95a32efb | 24 | * Installation Changes in Emacs 24.4 |
7c3d167f | 25 | |
ffdc270a | 26 | ** Emacs can be compiled with ACL support. |
7c3d167f RF |
27 | This happens by default if a suitable support library is found at |
28 | build time, like libacl on GNU/Linux. To prevent this, use the | |
ffdc270a | 29 | configure option `--disable-acl'. |
7c3d167f | 30 | |
2f23b3ab | 31 | ** Emacs can be compiled with file notification support. |
671d4bfc GM |
32 | This happens by default if a suitable system library is found at |
33 | build time. To prevent this, use the configure option | |
34 | `--with-file-notification-no'. See below for file-notify features. | |
35 | FIXME? This feature is not available for the Nextstep port. (?) | |
2f23b3ab | 36 | |
335142f9 GM |
37 | ** The configure option `without-compress-info' has been generalized, |
38 | and renamed to `without-compress-install'. It now prevents compression | |
39 | of _any_ files during installation. | |
40 | ||
aec32f66 | 41 | ** The configure option --with-crt-dir has been removed. |
f1e496a5 EZ |
42 | It is no longer needed, as the crt*.o files are no longer linked |
43 | specially. | |
44 | ||
ae7bfbf5 JB |
45 | ** Directories passed to configure option `--enable-locallisppath' are |
46 | no longer created during installation. | |
47 | ||
313546eb LMI |
48 | ** Emacs can be compiled with zlib support. If this library is present |
49 | (which it normally is on most systems), the function | |
7699d09e LMI |
50 | `zlib-decompress-region' becomes available, which can decompress gzip- |
51 | and zlib-format compressed data. | |
313546eb | 52 | |
9524a13d JD |
53 | --- |
54 | ** Emacs for NS (OSX, GNUStep) can be built with ImageMagick support. | |
55 | pkg-config is required to find ImageMagick libraries. | |
56 | ||
3fa2054e JD |
57 | ** For OSX >= 10.5, the Core text based font backend from the Mac port is used. |
58 | For GNUStep and OSX 10.4 the old backend is used. | |
59 | To use the old backend by default, do on the command line: | |
60 | % defaults write org.gnu.Emacs FontBackend ns | |

95a32efb | 63 | * Startup Changes in Emacs 24.4 |
c57b2d76 | 64 | |
17e0445b GM |
65 | +++ |
66 | ** When initializing `load-path', an empty element in the EMACSLOADPATH | |
67 | environment variable (either leading, e.g., ":/foo"; trailing, e.g., | |
68 | "/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default | |
69 | load-path (the one that would have been used if EMACSLOADPATH was unset). | |
70 | This makes it easier to _extend_ the load-path via EMACSLOADPATH | |
71 | (previously, EMACSLOADPATH had to specify the complete load-path, | |
72 | including the defaults). (In older versions of Emacs, an empty element | |
73 | was replaced by ".", so use an explicit "." now if that is what you want.) | |
74 | ||
a0833f62 GM |
75 | +++ |
76 | ** The -L option, which normally prepends its argument to load-path, | |
2df10228 GM |
77 | will instead append, if the argument begins with `:' (or `;' on MS Windows; |
78 | i.e., `path-separator'). | |
a0833f62 | 79 | |
06a4f110 GM |
80 | +++ |
81 | ** If you use either site-load.el or site-init.el to customize the dumped | |
82 | Emacs executable, any changes to `load-path' that these files make | |
83 | will no longer be present after dumping. To affect a permanent change | |
84 | to `load-path', use the `--enable-locallisppath' option of `configure'. | |

95a32efb | 87 | * Changes in Emacs 24.4 |
c6c08d3f | 88 | |
0a12fca0 EZ |
89 | +++ |
90 | ** Emacs now supports menus on text-mode terminals. | |
91 | If the terminal supports a mouse, clicking on the menu bar, or on | |
92 | sensitive portions of the mode line or header line, will drop down the | |
93 | menu defined at that position. Likewise, clicking C-mouse-2 or | |
94 | C-mouse-2 or C-mouse-3 on the text area will pop up the menus defined | |
95 | for those locations. | |
96 | ||
97 | If the text terminal does not support a mouse, you can activate the | |
98 | first menu-bar menu by typing F10, which invokes `menu-bar-open'. | |
99 | ||
100 | If you want the previous behavior, whereby F10 invoked `tmm-menubar', | |
101 | customize the option `tty-menu-open-use-tmm' to a non-nil value. | |
102 | (Typing M-` will always invoke `tmm-menubar', even if | |
103 | `tty-menu-open-use-tmm' is nil.) | |
104 | ||
29f47822 LL |
105 | ** Key ? also describes prefix bindings like C-h. |
106 | ||
ed4fd9c5 DA |
107 | +++ |
108 | ** `cache-long-line-scans' has been renamed to `cache-long-scans' | |
109 | because it affects caching of paragraph scanning results as well. | |
110 | ||
61a5bb85 BG |
111 | +++ |
112 | ** `apropos-variable' is now `apropos-user-option' | |
113 | `apropos-user-option' shows all user options while `apropos-variable' | |
114 | shows all variables. When called with a universal prefix argument, | |
115 | the two commands swap their behaviors. When `apropos-do-all' is | |
116 | non-nil, they output the same results. | |
117 | ||
c6c08d3f GM |
118 | +++ |
119 | ** `eval-defun' on an already defined defcustom calls the :set function, | |
120 | if there is one. | |
121 | ||
97a1cd9d GM |
122 | ** If the new variable `enable-dir-local-variables' is nil, |
123 | directory local variables are ignored. May be useful for some modes | |
124 | that want to ignore directory-locals while still respecting file-locals. | |
125 | ||
5dea55d2 CY |
126 | ** The option `set-mark-default-inactive' has been deleted. |
127 | This unfinished feature was introduced by accident in Emacs 23.1; | |
128 | simply disabling Transient Mark mode does the same thing. | |
129 | ||
dc646358 CK |
130 | ** `initial-buffer-choice' can now specify a function to set up the |
131 | initial buffer. | |
132 | ||
90582f05 GM |
133 | ** The *Messages* buffer is created in a new major mode `messages-buffer-mode', |
134 | and read-only. Code that might create the *Messages* buffer should | |
135 | call the function `messages-buffer' to do so and set the mode. | |
136 | ||
ef099a94 MN |
137 | ** `remember-notes' creates a buffer whose content is saved on kill-emacs. |
138 | You may think of it as a *scratch* buffer whose content is preserved. | |
139 | In fact, it was designed as a replacement for *scratch* buffer and can | |
140 | be used that way by setting `initial-buffer-choice' to `remember-notes' | |
141 | and `remember-notes-buffer-name' to "*scratch*". Without the second | |
142 | change, *scratch* buffer will still be there for notes that do not | |
143 | need to be preserved. | |
144 | ||
cbee2131 PE |
145 | ** `write-region-inhibit-fsync' now defaults to t in batch mode. |
146 | ||
7c3d167f RF |
147 | ** ACL support has been added. |
148 | +++ | |
149 | *** Emacs preserves the ACL entries of files when backing up. | |
150 | +++ | |
151 | *** New functions `file-acl' and `set-file-acl' get and set the ACL | |
66447e07 EZ |
152 | entries of a file. On GNU/Linux, the POSIX ACL interface is used via |
153 | libacl. On MS-Windows, the NT Security APIs are used to emulate the | |
154 | POSIX ACL interfaces. | |
7c3d167f | 155 | |
99548339 | 156 | ** New option `scroll-bar-adjust-thumb-portion'. |
a219080b EZ |
157 | Available only on X, this option allows to control over-scrolling |
158 | using the scroll bar (i.e. dragging the thumb down even when the end | |
159 | of the buffer is visible). | |
99548339 | 160 | |
708e05f6 LMI |
161 | ** New function `add-face-text-property' has been added, which can be |
162 | used to conveniently prepend/append new face attributes to text. | |
163 | ||
a6d63d97 GM |
164 | ** In compiled Lisp files, the header no longer includes a timestamp. |
165 | ||
4e3f9230 YM |
166 | ** Multi-monitor support has been added. |
167 | ||
168 | *** New functions `display-monitor-attributes-list' and | |
169 | `frame-monitor-attributes' can be used to obtain information about | |
170 | each physical monitor on multi-monitor setups. | |
171 | ||
cf13177e YM |
172 | *** The functions `display-pixel-width' and `display-pixel-height' now |
173 | behave consistently among the platforms: they return the pixel width | |
174 | or height for all physical monitors associated with the given display | |
175 | as just they were on X11. To get information for each physical | |
176 | monitor, use the new functions above. Similar notes also apply to | |
177 | `x-display-pixel-width', `x-display-pixel-height', `display-mm-width', | |
178 | `display-mm-height', `x-display-mm-width', and `x-display-mm-height'. | |
179 | ||
652b969e | 180 | ** New macro `define-alternatives' can be used to define generic commands. |
61e56e2c JB |
181 | Generic commands are interactive functions whose implementation can be |
182 | selected among several alternatives, as a matter of user preference. | |
183 | ||
f88ac3bb | 184 | ** New hooks `focus-in-hook', `focus-out-hook'. |
f6083c67 | 185 | These are normal hooks run when an Emacs frame gains or loses input focus. |
f88ac3bb | 186 | |
18c26d81 JD |
187 | ** The blink cursor stops blinking after 10 blinks (default) on X and NS. |
188 | You can change the default by customizing the variable blink-cursor-blinks. | |
189 | Also timers for blinking are stopped when no blinking is done, so Emacs does | |
190 | not consume CPU cycles. | |
191 | ||
6585d561 JB |
192 | ** New command `frameset-to-register' is now bound to `C-x r f', replacing |
193 | `frame-configuration-to-register'. It offers similar functionality, plus | |
194 | some enhancements, like the ability to restore deleted frames. Command | |
195 | `frame-configuration-to-register' is still available, but unbound. | |
196 | ||
6950f152 KH |
197 | ** The command `quail-help' is deleted. Use `C-h C-\' |
198 | (`describe-input-method') instead. | |
199 | ||
da9ea6d9 DG |
200 | ** The default value of `comment-use-global-state' is changed to t, |
201 | and this variable has been marked obsolete. | |
202 | ||
0a749fa0 MN |
203 | ** `fill-single-char-nobreak-p' prevents fill from breaking a line after |
204 | a 1-letter word, which is an error according to Polish and | |
205 | Czech typography rules. To globally enable this feature, evaluate: | |
206 | ||
207 | (add-hook 'fill-nobreak-predicate 'fill-single-char-nobreak-p) | |

95a32efb | 210 | * Editing Changes in Emacs 24.4 |
4f0552c2 | 211 | |
da048127 SM |
212 | ** `electric-indent-mode' is enabled by default. |
213 | ||
d5ccb7be | 214 | ** Uniquify is enabled by default with post-forward-angle-brackets style. |
4e36a6a6 | 215 | |
7818df11 | 216 | ** Command `rectangle-mark-mode' bound to C-x SPC makes a rectangular region. |
3472b6c6 SM |
217 | Most commands are still unaware of it, but kill/yank do work on the rectangle. |
218 | ||
b7d5bd82 TL |
219 | ** C-x TAB enters a transient interactive mode. |
220 | You can then use the left/right cursor keys to move the block of text. | |
221 | ||
3ccc2d28 XF |
222 | ** `tab-stop-list' is now implicitly extended to infinity by repeating |
223 | the last step. Its default value is changed to nil which means a tab | |
224 | stop every `tab-width' columns. | |
b7d5bd82 | 225 | |
0aa3616e SB |
226 | ** `split-window' is no longer a command, just a non-interactive function. |
227 | As a command it was a special case of `split-window-below', and as such | |
228 | superfluous. After being reimplemented in Lisp, its interactive form | |
229 | was mistakenly retained. | |
230 | ||
a45b7647 JL |
231 | ** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized', |
232 | bound to <f11> and M-<f10>, respectively. | |
37f38bca | 233 | |
958614cf GM |
234 | ** In keymaps where SPC scrolls, S-SPC now scrolls in the reverse direction. |
235 | Eg View mode, etc. | |
236 | ||
4c672a0f EZ |
237 | +++ |
238 | ** New option `visual-order-cursor-movement'. | |
239 | If this is non-nil, cursor motion with arrow keys will follow the | |
240 | visual order of characters on the screen: <left> always moves to the | |
241 | left, <right> always moves to the right, disregarding the surrounding | |
242 | bidirectional context. | |
243 | ||
c8af480d LL |
244 | ** All register commands can now show help with preview. |
245 | ||
0b1619da LL |
246 | ** New command `kmacro-to-register' to store keyboard macros in registers. |
247 | ||
ac2f8659 MY |
248 | ** Shell Script mode |
249 | ||
250 | *** `sh-mode' now has the mode own `add-log-current-defun-function'. | |
251 | You can pick the name of the function and the variables with `C-x 4 a'. | |
252 | ||

95a32efb | 254 | * Changes in Specialized Modes and Packages in Emacs 24.4 |
4f0552c2 | 255 | |
7ae3ae39 SM |
256 | ** CUA-mode |
257 | CUA-mode was changed to make use of delete-selection-mode and | |
258 | shift-select-mode. So you can now enable it independently from | |
259 | transient-mark-mode, delete-selection-mode, and shift-select-mode. | |
260 | As a result, cua-highlight-region-shift-only is obsolete | |
261 | (you can disable transient-mark-mode to get the same result). | |
262 | ||
4b72c12b | 263 | ** `delete-selection-mode' can be used without transient-mark-mode. |
f345395c | 264 | |
fdab3d0b | 265 | ** prolog-use-smie has been removed, along with the non-SMIE indentation code. |
eb89dc14 | 266 | |
71e3276b | 267 | ** SMIE indentation can be customized via `smie-config'. |
a67c4ae0 | 268 | The customization can be guessed by Emacs by providing a sample indented |
71e3276b SM |
269 | file and letting SMIE learn from it. |
270 | ||
271 | ** sh-script now uses its SMIE indentation algorithm by default. | |
272 | ||
26b3353a TH |
273 | ** `eshell' now supports visual subcommands and options |
274 | Eshell has been able to handle "visual" commands (interactive, | |
275 | non-line oriented commands such as top that require display | |
276 | capabilities not provided by eshell) by running them in an Emacs | |
277 | terminal emulator. See `eshell-visual-commands'. | |
278 | ||
279 | This feature has been extended to subcommands and options that make a | |
280 | usually line-oriented command a visual command. Typical examples are | |
281 | "git log" and "git <command> --help" which display their output in a | |
282 | pager by default. See `eshell-visual-subcommands' and | |
283 | `eshell-visual-options'. | |
284 | ||
3179b276 LMI |
285 | ** If your Emacs is compiled with libxml2 support, you can use the new |
286 | built-in web browser `eww'. | |
287 | ||
c034abda BG |
288 | ** `remember' can now store notes in separates files |
289 | You can use the new function `remember-store-in-files' within the | |
290 | `remember-handler-functions' option. | |
291 | ||
292 | See `remember-data-directory' and `remember-directory-file-name-format' | |
293 | for new options related to this function. | |
deee89ff | 294 | |
fba1763d | 295 | ** More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>. |

318 | *** All delphi-* variables and functions have been renamed to opascal-*. | |
02f473a4 JB |
319 | *** `delphi-newline-always-indents' is not supported any more. |
320 | Use `electric-indent-mode' instead. | |

328 | The default separator is changed to allow surrounding spaces around the comma. | |
329 | ||
4b72c12b SM |
330 | ** The backtrace debugger and local variables: |
331 | *** The debugger's `e' command evaluates the code in the context at point. | |
332 | This includes using the lexical environment at point, which means that | |
333 | `e' now lets you access lexical variables as well. | |
334 | *** The backtrace debugger can display local vars with `v'. | |
335 | ||

348 | ||
349 | *** New option `calendar-day-header-array'. | |

f6e8d3c1 | 357 | ** VC and related modes |
7aa7fff0 | 358 | |
f6e8d3c1 XF |
359 | *** In VC directory mode, `D' displays diffs between VC-controlled |
360 | whole tree revisions. | |
361 | ||
362 | *** In VC directory mode, `L' lists the change log for the current VC | |
363 | controlled tree in a window. | |
364 | ||
d052d3bd XF |
365 | *** In VC directory mode, `I' shows a log of changes that will be |

63191d9f XF |
368 | *** `C-x v G' (globally) and `G' (in VC directory mode) ignores a file |
369 | under current version control system. When called with a prefix | |
370 | argument, you can remove a file from the ignored file list. | |
7aa7fff0 | 371 | |
98ccf24e XF |

382 | ** Calc |
383 | ||
384 | *** Calc by default now uses the Gregorian calendar for all dates, and | |
385 | uses January 1, 1 AD as its day number 1. Previously Calc used the | |
386 | Julian calendar for dates before September 14, 1752, and it used | |
387 | December 31, 1 BC as its day number 1; the new scheme is more | |
388 | consistent with Calendar's calendrical system and day numbering. | |
389 | ||
390 | *** The new variable `calc-gregorian-switch' lets you configure the | |
391 | date when Calc switches from the Julian to the Gregorian calendar. | |
392 | Nil, the default value, means to always use the Gregorian calendar. | |
393 | The value (YEAR MONTH DAY) means to start using the Gregorian calendar | |
394 | on the given date. | |
395 | ||

