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 | ||
e547b051 | 40 | --- |
30c4d8dc | 41 | ** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
e547b051 J |
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 | |
44 | --without-gconf. | |
45 | ||
d9170db5 DN |
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. | |
b2957ea8 | 48 | This is not a new feature; only the configure flag is new. |

58 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte |
59 | command line arguments no longer have any effect. (They were declared | |
60 | obsolete in Emacs 23.) | |

eb199145 | 63 | * Changes in Emacs 24.1 |
7841339b | 64 | |
2a847524 CY |
65 | ** emacsclient changes |
66 | ||
67 | *** New emacsclient argument --parent-id ID can be used to open a | |
0191e222 CY |
68 | client frame in parent X window ID, via XEmbed. This works like the |
69 | --parent-id argument to Emacs. | |
70 | ||
2a847524 CY |
71 | *** If emacsclient shuts down as a result of Emacs signalling an |
72 | error, its exit status is 1. | |
73 | ||
902a6d8d SM |
74 | ** Completion can cycle, depending on completion-cycle-threshold. |
75 | ||
2372f278 SM |
76 | ** auto-mode-case-fold is now enabled by default. |
77 | ||
f4b6ba46 EZ |
78 | +++ |
79 | ** Emacs now supports display and editing of bidirectional text. | |
f4b6ba46 EZ |
80 | |
81 | See the node "Bidirectional Editing" in the Emacs Manual for some | |
82 | initial documentation. | |
83 | ||
84 | To turn this on in any given buffer, set the buffer-local variable | |
85 | `bidi-display-reordering' to a non-nil value. The default is nil. | |
86 | ||
87 | The buffer-local variable `bidi-paragraph-direction', if non-nil, | |
88 | forces each paragraph in the buffer to have its base direction | |
89 | according to the value of this variable. Possible values are | |
90 | `right-to-left' and `left-to-right'. If the value is nil (the | |
91 | default), Emacs determines the base direction of each paragraph from | |
92 | its text, as specified by the Unicode Bidirectional Algorithm. | |
93 | ||
d20e1419 EZ |
94 | The function `current-bidi-paragraph-direction' returns the actual |
95 | value of paragraph base direction at point. | |
96 | ||
f4b6ba46 EZ |
97 | Reordering of bidirectional text for display in Emacs is a "Full |
98 | bidirectionality" class implementation of the Unicode Bidirectional | |
99 | Algorithm. | |
100 | ||
46759717 EZ |
101 | Note that some advanced display features, such as overlay strings and |
102 | `display' text properties, do not yet work correctly when | |
103 | bidirectional text is reordered for display. | |
104 | ||
303500aa | 105 | ** GTK scroll-bars are now placed on the right by default. |
52834b6b CY |
106 | Use `set-scroll-bar-mode' to change this. |
107 | ||
20fe03ad | 108 | ** GTK tool bars can have just text, just images or images and text. |
d8004abe | 109 | Customize `tool-bar-style' to choose style. On a Gnome desktop, the default |
20fe03ad JD |
110 | is taken from the desktop settings. |
111 | ||
8b2dd508 JD |
112 | ** GTK tool bars can be placed on the left/right or top/bottom of the frame. |
113 | The frame-parameter tool-bar-position controls this. It takes the values | |
1c0d77cc | 114 | top, left, right or bottom. The Options => Show/Hide menu has entries |
8b2dd508 JD |
115 | for this. |
116 | ||
8740c12d | 117 | ** ImageMagick support. |
b2fa3a09 GM |
118 | It is now possible to use the ImageMagick library to load many new |
119 | image formats in Emacs. By default, Emacs links with the ImageMagick | |
120 | libraries if they are present at build time. To disable this, use | |
8ea189f7 | 121 | the configure option `--without-imagemagick'. |
16a91140 | 122 | |
8740c12d GM |
123 | The new function `imagemagick-types' returns a list of image file |
124 | extensions that your installation of ImageMagick supports. The | |
125 | function `imagemagick-register-types' enables ImageMagick support for | |
b2957ea8 | 126 | these image types, minus those listed in `imagemagick-types-inhibit'. |
16a91140 | 127 | |
8740c12d | 128 | See the Emacs Lisp Reference Manual for more information. |
16a91140 | 129 | |
3a46642b J |
130 | ** The colors for selected text (the region face) are taken from the GTK |
131 | theme when Emacs is built with GTK. | |
132 | ||
aa1859f5 J |
133 | ** Emacs uses GTK tooltips by default if built with GTK. You can turn that |
