18 | +++ indicates that all necessary documentation updates are complete. |
19 | (This means all relevant manuals in doc/ AND lisp doc-strings.) | |
219afb88 | 20 | --- means no change in the manuals is needed. |
d856c4a9 | 21 | When you add a new item, use the appropriate mark if you are sure it applies, |
219afb88 | 22 | otherwise leave it unmarked. |

32 | ** By default, Emacs no longer works on IRIX. We expect that Emacs |
33 | users are not affected by this, as SGI stopped supporting IRIX in | |
34 | December 2013. If you are affected, please send a bug report. You | |
35 | should be able to work around the problem either by porting the Emacs | |
36 | undumping code to GCC under IRIX, or by configuring --with-wide-int, | |
37 | or by sticking with Emacs 24.4. | |

68 | * Editing Changes in Emacs 24.5 | |
69 | ||
bfc30790 DC |
70 | Emacs now supports "bracketed paste mode" when running on a terminal |
71 | that supports it. This facility allows Emacs to understand pasted | |
72 | chunks of text as strings to be inserted instead of interpreting each | |
73 | character in the pasted text as actual user input, resulting in a | |
74 | paste experience similar to that under a window system and significant | |
75 | performance improvements when pasting large amounts of text. | |

78 | * Changes in Specialized Modes and Packages in Emacs 24.5 | |
79 | ||
6711a21f SM |
80 | ** font-lock |
81 | *** New functions font-lock-ensure and font-lock-flush that should be used | |
82 | instead of font-lock-fontify-buffer when called from Elisp. | |
83 | ||
664ed753 RS |
84 | --- |
85 | ** The Rmail commands d, C-d and u now handle repeat counts | |
86 | to delete or undelete multiple messages. | |
5076d275 | 87 | |
bbdcf64f LL |
88 | ** Calendar and diary |
89 | ||
90 | +++ | |
91 | *** New commands to insert diary entries with Chinese dates: | |
92 | `diary-chinese-insert-anniversary-entry' `diary-chinese-insert-entry' | |
93 | `diary-chinese-insert-monthly-entry' | |
94 | `diary-chinese-insert-yearly-entry' | |
95 | ||
96 | +++ | |
f930a063 | 97 | *** Calendar can list and mark diary entries with Chinese dates: |
bbdcf64f LL |
98 | `diary-chinese-list-entries' and `diary-chinese-mark-entries'. |
99 | ||
deb37a7f GM |
100 | ** In sh-mode, you can now use `sh-shell' as a file-local variable to |
101 | specify the type of shell in use (bash, csh, etc). | |
102 | ||
20253ce1 MA |
103 | ** The URL package accepts now the protocols "ssh", "scp" and "rsync". |
104 | When `url-handler-mode' is enabled, file operations for these | |
105 | protocols as well as for "telnet" and "ftp" are passed to Tramp. | |
106 | ||
b4aca021 GM |
107 | ** Obsolete packages |
108 | ||

2be772ff EZ |
135 | +++ |
136 | ** Mouse click events on mode line or header line no longer include | |
137 | any reference to a buffer position. The 6th member of the mouse | |
138 | position list returned for such events is now nil. | |

142 | * Lisp Changes in Emacs 24.5 | |
143 | ||
0e4857b7 SM |
144 | ** New function `funcall-interactively', which works like `funcall' |
145 | but makes `called-interactively-p' treat the function as (you guessed it) | |
146 | called interactively. | |
147 | ||
67c477ae SM |
148 | ** New function `function-put' to use instead of `put' for function properties. |
149 | ||
5076d275 | 150 | +++ |
67c477ae SM |
151 | ** New properties that can be specified with `declare': |
152 | *** (interactive-only INSTEAD), tells to use INSTEAD for non-interactive use. | |
153 | *** (pure VAL), if VAL is non-nil, indicates the function is pure. | |
154 | *** (side-effect-free VAL), if VAL is non-nil, indicates the function does not | |
155 | have side effects. | |
5076d275 | 156 | |
d63d883a GM |
157 | +++ |
158 | ** New macro `with-file-modes', for evaluating expressions with default file | |
159 | permissions set to temporary values (e.g., for creating private files). | |
160 | ||
d6f14ca7 | 161 | ** You can access the slots of structures using `cl-struct-slot-value'. |
89a2e783 | 162 | |
e50e0340 KO |
163 | ** Functions `rmail-delete-forward' and `rmail-delete-backward' take an |

95a32efb | 170 | * Installation Changes in Emacs 24.4 |
7c3d167f | 171 | |
3eacddfe | 172 | ** Emacs can now be compiled with ACL (access control list) support. |
7c3d167f RF |
173 | This happens by default if a suitable support library is found at |
174 | build time, like libacl on GNU/Linux. To prevent this, use the | |
3eacddfe | 175 | configure option `--disable-acl'. See below for the features this provides. |
7c3d167f | 176 | |
70c8f5ca | 177 | ** Emacs can now be compiled with file notification support. |
671d4bfc GM |
178 | This happens by default if a suitable system library is found at |
179 | build time. To prevent this, use the configure option | |
e873a22e | 180 | `--without-file-notification'. See below for file-notify features. |
81a15753 GM |
181 | This feature is not available for the Nextstep port. |
182 | ||
81a15753 GM |
183 | ** Emacs can now be compiled with zlib support. |
184 | This happens by default if zlib is present, which it normally is. | |
185 | To prevent this, use the configure option `--without-zlib'. | |
186 | This provides the function `zlib-decompress-region'; see below for details. | |
2f23b3ab | 187 | |
70c8f5ca CY |
188 | ** The configure option `--without-compress-info' has been generalized, |
189 | and renamed to `--without-compress-install'. It now prevents compression | |
335142f9 GM |
190 | of _any_ files during installation. |
191 | ||
70c8f5ca | 192 | ** The configure option `--with-crt-dir' has been removed. |
a22359a7 | 193 | It is no longer needed, as the crt*.o files are no longer linked specially. |
f1e496a5 | 194 | |
ae7bfbf5 JB |
195 | ** Directories passed to configure option `--enable-locallisppath' are |
196 | no longer created during installation. | |
197 | ||
3eacddfe | 198 | ** Emacs for Nextstep (Mac OS X, GNUstep) can be built with ImageMagick support. |
81a15753 | 199 | This requires pkg-config to be available at build time. |

95a32efb | 202 | * Startup Changes in Emacs 24.4 |
c57b2d76 | 203 | |
17e0445b GM |
204 | ** When initializing `load-path', an empty element in the EMACSLOADPATH |
205 | environment variable (either leading, e.g., ":/foo"; trailing, e.g., | |
206 | "/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default | |
207 | load-path (the one that would have been used if EMACSLOADPATH was unset). | |
208 | This makes it easier to _extend_ the load-path via EMACSLOADPATH | |
209 | (previously, EMACSLOADPATH had to specify the complete load-path, | |
210 | including the defaults). (In older versions of Emacs, an empty element | |
211 | was replaced by ".", so use an explicit "." now if that is what you want.) | |
212 | ||
a0833f62 | 213 | ** The -L option, which normally prepends its argument to load-path, |
2df10228 GM |
214 | will instead append, if the argument begins with `:' (or `;' on MS Windows; |
215 | i.e., `path-separator'). | |
a0833f62 | 216 | |
06a4f110 GM |
217 | ** If you use either site-load.el or site-init.el to customize the dumped |
218 | Emacs executable, any changes to `load-path' that these files make | |
219 | will no longer be present after dumping. To affect a permanent change | |
220 | to `load-path', use the `--enable-locallisppath' option of `configure'. | |
221 | ||
70c8f5ca CY |
222 | ** The user option `initial-buffer-choice' can now specify a function |
223 | to set up the initial buffer. | |
224 | ||
c57b2d76 | 225 | \f |
95a32efb | 226 | * Changes in Emacs 24.4 |
c6c08d3f | 227 | |
3eacddfe GM |
228 | ** Support for ACLs (access control lists). |
229 | This requires a suitable support library to be found at build time. | |
230 | On GNU/Linux, the POSIX ACL interface is used via libacl. | |
231 | On MS-Windows, the NT Security APIs are used to emulate the POSIX interface. | |
232 | ACLs are extended file attributes, used e.g. for finer-grained permissions. | |
81a15753 | 233 | |
3eacddfe | 234 | *** Emacs preserves the ACL entries of files when backing up. |
d8a2993d | 235 | |
3eacddfe GM |
236 | *** New functions `file-acl' and `set-file-acl' get and set file ACLs. |
237 | ||
238 | ** Support for menus on text-mode terminals. | |
0a12fca0 EZ |
239 | If the terminal supports a mouse, clicking on the menu bar, or on |
240 | sensitive portions of the mode line or header line, will drop down the | |
3eacddfe GM |
241 | menu defined at that position. Likewise, clicking C-mouse-1, C-mouse-2, or |
242 | C-mouse-3 on the text area will pop up the menus defined for those locations. | |
0a12fca0 EZ |
243 | |
244 | If the text terminal does not support a mouse, you can activate the | |
245 | first menu-bar menu by typing F10, which invokes `menu-bar-open'. | |
246 | ||
3eacddfe | 247 | If you want the previous behavior, where F10 invoked `tmm-menubar', |
0a12fca0 | 248 | customize the option `tty-menu-open-use-tmm' to a non-nil value. |
f8b18150 GM |
249 | (Typing M-` always invokes `tmm-menubar', even if `tty-menu-open-use-tmm' |
250 | is nil.) | |
0a12fca0 | 251 | |
3eacddfe GM |
252 | ** New option `load-prefer-newer' affects how the `load' function chooses |
253 | the file to load. If this is non-nil, then when both .el and .elc | |
254 | versions of a file exist, and the caller did not explicitly specify | |
255 | which one to load, then the newer file is loaded. The default, nil, | |
256 | means to always load the .elc file. | |
7c3d167f | 257 | |
3eacddfe | 258 | ** Multi-monitor support |
4e3f9230 YM |
259 | |
260 | *** New functions `display-monitor-attributes-list' and | |
261 | `frame-monitor-attributes' can be used to obtain information about | |
262 | each physical monitor on multi-monitor setups. | |
263 | ||
cf13177e YM |
264 | *** The functions `display-pixel-width' and `display-pixel-height' now |
265 | behave consistently among the platforms: they return the pixel width | |
266 | or height for all physical monitors associated with the given display | |
7ebd57e9 | 267 | as if they were on X. To get information for each physical |
cf13177e YM |
268 | monitor, use the new functions above. Similar notes also apply to |
269 | `x-display-pixel-width', `x-display-pixel-height', `display-mm-width', | |
270 | `display-mm-height', `x-display-mm-width', and `x-display-mm-height'. | |
271 | ||
3eacddfe GM |
272 | ** New function `zlib-decompress-region', which decompresses gzip- and |
273 | zlib-format compressed data using built-in zlib support (if available). | |
274 | ||
275 | ** The *Messages* buffer is created in `messages-buffer-mode', | |
276 | a new major mode, with read-only status. Any code that might create | |
277 | the *Messages* buffer should call the function `messages-buffer' to do | |
278 | so and set up the mode. | |
279 | ||
280 | ** The cursor stops blinking after 10 blinks (by default) on X and Nextstep. | |
70c8f5ca | 281 | You can change the default by customizing `blink-cursor-blinks'. |
61e56e2c | 282 | |
70c8f5ca CY |
283 | ** In keymaps where SPC scrolls forward, S-SPC now scrolls backward. |
284 | This affects View mode, etc. | |
285 | ||
b54b4b12 | 286 | ** The default value of `make-backup-file-name-function' is no longer nil. |
d60a0a17 GM |
287 | Instead it defaults to a function that does what the nil value used to. |
288 | ||
3eacddfe | 289 | ** Help |
f88ac3bb | 290 | |
70c8f5ca | 291 | *** The command `apropos-variable' is renamed to `apropos-user-option'. |
3eacddfe | 292 | `apropos-user-option' shows all user options, while `apropos-variable' |
70c8f5ca CY |
293 | shows all variables. When called with a universal prefix argument, |
294 | the two commands swap their behaviors. When `apropos-do-all' is | |
295 | non-nil, they output the same results. | |
18c26d81 | 296 | |
70c8f5ca | 297 | *** The key `?' now describes prefix bindings, like `C-h'. |
6585d561 | 298 | |
8251c3f8 | 299 | *** The command `describe-function' has been extended for EIEIO. |
3ca34b22 | 300 | Running it on constructors will show a full description of the |
d6a62260 | 301 | generated class. For generic functions, it will show all |
3ca34b22 DE |
302 | implementations together with links to the source. The old commands |
303 | `describe-class', `describe-constructor' and `describe-generic' were | |
304 | removed. | |
305 | ||
44e76f9d | 306 | *** The function `quail-help' is no longer an interactive command. |
8251c3f8 | 307 | Use `C-h C-\' (`describe-input-method') instead. |
6950f152 | 308 | |
b29daf07 GM |
309 | ** ImageMagick |
310 | ||
8251c3f8 | 311 | *** ImageMagick images now support the :max-width and :max-height keywords. |
b29daf07 | 312 | |
7b997b14 GM |
313 | *** When using `create-image' with image data, you can pass a :format |
314 | attribute (via the property-list argument) in order to help | |
315 | ImageMagick detect the image type. The value should be a MIME | |
316 | content-type that is found in the new variable `image-format-suffixes'. | |
b29daf07 | 317 | |
70c8f5ca | 318 | ** Frame and window changes |
da9ea6d9 | 319 | |
70c8f5ca CY |
320 | *** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized', |
321 | bound to <f11> and M-<f10>, respectively. | |
0a749fa0 | 322 | |
70c8f5ca CY |
323 | *** New hooks `focus-in-hook', `focus-out-hook'. |
324 | These are normal hooks run when an Emacs frame gains or loses input focus. | |
325 | ||
3eacddfe GM |
326 | *** The function `window-in-direction' now takes additional arguments |
327 | for specifying a reference point, wrapping the selection around frame | |
328 | borders, and specifying ways to select the minibuffer window. | |
329 | ||
ca58fa73 GM |
330 | *** Emacs can now change frame sizes in units of pixels, rather than |
331 | text rows or columns. When maximizing a frame or making it fullscreen, | |
332 | remaining extra pixels are no longer given to the minibuffer, the rightmost | |
333 | fringe, or other unusable space, but are distributed among the text | |
334 | areas of the frame's windows. If the new option `frame-resize-pixelwise' | |
335 | is non-nil, all frame size changes happen pixelwise and set the | |
336 | corresponding size hints for the window manager. | |
337 | ||
338 | *** Emacs can now change window sizes in units of pixels. | |
339 | Mouse-dragging a mode line or window divider now changes the size of | |
340 | adjacent windows pixelwise. If the new option `window-resize-pixelwise' | |
341 | is non-nil, functions like `balance-windows-area' and `fit-window-to-buffer' | |
342 | resize windows pixelwise. Most functions for changing or accessing | |
343 | window sizes now have an additional argument that allows changes to apply, | |
344 | or values to be returned, in pixels instead of lines/columns. | |
b7aa5ad6 | 345 | |
cac0a1d6 MR |
346 | *** The functions `window-body-height' and `window-body-width' now never |
347 | count partially visible lines or columns if called with a nil PIXELWISE | |
348 | argument. | |
349 | ||
b7aa5ad6 MR |
350 | *** Emacs can now draw dividers between adjacent windows. To put |
351 | dividers between side-by-side/vertically stacked windows customize the | |
352 | frame parameters `right-divider-width' and `bottom-divider-width' to | |
353 | some positive integer. You can drag dividers with the mouse (they show | |
354 | a corresponding cursor when the mouse hovers over them). You can change | |
355 | the appearance of dividers by customizing the faces `window-divider', | |
356 | `window-divider-first-pixel', and `window-divider-last-pixel'. The last | |
357 | two are useful to provide a 3D effect, or to better distinguish dividers | |
358 | from surrounding display objects. | |
359 | ||
3eacddfe GM |
360 | *** New functions to return the pixel sizes of window components, namely |
361 | `window-scroll-bar-width', `window-mode-line-height', | |
362 | `window-header-line-height', `window-right-divider-width', and | |
b7aa5ad6 MR |
363 | `window-bottom-divider-width'. |
364 | ||
b7aa5ad6 MR |
365 | *** The new function `window-text-pixel-size' returns the size of the |
366 | text of a window's buffer in pixels. This allows functions like | |
367 | `fit-frame-to-buffer' and `fit-window-to-buffer' to accurately fit a | |
368 | window to its buffer as it will be displayed. | |

cac0a1d6 | 370 | *** `fit-window-to-buffer' can now resize windows in both dimensions. |
b7aa5ad6 | 371 | This behavior is controlled by the new option |
cac0a1d6 | 372 | `fit-window-to-buffer-horizontally'. The new option |
3eacddfe | 373 | `fit-frame-to-buffer' allows you to fit the window's frame to its buffer. |
b7aa5ad6 | 374 | |
cac0a1d6 MR |
375 | *** `fit-frame-to-buffer' now fits frames in both dimensions. The new |
376 | options `fit-frame-to-buffer-margins' and `fit-frame-to-buffer-sizes' | |
b7aa5ad6 MR |
377 | control the size of the frame and its position on screen. |
378 | ||
3eacddfe GM |
379 | *** Temp Buffer Resize Mode can now adjust the height and width of |
380 | windows and frames. The new option `temp-buffer-max-width' allows you to | |
381 | control the width of temporary buffer windows. Moreover, if the new | |
382 | option `fit-frame-to-buffer' is non-nil and the buffer appears in the | |
383 | root window of a frame, Temp Buffer Resize Mode will try to adjust the | |
384 | width and/or height of the frame. | |
764ec9e5 | 385 | |
70c8f5ca CY |
386 | *** `split-window' is now a non-interactive function, not a command. |
387 | As a command, it was a special case of `C-x 2' (`split-window-below'), | |
388 | and as such superfluous. After being reimplemented in Lisp, its | |
389 | interactive form was mistakenly retained. | |
4f0552c2 | 390 | |
b7aa5ad6 MR |
391 | *** The functions `window-size' and `window-total-size' now have an |
392 | optional argument to return a rounded size value. | |
393 | ||
3eacddfe | 394 | *** `window-state-put' now allows you to put a window state into internal |
b7aa5ad6 MR |
395 | windows too. |
396 | ||
70c8f5ca | 397 | *** New option `scroll-bar-adjust-thumb-portion'. |
3eacddfe GM |
398 | Available only on X, this option allows you to control over-scrolling |
399 | using the scroll bar (i.e., dragging the thumb down even when the end | |
70c8f5ca CY |
400 | of the buffer is visible). |
401 | ||
3eacddfe | 402 | *** New display actions functions for `display-buffer': |
b7aa5ad6 | 403 | |
3eacddfe GM |
404 | **** `display-buffer-in-previous-window' displays a buffer in a window |
405 | previously showing that buffer. | |
b7aa5ad6 | 406 | |
3eacddfe GM |
407 | **** `display-buffer-at-bottom' chooses or creates a window at the |
408 | bottom of the selected frame. | |
b7aa5ad6 | 409 | |
3eacddfe | 410 | **** `display-buffer-no-window' to not display the buffer in a window. |
ecc384ac XF |
411 | |
412 | *** New display action alist entry `allow-no-window' to indicate the | |
3eacddfe GM |
413 | caller of `display-buffer' is ready to handle the case of not displaying |
414 | the buffer in a window. | |
ecc384ac | 415 | |
70c8f5ca | 416 | ** Lisp evaluation changes |
3eacddfe | 417 | |
70c8f5ca CY |
418 | *** `eval-defun' on an already defined defcustom calls the :set function, |
419 | if there is one. | |
420 | ||
d856c4a9 | 421 | *** The commands `eval-expression' (`M-:'), `eval-last-sexp' (`C-x C-e'), |
c51e81ef GM |
422 | and `eval-print-last-sexp' (`C-j' in Lisp Interaction mode) can take a |
423 | zero prefix argument. This disables truncation of lists in the output, | |
424 | equivalent to setting `(eval-expression-)print-length' and | |
4d000e69 | 425 | `(eval-expression-)print-level' to nil. Additionally, it causes integers |
c51e81ef | 426 | to be printed in other formats (octal, hexadecimal, and character). |
70c8f5ca | 427 | |
6bbc0c84 GM |
428 | *** New hook `eval-expression-minibuffer-setup-hook' run by |
429 | `eval-expression' on entering the minibuffer. | |
430 | ||
314ffdb1 | 431 | ** `cache-long-line-scans' is now non-nil, and renamed to `cache-long-scans', |
70c8f5ca | 432 | because it affects caching of paragraph scanning results as well. |
314ffdb1 | 433 | There is no reason to set this to nil except for debugging purposes. |
4e36a6a6 | 434 | |
3eacddfe GM |
435 | ** `emacs-bzr-version' has been renamed to `emacs-repository-version', |
436 | and works for git too, if you fetch the repository notes. | |
70c8f5ca | 437 | |
8251c3f8 | 438 | ** The default value of `comment-use-global-state' is now t, |
70c8f5ca CY |
439 | and this variable has been marked obsolete. |
440 | ||
3eacddfe | 441 | ** `write-region-inhibit-fsync' now defaults to t in batch mode. |
8251c3f8 | 442 | |
3eacddfe GM |
443 | ** The option `set-mark-default-inactive' has been deleted. |
444 | This unfinished feature was introduced by accident in Emacs 23.1; | |
445 | simply disabling Transient Mark mode does the same thing. | |
642d7ae8 | 446 | |

