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. | |

d71a6517 GM |
26 | --- |
27 | ** The default toolkit has been changed to Gtk+ version 3. | |
28 | If you don't pass --with-x-toolkit to configure or if you pass | |
29 | --with-x-toolkit=gtk or --with-x-toolkit=yes, configure will try to build | |
30 | with Gtk+ version 3, and if that fails, try Gtk+ version 2. | |
31 | You can explicitly require a specific version by passing | |
32 | --with-x-toolkit=gtk2 or --with-x-toolkit=gtk3 to configure. | |
33 | ||
34 | --- | |
8b2e00a3 | 35 | ** New configure option '--without-all' to disable additional features. |
da3d2105 DA |
36 | This disables most of the features that are normally enabled by default. |
37 | ||
d71a6517 | 38 | --- |
da3d2105 DA |
39 | ** New configure option '--enable-link-time-optimization' to utilize |
40 | an appropriate feature provided by GCC since version 4.5.0. | |
41 | ||
d71a6517 | 42 | --- |
b8df54ff PE |
43 | ** New configure option '--enable-gcc-warnings', intended for developers. |
44 | If building with GCC, this enables compile-time checks that warn about | |
45 | possibly-questionable C code. On a recent GNU system there should be | |
46 | no warnings; on older and on non-GNU systems the generated warnings | |
ae6e112d | 47 | may be useful. |
b8df54ff | 48 | |
d71a6517 | 49 | --- |
1a9c6830 | 50 | ** The configure option '--enable-use-lisp-union-type' has been |
d71a6517 GM |
51 | renamed to '--enable-check-lisp-object-type', as the resulting |
52 | Lisp_Object type no longer uses a union to implement the compile time | |
53 | check that this option enables. | |
54 | ||
55 | --- | |
501390c5 PE |
56 | ** The configure option '--disable-maintainer-mode' has been removed, |
57 | as it was confusingly-named and rarely useful. | |
58 | ||
5af9cb6b GM |
59 | --- |
60 | ** You can use `NO_BIN_LINK=t make install' to prevent the installation | |
61 | overwriting "emacs" in the installation bin/ directory with a link | |
62 | to emacs-VERSION. | |
63 | ||
1a9c6830 | 64 | --- |
f14a4380 GM |
65 | ** The configure options `--program-prefix', `--program-suffix', and |
66 | `--program-transform-name' apply to more than just the installed | |
67 | binaries. Now they also affect the man pages, icons, and the | |
68 | etc/emacs.desktop file; but not the info pages, since this would break | |
69 | links between the various manuals. | |
1a9c6830 | 70 | |
a4a18b8b GM |
71 | --- |
72 | ** Emacs uses libtinfo in preference to libncurses, if available. | |
73 | ||
187e9b90 GM |
74 | --- |
75 | ** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and | |
76 | /usr/pkg/lib to the linker search path. You must add them yourself if | |
77 | you want them. | |
78 | ||
276d5f5d GM |
79 | --- |
80 | ** The standalone scripts rcs-checkin and vcdiff have been removed | |
81 | (from the bin and libexec directories, respectively). The former is | |
82 | no longer relevant, the latter is replaced by lisp (in vc-sccs.el). | |

2a1e2476 | 85 | * Startup Changes in Emacs 24.3 |
e5fcdb5e | 86 | |
48de8b12 | 87 | +++ |
e5fcdb5e GM |
88 | ** Emacs no longer searches for `leim-list.el' files beneath the standard |
89 | lisp/ directory. There should not be any there anyway. If you have | |
90 | been adding them there, put them somewhere else, eg site-lisp. | |
91 | ||
4107c81e GM |
92 | --- |
93 | ** The `--no-site-lisp' command line option now works for Nextstep builds. | |

99 | ** Most y-or-n prompts now allow you to scroll the selected window. |
100 | Typing C-v or M-v at a y-or-n prompt scrolls forward or backward | |
101 | respectively, without exiting from the prompt. | |
102 | ||
f938eda9 | 103 | ** Mode line changes |
e109c4a6 | 104 | --- |
f938eda9 CY |
105 | *** New option `mode-line-default-help-echo' specifies the help text |
106 | (shown in a tooltip or in the echo area) for any part of the mode line | |
107 | that does not have its own specialized help text. | |
cd996018 CY |
108 | +++ |
109 | *** You can now click mouse-3 in the coding system indicator to invoke | |
110 | `set-buffer-file-coding-system'. | |

112 | ** Help changes |
113 | ||
48de8b12 | 114 | +++ |
c89926a5 CY |
115 | *** `C-h f' (describe-function) can now perform autoloading. |
116 | When this command is called for an autoloaded function whose docstring | |
117 | contains a key substitution construct, that function's library is | |
118 | automatically loaded, so that the documentation can be shown | |
119 | correctly. To disable this, set `help-enable-auto-load' to nil. | |
120 | ||
48de8b12 | 121 | --- |
c89926a5 CY |
122 | *** `C-h f' now reports previously-autoloaded functions as "autoloaded", |
123 | even after their associated libraries have been loaded (and the | |
124 | autoloads have been redefined as functions). | |
125 | ||
cd996018 CY |
126 | ** Minibuffer changes |
127 | --- | |
128 | *** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the | |
129 | next and previous path separator, respectively. | |
7d806bfe | 130 | +++ |
cd996018 CY |
131 | *** minibuffer-electric-default-mode can rewrite (default ...) to [...]. |
132 | Just set minibuffer-eldef-shorten-default to t before enabling the mode. | |
133 | ||
8f2cb64f | 134 | +++ |
c505aaeb CY |
135 | ** ImageMagick support, if available, is automatically enabled. |
136 | It is no longer necessary to call `imagemagick-register-types' | |
137 | explicitly to install ImageMagick image types; that function is called | |
7d806bfe | 138 | automatically at startup, or when customizing an imagemagick- option. |
73f2b4ab | 139 | +++ |
c505aaeb | 140 | *** Setting `imagemagick-types-inhibit' to t now disables the use of |
87eb79c2 GM |
141 | ImageMagick to view images. You must call imagemagick-register-types |
142 | afterwards if you do not use customize to change this. | |
73f2b4ab | 143 | +++ |
7afbaca4 | 144 | *** The new variable `imagemagick-enabled-types' also affects which |
60b5f187 GM |
145 | ImageMagick types are treated as images. The function |
146 | `imagemagick-filter-types' returns the list of types that will be | |
147 | treated as images. | |
73f2b4ab | 148 | --- |
1b9b4cf4 CY |
149 | *** Images displayed via ImageMagick now support transparency and the |
150 | :background image spec property. | |
c505aaeb | 151 | |
f938eda9 | 152 | ** Server and client changes |
48de8b12 | 153 | +++ |
f938eda9 CY |
154 | *** emacsclient now obeys string values for `initial-buffer-choice', |
155 | if it is told to open a new frame without specifying any file to visit | |
156 | or expression to evaluate. | |
48de8b12 | 157 | --- |
f938eda9 | 158 | *** New option `server-auth-key' specifies a shared server key. |
db80bdc8 | 159 | |
05b621a6 | 160 | +++ |
f938eda9 CY |
161 | ** In the Package Menu, newly-available packages are listed as "new", |
162 | and sorted above the other "available" packages by default. | |
163 | ||
e109c4a6 | 164 | +++ |
f938eda9 CY |
165 | ** `C-x C-q' is now bound to the new minor mode `read-only-mode'. |
166 | This minor mode replaces `toggle-read-only', which is now obsolete. | |
167 | ||
4c1f6a5b | 168 | +++ |
f938eda9 CY |
169 | ** Emacs now generates backtraces on fatal errors. |
170 | On encountering a fatal error, Emacs now outputs a textual description | |
171 | of the fatal signal, and a short backtrace on platforms like glibc | |
172 | that support backtraces. | |
2e2d2a13 | 173 | |
48de8b12 | 174 | --- |
f938eda9 CY |
175 | ** If your Emacs was built from a bzr checkout, the new variable |
176 | `emacs-bzr-version' contains information about the bzr revision used. | |
de6ff46d | 177 | |
dc0f75c8 | 178 | +++ |
f938eda9 CY |
179 | ** New variable `create-lockfiles' specifies usage of lockfiles. |
180 | It defaults to t. Changing it to nil inhibits the creation of lock | |
181 | files (use this with caution). | |
dc0f75c8 | 182 | |
b8a82b69 | 183 | +++ |
03794570 | 184 | ** Using "unibyte: t" in Lisp source files is obsolete. |
57699e37 | 185 | Use "coding: raw-text" instead. |
03794570 | 186 | |
21ffb35a MA |
187 | +++ |
188 | ** Setting `enable-remote-dir-locals' to non-nil allows directory | |
189 | local variables on remote hosts. | |
190 | ||
f938eda9 | 191 | --- |
f85f636a CY |
192 | ** The entry for PCL-CVS has been removed from the Tools menu. |
193 | The PCL-CVS commands are still available via the keyboard. | |
194 | ||
f938eda9 CY |
195 | ** Internationalization changes |
196 | --- | |
197 | *** New language environment: Persian. | |
198 | --- | |
199 | *** New input method `vietnamese-vni'. | |
200 | ||
4e98ad15 | 201 | ** Nextstep (GNUstep / Mac OS X) port changes |
335f5ae4 | 202 | --- |
d7e642cc JD |
203 | *** Fullscreen and frame parameter fullscreen is supported. |
204 | --- | |
1a9c6830 GM |
205 | *** A file dialog is used for open/save operations initiated from the |
206 | menu/toolbar. | |

