17 | Temporary note: |
18 | +++ indicates that the appropriate manual has already been updated. | |
19 | --- means no change in the manuals is called for. | |
20 | When you add a new item, please add it without either +++ or --- | |
21 | so we will look at it and add it to the manual. | |

24 | * Installation Changes in Emacs 24.2 | |
b8df54ff PE |
25 | |
26 | ** New configure option '--enable-gcc-warnings', intended for developers. | |
27 | If building with GCC, this enables compile-time checks that warn about | |
28 | possibly-questionable C code. On a recent GNU system there should be | |
29 | no warnings; on older and on non-GNU systems the generated warnings | |
ae6e112d | 30 | may be useful. |
b8df54ff | 31 | |
a4a18b8b GM |
32 | --- |
33 | ** Emacs uses libtinfo in preference to libncurses, if available. | |
34 | ||
187e9b90 GM |
35 | --- |
36 | ** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and | |
37 | /usr/pkg/lib to the linker search path. You must add them yourself if | |
38 | you want them. | |

41 | * Startup Changes in Emacs 24.2 | |
e5fcdb5e GM |
42 | |
43 | ** Emacs no longer searches for `leim-list.el' files beneath the standard | |
44 | lisp/ directory. There should not be any there anyway. If you have | |
45 | been adding them there, put them somewhere else, eg site-lisp. | |

48 | * Changes in Emacs 24.2 | |
49 | ||
e5a36063 GM |
50 | ** New functions `system-users', `system-groups' return lists of the user |
51 | name, group names known to the system (where possible). | |
52 | ||
a1ed8b05 GM |
53 | ** If your Emacs was built from a bzr checkout, the new variable |
54 | `emacs-bzr-version' contains information about which bzr revision was used. | |
55 | ||
c505aaeb CY |
56 | ** ImageMagick support, if available, is automatically enabled. |
57 | It is no longer necessary to call `imagemagick-register-types' | |
58 | explicitly to install ImageMagick image types; that function is called | |
59 | automatically when setting `imagemagick-types-inhibit'. | |
60 | ||
61 | *** Setting `imagemagick-types-inhibit' to t now disables the use of | |
62 | ImageMagick to view images, set | |
63 | ||
de6ff46d CY |
64 | ** String values for `initial-buffer-choice' also apply to emacsclient |
65 | frames, if emacsclient is only told to open a new frame without | |
66 | specifying any file to visit or expression to evaluate. | |
67 | ||
dc0f75c8 GM |
68 | +++ |
69 | ** You can prevent the creation of lock files by setting `create-lockfiles' | |
70 | to nil. Use with caution, and only if you really need to. | |
71 | ||
b8a82b69 | 72 | +++ |
03794570 | 73 | ** Using "unibyte: t" in Lisp source files is obsolete. |
57699e37 | 74 | Use "coding: raw-text" instead. |

77 | * Editing Changes in Emacs 24.2 | |
c25df26e RT |
78 | |
79 | ** M-x move-to-column, if called interactively with no prefix arg, now | |
80 | prompts for a column number. | |
81 | ||
0f84437b TV |
82 | ** `mouse-avoidance-banish-position' can now be used to customize |
83 | `mouse-avoidance-mode' further. | |
84 | ||
09b95ce3 MY |
85 | ** `C-M-f' and `C-M-b' will now move to the path name separator |
86 | character when doing minibuffer filename prompts. | |
87 | ||
5dd1713e CY |
88 | ** `goto-char' is now bound to `M-g c'. |

91 | * Changes in Specialized Modes and Packages in Emacs 24.2 | |
b2459884 | 92 | |
d13c8be6 SM |
93 | ** reStructuredText mode |
94 | ||
95 | *** Major merge with upstream development. | |
96 | ||
97 | *** Nearly all keys are rebound making room for more keys and comply | |
98 | better to usage in other modes. Bindings are described with C-c C-h. | |
99 | ||
100 | *** Major revision of indentation. Now works very similar to other | |
101 | modes. TAB is your friend. | |
102 | ||
103 | *** Major revision of filling. Works fine with most of | |
104 | reStructuredText syntax. Auto-filling is also supported. | |
105 | ||
106 | *** Major revision of comment handling. | |
107 | ||
108 | *** Major revision of fontification. Now works with `jit-lock-mode'. | |
109 | Thanks to Stefan Monnier for help. | |
110 | ||
111 | *** reStructuredText syntax is covered more closely in many cases. | |
112 | Among other things this improves the experience for Sphinx users. | |
113 | ||
114 | *** `rst-insert-list' inserts new list or continues existing lists. | |
115 | Based on code by Wei-Wei Guo. | |
116 | ||
117 | *** Customization is extended, corrected and improved. | |
118 | ||
119 | *** Negative prefix argument always works for `rst-adjust'. | |
120 | ||
121 | *** Window configuration is reset after displaying TOC. | |
122 | ||
123 | *** There is a package version in `rst-version' | |
124 | ||
d81bd059 SM |
125 | ** New `derived-mode' filter for Ibuffer, bound to `/ M'. |
126 | `/ m' is now bound to filter by used-mode, which used to be bound to `/ M'. | |
c4cf6d91 | 127 | |
46c71e23 CY |
128 | ** Apropos |
129 | ||
130 | *** The faces used by Apropos are now directly customizable. | |
131 | These faces are named `apropos-symbol', `apropos-keybinding', and so on; | |
132 | see the `apropos' Custom group for details. | |
133 | ||
134 | **** The old options whose values specified faces to use were removed | |
135 | (i.e. `apropos-symbol-face', `apropos-keybinding-face', etc.). | |
136 | ||
48176e8b GM |
137 | ** Calendar |
138 | ||
03794570 GM |
139 | *** The calendars produced by cal-html include holidays. |
140 | Customize cal-html-holidays to change this. | |
48176e8b | 141 | |
cf20dee0 CY |
142 | ** Customize |
143 | ||
144 | *** `custom-reset-button-menu' now defaults to t. | |
ab036cd7 | 145 | |
775c916b CY |
146 | *** Non-option variables are never matched in `customize-apropos' and |
147 | `customize-apropos-options' (i.e. the prefix argument does nothing for | |
148 | these commands now). | |
149 | ||
b2459884 | 150 | ** erc will look up server/channel names via auth-source and use the |
29734c21 | 151 | channel keys found, if any. |
b2459884 | 152 | |
9f9aa044 CY |
153 | ** FFAP |
154 | ||
155 | *** The option `ffap-url-unwrap-remote' can now be a list of strings, | |
156 | specifying URL types which should be converted to remote file names at | |
157 | the FFAP prompt. The default is now '("ftp"). | |
158 | ||
782fbf2a CY |
159 | ** Follow mode |
160 | ||
161 | *** The obsolete variable `follow-mode-off-hook' has been removed. | |
162 | ||
163 | *** Follow mode no longer works by using advice. | |
164 | The option `follow-intercept-processes' has been removed. | |
165 | ||
29734c21 MN |
166 | ** The `server-auth-key' variable can be used to set a permanent |
167 | shared key for Emacs Server. | |
fc72b15c PO |
168 | |
169 | ** In Perl mode, new option `perl-indent-parens-as-block' causes non-block | |
170 | closing brackets to be aligned with the line of the opening bracket. | |
171 | ||
25a9a140 GM |
172 | ** FIXME something happened to ses.el, 2012-04-17. |
173 | ||
cf20dee0 CY |
174 | ** which-function-mode now applies to all applicable major modes by default. |
175 | ||
dcbf5805 MA |
176 | ** D-Bus |
177 | ||
178 | +++ | |
179 | *** New variables `dbus-compiled-version' and `dbus-runtime-version'. | |
180 | ||
181 | +++ | |
182 | *** The D-Bus object manager interface is implemented. | |
183 | ||
184 | +++ | |
185 | *** Variables of type :(u)int32 and :(u)int64 accept floating points, | |
186 | if their value does not fit into Emacs's integer range. | |
187 | ||
188 | +++ | |
189 | *** The function `dbus-call-method' works non-blocking now, it can be | |
190 | interrupted by C-g. `dbus-call-method-non-blocking' is obsolete. | |
191 | ||
192 | +++ | |
193 | *** Signals can be sent also as unicast message. | |
194 | ||
195 | +++ | |
196 | *** The argument list of `dbus-register-signal' has been extended, | |
197 | according to the new match rule types of D-Bus. See the manual for | |
198 | details. | |
199 | ||
200 | +++ | |
201 | *** `dbus-init-bus' supports private connections. | |
202 | ||
203 | +++ | |
204 | *** There is a new function `dbus-setenv'. | |
205 | ||
0268cf45 MA |
206 | +++ |
207 | ** notifications.el supports now version 1.2 of the Notifications API. | |
208 | The function `notifications-get-capabilities' returns the supported | |
209 | server properties. | |
210 | ||
6632d361 CY |
211 | ** Tabulated List and packages derived from it |
212 | ||
e5f9458f | 213 | *** New command `tabulated-list-sort', bound to `S', sorts the column |
6632d361 CY |
214 | at point, or the Nth column if a numeric prefix argument is given. |
215 | ||
ce7b18ec CY |
216 | ** URL |
217 | ||
218 | *** Structs made by `url-generic-parse-url' have nil `attributes' slot. | |
219 | Previously, this slot stored semicolon-separated attribute-value pairs | |
220 | appended to some imap URLs, but this is not compatible with RFC 3986. | |
221 | So now the `filename' slot stores the entire path and query components | |
222 | and the `attributes' slot is always nil. | |
223 | ||
224 | *** New function `url-encode-url' for encoding a URI string. | |
225 | The `url-retrieve' function now uses this to encode its URL argument, | |
226 | in case that is not properly encoded. | |
227 | ||
82f289a4 GM |
228 | ** Obsolete packages: |
229 | ||
797e6e88 SM |
230 | *** assoc.el |
231 | In most cases, assoc+member+push+delq work just as well. | |
232 | And in any case it's just a terrible package: ugly semantics, terrible | |
233 | inefficiency, and not namespace-clean. | |
234 | ||
3c74813a GM |
235 | *** bruce.el |
236 | ||
82f289a4 | 237 | *** mailpost.el |
d57de7fe CY |
238 | |
239 | *** mouse-sel.el | |
240 | ||
3c74813a GM |
241 | *** patcomp.el |

244 | * New Modes and Packages in Emacs 24.2 | |
245 | \f | |
246 | * Incompatible Lisp Changes in Emacs 24.2 | |
b4d3bc10 CY |
247 | |
248 | +++ | |
249 | ** Docstrings starting with `*' no longer indicate user options. | |
250 | Only variables defined using `defcustom' are considered user options. | |
251 | The function `user-variable-p' is now an obsolete alias for | |
252 | `custom-variable-p'. | |
253 | ||
eeddc531 CY |
254 | ** `face-spec-set' no longer sets frame-specific attributes when the |
255 | third argument is a frame (that usage was obsolete since Emacs 22.2). | |
256 | ||
a59d531e MA |
257 | +++ |
258 | ** The arguments of `dbus-register-signal' are no longer just strings, | |
259 | but keywords or keyword-string pairs. The old argument list will | |
260 | still be supported for Emacs 24.x. | |
261 | ||
78f3273a CY |
262 | ** The following obsolete variables and varaliases have been removed: |
263 | ||
264 | *** `facemenu-unlisted-faces' | |
265 | *** `rmail-decode-mime-charset' | |
266 | ||