448 | * Editing Changes in Emacs 24.4 | |
449 | ||
450 | ** Indentation changes | |
451 | ||
03bc753e | 452 | *** `electric-indent-mode' is now enabled by default. |
95de732d GM |
453 | Typing RET reindents the current line and indents the new line. |
454 | `C-j' inserts a newline but does not indent. In some programming modes, | |
455 | additional characters are electric (eg `{'). | |
03bc753e | 456 | |
5b7853e3 GM |
457 | *** New buffer-local `electric-indent-local-mode'. |
458 | ||
70c8f5ca CY |
459 | *** The behavior of `C-x TAB' (`indent-rigidly') has changed. |
460 | When invoked without a prefix argument, it now activates a transient | |
461 | mode in which typing <left>, <right>, <S-left>, and <S-right> adjusts | |
462 | the text indentation in the region. Typing any other key resumes | |
463 | normal editing behavior. | |
3472b6c6 | 464 | |
70c8f5ca | 465 | *** `tab-stop-list' is now implicitly extended to infinity by repeating |
8251c3f8 | 466 | the last step. Its default value is changed to nil, which means a tab |
3ccc2d28 | 467 | stop every `tab-width' columns. |
b7d5bd82 | 468 | |
8251c3f8 | 469 | ** Uniquify is enabled by default, with `post-forward-angle-brackets' style. |
99d8aedf GM |
470 | In other words, if you visit two files that have the same base name, |
471 | then rather than creating buffers basename and basename<2>, | |
472 | Emacs uses basename<dirA> and basename<dirB>. To change this, | |
473 | customize `uniquify-buffer-name-style'. Set it to nil for the old behavior. | |
70c8f5ca CY |
474 | |
475 | ** New command `C-x SPC' (`rectangle-mark-mode') makes a rectangular region. | |
476 | Most commands are still unaware of it, but kill/yank do work on the rectangle. | |
958614cf | 477 | |
4c672a0f EZ |
478 | ** New option `visual-order-cursor-movement'. |
479 | If this is non-nil, cursor motion with arrow keys will follow the | |
480 | visual order of characters on the screen: <left> always moves to the | |
481 | left, <right> always moves to the right, disregarding the surrounding | |
482 | bidirectional context. | |
483 | ||
3eacddfe GM |
484 | ** New command `delete-duplicate-lines'. |
485 | This searches the region for identical lines, and removes all but one | |
486 | copy of each repeated line. The lines need not be sorted. | |
487 | ||
488 | ** New command `cycle-spacing' acts like a smarter `just-one-space'. | |
489 | When called in succession, it cycles between spacing conventions: | |
490 | one space, no spaces, original spacing. | |
491 | ||
492 | ** `blink-matching-paren' now only highlights the matching open-paren | |
493 | by default, instead of moving the cursor. Set this variable to `jump' to | |
494 | restore the old behavior. | |
495 | ||
496 | ** The new function `fill-single-char-nobreak-p' can stop fill from breaking | |
497 | a line after a one-letter word, which is an error in some typographical | |
498 | conventions. To use it, add it to the `fill-nobreak-predicate' hook. | |
499 | ||
500 | ** Registers | |
c8af480d | 501 | |
da942af1 GM |
502 | *** All interactive commands that read a register (`copy-to-register', etc.) |
503 | now display a temporary window after `register-preview-delay' seconds | |
504 | that summarizes existing registers. To disable this, set that option to nil. | |
eb9b8ff6 GM |
505 | Interactive commands that read registers and want to make use of this |
506 | should use `register-read-with-preview' to read register names. | |
0b1619da | 507 | |
68a8b28f GM |
508 | *** New command `frameset-to-register' bound to `C-x r f', replacing |
509 | `frame-configuration-to-register'. It offers similar functionality, | |
510 | plus enhancements like the ability to restore deleted frames. | |
511 | (`frame-configuration-to-register' still exists, but no longer has a | |
512 | key binding.) | |
513 | ||
ced5cc29 XF |
514 | *** New command `C-x C-k x' (`kmacro-to-register') stores keyboard |
515 | macros in registers. | |
ac2f8659 | 516 | |
4f0552c2 | 517 | \f |
95a32efb | 518 | * Changes in Specialized Modes and Packages in Emacs 24.4 |
4f0552c2 | 519 | |
70c8f5ca | 520 | ** Backtrace and debugger |
e56221d5 | 521 | |
47a73eb0 | 522 | *** New Lisp debugger command `v' (`debugger-toggle-locals') toggles the |
ace97938 | 523 | display of local variables of the current stack frame. |
47a73eb0 GM |
524 | |
525 | *** The Lisp debugger's `e' command (`debugger-eval-expression') now includes | |
526 | the lexical environment when evaluating the code in the context at point | |
527 | (and so allows you to access lexical variables). | |
b14abca9 | 528 | |
47a73eb0 | 529 | *** New minor mode `jit-lock-debug-mode' helps you debug code run via JIT Lock. |
4b72c12b | 530 | |
ece4bae5 | 531 | ** Battery information can now be retrieved from BSD's `apm' utility. |
19b748ad | 532 | |
ece4bae5 | 533 | ** In the Buffer Menu, `M-s a C-o' shows matches for a regexp in marked buffers. |
96673afe | 534 | |
0e70ce93 PE |
535 | ** Calc |
536 | ||
537 | *** Calc by default now uses the Gregorian calendar for all dates, and | |
538 | uses January 1, 1 AD as its day number 1. Previously Calc used the | |
539 | Julian calendar for dates before September 14, 1752, and it used | |
540 | December 31, 1 BC as its day number 1; the new scheme is more | |
541 | consistent with Calendar's calendrical system and day numbering. | |
542 | ||
68d01ccc GM |
543 | *** The new option `calc-gregorian-switch' lets you configure if |
544 | (and when) Calc switches from the Julian to the Gregorian calendar. | |
0e70ce93 | 545 | |
86e100a6 GM |
546 | *** Support for ISO 8601 dates. |
547 | ||
3eacddfe GM |
548 | ** Calendar and Diary |
549 | ||
550 | *** New faces `calendar-weekday-header', `calendar-weekend-header', | |
551 | and `calendar-month-header'. | |
552 | ||
553 | *** New option `calendar-day-header-array'. | |
554 | ||
555 | *** New variable `diary-from-outlook-function', used by the command | |
556 | `diary-from-outlook'. | |
557 | ||
558 | *** The variable `calendar-font-lock-keywords' is obsolete. | |
559 | ||
70c8f5ca CY |
560 | ** CEDET |
561 | ||
562 | *** EDE | |
563 | ||
564 | **** The cpp-root project now supports executing a compile command. | |
565 | It can be set through the new :compile-command slot or the | |
566 | buffer-local variable `compile-command'. | |
567 | ||
568 | **** Better selection of include directories for the 'linux' project. | |
569 | Include directories now support out-of-tree build directories and | |
570 | target architecture auto-detection. | |
571 | ||
572 | *** Semantic | |
573 | ||
574 | **** Improved detection of used namespaces in current scope in C++. | |
575 | ||
576 | **** Parsing of default values for variables and function arguments in C/C++. | |
a22359a7 | 577 | They are also displayed by the summarize feature in the mode line. |
70c8f5ca CY |
578 | |
579 | **** Improved parsing of function pointers in C/C++. | |
580 | This also includes parsing of function pointers as function arguments. | |
581 | ||
a22359a7 GM |
582 | **** Parsing of C/C++ preprocessor macros that open new scope. |
583 | For example, this enables parsing of macros that open new namespaces. | |
70c8f5ca CY |
584 | |
585 | **** Support for 'this' pointer in inline member functions in C++. | |
586 | ||
3eacddfe GM |
587 | ** CFEngine mode |
588 | ||
589 | *** Support for completion, ElDoc, and Flycheck has been added. | |
590 | ||
591 | *** The current CFEngine syntax is parsed from "cf-promises -s json". | |
592 | There is a fallback syntax available if you don't have cf-promises or | |
593 | if your version doesn't support that option. See option `cfengine-cf-promises'. | |
594 | ||
70c8f5ca CY |
595 | ** cl-lib |
596 | ||
8d3c54a0 | 597 | *** New macro `cl-tagbody'. |
f16a3d52 | 598 | This executes statements while allowing for control transfer to labels. |
70c8f5ca | 599 | |
70c8f5ca CY |
600 | *** letf is now just an alias for cl-letf. |
601 | ||
602 | ** CUA mode | |
603 | ||
642d7ae8 | 604 | *** CUA mode now uses `delete-selection-mode' and `shift-select-mode'. |
5ad1fede GM |
605 | Hence, you can now enable it independently from those modes, and from |
606 | `transient-mark-mode'. | |
642d7ae8 CY |
607 | |
608 | *** `cua-highlight-region-shift-only' is now obsolete. | |
609 | You can disable `transient-mark-mode' to get the same result. | |
70c8f5ca | 610 | |
6faf982a SM |
611 | *** CUA's rectangles can now be used without CUA by calling the command |
612 | `cua-rectangle-mark-mode'. | |
70c8f5ca | 613 | |
a69ecd19 | 614 | ** Delete Selection mode can now be used without Transient Mark mode. |
70c8f5ca | 615 | |
5db9dace JL |
616 | ** Desktop |
617 | ||
c863b6ad GM |
618 | *** `desktop-save-mode' by default now auto-saves an existing desktop file |
619 | after `desktop-auto-save-timeout'. To disable this, customize that option | |
620 | to nil (or zero). | |
5db9dace | 621 | |
46456005 GM |
622 | *** Desktop now saves and restores the frame/window configuration. |
623 | To disable this, set `desktop-restore-frames' to nil. | |
624 | See also related options `desktop-restore-reuses-frames', | |
625 | `desktop-restore-in-current-display', and `desktop-restore-forces-onscreen'. | |
39c0e36f | 626 | |
52695556 | 627 | ** New Dired minor mode `dired-hide-details-mode' toggles whether details, |
0c483238 EZ |
628 | such as file ownership or permissions, are visible in Dired buffers. |
629 | See the new options `dired-hide-details-hide-symlink-targets' and | |
630 | `dired-hide-details-hide-information-lines' for customizing what to hide. | |
a2a538b1 | 631 | |
314ff318 GM |
632 | ** You can enable ElDoc inside the `eval-expression' minibuffer with: |
633 | (add-hook 'eval-expression-minibuffer-setup-hook 'eldoc-mode) | |
634 | The results display in the mode line. | |
21859ebc | 635 | |
3b8d5131 | 636 | ** Electric Pair mode |
3b8d5131 | 637 | |
8251c3f8 GM |
638 | *** New option `electric-pair-preserve-balance', enabled by default. |
639 | If non-nil, pairing/skipping only kicks in when that help the balance | |
3eacddfe | 640 | of parentheses and quotes; i.e., the buffer should end up at least as |
3b8d5131 JT |
641 | balanced as before. |
642 | ||
da5ecfa9 | 643 | You can further control this behavior by adjusting the predicates |
8251c3f8 | 644 | stored in `electric-pair-inhibit-predicate' and `electric-pair-skip-self'. |
3b8d5131 | 645 | |
8251c3f8 | 646 | *** New option `electric-pair-delete-adjacent-pairs', enabled by default. |
3b8d5131 JT |
647 | In `electric-pair-mode', the commands `backward-delete-char' and |
648 | `backward-delete-char-untabify' are now bound to electric variants | |
649 | that delete the closer when invoked between adjacent pairs. | |
650 | ||
8251c3f8 | 651 | *** New option `electric-pair-open-newline-between-pairs', enabled by default. |
3b8d5131 JT |
652 | In `electric-pair-mode', inserting a newline between adjacent pairs |
653 | opens an extra newline after point, which is indented if | |
654 | `electric-indent-mode' is also set. | |
655 | ||
8251c3f8 GM |
656 | *** New option `electric-pair-skip-whitespace', enabled by default. |
657 | This controls if skipping over closing delimiters should jump over any | |
658 | whitespace slack. Setting it to `chomp' makes it delete this | |
659 | whitespace. See also the variable `electric-pair-skip-whitespace-chars'. | |
3b8d5131 JT |
660 | |
661 | *** New variables control the pairing in strings and comments. | |
3b8d5131 | 662 | You can customize `electric-pair-text-pairs' and |
da5ecfa9 | 663 | `electric-pair-text-syntax-table' to tweak pairing behavior inside |
3b8d5131 JT |
664 | strings and comments. |
665 | ||
b89878d3 | 666 | ** New EPA option `epa-mail-aliases'. |
79b6e0a9 GM |
667 | You can set this to a list of email address aliases that `epa-mail-encrypt' |
668 | should use to find keys. | |
ed02dcfa | 669 | |
b89878d3 | 670 | ** New ERC option `erc-accidental-paste-threshold-seconds'. |
2040a2fe | 671 | If set to a number, this can be used to avoid accidentally pasting large |
70c8f5ca CY |
672 | amounts of data into the ERC input. |
673 | ||
8251c3f8 | 674 | ** New ERT macro `skip-unless' allows skipping ERT tests. |
70c8f5ca CY |
675 | |
676 | ** Eshell | |
677 | ||
8251c3f8 | 678 | *** `eshell' now supports visual subcommands and options. |
70c8f5ca CY |
679 | Eshell has been able to handle "visual" commands (interactive, |
680 | non-line oriented commands such as top that require display | |
681 | capabilities not provided by eshell) by running them in an Emacs | |
682 | terminal emulator. See `eshell-visual-commands'. | |
683 | ||
684 | This feature has been extended to subcommands and options that make a | |
685 | usually line-oriented command a visual command. Typical examples are | |
8251c3f8 | 686 | "git log" and "git <command> --help", which display their output in a |
3eacddfe | 687 | pager by default. See `eshell-visual-subcommands' and `eshell-visual-options'. |
70c8f5ca | 688 | |
8251c3f8 | 689 | *** New Eshell-Tramp module. |
70c8f5ca | 690 | External su and sudo commands are now the default; the internal, |
3eacddfe | 691 | Tramp-using variants can still be used by enabling the eshell-tramp module. |
70c8f5ca | 692 | |
b89878d3 | 693 | ** New F90 mode option `f90-smart-end-names'. |
70c8f5ca | 694 | |
3eacddfe GM |
695 | ** New option `gnutls-verify-error', if non-nil, means that Emacs |
696 | should reject SSL/TLS certificates that GnuTLS determines as invalid. | |
697 | (This option defaults to nil at present, but this is expected to change | |
698 | in a future release.) | |
699 | ||
700 | ** Hi-Lock | |
701 | ||
702 | *** New global command `M-s h .' (`highlight-symbol-at-point') highlights | |
703 | the symbol near point. | |
704 | ||
705 | *** New option `hi-lock-auto-select-face'. When non-nil, hi-lock commands | |
706 | will cycle through faces in `hi-lock-face-defaults' without prompting. | |
707 | ||
a8cb4247 | 708 | ** Icomplete |
68a8b28f | 709 | Icomplete is now more similar to Ido. |
8d3c54a0 | 710 | |
a8cb4247 GM |
711 | *** Icomplete by default now applies to all forms of minibuffer completion. |
712 | The variable `icomplete-with-completion-tables' (now a user option) | |
713 | controls this. To restore the old behavior, set it back to | |
714 | '(internal-complete-buffer). | |
8d3c54a0 | 715 | |
a8cb4247 GM |
716 | *** You can navigate through and select completions using the keys |
717 | from `icomplete-minibuffer-map'. | |
8d3c54a0 | 718 | |
a8cb4247 GM |
719 | *** The string that separates potential completions is now a customizable |
720 | option (`icomplete-separator'). The default is " | " rather than ",". | |
8d3c54a0 | 721 | |
a8cb4247 GM |
722 | *** New face `icomplete-first-match'; and new options |
723 | `icomplete-hide-common-prefix' and `icomplete-show-matches-on-no-input'. | |
724 | ||
a8cb4247 | 725 | *** The option `icomplete-show-key-bindings' has been removed. |
70c8f5ca CY |
726 | |
727 | ** Ido | |
8d3c54a0 | 728 | |
fbb764b8 | 729 | *** An Ido user manual is now included. |
8d3c54a0 | 730 | |
fbb764b8 GM |
731 | *** The option `ido-use-virtual-buffers' can now take the value `auto'. |
732 | This means to use virtual buffers if the current ido input does not match | |
733 | an existing buffer. | |
8d3c54a0 | 734 | |
fbb764b8 GM |
735 | *** The variable `ido-decorations' can optionally have two new elements, |
736 | which are the brackets to use around the sole remaining completion. | |
70c8f5ca CY |
737 | |
738 | ** Image mode | |
739 | ||
740 | *** New commands `n' (`image-next-file') and `p' (`image-previous-file') | |
741 | visit the next image file and the previous image file in the same | |
742 | directory, respectively. | |
743 | ||
744 | *** New commands to show specific frames of multi-frame images. | |
745 | `f' (`image-next-frame') and `b' (`image-previous-frame') visit the | |
746 | next or previous frame. `F' (`image-goto-frame') shows a specific frame. | |
747 | ||
748 | *** New commands to speed up, slow down, or reverse animation. | |
a7fecaa0 RS |
749 | `a +' (`image-increase-speed') and `a -' (`image-decrease-speed') to |
750 | speed up and slow down the animation. `a r' (`image-reverse-speed') | |
751 | to reverse it and `a 0' (`image-reset-speed') to reset it. | |
752 | ||
70c8f5ca CY |
753 | *** The command `image-mode-fit-frame' deletes other windows. |
754 | When toggling, it restores the frame's previous window configuration. | |
755 | It also has an optional frame argument, which can be used by Lisp | |
756 | callers to fit the image to a frame other than the selected frame. | |
757 | ||
8251c3f8 | 758 | ** New Imenu option `imenu-generic-skip-comments-and-strings'. |
70c8f5ca | 759 | |
d978812a GM |
760 | ** Info |
761 | ||
d978812a | 762 | *** New Info face `info-index-match', used to highlight matches in index |
70c8f5ca CY |
763 | entries displayed by `Info-index-next', `Info-virtual-index' and |
764 | `info-apropos'. | |
765 | ||
d978812a GM |
766 | *** The Info-edit command is obsolete. Editing Info nodes by hand |
767 | has not been relevant for some time. | |
768 | ||
70c8f5ca CY |
769 | ** JS Mode |
770 | ||
ee325f58 GM |
771 | *** New option `js-switch-indent-offset'. |
772 | ||
70c8f5ca | 773 | *** Better indentation of multiple-variable declarations. |
ee325f58 | 774 | If a declaration spans several lines, variables on the following lines |
70c8f5ca CY |
775 | are lined up to the first one. |
776 | ||
ee325f58 | 777 | *** Recognition and better indentation of continuations in array comprehensions. |
70c8f5ca | 778 | |
ee325f58 | 779 | ** MH-E has been updated to version 8.5 - see separate MH-E-NEWS file. |
70c8f5ca | 780 | |
70c8f5ca | 781 | ** Octave mode |
8251c3f8 | 782 | |
0fcfa974 | 783 | *** Font locking for Texinfo comments and new keywords. |
8251c3f8 GM |
784 | |
785 | *** Completion in Octave file buffers. | |
786 | ||
314ff318 | 787 | *** ElDoc support. |
8251c3f8 GM |
788 | |
789 | *** Jump to definition. | |
790 | ||
791 | *** Documentation lookup/search. | |
70c8f5ca | 792 | |
de6a923b | 793 | ** OPascal mode is the new name for Delphi mode |
70c8f5ca CY |
794 | |
795 | *** All delphi-* variables and functions have been renamed to opascal-*. | |
de6a923b | 796 | Obsolete aliases exist for those likely to have been used externally. |
8251c3f8 | 797 | |
de6a923b | 798 | *** The option `delphi-newline-always-indents' has been removed. |
70c8f5ca | 799 | Use `electric-indent-mode' instead. |
8251c3f8 | 800 | |
de6a923b | 801 | *** The TAB key runs the standard `indent-for-tab-command', not `delphi-tab'. |
70c8f5ca CY |
802 | |
803 | ** Package | |
804 | ||
e1b3f35f GM |
805 | *** The package library now supports digital signing of packages. |
806 | Maintainers of package archives should consider signing their packages | |
807 | to enhance security. | |
808 | ||
e1b3f35f GM |
809 | **** If the user option `package-check-signature' is non-nil, |
810 | Emacs tries to check package signatures at install time. | |
811 | The value `allow-unsigned' allows installation of unsigned packages. | |
812 | ||
e1b3f35f GM |
813 | **** The user option `package-unsigned-archives' lists archives where |
814 | Emacs will not try to check signatures. | |
815 | ||
910dc8d3 | 816 | *** New option `package-pinned-packages'. This is useful if you have multiple |
3eacddfe | 817 | archives enabled, with more than one offering a given package that you want. |
4d225fb8 | 818 | |
a215930c GM |
819 | *** In the `list-packages' buffer, you can use `f' (`package-menu-filter') |
820 | to filter the list of packages by a keyword. | |
821 | ||
1920914a | 822 | *** In the `describe-package' buffer, there are now buttons listing the |
a215930c GM |
823 | keywords related to the package. Click on a button to see other packages |
824 | related to that keyword. | |
825 | ||
70c8f5ca CY |
826 | *** The format of `archive-contents' files, generated by package |
827 | repositories, has changed to allow a new (fifth) element in the data | |
828 | vectors, containing an associative list with extra properties. | |
a215930c GM |
829 | (For example, `describe-package' uses the `:url' extra property to |
830 | display a "Homepage" header.) | |
d8a2993d | 831 | |
8251c3f8 GM |
832 | ** In Prolog mode, `prolog-use-smie' has been removed, |
833 | along with the non-SMIE indentation code. | |
1db9ceee | 834 | |
70c8f5ca | 835 | ** Remember |
f2cbfd44 | 836 | |
95160c90 GM |
837 | *** The new command `remember-notes' creates a buffer that is saved on exit. |
838 | You can use it as a more permanent *scratch* buffer. | |
20de6ab6 | 839 | |
a73fae1f GM |
840 | *** Remember can now store notes in separate files. |
841 | To use this, add `remember-store-in-files' to the `remember-handler-functions' | |
842 | option. The files are saved in `remember-data-directory' using | |
843 | names specified by `remember-directory-file-name-format'. | |
c0211c4e | 844 | |
70c8f5ca CY |
845 | ** Rmail |
846 | ||
847 | *** Customize `rmail-mbox-format' to influence some minor aspects of | |
848 | how Rmail displays non-MIME messages. | |
3a2ddc2d | 849 | |
70c8f5ca CY |
850 | *** The `unrmail' command now converts from BABYL to mboxrd format, |
851 | rather than mboxo. Customize `unrmail-mbox-format' to change this. | |
2a43515a | 852 | |
70c8f5ca | 853 | ** Ruby mode |
e38e6780 | 854 | |
de6a923b | 855 | *** Improved syntax highlighting and indentation. |
e38e6780 | 856 | |
de6a923b | 857 | *** New `electric-indent-mode' integration. |
e5e4a942 | 858 | |
de6a923b | 859 | *** New option `ruby-encoding-magic-comment-style'. |
70c8f5ca | 860 | |
de6a923b | 861 | *** New option `ruby-custom-encoding-magic-comment-template'. |
70c8f5ca CY |
862 | |
863 | *** New option `ruby-align-to-stmt-keywords'. | |
e5e4a942 | 864 | |
2f313daf DG |
865 | *** New option `ruby-align-chained-calls'. |
866 | ||
de6a923b | 867 | *** More Ruby file types have been added to `auto-mode-alist'. |
6cddebc1 | 868 | |
d289938a | 869 | ** Search and Replace |
279f9b06 | 870 | |
e5e4a942 JL |
871 | *** New global command `M-s .' (`isearch-forward-symbol-at-point') |
872 | starts a symbol (identifier) incremental search forward with the | |
873 | symbol found near point added to the search string initially. | |
874 | ||
279f9b06 JL |
875 | *** `C-x 8 RET' in Isearch mode reads a character by its Unicode name |
876 | and adds it to the search string. | |
877 | ||
4d49cc65 | 878 | *** `M-s i' in Isearch mode toggles whether search matches invisible text. |
01dea85f | 879 | |
d289938a JL |
880 | *** `query-replace' skips invisible text when `search-invisible' is nil, |
881 | and opens overlays with hidden text when `search-invisible' is `open'. | |
882 | ||
3eacddfe | 883 | *** A negative prefix argument of replacement commands replaces backward. |
3ee4cd64 JL |
884 | `M-- M-%' replaces a string backward, `M-- C-M-%' replaces a regexp |
885 | backward, `M-s w words M-- M-%' replaces a sequence of words backward. | |
886 | ||
80fa505f | 887 | *** By default, prefix arguments do not now terminate Isearch mode. |
3eacddfe | 888 | Set `isearch-allow-prefix' to nil to restore the old behavior. |
80fa505f | 889 | |
6e8cfc81 JL |
890 | *** More Isearch commands accept prefix arguments, namely |
891 | `isearch-printing-char', `isearch-quote-char', `isearch-yank-word', | |
892 | `isearch-yank-line'. | |
893 | ||
a22289f7 JL |
894 | *** Word search now matches whitespace at the beginning/end |
895 | of the search string if it contains leading/trailing whitespace. | |
896 | In an incremental word search or when using a non-nil LAX argument | |
897 | of `word-search-regexp', the lax matching can also match part of | |
898 | the first word (in addition to the lax matching of the last word). | |
3eacddfe | 899 | The same rules are now applied to the symbol search, with the difference |
a22289f7 JL |
900 | that it matches symbols, and non-symbol characters between symbols. |
901 | ||
a22359a7 | 902 | ** New SES command `ses-rename-cell' allows assignment of names to SES cells. |
6827cac1 | 903 | |
21cf4545 | 904 | ** The shell.el option `explicit-bash-args' includes --noediting by default. |
8251c3f8 | 905 | All non-ancient Bash versions support this option. |
4f0552c2 | 906 | |
70c8f5ca | 907 | ** Shell Script mode |
8b62d742 | 908 | |
a22359a7 | 909 | *** The SMIE indentation engine is now used by default - see `sh-use-smie'. |
c38a186c | 910 | |
a22359a7 | 911 | *** `sh-mode' now has its own setting for `add-log-current-defun-function'. |
b345c561 | 912 | |
d82e752c GM |
913 | ** SMIE |
914 | ||
47b73b35 | 915 | *** You can customize the SMIE indentation of a mode via `smie-config'. |
d82e752c GM |
916 | The command `smie-config-guess' can help you derive the appropriate |
917 | indentation settings, if you provide it with an indented sample file. | |
918 | Use `smie-config-save' to save the result. | |
919 | ||
47b73b35 | 920 | *** You can customize the SMIE indentation of a file by adding an entry to |
dffe37a8 | 921 | the file's local variables of the form: `eval: (smie-config-local '(RULES))'. |
47b73b35 | 922 | |
d82e752c | 923 | *** New commands `smie-config-show-indent' and `smie-config-set-indent'. |
70c8f5ca | 924 | |
363362c5 | 925 | ** SQL mode |
9b0c01f7 | 926 | |
363362c5 GM |
927 | *** Improved login monitoring and appropriate response to login failures. |
928 | New variable `sql-login-delay' defines maximum wait time for a connection. | |
929 | ||
930 | *** Oracle support. | |
9b0c01f7 | 931 | SQL*Plus script placeholders are properly highlighted and identified |
363362c5 GM |
932 | in `sql-placeholders-filter'. When starting SQL*Plus, `sql-oracle-options' |
933 | are passed before the logon parameter, as required. The default now | |
934 | includes `-L', to limit the number of logon attempts per invocation. | |
9b0c01f7 | 935 | |
8251c3f8 | 936 | ** New Term mode option `term-suppress-hard-newline'. |
ad4de702 | 937 | |
d29bf51c | 938 | ** Todo mode has been rewritten and enhanced. |
2d3c36db GM |
939 | The Todo mode user manual describes all commands and most user |
940 | options. To support some of these features, a new file format is | |
941 | used, which is incompatible with the old format; however, you can | |
942 | convert old todo and done item files to the new format on initializing | |
943 | the first new todo file, or at any later time with the provided | |
944 | conversion command. The previous version of todo-mode.el has been | |
303ea1dd GM |
945 | renamed to otodo-mode.el and is now obsolete. New features include: |
946 | ||
947 | *** Support for multiple todo files and archive files of done items. | |
948 | ||
949 | *** Renaming, reordering, moving, merging, and deleting categories. | |
950 | ||
951 | *** Sortable tabular summaries of categories and the item types they contain. | |
952 | ||
953 | *** Cross-category lists of items filtered by specific criteria. | |
954 | ||
955 | *** More fine-grained interaction with the Emacs diary, by being able to | |
956 | decide for each todo item whether it appears in the Fancy Diary display. | |
957 | ||
958 | *** Highly flexible new item insertion and item editing. | |
959 | ||
960 | *** Moving items between categories, storing done items in their category | |
961 | or in archive files, undoing or unarchiving done items. | |
962 | ||
963 | *** Reprioritizing items by inputting a numerical priority. | |
964 | ||
965 | *** Extensive customizability of operation and display, including many faces. | |
2d3c36db | 966 | |
9997d7e3 | 967 | ** Trace |
2d3c36db | 968 | |
9997d7e3 GM |
969 | *** `trace-function' and `trace-function-background' no longer prompt for |
970 | the output buffer. Unless you use a prefix argument, they output to | |
971 | `trace-buffer'. | |
2d3c36db | 972 | |
9997d7e3 GM |
973 | *** With a prefix argument, `trace-function' and `trace-function-background' |
974 | will prompt for a "context". This is a Lisp expression, whose value at the | |
975 | time the function is entered/exited is printed along with the function's | |
976 | name and arguments. | |
70c8f5ca | 977 | |
aefa2ead | 978 | ** Tramp |
26280467 | 979 | |
aefa2ead | 980 | *** New connection method "adb", which allows to access Android |
19dc8b9e MA |
981 | devices by the Android Debug Bridge. The variable `tramp-adb-program' |
982 | can be used to adapt the path of the "adb" program, if needed. | |
26280467 | 983 | |
3eacddfe GM |
984 | *** Handlers for `file-acl' and `set-file-acl' for remote machines |
985 | that support POSIX ACLs. | |
986 | ||
987 | *** Handlers for `file-notify-add-watch' and `file-notify-rm-watch' | |
988 | for remote machines that support filesystem notifications. | |
989 | ||
990 | *** The experimental url syntax for remote file names has been removed. | |
991 | ||
19dc8b9e MA |
992 | *** The connection methods "plink1", "ssh1", "ssh2", "scp1", "scp2", |
993 | "scpc" and "rsyncc" are discontinued. The ssh option | |
994 | "ControlMaster=auto" is set automatically in all ssh-based methods, | |
65bc4bb5 | 995 | when possible. See `tramp-use-ssh-controlmaster-options'. |
26280467 | 996 | |
645586dc GM |
997 | ** New URL command `url-cookie-list' displays the current cookies, |
998 | and allows you to interactively remove cookies. | |
b29daf07 | 999 | |
70c8f5ca | 1000 | ** VC and related modes |
bb102690 | 1001 | |
70c8f5ca CY |

