27 | ** Configure links against libselinux if it is found. |
28 | You can disable this by using --without-selinux. | |
29 | ||
30 | --- | |
31 | ** By default, the installed Info and man pages are compressed. | |
32 | You 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. | |
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. | |
39 | ||
1ddac986 GM |
40 | --- |
41 | ** There is a new configure option --with-crt-dir. | |
42 | This is only useful if your crt*.o files are in a non-standard location. | |
43 | ||
e547b051 | 44 | --- |
30c4d8dc | 45 | ** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
e547b051 J |
46 | to configure. Note that other libraries used by Emacs, RSVG and GConf, |
47 | also depend on Gtk+. You can disable them with --without-rsvg and | |
48 | --without-gconf. | |
49 | ||
d9170db5 DN |
50 | ** There is a new configure option --enable-use-lisp-union-type. |
51 | This is only useful for Emacs developers to debug certain types of bugs. | |
b2957ea8 | 52 | This is not a new feature; only the configure flag is new. |
d9170db5 | 53 | |

55 | ** New translation of the Emacs Tutorial in Hebrew is available | |
56 | Type `C-u C-h t' to choose it in case your language setup doesn't | |
57 | automatically select it. | |

198a7a97 CY |
62 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte |
63 | command line arguments no longer have any effect. (They were declared | |
64 | obsolete in Emacs 23.) | |

0191e222 CY |
69 | ** New emacsclient argument --parent-id ID can be used to open a |
70 | client frame in parent X window ID, via XEmbed. This works like the | |
71 | --parent-id argument to Emacs. | |
72 | ||
902a6d8d SM |
73 | ** Completion can cycle, depending on completion-cycle-threshold. |
74 | ||
2372f278 SM |
75 | ** auto-mode-case-fold is now enabled by default. |
76 | ||
f4b6ba46 EZ |
77 | +++ |
78 | ** Emacs now supports display and editing of bidirectional text. | |
f4b6ba46 EZ |
79 | |
80 | See the node "Bidirectional Editing" in the Emacs Manual for some | |
81 | initial documentation. | |
82 | ||
83 | To turn this on in any given buffer, set the buffer-local variable | |
84 | `bidi-display-reordering' to a non-nil value. The default is nil. | |
85 | ||
86 | The buffer-local variable `bidi-paragraph-direction', if non-nil, | |
87 | forces each paragraph in the buffer to have its base direction | |
88 | according to the value of this variable. Possible values are | |
89 | `right-to-left' and `left-to-right'. If the value is nil (the | |
90 | default), Emacs determines the base direction of each paragraph from | |
91 | its text, as specified by the Unicode Bidirectional Algorithm. | |
92 | ||
d20e1419 EZ |
93 | The function `current-bidi-paragraph-direction' returns the actual |
94 | value of paragraph base direction at point. | |
95 | ||
f4b6ba46 EZ |
96 | Reordering of bidirectional text for display in Emacs is a "Full |
97 | bidirectionality" class implementation of the Unicode Bidirectional | |
98 | Algorithm. | |
99 | ||
46759717 EZ |
100 | Note that some advanced display features, such as overlay strings and |
101 | `display' text properties, do not yet work correctly when | |
102 | bidirectional text is reordered for display. | |
103 | ||
303500aa | 104 | ** GTK scroll-bars are now placed on the right by default. |
52834b6b CY |
105 | Use `set-scroll-bar-mode' to change this. |
106 | ||
20fe03ad | 107 | ** GTK tool bars can have just text, just images or images and text. |
d8004abe | 108 | Customize `tool-bar-style' to choose style. On a Gnome desktop, the default |
20fe03ad JD |
109 | is taken from the desktop settings. |
110 | ||
8b2dd508 JD |
111 | ** GTK tool bars can be placed on the left/right or top/bottom of the frame. |
112 | The frame-parameter tool-bar-position controls this. It takes the values | |
1c0d77cc | 113 | top, left, right or bottom. The Options => Show/Hide menu has entries |
8b2dd508 JD |
114 | for this. |
115 | ||
8740c12d | 116 | ** ImageMagick support. |
b2fa3a09 GM |
117 | It is now possible to use the ImageMagick library to load many new |
