349*** New functions `frame-scroll-bar-height' and
350 `window-scroll-bar-height' return the height of horizontal scroll
351 bars on a specific frame or window.
352*** `set-window-scroll-bars' now accepts five parameters where the last
353 two specify height and type of the window's horizontal scroll bar.
354*** `window-scroll-bars' now returns type and sizes of horizontal scroll
355 bars too.
356*** New buffer-local variables `horizontal-scroll-bar' and
357 `scroll-bar-height'.
358
359** The height of a frame's menu and tool bar are no more counted in the
360frame's text height. This means that the text height stands only for
361the height of the frame's root window plus that of the echo area (if
362present). This was already the behavior for frames with external tool
363and menu bars (like in the Gtk builds) but has now been extended to all
364builds.
365
366** Frames now do not necessarily preserve the number of columns or lines
367they display when setting default font, menu bar, fringe width, or
368scroll bars. In particular, maximized and fullscreen frames are
369conceptually never resized if such settings change. For fullheight and
370fullwidth frames, the behavior may depend on the toolkit used.
371*** New option `frame-inhibit-implied-resize' if non-nil, means that
372 setting default font, menu bar, fringe width, or scroll bars of a
373 specific frame does not resize that frame in order to preserve the
374 number of columns or lines it displays.

224 383
225 384** Building Emacs on OSX with Coca (--with-ns) now requires 10.6 or newer.
226* Installation Changes in Emacs 24.4 385PowerPC on OSX is not supported.
227
228** Emacs can now be compiled with ACL (access control list) support.
229This happens by default if a suitable support library is found at
230build time, like libacl on GNU/Linux. To prevent this, use the
231configure option `--disable-acl'. See below for the features this provides.
232
233** Emacs can now be compiled with file notification support.
234This happens by default if a suitable system library is found at
235build time. To prevent this, use the configure option
236`--without-file-notification'. See below for file-notify features.
237This feature is not available for the Nextstep port.
238
239** Emacs can now be compiled with zlib support.
240This happens by default if zlib is present, which it normally is.
241To prevent this, use the configure option `--without-zlib'.
242This provides the function `zlib-decompress-region'; see below for details.
243
244** The configure option `--without-compress-info' has been generalized,
245and renamed to `--without-compress-install'. It now prevents compression
246of _any_ files during installation.
247
248** The configure option `--with-crt-dir' has been removed.
249It is no longer needed, as the crt*.o files are no longer linked specially.
250
251** Directories passed to configure option `--enable-locallisppath' are
252no longer created during installation.
253
254** Emacs for Nextstep (Mac OS X, GNUstep) can be built with ImageMagick support.
255This requires pkg-config to be available at build time.
256
257
258* Startup Changes in Emacs 24.4
259
260** When initializing `load-path', an empty element in the EMACSLOADPATH
261environment variable (either leading, e.g., ":/foo"; trailing, e.g.,
262"/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default
263load-path (the one that would have been used if EMACSLOADPATH was unset).
264This makes it easier to _extend_ the load-path via EMACSLOADPATH
265(previously, EMACSLOADPATH had to specify the complete load-path,
266including the defaults). (In older versions of Emacs, an empty element
267was replaced by ".", so use an explicit "." now if that is what you want.)
268
269** The -L option, which normally prepends its argument to load-path,
270will instead append, if the argument begins with `:' (or `;' on MS Windows;
271i.e., `path-separator').
272
273** If you use either site-load.el or site-init.el to customize the dumped
274Emacs executable, any changes to `load-path' that these files make
275will no longer be present after dumping. To affect a permanent change
276to `load-path', use the `--enable-locallisppath' option of `configure'.
277
278** The user option `initial-buffer-choice' can now specify a function
279to set up the initial buffer.
280
281
282* Changes in Emacs 24.4
283
284** Support for ACLs (access control lists).
285This requires a suitable support library to be found at build time.
286On GNU/Linux, the POSIX ACL interface is used via libacl.
287On MS-Windows, the NT Security APIs are used to emulate the POSIX interface.
288ACLs are extended file attributes, used e.g. for finer-grained permissions.
289
290*** Emacs preserves the ACL entries of files when backing up.
291
292*** New functions `file-acl' and `set-file-acl' get and set file ACLs.
293
294** Support for menus on text-mode terminals.
295If the terminal supports a mouse, clicking on the menu bar, or on
296sensitive portions of the mode line or header line, will drop down the
297menu defined at that position. Likewise, clicking C-mouse-1, C-mouse-2, or
298C-mouse-3 on the text area will pop up the menus defined for those locations.
299
300If the text terminal does not support a mouse, you can activate the
301first menu-bar menu by typing F10, which invokes `menu-bar-open'.
302
303If you want the previous behavior, where F10 invoked `tmm-menubar',
304customize the option `tty-menu-open-use-tmm' to a non-nil value.
305(Typing M-` always invokes `tmm-menubar', even if `tty-menu-open-use-tmm'
306is nil.)
307
308** New option `load-prefer-newer' affects how the `load' function chooses
309the file to load. If this is non-nil, then when both .el and .elc
310versions of a file exist, and the caller did not explicitly specify
311which one to load, then the newer file is loaded. The default, nil,
312means to always load the .elc file.
313
314** Multi-monitor support
315
316*** New functions `display-monitor-attributes-list' and
317`frame-monitor-attributes' can be used to obtain information about
318each physical monitor on multi-monitor setups.
319
320*** The functions `display-pixel-width' and `display-pixel-height' now
321behave consistently among the platforms: they return the pixel width
322or height for all physical monitors associated with the given display
323as if they were on X. To get information for each physical
324monitor, use the new functions above. Similar notes also apply to
325`x-display-pixel-width', `x-display-pixel-height', `display-mm-width',
326`display-mm-height', `x-display-mm-width', and `x-display-mm-height'.
327
328** New function `zlib-decompress-region', which decompresses gzip- and
329zlib-format compressed data using built-in zlib support (if available).
330
331** The *Messages* buffer is created in `messages-buffer-mode',
332a new major mode, with read-only status. Any code that might create
333the *Messages* buffer should call the function `messages-buffer' to do
334so and set up the mode.
335
336** The cursor stops blinking after 10 blinks (by default) on X and Nextstep.
337You can change the default by customizing `blink-cursor-blinks'.
338
339** In keymaps where SPC scrolls forward, S-SPC now scrolls backward.
340This affects View mode, etc.
341
342** The default value of `make-backup-file-name-function' is no longer nil.
343Instead it defaults to a function that does what the nil value used to.
344
345** Help
346
347*** The command `apropos-variable' is renamed to `apropos-user-option'.
348`apropos-user-option' shows all user options, while `apropos-variable'
349shows all variables. When called with a universal prefix argument,
350the two commands swap their behaviors. When `apropos-do-all' is
351non-nil, they output the same results.
352
353*** The key `?' now describes prefix bindings, like `C-h'.
354
355*** The command `describe-function' has been extended for EIEIO.
356Running it on constructors will show a full description of the
357generated class. For generic functions, it will show all
358implementations together with links to the source. The old commands
359`describe-class', `describe-constructor' and `describe-generic' were
360removed.
361
362*** The function `quail-help' is no longer an interactive command.
363Use `C-h C-\' (`describe-input-method') instead.
364
365** Frame and window handling
366
367*** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized',
368bound to <f11> and M-<f10>, respectively.
369
370*** New hooks `focus-in-hook', `focus-out-hook'.
371These are normal hooks run when an Emacs frame gains or loses input focus.
372
373*** The function `window-in-direction' now takes additional arguments
374for specifying a reference point, wrapping the selection around frame
375borders, and specifying ways to select the minibuffer window.
376
377*** Emacs can now change frame sizes in units of pixels, rather than
378text rows or columns. When maximizing a frame or making it fullscreen,
379remaining extra pixels are no longer given to the minibuffer, the rightmost
380fringe, or other unusable space, but are distributed among the text
381areas of the frame's windows. If the new option `frame-resize-pixelwise'
382is non-nil, all frame size changes happen pixelwise and set the
383corresponding size hints for the window manager.
384
385*** Emacs can now change window sizes in units of pixels.
386Mouse-dragging a mode line or window divider now changes the size of
387adjacent windows pixelwise. If the new option `window-resize-pixelwise'
388is non-nil, functions like `balance-windows-area' and `fit-window-to-buffer'
389resize windows pixelwise. Most functions for changing or accessing
390window sizes now have an additional argument that allows changes to apply,
391or values to be returned, in pixels instead of lines/columns.
392
393*** The functions `window-body-height' and `window-body-width' now never
394count partially visible lines or columns if called with a nil PIXELWISE
395argument.
396
397*** Emacs can now draw dividers between adjacent windows. To put
398dividers between side-by-side/vertically stacked windows customize the
399frame parameters `right-divider-width' and `bottom-divider-width' to
400some positive integer. You can drag dividers with the mouse (they show
401a corresponding cursor when the mouse hovers over them). You can change
402the appearance of dividers by customizing the faces `window-divider',
403`window-divider-first-pixel', and `window-divider-last-pixel'. The last
404two are useful to provide a 3D effect, or to better distinguish dividers
405from surrounding display objects.
406
407*** New functions to return the pixel sizes of window components, namely
408`window-scroll-bar-width', `window-mode-line-height',
409`window-header-line-height', `window-right-divider-width', and
410`window-bottom-divider-width'.
411
412*** The new function `window-text-pixel-size' returns the size of the
413text of a window's buffer in pixels. This allows functions like
414`fit-frame-to-buffer' and `fit-window-to-buffer' to accurately fit a
415window to its buffer as it will be displayed.
416
417*** `fit-window-to-buffer' can now resize windows in both dimensions.
418This behavior is controlled by the new option
419`fit-window-to-buffer-horizontally'. The new option
420`fit-frame-to-buffer' allows you to fit the window's frame to its buffer.
421
422*** `fit-frame-to-buffer' now fits frames in both dimensions. The new
423options `fit-frame-to-buffer-margins' and `fit-frame-to-buffer-sizes'
424control the size of the frame and its position on screen.
425
426*** Temp Buffer Resize Mode can now adjust the height and width of
427windows and frames. The new option `temp-buffer-max-width' allows you to
428control the width of temporary buffer windows. Moreover, if the new
429option `fit-frame-to-buffer' is non-nil and the buffer appears in the
430root window of a frame, Temp Buffer Resize Mode will try to adjust the
431width and/or height of the frame.
432
433*** `split-window' is now a non-interactive function, not a command.
434As a command, it was a special case of `C-x 2' (`split-window-below'),
435and as such superfluous. After being reimplemented in Lisp, its
436interactive form was mistakenly retained.
437
438*** The functions `window-size' and `window-total-size' now have an
439optional argument to return a rounded size value.
440
441*** `window-state-put' now allows you to put a window state into internal
442windows too.
443
444*** New option `scroll-bar-adjust-thumb-portion'.
445Available only on X, this option allows you to control over-scrolling
446using the scroll bar (i.e., dragging the thumb down even when the end
447of the buffer is visible).
448
449*** New display actions functions for `display-buffer':
450
451**** `display-buffer-in-previous-window' displays a buffer in a window
452previously showing that buffer.
453
454**** `display-buffer-at-bottom' chooses or creates a window at the
455bottom of the selected frame.
456
457**** `display-buffer-no-window' to not display the buffer in a window.
458
459*** New display action alist entry `allow-no-window' to indicate the
460caller of `display-buffer' is ready to handle the case of not displaying
461the buffer in a window.
462
463** Lisp evaluation
464
465*** `eval-defun' on an already defined defcustom calls the :set function,
466if there is one.
467
468*** The commands `eval-expression' (`M-:'), `eval-last-sexp' (`C-x C-e'),
469and `eval-print-last-sexp' (`C-j' in Lisp Interaction mode) can take a
470zero prefix argument. This disables truncation of lists in the output,
471equivalent to setting `(eval-expression-)print-length' and
472`(eval-expression-)print-level' to nil. Additionally, it causes integers
473to be printed in other formats (octal, hexadecimal, and character).
474
475*** New hook `eval-expression-minibuffer-setup-hook' run by
476`eval-expression' on entering the minibuffer.
477
478** `cache-long-line-scans' is now non-nil, and renamed to `cache-long-scans',
479because it affects caching of paragraph scanning results as well.
480There is no reason to set this to nil except for debugging purposes.
481
482** `emacs-bzr-version' has been renamed to `emacs-repository-version',
483and works for git too, if you fetch the repository notes.
484
485** The default value of `comment-use-global-state' is now t,
486and this variable has been marked obsolete.
487
488** `write-region-inhibit-fsync' now defaults to t in batch mode.
489
490** The option `set-mark-default-inactive' has been deleted.
491This unfinished feature was introduced by accident in Emacs 23.1;
492simply disabling Transient Mark mode does the same thing.
493
494
495* Editing Changes in Emacs 24.4
496
497** Indentation
498
499*** `electric-indent-mode' is now enabled by default.
500Typing RET reindents the current line and indents the new line.
501`C-j' inserts a newline but does not indent. In some programming modes,
502additional characters are electric (eg `{').
503
504*** New buffer-local `electric-indent-local-mode'.
505
506*** The behavior of `C-x TAB' (`indent-rigidly') has changed.
507When invoked without a prefix argument, it now activates a transient
508mode in which typing <left>, <right>, <S-left>, and <S-right> adjusts
509the text indentation in the region. Typing any other key resumes
510normal editing behavior.
511
512*** `tab-stop-list' is now implicitly extended to infinity by repeating
513the last step. Its default value is changed to nil, which means a tab
514stop every `tab-width' columns.
515
516** Uniquify is enabled by default, with `post-forward-angle-brackets' style.
517In other words, if you visit two files that have the same base name,
518then rather than creating buffers basename and basename<2>,
519Emacs uses basename<dirA> and basename<dirB>. To change this,
520customize `uniquify-buffer-name-style'. Set it to nil for the old behavior.
521
522** New command `C-x SPC' (`rectangle-mark-mode') makes a rectangular region.
523Most commands are still unaware of it, but kill/yank do work on the rectangle.
524
525** New option `visual-order-cursor-movement'.
526If this is non-nil, cursor motion with arrow keys will follow the
527visual order of characters on the screen: <left> always moves to the
528left, <right> always moves to the right, disregarding the surrounding
529bidirectional context.
530
531** New command `delete-duplicate-lines'.
532This searches the region for identical lines, and removes all but one
533copy of each repeated line. The lines need not be sorted.
534
535** New command `cycle-spacing' acts like a smarter `just-one-space'.
536When called in succession, it cycles between spacing conventions:
537one space, no spaces, original spacing.
538
539** `blink-matching-paren' now only highlights the matching open-paren
540by default, instead of moving the cursor. Set this variable to `jump' to
541restore the old behavior.
542
543** The new function `fill-single-char-nobreak-p' can stop fill from breaking
544a line after a one-letter word, which is an error in some typographical
545conventions. To use it, add it to the `fill-nobreak-predicate' hook.
546
547** Registers
548
549*** All interactive commands that read a register (`copy-to-register', etc.)
550now display a temporary window after `register-preview-delay' seconds
551that summarizes existing registers. To disable this, set that option to nil.
552Interactive commands that read registers and want to make use of this
553should use `register-read-with-preview' to read register names.
554
555*** New command `frameset-to-register' bound to `C-x r f', replacing
556`frame-configuration-to-register'. It offers similar functionality,
557plus enhancements like the ability to restore deleted frames.
558(`frame-configuration-to-register' still exists, but no longer has a
559key binding.)
560
561*** New command `C-x C-k x' (`kmacro-to-register') stores keyboard
562macros in registers.
563
564
565* Changes in Specialized Modes and Packages in Emacs 24.4
566
567** Backtrace and debugger
568
569*** New Lisp debugger command `v' (`debugger-toggle-locals') toggles the
570display of local variables of the current stack frame.
