28 | ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
29 | to configure. Note that other libraries used by Emacs, RSVG and GConf, | |
30 | also depend on Gtk+. You can disable them with --without-rsvg and | |
31 | --without-gconf. | |
338648ad GM |
32 | |
33 | --- | |
31fd3586 GM |
34 | ** Emacs can be compiled with GnuTLS support. |
35 | This happens by default if a suitably recent version of the library is | |
36 | found at build time. To prevent this, use the configure option | |
37 | `--without-gnutls'. See below for GnuTLS features. | |
338648ad | 38 | |
aded53ff | 39 | --- |
31fd3586 GM |
40 | ** Emacs can be compiled with SELinux support. |
41 | This happens by default if a suitably recent version of the library is | |
42 | found at build time. To prevent this, use the configure option | |
43 | `--without-selinux'. See below for SELinux features. | |
aded53ff | 44 | |
e547b051 | 45 | --- |
31fd3586 GM |
46 | ** Emacs can be compiled with ImageMagick support. |
47 | This happens by default if a suitably recent version of the library is | |
48 | found at build time. To prevent this, use the configure option | |
49 | `--without-imagemagick'. See below for ImageMagick features. | |
c1f10868 | 50 | This feature is not available for the Nextstep or MS ports. |
d9170db5 | 51 | |
043efd56 GM |

53 | ** Emacs can be compiled with libxml2 support. | |
54 | This happens by default if a suitably recent version of the library is | |
55 | found at build time. To prevent this, use the configure option | |
56 | `--without-xml2'. See below for libxml2 features. | |

7d301ae6 CY |
59 | ** By default, the installed Info and man pages are compressed. |
60 | You can disable this by configuring --without-compress-info. | |
61 | ||
62 | --- | |
63 | ** New configure option --with-wide-int. | |
81eafe29 | 64 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. |
0a768890 PE |
65 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB |
66 | to about 2 GiB. | |
81eafe29 | 67 | |
d064e6a6 | 68 | --- |
7d301ae6 | 69 | ** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost. |
31fd3586 GM |
70 | These provide no new functionality, they just remove the need to edit |
71 | lib-src/Makefile by hand in order to use the associated features. | |
72 | ||
73 | --- | |
7d301ae6 | 74 | ** New configure option --enable-use-lisp-union-type. |
31fd3586 GM |
75 | This is only useful for Emacs developers to debug certain types of bugs. |
76 | This is not a new feature; only the configure flag is new. | |
041d709f | 77 | |
ddb54206 | 78 | --- |
041d709f CY |
79 | ** The standalone programs digest-doc and sorted-doc are removed. |
80 | Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'. | |
81 | ||
82 | --- | |
83 | ** The standalone program `fakemail' is removed. | |
84 | If you need it, feedmail.el provides a superset of the functionality. | |

eb199145 | 87 | * Startup Changes in Emacs 24.1 |
4a263588 | 88 | |
fdeb32ec | 89 | --- |
198a7a97 | 90 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte |
adbf62ff GM |
91 | command line arguments, and the EMACS_UNIBYTE environment variable, no |
92 | longer have any effect. (They were declared obsolete in Emacs 23.) | |
198a7a97 | 93 | |
fdeb32ec | 94 | +++ |
66b7b0fe | 95 | ** New command line option `--no-site-lisp' removes site-lisp directories |
1b5e5b0c GM |
96 | from load-path. -Q now implies this. This option does not affect the |
97 | EMACSLOADPATH environment variable (and hence has no effect for | |
c8d59ba3 | 98 | Nextstep builds). |

