780d7bb9 RS |
41 | ** Emacs now supports using both X displays and ttys in one session. |
42 | You can also use any number of different ttys. | |
43 | ||
44 | You can test for the presence of this feature in your Lisp code by | |
45 | testing for the `multi-tty' feature. | |
46 | ||
251ad2de TTN |
47 | ** Emacs comes with a new set of icons for Mac OS X. |
48 | OS-X-style icons (an application icon and a relevant document icon) | |
49 | were contributed by Kentaro Ohkouchi. | |
50 | Source files for these icons can be found in Emacs.app/Contents/Resources. | |
51 | ||
f664fee9 MC |
52 | ** Built-in functions (subr) can now have an interactive specification |
53 | that is not a prompt string. If the `intspec' parameter of a `DEFUN' | |
54 | starts with a `(', the string is evaluated as a Lisp form. | |
55 | ||
56 | ** set-file-modes is now interactive and can take the mode value in | |
57 | symbolic notation thanks to auxiliary functions. | |
58 | ||
90ab5c62 SM |
59 | ** split-window-preferred-function specifies whether display-buffer should |
60 | split windows vertically or horizontally. | |
61 | ||
24cdde13 GM |
62 | ** Emacsclient has been extended to support opening a new terminal |
63 | frame. Its behavior has been changed to open a new Emacs frame by | |
64 | default. Use the -c option to get the old behavior of opening files in | |
65 | the currently selected Emacs frame. | |
66 | ||
c0dadae9 MC |
67 | ** The refcards are now shipped as PDF files. |
68 | ||
795a2a94 GM |
69 | ** Emacs now supports the SVG image format through librsvg2. |
70 | ||
75f6af19 | 71 | ** If you set find-file-confirm-nonexistent-file to t, then C-x C-f |
0a963185 SM |
72 | requires confirmation before opening a non-existent file. |
73 | ||
6dadd99f NR |
74 | ** If the gpm mouse server is running and t-mouse-mode enabled, Emacs uses a |
75 | Unix socket in a GNU/Linux console to talk to server, rather than faking events | |
76 | using the client program mev. This C level approach provides mouse | |
77 | highlighting, and help echoing in the minibuffer. | |
78 | ||
c2e8590b TTN |
79 | ** The new variable next-error-recenter specifies how next-error should |
80 | recenter the visited source file. Its value can be a number (for example, | |
81 | 0 for top line, -1 for bottom line), or nil for no recentering. | |
82 | ||
d87b5ced | 83 | ** The mode-line displays a `@' if the default-directory for the current buffer |
1f2e1c75 | 84 | is on a remote machine, or a hyphen otherwise. |
6c5d503f | 85 | |
c9447ae1 GM |
86 | ** The mode-line displays a mode menu when mouse-1 is clicked on a minor mode, |
87 | in the same way as it already did for major modes. | |
88 | ||
de3054d5 | 89 | ** The new command balance-windows-area balances windows both vertically |
62e3c31f | 90 | and horizontally. |
d466e9fc SM |
91 | |
92 | ** The new command close-display-connection can be used to close a connection | |
93 | to a remote display, e.g. because the display is about to become unreachable. | |
6c5d503f MA |
94 | |
95 | ** The command shell prompts for the default directory, when it is | |
96 | called with a prefix, and the default directory is a remote file name. | |
de3054d5 | 97 | This is because some file name handlers (like ange-ftp) are not able to |
6c5d503f | 98 | run processes remotely. |
aff2ba04 RS |
99 | |
100 | ** The new command `display-time-world' starts an updating time display | |
101 | using several time zones, in a buffer. | |
6dadd99f | 102 | \f |
0bfd685e | 103 | * Startup Changes in Emacs 23.1 |
21f7b9d8 | 104 | |
56e1896b JL |
105 | ** New user option `initial-buffer-choice' specifies what to display |
106 | after starting Emacs: startup screen, *scratch* buffer, visiting a | |
107 | file or directory. | |
108 | ||
aa5310e4 DK |
109 | ** New alias `argv' for `command-line-args-left' |
110 | This is a convenience alias, so that one can write `(pop argv)' | |
111 | inside of --eval command line arguments in order to access | |
112 | following arguments. | |
f8fd7ed3 GM |
113 | |
114 | ** The abbrev file is no longer read at startup in batch mode. | |

