Now, text area click input events measure Y from the top of the text area, excluding the header line if any. * src/dispnew.c (buffer_posn_from_coords): Assume that X counts from the start of the text area. * src/keyboard.c (make_lispy_position): For text area clicks, record Y pixel position relative to the text area, excluding header line. Also change X and Y to Lisp_Objects, not pointers; don't return coordinate values via pointers. Pass ON_TEXT_AREA coordinate to buffer_posn_from_coords counting from the start of the text area. (Fposn_at_x_y, make_lispy_event): Callers changed. * src/w32term.c (w32_read_socket): * src/msdos.c (dos_rawgetc): * src/xterm.c (handle_one_xevent): Likewise. * src/window.c (coordinates_in_window): Change X and Y to ints rather than pointers; don't return coordinates via pointers. (struct check_window_data): Change X and Y from pointers to ints. (window_from_coordinates): Remove args WX and WY; don't return coordinates via pointers. (Fcoordinates_in_window_p, window_from_coordinates): (check_window_containing, Fwindow_at): Callers changed. (window_relative_x_coord): New function. * src/window.h (window_from_coordinates, window_relative_x_coord): Update prototypes. * src/xdisp.c (remember_mouse_glyph): Change window_from_coordinates call. Use window_relative_x_coord. (note_mouse_highlight): Change window_from_coordinates call.

If possible, use M-x report-emacs-bug.
|
||
|
||
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.
|
||
|
||
|
||
* Installation Changes in Emacs 24.1
|
||
|
||
** Configure links against libselinux if it is found.
|
||
You can disable this by using --without-selinux.
|
||
|
||
---
|
||
** By default, the installed Info and man pages are compressed.
|
||
You can disable this by configuring --without-compress-info.
|
||
|
||
---
|
||
** There are 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.
|
||
|
||
---
|
||
** Emacs can be compiled against 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.
|
||
|
||
** There is a 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.
|
||
|
||
---
|
||
** New translation of the Emacs Tutorial in Hebrew is available
|
||
Type `C-u C-h t' to choose it in case your language setup doesn't
|
||
automatically select it.
|
||
|
||
|
||
* Startup Changes in Emacs 24.1
|
||
|
||
** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
|
||
command line arguments no longer have any effect. (They were declared
|
||
obsolete in Emacs 23.)
|
||
|
||
|
||
* Changes in Emacs 24.1
|
||
|
||
** emacsclient changes
|
||
|
||
*** New emacsclient argument --parent-id ID can be used to open a
|
||
client frame in parent X window ID, via XEmbed. This works like the
|
||
--parent-id argument to Emacs.
|
||
|
||
*** If emacsclient shuts down as a result of Emacs signalling an
|
||
error, its exit status is 1.
|
||
|
||
** Completion can cycle, depending on completion-cycle-threshold.
|
||
|
||
** auto-mode-case-fold is now enabled by default.
|
||
|
||
+++
|
||
** Emacs now supports display and editing of bidirectional text.
|
||
|
||
See the node "Bidirectional Editing" in the Emacs Manual for some
|
||
initial documentation.
|
||
|
||
To turn this on in any given buffer, set the buffer-local variable
|
||
`bidi-display-reordering' to a non-nil value. The default is nil.
|
||
|
||
The buffer-local variable `bidi-paragraph-direction', if non-nil,
|
||
forces each paragraph in the buffer to have its base direction
|
||
according to the value of this variable. Possible values are
|
||
`right-to-left' and `left-to-right'. If the value is nil (the
|
||
default), Emacs determines the base direction of each paragraph from
|
||
its text, as specified by the Unicode Bidirectional Algorithm.
|
||
|
||
The function `current-bidi-paragraph-direction' returns the actual
|
||
value of paragraph base direction at point.
|
||
|
||
Reordering of bidirectional text for display in Emacs is a "Full
|
||
bidirectionality" class implementation of the Unicode Bidirectional
|
||
Algorithm.
|
||
|
||
Note that some advanced display features, such as overlay strings and
|
||
`display' text properties, do not yet work correctly when
|
||
bidirectional text is reordered for display.