118 | image formats in Emacs. By default, Emacs links with the ImageMagick | |
119 | libraries if they are present at build time. To disable this, use | |
8ea189f7 | 120 | the configure option `--without-imagemagick'. |
16a91140 | 121 | |
8740c12d GM |
122 | The new function `imagemagick-types' returns a list of image file |
123 | extensions that your installation of ImageMagick supports. The | |
124 | function `imagemagick-register-types' enables ImageMagick support for | |
b2957ea8 | 125 | these image types, minus those listed in `imagemagick-types-inhibit'. |
16a91140 | 126 | |
8740c12d | 127 | See the Emacs Lisp Reference Manual for more information. |
16a91140 | 128 | |
3a46642b J |
129 | ** The colors for selected text (the region face) are taken from the GTK |
130 | theme when Emacs is built with GTK. | |
131 | ||
aa1859f5 J |
132 | ** Emacs uses GTK tooltips by default if built with GTK. You can turn that |
133 | off by customizing x-gtk-use-system-tooltips. | |
134 | ||
1ecb2d3f JD |
135 | ** Lucid menus and dialogs can display antialiased fonts if Emacs is built |
136 | with Xft. | |
99852628 | 137 | |
b7d65a5f GM |
138 | ** Basic SELinux support has been added. |
139 | This requires Emacs to be linked with libselinux at build time. | |
140 | ||
d8004abe GM |
141 | *** Emacs preserves the SELinux file context when backing up, and |
142 | optionally when copying files. To this end, copy-file has an extra | |
143 | optional argument, and backup-buffer and friends include the SELinux | |
144 | context in their return values. | |
b7d65a5f GM |
145 | |
146 | *** The new functions file-selinux-context and set-file-selinux-context | |
147 | get and set the SELinux context of a file. | |
148 | ||
a5bee597 MA |
149 | *** Tramp offers handlers for file-selinux-context and set-file-selinux-context |
150 | for remote machines which support SELinux. | |
151 | ||
9c524fcb GM |
152 | ** The function kill-emacs is now run upon receipt of the signals SIGTERM |
153 | and SIGHUP, and (except on MS-Windows) SIGINT in batch mode. | |
154 | ||
155 | ** kill-emacs-hook is now also run in batch mode. | |
156 | ||
79ce172a | 157 | ** New scrolling commands `scroll-up-command' and `scroll-down-command' |
7b05466f JL |
158 | (bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom |
159 | of buffer at first key-press (instead moves to top/bottom of buffer) | |
160 | when a new variable `scroll-error-top-bottom' is non-nil. | |
79ce172a | 161 | |
5a97d2da JL |
162 | ** New scrolling commands `scroll-up-line' and `scroll-down-line' |
163 | scroll a line instead of full screen. | |
164 | ||
a4b000fb | 165 | ** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 166 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
9013a7f8 | 167 | |
f1a5d776 CY |
168 | ** Trash changes |
169 | ||
170 | *** `delete-by-moving-to-trash' now only affects commands that specify | |
171 | trashing. This avoids inadvertently trashing temporary files. | |
172 | ||
173 | *** Calling `delete-file' or `delete-directory' with a prefix argument | |
174 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
175 | ||
f0bf7c8e JL |
176 | ** New option `list-colors-sort' defines the color sort order |
177 | for `list-colors-display'. | |
178 | ||
44198b6e CY |
179 | ** An Emacs Lisp package manager is now included. |
180 | This is a convenient way to download and install additional packages, | |
cb6c4991 CY |
181 | from elpa.gnu.org. |
182 | ||
183 | *** `M-x list-packages' shows a list of packages, which can be | |
184 | selected for installation. | |
185 | ||
186 | *** New command `describe-package', bound to `C-h P'. | |
44198b6e CY |
187 | |
188 | *** By default, all installed packages are loaded and activated | |
189 | automatically when Emacs starts up. To disable this, set | |
190 | `package-enable-at-startup' to nil. To change which packages are | |
191 | loaded, customize `package-load-list'. | |

eb199145 | 194 | * Editing Changes in Emacs 24.1 |
b350bdf2 | 195 | |
a982c7ec CY |
196 | ** completion-at-point is now an alias for complete-symbol. |
197 | ||
b9229673 CY |
198 | ** Deletion changes |
199 | ||
