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

28 | ** Building Emacs now requires GNU make. | |
29 | ||
37eccff4 PE |
30 | ** By default, Emacs no longer works on IRIX. We expect that Emacs |
31 | users are not affected by this, as SGI stopped supporting IRIX in | |
32 | December 2013. If you are affected, please send a bug report. You | |
33 | should be able to work around the problem either by porting the Emacs | |
34 | undumping code to GCC under IRIX, or by configuring --with-wide-int, | |
35 | or by sticking with Emacs 24.4. | |

70c8f5ca | 100 | ** Emacs can now be compiled with ACL support. |
7c3d167f RF |
101 | This happens by default if a suitable support library is found at |
102 | build time, like libacl on GNU/Linux. To prevent this, use the | |
81a15753 | 103 | configure option `--disable-acl'. See below for related features. |
7c3d167f | 104 | |
81a15753 | 105 | --- |
70c8f5ca | 106 | ** Emacs can now be compiled with file notification support. |
671d4bfc GM |
107 | This happens by default if a suitable system library is found at |
108 | build time. To prevent this, use the configure option | |
e873a22e | 109 | `--without-file-notification'. See below for file-notify features. |
81a15753 GM |
110 | This feature is not available for the Nextstep port. |
111 | ||
112 | --- | |
113 | ** Emacs can now be compiled with zlib support. | |
114 | This happens by default if zlib is present, which it normally is. | |
115 | To prevent this, use the configure option `--without-zlib'. | |
116 | This provides the function `zlib-decompress-region'; see below for details. | |
2f23b3ab | 117 | |
d65a92bb | 118 | --- |
70c8f5ca CY |
119 | ** The configure option `--without-compress-info' has been generalized, |
120 | and renamed to `--without-compress-install'. It now prevents compression | |
335142f9 GM |
121 | of _any_ files during installation. |
122 | ||
d65a92bb | 123 | --- |
70c8f5ca | 124 | ** The configure option `--with-crt-dir' has been removed. |
a22359a7 | 125 | It is no longer needed, as the crt*.o files are no longer linked specially. |
f1e496a5 | 126 | |
d65a92bb | 127 | --- |

128 | ** Directories passed to configure option `--enable-locallisppath' are |
129 | no longer created during installation. | |

9524a13d | 131 | --- |
8251c3f8 | 132 | ** Emacs for NS (Mac OS X, GNUstep) can be built with ImageMagick support. |
81a15753 | 133 | This requires pkg-config to be available at build time. |

95a32efb | 136 | * Startup Changes in Emacs 24.4 |
c57b2d76 | 137 | |
17e0445b GM |
138 | +++ |
139 | ** When initializing `load-path', an empty element in the EMACSLOADPATH | |
140 | environment variable (either leading, e.g., ":/foo"; trailing, e.g., | |
141 | "/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default | |
142 | load-path (the one that would have been used if EMACSLOADPATH was unset). | |
143 | This makes it easier to _extend_ the load-path via EMACSLOADPATH | |
144 | (previously, EMACSLOADPATH had to specify the complete load-path, | |
145 | including the defaults). (In older versions of Emacs, an empty element | |
146 | was replaced by ".", so use an explicit "." now if that is what you want.) | |
147 | ||
a0833f62 GM |
148 | +++ |
149 | ** The -L option, which normally prepends its argument to load-path, | |
2df10228 GM |
150 | will instead append, if the argument begins with `:' (or `;' on MS Windows; |
151 | i.e., `path-separator'). | |
a0833f62 | 152 | |
06a4f110 GM |
153 | +++ |
154 | ** If you use either site-load.el or site-init.el to customize the dumped | |
155 | Emacs executable, any changes to `load-path' that these files make | |
156 | will no longer be present after dumping. To affect a permanent change | |
157 | to `load-path', use the `--enable-locallisppath' option of `configure'. | |
158 | ||
70c8f5ca CY |
159 | +++ |
160 | ** The user option `initial-buffer-choice' can now specify a function | |
161 | to set up the initial buffer. | |

95a32efb | 164 | * Changes in Emacs 24.4 |
c6c08d3f | 165 | |
d2b94b15 | 166 | +++ |
81a15753 GM |
167 | ** New function `zlib-decompress-region', which decompresses gzip- and |
168 | zlib-format compressed data using built-in zlib support, if available. | |
169 | ||
d8a2993d TZ |
170 | +++ |
171 | ** New option `gnutls-verify-error', if non-nil, means that Emacs | |
172 | should reject SSL/TLS certificates that GnuTLS determines as invalid. | |
173 | (This option defaults to nil at present, but this is expected to change | |
174 | in a future release.) | |
175 | ||
0a12fca0 EZ |
176 | +++ |
177 | ** Emacs now supports menus on text-mode terminals. | |
178 | If the terminal supports a mouse, clicking on the menu bar, or on | |
179 | sensitive portions of the mode line or header line, will drop down the | |
180 | menu defined at that position. Likewise, clicking C-mouse-2 or | |
181 | C-mouse-2 or C-mouse-3 on the text area will pop up the menus defined | |
182 | for those locations. | |
183 | ||
184 | If the text terminal does not support a mouse, you can activate the | |
185 | first menu-bar menu by typing F10, which invokes `menu-bar-open'. | |
186 | ||
187 | If you want the previous behavior, whereby F10 invoked `tmm-menubar', | |
188 | customize the option `tty-menu-open-use-tmm' to a non-nil value. | |
f8b18150 GM |
189 | (Typing M-` always invokes `tmm-menubar', even if `tty-menu-open-use-tmm' |
190 | is nil.) | |
0a12fca0 | 191 | |
a34a0ac8 | 192 | +++ |
70c8f5ca CY |
193 | ** The *Messages* buffer is created in `messages-buffer-mode', |
194 | a new major mode, with read-only status. Any code that might create | |
195 | the *Messages* buffer should call the function `messages-buffer' to do | |
196 | so and set up the mode. | |
61a5bb85 | 197 | |
6f876149 | 198 | +++ |
81a15753 GM |
199 | ** Emacs can now support ACLs (access control lists). |
200 | This requires a suitable support library to be found at build time. | |
6f876149 GM |
201 | On GNU/Linux, the POSIX ACL interface is used via libacl. |
202 | On MS-Windows, the NT Security APIs are used to emulate the POSIX interface. | |
81a15753 | 203 | |
7c3d167f RF |
204 | +++ |
205 | *** Emacs preserves the ACL entries of files when backing up. | |
206 | +++ | |
207 | *** New functions `file-acl' and `set-file-acl' get and set the ACL | |
6f876149 | 208 | entries of a file. |
7c3d167f | 209 | |
4e3f9230 YM |
210 | ** Multi-monitor support has been added. |
211 | ||
915f4bce | 212 | +++ |
4e3f9230 YM |
213 | *** New functions `display-monitor-attributes-list' and |
214 | `frame-monitor-attributes' can be used to obtain information about | |
215 | each physical monitor on multi-monitor setups. | |
216 | ||
7ebd57e9 | 217 | +++ |
cf13177e YM |
218 | *** The functions `display-pixel-width' and `display-pixel-height' now |
219 | behave consistently among the platforms: they return the pixel width | |
220 | or height for all physical monitors associated with the given display | |
7ebd57e9 | 221 | as if they were on X. To get information for each physical |
cf13177e YM |
222 | monitor, use the new functions above. Similar notes also apply to |
223 | `x-display-pixel-width', `x-display-pixel-height', `display-mm-width', | |
224 | `display-mm-height', `x-display-mm-width', and `x-display-mm-height'. | |
225 | ||
70c8f5ca CY |
226 | +++ |
227 | ** The cursor stops blinking after 10 blinks (by default) on X and NS. | |
228 | You can change the default by customizing `blink-cursor-blinks'. | |
61e56e2c | 229 | |
70c8f5ca CY |
230 | +++ |
231 | ** In keymaps where SPC scrolls forward, S-SPC now scrolls backward. | |
232 | This affects View mode, etc. | |
233 | ||
03607929 | 234 | +++ |
b54b4b12 | 235 | ** The default value of `make-backup-file-name-function' is no longer nil. |
d60a0a17 GM |
236 | Instead it defaults to a function that does what the nil value used to. |
237 | ||
70c8f5ca | 238 | ** Help changes |
f88ac3bb | 239 | |
98104aea | 240 | +++ |
70c8f5ca CY |
241 | *** The command `apropos-variable' is renamed to `apropos-user-option'. |
242 | `apropos-user-option' shows all user options while `apropos-variable' | |
243 | shows all variables. When called with a universal prefix argument, | |
244 | the two commands swap their behaviors. When `apropos-do-all' is | |
245 | non-nil, they output the same results. | |
18c26d81 | 246 | |
70c8f5ca CY |
247 | +++ |
248 | *** The key `?' now describes prefix bindings, like `C-h'. | |
6585d561 | 249 | |
6faf982a | 250 | --- |
8251c3f8 | 251 | *** The command `describe-function' has been extended for EIEIO. |
3ca34b22 | 252 | Running it on constructors will show a full description of the |
d6a62260 | 253 | generated class. For generic functions, it will show all |
3ca34b22 DE |
254 | implementations together with links to the source. The old commands |
255 | `describe-class', `describe-constructor' and `describe-generic' were | |
256 | removed. | |
257 | ||
44e76f9d GM |
258 | --- |
259 | *** The function `quail-help' is no longer an interactive command. | |
8251c3f8 | 260 | Use `C-h C-\' (`describe-input-method') instead. |
6950f152 | 261 | |

262 | ** ImageMagick |
263 | ||
4e7d26fc | 264 | +++ |
8251c3f8 | 265 | *** ImageMagick images now support the :max-width and :max-height keywords. |
b29daf07 | 266 | |
7b997b14 GM |
267 | +++ |
268 | *** When using `create-image' with image data, you can pass a :format | |
269 | attribute (via the property-list argument) in order to help | |
270 | ImageMagick detect the image type. The value should be a MIME | |
271 | content-type that is found in the new variable `image-format-suffixes'. | |
b29daf07 | 272 | |
70c8f5ca | 273 | ** Frame and window changes |
da9ea6d9 | 274 | |
87132570 MR |
275 | +++ |
276 | *** The function `window-in-direction' introduced in Emacs 24.1 now | |
1920914a | 277 | takes additional arguments for specifying a reference point, wrapping |
87132570 MR |
278 | selection around frame borders, and specifying ways to select the |
279 | minibuffer window. | |
280 | ||
70c8f5ca CY |
281 | +++ |
282 | *** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized', | |
283 | bound to <f11> and M-<f10>, respectively. | |
0a749fa0 | 284 | |
dc20a9d2 | 285 | +++ |
70c8f5ca CY |
286 | *** New hooks `focus-in-hook', `focus-out-hook'. |
287 | These are normal hooks run when an Emacs frame gains or loses input focus. | |
288 | ||
21e18b30 | 289 | +++ |
ca58fa73 GM |
290 | *** Emacs can now change frame sizes in units of pixels, rather than |
291 | text rows or columns. When maximizing a frame or making it fullscreen, | |
292 | remaining extra pixels are no longer given to the minibuffer, the rightmost | |
293 | fringe, or other unusable space, but are distributed among the text | |
294 | areas of the frame's windows. If the new option `frame-resize-pixelwise' | |
295 | is non-nil, all frame size changes happen pixelwise and set the | |
296 | corresponding size hints for the window manager. | |
297 | ||
21e18b30 | 298 | +++ |
ca58fa73 GM |
299 | *** Emacs can now change window sizes in units of pixels. |
300 | Mouse-dragging a mode line or window divider now changes the size of | |
301 | adjacent windows pixelwise. If the new option `window-resize-pixelwise' | |
302 | is non-nil, functions like `balance-windows-area' and `fit-window-to-buffer' | |
303 | resize windows pixelwise. Most functions for changing or accessing | |
304 | window sizes now have an additional argument that allows changes to apply, | |
305 | or values to be returned, in pixels instead of lines/columns. | |
b7aa5ad6 | 306 | |
cac0a1d6 MR |
307 | +++ |
308 | *** The functions `window-body-height' and `window-body-width' now never | |
309 | count partially visible lines or columns if called with a nil PIXELWISE | |
310 | argument. | |
311 | ||
21e18b30 | 312 | +++ |
b7aa5ad6 MR |
313 | *** Emacs can now draw dividers between adjacent windows. To put |
314 | dividers between side-by-side/vertically stacked windows customize the | |
315 | frame parameters `right-divider-width' and `bottom-divider-width' to | |
316 | some positive integer. You can drag dividers with the mouse (they show | |
317 | a corresponding cursor when the mouse hovers over them). You can change | |
318 | the appearance of dividers by customizing the faces `window-divider', | |
319 | `window-divider-first-pixel', and `window-divider-last-pixel'. The last | |
320 | two are useful to provide a 3D effect, or to better distinguish dividers | |
321 | from surrounding display objects. | |
322 | ||
21e18b30 | 323 | +++ |
b7aa5ad6 MR |
324 | *** New functions are provided to return the pixel sizes of window |
325 | components, namely `window-scroll-bar-width', `window-mode-line-height' | |
326 | `window-header-line-height', `window-right-divider-width' and | |
327 | `window-bottom-divider-width'. | |
328 | ||
21e18b30 | 329 | +++ |
b7aa5ad6 MR |
330 | *** The new function `window-text-pixel-size' returns the size of the |
331 | text of a window's buffer in pixels. This allows functions like | |
332 | `fit-frame-to-buffer' and `fit-window-to-buffer' to accurately fit a | |
333 | window to its buffer as it will be displayed. | |
334 | ||

cac0a1d6 | 336 | *** `fit-window-to-buffer' can now resize windows in both dimensions. |
b7aa5ad6 | 337 | This behavior is controlled by the new option |
cac0a1d6 MR |
338 | `fit-window-to-buffer-horizontally'. The new option |
339 | `fit-frame-to-buffer' allows to fit the window's frame to its buffer. | |

21e18b30 | 341 | +++ |
cac0a1d6 MR |
342 | *** `fit-frame-to-buffer' now fits frames in both dimensions. The new |
343 | options `fit-frame-to-buffer-margins' and `fit-frame-to-buffer-sizes' | |
b7aa5ad6 MR |
344 | control the size of the frame and its position on screen. |

b7aa5ad6 MR |
347 | *** Temp Buffer Resize Mode can now adjust height and width of windows |
348 | and frames. `temp-buffer-resize-mode' is now able to adjust the height | |
349 | and the width of a window displaying a temporary buffer. The new option | |
350 | `temp-buffer-max-width' allows to control the width of temporary buffer | |
351 | windows. Moreover, if the new option `fit-frame-to-buffer' is non-nil | |
352 | and the buffer appears in the root window of a frame, Temp Buffer Resize | |
353 | Mode will try to adjust width and/or height of the frame. | |