eb199145 | 101 | * Changes in Emacs 24.1 |
7841339b | 102 | |
a2a25d24 | 103 | ** Completion |
fdeb32ec | 104 | |
7d301ae6 | 105 | *** Shell mode uses pcomplete rules, with the standard completion UI. |
3d992aa0 | 106 | +++ |
de0bde62 CY |
107 | *** Many packages have been changed to use `completion-at-point' |
108 | rather than their own completion code. | |
3d992aa0 | 109 | +++ |
de0bde62 | 110 | *** `completion-at-point' now handles tags and semantic completion. |
27a16462 | 111 | --- |
a2a25d24 SM |
112 | *** Completion in a non-minibuffer now tries to detect the end of completion |
113 | and pops down the *Completions* buffer accordingly. | |
de09aa52 | 114 | +++ |
7d301ae6 | 115 | *** Completion can cycle, depending on `completion-cycle-threshold'. |
27a16462 | 116 | +++ |
a2a25d24 | 117 | *** New completion style `substring'. |
939db9ac | 118 | +++ |
620c53a6 | 119 | *** Completion style can be set per-category `completion-category-overrides'. |
939db9ac | 120 | +++ |
620c53a6 | 121 | *** Completion of buffers now uses substring completion by default. |
fb5b8aca CY |
122 | --- |
123 | *** The `widget-complete-field' option has been removed. | |
620c53a6 | 124 | |
6870aaef | 125 | ** Mail changes |
b30941db | 126 | +++ |
7d301ae6 CY |
127 | *** The first time you try sending mail, Emacs asks for a mail method. |
128 | This is implemented by a new default for `send-mail-function', which | |
129 | is `sendmail-query-once'. This offers to use the smtpmail package, or | |
130 | to use the old defaults relying on external mail facilities | |
131 | (`sendmail-send-it' on GNU/Linux and other Unix-like systems, and | |
132 | `mailclient-send-it' on Windows). | |
9f26dc24 | 133 | +++ |
7d301ae6 CY |
134 | *** Typing C-c m in the buffer made by M-x report-emacs-bug transfers |
135 | the report to your desktop's preferred mail client, if there is one. | |
136 | This uses either the "xdg-email" utility, or Mac OS's "open" command. | |
c3760c17 | 137 | --- |
7d301ae6 CY |
138 | *** See Changes in Specialized Modes and Packages for SMTPmail changes |
139 | and Mail mode changes | |
3f88cd72 | 140 | |
041d709f | 141 | ** Emacs server and client changes |
ddb54206 | 142 | +++ |
7d301ae6 | 143 | *** New option `server-port' specifies the port for TCP Emacs servers. |
041d709f CY |
144 | +++ |
145 | *** New emacsclient argument -q/--quiet suppresses some status messages. | |
146 | +++ | |
7d301ae6 CY |
147 | *** New emacsclient argument --frame-parameters specifies the frame |
148 | parameters of any newly-created graphical frame. | |
041d709f | 149 | +++ |
8350f087 | 150 | *** If emacsclient shuts down as a result of Emacs signaling an |
041d709f CY |
151 | error, its exit status is 1. |
152 | +++ | |
153 | *** New emacsclient argument --parent-id ID. | |
154 | This opens a client frame in parent X window ID, via XEmbed, similar | |
155 | to the --parent-id argument to Emacs. | |
156 | ||
d0ce9f8c MB |
157 | ** Internationalization changes |
158 | ||
f4b6ba46 | 159 | +++ |
d0ce9f8c | 160 | *** Emacs now supports display and editing of bidirectional text. |
7d301ae6 CY |
161 | Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are |
162 | displayed in the correct visual order as expected by users of those | |
163 | scripts. This display reordering is a "full bidirectionality" class | |
164 | implementation of the Unicode Bidirectional Algorithm. Buffers with | |
165 | no RTL text should look exactly the same as before. | |
f4b6ba46 | 166 | |
041d709f CY |
167 | +++ |
168 | **** New buffer-local variable `bidi-display-reordering'. | |
7d301ae6 | 169 | To disable display reordering in a buffer, change this to nil. |
d20e1419 | 170 | |
041d709f CY |
171 | +++ |
172 | **** New buffer-local variable `bidi-paragraph-direction'. | |
173 | If nil (the default), Emacs determines the base direction of each | |
174 | paragraph from its text, as specified by the Unicode Bidirectional | |
7d301ae6 CY |
175 | Algorithm. Setting the value to `right-to-left' or `left-to-right' |
176 | forces a base direction on each paragraph. | |
f4b6ba46 | 177 | |
7d301ae6 CY |
178 | Paragraphs with right-to-left base direction are displayed starting at |
179 | the right window edge. | |
f1816485 | 180 | |
d0ce9f8c | 181 | +++ |
041d709f CY |
182 | *** Enhanced support for characters with no glyphs in available fonts. |
183 | If a character has no glyphs in any of the available fonts, Emacs | |
184 | normally displays it either as a hexadecimal code in a box or as a | |
d0ce9f8c MB |
185 | thin 1-pixel space. In addition to these two methods, Emacs can |
