24 * Installation Changes in Emacs 24.2
25
26 ** New configure option '--enable-gcc-warnings', intended for developers.
27 If building with GCC, this enables compile-time checks that warn about
28 possibly-questionable C code. On a recent GNU system there should be
29 no warnings; on older and on non-GNU systems the generated warnings
30 may be useful.
31
32 ** The configure option '--disable-maintainer-mode' has been removed,
33 as it was confusingly-named and rarely useful.
34
35 ---
36 ** Emacs uses libtinfo in preference to libncurses, if available.
37
38 ---
39 ** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and
40 /usr/pkg/lib to the linker search path. You must add them yourself if
41 you want them.
42
43 ---
44 ** On Mac OS X, configure no longer automatically adds the Fink /sw
45 directories to the search path. You must add them yourself if you want them.
46
47 ---
48 ** The standalone scripts rcs-checkin and vcdiff have been removed
49 (from the bin and libexec directories, respectively). The former is
50 no longer relevant, the latter is replaced by lisp (in vc-sccs.el).
51
52 ** The configuration option '--enable-use-lisp-union-type' has been
53 renamed to '--enable-check-lisp-object-type', as the resulting
54 Lisp_Object type no longer uses a union to implement the compile time
55 check that this option enables.
56
57 \f
58 * Startup Changes in Emacs 24.2
59
60 ** Emacs no longer searches for `leim-list.el' files beneath the standard
61 lisp/ directory. There should not be any there anyway. If you have
62 been adding them there, put them somewhere else, eg site-lisp.
63
64 \f
65 * Changes in Emacs 24.2
66
67 ** New functions `system-users', `system-groups' return lists of the user
68 name, group names known to the system (where possible).
69
70 ** If your Emacs was built from a bzr checkout, the new variable
71 `emacs-bzr-version' contains information about which bzr revision was used.
72
73 ** ImageMagick support, if available, is automatically enabled.
74 It is no longer necessary to call `imagemagick-register-types'
75 explicitly to install ImageMagick image types; that function is called
76 automatically at startup, or when customizing a relevant imagemagick-
77 option.
78
79 *** Setting `imagemagick-types-inhibit' to t now disables the use of
80 ImageMagick to view images. You must call imagemagick-register-types
81 afterwards if you do not use customize to change this.
82
83 *** The new variable `imagemagick-enabled-types' also affects which
84 ImageMagick types are treated as images. The function
85 `imagemagick-filter-types' returns the list of types that will be
86 treated as images.
87
88 *** Images displayed via ImageMagick now support transparency and the
89 :background image spec property.
90
91 ** String values for `initial-buffer-choice' also apply to emacsclient
92 frames, if emacsclient is only told to open a new frame without
93 specifying any file to visit or expression to evaluate.
94
95 +++
96 ** You can prevent the creation of lock files by setting `create-lockfiles'
97 to nil. Use with caution, and only if you really need to.
98
99 +++
100 ** Using "unibyte: t" in Lisp source files is obsolete.
101 Use "coding: raw-text" instead.
102
103 ** Mode line changes
104
105 *** New option `mode-line-default-help-echo' specifies the help text
106 (shown in a tooltip or in the echo area) for any part of the mode line
107 that does not have its own specialized help text.
108
109 *** You can now click mouse-3 in the coding system indicator to
110 invokes `set-buffer-file-coding-system'.
111
112 +++
113 ** Setting `enable-remote-dir-locals' to non-nil allows directory
114 local variables on remote hosts.
115
116 \f
117 * Editing Changes in Emacs 24.2
118
119 ** Search changes
120
121 *** Global `M-s _' starts a symbol (identifier) incremental search,
122 and `M-s _' in Isearch toggles symbol search mode.
123 `M-s c' in Isearch toggles search case-sensitivity.
124
125 ** M-x move-to-column, if called interactively with no prefix arg, now
126 prompts for a column number.
127
128 ** `mouse-avoidance-banish-position' can now be used to customize
129 `mouse-avoidance-mode' further.
130
131 ** `C-M-f' and `C-M-b' will now move to the path name separator
132 character when doing minibuffer filename prompts.
133
134 ** `goto-char' is now bound to `M-g c'.
135
136 ** New input method `vietnamese-vni'.
137
138 \f
139 * Changes in Specialized Modes and Packages in Emacs 24.2
140
141 ** CL's main entry is now (require 'cl-lib).
142 `cl-lib' is like the old `cl' except that it uses the namespace cleanly,
143 i.e. all its definitions have the "cl-" prefix.
144
145 If `cl' provided a feature under the name `foo', then `cl-lib' provides it
146 under the name `cl-foo' instead, with the exceptions of the few definitions
147 that had to use `foo*' to avoid conflicts with pre-existing Elisp entities,
148 which have not been renamed to `cl-foo*' but just `cl-foo'.
149
150 The old `cl' is now deprecated and is nothing more than a bunch of aliases that
151 provide the old non-prefixed names.
152
153 ** VHDL-mode
154 - Support for ghdl (free vhdl compiler). Now default.
155 - Add/update support for VHDL-AMS packages.
156 - Update to VHDL'02 standard.
157 - Accept \r and \f as whitespace.
158
159 ** Diff mode
160
161 Faces for changes now use the same diff color scheme as in modern VCSes
162 where deletions are displayed in red (new faces `diff-refine-removed'
163 and `smerge-refined-removed' and new definition of `diff-removed'),
164 insertions in green (new faces `diff-refine-added' and
165 `smerge-refined-added' and new definition of `diff-added').
166 The variable `diff-use-changed-face' defines whether to use
167 the face `diff-changed', or `diff-removed' and `diff-added'
168 to highlight changes in context diffs.
169
170 ** Ediff now uses the same color scheme as Diff mode
171 on high color displays.
172
173 ** `sh-script'
174 *** Pairing of parens/quotes uses electric-pair-mode instead of skeleton-pair.
175 *** `sh-electric-here-document-mode' now controls auto-insertion of here-docs.
176 *** `sh-use-smie' lets you choose a new indentation and navigation code.
177
178 ** reStructuredText mode
179
180 *** Rebind nearly all keys making room for more keys and complying
181 better to usage in other modes. Describe bindings with C-c C-h.
182
183 *** Major revision of indentation working very similar to other
184 modes. TAB is your friend.
185
186 *** Major revision of filling working fine with most of
187 reStructuredText syntax. Support auto-filling.
188
189 *** Major revision of comment handling.
190
191 *** Major revision of fontification working with `jit-lock-mode'.
192
193 *** Cover reStructuredText syntax more closely. Improve
194 the experience for Sphinx users.
195
196 *** `rst-insert-list' inserts new list or continues existing lists.
197
198 *** Extend correct and improve customization.
199
200 *** Negative prefix argument always works for `rst-adjust'.
201
202 *** Reset window configuration after displaying TOC.
203
204 *** Package version in `rst-version'.
205
206 ** New `derived-mode' filter for Ibuffer, bound to `/ M'.
207 `/ m' is now bound to filter by used-mode, which used to be bound to `/ M'.
208
209 ** Apropos
210
211 *** The faces used by Apropos are now directly customizable.
212 These faces are named `apropos-symbol', `apropos-keybinding', and so on;
213 see the `apropos' Custom group for details.
214
215 **** The old options whose values specified faces to use were removed
216 (i.e. `apropos-symbol-face', `apropos-keybinding-face', etc.).
217
218 ** Buffer Menu
219 This package has been rewritten to use Tabulated List mode.
220
221 *** Option `Buffer-menu-buffer+size-width' is now obsolete.
222 Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead.
223
224 ** Calendar
225
226 *** The calendars produced by cal-html include holidays.
227 Customize cal-html-holidays to change this.
228
229 ** Customize
230
231 *** `custom-reset-button-menu' now defaults to t.
232
233 *** Non-option variables are never matched in `customize-apropos' and
234 `customize-apropos-options' (i.e. the prefix argument does nothing for
235 these commands now).
236
237 ** erc will look up server/channel names via auth-source and use the
238 channel keys found, if any.
239
240 ** FFAP
241
242 *** The option `ffap-url-unwrap-remote' can now be a list of strings,
243 specifying URL types which should be converted to remote file names at
244 the FFAP prompt. The default is now '("ftp").
245
246 ** Follow mode
247
248 *** The obsolete variable `follow-mode-off-hook' has been removed.
249
250 *** Follow mode no longer works by using advice.
251 The option `follow-intercept-processes' has been removed.
252
253 ** The `server-auth-key' variable can be used to set a permanent
254 shared key for Emacs Server.
255
256 ** In Perl mode, new option `perl-indent-parens-as-block' causes non-block
257 closing brackets to be aligned with the line of the opening bracket.
258
259 ** FIXME something happened to ses.el, 2012-04-17.
260
261 ** which-function-mode now applies to all applicable major modes by default.
262
263 ** Tramp
264
265 +++
266 *** The syntax has been extended in order to allow ad-hoc proxy
267 definitions. See the manual for details.
268
269 +++
270 *** Remote processes are now supported also on remote Windows host.
