallet. The
|
||
Secret Service API requires D-Bus for communication. The command
|
||
`secrets-show-secrets' offers a buffer with a visualization of the
|
||
secrets.
|
||
|
||
** notifications.el provides an implementation of the Desktop
|
||
Notifications API. It requires D-Bus for communication.
|
||
|
||
** soap-client.el supports access to SOAP web services from Emacs.
|
||
soap-inspect.el is an interactive inspector for SOAP WSDL structures.
|
||
|
||
** New generic mode, xmodmap-generic-mode, for xmodmap files.
|
||
|
||
** New emacs-lock.el package.
|
||
The previous version has been moved to obsolete/old-emacs-lock.el.
|
||
Now, there is a proper minor mode `emacs-lock-mode'. Protection
|
||
against exiting Emacs and killing the buffer can be set separately.
|
||
The mechanism for automatically turning off protection for buffers
|
||
with dead inferior processes has been generalized.
|
||
|
||
|
||
* Incompatible Lisp Changes in Emacs 24.1
|
||
|
||
** Passing a nil argument to a minor mode function call now ENABLES
|
||
the minor mode unconditionally. This is so that you can write e.g.
|
||
|
||
(add-hook 'text-mode-hook 'foo-mode)
|
||
|
||
to enable foo-mode in Text mode buffers, removing the need for
|
||
`turn-on-foo-mode' style functions. This affects all mode commands
|
||
defined by `define-minor-mode'. If called interactively, the mode
|
||
command still toggles the minor mode.
|
||
|
||
** The return value of `backup-buffer' has changed.
|
||
It is now a list of three elements, where the second element is a list
|
||
describing the original file's SELinux context. If Emacs or the
|
||
system lacks SELinux support, the context list is (nil nil nil nil).
|
||
See "Basic SELinux support" above, under "Changes in Emacs 24.1".
|
||
|
||
** `char-direction-table' and the `char-direction' function were deleted.
|
||
They were buggy and inferior to the new support of bidirectional
|
||
editing introduced in Emacs 24. If you need the bidirectional
|
||
properties of a character, use `get-char-code-property' with the last
|
||
argument `bidi-class'.
|
||
|
||
** `copy-directory' now copies the source directory as a subdirectory
|
||
of the target directory, if the latter is an existing directory. The
|
||
new optional arg COPY-CONTENTS, if non-nil, makes the function copy
|
||
the contents directly into a pre-existing target directory.
|
||
|
||
** For mouse click input events in the text area, the Y pixel
|
||
coordinate in the POSITION list now counts from the top of the text
|
||
area, excluding any header line. Previously, it counted from the top
|
||
of the header line.
|
||
|
||
** Support for "old-style" backquotes, obsolete for 10+ years, has
|
||
been further reduced. Now a backquote not followed by a space is
|
||
always treated as a "new-style" backquote. Please remove all
|
||
"old-style" backquotes from your code. If your code uses backquotes
|
||
as documented in the Elisp manual, and compiles without warning, then
|
||
you have nothing to do in this regard. Code not following the
|
||
appropriate conventions may fail to compile.
|
||
|
||
The most common cause of trouble seems to be an old-style backquote
|
||
followed by a newline. Another cause of trouble is vector notation
|
||
for key sequence notation: instead of [(control ,)] and [(control ')],
|
||
you should write [(control ?,)] and [(control ?')], which will work in
|
||
older Emacsen too.
|
||
|
||
** The macro `eval-at-startup' was removed in Emacs 23.2, but this
|
||
was not advertised at the time. The function `custom-initialize-delay'
|
||
replaced all known uses.
|
||
|
||
** `view-buffer' now treats special mode-class in the same way that
|
||
`view-file' has since Emacs 22 (i.e. it won't enable View mode if the
|
||
major mode is special).
|
||
|
||
** Menu and tool bar changes
|
||
|
||
*** During startup, Emacs no longer adds entries for `menu-bar-lines'
|
||
and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'.
|
||
With these alist entries omitted, `make-frame' checks the value of the
|
||
variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create
|
||
a menu-bar or tool-bar, respectively. If the alist entries are added,
|
||
they override the value of `menu-bar-mode'/`tool-bar-mode'.
|
||
|
||
*** The menu bar bindings's caches are not used any more.
|
||
Use (where-is-internal <def> nil t) instead.