186 | display these characters as empty box, as an acronym, or not display | |
187 | them at all. To change how these characters are displayed, customize | |
188 | the variable `glyphless-char-display-control'. | |
189 | ||
041d709f | 190 | On character terminals, these methods are used for characters that |
d0ce9f8c MB |
191 | cannot be encoded by the `terminal-coding-system'. |
192 | ||
ddb54206 | 193 | --- |
7d301ae6 | 194 | *** New input methods: farsi, farsi-translit, bulgarian-alt-phonetic. |
041d709f | 195 | |
939db9ac CY |
196 | +++ |
197 | *** `nobreak-char-display' now also highlights Unicode hyphen chars | |
198 | (U+2010 and U+2011). | |
199 | ||
31fd3586 | 200 | --- |
7d301ae6 | 201 | *** New Hebrew translation of the Emacs Tutorial. |
31fd3586 GM |
202 | Type `C-u C-h t' to choose it in case your language setup doesn't |
203 | automatically select it. | |
204 | ||
7d301ae6 CY |
205 | ** An Emacs Lisp package manager is now included. |
206 | This is a convenient way to download and install additional packages, | |
207 | from a package repository at http://elpa.gnu.org. | |
da97a9e6 | 208 | +++ |
7d301ae6 CY |
209 | *** M-x list-packages shows a list of packages, which can be |
210 | selected for installation. | |
d366bd53 | 211 | +++ |
7d301ae6 | 212 | *** New command `describe-package', bound to `C-h P'. |
d366bd53 | 213 | +++ |
7d301ae6 CY |
214 | *** By default, all installed packages are loaded automatically when |
215 | Emacs starts up. To disable this, set `package-enable-at-startup' to | |
216 | nil. To specify the packages to load, customize `package-load-list'. | |
16a91140 | 217 | |
7d301ae6 | 218 | ** Custom Themes |
35137ed3 | 219 | +++ |
7d301ae6 CY |
220 | *** New command `M-x customize-themes', which provides a convenient |
221 | interface for enabling and disabling Custom themes. | |
21100e7d | 222 | +++ |
7d301ae6 CY |
223 | *** New option `custom-theme-load-path' is the load path for themes. |
224 | Emacs no longer looks for custom themes in `load-path'. The default | |
225 | is to search in `custom-theme-directory', followed by a built-in theme | |
226 | directory named "themes/" in `data-directory'. | |
a49ca6b9 | 227 | +++ |
7d301ae6 CY |
228 | *** New option `custom-safe-themes' records known-safe theme files. |
229 | If a theme is not in this list, Emacs queries before loading it, and | |
230 | offers to save the theme to `custom-safe-themes' automatically. By | |
231 | default, all themes included in Emacs are treated as safe. | |
b7d65a5f | 232 | |
7d301ae6 | 233 | ** Improved GTK integration |
a49ca6b9 | 234 | +++ |
7d301ae6 CY |
235 | *** GTK scroll-bars are now placed on the right by default. |
236 | Use `set-scroll-bar-mode' to change this. | |
a49ca6b9 | 237 | +++ |
7d301ae6 CY |
238 | *** GTK tool bars can have just text, just images or images and text. |
239 | Customize `tool-bar-style' to choose style. On a Gnome desktop, the | |
240 | default is taken from desktop settings. | |
241 | --- | |
242 | *** GTK tool bars can be placed on the left/right or top/bottom of the frame. | |
243 | The frame-parameter tool-bar-position controls this. It takes the | |
244 | values top, left, right or bottom. The Options => Show/Hide menu has | |
245 | entries for this. | |
246 | +++ | |
247 | *** The default colors for selected text (the `region' face) are taken | |
248 | from the GTK theme when Emacs is built with GTK. | |
249 | +++ | |
250 | *** Emacs uses GTK tooltips by default if built with GTK. | |
251 | You can disable this by changing `x-gtk-use-system-tooltips' to nil. | |
a5bee597 | 252 | |
7d301ae6 | 253 | ** Exiting changes |
ddb54206 | 254 | +++ |
7d301ae6 CY |
255 | *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP, |
256 | and also if it receives a SIGINT signal in batch mode. | |
ddb54206 | 257 | +++ |
7d301ae6 CY |
258 | *** `kill-emacs-hook' is now also run in batch mode. |
259 | Third-party code which adds to `kill-emacs-hook' should check if they | |
260 | do the right thing in batch mode. | |
9c524fcb | 261 | |
041d709f | 262 | ** Scrolling changes |
550f41cd | 263 | +++ |
041d709f | 264 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' |
0a19a6f8 | 265 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
7d301ae6 | 266 | of buffer at first key-press (instead they move to top/bottom of buffer) |
550f41cd | 267 | when `scroll-error-top-bottom' is non-nil. |
550f41cd CY |
268 | +++ |
269 | *** New variable `scroll-error-top-bottom' (see above). | |
e7a3ff06 | 270 | +++ |
041d709f | 271 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' |