|
||
|
||
** GTK scroll-bars are now placed on the right by default.
|
||
Use `set-scroll-bar-mode' to change this.
|
||
|
||
** GTK tool bars can have just text, just images or images and text.
|
||
Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
|
||
is taken from the desktop settings.
|
||
|
||
** GTK tool bars can be placed on the left/right or top/bottom 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.
|
||
|
||
** ImageMagick support.
|
||
It is now possible to use the ImageMagick library to load many new
|
||
image formats in Emacs. By default, Emacs links with the ImageMagick
|
||
libraries if they are present at build time. To disable this, use
|
||
the configure option `--without-imagemagick'.
|
||
|
||
The new function `imagemagick-types' returns a list of image file
|
||
extensions that your installation of ImageMagick supports. The
|
||
function `imagemagick-register-types' enables ImageMagick support for
|
||
these image types, minus those listed in `imagemagick-types-inhibit'.
|
||
|
||
See the Emacs Lisp Reference Manual for more information.
|
||
|
||
** The 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 turn that
|
||
off by customizing x-gtk-use-system-tooltips.
|
||
|
||
** Lucid menus and dialogs can display antialiased fonts if Emacs is built
|
||
with Xft. To change font, use X resource faceName, for example:
|
||
Emacs.pane.menubar.faceName: Courier-12
|
||
Set faceName to none and use font to use the old X fonts.
|
||
|
||
+++
|
||
** Enhanced support for characters that have no glyphs in available fonts
|
||
If a character has no glyphs in any of the available fonts, Emacs by
|
||
default will display it either as a hexadecimal code in a box or as a
|
||
thin 1-pixel space. In addition to these two methods, Emacs can
|
||
display these characters as empty box, as an acronym, or not display
|
||
them at all. To change how these characters are displayed, customize
|
||
the variable `glyphless-char-display-control'.
|
||
|
||
On character terminals these methods are used for characters that
|
||
cannot be encoded by the `terminal-coding-system'.
|
||
|
||
** On graphical displays, the mode-line no longer ends in dashes.
|
||
|
||
** 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, and
|
||
optionally when copying files. To this end, copy-file has an extra
|
||
optional argument, and backup-buffer and friends include the SELinux
|
||
context in their return values.
|
||
|
||
*** The new functions file-selinux-context and set-file-selinux-context
|
||
get and set the SELinux context of a file.
|
||
|
||
*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
|
||
for remote machines which support SELinux.
|
||
|
||
** The function kill-emacs is now run upon receipt of the signals SIGTERM
|
||
and SIGHUP, and upon SIGINT in batch mode.
|
||
|
||
** kill-emacs-hook is now also run in batch mode.
|
||
|
||
** New scrolling commands `scroll-up-command' and `scroll-down-command'
|
||
(bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
|
||
of buffer at first key-press (instead moves to top/bottom of buffer)
|
||
when a new variable `scroll-error-top-bottom' is non-nil.
|
||
|
||
** 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'.
|
||
|
||
** 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'.
|
||
|
||
** New option `list-colors-sort' defines the color sort order
|
||
for `list-colors-display'.
|
||
|
||
** An Emacs Lisp package manager is now included.
|
||
This is a convenient way to download and install additional packages,
|
||
from a package repository at 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 and activated
|
||
automatically when Emacs starts up. To disable this, set
|
||
`package-enable-at-startup' to nil. To change which packages are
|
||
loaded, customize `package-load-list'.
|
||
|
||
** Custom Themes
|
||
|
||
*** `M-x customize-themes' lists Custom themes which can be enabled.
|
||
|
||
*** New option `custom-theme-load-path' is the load path for themes.
|
||
Emacs no longer looks for custom themes in `load-path'. The default
|
||
is to search in `custom-theme-directory', followed by a built-in theme
|
||
directory named "themes/" in `data-directory'.
|
||
|
||
** The user option `remote-file-name-inhibit-cache' controls whether
|
||
the remote file-name cache is used for read access.
|
||
|
||
** The standalone programs lib-src/digest-doc and sorted-doc have been
|
||
replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.