271
272 ** D-Bus
273
274 +++
275 *** New variables `dbus-compiled-version' and `dbus-runtime-version'.
276
277 +++
278 *** The D-Bus object manager interface is implemented.
279
280 +++
281 *** Variables of type :(u)int32 and :(u)int64 accept floating points,
282 if their value does not fit into Emacs's integer range.
283
284 +++
285 *** The function `dbus-call-method' works non-blocking now, it can be
286 interrupted by C-g. `dbus-call-method-non-blocking' is obsolete.
287
288 +++
289 *** Signals can be sent also as unicast message.
290
291 +++
292 *** The argument list of `dbus-register-signal' has been extended,
293 according to the new match rule types of D-Bus. See the manual for
294 details.
295
296 +++
297 *** `dbus-init-bus' supports private connections.
298
299 +++
300 *** There is a new function `dbus-setenv'.
301
302 +++
303 ** notifications.el supports now version 1.2 of the Notifications API.
304 The function `notifications-get-capabilities' returns the supported
305 server properties.
306
307 ** Package Menu
308
309 *** Newly-available packages are listed in the Package Menu as "new",
310 and sorted above the other "available" packages by default.
311
312 ** Tabulated List and packages derived from it
313
314 *** New command `tabulated-list-sort', bound to `S', sorts the column
315 at point, or the Nth column if a numeric prefix argument is given.
316
317 ** URL
318
319 *** Structs made by `url-generic-parse-url' have nil `attributes' slot.
320 Previously, this slot stored semicolon-separated attribute-value pairs
321 appended to some imap URLs, but this is not compatible with RFC 3986.
322 So now the `filename' slot stores the entire path and query components
323 and the `attributes' slot is always nil.
324
325 *** New function `url-encode-url' for encoding a URI string.
326 The `url-retrieve' function now uses this to encode its URL argument,
327 in case that is not properly encoded.
328
329 ** Obsolete packages:
330
331 *** assoc.el
332 In most cases, assoc+member+push+delq work just as well.
333 And in any case it's just a terrible package: ugly semantics, terrible
334 inefficiency, and not namespace-clean.
335
336 *** bruce.el
337
338 *** ledit.el
339
340 *** mailpost.el
341
342 *** mouse-sel.el
343
344 *** patcomp.el
345
346 *** cust-print.el
347
348 \f
349 * New Modes and Packages in Emacs 24.2
350 \f
351 * Incompatible Lisp Changes in Emacs 24.2
352
353 +++
354 ** Docstrings starting with `*' no longer indicate user options.
355 Only variables defined using `defcustom' are considered user options.
356 The function `user-variable-p' is now an obsolete alias for
357 `custom-variable-p'.
358
359 ** `face-spec-set' no longer sets frame-specific attributes when the
360 third argument is a frame (that usage was obsolete since Emacs 22.2).
361
362 +++
363 ** The arguments of `dbus-register-signal' are no longer just strings,
364 but keywords or keyword-string pairs. The old argument list will
365 still be supported for Emacs 24.x.
366
367 ** The following obsolete variables and varaliases have been removed:
368
369 *** `facemenu-unlisted-faces'
370 *** `rmail-decode-mime-charset'
371
372 \f
373 * Lisp changes in Emacs 24.2
374
375 ** `defun' also accepts a (declare DECLS) form, like `defmacro'.
376 The interpretation of the DECLS is determined by `defun-declarations-alist'.
377
378 ** `macro-declaration-function' is obsolete, use `macro-declarations-alist'.
379
380 ** New function `set-temporary-overlay-map'.
381
382 ** New macros `setq-local' and `defvar-local'.
383
384 ** New error type and new function `user-error'. Doesn't trigger the debugger.
385
386 ** The functions get-lru-window, get-mru-window and get-largest-window
387 now accept a third argument to avoid chosing the selected window.
388
389 ** Completion
390
391 *** New function `completion-table-with-quoting' to handle completion
392 in the presence of quoting, such as file completion in shell buffers.
393
394 *** New function `completion-table-subvert' to use an existing completion
395 table, but with a different prefix.
396
397 ** Time
398
399 *** `current-time-string' no longer requires that its argument's year
400 must be in the range 1000..9999. It now works with any year supported
401 by the underlying C implementation.
402
403 ** `automount-dir-prefix' is obsolete.
404 ** `buffer-has-markers-at' is obsolete.
405 \f
406 * Changes in Emacs 24.2 on non-free operating systems
407
408 ** New configure.bat options on MS-Windows:
409
410 *** --without-libxml2 omits support for libxml2, even if its presence
411 is detected.
412
413 ** When invoked with the -nw switch to run on the Windows text-mode terminal,
414 Emacs now supports mouse highlight, help-echo (in the echo area), and
415 mouse-autoselect-window.
416
417 \f
418 * Installation Changes in Emacs 24.1
419
420 ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
421 to configure. Note that other libraries used by Emacs, RSVG and GConf,
422 also depend on Gtk+. You can disable them with --without-rsvg and
423 --without-gconf.
424
425 ** Emacs can be compiled with GnuTLS support.
426 This happens by default if a suitably recent version of the library is
427 found at build time. To prevent this, use the configure option
428 `--without-gnutls'. See below for GnuTLS features.
429
430 ** Emacs can be compiled with SELinux support.
431 This happens by default if a suitably recent version of the library is
432 found at build time. To prevent this, use the configure option
433 `--without-selinux'. See below for SELinux features.
434
435 ** Emacs can be compiled with ImageMagick support.
436 This happens by default if a suitably recent version of the library is
437 found at build time. To prevent this, use the configure option
438 `--without-imagemagick'. See below for ImageMagick features.
439 This feature is not available for the Nextstep or MS ports.
440
441 ** Emacs can be compiled with libxml2 support.
442 This happens by default if a suitably recent version of the library is
443 found at build time. To prevent this, use the configure option
444 `--without-xml2'. See below for libxml2 features.
445
446 ** By default, the installed Info and man pages are compressed.
447 You can disable this by configuring --without-compress-info.
448
449 ** New configure option --with-wide-int.
450 With it, Emacs integers typically have 62 bits, even on 32-bit machines.
451 On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB
452 to about 2 GiB.
453
454 ** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost.
455 These provide no new functionality, they just remove the need to edit
456 lib-src/Makefile by hand in order to use the associated features.
457
458 ** New configure option --enable-use-lisp-union-type.
459 This is only useful for Emacs developers to debug certain types of bugs.
460 This is not a new feature; only the configure flag is new.
461
462 ** The standalone programs digest-doc and sorted-doc are removed.
463 Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'.
464
465 ** The standalone program `fakemail' is removed.
466 If you need it, feedmail.el provides a superset of the functionality.
467
468 \f
469 * Startup Changes in Emacs 24.1
470
471 ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
472 command line arguments, and the EMACS_UNIBYTE environment variable, no
473 longer have any effect. (They were declared obsolete in Emacs 23.)
474
475 ** New command line option `--no-site-lisp' removes site-lisp directories
476 from load-path. -Q now implies this. This option does not affect the
477 EMACSLOADPATH environment variable (and hence has no effect for
478 Nextstep builds).
479
480 \f
481 * Changes in Emacs 24.1
482
483 ** Completion
484
485 *** Many packages now use the `completion-at-point' command,
486 rather than implementing separate completion commands.
487
488 *** `completion-at-point' now handles tags and semantic completion.
489
490 *** Completion in a non-minibuffer now tries to detect the end of completion
491 and pops down the *Completions* buffer accordingly.
492
493 *** New option `completion-cycle-threshold' allows completion cycling.
494
495 *** New option `completion-category-overrides' for overriding the
496 default completion style in certain circumstances.
497
498 *** New completion style `substring'.
499
500 *** Completion of buffer names uses `substring' completion by default.
501
502 *** The option `widget-complete-field' has been removed.
503
504 ** Mail changes
505
506 *** The first time you try sending mail, Emacs asks for a mail method.
507 This is implemented by a new default for `send-mail-function', which
508 is `sendmail-query-once'. This offers to use the smtpmail package, or
509 to use the old defaults relying on external mail facilities
510 (`sendmail-send-it' on GNU/Linux and other Unix-like systems, and
511 `mailclient-send-it' on Windows).
512
513 *** Typing C-c m in the buffer made by M-x report-emacs-bug transfers
514 the report to your desktop's preferred mail client, if there is one.
515 This uses either the "xdg-email" utility, or Mac OS's "open" command.
516
517 *** See Changes in Specialized Modes and Packages for SMTPmail changes
518 and Mail mode changes
519
520 ** Emacs server and client changes
521
522 *** New option `server-port' specifies the port for TCP Emacs servers.
523
524 *** New emacsclient argument -q/--quiet suppresses some status messages.
525
526 *** New emacsclient argument --frame-parameters specifies the frame
527 parameters of any newly-created graphical frame.
528
529 *** If emacsclient shuts down due to Emacs signaling an error,
530 its exit status is 1.
531
532 *** New emacsclient argument --parent-id ID.