122 | ** M-q now fills the region if the region is active and | |
123 | `transient-mark-mode' is turned on. Otherwise, it fills the current | |
ecde850a | 124 | paragraph. |
1ac03a31 | 125 | |

dc868f13 JL |
127 | ** M-$ now checks spelling of the region if the region is active and |
128 | `transient-mark-mode' is turned on. Otherwise, it checks spelling of the | |
129 | word at point. | |
130 | ||
6dd697d9 DN |
131 | ** TAB now indents the region if the region is active and |
132 | `transient-mark-mode' is turned on. | |
133 | ||
24cdde13 GM |
134 | ** C-z now invokes `suspend-frame', C-x C-c now invokes |
135 | `save-buffers-kill-terminal'. | |
136 | ||
a151f82c SS |
137 | ** New command kill-matching-buffers kills buffers whose name matches a regexp. |
138 | ||
539f5bda GM |
139 | ** `interprogram-paste-function' can now return one string or a list |
140 | of strings. In the latter case, Emacs puts the second and following | |
141 | strings on the kill ring. | |
142 | ||
297b8ccd JL |
143 | ** Minibuffer changes: |
144 | ||
145 | *** isearch started in the minibuffer searches in the minibuffer history. | |
146 | Reverse isearch commands (C-r, C-M-r) search in previous minibuffer | |
147 | history elements, and forward isearch commands (C-s, C-M-s) search in | |
148 | next history elements. When the reverse search reaches the first history | |
149 | element, it wraps to the last history element, and the forward search | |
150 | wraps to the first history element. When the search is terminated, the | |
151 | history element containing the search string becomes the current. | |

154 | * New Modes and Packages in Emacs 23.1 | |
0091c67e | 155 | |
1816bda7 MC |
156 | ** The package doc-view.el has been added. It supports viewing of PDF, |
157 | PostScript and DVI documents inside an Emacs buffer by converting the | |
158 | document to a set of PNG images first. One can also search for a | |
159 | regular expression in the document. The commentary of the file explains | |
160 | its usage. | |
161 | ||
ddc961c5 | 162 | ** A new game called `bubbles' has been added. |
a0818148 | 163 | |
dcd6e8d7 | 164 | ** minibuffer-indicate-depth-mode shows the minibuffer depth in the prompt. |
3f7194ed | 165 | |
15f3eb73 MO |
166 | ** Remember Mode (remember.el) is now included with Emacs. It is a |
167 | mode for quickly jotting down things to remember. Included with | |
168 | remember.el is a backend that can save notes to a Diary file. Please | |
169 | consult the Remember Manual for usage details. | |

