eb199145 | 25 | * Installation Changes in Emacs 24.1 |
09e18d03 | 26 | |
338648ad GM |
27 | ** Configure links against libselinux if it is found. |
28 | You can disable this by using --without-selinux. | |
29 | ||
30 | --- | |
31 | ** By default, the installed Info and man pages are compressed. | |
32 | You can disable this by configuring --without-compress-info. | |
33 | ||
aded53ff GM |
34 | --- |
35 | ** There are new configure options: | |
36 | --with-mmdf, --with-mail-unlink, --with-mailhost. | |
37 | These provide no new functionality, they just remove the need to edit | |
38 | lib-src/Makefile by hand in order to use the associated features. | |
39 | ||
e547b051 | 40 | --- |
30c4d8dc | 41 | ** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
e547b051 J |
42 | to configure. Note that other libraries used by Emacs, RSVG and GConf, |
43 | also depend on Gtk+. You can disable them with --without-rsvg and | |
44 | --without-gconf. | |
45 | ||
3fd50d5c | 46 | --- |
d9170db5 DN |
47 | ** There is a new configure option --enable-use-lisp-union-type. |
48 | This is only useful for Emacs developers to debug certain types of bugs. | |
b2957ea8 | 49 | This is not a new feature; only the configure flag is new. |
d9170db5 | 50 | |
3fd50d5c | 51 | --- |
81eafe29 PE |
52 | ** There is a new configure option --with-wide-int. |
53 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. | |
0a768890 PE |
54 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB |
55 | to about 2 GiB. | |
81eafe29 | 56 | |
d064e6a6 | 57 | --- |
f042970d | 58 | ** New translation of the Emacs Tutorial in Hebrew is available. |
d064e6a6 EZ |
59 | Type `C-u C-h t' to choose it in case your language setup doesn't |
60 | automatically select it. | |
61 | ||
ddb54206 | 62 | ** Emacs can be compiled with ImageMagick support. |
041d709f | 63 | Emacs links to ImageMagick if version 6.2.8 or newer of the library is |
ddb54206 CY |
64 | present at build time. To inhibit ImageMagick, use the configure |
65 | option `--without-imagemagick' . | |
041d709f | 66 | |
ddb54206 | 67 | --- |
041d709f CY |
68 | ** The standalone programs digest-doc and sorted-doc are removed. |
69 | Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'. | |
70 | ||
71 | --- | |
72 | ** The standalone program `fakemail' is removed. | |
73 | If you need it, feedmail.el provides a superset of the functionality. | |

eb199145 | 76 | * Startup Changes in Emacs 24.1 |
4a263588 | 77 | |
fdeb32ec | 78 | --- |
198a7a97 | 79 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte |
adbf62ff GM |
80 | command line arguments, and the EMACS_UNIBYTE environment variable, no |
81 | longer have any effect. (They were declared obsolete in Emacs 23.) | |
198a7a97 | 82 | |
fdeb32ec | 83 | +++ |
66b7b0fe GM |
84 | ** New command line option `--no-site-lisp' removes site-lisp directories |
85 | from load-path. -Q now implies this. | |