|
||
|
||
** Regions created by mouse dragging are now normal active regions,
|
||
similar to those created by shift-selection (see Selection changes
|
||
above). In previous Emacs versions, these regions were delineated by
|
||
`mouse-drag-overlay'; that variable has been removed.
|
||
|
||
** The fourth argument of `filter-buffer-substring' has been removed.
|
||
If you want to remove text properties from the final result, simply
|
||
pass the result through substring-no-properties.
|
||
|
||
** cl.el no longer provides `cl-19'.
|
||
|
||
** The following obsolete functions and aliases have been removed
|
||
(the appropriate new function is given in parentheses; "not needed"
|
||
means you can just remove all calls to the function in question):
|
||
|
||
*** `comint-kill-output' (`comint-delete-output')
|
||
*** `decompose-composite-char' (`char-to-string')
|
||
*** `outline-visible' (`outline-invisible-p')
|
||
*** `internal-find-face' (`facep')
|
||
*** `internal-get-face' (`facep and check-face')
|
||
*** `frame-update-faces' (not needed)
|
||
*** `frame-update-face-colors' (`frame-set-background-mode')
|
||
*** `x-frob-font-weight' and `x-frob-font-slant' (`make-face-*' functions)
|
||
*** `x-make-font-bold and x-make-font-demibold (`make-face-bold')
|
||
*** `x-make-font-italic' and `x-make-font-oblique' (`make-face-italic')
|
||
*** `x-make-font-bold-italic' (`make-face-bold-italic')
|
||
*** `x-make-font-unbold' (`make-face-unbold')
|
||
*** `x-make-font-unitalic' (`make-face-unitalic')
|
||
*** `mldrag-drag-mode-line' (`mouse-drag-mode-line')
|
||
*** `mldrag-drag-vertical-line' (`mouse-drag-vertical-line')
|
||
*** `iswitchb-default-keybindings' (`iswitchb-mode')
|
||
*** `char-bytes' (== 1)
|
||
*** `isearch-return-char' (`isearch-printing-char')
|
||
*** `make-local-hook' (not needed)
|
||
*** `set-screen-height' (`set-frame-height')
|
||
*** `set-screen-width' (`set-frame-width')
|
||
|
||
** The following obsolete variables and varaliases have been removed
|
||
(the appropriate new variable is given in parentheses):
|
||
|
||
*** `checkdoc-minor-keymap' (`checkdoc-minor-mode-map')
|
||
*** `vc-header-alist' (`vc-BACKEND-header')
|
||
*** `directory-sep-char' (== ?/)
|
||
*** `font-lock-defaults-alist' (`font-lock-defaults')
|
||
*** `e' (`float-e').
|
||
|
||
** The following obsolete files were removed:
|
||
sc.el, x-menu.el, rnews.el, rnewspost.el
|
||
|
||
** The format of the finder-inf.el file has changed, since the Finder
|
||
mechanism is now based on the package system. The variable
|
||
`finder-package-info' is replaced by `package--builtins' and
|
||
`finder-keywords-hash'.
|
||
|
||
** When generating autoloads, `update-directory-autoloads' no longer
|
||
assumes every inspected file is in your `load-path'. It instead
|
||
generates relative names according to the current `load-path'.
|
||
|
||
|
||
* Lisp changes in Emacs 24.1
|
||
|
||
** Code can now use lexical scoping by default instead of dynamic scoping.
|
||
The `lexical-binding' variable enables lexical scoping for local
|
||
variables. It is typically set via a file-local variable in the first
|
||
line of the file, in which case it applies to all the code in that
|
||
file.
|
||
|
||
*** `eval' takes a new optional argument `lexical' to choose the new lexical
|
||
binding instead of the old dynamic binding mode.
|
||
|
||
*** Lexically scoped interpreted functions are represented with a new form
|
||
of function value which looks like (closure ENV ARGS &rest BODY).
|
||
|
||
*** New macro `letrec' to define recursive local functions.
|
||
|
||
*** `defvar' and `defconst' now mark the variable as special (dynamic).
|
||
So do `defcustom' and other forms that call `defvar' as a subroutine.
|
||
|
||
*** New function `special-variable-p' to check whether a variable is
|
||
declared as dynamically bound.
|
||
|
||
*** The form ((lambda ...) ...) is deprecated.
|
||
|
||
** An Emacs Lisp testing tool is now included.
|
||
Emacs Lisp developers can use this tool to write automated tests for
|
||
their code. See the ERT info manual for details.