1003 | whole tree revisions. | |
fa5265fc | 1004 | |
70c8f5ca CY |
1005 | *** In VC directory mode, `L' lists the change log for the current VC |
1006 | controlled tree in a window. | |
fa5265fc | 1007 | |
70c8f5ca CY |
1008 | *** In VC directory mode, `I' shows a log of changes that will be |
1009 | received with a pull operation. | |
fa5265fc | 1010 | |
70c8f5ca CY |
1011 | *** `C-x v G' (globally) and `G' (in VC directory mode) ignores a file |
1012 | under current version control system. When called with a prefix | |
1013 | argument, you can remove a file from the ignored file list. | |
fa5265fc | 1014 | |
70c8f5ca | 1015 | ** VHDL mode |
fa5265fc | 1016 | |

fa5265fc | 1020 | |
8251c3f8 | 1021 | ** The Woman commands `woman-default-faces' and `woman-monochrome-faces' |
70c8f5ca | 1022 | are obsolete. Customize the `woman-*' faces instead. |
fa5265fc | 1023 | |

02f473a4 | 1065 | |
70c8f5ca | 1066 | ** New package `eww' is a built-in web browser. |
3eacddfe | 1067 | (It is only available if Emacs is compiled with libxml2 support.) |
002668e1 | 1068 | |
70c8f5ca | 1069 | ** New package nadvice.el offers lighter-weight advice facilities. |
231d8498 | 1070 | It is layered as: |
2d3c36db | 1071 | |
3eacddfe GM |
1072 | *** `add-function'/`remove-function', which can be used to add/remove code on |
1073 | any function-carrying place, such as process filters or `<foo>-function' hooks. | |
2d3c36db | 1074 | |
3eacddfe | 1075 | *** `advice-add'/`advice-remove' to add/remove a piece of advice on a named |
7c324762 | 1076 | function, much like `defadvice' does. |
231d8498 | 1077 | |
70c8f5ca | 1078 | ** New package frameset.el. |
8cd4636c JB |
1079 | It provides a set of operations to save a frameset (the state of all |
1080 | or a subset of the existing frames and windows, somewhat similar to a | |
1081 | frame configuration), both in-session and persistently, and restore it | |
1082 | at some point in the future. | |
1083 | ||
70c8f5ca CY |
1084 | ** New package filenotify.el provides an interface for file system |
1085 | notifications. It requires that Emacs be compiled with one of the | |
f1c7dee9 MA |

1087 | ||
3eacddfe GM |
1088 | ** New minor modes `prettify-symbols-mode' and `global-prettify-symbols-mode' |
1089 | display specified symbols as composed characters. E.g., in Emacs Lisp mode, | |
1090 | this replaces the string "lambda" with the Greek lambda character. | |
a104f656 | 1091 | |
3eacddfe GM |
1092 | ** New minor mode `superword-mode'. |
1093 | This overrides the default word motion commands to treat "symbol_words" | |
1094 | as a single word, similar to what `subword-mode' does. | |

1097 | * Incompatible Lisp Changes in Emacs 24.4 | |
70c8f5ca | 1098 | |
0b31660d | 1099 | ** The default file coding for Emacs Lisp files is now utf-8. |
70c8f5ca CY |
1100 | (See `file-coding-system-alist'.) In most cases, this change is |
1101 | transparent, but files that contain unusual characters without | |
1102 | specifying an explicit coding system may fail to load with obscure | |
1103 | errors. You should either convert them to utf-8 or add an explicit | |
1104 | `coding:' cookie. | |
0b31660d | 1105 | |
3eacddfe GM |
1106 | ** Default process filters and sentinels are not nil any more. |
1107 | Instead they default to a function that does what the nil value used to do. | |
1108 | ||
1109 | ** Overlay priority does not have to be nil or a non-negative integer. | |
1110 | Overlay priority can be other kinds of Lisp objects. We didn't yet | |
1111 | decide whether other types of values are stable enough, and therefore | |
1112 | don't feel it's right to document them. For now, don't assume in your | |
1113 | code that the values of overlay priority can only be either nil or an | |
1114 | integer, always test them with an appropriate predicate to be one or | |
1115 | the other. If you need to sort arbitrary overlays into priority | |
1116 | order, `overlays-at' can now optionally do this. | |
1117 | You should still only specify integer priorities on overlays you create. | |
1118 | ||
1119 | ** The cars of the elements in `interpreter-mode-alist' are now | |
1120 | treated as regexps rather than literal strings. | |
1121 | ||
70c8f5ca | 1122 | ** `overriding-terminal-local-map' no longer replaces the local keymaps. |
bfa3acd6 SM |
1123 | It used to disable the minor mode, major mode, and text-property keymaps, |
1124 | whereas now it simply has higher precedence. | |
1125 | ||
3eacddfe GM |
1126 | ** `kill-region' has lost its `yank-handler' optional argument. |
1127 | ||
1128 | ** `(input-pending-p)' no longer runs other timers that are ready to run. | |
1129 | The new optional CHECK-TIMERS parameter allows for the prior behavior. | |
1130 | ||
1131 | ** `defvar' and `defcustom' in a let-binding affect the "external" default. | |
1132 | ||
1133 | ** The syntax of ?» and ?« is now punctuation instead of matched parens. | |
1134 | Some languages match those as »...«, and others as «...», so it is | |
1135 | better for Emacs to stay neutral by default. | |
1aa8d505 | 1136 | |
25c09217 | 1137 | ** `read-event' does not return decoded chars in ttys any more. |
0f1d2934 CY |
1138 | As was the case in Emacs 22 and before, the decoding of terminal |
1139 | input, according to `keyboard-coding-system', is not performed in | |
1140 | `read-event' any more. But unlike in Emacs 22, this decoding is still | |
3eacddfe | 1141 | done before `input-decode-map', `function-key-map', etc. |
99d0d6dc | 1142 | |
3eacddfe | 1143 | ** In `symbol-function', nil and "unbound" are indistinguishable. |
0f1d2934 CY |
1144 | `symbol-function' does not signal a `void-function' error any more. |
1145 | To determine if a symbol's function definition is void, use `fboundp'. | |
eadf1faa | 1146 | |
3c442f8b SM |
1147 | ** `defadvice' does not honor the `freeze' flag and cannot advise |
1148 | special-forms any more. | |
7db1bda8 | 1149 | |
2200a8c9 CY |
1150 | ** `dolist' no longer binds VAR while evaluating the RESULT form, |
1151 | when lexical binding is enabled. Previously, VAR was bound to nil, | |
1152 | which often led to spurious unused-variable warnings. | |
da03ef8a | 1153 | |
7c3d167f RF |
1154 | ** The return value of `backup-buffer' has changed. |
1155 | The second argument is no longer an SELinux context, instead it is an | |
1156 | alist of extended attributes as returned by the new function | |
1157 | `file-extended-attributes'. The attributes can be applied to another | |
1158 | file using `set-file-extended-attributes'. | |
1159 | ||
a560b856 PE |
1160 | ** By default `copy-file' no longer copies file permission bits to an |
1161 | existing destination; and it sets the file permission bits of a newly | |
1162 | created destination to those of the source, masked by the default file | |
1163 | permissions. To copy the file permission bits, pass t as the | |
1164 | PRESERVE-PERMISSIONS argument of `copy-file'. | |
1165 | ||
954b166e PE |
1166 | ** `visited-file-modtime' now returns -1 for nonexistent files. |
1167 | Formerly it returned a list (-1 LOW USEC PSEC), but this was ambiguous | |
1168 | in the presence of files with negative time stamps. | |
1af4c220 | 1169 | |
3eacddfe GM |
1170 | ** Frame-local variables that affect redisplay do not work any more. |
1171 | More specifically, redisplay does not bother to check for a frame-local | |
1172 | value when looking up variables. | |
1af4c220 | 1173 | |
3eacddfe GM |
1174 | ** In compiled Lisp files, the header no longer includes a timestamp. |
1175 | ||
1176 | ** The option `inhibit-local-menu-bar-menus' has been removed. | |
819ed0f5 | 1177 | |
c57b2d76 | 1178 | \f |
97a1cd9d | 1179 | * Lisp Changes in Emacs 24.4 |
57618ecf | 1180 | |
3eacddfe GM |
1181 | ** Change to the Emacs Lisp coding conventions: the package descriptor |
1182 | and name of global variables, constants, and functions should be separated | |
1183 | by two hyphens if the symbol is not meant to be used by other packages. | |
642d7ae8 | 1184 | |
3eacddfe | 1185 | ** The second argument of `eval' can now specify a lexical environment. |
70c8f5ca CY |
1186 | |
1187 | ** New macro `define-alternatives' can be used to define generic commands. | |
1188 | Generic commands are interactive functions whose implementation can be | |
1189 | selected among several alternatives, as a matter of user preference. | |
1190 | ||
3eacddfe GM |
1191 | ** Numeric comparison functions =, <, >, <=, >= can now take many arguments. |
1192 | ||
1193 | ** New functions `special-form-p' and `macrop'. | |
1194 | ||
1195 | ** New macro `with-eval-after-load'. | |
1196 | This is like the old `eval-after-load', but better behaved. | |
1197 | ||
189e7007 GM |
1198 | ** If you give a symbol a `defalias-fset-function' property, `defalias' |
1199 | on that symbol will use the associated value as a function to call | |
1200 | in place of `fset'. | |
642d7ae8 | 1201 | |
642d7ae8 CY |
1202 | ** New variable `enable-dir-local-variables'. |
1203 | Directory-local variables are ignored if this is nil. This may be | |
1204 | useful for modes that want to ignore directory-locals while still | |
1205 | respecting file-local variables. | |
70c8f5ca | 1206 | |
b8630261 GM |
1207 | ** `read-regexp' now uses the new variable `read-regexp-defaults-function' |
1208 | as a function to call to provide default values. | |
1209 | ||
3eacddfe | 1210 | ** New functions `group-gid' and `group-real-gid'. |
70c8f5ca | 1211 | |
3eacddfe GM |
1212 | ** New function `get-pos-property'. |
1213 | ||
1214 | ** New hook `pre-redisplay-function'. | |
1215 | ||
1216 | ** `byte-compile-interactive-only-functions' is now obsolete. | |
1217 | To specify that a command should only be called interactively, give it | |
1218 | a non-nil `interactive-only' property. | |
1219 | ||
1220 | ** New function `string-suffix-p'. | |
1221 | ||
1222 | ** `split-string' now takes an optional argument TRIM. | |
1223 | The value, if non-nil, is a regexp that specifies what to trim from | |
1224 | the start and end of each substring. | |
1225 | ||
1226 | ** Completion | |
70c8f5ca | 1227 | |
d9263618 GM |
1228 | *** The separator used by `completing-read-multiple' is now a regexp. |
1229 | The default `crm-separator' has been changed to allow surrounding spaces | |
642d7ae8 | 1230 | around the comma. |
70c8f5ca | 1231 | |
f8b18150 GM |
1232 | *** New function `completion-table-with-cache' is a wrapper for |
1233 | `completion-table-dynamic' that caches the result of the last lookup. | |
1234 | ||
1235 | *** New function `completion-table-merge' to combine several | |
1236 | completion tables by merging their completions. | |
1237 | ||
3eacddfe GM |
1238 | *** The `common-substring' argument of `display-completion-list', |
1239 | which has been documented as obsolete since Emacs 23.1, is now _really_ | |
1240 | obsolete, and no longer advertised. Instead either call | |
1241 | `completion-hilit-commonality' to add the highlighting; or use | |
1242 | `completion-all-completions', which returns highlighted strings. | |
98bd6b32 | 1243 | |
3eacddfe | 1244 | ** Encoding and decoding of text |
642d7ae8 | 1245 | |
3eacddfe GM |
1246 | *** New coding-system `prefer-utf-8'. |
1247 | This is like `undecided' but prefers UTF-8 on decoding if the text to | |
1248 | be decoded does not contain any invalid UTF-8 sequences. On encoding, | |
1249 | any non-ASCII characters are automatically encoded as UTF-8. | |
642d7ae8 | 1250 | |
3eacddfe GM |
1251 | *** New attributes of coding-systems whose type is `undecided'. |
1252 | Two new attributes, `:inhibit-null-byte-detection' and | |
1253 | `:inhibit-iso-escape-detection', determine how to detect encoding of | |
1254 | text that includes null bytes and ISO-2022 escape sequences, respectively. | |
1255 | Each of these attributes can be either nil, zero, or t. If t, decoding | |
1256 | text ignores null bytes and ISO-2022 sequences, respectively. If nil, | |
1257 | null bytes cause text to be decoded with no-conversion, and ISO-2022 | |
1258 | sequences cause Emacs to assume the text is encoded in one of the ISO-2022 | |
1259 | encodings, such as iso-2022-7bit. If zero, Emacs consults the variables | |
1260 | `inhibit-null-byte-detection' and `inhibit-iso-escape-detection'. | |
1261 | The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer | |
1262 | UTF-8 encoding and decoding, whenever possible. | |
3e0b94e7 | 1263 | |
3eacddfe GM |
1264 | These attributes are only meaningful for coding-systems of type `undecided'. |
1265 | (The type of a coding-system is determined by its `:coding-type' attribute | |
1266 | and can be accessed by calling the `coding-system-type' function.) | |
ebb99847 | 1267 | |
3eacddfe | 1268 | ** Error-handling |
8c27f5ff | 1269 | |
642d7ae8 | 1270 | *** New function `define-error'. |
54bd972f | 1271 | |
642d7ae8 | 1272 | *** `with-demoted-errors' takes an additional argument `format'. |
7fd72e2c | 1273 | |
3eacddfe | 1274 | ** Faces |
de0503df | 1275 | |
3eacddfe GM |
1276 | *** Face specs set via Custom themes now replace the `defface' spec |
1277 | rather than inheriting from it. In other words, setting a face via a | |
1278 | theme now behaves like setting it via Customize: you only need to | |
1279 | specify the attributes that you want, you don't need to unset those | |
1280 | that you don't want. | |
d3e9f3a8 | 1281 | |
3eacddfe GM |
1282 | *** The function `face-spec-set' is now like `setq' for face specs. |
1283 | Its third arg now accepts values specifying a face spec type (defface, | |
1284 | custom, or override spec), and the relevant spec is set accordingly. | |
d36ed1c8 | 1285 | |
3eacddfe GM |
1286 | *** New face spec attribute :distant-foreground |
1287 | specifies foreground to use if background color is near the foreground | |
1288 | color that would otherwise have been used. | |
2bb3a748 | 1289 | |
3eacddfe GM |
1290 | *** New function `add-face-text-property', which can be used to |
1291 | conveniently prepend/append new face properties. | |
d36ed1c8 | 1292 | |
3eacddfe GM |
1293 | *** New face characteristic (supports :underline (:style wave)) |
1294 | specifies whether or not the terminal can display a wavy line. | |
41ce6f70 | 1295 | |
3eacddfe | 1296 | ** File-handling |
70c8f5ca CY |
1297 | |
1298 | *** Support for filesystem notifications. | |
81606b10 RS |
1299 | Emacs now supports notifications of filesystem changes, such as |
1300 | creation, modification, and deletion of files. This requires the | |
2f23b3ab | 1301 | `glib' API, or the 'inotify' API (on GNU/Linux systems only). On |
3eacddfe | 1302 | MS-Windows systems, this is supported for Windows XP and newer. |
81606b10 | 1303 | |
70c8f5ca CY |
1304 | *** The 9th element returned by `file-attributes' is now unspecified. |
1305 | Formerly, it was t if the file's gid would change if file were deleted | |
1306 | and recreated. This value has been inaccurate for years on many | |
1307 | platforms, and nobody seems to have noticed or cared. | |
1308 | ||
1309 | *** The 6th argument to `copy-file' has been renamed to | |
a560b856 PE |
1310 | PRESERVE-PERMISSIONS as it now handles ACL entries and the traditional |
1311 | Unix file permission bits as well as SELinux context. | |
70c8f5ca CY |
1312 | |
1313 | *** The function `file-ownership-preserved-p' now has an optional | |
1314 | argument GROUP which causes it check for file group too. This can be | |
1315 | used in place of the 9th element of `file-attributes'. | |
1316 | ||
3eacddfe GM |
1317 | *** The function `set-visited-file-modtime' now accepts a 0 or -1 argument, |
1318 | with the same interpretation as the returned value of `visited-file-modtime'. | |
3c334c14 | 1319 | |
f0c954fa GM |
1320 | ** Image API |
1321 | ||
f0c954fa GM |
1322 | *** `image-animated-p' is now `image-multi-frame-p'. |
1323 | It returns non-nil for any image that contains multiple frames, | |
1324 | whether or not it specifies a frame delay. | |
1325 | ||
642d7ae8 CY |
1326 | *** New variable `image-default-frame-delay' gives the frame delay for |
1327 | animated images which do not specify a frame delay. | |
f0c954fa | 1328 | |
f0c954fa GM |
1329 | *** New functions `image-current-frame' and `image-show-frame' for getting |
1330 | and setting the current frame of a multi-frame image. | |
1331 | ||
3eacddfe | 1332 | ** Revert and Autorevert |
fa5265fc | 1333 | |
3eacddfe GM |
1334 | *** If Emacs is compiled with file notification support, it uses notifications |
1335 | instead of checking file time stamps. To disable this, set the user option | |
1336 | `auto-revert-use-notify' to nil. Alternatively, you can specify a regular | |
1337 | expression matching directories to be excluded from file notifications via | |
1338 | `auto-revert-notify-exclude-dir-regexp'. | |
1b796d6b | 1339 | |
3eacddfe GM |
1340 | *** The default values of `buffer-stale-function', `revert-buffer-function', |
1341 | and `revert-buffer-insert-file-contents-function' are no longer nil. | |
1342 | Instead they default to functions that do what the nil value used to. | |
1b796d6b | 1343 | |
3eacddfe | 1344 | *** `buffer-stale-function' is now used for buffers visiting files too. |
1b796d6b | 1345 | |
3eacddfe GM |
1346 | *** The new user option `auto-revert-remote-files' enables reversion |
1347 | of remote files, if non-nil. | |
1b796d6b | 1348 | |
3eacddfe | 1349 | ** Terminal |
70c8f5ca | 1350 | |
3eacddfe GM |
1351 | *** Functions to pop up menus and dialogs now work on all terminals, |
1352 | including TTYs. This includes `x-popup-menu', `x-popup-dialog', | |
1353 | `message-box', `yes-or-no-p', etc. | |
97976f9f | 1354 | |
3eacddfe GM |
1355 | The function `display-popup-menus-p' will now return non-nil for a |
1356 | display or frame whenever a mouse is supported on that display or frame. | |
1357 | ||
1358 | *** New hook `tty-setup-hook', run at the end of initializing a text terminal. | |
1359 | ||
1360 | *** The hook `term-setup-hook' is obsolete. It is entirely equivalent | |
1361 | to `emacs-startup-hook'. See also the new `tty-setup-hook'. | |
73dbf960 | 1362 | |
ca5fd02c GM |
1363 | ** Minor internal changes to the details of lock files. |
1364 | The lock for DIR/FILE is now _always_ DIR/.#FILE. | |
1365 | If DIR/.#FILE already exists and is not an Emacs lock file, | |
1366 | Emacs makes no attempt to lock DIR/FILE. (Previously, it fell back to | |
1367 | numbered lock files DIR/.#FILE.0...). | |
1368 | On file systems that do not support symbolic links, the lock is now a | |
1369 | regular file with contents being what would have been in the symlink. | |
1370 | ||
3eacddfe GM |
1371 | ** New bool-vector set operation functions: |

