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. | |

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. | |

46 | ** There is a new configure option --enable-use-lisp-union-type. |
47 | This is only useful for Emacs developers to debug certain types of bugs. | |
b2957ea8 | 48 | This is not a new feature; only the configure flag is new. |

fd6fa53f SM |
77 | ** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. |
78 | This is handy for minibuffer-only frames, and is also used for the "mouse-1 | |
79 | pops up *Messages*" feature, which can now easily be changed. | |
80 | ||
2a847524 CY |
81 | ** emacsclient changes |
82 | ||
fdeb32ec | 83 | +++ |
2a847524 | 84 | *** New emacsclient argument --parent-id ID can be used to open a |
0191e222 CY |
85 | client frame in parent X window ID, via XEmbed. This works like the |
86 | --parent-id argument to Emacs. | |
87 | ||
15a7a774 | 88 | +++ |
d862b746 GM |
89 | *** New emacsclient argument -q/--quiet suppresses some status messages. |
90 | ||
18a4ce5e AR |
91 | +++ |
92 | *** New emacsclient argument --frame-parameters can be used to set the | |
93 | frame parameters of a newly-created graphical frame. | |
94 | ||
fdeb32ec | 95 | +++ |
2a847524 CY |
96 | *** If emacsclient shuts down as a result of Emacs signalling an |
97 | error, its exit status is 1. | |
98 | ||
a2a25d24 | 99 | ** Completion |
fdeb32ec | 100 | |
e17d9003 SM |
101 | *** shell-mode uses pcomplete rules, with the standard completion UI. |
102 | ||
a2a25d24 SM |
103 | *** Many packages have been changed to use completion-at-point rather than |
104 | their own completion code. | |
105 | ||
106 | *** Completion in a non-minibuffer now tries to detect the end of completion | |
107 | and pops down the *Completions* buffer accordingly. | |
108 | ||
109 | *** Completion can cycle, depending on completion-cycle-threshold. | |
902a6d8d | 110 | |
a2a25d24 SM |
111 | *** New completion style `substring'. |
112 | ||
620c53a6 SM |
113 | *** Completion style can be set per-category `completion-category-overrides'. |
114 | ||
115 | *** Completion of buffers now uses substring completion by default. | |
116 | ||
a2a25d24 | 117 | *** `completing-read' can be customized using the new variable |
f042970d | 118 | `completing-read-function'. |
3ec03f7e | 119 | |
3349e122 SM |
120 | *** minibuffer-local-filename-must-match-map is not used any more. |
121 | Instead, the bindings in minibuffer-local-filename-completion-map are combined | |
122 | with minibuffer-local-must-match-map. | |
123 | ||
2372f278 SM |
124 | ** auto-mode-case-fold is now enabled by default. |
125 | ||
6870aaef LMI |
126 | ** Mail changes |
127 | ||
128 | The default of `send-mail-function' has changed from | |
129 | `sendmail-send-it' (on GNU/Linux and other Unix-like systems) or | |
130 | `mailclient-send-it' (on Windows) to `sendmail-query-once'. This new | |
131 | default will ask the user (once) whether to use the internal smtpmail | |
132 | package to send email, or to use the old, external defaults. | |
133 | ||
95f41d9a LMI |
134 | ** smtpmail changes |
135 | ||
6870aaef | 136 | *** smtpmail has been largely rewritten to upgrade to STARTTLS if |
95f41d9a LMI |
137 | possible, and uses the auth-source framework for getting credentials. |
138 | The rewrite should be largely compatible with previous versions of | |
139 | smtpmail, but there are two major incompatibilities: | |
140 | ||
6870aaef | 141 | *** `smtpmail-auth-credentials' no longer exists. That variable used |
e2430e31 | 142 | to be be either ~/.authinfo (in which case you won't see any |
95f41d9a | 143 | difference), but if it were a direct list of user names and passwords, |
e2430e31 LMI |
144 | it will be ignored, and you will be prompted for the user name and the |
145 | password instead. They will then be saved to ~/.authinfo. | |
146 | ||
147 | If you wish to copy over all the credentials from | |
148 | `smtpmail-auth-credentials' to your ~/.authinfo file manually, instead | |
149 | of letting smtpmail prompt you for these values, that's also possible. | |
150 | ||
151 | If you had, for instance, | |
152 | ||
153 | (setq smtpmail-auth-credentials | |
154 | '(("mail.example.org" 25 "jim" "s!cret"))) | |
155 | ||
156 | then the equivalent line in ~/.authinfo would be | |
157 | ||
158 | machine mail.example.org port 25 login jim password s!cret | |
95f41d9a | 159 | |
6870aaef | 160 | *** Similarly, `smtpmail-starttls-credentials' no longer exists. If |
e2430e31 | 161 | you had that set, then then you need to put |
95f41d9a | 162 | |
e2430e31 LMI |
163 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert |
164 | "~/.my_smtp_tls.cert" | |
95f41d9a LMI |
165 | |
166 | in your ~/.authinfo file instead. | |

