7 If possible, use M-x report-emacs-bug.
9 This file is about changes in Emacs version 24.
11 See files NEWS.23, NEWS.22, NEWS.21, NEWS.20, NEWS.19, NEWS.18,
12 and NEWS.1-17 for changes in older Emacs versions.
14 You can narrow news to a specific version by calling `view-emacs-news'
15 with a prefix argument or by typing C-u C-h C-n.
19 +++ indicates that the appropriate manual has already been updated.
20 --- means no change in the manuals is called for.
21 When you add a new item, please add it without either +++ or ---
22 so we will look at it and add it to the manual.
25 * Installation Changes in Emacs 24.1
27 ** Configure links against libselinux if it is found.
28 You can disable this by using --without-selinux.
31 ** By default, the installed Info and man pages are compressed.
32 You can disable this by configuring --without-compress-info.
35 ** There are new configure options:
36 --with-mmdf, --with-mail-unlink, --with-mailhost.
37 These provide no new functionality, they just remove the need to edit
38 lib-src/Makefile by hand in order to use the associated features.
41 ** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
42 to configure. Note that other libraries used by Emacs, RSVG and GConf,
43 also depend on Gtk+. You can disable them with --without-rsvg and
46 ** There is a new configure option --enable-use-lisp-union-type.
47 This is only useful for Emacs developers to debug certain types of bugs.
48 This is not a new feature; only the configure flag is new.
51 ** New translation of the Emacs Tutorial in Hebrew is available
52 Type `C-u C-h t' to choose it in case your language setup doesn't
53 automatically select it.
56 * Startup Changes in Emacs 24.1
58 ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
59 command line arguments, and the EMACS_UNIBYTE environment variable, no
60 longer have any effect. (They were declared obsolete in Emacs 23.)
62 ** New command line option `--no-site-lisp' removes site-lisp directories
63 from load-path. -Q now implies this.
65 ** On Windows, Emacs now warns when the obsolete _emacs init file is used.
68 * Changes in Emacs 24.1
70 ** Completion in a non-minibuffer now tries to detect the end of completion
71 and pops down the *Completions* buffer accordingly.
73 ** emacsclient changes
75 *** New emacsclient argument --parent-id ID can be used to open a
76 client frame in parent X window ID, via XEmbed. This works like the
77 --parent-id argument to Emacs.
80 *** New emacsclient argument -q/--quiet suppresses some status messages.
82 *** If emacsclient shuts down as a result of Emacs signalling an
83 error, its exit status is 1.
85 ** Completion can cycle, depending on completion-cycle-threshold.
87 ** `completing-read' can be customized using the new variable
88 `completing-read-function'
90 ** auto-mode-case-fold is now enabled by default.
93 ** Emacs now supports display and editing of bidirectional text.
95 See the node "Bidirectional Editing" in the Emacs Manual for some
96 initial documentation.
98 To turn this on in any given buffer, set the buffer-local variable
99 `bidi-display-reordering' to a non-nil value. The default is nil.
101 The buffer-local variable `bidi-paragraph-direction', if non-nil,
102 forces each paragraph in the buffer to have its base direction
103 according to the value of this variable. Possible values are
104 `right-to-left' and `left-to-right'. If the value is nil (the
105 default), Emacs determines the base direction of each paragraph from
106 its text, as specified by the Unicode Bidirectional Algorithm.
108 The function `current-bidi-paragraph-direction' returns the actual
109 value of paragraph base direction at point.
111 Reordering of bidirectional text for display in Emacs is a "Full
112 bidirectionality" class implementation of the Unicode Bidirectional
115 Note that some advanced display features, such as overlay strings and
116 `display' text properties, do not yet work correctly when
117 bidirectional text is reordered for display.
119 ** GTK scroll-bars are now placed on the right by default.
120 Use `set-scroll-bar-mode' to change this.
122 ** GTK tool bars can have just text, just images or images and text.
123 Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
124 is taken from the desktop settings.
126 ** GTK tool bars can be placed on the left/right or top/bottom of the frame.
127 The frame-parameter tool-bar-position controls this. It takes the values
128 top, left, right or bottom. The Options => Show/Hide menu has entries
131 ** ImageMagick support.
132 It is now possible to use the ImageMagick library to load many new
133 image formats in Emacs. By default, Emacs links with the ImageMagick
134 libraries if they are present at build time. To disable this, use
135 the configure option `--without-imagemagick'.