8fa2654e | 1380 | |
3eacddfe GM |
1381 | ** New library subr-x.el with miscellaneous small utility functions: |
1382 | *** `hash-table-keys' | |
1383 | *** `hash-table-values' | |
1384 | *** `string-blank-p' | |
1385 | *** `string-empty-p' | |
1386 | *** `string-join' | |
1387 | *** `string-reverse' | |

1390 | *** `string-trim' | |
1391 | *** `string-remove-prefix' | |
1392 | *** `string-remove-suffix' | |
1393 | ||
1394 | ** The `time-to-seconds' alias to `float-time' is no longer marked obsolete. | |
1395 | ||
1396 | ** The spelling of the rx.el category `chinese-two-byte' has been | |
1397 | corrected (the first 'e' was missing). | |
1398 | ||
1399 | ** EIEIO namespace cleanup, obsolete-aliasing functions to use `eieio-' prefix: | |
1400 | *** object-name -> eieio-object-name | |

1443 | ** Improved fullscreen support on Mac OS X 10.7 and newer, where the | |
1444 | default fullscreen method is now "native" fullscreen. To use the | |
1445 | old style fullscreen, customize `ns-use-native-fullscreen' to nil. | |
1446 | ||
1447 | ** On Mac OS X 10.7 and newer, Emacs can use sRGB colorspace, and does so | |
1448 | by default. Customize `ns-use-srgb-colorspace' to go back to the old method. | |
1449 | Note that this does not apply to images. | |
1450 | ||
7605d081 GM |
1451 | ** The procedure for building Emacs on MS-Windows has changed. |
1452 | It is now built by running the same configure script as on all other | |
1453 | platforms. This requires the MSYS environment and MinGW development | |
1454 | tools. See the updated instructions in nt/INSTALL for details. | |
671d4bfc | 1455 | |
3eacddfe | 1456 | Using the Posix configure script and Makefiles also means a change in |
671d4bfc GM |
1457 | the directory structure of the Emacs installation on Windows. It is |
1458 | now the same as on GNU and Unix systems. In particular, the auxiliary | |
1459 | programs, such as cmdproxy.exe and hexl.exe, are in | |
1460 | libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs | |
1461 | version), version-independent site-lisp is in share/emacs/site-lisp, | |
1462 | version-specific Lisp files are in share/emacs/VERSION/lisp and in | |
1463 | share/emacs/VERSION/site-lisp, Info docs are in share/info, and data | |
1464 | files are in share/emacs/VERSION/etc. (Emacs knows about all these | |
1465 | directories and will find the files in there automatically; there's no | |
1466 | need to set any variables due to this change.) | |
1467 | ||
7df14908 EZ |
1468 | ** Emacs on Windows 2000 and later can now access files and directories |
1469 | whose names cannot be encoded in the current system codepage. | |
1470 | ||
1471 | The new variable `w32-unicode-filenames' controls this feature: if it | |
1472 | is t, Emacs uses Unicode APIs to pass file names to system calls, | |
1473 | which lifts the limitation of file names to the current locale. | |
1474 | ||
3eacddfe GM |
1475 | ** Lock files now work on MS-Windows. |
1476 | This helps to prevent losing your edits if the same file is being | |
1477 | edited in another Emacs session or by another user. See the node | |
1478 | "Interlocking" in the Emacs User Manual for the details. To disable | |
1479 | file locking, customize `create-lockfiles' to nil. | |
1480 | ||
5248293f GM |
1481 | ** The "generate a backtrace on fatal error" feature now works on MS Windows. |
1482 | The backtrace is written to the 'emacs_backtrace.txt' file in the | |
1483 | directory where Emacs was running. | |
1484 | ||
8549f9e8 EZ |
1485 | ** The variable `buffer-file-type' is no longer supported. |
1486 | Setting it has no effect, and %t in the mode-line format is ignored. | |
1487 | Likewise, `file-name-buffer-file-type-alist' is now obsolete, and | |
1488 | modifying it has no effect. | |

b8df54ff | 1492 | |
6bc66c10 | 1493 | ** The default X toolkit is now Gtk+ version 3. |
823b2fb6 GM |
1494 | If you don't pass `--with-x-toolkit' to configure, or if you use |
1495 | `--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try | |
1496 | to build with Gtk+ version 3, and if that fails, try Gtk+ version 2. | |
d71a6517 | 1497 | You can explicitly require a specific version by passing |
823b2fb6 | 1498 | `--with-x-toolkit=gtk2' or `--with-x-toolkit=gtk3' to configure. |
da3d2105 | 1499 | |
6bc66c10 | 1500 | ** New configure option `--enable-link-time-optimization', to utilize |
da3d2105 DA |
1501 | an appropriate feature provided by GCC since version 4.5.0. |
1502 | ||
33cb2043 GM |
1503 | ** New configure option `--without-all' to disable most of the optional |
1504 | features (image support, etc.) that are normally enabled by default. | |
b8df54ff | 1505 | |
33cb2043 GM |
1506 | ** New configure option `--enable-gcc-warnings' (for developing/debugging |
1507 | Emacs). If building with GCC, this enables compile-time checks that | |
64420fcd GM |
1508 | warn/give errors about possibly-questionable C code. On a recent GNU |
1509 | system there should be no warnings; on older and on non-GNU systems | |
1510 | the results may be useful to developers. | |
b8df54ff | 1511 | |
823b2fb6 | 1512 | ** The configure option `--enable-use-lisp-union-type' has been |
6bc66c10 | 1513 | renamed to `--enable-check-lisp-object-type', as the resulting |
d71a6517 GM |
1514 | Lisp_Object type no longer uses a union to implement the compile time |
1515 | check that this option enables. | |
1516 | ||
823b2fb6 | 1517 | ** The configure option `--disable-maintainer-mode' has been removed, |
501390c5 PE |
1518 | as it was confusingly-named and rarely useful. |
1519 | ||
f14a4380 GM |
1520 | ** The configure options `--program-prefix', `--program-suffix', and |
1521 | `--program-transform-name' apply to more than just the installed | |
1522 | binaries. Now they also affect the man pages, icons, and the | |
1523 | etc/emacs.desktop file; but not the info pages, since this would break | |
1524 | links between the various manuals. | |
1a9c6830 | 1525 | |
823b2fb6 GM |
1526 | ** You can use `NO_BIN_LINK=t make install' to prevent the installation |
1527 | overwriting "emacs" in the installation bin/ directory with a link | |
6bc66c10 | 1528 | to "emacs-VERSION". |
823b2fb6 | 1529 | |
a4a18b8b GM |
1530 | ** Emacs uses libtinfo in preference to libncurses, if available. |
1531 | ||
187e9b90 GM |
1532 | ** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and |
1533 | /usr/pkg/lib to the linker search path. You must add them yourself if | |
1534 | you want them. | |
1535 | ||
6bc66c10 | 1536 | ** The standalone scripts `rcs-checkin' and `vcdiff' have been removed |
276d5f5d GM |
1537 | (from the bin and libexec directories, respectively). The former is |
1538 | no longer relevant, the latter is replaced by lisp (in vc-sccs.el). | |

2a1e2476 | 1541 | * Startup Changes in Emacs 24.3 |
e5fcdb5e GM |
1542 | |
1543 | ** Emacs no longer searches for `leim-list.el' files beneath the standard | |
1544 | lisp/ directory. There should not be any there anyway. If you have | |
823b2fb6 | 1545 | been adding them there, put them somewhere else; e.g., site-lisp. |
e5fcdb5e | 1546 | |
4107c81e GM |
1547 | ** The `--no-site-lisp' command line option now works for Nextstep builds. |

6bc66c10 | 1552 | ** Help |
c89926a5 | 1553 | |
6bc66c10 | 1554 | *** `C-h f' (`describe-function') can now perform autoloading. |
c89926a5 CY |
1555 | When this command is called for an autoloaded function whose docstring |
1556 | contains a key substitution construct, that function's library is | |
1557 | automatically loaded, so that the documentation can be shown | |
1558 | correctly. To disable this, set `help-enable-auto-load' to nil. | |
1559 | ||
1560 | *** `C-h f' now reports previously-autoloaded functions as "autoloaded", | |
1561 | even after their associated libraries have been loaded (and the | |
1562 | autoloads have been redefined as functions). | |
1563 | ||
6bc66c10 | 1564 | ** ImageMagick |
cd996018 | 1565 | |
6bc66c10 GM |
1566 | *** Images displayed via ImageMagick now support transparency and the |
1567 | :background image specification property. | |
cd996018 | 1568 | |
6bc66c10 | 1569 | *** When available, ImageMagick support is automatically enabled. |
c505aaeb CY |
1570 | It is no longer necessary to call `imagemagick-register-types' |
1571 | explicitly to install ImageMagick image types; that function is called | |
7d806bfe | 1572 | automatically at startup, or when customizing an imagemagick- option. |
2f940384 | 1573 | |
c505aaeb | 1574 | *** Setting `imagemagick-types-inhibit' to t now disables the use of |
823b2fb6 GM |
1575 | ImageMagick to view images. (You must call `imagemagick-register-types' |
1576 | afterwards if you do not use customize to change this.) | |
2f940384 | 1577 | |
7afbaca4 | 1578 | *** The new variable `imagemagick-enabled-types' also affects which |
60b5f187 GM |
1579 | ImageMagick types are treated as images. The function |
1580 | `imagemagick-filter-types' returns the list of types that will be | |
1581 | treated as images. | |
c505aaeb | 1582 | |
6bc66c10 GM |
1583 | ** Minibuffer |
1584 | ||
1585 | *** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the | |
1586 | next and previous path separator, respectively. | |
c505aaeb | 1587 | |
6bc66c10 GM |
1588 | *** `minibuffer-electric-default-mode' can shorten "(default ...)" to "[...]" |
1589 | in minibuffer prompts. Just set `minibuffer-eldef-shorten-default' | |
1590 | non-nil before enabling the mode. | |
1591 | ||
1592 | ** Mode line | |
1593 | ||
1594 | *** New option `mode-line-default-help-echo' specifies the help text | |
1595 | (shown in a tooltip or in the echo area) for any part of the mode line | |
1596 | that does not have its own specialized help text. | |
1597 | ||
1598 | *** You can now click mouse-3 in the coding system indicator to invoke | |
1599 | `set-buffer-file-coding-system'. | |
1600 | ||
1601 | ** Server and client | |
2f940384 | 1602 | |
f938eda9 CY |
1603 | *** emacsclient now obeys string values for `initial-buffer-choice', |
1604 | if it is told to open a new frame without specifying any file to visit | |
1605 | or expression to evaluate. | |
db80bdc8 | 1606 | |
f938eda9 | 1607 | *** New option `server-auth-key' specifies a shared server key. |
f938eda9 CY |
1608 | |
1609 | ** Emacs now generates backtraces on fatal errors. | |
1610 | On encountering a fatal error, Emacs now outputs a textual description | |
1611 | of the fatal signal, and a short backtrace on platforms like glibc | |
5248293f | 1612 | that support backtraces. |
2e2d2a13 | 1613 | |
6bc66c10 GM |
1614 | ** `C-x C-q' is now bound to the new minor mode `read-only-mode'. |
1615 | This minor mode replaces `toggle-read-only', which is now obsolete. | |
1616 | ||
1617 | ** Most `y-or-n' prompts now allow you to scroll the selected window. | |
1618 | Typing `C-v' or `M-v' at a y-or-n prompt scrolls forward or backward | |
1619 | respectively, without exiting from the prompt. | |
1620 | ||
1621 | ** In the Package Menu, newly-available packages are listed as "new", | |
1622 | and sorted above the other "available" packages by default. | |
1623 | ||
9475054f | 1624 | ** If your Emacs was built from a repository checkout, the new variable |
0bfbd67c | 1625 | `emacs-bzr-version' contains information about the bzr revision used. |
de6ff46d | 1626 | |
6bc66c10 | 1627 | ** New option `create-lockfiles' specifies usage of lockfiles. |
f938eda9 CY |
1628 | It defaults to t. Changing it to nil inhibits the creation of lock |
1629 | files (use this with caution). | |
dc0f75c8 | 1630 | |
6bc66c10 GM |
1631 | ** New option `enable-remote-dir-locals', if non-nil, allows directory-local |
1632 | variables on remote hosts. | |
21ffb35a | 1633 | |
f85f636a CY |
1634 | ** The entry for PCL-CVS has been removed from the Tools menu. |
1635 | The PCL-CVS commands are still available via the keyboard. | |
1636 | ||
6bc66c10 GM |
1637 | ** Using "unibyte: t" in Lisp source files is obsolete. |
1638 | Use "coding: raw-text" instead. | |
1639 | ||
e78e7e48 CY |
1640 | ** In the buffer made by `M-x report-emacs-bug', the `C-c m' binding |
1641 | has been changed to `C-c M-i' (`report-emacs-bug-insert-to-mailer'). | |
1642 | The previous binding, introduced in Emacs 24.1, was a mistake, because | |
1643 | `C-c LETTER' bindings are reserved for user customizations. | |
1644 | ||
6bc66c10 | 1645 | ** Internationalization |
2f940384 | 1646 | |
f938eda9 | 1647 | *** New language environment: Persian. |
2f940384 | 1648 | |
f938eda9 CY |
1649 | *** New input method `vietnamese-vni'. |
1650 | ||
6bc66c10 | 1651 | ** Nextstep (GNUstep / Mac OS X) port |
2f940384 | 1652 | |
823b2fb6 | 1653 | *** Support for fullscreen and the frame parameter fullscreen. |
2f940384 | 1654 | |
1a9c6830 GM |
1655 | *** A file dialog is used for open/save operations initiated from the |
1656 | menu/toolbar. | |

6bc66c10 | 1661 | ** Search and Replace |
d39d3c8e | 1662 | |
f938eda9 CY |
1663 | *** Non-regexp Isearch now performs "lax" space matching. |
1664 | Each sequence of spaces in the supplied search string may match any | |
1665 | sequence of one or more whitespace characters, as specified by the | |
1666 | variable `search-whitespace-regexp'. (This variable is also used by a | |
823b2fb6 | 1667 | similar existing feature for regexp Isearch.) |
2f940384 | 1668 | |
f938eda9 CY |
1669 | *** New Isearch command `M-s SPC' toggles lax space matching. |
1670 | This applies to both ordinary and regexp Isearch. | |
2f940384 | 1671 | |
f938eda9 CY |
1672 | *** New option `replace-lax-whitespace'. |
1673 | If non-nil, `query-replace' uses flexible whitespace matching too. | |
1674 | The default is nil. | |
2f940384 | 1675 | |
b9cb2387 JL |
1676 | *** Global `M-s _' starts a symbol (identifier) incremental search, |
1677 | and `M-s _' in Isearch toggles symbol search mode. | |
1678 | `M-s c' in Isearch toggles search case-sensitivity. | |
1679 | ||
6bc66c10 | 1680 | ** Navigation commands |
48de8b12 | 1681 | |
6bc66c10 GM |
1682 | *** New binding `M-g c' for `goto-char'. |
1683 | ||
1684 | *** New binding `M-g TAB' for `move-to-column'. | |
1685 | ||
1686 | *** `M-g TAB' (`move-to-column') prompts for a column number if called | |
1687 | interactively with no prefix arg. Previously, it moved to column 1. | |
1688 | ||
1689 | ** New option `yank-handled-properties' allows processing of text | |
1690 | properties on yanked text, in ways that are more general than just | |
1691 | removing them (as is done by `yank-excluded-properties'). | |
48de8b12 | 1692 | |
48de8b12 CY |
1693 | ** New option `delete-trailing-lines' specifies whether |
1694 | M-x delete-trailing-whitespace should delete trailing lines at the end | |
1695 | of the buffer. It defaults to t. | |
1696 | ||
f938eda9 | 1697 | ** `C-u M-=' now counts lines/words/characters in the entire buffer. |
826b3235 | 1698 | |
48de8b12 CY |
1699 | ** `C-x 8 RET' is now bound to `insert-char', which is now a command. |
1700 | `ucs-insert' is now an obsolete alias for `insert-char'. | |
b2459884 | 1701 | |
48de8b12 CY |
1702 | ** The `z' key no longer has a binding in most special modes. |
1703 | It used to be bound to `kill-this-buffer', but `z' is too easy to | |
1704 | accidentally type. | |
f938eda9 | 1705 | |
6bc66c10 GM |
1706 | ** New command `C-x r M-w' (`copy-rectangle-as-kill'). |
1707 | It copies the region-rectangle as the last rectangle kill. | |
f938eda9 | 1708 | |
6bc66c10 | 1709 | ** Registers |
f938eda9 | 1710 | |
823b2fb6 | 1711 | *** `C-x r +' is now overloaded to invoke `append-to-register'. |
f938eda9 | 1712 | |
f938eda9 | 1713 | *** New option `register-separator' specifies the register containing |
823b2fb6 GM |
1714 | the text to put between collected texts for use with |
1715 | M-x append-to-register and M-x prepend-to-register. | |

ae4969c2 | 1719 | |
6bc66c10 | 1720 | ** Common Lisp emulation (CL) |
f938eda9 | 1721 | |
89660017 | 1722 | *** CL's main entry is now (require 'cl-lib). |
823b2fb6 GM |
1723 | `cl-lib' is like the old `cl' except that it uses the namespace cleanly; |
1724 | i.e., all its definitions have the "cl-" prefix (and internal definitions | |
1725 | use the "cl--" prefix). | |
7c1898a7 | 1726 | |
823b2fb6 GM |
1727 | If `cl' provided a feature under the name `foo', then `cl-lib' |
1728 | provides it under the name `cl-foo' instead; with the exceptions of the | |
1729 | few `cl' definitions that had to use `foo*' to avoid conflicts with | |
1730 | pre-existing Elisp entities. These have been renamed to `cl-foo' | |
1731 | rather than `cl-foo*'. | |
7c1898a7 | 1732 | |
92246540 | 1733 | The old `cl' is now deprecated and is mainly just a bunch of aliases that |
823b2fb6 | 1734 | provide the old, non-prefixed names. Some exceptions are listed below: |
7c1898a7 | 1735 | |
89660017 SM |
1736 | *** `cl-flet' is not like `flet' (which is deprecated). |
1737 | Instead it obeys the behavior of Common-Lisp's `flet'. | |
e8693c96 GM |
1738 | In particular, in cl-flet function definitions are lexically scoped, |
1739 | whereas in flet the scoping is dynamic. | |
89660017 SM |
1740 | |
1741 | *** `cl-labels' is slightly different from `labels'. | |
823b2fb6 GM |
1742 | The difference is that it relies on the `lexical-binding' machinery |
1743 | (as opposed to the `lexical-let' machinery used previously) to capture | |
1744 | definitions in closures, so such closures will only work if `lexical-binding' | |
1745 | is in use. | |
89660017 | 1746 | |
f94b04fc | 1747 | *** `cl-letf' is not exactly like `letf'. |
4ddedf94 GM |
1748 | The only difference is in details that relate to some deprecated usage |
1749 | of `symbol-function' in place forms. | |
f94b04fc | 1750 | |
89660017 | 1751 | *** `progv' was rewritten to use the `let' machinery. |
823b2fb6 GM |
1752 | A side effect is that variables without corresponding values are bound |
1753 | to nil rather than being made unbound. | |
89660017 | 1754 | |
9512f820 GM |
1755 | *** The following methods of extending `setf' are obsolete |
1756 | (use features from gv.el instead): | |
1757 | `define-modify-macro' (use `gv-letplace') | |
031b2ea7 GM |
1758 | `defsetf' (use `gv-define-simple-setter' or `gv-define-setter') |
1759 | `define-setf-expander' (use `gv-define-setter' or `gv-define-expander') | |
2b4da3ff | 1760 | `get-setf-method' no longer exists (see "Incompatible Lisp Changes") |
f94b04fc | 1761 | |
6bc66c10 | 1762 | ** Diff mode |
f938eda9 | 1763 | |
6bc66c10 GM |
1764 | *** Changes are now highlighted using the same color scheme as in |
1765 | modern VCSes. Deletions are displayed in red (new faces | |
1766 | `diff-refine-removed' and `smerge-refined-removed', and new definition | |
1767 | of `diff-removed'), insertions in green (new faces `diff-refine-added' | |
1768 | and `smerge-refined-added', and new definition of `diff-added'). | |
f938eda9 | 1769 | |
6bc66c10 GM |
1770 | *** The variable `diff-use-changed-face' defines whether to use the |
1771 | face `diff-changed', or `diff-removed' and `diff-added' to highlight | |
1772 | changes in context diffs. | |
2f940384 | 1773 | |
6bc66c10 GM |
1774 | *** The new command `diff-delete-trailing-whitespace' removes trailing |

6bc66c10 GM |
2104 | ** SQL mode has a new option `sql-db2-escape-newlines'. |
2105 | If non-nil, newlines sent to the command interpreter will be escaped | |