356 | *** `split-window' is now a non-interactive function, not a command. | |
357 | As a command, it was a special case of `C-x 2' (`split-window-below'), | |
358 | and as such superfluous. After being reimplemented in Lisp, its | |
359 | interactive form was mistakenly retained. | |

70c8f5ca CY |
370 | *** New option `scroll-bar-adjust-thumb-portion'. |
371 | Available only on X, this option allows to control over-scrolling | |

b20e120e | 1510 | rather than inheriting from it. In other words, setting a face via a |

1561 | ** Changes in encoding and decoding of text |
1562 | ||
1563 | --- | |
1564 | *** New coding-system `prefer-utf-8'. | |
1565 | This is like `undecided' but prefers UTF-8 on decoding if the text to | |
1566 | be decoded does not contain any invalid UTF-8 sequences. On encoding, | |
1567 | any non-ASCII characters are automatically encoded as UTF-8. | |
1568 | ||
1569 | --- | |
1570 | *** New attributes of coding-systems whose type is `undecided'. | |
1571 | Two new attributes, `:inhibit-null-byte-detection' and | |
1572 | `:inhibit-iso-escape-detection', determine how to detect encoding of | |
1573 | text that includes null bytes and ISO-2022 escape sequences, | |
1574 | respectively. Each of these attributes can be either nil, zero, or | |
1575 | t. If it is t, decoding text ignores null bytes and, respectively, | |
1576 | ISO-2022 sequences. If it is nil, null bytes cause text to be decoded | |
1577 | with no-conversion and ISO-2022 sequences cause Emacs to assume the | |
1578 | text is encoded in one of the ISO-2022 encodings, such as | |
1579 | iso-2022-7bit. If the value is zero, Emacs consults the variables | |
1580 | inhibit-null-byte-detection and inhibit-iso-escape-detection, which | |
1581 | see. | |
1582 | The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer | |
1583 | UTF-8 encoding and decoding, whenever possible. | |
1584 | ||
1585 | These attributes are only meaningful for coding-systems of type | |
1586 | `undecided'. (The type of a coding-system is determined by its | |
1587 | `:coding-type' attribute and can be accessed by calling the | |
1588 | `coding-system-type' function.) | |

1601 | ** Minor internal changes to the details of lock files. | |
1602 | The lock for DIR/FILE is now _always_ DIR/.#FILE. | |
1603 | If DIR/.#FILE already exists and is not an Emacs lock file, | |
1604 | Emacs makes no attempt to lock DIR/FILE. (Previously, it fell back to | |
1605 | numbered lock files DIR/.#FILE.0...). | |
1606 | On file systems that do not support symbolic links, the lock is now a | |
1607 | regular file with contents being what would have been in the symlink. | |

1620 | ** The procedure for building Emacs on MS-Windows has changed. |
1621 | It is now built by running the same configure script as on all other | |
1622 | platforms. This requires the MSYS environment and MinGW development | |
1623 | tools. See the updated instructions in nt/INSTALL for details. | |
671d4bfc GM |
1624 | |
1625 | Using the Posix configure script and Makefile's also means a change in | |
1626 | the directory structure of the Emacs installation on Windows. It is | |
1627 | now the same as on GNU and Unix systems. In particular, the auxiliary | |
1628 | programs, such as cmdproxy.exe and hexl.exe, are in | |
1629 | libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs | |
1630 | version), version-independent site-lisp is in share/emacs/site-lisp, | |
1631 | version-specific Lisp files are in share/emacs/VERSION/lisp and in | |
1632 | share/emacs/VERSION/site-lisp, Info docs are in share/info, and data | |
1633 | files are in share/emacs/VERSION/etc. (Emacs knows about all these | |
1634 | directories and will find the files in there automatically; there's no | |
1635 | need to set any variables due to this change.) | |

1640 | ||
1641 | The new variable `w32-unicode-filenames' controls this feature: if it | |
1642 | is t, Emacs uses Unicode APIs to pass file names to system calls, | |
1643 | which lifts the limitation of file names to the current locale. | |

1681 | If you don't pass `--with-x-toolkit' to configure, or if you use |
1682 | `--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try | |

33cb2043 GM |
1693 | ** New configure option `--enable-gcc-warnings' (for developing/debugging |

1830 | `C-c LETTER' bindings are reserved for user customizations. | |
1831 | ||
6bc66c10 | 1832 | ** Internationalization |
2f940384 | 1833 | |
f938eda9 | 1834 | *** New language environment: Persian. |
2f940384 | 1835 | |
f938eda9 CY |
1836 | *** New input method `vietnamese-vni'. |
1837 | ||
6bc66c10 | 1838 | ** Nextstep (GNUstep / Mac OS X) port |
2f940384 | 1839 | |
823b2fb6 | 1840 | *** Support for fullscreen and the frame parameter fullscreen. |

c25df26e | 1847 | |
6bc66c10 | 1848 | ** Search and Replace |
d39d3c8e | 1849 | |
f938eda9 CY |
1850 | *** Non-regexp Isearch now performs "lax" space matching. |
1851 | Each sequence of spaces in the supplied search string may match any | |
1852 | sequence of one or more whitespace characters, as specified by the | |
1853 | variable `search-whitespace-regexp'. (This variable is also used by a | |
823b2fb6 | 1854 | similar existing feature for regexp Isearch.) |
2f940384 | 1855 | |
f938eda9 CY |
1856 | *** New Isearch command `M-s SPC' toggles lax space matching. |
1857 | This applies to both ordinary and regexp Isearch. | |
2f940384 | 1858 | |
f938eda9 CY |
1859 | *** New option `replace-lax-whitespace'. |
1860 | If non-nil, `query-replace' uses flexible whitespace matching too. | |
1861 | The default is nil. | |
2f940384 | 1862 | |
b9cb2387 JL |
1863 | *** Global `M-s _' starts a symbol (identifier) incremental search, |
1864 | and `M-s _' in Isearch toggles symbol search mode. | |
1865 | `M-s c' in Isearch toggles search case-sensitivity. | |
1866 | ||
6bc66c10 | 1867 | ** Navigation commands |
48de8b12 | 1868 | |
6bc66c10 GM |
1869 | *** New binding `M-g c' for `goto-char'. |
1870 | ||
1871 | *** New binding `M-g TAB' for `move-to-column'. | |
1872 | ||
1873 | *** `M-g TAB' (`move-to-column') prompts for a column number if called | |
1874 | interactively with no prefix arg. Previously, it moved to column 1. | |
1875 | ||
1876 | ** New option `yank-handled-properties' allows processing of text | |
1877 | properties on yanked text, in ways that are more general than just | |
1878 | removing them (as is done by `yank-excluded-properties'). | |
48de8b12 | 1879 | |
48de8b12 CY |
1880 | ** New option `delete-trailing-lines' specifies whether |
1881 | M-x delete-trailing-whitespace should delete trailing lines at the end | |
1882 | of the buffer. It defaults to t. | |
1883 | ||
f938eda9 | 1884 | ** `C-u M-=' now counts lines/words/characters in the entire buffer. |
826b3235 | 1885 | |
48de8b12 CY |
1886 | ** `C-x 8 RET' is now bound to `insert-char', which is now a command. |
1887 | `ucs-insert' is now an obsolete alias for `insert-char'. | |
b2459884 | 1888 | |
48de8b12 CY |
1889 | ** The `z' key no longer has a binding in most special modes. |
1890 | It used to be bound to `kill-this-buffer', but `z' is too easy to | |
1891 | accidentally type. | |
f938eda9 | 1892 | |
6bc66c10 GM |
1893 | ** New command `C-x r M-w' (`copy-rectangle-as-kill'). |
1894 | It copies the region-rectangle as the last rectangle kill. | |
f938eda9 | 1895 | |
6bc66c10 | 1896 | ** Registers |
f938eda9 | 1897 | |
823b2fb6 | 1898 | *** `C-x r +' is now overloaded to invoke `append-to-register'. |
f938eda9 | 1899 | |
f938eda9 | 1900 | *** New option `register-separator' specifies the register containing |
823b2fb6 GM |
1901 | the text to put between collected texts for use with |
1902 | M-x append-to-register and M-x prepend-to-register. | |

2a1e2476 | 1905 | * Changes in Specialized Modes and Packages in Emacs 24.3 |
ae4969c2 | 1906 | |
6bc66c10 | 1907 | ** Common Lisp emulation (CL) |
f938eda9 | 1908 | |
89660017 | 1909 | *** CL's main entry is now (require 'cl-lib). |
823b2fb6 GM |
1910 | `cl-lib' is like the old `cl' except that it uses the namespace cleanly; |
1911 | i.e., all its definitions have the "cl-" prefix (and internal definitions | |
1912 | use the "cl--" prefix). | |
7c1898a7 | 1913 | |
823b2fb6 GM |
1914 | If `cl' provided a feature under the name `foo', then `cl-lib' |
1915 | provides it under the name `cl-foo' instead; with the exceptions of the | |
1916 | few `cl' definitions that had to use `foo*' to avoid conflicts with | |
1917 | pre-existing Elisp entities. These have been renamed to `cl-foo' | |
1918 | rather than `cl-foo*'. | |
7c1898a7 | 1919 | |
92246540 | 1920 | The old `cl' is now deprecated and is mainly just a bunch of aliases that |
823b2fb6 | 1921 | provide the old, non-prefixed names. Some exceptions are listed below: |
7c1898a7 | 1922 | |
89660017 SM |
1923 | *** `cl-flet' is not like `flet' (which is deprecated). |
1924 | Instead it obeys the behavior of Common-Lisp's `flet'. | |
e8693c96 GM |
1925 | In particular, in cl-flet function definitions are lexically scoped, |
1926 | whereas in flet the scoping is dynamic. | |
89660017 SM |
1927 | |
1928 | *** `cl-labels' is slightly different from `labels'. | |
823b2fb6 GM |
1929 | The difference is that it relies on the `lexical-binding' machinery |
1930 | (as opposed to the `lexical-let' machinery used previously) to capture | |
1931 | definitions in closures, so such closures will only work if `lexical-binding' | |
1932 | is in use. | |
89660017 | 1933 | |
f94b04fc | 1934 | *** `cl-letf' is not exactly like `letf'. |
4ddedf94 GM |
1935 | The only difference is in details that relate to some deprecated usage |
1936 | of `symbol-function' in place forms. | |
f94b04fc | 1937 | |
89660017 | 1938 | *** `progv' was rewritten to use the `let' machinery. |
823b2fb6 GM |
1939 | A side effect is that variables without corresponding values are bound |
1940 | to nil rather than being made unbound. | |
89660017 | 1941 | |
9512f820 GM |
1942 | *** The following methods of extending `setf' are obsolete |
1943 | (use features from gv.el instead): | |
1944 | `define-modify-macro' (use `gv-letplace') | |
031b2ea7 GM |
1945 | `defsetf' (use `gv-define-simple-setter' or `gv-define-setter') |
1946 | `define-setf-expander' (use `gv-define-setter' or `gv-define-expander') | |
2b4da3ff | 1947 | `get-setf-method' no longer exists (see "Incompatible Lisp Changes") |
f94b04fc | 1948 | |
6bc66c10 | 1949 | ** Diff mode |
f938eda9 | 1950 | |
6bc66c10 GM |
1951 | *** Changes are now highlighted using the same color scheme as in |
1952 | modern VCSes. Deletions are displayed in red (new faces | |
1953 | `diff-refine-removed' and `smerge-refined-removed', and new definition | |
1954 | of `diff-removed'), insertions in green (new faces `diff-refine-added' | |
1955 | and `smerge-refined-added', and new definition of `diff-added'). | |
f938eda9 | 1956 | |
6bc66c10 GM |
1957 | *** The variable `diff-use-changed-face' defines whether to use the |
1958 | face `diff-changed', or `diff-removed' and `diff-added' to highlight | |
1959 | changes in context diffs. | |
2f940384 | 1960 | |
6bc66c10 GM |
1961 | *** The new command `diff-delete-trailing-whitespace' removes trailing |
1962 | whitespace introduced by a diff. | |
f938eda9 | 1963 | |
6bc66c10 GM |
1964 | ** Ediff now uses the same color scheme as Diff mode. |
1965 | ||
1966 | ** Python mode | |
1967 | ||
1968 | A new version of python.el, which provides several new features, including: | |
1969 | per-buffer shells, better indentation, Python 3 support, and improved | |
1970 | shell-interaction compatible with iPython (and virtually any other | |
1971 | text based shell). | |
1972 | ||
1973 | *** Some user options have been replaced/renamed, including (old -> new): | |
1974 | **** python-indent -> python-indent-offset | |
1975 | **** python-guess-indent -> python-indent-guess-indent-offset | |

1980 | ||
1981 | **** `python-indent-string-contents': Strings are never indented. | |
1982 | ||
1983 | **** `python-honour-comment-indentation': | |
d5b1b1aa | 1984 | Comments are always considered as indentation markers. |
6bc66c10 GM |
1985 | |
1986 | **** `python-continuation-offset': Indentation is automatically | |
1987 | calculated in a pep8 compliant way depending on the context. | |
1988 | ||
1989 | **** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist': | |
1990 | Have no direct mapping as the shell interaction is completely different. | |
1991 | ||
1992 | **** `python-python-command', `python-jython-command': | |
1993 | Replaced by `python-shell-interpreter'. | |
1994 | ||
1995 | **** `inferior-python-filter-regexp', `python-remove-cwd-from-path', | |
1996 | `python-pdbtrack-minor-mode-string', `python-source-modes': | |
1997 | No longer relevant. | |
1998 | ||
1999 | *** Some commands have been replaced (old -> new): | |
2000 | **** python-insert-class -> python-skeleton-class | |
2001 | **** python-insert-def -> python-skeleton-def | |
2002 | **** python-insert-for -> python-skeleton-for | |
2003 | **** python-insert-if -> python-skeleton-if | |

2044 | |
2045 | ** Dired | |
2f940384 | 2046 | |
f938eda9 CY |
2047 | *** `dired-do-async-shell-command' executes each file sequentially |
2048 | if the command ends in `;' (when operating on multiple files). | |
2049 | Otherwise, it executes the command on each file in parallel. | |
2f940384 | 2050 | |
823b2fb6 GM |
2051 | *** Typing `M-n' in the minibuffer of `dired-do-chmod', `dired-do-chgrp', |
2052 | `dired-do-chown', and `dired-do-touch' yanks the attributes of the | |
f938eda9 | 2053 | file at point. |
2f940384 | 2054 | |
f938eda9 | 2055 | *** When the region is active, `m' (`dired-mark'), `u' (`dired-unmark'), |
823b2fb6 | 2056 | `DEL' (`dired-unmark-backward'), and `d' (`dired-flag-file-deletion') |
f938eda9 | 2057 | mark/unmark/flag all files in the active region. |
2f940384 | 2058 | |
88c45e34 | 2059 | *** The minibuffer default for `=' (`dired-diff') has changed. |
f938eda9 CY |
2060 | It is now the backup file for the file at point, if one exists. |
2061 | In Transient Mark mode the default is the file at the active mark. | |
2f940384 | 2062 | |
f938eda9 CY |
2063 | *** `M-=' is no longer bound to `dired-backup-diff' in Dired buffers. |