137 The new function `imagemagick-types' returns a list of image file
138 extensions that your installation of ImageMagick supports. The
139 function `imagemagick-register-types' enables ImageMagick support for
140 these image types, minus those listed in `imagemagick-types-inhibit'.
142 See the Emacs Lisp Reference Manual for more information.
144 ** The colors for selected text (the region face) are taken from the GTK
145 theme when Emacs is built with GTK.
147 ** Emacs uses GTK tooltips by default if built with GTK. You can turn that
148 off by customizing x-gtk-use-system-tooltips.
150 ** Lucid menus and dialogs can display antialiased fonts if Emacs is built
151 with Xft. To change font, use the X resource font, for example:
152 Emacs.pane.menubar.font: Courier-12
155 ** Enhanced support for characters that have no glyphs in available fonts
156 If a character has no glyphs in any of the available fonts, Emacs by
157 default will display it either as a hexadecimal code in a box or as a
158 thin 1-pixel space. In addition to these two methods, Emacs can
159 display these characters as empty box, as an acronym, or not display
160 them at all. To change how these characters are displayed, customize
161 the variable `glyphless-char-display-control'.
163 On character terminals these methods are used for characters that
164 cannot be encoded by the `terminal-coding-system'.
166 ** On graphical displays, the mode-line no longer ends in dashes.
168 ** On Nextstep/OSX, the menu bar can be hidden by customizing
169 ns-auto-hide-menu-bar.
171 ** Basic SELinux support has been added.
172 This requires Emacs to be linked with libselinux at build time.
174 *** Emacs preserves the SELinux file context when backing up, and
175 optionally when copying files. To this end, copy-file has an extra
176 optional argument, and backup-buffer and friends include the SELinux
177 context in their return values.
179 *** The new functions file-selinux-context and set-file-selinux-context
180 get and set the SELinux context of a file.
182 *** Tramp offers handlers for file-selinux-context and set-file-selinux-context
183 for remote machines which support SELinux.
186 ** The function format-time-string now supports the %N directive, for
187 higher-resolution time stamps.
189 ** The function kill-emacs is now run upon receipt of the signals SIGTERM
190 and SIGHUP, and upon SIGINT in batch mode.
192 ** kill-emacs-hook is now also run in batch mode.
193 If you have code that adds something to kill-emacs-hook, you should
194 consider if it is still appropriate to add it in the noninteractive case.
196 ** New scrolling commands `scroll-up-command' and `scroll-down-command'
197 (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom
198 of buffer at first key-press (instead move to top/bottom of buffer)
199 when a new variable `scroll-error-top-bottom' is non-nil.
201 ** New scrolling commands `scroll-up-line' and `scroll-down-line'
202 scroll a line instead of full screen.
204 ** New property `scroll-command' should be set on a command's symbol to
205 define it as a scroll command affected by `scroll-preserve-screen-position'.
209 *** `delete-by-moving-to-trash' now only affects commands that specify
210 trashing. This avoids inadvertently trashing temporary files.
212 *** Calling `delete-file' or `delete-directory' with a prefix argument
213 now forces true deletion, regardless of `delete-by-moving-to-trash'.
215 ** New option `list-colors-sort' defines the color sort order
216 for `list-colors-display'.
218 ** An Emacs Lisp package manager is now included.
219 This is a convenient way to download and install additional packages,
220 from a package repository at elpa.gnu.org.
222 *** `M-x list-packages' shows a list of packages, which can be
223 selected for installation.
225 *** New command `describe-package', bound to `C-h P'.
227 *** By default, all installed packages are loaded and activated
228 automatically when Emacs starts up. To disable this, set
229 `package-enable-at-startup' to nil. To change which packages are
230 loaded, customize `package-load-list'.
232 ** An Emacs Lisp testing tool is now included.
233 Emacs Lisp developers can use this tool to write automated tests for
234 their code. See the ERT info manual for details.
238 *** `M-x customize-themes' lists Custom themes which can be enabled.
240 *** New option `custom-theme-load-path' is the load path for themes.
241 Emacs no longer looks for custom themes in `load-path'. The default
242 is to search in `custom-theme-directory', followed by a built-in theme
243 directory named "themes/" in `data-directory'.
245 *** New option `custom-safe-themes' records known-safe theme files.
246 If a theme is not in this list, Emacs queries before loading it, and
247 offers to save the theme to `custom-safe-themes' automatically. By
248 default, all themes included in Emacs are treated as safe.
