338648ad
GM
27** Configure links against libselinux if it is found.
28You can disable this by using --without-selinux.
29
30---
31** By default, the installed Info and man pages are compressed.
32You can disable this by configuring --without-compress-info.
33
aded53ff
GM
34---
35** There are new configure options:
36--with-mmdf, --with-mail-unlink, --with-mailhost.
37These provide no new functionality, they just remove the need to edit
38lib-src/Makefile by hand in order to use the associated features.
39
e547b051 40---
30c4d8dc 41** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
e547b051
J
42to configure. Note that other libraries used by Emacs, RSVG and GConf,
43also depend on Gtk+. You can disable them with --without-rsvg and
44--without-gconf.
45
d9170db5
DN
46** There is a new configure option --enable-use-lisp-union-type.
47This is only useful for Emacs developers to debug certain types of bugs.
b2957ea8 48This is not a new feature; only the configure flag is new.
d9170db5 49

EZ
50---
51** New translation of the Emacs Tutorial in Hebrew is available
52Type `C-u C-h t' to choose it in case your language setup doesn't
53automatically select it.

eb199145 56* Startup Changes in Emacs 24.1
4a263588 57
198a7a97 58** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
adbf62ff
GM
59command line arguments, and the EMACS_UNIBYTE environment variable, no
60longer have any effect. (They were declared obsolete in Emacs 23.)
198a7a97 61
66b7b0fe
GM
62** New command line option `--no-site-lisp' removes site-lisp directories
63from load-path. -Q now implies this.

eb199145 66* Changes in Emacs 24.1
7841339b 67
2a847524
CY
68** emacsclient changes
69
70*** New emacsclient argument --parent-id ID can be used to open a
0191e222
CY
71client frame in parent X window ID, via XEmbed. This works like the
72--parent-id argument to Emacs.
73
2a847524
CY
74*** If emacsclient shuts down as a result of Emacs signalling an
75error, its exit status is 1.
76
902a6d8d
SM
77** Completion can cycle, depending on completion-cycle-threshold.
78
2372f278
SM
79** auto-mode-case-fold is now enabled by default.
80
f4b6ba46
EZ
81+++
82** Emacs now supports display and editing of bidirectional text.
f4b6ba46
EZ
83
84See the node "Bidirectional Editing" in the Emacs Manual for some
85initial documentation.
86
87To turn this on in any given buffer, set the buffer-local variable
88`bidi-display-reordering' to a non-nil value. The default is nil.
89
90The buffer-local variable `bidi-paragraph-direction', if non-nil,
91forces each paragraph in the buffer to have its base direction
92according to the value of this variable. Possible values are
93`right-to-left' and `left-to-right'. If the value is nil (the
94default), Emacs determines the base direction of each paragraph from
95its text, as specified by the Unicode Bidirectional Algorithm.
96
d20e1419
EZ
97The function `current-bidi-paragraph-direction' returns the actual
98value of paragraph base direction at point.
99
f4b6ba46
EZ
100Reordering of bidirectional text for display in Emacs is a "Full
101bidirectionality" class implementation of the Unicode Bidirectional
102Algorithm.
103
46759717
EZ
104Note that some advanced display features, such as overlay strings and
105`display' text properties, do not yet work correctly when
106bidirectional text is reordered for display.
107
303500aa 108** GTK scroll-bars are now placed on the right by default.
52834b6b
CY
109Use `set-scroll-bar-mode' to change this.
110
20fe03ad 111** GTK tool bars can have just text, just images or images and text.
d8004abe 112Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
20fe03ad
JD
113is taken from the desktop settings.
114
8b2dd508
JD
115** GTK tool bars can be placed on the left/right or top/bottom of the frame.
116The frame-parameter tool-bar-position controls this. It takes the values
1c0d77cc 117top, left, right or bottom. The Options => Show/Hide menu has entries
8b2dd508
JD
118for this.