401 | auto-saves of the desktop. | |
402 | ||
b958c0ad | 403 | *** `desktop-restore-frames', enabled by default, allows saving and |
6585d561 | 404 | restoring the frame/window configuration (frameset). Additional options |
36bec1b6 | 405 | `desktop-restore-in-current-display', `desktop-restore-reuses-frames' |
6585d561 | 406 | and `desktop-restore-forces-onscreen' offer further customization. |

412 | ** ERC |
413 | ||
414 | *** New option `erc-accidental-paste-threshold-seconds'. | |
415 | If set to a number, this can be used to avoid accidentally paste large | |
416 | amounts of data into the ERC input. | |
417 | ||
ed02dcfa RS |
418 | ** EPA |
419 | ||
420 | *** New option `epa-mail-aliases'. | |
421 | ||
422 | You can set this to a list of alias expansions for keys to use | |
423 | in `epa-mail-encrypt'. | |
424 | ||
425 | If one element of the variable's value is ("foo@bar.com" "foo@hello.org"), | |
426 | that means: when one of the recipients of the message being encrypted | |
427 | is `foo@bar.com', encrypt the message for `foo@hello.org' instead. | |
428 | ||
429 | If one element of the variable's value is ("foo@bar.com"), | |
430 | that means: when one of the recipients of the message being encrypted | |
431 | is `foo@bar.com', ignore that name as regards encryption. | |
432 | This is useful to avoid a query when you have no key for that name. | |

474 | It also has an optional frame argument, which can be used by Lisp | |
475 | callers to fit the image to a frame other than the selected frame. | |
476 | ||

477 | ** Info |
478 | ||
479 | *** New face `info-index-match' is used to highlight matches in index | |

481 | `info-apropos'. | |
482 | ||

486 | will cycle through faces in `hi-lock-face-defaults' without prompting. | |

491 | using the next face automatically. | |
492 | ||
d289938a | 493 | ** Search and Replace |
279f9b06 | 494 | |
e5e4a942 JL |
495 | *** New global command `M-s .' (`isearch-forward-symbol-at-point') |
496 | starts a symbol (identifier) incremental search forward with the | |
497 | symbol found near point added to the search string initially. | |
498 | ||
279f9b06 JL |
499 | *** `C-x 8 RET' in Isearch mode reads a character by its Unicode name |
500 | and adds it to the search string. | |
501 | ||
2db59b1d XF |
502 | *** `M-s i' in Isearch mode toggles the variable `isearch-invisible' |
503 | between nil and the value of the option `search-invisible' (or `open' | |
504 | when it's nil). | |
01dea85f | 505 | |
d289938a JL |

507 | and opens overlays with hidden text when `search-invisible' is `open'. | |
508 | ||
80fa505f AM |

510 | *** By default, prefix arguments do not now terminate Isearch mode. | |
511 | Set `isearch-allow-prefix' to nil to restore old behavior. | |
512 | ||
6e8cfc81 JL |
513 | *** More Isearch commands accept prefix arguments, namely |
514 | `isearch-printing-char', `isearch-quote-char', `isearch-yank-word', | |
515 | `isearch-yank-line'. | |
516 | ||
a22289f7 JL |
517 | *** Word search now matches whitespace at the beginning/end |
518 | of the search string if it contains leading/trailing whitespace. | |
519 | In an incremental word search or when using a non-nil LAX argument | |
520 | of `word-search-regexp', the lax matching can also match part of | |
521 | the first word (in addition to the lax matching of the last word). | |
522 | The same rules are now applied to the symbol search with the difference | |
523 | that it matches symbols, and non-symbol characters between symbols. | |

8b62d742 SM |
539 | ** trace-function was largely rewritten. |
540 | New features include: | |
541 | - no prompting for the destination buffer, unless a prefix-arg was used. | |
542 | - additionally to prompting for a destination buffer, when a prefix-arg is | |
543 | used, the user can enter a "context", i.e. Lisp expression whose value at the | |
544 | time the function is entered/exited will be printed along with the function | |
545 | name and arguments. Useful to trace the value of (current-buffer) or | |
546 | (point) when the function is invoked. | |
547 | ||
9631677d SS |
548 | ** New command `delete-duplicate-lines' has new types of operation: |
549 | When its arg ADJACENT is non-nil (when called interactively with C-u C-u) | |
c38a186c JL |
550 | it works like the utility `uniq'. Otherwise by default it deletes |
551 | duplicate lines everywhere in the region without regard to adjacency. | |
02f473a4 JB |
552 | When its arg KEEP-BLANKS is non-nil (when called interactively with |
553 | C-u C-u C-u), duplicate blank lines are preserved. | |

555 | ** New `cycle-spacing' command allows cycling between having just one |
556 | space, no spaces, or reverting to the original spacing. Like | |

558 | leave different number of spaces. | |

560 | ** Todo mode has been rewritten and enhanced. |
561 | New features include: | |
562 | - support for multiple todo files and archive files of done items; | |
563 | - renaming, reordering, moving, merging, and deleting categories; | |
564 | - sortable tabular summaries of categories and the types of items they contain; | |
adc5dbce | 565 | - cross-category lists of items filtered by specific criteria; |
d29bf51c SB |
566 | - more fine-grained interaction with the Emacs diary, by being able to decide |
567 | for each todo item whether it appears in the Fancy Diary display; | |
568 | - highly flexible new item insertion and item editing; | |
569 | - moving items between categories, storing done items in their category or in | |
570 | archive files, undoing or unarchiving done items; | |
571 | - reprioritizing items by inputting a numerical priority; | |
572 | - extensive customizability of operation and display, including numerous faces. | |
8bcced1f | 573 | The Todo mode user manual describes all commands and most user options. |
d29bf51c SB |
574 | To support some of these features, a new file format is used, which is |
575 | incompatible with the old format; however, you can convert old todo and done | |
576 | item files to the new format on initializing the first new todo file, or at any | |
577 | later time with the provided conversion command. The old version of | |
578 | todo-mode.el has been made obsolete and renamed otodo-mode.el. | |

770 | ** `visited-file-modtime' now returns -1 for nonexistent files. |

776 | incompatible change, but unless you are using interpreter-mode-alist | |
777 | for something (not just adding elements to it), it ought not to affect you. | |

857 | ** Support for filesystem notifications. |
858 | Emacs now supports notifications of filesystem changes, such as | |
859 | creation, modification, and deletion of files. This requires the | |
2f23b3ab MA |
860 | `glib' API, or the 'inotify' API (on GNU/Linux systems only). On |
861 | MS-Windows systems, this is supported for Windows XP and newer | |
862 | versions. | |

add89f61 MA |
864 | ** Changes in autorevert.el |
865 | ||
866 | --- | |
867 | *** If Emacs is compiled with file notification support, notifications | |
868 | are used instead of checking the time stamp of the files. You can | |
869 | disable this by setting the user option `auto-revert-use-notify' to | |
870 | nil. Alternatively, a regular expression of directories to be | |
871 | excluded from file notifications can be specified by | |
872 | `auto-revert-notify-exclude-dir-regexp'. | |
873 | ||
874 | --- | |

876 | of remote files when set to non-nil. | |

878 | ** Face changes |
879 | ||
02f473a4 | 880 | *** The function `face-spec-set' is now analogous to `setq' for face specs. |
1c4f115d CY |
881 | Its third arg now accepts values specifying exactly which face spec to |
882 | set (defface, custom, or user spec), and it directly sets the relevant | |
883 | property using the supplied face spec. | |
884 | ||
885 | *** Face specs set via Custom themes now replace the `defface' spec | |
886 | rather than inheriting from it (as do face specs set via Customize). | |
887 | ||
073ca75b JL |
888 | *** New face characteristic (supports :underline (:style wave)) |
889 | specifies whether or not the terminal can display a wavy line. | |
890 | ||
3c334c14 | 891 | *** New face spec attribute :distant-foreground |
920d0654 XF |
892 | specifies foreground to use if background color is near the foreground |
893 | color that would otherwise have been used. | |

f0c954fa GM |
895 | ** Image API |
896 | ||
897 | +++ | |
898 | *** `image-animated-p' is now `image-multi-frame-p'. | |
899 | It returns non-nil for any image that contains multiple frames, | |
900 | whether or not it specifies a frame delay. | |
901 | ||
902 | +++ | |
903 | *** When animating images that do not specify a frame delay, | |
904 | Emacs uses `image-default-frame-delay'. | |
905 | ||
906 | +++ | |
907 | *** New functions `image-current-frame' and `image-show-frame' for getting | |
908 | and setting the current frame of a multi-frame image. | |
909 | ||
3a2ddc2d GM |
910 | *** You can change the speed of animated images. |
911 | ||
1b796d6b EZ |
912 | ** Changes in encoding and decoding of text |
913 | ||
914 | --- | |
915 | *** New coding-system `prefer-utf-8'. | |
916 | This is like `undecided' but prefers UTF-8 on decoding if the text to | |
917 | be decoded does not contain any invalid UTF-8 sequences. On encoding, | |
918 | any non-ASCII characters are automatically encoded as UTF-8. | |
919 | ||
920 | --- | |
921 | *** New attributes of coding-systems whose type is `undecided'. | |
922 | Two new attributes, `:inhibit-null-byte-detection' and | |
923 | `:inhibit-iso-escape-detection', determine how to detect encoding of | |
924 | text that includes null bytes and ISO-2022 escape sequences, | |
925 | respectively. Each of these attributes can be either nil, zero, or | |
926 | t. If it is t, decoding text ignores null bytes and, respectively, | |
927 | ISO-2022 sequences. If it is nil, null bytes cause text to be decoded | |
928 | with no-conversion and ISO-2022 sequences cause Emacs to assume the | |
929 | text is encoded in one of the ISO-2022 encodings, such as | |
930 | iso-2022-7bit. If the value is zero, Emacs consults the variables | |
931 | inhibit-null-byte-detection and inhibit-iso-escape-detection, which | |
932 | see. | |
933 | The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer | |
934 | UTF-8 encoding and decoding, whenever possible. | |
935 | ||
936 | These attributes are only meaningful for coding-systems of type | |
937 | `undecided'. (The type of a coding-system is determined by its | |
938 | `:coding-type' attribute and can be accessed by calling the | |
939 | `coding-system-type' function.) | |
940 | ||
954b166e PE |
941 | ** The function `set-visited-file-modtime' now accepts a 0 or -1 argument |
942 | with the same interpretation as the returned value of `visited-file-modtime'. | |
943 | ||
855b17af | 944 | ** time-to-seconds is not obsolete any more. |
671d5c16 | 945 | ** New functions special-form-p and macrop. |
57618ecf SM |
946 | ** Docstrings can be made dynamic by adding a `dynamic-docstring-function' |
947 | text-property on the first char. | |
948 | ||
32e5c58c SM |
949 | ** The `defalias-fset-function' property lets you catch calls to defalias |
950 | and redirect them to your own function instead of `fset'. | |
951 | ||
70743157 | 952 | ** The lock for 'DIR/FILE' is now 'DIR/.#FILE' and may be a regular file. |
b5029e23 PE |
953 | When you edit DIR/FILE, Emacs normally creates a symbolic link |
954 | DIR/.#FILE as a lock that warns other instances of Emacs that DIR/FILE | |
955 | is being edited. Formerly, if there was already a non-symlink file | |
956 | named DIR/.#FILE, Emacs fell back on the lock names DIR/.#FILE.0 | |
957 | through DIR/.#FILE.9. These fallbacks have been removed, so that | |
958 | Emacs now no longer locks DIR/FILE in that case. | |
959 | ||
70743157 PE |
960 | On file systems that do not support symbolic links, the lock is now a |
961 | regular file with contents being what would have been in the symlink. | |
b5029e23 | 962 | |
97976f9f PE |
963 | ** The 9th element returned by `file-attributes' is now unspecified. |
964 | Formerly, it was t if the file's gid would change if file were deleted | |
965 | and recreated. This value has been inaccurate for years on many | |
966 | platforms, and nobody seems to have noticed or cared. | |
967 | ||
968 | ** The function `file-ownership-preserved-p' now has an optional | |
969 | argument GROUP which causes it check for file group too. This can be | |
970 | used in place of the 9th element of `file-attributes'. | |
971 | ||
972 | ** New functions `group-gid' and `group-real-gid'. | |
973 | ||
7c3d167f RF |
974 | ** The 6th argument to `copy-file' has been renamed to |
975 | `preserve-extended-attributes' as it now handles both SELinux context | |
976 | and ACL entries. | |
977 | ||
67982e2b SM |
978 | ** The `common-substring' argument of display-completion-list is obsolete. |
979 | Either use `completion-all-completions' which already returns highlighted | |
980 | strings (including for partial or substring completion) or call | |
981 | `completion-hilit-commonality' to add the highlight. | |
982 | ||
8fa2654e CS |
983 | ** Changes to the Emacs Lisp Coding Conventions in Emacs 24.4 |
984 | ||
985 | *** The package descriptor and name of global variables, constants, | |
0a2da075 | 986 | and functions should be separated by two hyphens if the symbol is not |
8fa2654e CS |
987 | meant to be used by other packages. |

95a32efb | 991 | |
7605d081 GM |
992 | ** The procedure for building Emacs on MS-Windows has changed. |
993 | It is now built by running the same configure script as on all other | |
994 | platforms. This requires the MSYS environment and MinGW development | |
995 | tools. See the updated instructions in nt/INSTALL for details. | |
671d4bfc GM |
996 | |
997 | Using the Posix configure script and Makefile's also means a change in | |
998 | the directory structure of the Emacs installation on Windows. It is | |
999 | now the same as on GNU and Unix systems. In particular, the auxiliary | |
1000 | programs, such as cmdproxy.exe and hexl.exe, are in | |
1001 | libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs | |
1002 | version), version-independent site-lisp is in share/emacs/site-lisp, | |
1003 | version-specific Lisp files are in share/emacs/VERSION/lisp and in | |
1004 | share/emacs/VERSION/site-lisp, Info docs are in share/info, and data | |
1005 | files are in share/emacs/VERSION/etc. (Emacs knows about all these | |
1006 | directories and will find the files in there automatically; there's no | |
1007 | need to set any variables due to this change.) | |
1008 | ||
7df14908 EZ |
1009 | +++ |
1010 | ** Emacs on Windows 2000 and later can now access files and directories | |
1011 | whose names cannot be encoded in the current system codepage. | |
1012 | ||
1013 | The new variable `w32-unicode-filenames' controls this feature: if it | |
1014 | is t, Emacs uses Unicode APIs to pass file names to system calls, | |
1015 | which lifts the limitation of file names to the current locale. | |
1016 | ||
5248293f GM |
1017 | +++ |
1018 | ** The "generate a backtrace on fatal error" feature now works on MS Windows. | |
1019 | The backtrace is written to the 'emacs_backtrace.txt' file in the | |
1020 | directory where Emacs was running. | |
1021 | ||
8549f9e8 EZ |
1022 | +++ |
1023 | ** The variable `buffer-file-type' is no longer supported. | |
1024 | Setting it has no effect, and %t in the mode-line format is ignored. | |
1025 | Likewise, `file-name-buffer-file-type-alist' is now obsolete, and | |
1026 | modifying it has no effect. | |
1027 | ||
343a2aef EZ |
1028 | --- |
1029 | ** Lock files now work on MS-Windows. | |
1030 | This allows to avoid losing your edits if the same file is being | |
1031 | edited in another Emacs session or by another user. See the node | |
1032 | "Interlocking" in the Emacs User Manual for the details. To disable | |
1033 | file locking, customize `create-lockfiles' to nil. | |
1034 | ||
c57b2d76 GM |
1035 | ** Improved fullscreen support on Mac OS X. |
1036 | Both native (>= OSX 10.7) and "old style" fullscreen are supported. | |
1037 | Customize `ns-use-native-fullscreen' to change style. For >= 10.7 | |
1038 | native is the default. | |

b8df54ff | 1042 | |
6bc66c10 | 1043 | ** The default X toolkit is now Gtk+ version 3. |
823b2fb6 GM |
1044 | If you don't pass `--with-x-toolkit' to configure, or if you use |
1045 | `--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try | |
1046 | to build with Gtk+ version 3, and if that fails, try Gtk+ version 2. | |
d71a6517 | 1047 | You can explicitly require a specific version by passing |
823b2fb6 | 1048 | `--with-x-toolkit=gtk2' or `--with-x-toolkit=gtk3' to configure. |
da3d2105 | 1049 | |
6bc66c10 | 1050 | ** New configure option `--enable-link-time-optimization', to utilize |
da3d2105 DA |
1051 | an appropriate feature provided by GCC since version 4.5.0. |
1052 | ||
33cb2043 GM |
1053 | ** New configure option `--without-all' to disable most of the optional |
1054 | features (image support, etc.) that are normally enabled by default. | |
b8df54ff | 1055 | |
33cb2043 GM |
1056 | ** New configure option `--enable-gcc-warnings' (for developing/debugging |
1057 | Emacs). If building with GCC, this enables compile-time checks that | |
64420fcd GM |
1058 | warn/give errors about possibly-questionable C code. On a recent GNU |
1059 | system there should be no warnings; on older and on non-GNU systems | |
1060 | the results may be useful to developers. | |
b8df54ff | 1061 | |
823b2fb6 | 1062 | ** The configure option `--enable-use-lisp-union-type' has been |
6bc66c10 | 1063 | renamed to `--enable-check-lisp-object-type', as the resulting |
d71a6517 GM |
1064 | Lisp_Object type no longer uses a union to implement the compile time |
1065 | check that this option enables. | |
1066 | ||
823b2fb6 | 1067 | ** The configure option `--disable-maintainer-mode' has been removed, |
501390c5 PE |
1068 | as it was confusingly-named and rarely useful. |
1069 | ||
f14a4380 GM |
1070 | ** The configure options `--program-prefix', `--program-suffix', and |
1071 | `--program-transform-name' apply to more than just the installed | |
1072 | binaries. Now they also affect the man pages, icons, and the | |
1073 | etc/emacs.desktop file; but not the info pages, since this would break | |
1074 | links between the various manuals. | |
1a9c6830 | 1075 | |
823b2fb6 GM |
1076 | ** You can use `NO_BIN_LINK=t make install' to prevent the installation |

a4a18b8b GM |
1080 | ** Emacs uses libtinfo in preference to libncurses, if available. |