2a1e2476 | 209 | * Editing Changes in Emacs 24.3 |
c25df26e | 210 | |
d39d3c8e | 211 | ** Navigation command changes |
48de8b12 | 212 | +++ |
d39d3c8e | 213 | *** New binding `M-g c' for `goto-char'. |
48de8b12 | 214 | +++ |
d39d3c8e | 215 | *** New binding `M-g TAB' for `move-to-column'. |
48de8b12 | 216 | +++ |
d39d3c8e CY |
217 | *** `M-g TAB' (`move-to-column') prompts for a column number if called |
218 | interactively with no prefix arg. Previously, it moved to column 1. | |
219 | ||
f938eda9 | 220 | ** Search and Replace changes |
48de8b12 | 221 | +++ |
f938eda9 CY |
222 | *** Non-regexp Isearch now performs "lax" space matching. |
223 | Each sequence of spaces in the supplied search string may match any | |
224 | sequence of one or more whitespace characters, as specified by the | |
225 | variable `search-whitespace-regexp'. (This variable is also used by a | |
226 | similar existing feature for regexp Isearch). | |
48de8b12 | 227 | +++ |
f938eda9 CY |
228 | *** New Isearch command `M-s SPC' toggles lax space matching. |
229 | This applies to both ordinary and regexp Isearch. | |
48de8b12 | 230 | +++ |
f938eda9 CY |
231 | *** New option `replace-lax-whitespace'. |
232 | If non-nil, `query-replace' uses flexible whitespace matching too. | |
233 | The default is nil. | |
05b621a6 | 234 | +++ |
b9cb2387 JL |
235 | *** Global `M-s _' starts a symbol (identifier) incremental search, |
236 | and `M-s _' in Isearch toggles symbol search mode. | |
237 | `M-s c' in Isearch toggles search case-sensitivity. | |
238 | ||
48de8b12 CY |
239 | +++ |
240 | ** `C-x 8 RET' is now bound to `insert-char', which is now a command. | |
241 | `ucs-insert' is now an obsolete alias for `insert-char'. | |
242 | ||
243 | --- | |
244 | ** The `z' key no longer has a binding in most special modes. | |
245 | It used to be bound to `kill-this-buffer', but `z' is too easy to | |
246 | accidentally type. | |
247 | ||
248 | +++ | |
249 | ** New option `delete-trailing-lines' specifies whether | |
250 | M-x delete-trailing-whitespace should delete trailing lines at the end | |
251 | of the buffer. It defaults to t. | |
252 | ||
f938eda9 CY |
253 | ** Register changes |
254 | +++ | |
255 | *** `C-x r +' is now overloaded to invoke `append-to-register. | |
256 | +++ | |
257 | *** New option `register-separator' specifies the register containing | |
258 | the text to put between collected texts for use with M-x | |
259 | append-to-register and M-x prepend-to-register. | |
dd7ffad6 | 260 | |
48de8b12 | 261 | +++ |
f938eda9 | 262 | ** `C-u M-=' now counts lines/words/characters in the entire buffer. |
826b3235 | 263 | |
48de8b12 | 264 | +++ |
be755c79 RT |
265 | ** New command `C-x r M-w' (copy-rectangle-as-kill). |
266 | It copies the region-rectangle as the last rectangle kill. | |
267 | ||
05b621a6 | 268 | +++ |
f938eda9 CY |
269 | ** New option `yank-handled-properties' allows processing of text |
270 | properties on yanked text, in more ways that are more general than | |
271 | just removing them, as done by `yank-excluded-properties'. | |

2a1e2476 | 274 | * Changes in Specialized Modes and Packages in Emacs 24.3 |
b2459884 | 275 | |
f938eda9 | 276 | ** Apropos |
48de8b12 | 277 | --- |
f938eda9 CY |
278 | *** The faces used by Apropos are now directly customizable. |
279 | These faces are named `apropos-symbol', `apropos-keybinding', and so on; | |
280 | see the `apropos' Custom group for details. | |
48de8b12 CY |
281 | --- |
282 | *** The old options whose values specified faces to use were removed | |
f938eda9 CY |
283 | (i.e. `apropos-symbol-face', `apropos-keybinding-face', etc.). |
284 | ||
285 | ** Buffer Menu | |
286 | This package has been rewritten to use Tabulated List mode. | |
48de8b12 | 287 | --- |
f938eda9 CY |
288 | *** Option `Buffer-menu-buffer+size-width' is now obsolete. |
289 | Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead. | |
290 | ||
291 | ** Calendar | |
292 | ||
cad4f290 | 293 | +++ |
f938eda9 CY |
294 | *** You can customize the header text that appears above each calendar month. |
295 | See the variable `calendar-month-header'. | |
296 | ||
f1f4dba0 GM |
297 | +++ |
298 | *** New LaTeX calendar style, produced by `cal-tex-cursor-week2-summary'. | |
299 | ||
b859a383 | 300 | +++ |
f938eda9 | 301 | *** The calendars produced by cal-html include holidays. |
b859a383 | 302 | Customize `cal-html-holidays' to change this. |
ae4969c2 | 303 | |
89660017 | 304 | ** CL |
f938eda9 | 305 | |
92246540 | 306 | +++ |
89660017 | 307 | *** CL's main entry is now (require 'cl-lib). |
7c1898a7 | 308 | `cl-lib' is like the old `cl' except that it uses the namespace cleanly, |
89660017 SM |
309 | i.e. all its definitions have the "cl-" prefix (and internal definitions use |
310 | the "cl--" prefix). | |
7c1898a7 SM |
311 | |
312 | If `cl' provided a feature under the name `foo', then `cl-lib' provides it | |
313 | under the name `cl-foo' instead, with the exceptions of the few definitions | |
314 | that had to use `foo*' to avoid conflicts with pre-existing Elisp entities, | |
315 | which have not been renamed to `cl-foo*' but just `cl-foo'. | |
316 | ||
92246540 GM |
317 | The old `cl' is now deprecated and is mainly just a bunch of aliases that |
318 | provide the old non-prefixed names. Some exceptions are listed below. | |
7c1898a7 | 319 | |
69c1c2e6 | 320 | +++ |
89660017 SM |
321 | *** `cl-flet' is not like `flet' (which is deprecated). |
322 | Instead it obeys the behavior of Common-Lisp's `flet'. | |
323 | ||
69c1c2e6 | 324 | +++ |
89660017 SM |
325 | *** `cl-labels' is slightly different from `labels'. |
326 | The difference is that it relies on the `lexical-binding' machinery (as opposed | |
327 | to the `lexical-let' machinery used previously) to capture definitions in | |
328 | closures, so such closures will only work if `lexical-binding' is in use. | |
329 | ||
4ddedf94 | 330 | +++ |
f94b04fc | 331 | *** `cl-letf' is not exactly like `letf'. |
4ddedf94 GM |
332 | The only difference is in details that relate to some deprecated usage |
333 | of `symbol-function' in place forms. | |
f94b04fc | 334 | |
a05cb6e3 | 335 | +++ |
89660017 SM |
336 | *** `progv' was rewritten to use the `let' machinery. |
337 | A side effect is that vars without corresponding value are bound to nil | |
338 | rather than making them unbound. | |
339 | ||
bdd8064f | 340 | +++ |
9512f820 GM |
341 | *** The following methods of extending `setf' are obsolete |
342 | (use features from gv.el instead): | |
343 | `define-modify-macro' (use `gv-letplace') | |
031b2ea7 GM |
344 | `defsetf' (use `gv-define-simple-setter' or `gv-define-setter') |
345 | `define-setf-expander' (use `gv-define-setter' or `gv-define-expander') | |
2b4da3ff | 346 | `get-setf-method' no longer exists (see "Incompatible Lisp Changes") |

350 | |
351 | ** Customize | |
cd996018 | 352 | --- |
f938eda9 | 353 | *** `custom-reset-button-menu' now defaults to t. |
cd996018 | 354 | --- |
f938eda9 CY |
355 | *** Non-option variables are never matched in `customize-apropos' and |
356 | `customize-apropos-options' (i.e. the prefix argument does nothing for | |
357 | these commands now). | |
358 | ||
cd996018 | 359 | --- |
02969baf GM |
360 | ** `desktop-path' no longer includes the "." directory. |
361 | Desktop files are now located in ~/.emacs.d by default. | |

f938eda9 CY |
363 | ** D-Bus |
364 | ||
365 | +++ | |
366 | *** New variables `dbus-compiled-version' and `dbus-runtime-version'. | |
367 | ||
368 | +++ | |
369 | *** The D-Bus object manager interface is implemented. | |
370 | ||
371 | +++ | |
372 | *** Variables of type :(u)int32 and :(u)int64 accept floating points, | |
373 | if their value does not fit into Emacs's integer range. | |
374 | ||
375 | +++ | |
376 | *** The function `dbus-call-method' works non-blocking now, it can be | |
377 | interrupted by C-g. `dbus-call-method-non-blocking' is obsolete. | |
378 | ||
379 | +++ | |
380 | *** Signals can be sent also as unicast message. | |
381 | ||
382 | +++ | |
383 | *** The argument list of `dbus-register-signal' has been extended, | |
384 | according to the new match rule types of D-Bus. See the manual for | |
385 | details. | |
386 | ||

