95a32efb | 25 | * Installation Changes in Emacs 24.4 |
7c3d167f | 26 | |
70c8f5ca | 27 | ** Emacs can now be compiled with ACL support. |
7c3d167f RF |
28 | This happens by default if a suitable support library is found at |
29 | build time, like libacl on GNU/Linux. To prevent this, use the | |
ffdc270a | 30 | configure option `--disable-acl'. |
7c3d167f | 31 | |
70c8f5ca | 32 | ** Emacs can now be compiled with file notification support. |
671d4bfc GM |
33 | This happens by default if a suitable system library is found at |
34 | build time. To prevent this, use the configure option | |
35 | `--with-file-notification-no'. See below for file-notify features. | |
36 | FIXME? This feature is not available for the Nextstep port. (?) | |
2f23b3ab | 37 | |
d65a92bb | 38 | --- |
70c8f5ca CY |
39 | ** The configure option `--without-compress-info' has been generalized, |
40 | and renamed to `--without-compress-install'. It now prevents compression | |
335142f9 GM |
41 | of _any_ files during installation. |
42 | ||
d65a92bb | 43 | --- |
70c8f5ca | 44 | ** The configure option `--with-crt-dir' has been removed. |
f1e496a5 EZ |
45 | It is no longer needed, as the crt*.o files are no longer linked |
46 | specially. | |
47 | ||
d65a92bb | 48 | --- |
ae7bfbf5 JB |
49 | ** Directories passed to configure option `--enable-locallisppath' are |
50 | no longer created during installation. | |
51 | ||
70c8f5ca CY |
52 | ** Emacs can be compiled with zlib support. |
53 | If this library is present (which it normally is on most systems), the | |
54 | function `zlib-decompress-region' becomes available, which can | |
55 | decompress gzip- and zlib-format compressed data. | |
313546eb | 56 | |
9524a13d | 57 | --- |
8251c3f8 GM |
58 | ** Emacs for NS (Mac OS X, GNUstep) can be built with ImageMagick support. |
59 | This requires pkg-config to be available at configure time. | |
9524a13d | 60 | |

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

95a32efb | 90 | * Changes in Emacs 24.4 |
c6c08d3f | 91 | |
d8a2993d TZ |
92 | +++ |
93 | ** New option `gnutls-verify-error', if non-nil, means that Emacs | |
94 | should reject SSL/TLS certificates that GnuTLS determines as invalid. | |
95 | (This option defaults to nil at present, but this is expected to change | |
96 | in a future release.) | |
97 | ||
0a12fca0 EZ |
98 | +++ |
99 | ** Emacs now supports menus on text-mode terminals. | |
100 | If the terminal supports a mouse, clicking on the menu bar, or on | |
101 | sensitive portions of the mode line or header line, will drop down the | |
102 | menu defined at that position. Likewise, clicking C-mouse-2 or | |
103 | C-mouse-2 or C-mouse-3 on the text area will pop up the menus defined | |
104 | for those locations. | |
105 | ||
106 | If the text terminal does not support a mouse, you can activate the | |
107 | first menu-bar menu by typing F10, which invokes `menu-bar-open'. | |
108 | ||
109 | If you want the previous behavior, whereby F10 invoked `tmm-menubar', | |
110 | customize the option `tty-menu-open-use-tmm' to a non-nil value. | |
111 | (Typing M-` will always invoke `tmm-menubar', even if | |
112 | `tty-menu-open-use-tmm' is nil.) | |
113 | ||
a34a0ac8 | 114 | +++ |
70c8f5ca CY |
115 | ** The *Messages* buffer is created in `messages-buffer-mode', |
116 | a new major mode, with read-only status. Any code that might create | |
117 | the *Messages* buffer should call the function `messages-buffer' to do | |
118 | so and set up the mode. | |
61a5bb85 | 119 | |
70c8f5ca | 120 | ** Emacs now supports ACLs (access control lists). |
7c3d167f RF |
121 | +++ |
122 | *** Emacs preserves the ACL entries of files when backing up. | |
123 | +++ | |
124 | *** New functions `file-acl' and `set-file-acl' get and set the ACL | |
66447e07 EZ |
125 | entries of a file. On GNU/Linux, the POSIX ACL interface is used via |
126 | libacl. On MS-Windows, the NT Security APIs are used to emulate the | |
127 | POSIX ACL interfaces. | |
7c3d167f | 128 | |
4e3f9230 YM |
129 | ** Multi-monitor support has been added. |
130 | ||
131 | *** New functions `display-monitor-attributes-list' and | |
132 | `frame-monitor-attributes' can be used to obtain information about | |
133 | each physical monitor on multi-monitor setups. | |
134 | ||
cf13177e YM |
135 | *** The functions `display-pixel-width' and `display-pixel-height' now |
136 | behave consistently among the platforms: they return the pixel width | |
137 | or height for all physical monitors associated with the given display | |
950fb38d | 138 | as if they were on X11. To get information for each physical |
cf13177e YM |
139 | monitor, use the new functions above. Similar notes also apply to |
140 | `x-display-pixel-width', `x-display-pixel-height', `display-mm-width', | |
141 | `display-mm-height', `x-display-mm-width', and `x-display-mm-height'. | |
142 | ||
70c8f5ca CY |
143 | +++ |
144 | ** The cursor stops blinking after 10 blinks (by default) on X and NS. | |
145 | You can change the default by customizing `blink-cursor-blinks'. | |
61e56e2c | 146 | |
70c8f5ca CY |
147 | +++ |
148 | ** In keymaps where SPC scrolls forward, S-SPC now scrolls backward. | |
149 | This affects View mode, etc. | |
150 | ||
151 | ** Help changes | |
f88ac3bb | 152 | |
98104aea | 153 | +++ |
70c8f5ca CY |
154 | *** The command `apropos-variable' is renamed to `apropos-user-option'. |
155 | `apropos-user-option' shows all user options while `apropos-variable' | |
156 | shows all variables. When called with a universal prefix argument, | |
157 | the two commands swap their behaviors. When `apropos-do-all' is | |
158 | non-nil, they output the same results. | |
18c26d81 | 159 | |
70c8f5ca CY |
160 | +++ |
161 | *** The key `?' now describes prefix bindings, like `C-h'. | |
6585d561 | 162 | |
8251c3f8 | 163 | *** The command `describe-function' has been extended for EIEIO. |
3ca34b22 | 164 | Running it on constructors will show a full description of the |
d6a62260 | 165 | generated class. For generic functions, it will show all |
3ca34b22 DE |
166 | implementations together with links to the source. The old commands |
167 | `describe-class', `describe-constructor' and `describe-generic' were | |
168 | removed. | |
169 | ||
44e76f9d GM |
170 | --- |
171 | *** The function `quail-help' is no longer an interactive command. | |
8251c3f8 | 172 | Use `C-h C-\' (`describe-input-method') instead. |
6950f152 | 173 | |
b29daf07 GM |
174 | ** ImageMagick |
175 | ||
4e7d26fc | 176 | +++ |
8251c3f8 | 177 | *** ImageMagick images now support the :max-width and :max-height keywords. |
b29daf07 | 178 | |
7b997b14 GM |
179 | +++ |
180 | *** When using `create-image' with image data, you can pass a :format | |
181 | attribute (via the property-list argument) in order to help | |
182 | ImageMagick detect the image type. The value should be a MIME | |
183 | content-type that is found in the new variable `image-format-suffixes'. | |
b29daf07 | 184 | |
70c8f5ca | 185 | ** Frame and window changes |
da9ea6d9 | 186 | |
70c8f5ca CY |
187 | +++ |
188 | *** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized', | |
189 | bound to <f11> and M-<f10>, respectively. | |
0a749fa0 | 190 | |
70c8f5ca CY |
191 | *** New command `frameset-to-register' is now bound to `C-x r f', replacing |
192 | `frame-configuration-to-register'. It offers similar functionality, | |
193 | plus enhancements like the ability to restore deleted frames. The | |
194 | command `frame-configuration-to-register' still exists, but is unbound. | |
0a749fa0 | 195 | |
dc20a9d2 | 196 | +++ |
70c8f5ca CY |
197 | *** New hooks `focus-in-hook', `focus-out-hook'. |
198 | These are normal hooks run when an Emacs frame gains or loses input focus. | |
199 | ||
200 | --- | |
201 | *** `split-window' is now a non-interactive function, not a command. | |
202 | As a command, it was a special case of `C-x 2' (`split-window-below'), | |
203 | and as such superfluous. After being reimplemented in Lisp, its | |
204 | interactive form was mistakenly retained. | |
4f0552c2 | 205 | |
daef8ab1 | 206 | +++ |
70c8f5ca CY |
207 | *** New option `scroll-bar-adjust-thumb-portion'. |
208 | Available only on X, this option allows to control over-scrolling | |
209 | using the scroll bar (i.e. dragging the thumb down even when the end | |
210 | of the buffer is visible). | |
211 | ||
212 | ** Lisp evaluation changes | |
75a1e034 | 213 | +++ |
70c8f5ca CY |
214 | *** `eval-defun' on an already defined defcustom calls the :set function, |
215 | if there is one. | |
216 | ||
c51e81ef | 217 | +++ |
d856c4a9 | 218 | *** The commands `eval-expression' (`M-:'), `eval-last-sexp' (`C-x C-e'), |
c51e81ef GM |
219 | and `eval-print-last-sexp' (`C-j' in Lisp Interaction mode) can take a |
220 | zero prefix argument. This disables truncation of lists in the output, | |
221 | equivalent to setting `(eval-expression-)print-length' and | |
4d000e69 | 222 | `(eval-expression-)print-level' to nil. Additionally, it causes integers |
c51e81ef | 223 | to be printed in other formats (octal, hexadecimal, and character). |
70c8f5ca CY |
224 | |
225 | --- | |
226 | ** `write-region-inhibit-fsync' now defaults to t in batch mode. | |
da048127 | 227 | |
2cd12d28 | 228 | +++ |
70c8f5ca CY |
229 | ** `cache-long-line-scans' has been renamed to `cache-long-scans' |
230 | because it affects caching of paragraph scanning results as well. | |
8251c3f8 | 231 | Also, it is now enabled by default. |
4e36a6a6 | 232 | |
70c8f5ca CY |
233 | --- |
234 | ** The option `set-mark-default-inactive' has been deleted. | |
235 | This unfinished feature was introduced by accident in Emacs 23.1; | |
236 | simply disabling Transient Mark mode does the same thing. | |
237 | ||
8251c3f8 | 238 | ** The default value of `comment-use-global-state' is now t, |
70c8f5ca CY |
239 | and this variable has been marked obsolete. |
240 | ||
8251c3f8 | 241 | --- |
e2a095b1 GM |
242 | ** `emacs-bzr-version' has been renamed to `emacs-repository-version', |
243 | and works for git too, if you fetch the repository notes. | |
8251c3f8 | 244 | |
642d7ae8 CY |
245 | ** New user options: |
246 | ||
247 | *** `read-regexp-defaults-function' defines a function to read regexps, | |
8251c3f8 GM |
248 | used by commands like `rgrep', `lgrep' `occur', `highlight-regexp', etc. |
249 | You can customize this to specify a function that provides a default | |
250 | value from the regexp last history element, or from the symbol found | |
251 | at point. | |
642d7ae8 | 252 | |
ec918aab | 253 | +++ |
950fb38d | 254 | *** `load-prefer-newer' affects how the `load' function chooses the |
642d7ae8 CY |
255 | file to load. If this is non-nil, then when both .el and .elc |
256 | versions of a file exist, and the caller did not explicitly specify | |
257 | which one to load, then the newer file is loaded. The default, nil, | |
258 | means to always load the .elc file. | |

261 | * Editing Changes in Emacs 24.4 | |
262 | ||
263 | ** Indentation changes | |
264 | ||
265 | +++ | |
266 | *** The behavior of `C-x TAB' (`indent-rigidly') has changed. | |
267 | When invoked without a prefix argument, it now activates a transient | |
268 | mode in which typing <left>, <right>, <S-left>, and <S-right> adjusts | |
269 | the text indentation in the region. Typing any other key resumes | |
270 | normal editing behavior. | |
3472b6c6 | 271 | |
70c8f5ca | 272 | *** `electric-indent-mode' is enabled by default. |
b7d5bd82 | 273 | |
70c8f5ca | 274 | *** `tab-stop-list' is now implicitly extended to infinity by repeating |
8251c3f8 | 275 | the last step. Its default value is changed to nil, which means a tab |
3ccc2d28 | 276 | stop every `tab-width' columns. |
b7d5bd82 | 277 | |
70c8f5ca | 278 | ** Filling changes |
0aa3616e | 279 | |
70c8f5ca CY |
280 | *** New command `cycle-spacing' cycles between spacing conventions: |
281 | having just one space, no spaces, or reverting to the original | |
282 | spacing. Like `just-one-space', it can handle or ignore newlines and | |
283 | leave different number of spaces. | |
284 | ||
285 | *** `fill-single-char-nobreak-p' prevents fill from breaking a line after | |
286 | a 1-letter word, which is an error according to Polish and | |
287 | Czech typography rules. To globally enable this feature, evaluate: | |
288 | ||
289 | (add-hook 'fill-nobreak-predicate 'fill-single-char-nobreak-p) | |
37f38bca | 290 | |
30aafaf5 | 291 | +++ |
8251c3f8 | 292 | ** Uniquify is enabled by default, with `post-forward-angle-brackets' style. |
70c8f5ca CY |
293 | |
294 | ** New command `C-x SPC' (`rectangle-mark-mode') makes a rectangular region. | |
295 | Most commands are still unaware of it, but kill/yank do work on the rectangle. | |
958614cf | 296 | |
4c672a0f EZ |
297 | +++ |
298 | ** New option `visual-order-cursor-movement'. | |
299 | If this is non-nil, cursor motion with arrow keys will follow the | |
300 | visual order of characters on the screen: <left> always moves to the | |
301 | left, <right> always moves to the right, disregarding the surrounding | |
302 | bidirectional context. | |

379 | ** Calc |
380 | ||
381 | *** Calc by default now uses the Gregorian calendar for all dates, and | |
382 | uses January 1, 1 AD as its day number 1. Previously Calc used the | |
383 | Julian calendar for dates before September 14, 1752, and it used | |
384 | December 31, 1 BC as its day number 1; the new scheme is more | |
385 | consistent with Calendar's calendrical system and day numbering. | |
386 | ||
387 | *** The new variable `calc-gregorian-switch' lets you configure the | |
388 | date when Calc switches from the Julian to the Gregorian calendar. | |
389 | Nil, the default value, means to always use the Gregorian calendar. | |
390 | The value (YEAR MONTH DAY) means to start using the Gregorian calendar | |
391 | on the given date. | |