187e9b90 GM |
1082 | ** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and |

6bc66c10 | 1104 | *** `C-h f' (`describe-function') can now perform autoloading. |
c89926a5 CY |
1105 | When this command is called for an autoloaded function whose docstring |
1106 | contains a key substitution construct, that function's library is | |
1107 | automatically loaded, so that the documentation can be shown | |

1134 | keywords. | |
1135 | ||
8259030d | 1136 | *** Some data types aren't auto-detected by ImageMagick. Adding |

1140 | ** Minibuffer |
1141 | ||
1142 | *** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the | |
1143 | next and previous path separator, respectively. | |
c505aaeb | 1144 | |
6bc66c10 GM |
1145 | *** `minibuffer-electric-default-mode' can shorten "(default ...)" to "[...]" |
1146 | in minibuffer prompts. Just set `minibuffer-eldef-shorten-default' | |
1147 | non-nil before enabling the mode. | |
1148 | ||
1149 | ** Mode line | |
1150 | ||
1151 | *** New option `mode-line-default-help-echo' specifies the help text | |
1152 | (shown in a tooltip or in the echo area) for any part of the mode line | |
1153 | that does not have its own specialized help text. | |
1154 | ||
1155 | *** You can now click mouse-3 in the coding system indicator to invoke | |
1156 | `set-buffer-file-coding-system'. | |

2f940384 | 1159 | |
f938eda9 CY |
1160 | *** emacsclient now obeys string values for `initial-buffer-choice', |

1162 | or expression to evaluate. | |
db80bdc8 | 1163 | |
f938eda9 | 1164 | *** New option `server-auth-key' specifies a shared server key. |
f938eda9 CY |
1165 | |
1166 | ** Emacs now generates backtraces on fatal errors. | |
1167 | On encountering a fatal error, Emacs now outputs a textual description | |
1168 | of the fatal signal, and a short backtrace on platforms like glibc | |
5248293f | 1169 | that support backtraces. |
2e2d2a13 | 1170 | |
6bc66c10 GM |
1171 | ** `C-x C-q' is now bound to the new minor mode `read-only-mode'. |
1172 | This minor mode replaces `toggle-read-only', which is now obsolete. | |
1173 | ||
1174 | ** Most `y-or-n' prompts now allow you to scroll the selected window. | |
1175 | Typing `C-v' or `M-v' at a y-or-n prompt scrolls forward or backward | |
1176 | respectively, without exiting from the prompt. | |
1177 | ||
1178 | ** In the Package Menu, newly-available packages are listed as "new", | |
1179 | and sorted above the other "available" packages by default. | |

1181 | ** If your Emacs was built from a bzr checkout, the new variable |
1182 | `emacs-bzr-version' contains information about the bzr revision used. | |
de6ff46d | 1183 | |
6bc66c10 | 1184 | ** New option `create-lockfiles' specifies usage of lockfiles. |
f938eda9 CY |
1185 | It defaults to t. Changing it to nil inhibits the creation of lock |
1186 | files (use this with caution). | |
dc0f75c8 | 1187 | |
6bc66c10 GM |
1188 | ** New option `enable-remote-dir-locals', if non-nil, allows directory-local |

1198 | has been changed to `C-c M-i' (`report-emacs-bug-insert-to-mailer'). | |
1199 | The previous binding, introduced in Emacs 24.1, was a mistake, because | |
1200 | `C-c LETTER' bindings are reserved for user customizations. | |
1201 | ||
6bc66c10 | 1202 | ** Internationalization |
2f940384 | 1203 | |

6bc66c10 | 1218 | ** Search and Replace |
d39d3c8e | 1219 | |
f938eda9 CY |
1220 | *** Non-regexp Isearch now performs "lax" space matching. |
1221 | Each sequence of spaces in the supplied search string may match any | |
1222 | sequence of one or more whitespace characters, as specified by the | |
1223 | variable `search-whitespace-regexp'. (This variable is also used by a | |
823b2fb6 | 1224 | similar existing feature for regexp Isearch.) |
2f940384 | 1225 | |
f938eda9 CY |
1226 | *** New Isearch command `M-s SPC' toggles lax space matching. |
1227 | This applies to both ordinary and regexp Isearch. | |
2f940384 | 1228 | |
f938eda9 CY |
1229 | *** New option `replace-lax-whitespace'. |
1230 | If non-nil, `query-replace' uses flexible whitespace matching too. | |
1231 | The default is nil. | |
2f940384 | 1232 | |
b9cb2387 JL |
1233 | *** Global `M-s _' starts a symbol (identifier) incremental search, |
1234 | and `M-s _' in Isearch toggles symbol search mode. | |
1235 | `M-s c' in Isearch toggles search case-sensitivity. | |
1236 | ||
6bc66c10 | 1237 | ** Navigation commands |
48de8b12 | 1238 | |
6bc66c10 GM |
1239 | *** New binding `M-g c' for `goto-char'. |
1240 | ||
1241 | *** New binding `M-g TAB' for `move-to-column'. | |
1242 | ||
1243 | *** `M-g TAB' (`move-to-column') prompts for a column number if called | |
1244 | interactively with no prefix arg. Previously, it moved to column 1. | |
1245 | ||
1246 | ** New option `yank-handled-properties' allows processing of text | |
1247 | properties on yanked text, in ways that are more general than just | |
1248 | removing them (as is done by `yank-excluded-properties'). | |
48de8b12 | 1249 | |
48de8b12 CY |
1250 | ** New option `delete-trailing-lines' specifies whether |
1251 | M-x delete-trailing-whitespace should delete trailing lines at the end | |
1252 | of the buffer. It defaults to t. | |
1253 | ||
f938eda9 | 1254 | ** `C-u M-=' now counts lines/words/characters in the entire buffer. |
826b3235 | 1255 | |
48de8b12 CY |
1256 | ** `C-x 8 RET' is now bound to `insert-char', which is now a command. |
1257 | `ucs-insert' is now an obsolete alias for `insert-char'. | |
b2459884 | 1258 | |
48de8b12 CY |
1259 | ** The `z' key no longer has a binding in most special modes. |
1260 | It used to be bound to `kill-this-buffer', but `z' is too easy to | |
1261 | accidentally type. | |
f938eda9 | 1262 | |
6bc66c10 GM |
1263 | ** New command `C-x r M-w' (`copy-rectangle-as-kill'). |
1264 | It copies the region-rectangle as the last rectangle kill. | |
f938eda9 | 1265 | |
6bc66c10 | 1266 | ** Registers |
f938eda9 | 1267 | |

f938eda9 | 1269 | |
f938eda9 | 1270 | *** New option `register-separator' specifies the register containing |
823b2fb6 GM |
1271 | the text to put between collected texts for use with |
1272 | M-x append-to-register and M-x prepend-to-register. | |

ae4969c2 | 1276 | |
6bc66c10 | 1277 | ** Common Lisp emulation (CL) |
f938eda9 | 1278 | |
89660017 | 1279 | *** CL's main entry is now (require 'cl-lib). |
823b2fb6 GM |
1280 | `cl-lib' is like the old `cl' except that it uses the namespace cleanly; |
1281 | i.e., all its definitions have the "cl-" prefix (and internal definitions | |
1282 | use the "cl--" prefix). | |
7c1898a7 | 1283 | |
823b2fb6 GM |
1284 | If `cl' provided a feature under the name `foo', then `cl-lib' |
1285 | provides it under the name `cl-foo' instead; with the exceptions of the | |
1286 | few `cl' definitions that had to use `foo*' to avoid conflicts with | |
1287 | pre-existing Elisp entities. These have been renamed to `cl-foo' | |
1288 | rather than `cl-foo*'. | |
7c1898a7 | 1289 | |
92246540 | 1290 | The old `cl' is now deprecated and is mainly just a bunch of aliases that |
823b2fb6 | 1291 | provide the old, non-prefixed names. Some exceptions are listed below: |
7c1898a7 | 1292 | |
89660017 SM |
1293 | *** `cl-flet' is not like `flet' (which is deprecated). |
1294 | Instead it obeys the behavior of Common-Lisp's `flet'. | |
e8693c96 GM |
1295 | In particular, in cl-flet function definitions are lexically scoped, |
1296 | whereas in flet the scoping is dynamic. | |
89660017 SM |
1297 | |
1298 | *** `cl-labels' is slightly different from `labels'. | |
823b2fb6 GM |
1299 | The difference is that it relies on the `lexical-binding' machinery |
1300 | (as opposed to the `lexical-let' machinery used previously) to capture | |
1301 | definitions in closures, so such closures will only work if `lexical-binding' | |
1302 | is in use. | |
89660017 | 1303 | |
f94b04fc | 1304 | *** `cl-letf' is not exactly like `letf'. |
4ddedf94 GM |
1305 | The only difference is in details that relate to some deprecated usage |
1306 | of `symbol-function' in place forms. | |
f94b04fc | 1307 | |
89660017 | 1308 | *** `progv' was rewritten to use the `let' machinery. |
823b2fb6 GM |
1309 | A side effect is that variables without corresponding values are bound |
1310 | to nil rather than being made unbound. | |
89660017 | 1311 | |
9512f820 GM |
1312 | *** The following methods of extending `setf' are obsolete |
1313 | (use features from gv.el instead): | |
1314 | `define-modify-macro' (use `gv-letplace') | |
031b2ea7 GM |
1315 | `defsetf' (use `gv-define-simple-setter' or `gv-define-setter') |
1316 | `define-setf-expander' (use `gv-define-setter' or `gv-define-expander') | |
2b4da3ff | 1317 | `get-setf-method' no longer exists (see "Incompatible Lisp Changes") |
f94b04fc | 1318 | |
6bc66c10 | 1319 | ** Diff mode |
f938eda9 | 1320 | |
6bc66c10 GM |
1321 | *** Changes are now highlighted using the same color scheme as in |
1322 | modern VCSes. Deletions are displayed in red (new faces | |
1323 | `diff-refine-removed' and `smerge-refined-removed', and new definition | |
1324 | of `diff-removed'), insertions in green (new faces `diff-refine-added' | |
1325 | and `smerge-refined-added', and new definition of `diff-added'). | |
f938eda9 | 1326 | |
6bc66c10 GM |
1327 | *** The variable `diff-use-changed-face' defines whether to use the |
1328 | face `diff-changed', or `diff-removed' and `diff-added' to highlight | |
1329 | changes in context diffs. | |
2f940384 | 1330 | |
6bc66c10 GM |
1331 | *** The new command `diff-delete-trailing-whitespace' removes trailing |
1332 | whitespace introduced by a diff. | |
f938eda9 | 1333 | |
6bc66c10 GM |
1334 | ** Ediff now uses the same color scheme as Diff mode. |
1335 | ||
1336 | ** Python mode | |
1337 | ||
1338 | A new version of python.el, which provides several new features, including: | |
1339 | per-buffer shells, better indentation, Python 3 support, and improved | |
1340 | shell-interaction compatible with iPython (and virtually any other | |
1341 | text based shell). | |
1342 | ||
1343 | *** Some user options have been replaced/renamed, including (old -> new): | |
1344 | **** python-indent -> python-indent-offset | |

d5b1b1aa | 1354 | Comments are always considered as indentation markers. |
6bc66c10 GM |
1355 | |
1356 | **** `python-continuation-offset': Indentation is automatically | |
1357 | calculated in a pep8 compliant way depending on the context. | |
1358 | ||
1359 | **** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist': | |
1360 | Have no direct mapping as the shell interaction is completely different. | |
1361 | ||
1362 | **** `python-python-command', `python-jython-command': | |
1363 | Replaced by `python-shell-interpreter'. | |
1364 | ||
1365 | **** `inferior-python-filter-regexp', `python-remove-cwd-from-path', | |
1366 | `python-pdbtrack-minor-mode-string', `python-source-modes': | |
1367 | No longer relevant. | |

2f940384 | 1416 | |
f938eda9 CY |
1417 | *** `dired-do-async-shell-command' executes each file sequentially |

1419 | Otherwise, it executes the command on each file in parallel. | |
2f940384 | 1420 | |
823b2fb6 GM |
1421 | *** Typing `M-n' in the minibuffer of `dired-do-chmod', `dired-do-chgrp', |
1422 | `dired-do-chown', and `dired-do-touch' yanks the attributes of the | |
f938eda9 | 1423 | file at point. |
2f940384 | 1424 | |
f938eda9 | 1425 | *** When the region is active, `m' (`dired-mark'), `u' (`dired-unmark'), |
823b2fb6 | 1426 | `DEL' (`dired-unmark-backward'), and `d' (`dired-flag-file-deletion') |

2f940384 | 1428 | |
88c45e34 | 1429 | *** The minibuffer default for `=' (`dired-diff') has changed. |
f938eda9 CY |
1430 | It is now the backup file for the file at point, if one exists. |
1431 | In Transient Mark mode the default is the file at the active mark. | |

1482 | **** `ruby-beginning-of-defun' and `ruby-end-of-defun' are replaced by | |
1483 | appropriate settings for the variables `beginning-of-defun-function' | |
1484 | and `end-of-defun-function'. | |
1485 | ||
1486 | **** Non-standard keybindings for `backward-kill-word', `comment-region', | |
1487 | `reindent-then-newline-and-indent' and `newline' have been removed. | |
1488 | ||
6bc66c10 | 1489 | ** Shell Script mode |
40d8bcb8 | 1490 | |
6bc66c10 | 1491 | *** Pairing of parens/quotes uses `electric-pair-mode' instead of skeleton-pair. |
40d8bcb8 | 1492 | |
6bc66c10 | 1493 | *** `sh-electric-here-document-mode' now controls auto-insertion of here-docs. |
40d8bcb8 | 1494 | |
6bc66c10 | 1495 | *** `sh-use-smie' lets you choose a new indentation and navigation code. |
40d8bcb8 | 1496 | |
6bc66c10 | 1497 | ** VHDL mode |
40d8bcb8 | 1498 | |
6bc66c10 | 1499 | *** The free software compiler GHDL is supported (and now the default). |
40d8bcb8 | 1500 | |
6bc66c10 | 1501 | *** Support for the VHDL-AMS packages has been added/updated. |
40d8bcb8 | 1502 | |
6bc66c10 | 1503 | *** Updated to the 2002 revision of the VHDL standard. |
40d8bcb8 | 1504 | |
6bc66c10 | 1505 | *** Accepts \r and \f as whitespace. |
40d8bcb8 | 1506 | |
6bc66c10 | 1507 | ** Apropos |
40d8bcb8 | 1508 | |
6bc66c10 GM |
1509 | *** The faces used by Apropos are now directly customizable. |
1510 | These faces are named `apropos-symbol', `apropos-keybinding', and so on; | |
1511 | see the `apropos' Custom group for details. | |
d13c8be6 | 1512 | |
6bc66c10 GM |
1513 | *** The old options whose values specified faces to use have been removed |
1514 | (i.e. `apropos-symbol-face', `apropos-keybinding-face', etc.). | |
d13c8be6 | 1515 | |
6bc66c10 | 1516 | ** Buffer Menu |
d13c8be6 | 1517 | |
6bc66c10 | 1518 | *** This package has been rewritten to use Tabulated List mode. |
d13c8be6 | 1519 | |
6bc66c10 GM |
1520 | *** Option `Buffer-menu-buffer+size-width' is now obsolete. |
1521 | Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead. | |
d13c8be6 | 1522 | |
86e100a6 GM |
1523 | ** Calc |
1524 | ||
1525 | *** Algebraic simplification mode is now the default. | |
1526 | To restrict to the limited simplifications given by the former | |
1527 | default simplification mode, use `m I'. | |
1528 | ||
6bc66c10 | 1529 | ** Calendar |
d13c8be6 | 1530 | |
6bc66c10 GM |
1531 | *** You can customize the header text that appears above each calendar month. |
1532 | See the variable `calendar-month-header'. | |
d13c8be6 | 1533 | |
6bc66c10 | 1534 | *** New LaTeX calendar style, produced by `cal-tex-cursor-week2-summary'. |
ee97deee | 1535 | |
6bc66c10 GM |
1536 | *** The calendars produced by cal-html include holidays. |
1537 | Customize `cal-html-holidays' to change this. | |
8b0823d6 | 1538 | |
0058cae2 GM |
1539 | ** CEDET |
1540 | ||
1541 | *** The major modes from the parser generators "Bovine" and "Wisent" | |
1542 | are now properly integrated in Emacs. The file suffixes ".by" and ".wy" | |
1543 | are in `auto-mode-alist', and the corresponding manuals are included. | |
1544 | ||
1545 | *** EDE | |
1546 | ||
1547 | **** Menu support for the "Configuration" feature. This allows users to | |
1548 | choose the active configuration (such as debug or install) from the menu. | |
1549 | ||
1550 | **** New command `ede-set' to interactively set project-local variables. | |
1551 | ||
1552 | **** Support for compiling, debugging, and running in "generic" projects. | |
1553 | ||