134 | off by customizing x-gtk-use-system-tooltips. | |
135 | ||
1ecb2d3f | 136 | ** Lucid menus and dialogs can display antialiased fonts if Emacs is built |
a6ac7fc4 JD |
137 | with Xft. To change font, use X resource faceName, for example: |
138 | Emacs.pane.menubar.faceName: Courier-12 | |
139 | Set faceName to none and use font to use the old X fonts. | |
99852628 | 140 | |
917794d5 CY |
141 | ** On graphical displays, the mode-line no longer ends in dashes. |
142 | ||
b7d65a5f GM |
143 | ** Basic SELinux support has been added. |
144 | This requires Emacs to be linked with libselinux at build time. | |
145 | ||
d8004abe GM |
146 | *** Emacs preserves the SELinux file context when backing up, and |
147 | optionally when copying files. To this end, copy-file has an extra | |
148 | optional argument, and backup-buffer and friends include the SELinux | |
149 | context in their return values. | |
b7d65a5f GM |
150 | |
151 | *** The new functions file-selinux-context and set-file-selinux-context | |
152 | get and set the SELinux context of a file. | |
153 | ||
a5bee597 MA |
154 | *** Tramp offers handlers for file-selinux-context and set-file-selinux-context |
155 | for remote machines which support SELinux. | |
156 | ||
9c524fcb | 157 | ** The function kill-emacs is now run upon receipt of the signals SIGTERM |
383ebd15 | 158 | and SIGHUP, and upon SIGINT in batch mode. |
9c524fcb GM |
159 | |
160 | ** kill-emacs-hook is now also run in batch mode. | |
161 | ||
79ce172a | 162 | ** New scrolling commands `scroll-up-command' and `scroll-down-command' |
7b05466f JL |
163 | (bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom |
164 | of buffer at first key-press (instead moves to top/bottom of buffer) | |
165 | when a new variable `scroll-error-top-bottom' is non-nil. | |
79ce172a | 166 | |
5a97d2da JL |
167 | ** New scrolling commands `scroll-up-line' and `scroll-down-line' |
168 | scroll a line instead of full screen. | |
169 | ||
a4b000fb | 170 | ** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 171 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
9013a7f8 | 172 | |
f1a5d776 CY |
173 | ** Trash changes |
174 | ||
175 | *** `delete-by-moving-to-trash' now only affects commands that specify | |
176 | trashing. This avoids inadvertently trashing temporary files. | |
177 | ||
178 | *** Calling `delete-file' or `delete-directory' with a prefix argument | |
179 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
180 | ||
f0bf7c8e JL |
181 | ** New option `list-colors-sort' defines the color sort order |
182 | for `list-colors-display'. | |
183 | ||
44198b6e CY |
184 | ** An Emacs Lisp package manager is now included. |
185 | This is a convenient way to download and install additional packages, | |
42d9cffa | 186 | from a package repository at elpa.gnu.org. |
cb6c4991 CY |
187 | |
188 | *** `M-x list-packages' shows a list of packages, which can be | |
189 | selected for installation. | |
190 | ||
191 | *** New command `describe-package', bound to `C-h P'. | |
44198b6e CY |
192 | |
193 | *** By default, all installed packages are loaded and activated | |
194 | automatically when Emacs starts up. To disable this, set | |
195 | `package-enable-at-startup' to nil. To change which packages are | |
196 | loaded, customize `package-load-list'. | |
197 | ||
f065864f CY |
198 | ** Custom Themes |
199 | ||
200 | *** `M-x customize-themes' lists Custom themes which can be enabled. | |
201 | ||
782b5e8d CY |
202 | *** New option `custom-theme-load-path' is the load path for themes. |
203 | Emacs no longer looks for custom themes in `load-path'. The default | |
204 | is to search in `custom-theme-directory', followed by a built-in theme | |
205 | directory named "themes/" in `data-directory'. | |
206 | ||
4ddf410a MA |
207 | ** The user option `remote-file-name-inhibit-cache' controls whether |
208 | the remote file-name cache is used for read access. | |
209 | ||
17284e30 GM |
210 | ** The standalone programs lib-src/digest-doc and sorted-doc have been |
211 | replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'. | |
212 | ||
0bfd685e | 213 | \f |
eb199145 | 214 | * Editing Changes in Emacs 24.1 |
b350bdf2 | 215 | |
a982c7ec CY |
216 | ** completion-at-point is now an alias for complete-symbol. |
217 | ||
b9229673 CY |
218 | ** Deletion changes |
219 | ||
220 | *** New option `delete-active-region'. | |