168 | ** Internationalization changes |
169 | ||
f4b6ba46 | 170 | +++ |
d0ce9f8c | 171 | *** Emacs now supports display and editing of bidirectional text. |
f4b6ba46 EZ |
172 | |
173 | See the node "Bidirectional Editing" in the Emacs Manual for some | |
7a2f5f30 | 174 | additional documentation. |
f4b6ba46 EZ |
175 | |
176 | To turn this on in any given buffer, set the buffer-local variable | |
177 | `bidi-display-reordering' to a non-nil value. The default is nil. | |
178 | ||
179 | The buffer-local variable `bidi-paragraph-direction', if non-nil, | |
180 | forces each paragraph in the buffer to have its base direction | |
181 | according to the value of this variable. Possible values are | |
182 | `right-to-left' and `left-to-right'. If the value is nil (the | |
183 | default), Emacs determines the base direction of each paragraph from | |
184 | its text, as specified by the Unicode Bidirectional Algorithm. | |
185 | ||
d20e1419 EZ |
186 | The function `current-bidi-paragraph-direction' returns the actual |
187 | value of paragraph base direction at point. | |
188 | ||
f4b6ba46 EZ |
189 | Reordering of bidirectional text for display in Emacs is a "Full |
190 | bidirectionality" class implementation of the Unicode Bidirectional | |
191 | Algorithm. | |
192 | ||
d0ce9f8c MB |
193 | +++ |
194 | *** Enhanced support for characters that have no glyphs in available fonts. | |
195 | If a character has no glyphs in any of the available fonts, Emacs by | |
196 | default will display it either as a hexadecimal code in a box or as a | |
197 | thin 1-pixel space. In addition to these two methods, Emacs can | |
198 | display these characters as empty box, as an acronym, or not display | |
199 | them at all. To change how these characters are displayed, customize | |
200 | the variable `glyphless-char-display-control'. | |
201 | ||
202 | On character terminals these methods are used for characters that | |
203 | cannot be encoded by the `terminal-coding-system'. | |
204 | ||
205 | *** There are two new input methods for Persian/Farsi: farsi and farsi-translit. | |
206 | ||
303500aa | 207 | ** GTK scroll-bars are now placed on the right by default. |
52834b6b CY |
208 | Use `set-scroll-bar-mode' to change this. |
209 | ||
20fe03ad | 210 | ** GTK tool bars can have just text, just images or images and text. |
d8004abe | 211 | Customize `tool-bar-style' to choose style. On a Gnome desktop, the default |
20fe03ad JD |
212 | is taken from the desktop settings. |
213 | ||
8b2dd508 JD |
214 | ** GTK tool bars can be placed on the left/right or top/bottom of the frame. |
215 | The frame-parameter tool-bar-position controls this. It takes the values | |
1c0d77cc | 216 | top, left, right or bottom. The Options => Show/Hide menu has entries |
8b2dd508 JD |
217 | for this. |
218 | ||
8740c12d | 219 | ** ImageMagick support. |
b2fa3a09 GM |
220 | It is now possible to use the ImageMagick library to load many new |
221 | image formats in Emacs. By default, Emacs links with the ImageMagick | |
f5b06c35 GM |
222 | libraries if they are present at build time. This needs ImageMagick |
223 | 6.2.8 or newer (versions newer than 6.0.7 _may_ work but have not been | |
224 | tested). To disable ImageMagick support, use the configure option | |
fa6996bc | 225 | `--without-imagemagick'. |
16a91140 | 226 | |
8740c12d GM |
227 | The new function `imagemagick-types' returns a list of image file |
228 | extensions that your installation of ImageMagick supports. The | |
229 | function `imagemagick-register-types' enables ImageMagick support for | |
b2957ea8 | 230 | these image types, minus those listed in `imagemagick-types-inhibit'. |
16a91140 | 231 | |
8740c12d | 232 | See the Emacs Lisp Reference Manual for more information. |
16a91140 | 233 | |
3a46642b J |
234 | ** The colors for selected text (the region face) are taken from the GTK |
235 | theme when Emacs is built with GTK. | |
236 | ||
aa1859f5 J |
237 | ** Emacs uses GTK tooltips by default if built with GTK. You can turn that |
238 | off by customizing x-gtk-use-system-tooltips. | |
239 | ||
1ecb2d3f | 240 | ** Lucid menus and dialogs can display antialiased fonts if Emacs is built |
3928f2b6 JD |
241 | with Xft. To change font, use the X resource font, for example: |
242 | Emacs.pane.menubar.font: Courier-12 | |
99852628 | 243 | |