8251c3f8 | 477 | *** New option `electric-pair-delete-adjacent-pairs', enabled by default. |
3b8d5131 JT |
478 | In `electric-pair-mode', the commands `backward-delete-char' and |
479 | `backward-delete-char-untabify' are now bound to electric variants | |
480 | that delete the closer when invoked between adjacent pairs. | |
481 | ||
8251c3f8 | 482 | *** New option `electric-pair-open-newline-between-pairs', enabled by default. |
3b8d5131 JT |
483 | In `electric-pair-mode', inserting a newline between adjacent pairs |
484 | opens an extra newline after point, which is indented if | |
485 | `electric-indent-mode' is also set. | |
486 | ||
8251c3f8 GM |
487 | *** New option `electric-pair-skip-whitespace', enabled by default. |
488 | This controls if skipping over closing delimiters should jump over any | |
489 | whitespace slack. Setting it to `chomp' makes it delete this | |
490 | whitespace. See also the variable `electric-pair-skip-whitespace-chars'. | |
3b8d5131 JT |

ed02dcfa RS |
497 | ** EPA |
498 | ||
499 | *** New option `epa-mail-aliases'. | |
ed02dcfa RS |
500 | You can set this to a list of alias expansions for keys to use |
501 | in `epa-mail-encrypt'. | |
502 | ||
503 | If one element of the variable's value is ("foo@bar.com" "foo@hello.org"), | |
504 | that means: when one of the recipients of the message being encrypted | |
505 | is `foo@bar.com', encrypt the message for `foo@hello.org' instead. | |
506 | ||
507 | If one element of the variable's value is ("foo@bar.com"), | |
508 | that means: when one of the recipients of the message being encrypted | |
509 | is `foo@bar.com', ignore that name as regards encryption. | |
510 | This is useful to avoid a query when you have no key for that name. | |

523 | ||
524 | +++ | |
8251c3f8 | 525 | *** `eshell' now supports visual subcommands and options. |
70c8f5ca CY |
526 | Eshell has been able to handle "visual" commands (interactive, |
527 | non-line oriented commands such as top that require display | |
528 | capabilities not provided by eshell) by running them in an Emacs | |
529 | terminal emulator. See `eshell-visual-commands'. | |
530 | ||
531 | This feature has been extended to subcommands and options that make a | |
532 | usually line-oriented command a visual command. Typical examples are | |
8251c3f8 | 533 | "git log" and "git <command> --help", which display their output in a |
70c8f5ca CY |
534 | pager by default. See `eshell-visual-subcommands' and |
535 | `eshell-visual-options'. | |

2d3c36db GM |
777 | The Todo mode user manual describes all commands and most user |
778 | options. To support some of these features, a new file format is | |
779 | used, which is incompatible with the old format; however, you can | |
780 | convert old todo and done item files to the new format on initializing | |
781 | the first new todo file, or at any later time with the provided | |
782 | conversion command. The previous version of todo-mode.el has been | |
303ea1dd GM |
783 | renamed to otodo-mode.el and is now obsolete. New features include: |
784 | ||
785 | *** Support for multiple todo files and archive files of done items. | |
786 | ||
787 | *** Renaming, reordering, moving, merging, and deleting categories. | |

789 | *** Sortable tabular summaries of categories and the item types they contain. | |
790 | ||
791 | *** Cross-category lists of items filtered by specific criteria. | |
792 | ||
793 | *** More fine-grained interaction with the Emacs diary, by being able to | |
794 | decide for each todo item whether it appears in the Fancy Diary display. | |
795 | ||
796 | *** Highly flexible new item insertion and item editing. | |
797 | ||
798 | *** Moving items between categories, storing done items in their category | |
799 | or in archive files, undoing or unarchiving done items. | |
800 | ||
801 | *** Reprioritizing items by inputting a numerical priority. | |

810 | expression whose value at the time the function is entered/exited will | |
811 | be printed along with the function name and arguments. For example, | |

1258 | ** Changes in encoding and decoding of text |
1259 | ||
1260 | --- | |
1261 | *** New coding-system `prefer-utf-8'. | |
1262 | This is like `undecided' but prefers UTF-8 on decoding if the text to | |
1263 | be decoded does not contain any invalid UTF-8 sequences. On encoding, | |
1264 | any non-ASCII characters are automatically encoded as UTF-8. | |
1265 | ||
1266 | --- | |
1267 | *** New attributes of coding-systems whose type is `undecided'. | |
1268 | Two new attributes, `:inhibit-null-byte-detection' and | |
1269 | `:inhibit-iso-escape-detection', determine how to detect encoding of | |
1270 | text that includes null bytes and ISO-2022 escape sequences, | |
1271 | respectively. Each of these attributes can be either nil, zero, or | |
1272 | t. If it is t, decoding text ignores null bytes and, respectively, | |
1273 | ISO-2022 sequences. If it is nil, null bytes cause text to be decoded | |
1274 | with no-conversion and ISO-2022 sequences cause Emacs to assume the | |
1275 | text is encoded in one of the ISO-2022 encodings, such as | |
1276 | iso-2022-7bit. If the value is zero, Emacs consults the variables | |
1277 | inhibit-null-byte-detection and inhibit-iso-escape-detection, which | |
1278 | see. | |
1279 | The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer | |
1280 | UTF-8 encoding and decoding, whenever possible. | |
1281 | ||
1282 | These attributes are only meaningful for coding-systems of type | |
1283 | `undecided'. (The type of a coding-system is determined by its | |
1284 | `:coding-type' attribute and can be accessed by calling the | |
1285 | `coding-system-type' function.) | |

1301 | Emacs makes no attempt to lock DIR/FILE. (Previously, it fell back to | |
1302 | numbered lock files DIR/.#FILE.0...). | |

671d4bfc GM |

1322 | Using the Posix configure script and Makefile's also means a change in | |
1323 | the directory structure of the Emacs installation on Windows. It is | |

1325 | programs, such as cmdproxy.exe and hexl.exe, are in | |
1326 | libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs | |

1328 | version-specific Lisp files are in share/emacs/VERSION/lisp and in | |
1329 | share/emacs/VERSION/site-lisp, Info docs are in share/info, and data | |
1330 | files are in share/emacs/VERSION/etc. (Emacs knows about all these | |

1487 | *** emacsclient now obeys string values for `initial-buffer-choice', |

1492 | |
1493 | ** Emacs now generates backtraces on fatal errors. | |
1494 | On encountering a fatal error, Emacs now outputs a textual description | |
1495 | of the fatal signal, and a short backtrace on platforms like glibc | |
5248293f | 1496 | that support backtraces. |
2e2d2a13 | 1497 | |
6bc66c10 GM |
1498 | ** `C-x C-q' is now bound to the new minor mode `read-only-mode'. |
1499 | This minor mode replaces `toggle-read-only', which is now obsolete. | |
1500 | ||
1501 | ** Most `y-or-n' prompts now allow you to scroll the selected window. | |
1502 | Typing `C-v' or `M-v' at a y-or-n prompt scrolls forward or backward | |
1503 | respectively, without exiting from the prompt. | |
1504 | ||
1505 | ** In the Package Menu, newly-available packages are listed as "new", | |
1506 | and sorted above the other "available" packages by default. | |

9475054f | 1508 | ** If your Emacs was built from a repository checkout, the new variable |
0bfbd67c | 1509 | `emacs-bzr-version' contains information about the bzr revision used. |
de6ff46d | 1510 | |
6bc66c10 | 1511 | ** New option `create-lockfiles' specifies usage of lockfiles. |
f938eda9 CY |
1512 | It defaults to t. Changing it to nil inhibits the creation of lock |
1513 | files (use this with caution). | |

1524 | ** In the buffer made by `M-x report-emacs-bug', the `C-c m' binding |
1525 | has been changed to `C-c M-i' (`report-emacs-bug-insert-to-mailer'). | |
1526 | The previous binding, introduced in Emacs 24.1, was a mistake, because | |
1527 | `C-c LETTER' bindings are reserved for user customizations. | |
1528 | ||
6bc66c10 | 1529 | ** Internationalization |
2f940384 | 1530 | |

6bc66c10 | 1545 | ** Search and Replace |
d39d3c8e | 1546 | |
f938eda9 CY |
1547 | *** Non-regexp Isearch now performs "lax" space matching. |
1548 | Each sequence of spaces in the supplied search string may match any | |
1549 | sequence of one or more whitespace characters, as specified by the | |
1550 | variable `search-whitespace-regexp'. (This variable is also used by a | |
823b2fb6 | 1551 | similar existing feature for regexp Isearch.) |
2f940384 | 1552 | |
f938eda9 CY |
1553 | *** New Isearch command `M-s SPC' toggles lax space matching. |
1554 | This applies to both ordinary and regexp Isearch. | |
2f940384 | 1555 | |
f938eda9 CY |
1556 | *** New option `replace-lax-whitespace'. |
1557 | If non-nil, `query-replace' uses flexible whitespace matching too. | |
1558 | The default is nil. | |
2f940384 | 1559 | |
b9cb2387 JL |
1560 | *** Global `M-s _' starts a symbol (identifier) incremental search, |
1561 | and `M-s _' in Isearch toggles symbol search mode. | |
1562 | `M-s c' in Isearch toggles search case-sensitivity. | |

6bc66c10 | 1564 | ** Navigation commands |
48de8b12 | 1565 | |
6bc66c10 GM |
1566 | *** New binding `M-g c' for `goto-char'. |
1567 | ||
1568 | *** New binding `M-g TAB' for `move-to-column'. | |
1569 | ||
1570 | *** `M-g TAB' (`move-to-column') prompts for a column number if called | |
1571 | interactively with no prefix arg. Previously, it moved to column 1. | |
1572 | ||
1573 | ** New option `yank-handled-properties' allows processing of text | |
1574 | properties on yanked text, in ways that are more general than just | |
1575 | removing them (as is done by `yank-excluded-properties'). | |
48de8b12 | 1576 | |
48de8b12 CY |
1577 | ** New option `delete-trailing-lines' specifies whether |
1578 | M-x delete-trailing-whitespace should delete trailing lines at the end | |
1579 | of the buffer. It defaults to t. | |
1580 | ||
f938eda9 | 1581 | ** `C-u M-=' now counts lines/words/characters in the entire buffer. |
826b3235 | 1582 | |
48de8b12 CY |
1583 | ** `C-x 8 RET' is now bound to `insert-char', which is now a command. |
1584 | `ucs-insert' is now an obsolete alias for `insert-char'. | |
b2459884 | 1585 | |
48de8b12 CY |
1586 | ** The `z' key no longer has a binding in most special modes. |
1587 | It used to be bound to `kill-this-buffer', but `z' is too easy to | |
1588 | accidentally type. | |
f938eda9 | 1589 | |
6bc66c10 GM |
1590 | ** New command `C-x r M-w' (`copy-rectangle-as-kill'). |

6bc66c10 | 1604 | ** Common Lisp emulation (CL) |
f938eda9 | 1605 | |
89660017 | 1606 | *** CL's main entry is now (require 'cl-lib). |
823b2fb6 GM |
1607 | `cl-lib' is like the old `cl' except that it uses the namespace cleanly; |
1608 | i.e., all its definitions have the "cl-" prefix (and internal definitions | |
1609 | use the "cl--" prefix). | |
7c1898a7 | 1610 | |
823b2fb6 GM |
1611 | If `cl' provided a feature under the name `foo', then `cl-lib' |
1612 | provides it under the name `cl-foo' instead; with the exceptions of the | |
1613 | few `cl' definitions that had to use `foo*' to avoid conflicts with | |
1614 | pre-existing Elisp entities. These have been renamed to `cl-foo' | |
1615 | rather than `cl-foo*'. | |
7c1898a7 | 1616 | |
92246540 | 1617 | The old `cl' is now deprecated and is mainly just a bunch of aliases that |
823b2fb6 | 1618 | provide the old, non-prefixed names. Some exceptions are listed below: |
7c1898a7 | 1619 | |
89660017 SM |
1620 | *** `cl-flet' is not like `flet' (which is deprecated). |
1621 | Instead it obeys the behavior of Common-Lisp's `flet'. | |
e8693c96 GM |
1622 | In particular, in cl-flet function definitions are lexically scoped, |
1623 | whereas in flet the scoping is dynamic. | |
89660017 SM |
1624 | |
1625 | *** `cl-labels' is slightly different from `labels'. | |
823b2fb6 GM |
1626 | The difference is that it relies on the `lexical-binding' machinery |
1627 | (as opposed to the `lexical-let' machinery used previously) to capture | |
1628 | definitions in closures, so such closures will only work if `lexical-binding' | |
1629 | is in use. | |
89660017 | 1630 | |
f94b04fc | 1631 | *** `cl-letf' is not exactly like `letf'. |
4ddedf94 GM |
1632 | The only difference is in details that relate to some deprecated usage |
1633 | of `symbol-function' in place forms. | |
f94b04fc | 1634 | |
89660017 | 1635 | *** `progv' was rewritten to use the `let' machinery. |
823b2fb6 GM |
1636 | A side effect is that variables without corresponding values are bound |
1637 | to nil rather than being made unbound. | |
89660017 | 1638 | |
9512f820 GM |
1639 | *** The following methods of extending `setf' are obsolete |
1640 | (use features from gv.el instead): | |
1641 | `define-modify-macro' (use `gv-letplace') | |
031b2ea7 GM |
1642 | `defsetf' (use `gv-define-simple-setter' or `gv-define-setter') |
1643 | `define-setf-expander' (use `gv-define-setter' or `gv-define-expander') | |
2b4da3ff | 1644 | `get-setf-method' no longer exists (see "Incompatible Lisp Changes") |
f94b04fc | 1645 | |
6bc66c10 | 1646 | ** Diff mode |
f938eda9 | 1647 | |
6bc66c10 GM |
1648 | *** Changes are now highlighted using the same color scheme as in |
1649 | modern VCSes. Deletions are displayed in red (new faces | |
1650 | `diff-refine-removed' and `smerge-refined-removed', and new definition | |
1651 | of `diff-removed'), insertions in green (new faces `diff-refine-added' | |
1652 | and `smerge-refined-added', and new definition of `diff-added'). | |
f938eda9 | 1653 | |
6bc66c10 GM |
1654 | *** The variable `diff-use-changed-face' defines whether to use the |
1655 | face `diff-changed', or `diff-removed' and `diff-added' to highlight | |
1656 | changes in context diffs. | |
2f940384 | 1657 | |
6bc66c10 GM |
1658 | *** The new command `diff-delete-trailing-whitespace' removes trailing |
1659 | whitespace introduced by a diff. | |
f938eda9 | 1660 | |
6bc66c10 GM |
1661 | ** Ediff now uses the same color scheme as Diff mode. |
1662 | ||
1663 | ** Python mode | |
1664 | ||
1665 | A new version of python.el, which provides several new features, including: | |
1666 | per-buffer shells, better indentation, Python 3 support, and improved | |
1667 | shell-interaction compatible with iPython (and virtually any other | |
1668 | text based shell). | |
1669 | ||
1670 | *** Some user options have been replaced/renamed, including (old -> new): | |
1671 | **** python-indent -> python-indent-offset | |

d5b1b1aa | 1681 | Comments are always considered as indentation markers. |
6bc66c10 GM |
1682 | |
1683 | **** `python-continuation-offset': Indentation is automatically | |
1684 | calculated in a pep8 compliant way depending on the context. | |
1685 | ||
1686 | **** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist': | |
1687 | Have no direct mapping as the shell interaction is completely different. | |
1688 | ||
1689 | **** `python-python-command', `python-jython-command': | |
1690 | Replaced by `python-shell-interpreter'. | |
1691 | ||
1692 | **** `inferior-python-filter-regexp', `python-remove-cwd-from-path', | |
1693 | `python-pdbtrack-minor-mode-string', `python-source-modes': | |
1694 | No longer relevant. | |