1116 | ** Internationalization changes |
1117 | ||
d0ce9f8c | 1118 | *** Emacs now supports display and editing of bidirectional text. |
7d301ae6 CY |
1119 | Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are |
1120 | displayed in the correct visual order as expected by users of those | |
dfdb4cad CY |
1121 | scripts. The display reordering is a "full bidirectionality" class |
1122 | implementation of the Unicode Bidirectional Algorithm (UBA). Buffers | |
1123 | with no RTL text should look exactly the same as before. | |
f4b6ba46 | 1124 | |
041d709f | 1125 | **** New buffer-local variable `bidi-display-reordering'. |
7d301ae6 | 1126 | To disable display reordering in a buffer, change this to nil. |
d20e1419 | 1127 | |
041d709f CY |
1128 | **** New buffer-local variable `bidi-paragraph-direction'. |
1129 | If nil (the default), Emacs determines the base direction of each | |
dfdb4cad CY |
1130 | paragraph from its text, as specified by the UBA. Setting the value |
1131 | to `right-to-left' or `left-to-right' forces a base direction on each | |
1132 | paragraph. | |
f4b6ba46 | 1133 | |
7d301ae6 CY |
1134 | Paragraphs with right-to-left base direction are displayed starting at |
1135 | the right window edge. | |
f1816485 | 1136 | |
dfdb4cad CY |
1137 | *** Enhanced support for characters with no glyphs in available fonts, |
1138 | or, on text terminals, characters that cannot be encoded by the | |
1139 | terminal coding system. The new option `glyphless-char-display-control' | |
1140 | specifies how to display them: as a hexadecimal code in a box, a thin | |
1141 | 1-pixel space, an empty box, etc. | |
d0ce9f8c | 1142 | |
9702b7a1 GM |
1143 | *** New input methods for Farsi and Bulgarian |
1144 | (farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic). | |
041d709f | 1145 | |
939db9ac CY |
1146 | *** `nobreak-char-display' now also highlights Unicode hyphen chars |
1147 | (U+2010 and U+2011). | |
1148 | ||
7d301ae6 | 1149 | *** New Hebrew translation of the Emacs Tutorial. |
31fd3586 GM |
1150 | Type `C-u C-h t' to choose it in case your language setup doesn't |
1151 | automatically select it. | |
1152 | ||
7d301ae6 CY |
1153 | ** An Emacs Lisp package manager is now included. |
1154 | This is a convenient way to download and install additional packages, | |
1155 | from a package repository at http://elpa.gnu.org. | |
dfdb4cad | 1156 | |
7d301ae6 CY |
1157 | *** M-x list-packages shows a list of packages, which can be |
1158 | selected for installation. | |
dfdb4cad | 1159 | |
7d301ae6 | 1160 | *** New command `describe-package', bound to `C-h P'. |
dfdb4cad | 1161 | |
7d301ae6 CY |
1162 | *** By default, all installed packages are loaded automatically when |
1163 | Emacs starts up. To disable this, set `package-enable-at-startup' to | |
1164 | nil. To specify the packages to load, customize `package-load-list'. | |
16a91140 | 1165 | |
dfdb4cad CY |
1166 | ** Custom theme changes |
1167 | ||
7d301ae6 CY |
1168 | *** New command `M-x customize-themes', which provides a convenient |
1169 | interface for enabling and disabling Custom themes. | |
dfdb4cad | 1170 | |
7d301ae6 | 1171 | *** New option `custom-theme-load-path' is the load path for themes. |
dfdb4cad CY |
1172 | Emacs no longer looks for Custom themes in `load-path'. The default |
1173 | value of `custom-theme-load-path' says to look for themes in | |
1174 | `custom-theme-directory', followed by a subdirectory of | |
1175 | `data-directory' named "themes/", which contains a small selection of | |
1176 | built-in Custom themes. | |
1177 | ||
7d301ae6 CY |
1178 | *** New option `custom-safe-themes' records known-safe theme files. |
1179 | If a theme is not in this list, Emacs queries before loading it, and | |
1180 | offers to save the theme to `custom-safe-themes' automatically. By | |
1181 | default, all themes included in Emacs are treated as safe. | |
b7d65a5f | 1182 | |
7d301ae6 | 1183 | ** Improved GTK integration |
dfdb4cad | 1184 | |
7d301ae6 | 1185 | *** GTK scroll-bars are now placed on the right by default. |
dfdb4cad CY |
1186 | The function `set-scroll-bar-mode' can change this. |
1187 | ||
7d301ae6 | 1188 | *** GTK tool bars can have just text, just images or images and text. |
dfdb4cad CY |
1189 | Customize `tool-bar-style' to choose the style. On a Gnome desktop, |
1190 | the default is taken from desktop settings. | |
1191 | ||
1192 | *** GTK tool bars can be placed on any edge of the frame. | |
7d301ae6 CY |
1193 | The frame-parameter tool-bar-position controls this. It takes the |
1194 | values top, left, right or bottom. The Options => Show/Hide menu has | |
1195 | entries for this. | |
dfdb4cad | 1196 | |
7d301ae6 CY |
1197 | *** The default colors for selected text (the `region' face) are taken |
1198 | from the GTK theme when Emacs is built with GTK. | |
dfdb4cad | 1199 | |
7d301ae6 CY |
1200 | *** Emacs uses GTK tooltips by default if built with GTK. |
1201 | You can disable this by changing `x-gtk-use-system-tooltips' to nil. | |
a5bee597 | 1202 | |
dfdb4cad CY |
1203 | ** Graphical interface changes |
1204 | ||
1205 | *** On graphical displays, the mode-line no longer ends in dashes. | |
1206 | Also, the first dash (which does not indicate anything) is just | |
1207 | displayed as a space. | |
1208 | ||
1209 | *** `menu-bar-select-buffer-function' lets you choose another operation | |
1210 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. | |
1211 | ||
1212 | *** Lucid menus and dialogs can display antialiased fonts if Emacs is | |
1213 | built with Xft. These fonts can be set via X resources, for example: | |
1214 | Emacs.pane.menubar.font: Courier-12 | |
1215 | ||
7d301ae6 | 1216 | ** Exiting changes |
dfdb4cad | 1217 | |
7d301ae6 | 1218 | *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP, |
dfdb4cad CY |
1219 | or if it receives a SIGINT signal in batch mode. |
1220 | ||
7d301ae6 CY |
1221 | *** `kill-emacs-hook' is now also run in batch mode. |
1222 | Third-party code which adds to `kill-emacs-hook' should check if they | |
1223 | do the right thing in batch mode. | |
9c524fcb | 1224 | |
041d709f | 1225 | ** Scrolling changes |
dfdb4cad | 1226 | |
041d709f | 1227 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' |
0a19a6f8 | 1228 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
7d301ae6 | 1229 | of buffer at first key-press (instead they move to top/bottom of buffer) |
550f41cd | 1230 | when `scroll-error-top-bottom' is non-nil. |
dfdb4cad CY |
1231 | |
1232 | *** New option `scroll-error-top-bottom' (see above). | |
1233 | ||
041d709f | 1234 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' |
5a97d2da | 1235 | scroll a line instead of full screen. |
dfdb4cad | 1236 | |
041d709f | 1237 | *** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 1238 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
dfdb4cad | 1239 | |
041d709f | 1240 | *** If you customize `scroll-conservatively' to a value greater than 100, |
d0f69533 EZ |
1241 | Emacs will never recenter point in the window when it scrolls due to |
1242 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | |
1243 | Previously, you needed to use `most-positive-fixnum' as the value of | |
1244 | `scroll-conservatively' to achieve the same effect. | |
dfdb4cad | 1245 | |
7d301ae6 | 1246 | *** "Aggressive" scrolling now honors the scroll margins. |
d0f69533 EZ |
1247 | If you customize `scroll-up-aggressively' or |
1248 | `scroll-down-aggressively' and move point off the window, Emacs now | |
1249 | scrolls the window so as to avoid positioning point inside the scroll | |
1250 | margin. | |
1251 | ||
7d301ae6 CY |
1252 | ** Basic SELinux support has been added. |
1253 | This requires Emacs to be linked with libselinux at build time. | |
f1a5d776 | 1254 | |
dfdb4cad CY |
1255 | *** Emacs preserves the SELinux file context when backing up. |
1256 | Also, the function `copy-file' has an extra optional argument for | |
1257 | preserving SELinux context, and the return value of `backup-buffer' | |
1258 | now includes the SELinux context. | |
f0bf7c8e | 1259 | |
dfdb4cad | 1260 | *** New functions `file-selinux-context' and `set-file-selinux-context' |
7d301ae6 | 1261 | get and set the SELinux context of a file. |
44198b6e | 1262 | |
7d301ae6 | 1263 | ** Trash changes |
dfdb4cad | 1264 | |
7d301ae6 CY |
1265 | *** `delete-by-moving-to-trash' now only affects commands that specify |
1266 | trashing. This avoids inadvertently trashing temporary files. | |
dfdb4cad | 1267 | |
7d301ae6 CY |
1268 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
1269 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
278f6845 | 1270 | |
041d709f | 1271 | ** File- and directory-local variable changes |
dfdb4cad | 1272 | |
041d709f CY |
1273 | *** You can stop directory local vars from applying to subdirectories. |
1274 | Add an element (subdirs . nil) to the alist portion of any variables | |
1275 | settings to indicate that the section should not apply to | |
1276 | subdirectories. | |
dfdb4cad | 1277 | |
041d709f CY |
1278 | *** Directory local variables can apply to some file-less buffers. |
1279 | Affected modes include dired, vc-dir, and log-edit. For example, | |
1280 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will | |
1281 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call | |
1282 | `hack-dir-local-variables-non-file-buffer' to support this. | |
dfdb4cad | 1283 | |
041d709f CY |
1284 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. |
1285 | Instead, use "eval: (minor-mode 1)". | |
c136e5cd | 1286 | |
7b447e9b GM |
1287 | *** The variable `inhibit-first-line-modes-regexps' has been renamed |
1288 | to `inhibit-local-variables-regexps'. As the name suggests, it now | |
dfdb4cad CY |
1289 | applies to ALL file local variables, not just -*- lines. The |
1290 | associated `inhibit-first-line-modes-suffixes' has been renamed in the | |
1291 | corresponding way. | |
5d907d6c | 1292 | |
0a2132ba CY |
1293 | ** Window changes |
1294 | ||
91b65361 CY |
1295 | *** The `quit-window' command now restores the last buffer displayed |
1296 | in the quitted window. | |
1297 | ||
0a2132ba CY |
1298 | *** Resizing an Emacs frame now preserves proportional window sizes, |
1299 | modulo restrictions like window minimum sizes and fixed-size windows. | |
1300 | ||
1301 | *** The behavior of `display-buffer' is now customizable in detail. | |
dfdb4cad | 1302 | |
0a2132ba CY |
1303 | **** New option `display-buffer-base-action' specifies a list of |
1304 | user-determined display "actions" (functions and optional arguments | |
1305 | for choosing the displaying window). | |
1306 | ||
1307 | This takes precedence over the default display action, which is | |
1308 | specified by `display-buffer-fallback-action'. | |
1309 | ||
1310 | **** New option `display-buffer-alist' maps buffer name regexps to | |
1311 | display actions, taking precedence over `display-buffer-base-action'. | |
1312 | ||
a0c2d0ae MR |
1313 | *** New option `window-combination-limit'. |
1314 | The new option `window-combination-limit' allows to return the space | |
1315 | obtained for resizing or creating a window more reliably to the window | |
1316 | from which such space was obtained. | |
0a2132ba | 1317 | |
a0c2d0ae MR |
1318 | *** New option `window-combination-resize'. |
1319 | The new option `window-combination-resize' allows to split a window that | |
1320 | otherwise cannot be split because it's too small by stealing space from | |
1321 | other windows in the same combination. Subsequent resizing or deletion | |
1322 | of the window will resize all windows in the same combination as well. | |
0a2132ba | 1323 | |
91b65361 CY |
1324 | *** New option `frame-auto-hide-function' lets you choose between |
1325 | iconifying or deleting a frame when burying a buffer in a dedicated | |
1326 | frame, or quitting a window showing a buffer in a frame of its own. | |
1327 | ||
0a2132ba | 1328 | *** New commands `maximize-window' and `minimize-window'. |
53964682 | 1329 | These maximize and minimize the size of a window within its frame. |
0a2132ba | 1330 | |
0a2132ba CY |
1331 | *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'. |
1332 | These functions allow to navigate through the live buffers that have | |
1333 | been shown in a specific window. | |
1334 | ||
7d301ae6 | 1335 | ** Minibuffer changes |
dfdb4cad | 1336 | |
7d301ae6 | 1337 | *** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. |
104dc9c6 GM |
1338 | This is handy for minibuffer-only frames, and is also used for the feature |
1339 | where mouse-1 pops up *Messages*"', which can now easily be changed. | |
041d709f | 1340 | |
7d301ae6 | 1341 | *** Minibuffers set `truncate-lines' to nil. |
f66eca26 | 1342 | If you want to change the value to something else, you could use |
7d301ae6 CY |
1343 | for example `minibuffer-setup-hook'. |
1344 | ||
7d301ae6 CY |
1345 | ** `auto-mode-case-fold' is now enabled by default. |
1346 | ||
7d301ae6 | 1347 | ** `backup-by-copying-when-mismatch' now defaults to t. |
f66eca26 | 1348 | |
dfdb4cad CY |
1349 | ** New basic faces `error', `warning', `success'. |
1350 | These are used to highlight text indicating failure, caution or | |
1351 | successful operation. | |
1352 | ||
1353 | ** New option `list-colors-sort' defines the color sort order | |
1354 | for `list-colors-display'. | |
1355 | ||
1356 | ** The variable `focus-follows-mouse' now always defaults to nil. | |