250 ** The user option `remote-file-name-inhibit-cache' controls whether
251 the remote file-name cache is used for read access.
253 ** The standalone programs lib-src/digest-doc and sorted-doc have been
254 replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.
256 ** The variable `focus-follows-mouse' now always defaults to nil.
259 * Editing Changes in Emacs 24.1
264 *** C-y in Isearch is now bound to isearch-yank-kill, instead of
268 *** M-s C-e in Isearch is now bound to isearch-yank-line.
271 ** There is a new command `count-words-region', which does what you expect.
273 ** completion-at-point now handles tags and semantic completion.
275 ** The default value of `backup-by-copying-when-mismatch' is now t.
277 ** The command `just-one-space' (C-SPC), if given a negative argument,
278 also deletes newlines around point.
282 *** New option `delete-active-region'.
283 If non-nil, C-d, [delete], and DEL delete the region if it is active
284 and no prefix argument is given. If set to `kill', these commands
287 *** New command `delete-forward-char', bound to C-d and [delete].
288 This is meant for interactive use, and obeys `delete-active-region'.
289 The command `delete-char' does not obey `delete-active-region'.
291 *** `delete-backward-char' is now a Lisp function.
292 Apart from obeying `delete-active-region', its behavior is unchanged.
293 However, the byte compiler now warns if it is called from Lisp; you
294 should use delete-char with a negative argument instead.
296 *** The option `mouse-region-delete-keys' has been deleted.
298 ** Selection changes.
300 The default handling of clipboard and primary selections was changed
301 to conform with modern X applications. In short, most commands for
302 killing and yanking text now use the clipboard, while mouse commands
303 use the primary selection.
305 In the following, we provide a list of these changes, followed by a
306 list of steps to get the old behavior back if you prefer that.
308 *** `mouse-drag-copy-region' now defaults to nil.
309 *** `select-active-regions' now defaults to t.
310 Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
311 the kill-ring. The selected text is put in the primary selection, if
312 the system possesses a separate primary selection facility (e.g. X).
314 **** `select-active-regions' also accepts a new value, `only'.
315 This means to only set the primary selection for temporarily active
316 regions (usually made by mouse-dragging or shift-selection);
317 "ordinary" active regions, such as those made with C-SPC followed by
318 point motion, do not alter the primary selection.
320 *** mouse-2 is now bound to `mouse-yank-primary'.
321 This pastes from the primary selection, ignoring the kill-ring.
322 Previously, mouse-2 was bound to `mouse-yank-at-click'.
324 *** `x-select-enable-clipboard' now defaults to t on all platforms.
325 *** `x-select-enable-primary' now defaults to nil.
326 Thus, commands that kill text or copy it to the kill-ring (such as
327 M-w, C-w, and C-k) also use the clipboard---not the primary selection.
329 **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
330 exactly equivalent to, respectively M-w, C-w, and C-y.
332 **** Note that on MS-Windows, `x-select-enable-clipboard' was already
333 non-nil by default, as Windows does not support the primary selection
334 between applications.
336 *** To return to the previous behavior, do the following:
338 **** Change `mouse-drag-copy-region' to t.
339 **** Change `x-select-enable-primary' to t (on X only).
340 **** Change `x-select-enable-clipboard' to nil.
341 **** Bind `mouse-yank-at-click' to mouse-2.
343 *** Support for X cut buffers has been removed.
345 ** New command `rectangle-number-lines', bound to `C-x r N', numbers
346 the lines in the current rectangle. With an prefix argument, this
347 prompts for a number to count from and for a format string.
349 ** The command shell prompts for the shell path name, when the default
350 directory is a remote file name and neither environment variable
351 $ESHELL nor variable `explicit-shell-file-name' is set.
354 * Changes in Specialized Modes and Packages in Emacs 24.1
356 ** The compile.el mode can be used without font-lock-mode.
357 `compilation-parse-errors-function' is now obsolete.
359 ** The Landmark game is now invoked with `landmark', not `lm'.
361 ** Prolog mode has been completely revamped, with lots of additional
362 functionality such as more intelligent indentation, electricity, support for
363 more variants, including Mercury, and a lot more.
365 ** shell-mode can track your cwd by reading it from your prompt.
366 Just set shell-dir-cookie-re to an appropriate regexp.
368 ** Modula-2 mode provides auto-indentation.