2190 | ||
2191 | *** Semantic | |
2192 | ||
2193 | **** Support for parsing #include statements inside a namespace in C/C++. | |
2194 | ||
2195 | **** Improved support for 'extern "C"' declarations in C/C++. | |
2196 | ||
2197 | **** The ability to ignore more common special C/C++ preprocessor symbols, | |
2198 | such as '__nonnull' and '__asm'. Add '__cplusplus' macro when parsing C++. | |
2199 | If available, include cdefs.h as an additional source of preprocessor symbols. | |
2200 | ||
2201 | **** Improved C/C++ function pointer parsing. | |
2202 | ||
2203 | **** In Python, support for converting imports to include file names. | |
2204 | ||
2205 | **** Ability to dynamically determine the Python load path. | |
2206 | ||
2207 | **** Support for the Python 'WITH' and 'AT' keywords. | |

2215 | **** Tag generation supports constructor/destructor settings and system | |
2216 | include differentiation. | |
2217 | ||
2218 | **** Addition of 'Framework' support: Frameworks are specified when a | |
2219 | particular kind of library (such as Android) is needed in a common language | |
2220 | mode (like Java). | |

35d98877 | 2232 | |
6bc66c10 GM |
2233 | *** Non-option variables are never matched in `customize-apropos' and |
2234 | `customize-apropos-options' (i.e., the prefix argument does nothing for | |
2235 | these commands now). | |

fc72b15c | 2241 | |
02969baf GM |
2242 | *** You can customize how to display ANSI terminal colors and styles |
2243 | by customizing the corresponding `term-color-<COLOR>', | |

ce7b18ec | 2252 | ** URL |
2f940384 | 2253 | |
ce7b18ec CY |
2254 | *** Structs made by `url-generic-parse-url' have nil `attributes' slot. |
2255 | Previously, this slot stored semicolon-separated attribute-value pairs | |
2256 | appended to some imap URLs, but this is not compatible with RFC 3986. | |
823b2fb6 | 2257 | So now the `filename' slot stores the entire path and query components, |
ce7b18ec | 2258 | and the `attributes' slot is always nil. |
2f940384 | 2259 | |
ce7b18ec CY |
2260 | *** New function `url-encode-url' for encoding a URI string. |
2261 | The `url-retrieve' function now uses this to encode its URL argument, | |
2262 | in case that is not properly encoded. | |
2263 | ||
6bc66c10 GM |
2264 | ** notifications.el supports now version 1.2 of the Notifications API. |
2265 | The function `notifications-get-capabilities' returns the supported | |
2266 | server properties. | |
f938eda9 | 2267 | |
6bc66c10 GM |
2268 | ** Flymake uses fringe bitmaps to indicate errors and warnings. |
2269 | See `flymake-fringe-indicator-position', `flymake-error-bitmap' and | |
2270 | `flymake-warning-bitmap'. | |
f938eda9 | 2271 | |
6bc66c10 GM |
2272 | ** The FFAP option `ffap-url-unwrap-remote' can now be a list of strings, |
2273 | specifying URL types that should be converted to remote file names at | |
2274 | the FFAP prompt. The default is now '("ftp"). | |
f938eda9 | 2275 | |
6bc66c10 GM |
2276 | ** New Ibuffer `derived-mode' filter, bound to `/ M'. |
2277 | The old binding for `/ M' (filter by used-mode) is now bound to `/ m'. | |
f938eda9 | 2278 | |
6bc66c10 GM |
2279 | ** New option `mouse-avoidance-banish-position' specifies where the |
2280 | `banish' mouse avoidance setting moves the mouse. | |
ce7b18ec | 2281 | |
6bc66c10 GM |
2282 | ** In Perl mode, new option `perl-indent-parens-as-block' causes non-block |
2283 | closing brackets to be aligned with the line of the opening bracket. | |
f938eda9 | 2284 | |
6bc66c10 | 2285 | ** In Proced mode, new command `proced-renice' renices marked processes. |
f938eda9 | 2286 | |
6bc66c10 GM |
2287 | ** New option `async-shell-command-buffer' specifies the buffer to use |
2288 | for a new asynchronous `shell-command' when the default output buffer | |
2289 | `*Async Shell Command*' is already in use. | |
f938eda9 | 2290 | |
6bc66c10 GM |
2291 | ** SQL mode has a new option `sql-db2-escape-newlines'. |
2292 | If non-nil, newlines sent to the command interpreter will be escaped | |
2293 | by a backslash. The default does not escape the newlines and assumes | |
2294 | that the sql statement will be terminated by a semicolon. | |
f938eda9 | 2295 | |
6bc66c10 GM |
2296 | ** New command `tabulated-list-sort', bound to `S' in Tabulated List mode |
2297 | (and modes that derive from it), sorts the column at point, or the Nth | |
2298 | column if a numeric prefix argument is given. | |
f938eda9 | 2299 | |
02969baf | 2300 | ** `which-func-modes' now defaults to t, so Which Function mode, when |
05b621a6 | 2301 | enabled, applies to all applicable major modes. |
f938eda9 | 2302 | |
6bc66c10 | 2303 | ** `winner-mode-hook' now runs when the mode is disabled, as well as when |

f938eda9 | 2305 | |
6bc66c10 GM |
2306 | ** Follow mode no longer works by using advice. |

2f940384 | 2336 | |
797e6e88 SM |
2337 | *** assoc.el |
2338 | In most cases, assoc+member+push+delq work just as well. | |

6bc66c10 GM |
2351 | ** Docstrings starting with `*' no longer indicate user options. |
2352 | Only variables defined using `defcustom' are considered user options. | |
2353 | The function `user-variable-p' is now an obsolete alias for | |
2354 | `custom-variable-p'. | |
090cf9db | 2355 | |
6bc66c10 GM |
2356 | ** The return values of `defalias', `defun' and `defmacro' have changed, |
2357 | and are now undefined. For backwards compatibility, `defun' and | |
2358 | `defmacro' currently return the name of the newly defined | |
2359 | function/macro, but this should not be relied upon. | |
090cf9db | 2360 | |
823b2fb6 GM |
2361 | ** `random' by default now returns a different random sequence in |
2362 | every Emacs run. Use `(random S)', where S is a string, to set the | |
0e23ef9d PE |
2363 | random seed to a value based on S, in order to get a repeatable |
2364 | sequence in later calls. | |
2365 | ||
d32e47af LM |
2366 | ** If the NEWTEXT arg to `replace-match' contains a substring "\?", |
2367 | that substring is inserted literally even if the LITERAL arg is | |
2368 | non-nil, instead of causing an error to be signaled. | |
2369 | ||
2cec368c MR |
2370 | ** `select-window' now always makes the window's buffer current. |
2371 | It does so even if the window was selected before. | |
2372 | ||
6bc66c10 GM |
2373 | ** The function `x-select-font' can return a font spec, instead of a |
2374 | font name as a string. Whether it returns a font spec or a font name | |
2375 | depends on the graphical library. | |
bbf908bc | 2376 | |
eeddc531 CY |
2377 | ** `face-spec-set' no longer sets frame-specific attributes when the |
2378 | third argument is a frame (that usage was obsolete since Emacs 22.2). | |
2379 | ||
6bc66c10 | 2380 | ** `set-buffer-multibyte' now signals an error in narrowed buffers. |
a59d531e | 2381 | |
ab7f1c43 GM |
2382 | ** The CL package's `get-setf-method' function no longer exists. |
2383 | Generalized variables are now part of core Emacs Lisp, and implemented | |
2384 | differently to the way cl.el used to do it. It is not possible to | |
2385 | define a compatible replacement for `get-setf-method'. See the file | |
2386 | gv.el for internal details of the new implementation. | |
2387 | ||
6bc66c10 GM |
2388 | ** The arguments of `dbus-register-signal' are no longer just strings, |
2389 | but keywords or keyword-string pairs. The old argument list will | |
2390 | still be supported for Emacs 24.x. | |
72b255c7 | 2391 | |
6bc66c10 | 2392 | ** Miscellaneous name changes |
823b2fb6 GM |
2393 | Some Lisp symbols have been renamed to correct their spelling, |
2394 | or to be more consistent with standard Emacs terminology. | |
72b255c7 | 2395 | |
72b255c7 | 2396 | *** Renamed functions |

ef24141c | 2441 | |
2ee3d7f0 | 2442 | ** CL-style generalized variables are now in core Elisp. |
f938eda9 | 2443 | `setf' is autoloaded; `push' and `pop' accept generalized variables. |
ebdbfb95 GM |
2444 | You can define your own generalized variables using `gv-define-simple-setter', |
2445 | `gv-define-setter', etc. | |
2ee3d7f0 | 2446 | |
6bc66c10 GM |
2447 | ** Emacs tries to macroexpand interpreted (non-compiled) files during load. |
2448 | This can significantly speed up execution of non-byte-compiled code, | |
2449 | but can also bump into previously unnoticed cyclic dependencies. | |
2450 | These are generally harmless: they will simply cause the macro calls | |
2451 | to be left for later expansion (as before), but will result in a | |
2452 | warning ("Eager macro-expansion skipped due to cycle") describing the cycle. | |
2453 | You may wish to restructure your code so this does not happen. | |
2454 | ||
2455 | ** New sampling-based Elisp profiler. | |
2456 | Try M-x profiler-start, do some work, and then call M-x profiler-report. | |
2457 | When finished, use M-x profiler-stop. The sampling rate can be based on | |
2458 | CPU time or memory allocations. | |
2459 | ||
500fcedc SM |
2460 | ** `defun' also accepts a (declare DECLS) form, like `defmacro'. |
2461 | The interpretation of the DECLS is determined by `defun-declarations-alist'. | |
2462 | ||
6bc66c10 GM |
2463 | ** New macros `setq-local' and `defvar-local'. |

2465 | ** Face underlining can now use a wave. | |
2f940384 | 2466 | |
6bc66c10 | 2467 | ** `read-regexp' has a new argument HISTORY; the first argument PROMPT |
cd996018 | 2468 | of `read-regexp' accepts a string ending with a colon and space, and its |
823b2fb6 | 2469 | second argument DEFAULTS can be a list of strings accessible via `M-n' |
cd996018 CY |
2470 | in the minibuffer ahead of other hard-coded useful regexp-related values. |
2471 | More commands use `read-regexp' now to read their regexp arguments. | |
2472 | ||
f938eda9 | 2473 | ** Completion |
500fcedc | 2474 | |
f938eda9 CY |
2475 | *** New function `completion-table-with-quoting' to handle completion |
2476 | in the presence of quoting, such as file completion in shell buffers. | |
f95e9344 | 2477 | |
f938eda9 CY |
2478 | *** New function `completion-table-subvert' to use an existing completion |
2479 | table, but with a different prefix. | |
2480 | ||
6bc66c10 | 2481 | ** Debugger |
f95e9344 | 2482 | |
f938eda9 CY |
2483 | *** New error type and new function `user-error'. |
2484 | These do not trigger the debugger. | |
f95e9344 | 2485 | |
57fc0fee GM |
2486 | *** New option `debugger-bury-or-kill', saying what to do with the |
2487 | debugger buffer when exiting debug. | |
45b82ad0 SM |
2488 | |
2489 | *** Set `debug-on-message' to enter the debugger when a certain | |
2490 | message is displayed in the echo area. This can be useful when trying | |
2491 | to work out which code is doing something. | |
2f940384 | 2492 | |
45b82ad0 SM |
2493 | *** New var `inhibit-debugger', automatically set to prevent accidental |
2494 | recursive invocations. | |
fa2bcf43 | 2495 | |
6bc66c10 | 2496 | ** Window handling |
2f940384 | 2497 | |
6bc66c10 GM |

6bc66c10 GM |
2501 | *** The command `fit-window-to-buffer' can adjust the frame height |
2502 | if the new option `fit-frame-to-buffer' is non-nil. | |
8e17c9ba | 2503 | |
7fe37cfc GM |
2504 | *** New macro `with-temp-buffer-window', similar to |
2505 | `with-output-to-temp-buffer'. | |
fa2bcf43 | 2506 | |
8e17c9ba MR |
2507 | *** `temp-buffer-resize-mode' no longer resizes windows that have been |
2508 | reused. | |
c5e28e39 | 2509 | |
823b2fb6 | 2510 | *** New option `switch-to-buffer-preserve-window-point' to restore a |
43bcfda6 | 2511 | window's point when switching buffers. |
7c82753d | 2512 | |
6bc66c10 GM |

2514 | specify the size of new windows created by `display-buffer'. | |
2515 | ||
2516 | *** New display action alist entry `pop-up-frame-parameters', if | |

2527 | and `display-buffer-in-previous-window'. | |
2528 | ||
2529 | *** The functions `get-lru-window', `get-mru-window' and `get-largest-window' | |
2530 | now accept a third argument to avoid choosing the selected window. | |

2f940384 | 2546 | |
ab0fa4e4 PE |
2547 | *** `current-time-string' no longer requires that its argument's year |
2548 | must be in the range 1000..9999. It now works with any year supported | |
2549 | by the underlying C implementation. | |
2f940384 | 2550 | |
f938eda9 CY |
2551 | *** `current-time' now returns extended-format time stamps |
2552 | (HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds. | |
2553 | PSEC is typically a multiple of 1000 on current machines. Other | |
823b2fb6 GM |
2554 | functions that use this format, such as `file-attributes' and |
2555 | `format-time-string', have been changed accordingly. Old-format time | |
f938eda9 | 2556 | stamps are still accepted. |
2f940384 | 2557 | |
823b2fb6 | 2558 | *** The format of timers in `timer-list' and `timer-idle-list' is now |
f938eda9 CY |
2559 | [TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS]. |
2560 | The PSECS slot is new, and uses picosecond resolution. It can be | |

2566 | ** EIEIO |
2567 | ||
2568 | *** Improved security when handling persistent objects: | |
2569 | ||
2570 | **** `eieio-persistent-read' now features optional arguments for specifying | |
2571 | the class to load, as well as a flag stating whether subclasses are allowed; | |
2572 | if provided, other classes will be rejected by the reader. For | |
2573 | compatibility with existing code, if the class is omitted only a | |
2574 | warning is issued. | |
2575 | ||
2576 | **** New specialized reader for pulling in classes and signaling errors | |
2577 | without evaluation of suspicious code. | |
2578 | ||
2579 | **** All slots that contain objects must have a :type. Slots with lists | |
2580 | of objects must use a new type predicate for a list of an object type. | |
2581 | ||
2582 | *** Support for `find-function' and similar utilities, through the addition | |
2583 | of filename support to generated symbols. | |
2584 | ||
f938eda9 | 2585 | ** Floating point functions now always return special values like NaN, |
823b2fb6 | 2586 | instead of signaling errors, if given invalid args; e.g., (log -1.0). |
f938eda9 CY |
2587 | Previously, they returned NaNs on some platforms but signaled errors |
2588 | on others. The affected functions are acos, asin, tan, exp, expt, | |
2589 | log, log10, sqrt, and mod. | |
2590 | ||
6bc66c10 | 2591 | ** New fringe bitmap `exclamation-mark'. |