b350bdf2 | 1360 | |
892777ba | 1361 | ** Search changes |
dfdb4cad CY |
1362 | |
1363 | *** C-y in Isearch is now bound to `isearch-yank-kill', instead of | |
1364 | `isearch-yank-line'. | |
1365 | ||
1366 | *** M-y in Isearch is now bound to `isearch-yank-pop', instead of | |
1367 | `isearch-yank-kill'. | |
1368 | ||
1369 | *** M-s C-e in Isearch is now bound to `isearch-yank-line'. | |
1370 | ||
b2b0776e | 1371 | ** New commands `count-words-region' and `count-words'. |
dfdb4cad | 1372 | |
10607bea CY |
1373 | *** M-= is bound to `count-words-region', not `count-lines-region'. |
1374 | The `count-words-region' command, when called interactively, reports | |
1375 | the number of lines, words, and characters in the region. It is a | |
1376 | superset of the old `count-lines-region', which is now an obsolete | |
1377 | alias for it. | |
ea4f7750 | 1378 | |
ec9da840 | 1379 | ** The command `just-one-space' (M-SPC), if given a negative argument, |
1c708c1a CY |
1380 | also deletes newlines around point. |
1381 | ||
b9229673 | 1382 | ** Deletion changes |
dfdb4cad | 1383 | |
b9229673 | 1384 | *** New option `delete-active-region'. |
ddb54206 | 1385 | If non-nil, [delete] and DEL delete the region if it is active and no |
dfdb4cad | 1386 | prefix argument is given. If set to `kill', those commands kill |
ddb54206 | 1387 | instead. |
dfdb4cad | 1388 | |
59ee0542 | 1389 | *** New command `delete-forward-char', bound to [delete]. |
42d9cffa CY |
1390 | This is meant for interactive use, and obeys `delete-active-region'. |
1391 | The command `delete-char' does not obey `delete-active-region'. | |
dfdb4cad | 1392 | |
b9229673 CY |
1393 | *** `delete-backward-char' is now a Lisp function. |
1394 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
7d301ae6 CY |
1395 | However, the byte compiler now warns if it is called from Lisp; Lisp |
1396 | callers should use delete-char with a negative argument instead. | |
dfdb4cad | 1397 | |
b9229673 CY |
1398 | *** The option `mouse-region-delete-keys' has been deleted. |
1399 | ||
f9d71b42 CY |
1400 | ** Selection changes. |
1401 | ||
7d301ae6 CY |
1402 | The default handling of clipboard and primary selections has been |
1403 | changed to conform with modern X applications. In short, most | |
1404 | commands for killing and yanking text now use the clipboard, while | |
1405 | mouse commands use the primary selection. | |
b1ab31ae CY |
1406 | |
1407 | In the following, we provide a list of these changes, followed by a | |
1408 | list of steps to get the old behavior back if you prefer that. | |
1409 | ||
b1ab31ae CY |
1410 | *** `select-active-regions' now defaults to t. |
1411 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
963578d3 | 1412 | the kill ring. The selected text is put in the primary selection, if |
b1ab31ae CY |
1413 | the system possesses a separate primary selection facility (e.g. X). |
1414 | ||
1415 | **** `select-active-regions' also accepts a new value, `only'. | |
1416 | This means to only set the primary selection for temporarily active | |
1417 | regions (usually made by mouse-dragging or shift-selection); | |
1418 | "ordinary" active regions, such as those made with C-SPC followed by | |
1419 | point motion, do not alter the primary selection. | |
1420 | ||
963578d3 CY |
1421 | **** `mouse-drag-copy-region' now defaults to nil. |
1422 | ||
b1ab31ae CY |
1423 | *** mouse-2 is now bound to `mouse-yank-primary'. |
1424 | This pastes from the primary selection, ignoring the kill-ring. | |
1425 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
dfdb4cad | 1426 | |
b1ab31ae | 1427 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
dfdb4cad | 1428 | |
b1ab31ae CY |
1429 | *** `x-select-enable-primary' now defaults to nil. |
1430 | Thus, commands that kill text or copy it to the kill-ring (such as | |
1431 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
1432 | ||
1433 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now | |
dfdb4cad | 1434 | exactly equivalent to M-w, C-w, and C-y respectively. |
b1ab31ae CY |
1435 | |
1436 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already | |
1437 | non-nil by default, as Windows does not support the primary selection | |
1438 | between applications. | |
1439 | ||
1440 | *** To return to the previous behavior, do the following: | |
dfdb4cad | 1441 | |
104c2fe9 | 1442 | **** Change `select-active-regions' to nil. |
b1ab31ae CY |
1443 | **** Change `mouse-drag-copy-region' to t. |
1444 | **** Change `x-select-enable-primary' to t (on X only). | |
1445 | **** Change `x-select-enable-clipboard' to nil. | |
1446 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 1447 | |
084e6df3 | 1448 | *** Support for X cut buffers has been removed. |
dfdb4cad | 1449 | |
3fd50d5c CY |
1450 | *** X clipboard managers are now supported. |
1451 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. | |
4b80f674 | 1452 | |
dfdb4cad CY |
1453 | ** New command `C-x r N' (`rectangle-number-lines') numbers the lines |
1454 | in the current rectangle. With a prefix argument, this prompts for a | |
1455 | number to count from and for a format string. | |
99f053cf | 1456 | |
7d301ae6 | 1457 | ** `redisplay-dont-pause' now defaults to t. |
6bf7006f EZ |
1458 | This makes Emacs feel more responsive to editing commands that arrive |
1459 | at high rate, e.g. if you lean on some key, because stopping redisplay | |
1460 | in the middle (when this variable is nil) forces more expensive | |
1461 | updates later on, and Emacs appears to be unable to keep up. | |
1462 | ||
e70b5064 CY |
1463 | ** The behavior of <TAB> for active regions in Text mode has changed. |
1464 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | |
1465 | when the region is active causes Emacs to indent all the lines in the | |
1466 | region, aligning them with the line previous to the first line in the | |
1467 | region (or with the left margin if there is no previous line). | |
1468 | ||
dfdb4cad CY |
1469 | ** When `occur' is called with a prefix argument, matching strings are |
1470 | collected into the `*Occur*' buffer without line numbers. If there | |
1471 | are parenthesized subexpressions in the specified regexp, `occur' | |
1472 | reads replacement text that may contain \\& and \\N whose convention | |
1473 | follows `replace-match'. | |