119
8740c12d 120** ImageMagick support.
b2fa3a09
GM
121It is now possible to use the ImageMagick library to load many new
122image formats in Emacs. By default, Emacs links with the ImageMagick
123libraries if they are present at build time. To disable this, use
8ea189f7 124the configure option `--without-imagemagick'.
16a91140 125
8740c12d
GM
126The new function `imagemagick-types' returns a list of image file
127extensions that your installation of ImageMagick supports. The
128function `imagemagick-register-types' enables ImageMagick support for
b2957ea8 129these image types, minus those listed in `imagemagick-types-inhibit'.
16a91140 130
8740c12d 131See the Emacs Lisp Reference Manual for more information.
16a91140 132
3a46642b
J
133** The colors for selected text (the region face) are taken from the GTK
134theme when Emacs is built with GTK.
135
aa1859f5
J
136** Emacs uses GTK tooltips by default if built with GTK. You can turn that
137off by customizing x-gtk-use-system-tooltips.
138
1ecb2d3f 139** Lucid menus and dialogs can display antialiased fonts if Emacs is built
a6ac7fc4
JD
140with Xft. To change font, use X resource faceName, for example:
141Emacs.pane.menubar.faceName: Courier-12
142Set faceName to none and use font to use the old X fonts.
99852628 143
0eb025fb
EZ
144+++
145** Enhanced support for characters that have no glyphs in available fonts
146If a character has no glyphs in any of the available fonts, Emacs by
147default will display it either as a hexadecimal code in a box or as a
148thin 1-pixel space. In addition to these two methods, Emacs can
149display these characters as empty box, as an acronym, or not display
150them at all. To change how these characters are displayed, customize
151the variable `glyphless-char-display-control'.
152
153On character terminals these methods are used for characters that
154cannot be encoded by the `terminal-coding-system'.
155
917794d5
CY
156** On graphical displays, the mode-line no longer ends in dashes.
157
b7d65a5f
GM
158** Basic SELinux support has been added.
159This requires Emacs to be linked with libselinux at build time.
160
d8004abe
GM
161*** Emacs preserves the SELinux file context when backing up, and
162optionally when copying files. To this end, copy-file has an extra
163optional argument, and backup-buffer and friends include the SELinux
164context in their return values.
b7d65a5f
GM
165
166*** The new functions file-selinux-context and set-file-selinux-context
167get and set the SELinux context of a file.
168
a5bee597
MA
169*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
170for remote machines which support SELinux.
171
9c524fcb 172** The function kill-emacs is now run upon receipt of the signals SIGTERM
383ebd15 173and SIGHUP, and upon SIGINT in batch mode.
9c524fcb
GM
174
175** kill-emacs-hook is now also run in batch mode.
176
79ce172a 177** New scrolling commands `scroll-up-command' and `scroll-down-command'
7b05466f
JL
178(bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
179of buffer at first key-press (instead moves to top/bottom of buffer)
180when a new variable `scroll-error-top-bottom' is non-nil.
79ce172a 181
5a97d2da
JL
182** New scrolling commands `scroll-up-line' and `scroll-down-line'
183scroll a line instead of full screen.
184
a4b000fb 185** New property `scroll-command' should be set on a command's symbol to
b2957ea8 186define it as a scroll command affected by `scroll-preserve-screen-position'.
9013a7f8 187
f1a5d776
CY
188** Trash changes
189
190*** `delete-by-moving-to-trash' now only affects commands that specify
191trashing. This avoids inadvertently trashing temporary files.
192
193*** Calling `delete-file' or `delete-directory' with a prefix argument
194now forces true deletion, regardless of `delete-by-moving-to-trash'.
195
f0bf7c8e
JL
196** New option `list-colors-sort' defines the color sort order
197for `list-colors-display'.
198
44198b6e
CY
199** An Emacs Lisp package manager is now included.