9078ead6 | 2633 | |
4e98ad15 | 2634 | ** Cygwin builds can use the native MS Windows user interface. |
823b2fb6 | 2635 | Pass `--with-w32' to configure. The default remains the X11 interface. |
53a63be6 | 2636 | |
1a9c6830 | 2637 | ** Two new functions are available in Cygwin builds: |
6e9f7997 DC |
2638 | `cygwin-convert-file-name-from-windows' and |
2639 | `cygwin-convert-file-name-to-windows'. These functions allow Lisp | |
2640 | code to access the Cygwin file-name mapping machinery to convert | |
2641 | between Cygwin and Windows-native file and directory names. | |
de6e3a60 | 2642 | |
4e98ad15 | 2643 | ** When invoked with the -nw switch to run on the Windows text-mode terminal, |
1ab0c851 | 2644 | Emacs now supports `mouse-highlight', help-echo (in the echo area), and |
4e98ad15 GM |
2645 | `mouse-autoselect-window'. |
2646 | ||
1a9c6830 | 2647 | ** On MS Windows Vista and later Emacs now supports symbolic links. |
4e98ad15 | 2648 | |
823b2fb6 | 2649 | ** On MS Windows, you can pass `--without-libxml2' to configure.bat to omit |
4e98ad15 GM |
2650 | support for libxml2, even if its presence is detected. |
2651 | ||
4e98ad15 GM |
2652 | ** On Mac OS X, the Nextstep port requires OS X 10.4 or later. |
2653 | ||
823b2fb6 | 2654 | ** On Mac OS X, configure no longer automatically adds the Fink "/sw" |

eb199145 | 2663 | * Installation Changes in Emacs 24.1 |
09e18d03 | 2664 | |
31fd3586 GM |
2665 | ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
2666 | to configure. Note that other libraries used by Emacs, RSVG and GConf, | |
2667 | also depend on Gtk+. You can disable them with --without-rsvg and | |
2668 | --without-gconf. | |
338648ad | 2669 | |
31fd3586 GM |
2670 | ** Emacs can be compiled with GnuTLS support. |
2671 | This happens by default if a suitably recent version of the library is | |
2672 | found at build time. To prevent this, use the configure option | |
2673 | `--without-gnutls'. See below for GnuTLS features. | |
338648ad | 2674 | |
31fd3586 GM |
2675 | ** Emacs can be compiled with SELinux support. |
2676 | This happens by default if a suitably recent version of the library is | |
2677 | found at build time. To prevent this, use the configure option | |
2678 | `--without-selinux'. See below for SELinux features. | |
aded53ff | 2679 | |
31fd3586 GM |
2680 | ** Emacs can be compiled with ImageMagick support. |
2681 | This happens by default if a suitably recent version of the library is | |
2682 | found at build time. To prevent this, use the configure option | |
2683 | `--without-imagemagick'. See below for ImageMagick features. | |
c1f10868 | 2684 | This feature is not available for the Nextstep or MS ports. |
d9170db5 | 2685 | |
043efd56 GM |
2686 | ** Emacs can be compiled with libxml2 support. |
2687 | This happens by default if a suitably recent version of the library is | |
2688 | found at build time. To prevent this, use the configure option | |
2689 | `--without-xml2'. See below for libxml2 features. | |
2690 | ||
7d301ae6 CY |
2691 | ** By default, the installed Info and man pages are compressed. |
2692 | You can disable this by configuring --without-compress-info. | |
2693 | ||
7d301ae6 | 2694 | ** New configure option --with-wide-int. |
81eafe29 | 2695 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. |
0a768890 PE |
2696 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB |
2697 | to about 2 GiB. | |
81eafe29 | 2698 | |
7d301ae6 | 2699 | ** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost. |
31fd3586 GM |
2700 | These provide no new functionality, they just remove the need to edit |
2701 | lib-src/Makefile by hand in order to use the associated features. | |
2702 | ||
7d301ae6 | 2703 | ** New configure option --enable-use-lisp-union-type. |
31fd3586 GM |
2704 | This is only useful for Emacs developers to debug certain types of bugs. |
2705 | This is not a new feature; only the configure flag is new. | |
041d709f CY |
2706 | |
2707 | ** The standalone programs digest-doc and sorted-doc are removed. | |
2708 | Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'. | |
2709 | ||
041d709f CY |
2710 | ** The standalone program `fakemail' is removed. |
2711 | If you need it, feedmail.el provides a superset of the functionality. | |

eb199145 | 2714 | * Startup Changes in Emacs 24.1 |
4a263588 | 2715 | |
198a7a97 | 2716 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte |
adbf62ff GM |
2717 | command line arguments, and the EMACS_UNIBYTE environment variable, no |
2718 | longer have any effect. (They were declared obsolete in Emacs 23.) | |
198a7a97 | 2719 | |
66b7b0fe | 2720 | ** New command line option `--no-site-lisp' removes site-lisp directories |
1b5e5b0c GM |
2721 | from load-path. -Q now implies this. This option does not affect the |
2722 | EMACSLOADPATH environment variable (and hence has no effect for | |
c8d59ba3 | 2723 | Nextstep builds). |
66b7b0fe | 2724 | |

eb199145 | 2726 | * Changes in Emacs 24.1 |
7841339b | 2727 | |
a2a25d24 | 2728 | ** Completion |
fdeb32ec | 2729 | |
dfdb4cad CY |
2730 | *** Many packages now use the `completion-at-point' command, |
2731 | rather than implementing separate completion commands. | |
2732 | ||
de0bde62 | 2733 | *** `completion-at-point' now handles tags and semantic completion. |
dfdb4cad | 2734 | |
a2a25d24 SM |
2735 | *** Completion in a non-minibuffer now tries to detect the end of completion |
2736 | and pops down the *Completions* buffer accordingly. | |
dfdb4cad CY |
2737 | |
2738 | *** New option `completion-cycle-threshold' allows completion cycling. | |
2739 | ||
2740 | *** New option `completion-category-overrides' for overriding the | |
2c719188 | 2741 | default completion style in certain circumstances. |
dfdb4cad | 2742 | |
a2a25d24 | 2743 | *** New completion style `substring'. |
dfdb4cad CY |
2744 | |
2745 | *** Completion of buffer names uses `substring' completion by default. | |
2746 | ||
2747 | *** The option `widget-complete-field' has been removed. | |
620c53a6 | 2748 | |
6870aaef | 2749 | ** Mail changes |
dfdb4cad | 2750 | |
7d301ae6 CY |
2751 | *** The first time you try sending mail, Emacs asks for a mail method. |
2752 | This is implemented by a new default for `send-mail-function', which | |
2753 | is `sendmail-query-once'. This offers to use the smtpmail package, or | |
2754 | to use the old defaults relying on external mail facilities | |
2755 | (`sendmail-send-it' on GNU/Linux and other Unix-like systems, and | |
2756 | `mailclient-send-it' on Windows). | |
dfdb4cad | 2757 | |
e78e7e48 CY |
2758 | *** Typing `C-c m' in the buffer made by `M-x report-emacs-bug' |
2759 | transfers the report to your desktop's preferred mail client, if there | |
2760 | is one. This uses either the "xdg-email" utility, or Mac OS's "open" | |
2761 | command. | |
dfdb4cad | 2762 | |
7d301ae6 CY |
2763 | *** See Changes in Specialized Modes and Packages for SMTPmail changes |
2764 | and Mail mode changes | |
3f88cd72 | 2765 | |
041d709f | 2766 | ** Emacs server and client changes |
dfdb4cad | 2767 | |
7d301ae6 | 2768 | *** New option `server-port' specifies the port for TCP Emacs servers. |
dfdb4cad | 2769 | |
041d709f | 2770 | *** New emacsclient argument -q/--quiet suppresses some status messages. |
dfdb4cad | 2771 | |
7d301ae6 CY |
2772 | *** New emacsclient argument --frame-parameters specifies the frame |
2773 | parameters of any newly-created graphical frame. | |
dfdb4cad CY |
2774 | |
2775 | *** If emacsclient shuts down due to Emacs signaling an error, | |
2776 | its exit status is 1. | |
2777 | ||
041d709f CY |
2778 | *** New emacsclient argument --parent-id ID. |
2779 | This opens a client frame in parent X window ID, via XEmbed, similar | |
2780 | to the --parent-id argument to Emacs. | |
2781 | ||
d0ce9f8c MB |
2782 | ** Internationalization changes |
2783 | ||
d0ce9f8c | 2784 | *** Emacs now supports display and editing of bidirectional text. |
7d301ae6 CY |
2785 | Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are |
2786 | displayed in the correct visual order as expected by users of those | |
dfdb4cad CY |
2787 | scripts. The display reordering is a "full bidirectionality" class |
2788 | implementation of the Unicode Bidirectional Algorithm (UBA). Buffers | |
2789 | with no RTL text should look exactly the same as before. | |
f4b6ba46 | 2790 | |
041d709f | 2791 | **** New buffer-local variable `bidi-display-reordering'. |
7d301ae6 | 2792 | To disable display reordering in a buffer, change this to nil. |
d20e1419 | 2793 | |
041d709f CY |
2794 | **** New buffer-local variable `bidi-paragraph-direction'. |
2795 | If nil (the default), Emacs determines the base direction of each | |
dfdb4cad CY |
2796 | paragraph from its text, as specified by the UBA. Setting the value |
2797 | to `right-to-left' or `left-to-right' forces a base direction on each | |
2798 | paragraph. | |
f4b6ba46 | 2799 | |
7d301ae6 CY |
2800 | Paragraphs with right-to-left base direction are displayed starting at |
2801 | the right window edge. | |
f1816485 | 2802 | |
dfdb4cad CY |
2803 | *** Enhanced support for characters with no glyphs in available fonts, |
2804 | or, on text terminals, characters that cannot be encoded by the | |
2805 | terminal coding system. The new option `glyphless-char-display-control' | |
2806 | specifies how to display them: as a hexadecimal code in a box, a thin | |
2807 | 1-pixel space, an empty box, etc. | |
d0ce9f8c | 2808 | |
9702b7a1 GM |
2809 | *** New input methods for Farsi and Bulgarian |
2810 | (farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic). | |
041d709f | 2811 | |
939db9ac CY |
2812 | *** `nobreak-char-display' now also highlights Unicode hyphen chars |
2813 | (U+2010 and U+2011). | |
2814 | ||
7d301ae6 | 2815 | *** New Hebrew translation of the Emacs Tutorial. |
31fd3586 GM |
2816 | Type `C-u C-h t' to choose it in case your language setup doesn't |
2817 | automatically select it. | |
2818 | ||
7d301ae6 CY |
2819 | ** An Emacs Lisp package manager is now included. |
2820 | This is a convenient way to download and install additional packages, | |
2821 | from a package repository at http://elpa.gnu.org. | |
dfdb4cad | 2822 | |
7d301ae6 CY |
2823 | *** M-x list-packages shows a list of packages, which can be |
2824 | selected for installation. | |
dfdb4cad | 2825 | |
7d301ae6 | 2826 | *** New command `describe-package', bound to `C-h P'. |
dfdb4cad | 2827 | |
7d301ae6 CY |
2828 | *** By default, all installed packages are loaded automatically when |
2829 | Emacs starts up. To disable this, set `package-enable-at-startup' to | |
2830 | nil. To specify the packages to load, customize `package-load-list'. | |
16a91140 | 2831 | |
dfdb4cad CY |
2832 | ** Custom theme changes |
2833 | ||
7d301ae6 CY |
2834 | *** New command `M-x customize-themes', which provides a convenient |
2835 | interface for enabling and disabling Custom themes. | |
dfdb4cad | 2836 | |
7d301ae6 | 2837 | *** New option `custom-theme-load-path' is the load path for themes. |
dfdb4cad CY |
2838 | Emacs no longer looks for Custom themes in `load-path'. The default |
2839 | value of `custom-theme-load-path' says to look for themes in | |
2840 | `custom-theme-directory', followed by a subdirectory of | |
2841 | `data-directory' named "themes/", which contains a small selection of | |
2842 | built-in Custom themes. | |
2843 | ||
7d301ae6 CY |
2844 | *** New option `custom-safe-themes' records known-safe theme files. |
2845 | If a theme is not in this list, Emacs queries before loading it, and | |
2846 | offers to save the theme to `custom-safe-themes' automatically. By | |
2847 | default, all themes included in Emacs are treated as safe. | |
b7d65a5f | 2848 | |
7d301ae6 | 2849 | ** Improved GTK integration |
dfdb4cad | 2850 | |
7d301ae6 | 2851 | *** GTK scroll-bars are now placed on the right by default. |
dfdb4cad CY |
2852 | The function `set-scroll-bar-mode' can change this. |
2853 | ||
7d301ae6 | 2854 | *** GTK tool bars can have just text, just images or images and text. |
dfdb4cad CY |
2855 | Customize `tool-bar-style' to choose the style. On a Gnome desktop, |
2856 | the default is taken from desktop settings. | |
2857 | ||
2858 | *** GTK tool bars can be placed on any edge of the frame. | |
7d301ae6 CY |
2859 | The frame-parameter tool-bar-position controls this. It takes the |
2860 | values top, left, right or bottom. The Options => Show/Hide menu has | |
2861 | entries for this. | |
dfdb4cad | 2862 | |
7d301ae6 CY |
2863 | *** The default colors for selected text (the `region' face) are taken |
2864 | from the GTK theme when Emacs is built with GTK. | |
dfdb4cad | 2865 | |
7d301ae6 CY |
2866 | *** Emacs uses GTK tooltips by default if built with GTK. |
2867 | You can disable this by changing `x-gtk-use-system-tooltips' to nil. | |