268 | * Lisp changes in Emacs 24.2 | |
ef24141c | 269 | |
f95e9344 SM |
270 | ** New function `set-temporary-overlay-map'. |
271 | ||
272 | ** New macros `setq-local' and `defvar-local'. | |
273 | ||
71873e2b | 274 | ** New error type and new function `user-error'. Doesn't trigger the debugger. |
f95e9344 | 275 | |
ef24141c SM |
276 | ** Completion |
277 | ||
278 | *** New function `completion-table-with-quoting' to handle completion | |
279 | in the presence of quoting, such as file completion in shell buffers. | |
280 | ||
281 | *** New function `completion-table-subvert' to use an existing completion | |
282 | table, but with a different prefix. | |
ab0fa4e4 PE |
283 | |
284 | ** Time | |
285 | ||
286 | *** `current-time-string' no longer requires that its argument's year | |
287 | must be in the range 1000..9999. It now works with any year supported | |
288 | by the underlying C implementation. | |
8a61ee22 SM |
289 | |
290 | ** `automount-dir-prefix' is obsolete. | |

292 | * Changes in Emacs 24.2 on non-free operating systems |
293 | ||
294 | ** New configure.bat options on MS-Windows: | |
295 | ||
296 | *** --without-libxml2 omits support for libxml2, even if its presence | |
297 | is detected. | |
298 | ||

eb199145 | 300 | * Installation Changes in Emacs 24.1 |
09e18d03 | 301 | |
31fd3586 GM |
302 | ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
303 | to configure. Note that other libraries used by Emacs, RSVG and GConf, | |
304 | also depend on Gtk+. You can disable them with --without-rsvg and | |
305 | --without-gconf. | |
338648ad | 306 | |
31fd3586 GM |
307 | ** Emacs can be compiled with GnuTLS support. |
308 | This happens by default if a suitably recent version of the library is | |
309 | found at build time. To prevent this, use the configure option | |
310 | `--without-gnutls'. See below for GnuTLS features. | |
338648ad | 311 | |
31fd3586 GM |
312 | ** Emacs can be compiled with SELinux support. |
313 | This happens by default if a suitably recent version of the library is | |
314 | found at build time. To prevent this, use the configure option | |
315 | `--without-selinux'. See below for SELinux features. | |
aded53ff | 316 | |
31fd3586 GM |
317 | ** Emacs can be compiled with ImageMagick support. |
318 | This happens by default if a suitably recent version of the library is | |
319 | found at build time. To prevent this, use the configure option | |
320 | `--without-imagemagick'. See below for ImageMagick features. | |
c1f10868 | 321 | This feature is not available for the Nextstep or MS ports. |
d9170db5 | 322 | |
043efd56 GM |
323 | ** Emacs can be compiled with libxml2 support. |
324 | This happens by default if a suitably recent version of the library is | |
325 | found at build time. To prevent this, use the configure option | |
326 | `--without-xml2'. See below for libxml2 features. | |
327 | ||
7d301ae6 CY |
328 | ** By default, the installed Info and man pages are compressed. |
329 | You can disable this by configuring --without-compress-info. | |
330 | ||
7d301ae6 | 331 | ** New configure option --with-wide-int. |
81eafe29 | 332 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. |
0a768890 PE |
333 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB |
334 | to about 2 GiB. | |
81eafe29 | 335 | |
7d301ae6 | 336 | ** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost. |
31fd3586 GM |
337 | These provide no new functionality, they just remove the need to edit |
338 | lib-src/Makefile by hand in order to use the associated features. | |
339 | ||
7d301ae6 | 340 | ** New configure option --enable-use-lisp-union-type. |
31fd3586 GM |
341 | This is only useful for Emacs developers to debug certain types of bugs. |
342 | This is not a new feature; only the configure flag is new. | |
041d709f CY |
343 | |
344 | ** The standalone programs digest-doc and sorted-doc are removed. | |
345 | Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'. | |
346 | ||
041d709f CY |
347 | ** The standalone program `fakemail' is removed. |
348 | If you need it, feedmail.el provides a superset of the functionality. | |

eb199145 | 351 | * Startup Changes in Emacs 24.1 |
4a263588 | 352 | |
198a7a97 | 353 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte |
adbf62ff GM |
354 | command line arguments, and the EMACS_UNIBYTE environment variable, no |
355 | longer have any effect. (They were declared obsolete in Emacs 23.) | |
198a7a97 | 356 | |
66b7b0fe | 357 | ** New command line option `--no-site-lisp' removes site-lisp directories |
1b5e5b0c GM |
358 | from load-path. -Q now implies this. This option does not affect the |
359 | EMACSLOADPATH environment variable (and hence has no effect for | |
c8d59ba3 | 360 | Nextstep builds). |

a2a25d24 | 365 | ** Completion |
fdeb32ec | 366 | |
dfdb4cad CY |
367 | *** Many packages now use the `completion-at-point' command, |
368 | rather than implementing separate completion commands. | |
369 | ||
de0bde62 | 370 | *** `completion-at-point' now handles tags and semantic completion. |
dfdb4cad | 371 | |
a2a25d24 SM |
372 | *** Completion in a non-minibuffer now tries to detect the end of completion |
373 | and pops down the *Completions* buffer accordingly. | |
dfdb4cad CY |
374 | |
375 | *** New option `completion-cycle-threshold' allows completion cycling. | |
376 | ||
377 | *** New option `completion-category-overrides' for overriding the | |
2c719188 | 378 | default completion style in certain circumstances. |
dfdb4cad | 379 | |
a2a25d24 | 380 | *** New completion style `substring'. |
dfdb4cad CY |
381 | |
382 | *** Completion of buffer names uses `substring' completion by default. | |
383 | ||
384 | *** The option `widget-complete-field' has been removed. | |

6870aaef | 386 | ** Mail changes |
dfdb4cad | 387 | |
7d301ae6 CY |
388 | *** The first time you try sending mail, Emacs asks for a mail method. |
389 | This is implemented by a new default for `send-mail-function', which | |
390 | is `sendmail-query-once'. This offers to use the smtpmail package, or | |
391 | to use the old defaults relying on external mail facilities | |
392 | (`sendmail-send-it' on GNU/Linux and other Unix-like systems, and | |
393 | `mailclient-send-it' on Windows). | |
dfdb4cad | 394 | |
7d301ae6 CY |
395 | *** Typing C-c m in the buffer made by M-x report-emacs-bug transfers |
396 | the report to your desktop's preferred mail client, if there is one. | |
397 | This uses either the "xdg-email" utility, or Mac OS's "open" command. | |
dfdb4cad | 398 | |
7d301ae6 CY |
399 | *** See Changes in Specialized Modes and Packages for SMTPmail changes |
400 | and Mail mode changes | |