533 This opens a client frame in parent X window ID, via XEmbed, similar
534 to the --parent-id argument to Emacs.
535
536 ** Internationalization changes
537
538 *** Emacs now supports display and editing of bidirectional text.
539 Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are
540 displayed in the correct visual order as expected by users of those
541 scripts. The display reordering is a "full bidirectionality" class
542 implementation of the Unicode Bidirectional Algorithm (UBA). Buffers
543 with no RTL text should look exactly the same as before.
544
545 **** New buffer-local variable `bidi-display-reordering'.
546 To disable display reordering in a buffer, change this to nil.
547
548 **** New buffer-local variable `bidi-paragraph-direction'.
549 If nil (the default), Emacs determines the base direction of each
550 paragraph from its text, as specified by the UBA. Setting the value
551 to `right-to-left' or `left-to-right' forces a base direction on each
552 paragraph.
553
554 Paragraphs with right-to-left base direction are displayed starting at
555 the right window edge.
556
557 *** Enhanced support for characters with no glyphs in available fonts,
558 or, on text terminals, characters that cannot be encoded by the
559 terminal coding system. The new option `glyphless-char-display-control'
560 specifies how to display them: as a hexadecimal code in a box, a thin
561 1-pixel space, an empty box, etc.
562
563 *** New input methods: farsi, farsi-translit, bulgarian-alt-phonetic.
564
565 *** `nobreak-char-display' now also highlights Unicode hyphen chars
566 (U+2010 and U+2011).
567
568 *** New Hebrew translation of the Emacs Tutorial.
569 Type `C-u C-h t' to choose it in case your language setup doesn't
570 automatically select it.
571
572 ** An Emacs Lisp package manager is now included.
573 This is a convenient way to download and install additional packages,
574 from a package repository at http://elpa.gnu.org.
575
576 *** M-x list-packages shows a list of packages, which can be
577 selected for installation.
578
579 *** New command `describe-package', bound to `C-h P'.
580
581 *** By default, all installed packages are loaded automatically when
582 Emacs starts up. To disable this, set `package-enable-at-startup' to
583 nil. To specify the packages to load, customize `package-load-list'.
584
585 ** Custom theme changes
586
587 *** New command `M-x customize-themes', which provides a convenient
588 interface for enabling and disabling Custom themes.
589
590 *** New option `custom-theme-load-path' is the load path for themes.
591 Emacs no longer looks for Custom themes in `load-path'. The default
592 value of `custom-theme-load-path' says to look for themes in
593 `custom-theme-directory', followed by a subdirectory of
594 `data-directory' named "themes/", which contains a small selection of
595 built-in Custom themes.
596
597 *** New option `custom-safe-themes' records known-safe theme files.
598 If a theme is not in this list, Emacs queries before loading it, and
599 offers to save the theme to `custom-safe-themes' automatically. By
600 default, all themes included in Emacs are treated as safe.
601
602 ** Improved GTK integration
603
604 *** GTK scroll-bars are now placed on the right by default.
605 The function `set-scroll-bar-mode' can change this.
606
607 *** GTK tool bars can have just text, just images or images and text.
608 Customize `tool-bar-style' to choose the style. On a Gnome desktop,
609 the default is taken from desktop settings.
610
611 *** GTK tool bars can be placed on any edge of the frame.
612 The frame-parameter tool-bar-position controls this. It takes the
613 values top, left, right or bottom. The Options => Show/Hide menu has
614 entries for this.
615
616 *** The default colors for selected text (the `region' face) are taken
617 from the GTK theme when Emacs is built with GTK.
618
619 *** Emacs uses GTK tooltips by default if built with GTK.
620 You can disable this by changing `x-gtk-use-system-tooltips' to nil.
621
622 ** Graphical interface changes
623
624 *** On graphical displays, the mode-line no longer ends in dashes.
625 Also, the first dash (which does not indicate anything) is just
626 displayed as a space.
627
628 *** `menu-bar-select-buffer-function' lets you choose another operation
629 instead of `switch-to-buffer' when selecting an item in the Buffers menu.
630
631 *** Lucid menus and dialogs can display antialiased fonts if Emacs is
632 built with Xft. These fonts can be set via X resources, for example:
633 Emacs.pane.menubar.font: Courier-12
634
635 ** Exiting changes
636
637 *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP,
638 or if it receives a SIGINT signal in batch mode.
639
640 *** `kill-emacs-hook' is now also run in batch mode.
641 Third-party code which adds to `kill-emacs-hook' should check if they
642 do the right thing in batch mode.
643
644 ** Scrolling changes
645
646 *** New scrolling commands `scroll-up-command' and `scroll-down-command'
647 (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom
648 of buffer at first key-press (instead they move to top/bottom of buffer)
649 when `scroll-error-top-bottom' is non-nil.
650
651 *** New option `scroll-error-top-bottom' (see above).
652
653 *** New scrolling commands `scroll-up-line' and `scroll-down-line'
654 scroll a line instead of full screen.
655
656 *** New property `scroll-command' should be set on a command's symbol to
657 define it as a scroll command affected by `scroll-preserve-screen-position'.
658
659 *** If you customize `scroll-conservatively' to a value greater than 100,
660 Emacs will never recenter point in the window when it scrolls due to
661 cursor motion commands or commands that move point (e.f., `M-g M-g').
662 Previously, you needed to use `most-positive-fixnum' as the value of
663 `scroll-conservatively' to achieve the same effect.
664
665 *** "Aggressive" scrolling now honors the scroll margins.
666 If you customize `scroll-up-aggressively' or
667 `scroll-down-aggressively' and move point off the window, Emacs now
668 scrolls the window so as to avoid positioning point inside the scroll
669 margin.
670
671 ** Basic SELinux support has been added.
672 This requires Emacs to be linked with libselinux at build time.
673
674 *** Emacs preserves the SELinux file context when backing up.
675 Also, the function `copy-file' has an extra optional argument for
676 preserving SELinux context, and the return value of `backup-buffer'
677 now includes the SELinux context.
678
679 *** New functions `file-selinux-context' and `set-file-selinux-context'
680 get and set the SELinux context of a file.
681
682 ** Trash changes
683
684 *** `delete-by-moving-to-trash' now only affects commands that specify
685 trashing. This avoids inadvertently trashing temporary files.
686
687 *** Calling `delete-file' or `delete-directory' with a prefix argument
688 now forces true deletion, regardless of `delete-by-moving-to-trash'.
689
690 ** File- and directory-local variable changes
691
692 *** You can stop directory local vars from applying to subdirectories.
693 Add an element (subdirs . nil) to the alist portion of any variables
694 settings to indicate that the section should not apply to
695 subdirectories.
696
697 *** Directory local variables can apply to some file-less buffers.
698 Affected modes include dired, vc-dir, and log-edit. For example,
699 adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will
700 turn on `whitespace-mode' for *vc-diff* buffers. Modes should call
701 `hack-dir-local-variables-non-file-buffer' to support this.
702
703 *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated.
704 Instead, use "eval: (minor-mode 1)".
705
706 *** The variable `inhibit-first-line-modes-regexps' has been renamed
707 to `inhibit-local-variables-regexps'. As the name suggests, it now
708 applies to ALL file local variables, not just -*- lines. The
709 associated `inhibit-first-line-modes-suffixes' has been renamed in the
710 corresponding way.
711
712 ** Window changes
713
714 *** The `quit-window' command now restores the last buffer displayed
715 in the quitted window.
716
717 *** Resizing an Emacs frame now preserves proportional window sizes,
718 modulo restrictions like window minimum sizes and fixed-size windows.
719
720 *** The behavior of `display-buffer' is now customizable in detail.
721
722 **** New option `display-buffer-base-action' specifies a list of
723 user-determined display "actions" (functions and optional arguments
724 for choosing the displaying window).
725
726 This takes precedence over the default display action, which is
727 specified by `display-buffer-fallback-action'.
728
729 **** New option `display-buffer-alist' maps buffer name regexps to
730 display actions, taking precedence over `display-buffer-base-action'.
731
732 *** New option `window-combination-limit'.
733 The new option `window-combination-limit' allows to return the space
734 obtained for resizing or creating a window more reliably to the window
735 from which such space was obtained.
736
737 *** New option `window-combination-resize'.
738 The new option `window-combination-resize' allows to split a window that
739 otherwise cannot be split because it's too small by stealing space from
740 other windows in the same combination. Subsequent resizing or deletion
741 of the window will resize all windows in the same combination as well.
742
743 *** New option `frame-auto-hide-function' lets you choose between
744 iconifying or deleting a frame when burying a buffer in a dedicated
745 frame, or quitting a window showing a buffer in a frame of its own.
746
747 *** New commands `maximize-window' and `minimize-window'.
748 These maximize and minimize the size of a window within its frame.
749
750 *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'.
751 These functions allow to navigate through the live buffers that have
752 been shown in a specific window.
753
754 ** Minibuffer changes
755
756 *** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'.
757 This is handy for minibuffer-only frames, and is also used for the feature
758 where mouse-1 pops up *Messages*"', which can now easily be changed.