200This is a convenient way to download and install additional packages,
42d9cffa 201from a package repository at elpa.gnu.org.
cb6c4991
CY
202
203*** `M-x list-packages' shows a list of packages, which can be
204selected for installation.
205
206*** New command `describe-package', bound to `C-h P'.
44198b6e
CY
207
208*** By default, all installed packages are loaded and activated
209automatically when Emacs starts up. To disable this, set
210`package-enable-at-startup' to nil. To change which packages are
211loaded, customize `package-load-list'.
212
f065864f
CY
213** Custom Themes
214
215*** `M-x customize-themes' lists Custom themes which can be enabled.
216
782b5e8d
CY
217*** New option `custom-theme-load-path' is the load path for themes.
218Emacs no longer looks for custom themes in `load-path'. The default
219is to search in `custom-theme-directory', followed by a built-in theme
220directory named "themes/" in `data-directory'.
221
278f6845
CY
222*** New option `custom-safe-theme-files' lists known-safe theme files.
223If a theme is not in this list, Emacs queries before loading it.
224The default value treats all themes included in Emacs as safe.
225
4ddf410a
MA
226** The user option `remote-file-name-inhibit-cache' controls whether
227the remote file-name cache is used for read access.
228
17284e30
GM
229** The standalone programs lib-src/digest-doc and sorted-doc have been
230replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.
231
f13183cf
CY
232** The variable `focus-follows-mouse' now always defaults to nil.
233
0bfd685e 234\f
eb199145 235* Editing Changes in Emacs 24.1
b350bdf2 236
ea4f7750
GM
237+++
238** There is a new command `count-words-region', which does what you expect.
239
67027b49 240** completion-at-point now handles tags and semantic completion.
a982c7ec 241
d74cba8f
MA
242** The default value of `backup-by-copying-when-mismatch' is now t.
243
1c708c1a
CY
244** The command `just-one-space' (C-SPC), if given a negative argument,
245also deletes newlines around point.
246
b9229673
CY
247** Deletion changes
248
249*** New option `delete-active-region'.
250If non-nil, C-d, [delete], and DEL delete the region if it is active
251and no prefix argument is given. If set to `kill', these commands
252kill instead.
253
254*** New command `delete-forward-char', bound to C-d and [delete].
42d9cffa
CY
255This is meant for interactive use, and obeys `delete-active-region'.
256The command `delete-char' does not obey `delete-active-region'.
b9229673
CY
257
258*** `delete-backward-char' is now a Lisp function.
259Apart from obeying `delete-active-region', its behavior is unchanged.
260However, the byte compiler now warns if it is called from Lisp; you
261should use delete-char with a negative argument instead.
262
263*** The option `mouse-region-delete-keys' has been deleted.
264
f9d71b42
CY
265** Selection changes.
266
7c23dd44 267The default handling of clipboard and primary selections has been
42d9cffa
CY
268changed to conform with other X applications. The exact changes are
269described below; in short, mouse commands to select and paste text now
270use the primary selection, while all other commands for killing and
271yanking text now use the clipboard.
7c23dd44 272
42d9cffa
CY
273*** Merely selecting text (e.g. with drag-mouse-1) does not add it to
274the kill-ring. On systems with a primary selection separate from the
275clipboard (such as X), the selected text is put in the primary
276selection.
277
278*** mouse-2 is now bound to `mouse-yank-primary', which pastes from
279the primary selection regardless of the contents of the kill-ring.
280
281*** Commands that kill text or copy it to the kill-ring (M-w, C-w,
282C-k, etc.) also put the killed text into the clipboard. This change
283also means that the "Copy", "Cut", and "Paste" items in the "Edit"
284menu are now exactly equivalent to, respectively M-w, C-w, and C-y.
285
286*** Yank commands, such as C-y and M-y, retrieve text from the
287clipboard if it is available.