370 ** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
372 ** FIXME: xdg-open for browse-url and reportbug, 2010/08.
374 ** Archive Mode has basic support to browse 7z archives.
376 ** browse-url has gotten a new variable that is used for mailto: URLs,
377 `browse-url-mailto-function', which defaults to `browse-url-mail'.
379 ** Directory local variables can apply to file-less buffers, in certain modes
380 (eg dired, vc-dir, log-edit). For example, adding
381 "(diff-mode . ((mode . whitespace)))" to your .dir-locals.el file,
382 will turn on `whitespace-mode' for *vc-diff* buffers. Modes should
383 call `hack-dir-local-variables-non-file-buffer' to support this.
386 ** You can prevent directory local variables from applying to subdirectories.
387 Add an element (subdirs . nil) to the alist portion of any variables
388 settings to indicate said section should not be applied to subdirectories.
392 *** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
393 If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
394 successful NickServ identification, or after `erc-autojoin-delay'
395 seconds. The default value, 'ident, means to autojoin immediately
398 *** New variable `erc-coding-system-precedence': If we use `undecided'
399 as the server coding system, this variable will then be consulted.
400 The default is to decode strings that can be decoded as utf-8 as
401 utf-8, and do the normal `undecided' decoding for the rest.
405 *** The default value of eshell-directory-name is a directory named
406 "eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory
407 exists, that is used instead.
409 ** In ido-mode, C-v is no longer bound to ido-toggle-vc.
410 The reason is that this interferes with cua-mode.
412 ** partial-completion-mode is now obsolete.
413 You can get a comparable behavior with:
414 (setq completion-styles '(partial-completion initials))
415 (setq completion-pcm-complete-word-inserts-delimiters t)
417 ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
419 ** server can listen on a specific port using the server-port option.
421 ** Calendar, Diary, and Appt
423 *** New function `diary-hebrew-birthday'.
426 *** The obsolete (since Emacs 22.1) method of enabling the appt package
427 by adding appt-make-list to diary-hook has been removed. Use appt-activate.
430 *** Some appt variables (obsolete since Emacs 22.1) have been removed:
431 appt-issue-message (use the function appt-activate)
432 appt-visible/appt-msg-window (use the variable appt-display-format)
435 *** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
436 view-diary-entries, list-diary-entries, show-all-diary-entries
440 *** Customize buffers now contain a search field.
441 The search is performed using `customize-apropos'.
442 To turn off the search field, set custom-search-field to nil.
444 *** Custom options now start out hidden if at their default values.
445 Use the arrow to the left of the option name to toggle visibility.
447 *** custom-buffer-sort-alphabetically now defaults to t.
449 *** The color widget now has a "Choose" button, which allows you to
450 choose a color via list-colors-display.
454 *** dired-jump and dired-jump-other-window called with a prefix argument
455 read a file name from the minibuffer instead of using buffer-file-name.
458 *** The `dired local variables' feature provided by Dired-x is obsolete.
459 The standard directory local variables feature replaces it.
461 ** SQL Mode enhancements.
463 *** `sql-dialect' is a synonym for `sql-product'.
465 *** Added ability to login with a port on MySQL and Postgres.
466 The custom variable `sql-port' can be specified for connection to
467 MySQL or Postgres servers. By default, the port is not listed in
468 either login parameter, but will be added to the command line if set
471 *** Dynamic selection of product in an SQL interactive session.
472 If you use `sql-product-interactive' to start an SQL interactive
473 session it uses the current value of `sql-product'. Preceding the
474 invocation with C-u will force it to ask for the product before
475 creating the session.
477 *** Renaming a SQL interactive buffer when it is created.
478 Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
479 `sql-mysql', etc.) with C-u will force a new interactive session to be
480 started and will prompt for the new name. This will reduce the need
481 for `sql-rename-buffer' is most common use cases.
483 *** Command continuation prompts in SQL interactive mode are suppressed.
484 Multiple line commands in SQL interactive mode, generate command
485 continuation prompts which needlessly confuse the output. These
486 prompts are now filtered out from the output. This change impacts
487 multiple line SQL statements entered with C-j between each line,
488 statements yanked into the buffer and statements sent with
489 `sql-send-*' functions.
491 *** Custom variables control prompting for login parameters.
492 Each supported product has a custom variable `sql-*-login-params'
493 which is a list of the parameters to be prompted for before a
494 connection is established.