041d709f | 402 | ** Emacs server and client changes |
dfdb4cad | 403 | |
7d301ae6 | 404 | *** New option `server-port' specifies the port for TCP Emacs servers. |
dfdb4cad | 405 | |
041d709f | 406 | *** New emacsclient argument -q/--quiet suppresses some status messages. |
dfdb4cad | 407 | |
7d301ae6 CY |
408 | *** New emacsclient argument --frame-parameters specifies the frame |
409 | parameters of any newly-created graphical frame. | |
dfdb4cad CY |
410 | |
411 | *** If emacsclient shuts down due to Emacs signaling an error, | |
412 | its exit status is 1. | |
413 | ||
041d709f CY |
414 | *** New emacsclient argument --parent-id ID. |
415 | This opens a client frame in parent X window ID, via XEmbed, similar | |
416 | to the --parent-id argument to Emacs. | |
417 | ||
d0ce9f8c MB |
418 | ** Internationalization changes |
419 | ||
d0ce9f8c | 420 | *** Emacs now supports display and editing of bidirectional text. |
7d301ae6 CY |
421 | Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are |
422 | displayed in the correct visual order as expected by users of those | |
dfdb4cad CY |
423 | scripts. The display reordering is a "full bidirectionality" class |
424 | implementation of the Unicode Bidirectional Algorithm (UBA). Buffers | |
425 | with no RTL text should look exactly the same as before. | |
f4b6ba46 | 426 | |
041d709f | 427 | **** New buffer-local variable `bidi-display-reordering'. |
7d301ae6 | 428 | To disable display reordering in a buffer, change this to nil. |
d20e1419 | 429 | |
041d709f CY |
430 | **** New buffer-local variable `bidi-paragraph-direction'. |
431 | If nil (the default), Emacs determines the base direction of each | |
dfdb4cad CY |
432 | paragraph from its text, as specified by the UBA. Setting the value |
433 | to `right-to-left' or `left-to-right' forces a base direction on each | |
434 | paragraph. | |
f4b6ba46 | 435 | |
7d301ae6 CY |
436 | Paragraphs with right-to-left base direction are displayed starting at |
437 | the right window edge. | |
f1816485 | 438 | |
dfdb4cad CY |
439 | *** Enhanced support for characters with no glyphs in available fonts, |
440 | or, on text terminals, characters that cannot be encoded by the | |
441 | terminal coding system. The new option `glyphless-char-display-control' | |
442 | specifies how to display them: as a hexadecimal code in a box, a thin | |
443 | 1-pixel space, an empty box, etc. | |
d0ce9f8c | 444 | |
7d301ae6 | 445 | *** New input methods: farsi, farsi-translit, bulgarian-alt-phonetic. |
041d709f | 446 | |
939db9ac CY |
447 | *** `nobreak-char-display' now also highlights Unicode hyphen chars |
448 | (U+2010 and U+2011). | |
449 | ||
7d301ae6 | 450 | *** New Hebrew translation of the Emacs Tutorial. |
31fd3586 GM |
451 | Type `C-u C-h t' to choose it in case your language setup doesn't |
452 | automatically select it. | |
453 | ||
7d301ae6 CY |
454 | ** An Emacs Lisp package manager is now included. |
455 | This is a convenient way to download and install additional packages, | |
456 | from a package repository at http://elpa.gnu.org. | |
dfdb4cad | 457 | |
7d301ae6 CY |
458 | *** M-x list-packages shows a list of packages, which can be |
459 | selected for installation. | |
dfdb4cad | 460 | |
7d301ae6 | 461 | *** New command `describe-package', bound to `C-h P'. |
dfdb4cad | 462 | |
7d301ae6 CY |
463 | *** By default, all installed packages are loaded automatically when |
464 | Emacs starts up. To disable this, set `package-enable-at-startup' to | |
465 | nil. To specify the packages to load, customize `package-load-list'. | |
16a91140 | 466 | |
dfdb4cad CY |
467 | ** Custom theme changes |
468 | ||
7d301ae6 CY |
469 | *** New command `M-x customize-themes', which provides a convenient |
470 | interface for enabling and disabling Custom themes. | |
dfdb4cad | 471 | |
7d301ae6 | 472 | *** New option `custom-theme-load-path' is the load path for themes. |
dfdb4cad CY |
473 | Emacs no longer looks for Custom themes in `load-path'. The default |
474 | value of `custom-theme-load-path' says to look for themes in | |
475 | `custom-theme-directory', followed by a subdirectory of | |
476 | `data-directory' named "themes/", which contains a small selection of | |
477 | built-in Custom themes. | |
478 | ||
7d301ae6 CY |
479 | *** New option `custom-safe-themes' records known-safe theme files. |
480 | If a theme is not in this list, Emacs queries before loading it, and | |
481 | offers to save the theme to `custom-safe-themes' automatically. By | |
482 | default, all themes included in Emacs are treated as safe. | |
b7d65a5f | 483 | |
7d301ae6 | 484 | ** Improved GTK integration |
dfdb4cad | 485 | |
7d301ae6 | 486 | *** GTK scroll-bars are now placed on the right by default. |
dfdb4cad CY |
487 | The function `set-scroll-bar-mode' can change this. |
488 | ||
7d301ae6 | 489 | *** GTK tool bars can have just text, just images or images and text. |
dfdb4cad CY |
490 | Customize `tool-bar-style' to choose the style. On a Gnome desktop, |
491 | the default is taken from desktop settings. | |
492 | ||
493 | *** GTK tool bars can be placed on any edge of the frame. | |
7d301ae6 CY |
494 | The frame-parameter tool-bar-position controls this. It takes the |
495 | values top, left, right or bottom. The Options => Show/Hide menu has | |
496 | entries for this. | |
dfdb4cad | 497 | |
7d301ae6 CY |
498 | *** The default colors for selected text (the `region' face) are taken |
499 | from the GTK theme when Emacs is built with GTK. | |
dfdb4cad | 500 | |
7d301ae6 CY |
501 | *** Emacs uses GTK tooltips by default if built with GTK. |
502 | You can disable this by changing `x-gtk-use-system-tooltips' to nil. | |
a5bee597 | 503 | |
dfdb4cad CY |
504 | ** Graphical interface changes |
505 | ||
506 | *** On graphical displays, the mode-line no longer ends in dashes. | |
507 | Also, the first dash (which does not indicate anything) is just | |
508 | displayed as a space. | |
509 | ||
510 | *** `menu-bar-select-buffer-function' lets you choose another operation | |
511 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. | |
512 | ||
513 | *** Lucid menus and dialogs can display antialiased fonts if Emacs is | |
514 | built with Xft. These fonts can be set via X resources, for example: | |
515 | Emacs.pane.menubar.font: Courier-12 | |
516 | ||
7d301ae6 | 517 | ** Exiting changes |
dfdb4cad | 518 | |
7d301ae6 | 519 | *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP, |
dfdb4cad CY |
520 | or if it receives a SIGINT signal in batch mode. |
521 | ||
7d301ae6 CY |
522 | *** `kill-emacs-hook' is now also run in batch mode. |
523 | Third-party code which adds to `kill-emacs-hook' should check if they | |
524 | do the right thing in batch mode. | |
9c524fcb | 525 | |
041d709f | 526 | ** Scrolling changes |
dfdb4cad | 527 | |
041d709f | 528 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' |
0a19a6f8 | 529 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
7d301ae6 | 530 | of buffer at first key-press (instead they move to top/bottom of buffer) |
550f41cd | 531 | when `scroll-error-top-bottom' is non-nil. |
dfdb4cad CY |
532 | |
533 | *** New option `scroll-error-top-bottom' (see above). | |
534 | ||
041d709f | 535 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' |
5a97d2da | 536 | scroll a line instead of full screen. |
dfdb4cad | 537 | |
041d709f | 538 | *** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 539 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
dfdb4cad | 540 | |
041d709f | 541 | *** If you customize `scroll-conservatively' to a value greater than 100, |
d0f69533 EZ |
542 | Emacs will never recenter point in the window when it scrolls due to |
543 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | |
544 | Previously, you needed to use `most-positive-fixnum' as the value of | |
545 | `scroll-conservatively' to achieve the same effect. | |
dfdb4cad | 546 | |
7d301ae6 | 547 | *** "Aggressive" scrolling now honors the scroll margins. |
d0f69533 EZ |
548 | If you customize `scroll-up-aggressively' or |
549 | `scroll-down-aggressively' and move point off the window, Emacs now | |
550 | scrolls the window so as to avoid positioning point inside the scroll | |
551 | margin. | |
552 | ||
7d301ae6 CY |
553 | ** Basic SELinux support has been added. |
554 | This requires Emacs to be linked with libselinux at build time. | |
f1a5d776 | 555 | |
dfdb4cad CY |
556 | *** Emacs preserves the SELinux file context when backing up. |
557 | Also, the function `copy-file' has an extra optional argument for | |
558 | preserving SELinux context, and the return value of `backup-buffer' | |
559 | now includes the SELinux context. | |
f0bf7c8e | 560 | |
dfdb4cad | 561 | *** New functions `file-selinux-context' and `set-file-selinux-context' |
7d301ae6 | 562 | get and set the SELinux context of a file. |
44198b6e | 563 | |
7d301ae6 | 564 | ** Trash changes |
dfdb4cad | 565 | |
7d301ae6 CY |
566 | *** `delete-by-moving-to-trash' now only affects commands that specify |
567 | trashing. This avoids inadvertently trashing temporary files. | |
dfdb4cad | 568 | |
7d301ae6 CY |
569 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
570 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
278f6845 | 571 | |
041d709f | 572 | ** File- and directory-local variable changes |
dfdb4cad | 573 | |
041d709f CY |
574 | *** You can stop directory local vars from applying to subdirectories. |
575 | Add an element (subdirs . nil) to the alist portion of any variables | |
576 | settings to indicate that the section should not apply to | |
577 | subdirectories. | |
dfdb4cad | 578 | |
041d709f CY |
579 | *** Directory local variables can apply to some file-less buffers. |
580 | Affected modes include dired, vc-dir, and log-edit. For example, | |
581 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will | |
582 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call | |
583 | `hack-dir-local-variables-non-file-buffer' to support this. | |
dfdb4cad | 584 | |
041d709f CY |
585 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. |
586 | Instead, use "eval: (minor-mode 1)". | |
c136e5cd | 587 | |
7b447e9b GM |
588 | *** The variable `inhibit-first-line-modes-regexps' has been renamed |
589 | to `inhibit-local-variables-regexps'. As the name suggests, it now | |
dfdb4cad CY |
590 | applies to ALL file local variables, not just -*- lines. The |
591 | associated `inhibit-first-line-modes-suffixes' has been renamed in the | |
592 | corresponding way. | |
5d907d6c | 593 | |
0a2132ba CY |
594 | ** Window changes |
595 | ||
91b65361 CY |
596 | *** The `quit-window' command now restores the last buffer displayed |
597 | in the quitted window. | |
598 | ||
0a2132ba CY |
599 | *** Resizing an Emacs frame now preserves proportional window sizes, |
600 | modulo restrictions like window minimum sizes and fixed-size windows. | |
601 | ||
602 | *** The behavior of `display-buffer' is now customizable in detail. | |
dfdb4cad | 603 | |
0a2132ba CY |
604 | **** New option `display-buffer-base-action' specifies a list of |
605 | user-determined display "actions" (functions and optional arguments | |
606 | for choosing the displaying window). | |
607 | ||
608 | This takes precedence over the default display action, which is | |
609 | specified by `display-buffer-fallback-action'. | |
610 | ||
611 | **** New option `display-buffer-alist' maps buffer name regexps to | |
612 | display actions, taking precedence over `display-buffer-base-action'. | |
613 | ||
a0c2d0ae MR |
614 | *** New option `window-combination-limit'. |
615 | The new option `window-combination-limit' allows to return the space | |
616 | obtained for resizing or creating a window more reliably to the window | |
617 | from which such space was obtained. | |
0a2132ba | 618 | |
a0c2d0ae MR |
619 | *** New option `window-combination-resize'. |
620 | The new option `window-combination-resize' allows to split a window that | |
621 | otherwise cannot be split because it's too small by stealing space from | |
622 | other windows in the same combination. Subsequent resizing or deletion | |
623 | of the window will resize all windows in the same combination as well. | |
0a2132ba | 624 | |
91b65361 CY |
625 | *** New option `frame-auto-hide-function' lets you choose between |
626 | iconifying or deleting a frame when burying a buffer in a dedicated | |
627 | frame, or quitting a window showing a buffer in a frame of its own. | |
628 | ||
0a2132ba | 629 | *** New commands `maximize-window' and `minimize-window'. |
53964682 | 630 | These maximize and minimize the size of a window within its frame. |
0a2132ba | 631 | |
0a2132ba CY |
632 | *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'. |
633 | These functions allow to navigate through the live buffers that have | |
634 | been shown in a specific window. | |
635 | ||
7d301ae6 | 636 | ** Minibuffer changes |
dfdb4cad | 637 | |
7d301ae6 | 638 | *** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. |
104dc9c6 GM |
639 | This is handy for minibuffer-only frames, and is also used for the feature |
640 | where mouse-1 pops up *Messages*"', which can now easily be changed. | |
041d709f | 641 | |
7d301ae6 | 642 | *** Minibuffers set `truncate-lines' to nil. |
f66eca26 | 643 | If you want to change the value to something else, you could use |
7d301ae6 CY |
644 | for example `minibuffer-setup-hook'. |
645 | ||
7d301ae6 CY |
646 | ** `auto-mode-case-fold' is now enabled by default. |
647 | ||
7d301ae6 | 648 | ** `backup-by-copying-when-mismatch' now defaults to t. |
f66eca26 | 649 | |
dfdb4cad CY |
650 | ** New basic faces `error', `warning', `success'. |
651 | These are used to highlight text indicating failure, caution or | |
652 | successful operation. | |
653 | ||
654 | ** New option `list-colors-sort' defines the color sort order | |
655 | for `list-colors-display'. | |
656 | ||
657 | ** The variable `focus-follows-mouse' now always defaults to nil. | |