2f940384 | 1743 | |
f938eda9 CY |
1744 | *** `dired-do-async-shell-command' executes each file sequentially |

1746 | Otherwise, it executes the command on each file in parallel. | |
2f940384 | 1747 | |
823b2fb6 GM |
1748 | *** Typing `M-n' in the minibuffer of `dired-do-chmod', `dired-do-chgrp', |
1749 | `dired-do-chown', and `dired-do-touch' yanks the attributes of the | |
f938eda9 | 1750 | file at point. |
2f940384 | 1751 | |
f938eda9 | 1752 | *** When the region is active, `m' (`dired-mark'), `u' (`dired-unmark'), |
823b2fb6 | 1753 | `DEL' (`dired-unmark-backward'), and `d' (`dired-flag-file-deletion') |

2f940384 | 1755 | |
88c45e34 | 1756 | *** The minibuffer default for `=' (`dired-diff') has changed. |
f938eda9 CY |

6bc66c10 | 1834 | ** Apropos |
40d8bcb8 | 1835 | |
6bc66c10 GM |
1836 | *** The faces used by Apropos are now directly customizable. |
1837 | These faces are named `apropos-symbol', `apropos-keybinding', and so on; | |
1838 | see the `apropos' Custom group for details. | |
d13c8be6 | 1839 | |
6bc66c10 GM |
1840 | *** The old options whose values specified faces to use have been removed |
1841 | (i.e. `apropos-symbol-face', `apropos-keybinding-face', etc.). | |
d13c8be6 | 1842 | |
6bc66c10 | 1843 | ** Buffer Menu |
d13c8be6 | 1844 | |
6bc66c10 | 1845 | *** This package has been rewritten to use Tabulated List mode. |
d13c8be6 | 1846 | |
6bc66c10 GM |
1847 | *** Option `Buffer-menu-buffer+size-width' is now obsolete. |
1848 | Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead. | |
d13c8be6 | 1849 | |
86e100a6 GM |
1850 | ** Calc |
1851 | ||
1852 | *** Algebraic simplification mode is now the default. | |
1853 | To restrict to the limited simplifications given by the former | |
1854 | default simplification mode, use `m I'. | |
1855 | ||
6bc66c10 | 1856 | ** Calendar |
d13c8be6 | 1857 | |
6bc66c10 GM |
1858 | *** You can customize the header text that appears above each calendar month. |
1859 | See the variable `calendar-month-header'. | |
d13c8be6 | 1860 | |
6bc66c10 | 1861 | *** New LaTeX calendar style, produced by `cal-tex-cursor-week2-summary'. |
ee97deee | 1862 | |
6bc66c10 GM |
1863 | *** The calendars produced by cal-html include holidays. |
1864 | Customize `cal-html-holidays' to change this. | |
8b0823d6 | 1865 | |
0058cae2 GM |
1866 | ** CEDET |
1867 | ||
1868 | *** The major modes from the parser generators "Bovine" and "Wisent" | |
1869 | are now properly integrated in Emacs. The file suffixes ".by" and ".wy" | |
1870 | are in `auto-mode-alist', and the corresponding manuals are included. | |
1871 | ||
1872 | *** EDE | |
1873 | ||
1874 | **** Menu support for the "Configuration" feature. This allows users to | |
1875 | choose the active configuration (such as debug or install) from the menu. | |
1876 | ||
1877 | **** New command `ede-set' to interactively set project-local variables. | |
1878 | ||
1879 | **** Support for compiling, debugging, and running in "generic" projects. | |
1880 | ||
1881 | **** Autoconf editing support for M4 macros with complex arguments. | |
1882 | ||
1883 | **** Compilation support for the "linux" project type. | |

1886 | ||
1887 | *** Semantic | |
1888 | ||
1889 | **** Support for parsing #include statements inside a namespace in C/C++. | |
1890 | ||
1891 | **** Improved support for 'extern "C"' declarations in C/C++. | |
1892 | ||
1893 | **** The ability to ignore more common special C/C++ preprocessor symbols, | |
1894 | such as '__nonnull' and '__asm'. Add '__cplusplus' macro when parsing C++. | |
1895 | If available, include cdefs.h as an additional source of preprocessor symbols. | |
1896 | ||
1897 | **** Improved C/C++ function pointer parsing. | |
1898 | ||
1899 | **** In Python, support for converting imports to include file names. | |
1900 | ||
1901 | **** Ability to dynamically determine the Python load path. | |
1902 | ||
1903 | **** Support for the Python 'WITH' and 'AT' keywords. | |
1904 | ||
1905 | **** Improved tooltip completion. | |
1906 | ||
1907 | *** SRecode | |
1908 | ||
1909 | **** The SRecode manual is now included. | |
1910 | ||
1911 | **** Tag generation supports constructor/destructor settings and system | |
1912 | include differentiation. | |
1913 | ||
1914 | **** Addition of 'Framework' support: Frameworks are specified when a | |
1915 | particular kind of library (such as Android) is needed in a common language | |
1916 | mode (like Java). | |
1917 | ||
1918 | **** Support for nested templates and let variables override based on priority. | |
1919 | ||
1920 | **** Support for merging tables from multiple related modes, such as | |
1921 | default -> c++ -> arduino. | |

6bc66c10 | 1923 | ** Compile has a new option `compilation-always-kill'. |
42917e79 | 1924 | |
6bc66c10 | 1925 | ** Customize |
35d98877 | 1926 | |
6bc66c10 | 1927 | *** `custom-reset-button-menu' now defaults to t. |
35d98877 | 1928 | |
6bc66c10 GM |
1929 | *** Non-option variables are never matched in `customize-apropos' and |
1930 | `customize-apropos-options' (i.e., the prefix argument does nothing for | |
1931 | these commands now). | |
782fbf2a | 1932 | |
f938eda9 | 1933 | ** Term |
782fbf2a | 1934 | |
823b2fb6 GM |
1935 | *** The variables `term-default-fg-color' and `term-default-bg-color' |
1936 | are now deprecated in favor of the customizable face `term'. | |
fc72b15c | 1937 | |
02969baf GM |
1938 | *** You can customize how to display ANSI terminal colors and styles |
1939 | by customizing the corresponding `term-color-<COLOR>', | |
1940 | `term-color-underline' and `term-color-bold' faces. | |
cf20dee0 | 1941 | |
05ecb497 | 1942 | ** Tramp |
2f940384 | 1943 | |
02969baf | 1944 | *** The syntax has been extended in order to allow ad-hoc proxy definitions. |
05ecb497 | 1945 | |
823b2fb6 | 1946 | *** Remote processes are now also supported on remote MS-Windows hosts. |
05ecb497 | 1947 | |
ce7b18ec | 1948 | ** URL |
2f940384 | 1949 | |
ce7b18ec CY |
1950 | *** Structs made by `url-generic-parse-url' have nil `attributes' slot. |
1951 | Previously, this slot stored semicolon-separated attribute-value pairs | |
1952 | appended to some imap URLs, but this is not compatible with RFC 3986. | |
823b2fb6 | 1953 | So now the `filename' slot stores the entire path and query components, |
ce7b18ec | 1954 | and the `attributes' slot is always nil. |
2f940384 | 1955 | |
ce7b18ec CY |
1956 | *** New function `url-encode-url' for encoding a URI string. |
1957 | The `url-retrieve' function now uses this to encode its URL argument, | |
1958 | in case that is not properly encoded. | |
1959 | ||
6bc66c10 GM |
1960 | ** notifications.el supports now version 1.2 of the Notifications API. |
1961 | The function `notifications-get-capabilities' returns the supported | |
1962 | server properties. | |
f938eda9 | 1963 | |
6bc66c10 GM |
1964 | ** Flymake uses fringe bitmaps to indicate errors and warnings. |
1965 | See `flymake-fringe-indicator-position', `flymake-error-bitmap' and | |
1966 | `flymake-warning-bitmap'. | |
f938eda9 | 1967 | |
6bc66c10 GM |
1968 | ** The FFAP option `ffap-url-unwrap-remote' can now be a list of strings, |
1969 | specifying URL types that should be converted to remote file names at | |
1970 | the FFAP prompt. The default is now '("ftp"). | |
f938eda9 | 1971 | |
6bc66c10 GM |
1972 | ** New Ibuffer `derived-mode' filter, bound to `/ M'. |
1973 | The old binding for `/ M' (filter by used-mode) is now bound to `/ m'. | |
f938eda9 | 1974 | |
6bc66c10 GM |
1975 | ** New option `mouse-avoidance-banish-position' specifies where the |
1976 | `banish' mouse avoidance setting moves the mouse. | |
ce7b18ec | 1977 | |
6bc66c10 GM |
1978 | ** In Perl mode, new option `perl-indent-parens-as-block' causes non-block |
1979 | closing brackets to be aligned with the line of the opening bracket. | |
f938eda9 | 1980 | |
6bc66c10 | 1981 | ** In Proced mode, new command `proced-renice' renices marked processes. |
f938eda9 | 1982 | |
6bc66c10 GM |
1983 | ** New option `async-shell-command-buffer' specifies the buffer to use |
1984 | for a new asynchronous `shell-command' when the default output buffer | |
1985 | `*Async Shell Command*' is already in use. | |
f938eda9 | 1986 | |
6bc66c10 GM |
1987 | ** SQL mode has a new option `sql-db2-escape-newlines'. |
1988 | If non-nil, newlines sent to the command interpreter will be escaped | |
1989 | by a backslash. The default does not escape the newlines and assumes | |
1990 | that the sql statement will be terminated by a semicolon. | |
f938eda9 | 1991 | |
6bc66c10 GM |
1992 | ** New command `tabulated-list-sort', bound to `S' in Tabulated List mode |
1993 | (and modes that derive from it), sorts the column at point, or the Nth | |
1994 | column if a numeric prefix argument is given. | |
f938eda9 | 1995 | |
02969baf | 1996 | ** `which-func-modes' now defaults to t, so Which Function mode, when |
05b621a6 | 1997 | enabled, applies to all applicable major modes. |
f938eda9 | 1998 | |
6bc66c10 | 1999 | ** `winner-mode-hook' now runs when the mode is disabled, as well as when |
823b2fb6 | 2000 | it is enabled. |
f938eda9 | 2001 | |
6bc66c10 GM |
2002 | ** Follow mode no longer works by using advice. |
2003 | The option `follow-intercept-processes' has been removed. | |
2004 | ||
2005 | ** `javascript-generic-mode' is now an obsolete alias for `js-mode'. | |
f938eda9 | 2006 | |

6bc66c10 | 2031 | ** Obsolete packages |
2f940384 | 2032 | |
797e6e88 SM |
2033 | *** assoc.el |
2034 | In most cases, assoc+member+push+delq work just as well. | |
2035 | And in any case it's just a terrible package: ugly semantics, terrible | |
2036 | inefficiency, and not namespace-clean. | |

b4d3bc10 | 2046 | |
6bc66c10 GM |
2047 | ** Docstrings starting with `*' no longer indicate user options. |
2048 | Only variables defined using `defcustom' are considered user options. | |
2049 | The function `user-variable-p' is now an obsolete alias for | |
2050 | `custom-variable-p'. | |
090cf9db | 2051 | |
6bc66c10 GM |
2052 | ** The return values of `defalias', `defun' and `defmacro' have changed, |
2053 | and are now undefined. For backwards compatibility, `defun' and | |
2054 | `defmacro' currently return the name of the newly defined | |
2055 | function/macro, but this should not be relied upon. | |
090cf9db | 2056 | |
823b2fb6 GM |
2057 | ** `random' by default now returns a different random sequence in |
2058 | every Emacs run. Use `(random S)', where S is a string, to set the | |
0e23ef9d PE |
2059 | random seed to a value based on S, in order to get a repeatable |
2060 | sequence in later calls. | |
2061 | ||
d32e47af LM |
2062 | ** If the NEWTEXT arg to `replace-match' contains a substring "\?", |
2063 | that substring is inserted literally even if the LITERAL arg is | |
2064 | non-nil, instead of causing an error to be signaled. | |
2065 | ||
2cec368c MR |
2066 | ** `select-window' now always makes the window's buffer current. |
2067 | It does so even if the window was selected before. | |
2068 | ||
6bc66c10 GM |
2069 | ** The function `x-select-font' can return a font spec, instead of a |
2070 | font name as a string. Whether it returns a font spec or a font name | |
2071 | depends on the graphical library. | |
bbf908bc | 2072 | |
eeddc531 CY |
2073 | ** `face-spec-set' no longer sets frame-specific attributes when the |
2074 | third argument is a frame (that usage was obsolete since Emacs 22.2). | |
2075 | ||
6bc66c10 | 2076 | ** `set-buffer-multibyte' now signals an error in narrowed buffers. |
a59d531e | 2077 | |
ab7f1c43 GM |
2078 | ** The CL package's `get-setf-method' function no longer exists. |
2079 | Generalized variables are now part of core Emacs Lisp, and implemented | |
2080 | differently to the way cl.el used to do it. It is not possible to | |
2081 | define a compatible replacement for `get-setf-method'. See the file | |
2082 | gv.el for internal details of the new implementation. | |
2083 | ||
6bc66c10 GM |
2084 | ** The arguments of `dbus-register-signal' are no longer just strings, |
2085 | but keywords or keyword-string pairs. The old argument list will | |
2086 | still be supported for Emacs 24.x. | |
72b255c7 | 2087 | |
6bc66c10 | 2088 | ** Miscellaneous name changes |
823b2fb6 GM |
2089 | Some Lisp symbols have been renamed to correct their spelling, |
2090 | or to be more consistent with standard Emacs terminology. | |
72b255c7 | 2091 | |