288
289*** The above changes are reflected in the following new defaults:
290
291**** `select-active-regions' now defaults to t.
d1b08c88 292It also accepts a new value, `only', which means to only set the
7c23dd44
CY
293primary selection for temporarily active regions (usually made by
294mouse-dragging or shift-selection).
295
42d9cffa 296**** `mouse-2' is now bound to `mouse-yank-primary'.
7c9b11be 297Previously, it was bound to `mouse-yank-at-click' (which is now
4c0f50c9 298unbound by default).
f9d71b42 299
42d9cffa
CY
300**** `x-select-enable-clipboard' now defaults to t on all platforms.
301Note that this variable was already non-nil by default on MS-Windows,
302which does not support the primary selection between applications.
f9d71b42 303
42d9cffa 304**** `x-select-enable-primary' now defaults to nil.
7c9b11be
EZ
305This variable exists only on X; its default value was t in previous
306versions.
2490cbbc 307
42d9cffa
CY
308**** `mouse-drag-copy-region' now defaults to nil.
309
310*** To return to the previous behavior, where mouse commands use the
311clipboard, change `mouse-drag-copy-region' and (on X only)
312`x-select-enable-primary' to t. If you don't want Emacs to put the
313text into the clipboard, only to the primary selection, additionally
314set `x-select-enable-clipboard' to nil.
f9d71b42 315
084e6df3
JD
316*** Support for X cut buffers has been removed.
317
99f053cf
JA
318** New command `rectangle-number-lines', bound to `C-x r N', numbers
319the lines in the current rectangle. With an prefix argument, this
320prompts for a number to count from and for a format string.
321
9bae34bf 322\f
eb199145 323* Changes in Specialized Modes and Packages in Emacs 24.1
efeb796b 324
78835dd0
SM
325** shell-mode can track your cwd by reading it from your prompt.
326Just set shell-dir-cookie-re to an appropriate regexp.
327
cbf83ce9
SM
328** Modula-2 mode provides auto-indentation.
329
b879a6e2
SM
330** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
331
360ac530 332** FIXME: xdg-open for browse-url and reportbug, 2010/08.
0ac3effe 333
b3671a51
JL
334** Archive Mode has basic support to browse 7z archives.
335
876d1684
LMI
336** browse-url has gotten a new variable that is used for mailto: URLs,
337 `browse-url-mailto-function', which defaults to `browse-url-mail'.
338
8a8d54cd
VD
339** ERC changes
340
341*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
342If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
343successful NickServ identification, or after `erc-autojoin-delay'
344seconds. The default value, 'ident, means to autojoin immediately
345after connecting.
346
5c0c0f77
LMI
347*** New variable `erc-coding-system-precedence': If we use `undecided'
348as the server coding system, this variable will then be consulted.
349The default is to decode strings that can be decoded as utf-8 as
350utf-8, and do the normal `undecided' decoding for the rest.
351
c0e505e5
CY
352** Eshell changes
353
354*** The default value of eshell-directory-name is a directory named
355"eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory
356exists, that is used instead.
357
27d3cd56
CY
358** In ido-mode, C-v is no longer bound to ido-toggle-vc.
359The reason is that this interferes with cua-mode.
360
c1e25821 361** partial-completion-mode is now obsolete.
79ccd68f
SM
362You can get a comparable behavior with:
363(setq completion-styles '(partial-completion initials))
364(setq completion-pcm-complete-word-inserts-delimiters t)
c1e25821 365
18c812bd 366** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
b2957ea8 367
1d83b0e9
GM
368** server can listen on a specific port using the server-port option.
369
cf16af42
GM
370** Calendar, Diary, and Appt
371
372---
373*** The obsolete (since Emacs 22.1) method of enabling the appt package
374by adding appt-make-list to diary-hook has been removed. Use appt-activate.