917794d5 | 244 | ** On graphical displays, the mode-line no longer ends in dashes. |
1dd3c2d9 CY |
245 | Also, the first dash (which does not indicate anything) is just |
246 | displayed as a space. | |
917794d5 | 247 | |
5ffb62aa | 248 | ** On Nextstep/OSX, the menu bar can be hidden by customizing |
f042970d | 249 | ns-auto-hide-menu-bar. |
5ffb62aa | 250 | |
b7d65a5f GM |
251 | ** Basic SELinux support has been added. |
252 | This requires Emacs to be linked with libselinux at build time. | |
253 | ||
d8004abe GM |
254 | *** Emacs preserves the SELinux file context when backing up, and |
255 | optionally when copying files. To this end, copy-file has an extra | |
256 | optional argument, and backup-buffer and friends include the SELinux | |
257 | context in their return values. | |
b7d65a5f GM |
258 | |
259 | *** The new functions file-selinux-context and set-file-selinux-context | |
260 | get and set the SELinux context of a file. | |
261 | ||
a5bee597 MA |
262 | *** Tramp offers handlers for file-selinux-context and set-file-selinux-context |
263 | for remote machines which support SELinux. | |
264 | ||
a4180391 PE |
265 | +++ |
266 | ** The function format-time-string now supports the %N directive, for | |
267 | higher-resolution time stamps. | |
268 | ||
9c524fcb | 269 | ** The function kill-emacs is now run upon receipt of the signals SIGTERM |
383ebd15 | 270 | and SIGHUP, and upon SIGINT in batch mode. |
9c524fcb GM |
271 | |
272 | ** kill-emacs-hook is now also run in batch mode. | |
63c72eeb GM |
273 | If you have code that adds something to kill-emacs-hook, you should |
274 | consider if it is still appropriate to add it in the noninteractive case. | |
9c524fcb | 275 | |
79ce172a | 276 | ** New scrolling commands `scroll-up-command' and `scroll-down-command' |
0a19a6f8 JB |
277 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
278 | of buffer at first key-press (instead move to top/bottom of buffer) | |
7b05466f | 279 | when a new variable `scroll-error-top-bottom' is non-nil. |
79ce172a | 280 | |
5a97d2da JL |
281 | ** New scrolling commands `scroll-up-line' and `scroll-down-line' |
282 | scroll a line instead of full screen. | |
283 | ||
a4b000fb | 284 | ** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 285 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
9013a7f8 | 286 | |
d0f69533 EZ |
287 | +++ |
288 | ** If you customize `scroll-conservatively' to a value greater than 100, | |
289 | Emacs will never recenter point in the window when it scrolls due to | |
290 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | |
291 | Previously, you needed to use `most-positive-fixnum' as the value of | |
292 | `scroll-conservatively' to achieve the same effect. | |
293 | ||
294 | --- | |
295 | ** ``Aggressive'' scrolling now honors the scroll margins. | |
296 | If you customize `scroll-up-aggressively' or | |
297 | `scroll-down-aggressively' and move point off the window, Emacs now | |
298 | scrolls the window so as to avoid positioning point inside the scroll | |
299 | margin. | |
300 | ||
f1a5d776 CY |
301 | ** Trash changes |
302 | ||
303 | *** `delete-by-moving-to-trash' now only affects commands that specify | |
304 | trashing. This avoids inadvertently trashing temporary files. | |
305 | ||
306 | *** Calling `delete-file' or `delete-directory' with a prefix argument | |
307 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
308 | ||
f0bf7c8e JL |
309 | ** New option `list-colors-sort' defines the color sort order |
310 | for `list-colors-display'. | |
311 | ||
44198b6e CY |
312 | ** An Emacs Lisp package manager is now included. |
313 | This is a convenient way to download and install additional packages, | |
42d9cffa | 314 | from a package repository at elpa.gnu.org. |
cb6c4991 CY |
315 | |
316 | *** `M-x list-packages' shows a list of packages, which can be | |
317 | selected for installation. | |
318 | ||
319 | *** New command `describe-package', bound to `C-h P'. | |
44198b6e CY |
320 | |
321 | *** By default, all installed packages are loaded and activated | |
322 | automatically when Emacs starts up. To disable this, set | |
323 | `package-enable-at-startup' to nil. To change which packages are | |
324 | loaded, customize `package-load-list'. | |
325 | ||
d221e780 CO |
326 | ** An Emacs Lisp testing tool is now included. |