2f940384 | 2149 | |
797e6e88 SM |
2150 | *** assoc.el |
2151 | In most cases, assoc+member+push+delq work just as well. | |
2152 | And in any case it's just a terrible package: ugly semantics, terrible | |
2153 | inefficiency, and not namespace-clean. | |

b4d3bc10 | 2163 | |
6bc66c10 GM |
2164 | ** Docstrings starting with `*' no longer indicate user options. |
2165 | Only variables defined using `defcustom' are considered user options. | |
2166 | The function `user-variable-p' is now an obsolete alias for | |
2167 | `custom-variable-p'. | |
090cf9db | 2168 | |
6bc66c10 GM |
2169 | ** The return values of `defalias', `defun' and `defmacro' have changed, |
2170 | and are now undefined. For backwards compatibility, `defun' and | |
2171 | `defmacro' currently return the name of the newly defined | |
2172 | function/macro, but this should not be relied upon. | |
090cf9db | 2173 | |
823b2fb6 GM |
2174 | ** `random' by default now returns a different random sequence in |
2175 | every Emacs run. Use `(random S)', where S is a string, to set the | |
0e23ef9d PE |
2176 | random seed to a value based on S, in order to get a repeatable |
2177 | sequence in later calls. | |
2178 | ||
d32e47af LM |
2179 | ** If the NEWTEXT arg to `replace-match' contains a substring "\?", |
2180 | that substring is inserted literally even if the LITERAL arg is | |
2181 | non-nil, instead of causing an error to be signaled. | |
2182 | ||
2cec368c MR |
2183 | ** `select-window' now always makes the window's buffer current. |
2184 | It does so even if the window was selected before. | |
2185 | ||
6bc66c10 GM |
2186 | ** The function `x-select-font' can return a font spec, instead of a |
2187 | font name as a string. Whether it returns a font spec or a font name | |
2188 | depends on the graphical library. | |
bbf908bc | 2189 | |
eeddc531 CY |
2190 | ** `face-spec-set' no longer sets frame-specific attributes when the |
2191 | third argument is a frame (that usage was obsolete since Emacs 22.2). | |
2192 | ||
6bc66c10 | 2193 | ** `set-buffer-multibyte' now signals an error in narrowed buffers. |
a59d531e | 2194 | |
ab7f1c43 GM |
2195 | ** The CL package's `get-setf-method' function no longer exists. |
2196 | Generalized variables are now part of core Emacs Lisp, and implemented | |
2197 | differently to the way cl.el used to do it. It is not possible to | |
2198 | define a compatible replacement for `get-setf-method'. See the file | |
2199 | gv.el for internal details of the new implementation. | |
2200 | ||
6bc66c10 GM |
2201 | ** The arguments of `dbus-register-signal' are no longer just strings, |
2202 | but keywords or keyword-string pairs. The old argument list will | |
2203 | still be supported for Emacs 24.x. | |
72b255c7 | 2204 | |
6bc66c10 | 2205 | ** Miscellaneous name changes |
823b2fb6 GM |
2206 | Some Lisp symbols have been renamed to correct their spelling, |
2207 | or to be more consistent with standard Emacs terminology. | |
72b255c7 | 2208 | |
72b255c7 | 2209 | *** Renamed functions |
72b255c7 PE |
2210 | **** hangul-input-method-inactivate -> hangul-input-method-deactivate |

2217 | **** ucs-input-inactivate -> ucs-input-deactivate | |
2218 | ||
2219 | *** Renamed hooks | |
2220 | The old hooks are still supported for backward compatibility, but they | |
2221 | are deprecated and will be removed eventually. | |
72b255c7 PE |
2222 | **** input-method-inactivate-hook -> input-method-deactivate-hook |
2223 | **** robin-inactivate-hook -> robin-deactivate-hook | |

02969baf | 2238 | *** `string-to-sequence' (use `string-to-list' or `string-to-vector') |
a5f2b6ec | 2239 | *** `compile-internal' |
02969baf | 2240 | *** `modeline' |
59f7af81 | 2241 | *** `mode-line-inverse-video' |

93e0bed6 | 2253 | * Lisp Changes in Emacs 24.3 |
ef24141c | 2254 | |
2ee3d7f0 | 2255 | ** CL-style generalized variables are now in core Elisp. |
f938eda9 | 2256 | `setf' is autoloaded; `push' and `pop' accept generalized variables. |
ebdbfb95 GM |
2257 | You can define your own generalized variables using `gv-define-simple-setter', |
2258 | `gv-define-setter', etc. | |
2ee3d7f0 | 2259 | |
6bc66c10 GM |
2260 | ** Emacs tries to macroexpand interpreted (non-compiled) files during load. |
2261 | This can significantly speed up execution of non-byte-compiled code, | |
2262 | but can also bump into previously unnoticed cyclic dependencies. | |
2263 | These are generally harmless: they will simply cause the macro calls | |
2264 | to be left for later expansion (as before), but will result in a | |
2265 | warning ("Eager macro-expansion skipped due to cycle") describing the cycle. | |
2266 | You may wish to restructure your code so this does not happen. | |
2267 | ||
2268 | ** New sampling-based Elisp profiler. | |
2269 | Try M-x profiler-start, do some work, and then call M-x profiler-report. | |
2270 | When finished, use M-x profiler-stop. The sampling rate can be based on | |
2271 | CPU time or memory allocations. | |
2272 | ||
500fcedc SM |
2273 | ** `defun' also accepts a (declare DECLS) form, like `defmacro'. |
2274 | The interpretation of the DECLS is determined by `defun-declarations-alist'. | |
2275 | ||
6bc66c10 GM |
2276 | ** New macros `setq-local' and `defvar-local'. |
2277 | ||
2278 | ** Face underlining can now use a wave. | |
2f940384 | 2279 | |
6bc66c10 | 2280 | ** `read-regexp' has a new argument HISTORY; the first argument PROMPT |
cd996018 | 2281 | of `read-regexp' accepts a string ending with a colon and space, and its |
823b2fb6 | 2282 | second argument DEFAULTS can be a list of strings accessible via `M-n' |
cd996018 CY |
2283 | in the minibuffer ahead of other hard-coded useful regexp-related values. |
2284 | More commands use `read-regexp' now to read their regexp arguments. | |
2285 | ||
f938eda9 | 2286 | ** Completion |
500fcedc | 2287 | |
f938eda9 CY |
2288 | *** New function `completion-table-with-quoting' to handle completion |
2289 | in the presence of quoting, such as file completion in shell buffers. | |
f95e9344 | 2290 | |
f938eda9 CY |
2291 | *** New function `completion-table-subvert' to use an existing completion |
2292 | table, but with a different prefix. | |
2293 | ||
6bc66c10 | 2294 | ** Debugger |
f95e9344 | 2295 | |
f938eda9 CY |
2296 | *** New error type and new function `user-error'. |
2297 | These do not trigger the debugger. | |
f95e9344 | 2298 | |
57fc0fee GM |
2299 | *** New option `debugger-bury-or-kill', saying what to do with the |
2300 | debugger buffer when exiting debug. | |
45b82ad0 SM |
2301 | |
2302 | *** Set `debug-on-message' to enter the debugger when a certain | |
2303 | message is displayed in the echo area. This can be useful when trying | |
2304 | to work out which code is doing something. | |
2f940384 | 2305 | |
45b82ad0 SM |
2306 | *** New var `inhibit-debugger', automatically set to prevent accidental |
2307 | recursive invocations. | |
fa2bcf43 | 2308 | |
6bc66c10 | 2309 | ** Window handling |
2f940384 | 2310 | |
6bc66c10 GM |
2311 | *** New command `fit-frame-to-buffer' adjusts the frame height to |
2312 | fit the contents. | |
2f940384 | 2313 | |
6bc66c10 GM |
2314 | *** The command `fit-window-to-buffer' can adjust the frame height |
2315 | if the new option `fit-frame-to-buffer' is non-nil. | |
8e17c9ba | 2316 | |
7fe37cfc GM |
2317 | *** New macro `with-temp-buffer-window', similar to |
2318 | `with-output-to-temp-buffer'. | |
fa2bcf43 | 2319 | |
8e17c9ba MR |
2320 | *** `temp-buffer-resize-mode' no longer resizes windows that have been |
2321 | reused. | |
c5e28e39 | 2322 | |
823b2fb6 | 2323 | *** New option `switch-to-buffer-preserve-window-point' to restore a |
43bcfda6 | 2324 | window's point when switching buffers. |
7c82753d | 2325 | |
6bc66c10 GM |
2326 | *** New display action alist entries `window-height' and `window-width' |
2327 | specify the size of new windows created by `display-buffer'. | |
2328 | ||
2329 | *** New display action alist entry `pop-up-frame-parameters', if | |
2330 | non-nil, specifies frame parameters to give any newly-created frame. | |
7c82753d | 2331 | |
fa2bcf43 MR |
2332 | *** New display action alist entry `inhibit-switch-frame', if non-nil, |
2333 | tells display action functions to avoid changing which frame is | |
2334 | selected. | |
2f940384 | 2335 | |
fa2bcf43 MR |
2336 | *** New display action alist entry `previous-window', if non-nil, |
2337 | specifies window to reuse in `display-buffer-in-previous-window'. | |
2f940384 | 2338 | |
6bc66c10 GM |
2339 | *** New display action functions `display-buffer-below-selected', |
2340 | and `display-buffer-in-previous-window'. | |
2341 | ||
2342 | *** The functions `get-lru-window', `get-mru-window' and `get-largest-window' | |
2343 | now accept a third argument to avoid choosing the selected window. | |
2344 | ||
2345 | *** Additional values recognized for option `window-combination-limit'. | |
5938d519 | 2346 | |
77f1f99c CY |
2347 | *** The following variables are obsolete, as they can be replaced by |
2348 | appropriate entries in the `display-buffer-alist' function introduced | |
2349 | in Emacs 24.1: | |
823b2fb6 | 2350 | **** `dired-shrink-to-fit' |
77f1f99c | 2351 | **** `display-buffer-reuse-frames' |
823b2fb6 | 2352 | **** `display-buffer-function' |
77f1f99c | 2353 | **** `special-display-buffer-names' |
823b2fb6 | 2354 | **** `special-display-frame-alist' |

823b2fb6 | 2356 | **** `special-display-regexps' |
77f1f99c | 2357 | |
ab0fa4e4 | 2358 | ** Time |
2f940384 | 2359 | |
ab0fa4e4 PE |
2360 | *** `current-time-string' no longer requires that its argument's year |
2361 | must be in the range 1000..9999. It now works with any year supported | |
2362 | by the underlying C implementation. | |
2f940384 | 2363 | |
f938eda9 CY |
2364 | *** `current-time' now returns extended-format time stamps |
2365 | (HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds. | |
2366 | PSEC is typically a multiple of 1000 on current machines. Other | |
823b2fb6 GM |
2367 | functions that use this format, such as `file-attributes' and |
2368 | `format-time-string', have been changed accordingly. Old-format time | |
f938eda9 | 2369 | stamps are still accepted. |
2f940384 | 2370 | |
823b2fb6 | 2371 | *** The format of timers in `timer-list' and `timer-idle-list' is now |
f938eda9 CY |
2372 | [TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS]. |
2373 | The PSECS slot is new, and uses picosecond resolution. It can be | |
823b2fb6 | 2374 | accessed via the new `timer--psecs' accessor. |
2f940384 | 2375 | |
c4132fd4 PE |
2376 | *** Last-modified time stamps in undo lists now are of the form |
2377 | (t HI-SECS LO-SECS USECS PSECS) instead of (t HI-SECS . LO-SECS). | |
2378 | ||
0058cae2 GM |
2379 | ** EIEIO |
2380 | ||
2381 | *** Improved security when handling persistent objects: | |
2382 | ||
2383 | **** `eieio-persistent-read' now features optional arguments for specifying | |
2384 | the class to load, as well as a flag stating whether subclasses are allowed; | |
2385 | if provided, other classes will be rejected by the reader. For | |
2386 | compatibility with existing code, if the class is omitted only a | |
2387 | warning is issued. | |
2388 | ||
2389 | **** New specialized reader for pulling in classes and signaling errors | |
2390 | without evaluation of suspicious code. | |
2391 | ||
2392 | **** All slots that contain objects must have a :type. Slots with lists | |
2393 | of objects must use a new type predicate for a list of an object type. | |
2394 | ||
2395 | *** Support for `find-function' and similar utilities, through the addition | |
2396 | of filename support to generated symbols. | |
2397 | ||
f938eda9 | 2398 | ** Floating point functions now always return special values like NaN, |
823b2fb6 | 2399 | instead of signaling errors, if given invalid args; e.g., (log -1.0). |
f938eda9 CY |
2400 | Previously, they returned NaNs on some platforms but signaled errors |
2401 | on others. The affected functions are acos, asin, tan, exp, expt, | |
2402 | log, log10, sqrt, and mod. | |
2403 | ||
6bc66c10 | 2404 | ** New fringe bitmap `exclamation-mark'. |
f938eda9 | 2405 | |
6bc66c10 GM |
2406 | ** Miscellaneous changes to special forms and macros |
2407 | ||
2408 | *** `defun' and `defmacro' are now macros rather than special forms. | |
2409 | ||
2410 | *** `kbd' is now a function rather than a macro. | |
2411 | ||
2412 | ** Miscellaneous new functions | |
2413 | ||
b29daf07 GM |
2414 | *** `set-temporary-overlay-map' sets up a temporary keymap that |
2415 | takes precedence over most other maps for a short while (normally one key). | |
f938eda9 | 2416 | |
847a0561 | 2417 | *** `autoloadp' tests if its argument is an autoloaded object. |
2f940384 | 2418 | |
847a0561 | 2419 | *** `autoload-do-load' performs the autoloading operation. |
2f940384 | 2420 | |
f938eda9 | 2421 | *** `buffer-narrowed-p' tests if the buffer is narrowed. |
2f940384 | 2422 | |
f938eda9 | 2423 | *** `file-name-base' returns a file name sans directory and extension. |
2f940384 | 2424 | |
f938eda9 | 2425 | *** `function-get' fetches a function property, following aliases. |
c990426a | 2426 | |
f938eda9 | 2427 | *** `posnp' tests if an object is a `posn'. |
f938eda9 | 2428 | |
f938eda9 | 2429 | *** `system-users' returns the user names on the system. |
547d6865 | 2430 | |
f938eda9 | 2431 | *** `system-groups' returns the group names on the system. |
f938eda9 | 2432 | |
f938eda9 | 2433 | *** `tty-top-frame' returns the topmost frame of a text terminal. |
c990426a | 2434 | |
f938eda9 | 2435 | ** The following functions and variables are obsolete: |
847a0561 | 2436 | *** `automount-dir-prefix' (use `directory-abbrev-alist') |
f938eda9 | 2437 | *** `buffer-has-markers-at' |
1a9c6830 | 2438 | *** `macro-declaration-function' (use `macro-declarations-alist') |
847a0561 | 2439 | *** `window-system-version' (provides no useful information) |
93cacb6d | 2440 | *** `dired-pop-to-buffer' (use `dired-mark-pop-up') |
0e2ae83d | 2441 | *** `query-replace-interactive' |
49238e7f | 2442 | *** `font-list-limit' (has had no effect since Emacs < 23) |

9078ead6 | 2446 | |
4e98ad15 | 2447 | ** Cygwin builds can use the native MS Windows user interface. |
823b2fb6 | 2448 | Pass `--with-w32' to configure. The default remains the X11 interface. |
53a63be6 | 2449 | |
1a9c6830 | 2450 | ** Two new functions are available in Cygwin builds: |
6e9f7997 DC |
2451 | `cygwin-convert-file-name-from-windows' and |
2452 | `cygwin-convert-file-name-to-windows'. These functions allow Lisp | |
2453 | code to access the Cygwin file-name mapping machinery to convert | |
2454 | between Cygwin and Windows-native file and directory names. | |
de6e3a60 | 2455 | |
4e98ad15 | 2456 | ** When invoked with the -nw switch to run on the Windows text-mode terminal, |
1ab0c851 | 2457 | Emacs now supports `mouse-highlight', help-echo (in the echo area), and |
4e98ad15 GM |
2458 | `mouse-autoselect-window'. |
2459 | ||
1a9c6830 | 2460 | ** On MS Windows Vista and later Emacs now supports symbolic links. |
4e98ad15 | 2461 | |
823b2fb6 | 2462 | ** On MS Windows, you can pass `--without-libxml2' to configure.bat to omit |
4e98ad15 GM |
2463 | support for libxml2, even if its presence is detected. |
2464 | ||
4e98ad15 GM |
2465 | ** On Mac OS X, the Nextstep port requires OS X 10.4 or later. |