221 | If non-nil, C-d, [delete], and DEL delete the region if it is active | |
222 | and no prefix argument is given. If set to `kill', these commands | |
223 | kill instead. | |
224 | ||
225 | *** New command `delete-forward-char', bound to C-d and [delete]. | |
42d9cffa CY |
226 | This is meant for interactive use, and obeys `delete-active-region'. |
227 | The command `delete-char' does not obey `delete-active-region'. | |
b9229673 CY |
228 | |
229 | *** `delete-backward-char' is now a Lisp function. | |
230 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
231 | However, the byte compiler now warns if it is called from Lisp; you | |
232 | should use delete-char with a negative argument instead. | |
233 | ||
234 | *** The option `mouse-region-delete-keys' has been deleted. | |
235 | ||
f9d71b42 CY |
236 | ** Selection changes. |
237 | ||
7c23dd44 | 238 | The default handling of clipboard and primary selections has been |
42d9cffa CY |
239 | changed to conform with other X applications. The exact changes are |
240 | described below; in short, mouse commands to select and paste text now | |
241 | use the primary selection, while all other commands for killing and | |
242 | yanking text now use the clipboard. | |
7c23dd44 | 243 | |
42d9cffa CY |
244 | *** Merely selecting text (e.g. with drag-mouse-1) does not add it to |
245 | the kill-ring. On systems with a primary selection separate from the | |
246 | clipboard (such as X), the selected text is put in the primary | |
247 | selection. | |
248 | ||
249 | *** mouse-2 is now bound to `mouse-yank-primary', which pastes from | |
250 | the primary selection regardless of the contents of the kill-ring. | |
251 | ||
252 | *** Commands that kill text or copy it to the kill-ring (M-w, C-w, | |
253 | C-k, etc.) also put the killed text into the clipboard. This change | |
254 | also means that the "Copy", "Cut", and "Paste" items in the "Edit" | |
255 | menu are now exactly equivalent to, respectively M-w, C-w, and C-y. | |
256 | ||
257 | *** Yank commands, such as C-y and M-y, retrieve text from the | |
258 | clipboard if it is available. | |
259 | ||
260 | *** The above changes are reflected in the following new defaults: | |
261 | ||
262 | **** `select-active-regions' now defaults to t. | |
d1b08c88 | 263 | It also accepts a new value, `only', which means to only set the |
7c23dd44 CY |
264 | primary selection for temporarily active regions (usually made by |
265 | mouse-dragging or shift-selection). | |
266 | ||
42d9cffa | 267 | **** `mouse-2' is now bound to `mouse-yank-primary'. |
7c9b11be | 268 | Previously, it was bound to `mouse-yank-at-click' (which is now |
4c0f50c9 | 269 | unbound by default). |
f9d71b42 | 270 | |
42d9cffa CY |
271 | **** `x-select-enable-clipboard' now defaults to t on all platforms. |
272 | Note that this variable was already non-nil by default on MS-Windows, | |
273 | which does not support the primary selection between applications. | |
f9d71b42 | 274 | |
42d9cffa | 275 | **** `x-select-enable-primary' now defaults to nil. |
7c9b11be EZ |
276 | This variable exists only on X; its default value was t in previous |
277 | versions. | |
2490cbbc | 278 | |
42d9cffa CY |
279 | **** `mouse-drag-copy-region' now defaults to nil. |
280 | ||
281 | *** To return to the previous behavior, where mouse commands use the | |
282 | clipboard, change `mouse-drag-copy-region' and (on X only) | |
283 | `x-select-enable-primary' to t. If you don't want Emacs to put the | |
284 | text into the clipboard, only to the primary selection, additionally | |
285 | set `x-select-enable-clipboard' to nil. | |
f9d71b42 | 286 | |
084e6df3 JD |
287 | *** Support for X cut buffers has been removed. |
288 | ||

eb199145 | 290 | * Changes in Specialized Modes and Packages in Emacs 24.1 |
efeb796b | 291 | |
b879a6e2 SM |
292 | ** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. |
293 | ||
360ac530 | 294 | ** FIXME: xdg-open for browse-url and reportbug, 2010/08. |
0ac3effe | 295 | |
b3671a51 JL |
296 | ** Archive Mode has basic support to browse 7z archives. |
297 | ||
8a8d54cd VD |
298 | ** ERC changes |
299 | ||
300 | *** New vars `erc-autojoin-timing' and `erc-autojoin-delay'. | |
301 | If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a | |
302 | successful NickServ identification, or after `erc-autojoin-delay' | |