1563 | ||
1564 | **** Improved support for 'extern "C"' declarations in C/C++. | |
1565 | ||
1566 | **** The ability to ignore more common special C/C++ preprocessor symbols, | |
1567 | such as '__nonnull' and '__asm'. Add '__cplusplus' macro when parsing C++. | |
1568 | If available, include cdefs.h as an additional source of preprocessor symbols. | |
1569 | ||
1570 | **** Improved C/C++ function pointer parsing. | |
1571 | ||
1572 | **** In Python, support for converting imports to include file names. | |
1573 | ||
1574 | **** Ability to dynamically determine the Python load path. | |
1575 | ||
1576 | **** Support for the Python 'WITH' and 'AT' keywords. | |
1577 | ||
1578 | **** Improved tooltip completion. | |
1579 | ||
1580 | *** SRecode | |
1581 | ||
1582 | **** The SRecode manual is now included. | |
1583 | ||
1584 | **** Tag generation supports constructor/destructor settings and system | |
1585 | include differentiation. | |
1586 | ||
1587 | **** Addition of 'Framework' support: Frameworks are specified when a | |
1588 | particular kind of library (such as Android) is needed in a common language | |
1589 | mode (like Java). | |
1590 | ||
1591 | **** Support for nested templates and let variables override based on priority. | |
1592 | ||
1593 | **** Support for merging tables from multiple related modes, such as | |
1594 | default -> c++ -> arduino. | |

6bc66c10 | 1596 | ** Compile has a new option `compilation-always-kill'. |
42917e79 | 1597 | |
6bc66c10 | 1598 | ** Customize |
35d98877 | 1599 | |
6bc66c10 | 1600 | *** `custom-reset-button-menu' now defaults to t. |
35d98877 | 1601 | |
6bc66c10 GM |
1602 | *** Non-option variables are never matched in `customize-apropos' and |
1603 | `customize-apropos-options' (i.e., the prefix argument does nothing for | |
1604 | these commands now). | |
782fbf2a | 1605 | |
f938eda9 | 1606 | ** Term |
782fbf2a | 1607 | |
823b2fb6 GM |
1608 | *** The variables `term-default-fg-color' and `term-default-bg-color' |
1609 | are now deprecated in favor of the customizable face `term'. | |
fc72b15c | 1610 | |
02969baf GM |
1611 | *** You can customize how to display ANSI terminal colors and styles |
1612 | by customizing the corresponding `term-color-<COLOR>', | |
1613 | `term-color-underline' and `term-color-bold' faces. | |
cf20dee0 | 1614 | |
05ecb497 | 1615 | ** Tramp |
2f940384 | 1616 | |
02969baf | 1617 | *** The syntax has been extended in order to allow ad-hoc proxy definitions. |

05ecb497 | 1620 | |
ce7b18ec | 1621 | ** URL |
2f940384 | 1622 | |
ce7b18ec CY |
1623 | *** Structs made by `url-generic-parse-url' have nil `attributes' slot. |
1624 | Previously, this slot stored semicolon-separated attribute-value pairs | |
1625 | appended to some imap URLs, but this is not compatible with RFC 3986. | |
823b2fb6 | 1626 | So now the `filename' slot stores the entire path and query components, |
ce7b18ec | 1627 | and the `attributes' slot is always nil. |
2f940384 | 1628 | |
ce7b18ec CY |
1629 | *** New function `url-encode-url' for encoding a URI string. |
1630 | The `url-retrieve' function now uses this to encode its URL argument, | |
1631 | in case that is not properly encoded. | |
1632 | ||
843571cb LMI |
1633 | *** New command `url-cookie-list' displays all the current cookies, and |
1634 | allows deleting selected cookies. | |
1635 | ||
6bc66c10 GM |
1636 | ** notifications.el supports now version 1.2 of the Notifications API. |
1637 | The function `notifications-get-capabilities' returns the supported | |
1638 | server properties. | |
f938eda9 | 1639 | |
6bc66c10 GM |
1640 | ** Flymake uses fringe bitmaps to indicate errors and warnings. |
1641 | See `flymake-fringe-indicator-position', `flymake-error-bitmap' and | |
1642 | `flymake-warning-bitmap'. | |
f938eda9 | 1643 | |
6bc66c10 GM |
1644 | ** The FFAP option `ffap-url-unwrap-remote' can now be a list of strings, |
1645 | specifying URL types that should be converted to remote file names at | |
1646 | the FFAP prompt. The default is now '("ftp"). | |
f938eda9 | 1647 | |
6bc66c10 GM |
1648 | ** New Ibuffer `derived-mode' filter, bound to `/ M'. |
1649 | The old binding for `/ M' (filter by used-mode) is now bound to `/ m'. | |
f938eda9 | 1650 | |
6bc66c10 GM |
1651 | ** New option `mouse-avoidance-banish-position' specifies where the |
1652 | `banish' mouse avoidance setting moves the mouse. | |
ce7b18ec | 1653 | |
6bc66c10 GM |
1654 | ** In Perl mode, new option `perl-indent-parens-as-block' causes non-block |
1655 | closing brackets to be aligned with the line of the opening bracket. | |
f938eda9 | 1656 | |
6bc66c10 | 1657 | ** In Proced mode, new command `proced-renice' renices marked processes. |
f938eda9 | 1658 | |
6bc66c10 GM |
1659 | ** New option `async-shell-command-buffer' specifies the buffer to use |
1660 | for a new asynchronous `shell-command' when the default output buffer | |
1661 | `*Async Shell Command*' is already in use. | |
f938eda9 | 1662 | |
6bc66c10 GM |
1663 | ** SQL mode has a new option `sql-db2-escape-newlines'. |
1664 | If non-nil, newlines sent to the command interpreter will be escaped | |
1665 | by a backslash. The default does not escape the newlines and assumes | |
1666 | that the sql statement will be terminated by a semicolon. | |
f938eda9 | 1667 | |
6bc66c10 GM |
1668 | ** New command `tabulated-list-sort', bound to `S' in Tabulated List mode |
1669 | (and modes that derive from it), sorts the column at point, or the Nth | |
1670 | column if a numeric prefix argument is given. | |
f938eda9 | 1671 | |
02969baf | 1672 | ** `which-func-modes' now defaults to t, so Which Function mode, when |
05b621a6 | 1673 | enabled, applies to all applicable major modes. |
f938eda9 | 1674 | |
6bc66c10 | 1675 | ** `winner-mode-hook' now runs when the mode is disabled, as well as when |
823b2fb6 | 1676 | it is enabled. |
f938eda9 | 1677 | |
6bc66c10 GM |
1678 | ** Follow mode no longer works by using advice. |
1679 | The option `follow-intercept-processes' has been removed. | |
1680 | ||
1681 | ** `javascript-generic-mode' is now an obsolete alias for `js-mode'. | |
f938eda9 | 1682 | |

6bc66c10 | 1707 | ** Obsolete packages |
2f940384 | 1708 | |
797e6e88 SM |
1709 | *** assoc.el |
1710 | In most cases, assoc+member+push+delq work just as well. | |
1711 | And in any case it's just a terrible package: ugly semantics, terrible | |
1712 | inefficiency, and not namespace-clean. | |

b4d3bc10 | 1722 | |
6bc66c10 GM |
1723 | ** Docstrings starting with `*' no longer indicate user options. |
1724 | Only variables defined using `defcustom' are considered user options. | |
1725 | The function `user-variable-p' is now an obsolete alias for | |
1726 | `custom-variable-p'. | |
090cf9db | 1727 | |
6bc66c10 GM |
1728 | ** The return values of `defalias', `defun' and `defmacro' have changed, |
1729 | and are now undefined. For backwards compatibility, `defun' and | |
1730 | `defmacro' currently return the name of the newly defined | |
1731 | function/macro, but this should not be relied upon. | |
090cf9db | 1732 | |
823b2fb6 GM |
1733 | ** `random' by default now returns a different random sequence in |
1734 | every Emacs run. Use `(random S)', where S is a string, to set the | |
0e23ef9d PE |
1735 | random seed to a value based on S, in order to get a repeatable |
1736 | sequence in later calls. | |
1737 | ||
d32e47af LM |
1738 | ** If the NEWTEXT arg to `replace-match' contains a substring "\?", |
1739 | that substring is inserted literally even if the LITERAL arg is | |
1740 | non-nil, instead of causing an error to be signaled. | |
1741 | ||
2cec368c MR |
1742 | ** `select-window' now always makes the window's buffer current. |
1743 | It does so even if the window was selected before. | |
1744 | ||
6bc66c10 GM |
1745 | ** The function `x-select-font' can return a font spec, instead of a |
1746 | font name as a string. Whether it returns a font spec or a font name | |
1747 | depends on the graphical library. | |
bbf908bc | 1748 | |
eeddc531 CY |
1749 | ** `face-spec-set' no longer sets frame-specific attributes when the |
1750 | third argument is a frame (that usage was obsolete since Emacs 22.2). | |
1751 | ||
6bc66c10 | 1752 | ** `set-buffer-multibyte' now signals an error in narrowed buffers. |
a59d531e | 1753 | |
ab7f1c43 GM |
1754 | ** The CL package's `get-setf-method' function no longer exists. |
1755 | Generalized variables are now part of core Emacs Lisp, and implemented | |
1756 | differently to the way cl.el used to do it. It is not possible to | |
1757 | define a compatible replacement for `get-setf-method'. See the file | |
1758 | gv.el for internal details of the new implementation. | |
1759 | ||
6bc66c10 GM |
1760 | ** The arguments of `dbus-register-signal' are no longer just strings, |
1761 | but keywords or keyword-string pairs. The old argument list will | |
1762 | still be supported for Emacs 24.x. | |
72b255c7 | 1763 | |
6bc66c10 | 1764 | ** Miscellaneous name changes |
823b2fb6 GM |
1765 | Some Lisp symbols have been renamed to correct their spelling, |
1766 | or to be more consistent with standard Emacs terminology. | |
72b255c7 | 1767 | |
72b255c7 | 1768 | *** Renamed functions |

ef24141c | 1813 | |
2ee3d7f0 | 1814 | ** CL-style generalized variables are now in core Elisp. |
f938eda9 | 1815 | `setf' is autoloaded; `push' and `pop' accept generalized variables. |
ebdbfb95 GM |
1816 | You can define your own generalized variables using `gv-define-simple-setter', |
1817 | `gv-define-setter', etc. | |
2ee3d7f0 | 1818 | |
6bc66c10 GM |
1819 | ** Emacs tries to macroexpand interpreted (non-compiled) files during load. |
1820 | This can significantly speed up execution of non-byte-compiled code, | |
1821 | but can also bump into previously unnoticed cyclic dependencies. | |
1822 | These are generally harmless: they will simply cause the macro calls | |
1823 | to be left for later expansion (as before), but will result in a | |
1824 | warning ("Eager macro-expansion skipped due to cycle") describing the cycle. | |
1825 | You may wish to restructure your code so this does not happen. | |
1826 | ||
1827 | ** New sampling-based Elisp profiler. | |
1828 | Try M-x profiler-start, do some work, and then call M-x profiler-report. | |
1829 | When finished, use M-x profiler-stop. The sampling rate can be based on | |
1830 | CPU time or memory allocations. | |
1831 | ||

823b2fb6 GM |
1933 | functions that use this format, such as `file-attributes' and |

1950 | the class to load, as well as a flag stating whether subclasses are allowed; | |
1951 | if provided, other classes will be rejected by the reader. For | |
1952 | compatibility with existing code, if the class is omitted only a | |
1953 | warning is issued. | |
1954 | ||
1955 | **** New specialized reader for pulling in classes and signaling errors | |
1956 | without evaluation of suspicious code. | |

6e9f7997 DC |
2017 | `cygwin-convert-file-name-from-windows' and |
2018 | `cygwin-convert-file-name-to-windows'. These functions allow Lisp | |
2019 | code to access the Cygwin file-name mapping machinery to convert | |
2020 | between Cygwin and Windows-native file and directory names. | |

2024 | `mouse-autoselect-window'. |
2025 | ||
1a9c6830 | 2026 | ** On MS Windows Vista and later Emacs now supports symbolic links. |
4e98ad15 | 2027 | |
823b2fb6 | 2028 | ** On MS Windows, you can pass `--without-libxml2' to configure.bat to omit |
4e98ad15 GM |
2029 | support for libxml2, even if its presence is detected. |
2030 | ||
4e98ad15 GM |
2031 | ** On Mac OS X, the Nextstep port requires OS X 10.4 or later. |

31fd3586 GM |
2044 | ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
2045 | to configure. Note that other libraries used by Emacs, RSVG and GConf, | |
2046 | also depend on Gtk+. You can disable them with --without-rsvg and | |
2047 | --without-gconf. | |
338648ad | 2048 | |
31fd3586 GM |
2049 | ** Emacs can be compiled with GnuTLS support. |
2050 | This happens by default if a suitably recent version of the library is | |
2051 | found at build time. To prevent this, use the configure option | |
2052 | `--without-gnutls'. See below for GnuTLS features. | |
338648ad | 2053 | |
31fd3586 GM |
2054 | ** Emacs can be compiled with SELinux support. |

2059 | ** Emacs can be compiled with ImageMagick support. |
2060 | This happens by default if a suitably recent version of the library is | |
2061 | found at build time. To prevent this, use the configure option | |
2062 | `--without-imagemagick'. See below for ImageMagick features. | |

7d301ae6 CY |
2070 | ** By default, the installed Info and man pages are compressed. |
2071 | You can disable this by configuring --without-compress-info. | |
2072 | ||
7d301ae6 | 2073 | ** New configure option --with-wide-int. |
81eafe29 | 2074 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. |
0a768890 PE |
2075 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB |
2076 | to about 2 GiB. | |
81eafe29 | 2077 | |
7d301ae6 | 2078 | ** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost. |
31fd3586 GM |
2079 | These provide no new functionality, they just remove the need to edit |
2080 | lib-src/Makefile by hand in order to use the associated features. | |
2081 | ||
7d301ae6 | 2082 | ** New configure option --enable-use-lisp-union-type. |
31fd3586 GM |
2083 | This is only useful for Emacs developers to debug certain types of bugs. |
2084 | This is not a new feature; only the configure flag is new. | |
041d709f CY |
2085 | |
2086 | ** The standalone programs digest-doc and sorted-doc are removed. | |

66b7b0fe | 2099 | ** New command line option `--no-site-lisp' removes site-lisp directories |
1b5e5b0c GM |
2100 | from load-path. -Q now implies this. This option does not affect the |

2110 | rather than implementing separate completion commands. | |
2111 | ||
de0bde62 | 2112 | *** `completion-at-point' now handles tags and semantic completion. |
dfdb4cad | 2113 | |
a2a25d24 SM |

2115 | and pops down the *Completions* buffer accordingly. | |
dfdb4cad CY |
2116 | |
2117 | *** New option `completion-cycle-threshold' allows completion cycling. | |

2c719188 | 2120 | default completion style in certain circumstances. |
dfdb4cad | 2121 | |
a2a25d24 | 2122 | *** New completion style `substring'. |
dfdb4cad CY |