eb199145 | 2476 | * Installation Changes in Emacs 24.1 |
09e18d03 | 2477 | |
31fd3586 GM |
2478 | ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
2479 | to configure. Note that other libraries used by Emacs, RSVG and GConf, | |
2480 | also depend on Gtk+. You can disable them with --without-rsvg and | |
2481 | --without-gconf. | |
338648ad | 2482 | |
31fd3586 GM |
2483 | ** Emacs can be compiled with GnuTLS support. |
2484 | This happens by default if a suitably recent version of the library is | |
2485 | found at build time. To prevent this, use the configure option | |
2486 | `--without-gnutls'. See below for GnuTLS features. | |
338648ad | 2487 | |
31fd3586 GM |
2488 | ** Emacs can be compiled with SELinux support. |
2489 | This happens by default if a suitably recent version of the library is | |
2490 | found at build time. To prevent this, use the configure option | |
2491 | `--without-selinux'. See below for SELinux features. | |
aded53ff | 2492 | |
31fd3586 GM |
2493 | ** Emacs can be compiled with ImageMagick support. |
2494 | This happens by default if a suitably recent version of the library is | |
2495 | found at build time. To prevent this, use the configure option | |
2496 | `--without-imagemagick'. See below for ImageMagick features. | |
c1f10868 | 2497 | This feature is not available for the Nextstep or MS ports. |
d9170db5 | 2498 | |
043efd56 GM |
2499 | ** Emacs can be compiled with libxml2 support. |
2500 | This happens by default if a suitably recent version of the library is | |
2501 | found at build time. To prevent this, use the configure option | |
2502 | `--without-xml2'. See below for libxml2 features. | |
2503 | ||
7d301ae6 CY |
2504 | ** By default, the installed Info and man pages are compressed. |
2505 | You can disable this by configuring --without-compress-info. | |
2506 | ||
7d301ae6 | 2507 | ** New configure option --with-wide-int. |
81eafe29 | 2508 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. |
0a768890 PE |
2509 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB |
2510 | to about 2 GiB. | |
81eafe29 | 2511 | |
7d301ae6 | 2512 | ** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost. |
31fd3586 GM |
2513 | These provide no new functionality, they just remove the need to edit |
2514 | lib-src/Makefile by hand in order to use the associated features. | |
2515 | ||
7d301ae6 | 2516 | ** New configure option --enable-use-lisp-union-type. |
31fd3586 GM |
2517 | This is only useful for Emacs developers to debug certain types of bugs. |
2518 | This is not a new feature; only the configure flag is new. | |
041d709f CY |
2519 | |
2520 | ** The standalone programs digest-doc and sorted-doc are removed. | |
2521 | Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'. | |
2522 | ||
041d709f CY |
2523 | ** The standalone program `fakemail' is removed. |
2524 | If you need it, feedmail.el provides a superset of the functionality. | |
2525 | ||
0bfd685e | 2526 | \f |
eb199145 | 2527 | * Startup Changes in Emacs 24.1 |
4a263588 | 2528 | |
198a7a97 | 2529 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte |
adbf62ff GM |
2530 | command line arguments, and the EMACS_UNIBYTE environment variable, no |
2531 | longer have any effect. (They were declared obsolete in Emacs 23.) | |
198a7a97 | 2532 | |
66b7b0fe | 2533 | ** New command line option `--no-site-lisp' removes site-lisp directories |
1b5e5b0c GM |
2534 | from load-path. -Q now implies this. This option does not affect the |
2535 | EMACSLOADPATH environment variable (and hence has no effect for | |
c8d59ba3 | 2536 | Nextstep builds). |
66b7b0fe | 2537 | |
0bfd685e | 2538 | \f |
eb199145 | 2539 | * Changes in Emacs 24.1 |
7841339b | 2540 | |
a2a25d24 | 2541 | ** Completion |
fdeb32ec | 2542 | |
dfdb4cad CY |
2543 | *** Many packages now use the `completion-at-point' command, |
2544 | rather than implementing separate completion commands. | |
2545 | ||
de0bde62 | 2546 | *** `completion-at-point' now handles tags and semantic completion. |
dfdb4cad | 2547 | |
a2a25d24 SM |
2548 | *** Completion in a non-minibuffer now tries to detect the end of completion |
2549 | and pops down the *Completions* buffer accordingly. | |
dfdb4cad CY |
2550 | |
2551 | *** New option `completion-cycle-threshold' allows completion cycling. | |
2552 | ||
2553 | *** New option `completion-category-overrides' for overriding the | |
2c719188 | 2554 | default completion style in certain circumstances. |
dfdb4cad | 2555 | |
a2a25d24 | 2556 | *** New completion style `substring'. |
dfdb4cad CY |
2557 | |
2558 | *** Completion of buffer names uses `substring' completion by default. | |
2559 | ||
2560 | *** The option `widget-complete-field' has been removed. | |
620c53a6 | 2561 | |
6870aaef | 2562 | ** Mail changes |
dfdb4cad | 2563 | |
7d301ae6 CY |
2564 | *** The first time you try sending mail, Emacs asks for a mail method. |
2565 | This is implemented by a new default for `send-mail-function', which | |
2566 | is `sendmail-query-once'. This offers to use the smtpmail package, or | |
2567 | to use the old defaults relying on external mail facilities | |
2568 | (`sendmail-send-it' on GNU/Linux and other Unix-like systems, and | |
2569 | `mailclient-send-it' on Windows). | |
dfdb4cad | 2570 | |
e78e7e48 CY |
2571 | *** Typing `C-c m' in the buffer made by `M-x report-emacs-bug' |
2572 | transfers the report to your desktop's preferred mail client, if there | |
2573 | is one. This uses either the "xdg-email" utility, or Mac OS's "open" | |
2574 | command. | |
dfdb4cad | 2575 | |
7d301ae6 CY |
2576 | *** See Changes in Specialized Modes and Packages for SMTPmail changes |
2577 | and Mail mode changes | |
3f88cd72 | 2578 | |
041d709f | 2579 | ** Emacs server and client changes |
dfdb4cad | 2580 | |
7d301ae6 | 2581 | *** New option `server-port' specifies the port for TCP Emacs servers. |
dfdb4cad | 2582 | |
041d709f | 2583 | *** New emacsclient argument -q/--quiet suppresses some status messages. |
dfdb4cad | 2584 | |
7d301ae6 CY |
2585 | *** New emacsclient argument --frame-parameters specifies the frame |
2586 | parameters of any newly-created graphical frame. | |
dfdb4cad CY |
2587 | |
2588 | *** If emacsclient shuts down due to Emacs signaling an error, | |
2589 | its exit status is 1. | |
2590 | ||
041d709f CY |
2591 | *** New emacsclient argument --parent-id ID. |
2592 | This opens a client frame in parent X window ID, via XEmbed, similar | |
2593 | to the --parent-id argument to Emacs. | |
2594 | ||
d0ce9f8c MB |
2595 | ** Internationalization changes |
2596 | ||
d0ce9f8c | 2597 | *** Emacs now supports display and editing of bidirectional text. |
7d301ae6 CY |
2598 | Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are |
2599 | displayed in the correct visual order as expected by users of those | |
dfdb4cad CY |
2600 | scripts. The display reordering is a "full bidirectionality" class |
2601 | implementation of the Unicode Bidirectional Algorithm (UBA). Buffers | |
2602 | with no RTL text should look exactly the same as before. | |
f4b6ba46 | 2603 | |
041d709f | 2604 | **** New buffer-local variable `bidi-display-reordering'. |
7d301ae6 | 2605 | To disable display reordering in a buffer, change this to nil. |
d20e1419 | 2606 | |
041d709f CY |
2607 | **** New buffer-local variable `bidi-paragraph-direction'. |
2608 | If nil (the default), Emacs determines the base direction of each | |
dfdb4cad CY |
2609 | paragraph from its text, as specified by the UBA. Setting the value |
2610 | to `right-to-left' or `left-to-right' forces a base direction on each | |
2611 | paragraph. | |
f4b6ba46 | 2612 | |
7d301ae6 CY |
2613 | Paragraphs with right-to-left base direction are displayed starting at |
2614 | the right window edge. | |
f1816485 | 2615 | |
dfdb4cad CY |
2616 | *** Enhanced support for characters with no glyphs in available fonts, |
2617 | or, on text terminals, characters that cannot be encoded by the | |
2618 | terminal coding system. The new option `glyphless-char-display-control' | |
2619 | specifies how to display them: as a hexadecimal code in a box, a thin | |
2620 | 1-pixel space, an empty box, etc. | |
d0ce9f8c | 2621 | |
9702b7a1 GM |
2622 | *** New input methods for Farsi and Bulgarian |
2623 | (farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic). | |
041d709f | 2624 | |
939db9ac CY |
2625 | *** `nobreak-char-display' now also highlights Unicode hyphen chars |
2626 | (U+2010 and U+2011). | |
2627 | ||
7d301ae6 | 2628 | *** New Hebrew translation of the Emacs Tutorial. |
31fd3586 GM |
2629 | Type `C-u C-h t' to choose it in case your language setup doesn't |
2630 | automatically select it. | |
2631 | ||
7d301ae6 CY |
2632 | ** An Emacs Lisp package manager is now included. |
2633 | This is a convenient way to download and install additional packages, | |
2634 | from a package repository at http://elpa.gnu.org. | |
dfdb4cad | 2635 | |
7d301ae6 CY |
2636 | *** M-x list-packages shows a list of packages, which can be |
2637 | selected for installation. | |
dfdb4cad | 2638 | |
7d301ae6 | 2639 | *** New command `describe-package', bound to `C-h P'. |
dfdb4cad | 2640 | |
7d301ae6 CY |
2641 | *** By default, all installed packages are loaded automatically when |
2642 | Emacs starts up. To disable this, set `package-enable-at-startup' to | |
2643 | nil. To specify the packages to load, customize `package-load-list'. | |
16a91140 | 2644 | |
dfdb4cad CY |
2645 | ** Custom theme changes |
2646 | ||
7d301ae6 CY |
2647 | *** New command `M-x customize-themes', which provides a convenient |
2648 | interface for enabling and disabling Custom themes. | |
dfdb4cad | 2649 | |
7d301ae6 | 2650 | *** New option `custom-theme-load-path' is the load path for themes. |
dfdb4cad CY |
2651 | Emacs no longer looks for Custom themes in `load-path'. The default |
2652 | value of `custom-theme-load-path' says to look for themes in | |
2653 | `custom-theme-directory', followed by a subdirectory of | |
2654 | `data-directory' named "themes/", which contains a small selection of | |
2655 | built-in Custom themes. | |
2656 | ||
7d301ae6 CY |
2657 | *** New option `custom-safe-themes' records known-safe theme files. |
2658 | If a theme is not in this list, Emacs queries before loading it, and | |
2659 | offers to save the theme to `custom-safe-themes' automatically. By | |
2660 | default, all themes included in Emacs are treated as safe. | |
b7d65a5f | 2661 | |
7d301ae6 | 2662 | ** Improved GTK integration |
dfdb4cad | 2663 | |
7d301ae6 | 2664 | *** GTK scroll-bars are now placed on the right by default. |
dfdb4cad CY |
2665 | The function `set-scroll-bar-mode' can change this. |
2666 | ||
7d301ae6 | 2667 | *** GTK tool bars can have just text, just images or images and text. |
dfdb4cad CY |
2668 | Customize `tool-bar-style' to choose the style. On a Gnome desktop, |
2669 | the default is taken from desktop settings. | |
2670 | ||
2671 | *** GTK tool bars can be placed on any edge of the frame. | |
7d301ae6 CY |
2672 | The frame-parameter tool-bar-position controls this. It takes the |
2673 | values top, left, right or bottom. The Options => Show/Hide menu has | |
2674 | entries for this. | |
dfdb4cad | 2675 | |
7d301ae6 CY |
2676 | *** The default colors for selected text (the `region' face) are taken |
2677 | from the GTK theme when Emacs is built with GTK. | |
dfdb4cad | 2678 | |
7d301ae6 CY |
2679 | *** Emacs uses GTK tooltips by default if built with GTK. |
2680 | You can disable this by changing `x-gtk-use-system-tooltips' to nil. | |
a5bee597 | 2681 | |
dfdb4cad CY |
2682 | ** Graphical interface changes |
2683 | ||
2684 | *** On graphical displays, the mode-line no longer ends in dashes. | |
2685 | Also, the first dash (which does not indicate anything) is just | |
2686 | displayed as a space. | |
2687 | ||
2688 | *** `menu-bar-select-buffer-function' lets you choose another operation | |
2689 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. | |
2690 | ||
2691 | *** Lucid menus and dialogs can display antialiased fonts if Emacs is | |
2692 | built with Xft. These fonts can be set via X resources, for example: | |
2693 | Emacs.pane.menubar.font: Courier-12 | |
2694 | ||
7d301ae6 | 2695 | ** Exiting changes |
dfdb4cad | 2696 | |
7d301ae6 | 2697 | *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP, |
dfdb4cad CY |
2698 | or if it receives a SIGINT signal in batch mode. |
2699 | ||
7d301ae6 CY |
2700 | *** `kill-emacs-hook' is now also run in batch mode. |
2701 | Third-party code which adds to `kill-emacs-hook' should check if they | |
2702 | do the right thing in batch mode. | |
9c524fcb | 2703 | |
041d709f | 2704 | ** Scrolling changes |
dfdb4cad | 2705 | |
041d709f | 2706 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' |
0a19a6f8 | 2707 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
7d301ae6 | 2708 | of buffer at first key-press (instead they move to top/bottom of buffer) |
550f41cd | 2709 | when `scroll-error-top-bottom' is non-nil. |
dfdb4cad CY |
2710 | |
2711 | *** New option `scroll-error-top-bottom' (see above). | |
2712 | ||
041d709f | 2713 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' |
5a97d2da | 2714 | scroll a line instead of full screen. |
dfdb4cad | 2715 | |
041d709f | 2716 | *** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 2717 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
dfdb4cad | 2718 | |
041d709f | 2719 | *** If you customize `scroll-conservatively' to a value greater than 100, |
d0f69533 EZ |
2720 | Emacs will never recenter point in the window when it scrolls due to |
2721 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | |
2722 | Previously, you needed to use `most-positive-fixnum' as the value of | |
2723 | `scroll-conservatively' to achieve the same effect. | |
dfdb4cad | 2724 | |
7d301ae6 | 2725 | *** "Aggressive" scrolling now honors the scroll margins. |
d0f69533 EZ |
2726 | If you customize `scroll-up-aggressively' or |
2727 | `scroll-down-aggressively' and move point off the window, Emacs now | |
2728 | scrolls the window so as to avoid positioning point inside the scroll | |
2729 | margin. | |
2730 | ||
7d301ae6 CY |
2731 | ** Basic SELinux support has been added. |
2732 | This requires Emacs to be linked with libselinux at build time. | |
f1a5d776 | 2733 | |
dfdb4cad CY |
2734 | *** Emacs preserves the SELinux file context when backing up. |
2735 | Also, the function `copy-file' has an extra optional argument for | |
2736 | preserving SELinux context, and the return value of `backup-buffer' | |
2737 | now includes the SELinux context. | |
f0bf7c8e | 2738 | |
dfdb4cad | 2739 | *** New functions `file-selinux-context' and `set-file-selinux-context' |
7d301ae6 | 2740 | get and set the SELinux context of a file. |
44198b6e | 2741 | |
7d301ae6 | 2742 | ** Trash changes |
dfdb4cad | 2743 | |
7d301ae6 CY |
2744 | *** `delete-by-moving-to-trash' now only affects commands that specify |
2745 | trashing. This avoids inadvertently trashing temporary files. | |
dfdb4cad | 2746 | |
7d301ae6 CY |
2747 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
2748 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
278f6845 | 2749 | |
041d709f | 2750 | ** File- and directory-local variable changes |
dfdb4cad | 2751 | |
041d709f CY |
2752 | *** You can stop directory local vars from applying to subdirectories. |
2753 | Add an element (subdirs . nil) to the alist portion of any variables | |
2754 | settings to indicate that the section should not apply to | |
2755 | subdirectories. | |
dfdb4cad | 2756 | |
041d709f CY |
2757 | *** Directory local variables can apply to some file-less buffers. |
2758 | Affected modes include dired, vc-dir, and log-edit. For example, | |
2759 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will | |
2760 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call | |
2761 | `hack-dir-local-variables-non-file-buffer' to support this. | |
dfdb4cad | 2762 | |
041d709f CY |
2763 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. |
2764 | Instead, use "eval: (minor-mode 1)". | |
c136e5cd | 2765 | |
7b447e9b GM |
2766 | *** The variable `inhibit-first-line-modes-regexps' has been renamed |
2767 | to `inhibit-local-variables-regexps'. As the name suggests, it now | |
dfdb4cad CY |
2768 | applies to ALL file local variables, not just -*- lines. The |
2769 | associated `inhibit-first-line-modes-suffixes' has been renamed in the | |
2770 | corresponding way. | |
5d907d6c | 2771 | |
0a2132ba CY |
2772 | ** Window changes |
2773 | ||
91b65361 CY |
2774 | *** The `quit-window' command now restores the last buffer displayed |
2775 | in the quitted window. | |
2776 | ||
0a2132ba CY |
2777 | *** Resizing an Emacs frame now preserves proportional window sizes, |
2778 | modulo restrictions like window minimum sizes and fixed-size windows. | |
2779 | ||
2780 | *** The behavior of `display-buffer' is now customizable in detail. | |
dfdb4cad | 2781 | |
0a2132ba CY |
2782 | **** New option `display-buffer-base-action' specifies a list of |
2783 | user-determined display "actions" (functions and optional arguments | |
2784 | for choosing the displaying window). | |
2785 | ||
2786 | This takes precedence over the default display action, which is | |
2787 | specified by `display-buffer-fallback-action'. | |
2788 | ||
2789 | **** New option `display-buffer-alist' maps buffer name regexps to | |
2790 | display actions, taking precedence over `display-buffer-base-action'. | |
2791 | ||
a0c2d0ae MR |
2792 | *** New option `window-combination-limit'. |
2793 | The new option `window-combination-limit' allows to return the space | |
2794 | obtained for resizing or creating a window more reliably to the window | |
2795 | from which such space was obtained. | |
0a2132ba | 2796 | |
a0c2d0ae MR |
2797 | *** New option `window-combination-resize'. |
2798 | The new option `window-combination-resize' allows to split a window that | |
2799 | otherwise cannot be split because it's too small by stealing space from | |
2800 | other windows in the same combination. Subsequent resizing or deletion | |
2801 | of the window will resize all windows in the same combination as well. | |
0a2132ba | 2802 | |
91b65361 CY |
2803 | *** New option `frame-auto-hide-function' lets you choose between |
2804 | iconifying or deleting a frame when burying a buffer in a dedicated | |
2805 | frame, or quitting a window showing a buffer in a frame of its own. | |
2806 | ||
0a2132ba | 2807 | *** New commands `maximize-window' and `minimize-window'. |
53964682 | 2808 | These maximize and minimize the size of a window within its frame. |
0a2132ba | 2809 | |
0a2132ba CY |
2810 | *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'. |
2811 | These functions allow to navigate through the live buffers that have | |
2812 | been shown in a specific window. | |
2813 | ||
7d301ae6 | 2814 | ** Minibuffer changes |
dfdb4cad | 2815 | |
7d301ae6 | 2816 | *** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. |
104dc9c6 GM |
2817 | This is handy for minibuffer-only frames, and is also used for the feature |
2818 | where mouse-1 pops up *Messages*"', which can now easily be changed. | |
041d709f | 2819 | |
7d301ae6 | 2820 | *** Minibuffers set `truncate-lines' to nil. |
f66eca26 | 2821 | If you want to change the value to something else, you could use |
7d301ae6 CY |
2822 | for example `minibuffer-setup-hook'. |

7d301ae6 CY |

2828 | ** New basic faces `error', `warning', `success'. |
2829 | These are used to highlight text indicating failure, caution or | |
2830 | successful operation. | |
2831 | ||
2832 | ** New option `list-colors-sort' defines the color sort order | |
2833 | for `list-colors-display'. | |

892777ba | 2840 | ** Search changes |
dfdb4cad CY |
2841 | |
2842 | *** C-y in Isearch is now bound to `isearch-yank-kill', instead of | |
2843 | `isearch-yank-line'. | |
2844 | ||
2845 | *** M-y in Isearch is now bound to `isearch-yank-pop', instead of | |
2846 | `isearch-yank-kill'. | |
2847 | ||
2848 | *** M-s C-e in Isearch is now bound to `isearch-yank-line'. | |
2849 | ||
b2b0776e | 2850 | ** New commands `count-words-region' and `count-words'. |
dfdb4cad | 2851 | |
10607bea CY |
2852 | *** M-= is bound to `count-words-region', not `count-lines-region'. |
2853 | The `count-words-region' command, when called interactively, reports | |
2854 | the number of lines, words, and characters in the region. It is a | |
2855 | superset of the old `count-lines-region', which is now an obsolete | |
2856 | alias for it. | |
ea4f7750 | 2857 | |
ec9da840 | 2858 | ** The command `just-one-space' (M-SPC), if given a negative argument, |
1c708c1a CY |
2859 | also deletes newlines around point. |
2860 | ||
b9229673 | 2861 | ** Deletion changes |
dfdb4cad | 2862 | |
b9229673 | 2863 | *** New option `delete-active-region'. |
ddb54206 | 2864 | If non-nil, [delete] and DEL delete the region if it is active and no |
dfdb4cad | 2865 | prefix argument is given. If set to `kill', those commands kill |
ddb54206 | 2866 | instead. |
dfdb4cad | 2867 | |
59ee0542 | 2868 | *** New command `delete-forward-char', bound to [delete]. |
42d9cffa CY |
2869 | This is meant for interactive use, and obeys `delete-active-region'. |
2870 | The command `delete-char' does not obey `delete-active-region'. | |
dfdb4cad | 2871 | |
b9229673 CY |
2872 | *** `delete-backward-char' is now a Lisp function. |
2873 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
7d301ae6 CY |
2874 | However, the byte compiler now warns if it is called from Lisp; Lisp |
2875 | callers should use delete-char with a negative argument instead. | |
dfdb4cad | 2876 | |
b9229673 CY |
2877 | *** The option `mouse-region-delete-keys' has been deleted. |
2878 | ||
f9d71b42 CY |
2879 | ** Selection changes. |
2880 | ||
7d301ae6 CY |
2881 | The default handling of clipboard and primary selections has been |
2882 | changed to conform with modern X applications. In short, most | |
2883 | commands for killing and yanking text now use the clipboard, while | |
2884 | mouse commands use the primary selection. | |
b1ab31ae CY |
2885 | |
2886 | In the following, we provide a list of these changes, followed by a | |
2887 | list of steps to get the old behavior back if you prefer that. | |
2888 | ||
b1ab31ae CY |
2889 | *** `select-active-regions' now defaults to t. |
2890 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
963578d3 | 2891 | the kill ring. The selected text is put in the primary selection, if |
b1ab31ae CY |
2892 | the system possesses a separate primary selection facility (e.g. X). |
2893 | ||
2894 | **** `select-active-regions' also accepts a new value, `only'. | |
2895 | This means to only set the primary selection for temporarily active | |
2896 | regions (usually made by mouse-dragging or shift-selection); | |
2897 | "ordinary" active regions, such as those made with C-SPC followed by | |
2898 | point motion, do not alter the primary selection. | |
2899 | ||
963578d3 CY |
2900 | **** `mouse-drag-copy-region' now defaults to nil. |
2901 | ||
b1ab31ae CY |
2902 | *** mouse-2 is now bound to `mouse-yank-primary'. |
2903 | This pastes from the primary selection, ignoring the kill-ring. | |
2904 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
dfdb4cad | 2905 | |
b1ab31ae | 2906 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
dfdb4cad | 2907 | |
b1ab31ae CY |
2908 | *** `x-select-enable-primary' now defaults to nil. |
2909 | Thus, commands that kill text or copy it to the kill-ring (such as | |
2910 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
2911 | ||
2912 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now | |
dfdb4cad | 2913 | exactly equivalent to M-w, C-w, and C-y respectively. |
b1ab31ae CY |
2914 | |
2915 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already | |
2916 | non-nil by default, as Windows does not support the primary selection | |
2917 | between applications. | |
2918 | ||
2919 | *** To return to the previous behavior, do the following: | |
dfdb4cad | 2920 | |
104c2fe9 | 2921 | **** Change `select-active-regions' to nil. |
b1ab31ae CY |
2922 | **** Change `mouse-drag-copy-region' to t. |
2923 | **** Change `x-select-enable-primary' to t (on X only). | |
2924 | **** Change `x-select-enable-clipboard' to nil. | |
2925 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 2926 | |
084e6df3 | 2927 | *** Support for X cut buffers has been removed. |
dfdb4cad | 2928 | |
3fd50d5c CY |
2929 | *** X clipboard managers are now supported. |
2930 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. | |
4b80f674 | 2931 | |
dfdb4cad CY |
2932 | ** New command `C-x r N' (`rectangle-number-lines') numbers the lines |
2933 | in the current rectangle. With a prefix argument, this prompts for a | |
2934 | number to count from and for a format string. | |
99f053cf | 2935 | |
7d301ae6 | 2936 | ** `redisplay-dont-pause' now defaults to t. |
6bf7006f EZ |
2937 | This makes Emacs feel more responsive to editing commands that arrive |
2938 | at high rate, e.g. if you lean on some key, because stopping redisplay | |
2939 | in the middle (when this variable is nil) forces more expensive | |
2940 | updates later on, and Emacs appears to be unable to keep up. | |
2941 | ||
e70b5064 CY |
2942 | ** The behavior of <TAB> for active regions in Text mode has changed. |
2943 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | |
2944 | when the region is active causes Emacs to indent all the lines in the | |
2945 | region, aligning them with the line previous to the first line in the | |
2946 | region (or with the left margin if there is no previous line). | |
2947 | ||
dfdb4cad CY |
2948 | ** When `occur' is called with a prefix argument, matching strings are |
2949 | collected into the `*Occur*' buffer without line numbers. If there | |
2950 | are parenthesized subexpressions in the specified regexp, `occur' | |
2951 | reads replacement text that may contain \\& and \\N whose convention | |
2952 | follows `replace-match'. | |

b7c3692a | 2959 | ** BibTeX mode |
dfdb4cad | 2960 | |
2de69e00 | 2961 | *** BibTeX mode now supports biblatex. |
7d301ae6 CY |
2962 | Use the variable `bibtex-dialect' to select different BibTeX dialects. |
2963 | `bibtex-entry-field-alist' is now an obsolete alias for | |
2964 | `bibtex-BibTeX-entry-alist'. | |
2965 | ||
dfdb4cad CY |
2966 | *** New command `bibtex-search-entries', bound to C-c C-a. |
2967 | ||
b7c3692a | 2968 | *** New `bibtex-entry-format' option `sort-fields', disabled by default. |
dfdb4cad | 2969 | |

