95a32efb | 25 | * Installation Changes in Emacs 24.4 |
7c3d167f | 26 | |
70c8f5ca | 27 | ** Emacs can now be compiled with ACL support. |
7c3d167f RF |
28 | This happens by default if a suitable support library is found at |
29 | build time, like libacl on GNU/Linux. To prevent this, use the | |
ffdc270a | 30 | configure option `--disable-acl'. |
a73fae1f | 31 | FIXME? Should be --without-acl? |
7c3d167f | 32 | |
70c8f5ca | 33 | ** Emacs can now be compiled with file notification support. |
671d4bfc GM |
34 | This happens by default if a suitable system library is found at |
35 | build time. To prevent this, use the configure option | |
e873a22e | 36 | `--without-file-notification'. See below for file-notify features. |
671d4bfc | 37 | FIXME? This feature is not available for the Nextstep port. (?) |

70c8f5ca CY |
40 | ** The configure option `--without-compress-info' has been generalized, |
41 | and renamed to `--without-compress-install'. It now prevents compression | |
335142f9 GM |
42 | of _any_ files during installation. |
43 | ||
d65a92bb | 44 | --- |
70c8f5ca | 45 | ** The configure option `--with-crt-dir' has been removed. |
a22359a7 | 46 | It is no longer needed, as the crt*.o files are no longer linked specially. |
f1e496a5 | 47 | |
d65a92bb | 48 | --- |
ae7bfbf5 JB |
49 | ** Directories passed to configure option `--enable-locallisppath' are |
50 | no longer created during installation. | |
51 | ||
70c8f5ca CY |
52 | ** Emacs can be compiled with zlib support. |
53 | If this library is present (which it normally is on most systems), the | |
54 | function `zlib-decompress-region' becomes available, which can | |
55 | decompress gzip- and zlib-format compressed data. | |
313546eb | 56 | |
9524a13d | 57 | --- |
8251c3f8 GM |
58 | ** Emacs for NS (Mac OS X, GNUstep) can be built with ImageMagick support. |
59 | This requires pkg-config to be available at configure time. | |

95a32efb | 62 | * Startup Changes in Emacs 24.4 |
c57b2d76 | 63 | |
17e0445b GM |
64 | +++ |
65 | ** When initializing `load-path', an empty element in the EMACSLOADPATH | |
66 | environment variable (either leading, e.g., ":/foo"; trailing, e.g., | |
67 | "/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default | |
68 | load-path (the one that would have been used if EMACSLOADPATH was unset). | |
69 | This makes it easier to _extend_ the load-path via EMACSLOADPATH | |
70 | (previously, EMACSLOADPATH had to specify the complete load-path, | |
71 | including the defaults). (In older versions of Emacs, an empty element | |
72 | was replaced by ".", so use an explicit "." now if that is what you want.) | |
73 | ||
a0833f62 GM |
74 | +++ |
75 | ** The -L option, which normally prepends its argument to load-path, | |
2df10228 GM |
76 | will instead append, if the argument begins with `:' (or `;' on MS Windows; |
77 | i.e., `path-separator'). | |
a0833f62 | 78 | |
06a4f110 GM |
79 | +++ |
80 | ** If you use either site-load.el or site-init.el to customize the dumped | |
81 | Emacs executable, any changes to `load-path' that these files make | |
82 | will no longer be present after dumping. To affect a permanent change | |
83 | to `load-path', use the `--enable-locallisppath' option of `configure'. | |
84 | ||
70c8f5ca CY |
85 | +++ |
86 | ** The user option `initial-buffer-choice' can now specify a function | |
87 | to set up the initial buffer. | |

95a32efb | 90 | * Changes in Emacs 24.4 |
c6c08d3f | 91 | |
d8a2993d TZ |
92 | +++ |
93 | ** New option `gnutls-verify-error', if non-nil, means that Emacs | |
94 | should reject SSL/TLS certificates that GnuTLS determines as invalid. | |
95 | (This option defaults to nil at present, but this is expected to change | |
96 | in a future release.) | |
97 | ||
0a12fca0 EZ |
98 | +++ |
99 | ** Emacs now supports menus on text-mode terminals. | |
100 | If the terminal supports a mouse, clicking on the menu bar, or on | |
101 | sensitive portions of the mode line or header line, will drop down the | |
102 | menu defined at that position. Likewise, clicking C-mouse-2 or | |
103 | C-mouse-2 or C-mouse-3 on the text area will pop up the menus defined | |
104 | for those locations. | |
105 | ||
106 | If the text terminal does not support a mouse, you can activate the | |
107 | first menu-bar menu by typing F10, which invokes `menu-bar-open'. | |
108 | ||
109 | If you want the previous behavior, whereby F10 invoked `tmm-menubar', | |
110 | customize the option `tty-menu-open-use-tmm' to a non-nil value. | |
f8b18150 GM |
111 | (Typing M-` always invokes `tmm-menubar', even if `tty-menu-open-use-tmm' |
112 | is nil.) | |
0a12fca0 | 113 | |
a34a0ac8 | 114 | +++ |
70c8f5ca CY |
115 | ** The *Messages* buffer is created in `messages-buffer-mode', |
116 | a new major mode, with read-only status. Any code that might create | |
117 | the *Messages* buffer should call the function `messages-buffer' to do | |
118 | so and set up the mode. | |
61a5bb85 | 119 | |
70c8f5ca | 120 | ** Emacs now supports ACLs (access control lists). |
7c3d167f RF |
121 | +++ |
122 | *** Emacs preserves the ACL entries of files when backing up. | |
123 | +++ | |
124 | *** New functions `file-acl' and `set-file-acl' get and set the ACL | |
66447e07 EZ |
125 | entries of a file. On GNU/Linux, the POSIX ACL interface is used via |
126 | libacl. On MS-Windows, the NT Security APIs are used to emulate the | |
127 | POSIX ACL interfaces. | |
7c3d167f | 128 | |
4e3f9230 YM |
129 | ** Multi-monitor support has been added. |
130 | ||
131 | *** New functions `display-monitor-attributes-list' and | |
132 | `frame-monitor-attributes' can be used to obtain information about | |
133 | each physical monitor on multi-monitor setups. | |
134 | ||
cf13177e YM |
135 | *** The functions `display-pixel-width' and `display-pixel-height' now |
136 | behave consistently among the platforms: they return the pixel width | |
137 | or height for all physical monitors associated with the given display | |
950fb38d | 138 | as if they were on X11. To get information for each physical |
cf13177e YM |
139 | monitor, use the new functions above. Similar notes also apply to |
140 | `x-display-pixel-width', `x-display-pixel-height', `display-mm-width', | |
141 | `display-mm-height', `x-display-mm-width', and `x-display-mm-height'. | |
142 | ||
70c8f5ca CY |
143 | +++ |
144 | ** The cursor stops blinking after 10 blinks (by default) on X and NS. | |
145 | You can change the default by customizing `blink-cursor-blinks'. | |
61e56e2c | 146 | |
70c8f5ca CY |
147 | +++ |
148 | ** In keymaps where SPC scrolls forward, S-SPC now scrolls backward. | |
149 | This affects View mode, etc. | |
150 | ||
151 | ** Help changes | |
f88ac3bb | 152 | |
98104aea | 153 | +++ |
70c8f5ca CY |
154 | *** The command `apropos-variable' is renamed to `apropos-user-option'. |
155 | `apropos-user-option' shows all user options while `apropos-variable' | |
156 | shows all variables. When called with a universal prefix argument, | |
157 | the two commands swap their behaviors. When `apropos-do-all' is | |
158 | non-nil, they output the same results. | |
18c26d81 | 159 | |
70c8f5ca CY |
160 | +++ |
161 | *** The key `?' now describes prefix bindings, like `C-h'. | |
6585d561 | 162 | |
6faf982a | 163 | --- |
8251c3f8 | 164 | *** The command `describe-function' has been extended for EIEIO. |
3ca34b22 | 165 | Running it on constructors will show a full description of the |
d6a62260 | 166 | generated class. For generic functions, it will show all |
3ca34b22 DE |
167 | implementations together with links to the source. The old commands |
168 | `describe-class', `describe-constructor' and `describe-generic' were | |
169 | removed. | |
170 | ||
44e76f9d GM |
171 | --- |
172 | *** The function `quail-help' is no longer an interactive command. | |
8251c3f8 | 173 | Use `C-h C-\' (`describe-input-method') instead. |
6950f152 | 174 | |
b29daf07 GM |
175 | ** ImageMagick |
176 | ||
4e7d26fc | 177 | +++ |
8251c3f8 | 178 | *** ImageMagick images now support the :max-width and :max-height keywords. |
b29daf07 | 179 | |
7b997b14 GM |
180 | +++ |
181 | *** When using `create-image' with image data, you can pass a :format | |
182 | attribute (via the property-list argument) in order to help | |
183 | ImageMagick detect the image type. The value should be a MIME | |
184 | content-type that is found in the new variable `image-format-suffixes'. | |
b29daf07 | 185 | |
70c8f5ca | 186 | ** Frame and window changes |
da9ea6d9 | 187 | |
70c8f5ca CY |
188 | +++ |
189 | *** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized', | |
190 | bound to <f11> and M-<f10>, respectively. | |
0a749fa0 | 191 | |
dc20a9d2 | 192 | +++ |
70c8f5ca CY |
193 | *** New hooks `focus-in-hook', `focus-out-hook'. |
194 | These are normal hooks run when an Emacs frame gains or loses input focus. | |
195 | ||
764ec9e5 | 196 | --- |
b7aa5ad6 MR |
197 | *** Emacs can now change frame sizes pixelwise. |
198 | When maximizing a frame or making it fullscreen, remaining extra pixels | |
199 | are no more given to the minibuffer, the rightmost fringe, or other | |
200 | unusable space, but are distributed among the text areas of the frame's | |
201 | windows. The new option `frame-resize-pixelwise', when non-nil, makes | |
202 | all frame size changes happen pixelwise and sets the corresponding size | |
203 | hints for the window manager. | |
204 | ||
205 | --- | |
206 | *** Emacs can now change window sizes pixelwise. | |
207 | Mouse-dragging a modeline or window divider now changes the size of | |
208 | adjacent windows pixelwise. The new option `window-resize-pixelwise', | |
209 | when non-nil, automatically makes functions like `balance-windows-area' | |
210 | or `fit-window-to-buffer' resize windows pixelwise. Most functions for | |
211 | resizing or accessing sizes of windows now have an additional argument | |
212 | which allows to apply changes or return values in pixels instead of | |
213 | lines/columns. | |
214 | ||
215 | --- | |
216 | *** Emacs can now draw dividers between adjacent windows. To put | |
217 | dividers between side-by-side/vertically stacked windows customize the | |
218 | frame parameters `right-divider-width' and `bottom-divider-width' to | |
219 | some positive integer. You can drag dividers with the mouse (they show | |
220 | a corresponding cursor when the mouse hovers over them). You can change | |
221 | the appearance of dividers by customizing the faces `window-divider', | |
222 | `window-divider-first-pixel', and `window-divider-last-pixel'. The last | |
223 | two are useful to provide a 3D effect, or to better distinguish dividers | |
224 | from surrounding display objects. | |
225 | ||
226 | --- | |
227 | *** New functions are provided to return the pixel sizes of window | |
228 | components, namely `window-scroll-bar-width', `window-mode-line-height' | |
229 | `window-header-line-height', `window-right-divider-width' and | |
230 | `window-bottom-divider-width'. | |
231 | ||
232 | --- | |
233 | *** The new function `window-text-pixel-size' returns the size of the | |
234 | text of a window's buffer in pixels. This allows functions like | |
235 | `fit-frame-to-buffer' and `fit-window-to-buffer' to accurately fit a | |
236 | window to its buffer as it will be displayed. | |
237 | ||
238 | --- | |
239 | *** `fit-window-to-buffer' can now resize windows horizontally. | |
240 | This behavior is controlled by the new option | |
241 | `fit-window-to-buffer-horizontally'. | |
242 | ||
243 | --- | |
244 | *** `fit-frame-to-buffer' can now fit frames in both directions. | |
245 | This behavior is controlled by the option `fit-frame-to-buffer' which | |
246 | tells in which direction(s) the frame shall be fit. The new options | |
247 | `fit-frame-to-buffer-margins' and `fit-frame-to-buffer-sizes' allow to | |
248 | control the size of the frame and its position on screen. | |
249 | ||
250 | --- | |
251 | *** Temp Buffer Resize Mode can now adjust height and width of windows | |
252 | and frames. `temp-buffer-resize-mode' is now able to adjust the height | |
253 | and the width of a window displaying a temporary buffer. The new option | |
254 | `temp-buffer-max-width' allows to control the width of temporary buffer | |
255 | windows. Moreover, if the new option `fit-frame-to-buffer' is non-nil | |
256 | and the buffer appears in the root window of a frame, Temp Buffer Resize | |
257 | Mode will try to adjust width and/or height of the frame. | |
764ec9e5 | 258 | |
70c8f5ca CY |
259 | --- |
260 | *** `split-window' is now a non-interactive function, not a command. | |
261 | As a command, it was a special case of `C-x 2' (`split-window-below'), | |
262 | and as such superfluous. After being reimplemented in Lisp, its | |
263 | interactive form was mistakenly retained. | |
4f0552c2 | 264 | |
b7aa5ad6 MR |
265 | --- |
266 | *** The functions `window-size' and `window-total-size' now have an | |
267 | optional argument to return a rounded size value. | |
268 | ||
269 | --- | |
270 | *** `window-state-put' now allows to put a window state into internal | |
271 | windows too. | |
272 | ||
daef8ab1 | 273 | +++ |
70c8f5ca CY |
274 | *** New option `scroll-bar-adjust-thumb-portion'. |
275 | Available only on X, this option allows to control over-scrolling | |
276 | using the scroll bar (i.e. dragging the thumb down even when the end | |
277 | of the buffer is visible). | |
278 | ||
b7aa5ad6 MR |
279 | --- |
280 | *** New basic action function `display-buffer-in-previous-window' has | |
281 | `display-buffer' display a buffer in a window previously showing that | |
282 | buffer. | |
283 | ||
284 | --- | |
285 | *** New basic action function `display-buffer-at-bottom' has | |
286 | `display-buffer' choose or make a window at the bottom of the selected | |
287 | frame. | |
288 | ||
70c8f5ca | 289 | ** Lisp evaluation changes |
75a1e034 | 290 | +++ |
70c8f5ca CY |
291 | *** `eval-defun' on an already defined defcustom calls the :set function, |
292 | if there is one. | |
293 | ||
c51e81ef | 294 | +++ |
d856c4a9 | 295 | *** The commands `eval-expression' (`M-:'), `eval-last-sexp' (`C-x C-e'), |
c51e81ef GM |
296 | and `eval-print-last-sexp' (`C-j' in Lisp Interaction mode) can take a |
297 | zero prefix argument. This disables truncation of lists in the output, | |
298 | equivalent to setting `(eval-expression-)print-length' and | |
4d000e69 | 299 | `(eval-expression-)print-level' to nil. Additionally, it causes integers |
c51e81ef | 300 | to be printed in other formats (octal, hexadecimal, and character). |
70c8f5ca | 301 | |
a8cb4247 | 302 | --- |
6bbc0c84 GM |
303 | *** New hook `eval-expression-minibuffer-setup-hook' run by |
304 | `eval-expression' on entering the minibuffer. | |

da048127 | 308 | |
2cd12d28 | 309 | +++ |
314ffdb1 | 310 | ** `cache-long-line-scans' is now non-nil, and renamed to `cache-long-scans', |
70c8f5ca | 311 | because it affects caching of paragraph scanning results as well. |
314ffdb1 | 312 | There is no reason to set this to nil except for debugging purposes. |
4e36a6a6 | 313 | |
70c8f5ca CY |
314 | --- |
315 | ** The option `set-mark-default-inactive' has been deleted. | |
316 | This unfinished feature was introduced by accident in Emacs 23.1; | |
317 | simply disabling Transient Mark mode does the same thing. | |
318 | ||
6faf982a | 319 | --- |
8251c3f8 | 320 | ** The default value of `comment-use-global-state' is now t, |