ef24141c | 2137 | |
2ee3d7f0 | 2138 | ** CL-style generalized variables are now in core Elisp. |
f938eda9 | 2139 | `setf' is autoloaded; `push' and `pop' accept generalized variables. |
ebdbfb95 GM |
2140 | You can define your own generalized variables using `gv-define-simple-setter', |
2141 | `gv-define-setter', etc. | |
2ee3d7f0 | 2142 | |
6bc66c10 GM |
2143 | ** Emacs tries to macroexpand interpreted (non-compiled) files during load. |
2144 | This can significantly speed up execution of non-byte-compiled code, | |
2145 | but can also bump into previously unnoticed cyclic dependencies. | |
2146 | These are generally harmless: they will simply cause the macro calls | |
2147 | to be left for later expansion (as before), but will result in a | |
2148 | warning ("Eager macro-expansion skipped due to cycle") describing the cycle. | |
2149 | You may wish to restructure your code so this does not happen. | |
2150 | ||
2151 | ** New sampling-based Elisp profiler. | |
2152 | Try M-x profiler-start, do some work, and then call M-x profiler-report. | |
2153 | When finished, use M-x profiler-stop. The sampling rate can be based on | |
2154 | CPU time or memory allocations. | |
2155 | ||
500fcedc SM |
2156 | ** `defun' also accepts a (declare DECLS) form, like `defmacro'. |
2157 | The interpretation of the DECLS is determined by `defun-declarations-alist'. | |
2158 | ||
6bc66c10 GM |
2159 | ** New macros `setq-local' and `defvar-local'. |
2160 | ||
2161 | ** Face underlining can now use a wave. | |
2f940384 | 2162 | |
6bc66c10 | 2163 | ** `read-regexp' has a new argument HISTORY; the first argument PROMPT |
cd996018 | 2164 | of `read-regexp' accepts a string ending with a colon and space, and its |
823b2fb6 | 2165 | second argument DEFAULTS can be a list of strings accessible via `M-n' |
cd996018 CY |
2166 | in the minibuffer ahead of other hard-coded useful regexp-related values. |
2167 | More commands use `read-regexp' now to read their regexp arguments. | |
2168 | ||
f938eda9 | 2169 | ** Completion |
500fcedc | 2170 | |
f938eda9 CY |
2171 | *** New function `completion-table-with-quoting' to handle completion |
2172 | in the presence of quoting, such as file completion in shell buffers. | |
f95e9344 | 2173 | |
f938eda9 CY |
2174 | *** New function `completion-table-subvert' to use an existing completion |
2175 | table, but with a different prefix. | |
2176 | ||
6bc66c10 | 2177 | ** Debugger |
f95e9344 | 2178 | |
f938eda9 CY |
2179 | *** New error type and new function `user-error'. |
2180 | These do not trigger the debugger. | |
f95e9344 | 2181 | |
57fc0fee GM |
2182 | *** New option `debugger-bury-or-kill', saying what to do with the |
2183 | debugger buffer when exiting debug. | |

823b2fb6 GM |
2250 | functions that use this format, such as `file-attributes' and |

4e98ad15 | 2330 | ** Cygwin builds can use the native MS Windows user interface. |
823b2fb6 | 2331 | Pass `--with-w32' to configure. The default remains the X11 interface. |

1a9c6830 | 2333 | ** Two new functions are available in Cygwin builds: |
6e9f7997 DC |
2334 | `cygwin-convert-file-name-from-windows' and |
2335 | `cygwin-convert-file-name-to-windows'. These functions allow Lisp | |
2336 | code to access the Cygwin file-name mapping machinery to convert | |
2337 | between Cygwin and Windows-native file and directory names. | |

4e98ad15 | 2339 | ** When invoked with the -nw switch to run on the Windows text-mode terminal, |
1ab0c851 | 2340 | Emacs now supports `mouse-highlight', help-echo (in the echo area), and |
4e98ad15 GM |
2341 | `mouse-autoselect-window'. |
2342 | ||
1a9c6830 | 2343 | ** On MS Windows Vista and later Emacs now supports symbolic links. |
4e98ad15 | 2344 | |
823b2fb6 | 2345 | ** On MS Windows, you can pass `--without-libxml2' to configure.bat to omit |
4e98ad15 GM |
2346 | support for libxml2, even if its presence is detected. |
2347 | ||
4e98ad15 GM |
2348 | ** On Mac OS X, the Nextstep port requires OS X 10.4 or later. |

09e18d03 | 2360 | |
31fd3586 GM |
2361 | ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
2362 | to configure. Note that other libraries used by Emacs, RSVG and GConf, | |
2363 | also depend on Gtk+. You can disable them with --without-rsvg and | |
2364 | --without-gconf. | |
338648ad | 2365 | |
31fd3586 GM |
2366 | ** Emacs can be compiled with GnuTLS support. |
2367 | This happens by default if a suitably recent version of the library is | |
2368 | found at build time. To prevent this, use the configure option | |
2369 | `--without-gnutls'. See below for GnuTLS features. | |
338648ad | 2370 | |
31fd3586 GM |
2371 | ** Emacs can be compiled with SELinux support. |
2372 | This happens by default if a suitably recent version of the library is | |

31fd3586 GM |
2376 | ** Emacs can be compiled with ImageMagick support. |
2377 | This happens by default if a suitably recent version of the library is | |
2378 | found at build time. To prevent this, use the configure option | |
2379 | `--without-imagemagick'. See below for ImageMagick features. | |
c1f10868 | 2380 | This feature is not available for the Nextstep or MS ports. |

2386 | ||
7d301ae6 CY |
2387 | ** By default, the installed Info and man pages are compressed. |
2388 | You can disable this by configuring --without-compress-info. | |
2389 | ||
7d301ae6 | 2390 | ** New configure option --with-wide-int. |
81eafe29 | 2391 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. |
0a768890 PE |
2392 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB |
2393 | to about 2 GiB. | |
81eafe29 | 2394 | |
7d301ae6 | 2395 | ** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost. |
31fd3586 GM |
2396 | These provide no new functionality, they just remove the need to edit |
2397 | lib-src/Makefile by hand in order to use the associated features. | |
2398 | ||
7d301ae6 | 2399 | ** New configure option --enable-use-lisp-union-type. |
31fd3586 GM |
2400 | This is only useful for Emacs developers to debug certain types of bugs. |
2401 | This is not a new feature; only the configure flag is new. | |
041d709f CY |
2402 | |
2403 | ** The standalone programs digest-doc and sorted-doc are removed. | |
2404 | Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'. | |
2405 | ||
041d709f CY |
2406 | ** The standalone program `fakemail' is removed. |

2413 | command line arguments, and the EMACS_UNIBYTE environment variable, no |
2414 | longer have any effect. (They were declared obsolete in Emacs 23.) | |
198a7a97 | 2415 | |
66b7b0fe | 2416 | ** New command line option `--no-site-lisp' removes site-lisp directories |
1b5e5b0c GM |
2417 | from load-path. -Q now implies this. This option does not affect the |
2418 | EMACSLOADPATH environment variable (and hence has no effect for | |

fdeb32ec | 2425 | |
dfdb4cad CY |
2426 | *** Many packages now use the `completion-at-point' command, |
2427 | rather than implementing separate completion commands. | |
2428 | ||
de0bde62 | 2429 | *** `completion-at-point' now handles tags and semantic completion. |
dfdb4cad | 2430 | |
a2a25d24 SM |
2431 | *** Completion in a non-minibuffer now tries to detect the end of completion |
2432 | and pops down the *Completions* buffer accordingly. | |
dfdb4cad CY |
2433 | |
2434 | *** New option `completion-cycle-threshold' allows completion cycling. | |
2435 | ||
2436 | *** New option `completion-category-overrides' for overriding the | |
2c719188 | 2437 | default completion style in certain circumstances. |
dfdb4cad | 2438 | |
a2a25d24 | 2439 | *** New completion style `substring'. |
dfdb4cad CY |

2442 | ||
2443 | *** The option `widget-complete-field' has been removed. | |
620c53a6 | 2444 | |
6870aaef | 2445 | ** Mail changes |
dfdb4cad | 2446 | |
7d301ae6 CY |
2447 | *** The first time you try sending mail, Emacs asks for a mail method. |
2448 | This is implemented by a new default for `send-mail-function', which | |
2449 | is `sendmail-query-once'. This offers to use the smtpmail package, or | |
2450 | to use the old defaults relying on external mail facilities | |
2451 | (`sendmail-send-it' on GNU/Linux and other Unix-like systems, and | |
2452 | `mailclient-send-it' on Windows). | |
dfdb4cad | 2453 | |
e78e7e48 CY |
2454 | *** Typing `C-c m' in the buffer made by `M-x report-emacs-bug' |
2455 | transfers the report to your desktop's preferred mail client, if there | |
2456 | is one. This uses either the "xdg-email" utility, or Mac OS's "open" | |
2457 | command. | |
dfdb4cad | 2458 | |

dfdb4cad | 2465 | |
041d709f | 2466 | *** New emacsclient argument -q/--quiet suppresses some status messages. |
dfdb4cad | 2467 | |
7d301ae6 CY |
2468 | *** New emacsclient argument --frame-parameters specifies the frame |
2469 | parameters of any newly-created graphical frame. | |
dfdb4cad CY |
2470 | |
2471 | *** If emacsclient shuts down due to Emacs signaling an error, | |
2472 | its exit status is 1. | |
2473 | ||
041d709f CY |
2474 | *** New emacsclient argument --parent-id ID. |
2475 | This opens a client frame in parent X window ID, via XEmbed, similar | |
2476 | to the --parent-id argument to Emacs. | |
2477 | ||
d0ce9f8c MB |
2478 | ** Internationalization changes |
2479 | ||
d0ce9f8c | 2480 | *** Emacs now supports display and editing of bidirectional text. |
7d301ae6 CY |
2481 | Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are |
2482 | displayed in the correct visual order as expected by users of those | |
dfdb4cad CY |
2483 | scripts. The display reordering is a "full bidirectionality" class |
2484 | implementation of the Unicode Bidirectional Algorithm (UBA). Buffers | |
2485 | with no RTL text should look exactly the same as before. | |
f4b6ba46 | 2486 | |
041d709f | 2487 | **** New buffer-local variable `bidi-display-reordering'. |
7d301ae6 | 2488 | To disable display reordering in a buffer, change this to nil. |
d20e1419 | 2489 | |
041d709f CY |
2490 | **** New buffer-local variable `bidi-paragraph-direction'. |
2491 | If nil (the default), Emacs determines the base direction of each | |
dfdb4cad CY |
2492 | paragraph from its text, as specified by the UBA. Setting the value |
2493 | to `right-to-left' or `left-to-right' forces a base direction on each | |
2494 | paragraph. | |
f4b6ba46 | 2495 | |
7d301ae6 CY |
2496 | Paragraphs with right-to-left base direction are displayed starting at |
2497 | the right window edge. | |
f1816485 | 2498 | |
dfdb4cad CY |
2499 | *** Enhanced support for characters with no glyphs in available fonts, |
2500 | or, on text terminals, characters that cannot be encoded by the | |
2501 | terminal coding system. The new option `glyphless-char-display-control' | |
2502 | specifies how to display them: as a hexadecimal code in a box, a thin | |
2503 | 1-pixel space, an empty box, etc. | |
d0ce9f8c | 2504 | |
9702b7a1 GM |
2505 | *** New input methods for Farsi and Bulgarian |
2506 | (farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic). | |
041d709f | 2507 | |
939db9ac CY |
2508 | *** `nobreak-char-display' now also highlights Unicode hyphen chars |
2509 | (U+2010 and U+2011). | |
2510 | ||
7d301ae6 | 2511 | *** New Hebrew translation of the Emacs Tutorial. |
31fd3586 GM |
2512 | Type `C-u C-h t' to choose it in case your language setup doesn't |
2513 | automatically select it. | |
2514 | ||
7d301ae6 CY |
2515 | ** An Emacs Lisp package manager is now included. |
2516 | This is a convenient way to download and install additional packages, | |
2517 | from a package repository at http://elpa.gnu.org. | |
dfdb4cad | 2518 | |
7d301ae6 CY |
2519 | *** M-x list-packages shows a list of packages, which can be |
2520 | selected for installation. | |
dfdb4cad | 2521 | |
7d301ae6 | 2522 | *** New command `describe-package', bound to `C-h P'. |
dfdb4cad | 2523 | |
7d301ae6 CY |
2524 | *** By default, all installed packages are loaded automatically when |
2525 | Emacs starts up. To disable this, set `package-enable-at-startup' to | |
2526 | nil. To specify the packages to load, customize `package-load-list'. | |