|
||
|
||
|
||
* Editing Changes in Emacs 24.1
|
||
|
||
+++
|
||
** There is a new command `count-words-region', which does what you expect.
|
||
|
||
** completion-at-point is now an alias for complete-symbol.
|
||
|
||
** Deletion changes
|
||
|
||
*** New option `delete-active-region'.
|
||
If non-nil, C-d, [delete], and DEL delete the region if it is active
|
||
and no prefix argument is given. If set to `kill', these commands
|
||
kill instead.
|
||
|
||
*** New command `delete-forward-char', bound to C-d and [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; you
|
||
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 other X applications. The exact changes are
|
||
described below; in short, mouse commands to select and paste text now
|
||
use the primary selection, while all other commands for killing and
|
||
yanking text now use the clipboard.
|
||
|
||
*** Merely selecting text (e.g. with drag-mouse-1) does not add it to
|
||
the kill-ring. On systems with a primary selection separate from the
|
||
clipboard (such as X), the selected text is put in the primary
|
||
selection.
|
||
|
||
*** mouse-2 is now bound to `mouse-yank-primary', which pastes from
|
||
the primary selection regardless of the contents of the kill-ring.
|
||
|
||
*** Commands that kill text or copy it to the kill-ring (M-w, C-w,
|
||
C-k, etc.) also put the killed text into the clipboard. This change
|
||
also means that the "Copy", "Cut", and "Paste" items in the "Edit"
|
||
menu are now exactly equivalent to, respectively M-w, C-w, and C-y.
|
||
|
||
*** Yank commands, such as C-y and M-y, retrieve text from the
|
||
clipboard if it is available.
|
||
|
||
*** The above changes are reflected in the following new defaults:
|
||
|
||
**** `select-active-regions' now defaults to t.
|
||
It also accepts a new value, `only', which means to only set the
|
||
primary selection for temporarily active regions (usually made by
|
||
mouse-dragging or shift-selection).
|
||
|
||
**** `mouse-2' is now bound to `mouse-yank-primary'.
|
||
Previously, it was bound to `mouse-yank-at-click' (which is now
|
||
unbound by default).
|
||
|
||
**** `x-select-enable-clipboard' now defaults to t on all platforms.
|
||
Note that this variable was already non-nil by default on MS-Windows,
|
||
which does not support the primary selection between applications.
|
||
|
||
**** `x-select-enable-primary' now defaults to nil.
|
||
This variable exists only on X; its default value was t in previous
|
||
versions.
|
||
|
||
**** `mouse-drag-copy-region' now defaults to nil.
|
||
|
||
*** To return to the previous behavior, where mouse commands use the
|
||
clipboard, change `mouse-drag-copy-region' and (on X only)
|
||
`x-select-enable-primary' to t. If you don't want Emacs to put the
|
||
text into the clipboard, only to the primary selection, additionally
|
||
set `x-select-enable-clipboard' to nil.
|
||
|
||
*** Support for X cut buffers has been removed.
|
||
|
||
|
||
* Changes in Specialized Modes and Packages in Emacs 24.1
|
||
|
||
** shell-mode can track your cwd by reading it from your prompt.
|
||
Just set shell-dir-cookie-re to an appropriate regexp.
|
||
|
||
** Modula-2 mode provides auto-indentation.
|
||
|
||
** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
|
||
|
||
** FIXME: xdg-open for browse-url and reportbug, 2010/08.
|
||
|
||
** Archive Mode has basic support to browse 7z archives.
|
||
|
||
** ERC changes
|
||
|
||
*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
|
||
If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
|
||
successful NickServ identification, or after `erc-autojoin-delay'
|
||
seconds. The default value, 'ident, means to autojoin immediately
|
||
after connecting.
|
||
|
||
*** 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.
|
||
|
||
** In ido-mode, C-v is no longer bound to ido-toggle-vc.
|
||
The reason is that this interferes with cua-mode.