3fd50d5c | 90 | +++ |
041d709f | 91 | ** auto-mode-case-fold is now enabled by default. |
2a847524 | 92 | |
a2a25d24 | 93 | ** Completion |
fdeb32ec | 94 | |
e17d9003 | 95 | *** shell-mode uses pcomplete rules, with the standard completion UI. |
3d992aa0 | 96 | +++ |
de0bde62 CY |
97 | *** Many packages have been changed to use `completion-at-point' |
98 | rather than their own completion code. | |
3d992aa0 | 99 | +++ |
de0bde62 | 100 | *** `completion-at-point' now handles tags and semantic completion. |
27a16462 | 101 | --- |
a2a25d24 SM |
102 | *** Completion in a non-minibuffer now tries to detect the end of completion |
103 | and pops down the *Completions* buffer accordingly. | |
de09aa52 | 104 | +++ |
a2a25d24 | 105 | *** Completion can cycle, depending on completion-cycle-threshold. |
27a16462 | 106 | +++ |
a2a25d24 | 107 | *** New completion style `substring'. |
939db9ac | 108 | +++ |
620c53a6 | 109 | *** Completion style can be set per-category `completion-category-overrides'. |
939db9ac | 110 | +++ |
620c53a6 SM |
111 | *** Completion of buffers now uses substring completion by default. |
112 | ||
6870aaef LMI |
113 | ** Mail changes |
114 | ||
b30941db CY |
115 | +++ |
116 | *** The default of `send-mail-function' is now `sendmail-query-once', | |
041d709f CY |
117 | which asks the user (once) whether to use the smtpmail package to send |
118 | email, or to use the old defaults that rely on external mail | |
119 | facilities (`sendmail-send-it' on GNU/Linux and other Unix-like | |
120 | systems, and `mailclient-send-it' on Windows). | |
6870aaef | 121 | |
041d709f | 122 | *** smtpmail changes |
95f41d9a | 123 | |
041d709f CY |
124 | **** smtpmail now uses encrypted connections (via STARTTLS) if the |
125 | mail server supports them. It also uses the auth-source framework for | |
126 | getting credentials. | |
95f41d9a | 127 | |
041d709f CY |
128 | **** The variable `smtpmail-auth-credentials' has been removed. |
129 | That variable used to have the default value "~/.authinfo", in which | |
130 | case you won't see any difference. But if you changed it to be a list | |
131 | of user names and passwords, that setting is now ignored; you will be | |
132 | prompted for the user name and the password, which will then be saved | |
ffdcbd1c LMI |
133 | to ~/.authinfo. (To control where and how the credentials are stored, |
134 | see the auth-source manual. You may want to change the auth-source | |
135 | preferences if you want to store the credentials encrypted, for | |
136 | instance.) | |
e2430e31 | 137 | |
041d709f CY |
138 | You can also manually copy the credentials to your ~/.authinfo file. |
139 | For example, if you had | |
e2430e31 | 140 | |
041d709f CY |
141 | (setq smtpmail-auth-credentials |
142 | '(("mail.example.org" 25 "jim" "s!cret"))) | |
e2430e31 LMI |
143 | |
144 | then the equivalent line in ~/.authinfo would be | |
145 | ||
041d709f CY |
146 | machine mail.example.org port 25 login jim password s!cret |
147 | ||
148 | **** The variable `smtpmail-starttls-credentials' has been removed. | |
95f41d9a | 149 | |
cd1181db | 150 | If you had that set, then you need to put |
95f41d9a | 151 | |
041d709f | 152 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert" |
95f41d9a LMI |
153 | |
154 | in your ~/.authinfo file instead. | |
155 | ||
b30941db | 156 | *** Mail mode changes (this is the old Mail mode, not Message mode) |
c3760c17 | 157 | +++ |
b30941db | 158 | **** New command `mail-add-attachment' for adding MIME attachments |
c3760c17 | 159 | --- |
b30941db CY |
160 | **** The command `mail-attach-file' was renamed to `mail-insert-file'. |
161 | The old name is now an obsolete alias to the new name. | |
c3760c17 | 162 | |
041d709f | 163 | ** Emacs server and client changes |
ddb54206 | 164 | +++ |
041d709f CY |
165 | *** New option `server-port' specifies the port on which the Emacs |
166 | server should listen. | |
167 | +++ | |
168 | *** New emacsclient argument -q/--quiet suppresses some status messages. | |
169 | +++ | |
170 | *** New emacsclient argument --frame-parameters can be used to set the | |
171 | frame parameters of a newly-created graphical frame. | |
172 | +++ | |
8350f087 | 173 | *** If emacsclient shuts down as a result of Emacs signaling an |
041d709f CY |
174 | error, its exit status is 1. |
175 | +++ | |
176 | *** New emacsclient argument --parent-id ID. | |
177 | This opens a client frame in parent X window ID, via XEmbed, similar | |
178 | to the --parent-id argument to Emacs. | |
179 | ||