496 The lists consist of the following five tokens: `user', `password',
497 `database', `server', and `port'. The order in which they appear is
498 the order in which they are prompted. The tokens symbols can be
499 replaced by a sublist starting with the token and followed by a plist
500 which control the prompting for values. The tokens `user',
501 `database', and `server' each can take a property of :default which
502 specifies the value to be used if no value is entered. The
503 `database', `server', and `port' tokens handle the :completion
504 property which restricts the entry to either one of the values in the
505 list or to one of the values returned by the function provided as the
506 property value. The `database' and `server' tokens also accept the
507 :file property whose value is a regexp to identify useful file names.
510 (database :default DEF
512 :completion COMPLETE)
515 :completion COMPLETE)
517 The FILEPAT when :file is specified is a regexp that will match valid
518 file names (without the directory portion). Generally these strings
519 will be of the form ".+\.SUF" where SUF is the desired file suffix.
521 When :completion is specified, the COMPLETE corresponds to the
522 PREDICATE argument to the `completing-read' function (a list of
523 possible values or a function returning such a list).
525 *** Added `sql-connection-alist' to record login parameter values.
526 An alist for recording different username, database and server
527 values. If there are multiple databases that you connect to the
528 parameters needed can be stored in this alist.
530 For example, the following might be set in the user's init.el:
532 (setq sql-connection-alist
533 '((dev (sql-product 'sqlite)
534 (sql-database "/home/mmaug/dev.db"))
535 (prd (sql-product 'oracle)
537 (sql-database "iprd2a"))))
539 This defines two connections named "dev" and "prd".
541 *** Added `sql-connect' to use predefined connections.
542 Sets the login parameters based on the values in the
543 `sql-connection-alist' and start a SQL interactive session. Any
544 values specified in the connection will not be prompted for.
546 In the example above, if the user were to invoke M-x sql-connect, they
547 would be prompted for the connection. The user can respond with
548 either "dev" or "prd". The "dev" connection would connect to the
549 SQLite database without prompting; the "prd" connection would prompt
550 for the users password and then connect to the Oracle database.
552 **** Added SQL->Start... submenu when connections are defined.
553 When connections have been defined, there is a submenu available that
554 allows the user to select one to start a SQLi session. The "Start
555 SQLi Session" item moves to the "Start..." submenu when cnnections
558 **** Added "Save Connection" menu item in SQLi buffers.
559 When a SQLi session is not started by a connection then
560 `sql-save-connection' will gather the login params specified for the
561 session and save them as a new connection.
563 *** List database objects and details.
564 Once a SQL interactive session has been started, you can get a list of
565 the objects in the database and see details of those objects. The
566 objects shown and the details available are product specific.
568 **** List all objects.
569 Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
570 objects" will list all the objects in the database. At a minimum it
571 lists the tables and views in the database. Preceding the command by
572 universal argument may provide additional details or extend the
573 listing to include other schemas objects. The list will appear in a
574 separate window in view-mode.
576 **** List Table details.
577 Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
578 details" will ask for the name of a database table or view and display
579 the list of columns in the relation. Preceding the command with the
580 universal argument may provide additional details about each column.
581 The list will appear in a separate window in view-mode.
583 *** Added option `sql-send-terminator'.
584 When set makes sure that each command sent with `sql-send-*' commands
585 are properly terminated and submitted to the SQL processor.
587 *** Added option `sql-oracle-scan-on'.
588 When set commands sent to Oracle's SQL*Plus are scanned for strings
589 starting with an ampersand and the user is asked for replacement text.
590 In general, the SQL*Plus option SCAN should always be set OFF under
591 SQL interactive mode and this option used in its place.
593 *** SQL interactive mode will replace tabs with spaces.
594 This prevents the command interpreter for MySQL and Postgres from
595 listing object name completions when being sent text via
596 `sql-send-*' functions.
598 *** An API for manipulating SQL product definitions has been added.
600 ** sregex.el is now obsolete, since rx.el is a strict superset.
602 ** s-region.el and pc-select are now declared obsolete,
603 superseded by shift-select-mode enabled by default in 23.1.
604 ** pc-mode.el is also declared obsolete.
607 *** GDB User Interface migrated to GDB Machine Interface and now
608 supports multithread non-stop debugging and debugging of several
609 threads simultaneously.
613 *** It is possible now, to access alternative buses than the default
614 system or session bus.