330 | ** Custom Themes |
331 | ||
332 | *** `M-x customize-themes' lists Custom themes which can be enabled. | |
333 | ||
782b5e8d CY |
334 | *** New option `custom-theme-load-path' is the load path for themes. |
335 | Emacs no longer looks for custom themes in `load-path'. The default | |
336 | is to search in `custom-theme-directory', followed by a built-in theme | |
337 | directory named "themes/" in `data-directory'. | |
338 | ||
b7617f6d CY |
339 | *** New option `custom-safe-themes' records known-safe theme files. |
340 | If a theme is not in this list, Emacs queries before loading it, and | |
341 | offers to save the theme to `custom-safe-themes' automatically. By | |
342 | default, all themes included in Emacs are treated as safe. | |

388 | ** There is a new command `count-words-region', which does what you expect. | |
389 | ||
67027b49 | 390 | ** completion-at-point now handles tags and semantic completion. |
a982c7ec | 391 | |

392 | ** The default value of `backup-by-copying-when-mismatch' is now t. |
393 | ||
1c708c1a CY |
394 | ** The command `just-one-space' (C-SPC), if given a negative argument, |
395 | also deletes newlines around point. | |
396 | ||
b9229673 CY |
397 | ** Deletion changes |
398 | ||
399 | *** New option `delete-active-region'. | |
400 | If non-nil, C-d, [delete], and DEL delete the region if it is active | |
401 | and no prefix argument is given. If set to `kill', these commands | |
402 | kill instead. | |
403 | ||
404 | *** New command `delete-forward-char', bound to C-d and [delete]. | |
42d9cffa CY |
405 | This is meant for interactive use, and obeys `delete-active-region'. |
406 | The command `delete-char' does not obey `delete-active-region'. | |
b9229673 CY |
407 | |
408 | *** `delete-backward-char' is now a Lisp function. | |
409 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
410 | However, the byte compiler now warns if it is called from Lisp; you | |
411 | should use delete-char with a negative argument instead. | |
412 | ||
413 | *** The option `mouse-region-delete-keys' has been deleted. | |
414 | ||
f9d71b42 CY |
415 | ** Selection changes. |
416 | ||
b1ab31ae CY |
417 | The default handling of clipboard and primary selections was changed |
418 | to conform with modern X applications. In short, most commands for | |
419 | killing and yanking text now use the clipboard, while mouse commands | |
420 | use the primary selection. | |
421 | ||
422 | In the following, we provide a list of these changes, followed by a | |
423 | list of steps to get the old behavior back if you prefer that. | |
424 | ||
963578d3 | 425 | +++ |
b1ab31ae CY |
426 | *** `select-active-regions' now defaults to t. |
427 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | |
963578d3 | 428 | the kill ring. The selected text is put in the primary selection, if |
b1ab31ae CY |
429 | the system possesses a separate primary selection facility (e.g. X). |
430 | ||
963578d3 | 431 | +++ |
b1ab31ae CY |
432 | **** `select-active-regions' also accepts a new value, `only'. |
433 | This means to only set the primary selection for temporarily active | |
434 | regions (usually made by mouse-dragging or shift-selection); | |
435 | "ordinary" active regions, such as those made with C-SPC followed by | |
436 | point motion, do not alter the primary selection. | |
437 | ||
963578d3 CY |
438 | --- |
439 | **** `mouse-drag-copy-region' now defaults to nil. | |
440 | ||
441 | +++ | |
b1ab31ae CY |
442 | *** mouse-2 is now bound to `mouse-yank-primary'. |
443 | This pastes from the primary selection, ignoring the kill-ring. | |