180 | ** Internationalization changes |
181 | ||
f4b6ba46 | 182 | +++ |
d0ce9f8c | 183 | *** Emacs now supports display and editing of bidirectional text. |
f4b6ba46 | 184 | |
f1816485 EZ |
185 | Text that includes characters from right-to-left (RTL) scripts, such |
186 | as Arabic, Farsi, or Hebrew, is displayed in the correct visual order | |
187 | as expected by users of those scripts. This display reordering is a | |
188 | "Full bidirectionality" class implementation of the Unicode | |
7850ac23 EZ |
189 | Bidirectional Algorithm. Buffers with no RTL text should look exactly |
190 | the same as before. | |
f4b6ba46 | 191 | |
041d709f CY |
192 | For more information, see the node "Bidirectional Editing" in the |
193 | Emacs Manual. | |
f4b6ba46 | 194 | |
041d709f CY |
195 | +++ |
196 | **** New buffer-local variable `bidi-display-reordering'. | |
197 | To disable display reordering in any given buffer, change this to nil. | |
d20e1419 | 198 | |
041d709f CY |
199 | +++ |
200 | **** New buffer-local variable `bidi-paragraph-direction'. | |
201 | If nil (the default), Emacs determines the base direction of each | |
202 | paragraph from its text, as specified by the Unicode Bidirectional | |
f4b6ba46 EZ |
203 | Algorithm. |
204 | ||
041d709f CY |
205 | Setting this to `right-to-left' or `left-to-right' forces a particular |
206 | base direction on each paragraph in the buffer. | |
207 | ||
f1816485 EZ |
208 | Paragraphs whose base direction is right-to-left are displayed |
209 | starting at the right margin of the window. | |
210 | ||
d0ce9f8c | 211 | +++ |
041d709f CY |
212 | *** Enhanced support for characters with no glyphs in available fonts. |
213 | If a character has no glyphs in any of the available fonts, Emacs | |
214 | normally displays it either as a hexadecimal code in a box or as a | |
d0ce9f8c MB |
215 | thin 1-pixel space. In addition to these two methods, Emacs can |
216 | display these characters as empty box, as an acronym, or not display | |
217 | them at all. To change how these characters are displayed, customize | |
218 | the variable `glyphless-char-display-control'. | |
219 | ||
041d709f | 220 | On character terminals, these methods are used for characters that |
d0ce9f8c MB |
221 | cannot be encoded by the `terminal-coding-system'. |
222 | ||
ddb54206 | 223 | --- |
041d709f CY |
224 | *** New input methods for Farsi: farsi and farsi-translit. |
225 | ||
939db9ac CY |
226 | +++ |
227 | *** `nobreak-char-display' now also highlights Unicode hyphen chars | |
228 | (U+2010 and U+2011). | |
229 | ||
041d709f | 230 | ** Improved GTK integration |
da97a9e6 | 231 | +++ |
041d709f | 232 | *** GTK scroll-bars are now placed on the right by default. |
52834b6b | 233 | Use `set-scroll-bar-mode' to change this. |
da97a9e6 | 234 | +++ |
041d709f | 235 | *** GTK tool bars can have just text, just images or images and text. |
d8004abe | 236 | Customize `tool-bar-style' to choose style. On a Gnome desktop, the default |
20fe03ad | 237 | is taken from the desktop settings. |
da97a9e6 | 238 | --- |
041d709f | 239 | *** GTK tool bars can be placed on the left/right or top/bottom of the frame. |
8b2dd508 | 240 | The frame-parameter tool-bar-position controls this. It takes the values |
1c0d77cc | 241 | top, left, right or bottom. The Options => Show/Hide menu has entries |
8b2dd508 | 242 | for this. |
d366bd53 | 243 | +++ |
67e729a5 CY |
244 | *** The colors for selected text (the `region' face) are taken from |
245 | the GTK theme when Emacs is built with GTK. | |
d366bd53 | 246 | +++ |
041d709f CY |
247 | *** Emacs uses GTK tooltips by default if built with GTK. You can turn that |
248 | off by customizing x-gtk-use-system-tooltips. | |
16a91140 | 249 | |
35137ed3 | 250 | +++ |
bc987f8b JL |
251 | ** New basic faces `error', `warning', `success' are available to |
252 | highlight strings that indicate failure, caution or successful operation. | |
253 | ||
b22b1918 | 254 | --- |
1ecb2d3f | 255 | ** Lucid menus and dialogs can display antialiased fonts if Emacs is built |
3928f2b6 JD |
256 | with Xft. To change font, use the X resource font, for example: |
257 | Emacs.pane.menubar.font: Courier-12 | |
99852628 | 258 | |
21100e7d | 259 | +++ |