303 | seconds. The default value, 'ident, means to autojoin immediately | |
304 | after connecting. | |
305 | ||
5c0c0f77 LMI |
306 | *** New variable `erc-coding-system-precedence': If we use `undecided' |
307 | as the server coding system, this variable will then be consulted. | |
308 | The default is to decode strings that can be decoded as utf-8 as | |
309 | utf-8, and do the normal `undecided' decoding for the rest. | |
310 | ||
27d3cd56 CY |
311 | ** In ido-mode, C-v is no longer bound to ido-toggle-vc. |
312 | The reason is that this interferes with cua-mode. | |
313 | ||
c1e25821 | 314 | ** partial-completion-mode is now obsolete. |
79ccd68f SM |
315 | You can get a comparable behavior with: |
316 | (setq completion-styles '(partial-completion initials)) | |
317 | (setq completion-pcm-complete-word-inserts-delimiters t) | |
c1e25821 | 318 | |
18c812bd | 319 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
b2957ea8 | 320 | |
1d83b0e9 GM |
321 | ** server can listen on a specific port using the server-port option. |
322 | ||
cf16af42 GM |
323 | ** Calendar, Diary, and Appt |
324 | ||
325 | --- | |
326 | *** The obsolete (since Emacs 22.1) method of enabling the appt package | |
327 | by adding appt-make-list to diary-hook has been removed. Use appt-activate. | |
328 | ||
329 | --- | |
330 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: | |
331 | appt-issue-message (use the function appt-activate) | |
332 | appt-visible/appt-msg-window (use the variable appt-display-format) | |
333 | ||
334 | --- | |
335 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: | |
336 | view-diary-entries, list-diary-entries, show-all-diary-entries | |
337 | ||
52834b6b CY |
338 | ** Customize |
339 | ||
340 | *** Customize buffers now contain a search field. | |
341 | The search is performed using `customize-apropos'. | |
42d9cffa | 342 | To turn off the search field, set custom-search-field to nil. |
52834b6b CY |
343 | |
344 | *** Custom options now start out hidden if at their default values. | |
345 | Use the arrow to the left of the option name to toggle visibility. | |
346 | ||
347 | *** custom-buffer-sort-alphabetically now defaults to t. | |
348 | ||
349 | *** The color widget now has a "Choose" button, which allows you to | |
350 | choose a color via list-colors-display. | |
351 | ||
f5d6548a JL |
352 | ** Dired-x |
353 | ||
354 | *** dired-jump and dired-jump-other-window called with a prefix argument | |
355 | read a file name from the minibuffer instead of using buffer-file-name. | |
356 | ||
8117868f DN |
357 | ** Directory local variables can apply to file-less buffers. |
358 | For example, adding "(diff-mode . ((mode . whitespace)))" to your | |
d8004abe | 359 | .dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers. |
8117868f | 360 | |
7492acc9 MM |
361 | ** SQL Mode enhancements. |
362 | ||
30c4d8dc MM |
363 | *** Several variables have been marked as safe local variables. The |
364 | variables `sql-product', `sql-user', `sql-server', `sql-database' and | |
365 | `sql-port' can now be safely used as local variables. | |
7492acc9 | 366 | |
9250002f MM |
367 | *** `sql-dialect' is a synonym for `sql-product'. |
368 | ||
74790210 | 369 | *** Added ability to login with a port on MySQL and Postgres. |
7492acc9 | 370 | The custom variable `sql-port' can be specified for connection to |
74790210 MM |
371 | MySQL or Postgres servers. By default, the port is not listed in |
372 | either login parameter, but will be added to the command line if set | |
373 | to a non-zero value. | |
7492acc9 | 374 | |
9250002f MM |
375 | *** Dynamic selection of product in an SQL interactive session. |
376 | If you use `sql-product-interactive' to start an SQL interactive | |
377 | session it uses the current value of `sql-product'. Preceding the | |
378 | invocation with C-u will force it to ask for the product before | |
379 | creating the session. | |
380 | ||
381 | *** Renaming a SQL interactive buffer when it is created. | |
382 | Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres', | |
383 | `sql-mysql', etc.) with C-u will force a new interactive session to be | |
384 | started and will prompt for the new name. This will reduce the need | |
385 | for `sql-rename-buffer' is most common use cases. | |
386 | ||
3bd2cfef MM |
387 | *** Command continuation prompts in SQL interactive mode are suppressed. |