759
760 *** Minibuffers set `truncate-lines' to nil.
761 If you want to change the value to something else, you could use
762 for example `minibuffer-setup-hook'.
763
764 ** `auto-mode-case-fold' is now enabled by default.
765
766 ** `backup-by-copying-when-mismatch' now defaults to t.
767
768 ** New basic faces `error', `warning', `success'.
769 These are used to highlight text indicating failure, caution or
770 successful operation.
771
772 ** New option `list-colors-sort' defines the color sort order
773 for `list-colors-display'.
774
775 ** The variable `focus-follows-mouse' now always defaults to nil.
776
777 \f
778 * Editing Changes in Emacs 24.1
779
780 ** Search changes
781
782 *** C-y in Isearch is now bound to `isearch-yank-kill', instead of
783 `isearch-yank-line'.
784
785 *** M-y in Isearch is now bound to `isearch-yank-pop', instead of
786 `isearch-yank-kill'.
787
788 *** M-s C-e in Isearch is now bound to `isearch-yank-line'.
789
790 ** New commands `count-words-region' and `count-words'.
791
792 *** M-= is bound to `count-words-region', not `count-lines-region'.
793 The `count-words-region' command, when called interactively, reports
794 the number of lines, words, and characters in the region. It is a
795 superset of the old `count-lines-region', which is now an obsolete
796 alias for it.
797
798 ** The command `just-one-space' (M-SPC), if given a negative argument,
799 also deletes newlines around point.
800
801 ** Deletion changes
802
803 *** New option `delete-active-region'.
804 If non-nil, [delete] and DEL delete the region if it is active and no
805 prefix argument is given. If set to `kill', those commands kill
806 instead.
807
808 *** New command `delete-forward-char', bound to [delete].
809 This is meant for interactive use, and obeys `delete-active-region'.
810 The command `delete-char' does not obey `delete-active-region'.
811
812 *** `delete-backward-char' is now a Lisp function.
813 Apart from obeying `delete-active-region', its behavior is unchanged.
814 However, the byte compiler now warns if it is called from Lisp; Lisp
815 callers should use delete-char with a negative argument instead.
816
817 *** The option `mouse-region-delete-keys' has been deleted.
818
819 ** Selection changes.
820
821 The default handling of clipboard and primary selections has been
822 changed to conform with modern X applications. In short, most
823 commands for killing and yanking text now use the clipboard, while
824 mouse commands use the primary selection.
825
826 In the following, we provide a list of these changes, followed by a
827 list of steps to get the old behavior back if you prefer that.
828
829 *** `select-active-regions' now defaults to t.
830 Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
831 the kill ring. The selected text is put in the primary selection, if
832 the system possesses a separate primary selection facility (e.g. X).
833
834 **** `select-active-regions' also accepts a new value, `only'.
835 This means to only set the primary selection for temporarily active
836 regions (usually made by mouse-dragging or shift-selection);
837 "ordinary" active regions, such as those made with C-SPC followed by
838 point motion, do not alter the primary selection.
839
840 **** `mouse-drag-copy-region' now defaults to nil.
841
842 *** mouse-2 is now bound to `mouse-yank-primary'.
843 This pastes from the primary selection, ignoring the kill-ring.
844 Previously, mouse-2 was bound to `mouse-yank-at-click'.
845
846 *** `x-select-enable-clipboard' now defaults to t on all platforms.
847
848 *** `x-select-enable-primary' now defaults to nil.
849 Thus, commands that kill text or copy it to the kill-ring (such as
850 M-w, C-w, and C-k) also use the clipboard---not the primary selection.
851
852 **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
853 exactly equivalent to M-w, C-w, and C-y respectively.
854
855 **** Note that on MS-Windows, `x-select-enable-clipboard' was already
856 non-nil by default, as Windows does not support the primary selection
857 between applications.
858
859 *** To return to the previous behavior, do the following:
860
861 **** Change `select-active-regions' to nil.
862 **** Change `mouse-drag-copy-region' to t.
863 **** Change `x-select-enable-primary' to t (on X only).
864 **** Change `x-select-enable-clipboard' to nil.
865 **** Bind `mouse-yank-at-click' to mouse-2.
866
867 *** Support for X cut buffers has been removed.
868
869 *** X clipboard managers are now supported.
870 To inhibit this, change `x-select-enable-clipboard-manager' to nil.
871
872 ** New command `C-x r N' (`rectangle-number-lines') numbers the lines
873 in the current rectangle. With a prefix argument, this prompts for a
874 number to count from and for a format string.
875
876 ** `redisplay-dont-pause' now defaults to t.
877 This makes Emacs feel more responsive to editing commands that arrive
878 at high rate, e.g. if you lean on some key, because stopping redisplay
879 in the middle (when this variable is nil) forces more expensive
880 updates later on, and Emacs appears to be unable to keep up.
881
882 ** The behavior of <TAB> for active regions in Text mode has changed.
883 In Text and related modes, typing <TAB> (`indent-for-tab-command')
884 when the region is active causes Emacs to indent all the lines in the
885 region, aligning them with the line previous to the first line in the
886 region (or with the left margin if there is no previous line).
887
888 ** When `occur' is called with a prefix argument, matching strings are
889 collected into the `*Occur*' buffer without line numbers. If there
890 are parenthesized subexpressions in the specified regexp, `occur'
891 reads replacement text that may contain \\& and \\N whose convention
892 follows `replace-match'.
893
894 \f
895 * Changes in Specialized Modes and Packages in Emacs 24.1
896
897 ** Archive Mode has basic support for browsing and updating 7z archives.
898
899 ** BibTeX mode
900
901 *** BibTeX mode now supports biblatex.
902 Use the variable `bibtex-dialect' to select different BibTeX dialects.
903 `bibtex-entry-field-alist' is now an obsolete alias for
904 `bibtex-BibTeX-entry-alist'.
905
906 *** New command `bibtex-search-entries', bound to C-c C-a.
907
908 *** New `bibtex-entry-format' option `sort-fields', disabled by default.
909
910 *** New variable `bibtex-search-entry-globally'.
911
912 ** Browse-url
913
914 *** New option `browse-url-mailto-function' specifies how to handle "mailto:"s.
915
916 *** The default browser used by the package is now the "xdg-open" program,
917 on platforms that support it. This calls your desktop's preferred browser.
918
919 ** Calendar, Diary, and Appt
920
921 *** Diary entries can contain non-printing "comments".
922 See the variable `diary-comment-start'.
923
924 *** Appointments can specify their individual warning times.
925 See the variable `appt-warning-time-regexp'.
926
927 *** The function specified by `appt-disp-window-function' may be passed
928 lists of arguments if multiple appointments are due at similar times.
929 If you are using a custom function for this, you should update it.
930
931 *** New function `diary-hebrew-birthday'.
932
933 *** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array'
934 may no longer be nil, but must all be strings.
935
936 *** The obsolete (since Emacs 22.1) method of enabling the appt
937 package by adding `appt-make-list' to `diary-hook' has been removed.
938 Use `appt-activate' instead.
939
940 *** Some appt variables (obsolete since Emacs 22.1) have been removed:
941 appt-issue-message (use the function appt-activate)
942 appt-visible/appt-msg-window (use the variable appt-display-format)
943
944 *** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
945 view-diary-entries, list-diary-entries, show-all-diary-entries
946
947 ** CC Mode
948
949 *** New feature to "guess" the style in an existing buffer.
950 The main entry point is M-x c-guess.
951
952 *** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang).
953
954 *** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes.
955 Thus C-M-a will, by default, go to the beginning of the immediate function,
956 not the top level.
957
958 *** "Macros with semicolons" can be registered for correct indentation.
959 Where such a macro ends a line (no semicolon) the next statement is no longer
960 parsed as a statement continuation.
961
962 ** Comint and modes derived from it use the standard completion code.
963
964 ** Compilation mode
965
966 *** Compilation mode can be used without Font Lock mode.
967 `compilation-parse-errors-function' is now obsolete.
968
969 *** New variable `compilation-filter-start', which is bound while
970 `compilation-filter-hook' runs. It records the start position of the
971 text inserted by `compilation-filter'.
972
973 *** `compilation-error-screen-columns' and `compilation-first-column'
974 are obeyed in the editing buffer. So programming language modes can
975 set them, whereas previously only the value in the *Compilation*
976 buffer was used.
977
978 ** Customize
979
980 *** Customize buffers now contain a search field.
981 The search is performed using `customize-apropos'.
982 To turn off the search field, set `custom-search-field' to nil.
983
984 *** Custom options now start out hidden if at their default values.
985 Use the arrow to the left of the option name to toggle visibility.
986
987 *** custom-buffer-sort-alphabetically now defaults to t.
988
989 *** The color widget now has a "Choose" button, which allows you to
990 choose a color via `list-colors-display'.
991
992 ** D-Bus
993
994 *** It is now possible to access buses other than the default system
995 or session bus.
996
997 *** The `dbus-register-method' and `dbus-register-property' functions
998 optionally do not register names.