917794d5 | 260 | ** On graphical displays, the mode-line no longer ends in dashes. |
1dd3c2d9 CY |
261 | Also, the first dash (which does not indicate anything) is just |
262 | displayed as a space. | |
917794d5 | 263 | |
b7d65a5f GM |
264 | ** Basic SELinux support has been added. |
265 | This requires Emacs to be linked with libselinux at build time. | |
266 | ||
d8004abe GM |
267 | *** Emacs preserves the SELinux file context when backing up, and |
268 | optionally when copying files. To this end, copy-file has an extra | |
269 | optional argument, and backup-buffer and friends include the SELinux | |
270 | context in their return values. | |
b7d65a5f GM |
271 | |
272 | *** The new functions file-selinux-context and set-file-selinux-context | |
273 | get and set the SELinux context of a file. | |
bfd779dd | 274 | --- |
a5bee597 MA |
275 | *** Tramp offers handlers for file-selinux-context and set-file-selinux-context |
276 | for remote machines which support SELinux. | |
277 | ||
041d709f | 278 | ** Changes for exiting Emacs |
ddb54206 | 279 | +++ |
041d709f CY |
280 | *** The function kill-emacs is now run upon receipt of the signals |
281 | SIGTERM and SIGHUP, and upon SIGINT in batch mode. | |
ddb54206 | 282 | +++ |
041d709f | 283 | *** kill-emacs-hook is now also run in batch mode. |
63c72eeb GM |
284 | If you have code that adds something to kill-emacs-hook, you should |
285 | consider if it is still appropriate to add it in the noninteractive case. | |
9c524fcb | 286 | |
041d709f | 287 | ** Scrolling changes |
550f41cd | 288 | +++ |
041d709f | 289 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' |
0a19a6f8 JB |
290 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
291 | of buffer at first key-press (instead move to top/bottom of buffer) | |
550f41cd | 292 | when `scroll-error-top-bottom' is non-nil. |
550f41cd CY |
293 | +++ |
294 | *** New variable `scroll-error-top-bottom' (see above). | |
e7a3ff06 | 295 | +++ |
041d709f | 296 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' |
5a97d2da | 297 | scroll a line instead of full screen. |
550f41cd | 298 | +++ |
041d709f | 299 | *** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 300 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
d0f69533 | 301 | +++ |
041d709f | 302 | *** If you customize `scroll-conservatively' to a value greater than 100, |
d0f69533 EZ |
303 | Emacs will never recenter point in the window when it scrolls due to |
304 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | |
305 | Previously, you needed to use `most-positive-fixnum' as the value of | |
306 | `scroll-conservatively' to achieve the same effect. | |
d0f69533 | 307 | --- |
041d709f | 308 | *** ``Aggressive'' scrolling now honors the scroll margins. |
d0f69533 EZ |
309 | If you customize `scroll-up-aggressively' or |
310 | `scroll-down-aggressively' and move point off the window, Emacs now | |
311 | scrolls the window so as to avoid positioning point inside the scroll | |
312 | margin. | |
313 | ||
f1a5d776 | 314 | ** Trash changes |
04e2ce72 | 315 | +++ |
f1a5d776 CY |
316 | *** `delete-by-moving-to-trash' now only affects commands that specify |
317 | trashing. This avoids inadvertently trashing temporary files. | |
04e2ce72 | 318 | +++ |
f1a5d776 CY |
319 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
320 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
321 | ||
f0bf7c8e JL |
322 | ** New option `list-colors-sort' defines the color sort order |
323 | for `list-colors-display'. | |
324 | ||
44198b6e CY |
325 | ** An Emacs Lisp package manager is now included. |
326 | This is a convenient way to download and install additional packages, | |
3fd50d5c | 327 | from a package repository at http://elpa.gnu.org. |
d43f5a42 | 328 | +++ |
cb6c4991 CY |
329 | *** `M-x list-packages' shows a list of packages, which can be |
330 | selected for installation. | |
d43f5a42 | 331 | +++ |
cb6c4991 | 332 | *** New command `describe-package', bound to `C-h P'. |
d43f5a42 | 333 | +++ |
44198b6e CY |
334 | *** By default, all installed packages are loaded and activated |
335 | automatically when Emacs starts up. To disable this, set | |
336 | `package-enable-at-startup' to nil. To change which packages are | |
337 | loaded, customize `package-load-list'. | |