388 | Multiple line commands in SQL interactive mode, generate command | |
389 | continuation prompts which needlessly confuse the output. These | |
390 | prompts are now filtered out from the output. This change impacts | |
391 | multiple line SQL statements entered with C-j between each line, | |
392 | statements yanked into the buffer and statements sent with | |
393 | `sql-send-*' functions. | |
394 | ||
7492acc9 MM |
395 | *** Custom variables control prompting for login parameters. |
396 | Each supported product has a custom variable `sql-*-login-params' | |
397 | which is a list of the parameters to be prompted for before a | |
398 | connection is established. | |
399 | ||
74790210 MM |
400 | The lists consist of the following five tokens: `user', `password', |
401 | `database', `server', and `port'. The order in which they appear is | |
402 | the order in which they are prompted. The tokens symbols can be | |
403 | replaced by a sublist starting with the token and followed by a plist | |
404 | which control the prompting for values. The tokens `user', | |
405 | `database', and `server' each can take a property of :default which | |
406 | specifies the value to be used if no value is entered. The | |
407 | `database', `server', and `port' tokens handle the :completion | |
408 | property which restricts the entry to either one of the values in the | |
409 | list or to one of the values returned by the function provided as the | |
410 | property value. The `database' and `server' tokens also accept the | |
411 | :file property whose value is a regexp to identify useful file names. | |
412 | ||
413 | (user :default DEF) | |
414 | (database :default DEF | |
415 | :file FILEPAT | |
416 | :completion COMPLETE) | |
417 | (server :default DEF | |
418 | :file FILEPAT | |
419 | :completion COMPLETE) | |
420 | ||
421 | The FILEPAT when :file is specified is a regexp that will match valid | |
422 | file names (without the directory portion). Generally these strings | |
423 | will be of the form ".+\.SUF" where SUF is the desired file suffix. | |
424 | ||
425 | When :completion is specified, the COMPLETE corresponds to the | |
426 | PREDICATE argument to the `completing-read' function (a list of | |
427 | possible values or a function returning such a list). | |
5474c40f | 428 | |
30c4d8dc MM |
429 | *** Added `sql-connection-alist' to record login parameter values. |
430 | An alist for recording different username, database and server | |
431 | values. If there are multiple databases that you connect to the | |
432 | parameters needed can be stored in this alist. | |
433 | ||
434 | For example, the following might be set in the user's init.el: | |
435 | ||
436 | (setq sql-connection-alist | |
437 | '((dev (sql-product 'sqlite) | |
438 | (sql-database "/home/mmaug/dev.db")) | |
439 | (prd (sql-product 'oracle) | |
440 | (sql-user "mmaug") | |
441 | (sql-database "iprd2a")))) | |
442 | ||
443 | This defines two connections named "dev" and "prd". | |
444 | ||
445 | *** Added `sql-connect' to use predefined connections. | |
446 | Sets the login parameters based on the values in the | |
447 | `sql-connection-alist' and start a SQL interactive session. Any | |
448 | values specified in the connection will not be prompted for. | |
449 | ||
450 | In the example above, if the user were to invoke M-x sql-connect, they | |
451 | would be prompted for the connection. The user can respond with | |
452 | either "dev" or "prd". The "dev" connection would connect to the | |
453 | SQLite database without prompting; the "prd" connection would prompt | |
454 | for the users password and then connect to the Oracle database. | |
455 | ||
d26b0ea9 | 456 | **** Added SQL->Start... submenu when connections are defined. |
b2957ea8 | 457 | When connections have been defined, there is a submenu available that |
d26b0ea9 MM |
458 | allows the user to select one to start a SQLi session. The "Start |
459 | SQLi Session" item moves to the "Start..." submenu when cnnections | |
460 | have been defined. | |
461 | ||
462 | **** Added "Save Connection" menu item in SQLi buffers. | |
463 | When a SQLi session is not started by a connection then | |
464 | `sql-save-connection' will gather the login params specified for the | |
465 | session and save them as a new connection. | |
466 | ||
74790210 MM |
467 | *** List database objects and details. |