571
572*** The Lisp debugger's `e' command (`debugger-eval-expression') now includes
573the lexical environment when evaluating the code in the context at point
574(and so allows you to access lexical variables).
575
576*** New minor mode `jit-lock-debug-mode' helps you debug code run via JIT Lock.
577
578** Battery information can now be retrieved from BSD's `apm' utility.
579
580** In the Buffer Menu, `M-s a C-o' shows matches for a regexp in marked buffers.
581
582** Calc
583
584*** Calc by default now uses the Gregorian calendar for all dates, and
585uses January 1, 1 AD as its day number 1. Previously Calc used the
586Julian calendar for dates before September 14, 1752, and it used
587December 31, 1 BC as its day number 1; the new scheme is more
588consistent with Calendar's calendrical system and day numbering.
589
590*** The new option `calc-gregorian-switch' lets you configure if
591(and when) Calc switches from the Julian to the Gregorian calendar.
592
593*** Support for ISO 8601 dates.
594
595** Calendar and Diary
596
597*** New faces `calendar-weekday-header', `calendar-weekend-header',
598and `calendar-month-header'.
599
600*** New option `calendar-day-header-array'.
601
602*** New variable `diary-from-outlook-function', used by the command
603`diary-from-outlook'.
604
605*** The variable `calendar-font-lock-keywords' is obsolete.
606
607** CEDET
608
609*** EDE
610
611**** The cpp-root project now supports executing a compile command.
612It can be set through the new :compile-command slot or the
613buffer-local variable `compile-command'.
614
615**** Better selection of include directories for the 'linux' project.
616Include directories now support out-of-tree build directories and
617target architecture auto-detection.
618
619*** Semantic
620
621**** Improved detection of used namespaces in current scope in C++.
622
623**** Parsing of default values for variables and function arguments in C/C++.
624They are also displayed by the summarize feature in the mode line.
625
626**** Improved parsing of function pointers in C/C++.
627This also includes parsing of function pointers as function arguments.
628
629**** Parsing of C/C++ preprocessor macros that open new scope.
630For example, this enables parsing of macros that open new namespaces.
631
632**** Support for 'this' pointer in inline member functions in C++.
633
634** CFEngine mode
635
636*** Support for completion, ElDoc, and Flycheck has been added.
637
638*** The current CFEngine syntax is parsed from "cf-promises -s json".
639There is a fallback syntax available if you don't have cf-promises or
640if your version doesn't support that option. See option `cfengine-cf-promises'.
641
642** cl-lib
643
644*** New macro `cl-tagbody'.
645This executes statements while allowing for control transfer to labels.
646
647*** letf is now just an alias for cl-letf.
648
649** CUA mode
650
651*** CUA mode now uses `delete-selection-mode' and `shift-select-mode'.
652Hence, you can now enable it independently from those modes, and from
653`transient-mark-mode'.
654
655*** `cua-highlight-region-shift-only' is now obsolete.
656You can disable `transient-mark-mode' to get the same result.
657
658*** CUA's rectangles can now be used without CUA by calling the command
659`cua-rectangle-mark-mode'.
660
661** Delete Selection mode can now be used without Transient Mark mode.
662
663** Desktop
664
665*** `desktop-save-mode' by default now auto-saves an existing desktop file
666after `desktop-auto-save-timeout'. To disable this, customize that option
667to nil (or zero).
668
669*** Desktop now saves and restores the frame/window configuration.
670To disable this, set `desktop-restore-frames' to nil.
671See also related options `desktop-restore-reuses-frames',
672`desktop-restore-in-current-display', and `desktop-restore-forces-onscreen'.
673
674** New Dired minor mode `dired-hide-details-mode' toggles whether details,
675such as file ownership or permissions, are visible in Dired buffers.
676See the new options `dired-hide-details-hide-symlink-targets' and
677`dired-hide-details-hide-information-lines' for customizing what to hide.
678
679** You can enable ElDoc inside the `eval-expression' minibuffer with:
680 (add-hook 'eval-expression-minibuffer-setup-hook 'eldoc-mode)
681The results display in the mode line.
682
683** Electric Pair mode
684
685*** New option `electric-pair-preserve-balance', enabled by default.
686If non-nil, pairing/skipping only kicks in when that help the balance
687of parentheses and quotes; i.e., the buffer should end up at least as
688balanced as before.
689
690You can further control this behavior by adjusting the predicates
691stored in `electric-pair-inhibit-predicate' and `electric-pair-skip-self'.
692
693*** New option `electric-pair-delete-adjacent-pairs', enabled by default.
694In `electric-pair-mode', the commands `backward-delete-char' and
695`backward-delete-char-untabify' are now bound to electric variants
696that delete the closer when invoked between adjacent pairs.
697
698*** New option `electric-pair-open-newline-between-pairs', enabled by default.
699In `electric-pair-mode', inserting a newline between adjacent pairs
700opens an extra newline after point, which is indented if
701`electric-indent-mode' is also set.
702
703*** New option `electric-pair-skip-whitespace', enabled by default.
704This controls if skipping over closing delimiters should jump over any
705whitespace slack. Setting it to `chomp' makes it delete this
706whitespace. See also the variable `electric-pair-skip-whitespace-chars'.
707
708*** New variables control the pairing in strings and comments.
709You can customize `electric-pair-text-pairs' and
710`electric-pair-text-syntax-table' to tweak pairing behavior inside
711strings and comments.
712
713** New EPA option `epa-mail-aliases'.
714You can set this to a list of email address aliases that `epa-mail-encrypt'
715should use to find keys.
716
717** New ERC option `erc-accidental-paste-threshold-seconds'.
718If set to a number, this can be used to avoid accidentally pasting large
719amounts of data into the ERC input.
720
721** New ERT macro `skip-unless' allows skipping ERT tests.
722
723** Eshell
724
725*** `eshell' now supports visual subcommands and options.
726Eshell has been able to handle "visual" commands (interactive,
727non-line oriented commands such as top that require display
728capabilities not provided by eshell) by running them in an Emacs
729terminal emulator. See `eshell-visual-commands'.
730
731This feature has been extended to subcommands and options that make a
732usually line-oriented command a visual command. Typical examples are
733"git log" and "git <command> --help", which display their output in a
734pager by default. See `eshell-visual-subcommands' and `eshell-visual-options'.
735
736*** New Eshell-Tramp module.
737External su and sudo commands are now the default; the internal,
738Tramp-using variants can still be used by enabling the eshell-tramp module.
739
740** New F90 mode option `f90-smart-end-names'.
741
742** New option `gnutls-verify-error', if non-nil, means that Emacs
743should reject SSL/TLS certificates that GnuTLS determines as invalid.
744(This option defaults to nil at present, but this is expected to change
745in a future release.)
746
747** Hi-Lock
748
749*** New global command `M-s h .' (`highlight-symbol-at-point') highlights
750the symbol near point.
751
752*** New option `hi-lock-auto-select-face'. When non-nil, hi-lock commands
753will cycle through faces in `hi-lock-face-defaults' without prompting.
754
755** Icomplete is now more similar to Ido.
756
757*** Icomplete by default now applies to all forms of minibuffer completion.
758The variable `icomplete-with-completion-tables' (now a user option)
759controls this. To restore the old behavior, set it back to
760'(internal-complete-buffer).
761
762*** You can navigate through and select completions using the keys
763from `icomplete-minibuffer-map'.
764
765*** The string that separates potential completions is now a customizable
766option (`icomplete-separator'). The default is " | " rather than ",".
767
768*** New face `icomplete-first-match'; and new options
769`icomplete-hide-common-prefix' and `icomplete-show-matches-on-no-input'.
770
771*** The option `icomplete-show-key-bindings' has been removed.
772
773** Ido
774
775*** An Ido user manual is now included.
776
777*** The option `ido-use-virtual-buffers' can now take the value `auto'.
778This means to use virtual buffers if the current ido input does not match
779an existing buffer.
780
781*** The variable `ido-decorations' can optionally have two new elements,
782which are the brackets to use around the sole remaining completion.
783
784** Image mode
785
786*** New commands `n' (`image-next-file') and `p' (`image-previous-file')
787visit the next image file and the previous image file in the same
788directory, respectively.
789
790*** New commands to show specific frames of multi-frame images.
791`f' (`image-next-frame') and `b' (`image-previous-frame') visit the
792next or previous frame. `F' (`image-goto-frame') shows a specific frame.
793
794*** New commands to speed up, slow down, or reverse animation.
795`a +' (`image-increase-speed') and `a -' (`image-decrease-speed') to
796speed up and slow down the animation. `a r' (`image-reverse-speed')
797to reverse it and `a 0' (`image-reset-speed') to reset it.
798
799*** The command `image-mode-fit-frame' deletes other windows.
800When toggling, it restores the frame's previous window configuration.
801It also has an optional frame argument, which can be used by Lisp
802callers to fit the image to a frame other than the selected frame.
803
804** New Imenu option `imenu-generic-skip-comments-and-strings'.
805
806** Info
807
808*** New Info face `info-index-match', used to highlight matches in index
809entries displayed by `Info-index-next', `Info-virtual-index' and
810`info-apropos'.
811
812*** The Info-edit command is obsolete. Editing Info nodes by hand
813has not been relevant for some time.
814
815** JS Mode
816
817*** New option `js-switch-indent-offset'.
818
819*** Better indentation of multiple-variable declarations.
820If a declaration spans several lines, variables on the following lines
821are lined up to the first one.
822
823*** Recognition and better indentation of continuations in array comprehensions.
824
825** MH-E has been updated to version 8.5 - see separate MH-E-NEWS file.
826
827** Octave mode
828
829*** Font locking for Texinfo comments and new keywords.
830
831*** Completion in Octave file buffers.
832
833*** ElDoc support.
834
835*** Jump to definition.
836
837*** Documentation lookup/search.
838
839** OPascal mode is the new name for Delphi mode
840
841*** All delphi-* variables and functions have been renamed to opascal-*.
842Obsolete aliases exist for those likely to have been used externally.
843
844*** The option `delphi-newline-always-indents' has been removed.
845Use `electric-indent-mode' instead.
846
847*** The TAB key runs the standard `indent-for-tab-command', not `delphi-tab'.
848
849** Package
850
851*** The package library now supports digital signing of packages.
852Maintainers of package archives should consider signing their packages
853to enhance security.
854
855**** If the user option `package-check-signature' is non-nil,
856Emacs tries to check package signatures at install time.
857The value `allow-unsigned' allows installation of unsigned packages.
858
859**** The user option `package-unsigned-archives' lists archives where
860Emacs will not try to check signatures.
861
862*** New option `package-pinned-packages'. This is useful if you have multiple
863archives enabled, with more than one offering a given package that you want.
864
865*** In the `list-packages' buffer, you can use `f' (`package-menu-filter')
866to filter the list of packages by a keyword.
867
868*** In the `describe-package' buffer, there are now buttons listing the
869keywords related to the package. Click on a button to see other packages
870related to that keyword.
871
872*** The format of `archive-contents' files, generated by package
873repositories, has changed to allow a new (fifth) element in the data
874vectors, containing an associative list with extra properties.
875(For example, `describe-package' uses the `:url' extra property to
876display a "Homepage" header.)
877
878** In Prolog mode, `prolog-use-smie' has been removed,
879along with the non-SMIE indentation code.
880
881** Python mode
882
883*** Out of the box support for CPython, iPython and readline based shells.
884**** `python-shell-completion-module-string-code' is no longer used.
885
886*** Automatic shell prompt detection. New user options:
887**** `python-shell-interpreter-interactive-arg'.
888**** `python-shell-prompt-detect-enabled'.
889**** `python-shell-prompt-detect-failure-warning'.
890**** `python-shell-prompt-input-regexps'.
891**** `python-shell-prompt-output-regexps'.
892
893*** Python shell support for remote hosts via tramp.
894
895*** Correct display of line numbers for code sent to the Python shell.
896
897** Remember
898
899*** The new command `remember-notes' creates a buffer that is saved on exit.
900You can use it as a more permanent *scratch* buffer.
901
902*** Remember can now store notes in separate files.
903To use this, add `remember-store-in-files' to the `remember-handler-functions'
904option. The files are saved in `remember-data-directory' using
905names specified by `remember-directory-file-name-format'.
906
907** Rmail
908
909*** Customize `rmail-mbox-format' to influence some minor aspects of
910how Rmail displays non-MIME messages.
911
912*** The `unrmail' command now converts from BABYL to mboxrd format,
913rather than mboxo. Customize `unrmail-mbox-format' to change this.
914
915** Ruby mode
916
917*** Improved syntax highlighting and indentation.
918
919*** New `electric-indent-mode' integration.
920
921*** New option `ruby-encoding-magic-comment-style'.
922
923*** New option `ruby-custom-encoding-magic-comment-template'.
924
925*** New option `ruby-align-to-stmt-keywords'.
926
927*** New option `ruby-align-chained-calls'.
928
929*** More Ruby file types have been added to `auto-mode-alist'.
930
931** Search and Replace
932
933*** New global command `M-s .' (`isearch-forward-symbol-at-point')
934starts a symbol (identifier) incremental search forward with the
935symbol found near point added to the search string initially.
936
937*** `C-x 8 RET' in Isearch mode reads a character by its Unicode name
938and adds it to the search string.
939
940*** `M-s i' in Isearch mode toggles whether search matches invisible text.
941
942*** `query-replace' skips invisible text when `search-invisible' is nil,
943and opens overlays with hidden text when `search-invisible' is `open'.
944
945*** A negative prefix argument of replacement commands replaces backward.
946`M-- M-%' replaces a string backward, `M-- C-M-%' replaces a regexp
947backward, `M-s w words M-- M-%' replaces a sequence of words backward.
948
949*** By default, prefix arguments do not now terminate Isearch mode.
950Set `isearch-allow-prefix' to nil to restore the old behavior.
951
952*** More Isearch commands accept prefix arguments, namely
953`isearch-printing-char', `isearch-quote-char', `isearch-yank-word',
954`isearch-yank-line'.
955
956*** Word search now matches whitespace at the beginning/end
957of the search string if it contains leading/trailing whitespace.
958In an incremental word search or when using a non-nil LAX argument
959of `word-search-regexp', the lax matching can also match part of
960the first word (in addition to the lax matching of the last word).
961The same rules are now applied to the symbol search, with the difference
962that it matches symbols, and non-symbol characters between symbols.
963
964** New SES command `ses-rename-cell' allows assignment of names to SES cells.
965
966** The shell.el option `explicit-bash-args' includes --noediting by default.
967All non-ancient Bash versions support this option.
968
969** Shell Script mode
970
971*** The SMIE indentation engine is now used by default - see `sh-use-smie'.
972
973*** `sh-mode' now has its own setting for `add-log-current-defun-function'.
974
975** SMIE
976
977*** You can customize the SMIE indentation of a mode via `smie-config'.
978The command `smie-config-guess' can help you derive the appropriate
979indentation settings, if you provide it with an indented sample file.
980Use `smie-config-save' to save the result.
981
982*** You can customize the SMIE indentation of a file by adding an entry to
983the file's local variables of the form: `eval: (smie-config-local '(RULES))'.
984
985*** New commands `smie-config-show-indent' and `smie-config-set-indent'.
986
987** SQL mode
988
989*** Improved login monitoring and appropriate response to login failures.
990New variable `sql-login-delay' defines maximum wait time for a connection.
991
992*** Oracle support.
993SQL*Plus script placeholders are properly highlighted and identified
994in `sql-placeholders-filter'. When starting SQL*Plus, `sql-oracle-options'
995are passed before the logon parameter, as required. The default now
996includes `-L', to limit the number of logon attempts per invocation.
997
998** New Term mode option `term-suppress-hard-newline'.
999
1000** Todo mode has been rewritten and enhanced.