f065864f | 339 | ** Custom Themes |
b0d7d8af | 340 | +++ |
f065864f | 341 | *** `M-x customize-themes' lists Custom themes which can be enabled. |
b0d7d8af | 342 | +++ |
782b5e8d CY |
343 | *** New option `custom-theme-load-path' is the load path for themes. |
344 | Emacs no longer looks for custom themes in `load-path'. The default | |
345 | is to search in `custom-theme-directory', followed by a built-in theme | |
346 | directory named "themes/" in `data-directory'. | |
b0d7d8af | 347 | +++ |
b7617f6d CY |
348 | *** New option `custom-safe-themes' records known-safe theme files. |
349 | If a theme is not in this list, Emacs queries before loading it, and | |
350 | offers to save the theme to `custom-safe-themes' automatically. By | |
351 | default, all themes included in Emacs are treated as safe. | |

481 | ** Selection changes. |
482 | ||
b1ab31ae CY |
483 | The default handling of clipboard and primary selections was changed |
484 | to conform with modern X applications. In short, most commands for | |
485 | killing and yanking text now use the clipboard, while mouse commands | |
486 | use the primary selection. | |
487 | ||
488 | In the following, we provide a list of these changes, followed by a | |
489 | list of steps to get the old behavior back if you prefer that. | |
490 | ||
963578d3 | 491 | +++ |
b1ab31ae CY |
492 | *** `select-active-regions' now defaults to t. |
493 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
963578d3 | 494 | the kill ring. The selected text is put in the primary selection, if |
b1ab31ae CY |
495 | the system possesses a separate primary selection facility (e.g. X). |
496 | ||
963578d3 | 497 | +++ |
b1ab31ae CY |
498 | **** `select-active-regions' also accepts a new value, `only'. |
499 | This means to only set the primary selection for temporarily active | |
500 | regions (usually made by mouse-dragging or shift-selection); | |
501 | "ordinary" active regions, such as those made with C-SPC followed by | |
502 | point motion, do not alter the primary selection. | |
503 | ||
963578d3 CY |
504 | --- |
505 | **** `mouse-drag-copy-region' now defaults to nil. | |
506 | ||
507 | +++ | |
b1ab31ae CY |
508 | *** mouse-2 is now bound to `mouse-yank-primary'. |
509 | This pastes from the primary selection, ignoring the kill-ring. | |
510 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
511 | ||
963578d3 | 512 | +++ |
b1ab31ae | 513 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
963578d3 | 514 | +++ |
b1ab31ae CY |
515 | *** `x-select-enable-primary' now defaults to nil. |
516 | Thus, commands that kill text or copy it to the kill-ring (such as | |
517 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
518 | ||
963578d3 | 519 | --- |
b1ab31ae CY |
520 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now |
521 | exactly equivalent to, respectively M-w, C-w, and C-y. | |
522 | ||
963578d3 | 523 | --- |
b1ab31ae CY |
524 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already |
525 | non-nil by default, as Windows does not support the primary selection | |
526 | between applications. | |
527 | ||
963578d3 | 528 | --- |
b1ab31ae | 529 | *** To return to the previous behavior, do the following: |
104c2fe9 | 530 | **** Change `select-active-regions' to nil. |
b1ab31ae CY |
531 | **** Change `mouse-drag-copy-region' to t. |
532 | **** Change `x-select-enable-primary' to t (on X only). | |
533 | **** Change `x-select-enable-clipboard' to nil. | |
534 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 535 | |