5a97d2da | 272 | scroll a line instead of full screen. |
550f41cd | 273 | +++ |
041d709f | 274 | *** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 275 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
d0f69533 | 276 | +++ |
041d709f | 277 | *** If you customize `scroll-conservatively' to a value greater than 100, |
d0f69533 EZ |
278 | Emacs will never recenter point in the window when it scrolls due to |
279 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | |
280 | Previously, you needed to use `most-positive-fixnum' as the value of | |
281 | `scroll-conservatively' to achieve the same effect. | |
d0f69533 | 282 | --- |
7d301ae6 | 283 | *** "Aggressive" scrolling now honors the scroll margins. |
d0f69533 EZ |
284 | If you customize `scroll-up-aggressively' or |
285 | `scroll-down-aggressively' and move point off the window, Emacs now | |
286 | scrolls the window so as to avoid positioning point inside the scroll | |
287 | margin. | |
288 | ||
04e2ce72 | 289 | +++ |
7d301ae6 CY |
290 | ** Basic SELinux support has been added. |
291 | This requires Emacs to be linked with libselinux at build time. | |
f1a5d776 | 292 | |
05f77e38 | 293 | +++ |
7d301ae6 CY |
294 | *** Emacs preserves the SELinux file context when backing up, and |
295 | optionally when copying files. The function `copy-file' has an extra | |
296 | optional argument for preserving SELinux context, and the return value | |
297 | of `backup-buffer' now includes the SELinux context. | |
f0bf7c8e | 298 | |
d43f5a42 | 299 | +++ |
7d301ae6 CY |
300 | *** The new functions file-selinux-context and set-file-selinux-context |
301 | get and set the SELinux context of a file. | |
44198b6e | 302 | |
7d301ae6 | 303 | ** Trash changes |
b0d7d8af | 304 | +++ |
7d301ae6 CY |
305 | *** `delete-by-moving-to-trash' now only affects commands that specify |
306 | trashing. This avoids inadvertently trashing temporary files. | |
b0d7d8af | 307 | +++ |
7d301ae6 CY |
308 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
309 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
278f6845 | 310 | |
041d709f | 311 | ** File- and directory-local variable changes |
b8f82dc1 | 312 | +++ |
041d709f CY |
313 | *** You can stop directory local vars from applying to subdirectories. |
314 | Add an element (subdirs . nil) to the alist portion of any variables | |
315 | settings to indicate that the section should not apply to | |
316 | subdirectories. | |
89bd9ccd | 317 | +++ |
041d709f CY |
318 | *** Directory local variables can apply to some file-less buffers. |
319 | Affected modes include dired, vc-dir, and log-edit. For example, | |
320 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will | |
321 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call | |
322 | `hack-dir-local-variables-non-file-buffer' to support this. | |
041d709f CY |
323 | +++ |
324 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. | |
325 | Instead, use "eval: (minor-mode 1)". | |
c136e5cd | 326 | |
61086eb6 | 327 | +++ |
7b447e9b GM |
328 | *** The variable `inhibit-first-line-modes-regexps' has been renamed |
329 | to `inhibit-local-variables-regexps'. As the name suggests, it now | |
330 | applies to ALL file local variables, not just -*- mode ones. | |
331 | The associated `inhibit-first-line-modes-suffixes' has been renamed | |
332 | in the corresponding way. | |
333 | ||
7d301ae6 | 334 | ** Graphical interface changes |
fdeb32ec | 335 | +++ |
7d301ae6 CY |
336 | *** On graphical displays, the mode-line no longer ends in dashes. |
337 | Also, the first dash (which does not indicate anything) is just | |
338 | displayed as a space. | |
b22b1918 | 339 | --- |
5d907d6c DA |
340 | *** `menu-bar-select-buffer-function' lets you choose another operation |
341 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. | |
7d301ae6 CY |
342 | --- |
343 | *** Lucid menus and dialogs can display antialiased fonts if Emacs is | |
344 | built with Xft. These fonts can be set via X resources, for example: | |
345 | Emacs.pane.menubar.font: Courier-12 | |
346 | ||
347 | +++ | |
348 | ** New basic faces `error', `warning', `success'. | |
349 | These are used to highlight text indicating failure, caution or | |
350 | successful operation. | |
351 | ||
352 | +++ | |
353 | ** New option `list-colors-sort' defines the color sort order | |
354 | for `list-colors-display'. | |
355 | ||
356 | +++ | |
357 | ** The variable `focus-follows-mouse' now always defaults to nil. | |
5d907d6c | 358 | |
0a2132ba CY |
359 | ** Window changes |
360 | ||
361 | +++ | |