6870aaef | 2128 | ** Mail changes |
dfdb4cad | 2129 | |
7d301ae6 CY |
2130 | *** The first time you try sending mail, Emacs asks for a mail method. |
2131 | This is implemented by a new default for `send-mail-function', which | |
2132 | is `sendmail-query-once'. This offers to use the smtpmail package, or | |
2133 | to use the old defaults relying on external mail facilities | |
2134 | (`sendmail-send-it' on GNU/Linux and other Unix-like systems, and | |
2135 | `mailclient-send-it' on Windows). | |
dfdb4cad | 2136 | |
e78e7e48 CY |
2137 | *** Typing `C-c m' in the buffer made by `M-x report-emacs-bug' |
2138 | transfers the report to your desktop's preferred mail client, if there | |
2139 | is one. This uses either the "xdg-email" utility, or Mac OS's "open" | |
2140 | command. | |

dfdb4cad | 2150 | |
7d301ae6 CY |
2151 | *** New emacsclient argument --frame-parameters specifies the frame |
2152 | parameters of any newly-created graphical frame. | |
dfdb4cad CY |
2153 | |
2154 | *** If emacsclient shuts down due to Emacs signaling an error, | |
2155 | its exit status is 1. | |
2156 | ||
041d709f CY |
2157 | *** New emacsclient argument --parent-id ID. |
2158 | This opens a client frame in parent X window ID, via XEmbed, similar | |
2159 | to the --parent-id argument to Emacs. | |

2164 | Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are |
2165 | displayed in the correct visual order as expected by users of those | |
dfdb4cad CY |
2166 | scripts. The display reordering is a "full bidirectionality" class |
2167 | implementation of the Unicode Bidirectional Algorithm (UBA). Buffers | |
2168 | with no RTL text should look exactly the same as before. | |
f4b6ba46 | 2169 | |
041d709f | 2170 | **** New buffer-local variable `bidi-display-reordering'. |
7d301ae6 | 2171 | To disable display reordering in a buffer, change this to nil. |

041d709f CY |
2173 | **** New buffer-local variable `bidi-paragraph-direction'. |
2174 | If nil (the default), Emacs determines the base direction of each | |
dfdb4cad CY |
2175 | paragraph from its text, as specified by the UBA. Setting the value |
2176 | to `right-to-left' or `left-to-right' forces a base direction on each | |
2177 | paragraph. | |
f4b6ba46 | 2178 | |
7d301ae6 CY |
2179 | Paragraphs with right-to-left base direction are displayed starting at |
2180 | the right window edge. | |
f1816485 | 2181 | |
dfdb4cad CY |
2182 | *** Enhanced support for characters with no glyphs in available fonts, |
2183 | or, on text terminals, characters that cannot be encoded by the | |
2184 | terminal coding system. The new option `glyphless-char-display-control' | |
2185 | specifies how to display them: as a hexadecimal code in a box, a thin | |
2186 | 1-pixel space, an empty box, etc. | |
d0ce9f8c | 2187 | |
9702b7a1 GM |
2188 | *** New input methods for Farsi and Bulgarian |
2189 | (farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic). | |
041d709f | 2190 | |
939db9ac CY |
2191 | *** `nobreak-char-display' now also highlights Unicode hyphen chars |
2192 | (U+2010 and U+2011). | |
2193 | ||
7d301ae6 | 2194 | *** New Hebrew translation of the Emacs Tutorial. |
31fd3586 GM |
2195 | Type `C-u C-h t' to choose it in case your language setup doesn't |
2196 | automatically select it. | |
2197 | ||
7d301ae6 CY |
2198 | ** An Emacs Lisp package manager is now included. |
2199 | This is a convenient way to download and install additional packages, | |
2200 | from a package repository at http://elpa.gnu.org. | |
dfdb4cad | 2201 | |
7d301ae6 CY |
2202 | *** M-x list-packages shows a list of packages, which can be |
2203 | selected for installation. | |
dfdb4cad | 2204 | |
7d301ae6 | 2205 | *** New command `describe-package', bound to `C-h P'. |
dfdb4cad | 2206 | |
7d301ae6 CY |
2207 | *** By default, all installed packages are loaded automatically when |
2208 | Emacs starts up. To disable this, set `package-enable-at-startup' to | |
2209 | nil. To specify the packages to load, customize `package-load-list'. | |
16a91140 | 2210 | |
dfdb4cad CY |
2211 | ** Custom theme changes |
2212 | ||
7d301ae6 CY |
2213 | *** New command `M-x customize-themes', which provides a convenient |
2214 | interface for enabling and disabling Custom themes. | |
dfdb4cad | 2215 | |
7d301ae6 | 2216 | *** New option `custom-theme-load-path' is the load path for themes. |
dfdb4cad CY |
2217 | Emacs no longer looks for Custom themes in `load-path'. The default |
2218 | value of `custom-theme-load-path' says to look for themes in | |
2219 | `custom-theme-directory', followed by a subdirectory of | |
2220 | `data-directory' named "themes/", which contains a small selection of | |
2221 | built-in Custom themes. | |
2222 | ||
7d301ae6 CY |
2223 | *** New option `custom-safe-themes' records known-safe theme files. |
2224 | If a theme is not in this list, Emacs queries before loading it, and | |
2225 | offers to save the theme to `custom-safe-themes' automatically. By | |
2226 | default, all themes included in Emacs are treated as safe. | |
b7d65a5f | 2227 | |
7d301ae6 | 2228 | ** Improved GTK integration |
dfdb4cad | 2229 | |
7d301ae6 | 2230 | *** GTK scroll-bars are now placed on the right by default. |
dfdb4cad CY |
2231 | The function `set-scroll-bar-mode' can change this. |
2232 | ||
7d301ae6 | 2233 | *** GTK tool bars can have just text, just images or images and text. |
dfdb4cad CY |
2234 | Customize `tool-bar-style' to choose the style. On a Gnome desktop, |
2235 | the default is taken from desktop settings. | |
2236 | ||
2237 | *** GTK tool bars can be placed on any edge of the frame. | |
7d301ae6 CY |
2238 | The frame-parameter tool-bar-position controls this. It takes the |
2239 | values top, left, right or bottom. The Options => Show/Hide menu has | |
2240 | entries for this. | |
dfdb4cad | 2241 | |
7d301ae6 CY |
2242 | *** The default colors for selected text (the `region' face) are taken |
2243 | from the GTK theme when Emacs is built with GTK. | |
dfdb4cad | 2244 | |
7d301ae6 CY |
2245 | *** Emacs uses GTK tooltips by default if built with GTK. |
2246 | You can disable this by changing `x-gtk-use-system-tooltips' to nil. | |
a5bee597 | 2247 | |
dfdb4cad CY |
2248 | ** Graphical interface changes |
2249 | ||
2250 | *** On graphical displays, the mode-line no longer ends in dashes. | |
2251 | Also, the first dash (which does not indicate anything) is just | |
2252 | displayed as a space. | |
2253 | ||
2254 | *** `menu-bar-select-buffer-function' lets you choose another operation | |
2255 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. | |
2256 | ||
2257 | *** Lucid menus and dialogs can display antialiased fonts if Emacs is | |
2258 | built with Xft. These fonts can be set via X resources, for example: | |
2259 | Emacs.pane.menubar.font: Courier-12 | |
2260 | ||
7d301ae6 | 2261 | ** Exiting changes |
dfdb4cad | 2262 | |
7d301ae6 | 2263 | *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP, |
dfdb4cad CY |
2264 | or if it receives a SIGINT signal in batch mode. |
2265 | ||
7d301ae6 CY |
2266 | *** `kill-emacs-hook' is now also run in batch mode. |
2267 | Third-party code which adds to `kill-emacs-hook' should check if they | |
2268 | do the right thing in batch mode. | |
9c524fcb | 2269 | |
041d709f | 2270 | ** Scrolling changes |
dfdb4cad | 2271 | |
041d709f | 2272 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' |
0a19a6f8 | 2273 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
7d301ae6 | 2274 | of buffer at first key-press (instead they move to top/bottom of buffer) |
550f41cd | 2275 | when `scroll-error-top-bottom' is non-nil. |
dfdb4cad CY |
2276 | |
2277 | *** New option `scroll-error-top-bottom' (see above). | |
2278 | ||
041d709f | 2279 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' |
5a97d2da | 2280 | scroll a line instead of full screen. |
dfdb4cad | 2281 | |
041d709f | 2282 | *** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 2283 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
dfdb4cad | 2284 | |
041d709f | 2285 | *** If you customize `scroll-conservatively' to a value greater than 100, |
d0f69533 EZ |
2286 | Emacs will never recenter point in the window when it scrolls due to |
2287 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | |
2288 | Previously, you needed to use `most-positive-fixnum' as the value of | |
2289 | `scroll-conservatively' to achieve the same effect. | |
dfdb4cad | 2290 | |
7d301ae6 | 2291 | *** "Aggressive" scrolling now honors the scroll margins. |
d0f69533 EZ |
2292 | If you customize `scroll-up-aggressively' or |
2293 | `scroll-down-aggressively' and move point off the window, Emacs now | |
2294 | scrolls the window so as to avoid positioning point inside the scroll | |
2295 | margin. | |
2296 | ||
7d301ae6 CY |
2297 | ** Basic SELinux support has been added. |
2298 | This requires Emacs to be linked with libselinux at build time. | |
f1a5d776 | 2299 | |
dfdb4cad CY |
2300 | *** Emacs preserves the SELinux file context when backing up. |
2301 | Also, the function `copy-file' has an extra optional argument for | |
2302 | preserving SELinux context, and the return value of `backup-buffer' | |
2303 | now includes the SELinux context. | |
f0bf7c8e | 2304 | |
dfdb4cad | 2305 | *** New functions `file-selinux-context' and `set-file-selinux-context' |
7d301ae6 | 2306 | get and set the SELinux context of a file. |
44198b6e | 2307 | |
7d301ae6 | 2308 | ** Trash changes |
dfdb4cad | 2309 | |
7d301ae6 CY |
2310 | *** `delete-by-moving-to-trash' now only affects commands that specify |
2311 | trashing. This avoids inadvertently trashing temporary files. | |
dfdb4cad | 2312 | |
7d301ae6 CY |
2313 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
2314 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
278f6845 | 2315 | |
041d709f | 2316 | ** File- and directory-local variable changes |
dfdb4cad | 2317 | |
041d709f CY |
2318 | *** You can stop directory local vars from applying to subdirectories. |
2319 | Add an element (subdirs . nil) to the alist portion of any variables | |
2320 | settings to indicate that the section should not apply to | |
2321 | subdirectories. | |
dfdb4cad | 2322 | |
041d709f CY |
2323 | *** Directory local variables can apply to some file-less buffers. |
2324 | Affected modes include dired, vc-dir, and log-edit. For example, | |
2325 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will | |
2326 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call | |
2327 | `hack-dir-local-variables-non-file-buffer' to support this. | |
dfdb4cad | 2328 | |
041d709f CY |
2329 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. |
2330 | Instead, use "eval: (minor-mode 1)". | |
c136e5cd | 2331 | |
7b447e9b GM |
2332 | *** The variable `inhibit-first-line-modes-regexps' has been renamed |
2333 | to `inhibit-local-variables-regexps'. As the name suggests, it now | |
dfdb4cad CY |
2334 | applies to ALL file local variables, not just -*- lines. The |
2335 | associated `inhibit-first-line-modes-suffixes' has been renamed in the | |
2336 | corresponding way. | |
5d907d6c | 2337 | |
0a2132ba CY |
2338 | ** Window changes |
2339 | ||
91b65361 CY |
2340 | *** The `quit-window' command now restores the last buffer displayed |
2341 | in the quitted window. | |
2342 | ||
0a2132ba CY |
2343 | *** Resizing an Emacs frame now preserves proportional window sizes, |
2344 | modulo restrictions like window minimum sizes and fixed-size windows. | |
2345 | ||
2346 | *** The behavior of `display-buffer' is now customizable in detail. | |
dfdb4cad | 2347 | |
0a2132ba CY |
2348 | **** New option `display-buffer-base-action' specifies a list of |
2349 | user-determined display "actions" (functions and optional arguments | |
2350 | for choosing the displaying window). | |
2351 | ||
2352 | This takes precedence over the default display action, which is | |
2353 | specified by `display-buffer-fallback-action'. | |
2354 | ||
2355 | **** New option `display-buffer-alist' maps buffer name regexps to | |
2356 | display actions, taking precedence over `display-buffer-base-action'. | |
2357 | ||
a0c2d0ae MR |
2358 | *** New option `window-combination-limit'. |
2359 | The new option `window-combination-limit' allows to return the space | |
2360 | obtained for resizing or creating a window more reliably to the window | |
2361 | from which such space was obtained. | |
0a2132ba | 2362 | |
a0c2d0ae MR |
2363 | *** New option `window-combination-resize'. |
2364 | The new option `window-combination-resize' allows to split a window that | |
2365 | otherwise cannot be split because it's too small by stealing space from | |
2366 | other windows in the same combination. Subsequent resizing or deletion | |
2367 | of the window will resize all windows in the same combination as well. | |
0a2132ba | 2368 | |
91b65361 CY |
2369 | *** New option `frame-auto-hide-function' lets you choose between |
2370 | iconifying or deleting a frame when burying a buffer in a dedicated | |
2371 | frame, or quitting a window showing a buffer in a frame of its own. | |
2372 | ||
0a2132ba | 2373 | *** New commands `maximize-window' and `minimize-window'. |
53964682 | 2374 | These maximize and minimize the size of a window within its frame. |
0a2132ba | 2375 | |
0a2132ba CY |
2376 | *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'. |
2377 | These functions allow to navigate through the live buffers that have | |
2378 | been shown in a specific window. | |
2379 | ||
7d301ae6 | 2380 | ** Minibuffer changes |
dfdb4cad | 2381 | |
7d301ae6 | 2382 | *** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. |
104dc9c6 GM |
2383 | This is handy for minibuffer-only frames, and is also used for the feature |
2384 | where mouse-1 pops up *Messages*"', which can now easily be changed. | |
041d709f | 2385 | |
7d301ae6 | 2386 | *** Minibuffers set `truncate-lines' to nil. |
f66eca26 | 2387 | If you want to change the value to something else, you could use |
7d301ae6 CY |
2388 | for example `minibuffer-setup-hook'. |
2389 | ||
7d301ae6 CY |
2390 | ** `auto-mode-case-fold' is now enabled by default. |
2391 | ||
7d301ae6 | 2392 | ** `backup-by-copying-when-mismatch' now defaults to t. |
f66eca26 | 2393 | |
dfdb4cad CY |
2394 | ** New basic faces `error', `warning', `success'. |
2395 | These are used to highlight text indicating failure, caution or | |
2396 | successful operation. | |
2397 | ||
2398 | ** New option `list-colors-sort' defines the color sort order | |
2399 | for `list-colors-display'. | |
2400 | ||
2401 | ** The variable `focus-follows-mouse' now always defaults to nil. | |