1001The Todo mode user manual describes all commands and most user
1002options. To support some of these features, a new file format is
1003used, which is incompatible with the old format; however, you can
1004convert old todo and done item files to the new format on initializing
1005the first new todo file, or at any later time with the provided
1006conversion command. The previous version of todo-mode.el has been
1007renamed to otodo-mode.el and is now obsolete. New features include:
1008
1009*** Support for multiple todo files and archive files of done items.
1010
1011*** Renaming, reordering, moving, merging, and deleting categories.
1012
1013*** Sortable tabular summaries of categories and the item types they contain.
1014
1015*** Cross-category lists of items filtered by specific criteria.
1016
1017*** More fine-grained interaction with the Emacs diary, by being able to
1018decide for each todo item whether it appears in the Fancy Diary display.
1019
1020*** Highly flexible new item insertion and item editing.
1021
1022*** Moving items between categories, storing done items in their category
1023or in archive files, undoing or unarchiving done items.
1024
1025*** Reprioritizing items by inputting a numerical priority.
1026
1027*** Extensive customizability of operation and display, including many faces.
1028
1029** Trace
1030
1031*** `trace-function' and `trace-function-background' no longer prompt for
1032the output buffer. Unless you use a prefix argument, they output to
1033`trace-buffer'.
1034
1035*** With a prefix argument, `trace-function' and `trace-function-background'
1036will prompt for a "context". This is a Lisp expression, whose value at the
1037time the function is entered/exited is printed along with the function's
1038name and arguments.
1039
1040** Tramp
1041
1042*** New connection method "adb", which allows to access Android
1043devices by the Android Debug Bridge. The variable `tramp-adb-program'
1044can be used to adapt the path of the "adb" program, if needed.
1045
1046*** Handlers for `file-acl' and `set-file-acl' for remote machines
1047that support POSIX ACLs.
1048
1049*** Handlers for `file-notify-add-watch' and `file-notify-rm-watch'
1050for remote machines that support filesystem notifications.
1051
1052*** The experimental url syntax for remote file names has been removed.
1053
1054*** The connection methods "plink1", "ssh1", "ssh2", "scp1", "scp2",
1055"scpc" and "rsyncc" are discontinued. The ssh option
1056"ControlMaster=auto" is set automatically in all ssh-based methods,
1057when possible. See `tramp-use-ssh-controlmaster-options'.
1058
1059** New URL command `url-cookie-list' displays the current cookies,
1060and allows you to interactively remove cookies.
1061
1062** VC and related modes
1063
1064*** In VC directory mode, `D' displays diffs between VC-controlled
1065whole tree revisions.
1066
1067*** In VC directory mode, `L' lists the change log for the current VC
1068controlled tree in a window.
1069
1070*** In VC directory mode, `I' shows a log of changes that will be
1071received with a pull operation.
1072
1073*** `C-x v G' (globally) and `G' (in VC directory mode) ignores a file
1074under current version control system. When called with a prefix
1075argument, you can remove a file from the ignored file list.
1076
1077** VHDL mode
1078
1079*** New options: `vhdl-actual-generic-name', `vhdl-beautify-options'.
1080
1081*** New commands: `vhdl-fix-statement-region', `vhdl-fix-statement-buffer'.
1082
1083** The Woman commands `woman-default-faces' and `woman-monochrome-faces'
1084are obsolete. Customize the `woman-*' faces instead.
1085
1086** More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>.
1087Affected files:
1088~/.emacs.d/timelog replaces ~/.timelog
1089~/.emacs.d/vip replaces ~/.vip
1090~/.emacs.d/viper replaces ~/.viper
1091~/.emacs.d/ido.last replaces ~/.ido.last
1092~/.emacs.d/kkcrc replaces ~/.kkcrc
1093~/.emacs.d/quickurls replaces ~/.quickurls
1094~/.emacs.d/idlwave/ replaces ~/.idlwave/
1095~/.emacs.d/bdfcache.el replaces ~/.bdfcache.el
1096~/.emacs.d/places replaces ~/.emacs-places
1097~/.emacs.d/shadows replaces ~/.shadows
1098~/.emacs.d/shadow_todo replaces ~/.shadow_todo
1099~/.emacs.d/strokes replaces ~/.strokes
1100~/.emacs.d/notes replaces ~/.notes
1101~/.emacs.d/type-break replaces ~/.type-break
1102Also the following files used by the now obsolete otodo-mode.el:
1103~/.emacs.d/todo-do replaces ~/.todo-do
1104~/.emacs.d/todo-done replaces ~/.todo-done
1105~/.emacs.d/todo-top replaces ~/.todo-top
1106
1107** Obsolete packages
1108
1109*** iswitchb.el; use icomplete-mode.
1110
1111*** longlines.el; use visual-line-mode.
1112
1113*** meese.el.
1114
1115*** sup-mouse.el.
1116
1117*** terminal.el; use term.el instead.
1118
1119*** the old version of todo-mode.el (renamed to otodo-mode.el).
1120
1121*** xesam.el (owing to the cancellation of the XESAM project).
1122
1123*** yow.el; use fortune.el or cookie1.el instead.
1124
1125
1126* New Modes and Packages in Emacs 24.4
1127
1128** New package eww.el provides a built-in web browser.
1129This requires Emacs to have been compiled with libxml2 support.
1130
1131** New package nadvice.el offers lighter-weight advice facilities.
1132It is layered as:
1133
1134*** `add-function'/`remove-function', which can be used to add/remove code on
1135any function-carrying place, such as process filters or `<foo>-function' hooks.
1136
1137*** `advice-add'/`advice-remove' to add/remove a piece of advice on a named
1138function, much like `defadvice' does.
1139
1140** New package frameset.el provides a set of operations to save a frameset
1141(the state of all or a subset of the existing frames and windows, somewhat
1142similar to a frame configuration), both in-session and persistently, and
1143restore it at some point in the future.
1144
1145** New package filenotify.el provides an interface for file system
1146notifications. It requires that Emacs be compiled with one of the
1147low-level libraries gfilenotify.c, inotify.c or w32notify.c.
1148
1149** New minor modes `prettify-symbols-mode' and `global-prettify-symbols-mode'
1150display specified symbols as composed characters. E.g., in Emacs Lisp mode,
1151this replaces the string "lambda" with the Greek lambda character.
1152
1153** New minor mode `superword-mode', which overrides the default word motion
1154commands to treat "symbol_words" as a single word, similar to what
1155`subword-mode' does.
1156
1157
1158* Incompatible Lisp Changes in Emacs 24.4
1159
1160** The default file coding for Emacs Lisp files is now utf-8.
1161(See `file-coding-system-alist'.) In most cases, this change is
1162transparent, but files that contain unusual characters without
1163specifying an explicit coding system may fail to load with obscure
1164errors. You should either convert them to utf-8 or add an explicit
1165`coding:' cookie.
1166
1167** Default process filters and sentinels are not nil any more.
1168Instead they default to a function that does what the nil value used to do.
1169
1170** Overlay priority does not have to be nil or a non-negative integer.
1171Overlay priority can be other kinds of Lisp objects. We didn't yet
1172decide whether other types of values are stable enough, and therefore
1173don't feel it's right to document them. For now, don't assume in your
1174code that the values of overlay priority can only be either nil or an
1175integer, always test them with an appropriate predicate to be one or
1176the other. If you need to sort arbitrary overlays into priority
1177order, `overlays-at' can now optionally do this.
1178You should still only specify integer priorities on overlays you create.
1179
1180** The cars of the elements in `interpreter-mode-alist' are now
1181treated as regexps rather than literal strings.
1182
1183** `overriding-terminal-local-map' no longer replaces the local keymaps.
1184It used to disable the minor mode, major mode, and text-property keymaps,
1185whereas now it simply has higher precedence.
1186
1187** `kill-region' has lost its `yank-handler' optional argument.
1188
1189** `(input-pending-p)' no longer runs other timers that are ready to run.
1190The new optional CHECK-TIMERS parameter allows for the prior behavior.
1191
1192** `defvar' and `defcustom' in a let-binding affect the "external" default.
1193
1194** The syntax of ?» and ?« is now punctuation instead of matched parens.
1195Some languages match those as »...«, and others as «...», so it is
1196better for Emacs to stay neutral by default.
1197
1198** `read-event' does not always decode chars in ttys any more. As was the case
1199in Emacs 22 and before, `read-event' (and `read-char') by default read raw
1200bytes from the terminal. If you want to read decoded chars instead (as was
1201always the case in Emacs-23, for example), pass a non-nil
1202`inherit-input-method' argument.
1203
1204** In `symbol-function', nil and "unbound" are indistinguishable.
1205`symbol-function' does not signal a `void-function' error any more.
1206To determine if a symbol's function definition is void, use `fboundp'.
1207
1208** `defadvice' does not honor the `freeze' flag and cannot advise
1209special-forms any more.
1210
1211** `dolist' no longer binds VAR while evaluating the RESULT form,
1212when lexical binding is enabled. Previously, VAR was bound to nil,
1213which often led to spurious unused-variable warnings.
1214
1215** The return value of `backup-buffer' has changed.
1216The second argument is no longer an SELinux context, instead it is an
1217alist of extended attributes as returned by the new function
1218`file-extended-attributes'. The attributes can be applied to another
1219file using `set-file-extended-attributes'.
1220
1221** By default `copy-file' no longer copies file permission bits to an
1222existing destination; and it sets the file permission bits of a newly
1223created destination to those of the source, masked by the default file
1224permissions. To copy the file permission bits, pass t as the
1225PRESERVE-PERMISSIONS argument of `copy-file'.
1226
1227** `visited-file-modtime' now returns -1 for nonexistent files.
1228Formerly it returned a list (-1 LOW USEC PSEC), but this was ambiguous
1229in the presence of files with negative time stamps.
1230
1231** Frame-local variables that affect redisplay do not work any more.
1232More specifically, redisplay does not bother to check for a frame-local
1233value when looking up variables.
1234
1235** In compiled Lisp files, the header no longer includes a timestamp.
1236
1237** The option `inhibit-local-menu-bar-menus' has been removed.
1238
1239
1240* Lisp Changes in Emacs 24.4
1241
1242** Change to the Emacs Lisp coding conventions: the package descriptor
1243and name of global variables, constants, and functions should be separated
1244by two hyphens if the symbol is not meant to be used by other packages.
1245
1246** The second argument of `eval' can now specify a lexical environment.
1247
1248** New macro `define-alternatives' can be used to define generic commands.
1249Generic commands are interactive functions whose implementation can be
1250selected among several alternatives, as a matter of user preference.
1251
1252** Numeric comparison functions =, <, >, <=, >= can now take many arguments.
1253
1254** New functions `special-form-p' and `macrop'.
1255
1256** New macro `with-eval-after-load'.
1257This is like the old `eval-after-load', but better behaved.
1258
1259** If you give a symbol a `defalias-fset-function' property, `defalias'
1260on that symbol will use the associated value as a function to call
1261in place of `fset'.
1262
1263** New variable `enable-dir-local-variables'.
1264Directory-local variables are ignored if this is nil. This may be
1265useful for modes that want to ignore directory-locals while still
1266respecting file-local variables.
1267
1268** `read-regexp' now uses the new variable `read-regexp-defaults-function'
1269as a function to call to provide default values.
1270
1271** New functions `group-gid' and `group-real-gid'.
1272
1273** New function `get-pos-property'.
1274
1275** New hook `pre-redisplay-function'.
1276
1277** `byte-compile-interactive-only-functions' is now obsolete.
1278To specify that a command should only be called interactively, give it
1279a non-nil `interactive-only' property.
1280
1281** New function `string-suffix-p'.
1282
1283** `split-string' now takes an optional argument TRIM.
1284The value, if non-nil, is a regexp that specifies what to trim from
1285the start and end of each substring.
1286
1287** Completion
1288
1289*** The separator used by `completing-read-multiple' is now a regexp.
1290The default `crm-separator' has been changed to allow surrounding spaces
1291around the comma.
1292
1293*** New function `completion-table-with-cache' is a wrapper for
1294`completion-table-dynamic' that caches the result of the last lookup.
1295
1296*** New function `completion-table-merge' to combine several
1297completion tables by merging their completions.
1298
1299*** The `common-substring' argument of `display-completion-list',
1300which has been documented as obsolete since Emacs 23.1, is now _really_
1301obsolete, and no longer advertised. Instead either call
1302`completion-hilit-commonality' to add the highlighting; or use
1303`completion-all-completions', which returns highlighted strings.
1304
1305** Encoding and decoding of text
1306
1307*** New coding-system `prefer-utf-8'.
1308This is like `undecided' but prefers UTF-8 on decoding if the text to
1309be decoded does not contain any invalid UTF-8 sequences. On encoding,
1310any non-ASCII characters are automatically encoded as UTF-8.
1311
1312*** New attributes of coding-systems whose type is `undecided'.
1313Two new attributes, `:inhibit-null-byte-detection' and
1314`:inhibit-iso-escape-detection', determine how to detect encoding of
1315text that includes null bytes and ISO-2022 escape sequences, respectively.
1316Each of these attributes can be either nil, zero, or t. If t, decoding
1317text ignores null bytes and ISO-2022 sequences, respectively. If nil,
1318null bytes cause text to be decoded with no-conversion, and ISO-2022
1319sequences cause Emacs to assume the text is encoded in one of the ISO-2022
1320encodings, such as iso-2022-7bit. If zero, Emacs consults the variables
1321`inhibit-null-byte-detection' and `inhibit-iso-escape-detection'.
1322The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer
1323UTF-8 encoding and decoding, whenever possible.
1324
1325These attributes are only meaningful for coding-systems of type `undecided'.
1326(The type of a coding-system is determined by its `:coding-type' attribute
1327and can be accessed by calling the `coding-system-type' function.)
1328
1329** Error-handling
1330
1331*** New function `define-error'.
1332
1333*** `with-demoted-errors' takes an additional argument `format'.
1334
1335** Faces
1336
1337*** Face specs set via Custom themes now replace the `defface' spec
1338rather than inheriting from it. In other words, setting a face via a
1339theme now behaves like setting it via Customize: you only need to
1340specify the attributes that you want, you don't need to unset those
1341that you don't want.
1342
1343*** The function `face-spec-set' is now like `setq' for face specs.
1344Its third arg now accepts values specifying a face spec type (defface,
1345custom, or override spec), and the relevant spec is set accordingly.
1346
1347*** New face spec attribute :distant-foreground
1348specifies foreground to use if background color is near the foreground
1349color that would otherwise have been used.
1350
1351*** New function `add-face-text-property', which can be used to
1352conveniently prepend/append new face properties.
1353
1354*** New face characteristic (supports :underline (:style wave))
1355specifies whether or not the terminal can display a wavy line.
1356
1357** File-handling
1358
1359*** Support for filesystem notifications.
1360Emacs now supports notifications of filesystem changes, such as
1361creation, modification, and deletion of files. This requires the
1362`glib' API, or the 'inotify' API (on GNU/Linux systems only). On
1363MS-Windows systems, this is supported for Windows XP and newer.
1364
1365*** The 9th element returned by `file-attributes' is now unspecified.
1366Formerly, it was t if the file's gid would change if file were deleted
1367and recreated. This value has been inaccurate for years on many
1368platforms, and nobody seems to have noticed or cared.
1369
1370*** The 6th argument to `copy-file' has been renamed to
1371PRESERVE-PERMISSIONS as it now handles ACL entries and the traditional
1372Unix file permission bits as well as SELinux context.
1373
1374*** The function `file-ownership-preserved-p' now has an optional
1375argument GROUP which causes it check for file group too. This can be
1376used in place of the 9th element of `file-attributes'.
1377
1378*** The function `set-visited-file-modtime' now accepts a 0 or -1 argument,
1379with the same interpretation as the returned value of `visited-file-modtime'.
1380
1381** Image API
1382
1383*** `image-animated-p' is now `image-multi-frame-p'.