337 | ** Indentation changes | |
338 | ||
339 | +++ | |
340 | *** The behavior of `C-x TAB' (`indent-rigidly') has changed. | |
341 | When invoked without a prefix argument, it now activates a transient | |
342 | mode in which typing <left>, <right>, <S-left>, and <S-right> adjusts | |
343 | the text indentation in the region. Typing any other key resumes | |
344 | normal editing behavior. | |
3472b6c6 | 345 | |

8251c3f8 | 580 | *** New option `electric-pair-open-newline-between-pairs', enabled by default. |
3b8d5131 JT |
581 | In `electric-pair-mode', inserting a newline between adjacent pairs |

620 | This feature has been extended to subcommands and options that make a | |

1404 | ** Changes in encoding and decoding of text |
1405 | ||
1406 | --- | |
1407 | *** New coding-system `prefer-utf-8'. | |
1408 | This is like `undecided' but prefers UTF-8 on decoding if the text to | |
1409 | be decoded does not contain any invalid UTF-8 sequences. On encoding, | |
1410 | any non-ASCII characters are automatically encoded as UTF-8. | |
1411 | ||
1412 | --- | |
1413 | *** New attributes of coding-systems whose type is `undecided'. | |
1414 | Two new attributes, `:inhibit-null-byte-detection' and | |
1415 | `:inhibit-iso-escape-detection', determine how to detect encoding of | |
1416 | text that includes null bytes and ISO-2022 escape sequences, | |
1417 | respectively. Each of these attributes can be either nil, zero, or | |
1418 | t. If it is t, decoding text ignores null bytes and, respectively, | |
1419 | ISO-2022 sequences. If it is nil, null bytes cause text to be decoded | |
1420 | with no-conversion and ISO-2022 sequences cause Emacs to assume the | |
1421 | text is encoded in one of the ISO-2022 encodings, such as | |
1422 | iso-2022-7bit. If the value is zero, Emacs consults the variables | |
1423 | inhibit-null-byte-detection and inhibit-iso-escape-detection, which | |
1424 | see. | |
1425 | The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer | |
1426 | UTF-8 encoding and decoding, whenever possible. | |
1427 | ||
1428 | These attributes are only meaningful for coding-systems of type | |
1429 | `undecided'. (The type of a coding-system is determined by its | |
1430 | `:coding-type' attribute and can be accessed by calling the | |
1431 | `coding-system-type' function.) | |

1468 | Using the Posix configure script and Makefile's also means a change in | |

1495 | Setting it has no effect, and %t in the mode-line format is ignored. | |
1496 | Likewise, `file-name-buffer-file-type-alist' is now obsolete, and | |
1497 | modifying it has no effect. | |

343a2aef EZ |
1502 | edited in another Emacs session or by another user. See the node |

1506 | ** New Core Text based font backend for Mac OS X 10.5 and newer. |
1507 | GNUstep and Mac OS X 10.4 use the old font backend. | |
1508 | To use the old backend by default, do on the command line: | |

c57b2d76 | 1511 | ** Improved fullscreen support on Mac OS X. |
2d3c36db GM |
1512 | Emacs supports both native (Mac OS X 10.7 and newer) and "old style" fullscreen. |
1513 | Customize `ns-use-native-fullscreen' to change the style. | |
1514 | For Mac OS X 10.7 and newer, native is the default. | |

6bc66c10 | 1523 | ** The default X toolkit is now Gtk+ version 3. |
823b2fb6 GM |
1524 | If you don't pass `--with-x-toolkit' to configure, or if you use |
1525 | `--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try | |
1526 | to build with Gtk+ version 3, and if that fails, try Gtk+ version 2. | |
d71a6517 | 1527 | You can explicitly require a specific version by passing |
823b2fb6 | 1528 | `--with-x-toolkit=gtk2' or `--with-x-toolkit=gtk3' to configure. |
da3d2105 | 1529 | |
6bc66c10 | 1530 | ** New configure option `--enable-link-time-optimization', to utilize |
da3d2105 DA |
1531 | an appropriate feature provided by GCC since version 4.5.0. |
1532 | ||
33cb2043 GM |
1533 | ** New configure option `--without-all' to disable most of the optional |
1534 | features (image support, etc.) that are normally enabled by default. | |
b8df54ff | 1535 | |
33cb2043 GM |
1536 | ** New configure option `--enable-gcc-warnings' (for developing/debugging |
1537 | Emacs). If building with GCC, this enables compile-time checks that | |
64420fcd GM |
1538 | warn/give errors about possibly-questionable C code. On a recent GNU |
1539 | system there should be no warnings; on older and on non-GNU systems | |
1540 | the results may be useful to developers. | |
b8df54ff | 1541 | |
823b2fb6 | 1542 | ** The configure option `--enable-use-lisp-union-type' has been |
6bc66c10 | 1543 | renamed to `--enable-check-lisp-object-type', as the resulting |
d71a6517 GM |
1544 | Lisp_Object type no longer uses a union to implement the compile time |
1545 | check that this option enables. | |
1546 | ||
823b2fb6 | 1547 | ** The configure option `--disable-maintainer-mode' has been removed, |
501390c5 PE |
1548 | as it was confusingly-named and rarely useful. |
1549 | ||
f14a4380 GM |
1550 | ** The configure options `--program-prefix', `--program-suffix', and |
1551 | `--program-transform-name' apply to more than just the installed | |
1552 | binaries. Now they also affect the man pages, icons, and the | |
1553 | etc/emacs.desktop file; but not the info pages, since this would break | |
1554 | links between the various manuals. | |
1a9c6830 | 1555 | |
823b2fb6 GM |
1556 | ** You can use `NO_BIN_LINK=t make install' to prevent the installation |
1557 | overwriting "emacs" in the installation bin/ directory with a link | |
6bc66c10 | 1558 | to "emacs-VERSION". |
823b2fb6 | 1559 | |
a4a18b8b GM |
1560 | ** Emacs uses libtinfo in preference to libncurses, if available. |
1561 | ||
187e9b90 GM |
1562 | ** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and |
1563 | /usr/pkg/lib to the linker search path. You must add them yourself if | |
1564 | you want them. | |
1565 | ||
6bc66c10 | 1566 | ** The standalone scripts `rcs-checkin' and `vcdiff' have been removed |
276d5f5d GM |
1567 | (from the bin and libexec directories, respectively). The former is |
1568 | no longer relevant, the latter is replaced by lisp (in vc-sccs.el). | |

823b2fb6 | 1575 | been adding them there, put them somewhere else; e.g., site-lisp. |

c89926a5 | 1583 | |
6bc66c10 | 1584 | *** `C-h f' (`describe-function') can now perform autoloading. |
c89926a5 CY |
1585 | When this command is called for an autoloaded function whose docstring |
1586 | contains a key substitution construct, that function's library is | |
1587 | automatically loaded, so that the documentation can be shown | |
1588 | correctly. To disable this, set `help-enable-auto-load' to nil. | |
1589 | ||
1590 | *** `C-h f' now reports previously-autoloaded functions as "autoloaded", | |
1591 | even after their associated libraries have been loaded (and the | |
1592 | autoloads have been redefined as functions). | |
1593 | ||
6bc66c10 | 1594 | ** ImageMagick |
cd996018 | 1595 | |
6bc66c10 GM |
1596 | *** Images displayed via ImageMagick now support transparency and the |
1597 | :background image specification property. | |
cd996018 | 1598 | |
6bc66c10 | 1599 | *** When available, ImageMagick support is automatically enabled. |
c505aaeb CY |
1600 | It is no longer necessary to call `imagemagick-register-types' |
1601 | explicitly to install ImageMagick image types; that function is called | |
7d806bfe | 1602 | automatically at startup, or when customizing an imagemagick- option. |
2f940384 | 1603 | |
c505aaeb | 1604 | *** Setting `imagemagick-types-inhibit' to t now disables the use of |
823b2fb6 GM |
1605 | ImageMagick to view images. (You must call `imagemagick-register-types' |
1606 | afterwards if you do not use customize to change this.) | |
2f940384 | 1607 | |
7afbaca4 | 1608 | *** The new variable `imagemagick-enabled-types' also affects which |
60b5f187 GM |
1609 | ImageMagick types are treated as images. The function |
1610 | `imagemagick-filter-types' returns the list of types that will be | |
1611 | treated as images. | |
c505aaeb | 1612 | |
6bc66c10 GM |
1613 | ** Minibuffer |
1614 | ||
1615 | *** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the | |
1616 | next and previous path separator, respectively. | |
c505aaeb | 1617 | |
6bc66c10 GM |
1618 | *** `minibuffer-electric-default-mode' can shorten "(default ...)" to "[...]" |
1619 | in minibuffer prompts. Just set `minibuffer-eldef-shorten-default' | |
1620 | non-nil before enabling the mode. | |
1621 | ||
1622 | ** Mode line | |
1623 | ||
1624 | *** New option `mode-line-default-help-echo' specifies the help text | |
1625 | (shown in a tooltip or in the echo area) for any part of the mode line | |
1626 | that does not have its own specialized help text. | |
1627 | ||
1628 | *** You can now click mouse-3 in the coding system indicator to invoke | |
1629 | `set-buffer-file-coding-system'. | |
1630 | ||
1631 | ** Server and client | |
2f940384 | 1632 | |
f938eda9 CY |
1633 | *** emacsclient now obeys string values for `initial-buffer-choice', |
1634 | if it is told to open a new frame without specifying any file to visit | |
1635 | or expression to evaluate. | |
db80bdc8 | 1636 | |
f938eda9 | 1637 | *** New option `server-auth-key' specifies a shared server key. |
f938eda9 CY |
1638 | |
1639 | ** Emacs now generates backtraces on fatal errors. | |
1640 | On encountering a fatal error, Emacs now outputs a textual description | |
1641 | of the fatal signal, and a short backtrace on platforms like glibc | |
5248293f | 1642 | that support backtraces. |
2e2d2a13 | 1643 | |
6bc66c10 GM |
1644 | ** `C-x C-q' is now bound to the new minor mode `read-only-mode'. |
1645 | This minor mode replaces `toggle-read-only', which is now obsolete. | |
1646 | ||
1647 | ** Most `y-or-n' prompts now allow you to scroll the selected window. | |
1648 | Typing `C-v' or `M-v' at a y-or-n prompt scrolls forward or backward | |
1649 | respectively, without exiting from the prompt. | |
1650 | ||
1651 | ** In the Package Menu, newly-available packages are listed as "new", | |
1652 | and sorted above the other "available" packages by default. | |
1653 | ||
9475054f | 1654 | ** If your Emacs was built from a repository checkout, the new variable |
0bfbd67c | 1655 | `emacs-bzr-version' contains information about the bzr revision used. |
de6ff46d | 1656 | |
6bc66c10 | 1657 | ** New option `create-lockfiles' specifies usage of lockfiles. |
f938eda9 CY |
1658 | It defaults to t. Changing it to nil inhibits the creation of lock |
1659 | files (use this with caution). | |
dc0f75c8 | 1660 | |
6bc66c10 GM |
1661 | ** New option `enable-remote-dir-locals', if non-nil, allows directory-local |
1662 | variables on remote hosts. | |
21ffb35a | 1663 | |
f85f636a CY |
1664 | ** The entry for PCL-CVS has been removed from the Tools menu. |
1665 | The PCL-CVS commands are still available via the keyboard. | |
1666 | ||
6bc66c10 GM |
1667 | ** Using "unibyte: t" in Lisp source files is obsolete. |
1668 | Use "coding: raw-text" instead. | |
1669 | ||
e78e7e48 CY |
1670 | ** In the buffer made by `M-x report-emacs-bug', the `C-c m' binding |
1671 | has been changed to `C-c M-i' (`report-emacs-bug-insert-to-mailer'). | |
1672 | The previous binding, introduced in Emacs 24.1, was a mistake, because | |
1673 | `C-c LETTER' bindings are reserved for user customizations. | |
1674 | ||
6bc66c10 | 1675 | ** Internationalization |
2f940384 | 1676 | |
f938eda9 | 1677 | *** New language environment: Persian. |
2f940384 | 1678 | |
f938eda9 CY |
1679 | *** New input method `vietnamese-vni'. |
1680 | ||
6bc66c10 | 1681 | ** Nextstep (GNUstep / Mac OS X) port |
2f940384 | 1682 | |
823b2fb6 | 1683 | *** Support for fullscreen and the frame parameter fullscreen. |
2f940384 | 1684 | |
1a9c6830 GM |
1685 | *** A file dialog is used for open/save operations initiated from the |
1686 | menu/toolbar. | |

6bc66c10 | 1691 | ** Search and Replace |
d39d3c8e | 1692 | |
f938eda9 CY |
1693 | *** Non-regexp Isearch now performs "lax" space matching. |
1694 | Each sequence of spaces in the supplied search string may match any | |
1695 | sequence of one or more whitespace characters, as specified by the | |
1696 | variable `search-whitespace-regexp'. (This variable is also used by a | |
823b2fb6 | 1697 | similar existing feature for regexp Isearch.) |
2f940384 | 1698 | |
f938eda9 CY |
1699 | *** New Isearch command `M-s SPC' toggles lax space matching. |
1700 | This applies to both ordinary and regexp Isearch. | |
2f940384 | 1701 | |
f938eda9 CY |
1702 | *** New option `replace-lax-whitespace'. |
1703 | If non-nil, `query-replace' uses flexible whitespace matching too. | |
1704 | The default is nil. | |
2f940384 | 1705 | |
b9cb2387 JL |
1706 | *** Global `M-s _' starts a symbol (identifier) incremental search, |
1707 | and `M-s _' in Isearch toggles symbol search mode. | |
1708 | `M-s c' in Isearch toggles search case-sensitivity. | |
1709 | ||
6bc66c10 | 1710 | ** Navigation commands |
48de8b12 | 1711 | |
6bc66c10 GM |
1712 | *** New binding `M-g c' for `goto-char'. |
1713 | ||
1714 | *** New binding `M-g TAB' for `move-to-column'. | |
1715 | ||
1716 | *** `M-g TAB' (`move-to-column') prompts for a column number if called | |
1717 | interactively with no prefix arg. Previously, it moved to column 1. | |
1718 | ||
1719 | ** New option `yank-handled-properties' allows processing of text | |
1720 | properties on yanked text, in ways that are more general than just | |
1721 | removing them (as is done by `yank-excluded-properties'). | |
48de8b12 | 1722 | |
48de8b12 CY |
1723 | ** New option `delete-trailing-lines' specifies whether |
1724 | M-x delete-trailing-whitespace should delete trailing lines at the end | |
1725 | of the buffer. It defaults to t. | |
1726 | ||
f938eda9 | 1727 | ** `C-u M-=' now counts lines/words/characters in the entire buffer. |
826b3235 | 1728 | |
48de8b12 CY |
1729 | ** `C-x 8 RET' is now bound to `insert-char', which is now a command. |
1730 | `ucs-insert' is now an obsolete alias for `insert-char'. | |
b2459884 | 1731 | |
48de8b12 CY |
1732 | ** The `z' key no longer has a binding in most special modes. |
1733 | It used to be bound to `kill-this-buffer', but `z' is too easy to | |
1734 | accidentally type. | |
f938eda9 | 1735 | |
6bc66c10 GM |
1736 | ** New command `C-x r M-w' (`copy-rectangle-as-kill'). |
1737 | It copies the region-rectangle as the last rectangle kill. | |
f938eda9 | 1738 | |
6bc66c10 | 1739 | ** Registers |
f938eda9 | 1740 | |
823b2fb6 | 1741 | *** `C-x r +' is now overloaded to invoke `append-to-register'. |
f938eda9 | 1742 | |
f938eda9 | 1743 | *** New option `register-separator' specifies the register containing |
823b2fb6 GM |
1744 | the text to put between collected texts for use with |
1745 | M-x append-to-register and M-x prepend-to-register. | |