444 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | |
445 | ||
963578d3 | 446 | +++ |
b1ab31ae | 447 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
963578d3 | 448 | +++ |
b1ab31ae CY |
449 | *** `x-select-enable-primary' now defaults to nil. |
450 | Thus, commands that kill text or copy it to the kill-ring (such as | |
451 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | |
452 | ||
963578d3 | 453 | --- |
b1ab31ae CY |
454 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now |
455 | exactly equivalent to, respectively M-w, C-w, and C-y. | |
456 | ||
963578d3 | 457 | --- |
b1ab31ae CY |
458 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already |
459 | non-nil by default, as Windows does not support the primary selection | |
460 | between applications. | |
461 | ||
963578d3 | 462 | --- |
b1ab31ae | 463 | *** To return to the previous behavior, do the following: |
104c2fe9 | 464 | **** Change `select-active-regions' to nil. |
b1ab31ae CY |
465 | **** Change `mouse-drag-copy-region' to t. |
466 | **** Change `x-select-enable-primary' to t (on X only). | |
467 | **** Change `x-select-enable-clipboard' to nil. | |
468 | **** Bind `mouse-yank-at-click' to mouse-2. | |
f9d71b42 | 469 | |

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

1dd3c2d9 CY |
473 | *** Support for X clipboard managers has been added. |
474 | ||
4b80f674 CY |
475 | **** To inhibit use of the clipboard manager, set |
476 | `x-select-enable-clipboard-manager' to nil. | |
477 | ||
99f053cf JA |
478 | ** New command `rectangle-number-lines', bound to `C-x r N', numbers |
479 | the lines in the current rectangle. With an prefix argument, this | |
480 | prompts for a number to count from and for a format string. | |
481 | ||
70436396 MA |
482 | ** The command shell prompts for the shell path name, when the default |
483 | directory is a remote file name and neither environment variable | |
484 | $ESHELL nor variable `explicit-shell-file-name' is set. | |

7deebf1b LMI |
537 | ** `url-queue-retrieve' downloads web pages asynchronously, but allow |
538 | controlling the degree of parallelism. | |
539 | ||
817b48a7 GM |
540 | ** Directory local variables can apply to file-less buffers, in certain modes |
541 | (eg dired, vc-dir, log-edit). For example, adding | |
542 | "(diff-mode . ((mode . whitespace)))" to your .dir-locals.el file, | |
543 | will turn on `whitespace-mode' for *vc-diff* buffers. Modes should | |
544 | call `hack-dir-local-variables-non-file-buffer' to support this. | |
545 | ||
6640b281 GM |
546 | +++ |
547 | ** You can prevent directory local variables from applying to subdirectories. | |
548 | Add an element (subdirs . nil) to the alist portion of any variables | |
549 | settings to indicate said section should not be applied to subdirectories. | |
550 | ||
8a8d54cd VD |
551 | ** ERC changes |
552 | ||
553 | *** New vars `erc-autojoin-timing' and `erc-autojoin-delay'. | |
554 | If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a | |
555 | successful NickServ identification, or after `erc-autojoin-delay' | |
556 | seconds. The default value, 'ident, means to autojoin immediately | |
557 | after connecting. | |
558 | ||
5c0c0f77 LMI |
559 | *** New variable `erc-coding-system-precedence': If we use `undecided' |
560 | as the server coding system, this variable will then be consulted. | |
561 | The default is to decode strings that can be decoded as utf-8 as | |
562 | utf-8, and do the normal `undecided' decoding for the rest. | |
563 | ||
c0e505e5 CY |
564 | ** Eshell changes |
565 | ||
566 | *** The default value of eshell-directory-name is a directory named | |