1384It returns non-nil for any image that contains multiple frames,
1385whether or not it specifies a frame delay.
1386
1387*** New variable `image-default-frame-delay' gives the frame delay for
1388animated images which do not specify a frame delay.
1389
1390*** New functions `image-current-frame' and `image-show-frame' for getting
1391and setting the current frame of a multi-frame image.
1392
1393** ImageMagick
1394
1395*** ImageMagick images now support the :max-width and :max-height keywords.
1396
1397*** When using `create-image' with image data, you can pass a :format
1398attribute (via the property-list argument) in order to help
1399ImageMagick detect the image type. The value should be a MIME
1400content-type that is found in the new variable `image-format-suffixes'.
1401
1402** Revert and Autorevert
1403
1404*** If Emacs is compiled with file notification support, it uses notifications
1405instead of checking file time stamps. To disable this, set the user option
1406`auto-revert-use-notify' to nil. Alternatively, you can specify a regular
1407expression matching directories to be excluded from file notifications via
1408`auto-revert-notify-exclude-dir-regexp'.
1409
1410*** The default values of `buffer-stale-function', `revert-buffer-function',
1411and `revert-buffer-insert-file-contents-function' are no longer nil.
1412Instead they default to functions that do what the nil value used to.
1413
1414*** `buffer-stale-function' is now used for buffers visiting files too.
1415
1416*** The new user option `auto-revert-remote-files' enables reversion
1417of remote files, if non-nil.
1418
1419** Terminal
1420
1421*** Functions to pop up menus and dialogs now work on all terminals,
1422including TTYs. This includes `x-popup-menu', `x-popup-dialog',
1423`message-box', `yes-or-no-p', etc.
1424
1425The function `display-popup-menus-p' will now return non-nil for a
1426display or frame whenever a mouse is supported on that display or frame.
1427
1428*** New hook `tty-setup-hook', run at the end of initializing a text terminal.
1429
1430*** The hook `term-setup-hook' is obsolete. It is entirely equivalent
1431to `emacs-startup-hook'. See also the new `tty-setup-hook'.
1432
1433** Minor internal changes to the details of lock files.
1434The lock for DIR/FILE is now _always_ DIR/.#FILE.
1435If DIR/.#FILE already exists and is not an Emacs lock file,
1436Emacs makes no attempt to lock DIR/FILE. (Previously, it fell back to
1437numbered lock files DIR/.#FILE.0...).
1438On file systems that do not support symbolic links, the lock is now a
1439regular file with contents being what would have been in the symlink.
1440
1441** New bool-vector set operation functions:
1442*** `bool-vector-exclusive-or'
1443*** `bool-vector-union'
1444*** `bool-vector-intersection'
1445*** `bool-vector-set-difference'
1446*** `bool-vector-not'
1447*** `bool-vector-subsetp'
1448*** `bool-vector-count-consecutive'
1449*** `bool-vector-count-population'
1450
1451** New library subr-x.el with miscellaneous small utility functions:
1452*** `hash-table-keys'
1453*** `hash-table-values'
1454*** `string-blank-p'
1455*** `string-empty-p'
1456*** `string-join'
1457*** `string-reverse'
1458*** `string-trim-left'
1459*** `string-trim-right'
1460*** `string-trim'
1461*** `string-remove-prefix'
1462*** `string-remove-suffix'
1463
1464** The `time-to-seconds' alias to `float-time' is no longer marked obsolete.
1465
1466** The spelling of the rx.el category `chinese-two-byte' has been
1467corrected (the first 'e' was missing).
1468
1469** EIEIO namespace cleanup, obsolete-aliasing functions to use `eieio-' prefix:
1470*** object-name -> eieio-object-name
1471*** object-class -> eieio-object-class
1472*** object-class-fast -> eieio--object-class
1473*** object-class-name -> eieio-object-class-name
1474*** object-name-string -> eieio-object-name-string
1475*** object-num-slots -> eieio--object-num-slots
1476*** object-set-name-string -> eieio-object-set-name-string
1477*** class-of -> eieio-object-class
1478*** class-name -> eieio-class-name
1479*** class-parent -> eieio-class-parent
1480*** class-parents -> eieio-class-parents
1481*** class-parents-fast -> eieio-class-parents-fast
1482*** class-children -> eieio-class-children
1483*** class-num-slots -> eieio--class-num-slots
1484*** class-precedence-list -> eieio-class-precedence-list
1485*** class-direct-subclasses -> eieio-class-children
1486*** class-direct-superclasses -> eieio-class-parents
1487
1488** Obsoleted functions
1489*** `log10'
1490*** `dont-compile'
1491*** `lisp-complete-symbol'
1492*** `field-complete'
1493*** `minibuffer-completion-contents'
1494*** `isearch-nonincremental-exit-minibuffer'
1495*** `isearch-filter-visible'
1496*** `generic-make-keywords-list'
1497*** `get-upcase-table' (use `case-table-get-table' instead).
1498
1499** `with-wrapper-hook' is obsoleted by `add-function'.
1500The few hooks that used with-wrapper-hook are replaced as follows:
1501*** `abbrev-expand-function' obsoletes `abbrev-expand-functions'.
1502*** `completion-in-region-function' obsoletes `completion-in-region-functions'.
1503*** `filter-buffer-substring-function' obsoletes `filter-buffer-substring-functions'.
1504
1505
1506* Changes in Emacs 24.4 on Non-Free Operating Systems
1507
1508** New Core Text based font backend for Mac OS X 10.5 and newer.
1509To use the old font backend, use the following on the command line:
1510 % defaults write org.gnu.Emacs FontBackend ns
1511GNUstep and Mac OS X 10.4 use the old font backend.
1512
1513** Improved fullscreen support on Mac OS X 10.7 and newer, where the
1514default fullscreen method is now "native" fullscreen. To use the
1515old style fullscreen, customize `ns-use-native-fullscreen' to nil.
1516
1517** On Mac OS X 10.7 and newer, Emacs can use sRGB colorspace, and does so
1518by default. Customize `ns-use-srgb-colorspace' to go back to the old method.
1519Note that this does not apply to images.
1520
1521** The procedure for building Emacs on MS-Windows has changed.
1522It is now built by running the same configure script as on all other
1523platforms. This requires the MSYS environment and MinGW development
1524tools. See the updated instructions in nt/INSTALL for details.
1525
1526Using the Posix configure script and Makefiles also means a change in
1527the directory structure of the Emacs installation on Windows. It is
1528now the same as on GNU and Unix systems. In particular, the auxiliary
1529programs, such as cmdproxy.exe and hexl.exe, are in
1530libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs
1531version), version-independent site-lisp is in share/emacs/site-lisp,
1532version-specific Lisp files are in share/emacs/VERSION/lisp and in
1533share/emacs/VERSION/site-lisp, Info docs are in share/info, and data
1534files are in share/emacs/VERSION/etc. (Emacs knows about all these
1535directories and will find the files in there automatically; there's no
1536need to set any variables due to this change.)
1537
1538** Emacs on Windows 2000 and later can now access files and directories
1539whose names cannot be encoded in the current system codepage.
1540
1541The new variable `w32-unicode-filenames' controls this feature: if it
1542is t, Emacs uses Unicode APIs to pass file names to system calls,
1543which lifts the limitation of file names to the current locale.
1544
1545** Lock files now work on MS-Windows.
1546This helps to prevent losing your edits if the same file is being
1547edited in another Emacs session or by another user. See the node
1548"Interlocking" in the Emacs User Manual for the details. To disable
1549file locking, customize `create-lockfiles' to nil.
1550
1551** The "generate a backtrace on fatal error" feature now works on MS-Windows.
1552The backtrace is written to the 'emacs_backtrace.txt' file in the
1553directory where Emacs was running.
1554
1555** The `network-interface-list' and `network-interface-info' functions
1556are now available on MS-Windows.
1557
1558** The variable `buffer-file-type' is no longer supported.
1559Setting it has no effect, and %t in the mode-line format is ignored.
1560Likewise, `file-name-buffer-file-type-alist' is now obsolete, and
1561modifying it has no effect.
1562
1563
1564* Installation Changes in Emacs 24.3
1565
1566** The default X toolkit is now Gtk+ version 3.
1567If you don't pass `--with-x-toolkit' to configure, or if you use
1568`--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try
1569to build with Gtk+ version 3, and if that fails, try Gtk+ version 2.
1570You can explicitly require a specific version by passing
1571`--with-x-toolkit=gtk2' or `--with-x-toolkit=gtk3' to configure.
1572
1573** New configure option `--enable-link-time-optimization', to utilize
1574an appropriate feature provided by GCC since version 4.5.0.
1575
1576** New configure option `--without-all' to disable most of the optional
1577features (image support, etc.) that are normally enabled by default.
1578
1579** New configure option `--enable-gcc-warnings' (for developing/debugging
1580Emacs). If building with GCC, this enables compile-time checks that
1581warn/give errors about possibly-questionable C code. On a recent GNU
1582system there should be no warnings; on older and on non-GNU systems
1583the results may be useful to developers.
1584
1585** The configure option `--enable-use-lisp-union-type' has been
1586renamed to `--enable-check-lisp-object-type', as the resulting
1587Lisp_Object type no longer uses a union to implement the compile time
1588check that this option enables.
1589
1590** The configure option `--disable-maintainer-mode' has been removed,
1591as it was confusingly-named and rarely useful.
1592
1593** The configure options `--program-prefix', `--program-suffix', and
1594`--program-transform-name' apply to more than just the installed
1595binaries. Now they also affect the man pages, icons, and the
1596etc/emacs.desktop file; but not the info pages, since this would break
1597links between the various manuals.
1598
1599** You can use `NO_BIN_LINK=t make install' to prevent the installation
1600overwriting "emacs" in the installation bin/ directory with a link
1601to "emacs-VERSION".
1602
1603** Emacs uses libtinfo in preference to libncurses, if available.
1604
1605** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and
1606/usr/pkg/lib to the linker search path. You must add them yourself if
1607you want them.
1608
1609** The standalone scripts `rcs-checkin' and `vcdiff' have been removed
1610(from the bin and libexec directories, respectively). The former is
1611no longer relevant, the latter is replaced by lisp (in vc-sccs.el).
1612
1613
1614* Startup Changes in Emacs 24.3
1615
1616** Emacs no longer searches for `leim-list.el' files beneath the standard
1617lisp/ directory. There should not be any there anyway. If you have
1618been adding them there, put them somewhere else; e.g., site-lisp.
1619
1620** The `--no-site-lisp' command line option now works for Nextstep builds.
1621
1622
1623* Changes in Emacs 24.3
1624
1625** Help
1626
1627*** `C-h f' (`describe-function') can now perform autoloading.
1628When this command is called for an autoloaded function whose docstring
1629contains a key substitution construct, that function's library is
1630automatically loaded, so that the documentation can be shown
1631correctly. To disable this, set `help-enable-auto-load' to nil.
1632
1633*** `C-h f' now reports previously-autoloaded functions as "autoloaded",
1634even after their associated libraries have been loaded (and the
1635autoloads have been redefined as functions).
1636
1637** ImageMagick
1638
1639*** Images displayed via ImageMagick now support transparency and the
1640:background image specification property.
1641
1642*** When available, ImageMagick support is automatically enabled.
1643It is no longer necessary to call `imagemagick-register-types'
1644explicitly to install ImageMagick image types; that function is called
1645automatically at startup, or when customizing an imagemagick- option.
1646
1647*** Setting `imagemagick-types-inhibit' to t now disables the use of
1648ImageMagick to view images. (You must call `imagemagick-register-types'
1649afterwards if you do not use customize to change this.)
1650
1651*** The new variable `imagemagick-enabled-types' also affects which
1652ImageMagick types are treated as images. The function
1653`imagemagick-filter-types' returns the list of types that will be
1654treated as images.
1655
1656** Minibuffer
1657
1658*** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
1659next and previous path separator, respectively.
1660
1661*** `minibuffer-electric-default-mode' can shorten "(default ...)" to "[...]"
1662in minibuffer prompts. Just set `minibuffer-eldef-shorten-default'
1663non-nil before enabling the mode.
1664
1665** Mode line
1666
1667*** New option `mode-line-default-help-echo' specifies the help text
1668(shown in a tooltip or in the echo area) for any part of the mode line
1669that does not have its own specialized help text.
1670
1671*** You can now click mouse-3 in the coding system indicator to invoke
1672`set-buffer-file-coding-system'.
1673
1674** Server and client
1675
1676*** emacsclient now obeys string values for `initial-buffer-choice',
1677if it is told to open a new frame without specifying any file to visit
1678or expression to evaluate.
1679
1680*** New option `server-auth-key' specifies a shared server key.
1681
1682** Emacs now generates backtraces on fatal errors.
1683On encountering a fatal error, Emacs now outputs a textual description
1684of the fatal signal, and a short backtrace on platforms like glibc
1685that support backtraces.
1686
1687** `C-x C-q' is now bound to the new minor mode `read-only-mode'.
1688This minor mode replaces `toggle-read-only', which is now obsolete.
1689
1690** Most `y-or-n' prompts now allow you to scroll the selected window.
1691Typing `C-v' or `M-v' at a y-or-n prompt scrolls forward or backward
1692respectively, without exiting from the prompt.
1693
1694** In the Package Menu, newly-available packages are listed as "new",
1695and sorted above the other "available" packages by default.
1696
1697** If your Emacs was built from a repository checkout, the new variable
1698`emacs-bzr-version' contains information about the bzr revision used.
1699
1700** New option `create-lockfiles' specifies usage of lockfiles.
1701It defaults to t. Changing it to nil inhibits the creation of lock
1702files (use this with caution).
1703
1704** New option `enable-remote-dir-locals', if non-nil, allows directory-local
1705variables on remote hosts.
1706
1707** The entry for PCL-CVS has been removed from the Tools menu.
1708The PCL-CVS commands are still available via the keyboard.
1709
1710** Using "unibyte: t" in Lisp source files is obsolete.
1711Use "coding: raw-text" instead.
1712
1713** In the buffer made by `M-x report-emacs-bug', the `C-c m' binding
1714has been changed to `C-c M-i' (`report-emacs-bug-insert-to-mailer').
1715The previous binding, introduced in Emacs 24.1, was a mistake, because
1716`C-c LETTER' bindings are reserved for user customizations.
1717
1718** Internationalization
1719
1720*** New language environment: Persian.
1721
1722*** New input method `vietnamese-vni'.
1723
1724** Nextstep (GNUstep / Mac OS X) port
1725
1726*** Support for fullscreen and the frame parameter fullscreen.
1727
1728*** A file dialog is used for open/save operations initiated from the
1729menu/toolbar.
1730
1731
1732* Editing Changes in Emacs 24.3
1733
1734** Search and Replace
1735
1736*** Non-regexp Isearch now performs "lax" space matching.
1737Each sequence of spaces in the supplied search string may match any
1738sequence of one or more whitespace characters, as specified by the
1739variable `search-whitespace-regexp'. (This variable is also used by a
1740similar existing feature for regexp Isearch.)
1741
1742*** New Isearch command `M-s SPC' toggles lax space matching.
1743This applies to both ordinary and regexp Isearch.
1744
1745*** New option `replace-lax-whitespace'.
1746If non-nil, `query-replace' uses flexible whitespace matching too.
1747The default is nil.
1748
1749*** Global `M-s _' starts a symbol (identifier) incremental search,
1750and `M-s _' in Isearch toggles symbol search mode.
1751`M-s c' in Isearch toggles search case-sensitivity.
1752
1753** Navigation commands
1754
1755*** New binding `M-g c' for `goto-char'.
1756
1757*** New binding `M-g TAB' for `move-to-column'.
1758
1759*** `M-g TAB' (`move-to-column') prompts for a column number if called
1760interactively with no prefix arg. Previously, it moved to column 1.