375
376---
377*** Some appt variables (obsolete since Emacs 22.1) have been removed:
378appt-issue-message (use the function appt-activate)
379appt-visible/appt-msg-window (use the variable appt-display-format)
380
381---
382*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
383view-diary-entries, list-diary-entries, show-all-diary-entries
384
52834b6b
CY
385** Customize
386
387*** Customize buffers now contain a search field.
388The search is performed using `customize-apropos'.
42d9cffa 389To turn off the search field, set custom-search-field to nil.
52834b6b
CY
390
391*** Custom options now start out hidden if at their default values.
392Use the arrow to the left of the option name to toggle visibility.
393
394*** custom-buffer-sort-alphabetically now defaults to t.
395
396*** The color widget now has a "Choose" button, which allows you to
397choose a color via list-colors-display.
398
f5d6548a
JL
399** Dired-x
400
401*** dired-jump and dired-jump-other-window called with a prefix argument
402read a file name from the minibuffer instead of using buffer-file-name.
403
8117868f
DN
404** Directory local variables can apply to file-less buffers.
405For example, adding "(diff-mode . ((mode . whitespace)))" to your
d8004abe 406.dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers.
8117868f 407
7492acc9
MM
408** SQL Mode enhancements.
409
30c4d8dc
MM
410*** Several variables have been marked as safe local variables. The
411variables `sql-product', `sql-user', `sql-server', `sql-database' and
412`sql-port' can now be safely used as local variables.
7492acc9 413
9250002f
MM
414*** `sql-dialect' is a synonym for `sql-product'.
415
74790210 416*** Added ability to login with a port on MySQL and Postgres.
7492acc9 417The custom variable `sql-port' can be specified for connection to
74790210
MM
418MySQL or Postgres servers. By default, the port is not listed in
419either login parameter, but will be added to the command line if set
420to a non-zero value.
7492acc9 421
9250002f
MM
422*** Dynamic selection of product in an SQL interactive session.
423If you use `sql-product-interactive' to start an SQL interactive
424session it uses the current value of `sql-product'. Preceding the
425invocation with C-u will force it to ask for the product before
426creating the session.
427
428*** Renaming a SQL interactive buffer when it is created.
429Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
430`sql-mysql', etc.) with C-u will force a new interactive session to be
431started and will prompt for the new name. This will reduce the need
432for `sql-rename-buffer' is most common use cases.
433

MM
434*** Command continuation prompts in SQL interactive mode are suppressed.
435Multiple line commands in SQL interactive mode, generate command
436continuation prompts which needlessly confuse the output. These
437prompts are now filtered out from the output. This change impacts
438multiple line SQL statements entered with C-j between each line,
439statements yanked into the buffer and statements sent with
440`sql-send-*' functions.
441
7492acc9
MM
442*** Custom variables control prompting for login parameters.
443Each supported product has a custom variable `sql-*-login-params'
444which is a list of the parameters to be prompted for before a
445connection is established.
446
74790210
MM
447The lists consist of the following five tokens: `user', `password',
448`database', `server', and `port'. The order in which they appear is
449the order in which they are prompted. The tokens symbols can be
450replaced by a sublist starting with the token and followed by a plist
451which control the prompting for values. The tokens `user',
452`database', and `server' each can take a property of :default which
453specifies the value to be used if no value is entered. The
454`database', `server', and `port' tokens handle the :completion
455property which restricts the entry to either one of the values in the
456list or to one of the values returned by the function provided as the
457property value. The `database' and `server' tokens also accept the
458:file property whose value is a regexp to identify useful file names.
459
460 (user :default DEF)
461 (database :default DEF
462 :file FILEPAT
463 :completion COMPLETE)
464 (server :default DEF
465 :file FILEPAT
466 :completion COMPLETE)
467
468The FILEPAT when :file is specified is a regexp that will match valid
469file names (without the directory portion). Generally these strings
470will be of the form ".+\.SUF" where SUF is the desired file suffix.
471
472When :completion is specified, the COMPLETE corresponds to the
473PREDICATE argument to the `completing-read' function (a list of
474possible values or a function returning such a list).