ae4969c2 | 1749 | |
6bc66c10 | 1750 | ** Common Lisp emulation (CL) |
f938eda9 | 1751 | |
89660017 | 1752 | *** CL's main entry is now (require 'cl-lib). |
823b2fb6 GM |
1753 | `cl-lib' is like the old `cl' except that it uses the namespace cleanly; |
1754 | i.e., all its definitions have the "cl-" prefix (and internal definitions | |
1755 | use the "cl--" prefix). | |
7c1898a7 | 1756 | |
823b2fb6 GM |
1757 | If `cl' provided a feature under the name `foo', then `cl-lib' |
1758 | provides it under the name `cl-foo' instead; with the exceptions of the | |
1759 | few `cl' definitions that had to use `foo*' to avoid conflicts with | |
1760 | pre-existing Elisp entities. These have been renamed to `cl-foo' | |
1761 | rather than `cl-foo*'. | |
7c1898a7 | 1762 | |
92246540 | 1763 | The old `cl' is now deprecated and is mainly just a bunch of aliases that |
823b2fb6 | 1764 | provide the old, non-prefixed names. Some exceptions are listed below: |
7c1898a7 | 1765 | |
89660017 SM |
1766 | *** `cl-flet' is not like `flet' (which is deprecated). |
1767 | Instead it obeys the behavior of Common-Lisp's `flet'. | |
e8693c96 GM |
1768 | In particular, in cl-flet function definitions are lexically scoped, |
1769 | whereas in flet the scoping is dynamic. | |
89660017 SM |
1770 | |
1771 | *** `cl-labels' is slightly different from `labels'. | |
823b2fb6 GM |
1772 | The difference is that it relies on the `lexical-binding' machinery |
1773 | (as opposed to the `lexical-let' machinery used previously) to capture | |
1774 | definitions in closures, so such closures will only work if `lexical-binding' | |
1775 | is in use. | |
89660017 | 1776 | |
f94b04fc | 1777 | *** `cl-letf' is not exactly like `letf'. |
4ddedf94 GM |
1778 | The only difference is in details that relate to some deprecated usage |
1779 | of `symbol-function' in place forms. | |
f94b04fc | 1780 | |
89660017 | 1781 | *** `progv' was rewritten to use the `let' machinery. |
823b2fb6 GM |
1782 | A side effect is that variables without corresponding values are bound |
1783 | to nil rather than being made unbound. | |
89660017 | 1784 | |
9512f820 GM |
1785 | *** The following methods of extending `setf' are obsolete |
1786 | (use features from gv.el instead): | |
1787 | `define-modify-macro' (use `gv-letplace') | |
031b2ea7 GM |
1788 | `defsetf' (use `gv-define-simple-setter' or `gv-define-setter') |
1789 | `define-setf-expander' (use `gv-define-setter' or `gv-define-expander') | |
2b4da3ff | 1790 | `get-setf-method' no longer exists (see "Incompatible Lisp Changes") |
f94b04fc | 1791 | |
6bc66c10 | 1792 | ** Diff mode |
f938eda9 | 1793 | |
6bc66c10 GM |
1794 | *** Changes are now highlighted using the same color scheme as in |
1795 | modern VCSes. Deletions are displayed in red (new faces | |
1796 | `diff-refine-removed' and `smerge-refined-removed', and new definition | |
1797 | of `diff-removed'), insertions in green (new faces `diff-refine-added' | |
1798 | and `smerge-refined-added', and new definition of `diff-added'). | |
f938eda9 | 1799 | |
6bc66c10 GM |
1800 | *** The variable `diff-use-changed-face' defines whether to use the |
1801 | face `diff-changed', or `diff-removed' and `diff-added' to highlight | |
1802 | changes in context diffs. | |
2f940384 | 1803 | |
6bc66c10 GM |
1804 | *** The new command `diff-delete-trailing-whitespace' removes trailing |
1805 | whitespace introduced by a diff. | |
f938eda9 | 1806 | |
6bc66c10 GM |
1807 | ** Ediff now uses the same color scheme as Diff mode. |
1808 | ||
1809 | ** Python mode | |
1810 | ||
1811 | A new version of python.el, which provides several new features, including: | |
1812 | per-buffer shells, better indentation, Python 3 support, and improved | |
1813 | shell-interaction compatible with iPython (and virtually any other | |
1814 | text based shell). | |
1815 | ||
1816 | *** Some user options have been replaced/renamed, including (old -> new): | |
1817 | **** python-indent -> python-indent-offset | |
1818 | **** python-guess-indent -> python-indent-guess-indent-offset | |
1819 | **** python-pdbtrack-do-tracking-p -> python-pdbtrack-activate | |
1820 | **** python-use-skeletons -> python-skeleton-autoinsert | |
1821 | ||
1822 | *** Some user options have been removed, including: | |
1823 | ||
1824 | **** `python-indent-string-contents': Strings are never indented. | |
1825 | ||
1826 | **** `python-honour-comment-indentation': | |
d5b1b1aa | 1827 | Comments are always considered as indentation markers. |
6bc66c10 GM |
1828 | |
1829 | **** `python-continuation-offset': Indentation is automatically | |
1830 | calculated in a pep8 compliant way depending on the context. | |

6bc66c10 GM |

ce7b18ec CY |

f938eda9 | 2133 | |
6bc66c10 GM |
2134 | ** SQL mode has a new option `sql-db2-escape-newlines'. |
2135 | If non-nil, newlines sent to the command interpreter will be escaped | |
2136 | by a backslash. The default does not escape the newlines and assumes | |
2137 | that the sql statement will be terminated by a semicolon. | |
f938eda9 | 2138 | |
6bc66c10 GM |
2139 | ** New command `tabulated-list-sort', bound to `S' in Tabulated List mode |

2a1e2476 | 2192 | * Incompatible Lisp Changes in Emacs 24.3 |
b4d3bc10 | 2193 | |
6bc66c10 GM |
2194 | ** Docstrings starting with `*' no longer indicate user options. |
2195 | Only variables defined using `defcustom' are considered user options. | |
2196 | The function `user-variable-p' is now an obsolete alias for | |
2197 | `custom-variable-p'. | |
090cf9db | 2198 | |
6bc66c10 GM |
2199 | ** The return values of `defalias', `defun' and `defmacro' have changed, |
2200 | and are now undefined. For backwards compatibility, `defun' and | |
2201 | `defmacro' currently return the name of the newly defined | |
2202 | function/macro, but this should not be relied upon. | |
090cf9db | 2203 | |
823b2fb6 GM |
2204 | ** `random' by default now returns a different random sequence in |
2205 | every Emacs run. Use `(random S)', where S is a string, to set the | |
0e23ef9d PE |
2206 | random seed to a value based on S, in order to get a repeatable |
2207 | sequence in later calls. | |
2208 | ||
d32e47af LM |
2209 | ** If the NEWTEXT arg to `replace-match' contains a substring "\?", |
2210 | that substring is inserted literally even if the LITERAL arg is | |
2211 | non-nil, instead of causing an error to be signaled. | |
2212 | ||
2cec368c MR |
2213 | ** `select-window' now always makes the window's buffer current. |
2214 | It does so even if the window was selected before. | |
2215 | ||
6bc66c10 GM |
2216 | ** The function `x-select-font' can return a font spec, instead of a |
2217 | font name as a string. Whether it returns a font spec or a font name | |
2218 | depends on the graphical library. | |
bbf908bc | 2219 | |
eeddc531 CY |
2220 | ** `face-spec-set' no longer sets frame-specific attributes when the |
2221 | third argument is a frame (that usage was obsolete since Emacs 22.2). | |
2222 | ||
6bc66c10 | 2223 | ** `set-buffer-multibyte' now signals an error in narrowed buffers. |
a59d531e | 2224 | |
ab7f1c43 GM |
2225 | ** The CL package's `get-setf-method' function no longer exists. |
2226 | Generalized variables are now part of core Emacs Lisp, and implemented | |
2227 | differently to the way cl.el used to do it. It is not possible to | |
2228 | define a compatible replacement for `get-setf-method'. See the file | |
2229 | gv.el for internal details of the new implementation. | |
2230 | ||
6bc66c10 GM |
2231 | ** The arguments of `dbus-register-signal' are no longer just strings, |
2232 | but keywords or keyword-string pairs. The old argument list will | |
2233 | still be supported for Emacs 24.x. | |
72b255c7 | 2234 | |
6bc66c10 | 2235 | ** Miscellaneous name changes |
823b2fb6 GM |
2236 | Some Lisp symbols have been renamed to correct their spelling, |
2237 | or to be more consistent with standard Emacs terminology. | |
72b255c7 | 2238 | |
72b255c7 | 2239 | *** Renamed functions |
72b255c7 PE |
2240 | **** hangul-input-method-inactivate -> hangul-input-method-deactivate |

2246 | viper-deactivate-input-method-action | |
2247 | **** ucs-input-inactivate -> ucs-input-deactivate | |
2248 | ||
2249 | *** Renamed hooks | |
2250 | The old hooks are still supported for backward compatibility, but they | |
2251 | are deprecated and will be removed eventually. | |
72b255c7 PE |
2252 | **** input-method-inactivate-hook -> input-method-deactivate-hook |
2253 | **** robin-inactivate-hook -> robin-deactivate-hook | |
2254 | **** quail-inactivate-hook -> quail-deactivate-hook | |
2255 | ||
6bc66c10 | 2256 | *** Renamed variables |
72b255c7 PE |
2257 | **** follow-deactive-menu -> follow-inactive-menu |
2258 | **** inactivate-current-input-method-function -> | |
2259 | deactivate-current-input-method-function | |

02969baf GM |
2261 | ** Some obsolete functions, variables, and faces have been removed: |
2262 | *** `last-input-char', `last-command-char', `unread-command-char' | |
78f3273a CY |
2263 | *** `facemenu-unlisted-faces' |

a5f2b6ec | 2273 | *** `cvs-commit-buffer-require-final-newline' |
63820c5c | 2274 | (use `log-edit-require-final-newline' instead) |
a5f2b6ec CY |
2275 | *** `cvs-changelog-full-paragraphs' |

93e0bed6 | 2283 | * Lisp Changes in Emacs 24.3 |
ef24141c | 2284 | |
2ee3d7f0 | 2285 | ** CL-style generalized variables are now in core Elisp. |
f938eda9 | 2286 | `setf' is autoloaded; `push' and `pop' accept generalized variables. |
ebdbfb95 GM |
2287 | You can define your own generalized variables using `gv-define-simple-setter', |
2288 | `gv-define-setter', etc. | |
2ee3d7f0 | 2289 | |
6bc66c10 GM |
2290 | ** Emacs tries to macroexpand interpreted (non-compiled) files during load. |
2291 | This can significantly speed up execution of non-byte-compiled code, | |
2292 | but can also bump into previously unnoticed cyclic dependencies. | |
2293 | These are generally harmless: they will simply cause the macro calls | |
2294 | to be left for later expansion (as before), but will result in a | |
2295 | warning ("Eager macro-expansion skipped due to cycle") describing the cycle. | |
2296 | You may wish to restructure your code so this does not happen. | |
2297 | ||
2298 | ** New sampling-based Elisp profiler. | |
2299 | Try M-x profiler-start, do some work, and then call M-x profiler-report. | |
2300 | When finished, use M-x profiler-stop. The sampling rate can be based on | |
2301 | CPU time or memory allocations. | |
2302 | ||
500fcedc SM |
2303 | ** `defun' also accepts a (declare DECLS) form, like `defmacro'. |
2304 | The interpretation of the DECLS is determined by `defun-declarations-alist'. | |
2305 | ||
6bc66c10 GM |
2306 | ** New macros `setq-local' and `defvar-local'. |
2307 | ||
2308 | ** Face underlining can now use a wave. | |
2f940384 | 2309 | |
6bc66c10 | 2310 | ** `read-regexp' has a new argument HISTORY; the first argument PROMPT |
cd996018 | 2311 | of `read-regexp' accepts a string ending with a colon and space, and its |
823b2fb6 | 2312 | second argument DEFAULTS can be a list of strings accessible via `M-n' |
cd996018 CY |
2313 | in the minibuffer ahead of other hard-coded useful regexp-related values. |
2314 | More commands use `read-regexp' now to read their regexp arguments. | |
2315 | ||
f938eda9 | 2316 | ** Completion |
500fcedc | 2317 | |
f938eda9 CY |
2318 | *** New function `completion-table-with-quoting' to handle completion |
2319 | in the presence of quoting, such as file completion in shell buffers. | |
f95e9344 | 2320 | |
f938eda9 CY |
2321 | *** New function `completion-table-subvert' to use an existing completion |
2322 | table, but with a different prefix. | |
2323 | ||
6bc66c10 | 2324 | ** Debugger |
f95e9344 | 2325 | |
f938eda9 CY |
2326 | *** New error type and new function `user-error'. |
2327 | These do not trigger the debugger. | |
f95e9344 | 2328 | |
57fc0fee GM |
2329 | *** New option `debugger-bury-or-kill', saying what to do with the |
2330 | debugger buffer when exiting debug. | |
45b82ad0 SM |
2331 | |
2332 | *** Set `debug-on-message' to enter the debugger when a certain | |
2333 | message is displayed in the echo area. This can be useful when trying | |
2334 | to work out which code is doing something. | |
2f940384 | 2335 | |
45b82ad0 SM |
2336 | *** New var `inhibit-debugger', automatically set to prevent accidental |
2337 | recursive invocations. | |
fa2bcf43 | 2338 | |
6bc66c10 | 2339 | ** Window handling |
2f940384 | 2340 | |
6bc66c10 GM |
2341 | *** New command `fit-frame-to-buffer' adjusts the frame height to |
2342 | fit the contents. | |
2f940384 | 2343 | |
6bc66c10 GM |
2344 | *** The command `fit-window-to-buffer' can adjust the frame height |
2345 | if the new option `fit-frame-to-buffer' is non-nil. | |
8e17c9ba | 2346 | |
7fe37cfc GM |
2347 | *** New macro `with-temp-buffer-window', similar to |
2348 | `with-output-to-temp-buffer'. | |
fa2bcf43 | 2349 | |
8e17c9ba MR |
2350 | *** `temp-buffer-resize-mode' no longer resizes windows that have been |
2351 | reused. | |
c5e28e39 | 2352 | |
823b2fb6 | 2353 | *** New option `switch-to-buffer-preserve-window-point' to restore a |
43bcfda6 | 2354 | window's point when switching buffers. |
7c82753d | 2355 | |
6bc66c10 GM |
2356 | *** New display action alist entries `window-height' and `window-width' |
2357 | specify the size of new windows created by `display-buffer'. | |
2358 | ||
2359 | *** New display action alist entry `pop-up-frame-parameters', if | |
2360 | non-nil, specifies frame parameters to give any newly-created frame. | |
7c82753d | 2361 | |
fa2bcf43 MR |
2362 | *** New display action alist entry `inhibit-switch-frame', if non-nil, |
2363 | tells display action functions to avoid changing which frame is | |
2364 | selected. | |
2f940384 | 2365 | |
fa2bcf43 MR |
2366 | *** New display action alist entry `previous-window', if non-nil, |
2367 | specifies window to reuse in `display-buffer-in-previous-window'. | |
2f940384 | 2368 | |
6bc66c10 GM |
2369 | *** New display action functions `display-buffer-below-selected', |
2370 | and `display-buffer-in-previous-window'. | |
2371 | ||
2372 | *** The functions `get-lru-window', `get-mru-window' and `get-largest-window' | |
2373 | now accept a third argument to avoid choosing the selected window. | |
2374 | ||
2375 | *** Additional values recognized for option `window-combination-limit'. | |
5938d519 | 2376 | |
77f1f99c CY |
2377 | *** The following variables are obsolete, as they can be replaced by |
2378 | appropriate entries in the `display-buffer-alist' function introduced | |
2379 | in Emacs 24.1: | |
823b2fb6 | 2380 | **** `dired-shrink-to-fit' |
77f1f99c | 2381 | **** `display-buffer-reuse-frames' |
823b2fb6 | 2382 | **** `display-buffer-function' |
77f1f99c | 2383 | **** `special-display-buffer-names' |