468 | Once a SQL interactive session has been started, you can get a list of | |
469 | the objects in the database and see details of those objects. The | |
470 | objects shown and the details available are product specific. | |
471 | ||
472 | **** List all objects. | |
473 | Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all | |
474 | objects" will list all the objects in the database. At a minimum it | |
475 | lists the tables and views in the database. Preceeding the command by | |
476 | universal argument may provide additional details or extend the | |
477 | listing to include other schemas objects. The list will appear in a | |
478 | separate window in view-mode. | |
479 | ||
480 | **** List Table details. | |
481 | Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table | |
482 | details" will ask for the name of a database table or view and display | |
483 | the list of columns in the relation. Preceeding the comand with the | |
484 | universal argument may provide additional details about each column. | |
485 | The list will appear in a separate window in view-mode. | |
486 | ||
7492acc9 MM |
487 | *** Added option `sql-send-terminator'. |
488 | When set makes sure that each command sent with `sql-send-*' commands | |
489 | are properly terminated and submitted to the SQL processor. | |
490 | ||
491 | *** Added option `sql-oracle-scan-on'. | |
492 | When set commands sent to Oracle's SQL*Plus are scanned for strings | |
30c4d8dc MM |
493 | starting with an ampersand and the user is asked for replacement text. |
494 | In general, the SQL*Plus option SCAN should always be set OFF under | |
495 | SQL interactive mode and this option used in its place. | |
7492acc9 MM |
496 | |
497 | *** SQL interactive mode will replace tabs with spaces. | |
498 | This prevents the comand interpretter for MySQL and Postgres from | |
499 | listing object name completions when being sent text via | |
500 | `sql-send-*' functions. | |
501 | ||
502 | *** An API for manipulating SQL product definitions has been added. | |
503 | ||
5e418f17 JL |
504 | ** s-region.el is now declared obsolete, superceded by shift-select-mode |
505 | enabled by default in 23.1. | |
506 | ||
691cf4a0 NR |
507 | ** gdb-mi |
508 | ||
509 | *** GDB User Interface migrated to GDB Machine Interface and now | |
510 | supports multithread non-stop debugging and debugging of several | |
511 | threads simultaneously. | |
512 | ||
37221432 MA |
513 | ** D-Bus |
514 | ||
515 | *** It is possible now, to access alternative buses than the default | |
516 | system or session bus. | |
517 | ||
459bba37 MA |
518 | ** Tramp |
519 | ||
520 | *** The following access methods are discontinued: "ssh1_old", | |
521 | "ssh2_old", "scp1_old", "scp2_old" and "fish". | |

526 | ** New global minor modes electric-pair-mode and electric-indent-mode. |
527 | ||
d02c9bcd SM |
528 | ** pcase.el provides the ML-style pattern matching macro `pcase'. |
529 | ||
5ad4bef5 SM |
530 | ** smie.el is a package providing a simple generic indentation engine. |
531 | ||
7725ebb7 MA |
532 | ** secrets.el is an implementation of the Secret Service API, an |
533 | interface to password managers like GNOME Keyring or KDE Wallet. The | |
065f2743 MA |
534 | Secret Service API requires D-Bus for communication. The command |
535 | `secrets-show-secrets' offers a buffer with a visualization of the | |
536 | secrets. | |
7725ebb7 | 537 | |
f9e78150 MA |
538 | ** notifications.el provides an implementation of the Desktop |

542 | * Incompatible Lisp Changes in Emacs 24.1 | |
6dfcbe31 | 543 | |
c4d17d50 SM |
544 | ** Remove obsolete name `e' (use `float-e' instead). |
545 | ||
288cf4e9 SM |
546 | ** A backquote not followed by a space is now always treated as new-style. |
547 | ||
fd5c9dfa | 548 | ** Test for special mode-class was moved from view-file to view-buffer. |
288cf4e9 SM |
549 | FIXME: This only says what was changed, but not what are the |
550 | programmer-visible consequences. | |
fd5c9dfa | 551 | |
3b7e1d5f SM |
552 | ** Passing a nil argument to a minor mode function now turns the mode |
553 | ON unconditionally. | |
6431f2e6 CY |
554 | |
555 | ** During startup, Emacs no longer adds entries for `menu-bar-lines' | |
556 | and `tool-bar-lines' to `default-frame-alist' and | |
557 | `initial-frame-alist'. With these alist entries omitted, `make-frame' | |