200 | *** New option `delete-active-region'. | |
201 | If non-nil, C-d, [delete], and DEL delete the region if it is active | |
202 | and no prefix argument is given. If set to `kill', these commands | |
203 | kill instead. | |
204 | ||
205 | *** New command `delete-forward-char', bound to C-d and [delete]. | |
206 | This is meant for interactive use, and obeys `delete-active-region'; | |
207 | delete-char, meant for Lisp, does not obey `delete-active-region'. | |
208 | ||
209 | *** `delete-backward-char' is now a Lisp function. | |
210 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
211 | However, the byte compiler now warns if it is called from Lisp; you | |
212 | should use delete-char with a negative argument instead. | |
213 | ||
214 | *** The option `mouse-region-delete-keys' has been deleted. | |
215 | ||
f9d71b42 CY |
216 | ** Selection changes. |
217 | ||
7c23dd44 CY |
218 | The default handling of clipboard and primary selections has been |
219 | changed to conform with other X applications. | |
f9d71b42 | 220 | |
7c23dd44 CY |
221 | *** `select-active-regions' now defaults to t, so active regions set |
222 | the primary selection. | |
223 | ||
224 | It also accepts a new value, `lazy', which means to only set the | |
225 | primary selection for temporarily active regions (usually made by | |
226 | mouse-dragging or shift-selection). | |
227 | ||
228 | *** `mouse-2' is now bound to `mouse-yank-primary'. | |
f9d71b42 CY |
229 | |
230 | *** `x-select-enable-clipboard' now defaults to t. | |
7c23dd44 CY |
231 | Thus, killing and yanking now use the clipboard (in addition to the |
232 | kill ring). | |
f9d71b42 | 233 | |
2490cbbc CY |
234 | *** `x-select-enable-primary' now defaults to nil. |
235 | ||
f9d71b42 CY |
236 | *** `mouse-drag-copy-region' now defaults to nil. |
237 | ||
084e6df3 JD |
238 | *** Support for X cut buffers has been removed. |
239 | ||

eb199145 | 241 | * Changes in Specialized Modes and Packages in Emacs 24.1 |
efeb796b | 242 | |
b879a6e2 SM |
243 | ** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. |
244 | ||
3b083a0f | 245 | ** FIXME: xdg-open for browse-url and reportbug, 2010/08. (Close bug#4546?) |
0ac3effe | 246 | |
b3671a51 JL |
247 | ** Archive Mode has basic support to browse 7z archives. |
248 | ||
8a8d54cd VD |
249 | ** ERC changes |
250 | ||
251 | *** New vars `erc-autojoin-timing' and `erc-autojoin-delay'. | |
252 | If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a | |
253 | successful NickServ identification, or after `erc-autojoin-delay' | |
254 | seconds. The default value, 'ident, means to autojoin immediately | |
255 | after connecting. | |
256 | ||
27d3cd56 CY |
257 | ** In ido-mode, C-v is no longer bound to ido-toggle-vc. |
258 | The reason is that this interferes with cua-mode. | |
259 | ||
c1e25821 | 260 | ** partial-completion-mode is now obsolete. |
79ccd68f SM |
261 | You can get a comparable behavior with: |
262 | (setq completion-styles '(partial-completion initials)) | |
263 | (setq completion-pcm-complete-word-inserts-delimiters t) | |
c1e25821 | 264 | |
18c812bd | 265 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
b2957ea8 | 266 | |
cf16af42 GM |
267 | ** Calendar, Diary, and Appt |
268 | ||
269 | --- | |
270 | *** The obsolete (since Emacs 22.1) method of enabling the appt package | |
271 | by adding appt-make-list to diary-hook has been removed. Use appt-activate. | |
272 | ||
273 | --- | |
274 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: | |
275 | appt-issue-message (use the function appt-activate) | |
276 | appt-visible/appt-msg-window (use the variable appt-display-format) | |
277 | ||
278 | --- | |
279 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: | |
280 | view-diary-entries, list-diary-entries, show-all-diary-entries | |
281 | ||
52834b6b CY |
282 | ** Customize |
283 | ||
284 | *** Customize buffers now contain a search field. | |
285 | The search is performed using `customize-apropos'. | |
286 | To turn off the search field, set custom-search-field to nil . | |
287 | ||
288 | *** Custom options now start out hidden if at their default values. | |