|
||
|
||
** Changes for bidirectional display and editing
|
||
|
||
*** New function `current-bidi-paragraph-direction'.
|
||
This returns the base direction of the paragraph at point.
|
||
|
||
*** New function `bidi-string-mark-left-to-right'.
|
||
Given a string containing characters from right-to-left scripts, this
|
||
function returns another string which can be safely inserted into a
|
||
buffer, such that any following text will be always displayed to the
|
||
right of that string. (This works by appending an invisible Unicode
|
||
"LEFT-TO-RIGHT MARK" character if the argument string might need it.)
|
||
|
||
This is useful when the buffer has overall left-to-right paragraph
|
||
direction and you need to insert a string whose contents are not known
|
||
in advance, without disrupting the layout of the line.
|
||
|
||
** Window changes
|
||
|
||
*** Window tree functions are accessible in Elisp.
|
||
Functions are provided to return the parent, siblings or child windows
|
||
of any window including internal windows (windows not associated with a
|
||
buffer) in the window tree.
|
||
|
||
**** New function `window-valid-p' gives non-nil for live and internal
|
||
windows.
|
||
|
||
**** Window manipulation can deal with internal windows.
|
||
Many window handling functions like `split-window', `delete-window', or
|
||
`delete-other-windows' as well as the window resizing functions can now
|
||
act on any window including internal ones.
|
||
|
||
*** window-total-height/-width vs window-body-height/-width.
|
||
The function `window-height' has been renamed to `window-total-height'
|
||
and `window-width' has been renamed to `window-body-width'. The old
|
||
names are provided as aliases. Two new functions `window-total-width'
|
||
and `window-body-height' are provided.
|
||
|
||
*** Window parameters specific to window handling functions.
|
||
For each window you can specify a parameter to override the default
|
||
behavior of a number of functions like `split-window', `delete-window'
|
||
and `delete-other-windows'. The variable `ignore-window-parameters'
|
||
allows to ignore processing such parameters.
|
||
|
||
*** New semantics of third argument of `split-window'.
|
||
The third argument of `split-window' has been renamed to SIDE and can be
|
||
set to any of the values 'below, 'right, 'above, or 'left to make the
|
||
new window appear on the corresponding side of the window that shall be
|
||
split. Any other value of SIDE will cause `split-window' to split the
|
||
window into two side-by-side windows as before.
|
||
|
||
*** Window resizing functions.
|
||
A new standard function for resizing windows called `window-resize' has
|
||
been introduced. This and all other functions for resizing windows no
|
||
longer delete any windows when they become too small.
|
||
|
||
*** Deleting the selected window now selects the most recently selected
|
||
live window on that frame instead.
|
||
|
||
*** `adjust-window-trailing-edge' adjustments.
|
||
`adjust-window-trailing-edge' can now deal with fixed-size windows and
|
||
is able to resize other windows if a window adjacent to the trailing
|
||
edge cannot be shrunk any more. This makes its behavior more similar to
|
||
that of Emacs 21 without compromising, however, its inability to delete
|
||
windows which was introduced in Emacs 22.
|
||
|
||
*** Window-local buffer lists.
|
||
Windows now have local buffer lists. This means that removing a buffer
|
||
from display in a window will preferably show the buffer previously
|
||
shown in that window with its previous window-start and window-point
|
||
positions. This also means that the same buffer may be automatically
|
||
shown twice even if it already appears in another window.
|
||
|
||
*** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW,
|
||
which if non-nil requires the buffer to be displayed in the currently
|
||
selected window, signaling an error otherwise. If nil, another window
|
||
can be used, e.g. if the selected one is strongly dedicated.
|
||
|
||
*** `split-window-vertically' and `split-window-horizontally' renamed
|
||
to `split-window-below' and `split-window-right' respectively.
|
||
The old names are kept as aliases.
|
||
|
||
*** Display actions
|
||
|
||
**** The second arg to `display-buffer' and `pop-to-buffer' is now
|
||
named ACTION, and takes a display action of the same form as
|
||
`display-buffer-base-action' (see Changes, above). A non-nil,
|
||
non-list value is treated specially, as the old meaning.