b350bdf2 | 661 | |
892777ba | 662 | ** Search changes |
dfdb4cad CY |
663 | |
664 | *** C-y in Isearch is now bound to `isearch-yank-kill', instead of | |
665 | `isearch-yank-line'. | |
666 | ||
667 | *** M-y in Isearch is now bound to `isearch-yank-pop', instead of | |
668 | `isearch-yank-kill'. | |
669 | ||
670 | *** M-s C-e in Isearch is now bound to `isearch-yank-line'. | |
671 | ||
b2b0776e | 672 | ** New commands `count-words-region' and `count-words'. |
dfdb4cad | 673 | |
10607bea CY |
674 | *** M-= is bound to `count-words-region', not `count-lines-region'. |
675 | The `count-words-region' command, when called interactively, reports | |
676 | the number of lines, words, and characters in the region. It is a | |
677 | superset of the old `count-lines-region', which is now an obsolete | |
678 | alias for it. | |
ea4f7750 | 679 | |
ec9da840 | 680 | ** The command `just-one-space' (M-SPC), if given a negative argument, |
1c708c1a CY |
681 | also deletes newlines around point. |
682 | ||
b9229673 | 683 | ** Deletion changes |
dfdb4cad | 684 | |
b9229673 | 685 | *** New option `delete-active-region'. |
ddb54206 | 686 | If non-nil, [delete] and DEL delete the region if it is active and no |
dfdb4cad | 687 | prefix argument is given. If set to `kill', those commands kill |
ddb54206 | 688 | instead. |
dfdb4cad | 689 | |
59ee0542 | 690 | *** New command `delete-forward-char', bound to [delete]. |
42d9cffa CY |
691 | This is meant for interactive use, and obeys `delete-active-region'. |
692 | The command `delete-char' does not obey `delete-active-region'. | |
dfdb4cad | 693 | |
b9229673 CY |
694 | *** `delete-backward-char' is now a Lisp function. |
695 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
7d301ae6 CY |
696 | However, the byte compiler now warns if it is called from Lisp; Lisp |
697 | callers should use delete-char with a negative argument instead. | |
dfdb4cad | 698 | |
b9229673 CY |
699 | *** The option `mouse-region-delete-keys' has been deleted. |
700 | ||
f9d71b42 CY |
701 | ** Selection changes. |
702 | ||
7d301ae6 CY |
703 | The default handling of clipboard and primary selections has been |
704 | changed to conform with modern X applications. In short, most | |
705 | commands for killing and yanking text now use the clipboard, while | |
706 | mouse commands use the primary selection. | |
b1ab31ae CY |
707 | |
708 | In the following, we provide a list of these changes, followed by a | |
709 | list of steps to get the old behavior back if you prefer that. | |
710 | ||
b1ab31ae CY |
711 | *** `select-active-regions' now defaults to t. |
712 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
963578d3 | 713 | the kill ring. The selected text is put in the primary selection, if |
b1ab31ae CY |
714 | the system possesses a separate primary selection facility (e.g. X). |
715 | ||
716 | **** `select-active-regions' also accepts a new value, `only'. | |
717 | This means to only set the primary selection for temporarily active | |
718 | regions (usually made by mouse-dragging or shift-selection); | |
719 | "ordinary" active regions, such as those made with C-SPC followed by | |
720 | point motion, do not alter the primary selection. | |
721 | ||
963578d3 CY |
722 | **** `mouse-drag-copy-region' now defaults to nil. |
723 | ||
b1ab31ae CY |
724 | *** mouse-2 is now bound to `mouse-yank-primary'. |
725 | This pastes from the primary selection, ignoring the kill-ring. | |
726 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
dfdb4cad | 727 | |
b1ab31ae | 728 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
dfdb4cad | 729 | |
b1ab31ae CY |
730 | *** `x-select-enable-primary' now defaults to nil. |
731 | Thus, commands that kill text or copy it to the kill-ring (such as | |
732 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
733 | ||
734 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now | |
dfdb4cad | 735 | exactly equivalent to M-w, C-w, and C-y respectively. |
b1ab31ae CY |
736 | |
737 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already | |
738 | non-nil by default, as Windows does not support the primary selection | |
739 | between applications. | |
740 | ||
741 | *** To return to the previous behavior, do the following: | |
dfdb4cad | 742 | |
104c2fe9 | 743 | **** Change `select-active-regions' to nil. |
b1ab31ae CY |
744 | **** Change `mouse-drag-copy-region' to t. |
745 | **** Change `x-select-enable-primary' to t (on X only). | |
746 | **** Change `x-select-enable-clipboard' to nil. | |
747 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 748 | |
084e6df3 | 749 | *** Support for X cut buffers has been removed. |
dfdb4cad | 750 | |
3fd50d5c CY |
751 | *** X clipboard managers are now supported. |
752 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. | |
4b80f674 | 753 | |
dfdb4cad CY |
754 | ** New command `C-x r N' (`rectangle-number-lines') numbers the lines |
755 | in the current rectangle. With a prefix argument, this prompts for a | |
756 | number to count from and for a format string. | |
99f053cf | 757 | |
7d301ae6 | 758 | ** `redisplay-dont-pause' now defaults to t. |
6bf7006f EZ |
759 | This makes Emacs feel more responsive to editing commands that arrive |
760 | at high rate, e.g. if you lean on some key, because stopping redisplay | |
761 | in the middle (when this variable is nil) forces more expensive | |
762 | updates later on, and Emacs appears to be unable to keep up. | |
763 | ||
e70b5064 CY |
764 | ** The behavior of <TAB> for active regions in Text mode has changed. |
765 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | |
766 | when the region is active causes Emacs to indent all the lines in the | |
767 | region, aligning them with the line previous to the first line in the | |
768 | region (or with the left margin if there is no previous line). | |
769 | ||

770 | ** When `occur' is called with a prefix argument, matching strings are |
771 | collected into the `*Occur*' buffer without line numbers. If there | |
772 | are parenthesized subexpressions in the specified regexp, `occur' | |
773 | reads replacement text that may contain \\& and \\N whose convention | |
774 | follows `replace-match'. | |