eb199145 | 2404 | * Editing Changes in Emacs 24.1 |
b350bdf2 | 2405 | |
892777ba | 2406 | ** Search changes |
dfdb4cad CY |
2407 | |
2408 | *** C-y in Isearch is now bound to `isearch-yank-kill', instead of | |
2409 | `isearch-yank-line'. | |
2410 | ||
2411 | *** M-y in Isearch is now bound to `isearch-yank-pop', instead of | |
2412 | `isearch-yank-kill'. | |
2413 | ||
2414 | *** M-s C-e in Isearch is now bound to `isearch-yank-line'. | |
2415 | ||
b2b0776e | 2416 | ** New commands `count-words-region' and `count-words'. |
dfdb4cad | 2417 | |
10607bea CY |
2418 | *** M-= is bound to `count-words-region', not `count-lines-region'. |
2419 | The `count-words-region' command, when called interactively, reports | |
2420 | the number of lines, words, and characters in the region. It is a | |
2421 | superset of the old `count-lines-region', which is now an obsolete | |
2422 | alias for it. | |
ea4f7750 | 2423 | |
ec9da840 | 2424 | ** The command `just-one-space' (M-SPC), if given a negative argument, |
1c708c1a CY |
2425 | also deletes newlines around point. |
2426 | ||
b9229673 | 2427 | ** Deletion changes |
dfdb4cad | 2428 | |
b9229673 | 2429 | *** New option `delete-active-region'. |
ddb54206 | 2430 | If non-nil, [delete] and DEL delete the region if it is active and no |
dfdb4cad | 2431 | prefix argument is given. If set to `kill', those commands kill |
ddb54206 | 2432 | instead. |
dfdb4cad | 2433 | |
59ee0542 | 2434 | *** New command `delete-forward-char', bound to [delete]. |
42d9cffa CY |
2435 | This is meant for interactive use, and obeys `delete-active-region'. |
2436 | The command `delete-char' does not obey `delete-active-region'. | |
dfdb4cad | 2437 | |
b9229673 CY |
2438 | *** `delete-backward-char' is now a Lisp function. |
2439 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
7d301ae6 CY |
2440 | However, the byte compiler now warns if it is called from Lisp; Lisp |
2441 | callers should use delete-char with a negative argument instead. | |
dfdb4cad | 2442 | |
b9229673 CY |
2443 | *** The option `mouse-region-delete-keys' has been deleted. |
2444 | ||
f9d71b42 CY |
2445 | ** Selection changes. |
2446 | ||
7d301ae6 CY |
2447 | The default handling of clipboard and primary selections has been |
2448 | changed to conform with modern X applications. In short, most | |
2449 | commands for killing and yanking text now use the clipboard, while | |
2450 | mouse commands use the primary selection. | |
b1ab31ae CY |
2451 | |
2452 | In the following, we provide a list of these changes, followed by a | |
2453 | list of steps to get the old behavior back if you prefer that. | |
2454 | ||
b1ab31ae CY |
2455 | *** `select-active-regions' now defaults to t. |
2456 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
963578d3 | 2457 | the kill ring. The selected text is put in the primary selection, if |
b1ab31ae CY |
2458 | the system possesses a separate primary selection facility (e.g. X). |
2459 | ||
2460 | **** `select-active-regions' also accepts a new value, `only'. | |
2461 | This means to only set the primary selection for temporarily active | |
2462 | regions (usually made by mouse-dragging or shift-selection); | |
2463 | "ordinary" active regions, such as those made with C-SPC followed by | |
2464 | point motion, do not alter the primary selection. | |
2465 | ||
963578d3 CY |
2466 | **** `mouse-drag-copy-region' now defaults to nil. |
2467 | ||
b1ab31ae CY |
2468 | *** mouse-2 is now bound to `mouse-yank-primary'. |
2469 | This pastes from the primary selection, ignoring the kill-ring. | |
2470 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
dfdb4cad | 2471 | |
b1ab31ae | 2472 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
dfdb4cad | 2473 | |
b1ab31ae CY |
2474 | *** `x-select-enable-primary' now defaults to nil. |
2475 | Thus, commands that kill text or copy it to the kill-ring (such as | |
2476 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
2477 | ||
2478 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now | |
dfdb4cad | 2479 | exactly equivalent to M-w, C-w, and C-y respectively. |
b1ab31ae CY |
2480 | |
2481 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already | |
2482 | non-nil by default, as Windows does not support the primary selection | |
2483 | between applications. | |
2484 | ||
2485 | *** To return to the previous behavior, do the following: | |
dfdb4cad | 2486 | |
104c2fe9 | 2487 | **** Change `select-active-regions' to nil. |
b1ab31ae CY |
2488 | **** Change `mouse-drag-copy-region' to t. |
2489 | **** Change `x-select-enable-primary' to t (on X only). | |
2490 | **** Change `x-select-enable-clipboard' to nil. | |
2491 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 2492 | |
084e6df3 | 2493 | *** Support for X cut buffers has been removed. |
dfdb4cad | 2494 | |
3fd50d5c CY |
2495 | *** X clipboard managers are now supported. |
2496 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. | |
4b80f674 | 2497 | |
dfdb4cad CY |
2498 | ** New command `C-x r N' (`rectangle-number-lines') numbers the lines |
2499 | in the current rectangle. With a prefix argument, this prompts for a | |
2500 | number to count from and for a format string. | |
99f053cf | 2501 | |
7d301ae6 | 2502 | ** `redisplay-dont-pause' now defaults to t. |
6bf7006f EZ |
2503 | This makes Emacs feel more responsive to editing commands that arrive |
2504 | at high rate, e.g. if you lean on some key, because stopping redisplay | |
2505 | in the middle (when this variable is nil) forces more expensive | |
2506 | updates later on, and Emacs appears to be unable to keep up. | |
2507 | ||
e70b5064 CY |
2508 | ** The behavior of <TAB> for active regions in Text mode has changed. |
2509 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | |
2510 | when the region is active causes Emacs to indent all the lines in the | |
2511 | region, aligning them with the line previous to the first line in the | |
2512 | region (or with the left margin if there is no previous line). | |
2513 | ||
dfdb4cad CY |
2514 | ** When `occur' is called with a prefix argument, matching strings are |
2515 | collected into the `*Occur*' buffer without line numbers. If there | |
2516 | are parenthesized subexpressions in the specified regexp, `occur' | |
2517 | reads replacement text that may contain \\& and \\N whose convention | |
2518 | follows `replace-match'. | |

eb199145 | 2521 | * Changes in Specialized Modes and Packages in Emacs 24.1 |
efeb796b | 2522 | |
041d709f | 2523 | ** Archive Mode has basic support for browsing and updating 7z archives. |
d76674bb | 2524 | |
b7c3692a | 2525 | ** BibTeX mode |
dfdb4cad | 2526 | |
2de69e00 | 2527 | *** BibTeX mode now supports biblatex. |
7d301ae6 CY |
2528 | Use the variable `bibtex-dialect' to select different BibTeX dialects. |
2529 | `bibtex-entry-field-alist' is now an obsolete alias for | |
2530 | `bibtex-BibTeX-entry-alist'. | |
2531 | ||
dfdb4cad CY |
2532 | *** New command `bibtex-search-entries', bound to C-c C-a. |
2533 | ||
b7c3692a | 2534 | *** New `bibtex-entry-format' option `sort-fields', disabled by default. |
dfdb4cad | 2535 | |

2536 | *** New variable `bibtex-search-entry-globally'. |
2537 | ||
7d301ae6 | 2538 | ** Browse-url |
dfdb4cad | 2539 | |
7d301ae6 | 2540 | *** New option `browse-url-mailto-function' specifies how to handle "mailto:"s. |
dfdb4cad | 2541 | |
7d301ae6 CY |
2542 | *** The default browser used by the package is now the "xdg-open" program, |
2543 | on platforms that support it. This calls your desktop's preferred browser. | |
2544 | ||
86e100a6 GM |
2545 | ** Calc |
2546 | ||
2547 | *** Support for musical notes. | |
2548 | ||
2549 | *** Support for logarithmic units. | |
2550 | ||
2551 | *** No longer uses the tex prefix for TeX specific unit names when | |
2552 | using TeX or LaTeX mode. | |
2553 | ||
2554 | *** New option to highlight selections using faces. | |
2555 | ||
2556 | *** `calc-histogram' has the option of using a vector to determine the bins. | |
2557 | ||
2558 | *** New "O" option prefix. | |
2559 | ||
2560 | *** Use the "O" prefix to "d r" (`calc-radix') to turn on twos-complement mode. | |
2561 | ||
cf16af42 GM |
2562 | ** Calendar, Diary, and Appt |
2563 | ||
7d301ae6 | 2564 | *** Diary entries can contain non-printing "comments". |
548d0a63 GM |
2565 | See the variable `diary-comment-start'. |
2566 | ||
5006e634 GM |
2567 | *** Appointments can specify their individual warning times. |
2568 | See the variable `appt-warning-time-regexp'. | |
2569 | ||
0a2bb1a9 GM |
2570 | *** The function specified by `appt-disp-window-function' may be passed |
2571 | lists of arguments if multiple appointments are due at similar times. | |
2572 | If you are using a custom function for this, you should update it. | |
2573 | ||
7454f200 GM |
2574 | *** New function `diary-hebrew-birthday'. |
2575 | ||
e565dd37 GM |
2576 | *** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array' |
2577 | may no longer be nil, but must all be strings. | |
2578 | ||
7d301ae6 CY |
2579 | *** The obsolete (since Emacs 22.1) method of enabling the appt |
2580 | package by adding `appt-make-list' to `diary-hook' has been removed. | |
2581 | Use `appt-activate' instead. | |
cf16af42 | 2582 | |
cf16af42 GM |
2583 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: |
2584 | appt-issue-message (use the function appt-activate) | |
2585 | appt-visible/appt-msg-window (use the variable appt-display-format) | |
2586 | ||
cf16af42 GM |
2587 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: |
2588 | view-diary-entries, list-diary-entries, show-all-diary-entries | |
2589 | ||
551b046f | 2590 | ** CC Mode |
dfdb4cad | 2591 | |
551b046f | 2592 | *** New feature to "guess" the style in an existing buffer. |
7d301ae6 | 2593 | The main entry point is M-x c-guess. |
041d709f | 2594 | |
551b046f AM |
2595 | *** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang). |
2596 | ||
dfdb4cad | 2597 | *** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes. |
551b046f AM |
2598 | Thus C-M-a will, by default, go to the beginning of the immediate function, |
2599 | not the top level. | |
2600 | ||
dfdb4cad | 2601 | *** "Macros with semicolons" can be registered for correct indentation. |
551b046f AM |
2602 | Where such a macro ends a line (no semicolon) the next statement is no longer |
2603 | parsed as a statement continuation. | |
2604 | ||
dfdb4cad | 2605 | ** Comint and modes derived from it use the standard completion code. |
041d709f CY |
2606 | |
2607 | ** Compilation mode | |
dfdb4cad | 2608 | |
7d301ae6 | 2609 | *** Compilation mode can be used without Font Lock mode. |
041d709f CY |
2610 | `compilation-parse-errors-function' is now obsolete. |
2611 | ||
dfdb4cad | 2612 | *** New variable `compilation-filter-start', which is bound while |
7d301ae6 CY |
2613 | `compilation-filter-hook' runs. It records the start position of the |
2614 | text inserted by `compilation-filter'. | |
041d709f | 2615 | |
47a6a35f GM |
2616 | *** `compilation-error-screen-columns' and `compilation-first-column' |
2617 | are obeyed in the editing buffer. So programming language modes can | |
7d301ae6 CY |
2618 | set them, whereas previously only the value in the *Compilation* |
2619 | buffer was used. | |
1dce7193 | 2620 | |
52834b6b CY |
2621 | ** Customize |
2622 | ||
2623 | *** Customize buffers now contain a search field. | |
2624 | The search is performed using `customize-apropos'. | |
7d301ae6 | 2625 | To turn off the search field, set `custom-search-field' to nil. |
52834b6b | 2626 | |
8d5dd370 | 2627 | *** Options in customize group buffers start out hidden if not customized. |
52834b6b CY |
2628 | Use the arrow to the left of the option name to toggle visibility. |
2629 | ||
2630 | *** custom-buffer-sort-alphabetically now defaults to t. | |
2631 | ||
2632 | *** The color widget now has a "Choose" button, which allows you to | |
7d301ae6 | 2633 | choose a color via `list-colors-display'. |
52834b6b | 2634 | |
041d709f CY |
2635 | ** D-Bus |
2636 | ||
5da3be7f GM |
2637 | *** It is now possible to access buses other than the default system |
2638 | or session bus. | |
041d709f | 2639 | |
7d301ae6 | 2640 | *** The `dbus-register-method' and `dbus-register-property' functions |
5da3be7f | 2641 | optionally do not register names. |
041d709f | 2642 | |
7d301ae6 | 2643 | *** The new function `dbus-register-service' registers a known service |
dfdb4cad | 2644 | name on a D-Bus without also registering a property or a method. |
041d709f | 2645 | |
f5d6548a | 2646 | ** Dired-x |
425a25f1 | 2647 | |
7d301ae6 CY |
2648 | *** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'), |
2649 | if called with a prefix argument, read a file name from the minibuffer | |
2650 | instead of using the current buffer. | |
f5d6548a | 2651 | |
7d301ae6 | 2652 | *** The "dired local variables" feature of Dired-x is obsolete. |
817b48a7 | 2653 | The standard directory local variables feature replaces it. |
8117868f | 2654 | |
041d709f | 2655 | ** ERC changes |
7492acc9 | 2656 | |
c4077254 GM |
2657 | *** New options `erc-autojoin-timing' and `erc-autojoin-delay', |
2658 | controlling attempts to autojoin a channel. | |
041d709f CY |
2659 | |
2660 | *** New variable `erc-coding-system-precedence': If we use `undecided' | |
2661 | as the server coding system, this variable will then be consulted. | |
2662 | The default is to decode strings that can be decoded as utf-8 as | |
2663 | utf-8, and do the normal `undecided' decoding for the rest. | |
7492acc9 | 2664 | |
041d709f | 2665 | ** Eshell changes |
7492acc9 | 2666 | |
05f77e38 GM |
2667 | *** The default value of `eshell-directory-name' has changed |
2668 | to be an "eshell" directory in `user-emacs-directory'. | |
2669 | The old "~/.eshell/" directory is still used if it exists, though. | |
041d709f CY |
2670 | |
2671 | ** gdb-mi | |
dfdb4cad CY |
2672 | |
2673 | *** The M-x gdb command now uses the GDB Machine Interface protocol. | |
05f77e38 GM |
2674 | It now supports multithread non-stop debugging and simultaneous |
2675 | debugging of several threads. | |
7492acc9 | 2676 | |
18af70d0 CY |
2677 | ** Image mode |
2678 | ||
05f77e38 GM |
2679 | *** RET (`image-toggle-animation') toggles animation, if applicable. |
2680 | Animation plays once, unless the option `image-animate-loop' is non-nil. | |
18af70d0 | 2681 | |
041d709f | 2682 | ** Info |
723ee192 | 2683 | |
7d301ae6 | 2684 | *** New command M-x info-display-manual displays a named Info manual. |
2ebc3b94 GM |
2685 | If that manual is already visited in some Info buffer, it displays |
2686 | that buffer. (This is handy if you have many manuals in many *info* | |
2687 | buffers, and don't remember the name of the buffer visiting the manual | |
2688 | you want to consult.) Otherwise, it loads and displays the manual. | |
691cf4a0 | 2689 | |
24ea72d3 EZ |
2690 | *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'. |
2691 | This is for compatibility with the stand-alone Info reader program, | |
2692 | and also because `Info-edit' is a rarely used command that is disabled | |
2693 | by default. | |
2694 | ||
7d301ae6 | 2695 | ** Mail mode changes (not Message mode) |
dfdb4cad | 2696 | |
7d301ae6 | 2697 | *** New command M-x mail-add-attachment for adding MIME attachments |
7d301ae6 | 2698 | |
dfdb4cad CY |
2699 | *** The command M-x mail-attach-file was renamed to M-x mail-insert-file. |
2700 | (Its name is misleading, since it has nothing to do with MIME | |
2701 | attachments.) The old name is now an obsolete alias to the new name. | |
2702 | ||
f2c3a9eb | 2703 | ** MH-E has been updated to MH-E version 8.3.1. |
041d709f | 2704 | See MH-E-NEWS for details. |
37221432 | 2705 | |
041d709f | 2706 | ** Modula-2 mode provides auto-indentation. |
37221432 | 2707 | |
041d709f | 2708 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
3c3d4f5b | 2709 | |
5d1ac394 | 2710 | ** nXML mode no longer binds C-RET to `nxml-complete'. |
dfdb4cad CY |
2711 | Completion is now performed via `completion-at-point', bound to C-M-i |
2712 | or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the | |
2713 | default), this performs tag completion. | |
5d1ac394 | 2714 | |
f2c3a9eb CY |
2715 | ** Org mode has been updated to version 7.8.09. |
2716 | See ORG-NEWS for details. | |
2717 | ||
041d709f | 2718 | ** Prolog mode has been completely revamped, with lots of additional |
7d301ae6 CY |
2719 | functionality such as more intelligent indentation, electricity, |
2720 | support for more variants, including Mercury, and a lot more. | |
041d709f CY |
2721 | |
2722 | ** Rmail | |
2723 | ||
2724 | *** The command `rmail-epa-decrypt' decrypts OpenPGP data | |
2725 | in the Rmail incoming message. | |
2726 | ||
50419064 GM |
2727 | *** The variable `rmail-message-filter' no longer has any effect. |
2728 | This change was made in Emacs 23.1 but was not advertised at the time. | |
2729 | Try using `rmail-show-message-hook' instead. | |
2730 | ||
717a1362 | 2731 | ** Shell mode |
dfdb4cad CY |
2732 | |
2733 | *** M-x shell prompts for the shell path name if the default directory | |
2734 | is a remote file name and neither the environment variable $ESHELL nor | |
2735 | the variable `explicit-shell-file-name' is set. | |
2736 | ||
2737 | *** TAB is now bound to the standard `completion-at-point' command, | |
2738 | which now implements the pcomplete rules for shell command completion. | |
717a1362 | 2739 | |
7d301ae6 CY |
2740 | ** SMTPmail |
2741 | ||
dfdb4cad | 2742 | *** SMTPmail now uses encrypted connections (via STARTTLS) by default |
7d301ae6 CY |
2743 | if the mail server supports them. This uses either built-in GnuTLS |
2744 | support, or the starttls.el library. Customize `smtpmail-stream-type' | |
2745 | to change this. | |
2746 | ||
7d301ae6 CY |
2747 | *** The variable `smtpmail-auth-credentials' has been removed. |
2748 | By default, the information is now stored in the file ~/.authinfo. | |
dfdb4cad CY |
2749 | This was the default value of smtpmail-auth-credentials. If you had |
2750 | customized smtpmail-auth-credentials to a list of user names and | |
2751 | passwords, those settings are not used. During your first connection | |
2752 | to the smtp server, Emacs will prompt for the user name and password, | |
2753 | and offer to save them to ~/.authinfo. Or you can manually copy the | |
2754 | credentials to ~/.authinfo. For example, if you had | |
7d301ae6 CY |
2755 | |
2756 | (setq smtpmail-auth-credentials | |
2757 | '(("mail.example.org" 25 "jim" "s!cret"))) | |
2758 | ||
2759 | then the equivalent line in ~/.authinfo would be | |
2760 | ||
2761 | machine mail.example.org port 25 login jim password s!cret | |
2762 | ||
2763 | See the auth-source manual for more information, e.g. on encrypting | |
2764 | the credentials file. | |
2765 | ||
7d301ae6 | 2766 | *** The variable `smtpmail-starttls-credentials' has been removed. |
dfdb4cad | 2767 | If you had that set, you need to put |
7d301ae6 CY |
2768 | |
2769 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert" | |
2770 | ||
2771 | in your ~/.authinfo file instead. | |
2772 | ||
8ce192e3 LI |
2773 | *** SMTPmail defaults to using the address in the From: header as the |
2774 | SMTP MAIL FROM envelope. To override this, set `mail-envelope-from' | |
2775 | to the address you wish to use instead. | |
2776 | ||
34e8a2da | 2777 | ** SQL mode |
041d709f | 2778 | |
34e8a2da GM |
2779 | *** New options `sql-port', `sql-connection-alist', `sql-send-terminator', |
2780 | and `sql-oracle-scan-on'. | |
041d709f | 2781 | |
dfdb4cad | 2782 | *** New options controlling prompting for login parameters. |
34e8a2da GM |
2783 | Each supported product has a custom variable `sql-*-login-params', |
2784 | which is a list of the parameters to be prompted for before a | |
2785 | connection is established. | |
041d709f CY |
2786 | |
2787 | *** The command `sql-product-interactive' now takes a prefix argument, | |
34e8a2da | 2788 | which causes it to prompt for an SQL product. |
041d709f | 2789 | |
34e8a2da | 2790 | *** Product-specific SQL interactive commands now take prefix arguments. |
041d709f CY |
2791 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), |
2792 | given a prefix argument, prompt for a name for the SQL interactive | |
2793 | buffer. This reduces the need for calling `sql-rename-buffer'. | |
2794 | ||
2795 | *** SQL interactive modes suppress command continuation prompts, and | |
2796 | replace tabs with spaces. The first change impacts multiple line SQL | |
2797 | statements entered with C-j between each line, statements yanked into | |
2798 | the buffer and statements sent with `sql-send-*' functions. The | |
34e8a2da GM |
2799 | second prevents the MySQL and Postgres interpreters from listing |
2800 | object name completions when sent text via `sql-send-*' functions. | |
041d709f CY |
2801 | |
2802 | *** New command `sql-connect' starts a predefined SQLi session, | |
2803 | using the login parameters from `sql-connection-alist'. | |
2804 | ||
2805 | *** New "Save Connection" menu item in SQLi buffers. | |
2806 | This gathers the login params specified for the SQLi session, if it | |
2807 | was not started by a connection, and saves them as a new connection. | |
2808 | ||
34e8a2da GM |
2809 | *** New commands for listing database objects and details: |
2810 | sql-list-all and sql-list-table. | |
041d709f CY |
2811 | |
2812 | *** An API for manipulating SQL product definitions has been added. | |
2813 | ||
2814 | ** TeX modes | |
2815 | ||
2816 | *** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. | |
412b9ee5 | 2817 | |
459bba37 | 2818 | ** Tramp |
dfdb4cad | 2819 | |
7d301ae6 | 2820 | *** New inline access method "ksu" (kerberized su). |
dfdb4cad | 2821 | |
459bba37 | 2822 | *** The following access methods are discontinued: "ssh1_old", |
ea843702 | 2823 | "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish". |
dfdb4cad | 2824 | |
b011fbfe GM |
2825 | *** The user option `remote-file-name-inhibit-cache' controls whether |
2826 | remote file attributes are cached for better performance. | |
dfdb4cad | 2827 | |
58f74fe4 MA |
2828 | *** The option `ange-ftp-binary-file-name-regexp' has changed its |
2829 | default value to "". | |
dfdb4cad | 2830 | |
7d301ae6 CY |
2831 | *** Handlers for `file-selinux-context' and `set-file-selinux-context' |
2832 | for remote machines which support SELinux. | |
58f74fe4 | 2833 | |
dfdb4cad | 2834 | ** New function `url-queue-retrieve', which behaves like url-retrieve, |
a48ec60c GM |
2835 | but with limits (`url-queue-parallel-processes', `url-queue-timeout') on |
2836 | the degree of parallelism. | |
177549d0 | 2837 | |
0c32ce32 CY |
2838 | ** VC and related modes |
2839 | ||
2840 | *** Support for pulling on distributed version control systems. | |
7d301ae6 CY |
2841 | The command C-x v + (`vc-pull') runs a "pull" operation, if it is |
2842 | supported (currently with Bzr, Git, and Mercurial), to update the | |
2843 | current branch and working tree. A prefix argument means to prompt | |
2844 | the user for specifics, e.g. a pull location. | |
0c32ce32 | 2845 | |
dab3703d | 2846 | *** `vc-update' is now an alias for `vc-pull'. |
0c32ce32 CY |
2847 | |
2848 | *** Support for merging on distributed version control systems. | |
7d301ae6 CY |
2849 | The command C-x v m (`vc-merge') now runs a "merge" operation, if it |
2850 | is supported (currently with Bzr, Git, and Mercurial), to merge | |
2851 | changes from another branch into the current one. It prompts for | |
2852 | specifics, e.g. a merge source. | |
0c32ce32 | 2853 | |
2afef60a | 2854 | *** New option `vc-revert-show-diff' controls whether `vc-revert' |
bbe43420 | 2855 | shows a diff while querying the user. It defaults to t. |
2afef60a | 2856 | |
d4eb88c7 CY |
2857 | *** Log entries in some Log View buffers can be toggled to display a |
2858 | longer description by typing RET (log-view-toggle-entry-display). | |
dab3703d GM |
2859 | This is currently supported for Bzr, Git, and Mercurial (to support |
2860 | another backend, define a `log-view-expanded-log-entry-function'). | |
7d301ae6 | 2861 | In the Log View buffers made by C-x v L (`vc-print-root-log'), you can |
d4eb88c7 CY |
2862 | use this to display the full log entry for the revision at point. |
2863 | ||
1c6c854e CS |
2864 | *** New command `vc-ediff' allows visual comparison of two revisions |
2865 | of a file similar to `vc-diff', but using ediff backend. | |