537 | *** Support for X cut buffers has been removed. |

99f053cf | 543 | ** New command `rectangle-number-lines', bound to `C-x r N', numbers |
6b2c221e | 544 | the lines in the current rectangle. With a prefix argument, this |
99f053cf JA |
545 | prompts for a number to count from and for a format string. |

6bf7006f | 547 | +++ |
db7ab02f | 548 | ** The default value of redisplay-dont-pause is now t |
6bf7006f EZ |
549 | This makes Emacs feel more responsive to editing commands that arrive |
550 | at high rate, e.g. if you lean on some key, because stopping redisplay | |
551 | in the middle (when this variable is nil) forces more expensive | |
552 | updates later on, and Emacs appears to be unable to keep up. | |
553 | ||
e70b5064 CY |
554 | +++ |
555 | ** The behavior of <TAB> for active regions in Text mode has changed. | |
556 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | |
557 | when the region is active causes Emacs to indent all the lines in the | |
558 | region, aligning them with the line previous to the first line in the | |
559 | region (or with the left margin if there is no previous line). | |

762 | ** SQL Mode enhancements. |
763 | ||
764 | *** `sql-dialect' is an alias for `sql-product'. | |
765 | ||
766 | *** New variable `sql-port' specifies the port number for connecting | |
767 | to a MySQL or Postgres server. | |
768 | ||
769 | *** The command `sql-product-interactive' now takes a prefix argument, | |
770 | which causes it to prompt for an SQL product instead of the current | |
771 | value of `sql-product'. | |
772 | ||
773 | *** Product-specific SQL interactive commands now take prefix args. | |
774 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), | |
775 | given a prefix argument, prompt for a name for the SQL interactive | |
776 | buffer. This reduces the need for calling `sql-rename-buffer'. | |
777 | ||
778 | *** SQL interactive modes suppress command continuation prompts, and | |
779 | replace tabs with spaces. The first change impacts multiple line SQL | |
780 | statements entered with C-j between each line, statements yanked into | |
781 | the buffer and statements sent with `sql-send-*' functions. The | |
782 | second change prevents the MySQL and Postgres interpreters from | |
783 | listing object name completions when sent text via `sql-send-*' | |
784 | functions. | |
785 | ||
786 | *** New custom variables control prompting for login parameters. | |
787 | Each supported product has a custom variable `sql-*-login-params', | |
788 | which is a list of the parameters to be prompted for before a | |
789 | connection is established. | |
790 | ||
791 | *** New variable `sql-connection-alist' for login parameter values. | |
792 | This can be used to store different username, database and server | |
793 | values. Connections defined in this variable appear in the submenu | |
794 | SQL->Start... for making new SQLi sessions. | |
795 | ||
796 | *** New command `sql-connect' starts a predefined SQLi session, | |
797 | using the login parameters from `sql-connection-alist'. | |
798 | ||
799 | *** New "Save Connection" menu item in SQLi buffers. | |
800 | This gathers the login params specified for the SQLi session, if it | |
801 | was not started by a connection, and saves them as a new connection. | |
802 | ||
803 | *** Commands for listing database objects and details. | |
804 | In an SQLi session, you can get a list of objects in the database. | |
805 | The contents of these lists are product specific. | |
806 | ||
807 | **** `C-c C-l a' or the "SQL->List all objects" menu item | |
808 | lists all the objects in the database. With a prefix argument, it | |
809 | displays additional details or extend the listing to include other | |
810 | schemas objects. | |
811 | ||
812 | **** `C-c C-l t' or the "SQL->List Table details" menu item | |
813 | prompts for the name of a database table or view and displays the list | |
814 | of columns in the relation. With a prefix argument, it displays | |
815 | additional details about each column. | |
816 | ||
817 | *** New options `sql-send-terminator' and `sql-oracle-scan-on'. | |