dfdb4cad CY |
2869 | ** Graphical interface changes |
2870 | ||
2871 | *** On graphical displays, the mode-line no longer ends in dashes. | |
2872 | Also, the first dash (which does not indicate anything) is just | |
2873 | displayed as a space. | |
2874 | ||
2875 | *** `menu-bar-select-buffer-function' lets you choose another operation | |
2876 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. | |
2877 | ||
2878 | *** Lucid menus and dialogs can display antialiased fonts if Emacs is | |
2879 | built with Xft. These fonts can be set via X resources, for example: | |
2880 | Emacs.pane.menubar.font: Courier-12 | |
2881 | ||
7d301ae6 | 2882 | ** Exiting changes |
dfdb4cad | 2883 | |
7d301ae6 | 2884 | *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP, |
dfdb4cad CY |
2885 | or if it receives a SIGINT signal in batch mode. |
2886 | ||
7d301ae6 CY |
2887 | *** `kill-emacs-hook' is now also run in batch mode. |
2888 | Third-party code which adds to `kill-emacs-hook' should check if they | |
2889 | do the right thing in batch mode. | |
9c524fcb | 2890 | |
041d709f | 2891 | ** Scrolling changes |
dfdb4cad | 2892 | |
041d709f | 2893 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' |
0a19a6f8 | 2894 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
7d301ae6 | 2895 | of buffer at first key-press (instead they move to top/bottom of buffer) |
550f41cd | 2896 | when `scroll-error-top-bottom' is non-nil. |
dfdb4cad CY |
2897 | |
2898 | *** New option `scroll-error-top-bottom' (see above). | |
2899 | ||
041d709f | 2900 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' |
5a97d2da | 2901 | scroll a line instead of full screen. |
dfdb4cad | 2902 | |
041d709f | 2903 | *** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 2904 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
dfdb4cad | 2905 | |
041d709f | 2906 | *** If you customize `scroll-conservatively' to a value greater than 100, |
d0f69533 EZ |
2907 | Emacs will never recenter point in the window when it scrolls due to |
2908 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | |
2909 | Previously, you needed to use `most-positive-fixnum' as the value of | |
2910 | `scroll-conservatively' to achieve the same effect. | |
dfdb4cad | 2911 | |
7d301ae6 | 2912 | *** "Aggressive" scrolling now honors the scroll margins. |
d0f69533 EZ |
2913 | If you customize `scroll-up-aggressively' or |
2914 | `scroll-down-aggressively' and move point off the window, Emacs now | |
2915 | scrolls the window so as to avoid positioning point inside the scroll | |
2916 | margin. | |
2917 | ||
7d301ae6 CY |
2918 | ** Basic SELinux support has been added. |
2919 | This requires Emacs to be linked with libselinux at build time. | |
f1a5d776 | 2920 | |
dfdb4cad CY |
2921 | *** Emacs preserves the SELinux file context when backing up. |
2922 | Also, the function `copy-file' has an extra optional argument for | |
2923 | preserving SELinux context, and the return value of `backup-buffer' | |
2924 | now includes the SELinux context. | |
f0bf7c8e | 2925 | |
dfdb4cad | 2926 | *** New functions `file-selinux-context' and `set-file-selinux-context' |
7d301ae6 | 2927 | get and set the SELinux context of a file. |
44198b6e | 2928 | |
7d301ae6 | 2929 | ** Trash changes |
dfdb4cad | 2930 | |
7d301ae6 CY |
2931 | *** `delete-by-moving-to-trash' now only affects commands that specify |
2932 | trashing. This avoids inadvertently trashing temporary files. | |
dfdb4cad | 2933 | |
7d301ae6 CY |
2934 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
2935 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
278f6845 | 2936 | |
041d709f | 2937 | ** File- and directory-local variable changes |
dfdb4cad | 2938 | |
041d709f CY |
2939 | *** You can stop directory local vars from applying to subdirectories. |
2940 | Add an element (subdirs . nil) to the alist portion of any variables | |
2941 | settings to indicate that the section should not apply to | |
2942 | subdirectories. | |
dfdb4cad | 2943 | |
041d709f CY |
2944 | *** Directory local variables can apply to some file-less buffers. |
2945 | Affected modes include dired, vc-dir, and log-edit. For example, | |
2946 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will | |
2947 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call | |
2948 | `hack-dir-local-variables-non-file-buffer' to support this. | |
dfdb4cad | 2949 | |
041d709f CY |
2950 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. |
2951 | Instead, use "eval: (minor-mode 1)". | |
c136e5cd | 2952 | |
7b447e9b GM |
2953 | *** The variable `inhibit-first-line-modes-regexps' has been renamed |
2954 | to `inhibit-local-variables-regexps'. As the name suggests, it now | |
dfdb4cad CY |
2955 | applies to ALL file local variables, not just -*- lines. The |
2956 | associated `inhibit-first-line-modes-suffixes' has been renamed in the | |
2957 | corresponding way. | |
5d907d6c | 2958 | |
0a2132ba CY |
2959 | ** Window changes |
2960 | ||
91b65361 CY |
2961 | *** The `quit-window' command now restores the last buffer displayed |
2962 | in the quitted window. | |
2963 | ||
0a2132ba CY |
2964 | *** Resizing an Emacs frame now preserves proportional window sizes, |
2965 | modulo restrictions like window minimum sizes and fixed-size windows. | |
2966 | ||
2967 | *** The behavior of `display-buffer' is now customizable in detail. | |
dfdb4cad | 2968 | |
0a2132ba CY |
2969 | **** New option `display-buffer-base-action' specifies a list of |
2970 | user-determined display "actions" (functions and optional arguments | |
2971 | for choosing the displaying window). | |
2972 | ||
2973 | This takes precedence over the default display action, which is | |
2974 | specified by `display-buffer-fallback-action'. | |
2975 | ||
2976 | **** New option `display-buffer-alist' maps buffer name regexps to | |
2977 | display actions, taking precedence over `display-buffer-base-action'. | |
2978 | ||
a0c2d0ae MR |
2979 | *** New option `window-combination-limit'. |
2980 | The new option `window-combination-limit' allows to return the space | |
2981 | obtained for resizing or creating a window more reliably to the window | |
2982 | from which such space was obtained. | |
0a2132ba | 2983 | |
a0c2d0ae MR |
2984 | *** New option `window-combination-resize'. |
2985 | The new option `window-combination-resize' allows to split a window that | |
2986 | otherwise cannot be split because it's too small by stealing space from | |
2987 | other windows in the same combination. Subsequent resizing or deletion | |
2988 | of the window will resize all windows in the same combination as well. | |
0a2132ba | 2989 | |
91b65361 CY |
2990 | *** New option `frame-auto-hide-function' lets you choose between |
2991 | iconifying or deleting a frame when burying a buffer in a dedicated | |
2992 | frame, or quitting a window showing a buffer in a frame of its own. | |
2993 | ||
0a2132ba | 2994 | *** New commands `maximize-window' and `minimize-window'. |
53964682 | 2995 | These maximize and minimize the size of a window within its frame. |
0a2132ba | 2996 | |
0a2132ba CY |
2997 | *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'. |
2998 | These functions allow to navigate through the live buffers that have | |
2999 | been shown in a specific window. | |
3000 | ||
7d301ae6 | 3001 | ** Minibuffer changes |
dfdb4cad | 3002 | |
7d301ae6 | 3003 | *** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. |
104dc9c6 GM |
3004 | This is handy for minibuffer-only frames, and is also used for the feature |
3005 | where mouse-1 pops up *Messages*"', which can now easily be changed. | |
041d709f | 3006 | |
7d301ae6 | 3007 | *** Minibuffers set `truncate-lines' to nil. |
f66eca26 | 3008 | If you want to change the value to something else, you could use |
7d301ae6 CY |
3009 | for example `minibuffer-setup-hook'. |
3010 | ||
7d301ae6 CY |
3011 | ** `auto-mode-case-fold' is now enabled by default. |
3012 | ||
7d301ae6 | 3013 | ** `backup-by-copying-when-mismatch' now defaults to t. |
f66eca26 | 3014 | |
dfdb4cad CY |
3015 | ** New basic faces `error', `warning', `success'. |
3016 | These are used to highlight text indicating failure, caution or | |
3017 | successful operation. | |
3018 | ||
3019 | ** New option `list-colors-sort' defines the color sort order | |
3020 | for `list-colors-display'. | |
3021 | ||
3022 | ** The variable `focus-follows-mouse' now always defaults to nil. | |

b350bdf2 | 3026 | |
892777ba | 3027 | ** Search changes |
dfdb4cad CY |
3028 | |
3029 | *** C-y in Isearch is now bound to `isearch-yank-kill', instead of | |
3030 | `isearch-yank-line'. | |
3031 | ||
3032 | *** M-y in Isearch is now bound to `isearch-yank-pop', instead of | |
3033 | `isearch-yank-kill'. | |
3034 | ||
3035 | *** M-s C-e in Isearch is now bound to `isearch-yank-line'. | |
3036 | ||
b2b0776e | 3037 | ** New commands `count-words-region' and `count-words'. |
dfdb4cad | 3038 | |
10607bea CY |
3039 | *** M-= is bound to `count-words-region', not `count-lines-region'. |
3040 | The `count-words-region' command, when called interactively, reports | |
3041 | the number of lines, words, and characters in the region. It is a | |
3042 | superset of the old `count-lines-region', which is now an obsolete | |
3043 | alias for it. | |
ea4f7750 | 3044 | |
ec9da840 | 3045 | ** The command `just-one-space' (M-SPC), if given a negative argument, |
1c708c1a CY |
3046 | also deletes newlines around point. |
3047 | ||
b9229673 | 3048 | ** Deletion changes |
dfdb4cad | 3049 | |
b9229673 | 3050 | *** New option `delete-active-region'. |
ddb54206 | 3051 | If non-nil, [delete] and DEL delete the region if it is active and no |
dfdb4cad | 3052 | prefix argument is given. If set to `kill', those commands kill |
ddb54206 | 3053 | instead. |
dfdb4cad | 3054 | |
59ee0542 | 3055 | *** New command `delete-forward-char', bound to [delete]. |
42d9cffa CY |
3056 | This is meant for interactive use, and obeys `delete-active-region'. |
3057 | The command `delete-char' does not obey `delete-active-region'. | |
dfdb4cad | 3058 | |
b9229673 CY |
3059 | *** `delete-backward-char' is now a Lisp function. |
3060 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
7d301ae6 CY |
3061 | However, the byte compiler now warns if it is called from Lisp; Lisp |
3062 | callers should use delete-char with a negative argument instead. | |
dfdb4cad | 3063 | |
b9229673 CY |
3064 | *** The option `mouse-region-delete-keys' has been deleted. |
3065 | ||
f9d71b42 CY |
3066 | ** Selection changes. |
3067 | ||
7d301ae6 CY |
3068 | The default handling of clipboard and primary selections has been |
3069 | changed to conform with modern X applications. In short, most | |
3070 | commands for killing and yanking text now use the clipboard, while | |
3071 | mouse commands use the primary selection. | |
b1ab31ae CY |
3072 | |
3073 | In the following, we provide a list of these changes, followed by a | |
3074 | list of steps to get the old behavior back if you prefer that. | |
3075 | ||
b1ab31ae CY |
3076 | *** `select-active-regions' now defaults to t. |
3077 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
963578d3 | 3078 | the kill ring. The selected text is put in the primary selection, if |
b1ab31ae CY |
3079 | the system possesses a separate primary selection facility (e.g. X). |
3080 | ||
3081 | **** `select-active-regions' also accepts a new value, `only'. | |
3082 | This means to only set the primary selection for temporarily active | |
3083 | regions (usually made by mouse-dragging or shift-selection); | |
3084 | "ordinary" active regions, such as those made with C-SPC followed by | |
3085 | point motion, do not alter the primary selection. | |
3086 | ||
963578d3 CY |
3087 | **** `mouse-drag-copy-region' now defaults to nil. |
3088 | ||
b1ab31ae CY |
3089 | *** mouse-2 is now bound to `mouse-yank-primary'. |
3090 | This pastes from the primary selection, ignoring the kill-ring. | |
3091 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
dfdb4cad | 3092 | |
b1ab31ae | 3093 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
dfdb4cad | 3094 | |
b1ab31ae CY |
3095 | *** `x-select-enable-primary' now defaults to nil. |
3096 | Thus, commands that kill text or copy it to the kill-ring (such as | |
3097 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
3098 | ||
3099 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now | |
dfdb4cad | 3100 | exactly equivalent to M-w, C-w, and C-y respectively. |
b1ab31ae CY |
3101 | |
3102 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already | |
3103 | non-nil by default, as Windows does not support the primary selection | |
3104 | between applications. | |
3105 | ||
3106 | *** To return to the previous behavior, do the following: | |
dfdb4cad | 3107 | |
104c2fe9 | 3108 | **** Change `select-active-regions' to nil. |
b1ab31ae CY |
3109 | **** Change `mouse-drag-copy-region' to t. |
3110 | **** Change `x-select-enable-primary' to t (on X only). | |
3111 | **** Change `x-select-enable-clipboard' to nil. | |
3112 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 3113 | |
084e6df3 | 3114 | *** Support for X cut buffers has been removed. |
dfdb4cad | 3115 | |
3fd50d5c CY |
3116 | *** X clipboard managers are now supported. |
3117 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. | |
4b80f674 | 3118 | |
dfdb4cad CY |
3119 | ** New command `C-x r N' (`rectangle-number-lines') numbers the lines |
3120 | in the current rectangle. With a prefix argument, this prompts for a | |
3121 | number to count from and for a format string. | |
99f053cf | 3122 | |
7d301ae6 | 3123 | ** `redisplay-dont-pause' now defaults to t. |
6bf7006f EZ |
3124 | This makes Emacs feel more responsive to editing commands that arrive |
3125 | at high rate, e.g. if you lean on some key, because stopping redisplay | |
3126 | in the middle (when this variable is nil) forces more expensive | |
3127 | updates later on, and Emacs appears to be unable to keep up. | |
3128 | ||
e70b5064 CY |
3129 | ** The behavior of <TAB> for active regions in Text mode has changed. |
3130 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | |
3131 | when the region is active causes Emacs to indent all the lines in the | |
3132 | region, aligning them with the line previous to the first line in the | |
3133 | region (or with the left margin if there is no previous line). | |
3134 | ||
dfdb4cad CY |
3135 | ** When `occur' is called with a prefix argument, matching strings are |
3136 | collected into the `*Occur*' buffer without line numbers. If there | |
3137 | are parenthesized subexpressions in the specified regexp, `occur' | |
3138 | reads replacement text that may contain \\& and \\N whose convention | |
3139 | follows `replace-match'. | |

7d301ae6 CY |
3163 | *** The default browser used by the package is now the "xdg-open" program, |

3182 | ||
cf16af42 GM |
3183 | ** Calendar, Diary, and Appt |
3184 | ||
7d301ae6 | 3185 | *** Diary entries can contain non-printing "comments". |
548d0a63 GM |
3186 | See the variable `diary-comment-start'. |
3187 | ||
5006e634 GM |

3191 | *** The function specified by `appt-disp-window-function' may be passed |
3192 | lists of arguments if multiple appointments are due at similar times. | |
3193 | If you are using a custom function for this, you should update it. | |