|
||
|
||
**** New variable `display-buffer-overriding-action'.
|
||
|
||
**** The procedure of `display-buffer' etc. to choose a window is
|
||
determined by combining `display-buffer-overriding-action',
|
||
`display-buffer-alist', the ACTION arg, `display-buffer-base-action',
|
||
and `display-buffer-fallback-action'. The second and fourth of these
|
||
are user-customizable variables.
|
||
|
||
See the docstring of `display-buffer' for details.
|
||
|
||
*** New functions `window-state-get' and `window-state-put'.
|
||
These functions allow to save and restore the state of an arbitrary
|
||
frame or window as an Elisp object.
|
||
|
||
** Completion
|
||
|
||
*** New variable `completion-extra-properties' used to specify extra
|
||
properties of the current completion:
|
||
- :annotate-function, same as the old completion-annotate-function.
|
||
- :exit-function, function to call after completion took place.
|
||
|
||
*** Functions on `completion-at-point-functions' can return any of the
|
||
properties valid for `completion-extra-properties'.
|
||
|
||
*** `completion-annotate-function' is obsolete.
|
||
|
||
*** New `metadata' method for completion tables. The metadata thus returned
|
||
can specify various details of the data returned by `all-completions':
|
||
- `category' is the kind of objects returned (e.g., `buffer', `file', ...),
|
||
used to select a style in completion-category-overrides.
|
||
- `annotation-function' to add annotations in *Completions*.
|
||
- `display-sort-function' to specify how to sort entries in *Completions*.
|
||
- `cycle-sort-function' to specify how to sort entries when cycling.
|
||
|
||
*** `minibuffer-local-filename-must-match-map' is not used any more.
|
||
Instead, the bindings in `minibuffer-local-filename-completion-map'
|
||
are combined with `minibuffer-local-must-match-map'.
|
||
|
||
*** New variable `completing-read-function' allows overriding the
|
||
behavior of `completing-read'.
|
||
|
||
** `glyphless-char-display' can now distinguish between graphical and
|
||
text terminal display, via a char-table entry that is a cons cell.
|
||
|
||
** `pre-command-hook'/`post-command-hook' are not reset to nil on error.
|
||
Instead, the offending function is removed.
|
||
|
||
** New hook types
|
||
|
||
*** New function `run-hook-wrapped' for running an abnormal hook by
|
||
passing the hook functions as arguments to a "wrapping" function.
|
||
Like `run-hook-with-args-until-success', it stops at the first
|
||
non-nil return value.
|
||
|
||
*** New macro `with-wrapper-hook' for running an abnormal hook as a
|
||
set of "wrapping" filters, similar to around advice.
|
||
(A version of this macro was actually added in Emacs 23.2 but was not
|
||
advertised at the time.)
|
||
|
||
** Debugger changes
|
||
|
||
*** New macro `condition-case-unless-debug' (this was actually added in
|
||
Emacs 23.1 as condition-case-no-debug, but not advertised)
|
||
|
||
*** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised.
|
||
|
||
*** Variable `stack-trace-on-error' removed.
|
||
|
||
*** The debugger can now "continue" from an error, which means it will
|
||
jump to the error handler as if the debugger had not been invoked
|
||
instead of jumping all the way to the top-level.
|
||
|
||
*** Set `debug-on-event' to enter the debugger on events like SIGUSR1.
|
||
This can be useful when `inhibit-quit' is set.
|
||
|
||
** The new function `server-eval-at' allows evaluation of Lisp forms on
|
||
named Emacs server instances.
|
||
|
||
** `call-process' and `call-process-region' allow a `(:file "file")' spec
|
||
to redirect STDOUT to a file.
|
||
|
||
** The function `format-time-string' now supports the %N directive,
|
||
for higher-resolution time stamps.
|
||
|
||
** New input reading functions
|
||
|
||
*** New function `read-char-choice' reads a restricted set of
|
||
characters, discarding any inputs not inside the set.
|
||
|
||
*** The command `read-color' now requires a match for a color name
|
||
or RGB triplet, instead of signaling an error if the user provides
|
||
invalid input.
|
||
|
||
**** `facemenu-read-color' is now an alias for `read-color'.
|
||
|
||
** `image-library-alist' is renamed to `dynamic-library-alist'.
|
||
The variable is now used to load all kind of supported dynamic libraries,
|
||
not just image libraries. The previous name is still available as an
|
||
obsolete alias.
|
||
|
||
** Syntax parsing changes
|
||
|
||
*** New variable `syntax-propertize-function'.
|
||
This replaces `font-lock-syntactic-keywords' which is now obsolete.