999
1000 *** The new function `dbus-register-service' registers a known service
1001 name on a D-Bus without also registering a property or a method.
1002
1003 ** Dired-x
1004
1005 *** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'),
1006 if called with a prefix argument, read a file name from the minibuffer
1007 instead of using the current buffer.
1008
1009 *** The "dired local variables" feature of Dired-x is obsolete.
1010 The standard directory local variables feature replaces it.
1011
1012 ** ERC changes
1013
1014 *** New options `erc-autojoin-timing' and `erc-autojoin-delay',
1015 controlling attempts to autojoin a channel.
1016
1017 *** New variable `erc-coding-system-precedence': If we use `undecided'
1018 as the server coding system, this variable will then be consulted.
1019 The default is to decode strings that can be decoded as utf-8 as
1020 utf-8, and do the normal `undecided' decoding for the rest.
1021
1022 ** Eshell changes
1023
1024 *** The default value of `eshell-directory-name' has changed
1025 to be an "eshell" directory in `user-emacs-directory'.
1026 The old "~/.eshell/" directory is still used if it exists, though.
1027
1028 ** gdb-mi
1029
1030 *** The M-x gdb command now uses the GDB Machine Interface protocol.
1031 It now supports multithread non-stop debugging and simultaneous
1032 debugging of several threads.
1033
1034 ** Image mode
1035
1036 *** RET (`image-toggle-animation') toggles animation, if applicable.
1037 Animation plays once, unless the option `image-animate-loop' is non-nil.
1038
1039 ** Info
1040
1041 *** New command M-x info-display-manual displays a named Info manual.
1042 If that manual is already visited in some Info buffer, it displays
1043 that buffer. (This is handy if you have many manuals in many *info*
1044 buffers, and don't remember the name of the buffer visiting the manual
1045 you want to consult.) Otherwise, it loads and displays the manual.
1046
1047 *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'.
1048 This is for compatibility with the stand-alone Info reader program,
1049 and also because `Info-edit' is a rarely used command that is disabled
1050 by default.
1051
1052 ** Mail mode changes (not Message mode)
1053
1054 *** New command M-x mail-add-attachment for adding MIME attachments
1055
1056 *** The command M-x mail-attach-file was renamed to M-x mail-insert-file.
1057 (Its name is misleading, since it has nothing to do with MIME
1058 attachments.) The old name is now an obsolete alias to the new name.
1059
1060 ** MH-E has been updated to MH-E version 8.3.1.
1061 See MH-E-NEWS for details.
1062
1063 ** Modula-2 mode provides auto-indentation.
1064
1065 ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
1066
1067 ** nXML mode no longer binds C-RET to `nxml-complete'.
1068 Completion is now performed via `completion-at-point', bound to C-M-i
1069 or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the
1070 default), this performs tag completion.
1071
1072 ** Org mode has been updated to version 7.8.09.
1073 See ORG-NEWS for details.
1074
1075 ** Prolog mode has been completely revamped, with lots of additional
1076 functionality such as more intelligent indentation, electricity,
1077 support for more variants, including Mercury, and a lot more.
1078
1079 ** Rmail
1080
1081 *** The command `rmail-epa-decrypt' decrypts OpenPGP data
1082 in the Rmail incoming message.
1083
1084 *** The variable `rmail-message-filter' no longer has any effect.
1085 This change was made in Emacs 23.1 but was not advertised at the time.
1086 Try using `rmail-show-message-hook' instead.
1087
1088 ** Shell mode
1089
1090 *** M-x shell prompts for the shell path name if the default directory
1091 is a remote file name and neither the environment variable $ESHELL nor
1092 the variable `explicit-shell-file-name' is set.
1093
1094 *** TAB is now bound to the standard `completion-at-point' command,
1095 which now implements the pcomplete rules for shell command completion.
1096
1097 ** SMTPmail
1098
1099 *** SMTPmail now uses encrypted connections (via STARTTLS) by default
1100 if the mail server supports them. This uses either built-in GnuTLS
1101 support, or the starttls.el library. Customize `smtpmail-stream-type'
1102 to change this.
1103
1104 *** The variable `smtpmail-auth-credentials' has been removed.
1105 By default, the information is now stored in the file ~/.authinfo.
1106 This was the default value of smtpmail-auth-credentials. If you had
1107 customized smtpmail-auth-credentials to a list of user names and
1108 passwords, those settings are not used. During your first connection
1109 to the smtp server, Emacs will prompt for the user name and password,
1110 and offer to save them to ~/.authinfo. Or you can manually copy the
1111 credentials to ~/.authinfo. For example, if you had
1112
1113 (setq smtpmail-auth-credentials
1114 '(("mail.example.org" 25 "jim" "s!cret")))
1115
1116 then the equivalent line in ~/.authinfo would be
1117
1118 machine mail.example.org port 25 login jim password s!cret
1119
1120 See the auth-source manual for more information, e.g. on encrypting
1121 the credentials file.
1122
1123 *** The variable `smtpmail-starttls-credentials' has been removed.
1124 If you had that set, you need to put
1125
1126 machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert"
1127
1128 in your ~/.authinfo file instead.
1129
1130 ** SQL mode
1131
1132 *** New options `sql-port', `sql-connection-alist', `sql-send-terminator',
1133 and `sql-oracle-scan-on'.
1134
1135 *** New options controlling prompting for login parameters.
1136 Each supported product has a custom variable `sql-*-login-params',
1137 which is a list of the parameters to be prompted for before a
1138 connection is established.
1139
1140 *** The command `sql-product-interactive' now takes a prefix argument,
1141 which causes it to prompt for an SQL product.
1142
1143 *** Product-specific SQL interactive commands now take prefix arguments.
1144 These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.),
1145 given a prefix argument, prompt for a name for the SQL interactive
1146 buffer. This reduces the need for calling `sql-rename-buffer'.
1147
1148 *** SQL interactive modes suppress command continuation prompts, and
1149 replace tabs with spaces. The first change impacts multiple line SQL
1150 statements entered with C-j between each line, statements yanked into
1151 the buffer and statements sent with `sql-send-*' functions. The
1152 second prevents the MySQL and Postgres interpreters from listing
1153 object name completions when sent text via `sql-send-*' functions.
1154
1155 *** New command `sql-connect' starts a predefined SQLi session,
1156 using the login parameters from `sql-connection-alist'.
1157
1158 *** New "Save Connection" menu item in SQLi buffers.
1159 This gathers the login params specified for the SQLi session, if it
1160 was not started by a connection, and saves them as a new connection.
1161
1162 *** New commands for listing database objects and details:
1163 sql-list-all and sql-list-table.
1164
1165 *** An API for manipulating SQL product definitions has been added.
1166
1167 ** TeX modes
1168
1169 *** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
1170
1171 ** Tramp
1172
1173 *** New inline access method "ksu" (kerberized su).
1174
1175 *** The following access methods are discontinued: "ssh1_old",
1176 "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish".
1177
1178 *** The user option `remote-file-name-inhibit-cache' controls whether
1179 remote file attributes are cached for better performance.
1180
1181 *** The option `ange-ftp-binary-file-name-regexp' has changed its
1182 default value to "".
1183
1184 *** Handlers for `file-selinux-context' and `set-file-selinux-context'
1185 for remote machines which support SELinux.
1186
1187 ** New function `url-queue-retrieve', which behaves like url-retrieve,
1188 but with limits (`url-queue-parallel-processes', `url-queue-timeout') on
1189 the degree of parallelism.
1190
1191 ** VC and related modes
1192
1193 *** Support for pulling on distributed version control systems.
1194 The command C-x v + (`vc-pull') runs a "pull" operation, if it is
1195 supported (currently with Bzr, Git, and Mercurial), to update the
1196 current branch and working tree. A prefix argument means to prompt
1197 the user for specifics, e.g. a pull location.
1198
1199 *** `vc-update' is now an alias for `vc-pull'.
1200
1201 *** Support for merging on distributed version control systems.
1202 The command C-x v m (`vc-merge') now runs a "merge" operation, if it
1203 is supported (currently with Bzr, Git, and Mercurial), to merge
1204 changes from another branch into the current one. It prompts for
1205 specifics, e.g. a merge source.
1206
1207 *** New option `vc-revert-show-diff' controls whether `vc-revert'
1208 shows a diff while querying the user. It defaults to t.
1209
1210 *** Log entries in some Log View buffers can be toggled to display a
1211 longer description by typing RET (log-view-toggle-entry-display).
1212 This is currently supported for Bzr, Git, and Mercurial (to support
1213 another backend, define a `log-view-expanded-log-entry-function').
1214 In the Log View buffers made by C-x v L (`vc-print-root-log'), you can
1215 use this to display the full log entry for the revision at point.
1216
1217 *** New command `vc-ediff' allows visual comparison of two revisions
1218 of a file similar to `vc-diff', but using ediff backend.
1219
1220 *** The option `vc-initial-comment' was removed in Emacs 23.2, but
1221 this was not advertised at the time.
1222
1223 *** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'.
1224 Since Emacs 23, it has done the same thing as `toggle-read-only', but
1225 this was not advertised at the time.