eb199145 | 777 | * Changes in Specialized Modes and Packages in Emacs 24.1 |
efeb796b | 778 | |
041d709f | 779 | ** Archive Mode has basic support for browsing and updating 7z archives. |
d76674bb | 780 | |
b7c3692a | 781 | ** BibTeX mode |
dfdb4cad | 782 | |
2de69e00 | 783 | *** BibTeX mode now supports biblatex. |
7d301ae6 CY |
784 | Use the variable `bibtex-dialect' to select different BibTeX dialects. |
785 | `bibtex-entry-field-alist' is now an obsolete alias for | |
786 | `bibtex-BibTeX-entry-alist'. | |
787 | ||
dfdb4cad CY |
788 | *** New command `bibtex-search-entries', bound to C-c C-a. |
789 | ||
b7c3692a | 790 | *** New `bibtex-entry-format' option `sort-fields', disabled by default. |
dfdb4cad | 791 | |
022fe7ce RW |
792 | *** New variable `bibtex-search-entry-globally'. |
793 | ||
7d301ae6 | 794 | ** Browse-url |
dfdb4cad | 795 | |
7d301ae6 | 796 | *** New option `browse-url-mailto-function' specifies how to handle "mailto:"s. |
dfdb4cad | 797 | |
7d301ae6 CY |
798 | *** The default browser used by the package is now the "xdg-open" program, |
799 | on platforms that support it. This calls your desktop's preferred browser. | |
800 | ||
cf16af42 GM |
801 | ** Calendar, Diary, and Appt |
802 | ||
7d301ae6 | 803 | *** Diary entries can contain non-printing "comments". |
548d0a63 GM |
804 | See the variable `diary-comment-start'. |
805 | ||
5006e634 GM |
806 | *** Appointments can specify their individual warning times. |
807 | See the variable `appt-warning-time-regexp'. | |
808 | ||
0a2bb1a9 GM |
809 | *** The function specified by `appt-disp-window-function' may be passed |
810 | lists of arguments if multiple appointments are due at similar times. | |
811 | If you are using a custom function for this, you should update it. | |
812 | ||
7454f200 GM |
813 | *** New function `diary-hebrew-birthday'. |
814 | ||
e565dd37 GM |
815 | *** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array' |
816 | may no longer be nil, but must all be strings. | |
817 | ||
7d301ae6 CY |
818 | *** The obsolete (since Emacs 22.1) method of enabling the appt |
819 | package by adding `appt-make-list' to `diary-hook' has been removed. | |
820 | Use `appt-activate' instead. | |
cf16af42 | 821 | |
cf16af42 GM |
822 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: |
823 | appt-issue-message (use the function appt-activate) | |
824 | appt-visible/appt-msg-window (use the variable appt-display-format) | |
825 | ||
cf16af42 GM |
826 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: |
827 | view-diary-entries, list-diary-entries, show-all-diary-entries | |
828 | ||
551b046f | 829 | ** CC Mode |
dfdb4cad | 830 | |
551b046f | 831 | *** New feature to "guess" the style in an existing buffer. |
7d301ae6 | 832 | The main entry point is M-x c-guess. |
041d709f | 833 | |
551b046f AM |
834 | *** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang). |
835 | ||
dfdb4cad | 836 | *** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes. |
551b046f AM |
837 | Thus C-M-a will, by default, go to the beginning of the immediate function, |
838 | not the top level. | |
839 | ||
dfdb4cad | 840 | *** "Macros with semicolons" can be registered for correct indentation. |
551b046f AM |
841 | Where such a macro ends a line (no semicolon) the next statement is no longer |
842 | parsed as a statement continuation. | |
843 | ||
dfdb4cad | 844 | ** Comint and modes derived from it use the standard completion code. |
041d709f CY |
845 | |
846 | ** Compilation mode | |
dfdb4cad | 847 | |
7d301ae6 | 848 | *** Compilation mode can be used without Font Lock mode. |
041d709f CY |
849 | `compilation-parse-errors-function' is now obsolete. |
850 | ||
dfdb4cad | 851 | *** New variable `compilation-filter-start', which is bound while |
7d301ae6 CY |
852 | `compilation-filter-hook' runs. It records the start position of the |
853 | text inserted by `compilation-filter'. | |
041d709f | 854 | |
47a6a35f GM |
855 | *** `compilation-error-screen-columns' and `compilation-first-column' |
856 | are obeyed in the editing buffer. So programming language modes can | |
7d301ae6 CY |
857 | set them, whereas previously only the value in the *Compilation* |
858 | buffer was used. | |
1dce7193 | 859 | |
52834b6b CY |
860 | ** Customize |
861 | ||
862 | *** Customize buffers now contain a search field. | |
863 | The search is performed using `customize-apropos'. | |
7d301ae6 | 864 | To turn off the search field, set `custom-search-field' to nil. |
52834b6b CY |
865 | |
866 | *** Custom options now start out hidden if at their default values. | |
867 | Use the arrow to the left of the option name to toggle visibility. | |
868 | ||
869 | *** custom-buffer-sort-alphabetically now defaults to t. | |
870 | ||
871 | *** The color widget now has a "Choose" button, which allows you to | |
7d301ae6 | 872 | choose a color via `list-colors-display'. |
52834b6b | 873 | |
041d709f CY |
874 | ** D-Bus |
875 | ||
5da3be7f GM |
876 | *** It is now possible to access buses other than the default system |
877 | or session bus. | |
041d709f | 878 | |
7d301ae6 | 879 | *** The `dbus-register-method' and `dbus-register-property' functions |
5da3be7f | 880 | optionally do not register names. |
041d709f | 881 | |
7d301ae6 | 882 | *** The new function `dbus-register-service' registers a known service |
dfdb4cad | 883 | name on a D-Bus without also registering a property or a method. |
041d709f | 884 | |
f5d6548a | 885 | ** Dired-x |
425a25f1 | 886 | |
7d301ae6 CY |
887 | *** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'), |
888 | if called with a prefix argument, read a file name from the minibuffer | |
889 | instead of using the current buffer. | |
f5d6548a | 890 | |
7d301ae6 | 891 | *** The "dired local variables" feature of Dired-x is obsolete. |
817b48a7 | 892 | The standard directory local variables feature replaces it. |
8117868f | 893 | |
041d709f | 894 | ** ERC changes |
7492acc9 | 895 | |
c4077254 GM |
896 | *** New options `erc-autojoin-timing' and `erc-autojoin-delay', |
897 | controlling attempts to autojoin a channel. | |
041d709f CY |
898 | |
899 | *** New variable `erc-coding-system-precedence': If we use `undecided' | |
900 | as the server coding system, this variable will then be consulted. | |
901 | The default is to decode strings that can be decoded as utf-8 as | |
902 | utf-8, and do the normal `undecided' decoding for the rest. | |
7492acc9 | 903 | |
041d709f | 904 | ** Eshell changes |
7492acc9 | 905 | |
05f77e38 GM |
906 | *** The default value of `eshell-directory-name' has changed |
907 | to be an "eshell" directory in `user-emacs-directory'. | |
908 | The old "~/.eshell/" directory is still used if it exists, though. | |
041d709f CY |
909 | |
910 | ** gdb-mi | |
dfdb4cad CY |
911 | |
912 | *** The M-x gdb command now uses the GDB Machine Interface protocol. | |
05f77e38 GM |
913 | It now supports multithread non-stop debugging and simultaneous |
914 | debugging of several threads. | |
7492acc9 | 915 | |
18af70d0 CY |
916 | ** Image mode |
917 | ||
05f77e38 GM |
918 | *** RET (`image-toggle-animation') toggles animation, if applicable. |
919 | Animation plays once, unless the option `image-animate-loop' is non-nil. | |
18af70d0 | 920 | |
041d709f | 921 | ** Info |
723ee192 | 922 | |
7d301ae6 | 923 | *** New command M-x info-display-manual displays a named Info manual. |
2ebc3b94 GM |
924 | If that manual is already visited in some Info buffer, it displays |
925 | that buffer. (This is handy if you have many manuals in many *info* | |
926 | buffers, and don't remember the name of the buffer visiting the manual | |
927 | you want to consult.) Otherwise, it loads and displays the manual. | |
691cf4a0 | 928 | |
24ea72d3 EZ |
929 | *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'. |
930 | This is for compatibility with the stand-alone Info reader program, | |
931 | and also because `Info-edit' is a rarely used command that is disabled | |
932 | by default. | |
933 | ||
7d301ae6 | 934 | ** Mail mode changes (not Message mode) |
dfdb4cad | 935 | |
7d301ae6 | 936 | *** New command M-x mail-add-attachment for adding MIME attachments |
7d301ae6 | 937 | |
dfdb4cad CY |
938 | *** The command M-x mail-attach-file was renamed to M-x mail-insert-file. |
939 | (Its name is misleading, since it has nothing to do with MIME | |
940 | attachments.) The old name is now an obsolete alias to the new name. | |
941 | ||
f2c3a9eb | 942 | ** MH-E has been updated to MH-E version 8.3.1. |
041d709f | 943 | See MH-E-NEWS for details. |
37221432 | 944 | |
041d709f | 945 | ** Modula-2 mode provides auto-indentation. |
37221432 | 946 | |
041d709f | 947 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
3c3d4f5b | 948 | |
5d1ac394 | 949 | ** nXML mode no longer binds C-RET to `nxml-complete'. |
dfdb4cad CY |
950 | Completion is now performed via `completion-at-point', bound to C-M-i |
951 | or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the | |
952 | default), this performs tag completion. | |
5d1ac394 | 953 | |
f2c3a9eb CY |
954 | ** Org mode has been updated to version 7.8.09. |
955 | See ORG-NEWS for details. | |
956 | ||
041d709f | 957 | ** Prolog mode has been completely revamped, with lots of additional |
7d301ae6 CY |
958 | functionality such as more intelligent indentation, electricity, |
959 | support for more variants, including Mercury, and a lot more. | |
041d709f CY |
960 | |
961 | ** Rmail | |
962 | ||
963 | *** The command `rmail-epa-decrypt' decrypts OpenPGP data | |
964 | in the Rmail incoming message. | |
965 | ||
50419064 GM |
966 | *** The variable `rmail-message-filter' no longer has any effect. |
967 | This change was made in Emacs 23.1 but was not advertised at the time. | |
968 | Try using `rmail-show-message-hook' instead. | |
969 | ||
717a1362 | 970 | ** Shell mode |
dfdb4cad CY |
971 | |
972 | *** M-x shell prompts for the shell path name if the default directory | |
973 | is a remote file name and neither the environment variable $ESHELL nor | |
974 | the variable `explicit-shell-file-name' is set. | |
975 | ||
976 | *** TAB is now bound to the standard `completion-at-point' command, | |
977 | which now implements the pcomplete rules for shell command completion. | |
717a1362 | 978 | |
7d301ae6 CY |
979 | ** SMTPmail |
980 | ||
dfdb4cad | 981 | *** SMTPmail now uses encrypted connections (via STARTTLS) by default |
7d301ae6 CY |
982 | if the mail server supports them. This uses either built-in GnuTLS |
983 | support, or the starttls.el library. Customize `smtpmail-stream-type' | |
984 | to change this. | |
985 | ||
7d301ae6 CY |
986 | *** The variable `smtpmail-auth-credentials' has been removed. |
987 | By default, the information is now stored in the file ~/.authinfo. | |
dfdb4cad CY |
988 | This was the default value of smtpmail-auth-credentials. If you had |
989 | customized smtpmail-auth-credentials to a list of user names and | |
990 | passwords, those settings are not used. During your first connection | |
991 | to the smtp server, Emacs will prompt for the user name and password, | |
992 | and offer to save them to ~/.authinfo. Or you can manually copy the | |
993 | credentials to ~/.authinfo. For example, if you had | |
7d301ae6 CY |
994 | |
995 | (setq smtpmail-auth-credentials | |
996 | '(("mail.example.org" 25 "jim" "s!cret"))) | |
997 | ||
998 | then the equivalent line in ~/.authinfo would be | |
999 | ||
1000 | machine mail.example.org port 25 login jim password s!cret | |
1001 | ||
1002 | See the auth-source manual for more information, e.g. on encrypting | |
1003 | the credentials file. | |
1004 | ||
7d301ae6 | 1005 | *** The variable `smtpmail-starttls-credentials' has been removed. |
dfdb4cad | 1006 | If you had that set, you need to put |
7d301ae6 CY |
1007 | |
1008 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert" | |
1009 | ||
1010 | in your ~/.authinfo file instead. | |
1011 | ||
34e8a2da | 1012 | ** SQL mode |
041d709f | 1013 | |
34e8a2da GM |
1014 | *** New options `sql-port', `sql-connection-alist', `sql-send-terminator', |
1015 | and `sql-oracle-scan-on'. | |
041d709f | 1016 | |
dfdb4cad | 1017 | *** New options controlling prompting for login parameters. |
34e8a2da GM |
1018 | Each supported product has a custom variable `sql-*-login-params', |
1019 | which is a list of the parameters to be prompted for before a | |
1020 | connection is established. | |
041d709f CY |
1021 | |
1022 | *** The command `sql-product-interactive' now takes a prefix argument, | |
34e8a2da | 1023 | which causes it to prompt for an SQL product. |
041d709f | 1024 | |
34e8a2da | 1025 | *** Product-specific SQL interactive commands now take prefix arguments. |
041d709f CY |
1026 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), |
1027 | given a prefix argument, prompt for a name for the SQL interactive | |
1028 | buffer. This reduces the need for calling `sql-rename-buffer'. | |
1029 | ||
1030 | *** SQL interactive modes suppress command continuation prompts, and | |
1031 | replace tabs with spaces. The first change impacts multiple line SQL | |
1032 | statements entered with C-j between each line, statements yanked into | |
1033 | the buffer and statements sent with `sql-send-*' functions. The | |
34e8a2da GM |
1034 | second prevents the MySQL and Postgres interpreters from listing |
1035 | object name completions when sent text via `sql-send-*' functions. | |
041d709f CY |
1036 | |
1037 | *** New command `sql-connect' starts a predefined SQLi session, | |
1038 | using the login parameters from `sql-connection-alist'. | |
1039 | ||
1040 | *** New "Save Connection" menu item in SQLi buffers. | |
1041 | This gathers the login params specified for the SQLi session, if it | |
1042 | was not started by a connection, and saves them as a new connection. | |
1043 | ||
34e8a2da GM |
1044 | *** New commands for listing database objects and details: |
1045 | sql-list-all and sql-list-table. | |
041d709f CY |
1046 | |
1047 | *** An API for manipulating SQL product definitions has been added. | |
1048 | ||
1049 | ** TeX modes | |
1050 | ||
1051 | *** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. | |
412b9ee5 | 1052 | |
459bba37 | 1053 | ** Tramp |
dfdb4cad | 1054 | |
7d301ae6 | 1055 | *** New inline access method "ksu" (kerberized su). |
dfdb4cad | 1056 | |
459bba37 | 1057 | *** The following access methods are discontinued: "ssh1_old", |
ea843702 | 1058 | "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish". |
dfdb4cad | 1059 | |
b011fbfe GM |
1060 | *** The user option `remote-file-name-inhibit-cache' controls whether |
1061 | remote file attributes are cached for better performance. | |
dfdb4cad | 1062 | |
58f74fe4 MA |
1063 | *** The option `ange-ftp-binary-file-name-regexp' has changed its |
1064 | default value to "". | |
dfdb4cad | 1065 | |
7d301ae6 CY |
1066 | *** Handlers for `file-selinux-context' and `set-file-selinux-context' |
1067 | for remote machines which support SELinux. | |
58f74fe4 | 1068 | |
dfdb4cad | 1069 | ** New function `url-queue-retrieve', which behaves like url-retrieve, |
a48ec60c GM |
1070 | but with limits (`url-queue-parallel-processes', `url-queue-timeout') on |
1071 | the degree of parallelism. | |
177549d0 | 1072 | |
0c32ce32 CY |
1073 | ** VC and related modes |
1074 | ||
1075 | *** Support for pulling on distributed version control systems. | |
7d301ae6 CY |
1076 | The command C-x v + (`vc-pull') runs a "pull" operation, if it is |
1077 | supported (currently with Bzr, Git, and Mercurial), to update the | |
1078 | current branch and working tree. A prefix argument means to prompt | |
1079 | the user for specifics, e.g. a pull location. | |
0c32ce32 | 1080 | |
dab3703d | 1081 | *** `vc-update' is now an alias for `vc-pull'. |
0c32ce32 CY |
1082 | |
1083 | *** Support for merging on distributed version control systems. | |
7d301ae6 CY |
1084 | The command C-x v m (`vc-merge') now runs a "merge" operation, if it |
1085 | is supported (currently with Bzr, Git, and Mercurial), to merge | |
1086 | changes from another branch into the current one. It prompts for | |
1087 | specifics, e.g. a merge source. | |
0c32ce32 | 1088 | |
2afef60a | 1089 | *** New option `vc-revert-show-diff' controls whether `vc-revert' |
bbe43420 | 1090 | shows a diff while querying the user. It defaults to t. |
2afef60a | 1091 | |
d4eb88c7 CY |
1092 | *** Log entries in some Log View buffers can be toggled to display a |
1093 | longer description by typing RET (log-view-toggle-entry-display). | |
dab3703d GM |
1094 | This is currently supported for Bzr, Git, and Mercurial (to support |
1095 | another backend, define a `log-view-expanded-log-entry-function'). | |
7d301ae6 | 1096 | In the Log View buffers made by C-x v L (`vc-print-root-log'), you can |
d4eb88c7 CY |
1097 | use this to display the full log entry for the revision at point. |
1098 | ||
1c6c854e CS |
1099 | *** New command `vc-ediff' allows visual comparison of two revisions |
1100 | of a file similar to `vc-diff', but using ediff backend. | |
1101 | ||
86c60681 CY |
1102 | *** The option `vc-initial-comment' was removed in Emacs 23.2, but |
1103 | this was not advertised at the time. | |
1104 | ||
86c60681 CY |
1105 | *** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'. |
1106 | Since Emacs 23, it has done the same thing as `toggle-read-only', but | |
80c6d77f GM |
1107 | this was not advertised at the time. |
1108 | ||
041d709f CY |
1109 | ** Obsolete modes |
1110 | ||
23d70505 GM |
1111 | *** abbrevlist.el |
1112 | ||
f8ca9162 | 1113 | *** erc-hecomplete.el (use erc-pcomplete.el instead) |
23d70505 GM |
1114 | |
1115 | *** partial-completion-mode (complete.el) is obsolete. | |
041d709f CY |
1116 | You can get a comparable behavior with: |
1117 | (setq completion-styles '(partial-completion initials)) | |
1118 | (setq completion-pcm-complete-word-inserts-delimiters t) | |
1119 | ||
23d70505 GM |
1120 | *** pc-mode.el is obsolete (CUA mode is much more comprehensive). |
1121 | ||
2c719188 | 1122 | *** pgg is obsolete (use EasyPG instead). |
041d709f CY |
1123 | |
1124 | *** sregex.el is obsolete, since rx.el is a strict superset. | |