2932 | ** pcase.el provides the ML-style pattern matching macro `pcase'. |
2933 | ||
7725ebb7 MA |
2934 | ** secrets.el is an implementation of the Secret Service API, an |
2935 | interface to password managers like GNOME Keyring or KDE Wallet. The | |
065f2743 MA |
2936 | Secret Service API requires D-Bus for communication. The command |

2956 | * Incompatible Lisp Changes in Emacs 24.1 | |
6dfcbe31 | 2957 | |
7d301ae6 CY |
2958 | ** Passing a nil argument to a minor mode function call now ENABLES |
2959 | the minor mode unconditionally. This is so that you can write e.g. | |
2960 | ||
dfdb4cad | 2961 | (add-hook 'text-mode-hook 'foo-mode) |
7d301ae6 | 2962 | |
dfdb4cad CY |
2963 | to enable foo-mode in Text mode buffers, removing the need for |
2964 | `turn-on-foo-mode' style functions. This affects all mode commands | |
2965 | defined by `define-minor-mode'. If called interactively, the mode | |
2966 | command still toggles the minor mode. | |
7d301ae6 | 2967 | |
d268b4fe CY |
2968 | ** The return value of `backup-buffer' has changed. |
2969 | It is now a list of three elements, where the second element is a list | |
2970 | describing the original file's SELinux context. If Emacs or the | |
f003f294 | 2971 | system lacks SELinux support, the context list is (nil nil nil nil). |
7d301ae6 | 2972 | See "Basic SELinux support" above, under "Changes in Emacs 24.1". |
d268b4fe | 2973 | |
dfdb4cad CY |
2974 | ** `char-direction-table' and the `char-direction' function were deleted. |
2975 | They were buggy and inferior to the new support of bidirectional | |
2976 | editing introduced in Emacs 24. If you need the bidirectional | |
2977 | properties of a character, use `get-char-code-property' with the last | |
2978 | argument `bidi-class'. | |
fa6996bc | 2979 | |
470d996d TV |
2980 | ** `copy-directory' now copies the source directory as a subdirectory |
2981 | of the target directory, if the latter is an existing directory. The | |
2982 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy | |
2983 | the contents directly into a pre-existing target directory. | |
2984 | ||
9173a8fb CY |
2985 | ** For mouse click input events in the text area, the Y pixel |
2986 | coordinate in the POSITION list now counts from the top of the text | |
2987 | area, excluding any header line. Previously, it counted from the top | |
2988 | of the header line. | |
2989 | ||
7d301ae6 CY |
2990 | ** Support for "old-style" backquotes, obsolete for 10+ years, has |
2991 | been further reduced. Now a backquote not followed by a space is | |
2992 | always treated as a "new-style" backquote. Please remove all | |
2993 | "old-style" backquotes from your code. If your code uses backquotes | |
2994 | as documented in the Elisp manual, and compiles without warning, then | |
2995 | you have nothing to do in this regard. Code not following the | |
2996 | appropriate conventions may fail to compile. | |
50ab02c5 CY |
2997 | |
2998 | The most common cause of trouble seems to be an old-style backquote | |
2999 | followed by a newline. Another cause of trouble is vector notation | |
3000 | for key sequence notation: instead of [(control ,)] and [(control ')], | |
3001 | you should write [(control ?,)] and [(control ?')], which will work in | |
7d301ae6 | 3002 | older Emacsen too. |

3006 | replaced all known uses. | |
3007 | ||
7d301ae6 CY |
3008 | ** `view-buffer' now treats special mode-class in the same way that |
3009 | `view-file' has since Emacs 22 (i.e. it won't enable View mode if the | |
3010 | major mode is special). | |
fd5c9dfa | 3011 | |
7d301ae6 | 3012 | ** Menu and tool bar changes |

0a19a6f8 JB |
3015 | and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'. |
3016 | With these alist entries omitted, `make-frame' checks the value of the | |
3017 | variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create | |
3018 | a menu-bar or tool-bar, respectively. If the alist entries are added, | |
3019 | they override the value of `menu-bar-mode'/`tool-bar-mode'. | |
6431f2e6 | 3020 | |
7d301ae6 CY |
3021 | *** The menu bar bindings's caches are not used any more. |
3022 | Use (where-is-internal <def> nil t) instead. | |
3023 | ||
fe0aa820 | 3024 | ** Regions created by mouse dragging are now normal active regions, |
dfdb4cad | 3025 | similar to those created by shift-selection (see Selection changes |
7d301ae6 CY |
3026 | above). In previous Emacs versions, these regions were delineated by |
3027 | `mouse-drag-overlay'; that variable has been removed. | |
d6d8ee7a | 3028 | |
7d301ae6 CY |
3029 | ** The fourth argument of `filter-buffer-substring' has been removed. |
3030 | If you want to remove text properties from the final result, simply | |

9097e8af | 3084 | |
041d709f | 3085 | ** Code can now use lexical scoping by default instead of dynamic scoping. |
dfdb4cad | 3086 | The `lexical-binding' variable enables lexical scoping for local |
48da7392 | 3087 | variables. It is typically set via a file-local variable in the first |
dfdb4cad CY |
3088 | line of the file, in which case it applies to all the code in that |
3089 | file. | |
3090 | ||
041d709f CY |

3092 | binding instead of the old dynamic binding mode. | |
dfdb4cad | 3093 | |
041d709f CY |
3094 | *** Lexically scoped interpreted functions are represented with a new form |
3095 | of function value which looks like (closure ENV ARGS &rest BODY). | |
3096 | ||
3097 | *** New macro `letrec' to define recursive local functions. | |
dfdb4cad CY |
3098 | |
3099 | *** `defvar' and `defconst' now mark the variable as special (dynamic). | |
3100 | So do `defcustom' and other forms that call `defvar' as a subroutine. | |
3101 | ||
041d709f CY |
3102 | *** New function `special-variable-p' to check whether a variable is |
3103 | declared as dynamically bound. | |
3104 | ||
88ed9e87 SM |
3105 | *** The form ((lambda ...) ...) is deprecated. |

3111 | ** Changes for bidirectional display and editing | |
f1816485 | 3112 | |
041d709f | 3113 | *** New function `current-bidi-paragraph-direction'. |
7d301ae6 | 3114 | This returns the base direction of the paragraph at point. |
041d709f | 3115 | |
041d709f | 3116 | *** New function `bidi-string-mark-left-to-right'. |
dfdb4cad CY |
3117 | Given a string containing characters from right-to-left scripts, this |
3118 | function returns another string which can be safely inserted into a | |
3119 | buffer, such that any following text will be always displayed to the | |
7d301ae6 CY |
3120 | right of that string. (This works by appending an invisible Unicode |
3121 | "LEFT-TO-RIGHT MARK" character if the argument string might need it.) | |
041d709f | 3122 | |
7d301ae6 | 3123 | This is useful when the buffer has overall left-to-right paragraph |
dfdb4cad CY |
3124 | direction and you need to insert a string whose contents are not known |
3125 | in advance, without disrupting the layout of the line. | |

c4682d18 MR |
3129 | *** Window tree functions are accessible in Elisp. |
3130 | Functions are provided to return the parent, siblings or child windows | |
3131 | of any window including internal windows (windows not associated with a | |
3132 | buffer) in the window tree. | |
dfdb4cad | 3133 | |
24300f5f CY |
3134 | **** New function `window-valid-p' gives non-nil for live and internal |
3135 | windows. | |
dfdb4cad | 3136 | |
24300f5f | 3137 | **** Window manipulation can deal with internal windows. |
c4682d18 MR |
3138 | Many window handling functions like `split-window', `delete-window', or |
3139 | `delete-other-windows' as well as the window resizing functions can now | |
3140 | act on any window including internal ones. | |
dfdb4cad | 3141 | |
c4682d18 MR |
3142 | *** window-total-height/-width vs window-body-height/-width. |
3143 | The function `window-height' has been renamed to `window-total-height' | |
3144 | and `window-width' has been renamed to `window-body-width'. The old | |
3145 | names are provided as aliases. Two new functions `window-total-width' | |
3146 | and `window-body-height' are provided. | |
dfdb4cad | 3147 | |
c4682d18 MR |
3148 | *** Window parameters specific to window handling functions. |
3149 | For each window you can specify a parameter to override the default | |
3150 | behavior of a number of functions like `split-window', `delete-window' | |
ed6235ea MR |
3151 | and `delete-other-windows'. The variable `ignore-window-parameters' |
3152 | allows to ignore processing such parameters. | |
dfdb4cad | 3153 | |
c4682d18 | 3154 | *** New semantics of third argument of `split-window'. |
c4682d18 MR |
3155 | The third argument of `split-window' has been renamed to SIDE and can be |
3156 | set to any of the values 'below, 'right, 'above, or 'left to make the | |
3157 | new window appear on the corresponding side of the window that shall be | |
3158 | split. Any other value of SIDE will cause `split-window' to split the | |
3159 | window into two side-by-side windows as before. | |
dfdb4cad | 3160 | |
c4682d18 | 3161 | *** Window resizing functions. |
487ffd7a | 3162 | A new standard function for resizing windows called `window-resize' has |
c4682d18 MR |
3163 | been introduced. This and all other functions for resizing windows no |
3164 | longer delete any windows when they become too small. | |
dfdb4cad | 3165 | |
b3c0dbfd MR |
3166 | *** Deleting the selected window now selects the most recently selected |
3167 | live window on that frame instead. | |
dfdb4cad | 3168 | |
c4682d18 MR |
3169 | *** `adjust-window-trailing-edge' adjustments. |
3170 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | |
3171 | is able to resize other windows if a window adjacent to the trailing | |
3172 | edge cannot be shrunk any more. This makes its behavior more similar to | |
3173 | that of Emacs 21 without compromising, however, its inability to delete | |
3174 | windows which was introduced in Emacs 22. | |
dfdb4cad | 3175 | |
c4682d18 MR |
3176 | *** Window-local buffer lists. |
3177 | Windows now have local buffer lists. This means that removing a buffer | |
3178 | from display in a window will preferably show the buffer previously | |
3179 | shown in that window with its previous window-start and window-point | |
3180 | positions. This also means that the same buffer may be automatically | |
3181 | shown twice even if it already appears in another window. | |
dfdb4cad | 3182 | |
bee0fcef CY |
3183 | *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW, |
3184 | which if non-nil requires the buffer to be displayed in the currently | |
3185 | selected window, signaling an error otherwise. If nil, another window | |
3186 | can be used, e.g. if the selected one is strongly dedicated. | |
dfdb4cad | 3187 | |
0a2132ba | 3188 | *** `split-window-vertically' and `split-window-horizontally' renamed |
2d197ffb CY |
3189 | to `split-window-below' and `split-window-right' respectively. |
3190 | The old names are kept as aliases. | |
dfdb4cad | 3191 | |
0a2132ba CY |
3192 | *** Display actions |
3193 | ||
3194 | **** The second arg to `display-buffer' and `pop-to-buffer' is now | |
3195 | named ACTION, and takes a display action of the same form as | |
3196 | `display-buffer-base-action' (see Changes, above). A non-nil, | |
3197 | non-list value is treated specially, as the old meaning. | |
3198 | ||
3199 | **** New variable `display-buffer-overriding-action'. | |
3200 | ||
3201 | **** The procedure of `display-buffer' etc. to choose a window is | |
3202 | determined by combining `display-buffer-overriding-action', | |
3203 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', | |
3204 | and `display-buffer-fallback-action'. The second and fourth of these | |
3205 | are user-customizable variables. | |