1055 | *** New function `bidi-string-mark-left-to-right'. | |
f1816485 EZ |
1056 | Given a string containing characters from right-to-left (RTL) scripts, |
1057 | this function returns another string which can be safely inserted into | |
1058 | a buffer, such that any following text will be always displayed to the | |
1059 | right of that string. (This works by appending the Unicode | |
1060 | "LEFT-TO-RIGHT MARK" character when the argument string might need that.) | |
041d709f CY |

1062 | This is useful when the buffer has overall left-to-right (LTR) | |
1063 | paragraph direction and you need to insert a string whose contents and | |

1096 | set to any of the values 'below, 'right, 'above, or 'left to make the | |
1097 | new window appear on the corresponding side of the window that shall be | |

1110 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | |
1111 | is able to resize other windows if a window adjacent to the trailing | |
1112 | edge cannot be shrunk any more. This makes its behavior more similar to | |
1113 | that of Emacs 21 without compromising, however, its inability to delete | |
1114 | windows which was introduced in Emacs 22. | |
c4682d18 MR |
1115 | +++ |
1116 | *** Window-local buffer lists. | |
1117 | Windows now have local buffer lists. This means that removing a buffer | |

1124 | which if non-nil requires the buffer to be displayed in the currently | |

1134 | **** The second arg to `display-buffer' and `pop-to-buffer' is now | |
1135 | named ACTION, and takes a display action of the same form as | |
1136 | `display-buffer-base-action' (see Changes, above). A non-nil, | |
1137 | non-list value is treated specially, as the old meaning. | |
1138 | ||
1139 | **** New variable `display-buffer-overriding-action'. | |
1140 | ||
1141 | **** The procedure of `display-buffer' etc. to choose a window is | |
1142 | determined by combining `display-buffer-overriding-action', | |
1143 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', | |
1144 | and `display-buffer-fallback-action'. The second and fourth of these | |
1145 | are user-customizable variables. | |

041d709f | 1165 | |
a2a25d24 SM |
1166 | *** New variable completion-extra-properties used to specify extra properties |
1167 | of the current completion: | |
1168 | - :annotate-function, same as the old completion-annotate-function. | |
1169 | - :exit-function, function to call after completion took place. | |
1170 | ||
1171 | *** Functions on completion-at-point-functions can return any of the properties | |
1172 | valid for completion-extra-properties. | |
1173 | ||
1174 | *** completion-annotate-function is obsolete. | |
1175 | ||
620c53a6 SM |
1176 | *** New `metadata' method for completion tables. The metadata thus returned |
1177 | can specify various details of the data returned by `all-completions': | |
1178 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | |
1179 | used to select a style in completion-category-overrides. | |
1180 | - `annotation-function' to add annotations in *Completions*. | |
1181 | - `display-sort-function' to specify how to sort entries in *Completions*. | |
1182 | - `cycle-sort-function' to specify how to sort entries when cycling. | |
1183 | ||
de09aa52 CY |
1184 | *** minibuffer-local-filename-must-match-map is not used any more. |
1185 | Instead, the bindings in minibuffer-local-filename-completion-map are | |
1186 | combined with minibuffer-local-must-match-map. | |
1187 | ||
1188 | *** New variable `completing-read-function' allows overriding the | |
1189 | behavior of `completing-read'. | |