eb199145 | 1476 | * Changes in Specialized Modes and Packages in Emacs 24.1 |
efeb796b | 1477 | |
041d709f | 1478 | ** Archive Mode has basic support for browsing and updating 7z archives. |
d76674bb | 1479 | |
b7c3692a | 1480 | ** BibTeX mode |
dfdb4cad | 1481 | |
2de69e00 | 1482 | *** BibTeX mode now supports biblatex. |
7d301ae6 CY |
1483 | Use the variable `bibtex-dialect' to select different BibTeX dialects. |
1484 | `bibtex-entry-field-alist' is now an obsolete alias for | |
1485 | `bibtex-BibTeX-entry-alist'. | |
1486 | ||
dfdb4cad CY |
1487 | *** New command `bibtex-search-entries', bound to C-c C-a. |
1488 | ||
b7c3692a | 1489 | *** New `bibtex-entry-format' option `sort-fields', disabled by default. |
dfdb4cad | 1490 | |
022fe7ce RW |
1491 | *** New variable `bibtex-search-entry-globally'. |
1492 | ||
7d301ae6 | 1493 | ** Browse-url |
dfdb4cad | 1494 | |
7d301ae6 | 1495 | *** New option `browse-url-mailto-function' specifies how to handle "mailto:"s. |
dfdb4cad | 1496 | |
7d301ae6 CY |
1497 | *** The default browser used by the package is now the "xdg-open" program, |
1498 | on platforms that support it. This calls your desktop's preferred browser. | |
1499 | ||
cf16af42 GM |
1500 | ** Calendar, Diary, and Appt |
1501 | ||
7d301ae6 | 1502 | *** Diary entries can contain non-printing "comments". |
548d0a63 GM |
1503 | See the variable `diary-comment-start'. |
1504 | ||
5006e634 GM |
1505 | *** Appointments can specify their individual warning times. |
1506 | See the variable `appt-warning-time-regexp'. | |
1507 | ||
0a2bb1a9 GM |
1508 | *** The function specified by `appt-disp-window-function' may be passed |
1509 | lists of arguments if multiple appointments are due at similar times. | |
1510 | If you are using a custom function for this, you should update it. | |
1511 | ||
7454f200 GM |
1512 | *** New function `diary-hebrew-birthday'. |
1513 | ||
e565dd37 GM |
1514 | *** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array' |
1515 | may no longer be nil, but must all be strings. | |
1516 | ||
7d301ae6 CY |
1517 | *** The obsolete (since Emacs 22.1) method of enabling the appt |
1518 | package by adding `appt-make-list' to `diary-hook' has been removed. | |
1519 | Use `appt-activate' instead. | |
cf16af42 | 1520 | |
cf16af42 GM |
1521 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: |
1522 | appt-issue-message (use the function appt-activate) | |
1523 | appt-visible/appt-msg-window (use the variable appt-display-format) | |
1524 | ||
cf16af42 GM |
1525 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: |
1526 | view-diary-entries, list-diary-entries, show-all-diary-entries | |
1527 | ||
551b046f | 1528 | ** CC Mode |
dfdb4cad | 1529 | |
551b046f | 1530 | *** New feature to "guess" the style in an existing buffer. |
7d301ae6 | 1531 | The main entry point is M-x c-guess. |
041d709f | 1532 | |
551b046f AM |
1533 | *** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang). |
1534 | ||
dfdb4cad | 1535 | *** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes. |
551b046f AM |
1536 | Thus C-M-a will, by default, go to the beginning of the immediate function, |
1537 | not the top level. | |
1538 | ||
dfdb4cad | 1539 | *** "Macros with semicolons" can be registered for correct indentation. |
551b046f AM |
1540 | Where such a macro ends a line (no semicolon) the next statement is no longer |
1541 | parsed as a statement continuation. | |
1542 | ||
dfdb4cad | 1543 | ** Comint and modes derived from it use the standard completion code. |
041d709f CY |
1544 | |
1545 | ** Compilation mode | |
dfdb4cad | 1546 | |
7d301ae6 | 1547 | *** Compilation mode can be used without Font Lock mode. |
041d709f CY |
1548 | `compilation-parse-errors-function' is now obsolete. |
1549 | ||
dfdb4cad | 1550 | *** New variable `compilation-filter-start', which is bound while |
7d301ae6 CY |
1551 | `compilation-filter-hook' runs. It records the start position of the |
1552 | text inserted by `compilation-filter'. | |
041d709f | 1553 | |
47a6a35f GM |
1554 | *** `compilation-error-screen-columns' and `compilation-first-column' |
1555 | are obeyed in the editing buffer. So programming language modes can | |
7d301ae6 CY |
1556 | set them, whereas previously only the value in the *Compilation* |
1557 | buffer was used. | |
1dce7193 | 1558 | |
52834b6b CY |
1559 | ** Customize |
1560 | ||
1561 | *** Customize buffers now contain a search field. | |
1562 | The search is performed using `customize-apropos'. | |
7d301ae6 | 1563 | To turn off the search field, set `custom-search-field' to nil. |
52834b6b | 1564 | |
8d5dd370 | 1565 | *** Options in customize group buffers start out hidden if not customized. |
52834b6b CY |
1566 | Use the arrow to the left of the option name to toggle visibility. |
1567 | ||
1568 | *** custom-buffer-sort-alphabetically now defaults to t. | |
1569 | ||
1570 | *** The color widget now has a "Choose" button, which allows you to | |
7d301ae6 | 1571 | choose a color via `list-colors-display'. |
52834b6b | 1572 | |
041d709f CY |
1573 | ** D-Bus |
1574 | ||
5da3be7f GM |
1575 | *** It is now possible to access buses other than the default system |
1576 | or session bus. | |
041d709f | 1577 | |
7d301ae6 | 1578 | *** The `dbus-register-method' and `dbus-register-property' functions |
5da3be7f | 1579 | optionally do not register names. |
041d709f | 1580 | |
7d301ae6 | 1581 | *** The new function `dbus-register-service' registers a known service |
dfdb4cad | 1582 | name on a D-Bus without also registering a property or a method. |
041d709f | 1583 | |
f5d6548a | 1584 | ** Dired-x |
425a25f1 | 1585 | |
7d301ae6 CY |
1586 | *** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'), |
1587 | if called with a prefix argument, read a file name from the minibuffer | |
1588 | instead of using the current buffer. | |
f5d6548a | 1589 | |
7d301ae6 | 1590 | *** The "dired local variables" feature of Dired-x is obsolete. |
817b48a7 | 1591 | The standard directory local variables feature replaces it. |
8117868f | 1592 | |
041d709f | 1593 | ** ERC changes |
7492acc9 | 1594 | |
c4077254 GM |
1595 | *** New options `erc-autojoin-timing' and `erc-autojoin-delay', |
1596 | controlling attempts to autojoin a channel. | |
041d709f CY |
1597 | |
1598 | *** New variable `erc-coding-system-precedence': If we use `undecided' | |
1599 | as the server coding system, this variable will then be consulted. | |
1600 | The default is to decode strings that can be decoded as utf-8 as | |
1601 | utf-8, and do the normal `undecided' decoding for the rest. | |
7492acc9 | 1602 | |
041d709f | 1603 | ** Eshell changes |
7492acc9 | 1604 | |
05f77e38 GM |
1605 | *** The default value of `eshell-directory-name' has changed |
1606 | to be an "eshell" directory in `user-emacs-directory'. | |
1607 | The old "~/.eshell/" directory is still used if it exists, though. | |
041d709f CY |
1608 | |
1609 | ** gdb-mi | |
dfdb4cad CY |
1610 | |
1611 | *** The M-x gdb command now uses the GDB Machine Interface protocol. | |
05f77e38 GM |
1612 | It now supports multithread non-stop debugging and simultaneous |
1613 | debugging of several threads. | |
7492acc9 | 1614 | |
18af70d0 CY |
1615 | ** Image mode |
1616 | ||
05f77e38 GM |
1617 | *** RET (`image-toggle-animation') toggles animation, if applicable. |
1618 | Animation plays once, unless the option `image-animate-loop' is non-nil. | |
18af70d0 | 1619 | |
041d709f | 1620 | ** Info |
723ee192 | 1621 | |
7d301ae6 | 1622 | *** New command M-x info-display-manual displays a named Info manual. |
2ebc3b94 GM |
1623 | If that manual is already visited in some Info buffer, it displays |
1624 | that buffer. (This is handy if you have many manuals in many *info* | |
1625 | buffers, and don't remember the name of the buffer visiting the manual | |
1626 | you want to consult.) Otherwise, it loads and displays the manual. | |
691cf4a0 | 1627 | |
24ea72d3 EZ |
1628 | *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'. |
1629 | This is for compatibility with the stand-alone Info reader program, | |
1630 | and also because `Info-edit' is a rarely used command that is disabled | |
1631 | by default. | |
1632 | ||
7d301ae6 | 1633 | ** Mail mode changes (not Message mode) |
dfdb4cad | 1634 | |
7d301ae6 | 1635 | *** New command M-x mail-add-attachment for adding MIME attachments |
7d301ae6 | 1636 | |
dfdb4cad CY |
1637 | *** The command M-x mail-attach-file was renamed to M-x mail-insert-file. |
1638 | (Its name is misleading, since it has nothing to do with MIME | |
1639 | attachments.) The old name is now an obsolete alias to the new name. | |
1640 | ||
f2c3a9eb | 1641 | ** MH-E has been updated to MH-E version 8.3.1. |
041d709f | 1642 | See MH-E-NEWS for details. |
37221432 | 1643 | |
041d709f | 1644 | ** Modula-2 mode provides auto-indentation. |
37221432 | 1645 | |
041d709f | 1646 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
3c3d4f5b | 1647 | |
5d1ac394 | 1648 | ** nXML mode no longer binds C-RET to `nxml-complete'. |
dfdb4cad CY |
1649 | Completion is now performed via `completion-at-point', bound to C-M-i |
1650 | or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the | |
1651 | default), this performs tag completion. | |
5d1ac394 | 1652 | |
f2c3a9eb CY |
1653 | ** Org mode has been updated to version 7.8.09. |
1654 | See ORG-NEWS for details. | |
1655 | ||
041d709f | 1656 | ** Prolog mode has been completely revamped, with lots of additional |
7d301ae6 CY |
1657 | functionality such as more intelligent indentation, electricity, |
1658 | support for more variants, including Mercury, and a lot more. | |
041d709f CY |
1659 | |
1660 | ** Rmail | |
1661 | ||
1662 | *** The command `rmail-epa-decrypt' decrypts OpenPGP data | |
1663 | in the Rmail incoming message. | |
1664 | ||
50419064 GM |
1665 | *** The variable `rmail-message-filter' no longer has any effect. |
1666 | This change was made in Emacs 23.1 but was not advertised at the time. | |
1667 | Try using `rmail-show-message-hook' instead. | |
1668 | ||
717a1362 | 1669 | ** Shell mode |
dfdb4cad CY |
1670 | |
1671 | *** M-x shell prompts for the shell path name if the default directory | |
1672 | is a remote file name and neither the environment variable $ESHELL nor | |
1673 | the variable `explicit-shell-file-name' is set. | |
1674 | ||
1675 | *** TAB is now bound to the standard `completion-at-point' command, | |
1676 | which now implements the pcomplete rules for shell command completion. | |
717a1362 | 1677 | |
7d301ae6 CY |
1678 | ** SMTPmail |
1679 | ||
dfdb4cad | 1680 | *** SMTPmail now uses encrypted connections (via STARTTLS) by default |
7d301ae6 CY |
1681 | if the mail server supports them. This uses either built-in GnuTLS |
1682 | support, or the starttls.el library. Customize `smtpmail-stream-type' | |
1683 | to change this. | |
1684 | ||
7d301ae6 CY |
1685 | *** The variable `smtpmail-auth-credentials' has been removed. |
1686 | By default, the information is now stored in the file ~/.authinfo. | |
dfdb4cad CY |
1687 | This was the default value of smtpmail-auth-credentials. If you had |
1688 | customized smtpmail-auth-credentials to a list of user names and | |
1689 | passwords, those settings are not used. During your first connection | |
1690 | to the smtp server, Emacs will prompt for the user name and password, | |
1691 | and offer to save them to ~/.authinfo. Or you can manually copy the | |
1692 | credentials to ~/.authinfo. For example, if you had | |
7d301ae6 CY |
1693 | |
1694 | (setq smtpmail-auth-credentials | |
1695 | '(("mail.example.org" 25 "jim" "s!cret"))) | |
1696 | ||
1697 | then the equivalent line in ~/.authinfo would be | |
1698 | ||
1699 | machine mail.example.org port 25 login jim password s!cret | |
1700 | ||
1701 | See the auth-source manual for more information, e.g. on encrypting | |
1702 | the credentials file. | |
1703 | ||
7d301ae6 | 1704 | *** The variable `smtpmail-starttls-credentials' has been removed. |
dfdb4cad | 1705 | If you had that set, you need to put |
7d301ae6 CY |
1706 | |
1707 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert" | |
1708 | ||
1709 | in your ~/.authinfo file instead. | |
1710 | ||
8ce192e3 LI |
1711 | *** SMTPmail defaults to using the address in the From: header as the |
1712 | SMTP MAIL FROM envelope. To override this, set `mail-envelope-from' | |
1713 | to the address you wish to use instead. | |
1714 | ||
34e8a2da | 1715 | ** SQL mode |
041d709f | 1716 | |
34e8a2da GM |
1717 | *** New options `sql-port', `sql-connection-alist', `sql-send-terminator', |
1718 | and `sql-oracle-scan-on'. | |
041d709f | 1719 | |
dfdb4cad | 1720 | *** New options controlling prompting for login parameters. |
34e8a2da GM |
1721 | Each supported product has a custom variable `sql-*-login-params', |
1722 | which is a list of the parameters to be prompted for before a | |
1723 | connection is established. | |
041d709f CY |
1724 | |
1725 | *** The command `sql-product-interactive' now takes a prefix argument, | |
34e8a2da | 1726 | which causes it to prompt for an SQL product. |
041d709f | 1727 | |
34e8a2da | 1728 | *** Product-specific SQL interactive commands now take prefix arguments. |
041d709f CY |
1729 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), |
1730 | given a prefix argument, prompt for a name for the SQL interactive | |
1731 | buffer. This reduces the need for calling `sql-rename-buffer'. | |
1732 | ||
1733 | *** SQL interactive modes suppress command continuation prompts, and | |
1734 | replace tabs with spaces. The first change impacts multiple line SQL | |
1735 | statements entered with C-j between each line, statements yanked into | |
1736 | the buffer and statements sent with `sql-send-*' functions. The | |
34e8a2da GM |
1737 | second prevents the MySQL and Postgres interpreters from listing |
1738 | object name completions when sent text via `sql-send-*' functions. | |
041d709f CY |
1739 | |
1740 | *** New command `sql-connect' starts a predefined SQLi session, | |
1741 | using the login parameters from `sql-connection-alist'. | |
1742 | ||
1743 | *** New "Save Connection" menu item in SQLi buffers. | |
1744 | This gathers the login params specified for the SQLi session, if it | |
1745 | was not started by a connection, and saves them as a new connection. | |
1746 | ||
34e8a2da GM |
1747 | *** New commands for listing database objects and details: |
1748 | sql-list-all and sql-list-table. | |
041d709f CY |
1749 | |
1750 | *** An API for manipulating SQL product definitions has been added. | |
1751 | ||
1752 | ** TeX modes | |
1753 | ||
1754 | *** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. | |
412b9ee5 | 1755 | |
459bba37 | 1756 | ** Tramp |
dfdb4cad | 1757 | |
7d301ae6 | 1758 | *** New inline access method "ksu" (kerberized su). |
dfdb4cad | 1759 | |
459bba37 | 1760 | *** The following access methods are discontinued: "ssh1_old", |
ea843702 | 1761 | "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish". |
dfdb4cad | 1762 | |
b011fbfe GM |
1763 | *** The user option `remote-file-name-inhibit-cache' controls whether |
1764 | remote file attributes are cached for better performance. | |
dfdb4cad | 1765 | |
58f74fe4 MA |
1766 | *** The option `ange-ftp-binary-file-name-regexp' has changed its |
1767 | default value to "". | |
dfdb4cad | 1768 | |
7d301ae6 CY |
1769 | *** Handlers for `file-selinux-context' and `set-file-selinux-context' |
1770 | for remote machines which support SELinux. | |
58f74fe4 | 1771 | |
dfdb4cad | 1772 | ** New function `url-queue-retrieve', which behaves like url-retrieve, |
a48ec60c GM |
1773 | but with limits (`url-queue-parallel-processes', `url-queue-timeout') on |
1774 | the degree of parallelism. | |
177549d0 | 1775 | |
0c32ce32 CY |
1776 | ** VC and related modes |
1777 | ||
1778 | *** Support for pulling on distributed version control systems. | |
7d301ae6 CY |
1779 | The command C-x v + (`vc-pull') runs a "pull" operation, if it is |
1780 | supported (currently with Bzr, Git, and Mercurial), to update the | |
1781 | current branch and working tree. A prefix argument means to prompt | |
1782 | the user for specifics, e.g. a pull location. | |
0c32ce32 | 1783 | |
dab3703d | 1784 | *** `vc-update' is now an alias for `vc-pull'. |
0c32ce32 CY |
1785 | |
1786 | *** Support for merging on distributed version control systems. | |
7d301ae6 CY |
1787 | The command C-x v m (`vc-merge') now runs a "merge" operation, if it |
1788 | is supported (currently with Bzr, Git, and Mercurial), to merge | |
1789 | changes from another branch into the current one. It prompts for | |
1790 | specifics, e.g. a merge source. | |
0c32ce32 | 1791 | |
2afef60a | 1792 | *** New option `vc-revert-show-diff' controls whether `vc-revert' |
bbe43420 | 1793 | shows a diff while querying the user. It defaults to t. |
2afef60a | 1794 | |
d4eb88c7 CY |
1795 | *** Log entries in some Log View buffers can be toggled to display a |
1796 | longer description by typing RET (log-view-toggle-entry-display). | |
dab3703d GM |
1797 | This is currently supported for Bzr, Git, and Mercurial (to support |
1798 | another backend, define a `log-view-expanded-log-entry-function'). | |
7d301ae6 | 1799 | In the Log View buffers made by C-x v L (`vc-print-root-log'), you can |
d4eb88c7 CY |
1800 | use this to display the full log entry for the revision at point. |
1801 | ||
1c6c854e CS |
1802 | *** New command `vc-ediff' allows visual comparison of two revisions |