385 | *** New option `window-combination-resize'. |
386 | The new option `window-combination-resize' allows to split a window that | |
387 | otherwise cannot be split because it's too small by stealing space from | |
388 | other windows in the same combination. Subsequent resizing or deletion | |
389 | of the window will resize all windows in the same combination as well. | |

403 | This is handy for minibuffer-only frames, and is also used for the feature |
404 | where mouse-1 pops up *Messages*"', which can now easily be changed. | |

433 | *** M-= is bound to `count-words-region', not `count-lines-region'. | |
434 | The `count-words-region' command, when called interactively, reports | |
435 | the number of lines, words, and characters in the region. It is a | |
436 | superset of the old `count-lines-region', which is now an obsolete | |
437 | alias for it. | |

ec9da840 | 440 | ** The command `just-one-space' (M-SPC), if given a negative argument, |

b9229673 | 445 | *** New option `delete-active-region'. |
ddb54206 CY |
446 | If non-nil, [delete] and DEL delete the region if it is active and no |
447 | prefix argument is given. If set to `kill', these commands kill | |
448 | instead. | |
50b063c3 | 449 | +++ |
59ee0542 | 450 | *** New command `delete-forward-char', bound to [delete]. |
42d9cffa CY |
451 | This is meant for interactive use, and obeys `delete-active-region'. |
452 | The command `delete-char' does not obey `delete-active-region'. | |
50b063c3 | 453 | --- |
b9229673 CY |
454 | *** `delete-backward-char' is now a Lisp function. |
455 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
7d301ae6 CY |
456 | However, the byte compiler now warns if it is called from Lisp; Lisp |
457 | callers should use delete-char with a negative argument instead. | |
ddb54206 | 458 | --- |
b9229673 CY |
459 | *** The option `mouse-region-delete-keys' has been deleted. |