cf16af42 GM |
604 | --- |
605 | *** The obsolete (since Emacs 22.1) method of enabling the appt package | |
606 | by adding appt-make-list to diary-hook has been removed. Use appt-activate. | |
607 | ||
608 | --- | |
609 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: | |
610 | appt-issue-message (use the function appt-activate) | |
611 | appt-visible/appt-msg-window (use the variable appt-display-format) | |
612 | ||

614 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: | |
615 | view-diary-entries, list-diary-entries, show-all-diary-entries | |
616 | ||
52834b6b CY |
617 | ** Customize |
618 | ||
619 | *** Customize buffers now contain a search field. | |
620 | The search is performed using `customize-apropos'. | |
42d9cffa | 621 | To turn off the search field, set custom-search-field to nil. |
52834b6b CY |

623 | *** Custom options now start out hidden if at their default values. | |
624 | Use the arrow to the left of the option name to toggle visibility. | |
625 | ||
626 | *** custom-buffer-sort-alphabetically now defaults to t. | |
627 | ||
628 | *** The color widget now has a "Choose" button, which allows you to | |
629 | choose a color via list-colors-display. | |
630 | ||
f5d6548a JL |
631 | ** Dired-x |
632 | ||
633 | *** dired-jump and dired-jump-other-window called with a prefix argument | |
634 | read a file name from the minibuffer instead of using buffer-file-name. | |
635 | ||
817b48a7 GM |