77f1f99c | 2385 | **** `special-display-function' |
823b2fb6 | 2386 | **** `special-display-regexps' |
77f1f99c | 2387 | |
ab0fa4e4 | 2388 | ** Time |
2f940384 | 2389 | |
ab0fa4e4 PE |
2390 | *** `current-time-string' no longer requires that its argument's year |
2391 | must be in the range 1000..9999. It now works with any year supported | |
2392 | by the underlying C implementation. | |
2f940384 | 2393 | |
f938eda9 CY |
2394 | *** `current-time' now returns extended-format time stamps |
2395 | (HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds. | |
2396 | PSEC is typically a multiple of 1000 on current machines. Other | |
823b2fb6 GM |
2397 | functions that use this format, such as `file-attributes' and |
2398 | `format-time-string', have been changed accordingly. Old-format time | |
f938eda9 | 2399 | stamps are still accepted. |
2f940384 | 2400 | |
823b2fb6 | 2401 | *** The format of timers in `timer-list' and `timer-idle-list' is now |
f938eda9 CY |
2402 | [TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS]. |
2403 | The PSECS slot is new, and uses picosecond resolution. It can be | |
823b2fb6 | 2404 | accessed via the new `timer--psecs' accessor. |
2f940384 | 2405 | |
c4132fd4 PE |
2406 | *** Last-modified time stamps in undo lists now are of the form |
2407 | (t HI-SECS LO-SECS USECS PSECS) instead of (t HI-SECS . LO-SECS). | |
2408 | ||
0058cae2 GM |
2409 | ** EIEIO |
2410 | ||
2411 | *** Improved security when handling persistent objects: | |
2412 | ||
2413 | **** `eieio-persistent-read' now features optional arguments for specifying | |
2414 | the class to load, as well as a flag stating whether subclasses are allowed; | |
2415 | if provided, other classes will be rejected by the reader. For | |
2416 | compatibility with existing code, if the class is omitted only a | |
2417 | warning is issued. | |
2418 | ||
2419 | **** New specialized reader for pulling in classes and signaling errors | |
2420 | without evaluation of suspicious code. | |
2421 | ||
2422 | **** All slots that contain objects must have a :type. Slots with lists | |
2423 | of objects must use a new type predicate for a list of an object type. | |
2424 | ||
2425 | *** Support for `find-function' and similar utilities, through the addition | |
2426 | of filename support to generated symbols. | |
2427 | ||
f938eda9 | 2428 | ** Floating point functions now always return special values like NaN, |
823b2fb6 | 2429 | instead of signaling errors, if given invalid args; e.g., (log -1.0). |
f938eda9 CY |
2430 | Previously, they returned NaNs on some platforms but signaled errors |
2431 | on others. The affected functions are acos, asin, tan, exp, expt, | |
2432 | log, log10, sqrt, and mod. | |
2433 | ||
6bc66c10 | 2434 | ** New fringe bitmap `exclamation-mark'. |
f938eda9 | 2435 | |
6bc66c10 GM |
2436 | ** Miscellaneous changes to special forms and macros |
2437 | ||
2438 | *** `defun' and `defmacro' are now macros rather than special forms. | |
2439 | ||
2440 | *** `kbd' is now a function rather than a macro. | |
2441 | ||
2442 | ** Miscellaneous new functions | |
2443 | ||
b29daf07 GM |
2444 | *** `set-temporary-overlay-map' sets up a temporary keymap that |
2445 | takes precedence over most other maps for a short while (normally one key). | |
f938eda9 | 2446 | |
847a0561 | 2447 | *** `autoloadp' tests if its argument is an autoloaded object. |
2f940384 | 2448 | |
847a0561 | 2449 | *** `autoload-do-load' performs the autoloading operation. |
2f940384 | 2450 | |
f938eda9 | 2451 | *** `buffer-narrowed-p' tests if the buffer is narrowed. |
2f940384 | 2452 | |
f938eda9 | 2453 | *** `file-name-base' returns a file name sans directory and extension. |
2f940384 | 2454 | |
f938eda9 | 2455 | *** `function-get' fetches a function property, following aliases. |
c990426a | 2456 | |
f938eda9 | 2457 | *** `posnp' tests if an object is a `posn'. |
f938eda9 | 2458 | |
f938eda9 | 2459 | *** `system-users' returns the user names on the system. |
547d6865 | 2460 | |
f938eda9 | 2461 | *** `system-groups' returns the group names on the system. |
f938eda9 | 2462 | |
f938eda9 | 2463 | *** `tty-top-frame' returns the topmost frame of a text terminal. |
c990426a | 2464 | |
f938eda9 | 2465 | ** The following functions and variables are obsolete: |
847a0561 | 2466 | *** `automount-dir-prefix' (use `directory-abbrev-alist') |
f938eda9 | 2467 | *** `buffer-has-markers-at' |
1a9c6830 | 2468 | *** `macro-declaration-function' (use `macro-declarations-alist') |
847a0561 | 2469 | *** `window-system-version' (provides no useful information) |
93cacb6d | 2470 | *** `dired-pop-to-buffer' (use `dired-mark-pop-up') |
0e2ae83d | 2471 | *** `query-replace-interactive' |
49238e7f | 2472 | *** `font-list-limit' (has had no effect since Emacs < 23) |

93e0bed6 | 2475 | * Changes in Emacs 24.3 on Non-Free Operating Systems |
9078ead6 | 2476 | |
4e98ad15 | 2477 | ** Cygwin builds can use the native MS Windows user interface. |
823b2fb6 | 2478 | Pass `--with-w32' to configure. The default remains the X11 interface. |
53a63be6 | 2479 | |
1a9c6830 | 2480 | ** Two new functions are available in Cygwin builds: |
6e9f7997 DC |
2481 | `cygwin-convert-file-name-from-windows' and |
2482 | `cygwin-convert-file-name-to-windows'. These functions allow Lisp | |
2483 | code to access the Cygwin file-name mapping machinery to convert | |
2484 | between Cygwin and Windows-native file and directory names. | |
de6e3a60 | 2485 | |
4e98ad15 | 2486 | ** When invoked with the -nw switch to run on the Windows text-mode terminal, |
1ab0c851 | 2487 | Emacs now supports `mouse-highlight', help-echo (in the echo area), and |
4e98ad15 GM |
2488 | `mouse-autoselect-window'. |
2489 | ||
1a9c6830 | 2490 | ** On MS Windows Vista and later Emacs now supports symbolic links. |
4e98ad15 | 2491 | |
823b2fb6 | 2492 | ** On MS Windows, you can pass `--without-libxml2' to configure.bat to omit |
4e98ad15 GM |
2493 | support for libxml2, even if its presence is detected. |
2494 | ||
4e98ad15 GM |
2495 | ** On Mac OS X, the Nextstep port requires OS X 10.4 or later. |

31fd3586 GM |
2508 | ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
2509 | to configure. Note that other libraries used by Emacs, RSVG and GConf, | |
2510 | also depend on Gtk+. You can disable them with --without-rsvg and | |
2511 | --without-gconf. | |
338648ad | 2512 | |
31fd3586 GM |
2513 | ** Emacs can be compiled with GnuTLS support. |
2514 | This happens by default if a suitably recent version of the library is | |
2515 | found at build time. To prevent this, use the configure option | |
2516 | `--without-gnutls'. See below for GnuTLS features. | |
338648ad | 2517 | |
31fd3586 GM |
2518 | ** Emacs can be compiled with SELinux support. |
2519 | This happens by default if a suitably recent version of the library is | |

2526 | `--without-imagemagick'. See below for ImageMagick features. | |
c1f10868 | 2527 | This feature is not available for the Nextstep or MS ports. |

2529 | ** Emacs can be compiled with libxml2 support. |
2530 | This happens by default if a suitably recent version of the library is | |
2531 | found at build time. To prevent this, use the configure option | |
2532 | `--without-xml2'. See below for libxml2 features. | |

2534 | ** By default, the installed Info and man pages are compressed. |
2535 | You can disable this by configuring --without-compress-info. | |
2536 | ||
7d301ae6 | 2537 | ** New configure option --with-wide-int. |
81eafe29 | 2538 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. |
0a768890 PE |
2539 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB |
2540 | to about 2 GiB. | |
81eafe29 | 2541 | |
7d301ae6 | 2542 | ** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost. |
31fd3586 GM |
2543 | These provide no new functionality, they just remove the need to edit |
2544 | lib-src/Makefile by hand in order to use the associated features. | |
2545 | ||
7d301ae6 | 2546 | ** New configure option --enable-use-lisp-union-type. |
31fd3586 GM |
2547 | This is only useful for Emacs developers to debug certain types of bugs. |
2548 | This is not a new feature; only the configure flag is new. | |
041d709f CY |
2549 | |
2550 | ** The standalone programs digest-doc and sorted-doc are removed. | |
2551 | Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'. | |
2552 | ||
041d709f CY |
2553 | ** The standalone program `fakemail' is removed. |
2554 | If you need it, feedmail.el provides a superset of the functionality. | |

eb199145 | 2557 | * Startup Changes in Emacs 24.1 |
4a263588 | 2558 | |
198a7a97 | 2559 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte |
adbf62ff GM |
2560 | command line arguments, and the EMACS_UNIBYTE environment variable, no |
2561 | longer have any effect. (They were declared obsolete in Emacs 23.) | |
198a7a97 | 2562 | |
66b7b0fe | 2563 | ** New command line option `--no-site-lisp' removes site-lisp directories |
1b5e5b0c GM |
2564 | from load-path. -Q now implies this. This option does not affect the |
2565 | EMACSLOADPATH environment variable (and hence has no effect for | |
c8d59ba3 | 2566 | Nextstep builds). |