1146 | * New Modes and Packages in Emacs 24.1 | |
d445b3f8 | 1147 | |
60e56523 | 1148 | ** Occur Edit mode applies edits made in *Occur* buffers to the |

1151 | ** New global minor mode electric-pair-mode. |
1152 | When enabled, typing an open parenthesis automatically inserts the | |
1153 | matching closing one. | |
1154 | ||
1155 | ** New global minor mode electric-indent-mode. | |
1156 | When enabled, typing certain characters triggers reindentation. | |
cd3308f3 GM |

1164 | ** tabulated-list.el provides a generic major mode for tabulated data, |
1165 | from which other modes can be derived. | |

1167 | ** pcase.el provides the ML-style pattern matching macro `pcase'. |
1168 | ||
7725ebb7 MA |
1169 | ** secrets.el is an implementation of the Secret Service API, an |
1170 | interface to password managers like GNOME Keyring or KDE Wallet. The | |
065f2743 MA |
1171 | Secret Service API requires D-Bus for communication. The command |

1191 | * Incompatible Lisp Changes in Emacs 24.1 | |
6dfcbe31 | 1192 | |
7d301ae6 CY |
1193 | ** Passing a nil argument to a minor mode function call now ENABLES |
1194 | the minor mode unconditionally. This is so that you can write e.g. | |
1195 | ||
dfdb4cad | 1196 | (add-hook 'text-mode-hook 'foo-mode) |
7d301ae6 | 1197 | |
dfdb4cad CY |
1198 | to enable foo-mode in Text mode buffers, removing the need for |
1199 | `turn-on-foo-mode' style functions. This affects all mode commands | |
1200 | defined by `define-minor-mode'. If called interactively, the mode | |
1201 | command still toggles the minor mode. | |
7d301ae6 | 1202 | |
d268b4fe CY |
1203 | ** The return value of `backup-buffer' has changed. |
1204 | It is now a list of three elements, where the second element is a list | |
1205 | describing the original file's SELinux context. If Emacs or the | |
f003f294 | 1206 | system lacks SELinux support, the context list is (nil nil nil nil). |
7d301ae6 | 1207 | See "Basic SELinux support" above, under "Changes in Emacs 24.1". |
d268b4fe | 1208 | |
dfdb4cad CY |
1209 | ** `char-direction-table' and the `char-direction' function were deleted. |
1210 | They were buggy and inferior to the new support of bidirectional | |
1211 | editing introduced in Emacs 24. If you need the bidirectional | |
1212 | properties of a character, use `get-char-code-property' with the last | |
1213 | argument `bidi-class'. | |
fa6996bc | 1214 | |
470d996d TV |
1215 | ** `copy-directory' now copies the source directory as a subdirectory |
1216 | of the target directory, if the latter is an existing directory. The | |
1217 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy | |
1218 | the contents directly into a pre-existing target directory. | |
1219 | ||
9173a8fb CY |
1220 | ** For mouse click input events in the text area, the Y pixel |
1221 | coordinate in the POSITION list now counts from the top of the text | |
1222 | area, excluding any header line. Previously, it counted from the top | |
1223 | of the header line. | |
1224 | ||
7d301ae6 CY |
1225 | ** Support for "old-style" backquotes, obsolete for 10+ years, has |
1226 | been further reduced. Now a backquote not followed by a space is | |
1227 | always treated as a "new-style" backquote. Please remove all | |
1228 | "old-style" backquotes from your code. If your code uses backquotes | |
1229 | as documented in the Elisp manual, and compiles without warning, then | |
1230 | you have nothing to do in this regard. Code not following the | |
1231 | appropriate conventions may fail to compile. | |
50ab02c5 CY |
1232 | |
1233 | The most common cause of trouble seems to be an old-style backquote | |
1234 | followed by a newline. Another cause of trouble is vector notation | |
1235 | for key sequence notation: instead of [(control ,)] and [(control ')], | |
1236 | you should write [(control ?,)] and [(control ?')], which will work in | |
7d301ae6 | 1237 | older Emacsen too. |

520f2425 GM |
1239 | ** The macro `eval-at-startup' was removed in Emacs 23.2, but this |
1240 | was not advertised at the time. The function `custom-initialize-delay' | |
1241 | replaced all known uses. | |
1242 | ||
7d301ae6 CY |
1243 | ** `view-buffer' now treats special mode-class in the same way that |
1244 | `view-file' has since Emacs 22 (i.e. it won't enable View mode if the | |
1245 | major mode is special). | |
fd5c9dfa | 1246 | |
7d301ae6 | 1247 | ** Menu and tool bar changes |
6431f2e6 | 1248 | |
7d301ae6 | 1249 | *** During startup, Emacs no longer adds entries for `menu-bar-lines' |
0a19a6f8 JB |
1250 | and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'. |
1251 | With these alist entries omitted, `make-frame' checks the value of the | |
1252 | variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create | |
1253 | a menu-bar or tool-bar, respectively. If the alist entries are added, | |
1254 | they override the value of `menu-bar-mode'/`tool-bar-mode'. | |
6431f2e6 | 1255 | |
7d301ae6 CY |
1256 | *** The menu bar bindings's caches are not used any more. |
1257 | Use (where-is-internal <def> nil t) instead. | |
1258 | ||
fe0aa820 | 1259 | ** Regions created by mouse dragging are now normal active regions, |
dfdb4cad | 1260 | similar to those created by shift-selection (see Selection changes |
7d301ae6 CY |
1261 | above). In previous Emacs versions, these regions were delineated by |
1262 | `mouse-drag-overlay'; that variable has been removed. | |
d6d8ee7a | 1263 | |
7d301ae6 CY |
1264 | ** The fourth argument of `filter-buffer-substring' has been removed. |
1265 | If you want to remove text properties from the final result, simply | |
1266 | pass the result through substring-no-properties. | |
34c99998 | 1267 | |

9097e8af | 1319 | |
041d709f | 1320 | ** Code can now use lexical scoping by default instead of dynamic scoping. |
dfdb4cad | 1321 | The `lexical-binding' variable enables lexical scoping for local |
48da7392 | 1322 | variables. It is typically set via a file-local variable in the first |
dfdb4cad CY |
1323 | line of the file, in which case it applies to all the code in that |
1324 | file. | |
1325 | ||
041d709f CY |
1326 | *** `eval' takes a new optional argument `lexical' to choose the new lexical |
1327 | binding instead of the old dynamic binding mode. | |
dfdb4cad | 1328 | |
041d709f CY |
1329 | *** Lexically scoped interpreted functions are represented with a new form |
1330 | of function value which looks like (closure ENV ARGS &rest BODY). | |
1331 | ||
1332 | *** New macro `letrec' to define recursive local functions. | |
dfdb4cad CY |
1333 | |
1334 | *** `defvar' and `defconst' now mark the variable as special (dynamic). | |
1335 | So do `defcustom' and other forms that call `defvar' as a subroutine. | |
1336 | ||
041d709f CY |
1337 | *** New function `special-variable-p' to check whether a variable is |
1338 | declared as dynamically bound. | |
1339 | ||
88ed9e87 SM |
1340 | *** The form ((lambda ...) ...) is deprecated. |
1341 | ||
041d709f CY |
1342 | ** An Emacs Lisp testing tool is now included. |
1343 | Emacs Lisp developers can use this tool to write automated tests for | |