1761
1762** New option `yank-handled-properties' allows processing of text
1763properties on yanked text, in ways that are more general than just
1764removing them (as is done by `yank-excluded-properties').
1765
1766** New option `delete-trailing-lines' specifies whether
1767M-x delete-trailing-whitespace should delete trailing lines at the end
1768of the buffer. It defaults to t.
1769
1770** `C-u M-=' now counts lines/words/characters in the entire buffer.
1771
1772** `C-x 8 RET' is now bound to `insert-char', which is now a command.
1773`ucs-insert' is now an obsolete alias for `insert-char'.
1774
1775** The `z' key no longer has a binding in most special modes.
1776It used to be bound to `kill-this-buffer', but `z' is too easy to
1777accidentally type.
1778
1779** New command `C-x r M-w' (`copy-rectangle-as-kill').
1780It copies the region-rectangle as the last rectangle kill.
1781
1782** Registers
1783
1784*** `C-x r +' is now overloaded to invoke `append-to-register'.
1785
1786*** New option `register-separator' specifies the register containing
1787the text to put between collected texts for use with
1788M-x append-to-register and M-x prepend-to-register.
1789
1790
1791* Changes in Specialized Modes and Packages in Emacs 24.3
1792
1793** Common Lisp emulation (CL)
1794
1795*** CL's main entry is now (require 'cl-lib).
1796`cl-lib' is like the old `cl' except that it uses the namespace cleanly;
1797i.e., all its definitions have the "cl-" prefix (and internal definitions
1798use the "cl--" prefix).
1799
1800If `cl' provided a feature under the name `foo', then `cl-lib'
1801provides it under the name `cl-foo' instead; with the exceptions of the
1802few `cl' definitions that had to use `foo*' to avoid conflicts with
1803pre-existing Elisp entities. These have been renamed to `cl-foo'
1804rather than `cl-foo*'.
1805
1806The old `cl' is now deprecated and is mainly just a bunch of aliases that
1807provide the old, non-prefixed names. Some exceptions are listed below:
1808
1809*** `cl-flet' is not like `flet' (which is deprecated).
1810Instead it obeys the behavior of Common-Lisp's `flet'.
1811In particular, in cl-flet function definitions are lexically scoped,
1812whereas in flet the scoping is dynamic.
1813
1814*** `cl-labels' is slightly different from `labels'.
1815The difference is that it relies on the `lexical-binding' machinery
1816(as opposed to the `lexical-let' machinery used previously) to capture
1817definitions in closures, so such closures will only work if `lexical-binding'
1818is in use.
1819
1820*** `cl-letf' is not exactly like `letf'.
1821The only difference is in details that relate to some deprecated usage
1822of `symbol-function' in place forms.
1823
1824*** `progv' was rewritten to use the `let' machinery.
1825A side effect is that variables without corresponding values are bound
1826to nil rather than being made unbound.
1827
1828*** The following methods of extending `setf' are obsolete
1829(use features from gv.el instead):
1830`define-modify-macro' (use `gv-letplace')
1831`defsetf' (use `gv-define-simple-setter' or `gv-define-setter')
1832`define-setf-expander' (use `gv-define-setter' or `gv-define-expander')
1833`get-setf-method' no longer exists (see "Incompatible Lisp Changes")
1834
1835** Diff mode
1836
1837*** Changes are now highlighted using the same color scheme as in
1838modern VCSes. Deletions are displayed in red (new faces
1839`diff-refine-removed' and `smerge-refined-removed', and new definition
1840of `diff-removed'), insertions in green (new faces `diff-refine-added'
1841and `smerge-refined-added', and new definition of `diff-added').
1842
1843*** The variable `diff-use-changed-face' defines whether to use the
1844face `diff-changed', or `diff-removed' and `diff-added' to highlight
1845changes in context diffs.
1846
1847*** The new command `diff-delete-trailing-whitespace' removes trailing
1848whitespace introduced by a diff.
1849
1850** Ediff now uses the same color scheme as Diff mode.
1851
1852** Python mode
1853
1854A new version of python.el, which provides several new features, including:
1855per-buffer shells, better indentation, Python 3 support, and improved
1856shell-interaction compatible with iPython (and virtually any other
1857text based shell).
1858
1859*** Some user options have been replaced/renamed, including (old -> new):
1860**** python-indent -> python-indent-offset
1861**** python-guess-indent -> python-indent-guess-indent-offset
1862**** python-pdbtrack-do-tracking-p -> python-pdbtrack-activate
1863**** python-use-skeletons -> python-skeleton-autoinsert
1864
1865*** Some user options have been removed, including:
1866
1867**** `python-indent-string-contents': Strings are never indented.
1868
1869**** `python-honour-comment-indentation':
1870Comments are always considered as indentation markers.
1871
1872**** `python-continuation-offset': Indentation is automatically
1873calculated in a pep8 compliant way depending on the context.
1874
1875**** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist':
1876Have no direct mapping as the shell interaction is completely different.
1877
1878**** `python-python-command', `python-jython-command':
1879Replaced by `python-shell-interpreter'.
1880
1881**** `inferior-python-filter-regexp', `python-remove-cwd-from-path',
1882`python-pdbtrack-minor-mode-string', `python-source-modes':
1883No longer relevant.
1884
1885*** Some commands have been replaced (old -> new):
1886**** python-insert-class -> python-skeleton-class
1887**** python-insert-def -> python-skeleton-def
1888**** python-insert-for -> python-skeleton-for
1889**** python-insert-if -> python-skeleton-if
1890**** python-insert-try/except -> python-skeleton-try
1891**** python-insert-try/finally -> python-skeleton-try
1892**** python-insert-while -> python-skeleton-while
1893**** python-find-function -> python-nav-jump-to-defun
1894**** python-next-statement -> python-nav-forward-sentence
1895**** python-previous-statement -> python-nav-backward-sentence
1896**** python-beginning-of-defun-function -> python-nav-beginning-of-defun
1897**** python-end-of-defun-function -> python-nav-end-of-defun
1898**** python-send-buffer -> python-shell-send-buffer
1899**** python-send-defun -> python-shell-send-defun
1900**** python-send-region -> python-shell-send-region
1901**** python-send-region-and-go -> emulate with python-shell-send-region
1902and python-shell-switch-to-shell
1903**** python-send-string -> python-shell-send-string
1904**** python-switch-to-python -> python-shell-switch-to-shell
1905**** python-describe-symbol -> python-eldoc-at-point
1906
1907** D-Bus
1908
1909*** New variables `dbus-compiled-version' and `dbus-runtime-version'.
1910
1911*** The D-Bus object manager interface is implemented.
1912
1913*** Variables of type :(u)int32 and :(u)int64 accept floating points,
1914if their value does not fit into Emacs's integer range.
1915
1916*** The function `dbus-call-method' is now non-blocking.
1917It can be interrupted by `C-g'. `dbus-call-method-non-blocking' is obsolete.
1918
1919*** Signals can also be sent as unicast messages.
1920
1921*** The argument list of `dbus-register-signal' has been extended,
1922according to the new match rule types of D-Bus.
1923
1924*** `dbus-init-bus' supports private connections.
1925
1926*** There is a new function `dbus-setenv'.
1927
1928** `desktop-path' no longer includes the "." directory.
1929Desktop files are now located in ~/.emacs.d by default.
1930
1931** Dired
1932
1933*** `dired-do-async-shell-command' executes each file sequentially
1934if the command ends in `;' (when operating on multiple files).
1935Otherwise, it executes the command on each file in parallel.
1936
1937*** Typing `M-n' in the minibuffer of `dired-do-chmod', `dired-do-chgrp',
1938`dired-do-chown', and `dired-do-touch' yanks the attributes of the
1939file at point.
1940
1941*** When the region is active, `m' (`dired-mark'), `u' (`dired-unmark'),
1942`DEL' (`dired-unmark-backward'), and `d' (`dired-flag-file-deletion')
1943mark/unmark/flag all files in the active region.
1944
1945*** The minibuffer default for `=' (`dired-diff') has changed.
1946It is now the backup file for the file at point, if one exists.
1947In Transient Mark mode the default is the file at the active mark.
1948
1949*** `M-=' is no longer bound to `dired-backup-diff' in Dired buffers.
1950The global binding for `M-=', `count-words-region' is in effect.
1951
1952** ERC
1953
1954*** New module "notifications", which can send a notification when you
1955receive a private message or your nickname is mentioned.
1956
1957*** ERC will look up server/channel names via auth-source and use any
1958channel keys found.
1959
1960*** New option `erc-lurker-hide-list', similar to `erc-hide-list', but
1961only applies to messages sent by lurkers.
1962
1963** reStructuredText mode
1964
1965*** Keybindings (see `C-c C-h'), TAB indentation, filling and auto-filling,
1966fontification, comment handling, and customization have all been revised
1967and improved.
1968
1969*** Support for `imenu' and `which-function-mode'.
1970
1971*** The reStructuredText syntax is more closely covered.
1972Sphinx support has been improved.
1973
1974*** `rst-insert-list' inserts new list or continues existing lists.
1975
1976*** A negative prefix argument always works for `rst-adjust'.
1977
1978*** The window configuration is reset after displaying a TOC.
1979
1980*** The constant `rst-version' describes the rst.el package version.
1981
1982** Ruby mode
1983
1984*** Support for percent literals and recognition of regular expressions
1985in method calls without parentheses with more methods, including Cucumber
1986steps definitions.
1987
1988*** Improved syntax highlighting and indentation.
1989
1990*** New command `ruby-toggle-block', bound to `C-c {'.
1991
1992*** Some non-standard keybindings/commands have been removed:
1993
1994**** `ruby-electric-brace'; use `electric-indent-mode' instead.
1995
1996**** `ruby-mark-defun'; use `mark-defun'.
1997
1998**** `ruby-beginning-of-defun' and `ruby-end-of-defun' are replaced by
1999appropriate settings for the variables `beginning-of-defun-function'
2000and `end-of-defun-function'.
2001
2002**** Non-standard keybindings for `backward-kill-word', `comment-region',
2003`reindent-then-newline-and-indent' and `newline' have been removed.
2004
2005** Shell Script mode
2006
2007*** Pairing of parens/quotes uses `electric-pair-mode' instead of skeleton-pair.
2008
2009*** `sh-electric-here-document-mode' now controls auto-insertion of here-docs.
2010
2011*** `sh-use-smie' lets you choose a new indentation and navigation code.
2012
2013** VHDL mode
2014
2015*** The free software compiler GHDL is supported (and now the default).
2016
2017*** Support for the VHDL-AMS packages has been added/updated.
2018
2019*** Updated to the 2002 revision of the VHDL standard.
2020
2021*** Accepts \r and \f as whitespace.
2022
2023** Apropos
2024
2025*** The faces used by Apropos are now directly customizable.
2026These faces are named `apropos-symbol', `apropos-keybinding', and so on;
2027see the `apropos' Custom group for details.
2028
2029*** The old options whose values specified faces to use have been removed
2030(i.e. `apropos-symbol-face', `apropos-keybinding-face', `apropos-label-face',
2031`apropos-match-face' and `apropos-property-face'.).
2032
2033** Buffer Menu
2034
2035*** This package has been rewritten to use Tabulated List mode.
2036
2037*** Option `Buffer-menu-buffer+size-width' is now obsolete.
2038Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead.
2039
2040** Calc
2041
2042*** Algebraic simplification mode is now the default.
2043To restrict to the limited simplifications given by the former
2044default simplification mode, use `m I'.
2045
2046** Calendar
2047
2048*** You can customize the header text that appears above each calendar month.
2049See the variable `calendar-month-header'.
2050
2051*** New LaTeX calendar style, produced by `cal-tex-cursor-week2-summary'.
2052
2053*** The calendars produced by cal-html include holidays.
2054Customize `cal-html-holidays' to change this.
2055
2056** CEDET
2057
2058*** The major modes from the parser generators "Bovine" and "Wisent"
2059are now properly integrated in Emacs. The file suffixes ".by" and ".wy"
2060are in `auto-mode-alist', and the corresponding manuals are included.
2061
2062*** EDE
2063
2064**** Menu support for the "Configuration" feature. This allows users to
2065choose the active configuration (such as debug or install) from the menu.
2066
2067**** New command `ede-set' to interactively set project-local variables.
2068
2069**** Support for compiling, debugging, and running in "generic" projects.
2070
2071**** Autoconf editing support for M4 macros with complex arguments.
2072
2073**** Compilation support for the "linux" project type.
2074
2075**** "simple" projects have been removed; use "generic" projects instead.
2076
2077*** Semantic
2078
2079**** Support for parsing #include statements inside a namespace in C/C++.
2080
2081**** Improved support for 'extern "C"' declarations in C/C++.
2082
2083**** The ability to ignore more common special C/C++ preprocessor symbols,
2084such as '__nonnull' and '__asm'. Add '__cplusplus' macro when parsing C++.
2085If available, include cdefs.h as an additional source of preprocessor symbols.
2086
2087**** Improved C/C++ function pointer parsing.
2088
2089**** In Python, support for converting imports to include file names.
2090
2091**** Ability to dynamically determine the Python load path.
2092
2093**** Support for the Python 'WITH' and 'AT' keywords.
2094
2095**** Improved tooltip completion.
2096
2097*** SRecode
2098
2099**** The SRecode manual is now included.
2100
2101**** Tag generation supports constructor/destructor settings and system
2102include differentiation.
2103
2104**** Addition of 'Framework' support: Frameworks are specified when a
2105particular kind of library (such as Android) is needed in a common language
2106mode (like Java).
2107
2108**** Support for nested templates and let variables override based on priority.
2109
2110**** Support for merging tables from multiple related modes, such as
2111default -> c++ -> arduino.
2112
2113** Compile has a new option `compilation-always-kill'.
2114
2115** Customize
2116
2117*** `custom-reset-button-menu' now defaults to t.
2118
2119*** Non-option variables are never matched in `customize-apropos' and
2120`customize-apropos-options' (i.e., the prefix argument does nothing for
2121these commands now).
2122
2123** Term
2124
2125*** The variables `term-default-fg-color' and `term-default-bg-color'
2126are now deprecated in favor of the customizable face `term'.
2127
2128*** You can customize how to display ANSI terminal colors and styles
2129by customizing the corresponding `term-color-<COLOR>',
2130`term-color-underline' and `term-color-bold' faces.
2131
2132** Tramp
2133
2134*** The syntax has been extended in order to allow ad-hoc proxy definitions.
2135
2136*** Remote processes are now also supported on remote MS-Windows hosts.
2137
2138** URL
2139
2140*** Structs made by `url-generic-parse-url' have nil `attributes' slot.
2141Previously, this slot stored semicolon-separated attribute-value pairs
2142appended to some imap URLs, but this is not compatible with RFC 3986.
2143So now the `filename' slot stores the entire path and query components,
2144and the `attributes' slot is always nil.
2145
2146*** New function `url-encode-url' for encoding a URI string.
2147The `url-retrieve' function now uses this to encode its URL argument,
2148in case that is not properly encoded.
2149
2150** notifications.el supports now version 1.2 of the Notifications API.
2151The function `notifications-get-capabilities' returns the supported
2152server properties.
2153
2154** Flymake uses fringe bitmaps to indicate errors and warnings.
2155See `flymake-fringe-indicator-position', `flymake-error-bitmap' and
2156`flymake-warning-bitmap'.
2157
2158** The FFAP option `ffap-url-unwrap-remote' can now be a list of strings,
2159specifying URL types that should be converted to remote file names at
2160the FFAP prompt. The default is now '("ftp").
2161
2162** New Ibuffer `derived-mode' filter, bound to `/ M'.
2163The old binding for `/ M' (filter by used-mode) is now bound to `/ m'.
2164
2165** New option `mouse-avoidance-banish-position' specifies where the
2166`banish' mouse avoidance setting moves the mouse.