eb199145 | 2569 | * Changes in Emacs 24.1 |
7841339b | 2570 | |
a2a25d24 | 2571 | ** Completion |
fdeb32ec | 2572 | |
dfdb4cad CY |
2573 | *** Many packages now use the `completion-at-point' command, |
2574 | rather than implementing separate completion commands. | |
2575 | ||
de0bde62 | 2576 | *** `completion-at-point' now handles tags and semantic completion. |
dfdb4cad | 2577 | |
a2a25d24 SM |
2578 | *** Completion in a non-minibuffer now tries to detect the end of completion |
2579 | and pops down the *Completions* buffer accordingly. | |
dfdb4cad CY |
2580 | |
2581 | *** New option `completion-cycle-threshold' allows completion cycling. | |
2582 | ||
2583 | *** New option `completion-category-overrides' for overriding the | |
2c719188 | 2584 | default completion style in certain circumstances. |
dfdb4cad | 2585 | |
a2a25d24 | 2586 | *** New completion style `substring'. |
dfdb4cad CY |
2587 | |
2588 | *** Completion of buffer names uses `substring' completion by default. | |
2589 | ||
2590 | *** The option `widget-complete-field' has been removed. | |
620c53a6 | 2591 | |
6870aaef | 2592 | ** Mail changes |
dfdb4cad | 2593 | |
7d301ae6 CY |
2594 | *** The first time you try sending mail, Emacs asks for a mail method. |
2595 | This is implemented by a new default for `send-mail-function', which | |
2596 | is `sendmail-query-once'. This offers to use the smtpmail package, or | |
2597 | to use the old defaults relying on external mail facilities | |
2598 | (`sendmail-send-it' on GNU/Linux and other Unix-like systems, and | |
2599 | `mailclient-send-it' on Windows). | |
dfdb4cad | 2600 | |
e78e7e48 CY |
2601 | *** Typing `C-c m' in the buffer made by `M-x report-emacs-bug' |
2602 | transfers the report to your desktop's preferred mail client, if there | |
2603 | is one. This uses either the "xdg-email" utility, or Mac OS's "open" | |
2604 | command. | |
dfdb4cad | 2605 | |
7d301ae6 CY |
2606 | *** See Changes in Specialized Modes and Packages for SMTPmail changes |
2607 | and Mail mode changes | |
3f88cd72 | 2608 | |
041d709f | 2609 | ** Emacs server and client changes |
dfdb4cad | 2610 | |
7d301ae6 | 2611 | *** New option `server-port' specifies the port for TCP Emacs servers. |
dfdb4cad | 2612 | |
041d709f | 2613 | *** New emacsclient argument -q/--quiet suppresses some status messages. |
dfdb4cad | 2614 | |
7d301ae6 CY |
2615 | *** New emacsclient argument --frame-parameters specifies the frame |
2616 | parameters of any newly-created graphical frame. | |
dfdb4cad CY |
2617 | |
2618 | *** If emacsclient shuts down due to Emacs signaling an error, | |
2619 | its exit status is 1. | |
2620 | ||
041d709f CY |
2621 | *** New emacsclient argument --parent-id ID. |
2622 | This opens a client frame in parent X window ID, via XEmbed, similar | |
2623 | to the --parent-id argument to Emacs. | |
2624 | ||
d0ce9f8c MB |
2625 | ** Internationalization changes |
2626 | ||
d0ce9f8c | 2627 | *** Emacs now supports display and editing of bidirectional text. |
7d301ae6 CY |
2628 | Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are |
2629 | displayed in the correct visual order as expected by users of those | |
dfdb4cad CY |
2630 | scripts. The display reordering is a "full bidirectionality" class |
2631 | implementation of the Unicode Bidirectional Algorithm (UBA). Buffers | |
2632 | with no RTL text should look exactly the same as before. | |
f4b6ba46 | 2633 | |
041d709f | 2634 | **** New buffer-local variable `bidi-display-reordering'. |
7d301ae6 | 2635 | To disable display reordering in a buffer, change this to nil. |
d20e1419 | 2636 | |
041d709f CY |
2637 | **** New buffer-local variable `bidi-paragraph-direction'. |
2638 | If nil (the default), Emacs determines the base direction of each | |
dfdb4cad CY |
2639 | paragraph from its text, as specified by the UBA. Setting the value |
2640 | to `right-to-left' or `left-to-right' forces a base direction on each | |
2641 | paragraph. | |
f4b6ba46 | 2642 | |
7d301ae6 CY |
2643 | Paragraphs with right-to-left base direction are displayed starting at |
2644 | the right window edge. | |
f1816485 | 2645 | |
dfdb4cad CY |
2646 | *** Enhanced support for characters with no glyphs in available fonts, |
2647 | or, on text terminals, characters that cannot be encoded by the | |
2648 | terminal coding system. The new option `glyphless-char-display-control' | |
2649 | specifies how to display them: as a hexadecimal code in a box, a thin | |
2650 | 1-pixel space, an empty box, etc. | |
d0ce9f8c | 2651 | |
9702b7a1 GM |
2652 | *** New input methods for Farsi and Bulgarian |
2653 | (farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic). | |
041d709f | 2654 | |
939db9ac CY |
2655 | *** `nobreak-char-display' now also highlights Unicode hyphen chars |
2656 | (U+2010 and U+2011). | |
2657 | ||
7d301ae6 | 2658 | *** New Hebrew translation of the Emacs Tutorial. |
31fd3586 GM |
2659 | Type `C-u C-h t' to choose it in case your language setup doesn't |
2660 | automatically select it. | |
2661 | ||
7d301ae6 CY |
2662 | ** An Emacs Lisp package manager is now included. |
2663 | This is a convenient way to download and install additional packages, | |
2664 | from a package repository at http://elpa.gnu.org. | |
dfdb4cad | 2665 | |
7d301ae6 CY |
2666 | *** M-x list-packages shows a list of packages, which can be |
2667 | selected for installation. | |
dfdb4cad | 2668 | |
7d301ae6 | 2669 | *** New command `describe-package', bound to `C-h P'. |
dfdb4cad | 2670 | |
7d301ae6 CY |
2671 | *** By default, all installed packages are loaded automatically when |
2672 | Emacs starts up. To disable this, set `package-enable-at-startup' to | |
2673 | nil. To specify the packages to load, customize `package-load-list'. | |
16a91140 | 2674 | |
dfdb4cad CY |
2675 | ** Custom theme changes |
2676 | ||
7d301ae6 CY |
2677 | *** New command `M-x customize-themes', which provides a convenient |
2678 | interface for enabling and disabling Custom themes. | |
dfdb4cad | 2679 | |
7d301ae6 | 2680 | *** New option `custom-theme-load-path' is the load path for themes. |
dfdb4cad CY |
2681 | Emacs no longer looks for Custom themes in `load-path'. The default |
2682 | value of `custom-theme-load-path' says to look for themes in | |
2683 | `custom-theme-directory', followed by a subdirectory of | |
2684 | `data-directory' named "themes/", which contains a small selection of | |
2685 | built-in Custom themes. | |
2686 | ||
7d301ae6 CY |
2687 | *** New option `custom-safe-themes' records known-safe theme files. |
2688 | If a theme is not in this list, Emacs queries before loading it, and | |
2689 | offers to save the theme to `custom-safe-themes' automatically. By | |
2690 | default, all themes included in Emacs are treated as safe. | |
b7d65a5f | 2691 | |
7d301ae6 | 2692 | ** Improved GTK integration |
dfdb4cad | 2693 | |
7d301ae6 | 2694 | *** GTK scroll-bars are now placed on the right by default. |
dfdb4cad CY |
2695 | The function `set-scroll-bar-mode' can change this. |
2696 | ||
7d301ae6 | 2697 | *** GTK tool bars can have just text, just images or images and text. |
dfdb4cad CY |
2698 | Customize `tool-bar-style' to choose the style. On a Gnome desktop, |
2699 | the default is taken from desktop settings. | |
2700 | ||
2701 | *** GTK tool bars can be placed on any edge of the frame. | |
7d301ae6 CY |
2702 | The frame-parameter tool-bar-position controls this. It takes the |
2703 | values top, left, right or bottom. The Options => Show/Hide menu has | |
2704 | entries for this. | |
dfdb4cad | 2705 | |
7d301ae6 CY |
2706 | *** The default colors for selected text (the `region' face) are taken |
2707 | from the GTK theme when Emacs is built with GTK. | |
dfdb4cad | 2708 | |
7d301ae6 CY |
2709 | *** Emacs uses GTK tooltips by default if built with GTK. |
2710 | You can disable this by changing `x-gtk-use-system-tooltips' to nil. | |
a5bee597 | 2711 | |
dfdb4cad CY |
2712 | ** Graphical interface changes |
2713 | ||
2714 | *** On graphical displays, the mode-line no longer ends in dashes. | |
2715 | Also, the first dash (which does not indicate anything) is just | |
2716 | displayed as a space. | |
2717 | ||
2718 | *** `menu-bar-select-buffer-function' lets you choose another operation | |
2719 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. | |
2720 | ||
2721 | *** Lucid menus and dialogs can display antialiased fonts if Emacs is | |
2722 | built with Xft. These fonts can be set via X resources, for example: | |
2723 | Emacs.pane.menubar.font: Courier-12 | |
2724 | ||
7d301ae6 | 2725 | ** Exiting changes |
dfdb4cad | 2726 | |
7d301ae6 | 2727 | *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP, |
dfdb4cad CY |
2728 | or if it receives a SIGINT signal in batch mode. |
2729 | ||
7d301ae6 CY |
2730 | *** `kill-emacs-hook' is now also run in batch mode. |
2731 | Third-party code which adds to `kill-emacs-hook' should check if they | |
2732 | do the right thing in batch mode. | |
9c524fcb | 2733 | |
041d709f | 2734 | ** Scrolling changes |
dfdb4cad | 2735 | |
041d709f | 2736 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' |
0a19a6f8 | 2737 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
7d301ae6 | 2738 | of buffer at first key-press (instead they move to top/bottom of buffer) |
550f41cd | 2739 | when `scroll-error-top-bottom' is non-nil. |
dfdb4cad CY |
2740 | |
2741 | *** New option `scroll-error-top-bottom' (see above). | |
2742 | ||
041d709f | 2743 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' |
5a97d2da | 2744 | scroll a line instead of full screen. |
dfdb4cad | 2745 | |
041d709f | 2746 | *** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 2747 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
dfdb4cad | 2748 | |
041d709f | 2749 | *** If you customize `scroll-conservatively' to a value greater than 100, |
d0f69533 EZ |
2750 | Emacs will never recenter point in the window when it scrolls due to |
2751 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | |
2752 | Previously, you needed to use `most-positive-fixnum' as the value of | |
2753 | `scroll-conservatively' to achieve the same effect. | |
dfdb4cad | 2754 | |
7d301ae6 | 2755 | *** "Aggressive" scrolling now honors the scroll margins. |
d0f69533 EZ |
2756 | If you customize `scroll-up-aggressively' or |
2757 | `scroll-down-aggressively' and move point off the window, Emacs now | |
2758 | scrolls the window so as to avoid positioning point inside the scroll | |
2759 | margin. | |
2760 | ||
7d301ae6 CY |
2761 | ** Basic SELinux support has been added. |
2762 | This requires Emacs to be linked with libselinux at build time. | |
f1a5d776 | 2763 | |
dfdb4cad CY |
2764 | *** Emacs preserves the SELinux file context when backing up. |
2765 | Also, the function `copy-file' has an extra optional argument for | |
2766 | preserving SELinux context, and the return value of `backup-buffer' | |
2767 | now includes the SELinux context. | |
f0bf7c8e | 2768 | |
dfdb4cad | 2769 | *** New functions `file-selinux-context' and `set-file-selinux-context' |
7d301ae6 | 2770 | get and set the SELinux context of a file. |
44198b6e | 2771 | |
7d301ae6 | 2772 | ** Trash changes |
dfdb4cad | 2773 | |
7d301ae6 CY |
2774 | *** `delete-by-moving-to-trash' now only affects commands that specify |
2775 | trashing. This avoids inadvertently trashing temporary files. | |
dfdb4cad | 2776 | |
7d301ae6 CY |
2777 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
2778 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
278f6845 | 2779 | |
041d709f | 2780 | ** File- and directory-local variable changes |
dfdb4cad | 2781 | |
041d709f CY |
2782 | *** You can stop directory local vars from applying to subdirectories. |
2783 | Add an element (subdirs . nil) to the alist portion of any variables | |
2784 | settings to indicate that the section should not apply to | |
2785 | subdirectories. | |
dfdb4cad | 2786 | |
041d709f CY |
2787 | *** Directory local variables can apply to some file-less buffers. |
2788 | Affected modes include dired, vc-dir, and log-edit. For example, | |
2789 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will | |
2790 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call | |
2791 | `hack-dir-local-variables-non-file-buffer' to support this. | |
dfdb4cad | 2792 | |
041d709f CY |
2793 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. |
2794 | Instead, use "eval: (minor-mode 1)". | |
c136e5cd | 2795 | |
7b447e9b GM |
2796 | *** The variable `inhibit-first-line-modes-regexps' has been renamed |
2797 | to `inhibit-local-variables-regexps'. As the name suggests, it now | |
dfdb4cad CY |
2798 | applies to ALL file local variables, not just -*- lines. The |
2799 | associated `inhibit-first-line-modes-suffixes' has been renamed in the | |
2800 | corresponding way. | |
5d907d6c | 2801 | |
0a2132ba CY |
2802 | ** Window changes |
2803 | ||
91b65361 CY |
2804 | *** The `quit-window' command now restores the last buffer displayed |
2805 | in the quitted window. | |
2806 | ||
0a2132ba CY |
2807 | *** Resizing an Emacs frame now preserves proportional window sizes, |
2808 | modulo restrictions like window minimum sizes and fixed-size windows. | |
2809 | ||
2810 | *** The behavior of `display-buffer' is now customizable in detail. | |
dfdb4cad | 2811 | |
0a2132ba CY |
2812 | **** New option `display-buffer-base-action' specifies a list of |
2813 | user-determined display "actions" (functions and optional arguments | |
2814 | for choosing the displaying window). | |
2815 | ||
2816 | This takes precedence over the default display action, which is | |
2817 | specified by `display-buffer-fallback-action'. | |
2818 | ||
2819 | **** New option `display-buffer-alist' maps buffer name regexps to | |
2820 | display actions, taking precedence over `display-buffer-base-action'. | |
2821 | ||
a0c2d0ae MR |
2822 | *** New option `window-combination-limit'. |
2823 | The new option `window-combination-limit' allows to return the space | |
2824 | obtained for resizing or creating a window more reliably to the window | |
2825 | from which such space was obtained. | |
0a2132ba | 2826 | |
a0c2d0ae MR |
2827 | *** New option `window-combination-resize'. |
2828 | The new option `window-combination-resize' allows to split a window that | |
2829 | otherwise cannot be split because it's too small by stealing space from | |
2830 | other windows in the same combination. Subsequent resizing or deletion | |
2831 | of the window will resize all windows in the same combination as well. | |
0a2132ba | 2832 | |
91b65361 CY |
2833 | *** New option `frame-auto-hide-function' lets you choose between |
2834 | iconifying or deleting a frame when burying a buffer in a dedicated | |
2835 | frame, or quitting a window showing a buffer in a frame of its own. | |
2836 | ||
0a2132ba | 2837 | *** New commands `maximize-window' and `minimize-window'. |
53964682 | 2838 | These maximize and minimize the size of a window within its frame. |
0a2132ba | 2839 | |
0a2132ba CY |
2840 | *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'. |
2841 | These functions allow to navigate through the live buffers that have | |
2842 | been shown in a specific window. | |
2843 | ||
7d301ae6 | 2844 | ** Minibuffer changes |
dfdb4cad | 2845 | |
7d301ae6 | 2846 | *** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. |
104dc9c6 GM |
2847 | This is handy for minibuffer-only frames, and is also used for the feature |
2848 | where mouse-1 pops up *Messages*"', which can now easily be changed. | |
041d709f | 2849 | |
7d301ae6 | 2850 | *** Minibuffers set `truncate-lines' to nil. |
f66eca26 | 2851 | If you want to change the value to something else, you could use |
7d301ae6 CY |
2852 | for example `minibuffer-setup-hook'. |
2853 | ||
7d301ae6 CY |
2854 | ** `auto-mode-case-fold' is now enabled by default. |
2855 | ||
7d301ae6 | 2856 | ** `backup-by-copying-when-mismatch' now defaults to t. |
f66eca26 | 2857 | |
dfdb4cad CY |
2858 | ** New basic faces `error', `warning', `success'. |
2859 | These are used to highlight text indicating failure, caution or | |
2860 | successful operation. | |
2861 | ||
2862 | ** New option `list-colors-sort' defines the color sort order | |
2863 | for `list-colors-display'. | |
2864 | ||
2865 | ** The variable `focus-follows-mouse' now always defaults to nil. | |