6dfcbe31 | 1895 | |
7d301ae6 CY |
1896 | ** Passing a nil argument to a minor mode function call now ENABLES |
1897 | the minor mode unconditionally. This is so that you can write e.g. | |
1898 | ||
dfdb4cad | 1899 | (add-hook 'text-mode-hook 'foo-mode) |
7d301ae6 | 1900 | |
dfdb4cad CY |
1901 | to enable foo-mode in Text mode buffers, removing the need for |
1902 | `turn-on-foo-mode' style functions. This affects all mode commands | |
1903 | defined by `define-minor-mode'. If called interactively, the mode | |
1904 | command still toggles the minor mode. | |
7d301ae6 | 1905 | |
d268b4fe CY |
1906 | ** The return value of `backup-buffer' has changed. |
1907 | It is now a list of three elements, where the second element is a list | |
1908 | describing the original file's SELinux context. If Emacs or the | |
f003f294 | 1909 | system lacks SELinux support, the context list is (nil nil nil nil). |
7d301ae6 | 1910 | See "Basic SELinux support" above, under "Changes in Emacs 24.1". |
d268b4fe | 1911 | |
dfdb4cad CY |
1912 | ** `char-direction-table' and the `char-direction' function were deleted. |
1913 | They were buggy and inferior to the new support of bidirectional | |
1914 | editing introduced in Emacs 24. If you need the bidirectional | |
1915 | properties of a character, use `get-char-code-property' with the last | |
1916 | argument `bidi-class'. | |
fa6996bc | 1917 | |
470d996d TV |
1918 | ** `copy-directory' now copies the source directory as a subdirectory |
1919 | of the target directory, if the latter is an existing directory. The | |
1920 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy | |
1921 | the contents directly into a pre-existing target directory. | |
1922 | ||
9173a8fb CY |
1923 | ** For mouse click input events in the text area, the Y pixel |
1924 | coordinate in the POSITION list now counts from the top of the text | |
1925 | area, excluding any header line. Previously, it counted from the top | |
1926 | of the header line. | |
1927 | ||
7d301ae6 CY |
1928 | ** Support for "old-style" backquotes, obsolete for 10+ years, has |
1929 | been further reduced. Now a backquote not followed by a space is | |
1930 | always treated as a "new-style" backquote. Please remove all | |
1931 | "old-style" backquotes from your code. If your code uses backquotes | |
1932 | as documented in the Elisp manual, and compiles without warning, then | |
1933 | you have nothing to do in this regard. Code not following the | |
1934 | appropriate conventions may fail to compile. | |
50ab02c5 CY |
1935 | |
1936 | The most common cause of trouble seems to be an old-style backquote | |
1937 | followed by a newline. Another cause of trouble is vector notation | |
1938 | for key sequence notation: instead of [(control ,)] and [(control ')], | |
1939 | you should write [(control ?,)] and [(control ?')], which will work in | |
7d301ae6 | 1940 | older Emacsen too. |

7d301ae6 CY |
1946 | ** `view-buffer' now treats special mode-class in the same way that |
1947 | `view-file' has since Emacs 22 (i.e. it won't enable View mode if the | |

1953 | and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'. |
1954 | With these alist entries omitted, `make-frame' checks the value of the | |
1955 | variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create | |
1956 | a menu-bar or tool-bar, respectively. If the alist entries are added, | |
1957 | they override the value of `menu-bar-mode'/`tool-bar-mode'. | |
6431f2e6 | 1958 | |
7d301ae6 CY |
1959 | *** The menu bar bindings's caches are not used any more. |

fe0aa820 | 1962 | ** Regions created by mouse dragging are now normal active regions, |
dfdb4cad | 1963 | similar to those created by shift-selection (see Selection changes |

041d709f | 2053 | |
041d709f | 2054 | *** New function `bidi-string-mark-left-to-right'. |
dfdb4cad CY |
2055 | Given a string containing characters from right-to-left scripts, this |

2057 | buffer, such that any following text will be always displayed to the | |
7d301ae6 CY |
2058 | right of that string. (This works by appending an invisible Unicode |

041d709f | 2060 | |
7d301ae6 | 2061 | This is useful when the buffer has overall left-to-right paragraph |