616 *** dbus-register-{service,method,property}
617 The -method and -property functions do not automatically register
620 The new function dbus-register-service registers a service known name
621 on a D-Bus without simultaneously registering a property or a method.
625 *** There exists a new inline access method "ksu" (kerberized su).
627 *** The following access methods are discontinued: "ssh1_old",
628 "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish".
630 ** VC and related modes
632 *** Support for pulling on distributed version control systems.
633 The vc-pull command runs a "pull" operation, if it is supported.
634 This updates the current branch from upstream. A prefix argument
635 means to prompt the user for specifics, e.g. a pull location.
637 **** `vc-update' is now an alias for `vc-pull'.
639 **** Currently supported by Bzr, Git, and Mercurial.
641 *** Support for merging on distributed version control systems.
642 The vc-merge command now runs a "merge" operation, if it is supported.
643 This merges another branch into the current one. This command prompts
644 the user for specifics, e.g. a merge source.
646 **** Currently supported for Bzr, Git, and Mercurial.
648 *** Log entries in some Log View buffers can be toggled to display a
649 longer description by typing RET (log-view-toggle-entry-display).
650 In the Log View buffers made by `C-x v L' (vc-print-root-log), you can
651 use this to display the full log entry for the revision at point.
653 **** Currently supported for Bzr, Git, and Mercurial.
655 **** Packages using Log View mode can enable this functionality by
656 binding `log-view-expanded-log-entry-function' to a suitable function.
661 *** `copyright-fix-years' can optionally convert consecutive years to ranges.
663 *** New command `nato-region' converts text to NATO phonetic alphabet.
666 * New Modes and Packages in Emacs 24.1
668 ** New global minor modes electric-pair-mode, electric-indent-mode,
669 and electric-layout-mode.
671 ** pcase.el provides the ML-style pattern matching macro `pcase'.
673 ** secrets.el is an implementation of the Secret Service API, an
674 interface to password managers like GNOME Keyring or KDE Wallet. The
675 Secret Service API requires D-Bus for communication. The command
676 `secrets-show-secrets' offers a buffer with a visualization of the
679 ** notifications.el provides an implementation of the Desktop
680 Notifications API. It requires D-Bus for communication.
682 ** soap-client.el supports access to SOAP web services from Emacs.
683 soap-inspect.el is an interactive inspector for SOAP WSDL structures.
685 ** xmodmap-generic-mode for xmodmap files.
688 * Incompatible Lisp Changes in Emacs 24.1
690 ** `copy-directory' now copies the source directory as a subdirectory
691 of the target directory, if the latter is an existing directory. The
692 new optional arg COPY-CONTENTS, if non-nil, makes the function copy
693 the contents directly into a pre-existing target directory.
695 ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and
696 passes it to the mail user agent function. This argument specifies an
697 action for returning to the caller after finishing with the mail.
698 This is currently used by Rmail to delete a mail window.
700 ** For mouse click input events in the text area, the Y pixel
701 coordinate in the POSITION list now counts from the top of the text
702 area, excluding any header line. Previously, it counted from the top
705 ** Remove obsolete name `e' (use `float-e' instead).
707 ** A backquote not followed by a space is now always treated as new-style.
709 ** Test for special mode-class was moved from view-file to view-buffer.
710 FIXME: This only says what was changed, but not what are the
711 programmer-visible consequences.
713 ** Passing a nil argument to a minor mode function now turns the mode
716 ** During startup, Emacs no longer adds entries for `menu-bar-lines'
717 and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'.
718 With these alist entries omitted, `make-frame' checks the value of the
719 variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create
720 a menu-bar or tool-bar, respectively. If the alist entries are added,
721 they override the value of `menu-bar-mode'/`tool-bar-mode'.
723 ** Regions created by mouse dragging are now normal active regions,
724 similar to the ones created by shift-selection. In previous Emacs
725 versions, these regions were delineated by `mouse-drag-overlay', which
726 has now been removed.
728 ** cl.el no longer provides `cl-19'.