892777ba | 2870 | ** Search changes |
dfdb4cad CY |
2871 | |
2872 | *** C-y in Isearch is now bound to `isearch-yank-kill', instead of | |
2873 | `isearch-yank-line'. | |
2874 | ||
2875 | *** M-y in Isearch is now bound to `isearch-yank-pop', instead of | |
2876 | `isearch-yank-kill'. | |
2877 | ||
2878 | *** M-s C-e in Isearch is now bound to `isearch-yank-line'. | |
2879 | ||
b2b0776e | 2880 | ** New commands `count-words-region' and `count-words'. |
dfdb4cad | 2881 | |
10607bea CY |
2882 | *** M-= is bound to `count-words-region', not `count-lines-region'. |
2883 | The `count-words-region' command, when called interactively, reports | |
2884 | the number of lines, words, and characters in the region. It is a | |
2885 | superset of the old `count-lines-region', which is now an obsolete | |
2886 | alias for it. | |
ea4f7750 | 2887 | |
ec9da840 | 2888 | ** The command `just-one-space' (M-SPC), if given a negative argument, |
1c708c1a CY |
2889 | also deletes newlines around point. |
2890 | ||
b9229673 | 2891 | ** Deletion changes |
dfdb4cad | 2892 | |
b9229673 | 2893 | *** New option `delete-active-region'. |
ddb54206 | 2894 | If non-nil, [delete] and DEL delete the region if it is active and no |
dfdb4cad | 2895 | prefix argument is given. If set to `kill', those commands kill |
ddb54206 | 2896 | instead. |
dfdb4cad | 2897 | |
59ee0542 | 2898 | *** New command `delete-forward-char', bound to [delete]. |
42d9cffa CY |
2899 | This is meant for interactive use, and obeys `delete-active-region'. |
2900 | The command `delete-char' does not obey `delete-active-region'. | |
dfdb4cad | 2901 | |
b9229673 CY |
2902 | *** `delete-backward-char' is now a Lisp function. |
2903 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
7d301ae6 CY |
2904 | However, the byte compiler now warns if it is called from Lisp; Lisp |
2905 | callers should use delete-char with a negative argument instead. | |
dfdb4cad | 2906 | |
b9229673 CY |
2907 | *** The option `mouse-region-delete-keys' has been deleted. |
2908 | ||
f9d71b42 CY |
2909 | ** Selection changes. |
2910 | ||
7d301ae6 CY |
2911 | The default handling of clipboard and primary selections has been |
2912 | changed to conform with modern X applications. In short, most | |
2913 | commands for killing and yanking text now use the clipboard, while | |
2914 | mouse commands use the primary selection. | |
b1ab31ae CY |
2915 | |
2916 | In the following, we provide a list of these changes, followed by a | |
2917 | list of steps to get the old behavior back if you prefer that. | |
2918 | ||
b1ab31ae CY |
2919 | *** `select-active-regions' now defaults to t. |
2920 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
963578d3 | 2921 | the kill ring. The selected text is put in the primary selection, if |
b1ab31ae CY |
2922 | the system possesses a separate primary selection facility (e.g. X). |
2923 | ||
2924 | **** `select-active-regions' also accepts a new value, `only'. | |
2925 | This means to only set the primary selection for temporarily active | |
2926 | regions (usually made by mouse-dragging or shift-selection); | |
2927 | "ordinary" active regions, such as those made with C-SPC followed by | |
2928 | point motion, do not alter the primary selection. | |
2929 | ||
963578d3 CY |
2930 | **** `mouse-drag-copy-region' now defaults to nil. |
2931 | ||
b1ab31ae CY |
2932 | *** mouse-2 is now bound to `mouse-yank-primary'. |
2933 | This pastes from the primary selection, ignoring the kill-ring. | |
2934 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
dfdb4cad | 2935 | |
b1ab31ae | 2936 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
dfdb4cad | 2937 | |
b1ab31ae CY |
2938 | *** `x-select-enable-primary' now defaults to nil. |
2939 | Thus, commands that kill text or copy it to the kill-ring (such as | |
2940 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
2941 | ||
2942 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now | |
dfdb4cad | 2943 | exactly equivalent to M-w, C-w, and C-y respectively. |
b1ab31ae CY |
2944 | |
2945 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already | |
2946 | non-nil by default, as Windows does not support the primary selection | |
2947 | between applications. | |
2948 | ||
2949 | *** To return to the previous behavior, do the following: | |
dfdb4cad | 2950 | |
104c2fe9 | 2951 | **** Change `select-active-regions' to nil. |
b1ab31ae CY |
2952 | **** Change `mouse-drag-copy-region' to t. |
2953 | **** Change `x-select-enable-primary' to t (on X only). | |
2954 | **** Change `x-select-enable-clipboard' to nil. | |
2955 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 2956 | |
084e6df3 | 2957 | *** Support for X cut buffers has been removed. |
dfdb4cad | 2958 | |
3fd50d5c CY |
2959 | *** X clipboard managers are now supported. |
2960 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. | |
4b80f674 | 2961 | |
dfdb4cad CY |
2962 | ** New command `C-x r N' (`rectangle-number-lines') numbers the lines |
2963 | in the current rectangle. With a prefix argument, this prompts for a | |
2964 | number to count from and for a format string. | |
99f053cf | 2965 | |
7d301ae6 | 2966 | ** `redisplay-dont-pause' now defaults to t. |
6bf7006f EZ |
2967 | This makes Emacs feel more responsive to editing commands that arrive |
2968 | at high rate, e.g. if you lean on some key, because stopping redisplay | |
2969 | in the middle (when this variable is nil) forces more expensive | |
2970 | updates later on, and Emacs appears to be unable to keep up. | |
2971 | ||
e70b5064 CY |
2972 | ** The behavior of <TAB> for active regions in Text mode has changed. |
2973 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | |
2974 | when the region is active causes Emacs to indent all the lines in the | |
2975 | region, aligning them with the line previous to the first line in the | |
2976 | region (or with the left margin if there is no previous line). | |
2977 | ||
dfdb4cad CY |
2978 | ** When `occur' is called with a prefix argument, matching strings are |
2979 | collected into the `*Occur*' buffer without line numbers. If there | |
2980 | are parenthesized subexpressions in the specified regexp, `occur' | |
2981 | reads replacement text that may contain \\& and \\N whose convention | |
2982 | follows `replace-match'. | |
2983 | ||
9bae34bf | 2984 | \f |
eb199145 | 2985 | * Changes in Specialized Modes and Packages in Emacs 24.1 |
efeb796b | 2986 | |
041d709f | 2987 | ** Archive Mode has basic support for browsing and updating 7z archives. |
d76674bb | 2988 | |
b7c3692a | 2989 | ** BibTeX mode |
dfdb4cad | 2990 | |
2de69e00 | 2991 | *** BibTeX mode now supports biblatex. |
7d301ae6 CY |
2992 | Use the variable `bibtex-dialect' to select different BibTeX dialects. |
2993 | `bibtex-entry-field-alist' is now an obsolete alias for | |
2994 | `bibtex-BibTeX-entry-alist'. | |
2995 | ||
dfdb4cad CY |
2996 | *** New command `bibtex-search-entries', bound to C-c C-a. |
2997 | ||
b7c3692a | 2998 | *** New `bibtex-entry-format' option `sort-fields', disabled by default. |
dfdb4cad | 2999 | |
022fe7ce RW |
3000 | *** New variable `bibtex-search-entry-globally'. |
3001 | ||
7d301ae6 | 3002 | ** Browse-url |
dfdb4cad | 3003 | |
7d301ae6 | 3004 | *** New option `browse-url-mailto-function' specifies how to handle "mailto:"s. |
dfdb4cad | 3005 | |
7d301ae6 CY |
3006 | *** The default browser used by the package is now the "xdg-open" program, |
3007 | on platforms that support it. This calls your desktop's preferred browser. | |
3008 | ||
86e100a6 GM |
3009 | ** Calc |
3010 | ||
3011 | *** Support for musical notes. | |
3012 | ||
3013 | *** Support for logarithmic units. | |
3014 | ||
3015 | *** No longer uses the tex prefix for TeX specific unit names when | |
3016 | using TeX or LaTeX mode. | |
3017 | ||
3018 | *** New option to highlight selections using faces. | |
3019 | ||
3020 | *** `calc-histogram' has the option of using a vector to determine the bins. | |
3021 | ||
3022 | *** New "O" option prefix. | |
3023 | ||
3024 | *** Use the "O" prefix to "d r" (`calc-radix') to turn on twos-complement mode. | |
3025 | ||
cf16af42 GM |
3026 | ** Calendar, Diary, and Appt |
3027 | ||
7d301ae6 | 3028 | *** Diary entries can contain non-printing "comments". |
548d0a63 GM |
3029 | See the variable `diary-comment-start'. |
3030 | ||
5006e634 GM |
3031 | *** Appointments can specify their individual warning times. |
3032 | See the variable `appt-warning-time-regexp'. | |
3033 | ||
0a2bb1a9 GM |
3034 | *** The function specified by `appt-disp-window-function' may be passed |
3035 | lists of arguments if multiple appointments are due at similar times. | |
3036 | If you are using a custom function for this, you should update it. | |
3037 | ||
7454f200 GM |
3038 | *** New function `diary-hebrew-birthday'. |
3039 | ||
e565dd37 GM |
3040 | *** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array' |
3041 | may no longer be nil, but must all be strings. | |
3042 | ||
7d301ae6 CY |
3043 | *** The obsolete (since Emacs 22.1) method of enabling the appt |
3044 | package by adding `appt-make-list' to `diary-hook' has been removed. | |
3045 | Use `appt-activate' instead. | |
cf16af42 | 3046 | |
cf16af42 GM |
3047 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: |
3048 | appt-issue-message (use the function appt-activate) | |
3049 | appt-visible/appt-msg-window (use the variable appt-display-format) | |
3050 | ||
cf16af42 GM |
3051 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: |
3052 | view-diary-entries, list-diary-entries, show-all-diary-entries | |
3053 | ||
551b046f | 3054 | ** CC Mode |
dfdb4cad | 3055 | |
551b046f | 3056 | *** New feature to "guess" the style in an existing buffer. |
7d301ae6 | 3057 | The main entry point is M-x c-guess. |
041d709f | 3058 | |
551b046f AM |
3059 | *** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang). |
3060 | ||
dfdb4cad | 3061 | *** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes. |
551b046f AM |
3062 | Thus C-M-a will, by default, go to the beginning of the immediate function, |
3063 | not the top level. | |
3064 | ||
dfdb4cad | 3065 | *** "Macros with semicolons" can be registered for correct indentation. |
551b046f AM |
3066 | Where such a macro ends a line (no semicolon) the next statement is no longer |
3067 | parsed as a statement continuation. | |
3068 | ||
dfdb4cad | 3069 | ** Comint and modes derived from it use the standard completion code. |
041d709f CY |
3070 | |
3071 | ** Compilation mode | |
dfdb4cad | 3072 | |
7d301ae6 | 3073 | *** Compilation mode can be used without Font Lock mode. |
041d709f CY |
3074 | `compilation-parse-errors-function' is now obsolete. |
3075 | ||
dfdb4cad | 3076 | *** New variable `compilation-filter-start', which is bound while |
7d301ae6 CY |
3077 | `compilation-filter-hook' runs. It records the start position of the |
3078 | text inserted by `compilation-filter'. | |
041d709f | 3079 | |
47a6a35f GM |
3080 | *** `compilation-error-screen-columns' and `compilation-first-column' |
3081 | are obeyed in the editing buffer. So programming language modes can | |
7d301ae6 CY |
3082 | set them, whereas previously only the value in the *Compilation* |
3083 | buffer was used. | |
1dce7193 | 3084 | |
52834b6b CY |
3085 | ** Customize |
3086 | ||
3087 | *** Customize buffers now contain a search field. | |
3088 | The search is performed using `customize-apropos'. | |
7d301ae6 | 3089 | To turn off the search field, set `custom-search-field' to nil. |
52834b6b | 3090 | |
8d5dd370 | 3091 | *** Options in customize group buffers start out hidden if not customized. |
52834b6b CY |
3092 | Use the arrow to the left of the option name to toggle visibility. |
3093 | ||
3094 | *** custom-buffer-sort-alphabetically now defaults to t. | |
3095 | ||
3096 | *** The color widget now has a "Choose" button, which allows you to | |
7d301ae6 | 3097 | choose a color via `list-colors-display'. |
52834b6b | 3098 | |
041d709f CY |
3099 | ** D-Bus |
3100 | ||
5da3be7f GM |
3101 | *** It is now possible to access buses other than the default system |
3102 | or session bus. | |
041d709f | 3103 | |
7d301ae6 | 3104 | *** The `dbus-register-method' and `dbus-register-property' functions |
5da3be7f | 3105 | optionally do not register names. |
041d709f | 3106 | |
7d301ae6 | 3107 | *** The new function `dbus-register-service' registers a known service |
dfdb4cad | 3108 | name on a D-Bus without also registering a property or a method. |
041d709f | 3109 | |
f5d6548a | 3110 | ** Dired-x |
425a25f1 | 3111 | |
7d301ae6 CY |
3112 | *** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'), |
3113 | if called with a prefix argument, read a file name from the minibuffer | |
3114 | instead of using the current buffer. | |
f5d6548a | 3115 | |
7d301ae6 | 3116 | *** The "dired local variables" feature of Dired-x is obsolete. |
817b48a7 | 3117 | The standard directory local variables feature replaces it. |
8117868f | 3118 | |
041d709f | 3119 | ** ERC changes |
7492acc9 | 3120 | |
c4077254 GM |
3121 | *** New options `erc-autojoin-timing' and `erc-autojoin-delay', |
3122 | controlling attempts to autojoin a channel. | |
041d709f CY |
3123 | |
3124 | *** New variable `erc-coding-system-precedence': If we use `undecided' | |
3125 | as the server coding system, this variable will then be consulted. | |
3126 | The default is to decode strings that can be decoded as utf-8 as | |
3127 | utf-8, and do the normal `undecided' decoding for the rest. | |
7492acc9 | 3128 | |
041d709f | 3129 | ** Eshell changes |
7492acc9 | 3130 | |
05f77e38 GM |
3131 | *** The default value of `eshell-directory-name' has changed |
3132 | to be an "eshell" directory in `user-emacs-directory'. | |
3133 | The old "~/.eshell/" directory is still used if it exists, though. | |
041d709f CY |
3134 | |
3135 | ** gdb-mi | |
dfdb4cad CY |
3136 | |
3137 | *** The M-x gdb command now uses the GDB Machine Interface protocol. | |
05f77e38 GM |
3138 | It now supports multithread non-stop debugging and simultaneous |
3139 | debugging of several threads. | |
7492acc9 | 3140 | |
18af70d0 CY |
3141 | ** Image mode |
3142 | ||
05f77e38 GM |
3143 | *** RET (`image-toggle-animation') toggles animation, if applicable. |
3144 | Animation plays once, unless the option `image-animate-loop' is non-nil. | |
18af70d0 | 3145 | |
041d709f | 3146 | ** Info |
723ee192 | 3147 | |
7d301ae6 | 3148 | *** New command M-x info-display-manual displays a named Info manual. |
2ebc3b94 GM |
3149 | If that manual is already visited in some Info buffer, it displays |
3150 | that buffer. (This is handy if you have many manuals in many *info* | |
3151 | buffers, and don't remember the name of the buffer visiting the manual | |
3152 | you want to consult.) Otherwise, it loads and displays the manual. | |
691cf4a0 | 3153 | |
24ea72d3 EZ |
3154 | *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'. |
3155 | This is for compatibility with the stand-alone Info reader program, | |
3156 | and also because `Info-edit' is a rarely used command that is disabled | |
3157 | by default. | |
3158 | ||
7d301ae6 | 3159 | ** Mail mode changes (not Message mode) |
dfdb4cad | 3160 | |
7d301ae6 | 3161 | *** New command M-x mail-add-attachment for adding MIME attachments |
7d301ae6 | 3162 | |
dfdb4cad CY |
3163 | *** The command M-x mail-attach-file was renamed to M-x mail-insert-file. |
3164 | (Its name is misleading, since it has nothing to do with MIME | |
3165 | attachments.) The old name is now an obsolete alias to the new name. | |
3166 | ||
f2c3a9eb | 3167 | ** MH-E has been updated to MH-E version 8.3.1. |
041d709f | 3168 | See MH-E-NEWS for details. |
37221432 | 3169 | |
041d709f | 3170 | ** Modula-2 mode provides auto-indentation. |
37221432 | 3171 | |
041d709f | 3172 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
3c3d4f5b | 3173 | |
5d1ac394 | 3174 | ** nXML mode no longer binds C-RET to `nxml-complete'. |
dfdb4cad CY |
3175 | Completion is now performed via `completion-at-point', bound to C-M-i |
3176 | or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the | |
3177 | default), this performs tag completion. | |
5d1ac394 | 3178 | |
f2c3a9eb CY |
3179 | ** Org mode has been updated to version 7.8.09. |
3180 | See ORG-NEWS for details. | |
3181 | ||
041d709f | 3182 | ** Prolog mode has been completely revamped, with lots of additional |
7d301ae6 CY |
3183 | functionality such as more intelligent indentation, electricity, |
3184 | support for more variants, including Mercury, and a lot more. | |
041d709f CY |
3185 | |
3186 | ** Rmail | |
3187 | ||
3188 | *** The command `rmail-epa-decrypt' decrypts OpenPGP data | |
3189 | in the Rmail incoming message. | |
3190 | ||
50419064 GM |
3191 | *** The variable `rmail-message-filter' no longer has any effect. |
3192 | This change was made in Emacs 23.1 but was not advertised at the time. | |
3193 | Try using `rmail-show-message-hook' instead. | |
3194 | ||
717a1362 | 3195 | ** Shell mode |
dfdb4cad CY |
3196 | |
3197 | *** M-x shell prompts for the shell path name if the default directory | |
3198 | is a remote file name and neither the environment variable $ESHELL nor | |
3199 | the variable `explicit-shell-file-name' is set. | |
3200 | ||
3201 | *** TAB is now bound to the standard `completion-at-point' command, | |
3202 | which now implements the pcomplete rules for shell command completion. | |
717a1362 | 3203 | |
7d301ae6 CY |
3204 | ** SMTPmail |
3205 | ||
dfdb4cad | 3206 | *** SMTPmail now uses encrypted connections (via STARTTLS) by default |
7d301ae6 CY |
3207 | if the mail server supports them. This uses either built-in GnuTLS |
3208 | support, or the starttls.el library. Customize `smtpmail-stream-type' | |
3209 | to change this. | |
3210 | ||
7d301ae6 CY |
3211 | *** The variable `smtpmail-auth-credentials' has been removed. |
3212 | By default, the information is now stored in the file ~/.authinfo. | |
dfdb4cad CY |
3213 | This was the default value of smtpmail-auth-credentials. If you had |
3214 | customized smtpmail-auth-credentials to a list of user names and | |
3215 | passwords, those settings are not used. During your first connection | |
3216 | to the smtp server, Emacs will prompt for the user name and password, | |
3217 | and offer to save them to ~/.authinfo. Or you can manually copy the | |
3218 | credentials to ~/.authinfo. For example, if you had | |
7d301ae6 CY |
3219 | |
3220 | (setq smtpmail-auth-credentials | |
3221 | '(("mail.example.org" 25 "jim" "s!cret"))) | |

3223 | then the equivalent line in ~/.authinfo would be | |
3224 | ||
3225 | machine mail.example.org port 25 login jim password s!cret | |
3226 | ||
3227 | See the auth-source manual for more information, e.g. on encrypting | |
3228 | the credentials file. | |
3229 | ||
7d301ae6 | 3230 | *** The variable `smtpmail-starttls-credentials' has been removed. |
dfdb4cad | 3231 | If you had that set, you need to put |

34e8a2da | 3241 | ** SQL mode |
041d709f | 3242 | |
34e8a2da GM |
3243 | *** New options `sql-port', `sql-connection-alist', `sql-send-terminator', |
3244 | and `sql-oracle-scan-on'. | |
041d709f | 3245 | |
dfdb4cad | 3246 | *** New options controlling prompting for login parameters. |
34e8a2da GM |
3247 | Each supported product has a custom variable `sql-*-login-params', |
3248 | which is a list of the parameters to be prompted for before a | |
3249 | connection is established. | |
041d709f CY |
3250 | |
3251 | *** The command `sql-product-interactive' now takes a prefix argument, | |
34e8a2da | 3252 | which causes it to prompt for an SQL product. |
041d709f | 3253 | |
34e8a2da | 3254 | *** Product-specific SQL interactive commands now take prefix arguments. |
041d709f CY |
3255 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), |
3256 | given a prefix argument, prompt for a name for the SQL interactive | |
3257 | buffer. This reduces the need for calling `sql-rename-buffer'. | |
3258 | ||
3259 | *** SQL interactive modes suppress command continuation prompts, and | |
3260 | replace tabs with spaces. The first change impacts multiple line SQL | |
3261 | statements entered with C-j between each line, statements yanked into | |
3262 | the buffer and statements sent with `sql-send-*' functions. The | |
34e8a2da GM |
3263 | second prevents the MySQL and Postgres interpreters from listing |
3264 | object name completions when sent text via `sql-send-*' functions. | |
041d709f CY |
3265 | |
3266 | *** New command `sql-connect' starts a predefined SQLi session, | |
3267 | using the login parameters from `sql-connection-alist'. | |
3268 | ||
3269 | *** New "Save Connection" menu item in SQLi buffers. | |
3270 | This gathers the login params specified for the SQLi session, if it | |
3271 | was not started by a connection, and saves them as a new connection. | |
3272 | ||
34e8a2da GM |
3273 | *** New commands for listing database objects and details: |
3274 | sql-list-all and sql-list-table. | |
041d709f CY |
3275 | |
3276 | *** An API for manipulating SQL product definitions has been added. | |