558 | checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to | |
559 | determine whether to create a menu-bar or tool-bar, respectively. | |
560 | If the alist entries are added, they override the value of | |
561 | `menu-bar-mode'/`tool-bar-mode'. | |
562 | ||
fe0aa820 CY |
563 | ** Regions created by mouse dragging are now normal active regions, |
564 | similar to the ones created by shift-selection. In previous Emacs | |
565 | versions, these regions were delineated by `mouse-drag-overlay', which | |
566 | has now been removed. | |
d6d8ee7a | 567 | |
4583e796 GM |
568 | ** cl.el no longer provides `cl-19'. |
569 | ||

592 | * Lisp changes in Emacs 24.1 | |
9097e8af | 593 | |
2e288d54 JB |
594 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
595 | The variable is now used to load all kind of supported dynamic libraries, | |
596 | not just image libraries. The previous name is still available as an | |
597 | obsolete alias. | |
598 | ||
cf38dd42 SM |
599 | ** New variable syntax-propertize-function to set syntax-table properties. |
600 | Replaces font-lock-syntactic-keywords which are now obsolete. | |
601 | This allows syntax-table properties to be set independently from font-lock: | |
602 | just call syntax-propertize to make sure the text is propertized. | |
603 | Together with this new variable come a new hook | |
604 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
605 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
606 | as-is; and syntax-propertize-rules which provides a new way to specify | |
607 | syntactic rules. | |
608 | ||
a2e5caf7 SM |
609 | ** New hook post-self-insert-hook run at the end of self-insert-command. |
610 | ||
7cf78aac | 611 | +++ |
c5683ceb | 612 | ** Syntax tables support a new "comment style c" additionally to style b. |
4e2db1fe | 613 | ** frame-local variables cannot be let-bound any more. |
10dcc561 | 614 | ** prog-mode is a new major-mode meant to be the parent of programming mode. |
f44379e7 SM |
615 | ** define-minor-mode accepts a new keyword :variable. |
616 | ||
b2957ea8 | 617 | ** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
618 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
619 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
620 | argument is supplied (see Trash changes, above). | |
53967e09 | 621 | |
8f92b8ad SM |
622 | ** buffer-substring-filters is obsoleted by filter-buffer-substring-functions. |
623 | ||
00278747 SM |
624 | ** New completion style `substring'. |
625 | ||
9317e499 CY |
626 | ** `facemenu-read-color' is now an alias for `read-color'. |
627 | The command `read-color' now requires a match for a color name or RGB | |
628 | triplet, instead of signalling an error if the user provides a invalid | |
629 | input. | |
630 | ||
631 | ||
00fe2df1 JL |
632 | ** Image API |
633 | ||
634 | *** When the image type is one of listed in `image-animated-types' | |
1546c559 | 635 | and the number of sub-images in the image is more than one, then the |
00fe2df1 JL |
636 | new function `create-animated-image' creates an animated image where |
637 | sub-images are displayed successively with the duration defined by | |
638 | `image-animate-max-time' and the delay between sub-images defined | |
639 | by the Graphic Control Extension of the image. | |
640 | ||
1546c559 JL |
641 | *** `image-extension-data' is renamed to `image-metadata'. |
642 | ||
71c17aec LMI |
643 | ** XML and HTML parsing |
644 | ||
645 | *** If Emacs is compiled with libxml2 support (which is the default), | |
4b9832a6 CY |
646 | two new Emacs Lisp-level functions are defined: |
647 | `xml-parse-html-string-internal' (which will parse "real world" HTML) | |
648 | and `xml-parse-string-internal' (which parses XML). Both return an | |
649 | Emacs Lisp parse tree. | |
650 | ||
651 | FIXME: These should be front-ended by xml.el. | |
652 | ||
cf16af42 | 653 | ** FIXME GnuTLS |
71c17aec | 654 | |
a6020335 MH |
655 | ** Isearch |
656 | ||
657 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | |
658 | ||
9326ba26 CY |
659 | ** Progress reporters can now "spin". |
660 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
661 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
662 | time you call `progress-reporter-update' on that progress reporter, | |
663 | with a nil or omitted VALUE argument, the reporter message is | |
664 | displayed with a "spinning bar". | |