7454f200 GM |

7d301ae6 CY |
3200 | *** The obsolete (since Emacs 22.1) method of enabling the appt |

dfdb4cad | 3218 | *** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes. |
551b046f AM |
3219 | Thus C-M-a will, by default, go to the beginning of the immediate function, |
3220 | not the top level. | |
3221 | ||
dfdb4cad | 3222 | *** "Macros with semicolons" can be registered for correct indentation. |
551b046f AM |
3223 | Where such a macro ends a line (no semicolon) the next statement is no longer |
3224 | parsed as a statement continuation. | |
3225 | ||
dfdb4cad | 3226 | ** Comint and modes derived from it use the standard completion code. |
041d709f CY |
3227 | |
3228 | ** Compilation mode | |
dfdb4cad | 3229 | |
7d301ae6 | 3230 | *** Compilation mode can be used without Font Lock mode. |
041d709f CY |
3231 | `compilation-parse-errors-function' is now obsolete. |
3232 | ||
dfdb4cad | 3233 | *** New variable `compilation-filter-start', which is bound while |
7d301ae6 CY |
3234 | `compilation-filter-hook' runs. It records the start position of the |
3235 | text inserted by `compilation-filter'. | |
041d709f | 3236 | |
47a6a35f GM |
3237 | *** `compilation-error-screen-columns' and `compilation-first-column' |
3238 | are obeyed in the editing buffer. So programming language modes can | |
7d301ae6 CY |
3239 | set them, whereas previously only the value in the *Compilation* |
3240 | buffer was used. | |
1dce7193 | 3241 | |
52834b6b CY |
3242 | ** Customize |
3243 | ||
3244 | *** Customize buffers now contain a search field. | |
3245 | The search is performed using `customize-apropos'. | |
7d301ae6 | 3246 | To turn off the search field, set `custom-search-field' to nil. |
52834b6b | 3247 | |
8d5dd370 | 3248 | *** Options in customize group buffers start out hidden if not customized. |
52834b6b CY |
3249 | Use the arrow to the left of the option name to toggle visibility. |
3250 | ||
3251 | *** custom-buffer-sort-alphabetically now defaults to t. | |
3252 | ||
3253 | *** The color widget now has a "Choose" button, which allows you to | |
7d301ae6 | 3254 | choose a color via `list-colors-display'. |
52834b6b | 3255 | |
041d709f CY |
3256 | ** D-Bus |
3257 | ||
5da3be7f GM |
3258 | *** It is now possible to access buses other than the default system |
3259 | or session bus. | |
041d709f | 3260 | |
7d301ae6 | 3261 | *** The `dbus-register-method' and `dbus-register-property' functions |
5da3be7f | 3262 | optionally do not register names. |
041d709f | 3263 | |
7d301ae6 | 3264 | *** The new function `dbus-register-service' registers a known service |
dfdb4cad | 3265 | name on a D-Bus without also registering a property or a method. |
041d709f | 3266 | |
f5d6548a | 3267 | ** Dired-x |
425a25f1 | 3268 | |
7d301ae6 CY |
3269 | *** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'), |
3270 | if called with a prefix argument, read a file name from the minibuffer | |
3271 | instead of using the current buffer. | |
f5d6548a | 3272 | |
7d301ae6 | 3273 | *** The "dired local variables" feature of Dired-x is obsolete. |
817b48a7 | 3274 | The standard directory local variables feature replaces it. |
8117868f | 3275 | |
041d709f | 3276 | ** ERC changes |
7492acc9 | 3277 | |
c4077254 GM |
3278 | *** New options `erc-autojoin-timing' and `erc-autojoin-delay', |
3279 | controlling attempts to autojoin a channel. | |
041d709f CY |
3280 | |
3281 | *** New variable `erc-coding-system-precedence': If we use `undecided' | |
3282 | as the server coding system, this variable will then be consulted. | |
3283 | The default is to decode strings that can be decoded as utf-8 as | |
3284 | utf-8, and do the normal `undecided' decoding for the rest. | |
7492acc9 | 3285 | |
041d709f | 3286 | ** Eshell changes |
7492acc9 | 3287 | |
05f77e38 GM |
3288 | *** The default value of `eshell-directory-name' has changed |
3289 | to be an "eshell" directory in `user-emacs-directory'. | |
3290 | The old "~/.eshell/" directory is still used if it exists, though. | |
041d709f CY |
3291 | |
3292 | ** gdb-mi | |
dfdb4cad CY |
3293 | |
3294 | *** The M-x gdb command now uses the GDB Machine Interface protocol. | |
05f77e38 GM |
3295 | It now supports multithread non-stop debugging and simultaneous |
3296 | debugging of several threads. | |
7492acc9 | 3297 | |
18af70d0 CY |
3298 | ** Image mode |
3299 | ||
05f77e38 GM |
3300 | *** RET (`image-toggle-animation') toggles animation, if applicable. |
3301 | Animation plays once, unless the option `image-animate-loop' is non-nil. | |
18af70d0 | 3302 | |
041d709f | 3303 | ** Info |
723ee192 | 3304 | |
7d301ae6 | 3305 | *** New command M-x info-display-manual displays a named Info manual. |
2ebc3b94 GM |
3306 | If that manual is already visited in some Info buffer, it displays |
3307 | that buffer. (This is handy if you have many manuals in many *info* | |
3308 | buffers, and don't remember the name of the buffer visiting the manual | |
3309 | you want to consult.) Otherwise, it loads and displays the manual. | |
691cf4a0 | 3310 | |
24ea72d3 EZ |
3311 | *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'. |
3312 | This is for compatibility with the stand-alone Info reader program, | |
3313 | and also because `Info-edit' is a rarely used command that is disabled | |
3314 | by default. | |
3315 | ||
7d301ae6 | 3316 | ** Mail mode changes (not Message mode) |
dfdb4cad | 3317 | |
7d301ae6 | 3318 | *** New command M-x mail-add-attachment for adding MIME attachments |
7d301ae6 | 3319 | |
dfdb4cad CY |
3320 | *** The command M-x mail-attach-file was renamed to M-x mail-insert-file. |
3321 | (Its name is misleading, since it has nothing to do with MIME | |
3322 | attachments.) The old name is now an obsolete alias to the new name. | |
3323 | ||
f2c3a9eb | 3324 | ** MH-E has been updated to MH-E version 8.3.1. |
041d709f | 3325 | See MH-E-NEWS for details. |
37221432 | 3326 | |
041d709f | 3327 | ** Modula-2 mode provides auto-indentation. |
37221432 | 3328 | |
041d709f | 3329 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
3c3d4f5b | 3330 | |
5d1ac394 | 3331 | ** nXML mode no longer binds C-RET to `nxml-complete'. |
dfdb4cad CY |
3332 | Completion is now performed via `completion-at-point', bound to C-M-i |
3333 | or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the | |
3334 | default), this performs tag completion. | |
5d1ac394 | 3335 | |
f2c3a9eb CY |
3336 | ** Org mode has been updated to version 7.8.09. |
3337 | See ORG-NEWS for details. | |
3338 | ||
041d709f | 3339 | ** Prolog mode has been completely revamped, with lots of additional |
7d301ae6 CY |
3340 | functionality such as more intelligent indentation, electricity, |
3341 | support for more variants, including Mercury, and a lot more. | |
041d709f CY |
3342 | |
3343 | ** Rmail | |
3344 | ||
3345 | *** The command `rmail-epa-decrypt' decrypts OpenPGP data | |
3346 | in the Rmail incoming message. | |
3347 | ||
50419064 GM |
3348 | *** The variable `rmail-message-filter' no longer has any effect. |
3349 | This change was made in Emacs 23.1 but was not advertised at the time. | |
3350 | Try using `rmail-show-message-hook' instead. | |
3351 | ||
717a1362 | 3352 | ** Shell mode |
dfdb4cad CY |
3353 | |
3354 | *** M-x shell prompts for the shell path name if the default directory | |
3355 | is a remote file name and neither the environment variable $ESHELL nor | |
3356 | the variable `explicit-shell-file-name' is set. | |
3357 | ||
3358 | *** TAB is now bound to the standard `completion-at-point' command, | |
3359 | which now implements the pcomplete rules for shell command completion. | |
717a1362 | 3360 | |
7d301ae6 CY |
3361 | ** SMTPmail |
3362 | ||
dfdb4cad | 3363 | *** SMTPmail now uses encrypted connections (via STARTTLS) by default |
7d301ae6 CY |
3364 | if the mail server supports them. This uses either built-in GnuTLS |
3365 | support, or the starttls.el library. Customize `smtpmail-stream-type' | |
3366 | to change this. | |
3367 | ||
7d301ae6 CY |
3368 | *** The variable `smtpmail-auth-credentials' has been removed. |
3369 | By default, the information is now stored in the file ~/.authinfo. | |
dfdb4cad CY |
3370 | This was the default value of smtpmail-auth-credentials. If you had |
3371 | customized smtpmail-auth-credentials to a list of user names and | |
3372 | passwords, those settings are not used. During your first connection | |
3373 | to the smtp server, Emacs will prompt for the user name and password, | |
3374 | and offer to save them to ~/.authinfo. Or you can manually copy the | |
3375 | credentials to ~/.authinfo. For example, if you had | |
7d301ae6 CY |
3376 | |
3377 | (setq smtpmail-auth-credentials | |
3378 | '(("mail.example.org" 25 "jim" "s!cret"))) | |
3379 | ||
3380 | then the equivalent line in ~/.authinfo would be | |
3381 | ||
3382 | machine mail.example.org port 25 login jim password s!cret | |
3383 | ||
3384 | See the auth-source manual for more information, e.g. on encrypting | |
3385 | the credentials file. | |
3386 | ||
7d301ae6 | 3387 | *** The variable `smtpmail-starttls-credentials' has been removed. |
dfdb4cad | 3388 | If you had that set, you need to put |
7d301ae6 CY |
3389 | |
3390 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert" | |
3391 | ||
3392 | in your ~/.authinfo file instead. | |
3393 | ||
8ce192e3 LI |
3394 | *** SMTPmail defaults to using the address in the From: header as the |
3395 | SMTP MAIL FROM envelope. To override this, set `mail-envelope-from' | |
3396 | to the address you wish to use instead. | |
3397 | ||
34e8a2da | 3398 | ** SQL mode |
041d709f | 3399 | |
34e8a2da GM |
3400 | *** New options `sql-port', `sql-connection-alist', `sql-send-terminator', |
3401 | and `sql-oracle-scan-on'. | |
041d709f | 3402 | |
dfdb4cad | 3403 | *** New options controlling prompting for login parameters. |
34e8a2da GM |
3404 | Each supported product has a custom variable `sql-*-login-params', |
3405 | which is a list of the parameters to be prompted for before a | |
3406 | connection is established. | |
041d709f CY |
3407 | |
3408 | *** The command `sql-product-interactive' now takes a prefix argument, | |
34e8a2da | 3409 | which causes it to prompt for an SQL product. |
041d709f | 3410 | |
34e8a2da | 3411 | *** Product-specific SQL interactive commands now take prefix arguments. |
041d709f CY |
3412 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), |
3413 | given a prefix argument, prompt for a name for the SQL interactive | |
3414 | buffer. This reduces the need for calling `sql-rename-buffer'. | |
3415 | ||
3416 | *** SQL interactive modes suppress command continuation prompts, and | |
3417 | replace tabs with spaces. The first change impacts multiple line SQL | |
3418 | statements entered with C-j between each line, statements yanked into | |
3419 | the buffer and statements sent with `sql-send-*' functions. The | |
34e8a2da GM |
3420 | second prevents the MySQL and Postgres interpreters from listing |
3421 | object name completions when sent text via `sql-send-*' functions. | |
041d709f CY |
3422 | |
3423 | *** New command `sql-connect' starts a predefined SQLi session, | |
3424 | using the login parameters from `sql-connection-alist'. | |
3425 | ||
3426 | *** New "Save Connection" menu item in SQLi buffers. | |
3427 | This gathers the login params specified for the SQLi session, if it | |
3428 | was not started by a connection, and saves them as a new connection. | |
3429 | ||
34e8a2da GM |
3430 | *** New commands for listing database objects and details: |
3431 | sql-list-all and sql-list-table. | |
041d709f CY |
3432 | |
3433 | *** An API for manipulating SQL product definitions has been added. | |
3434 | ||
3435 | ** TeX modes | |
3436 | ||
3437 | *** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. | |
412b9ee5 | 3438 | |
459bba37 | 3439 | ** Tramp |
dfdb4cad | 3440 | |
7d301ae6 | 3441 | *** New inline access method "ksu" (kerberized su). |
dfdb4cad | 3442 | |
459bba37 | 3443 | *** The following access methods are discontinued: "ssh1_old", |
ea843702 | 3444 | "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish". |
dfdb4cad | 3445 | |
b011fbfe GM |
3446 | *** The user option `remote-file-name-inhibit-cache' controls whether |
3447 | remote file attributes are cached for better performance. | |
dfdb4cad | 3448 | |
58f74fe4 MA |
3449 | *** The option `ange-ftp-binary-file-name-regexp' has changed its |
3450 | default value to "". | |
dfdb4cad | 3451 | |
7d301ae6 CY |
3452 | *** Handlers for `file-selinux-context' and `set-file-selinux-context' |
3453 | for remote machines which support SELinux. | |
58f74fe4 | 3454 | |
dfdb4cad | 3455 | ** New function `url-queue-retrieve', which behaves like url-retrieve, |
a48ec60c GM |
3456 | but with limits (`url-queue-parallel-processes', `url-queue-timeout') on |
3457 | the degree of parallelism. | |
177549d0 | 3458 | |
0c32ce32 CY |
3459 | ** VC and related modes |
3460 | ||
3461 | *** Support for pulling on distributed version control systems. | |
7d301ae6 CY |
3462 | The command C-x v + (`vc-pull') runs a "pull" operation, if it is |
3463 | supported (currently with Bzr, Git, and Mercurial), to update the | |
3464 | current branch and working tree. A prefix argument means to prompt | |
3465 | the user for specifics, e.g. a pull location. | |
0c32ce32 | 3466 | |
dab3703d | 3467 | *** `vc-update' is now an alias for `vc-pull'. |
0c32ce32 CY |
3468 | |
3469 | *** Support for merging on distributed version control systems. | |
7d301ae6 CY |
3470 | The command C-x v m (`vc-merge') now runs a "merge" operation, if it |
3471 | is supported (currently with Bzr, Git, and Mercurial), to merge | |
3472 | changes from another branch into the current one. It prompts for | |
3473 | specifics, e.g. a merge source. | |
0c32ce32 | 3474 | |
2afef60a | 3475 | *** New option `vc-revert-show-diff' controls whether `vc-revert' |
bbe43420 | 3476 | shows a diff while querying the user. It defaults to t. |
2afef60a | 3477 | |
d4eb88c7 CY |
3478 | *** Log entries in some Log View buffers can be toggled to display a |
3479 | longer description by typing RET (log-view-toggle-entry-display). | |
dab3703d GM |
3480 | This is currently supported for Bzr, Git, and Mercurial (to support |
3481 | another backend, define a `log-view-expanded-log-entry-function'). | |
7d301ae6 | 3482 | In the Log View buffers made by C-x v L (`vc-print-root-log'), you can |
d4eb88c7 CY |
3483 | use this to display the full log entry for the revision at point. |
3484 | ||
1c6c854e CS |
3485 | *** New command `vc-ediff' allows visual comparison of two revisions |
3486 | of a file similar to `vc-diff', but using ediff backend. | |
3487 | ||
86c60681 CY |
3488 | *** The option `vc-initial-comment' was removed in Emacs 23.2, but |
3489 | this was not advertised at the time. | |
3490 | ||
86c60681 CY |
3491 | *** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'. |
3492 | Since Emacs 23, it has done the same thing as `toggle-read-only', but | |
80c6d77f GM |
3493 | this was not advertised at the time. |
3494 | ||
041d709f CY |
3495 | ** Obsolete modes |