2167
2168** In Perl mode, new option `perl-indent-parens-as-block' causes non-block
2169closing brackets to be aligned with the line of the opening bracket.
2170
2171** In Proced mode, new command `proced-renice' renices marked processes.
2172
2173** New option `async-shell-command-buffer' specifies the buffer to use
2174for a new asynchronous `shell-command' when the default output buffer
2175`*Async Shell Command*' is already in use.
2176
2177** SQL mode has a new option `sql-db2-escape-newlines'.
2178If non-nil, newlines sent to the command interpreter will be escaped
2179by a backslash. The default does not escape the newlines and assumes
2180that the sql statement will be terminated by a semicolon.
2181
2182** New command `tabulated-list-sort', bound to `S' in Tabulated List mode
2183(and modes that derive from it), sorts the column at point, or the Nth
2184column if a numeric prefix argument is given.
2185
2186** `which-func-modes' now defaults to t, so Which Function mode, when
2187enabled, applies to all applicable major modes.
2188
2189** `winner-mode-hook' now runs when the mode is disabled, as well as when
2190it is enabled.
2191
2192** Follow mode no longer works by using advice.
2193The option `follow-intercept-processes' has been removed.
2194
2195** `javascript-generic-mode' is now an obsolete alias for `js-mode'.
2196
2197** Hooks renamed to avoid obsolete "-hooks" suffix:
2198*** semantic-lex-reset-hooks -> semantic-lex-reset-functions
2199*** semantic-change-hooks -> semantic-change-functions
2200*** semantic-edits-new-change-hooks -> semantic-edits-new-change-functions
2201*** semantic-edits-delete-change-hooks -> semantic-edits-delete-change-functions
2202*** semantic-edits-reparse-change-hooks -> semantic-edits-reparse-change-functions
2203*** semanticdb-save-database-hooks -> semanticdb-save-database-functions
2204*** c-prepare-bug-report-hooks -> c-prepare-bug-report-hook
2205*** rcirc-sentinel-hooks -> rcirc-sentinel-functions
2206*** rcirc-receive-message-hooks -> rcirc-receive-message-functions
2207*** rcirc-activity-hooks -> rcirc-activity-functions
2208*** rcirc-print-hooks -> rcirc-print-functions
2209*** dbus-event-error-hooks -> dbus-event-error-functions

2220
2221** Obsolete packages
2222
2223*** assoc.el
2224In most cases, assoc+member+push+delq work just as well.
2225And in any case it's just a terrible package: ugly semantics, terrible
2226inefficiency, and not namespace-clean.
2227*** bruce.el
2228*** cust-print.el
2229*** ledit.el
2230*** mailpost.el
2231*** mouse-sel.el
2232*** patcomp.el
2233
2234
2235* Incompatible Lisp Changes in Emacs 24.3
2236
2237** Docstrings starting with `*' no longer indicate user options.
2238Only variables defined using `defcustom' are considered user options.
2239The function `user-variable-p' is now an obsolete alias for
2240`custom-variable-p'.
2241
2242** The return values of `defalias', `defun' and `defmacro' have changed,
2243and are now undefined. For backwards compatibility, `defun' and
2244`defmacro' currently return the name of the newly defined
2245function/macro, but this should not be relied upon.
2246
2247** `random' by default now returns a different random sequence in
2248every Emacs run. Use `(random S)', where S is a string, to set the
2249random seed to a value based on S, in order to get a repeatable
2250sequence in later calls.
2251
2252** If the NEWTEXT arg to `replace-match' contains a substring "\?",
2253that substring is inserted literally even if the LITERAL arg is
2254non-nil, instead of causing an error to be signaled.
2255
2256** `select-window' now always makes the window's buffer current.
2257It does so even if the window was selected before.
2258
2259** The function `x-select-font' can return a font spec, instead of a
2260font name as a string. Whether it returns a font spec or a font name
2261depends on the graphical library.
2262
2263** `face-spec-set' no longer sets frame-specific attributes when the
2264third argument is a frame (that usage was obsolete since Emacs 22.2).
2265
2266** `set-buffer-multibyte' now signals an error in narrowed buffers.
2267
2268** The CL package's `get-setf-method' function no longer exists.
2269Generalized variables are now part of core Emacs Lisp, and implemented
2270differently to the way cl.el used to do it. It is not possible to
2271define a compatible replacement for `get-setf-method'. See the file
2272gv.el for internal details of the new implementation.
2273
2274** The arguments of `dbus-register-signal' are no longer just strings,
2275but keywords or keyword-string pairs. The old argument list will
2276still be supported for Emacs 24.x.
2277
2278** Miscellaneous name changes
2279Some Lisp symbols have been renamed to correct their spelling,
2280or to be more consistent with standard Emacs terminology.
2281
2282*** Renamed functions
2283**** hangul-input-method-inactivate -> hangul-input-method-deactivate
2284**** inactivate-input-method -> deactivate-input-method
2285**** quail-inactivate -> quail-deactivate
2286**** robin-inactivate -> robin-deactivate
2287**** viper-inactivate-input-method -> viper-deactivate-input-method
2288**** viper-inactivate-input-method-action ->
2289 viper-deactivate-input-method-action
2290**** ucs-input-inactivate -> ucs-input-deactivate
2291
2292*** Renamed hooks
2293The old hooks are still supported for backward compatibility, but they
2294are deprecated and will be removed eventually.
2295**** input-method-inactivate-hook -> input-method-deactivate-hook
2296**** robin-inactivate-hook -> robin-deactivate-hook
2297**** quail-inactivate-hook -> quail-deactivate-hook
2298
2299*** Renamed variables
2300**** follow-deactive-menu -> follow-inactive-menu
2301**** inactivate-current-input-method-function ->
2302 deactivate-current-input-method-function
2303
2304** Some obsolete functions, variables, and faces have been removed:
2305*** `last-input-char', `last-command-char', `unread-command-char'
2306*** `facemenu-unlisted-faces'
2307*** `rmail-decode-mime-charset'
2308*** `iswitchb-read-buffer'
2309*** `sc-version', `sc-submit-bug-report'
2310*** `set-char-table-default'
2311*** `string-to-sequence' (use `string-to-list' or `string-to-vector')
2312*** `compile-internal'
2313*** `modeline'
2314*** `mode-line-inverse-video'
2315*** `follow-mode-off-hook'
2316*** `cvs-commit-buffer-require-final-newline'
2317(use `log-edit-require-final-newline' instead)
2318*** `cvs-changelog-full-paragraphs'
2319(use `log-edit-changelog-full-paragraphs' instead)
2320*** `cvs-diff-ignore-marks', `cvs-diff-buffer-name'
2321*** `vc-ignore-vc-files' (use `vc-handled-backends' instead)
2322*** `vc-master-templates' (use `vc-handled-backends' instead)
2323*** `vc-checkout-carefully'
2324
2325
2326* Lisp Changes in Emacs 24.3
2327
2328** CL-style generalized variables are now in core Elisp.
2329`setf' is autoloaded; `push' and `pop' accept generalized variables.
2330You can define your own generalized variables using `gv-define-simple-setter',
2331`gv-define-setter', etc.
2332
2333** Emacs tries to macroexpand interpreted (non-compiled) files during load.
2334This can significantly speed up execution of non-byte-compiled code,
2335but can also bump into previously unnoticed cyclic dependencies.
2336These are generally harmless: they will simply cause the macro calls
2337to be left for later expansion (as before), but will result in a
2338warning ("Eager macro-expansion skipped due to cycle") describing the cycle.
2339You may wish to restructure your code so this does not happen.
2340
2341** New sampling-based Elisp profiler.
2342Try M-x profiler-start, do some work, and then call M-x profiler-report.
2343When finished, use M-x profiler-stop. The sampling rate can be based on
2344CPU time or memory allocations.
2345
2346** `defun' also accepts a (declare DECLS) form, like `defmacro'.
2347The interpretation of the DECLS is determined by `defun-declarations-alist'.
2348
2349** New macros `setq-local' and `defvar-local'.
2350
2351** Face underlining can now use a wave.
2352
2353** `read-regexp' has a new argument HISTORY; the first argument PROMPT
2354of `read-regexp' accepts a string ending with a colon and space, and its
2355second argument DEFAULTS can be a list of strings accessible via `M-n'
2356in the minibuffer ahead of other hard-coded useful regexp-related values.
2357More commands use `read-regexp' now to read their regexp arguments.
2358
2359** Completion
2360
2361*** New function `completion-table-with-quoting' to handle completion
2362in the presence of quoting, such as file completion in shell buffers.
2363
2364*** New function `completion-table-subvert' to use an existing completion
2365table, but with a different prefix.
2366
2367** Debugger
2368
2369*** New error type and new function `user-error'.
2370These do not trigger the debugger.
2371
2372*** New option `debugger-bury-or-kill', saying what to do with the
2373debugger buffer when exiting debug.
2374
2375*** Set `debug-on-message' to enter the debugger when a certain
2376message is displayed in the echo area. This can be useful when trying
2377to work out which code is doing something.
2378
2379*** New var `inhibit-debugger', automatically set to prevent accidental
2380recursive invocations.
2381
2382** Window handling
2383
2384*** New command `fit-frame-to-buffer' adjusts the frame height to
2385fit the contents.
2386
2387*** The command `fit-window-to-buffer' can adjust the frame height
2388if the new option `fit-frame-to-buffer' is non-nil.
2389
2390*** New macro `with-temp-buffer-window', similar to
2391`with-output-to-temp-buffer'.
2392
2393*** `temp-buffer-resize-mode' no longer resizes windows that have been
2394reused.
2395
2396*** New option `switch-to-buffer-preserve-window-point' to restore a
2397window's point when switching buffers.
2398
2399*** New display action alist entries `window-height' and `window-width'
2400specify the size of new windows created by `display-buffer'.
2401
2402*** New display action alist entry `pop-up-frame-parameters', if
2403non-nil, specifies frame parameters to give any newly-created frame.
2404
2405*** New display action alist entry `inhibit-switch-frame', if non-nil,
2406tells display action functions to avoid changing which frame is
2407selected.
2408
2409*** New display action alist entry `previous-window', if non-nil,
2410specifies window to reuse in `display-buffer-in-previous-window'.
2411
2412*** New display action functions `display-buffer-below-selected',
2413and `display-buffer-in-previous-window'.
2414
2415*** The functions `get-lru-window', `get-mru-window' and `get-largest-window'
2416now accept a third argument to avoid choosing the selected window.
2417
2418*** Additional values recognized for option `window-combination-limit'.
2419
2420*** The following variables are obsolete, as they can be replaced by
2421appropriate entries in the `display-buffer-alist' function introduced
2422in Emacs 24.1:
2423**** `dired-shrink-to-fit'
2424**** `display-buffer-reuse-frames'
2425**** `display-buffer-function'
2426**** `special-display-buffer-names'
2427**** `special-display-frame-alist'
2428**** `special-display-function'
2429**** `special-display-regexps'
2430
2431** Time
2432
2433*** `current-time-string' no longer requires that its argument's year
2434must be in the range 1000..9999. It now works with any year supported
2435by the underlying C implementation.
2436
2437*** `current-time' now returns extended-format time stamps
2438(HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds.
2439PSEC is typically a multiple of 1000 on current machines. Other
2440functions that use this format, such as `file-attributes' and
2441`format-time-string', have been changed accordingly. Old-format time
2442stamps are still accepted.
2443
2444*** The format of timers in `timer-list' and `timer-idle-list' is now
2445[TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS].
2446The PSECS slot is new, and uses picosecond resolution. It can be
2447accessed via the new `timer--psecs' accessor.
2448
2449*** Last-modified time stamps in undo lists now are of the form
2450(t HI-SECS LO-SECS USECS PSECS) instead of (t HI-SECS . LO-SECS).
2451
2452** EIEIO
2453
2454*** Improved security when handling persistent objects:
2455
2456**** `eieio-persistent-read' now features optional arguments for specifying
2457the class to load, as well as a flag stating whether subclasses are allowed;
2458if provided, other classes will be rejected by the reader. For
2459compatibility with existing code, if the class is omitted only a
2460warning is issued.
2461
2462**** New specialized reader for pulling in classes and signaling errors
2463without evaluation of suspicious code.
2464
2465**** All slots that contain objects must have a :type. Slots with lists
2466of objects must use a new type predicate for a list of an object type.
2467
2468*** Support for `find-function' and similar utilities, through the addition
2469of filename support to generated symbols.
2470
2471** Floating point functions now always return special values like NaN,
2472instead of signaling errors, if given invalid args; e.g., (log -1.0).
2473Previously, they returned NaNs on some platforms but signaled errors
2474on others. The affected functions are acos, asin, tan, exp, expt,
2475log, log10, sqrt, and mod.
2476
2477** New fringe bitmap `exclamation-mark'.
2478
2479** Miscellaneous changes to special forms and macros
2480
2481*** `defun' and `defmacro' are now macros rather than special forms.
2482
2483*** `kbd' is now a function rather than a macro.
2484
2485** Miscellaneous new functions
2486
2487*** `set-temporary-overlay-map' sets up a temporary keymap that
2488takes precedence over most other maps for a short while (normally one key).
2489
2490*** `autoloadp' tests if its argument is an autoloaded object.
2491
2492*** `autoload-do-load' performs the autoloading operation.
2493
2494*** `buffer-narrowed-p' tests if the buffer is narrowed.
2495
2496*** `file-name-base' returns a file name sans directory and extension.
2497
2498*** `function-get' fetches a function property, following aliases.
2499
2500*** `posnp' tests if an object is a `posn'.
2501
2502*** `system-users' returns the user names on the system.
2503
2504*** `system-groups' returns the group names on the system.
2505
2506*** `tty-top-frame' returns the topmost frame of a text terminal.
2507
2508** The following functions and variables are obsolete:
2509*** `automount-dir-prefix' (use `directory-abbrev-alist')
2510*** `buffer-has-markers-at'
2511*** `macro-declaration-function' (use `macro-declarations-alist')
2512*** `window-system-version' (provides no useful information)
2513*** `dired-pop-to-buffer' (use `dired-mark-pop-up')
2514*** `query-replace-interactive'
2515*** `font-list-limit' (has had no effect since Emacs < 23)
2516
2517
2518* Changes in Emacs 24.3 on Non-Free Operating Systems
2519
2520** Cygwin builds can use the native MS Windows user interface.
2521Pass `--with-w32' to configure. The default remains the X11 interface.
2522
2523** Two new functions are available in Cygwin builds:
2524`cygwin-convert-file-name-from-windows' and
2525`cygwin-convert-file-name-to-windows'. These functions allow Lisp
2526code to access the Cygwin file-name mapping machinery to convert
2527between Cygwin and Windows-native file and directory names.
2528
2529** When invoked with the -nw switch to run on the Windows text-mode terminal,
2530Emacs now supports `mouse-highlight', help-echo (in the echo area), and
2531`mouse-autoselect-window'.
2532
2533** On MS Windows Vista and later Emacs now supports symbolic links.
2534
2535** On MS Windows, you can pass `--without-libxml2' to configure.bat to omit
2536support for libxml2, even if its presence is detected.
2537
2538** On Mac OS X, the Nextstep port requires OS X 10.4 or later.
2539
2540** On Mac OS X, configure no longer automatically adds the Fink "/sw"
2541directories to the search path. You must add them yourself if you want them.
2542
2543
2544* Changes in Emacs 24.2
2545
2546** This is mainly a bug-fix release.
2547
2548
2549* Installation Changes in Emacs 24.1
2550
2551** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
2552to configure. Note that other libraries used by Emacs, RSVG and GConf,
2553also depend on Gtk+. You can disable them with --without-rsvg and
2554--without-gconf.
2555
2556** Emacs can be compiled with GnuTLS support.