|
||
This allows syntax-table properties to be set independently from font-lock:
|
||
just call syntax-propertize to make sure the text is propertized.
|
||
Together with this new variable come a new hook
|
||
syntax-propertize-extend-region-functions, as well as two helper functions:
|
||
syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
|
||
as-is; and syntax-propertize-rules which provides a new way to specify
|
||
syntactic rules.
|
||
|
||
*** Syntax tables support a new "comment style c" additionally to style b.
|
||
|
||
** New hook `post-self-insert-hook', run after `self-insert-command'.
|
||
|
||
** frame-local variables cannot be let-bound any more.
|
||
|
||
** Major and minor mode changes
|
||
|
||
*** `set-auto-mode' now respects mode: local variables at the end of files,
|
||
as well as those in the -*- line.
|
||
|
||
*** `prog-mode' is a new major mode from which programming modes
|
||
should be derived.
|
||
|
||
**** `prog-mode-hook' can be used to enable features for programming
|
||
modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable
|
||
on-the-fly spell checking for comments and strings.
|
||
|
||
*** New hook `change-major-mode-after-body-hook', run by
|
||
`run-mode-hooks' just before any other mode hooks.
|
||
|
||
*** Enabled globalized minor modes can be disabled in specific major modes.
|
||
If the global mode is global-FOO-mode, then run (FOO-mode -1) in the
|
||
major mode's hook, where FOO-mode toggles the mode on a per-buffer basis.
|
||
|
||
*** `define-minor-mode' accepts new keywords :variable, :after-hook.
|
||
|
||
** File-handling changes
|
||
|
||
*** `delete-file' and `delete-directory' now accept optional arg TRASH.
|
||
Trashing is performed if TRASH and `delete-by-moving-to-trash' are
|
||
both non-nil. Interactively, TRASH defaults to t, unless a prefix
|
||
argument is supplied (see Trash changes, above).
|
||
|
||
*** New file predicates: `file-equal-p', `file-in-directory-p'.
|
||
|
||
** Tool-bars can display separators.
|
||
Tool-bar separators are handled like menu separators in menu-bar maps,
|
||
i.e. via menu entries of the form `(menu-item "--")'.
|
||
|
||
** Image API
|
||
|
||
*** Animated images support (currently animated gifs only).
|
||
|
||
**** `image-animated-p' returns non-nil if an image can be animated.
|
||
|
||
**** `image-animate' animates a supplied image spec.
|
||
|
||
**** `image-animate-timer' returns the timer object for an image that
|
||
is being animated.
|
||
|
||
*** `image-extension-data' has been renamed to `image-metadata'.
|
||
The old name is an obsolete alias to the new one.
|
||
|
||
*** Image mode can view any image type that ImageMagick supports.
|
||
This requires Emacs to be built with ImageMagick support.
|
||
|
||
**** New function `imagemagick-types', defined if ImageMagick support
|
||
is enabled, returns a list of image file extensions that your
|
||
ImageMagick installation supports.
|
||
|
||
**** New function `imagemagick-register-types' enables ImageMagick
|
||
image types in Image mode and in `create-image' and other helper
|
||
functions.
|
||
|
||
**** New option `imagemagick-types-inhibit' excludes certain
|
||
ImageMagick image types from `imagemagick-register-types'.
|
||
|
||
**** With ImageMagick support, there are extra Image mode commands to
|
||
resize and rotate images: `image-transform-fit-to-height',
|
||
`image-transform-fit-to-width', `image-transform-set-rotation', and
|
||
`image-transform-set-scale'.
|
||
|
||
** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and
|
||
passes it to the mail user agent function. This argument specifies an
|
||
action for returning to the caller after finishing with the mail. For
|
||
example, this is used by Rmail to optionally delete a mail window.
|
||
|
||
** XML and HTML parsing
|
||
If Emacs is compiled with libxml2 support, there are two new
|
||
functions: `libxml-parse-html-region' (which parses "real world" HTML)
|
||
and `libxml-parse-xml-region' (which parses XML). Both return an
|
||
Emacs Lisp parse tree.
|
||
|
||
** Networking and encryption changes
|
||
|
||
*** `open-network-stream' can now be used to open an encrypted stream.
|
||
It now accepts an optional `:type' parameter for initiating a TLS
|
||
connection, directly or via STARTTLS. To do STARTTLS, additional
|
||
parameters (`:end-of-command', `:success', `:capabilities-command')
|
||
must also be supplied.
