27 | ** Configure links against libselinux if it is found. |
28 | You can disable this by using --without-selinux. | |
29 | ||

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. | |

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 | ||

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. |

69 | ||
70 | *** New emacsclient argument --parent-id ID can be used to open a | |
0191e222 CY |
71 | client frame in parent X window ID, via XEmbed. This works like the |
72 | --parent-id argument to Emacs. | |

74 | *** If emacsclient shuts down as a result of Emacs signalling an |
75 | error, its exit status is 1. | |

81 | +++ |
82 | ** Emacs now supports display and editing of bidirectional text. | |
f4b6ba46 EZ |
83 | |
84 | See the node "Bidirectional Editing" in the Emacs Manual for some | |
85 | initial documentation. | |
86 | ||
87 | To 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 | ||
90 | The buffer-local variable `bidi-paragraph-direction', if non-nil, | |
91 | forces each paragraph in the buffer to have its base direction | |
92 | according to the value of this variable. Possible values are | |
93 | `right-to-left' and `left-to-right'. If the value is nil (the | |
94 | default), Emacs determines the base direction of each paragraph from | |
95 | its text, as specified by the Unicode Bidirectional Algorithm. | |
96 | ||
d20e1419 EZ |
97 | The function `current-bidi-paragraph-direction' returns the actual |
98 | value of paragraph base direction at point. | |
99 | ||
f4b6ba46 EZ |
100 | Reordering of bidirectional text for display in Emacs is a "Full |
101 | bidirectionality" class implementation of the Unicode Bidirectional | |
102 | Algorithm. | |
103 | ||
46759717 EZ |
104 | Note that some advanced display features, such as overlay strings and |
105 | `display' text properties, do not yet work correctly when | |
106 | bidirectional text is reordered for display. | |
107 | ||
303500aa | 108 | ** GTK scroll-bars are now placed on the right by default. |
52834b6b CY |
109 | Use `set-scroll-bar-mode' to change this. |
110 | ||
20fe03ad | 111 | ** GTK tool bars can have just text, just images or images and text. |
d8004abe | 112 | Customize `tool-bar-style' to choose style. On a Gnome desktop, the default |
20fe03ad JD |
113 | is 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. |
116 | The frame-parameter tool-bar-position controls this. It takes the values | |
1c0d77cc | 117 | top, left, right or bottom. The Options => Show/Hide menu has entries |
8b2dd508 JD |
118 | for this. |
119 | ||
8740c12d | 120 | ** ImageMagick support. |
b2fa3a09 GM |
121 | It is now possible to use the ImageMagick library to load many new |
122 | image formats in Emacs. By default, Emacs links with the ImageMagick | |
123 | libraries if they are present at build time. To disable this, use | |
8ea189f7 | 124 | the configure option `--without-imagemagick'. |
16a91140 | 125 | |
8740c12d GM |
126 | The new function `imagemagick-types' returns a list of image file |
127 | extensions that your installation of ImageMagick supports. The | |
128 | function `imagemagick-register-types' enables ImageMagick support for | |
b2957ea8 | 129 | these image types, minus those listed in `imagemagick-types-inhibit'. |
16a91140 | 130 | |
8740c12d | 131 | See 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 |
134 | theme when Emacs is built with GTK. | |
135 | ||
aa1859f5 J |
136 | ** Emacs uses GTK tooltips by default if built with GTK. You can turn that |
137 | off by customizing x-gtk-use-system-tooltips. | |
138 | ||
1ecb2d3f | 139 | ** Lucid menus and dialogs can display antialiased fonts if Emacs is built |
a6ac7fc4 JD |
140 | with Xft. To change font, use X resource faceName, for example: |
141 | Emacs.pane.menubar.faceName: Courier-12 | |
142 | Set 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 | |
146 | If a character has no glyphs in any of the available fonts, Emacs by | |
147 | default will display it either as a hexadecimal code in a box or as a | |