1226
1227 ** Obsolete modes
1228
1229 *** abbrevlist.el
1230
1231 *** erc-hecomplete.el (use erc-pcomplete.el instead)
1232
1233 *** partial-completion-mode (complete.el) is obsolete.
1234 You can get a comparable behavior with:
1235 (setq completion-styles '(partial-completion initials))
1236 (setq completion-pcm-complete-word-inserts-delimiters t)
1237
1238 *** pc-mode.el is obsolete (CUA mode is much more comprehensive).
1239
1240 *** pgg is obsolete (use EasyPG instead).
1241
1242 *** sregex.el is obsolete, since rx.el is a strict superset.
1243
1244 *** s-region.el and pc-select.el are obsolete.
1245 They are superseded by shift-select-mode, enabled by default since 23.1.
1246
1247 *** vc-mcvs.el is obsolete (for lack of a maintainer).
1248
1249 ** Miscellaneous
1250
1251 *** The Landmark game is now invoked with `landmark', not `lm'.
1252 Its functions and variables have been similarly renamed.
1253
1254 *** In `ido-file-completion-map', C-v is no longer bound to `ido-toggle-vc'.
1255 (This interfered with cua-mode.)
1256
1257 *** f90.el has some support for Fortran 2008 syntax.
1258
1259 *** `copyright-fix-years' can optionally convert consecutive years to ranges.
1260
1261 *** New command `nato-region' converts text to NATO phonetic alphabet.
1262
1263 \f
1264 * New Modes and Packages in Emacs 24.1
1265
1266 ** Occur Edit mode applies edits made in *Occur* buffers to the
1267 original buffers. It is bound to "e" in Occur mode.
1268
1269 ** New global minor mode electric-pair-mode.
1270 When enabled, typing an open parenthesis automatically inserts the
1271 matching closing one.
1272
1273 ** New global minor mode electric-indent-mode.
1274 When enabled, typing certain characters triggers reindentation.
1275 Major modes wishing to use this can set electric-indent-chars or
1276 electric-indent-functions.
1277
1278 ** New global minor mode electric-layout-mode.
1279 When enabled, typing certain characters automatically inserts newlines.
1280 Major modes wishing to use this can set electric-layout-rules.
1281
1282 ** tabulated-list.el provides a generic major mode for tabulated data,
1283 from which other modes can be derived.
1284
1285 ** pcase.el provides the ML-style pattern matching macro `pcase'.
1286
1287 ** secrets.el is an implementation of the Secret Service API, an
1288 interface to password managers like GNOME Keyring or KDE Wallet. The
1289 Secret Service API requires D-Bus for communication. The command
1290 `secrets-show-secrets' offers a buffer with a visualization of the
1291 secrets.
1292
1293 ** notifications.el provides an implementation of the Desktop
1294 Notifications API. It requires D-Bus for communication.
1295
1296 ** soap-client.el supports access to SOAP web services from Emacs.
1297 soap-inspect.el is an interactive inspector for SOAP WSDL structures.
1298
1299 ** New generic mode, xmodmap-generic-mode, for xmodmap files.
1300
1301 ** New emacs-lock.el package.
1302 The previous version has been moved to obsolete/old-emacs-lock.el.
1303 Now, there is a proper minor mode `emacs-lock-mode'. Protection
1304 against exiting Emacs and killing the buffer can be set separately.
1305 The mechanism for automatically turning off protection for buffers
1306 with dead inferior processes has been generalized.
1307
1308 \f
1309 * Incompatible Lisp Changes in Emacs 24.1
1310
1311 ** Passing a nil argument to a minor mode function call now ENABLES
1312 the minor mode unconditionally. This is so that you can write e.g.
1313
1314 (add-hook 'text-mode-hook 'foo-mode)
1315
1316 to enable foo-mode in Text mode buffers, removing the need for
1317 `turn-on-foo-mode' style functions. This affects all mode commands
1318 defined by `define-minor-mode'. If called interactively, the mode
1319 command still toggles the minor mode.
1320
1321 ** The return value of `backup-buffer' has changed.
1322 It is now a list of three elements, where the second element is a list
1323 describing the original file's SELinux context. If Emacs or the
1324 system lacks SELinux support, the context list is (nil nil nil nil).
1325 See "Basic SELinux support" above, under "Changes in Emacs 24.1".
1326
1327 ** `char-direction-table' and the `char-direction' function were deleted.
1328 They were buggy and inferior to the new support of bidirectional
1329 editing introduced in Emacs 24. If you need the bidirectional
1330 properties of a character, use `get-char-code-property' with the last
1331 argument `bidi-class'.
1332
1333 ** `copy-directory' now copies the source directory as a subdirectory
1334 of the target directory, if the latter is an existing directory. The
1335 new optional arg COPY-CONTENTS, if non-nil, makes the function copy
1336 the contents directly into a pre-existing target directory.
1337
1338 ** For mouse click input events in the text area, the Y pixel
1339 coordinate in the POSITION list now counts from the top of the text
1340 area, excluding any header line. Previously, it counted from the top
1341 of the header line.
1342
1343 ** Support for "old-style" backquotes, obsolete for 10+ years, has
1344 been further reduced. Now a backquote not followed by a space is
1345 always treated as a "new-style" backquote. Please remove all
1346 "old-style" backquotes from your code. If your code uses backquotes
1347 as documented in the Elisp manual, and compiles without warning, then
1348 you have nothing to do in this regard. Code not following the
1349 appropriate conventions may fail to compile.
1350
1351 The most common cause of trouble seems to be an old-style backquote
1352 followed by a newline. Another cause of trouble is vector notation
1353 for key sequence notation: instead of [(control ,)] and [(control ')],
1354 you should write [(control ?,)] and [(control ?')], which will work in
1355 older Emacsen too.
1356
1357 ** The macro `eval-at-startup' was removed in Emacs 23.2, but this
1358 was not advertised at the time. The function `custom-initialize-delay'
1359 replaced all known uses.
1360
1361 ** `view-buffer' now treats special mode-class in the same way that
1362 `view-file' has since Emacs 22 (i.e. it won't enable View mode if the
1363 major mode is special).
1364
1365 ** Menu and tool bar changes
1366
1367 *** During startup, Emacs no longer adds entries for `menu-bar-lines'
1368 and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'.
1369 With these alist entries omitted, `make-frame' checks the value of the
1370 variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create
1371 a menu-bar or tool-bar, respectively. If the alist entries are added,
1372 they override the value of `menu-bar-mode'/`tool-bar-mode'.
1373
1374 *** The menu bar bindings's caches are not used any more.
1375 Use (where-is-internal <def> nil t) instead.
1376
1377 ** Regions created by mouse dragging are now normal active regions,
1378 similar to those created by shift-selection (see Selection changes
1379 above). In previous Emacs versions, these regions were delineated by
1380 `mouse-drag-overlay'; that variable has been removed.
1381
1382 ** The fourth argument of `filter-buffer-substring' has been removed.
1383 If you want to remove text properties from the final result, simply
1384 pass the result through substring-no-properties.
1385
1386 ** cl.el no longer provides `cl-19'.
1387
1388 ** The following obsolete functions and aliases have been removed
1389 (the appropriate new function is given in parentheses; "not needed"
1390 means you can just remove all calls to the function in question):
1391
1392 *** `comint-kill-output' (`comint-delete-output')
1393 *** `decompose-composite-char' (`char-to-string')
1394 *** `outline-visible' (`outline-invisible-p')
1395 *** `internal-find-face' (`facep')
1396 *** `internal-get-face' (`facep and check-face')
1397 *** `frame-update-faces' (not needed)
1398 *** `frame-update-face-colors' (`frame-set-background-mode')
1399 *** `x-frob-font-weight' and `x-frob-font-slant' (`make-face-*' functions)
1400 *** `x-make-font-bold and x-make-font-demibold (`make-face-bold')
1401 *** `x-make-font-italic' and `x-make-font-oblique' (`make-face-italic')
1402 *** `x-make-font-bold-italic' (`make-face-bold-italic')
1403 *** `x-make-font-unbold' (`make-face-unbold')
1404 *** `x-make-font-unitalic' (`make-face-unitalic')
1405 *** `mldrag-drag-mode-line' (`mouse-drag-mode-line')
1406 *** `mldrag-drag-vertical-line' (`mouse-drag-vertical-line')
1407 *** `iswitchb-default-keybindings' (`iswitchb-mode')
1408 *** `char-bytes' (== 1)
1409 *** `isearch-return-char' (`isearch-printing-char')
1410 *** `make-local-hook' (not needed)
1411 *** `set-screen-height' (`set-frame-height')
1412 *** `set-screen-width' (`set-frame-width')
1413
1414 ** The following obsolete variables and varaliases have been removed
1415 (the appropriate new variable is given in parentheses):
1416
1417 *** `checkdoc-minor-keymap' (`checkdoc-minor-mode-map')
1418 *** `vc-header-alist' (`vc-BACKEND-header')
1419 *** `directory-sep-char' (== ?/)
1420 *** `font-lock-defaults-alist' (`font-lock-defaults')
1421 *** `e' (`float-e').