7d301ae6 CY |
3295 | *** Handlers for `file-selinux-context' and `set-file-selinux-context' |
3296 | for remote machines which support SELinux. | |
58f74fe4 | 3297 | |
dfdb4cad | 3298 | ** New function `url-queue-retrieve', which behaves like url-retrieve, |
a48ec60c GM |
3299 | but with limits (`url-queue-parallel-processes', `url-queue-timeout') on |
3300 | the degree of parallelism. | |

3303 | ||
3304 | *** Support for pulling on distributed version control systems. | |
7d301ae6 CY |
3305 | The command C-x v + (`vc-pull') runs a "pull" operation, if it is |
3306 | supported (currently with Bzr, Git, and Mercurial), to update the | |
3307 | current branch and working tree. A prefix argument means to prompt | |
3308 | the user for specifics, e.g. a pull location. | |
0c32ce32 | 3309 | |
dab3703d | 3310 | *** `vc-update' is now an alias for `vc-pull'. |
0c32ce32 CY |
3311 | |
3312 | *** Support for merging on distributed version control systems. | |
7d301ae6 CY |
3313 | The command C-x v m (`vc-merge') now runs a "merge" operation, if it |
3314 | is supported (currently with Bzr, Git, and Mercurial), to merge | |
3315 | changes from another branch into the current one. It prompts for | |
3316 | specifics, e.g. a merge source. | |
0c32ce32 | 3317 | |
2afef60a | 3318 | *** New option `vc-revert-show-diff' controls whether `vc-revert' |
bbe43420 | 3319 | shows a diff while querying the user. It defaults to t. |
2afef60a | 3320 | |
d4eb88c7 CY |
3321 | *** Log entries in some Log View buffers can be toggled to display a |
3322 | longer description by typing RET (log-view-toggle-entry-display). | |
dab3703d GM |
3323 | This is currently supported for Bzr, Git, and Mercurial (to support |
3324 | another backend, define a `log-view-expanded-log-entry-function'). | |
7d301ae6 | 3325 | In the Log View buffers made by C-x v L (`vc-print-root-log'), you can |
d4eb88c7 CY |
3326 | use this to display the full log entry for the revision at point. |
3327 | ||
1c6c854e CS |
3328 | *** New command `vc-ediff' allows visual comparison of two revisions |
3329 | of a file similar to `vc-diff', but using ediff backend. | |
3330 | ||
86c60681 CY |

3332 | this was not advertised at the time. | |
3333 | ||
86c60681 CY |
3334 | *** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'. |
3335 | Since Emacs 23, it has done the same thing as `toggle-read-only', but | |
80c6d77f GM |
3336 | this was not advertised at the time. |

23d70505 GM |
3343 | |
3344 | *** partial-completion-mode (complete.el) is obsolete. | |
041d709f CY |

2c719188 | 3351 | *** pgg is obsolete (use EasyPG instead). |
041d709f CY |
3352 | |
3353 | *** sregex.el is obsolete, since rx.el is a strict superset. | |
3354 | ||
23d70505 GM |

3361 | ||
05f77e38 | 3362 | *** The Landmark game is now invoked with `landmark', not `lm'. |
c6ad2a4e | 3363 | Its functions and variables have been similarly renamed. |
05f77e38 | 3364 | |
dfdb4cad | 3365 | *** In `ido-file-completion-map', C-v is no longer bound to `ido-toggle-vc'. |
05f77e38 GM |
3366 | (This interfered with cua-mode.) |
3367 | ||

3375 | * New Modes and Packages in Emacs 24.1 | |
d445b3f8 | 3376 | |
60e56523 | 3377 | ** Occur Edit mode applies edits made in *Occur* buffers to the |
8c0f49f0 | 3378 | original buffers. It is bound to "e" in Occur mode. |
60e56523 | 3379 | |
a075a2c5 GM |
3380 | ** New global minor mode electric-pair-mode. |
3381 | When enabled, typing an open parenthesis automatically inserts the | |
3382 | matching closing one. | |
3383 | ||
3384 | ** New global minor mode electric-indent-mode. | |
3385 | When enabled, typing certain characters triggers reindentation. | |
cd3308f3 GM |
3386 | Major modes wishing to use this can set electric-indent-chars or |
3387 | electric-indent-functions. | |
a075a2c5 GM |
3388 | |
3389 | ** New global minor mode electric-layout-mode. | |
3390 | When enabled, typing certain characters automatically inserts newlines. | |
cd3308f3 | 3391 | Major modes wishing to use this can set electric-layout-rules. |
3b843809 | 3392 | |
a83ec3c9 CY |
3393 | ** tabulated-list.el provides a generic major mode for tabulated data, |
3394 | from which other modes can be derived. | |
3395 | ||
d02c9bcd SM |
3396 | ** pcase.el provides the ML-style pattern matching macro `pcase'. |
3397 | ||
7725ebb7 MA |
3398 | ** secrets.el is an implementation of the Secret Service API, an |
3399 | interface to password managers like GNOME Keyring or KDE Wallet. The | |
065f2743 MA |
3400 | Secret Service API requires D-Bus for communication. The command |
3401 | `secrets-show-secrets' offers a buffer with a visualization of the | |
3402 | secrets. | |
7725ebb7 | 3403 | |
f9e78150 MA |
3404 | ** notifications.el provides an implementation of the Desktop |
3405 | Notifications API. It requires D-Bus for communication. | |
3406 | ||
12fe5bcc MA |
3407 | ** soap-client.el supports access to SOAP web services from Emacs. |
3408 | soap-inspect.el is an interactive inspector for SOAP WSDL structures. | |

ff1796f3 | 3410 | ** New generic mode, xmodmap-generic-mode, for xmodmap files. |
ad7d6ecb | 3411 | |
53bbe3ad | 3412 | ** New emacs-lock.el package. |
7d301ae6 CY |
3413 | The previous version has been moved to obsolete/old-emacs-lock.el. |
3414 | Now, there is a proper minor mode `emacs-lock-mode'. Protection | |
3415 | against exiting Emacs and killing the buffer can be set separately. | |
3416 | The mechanism for automatically turning off protection for buffers | |
3417 | with dead inferior processes has been generalized. | |

3420 | * Incompatible Lisp Changes in Emacs 24.1 | |
6dfcbe31 | 3421 | |
7d301ae6 CY |
3422 | ** Passing a nil argument to a minor mode function call now ENABLES |
3423 | the minor mode unconditionally. This is so that you can write e.g. | |
3424 | ||
dfdb4cad | 3425 | (add-hook 'text-mode-hook 'foo-mode) |
7d301ae6 | 3426 | |
dfdb4cad CY |
3427 | to enable foo-mode in Text mode buffers, removing the need for |
3428 | `turn-on-foo-mode' style functions. This affects all mode commands | |
3429 | defined by `define-minor-mode'. If called interactively, the mode | |
3430 | command still toggles the minor mode. | |
7d301ae6 | 3431 | |
d268b4fe CY |
3432 | ** The return value of `backup-buffer' has changed. |
3433 | It is now a list of three elements, where the second element is a list | |
3434 | describing the original file's SELinux context. If Emacs or the | |
f003f294 | 3435 | system lacks SELinux support, the context list is (nil nil nil nil). |
7d301ae6 | 3436 | See "Basic SELinux support" above, under "Changes in Emacs 24.1". |
d268b4fe | 3437 | |
dfdb4cad CY |
3438 | ** `char-direction-table' and the `char-direction' function were deleted. |
3439 | They were buggy and inferior to the new support of bidirectional | |
3440 | editing introduced in Emacs 24. If you need the bidirectional | |
3441 | properties of a character, use `get-char-code-property' with the last | |
3442 | argument `bidi-class'. | |
fa6996bc | 3443 | |
470d996d TV |
3444 | ** `copy-directory' now copies the source directory as a subdirectory |
3445 | of the target directory, if the latter is an existing directory. The | |
3446 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy | |
3447 | the contents directly into a pre-existing target directory. | |
3448 | ||
9173a8fb CY |
3449 | ** For mouse click input events in the text area, the Y pixel |
3450 | coordinate in the POSITION list now counts from the top of the text | |
3451 | area, excluding any header line. Previously, it counted from the top | |
3452 | of the header line. | |
3453 | ||
7d301ae6 CY |
3454 | ** Support for "old-style" backquotes, obsolete for 10+ years, has |
3455 | been further reduced. Now a backquote not followed by a space is | |
3456 | always treated as a "new-style" backquote. Please remove all | |
3457 | "old-style" backquotes from your code. If your code uses backquotes | |
3458 | as documented in the Elisp manual, and compiles without warning, then | |
3459 | you have nothing to do in this regard. Code not following the | |
3460 | appropriate conventions may fail to compile. | |
50ab02c5 CY |
3461 | |
3462 | The most common cause of trouble seems to be an old-style backquote | |
3463 | followed by a newline. Another cause of trouble is vector notation | |
3464 | for key sequence notation: instead of [(control ,)] and [(control ')], | |
3465 | you should write [(control ?,)] and [(control ?')], which will work in | |
7d301ae6 | 3466 | older Emacsen too. |

3470 | replaced all known uses. | |
3471 | ||
7d301ae6 CY |
3472 | ** `view-buffer' now treats special mode-class in the same way that |
3473 | `view-file' has since Emacs 22 (i.e. it won't enable View mode if the | |
3474 | major mode is special). | |
fd5c9dfa | 3475 | |

0a19a6f8 JB |
3479 | and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'. |
3480 | With these alist entries omitted, `make-frame' checks the value of the | |
3481 | variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create | |
3482 | a menu-bar or tool-bar, respectively. If the alist entries are added, | |
3483 | they override the value of `menu-bar-mode'/`tool-bar-mode'. | |
6431f2e6 | 3484 | |
7d301ae6 CY |
3485 | *** The menu bar bindings's caches are not used any more. |
3486 | Use (where-is-internal <def> nil t) instead. | |
3487 | ||
fe0aa820 | 3488 | ** Regions created by mouse dragging are now normal active regions, |
dfdb4cad | 3489 | similar to those created by shift-selection (see Selection changes |
7d301ae6 CY |
3490 | above). In previous Emacs versions, these regions were delineated by |
3491 | `mouse-drag-overlay'; that variable has been removed. | |
d6d8ee7a | 3492 | |
7d301ae6 CY |
3493 | ** The fourth argument of `filter-buffer-substring' has been removed. |
3494 | If you want to remove text properties from the final result, simply | |