dfdb4cad CY |
2528 | ** Custom theme changes |
2529 | ||
7d301ae6 CY |
2530 | *** New command `M-x customize-themes', which provides a convenient |
2531 | interface for enabling and disabling Custom themes. | |
dfdb4cad | 2532 | |
7d301ae6 | 2533 | *** New option `custom-theme-load-path' is the load path for themes. |
dfdb4cad CY |
2534 | Emacs no longer looks for Custom themes in `load-path'. The default |
2535 | value of `custom-theme-load-path' says to look for themes in | |
2536 | `custom-theme-directory', followed by a subdirectory of | |
2537 | `data-directory' named "themes/", which contains a small selection of | |
2538 | built-in Custom themes. | |
2539 | ||
7d301ae6 CY |
2540 | *** New option `custom-safe-themes' records known-safe theme files. |
2541 | If a theme is not in this list, Emacs queries before loading it, and | |
2542 | offers to save the theme to `custom-safe-themes' automatically. By | |
2543 | default, all themes included in Emacs are treated as safe. | |
b7d65a5f | 2544 | |
7d301ae6 | 2545 | ** Improved GTK integration |
dfdb4cad | 2546 | |
7d301ae6 | 2547 | *** GTK scroll-bars are now placed on the right by default. |
dfdb4cad CY |
2548 | The function `set-scroll-bar-mode' can change this. |
2549 | ||
7d301ae6 | 2550 | *** GTK tool bars can have just text, just images or images and text. |
dfdb4cad CY |
2551 | Customize `tool-bar-style' to choose the style. On a Gnome desktop, |
2552 | the default is taken from desktop settings. | |
2553 | ||
2554 | *** GTK tool bars can be placed on any edge of the frame. | |
7d301ae6 CY |
2555 | The frame-parameter tool-bar-position controls this. It takes the |
2556 | values top, left, right or bottom. The Options => Show/Hide menu has | |
2557 | entries for this. | |
dfdb4cad | 2558 | |
7d301ae6 CY |
2559 | *** The default colors for selected text (the `region' face) are taken |
2560 | from the GTK theme when Emacs is built with GTK. | |
dfdb4cad | 2561 | |
7d301ae6 CY |
2562 | *** Emacs uses GTK tooltips by default if built with GTK. |
2563 | You can disable this by changing `x-gtk-use-system-tooltips' to nil. | |
a5bee597 | 2564 | |
dfdb4cad CY |
2565 | ** Graphical interface changes |
2566 | ||
2567 | *** On graphical displays, the mode-line no longer ends in dashes. | |
2568 | Also, the first dash (which does not indicate anything) is just | |
2569 | displayed as a space. | |
2570 | ||
2571 | *** `menu-bar-select-buffer-function' lets you choose another operation | |
2572 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. | |
2573 | ||
2574 | *** Lucid menus and dialogs can display antialiased fonts if Emacs is | |
2575 | built with Xft. These fonts can be set via X resources, for example: | |
2576 | Emacs.pane.menubar.font: Courier-12 | |
2577 | ||
7d301ae6 | 2578 | ** Exiting changes |
dfdb4cad | 2579 | |
7d301ae6 | 2580 | *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP, |
dfdb4cad CY |
2581 | or if it receives a SIGINT signal in batch mode. |
2582 | ||
7d301ae6 CY |
2583 | *** `kill-emacs-hook' is now also run in batch mode. |
2584 | Third-party code which adds to `kill-emacs-hook' should check if they | |
2585 | do the right thing in batch mode. | |
9c524fcb | 2586 | |
041d709f | 2587 | ** Scrolling changes |
dfdb4cad | 2588 | |
041d709f | 2589 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' |
0a19a6f8 | 2590 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
7d301ae6 | 2591 | of buffer at first key-press (instead they move to top/bottom of buffer) |
550f41cd | 2592 | when `scroll-error-top-bottom' is non-nil. |
dfdb4cad CY |
2593 | |
2594 | *** New option `scroll-error-top-bottom' (see above). | |
2595 | ||
041d709f | 2596 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' |
5a97d2da | 2597 | scroll a line instead of full screen. |
dfdb4cad | 2598 | |
041d709f | 2599 | *** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 2600 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
dfdb4cad | 2601 | |
041d709f | 2602 | *** If you customize `scroll-conservatively' to a value greater than 100, |
d0f69533 EZ |
2603 | Emacs will never recenter point in the window when it scrolls due to |
2604 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | |
2605 | Previously, you needed to use `most-positive-fixnum' as the value of | |
2606 | `scroll-conservatively' to achieve the same effect. | |
dfdb4cad | 2607 | |
7d301ae6 | 2608 | *** "Aggressive" scrolling now honors the scroll margins. |
d0f69533 EZ |
2609 | If you customize `scroll-up-aggressively' or |
2610 | `scroll-down-aggressively' and move point off the window, Emacs now | |
2611 | scrolls the window so as to avoid positioning point inside the scroll | |
2612 | margin. | |
2613 | ||
7d301ae6 CY |
2614 | ** Basic SELinux support has been added. |
2615 | This requires Emacs to be linked with libselinux at build time. | |
f1a5d776 | 2616 | |
dfdb4cad CY |
2617 | *** Emacs preserves the SELinux file context when backing up. |
2618 | Also, the function `copy-file' has an extra optional argument for | |
2619 | preserving SELinux context, and the return value of `backup-buffer' | |
2620 | now includes the SELinux context. | |
f0bf7c8e | 2621 | |
dfdb4cad | 2622 | *** New functions `file-selinux-context' and `set-file-selinux-context' |
7d301ae6 | 2623 | get and set the SELinux context of a file. |
44198b6e | 2624 | |
7d301ae6 | 2625 | ** Trash changes |
dfdb4cad | 2626 | |
7d301ae6 CY |
2627 | *** `delete-by-moving-to-trash' now only affects commands that specify |
2628 | trashing. This avoids inadvertently trashing temporary files. | |
dfdb4cad | 2629 | |
7d301ae6 CY |
2630 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
2631 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
278f6845 | 2632 | |
041d709f | 2633 | ** File- and directory-local variable changes |
dfdb4cad | 2634 | |
041d709f CY |
2635 | *** You can stop directory local vars from applying to subdirectories. |
2636 | Add an element (subdirs . nil) to the alist portion of any variables | |
2637 | settings to indicate that the section should not apply to | |
2638 | subdirectories. | |
dfdb4cad | 2639 | |
041d709f CY |
2640 | *** Directory local variables can apply to some file-less buffers. |
2641 | Affected modes include dired, vc-dir, and log-edit. For example, | |
2642 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will | |
2643 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call | |
2644 | `hack-dir-local-variables-non-file-buffer' to support this. | |
dfdb4cad | 2645 | |
041d709f CY |
2646 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. |
2647 | Instead, use "eval: (minor-mode 1)". | |
c136e5cd | 2648 | |
7b447e9b GM |
2649 | *** The variable `inhibit-first-line-modes-regexps' has been renamed |
2650 | to `inhibit-local-variables-regexps'. As the name suggests, it now | |
dfdb4cad CY |
2651 | applies to ALL file local variables, not just -*- lines. The |
2652 | associated `inhibit-first-line-modes-suffixes' has been renamed in the | |
2653 | corresponding way. | |
5d907d6c | 2654 | |
0a2132ba CY |
2655 | ** Window changes |
2656 | ||
91b65361 CY |
2657 | *** The `quit-window' command now restores the last buffer displayed |
2658 | in the quitted window. | |
2659 | ||
0a2132ba CY |
2660 | *** Resizing an Emacs frame now preserves proportional window sizes, |
2661 | modulo restrictions like window minimum sizes and fixed-size windows. | |
2662 | ||
2663 | *** The behavior of `display-buffer' is now customizable in detail. | |
dfdb4cad | 2664 | |
0a2132ba CY |
2665 | **** New option `display-buffer-base-action' specifies a list of |
2666 | user-determined display "actions" (functions and optional arguments | |
2667 | for choosing the displaying window). | |
2668 | ||
2669 | This takes precedence over the default display action, which is | |
2670 | specified by `display-buffer-fallback-action'. | |
2671 | ||
2672 | **** New option `display-buffer-alist' maps buffer name regexps to | |
2673 | display actions, taking precedence over `display-buffer-base-action'. | |
2674 | ||
a0c2d0ae MR |
2675 | *** New option `window-combination-limit'. |
2676 | The new option `window-combination-limit' allows to return the space | |
2677 | obtained for resizing or creating a window more reliably to the window | |
2678 | from which such space was obtained. | |
0a2132ba | 2679 | |
a0c2d0ae MR |
2680 | *** New option `window-combination-resize'. |
2681 | The new option `window-combination-resize' allows to split a window that | |
2682 | otherwise cannot be split because it's too small by stealing space from | |
2683 | other windows in the same combination. Subsequent resizing or deletion | |
2684 | of the window will resize all windows in the same combination as well. | |
0a2132ba | 2685 | |
91b65361 CY |
2686 | *** New option `frame-auto-hide-function' lets you choose between |
2687 | iconifying or deleting a frame when burying a buffer in a dedicated | |
2688 | frame, or quitting a window showing a buffer in a frame of its own. | |
2689 | ||
0a2132ba | 2690 | *** New commands `maximize-window' and `minimize-window'. |
53964682 | 2691 | These maximize and minimize the size of a window within its frame. |
0a2132ba | 2692 | |
0a2132ba CY |
2693 | *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'. |
2694 | These functions allow to navigate through the live buffers that have | |
2695 | been shown in a specific window. | |
2696 | ||
7d301ae6 | 2697 | ** Minibuffer changes |
dfdb4cad | 2698 | |
7d301ae6 | 2699 | *** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. |
104dc9c6 GM |
2700 | This is handy for minibuffer-only frames, and is also used for the feature |
2701 | where mouse-1 pops up *Messages*"', which can now easily be changed. | |
041d709f | 2702 | |
7d301ae6 | 2703 | *** Minibuffers set `truncate-lines' to nil. |
f66eca26 | 2704 | If you want to change the value to something else, you could use |
7d301ae6 CY |
2705 | for example `minibuffer-setup-hook'. |
2706 | ||
7d301ae6 CY |
2707 | ** `auto-mode-case-fold' is now enabled by default. |
2708 | ||
7d301ae6 | 2709 | ** `backup-by-copying-when-mismatch' now defaults to t. |
f66eca26 | 2710 | |
dfdb4cad CY |
2711 | ** New basic faces `error', `warning', `success'. |
2712 | These are used to highlight text indicating failure, caution or | |
2713 | successful operation. | |
2714 | ||
2715 | ** New option `list-colors-sort' defines the color sort order | |
2716 | for `list-colors-display'. | |
2717 | ||
2718 | ** The variable `focus-follows-mouse' now always defaults to nil. | |

eb199145 | 2721 | * Editing Changes in Emacs 24.1 |
b350bdf2 | 2722 | |
892777ba | 2723 | ** Search changes |
dfdb4cad CY |
2724 | |
2725 | *** C-y in Isearch is now bound to `isearch-yank-kill', instead of | |
2726 | `isearch-yank-line'. | |
2727 | ||
2728 | *** M-y in Isearch is now bound to `isearch-yank-pop', instead of | |
2729 | `isearch-yank-kill'. | |
2730 | ||
2731 | *** M-s C-e in Isearch is now bound to `isearch-yank-line'. | |
2732 | ||
b2b0776e | 2733 | ** New commands `count-words-region' and `count-words'. |
dfdb4cad | 2734 | |
10607bea CY |
2735 | *** M-= is bound to `count-words-region', not `count-lines-region'. |
2736 | The `count-words-region' command, when called interactively, reports | |
2737 | the number of lines, words, and characters in the region. It is a | |
2738 | superset of the old `count-lines-region', which is now an obsolete | |
2739 | alias for it. | |
ea4f7750 | 2740 | |
ec9da840 | 2741 | ** The command `just-one-space' (M-SPC), if given a negative argument, |
1c708c1a CY |
2742 | also deletes newlines around point. |
2743 | ||
b9229673 | 2744 | ** Deletion changes |
dfdb4cad | 2745 | |
b9229673 | 2746 | *** New option `delete-active-region'. |
ddb54206 | 2747 | If non-nil, [delete] and DEL delete the region if it is active and no |
dfdb4cad | 2748 | prefix argument is given. If set to `kill', those commands kill |
ddb54206 | 2749 | instead. |
dfdb4cad | 2750 | |
59ee0542 | 2751 | *** New command `delete-forward-char', bound to [delete]. |
42d9cffa CY |
2752 | This is meant for interactive use, and obeys `delete-active-region'. |
2753 | The command `delete-char' does not obey `delete-active-region'. | |
dfdb4cad | 2754 | |
b9229673 CY |
2755 | *** `delete-backward-char' is now a Lisp function. |
2756 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
7d301ae6 CY |
2757 | However, the byte compiler now warns if it is called from Lisp; Lisp |
2758 | callers should use delete-char with a negative argument instead. | |
dfdb4cad | 2759 | |
b9229673 CY |
2760 | *** The option `mouse-region-delete-keys' has been deleted. |
2761 | ||
f9d71b42 CY |
2762 | ** Selection changes. |
2763 | ||
7d301ae6 CY |
2764 | The default handling of clipboard and primary selections has been |
2765 | changed to conform with modern X applications. In short, most | |
2766 | commands for killing and yanking text now use the clipboard, while | |
2767 | mouse commands use the primary selection. | |
b1ab31ae CY |
2768 | |
2769 | In the following, we provide a list of these changes, followed by a | |
2770 | list of steps to get the old behavior back if you prefer that. | |
2771 | ||
b1ab31ae CY |
2772 | *** `select-active-regions' now defaults to t. |
2773 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
963578d3 | 2774 | the kill ring. The selected text is put in the primary selection, if |
b1ab31ae CY |
2775 | the system possesses a separate primary selection facility (e.g. X). |
2776 | ||
2777 | **** `select-active-regions' also accepts a new value, `only'. | |
2778 | This means to only set the primary selection for temporarily active | |
2779 | regions (usually made by mouse-dragging or shift-selection); | |
2780 | "ordinary" active regions, such as those made with C-SPC followed by | |
2781 | point motion, do not alter the primary selection. | |
2782 | ||
963578d3 CY |
2783 | **** `mouse-drag-copy-region' now defaults to nil. |
2784 | ||
b1ab31ae CY |
2785 | *** mouse-2 is now bound to `mouse-yank-primary'. |
2786 | This pastes from the primary selection, ignoring the kill-ring. | |
2787 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
dfdb4cad | 2788 | |
b1ab31ae | 2789 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
dfdb4cad | 2790 | |
b1ab31ae CY |
2791 | *** `x-select-enable-primary' now defaults to nil. |
2792 | Thus, commands that kill text or copy it to the kill-ring (such as | |
2793 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
2794 | ||
2795 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now | |
dfdb4cad | 2796 | exactly equivalent to M-w, C-w, and C-y respectively. |
b1ab31ae CY |
2797 | |
2798 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already | |
2799 | non-nil by default, as Windows does not support the primary selection | |
2800 | between applications. | |
2801 | ||
2802 | *** To return to the previous behavior, do the following: | |
dfdb4cad | 2803 | |
104c2fe9 | 2804 | **** Change `select-active-regions' to nil. |
b1ab31ae CY |
2805 | **** Change `mouse-drag-copy-region' to t. |
2806 | **** Change `x-select-enable-primary' to t (on X only). | |
2807 | **** Change `x-select-enable-clipboard' to nil. | |
2808 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 2809 | |
084e6df3 | 2810 | *** Support for X cut buffers has been removed. |
dfdb4cad | 2811 | |
3fd50d5c CY |
2812 | *** X clipboard managers are now supported. |
2813 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. | |
4b80f674 | 2814 | |
dfdb4cad CY |
2815 | ** New command `C-x r N' (`rectangle-number-lines') numbers the lines |
2816 | in the current rectangle. With a prefix argument, this prompts for a | |
2817 | number to count from and for a format string. | |
99f053cf | 2818 | |
7d301ae6 | 2819 | ** `redisplay-dont-pause' now defaults to t. |
6bf7006f EZ |
2820 | This makes Emacs feel more responsive to editing commands that arrive |
2821 | at high rate, e.g. if you lean on some key, because stopping redisplay | |
2822 | in the middle (when this variable is nil) forces more expensive | |
2823 | updates later on, and Emacs appears to be unable to keep up. | |
2824 | ||
e70b5064 CY |
2825 | ** The behavior of <TAB> for active regions in Text mode has changed. |
2826 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | |
2827 | when the region is active causes Emacs to indent all the lines in the | |
2828 | region, aligning them with the line previous to the first line in the | |
2829 | region (or with the left margin if there is no previous line). | |
2830 | ||
dfdb4cad CY |
2831 | ** When `occur' is called with a prefix argument, matching strings are |
2832 | collected into the `*Occur*' buffer without line numbers. If there | |
2833 | are parenthesized subexpressions in the specified regexp, `occur' | |
2834 | reads replacement text that may contain \\& and \\N whose convention | |
2835 | follows `replace-match'. | |

7d301ae6 CY |
2859 | *** The default browser used by the package is now the "xdg-open" program, |
2860 | on platforms that support it. This calls your desktop's preferred browser. | |