f9d71b42 CY |
461 | ** Selection changes. |
462 | ||
7d301ae6 CY |
463 | The default handling of clipboard and primary selections has been |
464 | changed to conform with modern X applications. In short, most | |
465 | commands for killing and yanking text now use the clipboard, while | |
466 | mouse commands use the primary selection. | |
b1ab31ae CY |
467 | |
468 | In the following, we provide a list of these changes, followed by a | |
469 | list of steps to get the old behavior back if you prefer that. | |
470 | ||
963578d3 | 471 | +++ |
b1ab31ae CY |
472 | *** `select-active-regions' now defaults to t. |
473 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
963578d3 | 474 | the kill ring. The selected text is put in the primary selection, if |
b1ab31ae CY |
475 | the system possesses a separate primary selection facility (e.g. X). |
476 | ||
963578d3 | 477 | +++ |
b1ab31ae CY |
478 | **** `select-active-regions' also accepts a new value, `only'. |
479 | This means to only set the primary selection for temporarily active | |
480 | regions (usually made by mouse-dragging or shift-selection); | |
481 | "ordinary" active regions, such as those made with C-SPC followed by | |
482 | point motion, do not alter the primary selection. | |
483 | ||
963578d3 CY |
484 | --- |
485 | **** `mouse-drag-copy-region' now defaults to nil. | |
486 | ||
487 | +++ | |
b1ab31ae CY |
488 | *** mouse-2 is now bound to `mouse-yank-primary'. |
489 | This pastes from the primary selection, ignoring the kill-ring. | |
490 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
963578d3 | 491 | +++ |
b1ab31ae | 492 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
963578d3 | 493 | +++ |
b1ab31ae CY |
494 | *** `x-select-enable-primary' now defaults to nil. |
495 | Thus, commands that kill text or copy it to the kill-ring (such as | |
496 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
497 | ||
963578d3 | 498 | --- |
b1ab31ae CY |
499 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now |
500 | exactly equivalent to, respectively M-w, C-w, and C-y. | |
501 | ||
963578d3 | 502 | --- |
b1ab31ae CY |
503 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already |
504 | non-nil by default, as Windows does not support the primary selection | |
505 | between applications. | |
506 | ||
963578d3 | 507 | --- |
b1ab31ae | 508 | *** To return to the previous behavior, do the following: |
104c2fe9 | 509 | **** Change `select-active-regions' to nil. |
b1ab31ae CY |
510 | **** Change `mouse-drag-copy-region' to t. |
511 | **** Change `x-select-enable-primary' to t (on X only). | |
512 | **** Change `x-select-enable-clipboard' to nil. | |
513 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 514 | |
963578d3 | 515 | +++ |
084e6df3 | 516 | *** Support for X cut buffers has been removed. |
a08a07e3 | 517 | +++ |
3fd50d5c CY |
518 | *** X clipboard managers are now supported. |
519 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. | |
4b80f674 | 520 | |
50b063c3 | 521 | +++ |
99f053cf | 522 | ** New command `rectangle-number-lines', bound to `C-x r N', numbers |
6b2c221e | 523 | the lines in the current rectangle. With a prefix argument, this |
99f053cf JA |
524 | prompts for a number to count from and for a format string. |
525 | ||
6bf7006f | 526 | +++ |
7d301ae6 | 527 | ** `redisplay-dont-pause' now defaults to t. |
6bf7006f EZ |
528 | This makes Emacs feel more responsive to editing commands that arrive |
529 | at high rate, e.g. if you lean on some key, because stopping redisplay | |
530 | in the middle (when this variable is nil) forces more expensive | |
531 | updates later on, and Emacs appears to be unable to keep up. | |
532 | ||
e70b5064 CY |
533 | +++ |
534 | ** The behavior of <TAB> for active regions in Text mode has changed. | |
535 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | |
536 | when the region is active causes Emacs to indent all the lines in the | |
537 | region, aligning them with the line previous to the first line in the | |
538 | region (or with the left margin if there is no previous line). | |

1215 | Given a string containing characters from right-to-left (RTL) scripts, |

1217 | a buffer, such that any following text will be always displayed to the | |
7d301ae6 CY |

1237 | Many window handling functions like `split-window', `delete-window', or |
1238 | `delete-other-windows' as well as the window resizing functions can now | |
1239 | act on any window including internal ones. | |
c4682d18 MR |

1244 | names are provided as aliases. Two new functions `window-total-width' | |

1249 | behavior of a number of functions like `split-window', `delete-window' | |
ed6235ea MR |

1255 | set to any of the values 'below, 'right, 'above, or 'left to make the | |
1256 | new window appear on the corresponding side of the window that shall be | |
1257 | split. Any other value of SIDE will cause `split-window' to split the | |
1258 | window into two side-by-side windows as before. | |

1269 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | |
1270 | is able to resize other windows if a window adjacent to the trailing | |
1271 | edge cannot be shrunk any more. This makes its behavior more similar to | |
1272 | that of Emacs 21 without compromising, however, its inability to delete | |
1273 | windows which was introduced in Emacs 22. | |
c4682d18 MR |

1276 | Windows now have local buffer lists. This means that removing a buffer | |
1277 | from display in a window will preferably show the buffer previously | |
1278 | shown in that window with its previous window-start and window-point | |
1279 | positions. This also means that the same buffer may be automatically | |
1280 | shown twice even if it already appears in another window. | |