2072 | **** New function `window-valid-p' gives non-nil for live and internal |
2073 | windows. | |
dfdb4cad | 2074 | |
24300f5f | 2075 | **** Window manipulation can deal with internal windows. |
c4682d18 MR |
2076 | Many window handling functions like `split-window', `delete-window', or |
2077 | `delete-other-windows' as well as the window resizing functions can now | |
2078 | act on any window including internal ones. | |
dfdb4cad | 2079 | |
c4682d18 MR |
2080 | *** window-total-height/-width vs window-body-height/-width. |
2081 | The function `window-height' has been renamed to `window-total-height' | |
2082 | and `window-width' has been renamed to `window-body-width'. The old | |
2083 | names are provided as aliases. Two new functions `window-total-width' | |
2084 | and `window-body-height' are provided. | |

c4682d18 MR |
2086 | *** Window parameters specific to window handling functions. |
2087 | For each window you can specify a parameter to override the default | |
2088 | behavior of a number of functions like `split-window', `delete-window' | |
ed6235ea MR |
2089 | and `delete-other-windows'. The variable `ignore-window-parameters' |
2090 | allows to ignore processing such parameters. | |
dfdb4cad | 2091 | |
c4682d18 | 2092 | *** New semantics of third argument of `split-window'. |
c4682d18 MR |
2093 | The third argument of `split-window' has been renamed to SIDE and can be |
2094 | set to any of the values 'below, 'right, 'above, or 'left to make the | |
2095 | new window appear on the corresponding side of the window that shall be | |
2096 | split. Any other value of SIDE will cause `split-window' to split the | |
2097 | window into two side-by-side windows as before. | |
dfdb4cad | 2098 | |
c4682d18 | 2099 | *** Window resizing functions. |
487ffd7a | 2100 | A new standard function for resizing windows called `window-resize' has |
c4682d18 MR |
2101 | been introduced. This and all other functions for resizing windows no |
2102 | longer delete any windows when they become too small. | |
dfdb4cad | 2103 | |
b3c0dbfd MR |
2104 | *** Deleting the selected window now selects the most recently selected |
2105 | live window on that frame instead. | |
dfdb4cad | 2106 | |
c4682d18 MR |
2107 | *** `adjust-window-trailing-edge' adjustments. |
2108 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | |
2109 | is able to resize other windows if a window adjacent to the trailing | |
2110 | edge cannot be shrunk any more. This makes its behavior more similar to | |
2111 | that of Emacs 21 without compromising, however, its inability to delete | |
2112 | windows which was introduced in Emacs 22. | |
dfdb4cad | 2113 | |
c4682d18 MR |
2114 | *** Window-local buffer lists. |
2115 | Windows now have local buffer lists. This means that removing a buffer | |
2116 | from display in a window will preferably show the buffer previously | |
2117 | shown in that window with its previous window-start and window-point | |
2118 | positions. This also means that the same buffer may be automatically | |
2119 | shown twice even if it already appears in another window. | |
dfdb4cad | 2120 | |
bee0fcef CY |
2121 | *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW, |
2122 | which if non-nil requires the buffer to be displayed in the currently | |
2123 | selected window, signaling an error otherwise. If nil, another window | |
2124 | can be used, e.g. if the selected one is strongly dedicated. | |
dfdb4cad | 2125 | |
0a2132ba | 2126 | *** `split-window-vertically' and `split-window-horizontally' renamed |
2d197ffb CY |
2127 | to `split-window-below' and `split-window-right' respectively. |
2128 | The old names are kept as aliases. | |
dfdb4cad | 2129 | |
0a2132ba CY |
2130 | *** Display actions |
2131 | ||
2132 | **** The second arg to `display-buffer' and `pop-to-buffer' is now | |
2133 | named ACTION, and takes a display action of the same form as | |
2134 | `display-buffer-base-action' (see Changes, above). A non-nil, | |
2135 | non-list value is treated specially, as the old meaning. | |
2136 | ||
2137 | **** New variable `display-buffer-overriding-action'. | |
2138 | ||
2139 | **** The procedure of `display-buffer' etc. to choose a window is | |
2140 | determined by combining `display-buffer-overriding-action', | |
2141 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', | |
2142 | and `display-buffer-fallback-action'. The second and fourth of these | |
2143 | are user-customizable variables. | |