289 | Use the arrow to the left of the option name to toggle visibility. | |
290 | ||
291 | *** custom-buffer-sort-alphabetically now defaults to t. | |
292 | ||
293 | *** The color widget now has a "Choose" button, which allows you to | |
294 | choose a color via list-colors-display. | |
295 | ||
f5d6548a JL |
296 | ** Dired-x |
297 | ||
298 | *** dired-jump and dired-jump-other-window called with a prefix argument | |
299 | read a file name from the minibuffer instead of using buffer-file-name. | |
300 | ||
855a2294 DN |
301 | ** VC and related modes |
302 | ||
e97a42c1 | 303 | *** New VC commands: vc-log-incoming, vc-log-outgoing, vc-find-conflicted-file. |
31527c56 | 304 | |
6941ffec DN |
305 | **** vc-log-incoming for Git runs "git fetch" so that the necessary |
306 | data is available locally. | |
307 | ||
eccdfe5f DN |
308 | **** vc-log-incoming and vc-log-outgoing for Git require version 1.7 (or newer). |
309 | ||
54d3626e DN |
310 | *** New key bindings: C-x v I and C-x v O bound to vc-log-incoming and |
311 | vc-log-outgoing, respectively. | |
312 | ||
855a2294 DN |
313 | *** vc-dir for Bzr supports viewing shelve contents and shelving snapshots. |
314 | ||
09158997 | 315 | *** Special markup can be added to log-edit buffers. |
e97a42c1 SM |
316 | The log-edit buffers are expected to have a format similar to email messages |
317 | with headers of the form: | |
318 | Author: <author of this change> | |
319 | Summary: <one line summary of this change> | |
320 | Fixes: <reference to the bug fixed by this change> | |
321 | Some backends handle some of those headers specially, but any unknown header | |
322 | is just left as is in the message, so it is not lost. | |
09158997 | 323 | |
fab43c76 DN |
324 | **** vc-git handles Author: and Date: |
325 | **** vc-hg handles Author: and Date: | |
326 | **** vc-bzr handles Author:, Date: and Fixes: | |
327 | **** vc-mtn handles Author: and Date: | |
328 | ||
b3d42406 DN |
329 | *** Pressing g in a *vc-diff* buffer reruns vc-diff, so it will |
330 | produce an up to date diff. | |
331 | ||
8117868f DN |
332 | ** Directory local variables can apply to file-less buffers. |
333 | For example, adding "(diff-mode . ((mode . whitespace)))" to your | |
d8004abe | 334 | .dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers. |
8117868f | 335 | |
7492acc9 MM |
336 | ** SQL Mode enhancements. |
337 | ||
30c4d8dc MM |
338 | *** Several variables have been marked as safe local variables. The |
339 | variables `sql-product', `sql-user', `sql-server', `sql-database' and | |
340 | `sql-port' can now be safely used as local variables. | |
7492acc9 | 341 | |
9250002f MM |
342 | *** `sql-dialect' is a synonym for `sql-product'. |
343 | ||
74790210 | 344 | *** Added ability to login with a port on MySQL and Postgres. |
7492acc9 | 345 | The custom variable `sql-port' can be specified for connection to |
74790210 MM |
346 | MySQL or Postgres servers. By default, the port is not listed in |
347 | either login parameter, but will be added to the command line if set | |
348 | to a non-zero value. | |
7492acc9 | 349 | |
9250002f MM |
350 | *** Dynamic selection of product in an SQL interactive session. |
351 | If you use `sql-product-interactive' to start an SQL interactive | |
352 | session it uses the current value of `sql-product'. Preceding the | |
353 | invocation with C-u will force it to ask for the product before | |
354 | creating the session. | |
355 | ||
356 | *** Renaming a SQL interactive buffer when it is created. | |
357 | Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres', | |
358 | `sql-mysql', etc.) with C-u will force a new interactive session to be | |
359 | started and will prompt for the new name. This will reduce the need | |
360 | for `sql-rename-buffer' is most common use cases. | |
361 | ||
3bd2cfef MM |
362 | *** Command continuation prompts in SQL interactive mode are suppressed. |
363 | Multiple line commands in SQL interactive mode, generate command | |
364 | continuation prompts which needlessly confuse the output. These | |
365 | prompts are now filtered out from the output. This change impacts | |