2875 | *** New "O" option prefix. | |
2876 | ||
2877 | *** Use the "O" prefix to "d r" (`calc-radix') to turn on twos-complement mode. | |
2878 | ||
cf16af42 GM |
2879 | ** Calendar, Diary, and Appt |
2880 | ||
7d301ae6 | 2881 | *** Diary entries can contain non-printing "comments". |
548d0a63 GM |
2882 | See the variable `diary-comment-start'. |
2883 | ||
5006e634 GM |
2884 | *** Appointments can specify their individual warning times. |
2885 | See the variable `appt-warning-time-regexp'. | |
2886 | ||
0a2bb1a9 GM |
2887 | *** The function specified by `appt-disp-window-function' may be passed |
2888 | lists of arguments if multiple appointments are due at similar times. | |
2889 | If you are using a custom function for this, you should update it. | |
2890 | ||
7454f200 GM |
2891 | *** New function `diary-hebrew-birthday'. |
2892 | ||
e565dd37 GM |
2893 | *** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array' |
2894 | may no longer be nil, but must all be strings. | |
2895 | ||
7d301ae6 CY |
2896 | *** The obsolete (since Emacs 22.1) method of enabling the appt |
2897 | package by adding `appt-make-list' to `diary-hook' has been removed. | |
2898 | Use `appt-activate' instead. | |
cf16af42 | 2899 | |
cf16af42 GM |
2900 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: |
2901 | appt-issue-message (use the function appt-activate) | |
2902 | appt-visible/appt-msg-window (use the variable appt-display-format) | |
2903 | ||
cf16af42 GM |
2904 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: |
2905 | view-diary-entries, list-diary-entries, show-all-diary-entries | |
2906 | ||
551b046f | 2907 | ** CC Mode |
dfdb4cad | 2908 | |
551b046f | 2909 | *** New feature to "guess" the style in an existing buffer. |
7d301ae6 | 2910 | The main entry point is M-x c-guess. |
041d709f | 2911 | |
551b046f AM |
2912 | *** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang). |
2913 | ||
dfdb4cad | 2914 | *** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes. |
551b046f AM |
2915 | Thus C-M-a will, by default, go to the beginning of the immediate function, |
2916 | not the top level. | |
2917 | ||
dfdb4cad | 2918 | *** "Macros with semicolons" can be registered for correct indentation. |
551b046f AM |
2919 | Where such a macro ends a line (no semicolon) the next statement is no longer |
2920 | parsed as a statement continuation. | |
2921 | ||
dfdb4cad | 2922 | ** Comint and modes derived from it use the standard completion code. |
041d709f CY |
2923 | |
2924 | ** Compilation mode | |
dfdb4cad | 2925 | |
7d301ae6 | 2926 | *** Compilation mode can be used without Font Lock mode. |
041d709f CY |
2927 | `compilation-parse-errors-function' is now obsolete. |
2928 | ||
dfdb4cad | 2929 | *** New variable `compilation-filter-start', which is bound while |
7d301ae6 CY |
2930 | `compilation-filter-hook' runs. It records the start position of the |
2931 | text inserted by `compilation-filter'. | |
041d709f | 2932 | |
47a6a35f GM |
2933 | *** `compilation-error-screen-columns' and `compilation-first-column' |
2934 | are obeyed in the editing buffer. So programming language modes can | |
7d301ae6 CY |
2935 | set them, whereas previously only the value in the *Compilation* |
2936 | buffer was used. | |
1dce7193 | 2937 | |
52834b6b CY |
2938 | ** Customize |
2939 | ||
2940 | *** Customize buffers now contain a search field. | |
2941 | The search is performed using `customize-apropos'. | |
7d301ae6 | 2942 | To turn off the search field, set `custom-search-field' to nil. |
52834b6b | 2943 | |
8d5dd370 | 2944 | *** Options in customize group buffers start out hidden if not customized. |
52834b6b CY |
2945 | Use the arrow to the left of the option name to toggle visibility. |
2946 | ||
2947 | *** custom-buffer-sort-alphabetically now defaults to t. | |
2948 | ||
2949 | *** The color widget now has a "Choose" button, which allows you to | |
7d301ae6 | 2950 | choose a color via `list-colors-display'. |
52834b6b | 2951 | |
041d709f CY |
2952 | ** D-Bus |
2953 | ||
5da3be7f GM |
2954 | *** It is now possible to access buses other than the default system |
2955 | or session bus. | |
041d709f | 2956 | |
7d301ae6 | 2957 | *** The `dbus-register-method' and `dbus-register-property' functions |
5da3be7f | 2958 | optionally do not register names. |
041d709f | 2959 | |
7d301ae6 | 2960 | *** The new function `dbus-register-service' registers a known service |
dfdb4cad | 2961 | name on a D-Bus without also registering a property or a method. |
041d709f | 2962 | |
f5d6548a | 2963 | ** Dired-x |
425a25f1 | 2964 | |
7d301ae6 CY |
2965 | *** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'), |
2966 | if called with a prefix argument, read a file name from the minibuffer | |
2967 | instead of using the current buffer. | |
f5d6548a | 2968 | |
7d301ae6 | 2969 | *** The "dired local variables" feature of Dired-x is obsolete. |
817b48a7 | 2970 | The standard directory local variables feature replaces it. |
8117868f | 2971 | |
041d709f | 2972 | ** ERC changes |
7492acc9 | 2973 | |
c4077254 GM |
2974 | *** New options `erc-autojoin-timing' and `erc-autojoin-delay', |
2975 | controlling attempts to autojoin a channel. | |
041d709f CY |
2976 | |
2977 | *** New variable `erc-coding-system-precedence': If we use `undecided' | |
2978 | as the server coding system, this variable will then be consulted. | |
2979 | The default is to decode strings that can be decoded as utf-8 as | |
2980 | utf-8, and do the normal `undecided' decoding for the rest. | |
7492acc9 | 2981 | |
041d709f | 2982 | ** Eshell changes |
7492acc9 | 2983 | |
05f77e38 GM |
2984 | *** The default value of `eshell-directory-name' has changed |
2985 | to be an "eshell" directory in `user-emacs-directory'. | |
2986 | The old "~/.eshell/" directory is still used if it exists, though. | |
041d709f CY |
2987 | |
2988 | ** gdb-mi | |
dfdb4cad CY |
2989 | |
2990 | *** The M-x gdb command now uses the GDB Machine Interface protocol. | |
05f77e38 GM |
2991 | It now supports multithread non-stop debugging and simultaneous |
2992 | debugging of several threads. | |
7492acc9 | 2993 | |
18af70d0 CY |
2994 | ** Image mode |
2995 | ||
05f77e38 GM |
2996 | *** RET (`image-toggle-animation') toggles animation, if applicable. |
2997 | Animation plays once, unless the option `image-animate-loop' is non-nil. | |
18af70d0 | 2998 | |
041d709f | 2999 | ** Info |
723ee192 | 3000 | |
7d301ae6 | 3001 | *** New command M-x info-display-manual displays a named Info manual. |
2ebc3b94 GM |
3002 | If that manual is already visited in some Info buffer, it displays |
3003 | that buffer. (This is handy if you have many manuals in many *info* | |
3004 | buffers, and don't remember the name of the buffer visiting the manual | |
3005 | you want to consult.) Otherwise, it loads and displays the manual. | |
691cf4a0 | 3006 | |
24ea72d3 EZ |
3007 | *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'. |
3008 | This is for compatibility with the stand-alone Info reader program, | |
3009 | and also because `Info-edit' is a rarely used command that is disabled | |
3010 | by default. | |
3011 | ||
7d301ae6 | 3012 | ** Mail mode changes (not Message mode) |
dfdb4cad | 3013 | |
7d301ae6 | 3014 | *** New command M-x mail-add-attachment for adding MIME attachments |
7d301ae6 | 3015 | |
dfdb4cad CY |
3016 | *** The command M-x mail-attach-file was renamed to M-x mail-insert-file. |
3017 | (Its name is misleading, since it has nothing to do with MIME | |
3018 | attachments.) The old name is now an obsolete alias to the new name. | |
3019 | ||
f2c3a9eb | 3020 | ** MH-E has been updated to MH-E version 8.3.1. |
041d709f | 3021 | See MH-E-NEWS for details. |
37221432 | 3022 | |
041d709f | 3023 | ** Modula-2 mode provides auto-indentation. |
37221432 | 3024 | |
041d709f | 3025 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
3c3d4f5b | 3026 | |
5d1ac394 | 3027 | ** nXML mode no longer binds C-RET to `nxml-complete'. |
dfdb4cad CY |
3028 | Completion is now performed via `completion-at-point', bound to C-M-i |
3029 | or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the | |
3030 | default), this performs tag completion. | |
5d1ac394 | 3031 | |
f2c3a9eb CY |
3032 | ** Org mode has been updated to version 7.8.09. |
3033 | See ORG-NEWS for details. | |
3034 | ||
041d709f | 3035 | ** Prolog mode has been completely revamped, with lots of additional |
7d301ae6 CY |
3036 | functionality such as more intelligent indentation, electricity, |
3037 | support for more variants, including Mercury, and a lot more. | |
041d709f CY |
3038 | |
3039 | ** Rmail | |
3040 | ||
3041 | *** The command `rmail-epa-decrypt' decrypts OpenPGP data | |
3042 | in the Rmail incoming message. | |
3043 | ||
50419064 GM |
3044 | *** The variable `rmail-message-filter' no longer has any effect. |
3045 | This change was made in Emacs 23.1 but was not advertised at the time. | |
3046 | Try using `rmail-show-message-hook' instead. | |
3047 | ||
717a1362 | 3048 | ** Shell mode |
dfdb4cad CY |
3049 | |
3050 | *** M-x shell prompts for the shell path name if the default directory | |
3051 | is a remote file name and neither the environment variable $ESHELL nor | |
3052 | the variable `explicit-shell-file-name' is set. | |
3053 | ||
3054 | *** TAB is now bound to the standard `completion-at-point' command, | |
3055 | which now implements the pcomplete rules for shell command completion. | |
717a1362 | 3056 | |
7d301ae6 CY |
3057 | ** SMTPmail |
3058 | ||
dfdb4cad | 3059 | *** SMTPmail now uses encrypted connections (via STARTTLS) by default |
7d301ae6 CY |
3060 | if the mail server supports them. This uses either built-in GnuTLS |
3061 | support, or the starttls.el library. Customize `smtpmail-stream-type' | |
3062 | to change this. | |
3063 | ||
7d301ae6 CY |
3064 | *** The variable `smtpmail-auth-credentials' has been removed. |
3065 | By default, the information is now stored in the file ~/.authinfo. | |
dfdb4cad CY |
3066 | This was the default value of smtpmail-auth-credentials. If you had |
3067 | customized smtpmail-auth-credentials to a list of user names and | |
3068 | passwords, those settings are not used. During your first connection | |
3069 | to the smtp server, Emacs will prompt for the user name and password, | |
3070 | and offer to save them to ~/.authinfo. Or you can manually copy the | |
3071 | credentials to ~/.authinfo. For example, if you had | |
7d301ae6 CY |
3072 | |
3073 | (setq smtpmail-auth-credentials | |
3074 | '(("mail.example.org" 25 "jim" "s!cret"))) | |
3075 | ||
3076 | then the equivalent line in ~/.authinfo would be | |
3077 | ||
3078 | machine mail.example.org port 25 login jim password s!cret | |
3079 | ||
3080 | See the auth-source manual for more information, e.g. on encrypting | |
3081 | the credentials file. | |
3082 | ||
7d301ae6 | 3083 | *** The variable `smtpmail-starttls-credentials' has been removed. |
dfdb4cad | 3084 | If you had that set, you need to put |
7d301ae6 CY |
3085 | |
3086 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert" | |
3087 | ||
3088 | in your ~/.authinfo file instead. | |
3089 | ||
8ce192e3 LI |
3090 | *** SMTPmail defaults to using the address in the From: header as the |
3091 | SMTP MAIL FROM envelope. To override this, set `mail-envelope-from' | |
3092 | to the address you wish to use instead. | |
3093 | ||
34e8a2da | 3094 | ** SQL mode |
041d709f | 3095 | |
34e8a2da GM |
3096 | *** New options `sql-port', `sql-connection-alist', `sql-send-terminator', |
3097 | and `sql-oracle-scan-on'. | |
041d709f | 3098 | |
dfdb4cad | 3099 | *** New options controlling prompting for login parameters. |
34e8a2da GM |
3100 | Each supported product has a custom variable `sql-*-login-params', |
3101 | which is a list of the parameters to be prompted for before a | |
3102 | connection is established. | |
041d709f CY |
3103 | |
3104 | *** The command `sql-product-interactive' now takes a prefix argument, | |
34e8a2da | 3105 | which causes it to prompt for an SQL product. |
041d709f | 3106 | |
34e8a2da | 3107 | *** Product-specific SQL interactive commands now take prefix arguments. |
041d709f CY |
3108 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), |
3109 | given a prefix argument, prompt for a name for the SQL interactive | |
3110 | buffer. This reduces the need for calling `sql-rename-buffer'. | |
3111 | ||
3112 | *** SQL interactive modes suppress command continuation prompts, and | |
3113 | replace tabs with spaces. The first change impacts multiple line SQL | |
3114 | statements entered with C-j between each line, statements yanked into | |
3115 | the buffer and statements sent with `sql-send-*' functions. The | |
34e8a2da GM |
3116 | second prevents the MySQL and Postgres interpreters from listing |
3117 | object name completions when sent text via `sql-send-*' functions. | |
041d709f CY |
3118 | |
3119 | *** New command `sql-connect' starts a predefined SQLi session, | |
3120 | using the login parameters from `sql-connection-alist'. | |
3121 | ||
3122 | *** New "Save Connection" menu item in SQLi buffers. | |
3123 | This gathers the login params specified for the SQLi session, if it | |
3124 | was not started by a connection, and saves them as a new connection. | |
3125 | ||
34e8a2da GM |
3126 | *** New commands for listing database objects and details: |
3127 | sql-list-all and sql-list-table. | |
041d709f CY |
3128 | |
3129 | *** An API for manipulating SQL product definitions has been added. | |
3130 | ||
3131 | ** TeX modes | |
3132 | ||
3133 | *** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. | |
412b9ee5 | 3134 | |
459bba37 | 3135 | ** Tramp |
dfdb4cad | 3136 | |
7d301ae6 | 3137 | *** New inline access method "ksu" (kerberized su). |
dfdb4cad | 3138 | |
459bba37 | 3139 | *** The following access methods are discontinued: "ssh1_old", |
ea843702 | 3140 | "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish". |
dfdb4cad | 3141 | |
b011fbfe GM |
3142 | *** The user option `remote-file-name-inhibit-cache' controls whether |
3143 | remote file attributes are cached for better performance. | |
dfdb4cad | 3144 | |
58f74fe4 MA |
3145 | *** The option `ange-ftp-binary-file-name-regexp' has changed its |
3146 | default value to "". | |
dfdb4cad | 3147 | |
7d301ae6 CY |
3148 | *** Handlers for `file-selinux-context' and `set-file-selinux-context' |
3149 | for remote machines which support SELinux. | |
58f74fe4 | 3150 | |
dfdb4cad | 3151 | ** New function `url-queue-retrieve', which behaves like url-retrieve, |
a48ec60c GM |
3152 | but with limits (`url-queue-parallel-processes', `url-queue-timeout') on |
3153 | the degree of parallelism. | |
177549d0 | 3154 | |
0c32ce32 CY |
3155 | ** VC and related modes |
3156 | ||
3157 | *** Support for pulling on distributed version control systems. | |
7d301ae6 CY |
3158 | The command C-x v + (`vc-pull') runs a "pull" operation, if it is |
3159 | supported (currently with Bzr, Git, and Mercurial), to update the | |
3160 | current branch and working tree. A prefix argument means to prompt | |
3161 | the user for specifics, e.g. a pull location. | |
0c32ce32 | 3162 | |
dab3703d | 3163 | *** `vc-update' is now an alias for `vc-pull'. |
0c32ce32 CY |
3164 | |
3165 | *** Support for merging on distributed version control systems. | |
7d301ae6 CY |
3166 | The command C-x v m (`vc-merge') now runs a "merge" operation, if it |
3167 | is supported (currently with Bzr, Git, and Mercurial), to merge | |
3168 | changes from another branch into the current one. It prompts for | |
3169 | specifics, e.g. a merge source. | |
0c32ce32 | 3170 | |
2afef60a | 3171 | *** New option `vc-revert-show-diff' controls whether `vc-revert' |
bbe43420 | 3172 | shows a diff while querying the user. It defaults to t. |
2afef60a | 3173 | |
d4eb88c7 CY |
3174 | *** Log entries in some Log View buffers can be toggled to display a |
3175 | longer description by typing RET (log-view-toggle-entry-display). | |
dab3703d GM |
3176 | This is currently supported for Bzr, Git, and Mercurial (to support |
3177 | another backend, define a `log-view-expanded-log-entry-function'). | |
7d301ae6 | 3178 | In the Log View buffers made by C-x v L (`vc-print-root-log'), you can |
d4eb88c7 CY |
3179 | use this to display the full log entry for the revision at point. |
3180 | ||
1c6c854e CS |
3181 | *** New command `vc-ediff' allows visual comparison of two revisions |
3182 | of a file similar to `vc-diff', but using ediff backend. | |
3183 | ||
86c60681 CY |
3184 | *** The option `vc-initial-comment' was removed in Emacs 23.2, but |
3185 | this was not advertised at the time. | |
3186 | ||
86c60681 CY |
3187 | *** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'. |
3188 | Since Emacs 23, it has done the same thing as `toggle-read-only', but | |
80c6d77f GM |
3189 | this was not advertised at the time. |
3190 | ||
041d709f CY |
3191 | ** Obsolete modes |
3192 | ||
23d70505 GM |
3193 | *** abbrevlist.el |