1422
1423 ** The following obsolete files were removed:
1424 sc.el, x-menu.el, rnews.el, rnewspost.el
1425
1426 ** The format of the finder-inf.el file has changed, since the Finder
1427 mechanism is now based on the package system. The variable
1428 `finder-package-info' is replaced by `package--builtins' and
1429 `finder-keywords-hash'.
1430
1431 ** When generating autoloads, `update-directory-autoloads' no longer
1432 assumes every inspected file is in your `load-path'. It instead
1433 generates relative names according to the current `load-path'.
1434
1435 \f
1436 * Lisp changes in Emacs 24.1
1437
1438 ** Code can now use lexical scoping by default instead of dynamic scoping.
1439 The `lexical-binding' variable enables lexical scoping for local
1440 variables. It is typically set via a file-local variable in the first
1441 line of the file, in which case it applies to all the code in that
1442 file.
1443
1444 *** `eval' takes a new optional argument `lexical' to choose the new lexical
1445 binding instead of the old dynamic binding mode.
1446
1447 *** Lexically scoped interpreted functions are represented with a new form
1448 of function value which looks like (closure ENV ARGS &rest BODY).
1449
1450 *** New macro `letrec' to define recursive local functions.
1451
1452 *** `defvar' and `defconst' now mark the variable as special (dynamic).
1453 So do `defcustom' and other forms that call `defvar' as a subroutine.
1454
1455 *** New function `special-variable-p' to check whether a variable is
1456 declared as dynamically bound.
1457
1458 *** The form ((lambda ...) ...) is deprecated.
1459
1460 ** An Emacs Lisp testing tool is now included.
1461 Emacs Lisp developers can use this tool to write automated tests for
1462 their code. See the ERT info manual for details.
1463
1464 ** Changes for bidirectional display and editing
1465
1466 *** New function `current-bidi-paragraph-direction'.
1467 This returns the base direction of the paragraph at point.
1468
1469 *** New function `bidi-string-mark-left-to-right'.
1470 Given a string containing characters from right-to-left scripts, this
1471 function returns another string which can be safely inserted into a
1472 buffer, such that any following text will be always displayed to the
1473 right of that string. (This works by appending an invisible Unicode
1474 "LEFT-TO-RIGHT MARK" character if the argument string might need it.)
1475
1476 This is useful when the buffer has overall left-to-right paragraph
1477 direction and you need to insert a string whose contents are not known
1478 in advance, without disrupting the layout of the line.
1479
1480 ** Window changes
1481
1482 *** Window tree functions are accessible in Elisp.
1483 Functions are provided to return the parent, siblings or child windows
1484 of any window including internal windows (windows not associated with a
1485 buffer) in the window tree.
1486
1487 **** New function `window-valid-p' gives non-nil for live and internal
1488 windows.
1489
1490 **** Window manipulation can deal with internal windows.
1491 Many window handling functions like `split-window', `delete-window', or
1492 `delete-other-windows' as well as the window resizing functions can now
1493 act on any window including internal ones.
1494
1495 *** window-total-height/-width vs window-body-height/-width.
1496 The function `window-height' has been renamed to `window-total-height'
1497 and `window-width' has been renamed to `window-body-width'. The old
1498 names are provided as aliases. Two new functions `window-total-width'
1499 and `window-body-height' are provided.
1500
1501 *** Window parameters specific to window handling functions.
1502 For each window you can specify a parameter to override the default
1503 behavior of a number of functions like `split-window', `delete-window'
1504 and `delete-other-windows'. The variable `ignore-window-parameters'
1505 allows to ignore processing such parameters.
1506
1507 *** New semantics of third argument of `split-window'.
1508 The third argument of `split-window' has been renamed to SIDE and can be
1509 set to any of the values 'below, 'right, 'above, or 'left to make the
1510 new window appear on the corresponding side of the window that shall be
1511 split. Any other value of SIDE will cause `split-window' to split the
1512 window into two side-by-side windows as before.
1513
1514 *** Window resizing functions.
1515 A new standard function for resizing windows called `window-resize' has
1516 been introduced. This and all other functions for resizing windows no
1517 longer delete any windows when they become too small.
1518
1519 *** Deleting the selected window now selects the most recently selected
1520 live window on that frame instead.
1521
1522 *** `adjust-window-trailing-edge' adjustments.
1523 `adjust-window-trailing-edge' can now deal with fixed-size windows and
1524 is able to resize other windows if a window adjacent to the trailing
1525 edge cannot be shrunk any more. This makes its behavior more similar to
1526 that of Emacs 21 without compromising, however, its inability to delete
1527 windows which was introduced in Emacs 22.
1528
1529 *** Window-local buffer lists.
1530 Windows now have local buffer lists. This means that removing a buffer
1531 from display in a window will preferably show the buffer previously
1532 shown in that window with its previous window-start and window-point
1533 positions. This also means that the same buffer may be automatically
1534 shown twice even if it already appears in another window.
1535
1536 *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW,
1537 which if non-nil requires the buffer to be displayed in the currently
1538 selected window, signaling an error otherwise. If nil, another window
1539 can be used, e.g. if the selected one is strongly dedicated.
1540
1541 *** `split-window-vertically' and `split-window-horizontally' renamed
1542 to `split-window-below' and `split-window-right' respectively.
1543 The old names are kept as aliases.
1544
1545 *** Display actions
1546
1547 **** The second arg to `display-buffer' and `pop-to-buffer' is now
1548 named ACTION, and takes a display action of the same form as
1549 `display-buffer-base-action' (see Changes, above). A non-nil,
1550 non-list value is treated specially, as the old meaning.
1551
1552 **** New variable `display-buffer-overriding-action'.
1553
1554 **** The procedure of `display-buffer' etc. to choose a window is
1555 determined by combining `display-buffer-overriding-action',
1556 `display-buffer-alist', the ACTION arg, `display-buffer-base-action',
1557 and `display-buffer-fallback-action'. The second and fourth of these
1558 are user-customizable variables.
1559
1560 See the docstring of `display-buffer' for details.
1561
1562 *** New functions `window-state-get' and `window-state-put'.
1563 These functions allow to save and restore the state of an arbitrary
1564 frame or window as an Elisp object.
1565
1566 ** Completion
1567
1568 *** New variable `completion-extra-properties' used to specify extra
1569 properties of the current completion:
1570 - :annotate-function, same as the old completion-annotate-function.
1571 - :exit-function, function to call after completion took place.
1572
1573 *** Functions on `completion-at-point-functions' can return any of the
1574 properties valid for `completion-extra-properties'.
1575
1576 *** `completion-annotate-function' is obsolete.
1577
1578 *** New `metadata' method for completion tables. The metadata thus returned
1579 can specify various details of the data returned by `all-completions':
1580 - `category' is the kind of objects returned (e.g., `buffer', `file', ...),
1581 used to select a style in completion-category-overrides.
1582 - `annotation-function' to add annotations in *Completions*.
1583 - `display-sort-function' to specify how to sort entries in *Completions*.
1584 - `cycle-sort-function' to specify how to sort entries when cycling.
1585
1586 *** `minibuffer-local-filename-must-match-map' is not used any more.
1587 Instead, the bindings in `minibuffer-local-filename-completion-map'
1588 are combined with `minibuffer-local-must-match-map'.
1589
1590 *** New variable `completing-read-function' allows overriding the
1591 behavior of `completing-read'.
1592
1593 ** `glyphless-char-display' can now distinguish between graphical and
1594 text terminal display, via a char-table entry that is a cons cell.
1595
1596 ** `pre-command-hook'/`post-command-hook' are not reset to nil on error.
1597 Instead, the offending function is removed.
1598
1599 ** New hook types
1600
1601 *** New function `run-hook-wrapped' for running an abnormal hook by
1602 passing the hook functions as arguments to a "wrapping" function.
1603 Like `run-hook-with-args-until-success', it stops at the first
1604 non-nil return value.
1605
1606 *** New macro `with-wrapper-hook' for running an abnormal hook as a
1607 set of "wrapping" filters, similar to around advice.
1608 (A version of this macro was actually added in Emacs 23.2 but was not
1609 advertised at the time.)
1610
1611 ** Debugger changes
1612
1613 *** New macro `condition-case-unless-debug' (this was actually added in
1614 Emacs 23.1 as condition-case-no-debug, but not advertised)
1615
1616 *** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised.
1617
1618 *** Variable `stack-trace-on-error' removed.
1619
1620 *** The debugger can now "continue" from an error, which means it will
1621 jump to the error handler as if the debugger had not been invoked
1622 instead of jumping all the way to the top-level.
1623
1624 *** Set `debug-on-event' to enter the debugger on events like SIGUSR1.
1625 This can be useful when `inhibit-quit' is set.
1626
1627 ** The new function `server-eval-at' allows evaluation of Lisp forms on
1628 named Emacs server instances.
1629
1630 ** `call-process' and `call-process-region' allow a `(:file "file")' spec
1631 to redirect STDOUT to a file.