da91b5f2 CY |
1195 | ** `open-network-stream' can now be used to open an encrypted stream. |
1196 | It now accepts an optional `:type' parameter for initiating a TLS | |
1197 | connection, directly or via STARTTLS. To do STARTTLS, additional | |
1198 | parameters (`:end-of-command', `:success', `:capabilities-command') | |

e7f7fbaa SM |
1221 | Also the debugger can now "continue" from an error, which means it will jump |
1222 | to the error handler as if the debugger had not been invoked instead of | |
1223 | jumping all the way to the top-level. | |

1230 | discarding any inputs not inside the set. | |
1231 | ||
2e288d54 JB |
1232 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
1233 | The variable is now used to load all kind of supported dynamic libraries, | |
1234 | not just image libraries. The previous name is still available as an | |
1235 | obsolete alias. | |
1236 | ||
04e2ce72 CY |
1237 | ** New variable `syntax-propertize-function'. |
1238 | This replaces `font-lock-syntactic-keywords' which is now obsolete. | |
cf38dd42 SM |
1239 | This allows syntax-table properties to be set independently from font-lock: |
1240 | just call syntax-propertize to make sure the text is propertized. | |
1241 | Together with this new variable come a new hook | |
1242 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
1243 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
1244 | as-is; and syntax-propertize-rules which provides a new way to specify | |
1245 | syntactic rules. | |

1257 | should be derived. | |
041d709f | 1258 | |
15de15c6 CY |
1259 | **** `prog-mode-hook' can be used to enable features for programming |
1260 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable | |
1261 | on-the-fly spell checking for comments and strings. | |

b2957ea8 | 1272 | ** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
1273 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
1274 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
1275 | argument is supplied (see Trash changes, above). | |
53967e09 | 1276 | |
9317e499 CY |
1277 | ** `facemenu-read-color' is now an alias for `read-color'. |
1278 | The command `read-color' now requires a match for a color name or RGB | |
8350f087 | 1279 | triplet, instead of signaling an error if the user provides a invalid |
9317e499 CY |
1280 | input. |
1281 | ||
4039c786 CY |
1282 | ** Tool-bars can display separators. |

1294 | **** `image-animate-timer' returns the timer object for an image that | |
1295 | is being animated. | |
00fe2df1 | 1296 | |
1546c559 JL |
1297 | *** `image-extension-data' is renamed to `image-metadata'. |

041d709f CY |
1299 | *** If Emacs is compiled with ImageMagick support (see Startup |
1300 | Changes), the function `imagemagick-types' returns a list of image | |
1301 | file extensions that your installation of ImageMagick supports. The | |

1317 | ** GnuTLS |
1318 | ||
1319 | *** Emacs can be compiled with libgnutls support | |
1320 | This is the default. You will then be able to use the functionality | |
1321 | in gnutls.el, namely the `open-gnutls-stream' and `gnutls-negotiate' | |
1322 | functions. It's easiest to use these functions through | |
1323 | `open-network-stream' because it can upgrade connections through | |
1324 | STARTTLS opportunistically or use plain SSL, depending on your needs. | |
1325 | ||
1326 | Only versions 2.8.x and higher or GnuTLS have been tested. | |
9f77899d GM |
1327 | [FIXME: this statement needs clarifying, given that GnuTLS >= 2.6.6 |
1328 | is the test used by configure.] | |
e2574f2c TZ |

1330 | *** gnutls-log-level | |
1331 | Set `gnutls-log-level' higher than 0 to get debug output. 1 is for | |
1332 | important messages, 2 is for debug data, and higher numbers are as per | |

1340 | ** Progress reporters can now "spin". |
1341 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