23d70505 GM |
3500 | |
3501 | *** partial-completion-mode (complete.el) is obsolete. | |
041d709f CY |

3504 | (setq completion-pcm-complete-word-inserts-delimiters t) | |
3505 | ||
23d70505 GM |
3506 | *** pc-mode.el is obsolete (CUA mode is much more comprehensive). |

c6ad2a4e | 3520 | Its functions and variables have been similarly renamed. |
05f77e38 | 3521 | |
dfdb4cad | 3522 | *** In `ido-file-completion-map', C-v is no longer bound to `ido-toggle-vc'. |

7d301ae6 CY |
3570 | The previous version has been moved to obsolete/old-emacs-lock.el. |
3571 | Now, there is a proper minor mode `emacs-lock-mode'. Protection | |
3572 | against exiting Emacs and killing the buffer can be set separately. | |
3573 | The mechanism for automatically turning off protection for buffers | |
3574 | with dead inferior processes has been generalized. | |

6dfcbe31 | 3578 | |
7d301ae6 CY |
3579 | ** Passing a nil argument to a minor mode function call now ENABLES |
3580 | the minor mode unconditionally. This is so that you can write e.g. | |
3581 | ||
dfdb4cad | 3582 | (add-hook 'text-mode-hook 'foo-mode) |
7d301ae6 | 3583 | |
dfdb4cad CY |
3584 | to enable foo-mode in Text mode buffers, removing the need for |
3585 | `turn-on-foo-mode' style functions. This affects all mode commands | |
3586 | defined by `define-minor-mode'. If called interactively, the mode | |
3587 | command still toggles the minor mode. | |
7d301ae6 | 3588 | |
d268b4fe CY |
3589 | ** The return value of `backup-buffer' has changed. |
3590 | It is now a list of three elements, where the second element is a list | |
3591 | describing the original file's SELinux context. If Emacs or the | |
f003f294 | 3592 | system lacks SELinux support, the context list is (nil nil nil nil). |
7d301ae6 | 3593 | See "Basic SELinux support" above, under "Changes in Emacs 24.1". |
d268b4fe | 3594 | |
dfdb4cad CY |
3595 | ** `char-direction-table' and the `char-direction' function were deleted. |
3596 | They were buggy and inferior to the new support of bidirectional | |
3597 | editing introduced in Emacs 24. If you need the bidirectional | |
3598 | properties of a character, use `get-char-code-property' with the last | |
3599 | argument `bidi-class'. | |
fa6996bc | 3600 | |
470d996d TV |
3601 | ** `copy-directory' now copies the source directory as a subdirectory |
3602 | of the target directory, if the latter is an existing directory. The | |
3603 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy | |
3604 | the contents directly into a pre-existing target directory. | |
3605 | ||
9173a8fb CY |
3606 | ** For mouse click input events in the text area, the Y pixel |
3607 | coordinate in the POSITION list now counts from the top of the text | |
3608 | area, excluding any header line. Previously, it counted from the top | |
3609 | of the header line. | |
3610 | ||
7d301ae6 CY |
3611 | ** Support for "old-style" backquotes, obsolete for 10+ years, has |
3612 | been further reduced. Now a backquote not followed by a space is | |
3613 | always treated as a "new-style" backquote. Please remove all | |
3614 | "old-style" backquotes from your code. If your code uses backquotes | |
3615 | as documented in the Elisp manual, and compiles without warning, then | |
3616 | you have nothing to do in this regard. Code not following the | |
3617 | appropriate conventions may fail to compile. | |
50ab02c5 CY |
3618 | |
3619 | The most common cause of trouble seems to be an old-style backquote | |
3620 | followed by a newline. Another cause of trouble is vector notation | |
3621 | for key sequence notation: instead of [(control ,)] and [(control ')], | |
3622 | you should write [(control ?,)] and [(control ?')], which will work in | |
7d301ae6 | 3623 | older Emacsen too. |

520f2425 GM |
3625 | ** The macro `eval-at-startup' was removed in Emacs 23.2, but this |
3626 | was not advertised at the time. The function `custom-initialize-delay' | |
3627 | replaced all known uses. | |
3628 | ||
7d301ae6 CY |
3629 | ** `view-buffer' now treats special mode-class in the same way that |
3630 | `view-file' has since Emacs 22 (i.e. it won't enable View mode if the | |
3631 | major mode is special). | |
fd5c9dfa | 3632 | |
7d301ae6 | 3633 | ** Menu and tool bar changes |
6431f2e6 | 3634 | |
7d301ae6 | 3635 | *** During startup, Emacs no longer adds entries for `menu-bar-lines' |
0a19a6f8 JB |
3636 | and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'. |
3637 | With these alist entries omitted, `make-frame' checks the value of the | |
3638 | variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create | |
3639 | a menu-bar or tool-bar, respectively. If the alist entries are added, | |
3640 | they override the value of `menu-bar-mode'/`tool-bar-mode'. | |
6431f2e6 | 3641 | |
7d301ae6 CY |
3642 | *** The menu bar bindings's caches are not used any more. |
3643 | Use (where-is-internal <def> nil t) instead. | |
3644 | ||
fe0aa820 | 3645 | ** Regions created by mouse dragging are now normal active regions, |
dfdb4cad | 3646 | similar to those created by shift-selection (see Selection changes |
7d301ae6 CY |
3647 | above). In previous Emacs versions, these regions were delineated by |
3648 | `mouse-drag-overlay'; that variable has been removed. | |
d6d8ee7a | 3649 | |
7d301ae6 CY |
3650 | ** The fourth argument of `filter-buffer-substring' has been removed. |
3651 | If you want to remove text properties from the final result, simply | |
3652 | pass the result through substring-no-properties. | |
34c99998 | 3653 | |
4583e796 GM |
3654 | ** cl.el no longer provides `cl-19'. |
3655 | ||
7d301ae6 CY |
3656 | ** The following obsolete functions and aliases have been removed |
3657 | (the appropriate new function is given in parentheses; "not needed" | |
3658 | means you can just remove all calls to the function in question): | |
3659 | ||
3660 | *** `comint-kill-output' (`comint-delete-output') | |

3693 | ||
7d301ae6 CY |
3694 | ** The format of the finder-inf.el file has changed, since the Finder |

c2c79260 DE |
3699 | ** When generating autoloads, `update-directory-autoloads' no longer |

9097e8af | 3705 | |
041d709f | 3706 | ** Code can now use lexical scoping by default instead of dynamic scoping. |
dfdb4cad | 3707 | The `lexical-binding' variable enables lexical scoping for local |
48da7392 | 3708 | variables. It is typically set via a file-local variable in the first |
dfdb4cad CY |
3709 | line of the file, in which case it applies to all the code in that |
3710 | file. | |
3711 | ||
041d709f CY |
3712 | *** `eval' takes a new optional argument `lexical' to choose the new lexical |
3713 | binding instead of the old dynamic binding mode. | |
dfdb4cad | 3714 | |
041d709f CY |
3715 | *** Lexically scoped interpreted functions are represented with a new form |
3716 | of function value which looks like (closure ENV ARGS &rest BODY). | |
3717 | ||
3718 | *** New macro `letrec' to define recursive local functions. | |
dfdb4cad CY |
3719 | |
3720 | *** `defvar' and `defconst' now mark the variable as special (dynamic). | |
3721 | So do `defcustom' and other forms that call `defvar' as a subroutine. | |
3722 | ||
041d709f CY |
3723 | *** New function `special-variable-p' to check whether a variable is |
3724 | declared as dynamically bound. | |
3725 | ||
88ed9e87 SM |
3726 | *** The form ((lambda ...) ...) is deprecated. |
3727 | ||
041d709f CY |
3728 | ** An Emacs Lisp testing tool is now included. |
3729 | Emacs Lisp developers can use this tool to write automated tests for | |

3731 | ||
3732 | ** Changes for bidirectional display and editing | |
f1816485 | 3733 | |
041d709f | 3734 | *** New function `current-bidi-paragraph-direction'. |
7d301ae6 | 3735 | This returns the base direction of the paragraph at point. |
041d709f | 3736 | |
041d709f | 3737 | *** New function `bidi-string-mark-left-to-right'. |
dfdb4cad CY |
3738 | Given a string containing characters from right-to-left scripts, this |
3739 | function returns another string which can be safely inserted into a | |
3740 | buffer, such that any following text will be always displayed to the | |
7d301ae6 CY |
3741 | right of that string. (This works by appending an invisible Unicode |
3742 | "LEFT-TO-RIGHT MARK" character if the argument string might need it.) | |
041d709f | 3743 | |
7d301ae6 | 3744 | This is useful when the buffer has overall left-to-right paragraph |
dfdb4cad CY |
3745 | direction and you need to insert a string whose contents are not known |
3746 | in advance, without disrupting the layout of the line. | |
041d709f | 3747 | |
bee0fcef | 3748 | ** Window changes |
dfdb4cad | 3749 | |
c4682d18 MR |
3750 | *** Window tree functions are accessible in Elisp. |
3751 | Functions are provided to return the parent, siblings or child windows | |
3752 | of any window including internal windows (windows not associated with a | |
3753 | buffer) in the window tree. | |
dfdb4cad | 3754 | |
24300f5f CY |
3755 | **** New function `window-valid-p' gives non-nil for live and internal |
3756 | windows. | |
dfdb4cad | 3757 | |
24300f5f | 3758 | **** Window manipulation can deal with internal windows. |
c4682d18 MR |
3759 | Many window handling functions like `split-window', `delete-window', or |
3760 | `delete-other-windows' as well as the window resizing functions can now | |
3761 | act on any window including internal ones. | |
dfdb4cad | 3762 | |
c4682d18 MR |
3763 | *** window-total-height/-width vs window-body-height/-width. |
3764 | The function `window-height' has been renamed to `window-total-height' | |
3765 | and `window-width' has been renamed to `window-body-width'. The old | |
3766 | names are provided as aliases. Two new functions `window-total-width' | |
3767 | and `window-body-height' are provided. | |
dfdb4cad | 3768 | |
c4682d18 MR |
3769 | *** Window parameters specific to window handling functions. |
3770 | For each window you can specify a parameter to override the default | |
3771 | behavior of a number of functions like `split-window', `delete-window' | |
ed6235ea MR |
3772 | and `delete-other-windows'. The variable `ignore-window-parameters' |
3773 | allows to ignore processing such parameters. | |
dfdb4cad | 3774 | |
c4682d18 | 3775 | *** New semantics of third argument of `split-window'. |
c4682d18 MR |
3776 | The third argument of `split-window' has been renamed to SIDE and can be |
3777 | set to any of the values 'below, 'right, 'above, or 'left to make the | |
3778 | new window appear on the corresponding side of the window that shall be | |
3779 | split. Any other value of SIDE will cause `split-window' to split the | |
3780 | window into two side-by-side windows as before. | |
dfdb4cad | 3781 | |
c4682d18 | 3782 | *** Window resizing functions. |
487ffd7a | 3783 | A new standard function for resizing windows called `window-resize' has |
c4682d18 MR |
3784 | been introduced. This and all other functions for resizing windows no |
3785 | longer delete any windows when they become too small. | |
dfdb4cad | 3786 | |
b3c0dbfd MR |
3787 | *** Deleting the selected window now selects the most recently selected |
3788 | live window on that frame instead. | |
dfdb4cad | 3789 | |
c4682d18 MR |
3790 | *** `adjust-window-trailing-edge' adjustments. |
3791 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | |
3792 | is able to resize other windows if a window adjacent to the trailing | |
3793 | edge cannot be shrunk any more. This makes its behavior more similar to | |
3794 | that of Emacs 21 without compromising, however, its inability to delete | |
3795 | windows which was introduced in Emacs 22. | |
dfdb4cad | 3796 | |
c4682d18 MR |
3797 | *** Window-local buffer lists. |
3798 | Windows now have local buffer lists. This means that removing a buffer | |
3799 | from display in a window will preferably show the buffer previously | |
3800 | shown in that window with its previous window-start and window-point | |
3801 | positions. This also means that the same buffer may be automatically | |
3802 | shown twice even if it already appears in another window. | |
dfdb4cad | 3803 | |
bee0fcef CY |
3804 | *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW, |
3805 | which if non-nil requires the buffer to be displayed in the currently | |
3806 | selected window, signaling an error otherwise. If nil, another window | |
3807 | can be used, e.g. if the selected one is strongly dedicated. | |
dfdb4cad | 3808 | |
0a2132ba | 3809 | *** `split-window-vertically' and `split-window-horizontally' renamed |
2d197ffb CY |
3810 | to `split-window-below' and `split-window-right' respectively. |
3811 | The old names are kept as aliases. | |
dfdb4cad | 3812 | |
0a2132ba CY |
3813 | *** Display actions |
3814 | ||
3815 | **** The second arg to `display-buffer' and `pop-to-buffer' is now | |
3816 | named ACTION, and takes a display action of the same form as | |
3817 | `display-buffer-base-action' (see Changes, above). A non-nil, | |
3818 | non-list value is treated specially, as the old meaning. | |
3819 | ||
3820 | **** New variable `display-buffer-overriding-action'. | |
3821 | ||
3822 | **** The procedure of `display-buffer' etc. to choose a window is | |
3823 | determined by combining `display-buffer-overriding-action', | |
3824 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', | |
3825 | and `display-buffer-fallback-action'. The second and fourth of these | |
3826 | are user-customizable variables. | |
3827 | ||
3828 | See the docstring of `display-buffer' for details. | |
bee0fcef | 3829 | |
20d2304d CY |
3830 | *** New functions `window-state-get' and `window-state-put'. |
3831 | These functions allow to save and restore the state of an arbitrary | |
3832 | frame or window as an Elisp object. | |
3833 | ||
a2a25d24 | 3834 | ** Completion |
041d709f | 3835 | |
7d301ae6 CY |
3836 | *** New variable `completion-extra-properties' used to specify extra |
3837 | properties of the current completion: | |
a2a25d24 SM |
3838 | - :annotate-function, same as the old completion-annotate-function. |
3839 | - :exit-function, function to call after completion took place. | |
3840 | ||
7d301ae6 CY |
3841 | *** Functions on `completion-at-point-functions' can return any of the |
3842 | properties valid for `completion-extra-properties'. | |
a2a25d24 | 3843 | |
7d301ae6 | 3844 | *** `completion-annotate-function' is obsolete. |
a2a25d24 | 3845 | |
620c53a6 SM |
3846 | *** New `metadata' method for completion tables. The metadata thus returned |
3847 | can specify various details of the data returned by `all-completions': | |
3848 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | |
3849 | used to select a style in completion-category-overrides. | |
3850 | - `annotation-function' to add annotations in *Completions*. | |
3851 | - `display-sort-function' to specify how to sort entries in *Completions*. | |
3852 | - `cycle-sort-function' to specify how to sort entries when cycling. | |
3853 | ||
7d301ae6 CY |
3854 | *** `minibuffer-local-filename-must-match-map' is not used any more. |
3855 | Instead, the bindings in `minibuffer-local-filename-completion-map' | |
3856 | are combined with `minibuffer-local-must-match-map'. | |
de09aa52 CY |
3857 | |
3858 | *** New variable `completing-read-function' allows overriding the | |
3859 | behavior of `completing-read'. | |
3860 | ||
f042970d | 3861 | ** `glyphless-char-display' can now distinguish between graphical and |
16a43933 CY |
3862 | text terminal display, via a char-table entry that is a cons cell. |
3863 | ||
7d301ae6 | 3864 | ** `pre-command-hook'/`post-command-hook' are not reset to nil on error. |
f6d62986 SM |
3865 | Instead, the offending function is removed. |
3866 | ||
b1f6fa26 CY |
3867 | ** New hook types |
3868 | ||
3869 | *** New function `run-hook-wrapped' for running an abnormal hook by | |
3870 | passing the hook functions as arguments to a "wrapping" function. | |
e7bc51d0 | 3871 | Like `run-hook-with-args-until-success', it stops at the first |
5385447f | 3872 | non-nil return value. |
e7bc51d0 | 3873 | |
b1f6fa26 CY |
3874 | *** New macro `with-wrapper-hook' for running an abnormal hook as a |
3875 | set of "wrapping" filters, similar to around advice. | |
54521c99 GM |
3876 | (A version of this macro was actually added in Emacs 23.2 but was not |