148 | thin 1-pixel space. In addition to these two methods, Emacs can | |
149 | display these characters as empty box, as an acronym, or not display | |
150 | them at all. To change how these characters are displayed, customize | |
151 | the variable `glyphless-char-display-control'. | |
152 | ||
153 | On character terminals these methods are used for characters that | |
154 | cannot 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. |
159 | This requires Emacs to be linked with libselinux at build time. | |
160 | ||
d8004abe GM |
161 | *** Emacs preserves the SELinux file context when backing up, and |
162 | optionally when copying files. To this end, copy-file has an extra | |
163 | optional argument, and backup-buffer and friends include the SELinux | |
164 | context in their return values. | |
b7d65a5f GM |
165 | |
166 | *** The new functions file-selinux-context and set-file-selinux-context | |
167 | get and set the SELinux context of a file. | |
168 | ||
a5bee597 MA |
169 | *** Tramp offers handlers for file-selinux-context and set-file-selinux-context |
170 | for remote machines which support SELinux. | |
171 | ||
9c524fcb | 172 | ** The function kill-emacs is now run upon receipt of the signals SIGTERM |
383ebd15 | 173 | and 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 |
179 | of buffer at first key-press (instead moves to top/bottom of buffer) | |
180 | when 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' |
183 | scroll a line instead of full screen. | |
184 | ||
a4b000fb | 185 | ** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 186 | define 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 | |
191 | trashing. This avoids inadvertently trashing temporary files. | |
192 | ||
193 | *** Calling `delete-file' or `delete-directory' with a prefix argument | |
194 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
195 | ||
f0bf7c8e JL |
196 | ** New option `list-colors-sort' defines the color sort order |
197 | for `list-colors-display'. | |
198 | ||
44198b6e CY |
199 | ** An Emacs Lisp package manager is now included. |
200 | This is a convenient way to download and install additional packages, | |
42d9cffa | 201 | from a package repository at elpa.gnu.org. |
cb6c4991 CY |
202 | |
203 | *** `M-x list-packages' shows a list of packages, which can be | |
204 | selected 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 | |
209 | automatically when Emacs starts up. To disable this, set | |
210 | `package-enable-at-startup' to nil. To change which packages are | |
211 | loaded, customize `package-load-list'. | |
212 | ||
d221e780 CO |
213 | ** An Emacs Lisp testing tool is now included. |
214 | Emacs Lisp developers can use this tool to write automated tests for | |
215 | their code. See the ERT info manual for details. | |
216 | ||
f065864f CY |
217 | ** Custom Themes |
218 | ||
219 | *** `M-x customize-themes' lists Custom themes which can be enabled. | |
220 | ||
782b5e8d CY |
221 | *** New option `custom-theme-load-path' is the load path for themes. |
222 | Emacs no longer looks for custom themes in `load-path'. The default | |
223 | is to search in `custom-theme-directory', followed by a built-in theme | |
224 | directory named "themes/" in `data-directory'. | |
225 | ||
b7617f6d CY |
226 | *** New option `custom-safe-themes' records known-safe theme files. |
227 | If a theme is not in this list, Emacs queries before loading it, and | |
228 | offers to save the theme to `custom-safe-themes' automatically. By | |
229 | default, all themes included in Emacs are treated as safe. | |
278f6845 | 230 | |
4ddf410a MA |
231 | ** The user option `remote-file-name-inhibit-cache' controls whether |
232 | the remote file-name cache is used for read access. | |
233 | ||
17284e30 GM |
234 | ** The standalone programs lib-src/digest-doc and sorted-doc have been |
235 | replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'. | |
236 | ||
f13183cf CY |