172 | * Changes in Specialized Modes and Packages in Emacs 23.1 | |
61d244ca | 173 | |
e047f448 SM |
174 | ** abbrev was rewritten in Elisp and extended with more flexibility. |
175 | *** New functions: abbrev-get, abbrev-put, abbrev-table-get, abbrev-table-put, | |
176 | abbrev-table-p. | |
177 | *** Special hook `abbrev-expand-functions' obsoletes `pre-abbrev-expand-hook'. | |
178 | *** `make-abbrev-table', `define-abbrev', `define-abbrev-table' all take | |
179 | extra arguments for arbitrary properties. | |
180 | *** New variable `abbrev-minor-mode-table-alist'. | |
181 | *** `local-abbrev-table' can hold a list of abbrev-tables. | |
182 | *** Abbrevs have now the following special properties: | |
183 | `count', `system-flag', `:enable-function', `:case-fixed'. | |
184 | *** Abbrev-tables have now the following special properties: | |
185 | `:parents', `:case-fixed', `:enable-function', `:regexp', | |
186 | `abbrev-table-modiff'. | |
187 | ||
12bbb989 JL |
188 | ** isearch can now search through multiple ChangeLog files. |
189 | When running isearch in a ChangeLog file, if the search fails, | |
190 | then another C-s tries searching the previous ChangeLog, | |
191 | if there is one (e.g. go from ChangeLog to ChangeLog.12). | |
192 | ||
9097e8af RS |
193 | This is enabled if isearch-buffers-multi is non-nil. |
194 | ||
b9694062 JL |
195 | +++ |
196 | ** In Dired-x, all command guesses for ! are now added to the default | |
197 | list accessible by M-n instead of pushing all guesses temporarily into | |
198 | the history list. | |
199 | ||
c3bb6fdb SM |
200 | ** smerge-refine highlights word-level details of changes in conflict. |
201 | It's used automatically as you move through conflicts, see smerge-auto-refine. | |
202 | ||
203 | ** diff-refine-hunk highlights word-level details of changes in a diff hunk. | |
204 | It's used automatically as you move through hunks, see diff-auto-refine. | |
205 | ||
e6a01e4e | 206 | ** archive-mode has basic support to browse Rar archives. |
c3bb6fdb | 207 | |
24cdde13 GM |
208 | ** talk.el has been extended for multiple tty support. |
209 | ||
813fb3fe SM |
210 | ** compilation-auto-jump-to-first-error tells `compile' to jump to |
211 | the first error encountered during compilations. | |
212 | ||
b68769f2 | 213 | ** In the `copyright' package, you can specify your copyright holders' names. |
b649d2e4 SM |
214 | Only copyright lines with holders matching copyright-names-regexp will be |
215 | considered for update. | |
216 | ||
e7ce8577 GM |
217 | ** eldoc highlights the function argument under point |
218 | with the face `eldoc-highlight-function-argument'. | |
219 | ||
b68769f2 | 220 | +++ |
8d5cc579 | 221 | ** defcustom accepts new keyword arguments, `:safe' and `:risky', which |
b68769f2 GM |
222 | set a variable's `safe-local-variable' and `risky-local-variable' property. |
223 | ||
56dada42 | 224 | ** VC |
397c4757 DN |
225 | *** Clicking on the VC mode-line entry now pops the VC menu. |
226 | ||
9372a958 | 227 | *** The VC mode-line entry now has a tooltip that explains the VC file status. |
cb223bba | 228 | |
082c5622 DN |
229 | *** VC now supports applying VC operations to a set of files at a time. |
230 | ||
4a11b6b5 ER |
231 | This enables VC to work much more effectively with changeset-oriented |
232 | version-control systems such as Subversion, GNU Arch, Mercurial, and | |
233 | Bzr. VC will now pass a multiple-file commit to these systems | |
234 | as a single changeset. | |
235 | ||
5d503af9 SM |
236 | ** sgml-electric-tag-pair-mode lets you simultaneously edit matched tag pairs. |
237 | ||
332de56f GM |
238 | ** The appearance of superscript and subscript in TeX is more customizable. |
239 | See the documentation of the variables: tex-fontify-script, | |
240 | tex-font-script-display, tex-suscript-height-ratio, and | |
241 | tex-suscript-height-minimum. | |
242 | ||
2793c9bb RW |
243 | ** BibTeX mode: |
244 | ||
245 | *** New `bibtex-entry-format' options `whitespace', `braces', and | |
246 | `string', disabled by default. | |
247 | ||
248 | *** New variable `bibtex-cite-matcher-alist' contains rules to | |
0f3cd6b2 | 249 | identify cited keys in BibTeX entries, used by `bibtex-find-crossref'. |
2793c9bb RW |
250 | |
251 | *** Command `bibtex-url' now allows multiple URLs per entry. | |
252 | ||
cc213f24 MA |
253 | +++ |
254 | ** Tramp | |
255 | ||
256 | *** New connection methods. | |
257 | The new methods "plinkx", "plink2", "psftp", "sftp" and "fish" have | |
258 | been introduced. There are also new so-called gateway methods | |
259 | "tunnel" and "socks". | |
260 | ||
261 | *** Multihop syntax has been removed. | |
262 | The pseudo-method "multi" has been removed. Instead of, multi hops | |
263 | can be specified by the new variable `tramp-default-proxies-alist'. | |
264 | ||
265 | *** More default settings. | |
266 | Default values can be set via the variables `tramp-default-user', | |
267 | `tramp-default-user-alist' and `tramp-default-host'. | |
268 | ||
269 | *** Connection information is cached. | |
270 | In order to reduce connection setup, information about used | |
271 | connections are kept persistent in a file. The name of this file is | |
272 | defined in the variable `tramp-persistency-file-name'. | |
273 | ||
274 | *** Control of remote processes. | |
275 | Running processes on a remote host can be controlled by settings in | |
276 | `tramp-remote-path' and `tramp-remote-process-environment'. | |
277 | ||
278 | *** Success of remote copy is checked. | |
279 | When the variable `file-precious-flag' is set, the success of a remote | |
280 | file copy is checked via the file's checksum. | |
281 | ||
d15f7b68 GM |
282 | ** Miscellaneous programming mode changes |
283 | ||
da26ea8d GM |
284 | *** The file etc/emacs.py now supports both Python 2 and 3, meaning |
285 | that either version can be used as inferior Python by python.el. | |
c3f01f42 | 286 | |
d15f7b68 GM |
287 | *** The variable `fortran-line-length' can change the fixed-form line-length. |
288 | ||
b68769f2 GM |
289 | +++ |
290 | *** (The increasingly misnamed) F90 mode supports Fortran 2003 syntax. | |
2fb6c6be | 291 | |
d15f7b68 GM |
292 | ** Miscellaneous |
293 | ||
294 | *** comint-mode uses `start-file-process' now (see Lisp Changes). | |
cc213f24 MA |
295 | If `default-directory' is a remote file name, subprocesses are started |
296 | on the corresponding remote system. | |
297 | ||
d15f7b68 | 298 | *** C-x C-q in dired-mode now runs the command wdired-change-to-wdired-mode, |
40aa8257 JL |
299 | and C-x C-q in wdired-mode exits it with asking a question about |
300 | saving changes. | |
d15f7b68 | 301 | |
4596901f GM |
302 | *** The new command `eshell/info' runs info in an eshell buffer. |