2145 | See the docstring of `display-buffer' for details. | |
bee0fcef | 2146 | |
20d2304d CY |
2147 | *** New functions `window-state-get' and `window-state-put'. |
2148 | These functions allow to save and restore the state of an arbitrary | |
2149 | frame or window as an Elisp object. | |
2150 | ||
a2a25d24 | 2151 | ** Completion |
041d709f | 2152 | |
7d301ae6 CY |
2153 | *** New variable `completion-extra-properties' used to specify extra |
2154 | properties of the current completion: | |
a2a25d24 SM |
2155 | - :annotate-function, same as the old completion-annotate-function. |
2156 | - :exit-function, function to call after completion took place. | |
2157 | ||
7d301ae6 CY |
2158 | *** Functions on `completion-at-point-functions' can return any of the |
2159 | properties valid for `completion-extra-properties'. | |
a2a25d24 | 2160 | |
7d301ae6 | 2161 | *** `completion-annotate-function' is obsolete. |
a2a25d24 | 2162 | |
620c53a6 SM |
2163 | *** New `metadata' method for completion tables. The metadata thus returned |
2164 | can specify various details of the data returned by `all-completions': | |
2165 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | |
2166 | used to select a style in completion-category-overrides. | |
2167 | - `annotation-function' to add annotations in *Completions*. | |
2168 | - `display-sort-function' to specify how to sort entries in *Completions*. | |
2169 | - `cycle-sort-function' to specify how to sort entries when cycling. | |
2170 | ||
7d301ae6 CY |
2171 | *** `minibuffer-local-filename-must-match-map' is not used any more. |
2172 | Instead, the bindings in `minibuffer-local-filename-completion-map' | |
2173 | are combined with `minibuffer-local-must-match-map'. | |
de09aa52 CY |
2174 | |
2175 | *** New variable `completing-read-function' allows overriding the | |
2176 | behavior of `completing-read'. | |
2177 | ||
f042970d | 2178 | ** `glyphless-char-display' can now distinguish between graphical and |
16a43933 CY |
2179 | text terminal display, via a char-table entry that is a cons cell. |
2180 | ||
7d301ae6 | 2181 | ** `pre-command-hook'/`post-command-hook' are not reset to nil on error. |
f6d62986 SM |
2182 | Instead, the offending function is removed. |
2183 | ||
b1f6fa26 CY |
2184 | ** New hook types |
2185 | ||
2186 | *** New function `run-hook-wrapped' for running an abnormal hook by | |
2187 | passing the hook functions as arguments to a "wrapping" function. | |
e7bc51d0 | 2188 | Like `run-hook-with-args-until-success', it stops at the first |
5385447f | 2189 | non-nil return value. |
e7bc51d0 | 2190 | |
b1f6fa26 CY |
2191 | *** New macro `with-wrapper-hook' for running an abnormal hook as a |
2192 | set of "wrapping" filters, similar to around advice. | |
54521c99 GM |
2193 | (A version of this macro was actually added in Emacs 23.2 but was not |
2194 | advertised at the time.) | |
f6d62986 | 2195 | |
0b19b281 | 2196 | ** Debugger changes |
dfdb4cad | 2197 | |
0b19b281 | 2198 | *** New macro `condition-case-unless-debug' (this was actually added in |
1be3ca5a | 2199 | Emacs 23.1 as condition-case-no-debug, but not advertised) |
dfdb4cad | 2200 | |
0b19b281 | 2201 | *** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised. |
dfdb4cad | 2202 | |
0b19b281 | 2203 | *** Variable `stack-trace-on-error' removed. |
dfdb4cad | 2204 | |
0b19b281 CY |
2205 | *** The debugger can now "continue" from an error, which means it will |
2206 | jump to the error handler as if the debugger had not been invoked | |
2207 | instead of jumping all the way to the top-level. | |
dfdb4cad | 2208 | |
0b19b281 CY |
2209 | *** Set `debug-on-event' to enter the debugger on events like SIGUSR1. |
2210 | This can be useful when `inhibit-quit' is set. | |
d6b1d521 | 2211 | |
953cebf5 | 2212 | ** The new function `server-eval-at' allows evaluation of Lisp forms on |
37576acd | 2213 | named Emacs server instances. |
7deebf1b | 2214 | |
1b9f60cc GM |
2215 | ** `call-process' and `call-process-region' allow a `(:file "file")' spec |
2216 | to redirect STDOUT to a file. | |
7deebf1b | 2217 | |
7d301ae6 CY |
2218 | ** The function `format-time-string' now supports the %N directive, |
2219 | for higher-resolution time stamps. | |
da97a9e6 | 2220 | |
0b19b281 | 2221 | ** New input reading functions |
dfdb4cad | 2222 | |
0b19b281 CY |
2223 | *** New function `read-char-choice' reads a restricted set of |
2224 | characters, discarding any inputs not inside the set. | |
dfdb4cad | 2225 | |
0b19b281 CY |
2226 | *** The command `read-color' now requires a match for a color name |
2227 | or RGB triplet, instead of signaling an error if the user provides | |
2228 | invalid input. | |
dfdb4cad | 2229 | |
0b19b281 | 2230 | **** `facemenu-read-color' is now an alias for `read-color'. |
3ef01959 | 2231 | |
2e288d54 JB |
2232 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
2233 | The variable is now used to load all kind of supported dynamic libraries, | |
2234 | not just image libraries. The previous name is still available as an | |
2235 | obsolete alias. | |
2236 | ||
0b19b281 | 2237 | ** Syntax parsing changes |
dfdb4cad | 2238 | |
0b19b281 | 2239 | *** New variable `syntax-propertize-function'. |
04e2ce72 | 2240 | This replaces `font-lock-syntactic-keywords' which is now obsolete. |
cf38dd42 SM |
2241 | This allows syntax-table properties to be set independently from font-lock: |
2242 | just call syntax-propertize to make sure the text is propertized. | |
2243 | Together with this new variable come a new hook | |
2244 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
2245 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
2246 | as-is; and syntax-propertize-rules which provides a new way to specify | |
2247 | syntactic rules. | |
dfdb4cad | 2248 | |
0b19b281 | 2249 | *** Syntax tables support a new "comment style c" additionally to style b. |
a2e5caf7 | 2250 | |
7d301ae6 | 2251 | ** New hook `post-self-insert-hook', run after `self-insert-command'. |
041d709f | 2252 | |
4e2db1fe | 2253 | ** frame-local variables cannot be let-bound any more. |
041d709f | 2254 | |
15de15c6 | 2255 | ** Major and minor mode changes |
dfdb4cad | 2256 | |
0b19b281 CY |
2257 | *** `set-auto-mode' now respects mode: local variables at the end of files, |
2258 | as well as those in the -*- line. | |
dfdb4cad | 2259 | |
15de15c6 CY |
2260 | *** `prog-mode' is a new major mode from which programming modes |
2261 | should be derived. | |
dfdb4cad | 2262 | |
15de15c6 CY |
2263 | **** `prog-mode-hook' can be used to enable features for programming |
2264 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable | |
2265 | on-the-fly spell checking for comments and strings. | |
dfdb4cad | 2266 | |
15de15c6 CY |
2267 | *** New hook `change-major-mode-after-body-hook', run by |
2268 | `run-mode-hooks' just before any other mode hooks. | |
dfdb4cad | 2269 | |
7a9a2fc6 GM |
2270 | *** Enabled globalized minor modes can be disabled in specific major modes. |
2271 | If the global mode is global-FOO-mode, then run (FOO-mode -1) in the | |
2272 | major mode's hook, where FOO-mode toggles the mode on a per-buffer basis. | |
dfdb4cad | 2273 | |
feb8a83a | 2274 | *** `define-minor-mode' accepts new keywords :variable, :after-hook. |
f44379e7 | 2275 | |
7d301ae6 CY |
2276 | ** File-handling changes |
2277 | ||
7d301ae6 | 2278 | *** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
2279 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
2280 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
2281 | argument is supplied (see Trash changes, above). | |
53967e09 | 2282 | |
7d301ae6 | 2283 | *** New file predicates: `file-equal-p', `file-in-directory-p'. |
ec70a47d | 2284 | |
4039c786 CY |
2285 | ** Tool-bars can display separators. |
2286 | Tool-bar separators are handled like menu separators in menu-bar maps, | |
94975270 | 2287 | i.e. via menu entries of the form `(menu-item "--")'. |
9317e499 | 2288 | |
00fe2df1 JL |
2289 | ** Image API |
2290 | ||
18af70d0 CY |
2291 | *** Animated images support (currently animated gifs only). |
2292 | ||
2293 | **** `image-animated-p' returns non-nil if an image can be animated. | |
2294 | ||
2295 | **** `image-animate' animates a supplied image spec. | |
2296 | ||
2297 | **** `image-animate-timer' returns the timer object for an image that | |
2298 | is being animated. | |
00fe2df1 | 2299 | |
7cb76fe0 GM |
2300 | *** `image-extension-data' has been renamed to `image-metadata'. |
2301 | The old name is an obsolete alias to the new one. | |
1546c559 | 2302 | |
b4ac6e8c GM |
2303 | *** Image mode can view any image type that ImageMagick supports. |
2304 | This requires Emacs to be built with ImageMagick support. | |
7d301ae6 CY |
2305 | |
2306 | **** New function `imagemagick-types', defined if ImageMagick support | |
2307 | is enabled, returns a list of image file extensions that your | |
2308 | ImageMagick installation supports. | |
2309 | ||
2310 | **** New function `imagemagick-register-types' enables ImageMagick | |
2311 | image types in Image mode and in `create-image' and other helper | |
2312 | functions. | |
2313 | ||
2314 | **** New option `imagemagick-types-inhibit' excludes certain | |
2315 | ImageMagick image types from `imagemagick-register-types'. | |
2316 | ||
7d301ae6 CY |
2317 | **** With ImageMagick support, there are extra Image mode commands to |
2318 | resize and rotate images: `image-transform-fit-to-height', | |
2319 | `image-transform-fit-to-width', `image-transform-set-rotation', and | |
2320 | `image-transform-set-scale'. | |
041d709f | 2321 | |
7d301ae6 CY |
2322 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
2323 | passes it to the mail user agent function. This argument specifies an | |
2324 | action for returning to the caller after finishing with the mail. For | |
2325 | example, this is used by Rmail to optionally delete a mail window. | |
b4ac6e8c | 2326 | |
71c17aec | 2327 | ** XML and HTML parsing |
483ab230 CY |
2328 | If Emacs is compiled with libxml2 support, there are two new |
2329 | functions: `libxml-parse-html-region' (which parses "real world" HTML) | |
2330 | and `libxml-parse-xml-region' (which parses XML). Both return an | |
2331 | Emacs Lisp parse tree. | |
4b9832a6 | 2332 | |
7d301ae6 | 2333 | ** Networking and encryption changes |
e2574f2c | 2334 | |
7d301ae6 CY |
2335 | *** `open-network-stream' can now be used to open an encrypted stream. |
2336 | It now accepts an optional `:type' parameter for initiating a TLS | |
2337 | connection, directly or via STARTTLS. To do STARTTLS, additional | |
2338 | parameters (`:end-of-command', `:success', `:capabilities-command') | |
2339 | must also be supplied. | |
2340 | ||
2341 | *** New library gnutls.el. | |
dfdb4cad CY |
2342 | The new function `gnutls-available-p' returns non-nil if Emacs is |
2343 | built with GnuTLS support. The main entry points are | |
2344 | `open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use | |
2345 | these functions through `open-network-stream', because that can | |
7d301ae6 CY |
2346 | upgrade connections through STARTTLS opportunistically or use plain |
2347 | SSL, depending on your needs. For debugging, set `gnutls-log-level' | |
2348 | greater than 0. | |
2349 | ||
7d301ae6 CY |
2350 | *** New primitive `secure-hash' that supports many secure hash algorithms: |
2351 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library | |
2352 | sha1.el has been removed. The `sha1' feature is provided by default. | |
71c17aec | 2353 | |
a6020335 MH |
2354 | ** Isearch |
2355 | ||
2356 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | |
2357 | ||
9326ba26 CY |
2358 | ** Progress reporters can now "spin". |
2359 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
2360 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
2361 | time you call `progress-reporter-update' on that progress reporter, | |
2362 | with a nil or omitted VALUE argument, the reporter message is | |
2363 | displayed with a "spinning bar". | |
2364 | ||
3e214b50 JB |
2365 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is |
2366 | being reverted, even if the buffer has a local `revert-buffer-function'. | |
2367 | ||
001bf877 GM |
2368 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. |
2369 | If delayed-warnings-list is non-nil, the command loop calls | |
7d301ae6 CY |
2370 | `delayed-warnings-hook' after `post-command-hook'. At present, this |
2371 | is only used by Emacs on some platforms to display warnings during | |
2372 | startup, which might otherwise not be noticed. This uses the | |
2373 | functions `display-delayed-warnings' and `collapse-delayed-warnings'. | |
001bf877 | 2374 | |
6420d28b CY |
2375 | ** rx.el has a new `group-n' construct for explicitly numbered groups. |
2376 | ||
dac86404 GM |
2377 | ** New function `make-composed-keymap' that constructs a new keymap |
2378 | from multiple input maps. You can use this to make a keymap that | |
2379 | inherits from multiple maps, eg: | |
2380 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) | |
43dc9f5b | 2381 | |
c8f6ec5c GM |
2382 | ** New function `string-prefix-p'. |
2383 | (This was actually added in Emacs 23.2 but was not advertised at the time.) | |
2384 | ||
27f7ef2f | 2385 | ** New reader macro ## that stands for the empty symbol. |
43dc9f5b AS |
2386 | This means that the empty symbol can now be read back. Also, #: by itself |
2387 | (when not immediately followed by a possible symbol character) stands for | |
2388 | an empty uninterned symbol. | |
041d709f | 2389 | |
fead402d CY |
2390 | ** New math functions `isnan', `copysign', `frexp', `ldexp'. |
2391 | ||
7d301ae6 | 2392 | ** The following functions and variables are obsolete: |
041d709f | 2393 | |
05f77e38 GM |
2394 | *** `tooltip-use-echo-area' is obsolete. |
2395 | Rather than setting this to t, disable Tooltip mode instead. | |
2396 | ||
041d709f CY |
2397 | *** buffer-substring-filters is obsolete. |
2398 | Use `filter-buffer-substring-functions' instead. | |
2399 | ||
2400 | *** `byte-compile-disable-print-circle' is obsolete. | |
2401 | ||
2402 | *** `deferred-action-list' and `deferred-action-function' are obsolete. | |
f160676e GM |
2403 | Use `post-command-hook' instead. |
2404 | ||
67e729a5 CY |
2405 | *** `font-lock-maximum-size' is obsolete. |
2406 | ||
eb199145 GM |
2407 | \f |
2408 | * Changes in Emacs 24.1 on non-free operating systems | |
d53a60a6 | 2409 | |
7a22e700 | 2410 | ** On MS Windows, Emacs warns when using the obsolete init file _emacs, |
a2f0118c GM |
2411 | and also when HOME is set to C:\ by default. |
2412 | ||
7a22e700 | 2413 | ** New configure.bat options |
04779484 | 2414 | |
7a22e700 | 2415 | *** --enable-checking builds Emacs with extra runtime checks. |
e3aef5c6 | 2416 | |
7a22e700 | 2417 | *** --distfiles specifies files to be included in binary distribution. |
e2574f2c | 2418 | |
7a22e700 OK |
2419 | *** --without-gnutls disables automatic GnuTLS detection. |
2420 | ||
a0d363f4 | 2421 | *** --lib for general library linkage, works with the USER_LIBS build variable. |
e2574f2c | 2422 | |
0a19a6f8 | 2423 | ** New make target `dist' to create binary distribution for MS Windows. |
e3aef5c6 | 2424 | |
1f5e1a16 GM |
2425 | ** The Lisp function `w32-default-color-map' is now obsolete. |
2426 | (It is only used internally in the Emacs C code.) | |
5430d399 | 2427 | |
1f5e1a16 GM |
2428 | ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but |
2429 | reappear on mouse-over. (Requires OS X 10.6 or later.) | |
04e2ce72 | 2430 | |
ad7c802c CY |
2431 | ** On Mac OS X, dragging a file into Emacs visits the file, like on |
2432 | other platforms, rather than inserting its contents into the buffer. | |