243 | ** There is a new command `count-words-region', which does what you expect. | |
244 | ||
67027b49 | 245 | ** completion-at-point now handles tags and semantic completion. |
a982c7ec | 246 | |
d74cba8f MA |
247 | ** The default value of `backup-by-copying-when-mismatch' is now t. |
248 | ||
1c708c1a CY |
249 | ** The command `just-one-space' (C-SPC), if given a negative argument, |
250 | also deletes newlines around point. | |
251 | ||
b9229673 CY |
252 | ** Deletion changes |
253 | ||
254 | *** New option `delete-active-region'. | |
255 | If non-nil, C-d, [delete], and DEL delete the region if it is active | |
256 | and no prefix argument is given. If set to `kill', these commands | |
257 | kill instead. | |
258 | ||
259 | *** New command `delete-forward-char', bound to C-d and [delete]. | |
42d9cffa CY |
260 | This is meant for interactive use, and obeys `delete-active-region'. |
261 | The command `delete-char' does not obey `delete-active-region'. | |
b9229673 CY |
262 | |
263 | *** `delete-backward-char' is now a Lisp function. | |
264 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
265 | However, the byte compiler now warns if it is called from Lisp; you | |
266 | should use delete-char with a negative argument instead. | |
267 | ||
268 | *** The option `mouse-region-delete-keys' has been deleted. | |
269 | ||
f9d71b42 CY |
270 | ** Selection changes. |
271 | ||
b1ab31ae CY |
272 | The default handling of clipboard and primary selections was changed |
273 | to conform with modern X applications. In short, most commands for | |
274 | killing and yanking text now use the clipboard, while mouse commands | |
275 | use the primary selection. | |
276 | ||
277 | In the following, we provide a list of these changes, followed by a | |
278 | list of steps to get the old behavior back if you prefer that. | |
279 | ||
280 | *** `mouse-drag-copy-region' now defaults to nil. | |
281 | *** `select-active-regions' now defaults to t. | |
282 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
283 | the kill-ring. The selected text is put in the primary selection, if | |
284 | the system possesses a separate primary selection facility (e.g. X). | |
285 | ||
286 | **** `select-active-regions' also accepts a new value, `only'. | |
287 | This means to only set the primary selection for temporarily active | |
288 | regions (usually made by mouse-dragging or shift-selection); | |
289 | "ordinary" active regions, such as those made with C-SPC followed by | |
290 | point motion, do not alter the primary selection. | |
291 | ||
292 | *** mouse-2 is now bound to `mouse-yank-primary'. | |
293 | This pastes from the primary selection, ignoring the kill-ring. | |
294 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
295 | ||
296 | *** `x-select-enable-clipboard' now defaults to t on all platforms. | |
297 | *** `x-select-enable-primary' now defaults to nil. | |
298 | Thus, commands that kill text or copy it to the kill-ring (such as | |
299 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
300 | ||
301 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now | |
302 | exactly equivalent to, respectively M-w, C-w, and C-y. | |
303 | ||
304 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already | |
305 | non-nil by default, as Windows does not support the primary selection | |
306 | between applications. | |
307 | ||
308 | *** To return to the previous behavior, do the following: | |
309 | ||
310 | **** Change `mouse-drag-copy-region' to t. | |
311 | **** Change `x-select-enable-primary' to t (on X only). | |
312 | **** Change `x-select-enable-clipboard' to nil. | |
313 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 314 | |
084e6df3 JD |
315 | *** Support for X cut buffers has been removed. |
316 | ||
99f053cf JA |
317 | ** New command `rectangle-number-lines', bound to `C-x r N', numbers |
318 | the lines in the current rectangle. With an prefix argument, this | |
319 | prompts for a number to count from and for a format string. | |