366 | multiple line SQL statements entered with C-j between each line, | |
367 | statements yanked into the buffer and statements sent with | |
368 | `sql-send-*' functions. | |
369 | ||
7492acc9 MM |
370 | *** Custom variables control prompting for login parameters. |
371 | Each supported product has a custom variable `sql-*-login-params' | |
372 | which is a list of the parameters to be prompted for before a | |
373 | connection is established. | |
374 | ||
74790210 MM |
375 | The lists consist of the following five tokens: `user', `password', |
376 | `database', `server', and `port'. The order in which they appear is | |
377 | the order in which they are prompted. The tokens symbols can be | |
378 | replaced by a sublist starting with the token and followed by a plist | |
379 | which control the prompting for values. The tokens `user', | |
380 | `database', and `server' each can take a property of :default which | |
381 | specifies the value to be used if no value is entered. The | |
382 | `database', `server', and `port' tokens handle the :completion | |
383 | property which restricts the entry to either one of the values in the | |
384 | list or to one of the values returned by the function provided as the | |
385 | property value. The `database' and `server' tokens also accept the | |
386 | :file property whose value is a regexp to identify useful file names. | |
387 | ||
388 | (user :default DEF) | |
389 | (database :default DEF | |
390 | :file FILEPAT | |
391 | :completion COMPLETE) | |
392 | (server :default DEF | |
393 | :file FILEPAT | |
394 | :completion COMPLETE) | |
395 | ||
396 | The FILEPAT when :file is specified is a regexp that will match valid | |
397 | file names (without the directory portion). Generally these strings | |
398 | will be of the form ".+\.SUF" where SUF is the desired file suffix. | |
399 | ||
400 | When :completion is specified, the COMPLETE corresponds to the | |
401 | PREDICATE argument to the `completing-read' function (a list of | |
402 | possible values or a function returning such a list). | |
5474c40f | 403 | |
30c4d8dc MM |
404 | *** Added `sql-connection-alist' to record login parameter values. |
405 | An alist for recording different username, database and server | |
406 | values. If there are multiple databases that you connect to the | |
407 | parameters needed can be stored in this alist. | |
408 | ||
409 | For example, the following might be set in the user's init.el: | |
410 | ||
411 | (setq sql-connection-alist | |
412 | '((dev (sql-product 'sqlite) | |
413 | (sql-database "/home/mmaug/dev.db")) | |
414 | (prd (sql-product 'oracle) | |
415 | (sql-user "mmaug") | |
416 | (sql-database "iprd2a")))) | |
417 | ||
418 | This defines two connections named "dev" and "prd". | |
419 | ||
420 | *** Added `sql-connect' to use predefined connections. | |
421 | Sets the login parameters based on the values in the | |
422 | `sql-connection-alist' and start a SQL interactive session. Any | |
423 | values specified in the connection will not be prompted for. | |
424 | ||
425 | In the example above, if the user were to invoke M-x sql-connect, they | |
426 | would be prompted for the connection. The user can respond with | |
427 | either "dev" or "prd". The "dev" connection would connect to the | |
428 | SQLite database without prompting; the "prd" connection would prompt | |
429 | for the users password and then connect to the Oracle database. | |
430 | ||
d26b0ea9 | 431 | **** Added SQL->Start... submenu when connections are defined. |
b2957ea8 | 432 | When connections have been defined, there is a submenu available that |
d26b0ea9 MM |
433 | allows the user to select one to start a SQLi session. The "Start |
434 | SQLi Session" item moves to the "Start..." submenu when cnnections | |
435 | have been defined. | |
436 | ||
437 | **** Added "Save Connection" menu item in SQLi buffers. | |
438 | When a SQLi session is not started by a connection then | |
439 | `sql-save-connection' will gather the login params specified for the | |
440 | session and save them as a new connection. | |
441 | ||
74790210 MM |