1346 | ** Changes for bidirectional display and editing | |
f1816485 | 1347 | |
041d709f | 1348 | *** New function `current-bidi-paragraph-direction'. |
7d301ae6 | 1349 | This returns the base direction of the paragraph at point. |
041d709f | 1350 | |
041d709f | 1351 | *** New function `bidi-string-mark-left-to-right'. |
dfdb4cad CY |
1352 | Given a string containing characters from right-to-left scripts, this |
1353 | function returns another string which can be safely inserted into a | |
1354 | buffer, such that any following text will be always displayed to the | |
7d301ae6 CY |
1355 | right of that string. (This works by appending an invisible Unicode |
1356 | "LEFT-TO-RIGHT MARK" character if the argument string might need it.) | |
041d709f | 1357 | |
7d301ae6 | 1358 | This is useful when the buffer has overall left-to-right paragraph |
dfdb4cad CY |
1359 | direction and you need to insert a string whose contents are not known |
1360 | in advance, without disrupting the layout of the line. | |
041d709f | 1361 | |
bee0fcef | 1362 | ** Window changes |
dfdb4cad | 1363 | |
c4682d18 MR |
1364 | *** Window tree functions are accessible in Elisp. |
1365 | Functions are provided to return the parent, siblings or child windows | |
1366 | of any window including internal windows (windows not associated with a | |
1367 | buffer) in the window tree. | |
dfdb4cad | 1368 | |
24300f5f CY |
1369 | **** New function `window-valid-p' gives non-nil for live and internal |
1370 | windows. | |
dfdb4cad | 1371 | |
24300f5f | 1372 | **** Window manipulation can deal with internal windows. |
c4682d18 MR |
1373 | Many window handling functions like `split-window', `delete-window', or |
1374 | `delete-other-windows' as well as the window resizing functions can now | |
1375 | act on any window including internal ones. | |
dfdb4cad | 1376 | |
c4682d18 MR |
1377 | *** window-total-height/-width vs window-body-height/-width. |
1378 | The function `window-height' has been renamed to `window-total-height' | |
1379 | and `window-width' has been renamed to `window-body-width'. The old | |
1380 | names are provided as aliases. Two new functions `window-total-width' | |
1381 | and `window-body-height' are provided. | |
dfdb4cad | 1382 | |
c4682d18 MR |
1383 | *** Window parameters specific to window handling functions. |
1384 | For each window you can specify a parameter to override the default | |
1385 | behavior of a number of functions like `split-window', `delete-window' | |
ed6235ea MR |
1386 | and `delete-other-windows'. The variable `ignore-window-parameters' |
1387 | allows to ignore processing such parameters. | |
dfdb4cad | 1388 | |
c4682d18 | 1389 | *** New semantics of third argument of `split-window'. |
c4682d18 MR |
1390 | The third argument of `split-window' has been renamed to SIDE and can be |
1391 | set to any of the values 'below, 'right, 'above, or 'left to make the | |
1392 | new window appear on the corresponding side of the window that shall be | |
1393 | split. Any other value of SIDE will cause `split-window' to split the | |
1394 | window into two side-by-side windows as before. | |
dfdb4cad | 1395 | |
c4682d18 | 1396 | *** Window resizing functions. |
487ffd7a | 1397 | A new standard function for resizing windows called `window-resize' has |
c4682d18 MR |
1398 | been introduced. This and all other functions for resizing windows no |
1399 | longer delete any windows when they become too small. | |
dfdb4cad | 1400 | |
b3c0dbfd MR |
1401 | *** Deleting the selected window now selects the most recently selected |
1402 | live window on that frame instead. | |
dfdb4cad | 1403 | |
c4682d18 MR |
1404 | *** `adjust-window-trailing-edge' adjustments. |
1405 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | |
1406 | is able to resize other windows if a window adjacent to the trailing | |
1407 | edge cannot be shrunk any more. This makes its behavior more similar to | |
1408 | that of Emacs 21 without compromising, however, its inability to delete | |
1409 | windows which was introduced in Emacs 22. | |
dfdb4cad | 1410 | |
c4682d18 MR |
1411 | *** Window-local buffer lists. |
1412 | Windows now have local buffer lists. This means that removing a buffer | |
1413 | from display in a window will preferably show the buffer previously | |
1414 | shown in that window with its previous window-start and window-point | |
1415 | positions. This also means that the same buffer may be automatically | |
1416 | shown twice even if it already appears in another window. | |
dfdb4cad | 1417 | |
bee0fcef CY |
1418 | *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW, |
1419 | which if non-nil requires the buffer to be displayed in the currently | |
1420 | selected window, signaling an error otherwise. If nil, another window | |
1421 | can be used, e.g. if the selected one is strongly dedicated. | |
dfdb4cad | 1422 | |
0a2132ba | 1423 | *** `split-window-vertically' and `split-window-horizontally' renamed |
2d197ffb CY |
1424 | to `split-window-below' and `split-window-right' respectively. |
1425 | The old names are kept as aliases. | |
dfdb4cad | 1426 | |
0a2132ba CY |
1427 | *** Display actions |
1428 | ||
1429 | **** The second arg to `display-buffer' and `pop-to-buffer' is now | |
1430 | named ACTION, and takes a display action of the same form as | |
1431 | `display-buffer-base-action' (see Changes, above). A non-nil, | |
1432 | non-list value is treated specially, as the old meaning. | |
1433 | ||
1434 | **** New variable `display-buffer-overriding-action'. | |
1435 | ||
1436 | **** The procedure of `display-buffer' etc. to choose a window is | |
1437 | determined by combining `display-buffer-overriding-action', | |
1438 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', | |
1439 | and `display-buffer-fallback-action'. The second and fourth of these | |
1440 | are user-customizable variables. | |
1441 | ||
1442 | See the docstring of `display-buffer' for details. | |
bee0fcef | 1443 | |
20d2304d CY |
1444 | *** New functions `window-state-get' and `window-state-put'. |
1445 | These functions allow to save and restore the state of an arbitrary | |
1446 | frame or window as an Elisp object. | |
1447 | ||
a2a25d24 | 1448 | ** Completion |
041d709f | 1449 | |
7d301ae6 CY |
1450 | *** New variable `completion-extra-properties' used to specify extra |
1451 | properties of the current completion: | |
a2a25d24 SM |
1452 | - :annotate-function, same as the old completion-annotate-function. |
1453 | - :exit-function, function to call after completion took place. | |
1454 | ||
7d301ae6 CY |
1455 | *** Functions on `completion-at-point-functions' can return any of the |
1456 | properties valid for `completion-extra-properties'. | |
a2a25d24 | 1457 | |
7d301ae6 | 1458 | *** `completion-annotate-function' is obsolete. |
a2a25d24 | 1459 | |
620c53a6 SM |
1460 | *** New `metadata' method for completion tables. The metadata thus returned |
1461 | can specify various details of the data returned by `all-completions': | |
1462 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | |
1463 | used to select a style in completion-category-overrides. | |
1464 | - `annotation-function' to add annotations in *Completions*. | |
1465 | - `display-sort-function' to specify how to sort entries in *Completions*. | |
1466 | - `cycle-sort-function' to specify how to sort entries when cycling. | |