7d301ae6 | 2972 | ** Browse-url |
dfdb4cad | 2973 | |
7d301ae6 | 2974 | *** New option `browse-url-mailto-function' specifies how to handle "mailto:"s. |
dfdb4cad | 2975 | |
7d301ae6 CY |
2976 | *** The default browser used by the package is now the "xdg-open" program, |
2977 | on platforms that support it. This calls your desktop's preferred browser. | |
2978 | ||
86e100a6 GM |
2979 | ** Calc |
2980 | ||
2981 | *** Support for musical notes. | |
2982 | ||
2983 | *** Support for logarithmic units. | |
2984 | ||
2985 | *** No longer uses the tex prefix for TeX specific unit names when | |
2986 | using TeX or LaTeX mode. | |
2987 | ||
2988 | *** New option to highlight selections using faces. | |
2989 | ||
2990 | *** `calc-histogram' has the option of using a vector to determine the bins. | |
2991 | ||
2992 | *** New "O" option prefix. | |
2993 | ||
2994 | *** Use the "O" prefix to "d r" (`calc-radix') to turn on twos-complement mode. | |
2995 | ||
cf16af42 GM |
2996 | ** Calendar, Diary, and Appt |
2997 | ||
7d301ae6 | 2998 | *** Diary entries can contain non-printing "comments". |
548d0a63 GM |
2999 | See the variable `diary-comment-start'. |
3000 | ||
5006e634 GM |
3001 | *** Appointments can specify their individual warning times. |
3002 | See the variable `appt-warning-time-regexp'. | |
3003 | ||
0a2bb1a9 GM |
3004 | *** The function specified by `appt-disp-window-function' may be passed |
3005 | lists of arguments if multiple appointments are due at similar times. | |
3006 | If you are using a custom function for this, you should update it. | |
3007 | ||
7454f200 GM |
3008 | *** New function `diary-hebrew-birthday'. |
3009 | ||
e565dd37 GM |
3010 | *** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array' |
3011 | may no longer be nil, but must all be strings. | |
3012 | ||
7d301ae6 CY |
3013 | *** The obsolete (since Emacs 22.1) method of enabling the appt |
3014 | package by adding `appt-make-list' to `diary-hook' has been removed. | |
3015 | Use `appt-activate' instead. | |
cf16af42 | 3016 | |
cf16af42 GM |
3017 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: |
3018 | appt-issue-message (use the function appt-activate) | |
3019 | appt-visible/appt-msg-window (use the variable appt-display-format) | |
3020 | ||
cf16af42 GM |
3021 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: |
3022 | view-diary-entries, list-diary-entries, show-all-diary-entries | |
3023 | ||
551b046f | 3024 | ** CC Mode |
dfdb4cad | 3025 | |
551b046f | 3026 | *** New feature to "guess" the style in an existing buffer. |
7d301ae6 | 3027 | The main entry point is M-x c-guess. |
041d709f | 3028 | |
551b046f AM |
3029 | *** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang). |
3030 | ||
dfdb4cad | 3031 | *** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes. |
551b046f AM |
3032 | Thus C-M-a will, by default, go to the beginning of the immediate function, |
3033 | not the top level. | |
3034 | ||
dfdb4cad | 3035 | *** "Macros with semicolons" can be registered for correct indentation. |
551b046f AM |
3036 | Where such a macro ends a line (no semicolon) the next statement is no longer |
3037 | parsed as a statement continuation. | |
3038 | ||
dfdb4cad | 3039 | ** Comint and modes derived from it use the standard completion code. |
041d709f CY |
3040 | |
3041 | ** Compilation mode | |
dfdb4cad | 3042 | |
7d301ae6 | 3043 | *** Compilation mode can be used without Font Lock mode. |
041d709f CY |
3044 | `compilation-parse-errors-function' is now obsolete. |
3045 | ||
dfdb4cad | 3046 | *** New variable `compilation-filter-start', which is bound while |
7d301ae6 CY |
3047 | `compilation-filter-hook' runs. It records the start position of the |
3048 | text inserted by `compilation-filter'. | |
041d709f | 3049 | |
47a6a35f GM |
3050 | *** `compilation-error-screen-columns' and `compilation-first-column' |
3051 | are obeyed in the editing buffer. So programming language modes can | |
7d301ae6 CY |
3052 | set them, whereas previously only the value in the *Compilation* |
3053 | buffer was used. | |
1dce7193 | 3054 | |
52834b6b CY |
3055 | ** Customize |
3056 | ||
3057 | *** Customize buffers now contain a search field. | |
3058 | The search is performed using `customize-apropos'. | |
7d301ae6 | 3059 | To turn off the search field, set `custom-search-field' to nil. |
52834b6b | 3060 | |
8d5dd370 | 3061 | *** Options in customize group buffers start out hidden if not customized. |
52834b6b CY |
3062 | Use the arrow to the left of the option name to toggle visibility. |
3063 | ||
3064 | *** custom-buffer-sort-alphabetically now defaults to t. | |
3065 | ||
3066 | *** The color widget now has a "Choose" button, which allows you to | |
7d301ae6 | 3067 | choose a color via `list-colors-display'. |
52834b6b | 3068 | |
041d709f CY |
3069 | ** D-Bus |
3070 | ||
5da3be7f GM |
3071 | *** It is now possible to access buses other than the default system |
3072 | or session bus. | |
041d709f | 3073 | |
7d301ae6 | 3074 | *** The `dbus-register-method' and `dbus-register-property' functions |
5da3be7f | 3075 | optionally do not register names. |
041d709f | 3076 | |
7d301ae6 | 3077 | *** The new function `dbus-register-service' registers a known service |
dfdb4cad | 3078 | name on a D-Bus without also registering a property or a method. |
041d709f | 3079 | |
f5d6548a | 3080 | ** Dired-x |
425a25f1 | 3081 | |
7d301ae6 CY |
3082 | *** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'), |
3083 | if called with a prefix argument, read a file name from the minibuffer | |
3084 | instead of using the current buffer. | |
f5d6548a | 3085 | |
7d301ae6 | 3086 | *** The "dired local variables" feature of Dired-x is obsolete. |
817b48a7 | 3087 | The standard directory local variables feature replaces it. |
8117868f | 3088 | |
041d709f | 3089 | ** ERC changes |
7492acc9 | 3090 | |
c4077254 GM |
3091 | *** New options `erc-autojoin-timing' and `erc-autojoin-delay', |
3092 | controlling attempts to autojoin a channel. | |
041d709f CY |
3093 | |
3094 | *** New variable `erc-coding-system-precedence': If we use `undecided' | |
3095 | as the server coding system, this variable will then be consulted. | |
3096 | The default is to decode strings that can be decoded as utf-8 as | |
3097 | utf-8, and do the normal `undecided' decoding for the rest. | |
7492acc9 | 3098 | |
041d709f | 3099 | ** Eshell changes |
7492acc9 | 3100 | |
05f77e38 GM |
3101 | *** The default value of `eshell-directory-name' has changed |
3102 | to be an "eshell" directory in `user-emacs-directory'. | |
3103 | The old "~/.eshell/" directory is still used if it exists, though. | |
041d709f CY |
3104 | |
3105 | ** gdb-mi | |
dfdb4cad CY |
3106 | |
3107 | *** The M-x gdb command now uses the GDB Machine Interface protocol. | |
05f77e38 GM |
3108 | It now supports multithread non-stop debugging and simultaneous |
3109 | debugging of several threads. | |
7492acc9 | 3110 | |
18af70d0 CY |
3111 | ** Image mode |
3112 | ||
05f77e38 GM |
3113 | *** RET (`image-toggle-animation') toggles animation, if applicable. |
3114 | Animation plays once, unless the option `image-animate-loop' is non-nil. | |
18af70d0 | 3115 | |
041d709f | 3116 | ** Info |
723ee192 | 3117 | |
7d301ae6 | 3118 | *** New command M-x info-display-manual displays a named Info manual. |
2ebc3b94 GM |
3119 | If that manual is already visited in some Info buffer, it displays |
3120 | that buffer. (This is handy if you have many manuals in many *info* | |
3121 | buffers, and don't remember the name of the buffer visiting the manual | |
3122 | you want to consult.) Otherwise, it loads and displays the manual. | |
691cf4a0 | 3123 | |
24ea72d3 EZ |
3124 | *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'. |
3125 | This is for compatibility with the stand-alone Info reader program, | |
3126 | and also because `Info-edit' is a rarely used command that is disabled | |
3127 | by default. | |
3128 | ||
7d301ae6 | 3129 | ** Mail mode changes (not Message mode) |
dfdb4cad | 3130 | |
7d301ae6 | 3131 | *** New command M-x mail-add-attachment for adding MIME attachments |
7d301ae6 | 3132 | |
dfdb4cad CY |
3133 | *** The command M-x mail-attach-file was renamed to M-x mail-insert-file. |
3134 | (Its name is misleading, since it has nothing to do with MIME | |
3135 | attachments.) The old name is now an obsolete alias to the new name. | |
3136 | ||
f2c3a9eb | 3137 | ** MH-E has been updated to MH-E version 8.3.1. |
041d709f | 3138 | See MH-E-NEWS for details. |
37221432 | 3139 | |
041d709f | 3140 | ** Modula-2 mode provides auto-indentation. |
37221432 | 3141 | |
041d709f | 3142 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
3c3d4f5b | 3143 | |
5d1ac394 | 3144 | ** nXML mode no longer binds C-RET to `nxml-complete'. |
dfdb4cad CY |
3145 | Completion is now performed via `completion-at-point', bound to C-M-i |
3146 | or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the | |
3147 | default), this performs tag completion. | |
5d1ac394 | 3148 | |
f2c3a9eb CY |

3150 | See ORG-NEWS for details. | |
3151 | ||
041d709f | 3152 | ** Prolog mode has been completely revamped, with lots of additional |
7d301ae6 CY |
3153 | functionality such as more intelligent indentation, electricity, |
3154 | support for more variants, including Mercury, and a lot more. | |
041d709f CY |
3155 | |
3156 | ** Rmail | |

3160 | ||
50419064 GM |
3161 | *** The variable `rmail-message-filter' no longer has any effect. |

3169 | the variable `explicit-shell-file-name' is set. | |
3170 | ||
3171 | *** TAB is now bound to the standard `completion-at-point' command, | |
3172 | which now implements the pcomplete rules for shell command completion. | |

3174 | ** SMTPmail |
3175 | ||
dfdb4cad | 3176 | *** SMTPmail now uses encrypted connections (via STARTTLS) by default |
7d301ae6 CY |
3177 | if the mail server supports them. This uses either built-in GnuTLS |
3178 | support, or the starttls.el library. Customize `smtpmail-stream-type' | |
3179 | to change this. | |
3180 | ||
7d301ae6 CY |
3181 | *** The variable `smtpmail-auth-credentials' has been removed. |
3182 | By default, the information is now stored in the file ~/.authinfo. | |
dfdb4cad CY |
3183 | This was the default value of smtpmail-auth-credentials. If you had |
3184 | customized smtpmail-auth-credentials to a list of user names and | |
3185 | passwords, those settings are not used. During your first connection | |
3186 | to the smtp server, Emacs will prompt for the user name and password, | |
3187 | and offer to save them to ~/.authinfo. Or you can manually copy the | |
3188 | credentials to ~/.authinfo. For example, if you had | |
7d301ae6 CY |
3189 | |
3190 | (setq smtpmail-auth-credentials | |
3191 | '(("mail.example.org" 25 "jim" "s!cret"))) | |
3192 | ||
3193 | then the equivalent line in ~/.authinfo would be | |
3194 | ||
3195 | machine mail.example.org port 25 login jim password s!cret | |
3196 | ||
3197 | See the auth-source manual for more information, e.g. on encrypting | |
3198 | the credentials file. | |
3199 | ||
7d301ae6 | 3200 | *** The variable `smtpmail-starttls-credentials' has been removed. |
dfdb4cad | 3201 | If you had that set, you need to put |
7d301ae6 CY |
3202 | |
3203 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert" | |
3204 | ||
3205 | in your ~/.authinfo file instead. | |
3206 | ||
8ce192e3 LI |
3207 | *** SMTPmail defaults to using the address in the From: header as the |
3208 | SMTP MAIL FROM envelope. To override this, set `mail-envelope-from' | |
3209 | to the address you wish to use instead. | |

34e8a2da | 3211 | ** SQL mode |
041d709f | 3212 | |
34e8a2da GM |
3213 | *** New options `sql-port', `sql-connection-alist', `sql-send-terminator', |
3214 | and `sql-oracle-scan-on'. | |
041d709f | 3215 | |
dfdb4cad | 3216 | *** New options controlling prompting for login parameters. |
34e8a2da GM |
3217 | Each supported product has a custom variable `sql-*-login-params', |
3218 | which is a list of the parameters to be prompted for before a | |
3219 | connection is established. | |
041d709f CY |
3220 | |
3221 | *** The command `sql-product-interactive' now takes a prefix argument, | |
34e8a2da | 3222 | which causes it to prompt for an SQL product. |
041d709f | 3223 | |
34e8a2da | 3224 | *** Product-specific SQL interactive commands now take prefix arguments. |
041d709f CY |
3225 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), |
3226 | given a prefix argument, prompt for a name for the SQL interactive | |
3227 | buffer. This reduces the need for calling `sql-rename-buffer'. | |
3228 | ||
3229 | *** SQL interactive modes suppress command continuation prompts, and | |
3230 | replace tabs with spaces. The first change impacts multiple line SQL | |
3231 | statements entered with C-j between each line, statements yanked into | |
3232 | the buffer and statements sent with `sql-send-*' functions. The | |
34e8a2da GM |
3233 | second prevents the MySQL and Postgres interpreters from listing |
3234 | object name completions when sent text via `sql-send-*' functions. | |
041d709f CY |
3235 | |
3236 | *** New command `sql-connect' starts a predefined SQLi session, | |
3237 | using the login parameters from `sql-connection-alist'. | |
3238 | ||
3239 | *** New "Save Connection" menu item in SQLi buffers. | |
3240 | This gathers the login params specified for the SQLi session, if it | |
3241 | was not started by a connection, and saves them as a new connection. | |
3242 | ||
34e8a2da GM |
3243 | *** New commands for listing database objects and details: |
3244 | sql-list-all and sql-list-table. | |
041d709f CY |
3245 | |
3246 | *** An API for manipulating SQL product definitions has been added. | |
3247 | ||
3248 | ** TeX modes | |
3249 | ||
3250 | *** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. | |

dfdb4cad | 3253 | |
7d301ae6 | 3254 | *** New inline access method "ksu" (kerberized su). |
dfdb4cad | 3255 | |
459bba37 | 3256 | *** The following access methods are discontinued: "ssh1_old", |
ea843702 | 3257 | "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish". |
dfdb4cad | 3258 | |
b011fbfe GM |
3259 | *** The user option `remote-file-name-inhibit-cache' controls whether |
3260 | remote file attributes are cached for better performance. | |
dfdb4cad | 3261 | |
58f74fe4 MA |
3262 | *** The option `ange-ftp-binary-file-name-regexp' has changed its |
3263 | default value to "". | |
dfdb4cad | 3264 | |
7d301ae6 CY |
3265 | *** Handlers for `file-selinux-context' and `set-file-selinux-context' |
3266 | for remote machines which support SELinux. | |
58f74fe4 | 3267 | |
dfdb4cad | 3268 | ** New function `url-queue-retrieve', which behaves like url-retrieve, |
a48ec60c GM |
3269 | but with limits (`url-queue-parallel-processes', `url-queue-timeout') on |
3270 | the degree of parallelism. | |

3272 | ** VC and related modes |
3273 | ||
3274 | *** Support for pulling on distributed version control systems. | |
7d301ae6 CY |
3275 | The command C-x v + (`vc-pull') runs a "pull" operation, if it is |
3276 | supported (currently with Bzr, Git, and Mercurial), to update the | |
3277 | current branch and working tree. A prefix argument means to prompt | |
3278 | the user for specifics, e.g. a pull location. | |
0c32ce32 | 3279 | |
dab3703d | 3280 | *** `vc-update' is now an alias for `vc-pull'. |
0c32ce32 CY |
3281 | |
3282 | *** Support for merging on distributed version control systems. | |
7d301ae6 CY |
3283 | The command C-x v m (`vc-merge') now runs a "merge" operation, if it |
3284 | is supported (currently with Bzr, Git, and Mercurial), to merge | |
3285 | changes from another branch into the current one. It prompts for | |
3286 | specifics, e.g. a merge source. | |
0c32ce32 | 3287 | |
2afef60a | 3288 | *** New option `vc-revert-show-diff' controls whether `vc-revert' |
bbe43420 | 3289 | shows a diff while querying the user. It defaults to t. |
2afef60a | 3290 | |
d4eb88c7 CY |
3291 | *** Log entries in some Log View buffers can be toggled to display a |
3292 | longer description by typing RET (log-view-toggle-entry-display). | |
dab3703d GM |
3293 | This is currently supported for Bzr, Git, and Mercurial (to support |
3294 | another backend, define a `log-view-expanded-log-entry-function'). | |
7d301ae6 | 3295 | In the Log View buffers made by C-x v L (`vc-print-root-log'), you can |
d4eb88c7 CY |
3296 | use this to display the full log entry for the revision at point. |
3297 | ||
1c6c854e CS |
3298 | *** New command `vc-ediff' allows visual comparison of two revisions |
3299 | of a file similar to `vc-diff', but using ediff backend. | |
3300 | ||
86c60681 CY |
3301 | *** The option `vc-initial-comment' was removed in Emacs 23.2, but |
3302 | this was not advertised at the time. | |
3303 | ||
86c60681 CY |
3304 | *** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'. |
3305 | Since Emacs 23, it has done the same thing as `toggle-read-only', but | |
80c6d77f GM |
3306 | this was not advertised at the time. |

f8ca9162 | 3312 | *** erc-hecomplete.el (use erc-pcomplete.el instead) |
23d70505 GM |
3313 | |
3314 | *** partial-completion-mode (complete.el) is obsolete. | |
041d709f CY |
3315 | You can get a comparable behavior with: |
3316 | (setq completion-styles '(partial-completion initials)) | |
3317 | (setq completion-pcm-complete-word-inserts-delimiters t) | |
3318 | ||
23d70505 GM |
3319 | *** pc-mode.el is obsolete (CUA mode is much more comprehensive). |
3320 | ||
2c719188 | 3321 | *** pgg is obsolete (use EasyPG instead). |
041d709f CY |
3322 | |
3323 | *** sregex.el is obsolete, since rx.el is a strict superset. | |
3324 | ||
23d70505 GM |
3325 | *** s-region.el and pc-select.el are obsolete. |
3326 | They are superseded by shift-select-mode, enabled by default since 23.1. | |
3327 | ||
2c719188 | 3328 | *** vc-mcvs.el is obsolete (for lack of a maintainer). |

3330 | ** Miscellaneous |
3331 | ||
05f77e38 | 3332 | *** The Landmark game is now invoked with `landmark', not `lm'. |
c6ad2a4e | 3333 | Its functions and variables have been similarly renamed. |
05f77e38 | 3334 | |
dfdb4cad | 3335 | *** In `ido-file-completion-map', C-v is no longer bound to `ido-toggle-vc'. |
05f77e38 GM |
3336 | (This interfered with cua-mode.) |
3337 | ||
9f678528 GM |
3338 | *** f90.el has some support for Fortran 2008 syntax. |

3345 | * New Modes and Packages in Emacs 24.1 | |
d445b3f8 | 3346 | |
60e56523 | 3347 | ** Occur Edit mode applies edits made in *Occur* buffers to the |
8c0f49f0 | 3348 | original buffers. It is bound to "e" in Occur mode. |
60e56523 | 3349 | |
a075a2c5 GM |
3350 | ** New global minor mode electric-pair-mode. |
3351 | When enabled, typing an open parenthesis automatically inserts the | |
3352 | matching closing one. | |
3353 | ||
3354 | ** New global minor mode electric-indent-mode. | |
3355 | When enabled, typing certain characters triggers reindentation. | |
cd3308f3 GM |
3356 | Major modes wishing to use this can set electric-indent-chars or |
3357 | electric-indent-functions. | |
a075a2c5 GM |
3358 | |
3359 | ** New global minor mode electric-layout-mode. | |
3360 | When enabled, typing certain characters automatically inserts newlines. | |
cd3308f3 | 3361 | Major modes wishing to use this can set electric-layout-rules. |
3b843809 | 3362 | |
a83ec3c9 CY |
3363 | ** tabulated-list.el provides a generic major mode for tabulated data, |
3364 | from which other modes can be derived. | |
3365 | ||
d02c9bcd SM |
3366 | ** pcase.el provides the ML-style pattern matching macro `pcase'. |
3367 | ||
7725ebb7 MA |
3368 | ** secrets.el is an implementation of the Secret Service API, an |
3369 | interface to password managers like GNOME Keyring or KDE Wallet. The | |
065f2743 MA |
3370 | Secret Service API requires D-Bus for communication. The command |
3371 | `secrets-show-secrets' offers a buffer with a visualization of the | |
3372 | secrets. | |
7725ebb7 | 3373 | |
f9e78150 MA |
3374 | ** notifications.el provides an implementation of the Desktop |
3375 | Notifications API. It requires D-Bus for communication. | |
3376 | ||
12fe5bcc MA |
3377 | ** soap-client.el supports access to SOAP web services from Emacs. |
3378 | soap-inspect.el is an interactive inspector for SOAP WSDL structures. | |
3379 | ||
ff1796f3 | 3380 | ** New generic mode, xmodmap-generic-mode, for xmodmap files. |
ad7d6ecb | 3381 | |
53bbe3ad | 3382 | ** New emacs-lock.el package. |
7d301ae6 CY |
3383 | The previous version has been moved to obsolete/old-emacs-lock.el. |
3384 | Now, there is a proper minor mode `emacs-lock-mode'. Protection | |
3385 | against exiting Emacs and killing the buffer can be set separately. | |
3386 | The mechanism for automatically turning off protection for buffers | |
3387 | with dead inferior processes has been generalized. | |

3390 | * Incompatible Lisp Changes in Emacs 24.1 | |
6dfcbe31 | 3391 | |
7d301ae6 CY |
3392 | ** Passing a nil argument to a minor mode function call now ENABLES |
3393 | the minor mode unconditionally. This is so that you can write e.g. | |
3394 | ||
dfdb4cad | 3395 | (add-hook 'text-mode-hook 'foo-mode) |
7d301ae6 | 3396 | |
dfdb4cad CY |
3397 | to enable foo-mode in Text mode buffers, removing the need for |
3398 | `turn-on-foo-mode' style functions. This affects all mode commands | |
3399 | defined by `define-minor-mode'. If called interactively, the mode | |
3400 | command still toggles the minor mode. | |
7d301ae6 | 3401 | |
d268b4fe CY |
3402 | ** The return value of `backup-buffer' has changed. |
3403 | It is now a list of three elements, where the second element is a list | |
3404 | describing the original file's SELinux context. If Emacs or the | |
f003f294 | 3405 | system lacks SELinux support, the context list is (nil nil nil nil). |
7d301ae6 | 3406 | See "Basic SELinux support" above, under "Changes in Emacs 24.1". |
d268b4fe | 3407 | |
dfdb4cad CY |
3408 | ** `char-direction-table' and the `char-direction' function were deleted. |
3409 | They were buggy and inferior to the new support of bidirectional | |
3410 | editing introduced in Emacs 24. If you need the bidirectional | |
3411 | properties of a character, use `get-char-code-property' with the last | |
3412 | argument `bidi-class'. | |
fa6996bc | 3413 | |
470d996d TV |
3414 | ** `copy-directory' now copies the source directory as a subdirectory |
3415 | of the target directory, if the latter is an existing directory. The | |
3416 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy | |
3417 | the contents directly into a pre-existing target directory. | |
3418 | ||
9173a8fb CY |
3419 | ** For mouse click input events in the text area, the Y pixel |
3420 | coordinate in the POSITION list now counts from the top of the text | |
3421 | area, excluding any header line. Previously, it counted from the top | |
3422 | of the header line. | |
3423 | ||
7d301ae6 CY |
3424 | ** Support for "old-style" backquotes, obsolete for 10+ years, has |
3425 | been further reduced. Now a backquote not followed by a space is | |
3426 | always treated as a "new-style" backquote. Please remove all | |
3427 | "old-style" backquotes from your code. If your code uses backquotes | |
3428 | as documented in the Elisp manual, and compiles without warning, then | |
3429 | you have nothing to do in this regard. Code not following the | |
3430 | appropriate conventions may fail to compile. | |
50ab02c5 CY |
3431 | |
3432 | The most common cause of trouble seems to be an old-style backquote | |
3433 | followed by a newline. Another cause of trouble is vector notation | |
3434 | for key sequence notation: instead of [(control ,)] and [(control ')], | |
3435 | you should write [(control ?,)] and [(control ?')], which will work in | |
7d301ae6 | 3436 | older Emacsen too. |

520f2425 GM |
3438 | ** The macro `eval-at-startup' was removed in Emacs 23.2, but this |
3439 | was not advertised at the time. The function `custom-initialize-delay' | |
3440 | replaced all known uses. | |
3441 | ||
7d301ae6 CY |
3442 | ** `view-buffer' now treats special mode-class in the same way that |
3443 | `view-file' has since Emacs 22 (i.e. it won't enable View mode if the | |
3444 | major mode is special). | |
fd5c9dfa | 3445 | |
7d301ae6 | 3446 | ** Menu and tool bar changes |

7d301ae6 | 3448 | *** During startup, Emacs no longer adds entries for `menu-bar-lines' |
0a19a6f8 JB |
3449 | and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'. |
3450 | With these alist entries omitted, `make-frame' checks the value of the | |
3451 | variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create | |
3452 | a menu-bar or tool-bar, respectively. If the alist entries are added, | |
3453 | they override the value of `menu-bar-mode'/`tool-bar-mode'. | |
6431f2e6 | 3454 | |
7d301ae6 CY |
3455 | *** The menu bar bindings's caches are not used any more. |
3456 | Use (where-is-internal <def> nil t) instead. | |
3457 | ||
fe0aa820 | 3458 | ** Regions created by mouse dragging are now normal active regions, |
dfdb4cad | 3459 | similar to those created by shift-selection (see Selection changes |
7d301ae6 CY |
3460 | above). In previous Emacs versions, these regions were delineated by |
3461 | `mouse-drag-overlay'; that variable has been removed. | |
d6d8ee7a | 3462 | |
7d301ae6 CY |
3463 | ** The fourth argument of `filter-buffer-substring' has been removed. |
3464 | If you want to remove text properties from the final result, simply | |

3507 | ** The format of the finder-inf.el file has changed, since the Finder |
3508 | mechanism is now based on the package system. The variable | |
3509 | `finder-package-info' is replaced by `package--builtins' and | |
3510 | `finder-keywords-hash'. | |

3512 | ** When generating autoloads, `update-directory-autoloads' no longer |
3513 | assumes every inspected file is in your `load-path'. It instead | |
3514 | generates relative names according to the current `load-path'. | |