442 | *** List database objects and details. |
443 | Once a SQL interactive session has been started, you can get a list of | |
444 | the objects in the database and see details of those objects. The | |
445 | objects shown and the details available are product specific. | |
446 | ||
447 | **** List all objects. | |
448 | Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all | |
449 | objects" will list all the objects in the database. At a minimum it | |
450 | lists the tables and views in the database. Preceeding the command by | |
451 | universal argument may provide additional details or extend the | |
452 | listing to include other schemas objects. The list will appear in a | |
453 | separate window in view-mode. | |
454 | ||
455 | **** List Table details. | |
456 | Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table | |
457 | details" will ask for the name of a database table or view and display | |
458 | the list of columns in the relation. Preceeding the comand with the | |
459 | universal argument may provide additional details about each column. | |
460 | The list will appear in a separate window in view-mode. | |
461 | ||
7492acc9 MM |
462 | *** Added option `sql-send-terminator'. |
463 | When set makes sure that each command sent with `sql-send-*' commands | |
464 | are properly terminated and submitted to the SQL processor. | |
465 | ||
466 | *** Added option `sql-oracle-scan-on'. | |
467 | When set commands sent to Oracle's SQL*Plus are scanned for strings | |
30c4d8dc MM |
468 | starting with an ampersand and the user is asked for replacement text. |
469 | In general, the SQL*Plus option SCAN should always be set OFF under | |
470 | SQL interactive mode and this option used in its place. | |
7492acc9 MM |
471 | |
472 | *** SQL interactive mode will replace tabs with spaces. | |
473 | This prevents the comand interpretter for MySQL and Postgres from | |
474 | listing object name completions when being sent text via | |
475 | `sql-send-*' functions. | |
476 | ||
477 | *** An API for manipulating SQL product definitions has been added. | |
478 | ||
5e418f17 JL |
479 | ** s-region.el is now declared obsolete, superceded by shift-select-mode |
480 | enabled by default in 23.1. | |
481 | ||
691cf4a0 NR |
482 | ** gdb-mi |
483 | ||
484 | *** GDB User Interface migrated to GDB Machine Interface and now | |
485 | supports multithread non-stop debugging and debugging of several | |
486 | threads simultaneously. | |
487 | ||
37221432 MA |
488 | ** D-Bus |
489 | ||
490 | *** It is possible now, to access alternative buses than the default | |
491 | system or session bus. | |
492 | ||
459bba37 MA |
493 | ** Tramp |
494 | ||
495 | *** The following access methods are discontinued: "ssh1_old", | |
496 | "ssh2_old", "scp1_old", "scp2_old" and "fish". | |

499 | * New Modes and Packages in Emacs 24.1 | |
d445b3f8 | 500 | |
3b843809 SM |
501 | ** New global minor modes electric-pair-mode and electric-indent-mode. |
502 | ||
d02c9bcd SM |
503 | ** pcase.el provides the ML-style pattern matching macro `pcase'. |
504 | ||
5ad4bef5 SM |
505 | ** smie.el is a package providing a simple generic indentation engine. |
506 | ||
7725ebb7 MA |
507 | ** secrets.el is an implementation of the Secret Service API, an |
508 | interface to password managers like GNOME Keyring or KDE Wallet. The | |
065f2743 MA |
509 | Secret Service API requires D-Bus for communication. The command |
510 | `secrets-show-secrets' offers a buffer with a visualization of the | |
511 | secrets. | |
7725ebb7 | 512 | |
f9e78150 MA |
513 | ** notifications.el provides an implementation of the Desktop |
514 | Notifications API. It requires D-Bus for communication. | |

517 | * Incompatible Lisp Changes in Emacs 24.1 | |
6dfcbe31 | 518 | |
288cf4e9 SM |
519 | ** A backquote not followed by a space is now always treated as new-style. |
520 | ||
fd5c9dfa | 521 | ** Test for special mode-class was moved from view-file to view-buffer. |
288cf4e9 SM |
522 | FIXME: This only says what was changed, but not what are the |
523 | programmer-visible consequences. | |
fd5c9dfa | 524 | |