3207 | See the docstring of `display-buffer' for details. | |
bee0fcef | 3208 | |
20d2304d CY |
3209 | *** New functions `window-state-get' and `window-state-put'. |
3210 | These functions allow to save and restore the state of an arbitrary | |
3211 | frame or window as an Elisp object. | |
3212 | ||
a2a25d24 | 3213 | ** Completion |
041d709f | 3214 | |
7d301ae6 CY |
3215 | *** New variable `completion-extra-properties' used to specify extra |
3216 | properties of the current completion: | |
a2a25d24 SM |
3217 | - :annotate-function, same as the old completion-annotate-function. |
3218 | - :exit-function, function to call after completion took place. | |
3219 | ||
7d301ae6 CY |
3220 | *** Functions on `completion-at-point-functions' can return any of the |
3221 | properties valid for `completion-extra-properties'. | |
a2a25d24 | 3222 | |
7d301ae6 | 3223 | *** `completion-annotate-function' is obsolete. |
a2a25d24 | 3224 | |
620c53a6 SM |
3225 | *** New `metadata' method for completion tables. The metadata thus returned |
3226 | can specify various details of the data returned by `all-completions': | |
3227 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | |
3228 | used to select a style in completion-category-overrides. | |
3229 | - `annotation-function' to add annotations in *Completions*. | |
3230 | - `display-sort-function' to specify how to sort entries in *Completions*. | |
3231 | - `cycle-sort-function' to specify how to sort entries when cycling. | |
3232 | ||
7d301ae6 CY |
3233 | *** `minibuffer-local-filename-must-match-map' is not used any more. |
3234 | Instead, the bindings in `minibuffer-local-filename-completion-map' | |
3235 | are combined with `minibuffer-local-must-match-map'. | |
de09aa52 CY |
3236 | |
3237 | *** New variable `completing-read-function' allows overriding the | |
3238 | behavior of `completing-read'. | |
3239 | ||
f042970d | 3240 | ** `glyphless-char-display' can now distinguish between graphical and |
16a43933 CY |
3241 | text terminal display, via a char-table entry that is a cons cell. |
3242 | ||
7d301ae6 | 3243 | ** `pre-command-hook'/`post-command-hook' are not reset to nil on error. |
f6d62986 SM |
3244 | Instead, the offending function is removed. |
3245 | ||
b1f6fa26 CY |
3246 | ** New hook types |
3247 | ||
3248 | *** New function `run-hook-wrapped' for running an abnormal hook by | |
3249 | passing the hook functions as arguments to a "wrapping" function. | |
e7bc51d0 | 3250 | Like `run-hook-with-args-until-success', it stops at the first |
5385447f | 3251 | non-nil return value. |
e7bc51d0 | 3252 | |
b1f6fa26 CY |
3253 | *** New macro `with-wrapper-hook' for running an abnormal hook as a |
3254 | set of "wrapping" filters, similar to around advice. | |
54521c99 GM |
3255 | (A version of this macro was actually added in Emacs 23.2 but was not |
3256 | advertised at the time.) | |
f6d62986 | 3257 | |
0b19b281 | 3258 | ** Debugger changes |
dfdb4cad | 3259 | |
0b19b281 | 3260 | *** New macro `condition-case-unless-debug' (this was actually added in |
1be3ca5a | 3261 | Emacs 23.1 as condition-case-no-debug, but not advertised) |
dfdb4cad | 3262 | |
0b19b281 | 3263 | *** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised. |
dfdb4cad | 3264 | |
0b19b281 | 3265 | *** Variable `stack-trace-on-error' removed. |
dfdb4cad | 3266 | |
0b19b281 CY |
3267 | *** The debugger can now "continue" from an error, which means it will |
3268 | jump to the error handler as if the debugger had not been invoked | |
3269 | instead of jumping all the way to the top-level. | |
dfdb4cad | 3270 | |
0b19b281 CY |
3271 | *** Set `debug-on-event' to enter the debugger on events like SIGUSR1. |
3272 | This can be useful when `inhibit-quit' is set. | |
d6b1d521 | 3273 | |
953cebf5 | 3274 | ** The new function `server-eval-at' allows evaluation of Lisp forms on |
37576acd | 3275 | named Emacs server instances. |
7deebf1b | 3276 | |
1b9f60cc GM |
3277 | ** `call-process' and `call-process-region' allow a `(:file "file")' spec |
3278 | to redirect STDOUT to a file. | |
7deebf1b | 3279 | |
7d301ae6 CY |
3280 | ** The function `format-time-string' now supports the %N directive, |
3281 | for higher-resolution time stamps. | |
da97a9e6 | 3282 | |
0b19b281 | 3283 | ** New input reading functions |
dfdb4cad | 3284 | |
0b19b281 CY |
3285 | *** New function `read-char-choice' reads a restricted set of |
3286 | characters, discarding any inputs not inside the set. | |
dfdb4cad | 3287 | |
0b19b281 CY |
3288 | *** The command `read-color' now requires a match for a color name |
3289 | or RGB triplet, instead of signaling an error if the user provides | |
3290 | invalid input. | |
dfdb4cad | 3291 | |
0b19b281 | 3292 | **** `facemenu-read-color' is now an alias for `read-color'. |
3ef01959 | 3293 | |
2e288d54 JB |
3294 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
3295 | The variable is now used to load all kind of supported dynamic libraries, | |
3296 | not just image libraries. The previous name is still available as an | |
3297 | obsolete alias. | |
3298 | ||
0b19b281 | 3299 | ** Syntax parsing changes |
dfdb4cad | 3300 | |
0b19b281 | 3301 | *** New variable `syntax-propertize-function'. |
04e2ce72 | 3302 | This replaces `font-lock-syntactic-keywords' which is now obsolete. |
cf38dd42 SM |
3303 | This allows syntax-table properties to be set independently from font-lock: |
3304 | just call syntax-propertize to make sure the text is propertized. | |
3305 | Together with this new variable come a new hook | |
3306 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
3307 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
3308 | as-is; and syntax-propertize-rules which provides a new way to specify | |
3309 | syntactic rules. | |
dfdb4cad | 3310 | |
0b19b281 | 3311 | *** Syntax tables support a new "comment style c" additionally to style b. |
a2e5caf7 | 3312 | |
7d301ae6 | 3313 | ** New hook `post-self-insert-hook', run after `self-insert-command'. |
041d709f | 3314 | |
4e2db1fe | 3315 | ** frame-local variables cannot be let-bound any more. |
041d709f | 3316 | |
15de15c6 | 3317 | ** Major and minor mode changes |
dfdb4cad | 3318 | |
0b19b281 CY |
3319 | *** `set-auto-mode' now respects mode: local variables at the end of files, |
3320 | as well as those in the -*- line. | |
dfdb4cad | 3321 | |
15de15c6 CY |
3322 | *** `prog-mode' is a new major mode from which programming modes |
3323 | should be derived. | |
dfdb4cad | 3324 | |
15de15c6 CY |
3325 | **** `prog-mode-hook' can be used to enable features for programming |
3326 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable | |
3327 | on-the-fly spell checking for comments and strings. | |
dfdb4cad | 3328 | |
14dd22d2 JB |
3329 | **** New minor modes `prettify-symbols-mode' and |
3330 | `global-prettify-symbols-mode' let the user enable symbol | |
3331 | prettification (replacing a string like "lambda" with the Greek lambda | |
3332 | character). | |
398b4366 | 3333 | |
15de15c6 CY |
3334 | *** New hook `change-major-mode-after-body-hook', run by |
3335 | `run-mode-hooks' just before any other mode hooks. | |
dfdb4cad | 3336 | |
7a9a2fc6 GM |
3337 | *** Enabled globalized minor modes can be disabled in specific major modes. |
3338 | If the global mode is global-FOO-mode, then run (FOO-mode -1) in the | |
3339 | major mode's hook, where FOO-mode toggles the mode on a per-buffer basis. | |
dfdb4cad | 3340 | |
feb8a83a | 3341 | *** `define-minor-mode' accepts new keywords :variable, :after-hook. |
f44379e7 | 3342 | |
7d301ae6 CY |
3343 | ** File-handling changes |
3344 | ||
7d301ae6 | 3345 | *** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
3346 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
3347 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
3348 | argument is supplied (see Trash changes, above). | |
53967e09 | 3349 | |
7d301ae6 | 3350 | *** New file predicates: `file-equal-p', `file-in-directory-p'. |
ec70a47d | 3351 | |
4039c786 CY |
3352 | ** Tool-bars can display separators. |
3353 | Tool-bar separators are handled like menu separators in menu-bar maps, | |
94975270 | 3354 | i.e. via menu entries of the form `(menu-item "--")'. |
9317e499 | 3355 | |
00fe2df1 JL |
3356 | ** Image API |
3357 | ||
18af70d0 CY |
3358 | *** Animated images support (currently animated gifs only). |
3359 | ||
3360 | **** `image-animated-p' returns non-nil if an image can be animated. | |
3361 | ||
3362 | **** `image-animate' animates a supplied image spec. | |
3363 | ||
3364 | **** `image-animate-timer' returns the timer object for an image that | |
3365 | is being animated. | |
00fe2df1 | 3366 | |
7cb76fe0 GM |
3367 | *** `image-extension-data' has been renamed to `image-metadata'. |
3368 | The old name is an obsolete alias to the new one. | |
1546c559 | 3369 | |
b4ac6e8c GM |
3370 | *** Image mode can view any image type that ImageMagick supports. |
3371 | This requires Emacs to be built with ImageMagick support. | |
7d301ae6 CY |
3372 | |
3373 | **** New function `imagemagick-types', defined if ImageMagick support | |
3374 | is enabled, returns a list of image file extensions that your | |
3375 | ImageMagick installation supports. | |
3376 | ||
3377 | **** New function `imagemagick-register-types' enables ImageMagick | |
3378 | image types in Image mode and in `create-image' and other helper | |
3379 | functions. | |
3380 | ||
3381 | **** New option `imagemagick-types-inhibit' excludes certain | |
3382 | ImageMagick image types from `imagemagick-register-types'. | |
3383 | ||
7d301ae6 CY |
3384 | **** With ImageMagick support, there are extra Image mode commands to |
3385 | resize and rotate images: `image-transform-fit-to-height', | |
3386 | `image-transform-fit-to-width', `image-transform-set-rotation', and | |
3387 | `image-transform-set-scale'. | |
041d709f | 3388 | |
7d301ae6 CY |
3389 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
3390 | passes it to the mail user agent function. This argument specifies an | |
3391 | action for returning to the caller after finishing with the mail. For | |
3392 | example, this is used by Rmail to optionally delete a mail window. | |
b4ac6e8c | 3393 | |
71c17aec | 3394 | ** XML and HTML parsing |
483ab230 CY |
3395 | If Emacs is compiled with libxml2 support, there are two new |
3396 | functions: `libxml-parse-html-region' (which parses "real world" HTML) | |
3397 | and `libxml-parse-xml-region' (which parses XML). Both return an | |
3398 | Emacs Lisp parse tree. | |
4b9832a6 | 3399 | |
7d301ae6 | 3400 | ** Networking and encryption changes |
e2574f2c | 3401 | |
7d301ae6 CY |
3402 | *** `open-network-stream' can now be used to open an encrypted stream. |
3403 | It now accepts an optional `:type' parameter for initiating a TLS | |
3404 | connection, directly or via STARTTLS. To do STARTTLS, additional | |
3405 | parameters (`:end-of-command', `:success', `:capabilities-command') | |
3406 | must also be supplied. | |
3407 | ||
3408 | *** New library gnutls.el. | |
dfdb4cad CY |
3409 | The new function `gnutls-available-p' returns non-nil if Emacs is |
3410 | built with GnuTLS support. The main entry points are | |
3411 | `open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use | |
3412 | these functions through `open-network-stream', because that can | |
7d301ae6 CY |
3413 | upgrade connections through STARTTLS opportunistically or use plain |
3414 | SSL, depending on your needs. For debugging, set `gnutls-log-level' | |
3415 | greater than 0. | |
3416 | ||
7d301ae6 CY |
3417 | *** New primitive `secure-hash' that supports many secure hash algorithms: |
3418 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library | |
3419 | sha1.el has been removed. The `sha1' feature is provided by default. | |
71c17aec | 3420 | |
a6020335 MH |
3421 | ** Isearch |
3422 | ||
3423 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | |
3424 | ||
9326ba26 CY |
3425 | ** Progress reporters can now "spin". |
3426 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
3427 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
3428 | time you call `progress-reporter-update' on that progress reporter, | |
3429 | with a nil or omitted VALUE argument, the reporter message is | |
3430 | displayed with a "spinning bar". | |
3431 | ||
3e214b50 JB |
3432 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is |
3433 | being reverted, even if the buffer has a local `revert-buffer-function'. | |
3434 | ||
001bf877 GM |
3435 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. |
3436 | If delayed-warnings-list is non-nil, the command loop calls | |
7d301ae6 CY |
3437 | `delayed-warnings-hook' after `post-command-hook'. At present, this |
3438 | is only used by Emacs on some platforms to display warnings during | |
3439 | startup, which might otherwise not be noticed. This uses the | |
3440 | functions `display-delayed-warnings' and `collapse-delayed-warnings'. | |
001bf877 | 3441 | |
6420d28b CY |
3442 | ** rx.el has a new `group-n' construct for explicitly numbered groups. |
3443 | ||
dac86404 GM |
3444 | ** New function `make-composed-keymap' that constructs a new keymap |
3445 | from multiple input maps. You can use this to make a keymap that | |
3446 | inherits from multiple maps, eg: | |
3447 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) | |
43dc9f5b | 3448 | |
c8f6ec5c GM |
3449 | ** New function `string-prefix-p'. |
3450 | (This was actually added in Emacs 23.2 but was not advertised at the time.) | |
3451 | ||
27f7ef2f | 3452 | ** New reader macro ## that stands for the empty symbol. |
43dc9f5b AS |
3453 | This means that the empty symbol can now be read back. Also, #: by itself |
3454 | (when not immediately followed by a possible symbol character) stands for | |
3455 | an empty uninterned symbol. | |
041d709f | 3456 | |
fead402d CY |
3457 | ** New math functions `isnan', `copysign', `frexp', `ldexp'. |
3458 | ||
7d301ae6 | 3459 | ** The following functions and variables are obsolete: |
041d709f | 3460 | |
05f77e38 GM |
3461 | *** `tooltip-use-echo-area' is obsolete. |
3462 | Rather than setting this to t, disable Tooltip mode instead. | |
3463 | ||
041d709f CY |
3464 | *** buffer-substring-filters is obsolete. |
3465 | Use `filter-buffer-substring-functions' instead. | |
3466 | ||
3467 | *** `byte-compile-disable-print-circle' is obsolete. | |
3468 | ||
3469 | *** `deferred-action-list' and `deferred-action-function' are obsolete. | |
f160676e GM |
3470 | Use `post-command-hook' instead. |
3471 | ||
67e729a5 CY |
3472 | *** `font-lock-maximum-size' is obsolete. |
3473 | ||
eb199145 | 3474 | \f |
93e0bed6 | 3475 | * Changes in Emacs 24.1 on Non-Free Operating Systems |
d53a60a6 | 3476 | |
7a22e700 | 3477 | ** On MS Windows, Emacs warns when using the obsolete init file _emacs, |
a2f0118c GM |
3478 | and also when HOME is set to C:\ by default. |
3479 | ||
7a22e700 | 3480 | ** New configure.bat options |
04779484 | 3481 | |
7a22e700 | 3482 | *** --enable-checking builds Emacs with extra runtime checks. |
e3aef5c6 | 3483 | |
7a22e700 | 3484 | *** --distfiles specifies files to be included in binary distribution. |
e2574f2c | 3485 | |
7a22e700 OK |
3486 | *** --without-gnutls disables automatic GnuTLS detection. |
3487 | ||
a0d363f4 | 3488 | *** --lib for general library linkage, works with the USER_LIBS build variable. |
e2574f2c | 3489 | |
0a19a6f8 | 3490 | ** New make target `dist' to create binary distribution for MS Windows. |
e3aef5c6 | 3491 | |
1f5e1a16 GM |
3492 | ** The Lisp function `w32-default-color-map' is now obsolete. |
3493 | (It is only used internally in the Emacs C code.) | |
5430d399 | 3494 | |
1f5e1a16 GM |
3495 | ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but |
3496 | reappear on mouse-over. (Requires OS X 10.6 or later.) | |
04e2ce72 | 3497 | |
ad7c802c CY |
3498 | ** On Mac OS X, dragging a file into Emacs visits the file, like on |
3499 | other platforms, rather than inserting its contents into the buffer. | |