|
||
|
||
*** New library gnutls.el.
|
||
The new function `gnutls-available-p' returns non-nil if Emacs is
|
||
built with GnuTLS support. The main entry points are
|
||
`open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use
|
||
these functions through `open-network-stream', because that can
|
||
upgrade connections through STARTTLS opportunistically or use plain
|
||
SSL, depending on your needs. For debugging, set `gnutls-log-level'
|
||
greater than 0.
|
||
|
||
*** New primitive `secure-hash' that supports many secure hash algorithms:
|
||
md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library
|
||
sha1.el has been removed. The `sha1' feature is provided by default.
|
||
|
||
** Isearch
|
||
|
||
*** New hook `isearch-update-post-hook' that runs in `isearch-update'.
|
||
|
||
** Progress reporters can now "spin".
|
||
The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
|
||
now be nil, or omitted. This makes a "non-numeric" reporter. Each
|
||
time you call `progress-reporter-update' on that progress reporter,
|
||
with a nil or omitted VALUE argument, the reporter message is
|
||
displayed with a "spinning bar".
|
||
|
||
** New variable `revert-buffer-in-progress-p' is true while a buffer is
|
||
being reverted, even if the buffer has a local `revert-buffer-function'.
|
||
|
||
** New variables `delayed-warnings-list' and `delayed-warnings-hook'.
|
||
If delayed-warnings-list is non-nil, the command loop calls
|
||
`delayed-warnings-hook' after `post-command-hook'. At present, this
|
||
is only used by Emacs on some platforms to display warnings during
|
||
startup, which might otherwise not be noticed. This uses the
|
||
functions `display-delayed-warnings' and `collapse-delayed-warnings'.
|
||
|
||
** rx.el has a new `group-n' construct for explicitly numbered groups.
|
||
|
||
** New function `make-composed-keymap' that constructs a new keymap
|
||
from multiple input maps. You can use this to make a keymap that
|
||
inherits from multiple maps, eg:
|
||
(set-keymap-parent newmap (make-composed-keymap othermap parent))
|
||
|
||
** New function `string-prefix-p'.
|
||
(This was actually added in Emacs 23.2 but was not advertised at the time.)
|
||
|
||
** New reader macro ## that stands for the empty symbol.
|
||
This means that the empty symbol can now be read back. Also, #: by itself
|
||
(when not immediately followed by a possible symbol character) stands for
|
||
an empty uninterned symbol.
|
||
|
||
** New math functions `isnan', `copysign', `frexp', `ldexp'.
|
||
|
||
** The following functions and variables are obsolete:
|
||
|
||
*** `tooltip-use-echo-area' is obsolete.
|
||
Rather than setting this to t, disable Tooltip mode instead.
|
||
|
||
*** buffer-substring-filters is obsolete.
|
||
Use `filter-buffer-substring-functions' instead.
|
||
|
||
*** `byte-compile-disable-print-circle' is obsolete.
|
||
|
||
*** `deferred-action-list' and `deferred-action-function' are obsolete.
|
||
Use `post-command-hook' instead.
|
||
|
||
*** `font-lock-maximum-size' is obsolete.
|
||
|
||
|
||
* Changes in Emacs 24.1 on non-free operating systems
|
||
|
||
** On MS Windows, Emacs warns when using the obsolete init file _emacs,
|
||
and also when HOME is set to C:\ by default.
|
||
|
||
** New configure.bat options
|
||
|
||
*** --enable-checking builds Emacs with extra runtime checks.
|
||
|
||
*** --distfiles specifies files to be included in binary distribution.
|
||
|
||
*** --without-gnutls disables automatic GnuTLS detection.
|
||
|
||
*** --lib for general library linkage, works with the USER_LIBS build variable.
|
||
|
||
** New make target `dist' to create binary distribution for MS Windows.
|
||
|
||
** The Lisp function `w32-default-color-map' is now obsolete.
|
||
(It is only used internally in the Emacs C code.)
|
||
|
||
** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but
|
||
reappear on mouse-over. (Requires OS X 10.6 or later.)
|
||
|
||
** On Mac OS X, dragging a file into Emacs visits the file, like on
|
||
other platforms, rather than inserting its contents into the buffer.