|
||
|
||
** partial-completion-mode is now obsolete.
|
||
You can get a comparable behavior with:
|
||
(setq completion-styles '(partial-completion initials))
|
||
(setq completion-pcm-complete-word-inserts-delimiters t)
|
||
|
||
** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
|
||
|
||
** server can listen on a specific port using the server-port option.
|
||
|
||
** Calendar, Diary, and Appt
|
||
|
||
---
|
||
*** 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.
|
||
|
||
---
|
||
*** 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
|
||
|
||
** 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.
|
||
|
||
*** Custom options now start out hidden if at their default values.
|
||
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.
|
||
|
||
** Dired-x
|
||
|
||
*** dired-jump and dired-jump-other-window called with a prefix argument
|
||
read a file name from the minibuffer instead of using buffer-file-name.
|
||
|
||
** Directory local variables can apply to file-less buffers.
|
||
For example, adding "(diff-mode . ((mode . whitespace)))" to your
|
||
.dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers.
|
||
|
||
** SQL Mode enhancements.
|
||
|
||
*** Several variables have been marked as safe local variables. The
|
||
variables `sql-product', `sql-user', `sql-server', `sql-database' and
|
||
`sql-port' can now be safely used as local variables.
|
||
|
||
*** `sql-dialect' is a synonym for `sql-product'.
|
||
|
||
*** Added ability to login with a port on MySQL and Postgres.
|
||
The custom variable `sql-port' can be specified for connection to
|
||
MySQL or Postgres servers. By default, the port is not listed in
|
||
either login parameter, but will be added to the command line if set
|
||
to a non-zero value.
|
||
|
||
*** Dynamic selection of product in an SQL interactive session.
|
||
If you use `sql-product-interactive' to start an SQL interactive
|
||
session it uses the current value of `sql-product'. Preceding the
|
||
invocation with C-u will force it to ask for the product before
|
||
creating the session.
|
||
|
||
*** Renaming a SQL interactive buffer when it is created.
|
||
Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
|
||
`sql-mysql', etc.) with C-u will force a new interactive session to be
|
||
started and will prompt for the new name. This will reduce the need
|
||
for `sql-rename-buffer' is most common use cases.
|
||
|
||
*** Command continuation prompts in SQL interactive mode are suppressed.
|
||
Multiple line commands in SQL interactive mode, generate command
|
||
continuation prompts which needlessly confuse the output. These
|
||
prompts are now filtered out from the output. This 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.
|
||
|
||
*** Custom variables control 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 lists consist of the following five tokens: `user', `password',
|
||
`database', `server', and `port'. The order in which they appear is
|
||
the order in which they are prompted. The tokens symbols can be
|
||
replaced by a sublist starting with the token and followed by a plist
|
||
which control the prompting for values. The tokens `user',
|
||
`database', and `server' each can take a property of :default which
|
||
specifies the value to be used if no value is entered. The
|
||
`database', `server', and `port' tokens handle the :completion
|
||
property which restricts the entry to either one of the values in the
|
||
list or to one of the values returned by the function provided as the
|
||
property value. The `database' and `server' tokens also accept the
|
||
:file property whose value is a regexp to identify useful file names.
|
||
|
||
(user :default DEF)
|
||
(database :default DEF
|
||
:file FILEPAT
|
||
:completion COMPLETE)
|
||
(server :default DEF
|
||
:file FILEPAT
|
||
:completion COMPLETE)
|
||
|
||
The FILEPAT when :file is specified is a regexp that will match valid
|
||
file names (without the directory portion). Generally these strings
|
||
will be of the form ".+\.SUF" where SUF is the desired file suffix.
|
||
|
||
When :completion is specified, the COMPLETE corresponds to the
|
||
PREDICATE argument to the `completing-read' function (a list of
|
||
possible values or a function returning such a list).
|
||
|
||
*** Added `sql-connection-alist' to record login parameter values.
|
||
An alist for recording different username, database and server
|
||
values. If there are multiple databases that you connect to the
|
||
parameters needed can be stored in this alist.
|
||
|
||
For example, the following might be set in the user's init.el:
|
||
|
||
(setq sql-connection-alist

||
'((dev (sql-product 'sqlite)
|
||
(sql-database "/home/mmaug/dev.db"))
|
||
(prd (sql-product 'oracle)
|
||
(sql-user "mmaug")
|
||
(sql-database "iprd2a"))))
|
||
|
||
This defines two connections named "dev" and "prd".