8a8d54cd VD |
344 | ** ERC changes |
345 | ||
346 | *** New vars `erc-autojoin-timing' and `erc-autojoin-delay'. | |
347 | If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a | |
348 | successful NickServ identification, or after `erc-autojoin-delay' | |
349 | seconds. The default value, 'ident, means to autojoin immediately | |
350 | after connecting. | |
351 | ||
5c0c0f77 LMI |
352 | *** New variable `erc-coding-system-precedence': If we use `undecided' |
353 | as the server coding system, this variable will then be consulted. | |
354 | The default is to decode strings that can be decoded as utf-8 as | |
355 | utf-8, and do the normal `undecided' decoding for the rest. | |
356 | ||
c0e505e5 CY |
357 | ** Eshell changes |
358 | ||
359 | *** The default value of eshell-directory-name is a directory named | |
360 | "eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory | |
361 | exists, that is used instead. | |
362 | ||
27d3cd56 CY |
363 | ** In ido-mode, C-v is no longer bound to ido-toggle-vc. |
364 | The reason is that this interferes with cua-mode. | |

413 | ** SQL Mode enhancements. |
414 | ||
30c4d8dc MM |
415 | *** Several variables have been marked as safe local variables. The |
416 | variables `sql-product', `sql-user', `sql-server', `sql-database' and | |
417 | `sql-port' can now be safely used as local variables. | |
7492acc9 | 418 | |
9250002f MM |
419 | *** `sql-dialect' is a synonym for `sql-product'. |
420 | ||
74790210 | 421 | *** Added ability to login with a port on MySQL and Postgres. |
7492acc9 | 422 | The custom variable `sql-port' can be specified for connection to |
74790210 MM |
423 | MySQL or Postgres servers. By default, the port is not listed in |
424 | either login parameter, but will be added to the command line if set | |
425 | to a non-zero value. | |
7492acc9 | 426 | |
9250002f MM |
427 | *** Dynamic selection of product in an SQL interactive session. |
428 | If you use `sql-product-interactive' to start an SQL interactive | |
429 | session it uses the current value of `sql-product'. Preceding the | |
430 | invocation with C-u will force it to ask for the product before | |
431 | creating the session. | |
432 | ||
433 | *** Renaming a SQL interactive buffer when it is created. | |
434 | Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres', | |
435 | `sql-mysql', etc.) with C-u will force a new interactive session to be | |
436 | started and will prompt for the new name. This will reduce the need | |
437 | for `sql-rename-buffer' is most common use cases. | |
438 | ||
3bd2cfef MM |
439 | *** Command continuation prompts in SQL interactive mode are suppressed. |
440 | Multiple line commands in SQL interactive mode, generate command | |
441 | continuation prompts which needlessly confuse the output. These | |
442 | prompts are now filtered out from the output. This change impacts | |
443 | multiple line SQL statements entered with C-j between each line, | |
444 | statements yanked into the buffer and statements sent with | |
445 | `sql-send-*' functions. | |
446 | ||
7492acc9 MM |
447 | *** Custom variables control prompting for login parameters. |
448 | Each supported product has a custom variable `sql-*-login-params' | |
449 | which is a list of the parameters to be prompted for before a | |
450 | connection is established. | |
451 | ||
74790210 MM |
452 | The lists consist of the following five tokens: `user', `password', |
453 | `database', `server', and `port'. The order in which they appear is | |
454 | the order in which they are prompted. The tokens symbols can be | |
455 | replaced by a sublist starting with the token and followed by a plist | |
456 | which control the prompting for values. The tokens `user', | |
457 | `database', and `server' each can take a property of :default which | |
458 | specifies the value to be used if no value is entered. The | |
459 | `database', `server', and `port' tokens handle the :completion | |
460 | property which restricts the entry to either one of the values in the | |
461 | list or to one of the values returned by the function provided as the | |
462 | property value. The `database' and `server' tokens also accept the | |
463 | :file property whose value is a regexp to identify useful file names. | |
464 | ||
465 | (user :default DEF) | |
466 | (database :default DEF | |
467 | :file FILEPAT | |
468 | :completion COMPLETE) | |
469 | (server :default DEF | |
470 | :file FILEPAT | |
471 | :completion COMPLETE) | |
472 | ||
473 | The FILEPAT when :file is specified is a regexp that will match valid | |
474 | file names (without the directory portion). Generally these strings | |
475 | will be of the form ".+\.SUF" where SUF is the desired file suffix. | |
476 | ||
477 | When :completion is specified, the COMPLETE corresponds to the | |
478 | PREDICATE argument to the `completing-read' function (a list of | |
479 | possible values or a function returning such a list). | |
5474c40f | 480 | |
30c4d8dc MM |
481 | *** Added `sql-connection-alist' to record login parameter values. |
482 | An alist for recording different username, database and server | |