93e0bed6 | 3517 | * Lisp Changes in Emacs 24.1 |
9097e8af | 3518 | |
041d709f | 3519 | ** Code can now use lexical scoping by default instead of dynamic scoping. |
dfdb4cad | 3520 | The `lexical-binding' variable enables lexical scoping for local |
48da7392 | 3521 | variables. It is typically set via a file-local variable in the first |
dfdb4cad CY |
3522 | line of the file, in which case it applies to all the code in that |
3523 | file. | |
3524 | ||
041d709f CY |
3525 | *** `eval' takes a new optional argument `lexical' to choose the new lexical |
3526 | binding instead of the old dynamic binding mode. | |
dfdb4cad | 3527 | |
041d709f CY |
3528 | *** Lexically scoped interpreted functions are represented with a new form |
3529 | of function value which looks like (closure ENV ARGS &rest BODY). | |
3530 | ||
3531 | *** New macro `letrec' to define recursive local functions. | |
dfdb4cad CY |
3532 | |
3533 | *** `defvar' and `defconst' now mark the variable as special (dynamic). | |
3534 | So do `defcustom' and other forms that call `defvar' as a subroutine. | |
3535 | ||
041d709f CY |
3536 | *** New function `special-variable-p' to check whether a variable is |
3537 | declared as dynamically bound. | |
3538 | ||
88ed9e87 SM |
3539 | *** The form ((lambda ...) ...) is deprecated. |
3540 | ||
041d709f CY |
3541 | ** An Emacs Lisp testing tool is now included. |
3542 | Emacs Lisp developers can use this tool to write automated tests for | |
3543 | their code. See the ERT info manual for details. | |
3544 | ||
3545 | ** Changes for bidirectional display and editing | |
f1816485 | 3546 | |
041d709f | 3547 | *** New function `current-bidi-paragraph-direction'. |
7d301ae6 | 3548 | This returns the base direction of the paragraph at point. |
041d709f | 3549 | |
041d709f | 3550 | *** New function `bidi-string-mark-left-to-right'. |
dfdb4cad CY |
3551 | Given a string containing characters from right-to-left scripts, this |
3552 | function returns another string which can be safely inserted into a | |
3553 | buffer, such that any following text will be always displayed to the | |
7d301ae6 CY |
3554 | right of that string. (This works by appending an invisible Unicode |
3555 | "LEFT-TO-RIGHT MARK" character if the argument string might need it.) | |
041d709f | 3556 | |
7d301ae6 | 3557 | This is useful when the buffer has overall left-to-right paragraph |
dfdb4cad CY |
3558 | direction and you need to insert a string whose contents are not known |
3559 | in advance, without disrupting the layout of the line. | |
041d709f | 3560 | |
bee0fcef | 3561 | ** Window changes |
dfdb4cad | 3562 | |
c4682d18 MR |
3563 | *** Window tree functions are accessible in Elisp. |
3564 | Functions are provided to return the parent, siblings or child windows | |
3565 | of any window including internal windows (windows not associated with a | |
3566 | buffer) in the window tree. | |
dfdb4cad | 3567 | |
24300f5f CY |
3568 | **** New function `window-valid-p' gives non-nil for live and internal |
3569 | windows. | |
dfdb4cad | 3570 | |
24300f5f | 3571 | **** Window manipulation can deal with internal windows. |
c4682d18 MR |
3572 | Many window handling functions like `split-window', `delete-window', or |
3573 | `delete-other-windows' as well as the window resizing functions can now | |
3574 | act on any window including internal ones. | |
dfdb4cad | 3575 | |
c4682d18 MR |
3576 | *** window-total-height/-width vs window-body-height/-width. |
3577 | The function `window-height' has been renamed to `window-total-height' | |
3578 | and `window-width' has been renamed to `window-body-width'. The old | |
3579 | names are provided as aliases. Two new functions `window-total-width' | |
3580 | and `window-body-height' are provided. | |
dfdb4cad | 3581 | |
c4682d18 MR |
3582 | *** Window parameters specific to window handling functions. |
3583 | For each window you can specify a parameter to override the default | |
3584 | behavior of a number of functions like `split-window', `delete-window' | |
ed6235ea MR |
3585 | and `delete-other-windows'. The variable `ignore-window-parameters' |
3586 | allows to ignore processing such parameters. | |
dfdb4cad | 3587 | |
c4682d18 | 3588 | *** New semantics of third argument of `split-window'. |
c4682d18 MR |
3589 | The third argument of `split-window' has been renamed to SIDE and can be |
3590 | set to any of the values 'below, 'right, 'above, or 'left to make the | |
3591 | new window appear on the corresponding side of the window that shall be | |
3592 | split. Any other value of SIDE will cause `split-window' to split the | |
3593 | window into two side-by-side windows as before. | |
dfdb4cad | 3594 | |
c4682d18 | 3595 | *** Window resizing functions. |
487ffd7a | 3596 | A new standard function for resizing windows called `window-resize' has |
c4682d18 MR |
3597 | been introduced. This and all other functions for resizing windows no |
3598 | longer delete any windows when they become too small. | |
dfdb4cad | 3599 | |
b3c0dbfd MR |
3600 | *** Deleting the selected window now selects the most recently selected |
3601 | live window on that frame instead. | |
dfdb4cad | 3602 | |
c4682d18 MR |
3603 | *** `adjust-window-trailing-edge' adjustments. |
3604 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | |
3605 | is able to resize other windows if a window adjacent to the trailing | |
3606 | edge cannot be shrunk any more. This makes its behavior more similar to | |
3607 | that of Emacs 21 without compromising, however, its inability to delete | |
3608 | windows which was introduced in Emacs 22. | |
dfdb4cad | 3609 | |
c4682d18 MR |
3610 | *** Window-local buffer lists. |
3611 | Windows now have local buffer lists. This means that removing a buffer | |
3612 | from display in a window will preferably show the buffer previously | |
3613 | shown in that window with its previous window-start and window-point | |
3614 | positions. This also means that the same buffer may be automatically | |
3615 | shown twice even if it already appears in another window. | |
dfdb4cad | 3616 | |
bee0fcef CY |
3617 | *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW, |
3618 | which if non-nil requires the buffer to be displayed in the currently | |
3619 | selected window, signaling an error otherwise. If nil, another window | |
3620 | can be used, e.g. if the selected one is strongly dedicated. | |
dfdb4cad | 3621 | |
0a2132ba | 3622 | *** `split-window-vertically' and `split-window-horizontally' renamed |
2d197ffb CY |
3623 | to `split-window-below' and `split-window-right' respectively. |
3624 | The old names are kept as aliases. | |
dfdb4cad | 3625 | |
0a2132ba CY |
3626 | *** Display actions |
3627 | ||
3628 | **** The second arg to `display-buffer' and `pop-to-buffer' is now | |
3629 | named ACTION, and takes a display action of the same form as | |
3630 | `display-buffer-base-action' (see Changes, above). A non-nil, | |
3631 | non-list value is treated specially, as the old meaning. | |
3632 | ||
3633 | **** New variable `display-buffer-overriding-action'. | |
3634 | ||
3635 | **** The procedure of `display-buffer' etc. to choose a window is | |
3636 | determined by combining `display-buffer-overriding-action', | |
3637 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', | |
3638 | and `display-buffer-fallback-action'. The second and fourth of these | |
3639 | are user-customizable variables. | |
3640 | ||
3641 | See the docstring of `display-buffer' for details. | |
bee0fcef | 3642 | |
20d2304d CY |
3643 | *** New functions `window-state-get' and `window-state-put'. |
3644 | These functions allow to save and restore the state of an arbitrary | |
3645 | frame or window as an Elisp object. | |
3646 | ||
a2a25d24 | 3647 | ** Completion |
041d709f | 3648 | |
7d301ae6 CY |
3649 | *** New variable `completion-extra-properties' used to specify extra |
3650 | properties of the current completion: | |
a2a25d24 SM |
3651 | - :annotate-function, same as the old completion-annotate-function. |
3652 | - :exit-function, function to call after completion took place. | |
3653 | ||
7d301ae6 CY |
3654 | *** Functions on `completion-at-point-functions' can return any of the |
3655 | properties valid for `completion-extra-properties'. | |
a2a25d24 | 3656 | |
7d301ae6 | 3657 | *** `completion-annotate-function' is obsolete. |
a2a25d24 | 3658 | |
620c53a6 SM |
3659 | *** New `metadata' method for completion tables. The metadata thus returned |
3660 | can specify various details of the data returned by `all-completions': | |
3661 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | |
3662 | used to select a style in completion-category-overrides. | |
3663 | - `annotation-function' to add annotations in *Completions*. | |
3664 | - `display-sort-function' to specify how to sort entries in *Completions*. | |
3665 | - `cycle-sort-function' to specify how to sort entries when cycling. | |
3666 | ||
7d301ae6 CY |
3667 | *** `minibuffer-local-filename-must-match-map' is not used any more. |
3668 | Instead, the bindings in `minibuffer-local-filename-completion-map' | |
3669 | are combined with `minibuffer-local-must-match-map'. | |
de09aa52 CY |
3670 | |
3671 | *** New variable `completing-read-function' allows overriding the | |
3672 | behavior of `completing-read'. | |
3673 | ||
f042970d | 3674 | ** `glyphless-char-display' can now distinguish between graphical and |
16a43933 CY |
3675 | text terminal display, via a char-table entry that is a cons cell. |
3676 | ||
7d301ae6 | 3677 | ** `pre-command-hook'/`post-command-hook' are not reset to nil on error. |
f6d62986 SM |
3678 | Instead, the offending function is removed. |
3679 | ||
b1f6fa26 CY |
3680 | ** New hook types |
3681 | ||
3682 | *** New function `run-hook-wrapped' for running an abnormal hook by | |
3683 | passing the hook functions as arguments to a "wrapping" function. | |
e7bc51d0 | 3684 | Like `run-hook-with-args-until-success', it stops at the first |
5385447f | 3685 | non-nil return value. |
e7bc51d0 | 3686 | |
b1f6fa26 CY |
3687 | *** New macro `with-wrapper-hook' for running an abnormal hook as a |
3688 | set of "wrapping" filters, similar to around advice. | |
54521c99 GM |
3689 | (A version of this macro was actually added in Emacs 23.2 but was not |
3690 | advertised at the time.) | |
f6d62986 | 3691 | |
0b19b281 | 3692 | ** Debugger changes |
dfdb4cad | 3693 | |
0b19b281 | 3694 | *** New macro `condition-case-unless-debug' (this was actually added in |
1be3ca5a | 3695 | Emacs 23.1 as condition-case-no-debug, but not advertised) |
dfdb4cad | 3696 | |
0b19b281 | 3697 | *** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised. |
dfdb4cad | 3698 | |
0b19b281 | 3699 | *** Variable `stack-trace-on-error' removed. |
dfdb4cad | 3700 | |
0b19b281 CY |
3701 | *** The debugger can now "continue" from an error, which means it will |
3702 | jump to the error handler as if the debugger had not been invoked | |
3703 | instead of jumping all the way to the top-level. | |
dfdb4cad | 3704 | |
0b19b281 CY |
3705 | *** Set `debug-on-event' to enter the debugger on events like SIGUSR1. |
3706 | This can be useful when `inhibit-quit' is set. | |
d6b1d521 | 3707 | |
953cebf5 | 3708 | ** The new function `server-eval-at' allows evaluation of Lisp forms on |
37576acd | 3709 | named Emacs server instances. |
7deebf1b | 3710 | |
1b9f60cc GM |
3711 | ** `call-process' and `call-process-region' allow a `(:file "file")' spec |
3712 | to redirect STDOUT to a file. | |
7deebf1b | 3713 | |
7d301ae6 CY |
3714 | ** The function `format-time-string' now supports the %N directive, |
3715 | for higher-resolution time stamps. | |
da97a9e6 | 3716 | |
0b19b281 | 3717 | ** New input reading functions |
dfdb4cad | 3718 | |
0b19b281 CY |
3719 | *** New function `read-char-choice' reads a restricted set of |
3720 | characters, discarding any inputs not inside the set. | |
dfdb4cad | 3721 | |
0b19b281 CY |
3722 | *** The command `read-color' now requires a match for a color name |
3723 | or RGB triplet, instead of signaling an error if the user provides | |
3724 | invalid input. | |
dfdb4cad | 3725 | |
0b19b281 | 3726 | **** `facemenu-read-color' is now an alias for `read-color'. |
3ef01959 | 3727 | |
2e288d54 JB |
3728 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
3729 | The variable is now used to load all kind of supported dynamic libraries, | |
3730 | not just image libraries. The previous name is still available as an | |
3731 | obsolete alias. | |
3732 | ||
0b19b281 | 3733 | ** Syntax parsing changes |
dfdb4cad | 3734 | |
0b19b281 | 3735 | *** New variable `syntax-propertize-function'. |
04e2ce72 | 3736 | This replaces `font-lock-syntactic-keywords' which is now obsolete. |
cf38dd42 SM |
3737 | This allows syntax-table properties to be set independently from font-lock: |
3738 | just call syntax-propertize to make sure the text is propertized. | |
3739 | Together with this new variable come a new hook | |
3740 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
3741 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
3742 | as-is; and syntax-propertize-rules which provides a new way to specify | |
3743 | syntactic rules. | |
dfdb4cad | 3744 | |
0b19b281 | 3745 | *** Syntax tables support a new "comment style c" additionally to style b. |
a2e5caf7 | 3746 | |
7d301ae6 | 3747 | ** New hook `post-self-insert-hook', run after `self-insert-command'. |
041d709f | 3748 | |
4e2db1fe | 3749 | ** frame-local variables cannot be let-bound any more. |
041d709f | 3750 | |
15de15c6 | 3751 | ** Major and minor mode changes |
dfdb4cad | 3752 | |
0b19b281 CY |
3753 | *** `set-auto-mode' now respects mode: local variables at the end of files, |
3754 | as well as those in the -*- line. | |
dfdb4cad | 3755 | |
15de15c6 CY |
3756 | *** `prog-mode' is a new major mode from which programming modes |
3757 | should be derived. | |
dfdb4cad | 3758 | |
15de15c6 CY |
3759 | **** `prog-mode-hook' can be used to enable features for programming |
3760 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable | |
3761 | on-the-fly spell checking for comments and strings. | |
dfdb4cad | 3762 | |
15de15c6 CY |
3763 | *** New hook `change-major-mode-after-body-hook', run by |
3764 | `run-mode-hooks' just before any other mode hooks. | |
dfdb4cad | 3765 | |
7a9a2fc6 GM |
3766 | *** Enabled globalized minor modes can be disabled in specific major modes. |
3767 | If the global mode is global-FOO-mode, then run (FOO-mode -1) in the | |
3768 | major mode's hook, where FOO-mode toggles the mode on a per-buffer basis. | |
dfdb4cad | 3769 | |
feb8a83a | 3770 | *** `define-minor-mode' accepts new keywords :variable, :after-hook. |
f44379e7 | 3771 | |
7d301ae6 CY |
3772 | ** File-handling changes |
3773 | ||
7d301ae6 | 3774 | *** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
3775 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
3776 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
3777 | argument is supplied (see Trash changes, above). | |
53967e09 | 3778 | |
7d301ae6 | 3779 | *** New file predicates: `file-equal-p', `file-in-directory-p'. |
ec70a47d | 3780 | |
4039c786 CY |
3781 | ** Tool-bars can display separators. |
3782 | Tool-bar separators are handled like menu separators in menu-bar maps, | |
94975270 | 3783 | i.e. via menu entries of the form `(menu-item "--")'. |
9317e499 | 3784 | |
00fe2df1 JL |
3785 | ** Image API |
3786 | ||
18af70d0 CY |
3787 | *** Animated images support (currently animated gifs only). |
3788 | ||
3789 | **** `image-animated-p' returns non-nil if an image can be animated. | |
3790 | ||
3791 | **** `image-animate' animates a supplied image spec. | |
3792 | ||
3793 | **** `image-animate-timer' returns the timer object for an image that | |
3794 | is being animated. | |
00fe2df1 | 3795 | |
7cb76fe0 GM |
3796 | *** `image-extension-data' has been renamed to `image-metadata'. |
3797 | The old name is an obsolete alias to the new one. | |
1546c559 | 3798 | |
b4ac6e8c GM |
3799 | *** Image mode can view any image type that ImageMagick supports. |
3800 | This requires Emacs to be built with ImageMagick support. | |
7d301ae6 CY |
3801 | |
3802 | **** New function `imagemagick-types', defined if ImageMagick support | |
3803 | is enabled, returns a list of image file extensions that your | |
3804 | ImageMagick installation supports. | |
3805 | ||
3806 | **** New function `imagemagick-register-types' enables ImageMagick | |
3807 | image types in Image mode and in `create-image' and other helper | |
3808 | functions. | |
3809 | ||
3810 | **** New option `imagemagick-types-inhibit' excludes certain | |
3811 | ImageMagick image types from `imagemagick-register-types'. | |
3812 | ||
7d301ae6 CY |
3813 | **** With ImageMagick support, there are extra Image mode commands to |
3814 | resize and rotate images: `image-transform-fit-to-height', | |
3815 | `image-transform-fit-to-width', `image-transform-set-rotation', and | |
3816 | `image-transform-set-scale'. | |
041d709f | 3817 | |
7d301ae6 CY |
3818 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
3819 | passes it to the mail user agent function. This argument specifies an | |
3820 | action for returning to the caller after finishing with the mail. For | |
3821 | example, this is used by Rmail to optionally delete a mail window. | |
b4ac6e8c | 3822 | |
71c17aec | 3823 | ** XML and HTML parsing |
483ab230 CY |
3824 | If Emacs is compiled with libxml2 support, there are two new |
3825 | functions: `libxml-parse-html-region' (which parses "real world" HTML) | |
3826 | and `libxml-parse-xml-region' (which parses XML). Both return an | |
3827 | Emacs Lisp parse tree. | |
4b9832a6 | 3828 | |
7d301ae6 | 3829 | ** Networking and encryption changes |
e2574f2c | 3830 | |
7d301ae6 CY |
3831 | *** `open-network-stream' can now be used to open an encrypted stream. |
3832 | It now accepts an optional `:type' parameter for initiating a TLS | |
3833 | connection, directly or via STARTTLS. To do STARTTLS, additional | |
3834 | parameters (`:end-of-command', `:success', `:capabilities-command') | |
3835 | must also be supplied. | |
3836 | ||
3837 | *** New library gnutls.el. | |
dfdb4cad CY |
3838 | The new function `gnutls-available-p' returns non-nil if Emacs is |
3839 | built with GnuTLS support. The main entry points are | |
3840 | `open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use | |
3841 | these functions through `open-network-stream', because that can | |
7d301ae6 CY |
3842 | upgrade connections through STARTTLS opportunistically or use plain |
3843 | SSL, depending on your needs. For debugging, set `gnutls-log-level' | |
3844 | greater than 0. | |
3845 | ||
7d301ae6 CY |
3846 | *** New primitive `secure-hash' that supports many secure hash algorithms: |
3847 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library | |
3848 | sha1.el has been removed. The `sha1' feature is provided by default. | |

3852 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | |
3853 | ||
9326ba26 CY |
3854 | ** Progress reporters can now "spin". |
3855 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
3856 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
3857 | time you call `progress-reporter-update' on that progress reporter, | |
3858 | with a nil or omitted VALUE argument, the reporter message is | |
3859 | displayed with a "spinning bar". | |
3860 | ||
3e214b50 JB |
3861 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is |
3862 | being reverted, even if the buffer has a local `revert-buffer-function'. | |
3863 | ||
001bf877 GM |
3864 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. |
3865 | If delayed-warnings-list is non-nil, the command loop calls | |
7d301ae6 CY |
3866 | `delayed-warnings-hook' after `post-command-hook'. At present, this |
3867 | is only used by Emacs on some platforms to display warnings during | |
3868 | startup, which might otherwise not be noticed. This uses the | |
3869 | functions `display-delayed-warnings' and `collapse-delayed-warnings'. | |
001bf877 | 3870 | |
6420d28b CY |
3871 | ** rx.el has a new `group-n' construct for explicitly numbered groups. |
3872 | ||
dac86404 GM |
3873 | ** New function `make-composed-keymap' that constructs a new keymap |
3874 | from multiple input maps. You can use this to make a keymap that | |
3875 | inherits from multiple maps, eg: | |
3876 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) | |
43dc9f5b | 3877 | |
c8f6ec5c GM |
3878 | ** New function `string-prefix-p'. |
3879 | (This was actually added in Emacs 23.2 but was not advertised at the time.) | |
3880 | ||
27f7ef2f | 3881 | ** New reader macro ## that stands for the empty symbol. |
43dc9f5b AS |
3882 | This means that the empty symbol can now be read back. Also, #: by itself |
3883 | (when not immediately followed by a possible symbol character) stands for | |
3884 | an empty uninterned symbol. | |
041d709f | 3885 | |
fead402d CY |
3886 | ** New math functions `isnan', `copysign', `frexp', `ldexp'. |
3887 | ||
7d301ae6 | 3888 | ** The following functions and variables are obsolete: |
041d709f | 3889 | |
05f77e38 GM |
3890 | *** `tooltip-use-echo-area' is obsolete. |
3891 | Rather than setting this to t, disable Tooltip mode instead. | |
3892 | ||
041d709f CY |
3893 | *** buffer-substring-filters is obsolete. |
3894 | Use `filter-buffer-substring-functions' instead. | |
3895 | ||
3896 | *** `byte-compile-disable-print-circle' is obsolete. | |
3897 | ||
3898 | *** `deferred-action-list' and `deferred-action-function' are obsolete. | |
f160676e GM |
3899 | Use `post-command-hook' instead. |
3900 | ||
67e729a5 CY |
3901 | *** `font-lock-maximum-size' is obsolete. |

93e0bed6 | 3904 | * Changes in Emacs 24.1 on Non-Free Operating Systems |
d53a60a6 | 3905 | |
7a22e700 | 3906 | ** On MS Windows, Emacs warns when using the obsolete init file _emacs, |
a2f0118c GM |
3907 | and also when HOME is set to C:\ by default. |
3908 | ||
7a22e700 | 3909 | ** New configure.bat options |
04779484 | 3910 | |
7a22e700 | 3911 | *** --enable-checking builds Emacs with extra runtime checks. |
e3aef5c6 | 3912 | |
7a22e700 | 3913 | *** --distfiles specifies files to be included in binary distribution. |
e2574f2c | 3914 | |
7a22e700 OK |
3915 | *** --without-gnutls disables automatic GnuTLS detection. |
3916 | ||
a0d363f4 | 3917 | *** --lib for general library linkage, works with the USER_LIBS build variable. |
e2574f2c | 3918 | |
0a19a6f8 | 3919 | ** New make target `dist' to create binary distribution for MS Windows. |
e3aef5c6 | 3920 | |
1f5e1a16 GM |
3921 | ** The Lisp function `w32-default-color-map' is now obsolete. |
3922 | (It is only used internally in the Emacs C code.) | |
5430d399 | 3923 | |
1f5e1a16 GM |
3924 | ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but |
3925 | reappear on mouse-over. (Requires OS X 10.6 or later.) | |
04e2ce72 | 3926 | |
ad7c802c CY |
3927 | ** On Mac OS X, dragging a file into Emacs visits the file, like on |
3928 | other platforms, rather than inserting its contents into the buffer. | |