7d301ae6 CY |
1468 | *** `minibuffer-local-filename-must-match-map' is not used any more. |
1469 | Instead, the bindings in `minibuffer-local-filename-completion-map' | |
1470 | are combined with `minibuffer-local-must-match-map'. | |
de09aa52 CY |
1471 | |
1472 | *** New variable `completing-read-function' allows overriding the | |
1473 | behavior of `completing-read'. | |
1474 | ||
f042970d | 1475 | ** `glyphless-char-display' can now distinguish between graphical and |
16a43933 CY |
1476 | text terminal display, via a char-table entry that is a cons cell. |
1477 | ||
7d301ae6 | 1478 | ** `pre-command-hook'/`post-command-hook' are not reset to nil on error. |
f6d62986 SM |
1479 | Instead, the offending function is removed. |
1480 | ||
b1f6fa26 CY |
1481 | ** New hook types |
1482 | ||
1483 | *** New function `run-hook-wrapped' for running an abnormal hook by | |
1484 | passing the hook functions as arguments to a "wrapping" function. | |
e7bc51d0 | 1485 | Like `run-hook-with-args-until-success', it stops at the first |
5385447f | 1486 | non-nil return value. |
e7bc51d0 | 1487 | |
b1f6fa26 CY |
1488 | *** New macro `with-wrapper-hook' for running an abnormal hook as a |
1489 | set of "wrapping" filters, similar to around advice. | |
54521c99 GM |
1490 | (A version of this macro was actually added in Emacs 23.2 but was not |
1491 | advertised at the time.) | |
f6d62986 | 1492 | |
0b19b281 | 1493 | ** Debugger changes |
dfdb4cad | 1494 | |
0b19b281 | 1495 | *** New macro `condition-case-unless-debug' (this was actually added in |
1be3ca5a | 1496 | Emacs 23.1 as condition-case-no-debug, but not advertised) |
dfdb4cad | 1497 | |
0b19b281 | 1498 | *** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised. |
dfdb4cad | 1499 | |
0b19b281 | 1500 | *** Variable `stack-trace-on-error' removed. |
dfdb4cad | 1501 | |
0b19b281 CY |
1502 | *** The debugger can now "continue" from an error, which means it will |
1503 | jump to the error handler as if the debugger had not been invoked | |
1504 | instead of jumping all the way to the top-level. | |
dfdb4cad | 1505 | |
0b19b281 CY |
1506 | *** Set `debug-on-event' to enter the debugger on events like SIGUSR1. |
1507 | This can be useful when `inhibit-quit' is set. | |
d6b1d521 | 1508 | |
953cebf5 | 1509 | ** The new function `server-eval-at' allows evaluation of Lisp forms on |
37576acd | 1510 | named Emacs server instances. |
7deebf1b | 1511 | |
1b9f60cc GM |
1512 | ** `call-process' and `call-process-region' allow a `(:file "file")' spec |
1513 | to redirect STDOUT to a file. | |
7deebf1b | 1514 | |
7d301ae6 CY |
1515 | ** The function `format-time-string' now supports the %N directive, |
1516 | for higher-resolution time stamps. | |
da97a9e6 | 1517 | |
0b19b281 | 1518 | ** New input reading functions |
dfdb4cad | 1519 | |
0b19b281 CY |
1520 | *** New function `read-char-choice' reads a restricted set of |
1521 | characters, discarding any inputs not inside the set. | |
dfdb4cad | 1522 | |
0b19b281 CY |
1523 | *** The command `read-color' now requires a match for a color name |
1524 | or RGB triplet, instead of signaling an error if the user provides | |
1525 | invalid input. | |
dfdb4cad | 1526 | |
0b19b281 | 1527 | **** `facemenu-read-color' is now an alias for `read-color'. |
3ef01959 | 1528 | |
2e288d54 JB |
1529 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
1530 | The variable is now used to load all kind of supported dynamic libraries, | |
1531 | not just image libraries. The previous name is still available as an | |
1532 | obsolete alias. | |
1533 | ||
0b19b281 | 1534 | ** Syntax parsing changes |
dfdb4cad | 1535 | |
0b19b281 | 1536 | *** New variable `syntax-propertize-function'. |
04e2ce72 | 1537 | This replaces `font-lock-syntactic-keywords' which is now obsolete. |
cf38dd42 SM |
1538 | This allows syntax-table properties to be set independently from font-lock: |
1539 | just call syntax-propertize to make sure the text is propertized. | |
1540 | Together with this new variable come a new hook | |
1541 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
1542 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
1543 | as-is; and syntax-propertize-rules which provides a new way to specify | |
1544 | syntactic rules. | |
dfdb4cad | 1545 | |
0b19b281 | 1546 | *** Syntax tables support a new "comment style c" additionally to style b. |
a2e5caf7 | 1547 | |
7d301ae6 | 1548 | ** New hook `post-self-insert-hook', run after `self-insert-command'. |
041d709f | 1549 | |
4e2db1fe | 1550 | ** frame-local variables cannot be let-bound any more. |
041d709f | 1551 | |
15de15c6 | 1552 | ** Major and minor mode changes |
dfdb4cad | 1553 | |
0b19b281 CY |
1554 | *** `set-auto-mode' now respects mode: local variables at the end of files, |
1555 | as well as those in the -*- line. | |
dfdb4cad | 1556 | |
15de15c6 CY |
1557 | *** `prog-mode' is a new major mode from which programming modes |
1558 | should be derived. | |
dfdb4cad | 1559 | |
15de15c6 CY |
1560 | **** `prog-mode-hook' can be used to enable features for programming |
1561 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable | |
1562 | on-the-fly spell checking for comments and strings. | |
dfdb4cad | 1563 | |
15de15c6 CY |
1564 | *** New hook `change-major-mode-after-body-hook', run by |
1565 | `run-mode-hooks' just before any other mode hooks. | |
dfdb4cad | 1566 | |
7a9a2fc6 GM |
1567 | *** Enabled globalized minor modes can be disabled in specific major modes. |
1568 | If the global mode is global-FOO-mode, then run (FOO-mode -1) in the | |
1569 | major mode's hook, where FOO-mode toggles the mode on a per-buffer basis. | |
dfdb4cad | 1570 | |
feb8a83a | 1571 | *** `define-minor-mode' accepts new keywords :variable, :after-hook. |
f44379e7 | 1572 | |
7d301ae6 CY |
1573 | ** File-handling changes |
1574 | ||
7d301ae6 | 1575 | *** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
1576 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
1577 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
1578 | argument is supplied (see Trash changes, above). | |
53967e09 | 1579 | |
7d301ae6 | 1580 | *** New file predicates: `file-equal-p', `file-in-directory-p'. |
ec70a47d | 1581 | |
4039c786 CY |
1582 | ** Tool-bars can display separators. |
1583 | Tool-bar separators are handled like menu separators in menu-bar maps, | |
94975270 | 1584 | i.e. via menu entries of the form `(menu-item "--")'. |
9317e499 | 1585 | |
00fe2df1 JL |
1586 | ** Image API |
1587 | ||
18af70d0 CY |
1588 | *** Animated images support (currently animated gifs only). |
1589 | ||
1590 | **** `image-animated-p' returns non-nil if an image can be animated. | |
1591 | ||
1592 | **** `image-animate' animates a supplied image spec. | |
1593 | ||
1594 | **** `image-animate-timer' returns the timer object for an image that | |
1595 | is being animated. | |
00fe2df1 | 1596 | |
7cb76fe0 GM |
1597 | *** `image-extension-data' has been renamed to `image-metadata'. |
1598 | The old name is an obsolete alias to the new one. | |
1546c559 | 1599 | |
b4ac6e8c GM |
1600 | *** Image mode can view any image type that ImageMagick supports. |
1601 | This requires Emacs to be built with ImageMagick support. | |
7d301ae6 CY |
1602 | |
1603 | **** New function `imagemagick-types', defined if ImageMagick support | |
1604 | is enabled, returns a list of image file extensions that your | |
1605 | ImageMagick installation supports. | |
1606 | ||
1607 | **** New function `imagemagick-register-types' enables ImageMagick | |
1608 | image types in Image mode and in `create-image' and other helper | |
1609 | functions. | |
1610 | ||
1611 | **** New option `imagemagick-types-inhibit' excludes certain | |
1612 | ImageMagick image types from `imagemagick-register-types'. | |
1613 | ||
7d301ae6 CY |
1614 | **** With ImageMagick support, there are extra Image mode commands to |
1615 | resize and rotate images: `image-transform-fit-to-height', | |
1616 | `image-transform-fit-to-width', `image-transform-set-rotation', and | |
1617 | `image-transform-set-scale'. | |
041d709f | 1618 | |
7d301ae6 CY |
1619 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
1620 | passes it to the mail user agent function. This argument specifies an | |
1621 | action for returning to the caller after finishing with the mail. For | |
1622 | example, this is used by Rmail to optionally delete a mail window. | |
b4ac6e8c | 1623 | |
71c17aec | 1624 | ** XML and HTML parsing |
483ab230 CY |
1625 | If Emacs is compiled with libxml2 support, there are two new |
1626 | functions: `libxml-parse-html-region' (which parses "real world" HTML) | |
1627 | and `libxml-parse-xml-region' (which parses XML). Both return an | |
1628 | Emacs Lisp parse tree. | |
4b9832a6 | 1629 | |
7d301ae6 | 1630 | ** Networking and encryption changes |
e2574f2c | 1631 | |
7d301ae6 CY |
1632 | *** `open-network-stream' can now be used to open an encrypted stream. |
1633 | It now accepts an optional `:type' parameter for initiating a TLS | |
1634 | connection, directly or via STARTTLS. To do STARTTLS, additional | |
1635 | parameters (`:end-of-command', `:success', `:capabilities-command') | |
1636 | must also be supplied. | |
1637 | ||
1638 | *** New library gnutls.el. | |
dfdb4cad CY |
1639 | The new function `gnutls-available-p' returns non-nil if Emacs is |
1640 | built with GnuTLS support. The main entry points are | |
1641 | `open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use | |
1642 | these functions through `open-network-stream', because that can | |
7d301ae6 CY |
1643 | upgrade connections through STARTTLS opportunistically or use plain |
1644 | SSL, depending on your needs. For debugging, set `gnutls-log-level' | |
1645 | greater than 0. | |
1646 | ||
7d301ae6 CY |
1647 | *** New primitive `secure-hash' that supports many secure hash algorithms: |
1648 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library | |
1649 | sha1.el has been removed. The `sha1' feature is provided by default. | |
71c17aec | 1650 | |
a6020335 MH |
1651 | ** Isearch |
1652 | ||
1653 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | |
1654 | ||
9326ba26 CY |
1655 | ** Progress reporters can now "spin". |
1656 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
1657 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
1658 | time you call `progress-reporter-update' on that progress reporter, | |
1659 | with a nil or omitted VALUE argument, the reporter message is | |
1660 | displayed with a "spinning bar". | |
1661 | ||
3e214b50 JB |
1662 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is |
1663 | being reverted, even if the buffer has a local `revert-buffer-function'. | |
1664 | ||
001bf877 GM |
1665 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. |
1666 | If delayed-warnings-list is non-nil, the command loop calls | |
7d301ae6 CY |
1667 | `delayed-warnings-hook' after `post-command-hook'. At present, this |
1668 | is only used by Emacs on some platforms to display warnings during | |
1669 | startup, which might otherwise not be noticed. This uses the | |
1670 | functions `display-delayed-warnings' and `collapse-delayed-warnings'. | |
001bf877 | 1671 | |
6420d28b CY |
1672 | ** rx.el has a new `group-n' construct for explicitly numbered groups. |
1673 | ||
dac86404 GM |
1674 | ** New function `make-composed-keymap' that constructs a new keymap |
1675 | from multiple input maps. You can use this to make a keymap that | |
1676 | inherits from multiple maps, eg: | |
1677 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) | |
43dc9f5b | 1678 | |
c8f6ec5c GM |
1679 | ** New function `string-prefix-p'. |
1680 | (This was actually added in Emacs 23.2 but was not advertised at the time.) | |
1681 | ||
27f7ef2f | 1682 | ** New reader macro ## that stands for the empty symbol. |
43dc9f5b AS |
1683 | This means that the empty symbol can now be read back. Also, #: by itself |
1684 | (when not immediately followed by a possible symbol character) stands for | |
1685 | an empty uninterned symbol. | |
041d709f | 1686 | |
fead402d CY |
1687 | ** New math functions `isnan', `copysign', `frexp', `ldexp'. |
1688 | ||
7d301ae6 | 1689 | ** The following functions and variables are obsolete: |
041d709f | 1690 | |
05f77e38 GM |
1691 | *** `tooltip-use-echo-area' is obsolete. |
1692 | Rather than setting this to t, disable Tooltip mode instead. | |
1693 | ||
041d709f CY |
1694 | *** buffer-substring-filters is obsolete. |
1695 | Use `filter-buffer-substring-functions' instead. | |
1696 | ||
1697 | *** `byte-compile-disable-print-circle' is obsolete. | |
1698 | ||
1699 | *** `deferred-action-list' and `deferred-action-function' are obsolete. | |
f160676e GM |
1700 | Use `post-command-hook' instead. |
1701 | ||
67e729a5 CY |
1702 | *** `font-lock-maximum-size' is obsolete. |
1703 | ||
eb199145 GM |
1704 | \f |
1705 | * Changes in Emacs 24.1 on non-free operating systems | |
d53a60a6 | 1706 | |
7a22e700 | 1707 | ** On MS Windows, Emacs warns when using the obsolete init file _emacs, |
a2f0118c GM |
1708 | and also when HOME is set to C:\ by default. |
1709 | ||
7a22e700 | 1710 | ** New configure.bat options |
04779484 | 1711 | |
7a22e700 | 1712 | *** --enable-checking builds Emacs with extra runtime checks. |
e3aef5c6 | 1713 | |
7a22e700 | 1714 | *** --distfiles specifies files to be included in binary distribution. |
e2574f2c | 1715 | |
7a22e700 OK |
1716 | *** --without-gnutls disables automatic GnuTLS detection. |
1717 | ||
a0d363f4 | 1718 | *** --lib for general library linkage, works with the USER_LIBS build variable. |
e2574f2c | 1719 | |
0a19a6f8 | 1720 | ** New make target `dist' to create binary distribution for MS Windows. |
e3aef5c6 | 1721 | |
1f5e1a16 GM |
1722 | ** The Lisp function `w32-default-color-map' is now obsolete. |
1723 | (It is only used internally in the Emacs C code.) | |
5430d399 | 1724 | |
1f5e1a16 GM |
1725 | ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but |
1726 | reappear on mouse-over. (Requires OS X 10.6 or later.) | |
04e2ce72 | 1727 | |
ad7c802c CY |
1728 | ** On Mac OS X, dragging a file into Emacs visits the file, like on |
1729 | other platforms, rather than inserting its contents into the buffer. | |