483 | values. If there are multiple databases that you connect to the | |
484 | parameters needed can be stored in this alist. | |
485 | ||
486 | For example, the following might be set in the user's init.el: | |
487 | ||
488 | (setq sql-connection-alist | |
489 | '((dev (sql-product 'sqlite) | |
490 | (sql-database "/home/mmaug/dev.db")) | |
491 | (prd (sql-product 'oracle) | |
492 | (sql-user "mmaug") | |
493 | (sql-database "iprd2a")))) | |
494 | ||
495 | This defines two connections named "dev" and "prd". | |
496 | ||
497 | *** Added `sql-connect' to use predefined connections. | |
498 | Sets the login parameters based on the values in the | |
499 | `sql-connection-alist' and start a SQL interactive session. Any | |
500 | values specified in the connection will not be prompted for. | |
501 | ||
502 | In the example above, if the user were to invoke M-x sql-connect, they | |
503 | would be prompted for the connection. The user can respond with | |
504 | either "dev" or "prd". The "dev" connection would connect to the | |
505 | SQLite database without prompting; the "prd" connection would prompt | |
506 | for the users password and then connect to the Oracle database. | |
507 | ||
d26b0ea9 | 508 | **** Added SQL->Start... submenu when connections are defined. |
b2957ea8 | 509 | When connections have been defined, there is a submenu available that |
d26b0ea9 MM |
510 | allows the user to select one to start a SQLi session. The "Start |
511 | SQLi Session" item moves to the "Start..." submenu when cnnections | |
512 | have been defined. | |
513 | ||
514 | **** Added "Save Connection" menu item in SQLi buffers. | |
515 | When a SQLi session is not started by a connection then | |
516 | `sql-save-connection' will gather the login params specified for the | |
517 | session and save them as a new connection. | |
518 | ||
74790210 MM |
519 | *** List database objects and details. |
520 | Once a SQL interactive session has been started, you can get a list of | |
521 | the objects in the database and see details of those objects. The | |
522 | objects shown and the details available are product specific. | |
523 | ||
524 | **** List all objects. | |
525 | Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all | |
526 | objects" will list all the objects in the database. At a minimum it | |
527 | lists the tables and views in the database. Preceeding the command by | |
528 | universal argument may provide additional details or extend the | |
529 | listing to include other schemas objects. The list will appear in a | |
530 | separate window in view-mode. | |
531 | ||
532 | **** List Table details. | |
533 | Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table | |
534 | details" will ask for the name of a database table or view and display | |
535 | the list of columns in the relation. Preceeding the comand with the | |
536 | universal argument may provide additional details about each column. | |
537 | The list will appear in a separate window in view-mode. | |
538 | ||
7492acc9 MM |
539 | *** Added option `sql-send-terminator'. |
540 | When set makes sure that each command sent with `sql-send-*' commands | |
541 | are properly terminated and submitted to the SQL processor. | |
542 | ||
543 | *** Added option `sql-oracle-scan-on'. | |
544 | When set commands sent to Oracle's SQL*Plus are scanned for strings | |
30c4d8dc MM |
545 | starting with an ampersand and the user is asked for replacement text. |
546 | In general, the SQL*Plus option SCAN should always be set OFF under | |
547 | SQL interactive mode and this option used in its place. | |
7492acc9 MM |
548 | |
549 | *** SQL interactive mode will replace tabs with spaces. | |
550 | This prevents the comand interpretter for MySQL and Postgres from | |
551 | listing object name completions when being sent text via | |
552 | `sql-send-*' functions. | |
553 | ||
554 | *** An API for manipulating SQL product definitions has been added. | |
555 | ||
723ee192 SM |

3c3d4f5b MA |
572 | *** dbus-register-{service,method,property} |
573 | The -method and -property functions do not automatically register | |
574 | names anymore. | |
575 | ||
576 | The new function dbus-register-service registers a service known name | |
577 | on a D-Bus without simultaneously registering a property or a method. | |

0c32ce32 CY |
586 | ** VC and related modes |
587 | ||
588 | *** Support for pulling on distributed version control systems. | |
589 | The vc-update command now runs a "pull" operation, if it is supported. | |
590 | This updates the current branch from upstream. A prefix argument | |
591 | means to prompt the user for command specifics, e.g. a pull location. | |
592 | ||
593 | **** vc-pull is an alias for vc-update. | |
594 | ||
595 | **** Currently supported by Bzr. | |
596 | ||
597 | *** Support for merging on distributed version control systems. | |
598 | The vc-merge command now runs a "merge" operation, if it is supported. | |
599 | This merges another branch into the current one. A prefix argument | |
600 | means to prompt the user for command specifics, e.g. a merge location. | |

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