|
||
|
||
*** Added `sql-connect' to use predefined connections.
|
||
Sets the login parameters based on the values in the
|
||
`sql-connection-alist' and start a SQL interactive session. Any
|
||
values specified in the connection will not be prompted for.
|
||
|
||
In the example above, if the user were to invoke M-x sql-connect, they
|
||
would be prompted for the connection. The user can respond with
|
||
either "dev" or "prd". The "dev" connection would connect to the
|
||
SQLite database without prompting; the "prd" connection would prompt
|
||
for the users password and then connect to the Oracle database.
|
||
|
||
**** Added SQL->Start... submenu when connections are defined.
|
||
When connections have been defined, there is a submenu available that
|
||
allows the user to select one to start a SQLi session. The "Start
|
||
SQLi Session" item moves to the "Start..." submenu when cnnections
|
||
have been defined.
|
||
|
||
**** Added "Save Connection" menu item in SQLi buffers.
|
||
When a SQLi session is not started by a connection then
|
||
`sql-save-connection' will gather the login params specified for the
|
||
session and save them as a new connection.
|
||
|
||
*** List database objects and details.
|
||
Once a SQL interactive session has been started, you can get a list of
|
||
the objects in the database and see details of those objects. The
|
||
objects shown and the details available are product specific.
|
||
|
||
**** List all objects.
|
||
Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
|
||
objects" will list all the objects in the database. At a minimum it
|
||
lists the tables and views in the database. Preceeding the command by
|
||
universal argument may provide additional details or extend the
|
||
listing to include other schemas objects. The list will appear in a
|
||
separate window in view-mode.
|
||
|
||
**** List Table details.
|
||
Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
|
||
details" will ask for the name of a database table or view and display
|
||
the list of columns in the relation. Preceeding the comand with the
|
||
universal argument may provide additional details about each column.
|
||
The list will appear in a separate window in view-mode.
|
||
|
||
*** Added option `sql-send-terminator'.
|
||
When set makes sure that each command sent with `sql-send-*' commands
|
||
are properly terminated and submitted to the SQL processor.
|
||
|
||
*** Added option `sql-oracle-scan-on'.
|
||
When set commands sent to Oracle's SQL*Plus are scanned for strings
|
||
starting with an ampersand and the user is asked for replacement text.
|
||
In general, the SQL*Plus option SCAN should always be set OFF under
|
||
SQL interactive mode and this option used in its place.
|
||
|
||
*** SQL interactive mode will replace tabs with spaces.
|
||
This prevents the comand interpretter for MySQL and Postgres from
|
||
listing object name completions when being sent text via
|
||
`sql-send-*' functions.
|
||
|
||
*** An API for manipulating SQL product definitions has been added.
|
||
|
||
** s-region.el is now declared obsolete, superceded by shift-select-mode
|
||
enabled by default in 23.1.
|
||
|
||
** gdb-mi
|
||
|
||
*** GDB User Interface migrated to GDB Machine Interface and now
|
||
supports multithread non-stop debugging and debugging of several
|
||
threads simultaneously.
|
||
|
||
** D-Bus
|
||
|
||
*** It is possible now, to access alternative buses than the default
|
||
system or session bus.
|
||
|
||
** Tramp
|
||
|
||
*** The following access methods are discontinued: "ssh1_old",
|
||
"ssh2_old", "scp1_old", "scp2_old" and "fish".
|
||
|
||
|
||
* New Modes and Packages in Emacs 24.1
|
||
|
||
** New global minor modes electric-pair-mode, electric-indent-mode,
|
||
and electric-layout-mode.
|
||
|
||
** 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.
|
||
|
||
|
||
* Incompatible Lisp Changes in Emacs 24.1
|
||
|
||
** 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.
|
||
|
||
** Remove obsolete name `e' (use `float-e' instead).
|
||
|
||
** A backquote not followed by a space is now always treated as new-style.
|
||
|
||
** Test for special mode-class was moved from view-file to view-buffer.
|
||
FIXME: This only says what was changed, but not what are the
|
||
programmer-visible consequences.