f8ca9162 | 3195 | *** erc-hecomplete.el (use erc-pcomplete.el instead) |
23d70505 GM |
3196 | |
3197 | *** partial-completion-mode (complete.el) is obsolete. | |
041d709f CY |
3198 | You can get a comparable behavior with: |

3200 | (setq completion-pcm-complete-word-inserts-delimiters t) | |
3201 | ||
23d70505 GM |
3202 | *** pc-mode.el is obsolete (CUA mode is much more comprehensive). |

2c719188 | 3204 | *** pgg is obsolete (use EasyPG instead). |
041d709f CY |

3206 | *** sregex.el is obsolete, since rx.el is a strict superset. | |
3207 | ||
23d70505 GM |

3214 | ||
05f77e38 | 3215 | *** The Landmark game is now invoked with `landmark', not `lm'. |
c6ad2a4e | 3216 | Its functions and variables have been similarly renamed. |
05f77e38 | 3217 | |

3273 | * Incompatible Lisp Changes in Emacs 24.1 | |
6dfcbe31 | 3274 | |
7d301ae6 CY |
3275 | ** Passing a nil argument to a minor mode function call now ENABLES |
3276 | the minor mode unconditionally. This is so that you can write e.g. | |
3277 | ||
dfdb4cad | 3278 | (add-hook 'text-mode-hook 'foo-mode) |
7d301ae6 | 3279 | |
dfdb4cad CY |
3280 | to enable foo-mode in Text mode buffers, removing the need for |
3281 | `turn-on-foo-mode' style functions. This affects all mode commands | |
3282 | defined by `define-minor-mode'. If called interactively, the mode | |
3283 | command still toggles the minor mode. | |
7d301ae6 | 3284 | |
d268b4fe CY |
3285 | ** The return value of `backup-buffer' has changed. |
3286 | It is now a list of three elements, where the second element is a list | |
3287 | describing the original file's SELinux context. If Emacs or the | |
f003f294 | 3288 | system lacks SELinux support, the context list is (nil nil nil nil). |
7d301ae6 | 3289 | See "Basic SELinux support" above, under "Changes in Emacs 24.1". |
d268b4fe | 3290 | |
dfdb4cad CY |
3291 | ** `char-direction-table' and the `char-direction' function were deleted. |
3292 | They were buggy and inferior to the new support of bidirectional | |
3293 | editing introduced in Emacs 24. If you need the bidirectional | |
3294 | properties of a character, use `get-char-code-property' with the last | |
3295 | argument `bidi-class'. | |
fa6996bc | 3296 | |
470d996d TV |
3297 | ** `copy-directory' now copies the source directory as a subdirectory |
3298 | of the target directory, if the latter is an existing directory. The | |
3299 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy | |
3300 | the contents directly into a pre-existing target directory. | |
3301 | ||
9173a8fb CY |
3302 | ** For mouse click input events in the text area, the Y pixel |
3303 | coordinate in the POSITION list now counts from the top of the text | |
3304 | area, excluding any header line. Previously, it counted from the top | |
3305 | of the header line. | |
3306 | ||
7d301ae6 CY |
3307 | ** Support for "old-style" backquotes, obsolete for 10+ years, has |
3308 | been further reduced. Now a backquote not followed by a space is | |
3309 | always treated as a "new-style" backquote. Please remove all | |
3310 | "old-style" backquotes from your code. If your code uses backquotes | |
3311 | as documented in the Elisp manual, and compiles without warning, then | |
3312 | you have nothing to do in this regard. Code not following the | |
3313 | appropriate conventions may fail to compile. | |
50ab02c5 CY |
3314 | |
3315 | The most common cause of trouble seems to be an old-style backquote | |
3316 | followed by a newline. Another cause of trouble is vector notation | |
3317 | for key sequence notation: instead of [(control ,)] and [(control ')], | |
3318 | you should write [(control ?,)] and [(control ?')], which will work in | |
7d301ae6 | 3319 | older Emacsen too. |

3323 | replaced all known uses. | |
3324 | ||
7d301ae6 CY |
3325 | ** `view-buffer' now treats special mode-class in the same way that |
3326 | `view-file' has since Emacs 22 (i.e. it won't enable View mode if the | |
3327 | major mode is special). | |

0a19a6f8 JB |
3332 | and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'. |
3333 | With these alist entries omitted, `make-frame' checks the value of the | |
3334 | variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create | |
3335 | a menu-bar or tool-bar, respectively. If the alist entries are added, | |
3336 | they override the value of `menu-bar-mode'/`tool-bar-mode'. | |
6431f2e6 | 3337 | |
7d301ae6 CY |
3338 | *** The menu bar bindings's caches are not used any more. |
3339 | Use (where-is-internal <def> nil t) instead. | |

fe0aa820 | 3341 | ** Regions created by mouse dragging are now normal active regions, |
dfdb4cad | 3342 | similar to those created by shift-selection (see Selection changes |

041d709f | 3402 | ** Code can now use lexical scoping by default instead of dynamic scoping. |
dfdb4cad | 3403 | The `lexical-binding' variable enables lexical scoping for local |
48da7392 | 3404 | variables. It is typically set via a file-local variable in the first |
dfdb4cad CY |
3405 | line of the file, in which case it applies to all the code in that |
3406 | file. | |
3407 | ||
041d709f CY |

3409 | binding instead of the old dynamic binding mode. | |
dfdb4cad | 3410 | |
041d709f CY |
3411 | *** Lexically scoped interpreted functions are represented with a new form |
3412 | of function value which looks like (closure ENV ARGS &rest BODY). | |
3413 | ||
3414 | *** New macro `letrec' to define recursive local functions. | |
dfdb4cad CY |
3415 | |
3416 | *** `defvar' and `defconst' now mark the variable as special (dynamic). | |
3417 | So do `defcustom' and other forms that call `defvar' as a subroutine. | |
3418 | ||
041d709f CY |

3428 | ** Changes for bidirectional display and editing | |
f1816485 | 3429 | |
041d709f | 3430 | *** New function `current-bidi-paragraph-direction'. |
7d301ae6 | 3431 | This returns the base direction of the paragraph at point. |
041d709f | 3432 | |
041d709f | 3433 | *** New function `bidi-string-mark-left-to-right'. |
dfdb4cad CY |
3434 | Given a string containing characters from right-to-left scripts, this |
3435 | function returns another string which can be safely inserted into a | |
3436 | buffer, such that any following text will be always displayed to the | |
7d301ae6 CY |
3437 | right of that string. (This works by appending an invisible Unicode |
3438 | "LEFT-TO-RIGHT MARK" character if the argument string might need it.) | |
041d709f | 3439 | |
7d301ae6 | 3440 | This is useful when the buffer has overall left-to-right paragraph |
dfdb4cad CY |
3441 | direction and you need to insert a string whose contents are not known |
3442 | in advance, without disrupting the layout of the line. | |

3446 | *** Window tree functions are accessible in Elisp. |
3447 | Functions are provided to return the parent, siblings or child windows | |
3448 | of any window including internal windows (windows not associated with a | |
3449 | buffer) in the window tree. | |
dfdb4cad | 3450 | |
24300f5f CY |
3451 | **** New function `window-valid-p' gives non-nil for live and internal |
3452 | windows. | |
dfdb4cad | 3453 | |
24300f5f | 3454 | **** Window manipulation can deal with internal windows. |
c4682d18 MR |
3455 | Many window handling functions like `split-window', `delete-window', or |
3456 | `delete-other-windows' as well as the window resizing functions can now | |
3457 | act on any window including internal ones. | |
dfdb4cad | 3458 | |
c4682d18 MR |
3459 | *** window-total-height/-width vs window-body-height/-width. |
3460 | The function `window-height' has been renamed to `window-total-height' | |
3461 | and `window-width' has been renamed to `window-body-width'. The old | |
3462 | names are provided as aliases. Two new functions `window-total-width' | |
3463 | and `window-body-height' are provided. | |
dfdb4cad | 3464 | |
c4682d18 MR |
3465 | *** Window parameters specific to window handling functions. |
3466 | For each window you can specify a parameter to override the default | |
3467 | behavior of a number of functions like `split-window', `delete-window' | |
ed6235ea MR |
3468 | and `delete-other-windows'. The variable `ignore-window-parameters' |
3469 | allows to ignore processing such parameters. | |
dfdb4cad | 3470 | |
c4682d18 | 3471 | *** New semantics of third argument of `split-window'. |
c4682d18 MR |
3472 | The third argument of `split-window' has been renamed to SIDE and can be |
3473 | set to any of the values 'below, 'right, 'above, or 'left to make the | |
3474 | new window appear on the corresponding side of the window that shall be | |
3475 | split. Any other value of SIDE will cause `split-window' to split the | |
3476 | window into two side-by-side windows as before. | |
dfdb4cad | 3477 | |
c4682d18 | 3478 | *** Window resizing functions. |
487ffd7a | 3479 | A new standard function for resizing windows called `window-resize' has |
c4682d18 MR |
3480 | been introduced. This and all other functions for resizing windows no |
3481 | longer delete any windows when they become too small. | |
dfdb4cad | 3482 | |
b3c0dbfd MR |
3483 | *** Deleting the selected window now selects the most recently selected |
3484 | live window on that frame instead. | |
dfdb4cad | 3485 | |
c4682d18 MR |
3486 | *** `adjust-window-trailing-edge' adjustments. |
3487 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | |
3488 | is able to resize other windows if a window adjacent to the trailing | |
3489 | edge cannot be shrunk any more. This makes its behavior more similar to | |
3490 | that of Emacs 21 without compromising, however, its inability to delete | |
3491 | windows which was introduced in Emacs 22. | |
dfdb4cad | 3492 | |
c4682d18 MR |
3493 | *** Window-local buffer lists. |
3494 | Windows now have local buffer lists. This means that removing a buffer | |
3495 | from display in a window will preferably show the buffer previously | |
3496 | shown in that window with its previous window-start and window-point | |
3497 | positions. This also means that the same buffer may be automatically | |
3498 | shown twice even if it already appears in another window. | |
dfdb4cad | 3499 | |
bee0fcef CY |
3500 | *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW, |
3501 | which if non-nil requires the buffer to be displayed in the currently | |
3502 | selected window, signaling an error otherwise. If nil, another window | |
3503 | can be used, e.g. if the selected one is strongly dedicated. | |
dfdb4cad | 3504 | |
0a2132ba | 3505 | *** `split-window-vertically' and `split-window-horizontally' renamed |
2d197ffb CY |
3506 | to `split-window-below' and `split-window-right' respectively. |
3507 | The old names are kept as aliases. | |
dfdb4cad | 3508 | |
0a2132ba CY |
3509 | *** Display actions |
3510 | ||
3511 | **** The second arg to `display-buffer' and `pop-to-buffer' is now | |
3512 | named ACTION, and takes a display action of the same form as | |
3513 | `display-buffer-base-action' (see Changes, above). A non-nil, | |
3514 | non-list value is treated specially, as the old meaning. | |
3515 | ||
3516 | **** New variable `display-buffer-overriding-action'. | |
3517 | ||
3518 | **** The procedure of `display-buffer' etc. to choose a window is | |
3519 | determined by combining `display-buffer-overriding-action', | |
3520 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', | |
3521 | and `display-buffer-fallback-action'. The second and fourth of these | |
3522 | are user-customizable variables. | |
3523 | ||
3524 | See the docstring of `display-buffer' for details. | |
bee0fcef | 3525 | |
20d2304d CY |
3526 | *** New functions `window-state-get' and `window-state-put'. |
3527 | These functions allow to save and restore the state of an arbitrary | |
3528 | frame or window as an Elisp object. | |