5474c40f 475
30c4d8dc
MM
476*** Added `sql-connection-alist' to record login parameter values.
477An alist for recording different username, database and server
478values. If there are multiple databases that you connect to the
479parameters needed can be stored in this alist.
480
481For example, the following might be set in the user's init.el:
482
483 (setq sql-connection-alist
484 '((dev (sql-product 'sqlite)
485 (sql-database "/home/mmaug/dev.db"))
486 (prd (sql-product 'oracle)
487 (sql-user "mmaug")
488 (sql-database "iprd2a"))))
489
490This defines two connections named "dev" and "prd".
491
492*** Added `sql-connect' to use predefined connections.
493Sets the login parameters based on the values in the
494`sql-connection-alist' and start a SQL interactive session. Any
495values specified in the connection will not be prompted for.
496
497In the example above, if the user were to invoke M-x sql-connect, they
498would be prompted for the connection. The user can respond with
499either "dev" or "prd". The "dev" connection would connect to the
500SQLite database without prompting; the "prd" connection would prompt
501for the users password and then connect to the Oracle database.
502
d26b0ea9 503**** Added SQL->Start... submenu when connections are defined.
b2957ea8 504When connections have been defined, there is a submenu available that
d26b0ea9
MM
505allows the user to select one to start a SQLi session. The "Start
506SQLi Session" item moves to the "Start..." submenu when cnnections
507have been defined.
508
509**** Added "Save Connection" menu item in SQLi buffers.
510When a SQLi session is not started by a connection then
511`sql-save-connection' will gather the login params specified for the
512session and save them as a new connection.
513
74790210
MM
514*** List database objects and details.
515Once a SQL interactive session has been started, you can get a list of
516the objects in the database and see details of those objects. The
517objects shown and the details available are product specific.
518
519**** List all objects.
520Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
521objects" will list all the objects in the database. At a minimum it
522lists the tables and views in the database. Preceeding the command by
523universal argument may provide additional details or extend the
524listing to include other schemas objects. The list will appear in a
525separate window in view-mode.
526
527**** List Table details.
528Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
529details" will ask for the name of a database table or view and display
530the list of columns in the relation. Preceeding the comand with the
531universal argument may provide additional details about each column.
532The list will appear in a separate window in view-mode.
533
7492acc9
MM
534*** Added option `sql-send-terminator'.
535When set makes sure that each command sent with `sql-send-*' commands
536are properly terminated and submitted to the SQL processor.
537
538*** Added option `sql-oracle-scan-on'.
539When set commands sent to Oracle's SQL*Plus are scanned for strings
30c4d8dc
MM
540starting with an ampersand and the user is asked for replacement text.
541In general, the SQL*Plus option SCAN should always be set OFF under
542SQL interactive mode and this option used in its place.
7492acc9
MM
543
544*** SQL interactive mode will replace tabs with spaces.
545This prevents the comand interpretter for MySQL and Postgres from
546listing object name completions when being sent text via
547`sql-send-*' functions.
548
549*** An API for manipulating SQL product definitions has been added.

579The vc-update command now runs a "pull" operation, if it is supported.
580This updates the current branch from upstream. A prefix argument
581means to prompt the user for command specifics, e.g. a pull location.
582
583**** vc-pull is an alias for vc-update.
584
585**** Currently supported by Bzr.
586
587*** Support for merging on distributed version control systems.
588The vc-merge command now runs a "merge" operation, if it is supported.
589This merges another branch into the current one. A prefix argument
590means to prompt the user for command specifics, e.g. a merge location.

633checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to
634determine whether to create a menu-bar or tool-bar, respectively.
635If the alist entries are added, they override the value of

682just call syntax-propertize to make sure the text is propertized.
683Together with this new variable come a new hook
684syntax-propertize-extend-region-functions, as well as two helper functions:
685syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