0b19b281 | 3879 | ** Debugger changes |
dfdb4cad | 3880 | |
0b19b281 | 3881 | *** New macro `condition-case-unless-debug' (this was actually added in |
1be3ca5a | 3882 | Emacs 23.1 as condition-case-no-debug, but not advertised) |
dfdb4cad | 3883 | |
0b19b281 | 3884 | *** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised. |
dfdb4cad | 3885 | |
0b19b281 | 3886 | *** Variable `stack-trace-on-error' removed. |
dfdb4cad | 3887 | |
0b19b281 CY |
3888 | *** The debugger can now "continue" from an error, which means it will |
3889 | jump to the error handler as if the debugger had not been invoked | |
3890 | instead of jumping all the way to the top-level. | |
dfdb4cad | 3891 | |
0b19b281 CY |
3892 | *** Set `debug-on-event' to enter the debugger on events like SIGUSR1. |

3899 | to redirect STDOUT to a file. | |
7deebf1b | 3900 | |
7d301ae6 CY |
3901 | ** The function `format-time-string' now supports the %N directive, |
3902 | for higher-resolution time stamps. | |
da97a9e6 | 3903 | |
0b19b281 | 3904 | ** New input reading functions |
dfdb4cad | 3905 | |
0b19b281 CY |
3906 | *** New function `read-char-choice' reads a restricted set of |
3907 | characters, discarding any inputs not inside the set. | |
dfdb4cad | 3908 | |
0b19b281 CY |
3909 | *** The command `read-color' now requires a match for a color name |
3910 | or RGB triplet, instead of signaling an error if the user provides | |
3911 | invalid input. | |
dfdb4cad | 3912 | |
0b19b281 | 3913 | **** `facemenu-read-color' is now an alias for `read-color'. |
3ef01959 | 3914 | |
2e288d54 JB |
3915 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
3916 | The variable is now used to load all kind of supported dynamic libraries, | |
3917 | not just image libraries. The previous name is still available as an | |
3918 | obsolete alias. | |
3919 | ||
0b19b281 | 3920 | ** Syntax parsing changes |
dfdb4cad | 3921 | |
0b19b281 | 3922 | *** New variable `syntax-propertize-function'. |
04e2ce72 | 3923 | This replaces `font-lock-syntactic-keywords' which is now obsolete. |
cf38dd42 SM |
3924 | This allows syntax-table properties to be set independently from font-lock: |
3925 | just call syntax-propertize to make sure the text is propertized. | |
3926 | Together with this new variable come a new hook | |
3927 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
3928 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
3929 | as-is; and syntax-propertize-rules which provides a new way to specify | |
3930 | syntactic rules. | |
dfdb4cad | 3931 | |
0b19b281 | 3932 | *** Syntax tables support a new "comment style c" additionally to style b. |
a2e5caf7 | 3933 | |
7d301ae6 | 3934 | ** New hook `post-self-insert-hook', run after `self-insert-command'. |
041d709f | 3935 | |
4e2db1fe | 3936 | ** frame-local variables cannot be let-bound any more. |
041d709f | 3937 | |
15de15c6 | 3938 | ** Major and minor mode changes |
dfdb4cad | 3939 | |
0b19b281 CY |
3940 | *** `set-auto-mode' now respects mode: local variables at the end of files, |
3941 | as well as those in the -*- line. | |
dfdb4cad | 3942 | |
15de15c6 CY |
3943 | *** `prog-mode' is a new major mode from which programming modes |
3944 | should be derived. | |
dfdb4cad | 3945 | |
15de15c6 CY |
3946 | **** `prog-mode-hook' can be used to enable features for programming |
3947 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable | |
3948 | on-the-fly spell checking for comments and strings. | |
dfdb4cad | 3949 | |
15de15c6 CY |
3950 | *** New hook `change-major-mode-after-body-hook', run by |
3951 | `run-mode-hooks' just before any other mode hooks. | |
dfdb4cad | 3952 | |
7a9a2fc6 GM |
3953 | *** Enabled globalized minor modes can be disabled in specific major modes. |
3954 | If the global mode is global-FOO-mode, then run (FOO-mode -1) in the | |
3955 | major mode's hook, where FOO-mode toggles the mode on a per-buffer basis. | |
dfdb4cad | 3956 | |
feb8a83a | 3957 | *** `define-minor-mode' accepts new keywords :variable, :after-hook. |
f44379e7 | 3958 | |
7d301ae6 CY |
3959 | ** File-handling changes |
3960 | ||
7d301ae6 | 3961 | *** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
3962 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
3963 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
3964 | argument is supplied (see Trash changes, above). | |
53967e09 | 3965 | |
7d301ae6 | 3966 | *** New file predicates: `file-equal-p', `file-in-directory-p'. |
ec70a47d | 3967 | |
4039c786 CY |
3968 | ** Tool-bars can display separators. |
3969 | Tool-bar separators are handled like menu separators in menu-bar maps, | |
94975270 | 3970 | i.e. via menu entries of the form `(menu-item "--")'. |
9317e499 | 3971 | |
00fe2df1 JL |
3972 | ** Image API |
3973 | ||
18af70d0 CY |
3974 | *** Animated images support (currently animated gifs only). |
3975 | ||
3976 | **** `image-animated-p' returns non-nil if an image can be animated. | |
3977 | ||
3978 | **** `image-animate' animates a supplied image spec. | |
3979 | ||
3980 | **** `image-animate-timer' returns the timer object for an image that | |
3981 | is being animated. | |
00fe2df1 | 3982 | |
7cb76fe0 GM |
3983 | *** `image-extension-data' has been renamed to `image-metadata'. |
3984 | The old name is an obsolete alias to the new one. | |
1546c559 | 3985 | |
b4ac6e8c GM |
3986 | *** Image mode can view any image type that ImageMagick supports. |
3987 | This requires Emacs to be built with ImageMagick support. | |
7d301ae6 CY |
3988 | |
3989 | **** New function `imagemagick-types', defined if ImageMagick support | |
3990 | is enabled, returns a list of image file extensions that your | |
3991 | ImageMagick installation supports. | |
3992 | ||
3993 | **** New function `imagemagick-register-types' enables ImageMagick | |
3994 | image types in Image mode and in `create-image' and other helper | |
3995 | functions. | |
3996 | ||
3997 | **** New option `imagemagick-types-inhibit' excludes certain | |
3998 | ImageMagick image types from `imagemagick-register-types'. | |
3999 | ||
7d301ae6 CY |
4000 | **** With ImageMagick support, there are extra Image mode commands to |
4001 | resize and rotate images: `image-transform-fit-to-height', | |
4002 | `image-transform-fit-to-width', `image-transform-set-rotation', and | |
4003 | `image-transform-set-scale'. | |
041d709f | 4004 | |
7d301ae6 CY |
4005 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
4006 | passes it to the mail user agent function. This argument specifies an | |
4007 | action for returning to the caller after finishing with the mail. For | |
4008 | example, this is used by Rmail to optionally delete a mail window. | |
b4ac6e8c | 4009 | |
71c17aec | 4010 | ** XML and HTML parsing |
483ab230 CY |
4011 | If Emacs is compiled with libxml2 support, there are two new |
4012 | functions: `libxml-parse-html-region' (which parses "real world" HTML) | |
4013 | and `libxml-parse-xml-region' (which parses XML). Both return an | |
4014 | Emacs Lisp parse tree. | |
4b9832a6 | 4015 | |
7d301ae6 | 4016 | ** Networking and encryption changes |
e2574f2c | 4017 | |
7d301ae6 CY |
4018 | *** `open-network-stream' can now be used to open an encrypted stream. |
4019 | It now accepts an optional `:type' parameter for initiating a TLS | |
4020 | connection, directly or via STARTTLS. To do STARTTLS, additional | |
4021 | parameters (`:end-of-command', `:success', `:capabilities-command') | |
4022 | must also be supplied. | |
4023 | ||
4024 | *** New library gnutls.el. | |
dfdb4cad CY |
4025 | The new function `gnutls-available-p' returns non-nil if Emacs is |
4026 | built with GnuTLS support. The main entry points are | |
4027 | `open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use | |
4028 | these functions through `open-network-stream', because that can | |
7d301ae6 CY |
4029 | upgrade connections through STARTTLS opportunistically or use plain |
4030 | SSL, depending on your needs. For debugging, set `gnutls-log-level' | |
4031 | greater than 0. | |
4032 | ||
7d301ae6 CY |
4033 | *** New primitive `secure-hash' that supports many secure hash algorithms: |
4034 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library | |
4035 | sha1.el has been removed. The `sha1' feature is provided by default. | |
71c17aec | 4036 | |
a6020335 MH |
4037 | ** Isearch |
4038 | ||
4039 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | |
4040 | ||
9326ba26 CY |
4041 | ** Progress reporters can now "spin". |
4042 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
4043 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
4044 | time you call `progress-reporter-update' on that progress reporter, | |
4045 | with a nil or omitted VALUE argument, the reporter message is | |
4046 | displayed with a "spinning bar". | |
4047 | ||
3e214b50 JB |
4048 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is |
4049 | being reverted, even if the buffer has a local `revert-buffer-function'. | |
4050 | ||
001bf877 GM |
4051 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. |
4052 | If delayed-warnings-list is non-nil, the command loop calls | |
7d301ae6 CY |
4053 | `delayed-warnings-hook' after `post-command-hook'. At present, this |
4054 | is only used by Emacs on some platforms to display warnings during | |
4055 | startup, which might otherwise not be noticed. This uses the | |
4056 | functions `display-delayed-warnings' and `collapse-delayed-warnings'. | |
001bf877 | 4057 | |
6420d28b CY |
4058 | ** rx.el has a new `group-n' construct for explicitly numbered groups. |
4059 | ||
dac86404 GM |
4060 | ** New function `make-composed-keymap' that constructs a new keymap |
4061 | from multiple input maps. You can use this to make a keymap that | |
4062 | inherits from multiple maps, eg: | |
4063 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) | |
43dc9f5b | 4064 | |
c8f6ec5c GM |
4065 | ** New function `string-prefix-p'. |
4066 | (This was actually added in Emacs 23.2 but was not advertised at the time.) | |
4067 | ||
27f7ef2f | 4068 | ** New reader macro ## that stands for the empty symbol. |
43dc9f5b AS |
4069 | This means that the empty symbol can now be read back. Also, #: by itself |
4070 | (when not immediately followed by a possible symbol character) stands for | |
4071 | an empty uninterned symbol. | |
041d709f | 4072 | |
fead402d CY |
4073 | ** New math functions `isnan', `copysign', `frexp', `ldexp'. |
4074 | ||
7d301ae6 | 4075 | ** The following functions and variables are obsolete: |
041d709f | 4076 | |
05f77e38 GM |
4077 | *** `tooltip-use-echo-area' is obsolete. |
4078 | Rather than setting this to t, disable Tooltip mode instead. | |
4079 | ||
041d709f CY |
4080 | *** buffer-substring-filters is obsolete. |
4081 | Use `filter-buffer-substring-functions' instead. | |
4082 | ||
4083 | *** `byte-compile-disable-print-circle' is obsolete. | |
4084 | ||
4085 | *** `deferred-action-list' and `deferred-action-function' are obsolete. | |
f160676e GM |
4086 | Use `post-command-hook' instead. |
4087 | ||
67e729a5 CY |
4088 | *** `font-lock-maximum-size' is obsolete. |
4089 | ||
eb199145 | 4090 | \f |
93e0bed6 | 4091 | * Changes in Emacs 24.1 on Non-Free Operating Systems |
d53a60a6 | 4092 | |
7a22e700 | 4093 | ** On MS Windows, Emacs warns when using the obsolete init file _emacs, |
a2f0118c GM |
4094 | and also when HOME is set to C:\ by default. |
4095 | ||
7a22e700 | 4096 | ** New configure.bat options |
04779484 | 4097 | |
7a22e700 | 4098 | *** --enable-checking builds Emacs with extra runtime checks. |
e3aef5c6 | 4099 | |
7a22e700 | 4100 | *** --distfiles specifies files to be included in binary distribution. |
e2574f2c | 4101 | |
7a22e700 OK |
4102 | *** --without-gnutls disables automatic GnuTLS detection. |
4103 | ||
a0d363f4 | 4104 | *** --lib for general library linkage, works with the USER_LIBS build variable. |
e2574f2c | 4105 | |
0a19a6f8 | 4106 | ** New make target `dist' to create binary distribution for MS Windows. |
e3aef5c6 | 4107 | |
1f5e1a16 GM |
4108 | ** The Lisp function `w32-default-color-map' is now obsolete. |
4109 | (It is only used internally in the Emacs C code.) | |
5430d399 | 4110 | |
1f5e1a16 GM |
4111 | ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but |
4112 | reappear on mouse-over. (Requires OS X 10.6 or later.) | |
04e2ce72 | 4113 | |
ad7c802c CY |
4114 | ** On Mac OS X, dragging a file into Emacs visits the file, like on |
4115 | other platforms, rather than inserting its contents into the buffer. | |