1460 | ||
04e2ce72 | 1461 | +++ |
7d301ae6 | 1462 | *** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
1463 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
1464 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
1465 | argument is supplied (see Trash changes, above). | |
53967e09 | 1466 | |
a34baa83 | 1467 | +++ |
7d301ae6 | 1468 | *** New file predicates: `file-equal-p', `file-in-directory-p'. |

f7c9199f | 1470 | +++ |
4039c786 CY |
1471 | ** Tool-bars can display separators. |
1472 | Tool-bar separators are handled like menu separators in menu-bar maps, | |
94975270 | 1473 | i.e. via menu entries of the form `(menu-item "--")'. |

1475 | ** Image API |
1476 | ||
eea14f31 | 1477 | +++ |
18af70d0 CY |
1478 | *** Animated images support (currently animated gifs only). |
1479 | ||
eea14f31 | 1480 | +++ |
18af70d0 CY |
1481 | **** `image-animated-p' returns non-nil if an image can be animated. |
1482 | ||
eea14f31 | 1483 | +++ |
18af70d0 CY |
1484 | **** `image-animate' animates a supplied image spec. |
1485 | ||
eea14f31 | 1486 | +++ |
18af70d0 CY |
1487 | **** `image-animate-timer' returns the timer object for an image that |
1488 | is being animated. | |
00fe2df1 | 1489 | |
7cb76fe0 GM |
1490 | --- |
1491 | *** `image-extension-data' has been renamed to `image-metadata'. | |
1492 | The old name is an obsolete alias to the new one. | |
1546c559 | 1493 | |
bba26374 | 1494 | +++ |
b4ac6e8c GM |
1495 | *** Image mode can view any image type that ImageMagick supports. |
1496 | This requires Emacs to be built with ImageMagick support. | |
7d301ae6 CY |
1497 | |
1498 | **** New function `imagemagick-types', defined if ImageMagick support | |
1499 | is enabled, returns a list of image file extensions that your | |
1500 | ImageMagick installation supports. | |
1501 | ||
1502 | **** New function `imagemagick-register-types' enables ImageMagick | |
1503 | image types in Image mode and in `create-image' and other helper | |
1504 | functions. | |
1505 | ||
1506 | **** New option `imagemagick-types-inhibit' excludes certain | |
1507 | ImageMagick image types from `imagemagick-register-types'. | |
1508 | ||
1509 | --- | |
1510 | **** With ImageMagick support, there are extra Image mode commands to | |
1511 | resize and rotate images: `image-transform-fit-to-height', | |
1512 | `image-transform-fit-to-width', `image-transform-set-rotation', and | |
1513 | `image-transform-set-scale'. | |

7d301ae6 CY |
1516 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
1517 | passes it to the mail user agent function. This argument specifies an | |
1518 | action for returning to the caller after finishing with the mail. For | |
1519 | example, this is used by Rmail to optionally delete a mail window. | |
b4ac6e8c | 1520 | |
483ab230 | 1521 | +++ |
71c17aec | 1522 | ** XML and HTML parsing |
483ab230 CY |
1523 | If Emacs is compiled with libxml2 support, there are two new |
1524 | functions: `libxml-parse-html-region' (which parses "real world" HTML) | |
1525 | and `libxml-parse-xml-region' (which parses XML). Both return an | |
1526 | Emacs Lisp parse tree. | |
4b9832a6 | 1527 | |
7d301ae6 | 1528 | ** Networking and encryption changes |
e2574f2c | 1529 | |
7d301ae6 CY |
1530 | +++ |
1531 | *** `open-network-stream' can now be used to open an encrypted stream. | |
1532 | It now accepts an optional `:type' parameter for initiating a TLS | |
1533 | connection, directly or via STARTTLS. To do STARTTLS, additional | |
1534 | parameters (`:end-of-command', `:success', `:capabilities-command') | |
1535 | must also be supplied. | |
1536 | ||
1537 | *** New library gnutls.el. | |
1538 | ||
1539 | If Emacs is built with GnuTLS support, the function | |
1540 | `gnutls-available-p' is defined and returns non-nil. The main entry | |
1541 | points are `open-gnutls-stream' and `gnutls-negotiate'. It's easiest | |
1542 | to use these functions through `open-network-stream', because that can | |
1543 | upgrade connections through STARTTLS opportunistically or use plain | |
1544 | SSL, depending on your needs. For debugging, set `gnutls-log-level' | |
1545 | greater than 0. | |
1546 | ||
1547 | +++ | |
1548 | *** New primitive `secure-hash' that supports many secure hash algorithms: | |
1549 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library | |
1550 | sha1.el has been removed. The `sha1' feature is provided by default. | |