730 ** The following functions and aliases, obsolete since at least Emacs 21.1,
732 comint-kill-output, decompose-composite-char, outline-visible,
733 internal-find-face, internal-get-face, frame-update-faces,
734 frame-update-face-colors, x-frob-font-weight, x-frob-font-slant,
735 x-make-font-bold, x-make-font-demibold, x-make-font-unbold
736 x-make-font-italic, x-make-font-oblique, x-make-font-unitalic
737 x-make-font-bold-italic, mldrag-drag-mode-line, mldrag-drag-vertical-line,
738 iswitchb-default-keybindings, char-bytes, isearch-return-char,
741 ** The following variables and aliases, obsolete since at least Emacs 21.1,
743 checkdoc-minor-keymap, vc-header-alist, directory-sep-char,
744 font-lock-defaults-alist
746 ** The following files, obsolete since at least Emacs 21.1, have been removed:
747 sc.el, x-menu.el, rnews.el, rnewspost.el
749 ** FIXME finder-inf.el changes.
752 * Lisp changes in Emacs 24.1
754 ** pre/post-command-hook are not reset to nil upon error.
755 Instead, the offending function is removed.
757 ** New low-level function run-hook-wrapped.
759 ** byte-compile-disable-print-circle is obsolete.
760 ** deferred-action-list and deferred-action-function are obsolete.
761 ** Removed the stack-trace-on-error variable.
762 Also the debugger can now "continue" from an error, which means it will jump
763 to the error handler as if the debugger had not been invoked instead of
764 jumping all the way to the top-level.
766 ** New function `read-char-choice' reads a restricted set of characters,
767 discarding any inputs not inside the set.
769 ** `image-library-alist' is renamed to `dynamic-library-alist'.
770 The variable is now used to load all kind of supported dynamic libraries,
771 not just image libraries. The previous name is still available as an
774 ** New variable syntax-propertize-function to set syntax-table properties.
775 Replaces font-lock-syntactic-keywords which are now obsolete.
776 This allows syntax-table properties to be set independently from font-lock:
777 just call syntax-propertize to make sure the text is propertized.
778 Together with this new variable come a new hook
779 syntax-propertize-extend-region-functions, as well as two helper functions:
780 syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
781 as-is; and syntax-propertize-rules which provides a new way to specify
784 ** New hook post-self-insert-hook run at the end of self-insert-command.
787 ** Syntax tables support a new "comment style c" additionally to style b.
788 ** frame-local variables cannot be let-bound any more.
789 ** prog-mode is a new major-mode meant to be the parent of programming mode.
790 ** define-minor-mode accepts a new keyword :variable.
792 ** `delete-file' and `delete-directory' now accept optional arg TRASH.
793 Trashing is performed if TRASH and `delete-by-moving-to-trash' are
794 both non-nil. Interactively, TRASH defaults to t, unless a prefix
795 argument is supplied (see Trash changes, above).
797 ** buffer-substring-filters is obsoleted by filter-buffer-substring-functions.
799 ** New completion style `substring'.
801 ** `facemenu-read-color' is now an alias for `read-color'.
802 The command `read-color' now requires a match for a color name or RGB
803 triplet, instead of signalling an error if the user provides a invalid
806 ** Tool-bars can display separators.
807 Tool-bar separators are handled like menu separators in menu-bar maps,
808 i.e. via menu entries of the form `(menu-item "--")'.
812 *** When the image type is one of listed in `image-animated-types'
813 and the number of sub-images in the image is more than one, then the
814 new function `create-animated-image' creates an animated image where
815 sub-images are displayed successively with the duration defined by
816 `image-animate-max-time' and the delay between sub-images defined
817 by the Graphic Control Extension of the image.
819 *** `image-extension-data' is renamed to `image-metadata'.
821 ** XML and HTML parsing
823 *** If Emacs is compiled with libxml2 support (which is the default),
824 two new Emacs Lisp-level functions are defined:
825 `libxml-parse-html-region' (which will parse "real world" HTML)
826 and `libxml-parse-xml-region' (which parses XML). Both return an
827 Emacs Lisp parse tree.
829 FIXME: These should be front-ended by xml.el.
835 *** New hook `isearch-update-post-hook' that runs in `isearch-update'.
837 ** Progress reporters can now "spin".
838 The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
839 now be nil, or omitted. This makes a "non-numeric" reporter. Each
840 time you call `progress-reporter-update' on that progress reporter,
841 with a nil or omitted VALUE argument, the reporter message is
842 displayed with a "spinning bar".
845 * Changes in Emacs 24.1 on non-free operating systems
847 ** New configure.bat option --enable-checking builds Emacs with extra
850 ** New configure.bat option --distfiles to specify files to be
851 included in binary distribution.
853 ** New make target `dist' to create binary distribution for MS Windows.