2557This happens by default if a suitably recent version of the library is
2558found at build time. To prevent this, use the configure option
2559`--without-gnutls'. See below for GnuTLS features.
2560
2561** Emacs can be compiled with SELinux support.
2562This happens by default if a suitably recent version of the library is
2563found at build time. To prevent this, use the configure option
2564`--without-selinux'. See below for SELinux features.
2565
2566** Emacs can be compiled with ImageMagick support.
2567This happens by default if a suitably recent version of the library is
2568found at build time. To prevent this, use the configure option
2569`--without-imagemagick'. See below for ImageMagick features.
2570This feature is not available for the Nextstep or MS ports.
2571
2572** Emacs can be compiled with libxml2 support.
2573This happens by default if a suitably recent version of the library is
2574found at build time. To prevent this, use the configure option
2575`--without-xml2'. See below for libxml2 features.
2576
2577** By default, the installed Info and man pages are compressed.
2578You can disable this by configuring --without-compress-info.
2579
2580** New configure option --with-wide-int.
2581With it, Emacs integers typically have 62 bits, even on 32-bit machines.
2582On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB
2583to about 2 GiB.
2584
2585** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost.
2586These provide no new functionality, they just remove the need to edit
2587lib-src/Makefile by hand in order to use the associated features.
2588
2589** New configure option --enable-use-lisp-union-type.
2590This is only useful for Emacs developers to debug certain types of bugs.
2591This is not a new feature; only the configure flag is new.
2592
2593** The standalone programs digest-doc and sorted-doc are removed.
2594Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'.
2595
2596** The standalone program `fakemail' is removed.
2597If you need it, feedmail.el provides a superset of the functionality.
2598
2599
2600* Startup Changes in Emacs 24.1
2601
2602** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
2603command line arguments, and the EMACS_UNIBYTE environment variable, no
2604longer have any effect. (They were declared obsolete in Emacs 23.)
2605
2606** New command line option `--no-site-lisp' removes site-lisp directories
2607from load-path. -Q now implies this. This option does not affect the
2608EMACSLOADPATH environment variable (and hence has no effect for
2609Nextstep builds).
2610
2611
2612* Changes in Emacs 24.1
2613
2614** Completion
2615
2616*** Many packages now use the `completion-at-point' command,
2617rather than implementing separate completion commands.
2618
2619*** `completion-at-point' now handles tags and semantic completion.
2620
2621*** Completion in a non-minibuffer now tries to detect the end of completion
2622and pops down the *Completions* buffer accordingly.
2623
2624*** New option `completion-cycle-threshold' allows completion cycling.
2625
2626*** New option `completion-category-overrides' for overriding the
2627default completion style in certain circumstances.
2628
2629*** New completion style `substring'.
2630
2631*** Completion of buffer names uses `substring' completion by default.
2632
2633*** The option `widget-complete-field' has been removed.
2634
2635** Mail changes
2636
2637*** The first time you try sending mail, Emacs asks for a mail method.
2638This is implemented by a new default for `send-mail-function', which
2639is `sendmail-query-once'. This offers to use the smtpmail package, or
2640to use the old defaults relying on external mail facilities
2641(`sendmail-send-it' on GNU/Linux and other Unix-like systems, and
2642`mailclient-send-it' on Windows).
2643
2644*** Typing `C-c m' in the buffer made by `M-x report-emacs-bug'
2645transfers the report to your desktop's preferred mail client, if there
2646is one. This uses either the "xdg-email" utility, or Mac OS's "open"
2647command.
2648
2649*** See Changes in Specialized Modes and Packages for SMTPmail changes
2650and Mail mode changes
2651
2652** Emacs server and client changes
2653
2654*** New option `server-port' specifies the port for TCP Emacs servers.
2655
2656*** New emacsclient argument -q/--quiet suppresses some status messages.
2657
2658*** New emacsclient argument --frame-parameters specifies the frame
2659parameters of any newly-created graphical frame.
2660
2661*** If emacsclient shuts down due to Emacs signaling an error,
2662its exit status is 1.
2663
2664*** New emacsclient argument --parent-id ID.
2665This opens a client frame in parent X window ID, via XEmbed, similar
2666to the --parent-id argument to Emacs.
2667
2668** Internationalization changes
2669
2670*** Emacs now supports display and editing of bidirectional text.
2671Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are
2672displayed in the correct visual order as expected by users of those
2673scripts. The display reordering is a "full bidirectionality" class
2674implementation of the Unicode Bidirectional Algorithm (UBA). Buffers
2675with no RTL text should look exactly the same as before.
2676
2677**** New buffer-local variable `bidi-display-reordering'.
2678To disable display reordering in a buffer, change this to nil.
2679
2680**** New buffer-local variable `bidi-paragraph-direction'.
2681If nil (the default), Emacs determines the base direction of each
2682paragraph from its text, as specified by the UBA. Setting the value
2683to `right-to-left' or `left-to-right' forces a base direction on each
2684paragraph.
2685
2686Paragraphs with right-to-left base direction are displayed starting at
2687the right window edge.
2688
2689*** Enhanced support for characters with no glyphs in available fonts,
2690or, on text terminals, characters that cannot be encoded by the
2691terminal coding system. The new option `glyphless-char-display-control'
2692specifies how to display them: as a hexadecimal code in a box, a thin
26931-pixel space, an empty box, etc.
2694
2695*** New input methods for Farsi and Bulgarian
2696(farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic).
2697
2698*** `nobreak-char-display' now also highlights Unicode hyphen chars
2699(U+2010 and U+2011).
2700
2701*** New Hebrew translation of the Emacs Tutorial.
2702Type `C-u C-h t' to choose it in case your language setup doesn't
2703automatically select it.
2704
2705** An Emacs Lisp package manager is now included.
2706This is a convenient way to download and install additional packages,
2707from a package repository at http://elpa.gnu.org.
2708
2709*** M-x list-packages shows a list of packages, which can be
2710selected for installation.
2711
2712*** New command `describe-package', bound to `C-h P'.
2713
2714*** By default, all installed packages are loaded automatically when
2715Emacs starts up. To disable this, set `package-enable-at-startup' to
2716nil. To specify the packages to load, customize `package-load-list'.
2717
2718** Custom theme changes
2719
2720*** New command `M-x customize-themes', which provides a convenient
2721interface for enabling and disabling Custom themes.
2722
2723*** New option `custom-theme-load-path' is the load path for themes.
2724Emacs no longer looks for Custom themes in `load-path'. The default
2725value of `custom-theme-load-path' says to look for themes in
2726`custom-theme-directory', followed by a subdirectory of
2727`data-directory' named "themes/", which contains a small selection of
2728built-in Custom themes.
2729
2730*** New option `custom-safe-themes' records known-safe theme files.
2731If a theme is not in this list, Emacs queries before loading it, and
2732offers to save the theme to `custom-safe-themes' automatically. By
2733default, all themes included in Emacs are treated as safe.
2734
2735** Improved GTK integration
2736
2737*** GTK scroll-bars are now placed on the right by default.
2738The function `set-scroll-bar-mode' can change this.
2739
2740*** GTK tool bars can have just text, just images or images and text.
2741Customize `tool-bar-style' to choose the style. On a Gnome desktop,
2742the default is taken from desktop settings.
2743
2744*** GTK tool bars can be placed on any edge of the frame.
2745The frame-parameter tool-bar-position controls this. It takes the
2746values top, left, right or bottom. The Options => Show/Hide menu has
2747entries for this.
2748
2749*** The default colors for selected text (the `region' face) are taken
2750from the GTK theme when Emacs is built with GTK.
2751
2752*** Emacs uses GTK tooltips by default if built with GTK.
2753You can disable this by changing `x-gtk-use-system-tooltips' to nil.
2754
2755** Graphical interface changes
2756
2757*** On graphical displays, the mode-line no longer ends in dashes.
2758Also, the first dash (which does not indicate anything) is just
2759displayed as a space.
2760
2761*** `menu-bar-select-buffer-function' lets you choose another operation
2762instead of `switch-to-buffer' when selecting an item in the Buffers menu.
2763
2764*** Lucid menus and dialogs can display antialiased fonts if Emacs is
2765built with Xft. These fonts can be set via X resources, for example:
2766Emacs.pane.menubar.font: Courier-12
2767
2768** Exiting changes
2769
2770*** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP,
2771or if it receives a SIGINT signal in batch mode.
2772
2773*** `kill-emacs-hook' is now also run in batch mode.
2774Third-party code which adds to `kill-emacs-hook' should check if they
2775do the right thing in batch mode.
2776
2777** Scrolling changes
2778
2779*** New scrolling commands `scroll-up-command' and `scroll-down-command'
2780(bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom
2781of buffer at first key-press (instead they move to top/bottom of buffer)
2782when `scroll-error-top-bottom' is non-nil.
2783
2784*** New option `scroll-error-top-bottom' (see above).
2785
2786*** New scrolling commands `scroll-up-line' and `scroll-down-line'
2787scroll a line instead of full screen.
2788
2789*** New property `scroll-command' should be set on a command's symbol to
2790define it as a scroll command affected by `scroll-preserve-screen-position'.
2791
2792*** If you customize `scroll-conservatively' to a value greater than 100,
2793Emacs will never recenter point in the window when it scrolls due to
2794cursor motion commands or commands that move point (e.f., `M-g M-g').
2795Previously, you needed to use `most-positive-fixnum' as the value of
2796`scroll-conservatively' to achieve the same effect.
2797
2798*** "Aggressive" scrolling now honors the scroll margins.
2799If you customize `scroll-up-aggressively' or
2800`scroll-down-aggressively' and move point off the window, Emacs now
2801scrolls the window so as to avoid positioning point inside the scroll
2802margin.
2803
2804** Basic SELinux support has been added.
2805This requires Emacs to be linked with libselinux at build time.
2806
2807*** Emacs preserves the SELinux file context when backing up.
2808Also, the function `copy-file' has an extra optional argument for
2809preserving SELinux context, and the return value of `backup-buffer'
2810now includes the SELinux context.
2811
2812*** New functions `file-selinux-context' and `set-file-selinux-context'
2813get and set the SELinux context of a file.
2814
2815** Trash changes
2816
2817*** `delete-by-moving-to-trash' now only affects commands that specify
2818trashing. This avoids inadvertently trashing temporary files.
2819
2820*** Calling `delete-file' or `delete-directory' with a prefix argument
2821now forces true deletion, regardless of `delete-by-moving-to-trash'.
2822
2823** File- and directory-local variable changes
2824
2825*** You can stop directory local vars from applying to subdirectories.
2826Add an element (subdirs . nil) to the alist portion of any variables
2827settings to indicate that the section should not apply to
2828subdirectories.
2829
2830*** Directory local variables can apply to some file-less buffers.
2831Affected modes include dired, vc-dir, and log-edit. For example,
2832adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will
2833turn on `whitespace-mode' for *vc-diff* buffers. Modes should call
2834`hack-dir-local-variables-non-file-buffer' to support this.
2835
2836*** Using "mode: MINOR-MODE" to enable a minor mode is deprecated.
2837Instead, use "eval: (minor-mode 1)".
2838
2839*** The variable `inhibit-first-line-modes-regexps' has been renamed
2840to `inhibit-local-variables-regexps'. As the name suggests, it now
2841applies to ALL file local variables, not just -*- lines. The
2842associated `inhibit-first-line-modes-suffixes' has been renamed in the
2843corresponding way.
2844
2845** Window changes
2846
2847*** The `quit-window' command now restores the last buffer displayed
2848in the quitted window.
2849
2850*** Resizing an Emacs frame now preserves proportional window sizes,
2851modulo restrictions like window minimum sizes and fixed-size windows.
2852
2853*** The behavior of `display-buffer' is now customizable in detail.
2854
2855**** New option `display-buffer-base-action' specifies a list of
2856user-determined display "actions" (functions and optional arguments
2857for choosing the displaying window).
2858
2859This takes precedence over the default display action, which is
2860specified by `display-buffer-fallback-action'.
2861
2862**** New option `display-buffer-alist' maps buffer name regexps to
2863display actions, taking precedence over `display-buffer-base-action'.
2864
2865*** New option `window-combination-limit'.
2866The new option `window-combination-limit' allows to return the space
2867obtained for resizing or creating a window more reliably to the window
2868from which such space was obtained.
2869
2870*** New option `window-combination-resize'.
2871The new option `window-combination-resize' allows to split a window that
2872otherwise cannot be split because it's too small by stealing space from
2873other windows in the same combination. Subsequent resizing or deletion
2874of the window will resize all windows in the same combination as well.
2875
2876*** New option `frame-auto-hide-function' lets you choose between
2877iconifying or deleting a frame when burying a buffer in a dedicated
2878frame, or quitting a window showing a buffer in a frame of its own.
2879
2880*** New commands `maximize-window' and `minimize-window'.
2881These maximize and minimize the size of a window within its frame.
2882
2883*** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'.
2884These functions allow to navigate through the live buffers that have
2885been shown in a specific window.
2886
2887** Minibuffer changes
2888
2889*** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'.
2890This is handy for minibuffer-only frames, and is also used for the feature
2891where mouse-1 pops up *Messages*"', which can now easily be changed.
2892
2893*** Minibuffers set `truncate-lines' to nil.
2894If you want to change the value to something else, you could use
2895for example `minibuffer-setup-hook'.
2896
2897** `auto-mode-case-fold' is now enabled by default.
2898
2899** `backup-by-copying-when-mismatch' now defaults to t.
2900
2901** New basic faces `error', `warning', `success'.
2902These are used to highlight text indicating failure, caution or
2903successful operation.
2904
2905** New option `list-colors-sort' defines the color sort order
2906for `list-colors-display'.
2907
2908** The variable `focus-follows-mouse' now always defaults to nil.
2909
2910
2911* Editing Changes in Emacs 24.1
2912
2913** Search changes
2914
2915*** C-y in Isearch is now bound to `isearch-yank-kill', instead of
2916`isearch-yank-line'.
2917
2918*** M-y in Isearch is now bound to `isearch-yank-pop', instead of
2919`isearch-yank-kill'.
2920
2921*** M-s C-e in Isearch is now bound to `isearch-yank-line'.
2922
2923** New commands `count-words-region' and `count-words'.
2924
2925*** M-= is bound to `count-words-region', not `count-lines-region'.
2926The `count-words-region' command, when called interactively, reports
2927the number of lines, words, and characters in the region. It is a
2928superset of the old `count-lines-region', which is now an obsolete
2929alias for it.
2930
2931** The command `just-one-space' (M-SPC), if given a negative argument,
2932also deletes newlines around point.
2933
2934** Deletion changes
2935
2936*** New option `delete-active-region'.
2937If non-nil, [delete] and DEL delete the region if it is active and no
2938prefix argument is given. If set to `kill', those commands kill
2939instead.
2940
2941*** New command `delete-forward-char', bound to [delete].
2942This is meant for interactive use, and obeys `delete-active-region'.
2943The command `delete-char' does not obey `delete-active-region'.
2944
2945*** `delete-backward-char' is now a Lisp function.
2946Apart from obeying `delete-active-region', its behavior is unchanged.
2947However, the byte compiler now warns if it is called from Lisp; Lisp
2948callers should use delete-char with a negative argument instead.
2949
2950*** The option `mouse-region-delete-keys' has been deleted.
2951
2952** Selection changes.
2953
2954The default handling of clipboard and primary selections has been
2955changed to conform with modern X applications. In short, most
2956commands for killing and yanking text now use the clipboard, while
2957mouse commands use the primary selection.
2958
2959In the following, we provide a list of these changes, followed by a
2960list of steps to get the old behavior back if you prefer that.
2961
2962*** `select-active-regions' now defaults to t.
2963Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
2964the kill ring. The selected text is put in the primary selection, if
2965the system possesses a separate primary selection facility (e.g. X).
2966
2967**** `select-active-regions' also accepts a new value, `only'.