1632
1633 ** The function `format-time-string' now supports the %N directive,
1634 for higher-resolution time stamps.
1635
1636 ** New input reading functions
1637
1638 *** New function `read-char-choice' reads a restricted set of
1639 characters, discarding any inputs not inside the set.
1640
1641 *** The command `read-color' now requires a match for a color name
1642 or RGB triplet, instead of signaling an error if the user provides
1643 invalid input.
1644
1645 **** `facemenu-read-color' is now an alias for `read-color'.
1646
1647 ** `image-library-alist' is renamed to `dynamic-library-alist'.
1648 The variable is now used to load all kind of supported dynamic libraries,
1649 not just image libraries. The previous name is still available as an
1650 obsolete alias.
1651
1652 ** Syntax parsing changes
1653
1654 *** New variable `syntax-propertize-function'.
1655 This replaces `font-lock-syntactic-keywords' which is now obsolete.
1656 This allows syntax-table properties to be set independently from font-lock:
1657 just call syntax-propertize to make sure the text is propertized.
1658 Together with this new variable come a new hook
1659 syntax-propertize-extend-region-functions, as well as two helper functions:
1660 syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
1661 as-is; and syntax-propertize-rules which provides a new way to specify
1662 syntactic rules.
1663
1664 *** Syntax tables support a new "comment style c" additionally to style b.
1665
1666 ** New hook `post-self-insert-hook', run after `self-insert-command'.
1667
1668 ** frame-local variables cannot be let-bound any more.
1669
1670 ** Major and minor mode changes
1671
1672 *** `set-auto-mode' now respects mode: local variables at the end of files,
1673 as well as those in the -*- line.
1674
1675 *** `prog-mode' is a new major mode from which programming modes
1676 should be derived.
1677
1678 **** `prog-mode-hook' can be used to enable features for programming
1679 modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable
1680 on-the-fly spell checking for comments and strings.
1681
1682 *** New hook `change-major-mode-after-body-hook', run by
1683 `run-mode-hooks' just before any other mode hooks.
1684
1685 *** Enabled globalized minor modes can be disabled in specific major modes.
1686 If the global mode is global-FOO-mode, then run (FOO-mode -1) in the
1687 major mode's hook, where FOO-mode toggles the mode on a per-buffer basis.
1688
1689 *** `define-minor-mode' accepts new keywords :variable, :after-hook.
1690
1691 ** File-handling changes
1692
1693 *** `delete-file' and `delete-directory' now accept optional arg TRASH.
1694 Trashing is performed if TRASH and `delete-by-moving-to-trash' are
1695 both non-nil. Interactively, TRASH defaults to t, unless a prefix
1696 argument is supplied (see Trash changes, above).
1697
1698 *** New file predicates: `file-equal-p', `file-in-directory-p'.
1699
1700 ** Tool-bars can display separators.
1701 Tool-bar separators are handled like menu separators in menu-bar maps,
1702 i.e. via menu entries of the form `(menu-item "--")'.
1703
1704 ** Image API
1705
1706 *** Animated images support (currently animated gifs only).
1707
1708 **** `image-animated-p' returns non-nil if an image can be animated.
1709
1710 **** `image-animate' animates a supplied image spec.
1711
1712 **** `image-animate-timer' returns the timer object for an image that
1713 is being animated.
1714
1715 *** `image-extension-data' has been renamed to `image-metadata'.
1716 The old name is an obsolete alias to the new one.
1717
1718 *** Image mode can view any image type that ImageMagick supports.
1719 This requires Emacs to be built with ImageMagick support.
1720
1721 **** New function `imagemagick-types', defined if ImageMagick support
1722 is enabled, returns a list of image file extensions that your
1723 ImageMagick installation supports.
1724
1725 **** New function `imagemagick-register-types' enables ImageMagick
1726 image types in Image mode and in `create-image' and other helper
1727 functions.
1728
1729 **** New option `imagemagick-types-inhibit' excludes certain
1730 ImageMagick image types from `imagemagick-register-types'.
1731
1732 **** With ImageMagick support, there are extra Image mode commands to
1733 resize and rotate images: `image-transform-fit-to-height',
1734 `image-transform-fit-to-width', `image-transform-set-rotation', and
1735 `image-transform-set-scale'.
1736
1737 ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and
1738 passes it to the mail user agent function. This argument specifies an
1739 action for returning to the caller after finishing with the mail. For
1740 example, this is used by Rmail to optionally delete a mail window.
1741
1742 ** XML and HTML parsing
1743 If Emacs is compiled with libxml2 support, there are two new
1744 functions: `libxml-parse-html-region' (which parses "real world" HTML)
1745 and `libxml-parse-xml-region' (which parses XML). Both return an
1746 Emacs Lisp parse tree.
1747
1748 ** Networking and encryption changes
1749
1750 *** `open-network-stream' can now be used to open an encrypted stream.
1751 It now accepts an optional `:type' parameter for initiating a TLS
1752 connection, directly or via STARTTLS. To do STARTTLS, additional
1753 parameters (`:end-of-command', `:success', `:capabilities-command')
1754 must also be supplied.
1755
1756 *** New library gnutls.el.
1757 The new function `gnutls-available-p' returns non-nil if Emacs is
1758 built with GnuTLS support. The main entry points are
1759 `open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use
1760 these functions through `open-network-stream', because that can
1761 upgrade connections through STARTTLS opportunistically or use plain
1762 SSL, depending on your needs. For debugging, set `gnutls-log-level'
1763 greater than 0.
1764
1765 *** New primitive `secure-hash' that supports many secure hash algorithms:
1766 md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library
1767 sha1.el has been removed. The `sha1' feature is provided by default.
1768
1769 ** Isearch
1770
1771 *** New hook `isearch-update-post-hook' that runs in `isearch-update'.
1772
1773 ** Progress reporters can now "spin".
1774 The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
1775 now be nil, or omitted. This makes a "non-numeric" reporter. Each
1776 time you call `progress-reporter-update' on that progress reporter,
1777 with a nil or omitted VALUE argument, the reporter message is
1778 displayed with a "spinning bar".
1779
1780 ** New variable `revert-buffer-in-progress-p' is true while a buffer is
1781 being reverted, even if the buffer has a local `revert-buffer-function'.
1782
1783 ** New variables `delayed-warnings-list' and `delayed-warnings-hook'.
1784 If delayed-warnings-list is non-nil, the command loop calls
1785 `delayed-warnings-hook' after `post-command-hook'. At present, this
1786 is only used by Emacs on some platforms to display warnings during
1787 startup, which might otherwise not be noticed. This uses the
1788 functions `display-delayed-warnings' and `collapse-delayed-warnings'.
1789
1790 ** rx.el has a new `group-n' construct for explicitly numbered groups.
1791
1792 ** New function `make-composed-keymap' that constructs a new keymap
1793 from multiple input maps. You can use this to make a keymap that
1794 inherits from multiple maps, eg:
1795 (set-keymap-parent newmap (make-composed-keymap othermap parent))
1796
1797 ** New function `string-prefix-p'.
1798 (This was actually added in Emacs 23.2 but was not advertised at the time.)
1799
1800 ** New reader macro ## that stands for the empty symbol.
1801 This means that the empty symbol can now be read back. Also, #: by itself
1802 (when not immediately followed by a possible symbol character) stands for
1803 an empty uninterned symbol.
1804
1805 ** New math functions `isnan', `copysign', `frexp', `ldexp'.
1806
1807 ** The following functions and variables are obsolete:
1808
1809 *** `tooltip-use-echo-area' is obsolete.
1810 Rather than setting this to t, disable Tooltip mode instead.
1811
1812 *** buffer-substring-filters is obsolete.
1813 Use `filter-buffer-substring-functions' instead.
1814
1815 *** `byte-compile-disable-print-circle' is obsolete.
1816
1817 *** `deferred-action-list' and `deferred-action-function' are obsolete.
1818 Use `post-command-hook' instead.
1819
1820 *** `font-lock-maximum-size' is obsolete.
1821
1822 \f
1823 * Changes in Emacs 24.1 on non-free operating systems
1824
1825 ** On MS Windows, Emacs warns when using the obsolete init file _emacs,
1826 and also when HOME is set to C:\ by default.
1827
1828 ** New configure.bat options
1829
1830 *** --enable-checking builds Emacs with extra runtime checks.
1831
1832 *** --distfiles specifies files to be included in binary distribution.
1833
1834 *** --without-gnutls disables automatic GnuTLS detection.
1835
1836 *** --lib for general library linkage, works with the USER_LIBS build variable.
1837
1838 ** New make target `dist' to create binary distribution for MS Windows.
1839
1840 ** The Lisp function `w32-default-color-map' is now obsolete.
1841 (It is only used internally in the Emacs C code.)
1842
1843 ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but
1844 reappear on mouse-over. (Requires OS X 10.6 or later.)
1845
1846 ** On Mac OS X, dragging a file into Emacs visits the file, like on
1847 other platforms, rather than inserting its contents into the buffer.