3533 | properties of the current completion: | |
a2a25d24 SM |
3534 | - :annotate-function, same as the old completion-annotate-function. |
3535 | - :exit-function, function to call after completion took place. | |

a2a25d24 | 3541 | |
620c53a6 SM |
3542 | *** New `metadata' method for completion tables. The metadata thus returned |
3543 | can specify various details of the data returned by `all-completions': | |
3544 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | |
3545 | used to select a style in completion-category-overrides. | |
3546 | - `annotation-function' to add annotations in *Completions*. | |
3547 | - `display-sort-function' to specify how to sort entries in *Completions*. | |

3558 | text terminal display, via a char-table entry that is a cons cell. |
3559 | ||
7d301ae6 | 3560 | ** `pre-command-hook'/`post-command-hook' are not reset to nil on error. |
f6d62986 SM |
3561 | Instead, the offending function is removed. |
3562 | ||
b1f6fa26 CY |
3563 | ** New hook types |
3564 | ||
3565 | *** New function `run-hook-wrapped' for running an abnormal hook by | |
3566 | passing the hook functions as arguments to a "wrapping" function. | |
e7bc51d0 | 3567 | Like `run-hook-with-args-until-success', it stops at the first |
5385447f | 3568 | non-nil return value. |
e7bc51d0 | 3569 | |
b1f6fa26 CY |
3570 | *** New macro `with-wrapper-hook' for running an abnormal hook as a |
3571 | set of "wrapping" filters, similar to around advice. | |
54521c99 GM |
3572 | (A version of this macro was actually added in Emacs 23.2 but was not |
3573 | advertised at the time.) | |
f6d62986 | 3574 | |
0b19b281 | 3575 | ** Debugger changes |
dfdb4cad | 3576 | |
0b19b281 | 3577 | *** New macro `condition-case-unless-debug' (this was actually added in |
1be3ca5a | 3578 | Emacs 23.1 as condition-case-no-debug, but not advertised) |
dfdb4cad | 3579 | |
0b19b281 | 3580 | *** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised. |
dfdb4cad | 3581 | |
0b19b281 | 3582 | *** Variable `stack-trace-on-error' removed. |
dfdb4cad | 3583 | |
0b19b281 CY |
3584 | *** The debugger can now "continue" from an error, which means it will |
3585 | jump to the error handler as if the debugger had not been invoked | |
3586 | instead of jumping all the way to the top-level. | |
dfdb4cad | 3587 | |
0b19b281 CY |
3588 | *** Set `debug-on-event' to enter the debugger on events like SIGUSR1. |
3589 | This can be useful when `inhibit-quit' is set. | |
d6b1d521 | 3590 | |
953cebf5 | 3591 | ** The new function `server-eval-at' allows evaluation of Lisp forms on |
37576acd | 3592 | named Emacs server instances. |
7deebf1b | 3593 | |
1b9f60cc GM |
3594 | ** `call-process' and `call-process-region' allow a `(:file "file")' spec |
3595 | to redirect STDOUT to a file. | |
7deebf1b | 3596 | |
7d301ae6 CY |
3597 | ** The function `format-time-string' now supports the %N directive, |
3598 | for higher-resolution time stamps. | |
da97a9e6 | 3599 | |
0b19b281 | 3600 | ** New input reading functions |
dfdb4cad | 3601 | |
0b19b281 CY |
3602 | *** New function `read-char-choice' reads a restricted set of |
3603 | characters, discarding any inputs not inside the set. | |
dfdb4cad | 3604 | |
0b19b281 CY |
3605 | *** The command `read-color' now requires a match for a color name |
3606 | or RGB triplet, instead of signaling an error if the user provides | |
3607 | invalid input. | |
dfdb4cad | 3608 | |
0b19b281 | 3609 | **** `facemenu-read-color' is now an alias for `read-color'. |
3ef01959 | 3610 | |
2e288d54 JB |
3611 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
3612 | The variable is now used to load all kind of supported dynamic libraries, | |
3613 | not just image libraries. The previous name is still available as an | |
3614 | obsolete alias. | |
3615 | ||
0b19b281 | 3616 | ** Syntax parsing changes |
dfdb4cad | 3617 | |
0b19b281 | 3618 | *** New variable `syntax-propertize-function'. |
04e2ce72 | 3619 | This replaces `font-lock-syntactic-keywords' which is now obsolete. |
cf38dd42 SM |
3620 | This allows syntax-table properties to be set independently from font-lock: |
3621 | just call syntax-propertize to make sure the text is propertized. | |
3622 | Together with this new variable come a new hook | |
3623 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
3624 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
3625 | as-is; and syntax-propertize-rules which provides a new way to specify | |
3626 | syntactic rules. | |
dfdb4cad | 3627 | |
0b19b281 | 3628 | *** Syntax tables support a new "comment style c" additionally to style b. |
a2e5caf7 | 3629 | |
7d301ae6 | 3630 | ** New hook `post-self-insert-hook', run after `self-insert-command'. |
041d709f | 3631 | |
4e2db1fe | 3632 | ** frame-local variables cannot be let-bound any more. |
041d709f | 3633 | |
15de15c6 | 3634 | ** Major and minor mode changes |
dfdb4cad | 3635 | |
0b19b281 CY |
3636 | *** `set-auto-mode' now respects mode: local variables at the end of files, |
3637 | as well as those in the -*- line. | |
dfdb4cad | 3638 | |
15de15c6 CY |
3639 | *** `prog-mode' is a new major mode from which programming modes |
3640 | should be derived. | |
dfdb4cad | 3641 | |
15de15c6 CY |
3642 | **** `prog-mode-hook' can be used to enable features for programming |
3643 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable | |
3644 | on-the-fly spell checking for comments and strings. | |
dfdb4cad | 3645 | |
15de15c6 CY |
3646 | *** New hook `change-major-mode-after-body-hook', run by |
3647 | `run-mode-hooks' just before any other mode hooks. | |
dfdb4cad | 3648 | |
7a9a2fc6 GM |
3649 | *** Enabled globalized minor modes can be disabled in specific major modes. |
3650 | If the global mode is global-FOO-mode, then run (FOO-mode -1) in the | |
3651 | major mode's hook, where FOO-mode toggles the mode on a per-buffer basis. | |
dfdb4cad | 3652 | |
feb8a83a | 3653 | *** `define-minor-mode' accepts new keywords :variable, :after-hook. |
f44379e7 | 3654 | |
7d301ae6 CY |
3655 | ** File-handling changes |
3656 | ||
7d301ae6 | 3657 | *** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
3658 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
3659 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
3660 | argument is supplied (see Trash changes, above). | |
53967e09 | 3661 | |
7d301ae6 | 3662 | *** New file predicates: `file-equal-p', `file-in-directory-p'. |
ec70a47d | 3663 | |
4039c786 CY |
3664 | ** Tool-bars can display separators. |
3665 | Tool-bar separators are handled like menu separators in menu-bar maps, | |
94975270 | 3666 | i.e. via menu entries of the form `(menu-item "--")'. |
9317e499 | 3667 | |
00fe2df1 JL |
3668 | ** Image API |
3669 | ||
18af70d0 CY |
3670 | *** Animated images support (currently animated gifs only). |
3671 | ||
3672 | **** `image-animated-p' returns non-nil if an image can be animated. | |
3673 | ||
3674 | **** `image-animate' animates a supplied image spec. | |
3675 | ||
3676 | **** `image-animate-timer' returns the timer object for an image that | |
3677 | is being animated. | |
00fe2df1 | 3678 | |
7cb76fe0 GM |
3679 | *** `image-extension-data' has been renamed to `image-metadata'. |
3680 | The old name is an obsolete alias to the new one. | |
1546c559 | 3681 | |
b4ac6e8c GM |
3682 | *** Image mode can view any image type that ImageMagick supports. |
3683 | This requires Emacs to be built with ImageMagick support. | |
7d301ae6 CY |
3684 | |
3685 | **** New function `imagemagick-types', defined if ImageMagick support | |
3686 | is enabled, returns a list of image file extensions that your | |
3687 | ImageMagick installation supports. | |
3688 | ||
3689 | **** New function `imagemagick-register-types' enables ImageMagick | |
3690 | image types in Image mode and in `create-image' and other helper | |
3691 | functions. | |
3692 | ||
3693 | **** New option `imagemagick-types-inhibit' excludes certain | |
3694 | ImageMagick image types from `imagemagick-register-types'. | |
3695 | ||
7d301ae6 CY |
3696 | **** With ImageMagick support, there are extra Image mode commands to |
3697 | resize and rotate images: `image-transform-fit-to-height', | |
3698 | `image-transform-fit-to-width', `image-transform-set-rotation', and | |
3699 | `image-transform-set-scale'. | |
041d709f | 3700 | |
7d301ae6 CY |
3701 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
3702 | passes it to the mail user agent function. This argument specifies an | |
3703 | action for returning to the caller after finishing with the mail. For | |
3704 | example, this is used by Rmail to optionally delete a mail window. | |
b4ac6e8c | 3705 | |
71c17aec | 3706 | ** XML and HTML parsing |
483ab230 CY |
3707 | If Emacs is compiled with libxml2 support, there are two new |
3708 | functions: `libxml-parse-html-region' (which parses "real world" HTML) | |
3709 | and `libxml-parse-xml-region' (which parses XML). Both return an | |
3710 | Emacs Lisp parse tree. | |
4b9832a6 | 3711 | |
7d301ae6 | 3712 | ** Networking and encryption changes |
e2574f2c | 3713 | |
7d301ae6 CY |
3714 | *** `open-network-stream' can now be used to open an encrypted stream. |
3715 | It now accepts an optional `:type' parameter for initiating a TLS | |
3716 | connection, directly or via STARTTLS. To do STARTTLS, additional | |
3717 | parameters (`:end-of-command', `:success', `:capabilities-command') | |
3718 | must also be supplied. | |
3719 | ||
3720 | *** New library gnutls.el. | |
dfdb4cad CY |
3721 | The new function `gnutls-available-p' returns non-nil if Emacs is |
3722 | built with GnuTLS support. The main entry points are | |
3723 | `open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use | |
3724 | these functions through `open-network-stream', because that can | |
7d301ae6 CY |
3725 | upgrade connections through STARTTLS opportunistically or use plain |
3726 | SSL, depending on your needs. For debugging, set `gnutls-log-level' | |
3727 | greater than 0. | |
3728 | ||
7d301ae6 CY |
3729 | *** New primitive `secure-hash' that supports many secure hash algorithms: |
3730 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library | |
3731 | sha1.el has been removed. The `sha1' feature is provided by default. | |
71c17aec | 3732 | |
a6020335 MH |
3733 | ** Isearch |
3734 | ||
3735 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | |
3736 | ||
9326ba26 CY |
3737 | ** Progress reporters can now "spin". |
3738 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
3739 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
3740 | time you call `progress-reporter-update' on that progress reporter, | |
3741 | with a nil or omitted VALUE argument, the reporter message is | |
3742 | displayed with a "spinning bar". | |
3743 | ||
3e214b50 JB |
3744 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is |
3745 | being reverted, even if the buffer has a local `revert-buffer-function'. | |
3746 | ||
001bf877 GM |
3747 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. |
3748 | If delayed-warnings-list is non-nil, the command loop calls | |
7d301ae6 CY |
3749 | `delayed-warnings-hook' after `post-command-hook'. At present, this |
3750 | is only used by Emacs on some platforms to display warnings during | |
3751 | startup, which might otherwise not be noticed. This uses the | |
3752 | functions `display-delayed-warnings' and `collapse-delayed-warnings'. | |
001bf877 | 3753 | |
6420d28b CY |
3754 | ** rx.el has a new `group-n' construct for explicitly numbered groups. |
3755 | ||
dac86404 GM |
3756 | ** New function `make-composed-keymap' that constructs a new keymap |
3757 | from multiple input maps. You can use this to make a keymap that | |
3758 | inherits from multiple maps, eg: | |
3759 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) | |
43dc9f5b | 3760 | |
c8f6ec5c GM |
3761 | ** New function `string-prefix-p'. |
3762 | (This was actually added in Emacs 23.2 but was not advertised at the time.) | |
3763 | ||
27f7ef2f | 3764 | ** New reader macro ## that stands for the empty symbol. |
43dc9f5b AS |
3765 | This means that the empty symbol can now be read back. Also, #: by itself |
3766 | (when not immediately followed by a possible symbol character) stands for | |
3767 | an empty uninterned symbol. | |
041d709f | 3768 | |
fead402d CY |
3769 | ** New math functions `isnan', `copysign', `frexp', `ldexp'. |
3770 | ||
7d301ae6 | 3771 | ** The following functions and variables are obsolete: |
041d709f | 3772 | |
05f77e38 GM |
3773 | *** `tooltip-use-echo-area' is obsolete. |
3774 | Rather than setting this to t, disable Tooltip mode instead. | |
3775 | ||
041d709f CY |
3776 | *** buffer-substring-filters is obsolete. |
3777 | Use `filter-buffer-substring-functions' instead. | |
3778 | ||
3779 | *** `byte-compile-disable-print-circle' is obsolete. | |
3780 | ||
3781 | *** `deferred-action-list' and `deferred-action-function' are obsolete. | |
f160676e GM |
3782 | Use `post-command-hook' instead. |
3783 | ||
67e729a5 CY |
3784 | *** `font-lock-maximum-size' is obsolete. |
3785 | ||
eb199145 | 3786 | \f |
93e0bed6 | 3787 | * Changes in Emacs 24.1 on Non-Free Operating Systems |
d53a60a6 | 3788 | |
7a22e700 | 3789 | ** On MS Windows, Emacs warns when using the obsolete init file _emacs, |
a2f0118c GM |
3790 | and also when HOME is set to C:\ by default. |
3791 | ||
7a22e700 | 3792 | ** New configure.bat options |
04779484 | 3793 | |
7a22e700 | 3794 | *** --enable-checking builds Emacs with extra runtime checks. |
e3aef5c6 | 3795 | |
7a22e700 | 3796 | *** --distfiles specifies files to be included in binary distribution. |
e2574f2c | 3797 | |
7a22e700 OK |
3798 | *** --without-gnutls disables automatic GnuTLS detection. |
3799 | ||
a0d363f4 | 3800 | *** --lib for general library linkage, works with the USER_LIBS build variable. |
e2574f2c | 3801 | |
0a19a6f8 | 3802 | ** New make target `dist' to create binary distribution for MS Windows. |
e3aef5c6 | 3803 | |
1f5e1a16 GM |
3804 | ** The Lisp function `w32-default-color-map' is now obsolete. |
3805 | (It is only used internally in the Emacs C code.) | |
5430d399 | 3806 | |
1f5e1a16 GM |
3807 | ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but |
3808 | reappear on mouse-over. (Requires OS X 10.6 or later.) | |
04e2ce72 | 3809 | |
ad7c802c CY |
3810 | ** On Mac OS X, dragging a file into Emacs visits the file, like on |
3811 | other platforms, rather than inserting its contents into the buffer. | |