8117868f | 639 | |
7492acc9 MM |
640 | ** SQL Mode enhancements. |
641 | ||
9250002f MM |
642 | *** `sql-dialect' is a synonym for `sql-product'. |
643 | ||
74790210 | 644 | *** Added ability to login with a port on MySQL and Postgres. |
7492acc9 | 645 | The custom variable `sql-port' can be specified for connection to |
74790210 MM |
646 | MySQL or Postgres servers. By default, the port is not listed in |
647 | either login parameter, but will be added to the command line if set | |
648 | to a non-zero value. | |
7492acc9 | 649 | |
9250002f MM |
650 | *** Dynamic selection of product in an SQL interactive session. |
651 | If you use `sql-product-interactive' to start an SQL interactive | |
652 | session it uses the current value of `sql-product'. Preceding the | |
653 | invocation with C-u will force it to ask for the product before | |
654 | creating the session. | |
655 | ||
656 | *** Renaming a SQL interactive buffer when it is created. | |
657 | Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres', | |
658 | `sql-mysql', etc.) with C-u will force a new interactive session to be | |
659 | started and will prompt for the new name. This will reduce the need | |
660 | for `sql-rename-buffer' is most common use cases. | |
661 | ||
3bd2cfef MM |
662 | *** Command continuation prompts in SQL interactive mode are suppressed. |
663 | Multiple line commands in SQL interactive mode, generate command | |
664 | continuation prompts which needlessly confuse the output. These | |
665 | prompts are now filtered out from the output. This change impacts | |
666 | multiple line SQL statements entered with C-j between each line, | |
667 | statements yanked into the buffer and statements sent with | |
668 | `sql-send-*' functions. | |
669 | ||
7492acc9 MM |
670 | *** Custom variables control prompting for login parameters. |
671 | Each supported product has a custom variable `sql-*-login-params' | |
672 | which is a list of the parameters to be prompted for before a | |
673 | connection is established. | |
674 | ||
74790210 MM |
675 | The lists consist of the following five tokens: `user', `password', |
676 | `database', `server', and `port'. The order in which they appear is | |
677 | the order in which they are prompted. The tokens symbols can be | |
678 | replaced by a sublist starting with the token and followed by a plist | |
679 | which control the prompting for values. The tokens `user', | |
680 | `database', and `server' each can take a property of :default which | |
681 | specifies the value to be used if no value is entered. The | |
682 | `database', `server', and `port' tokens handle the :completion | |
683 | property which restricts the entry to either one of the values in the | |
684 | list or to one of the values returned by the function provided as the | |
685 | property value. The `database' and `server' tokens also accept the | |
686 | :file property whose value is a regexp to identify useful file names. | |
687 | ||
688 | (user :default DEF) | |
689 | (database :default DEF | |
690 | :file FILEPAT | |
691 | :completion COMPLETE) | |
692 | (server :default DEF | |
693 | :file FILEPAT | |
694 | :completion COMPLETE) | |
695 | ||
696 | The FILEPAT when :file is specified is a regexp that will match valid | |
697 | file names (without the directory portion). Generally these strings | |
698 | will be of the form ".+\.SUF" where SUF is the desired file suffix. | |
699 | ||
700 | When :completion is specified, the COMPLETE corresponds to the | |
701 | PREDICATE argument to the `completing-read' function (a list of | |
702 | possible values or a function returning such a list). | |
5474c40f | 703 | |
30c4d8dc MM |
704 | *** Added `sql-connection-alist' to record login parameter values. |
705 | An alist for recording different username, database and server | |
706 | values. If there are multiple databases that you connect to the | |
707 | parameters needed can be stored in this alist. | |
708 | ||
709 | For example, the following might be set in the user's init.el: | |
710 | ||
711 | (setq sql-connection-alist | |
712 | '((dev (sql-product 'sqlite) | |
713 | (sql-database "/home/mmaug/dev.db")) | |
714 | (prd (sql-product 'oracle) | |
715 | (sql-user "mmaug") | |
716 | (sql-database "iprd2a")))) | |
717 | ||
718 | This defines two connections named "dev" and "prd". | |
719 | ||
720 | *** Added `sql-connect' to use predefined connections. | |
721 | Sets the login parameters based on the values in the | |
722 | `sql-connection-alist' and start a SQL interactive session. Any | |
723 | values specified in the connection will not be prompted for. | |
724 | ||
725 | In the example above, if the user were to invoke M-x sql-connect, they | |
726 | would be prompted for the connection. The user can respond with | |
727 | either "dev" or "prd". The "dev" connection would connect to the | |
728 | SQLite database without prompting; the "prd" connection would prompt | |
729 | for the users password and then connect to the Oracle database. | |
730 | ||
d26b0ea9 | 731 | **** Added SQL->Start... submenu when connections are defined. |
b2957ea8 | 732 | When connections have been defined, there is a submenu available that |
d26b0ea9 MM |
733 | allows the user to select one to start a SQLi session. The "Start |
734 | SQLi Session" item moves to the "Start..." submenu when cnnections | |
735 | have been defined. | |
736 | ||
737 | **** Added "Save Connection" menu item in SQLi buffers. | |
738 | When a SQLi session is not started by a connection then | |
739 | `sql-save-connection' will gather the login params specified for the | |
740 | session and save them as a new connection. | |
741 | ||
74790210 MM |
742 | *** List database objects and details. |
743 | Once a SQL interactive session has been started, you can get a list of | |
744 | the objects in the database and see details of those objects. The | |
745 | objects shown and the details available are product specific. | |
746 | ||
747 | **** List all objects. | |
748 | Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all | |
749 | objects" will list all the objects in the database. At a minimum it | |
86485587 | 750 | lists the tables and views in the database. Preceding the command by |
74790210 MM |
751 | universal argument may provide additional details or extend the |
752 | listing to include other schemas objects. The list will appear in a | |
753 | separate window in view-mode. | |
754 | ||
755 | **** List Table details. | |
756 | Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table | |
757 | details" will ask for the name of a database table or view and display | |
86485587 | 758 | the list of columns in the relation. Preceding the command with the |
74790210 MM |
759 | universal argument may provide additional details about each column. |
760 | The list will appear in a separate window in view-mode. | |
761 | ||
7492acc9 MM |
762 | *** Added option `sql-send-terminator'. |
763 | When set makes sure that each command sent with `sql-send-*' commands | |
764 | are properly terminated and submitted to the SQL processor. | |
765 | ||
766 | *** Added option `sql-oracle-scan-on'. | |