3b7e1d5f SM |
525 | ** Passing a nil argument to a minor mode function now turns the mode |
526 | ON unconditionally. | |
6431f2e6 CY |
527 | |
528 | ** During startup, Emacs no longer adds entries for `menu-bar-lines' | |
529 | and `tool-bar-lines' to `default-frame-alist' and | |
530 | `initial-frame-alist'. With these alist entries omitted, `make-frame' | |
531 | checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to | |
532 | determine whether to create a menu-bar or tool-bar, respectively. | |
533 | If the alist entries are added, they override the value of | |
534 | `menu-bar-mode'/`tool-bar-mode'. | |
535 | ||
fe0aa820 CY |
536 | ** Regions created by mouse dragging are now normal active regions, |
537 | similar to the ones created by shift-selection. In previous Emacs | |
538 | versions, these regions were delineated by `mouse-drag-overlay', which | |
539 | has now been removed. | |

542 | * Lisp changes in Emacs 24.1 | |
9097e8af | 543 | |
cf38dd42 SM |
544 | ** New variable syntax-propertize-function to set syntax-table properties. |
545 | Replaces font-lock-syntactic-keywords which are now obsolete. | |
546 | This allows syntax-table properties to be set independently from font-lock: | |
547 | just call syntax-propertize to make sure the text is propertized. | |
548 | Together with this new variable come a new hook | |
549 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
550 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
551 | as-is; and syntax-propertize-rules which provides a new way to specify | |
552 | syntactic rules. | |
553 | ||
a2e5caf7 SM |
554 | ** New hook post-self-insert-hook run at the end of self-insert-command. |
555 | ||
7cf78aac | 556 | +++ |
c5683ceb | 557 | ** Syntax tables support a new "comment style c" additionally to style b. |
4e2db1fe | 558 | ** frame-local variables cannot be let-bound any more. |
10dcc561 | 559 | ** prog-mode is a new major-mode meant to be the parent of programming mode. |
f44379e7 SM |
560 | ** define-minor-mode accepts a new keyword :variable. |
561 | ||
b2957ea8 | 562 | ** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
563 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
564 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
565 | argument is supplied (see Trash changes, above). | |
53967e09 | 566 | |
8f92b8ad SM |
567 | ** buffer-substring-filters is obsoleted by filter-buffer-substring-functions. |
568 | ||
00278747 SM |
569 | ** New completion style `substring'. |
570 | ||
00fe2df1 JL |
571 | ** Image API |
572 | ||
573 | *** When the image type is one of listed in `image-animated-types' | |
1546c559 | 574 | and the number of sub-images in the image is more than one, then the |
00fe2df1 JL |
575 | new function `create-animated-image' creates an animated image where |
576 | sub-images are displayed successively with the duration defined by | |
577 | `image-animate-max-time' and the delay between sub-images defined | |
578 | by the Graphic Control Extension of the image. | |
579 | ||
1546c559 JL |
580 | *** `image-extension-data' is renamed to `image-metadata'. |
581 | ||
71c17aec LMI |
582 | ** XML and HTML parsing |
583 | ||
584 | *** If Emacs is compiled with libxml2 support (which is the default), | |
4b9832a6 CY |
585 | two new Emacs Lisp-level functions are defined: |
586 | `xml-parse-html-string-internal' (which will parse "real world" HTML) | |
587 | and `xml-parse-string-internal' (which parses XML). Both return an | |
588 | Emacs Lisp parse tree. | |
589 | ||
590 | FIXME: These should be front-ended by xml.el. | |
591 | ||
cf16af42 | 592 | ** FIXME GnuTLS |
71c17aec | 593 | |
a6020335 MH |
594 | ** Isearch |
595 | ||
596 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | |
597 | ||
9326ba26 CY |
598 | ** Progress reporters can now "spin". |
599 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
600 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
601 | time you call `progress-reporter-update' on that progress reporter, | |
602 | with a nil or omitted VALUE argument, the reporter message is | |
603 | displayed with a "spinning bar". | |