8ab314f9 | 306 | |
672f99b6 JR |
307 | --- |
308 | ** IPv6 is supported on MS-Windows. | |
309 | Emacs now supports IPv6 on Windows XP and later, and earlier versions | |
310 | of Windows with third party IPv6 stacks installed. Previously IPv6 was | |
311 | supported on other platforms, but not on Windows due to using the winsock | |
312 | 1.1 header file, even though Emacs was linking to the winsock 2 library. | |

318 | ** The function `dired-call-process' has been removed. | |
319 | ||
777ea444 GM |
320 | ** The variable `byte-compile-warnings' can now be a list starting with `not', |
321 | meaning to disable the specified warnings. The meaning of this list | |
322 | may therefore be the reverse of what you expect (of course, this is | |
323 | only an issue if you make use of the new `not' syntax). Rather than | |
324 | checking/manipulating elements directly, use the new functions | |
325 | `byte-compile-warning-enabled-p', `byte-compile-disable-warning', and | |
326 | `byte-compile-enable-warning.' | |
327 | ||
74a84de2 GM |
328 | ** shell.el no longer defines the aliases `dirtrack-toggle' and |
329 | `dirtrack-mode' for `shell-dirtrack-mode'. These names were removed | |
bdf5c7d9 | 330 | because they clash with commands provided by dirtrack.el. Use |

350 | applies before function-key-map. Also it is terminal-local contrary to | |
351 | key-translation-map. Terminal-specific key-sequences are generally added to | |
352 | this map rather than to function-key-map now. | |

6168122d SM |
361 | *** $DISPLAY is now dynamically inherited from the frame's `display'. |
362 | ||
24cdde13 GM |
363 | *** The `window-system' variable has been made frame-local. The new |
364 | `initial-window-system' variable contains the `window-system' value | |
365 | for the first frame. | |
366 | ||
367 | *** You can specify a terminal device (`tty' parameter) and a terminal | |
368 | type (`tty-type' parameter) to `make-terminal-frame'. | |
369 | ||
370 | *** The new function `make-frame-on-tty' allows you to create a new | |
371 | frame on another tty device interactively. | |