1555 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. |
1556 | ||
ddb54206 | 1557 | +++ |
9326ba26 CY |
1558 | ** Progress reporters can now "spin". |
1559 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
1560 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
1561 | time you call `progress-reporter-update' on that progress reporter, | |
1562 | with a nil or omitted VALUE argument, the reporter message is | |
1563 | displayed with a "spinning bar". | |
1564 | ||
8f05da42 | 1565 | +++ |
3e214b50 JB |
1566 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is |
1567 | being reverted, even if the buffer has a local `revert-buffer-function'. | |
1568 | ||
3d439cd1 | 1569 | +++ |
001bf877 GM |
1570 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. |
1571 | If delayed-warnings-list is non-nil, the command loop calls | |
7d301ae6 CY |
1572 | `delayed-warnings-hook' after `post-command-hook'. At present, this |
1573 | is only used by Emacs on some platforms to display warnings during | |
1574 | startup, which might otherwise not be noticed. This uses the | |
1575 | functions `display-delayed-warnings' and `collapse-delayed-warnings'. | |
001bf877 | 1576 | |
6420d28b CY |
1577 | --- |
1578 | ** rx.el has a new `group-n' construct for explicitly numbered groups. | |
1579 | ||
dac86404 GM |
1580 | +++ |
1581 | ** New function `make-composed-keymap' that constructs a new keymap | |
1582 | from multiple input maps. You can use this to make a keymap that | |
1583 | inherits from multiple maps, eg: | |
1584 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) | |
43dc9f5b | 1585 | |
c8f6ec5c GM |
1586 | +++ |
1587 | ** New function `string-prefix-p'. | |
1588 | (This was actually added in Emacs 23.2 but was not advertised at the time.) | |
1589 | ||
ddb54206 | 1590 | +++ |
27f7ef2f | 1591 | ** New reader macro ## that stands for the empty symbol. |
43dc9f5b AS |
1592 | This means that the empty symbol can now be read back. Also, #: by itself |
1593 | (when not immediately followed by a possible symbol character) stands for | |
1594 | an empty uninterned symbol. | |
041d709f | 1595 | |
fead402d CY |
1596 | +++ |
1597 | ** New math functions `isnan', `copysign', `frexp', `ldexp'. | |
1598 | ||
7d301ae6 | 1599 | ** The following functions and variables are obsolete: |
041d709f | 1600 | |
05f77e38 GM |
1601 | --- |
1602 | *** `tooltip-use-echo-area' is obsolete. | |
1603 | Rather than setting this to t, disable Tooltip mode instead. | |
1604 | ||
34c99998 | 1605 | +++ |
041d709f CY |
1606 | *** buffer-substring-filters is obsolete. |
1607 | Use `filter-buffer-substring-functions' instead. | |
1608 | ||
7cb76fe0 | 1609 | --- |
041d709f CY |
1610 | *** `byte-compile-disable-print-circle' is obsolete. |
1611 | ||
f160676e | 1612 | --- |
041d709f | 1613 | *** `deferred-action-list' and `deferred-action-function' are obsolete. |
f160676e GM |
1614 | Use `post-command-hook' instead. |
1615 | ||
d366bd53 | 1616 | +++ |
67e729a5 CY |
1617 | *** `font-lock-maximum-size' is obsolete. |

7a22e700 | 1632 | *** --distfiles specifies files to be included in binary distribution. |
e2574f2c | 1633 | |
a0d363f4 | 1634 | +++ |
7a22e700 OK |
1635 | *** --without-gnutls disables automatic GnuTLS detection. |

1644 | ** The Lisp function `w32-default-color-map' is now obsolete. | |
1645 | (It is only used internally in the Emacs C code.) | |
5430d399 | 1646 | |
1f5e1a16 GM |
1647 | +++ |

1652 | ** On Mac OS X, dragging a file into Emacs visits the file, like on | |
1653 | other platforms, rather than inserting its contents into the buffer. | |