|
||
|
||
** Passing a nil argument to a minor mode function now turns the mode
|
||
ON unconditionally.
|
||
|
||
** 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'.
|
||
|
||
** Regions created by mouse dragging are now normal active regions,
|
||
similar to the ones created by shift-selection. In previous Emacs
|
||
versions, these regions were delineated by `mouse-drag-overlay', which
|
||
has now been removed.
|
||
|
||
** cl.el no longer provides `cl-19'.
|
||
|
||
** The following functions and aliases, obsolete since at least Emacs 21.1,
|
||
have been removed:
|
||
comint-kill-output, decompose-composite-char, outline-visible,
|
||
internal-find-face, internal-get-face, frame-update-faces,
|
||
frame-update-face-colors, x-frob-font-weight, x-frob-font-slant,
|
||
x-make-font-bold, x-make-font-demibold, x-make-font-unbold
|
||
x-make-font-italic, x-make-font-oblique, x-make-font-unitalic
|
||
x-make-font-bold-italic, mldrag-drag-mode-line, mldrag-drag-vertical-line,
|
||
iswitchb-default-keybindings, char-bytes, isearch-return-char,
|
||
make-local-hook
|
||
|
||
** The following variables and aliases, obsolete since at least Emacs 21.1,
|
||
have been removed:
|
||
checkdoc-minor-keymap, vc-header-alist, directory-sep-char,
|
||
font-lock-defaults-alist
|
||
|
||
** The following files, obsolete since at least Emacs 21.1, have been removed:
|
||
sc.el, x-menu.el, rnews.el, rnewspost.el
|
||
|
||
** FIXME finder-inf.el changes.
|
||
|
||
|
||
* Lisp changes in Emacs 24.1
|
||
|
||
** `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.
|
||
|
||
** New variable syntax-propertize-function to set syntax-table properties.
|
||
Replaces font-lock-syntactic-keywords which are 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.
|
||
|
||
** New hook post-self-insert-hook run at the end of self-insert-command.
|
||
|
||
+++
|
||
** Syntax tables support a new "comment style c" additionally to style b.
|
||
** frame-local variables cannot be let-bound any more.
|
||
** prog-mode is a new major-mode meant to be the parent of programming mode.
|
||
** define-minor-mode accepts a new keyword :variable.
|
||
|
||
** `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).
|
||
|
||
** buffer-substring-filters is obsoleted by filter-buffer-substring-functions.
|
||
|
||
** New completion style `substring'.
|
||
|
||
** `facemenu-read-color' is now an alias for `read-color'.
|
||
The command `read-color' now requires a match for a color name or RGB
|
||
triplet, instead of signalling an error if the user provides a invalid
|
||
input.
|
||
|
||
|
||
** Image API
|
||
|
||
*** When the image type is one of listed in `image-animated-types'
|
||
and the number of sub-images in the image is more than one, then the
|
||
new function `create-animated-image' creates an animated image where
|
||
sub-images are displayed successively with the duration defined by
|
||
`image-animate-max-time' and the delay between sub-images defined
|
||
by the Graphic Control Extension of the image.
|
||
|
||
*** `image-extension-data' is renamed to `image-metadata'.
|
||
|
||
** XML and HTML parsing
|
||
|
||
*** If Emacs is compiled with libxml2 support (which is the default),
|
||
two new Emacs Lisp-level functions are defined:
|
||
`xml-parse-html-string-internal' (which will parse "real world" HTML)
|
||
and `xml-parse-string-internal' (which parses XML). Both return an
|
||
Emacs Lisp parse tree.
|
||
|
||
FIXME: These should be front-ended by xml.el.
|
||
|
||
** FIXME GnuTLS
|
||
|
||
** 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".
|
||
|
||
|
||
* Changes in Emacs 24.1 on non-free operating systems
|
||
|
||
** New configure.bat option --enable-checking builds emacs with extra
|
||
runtime checks.
|
||
|
||
** New configure.bat option --distfiles to specify files to be
|
||
included in binary distribution
|
||
|
||
** New make target `dist' to create binary disttribution for Windows
|
||
platform