384 | being suspended/resumed as a parameter. |

01ff458e | 386 | *** New function: `environment'. |
da406961 | 387 | |
4f4a84ec | 388 | *** New variable: `local-function-key-map'. |
01ff458e SM |
389 | This in addition to the global function-key-map variable that |
390 | already existed. The global variable is not used directly any more; | |
391 | instead, the local-function-key-map is initialized so as to inherit from | |
392 | function-key-map. | |
da406961 | 393 | |
82866ad5 SM |
394 | *** `initial-environment' holds the environment inherited from Emacs's parent. |
395 | ||
24cdde13 GM |
396 | *** The `keyboard-translate-table' variable and the terminal and |
397 | keyboard coding systems have been made terminal-local. | |
398 | ||
1aa423e9 SM |
399 | *** In addition to the global function-key-map, Emacs has terminal-local |
400 | local-function-key-map variables, and uses them instead of the | |
24cdde13 GM |
401 | global keymaps to set up translations and function key sequences |
402 | relevant to a specific terminal device. | |

405 | ** You can now also pass the value of the `invisible' property to invisible-p |
406 | to check whether it would cause the text to be invisible. Convenient when | |
407 | checking invisibility of text which has no buffer position | |
408 | (e.g. in before/after-strings). | |
9f44d41a | 409 | |

410 | ** Non-breaking space now acts as whitespace. |
411 | ||
41bd52f7 | 412 | +++ |
8d371994 RS |
413 | ** In `condition-case', a handler can specify "let the debugger run first". |
414 | ||
415 | You do this by writing `debug' in the list of conditions to be handled, | |
416 | like this: | |
417 | ||
418 | (condition-case nil | |
419 | (foo bar) | |
420 | ((debug error) nil)) | |
421 | ||
0a963185 SM |
422 | ** The `require-match' argument to `completing-read' accepts a new value |
423 | `confirm-only'. | |
424 | ||
c69b0314 SM |
425 | +++ |
426 | ** The regexp form \(?<num>:<regexp>\) specifies the group number explicitly. | |
427 | ||
9f44d41a RS |
428 | ** New function `window-full-width-p' returns t if a window is as wide |
429 | as its frame. | |
430 | ||
431 | ** The new function `split-string-and-unquote' does (what?) | |
432 | ||
433 | ** The new function `combine-and-quote-strings' does (what?) | |
434 | ||
435 | ** The new function `image-refresh' refreshes all images associated | |
436 | with a given image specification. | |
437 | ||
abf13a8b CY |
438 | +++ |
439 | ** New variable `user-emacs-directory'. | |
440 | Use this instead of "~/.emacs.d". | |
441 | ||
b2b387f9 | 442 | +++ |
0f3cd6b2 | 443 | ** The new function `start-file-process' is similar to `start-process', |
b2b387f9 | 444 | but obeys file handlers. The file handler is chosen based on |
6dbe7eb4 MA |
445 | `default-directory'. The functions `start-file-process-shell-command' |
446 | and `process-file-shell-command' are also new; they call internally | |
0f3cd6b2 | 447 | `start-file-process' and `process-file', respectively. |
b2b387f9 | 448 | |
64639e26 | 449 | +++ |
41bd52f7 MA |
450 | ** `file-remote-p' has new optional parameters IDENTIFICATION and CONNECTED. |
451 | IDENTIFICATION specifies which part of the remote identifier has to be | |
452 | returned. With CONNECTED passed non-nil, it is checked whether a | |
453 | remote connection has been established already. | |
64639e26 | 454 | |
45595a4f RS |
455 | ** The two new functions `looking-at-p' and `string-match-p' can do |
456 | the same matching as `looking-at' and `string-match' without changing | |
457 | the match data. | |
89835619 SM |
458 | |
459 | ** The interactive-form of a function can be added post-facto via the | |
460 | `interactive-form' symbol property. Mostly useful to add complex interactive | |
461 | forms to subroutines. | |

0bfd685e | 463 | * New Packages for Lisp Programming in Emacs 23.1 |
efeb796b | 464 | |
9097e8af RS |
465 | ** The package isearch-multi.el has been added. It implements a new mode |
466 | `isearch-buffers-minor-mode' that allows isearch to search through | |
467 | multiple buffers. In this mode a new variable | |
468 | `isearch-buffers-next-buffer-function' defines the function to call | |
469 | to get the next buffer to search in the series of multiple buffers. | |
470 | ||
d53a60a6 TTN |
471 | ** The new package avl-tree.el deals with the AVL tree data structure. |