3558 | *** Lexically scoped interpreted functions are represented with a new form |
3559 | of function value which looks like (closure ENV ARGS &rest BODY). | |
3560 | ||
3561 | *** New macro `letrec' to define recursive local functions. | |
dfdb4cad CY |
3562 | |
3563 | *** `defvar' and `defconst' now mark the variable as special (dynamic). | |
3564 | So do `defcustom' and other forms that call `defvar' as a subroutine. | |
3565 | ||
041d709f CY |
3566 | *** New function `special-variable-p' to check whether a variable is |
3567 | declared as dynamically bound. | |
3568 | ||
88ed9e87 SM |
3569 | *** The form ((lambda ...) ...) is deprecated. |
3570 | ||
041d709f CY |
3571 | ** An Emacs Lisp testing tool is now included. |
3572 | Emacs Lisp developers can use this tool to write automated tests for | |
3573 | their code. See the ERT info manual for details. | |
3574 | ||
3575 | ** Changes for bidirectional display and editing | |
f1816485 | 3576 | |
041d709f | 3577 | *** New function `current-bidi-paragraph-direction'. |
7d301ae6 | 3578 | This returns the base direction of the paragraph at point. |
041d709f | 3579 | |
041d709f | 3580 | *** New function `bidi-string-mark-left-to-right'. |
dfdb4cad CY |
3581 | Given a string containing characters from right-to-left scripts, this |
3582 | function returns another string which can be safely inserted into a | |
3583 | buffer, such that any following text will be always displayed to the | |
7d301ae6 CY |
3584 | right of that string. (This works by appending an invisible Unicode |
3585 | "LEFT-TO-RIGHT MARK" character if the argument string might need it.) | |
041d709f | 3586 | |
7d301ae6 | 3587 | This is useful when the buffer has overall left-to-right paragraph |
dfdb4cad CY |
3588 | direction and you need to insert a string whose contents are not known |
3589 | in advance, without disrupting the layout of the line. | |
041d709f | 3590 | |
bee0fcef | 3591 | ** Window changes |
dfdb4cad | 3592 | |
c4682d18 MR |
3593 | *** Window tree functions are accessible in Elisp. |
3594 | Functions are provided to return the parent, siblings or child windows | |
3595 | of any window including internal windows (windows not associated with a | |
3596 | buffer) in the window tree. | |
dfdb4cad | 3597 | |
24300f5f CY |
3598 | **** New function `window-valid-p' gives non-nil for live and internal |
3599 | windows. | |
dfdb4cad | 3600 | |
24300f5f | 3601 | **** Window manipulation can deal with internal windows. |
c4682d18 MR |
3602 | Many window handling functions like `split-window', `delete-window', or |
3603 | `delete-other-windows' as well as the window resizing functions can now | |
3604 | act on any window including internal ones. | |
dfdb4cad | 3605 | |
c4682d18 MR |
3606 | *** window-total-height/-width vs window-body-height/-width. |
3607 | The function `window-height' has been renamed to `window-total-height' | |
3608 | and `window-width' has been renamed to `window-body-width'. The old | |
3609 | names are provided as aliases. Two new functions `window-total-width' | |
3610 | and `window-body-height' are provided. | |
dfdb4cad | 3611 | |
c4682d18 MR |
3612 | *** Window parameters specific to window handling functions. |
3613 | For each window you can specify a parameter to override the default | |
3614 | behavior of a number of functions like `split-window', `delete-window' | |
ed6235ea MR |
3615 | and `delete-other-windows'. The variable `ignore-window-parameters' |
3616 | allows to ignore processing such parameters. | |
dfdb4cad | 3617 | |
c4682d18 | 3618 | *** New semantics of third argument of `split-window'. |
c4682d18 MR |
3619 | The third argument of `split-window' has been renamed to SIDE and can be |
3620 | set to any of the values 'below, 'right, 'above, or 'left to make the | |
3621 | new window appear on the corresponding side of the window that shall be | |
3622 | split. Any other value of SIDE will cause `split-window' to split the | |
3623 | window into two side-by-side windows as before. | |
dfdb4cad | 3624 | |
c4682d18 | 3625 | *** Window resizing functions. |
487ffd7a | 3626 | A new standard function for resizing windows called `window-resize' has |
c4682d18 MR |
3627 | been introduced. This and all other functions for resizing windows no |
3628 | longer delete any windows when they become too small. | |
dfdb4cad | 3629 | |
b3c0dbfd MR |
3630 | *** Deleting the selected window now selects the most recently selected |
3631 | live window on that frame instead. | |
dfdb4cad | 3632 | |
c4682d18 MR |
3633 | *** `adjust-window-trailing-edge' adjustments. |
3634 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | |
3635 | is able to resize other windows if a window adjacent to the trailing | |
3636 | edge cannot be shrunk any more. This makes its behavior more similar to | |
3637 | that of Emacs 21 without compromising, however, its inability to delete | |
3638 | windows which was introduced in Emacs 22. | |
dfdb4cad | 3639 | |
c4682d18 MR |
3640 | *** Window-local buffer lists. |
3641 | Windows now have local buffer lists. This means that removing a buffer | |
3642 | from display in a window will preferably show the buffer previously | |
3643 | shown in that window with its previous window-start and window-point | |
3644 | positions. This also means that the same buffer may be automatically | |
3645 | shown twice even if it already appears in another window. | |
dfdb4cad | 3646 | |
bee0fcef CY |
3647 | *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW, |
3648 | which if non-nil requires the buffer to be displayed in the currently | |
3649 | selected window, signaling an error otherwise. If nil, another window | |
3650 | can be used, e.g. if the selected one is strongly dedicated. | |
dfdb4cad | 3651 | |
0a2132ba | 3652 | *** `split-window-vertically' and `split-window-horizontally' renamed |
2d197ffb CY |
3653 | to `split-window-below' and `split-window-right' respectively. |
3654 | The old names are kept as aliases. | |
dfdb4cad | 3655 | |
0a2132ba CY |
3656 | *** Display actions |
3657 | ||
3658 | **** The second arg to `display-buffer' and `pop-to-buffer' is now | |
3659 | named ACTION, and takes a display action of the same form as | |
3660 | `display-buffer-base-action' (see Changes, above). A non-nil, | |
3661 | non-list value is treated specially, as the old meaning. | |
3662 | ||
3663 | **** New variable `display-buffer-overriding-action'. | |
3664 | ||
3665 | **** The procedure of `display-buffer' etc. to choose a window is | |
3666 | determined by combining `display-buffer-overriding-action', | |
3667 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', | |
3668 | and `display-buffer-fallback-action'. The second and fourth of these | |
3669 | are user-customizable variables. | |
3670 | ||
3671 | See the docstring of `display-buffer' for details. | |
bee0fcef | 3672 | |
20d2304d CY |
3673 | *** New functions `window-state-get' and `window-state-put'. |
3674 | These functions allow to save and restore the state of an arbitrary | |
3675 | frame or window as an Elisp object. | |
3676 | ||
a2a25d24 | 3677 | ** Completion |
041d709f | 3678 | |
7d301ae6 CY |
3679 | *** New variable `completion-extra-properties' used to specify extra |
3680 | properties of the current completion: | |
a2a25d24 SM |
3681 | - :annotate-function, same as the old completion-annotate-function. |
3682 | - :exit-function, function to call after completion took place. | |
3683 | ||
7d301ae6 CY |
3684 | *** Functions on `completion-at-point-functions' can return any of the |
3685 | properties valid for `completion-extra-properties'. | |
a2a25d24 | 3686 | |
7d301ae6 | 3687 | *** `completion-annotate-function' is obsolete. |
a2a25d24 | 3688 | |
620c53a6 SM |
3689 | *** New `metadata' method for completion tables. The metadata thus returned |
3690 | can specify various details of the data returned by `all-completions': | |
3691 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | |
3692 | used to select a style in completion-category-overrides. | |
3693 | - `annotation-function' to add annotations in *Completions*. | |
3694 | - `display-sort-function' to specify how to sort entries in *Completions*. | |
3695 | - `cycle-sort-function' to specify how to sort entries when cycling. | |
3696 | ||
7d301ae6 CY |
3697 | *** `minibuffer-local-filename-must-match-map' is not used any more. |
3698 | Instead, the bindings in `minibuffer-local-filename-completion-map' | |
3699 | are combined with `minibuffer-local-must-match-map'. | |
de09aa52 CY |
3700 | |
3701 | *** New variable `completing-read-function' allows overriding the | |
3702 | behavior of `completing-read'. | |
3703 | ||
f042970d | 3704 | ** `glyphless-char-display' can now distinguish between graphical and |
16a43933 CY |
3705 | text terminal display, via a char-table entry that is a cons cell. |
3706 | ||
7d301ae6 | 3707 | ** `pre-command-hook'/`post-command-hook' are not reset to nil on error. |
f6d62986 SM |
3708 | Instead, the offending function is removed. |
3709 | ||
b1f6fa26 CY |
3710 | ** New hook types |
3711 | ||
3712 | *** New function `run-hook-wrapped' for running an abnormal hook by | |
3713 | passing the hook functions as arguments to a "wrapping" function. | |
e7bc51d0 | 3714 | Like `run-hook-with-args-until-success', it stops at the first |
5385447f | 3715 | non-nil return value. |
e7bc51d0 | 3716 | |
b1f6fa26 CY |
3717 | *** New macro `with-wrapper-hook' for running an abnormal hook as a |
3718 | set of "wrapping" filters, similar to around advice. | |
54521c99 GM |
3719 | (A version of this macro was actually added in Emacs 23.2 but was not |
3720 | advertised at the time.) | |
f6d62986 | 3721 | |
0b19b281 | 3722 | ** Debugger changes |
dfdb4cad | 3723 | |
0b19b281 | 3724 | *** New macro `condition-case-unless-debug' (this was actually added in |
1be3ca5a | 3725 | Emacs 23.1 as condition-case-no-debug, but not advertised) |
dfdb4cad | 3726 | |
0b19b281 | 3727 | *** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised. |
dfdb4cad | 3728 | |
0b19b281 | 3729 | *** Variable `stack-trace-on-error' removed. |
dfdb4cad | 3730 | |
0b19b281 CY |
3731 | *** The debugger can now "continue" from an error, which means it will |
3732 | jump to the error handler as if the debugger had not been invoked | |
3733 | instead of jumping all the way to the top-level. | |
dfdb4cad | 3734 | |
0b19b281 CY |
3735 | *** Set `debug-on-event' to enter the debugger on events like SIGUSR1. |
3736 | This can be useful when `inhibit-quit' is set. | |
d6b1d521 | 3737 | |
953cebf5 | 3738 | ** The new function `server-eval-at' allows evaluation of Lisp forms on |
37576acd | 3739 | named Emacs server instances. |
7deebf1b | 3740 | |
1b9f60cc GM |
3741 | ** `call-process' and `call-process-region' allow a `(:file "file")' spec |
3742 | to redirect STDOUT to a file. | |
7deebf1b | 3743 | |
7d301ae6 CY |
3744 | ** The function `format-time-string' now supports the %N directive, |
3745 | for higher-resolution time stamps. | |
da97a9e6 | 3746 | |
0b19b281 | 3747 | ** New input reading functions |
dfdb4cad | 3748 | |
0b19b281 CY |
3749 | *** New function `read-char-choice' reads a restricted set of |
3750 | characters, discarding any inputs not inside the set. | |
dfdb4cad | 3751 | |
0b19b281 CY |
3752 | *** The command `read-color' now requires a match for a color name |
3753 | or RGB triplet, instead of signaling an error if the user provides | |
3754 | invalid input. | |
dfdb4cad | 3755 | |
0b19b281 | 3756 | **** `facemenu-read-color' is now an alias for `read-color'. |
3ef01959 | 3757 | |
2e288d54 JB |
3758 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
3759 | The variable is now used to load all kind of supported dynamic libraries, | |
3760 | not just image libraries. The previous name is still available as an | |
3761 | obsolete alias. | |
3762 | ||
0b19b281 | 3763 | ** Syntax parsing changes |
dfdb4cad | 3764 | |
0b19b281 | 3765 | *** New variable `syntax-propertize-function'. |
04e2ce72 | 3766 | This replaces `font-lock-syntactic-keywords' which is now obsolete. |
cf38dd42 SM |
3767 | This allows syntax-table properties to be set independently from font-lock: |
3768 | just call syntax-propertize to make sure the text is propertized. | |
3769 | Together with this new variable come a new hook | |
3770 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
3771 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
3772 | as-is; and syntax-propertize-rules which provides a new way to specify | |
3773 | syntactic rules. | |
dfdb4cad | 3774 | |
0b19b281 | 3775 | *** Syntax tables support a new "comment style c" additionally to style b. |
a2e5caf7 | 3776 | |
7d301ae6 | 3777 | ** New hook `post-self-insert-hook', run after `self-insert-command'. |
041d709f | 3778 | |
4e2db1fe | 3779 | ** frame-local variables cannot be let-bound any more. |
041d709f | 3780 | |
15de15c6 | 3781 | ** Major and minor mode changes |
dfdb4cad | 3782 | |
0b19b281 CY |
3783 | *** `set-auto-mode' now respects mode: local variables at the end of files, |
3784 | as well as those in the -*- line. | |
dfdb4cad | 3785 | |
15de15c6 CY |
3786 | *** `prog-mode' is a new major mode from which programming modes |
3787 | should be derived. | |
dfdb4cad | 3788 | |
15de15c6 CY |
3789 | **** `prog-mode-hook' can be used to enable features for programming |
3790 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable | |
3791 | on-the-fly spell checking for comments and strings. | |
dfdb4cad | 3792 | |
15de15c6 CY |
3793 | *** New hook `change-major-mode-after-body-hook', run by |
3794 | `run-mode-hooks' just before any other mode hooks. | |
dfdb4cad | 3795 | |
7a9a2fc6 GM |
3796 | *** Enabled globalized minor modes can be disabled in specific major modes. |
3797 | If the global mode is global-FOO-mode, then run (FOO-mode -1) in the | |
3798 | major mode's hook, where FOO-mode toggles the mode on a per-buffer basis. | |
dfdb4cad | 3799 | |
feb8a83a | 3800 | *** `define-minor-mode' accepts new keywords :variable, :after-hook. |
f44379e7 | 3801 | |
7d301ae6 CY |
3802 | ** File-handling changes |
3803 | ||
7d301ae6 | 3804 | *** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
3805 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
3806 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
3807 | argument is supplied (see Trash changes, above). | |
53967e09 | 3808 | |
7d301ae6 | 3809 | *** New file predicates: `file-equal-p', `file-in-directory-p'. |
ec70a47d | 3810 | |
4039c786 CY |
3811 | ** Tool-bars can display separators. |
3812 | Tool-bar separators are handled like menu separators in menu-bar maps, | |
94975270 | 3813 | i.e. via menu entries of the form `(menu-item "--")'. |
9317e499 | 3814 | |
00fe2df1 JL |
3815 | ** Image API |
3816 | ||
18af70d0 CY |
3817 | *** Animated images support (currently animated gifs only). |
3818 | ||
3819 | **** `image-animated-p' returns non-nil if an image can be animated. | |
3820 | ||
3821 | **** `image-animate' animates a supplied image spec. | |
3822 | ||
3823 | **** `image-animate-timer' returns the timer object for an image that | |
3824 | is being animated. | |
00fe2df1 | 3825 | |
7cb76fe0 GM |
3826 | *** `image-extension-data' has been renamed to `image-metadata'. |
3827 | The old name is an obsolete alias to the new one. | |
1546c559 | 3828 | |
b4ac6e8c GM |
3829 | *** Image mode can view any image type that ImageMagick supports. |
3830 | This requires Emacs to be built with ImageMagick support. | |
7d301ae6 CY |
3831 | |
3832 | **** New function `imagemagick-types', defined if ImageMagick support | |
3833 | is enabled, returns a list of image file extensions that your | |
3834 | ImageMagick installation supports. | |
3835 | ||
3836 | **** New function `imagemagick-register-types' enables ImageMagick | |
3837 | image types in Image mode and in `create-image' and other helper | |
3838 | functions. | |
3839 | ||
3840 | **** New option `imagemagick-types-inhibit' excludes certain | |
3841 | ImageMagick image types from `imagemagick-register-types'. | |
3842 | ||
7d301ae6 CY |
3843 | **** With ImageMagick support, there are extra Image mode commands to |
3844 | resize and rotate images: `image-transform-fit-to-height', | |
3845 | `image-transform-fit-to-width', `image-transform-set-rotation', and | |
3846 | `image-transform-set-scale'. | |
041d709f | 3847 | |
7d301ae6 CY |
3848 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
3849 | passes it to the mail user agent function. This argument specifies an | |
3850 | action for returning to the caller after finishing with the mail. For | |
3851 | example, this is used by Rmail to optionally delete a mail window. | |
b4ac6e8c | 3852 | |
71c17aec | 3853 | ** XML and HTML parsing |
483ab230 CY |
3854 | If Emacs is compiled with libxml2 support, there are two new |
3855 | functions: `libxml-parse-html-region' (which parses "real world" HTML) | |
3856 | and `libxml-parse-xml-region' (which parses XML). Both return an | |
3857 | Emacs Lisp parse tree. | |
4b9832a6 | 3858 | |
7d301ae6 | 3859 | ** Networking and encryption changes |
e2574f2c | 3860 | |
7d301ae6 CY |
3861 | *** `open-network-stream' can now be used to open an encrypted stream. |
3862 | It now accepts an optional `:type' parameter for initiating a TLS | |
3863 | connection, directly or via STARTTLS. To do STARTTLS, additional | |
3864 | parameters (`:end-of-command', `:success', `:capabilities-command') | |
3865 | must also be supplied. | |
3866 | ||
3867 | *** New library gnutls.el. | |
dfdb4cad CY |
3868 | The new function `gnutls-available-p' returns non-nil if Emacs is |
3869 | built with GnuTLS support. The main entry points are | |
3870 | `open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use | |
3871 | these functions through `open-network-stream', because that can | |
7d301ae6 CY |
3872 | upgrade connections through STARTTLS opportunistically or use plain |
3873 | SSL, depending on your needs. For debugging, set `gnutls-log-level' | |
3874 | greater than 0. | |
3875 | ||
7d301ae6 CY |
3876 | *** New primitive `secure-hash' that supports many secure hash algorithms: |
3877 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library | |
3878 | sha1.el has been removed. The `sha1' feature is provided by default. | |
71c17aec | 3879 | |
a6020335 MH |
3880 | ** Isearch |
3881 | ||
3882 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | |
3883 | ||
9326ba26 CY |
3884 | ** Progress reporters can now "spin". |
3885 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
3886 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
3887 | time you call `progress-reporter-update' on that progress reporter, | |
3888 | with a nil or omitted VALUE argument, the reporter message is | |
3889 | displayed with a "spinning bar". | |
3890 | ||
3e214b50 JB |
3891 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is |
3892 | being reverted, even if the buffer has a local `revert-buffer-function'. | |
3893 | ||
001bf877 GM |
3894 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. |
3895 | If delayed-warnings-list is non-nil, the command loop calls | |
7d301ae6 CY |
3896 | `delayed-warnings-hook' after `post-command-hook'. At present, this |
3897 | is only used by Emacs on some platforms to display warnings during | |
3898 | startup, which might otherwise not be noticed. This uses the | |

3901 | ** rx.el has a new `group-n' construct for explicitly numbered groups. |

3903 | ** New function `make-composed-keymap' that constructs a new keymap |
3904 | from multiple input maps. You can use this to make a keymap that | |
3905 | inherits from multiple maps, eg: | |
3906 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) | |

c8f6ec5c GM |
3908 | ** New function `string-prefix-p'. |
3909 | (This was actually added in Emacs 23.2 but was not advertised at the time.) | |
3910 | ||
27f7ef2f | 3911 | ** New reader macro ## that stands for the empty symbol. |
43dc9f5b AS |
3912 | This means that the empty symbol can now be read back. Also, #: by itself |
3913 | (when not immediately followed by a possible symbol character) stands for | |
3914 | an empty uninterned symbol. | |

3921 | Rather than setting this to t, disable Tooltip mode instead. | |
3922 | ||
041d709f CY |
3923 | *** buffer-substring-filters is obsolete. |
3924 | Use `filter-buffer-substring-functions' instead. | |

a2f0118c GM |
3937 | and also when HOME is set to C:\ by default. |
3938 | ||

04779484 | 3940 | |

e3aef5c6 | 3942 | |
7a22e700 | 3943 | *** --distfiles specifies files to be included in binary distribution. |
e2574f2c | 3944 | |

3945 | *** --without-gnutls disables automatic GnuTLS detection. |
3946 | ||

e2574f2c | 3948 | |

e3aef5c6 | 3950 | |

3951 | ** The Lisp function `w32-default-color-map' is now obsolete. |
3952 | (It is only used internally in the Emacs C code.) | |
5430d399 | 3953 | |
1f5e1a16 GM |
3954 | ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but |
3955 | reappear on mouse-over. (Requires OS X 10.6 or later.) | |
04e2ce72 | 3956 | |
ad7c802c CY |
3957 | ** On Mac OS X, dragging a file into Emacs visits the file, like on |
3958 | other platforms, rather than inserting its contents into the buffer. | |