914 | --- |
915 | ** `char-direction-table' and the associated function `char-direction' | |
916 | were deleted. They were buggy and inferior to the new support of | |
917 | bidirectional editing introduced in Emacs 24. If you need the | |
918 | bidirectional properties of a character, use `get-char-code-property' | |
919 | with the last argument `bidi-class'. | |
920 | ||
470d996d TV |
921 | ** `copy-directory' now copies the source directory as a subdirectory |
922 | of the target directory, if the latter is an existing directory. The | |
923 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy | |
924 | the contents directly into a pre-existing target directory. | |
925 | ||
25ca2e61 CY |
926 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
927 | passes it to the mail user agent function. This argument specifies an | |
928 | action for returning to the caller after finishing with the mail. | |
929 | This is currently used by Rmail to delete a mail window. | |

931 | ** For mouse click input events in the text area, the Y pixel |
932 | coordinate in the POSITION list now counts from the top of the text | |

998 | - :exit-function, function to call after completion took place. | |

620c53a6 SM |
1005 | *** New `metadata' method for completion tables. The metadata thus returned |
1006 | can specify various details of the data returned by `all-completions': | |
1007 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | |
1008 | used to select a style in completion-category-overrides. | |
1009 | - `annotation-function' to add annotations in *Completions*. | |
1010 | - `display-sort-function' to specify how to sort entries in *Completions*. | |
1011 | - `cycle-sort-function' to specify how to sort entries when cycling. | |

da91b5f2 CY |
1016 | ** `open-network-stream' can now be used to open an encrypted stream. |
1017 | It now accepts an optional `:type' parameter for initiating a TLS | |
1018 | connection, directly or via STARTTLS. To do STARTTLS, additional | |
1019 | parameters (`:end-of-command', `:success', `:capabilities-command') | |
1020 | must also be supplied. | |

03408648 SM |
1022 | ** Code can now use lexical scoping by default instead of dynamic scoping. |
1023 | The `lexical-binding' variable lets code use lexical scoping for local | |
1024 | variables. It is typically set via file-local variables, in which case it | |
1025 | applies to all the code in that file. | |
1026 | ||
1027 | *** `eval' takes a new optional argument `lexical' to choose the new lexical | |

cf38dd42 SM |
1064 | ** New variable syntax-propertize-function to set syntax-table properties. |
1065 | Replaces font-lock-syntactic-keywords which are now obsolete. | |
1066 | This allows syntax-table properties to be set independently from font-lock: | |
1067 | just call syntax-propertize to make sure the text is propertized. | |
1068 | Together with this new variable come a new hook | |
1069 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
1070 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |

1125 | in gnutls.el, namely the `open-gnutls-stream' and `gnutls-negotiate' | |
1126 | functions. It's easiest to use these functions through | |
1127 | `open-network-stream' because it can upgrade connections through | |
1128 | STARTTLS opportunistically or use plain SSL, depending on your needs. | |

1141 | ** Progress reporters can now "spin". |
1142 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
1143 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
1144 | time you call `progress-reporter-update' on that progress reporter, | |
1145 | with a nil or omitted VALUE argument, the reporter message is | |
1146 | displayed with a "spinning bar". | |

1148 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is |
1149 | being reverted, even if the buffer has a local `revert-buffer-function'. | |
1150 | ||
638f053a JB |
1151 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook' allow |
1152 | deferring warnings until the main command loop is executed. | |

1156 | as well as those in the -*- line. | |