2968This means to only set the primary selection for temporarily active
2969regions (usually made by mouse-dragging or shift-selection);
2970"ordinary" active regions, such as those made with C-SPC followed by
2971point motion, do not alter the primary selection.
2972
2973**** `mouse-drag-copy-region' now defaults to nil.
2974
2975*** mouse-2 is now bound to `mouse-yank-primary'.
2976This pastes from the primary selection, ignoring the kill-ring.
2977Previously, mouse-2 was bound to `mouse-yank-at-click'.
2978
2979*** `x-select-enable-clipboard' now defaults to t on all platforms.
2980
2981*** `x-select-enable-primary' now defaults to nil.
2982Thus, commands that kill text or copy it to the kill-ring (such as
2983M-w, C-w, and C-k) also use the clipboard---not the primary selection.
2984
2985**** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
2986exactly equivalent to M-w, C-w, and C-y respectively.
2987
2988**** Note that on MS-Windows, `x-select-enable-clipboard' was already
2989non-nil by default, as Windows does not support the primary selection
2990between applications.
2991
2992*** To return to the previous behavior, do the following:
2993
2994**** Change `select-active-regions' to nil.
2995**** Change `mouse-drag-copy-region' to t.
2996**** Change `x-select-enable-primary' to t (on X only).
2997**** Change `x-select-enable-clipboard' to nil.
2998**** Bind `mouse-yank-at-click' to mouse-2.
2999
3000*** Support for X cut buffers has been removed.
3001
3002*** X clipboard managers are now supported.
3003To inhibit this, change `x-select-enable-clipboard-manager' to nil.
3004
3005** New command `C-x r N' (`rectangle-number-lines') numbers the lines
3006in the current rectangle. With a prefix argument, this prompts for a
3007number to count from and for a format string.
3008
3009** `redisplay-dont-pause' now defaults to t.
3010This makes Emacs feel more responsive to editing commands that arrive
3011at high rate, e.g. if you lean on some key, because stopping redisplay
3012in the middle (when this variable is nil) forces more expensive
3013updates later on, and Emacs appears to be unable to keep up.
3014
3015** The behavior of <TAB> for active regions in Text mode has changed.
3016In Text and related modes, typing <TAB> (`indent-for-tab-command')
3017when the region is active causes Emacs to indent all the lines in the
3018region, aligning them with the line previous to the first line in the
3019region (or with the left margin if there is no previous line).
3020
3021** When `occur' is called with a prefix argument, matching strings are
3022collected into the `*Occur*' buffer without line numbers. If there
3023are parenthesized subexpressions in the specified regexp, `occur'
3024reads replacement text that may contain \\& and \\N whose convention
3025follows `replace-match'.
3026
3027
3028* Changes in Specialized Modes and Packages in Emacs 24.1
3029
3030** Archive Mode has basic support for browsing and updating 7z archives.
3031
3032** BibTeX mode
3033
3034*** BibTeX mode now supports biblatex.
3035Use the variable `bibtex-dialect' to select different BibTeX dialects.
3036`bibtex-entry-field-alist' is now an obsolete alias for
3037`bibtex-BibTeX-entry-alist'.
3038
3039*** New command `bibtex-search-entries', bound to C-c C-a.
3040
3041*** New `bibtex-entry-format' option `sort-fields', disabled by default.
3042
3043*** New variable `bibtex-search-entry-globally'.
3044
3045** Browse-url
3046
3047*** New option `browse-url-mailto-function' specifies how to handle "mailto:"s.
3048
3049*** The default browser used by the package is now the "xdg-open" program,
3050on platforms that support it. This calls your desktop's preferred browser.
3051
3052** Calc
3053
3054*** Support for musical notes.
3055
3056*** Support for logarithmic units.
3057
3058*** No longer uses the tex prefix for TeX specific unit names when
3059using TeX or LaTeX mode.
3060
3061*** New option to highlight selections using faces.
3062
3063*** `calc-histogram' has the option of using a vector to determine the bins.
3064
3065*** New "O" option prefix.
3066
3067*** Use the "O" prefix to "d r" (`calc-radix') to turn on twos-complement mode.
3068
3069** Calendar, Diary, and Appt
3070
3071*** Diary entries can contain non-printing "comments".
3072See the variable `diary-comment-start'.
3073
3074*** Appointments can specify their individual warning times.
3075See the variable `appt-warning-time-regexp'.
3076
3077*** The function specified by `appt-disp-window-function' may be passed
3078lists of arguments if multiple appointments are due at similar times.
3079If you are using a custom function for this, you should update it.
3080
3081*** New function `diary-hebrew-birthday'.
3082
3083*** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array'
3084may no longer be nil, but must all be strings.
3085
3086*** The obsolete (since Emacs 22.1) method of enabling the appt
3087package by adding `appt-make-list' to `diary-hook' has been removed.
3088Use `appt-activate' instead.
3089
3090*** Some appt variables (obsolete since Emacs 22.1) have been removed:
3091appt-issue-message (use the function appt-activate)
3092appt-visible/appt-msg-window (use the variable appt-display-format)
3093
3094*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
3095view-diary-entries, list-diary-entries, show-all-diary-entries
3096
3097** CC Mode
3098
3099*** New feature to "guess" the style in an existing buffer.
3100The main entry point is M-x c-guess.
3101
3102*** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang).
3103
3104*** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes.
3105Thus C-M-a will, by default, go to the beginning of the immediate function,
3106not the top level.
3107
3108*** "Macros with semicolons" can be registered for correct indentation.
3109Where such a macro ends a line (no semicolon) the next statement is no longer
3110parsed as a statement continuation.
3111
3112** Comint and modes derived from it use the standard completion code.
3113
3114** Compilation mode
3115
3116*** Compilation mode can be used without Font Lock mode.
3117`compilation-parse-errors-function' is now obsolete.
3118
3119*** New variable `compilation-filter-start', which is bound while
3120`compilation-filter-hook' runs. It records the start position of the
3121text inserted by `compilation-filter'.
3122
3123*** `compilation-error-screen-columns' and `compilation-first-column'
3124are obeyed in the editing buffer. So programming language modes can
3125set them, whereas previously only the value in the *Compilation*
3126buffer was used.
3127
3128** Customize
3129
3130*** Customize buffers now contain a search field.
3131The search is performed using `customize-apropos'.
3132To turn off the search field, set `custom-search-field' to nil.
3133
3134*** Options in customize group buffers start out hidden if not customized.
3135Use the arrow to the left of the option name to toggle visibility.
3136
3137*** custom-buffer-sort-alphabetically now defaults to t.
3138
3139*** The color widget now has a "Choose" button, which allows you to
3140choose a color via `list-colors-display'.
3141
3142** D-Bus
3143
3144*** It is now possible to access buses other than the default system
3145or session bus.
3146
3147*** The `dbus-register-method' and `dbus-register-property' functions
3148optionally do not register names.
3149
3150*** The new function `dbus-register-service' registers a known service
3151name on a D-Bus without also registering a property or a method.
3152
3153** Dired-x
3154
3155*** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'),
3156if called with a prefix argument, read a file name from the minibuffer
3157instead of using the current buffer.
3158
3159*** The "dired local variables" feature of Dired-x is obsolete.
3160The standard directory local variables feature replaces it.
3161
3162** ERC changes
3163
3164*** New options `erc-autojoin-timing' and `erc-autojoin-delay',
3165controlling attempts to autojoin a channel.
3166
3167*** New variable `erc-coding-system-precedence': If we use `undecided'
3168as the server coding system, this variable will then be consulted.
3169The default is to decode strings that can be decoded as utf-8 as
3170utf-8, and do the normal `undecided' decoding for the rest.
3171
3172** Eshell changes
3173
3174*** The default value of `eshell-directory-name' has changed
3175to be an "eshell" directory in `user-emacs-directory'.
3176The old "~/.eshell/" directory is still used if it exists, though.
3177
3178** gdb-mi
3179
3180*** The M-x gdb command now uses the GDB Machine Interface protocol.
3181It now supports multithread non-stop debugging and simultaneous
3182debugging of several threads.
3183
3184** Image mode
3185
3186*** RET (`image-toggle-animation') toggles animation, if applicable.
3187Animation plays once, unless the option `image-animate-loop' is non-nil.
3188
3189** Info
3190
3191*** New command M-x info-display-manual displays a named Info manual.
3192If that manual is already visited in some Info buffer, it displays
3193that buffer. (This is handy if you have many manuals in many *info*
3194buffers, and don't remember the name of the buffer visiting the manual
3195you want to consult.) Otherwise, it loads and displays the manual.
3196
3197*** `e' is now bound to `end-of-buffer' rather than to `Info-edit'.
3198This is for compatibility with the stand-alone Info reader program,
3199and also because `Info-edit' is a rarely used command that is disabled
3200by default.
3201
3202** Mail mode changes (not Message mode)
3203
3204*** New command M-x mail-add-attachment for adding MIME attachments
3205
3206*** The command M-x mail-attach-file was renamed to M-x mail-insert-file.
3207(Its name is misleading, since it has nothing to do with MIME
3208attachments.) The old name is now an obsolete alias to the new name.
3209
3210** MH-E has been updated to MH-E version 8.3.1.
3211See MH-E-NEWS for details.
3212
3213** Modula-2 mode provides auto-indentation.
3214
3215** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
3216
3217** nXML mode no longer binds C-RET to `nxml-complete'.
3218Completion is now performed via `completion-at-point', bound to C-M-i
3219or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the
3220default), this performs tag completion.
3221
3222** Org mode has been updated to version 7.8.09.
3223See ORG-NEWS for details.
3224
3225** Prolog mode has been completely revamped, with lots of additional
3226functionality such as more intelligent indentation, electricity,
3227support for more variants, including Mercury, and a lot more.
3228
3229** Rmail
3230
3231*** The command `rmail-epa-decrypt' decrypts OpenPGP data
3232in the Rmail incoming message.
3233
3234*** The variable `rmail-message-filter' no longer has any effect.
3235This change was made in Emacs 23.1 but was not advertised at the time.
3236Try using `rmail-show-message-hook' instead.
3237
3238** Shell mode
3239
3240*** M-x shell prompts for the shell path name if the default directory
3241is a remote file name and neither the environment variable $ESHELL nor
3242the variable `explicit-shell-file-name' is set.
3243
3244*** TAB is now bound to the standard `completion-at-point' command,
3245which now implements the pcomplete rules for shell command completion.
3246
3247** SMTPmail
3248
3249*** SMTPmail now uses encrypted connections (via STARTTLS) by default
3250if the mail server supports them. This uses either built-in GnuTLS
3251support, or the starttls.el library. Customize `smtpmail-stream-type'
3252to change this.
3253
3254*** The variable `smtpmail-auth-credentials' has been removed.
3255By default, the information is now stored in the file ~/.authinfo.
3256This was the default value of smtpmail-auth-credentials. If you had
3257customized smtpmail-auth-credentials to a list of user names and
3258passwords, those settings are not used. During your first connection
3259to the smtp server, Emacs will prompt for the user name and password,
3260and offer to save them to ~/.authinfo. Or you can manually copy the
3261credentials to ~/.authinfo. For example, if you had
3262
3263 (setq smtpmail-auth-credentials
3264 '(("mail.example.org" 25 "jim" "s!cret")))
3265
3266then the equivalent line in ~/.authinfo would be
3267
3268 machine mail.example.org port 25 login jim password s!cret
3269
3270See the auth-source manual for more information, e.g. on encrypting
3271the credentials file.
3272
3273*** The variable `smtpmail-starttls-credentials' has been removed.
3274If you had that set, you need to put
3275
3276 machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert"
3277
3278in your ~/.authinfo file instead.
3279
3280*** SMTPmail defaults to using the address in the From: header as the
3281SMTP MAIL FROM envelope. To override this, set `mail-envelope-from'
3282to the address you wish to use instead.
3283
3284** SQL mode
3285
3286*** New options `sql-port', `sql-connection-alist', `sql-send-terminator',
3287and `sql-oracle-scan-on'.
3288
3289*** New options controlling prompting for login parameters.
3290Each supported product has a custom variable `sql-*-login-params',
3291which is a list of the parameters to be prompted for before a
3292connection is established.
3293
3294*** The command `sql-product-interactive' now takes a prefix argument,
3295which causes it to prompt for an SQL product.
3296
3297*** Product-specific SQL interactive commands now take prefix arguments.
3298These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.),
3299given a prefix argument, prompt for a name for the SQL interactive
3300buffer. This reduces the need for calling `sql-rename-buffer'.
3301
3302*** SQL interactive modes suppress command continuation prompts, and
3303replace tabs with spaces. The first change impacts multiple line SQL
3304statements entered with C-j between each line, statements yanked into
3305the buffer and statements sent with `sql-send-*' functions. The
3306second prevents the MySQL and Postgres interpreters from listing
3307object name completions when sent text via `sql-send-*' functions.
3308
3309*** New command `sql-connect' starts a predefined SQLi session,
3310using the login parameters from `sql-connection-alist'.
3311
3312*** New "Save Connection" menu item in SQLi buffers.
3313This gathers the login params specified for the SQLi session, if it
3314was not started by a connection, and saves them as a new connection.
3315
3316*** New commands for listing database objects and details:
3317sql-list-all and sql-list-table.
3318
3319*** An API for manipulating SQL product definitions has been added.
3320
3321** TeX modes
3322
3323*** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
3324
3325** Tramp
3326
3327*** New inline access method "ksu" (kerberized su).
3328
3329*** The following access methods are discontinued: "ssh1_old",
3330"ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish".
3331
3332*** The user option `remote-file-name-inhibit-cache' controls whether
3333remote file attributes are cached for better performance.
3334
3335*** The option `ange-ftp-binary-file-name-regexp' has changed its
3336default value to "".
3337
3338*** Handlers for `file-selinux-context' and `set-file-selinux-context'
3339for remote machines which support SELinux.
3340
3341** New function `url-queue-retrieve', which behaves like url-retrieve,
3342but with limits (`url-queue-parallel-processes', `url-queue-timeout') on
3343the degree of parallelism.
3344
3345** VC and related modes
3346
3347*** Support for pulling on distributed version control systems.
3348The command C-x v + (`vc-pull') runs a "pull" operation, if it is
3349supported (currently with Bzr, Git, and Mercurial), to update the
3350current branch and working tree. A prefix argument means to prompt
3351the user for specifics, e.g. a pull location.
3352
3353*** `vc-update' is now an alias for `vc-pull'.
3354
3355*** Support for merging on distributed version control systems.
3356The command C-x v m (`vc-merge') now runs a "merge" operation, if it
3357is supported (currently with Bzr, Git, and Mercurial), to merge
3358changes from another branch into the current one. It prompts for
3359specifics, e.g. a merge source.
3360
3361*** New option `vc-revert-show-diff' controls whether `vc-revert'
3362shows a diff while querying the user. It defaults to t.
3363
3364*** Log entries in some Log View buffers can be toggled to display a
3365longer description by typing RET (log-view-toggle-entry-display).
3366This is currently supported for Bzr, Git, and Mercurial (to support
3367another backend, define a `log-view-expanded-log-entry-function').
3368In the Log View buffers made by C-x v L (`vc-print-root-log'), you can
3369use this to display the full log entry for the revision at point.
3370
3371*** New command `vc-ediff' allows visual comparison of two revisions
3372of a file similar to `vc-diff', but using ediff backend.
3373
3374*** The option `vc-initial-comment' was removed in Emacs 23.2, but
3375this was not advertised at the time.
3376
3377*** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'.
3378Since Emacs 23, it has done the same thing as `toggle-read-only', but
3379this was not advertised at the time.
3380
3381** Obsolete modes
3382
3383*** abbrevlist.el
3384
3385*** erc-hecomplete.el (use erc-pcomplete.el instead)
3386
3387*** partial-completion-mode (complete.el) is obsolete.
3388You can get a comparable behavior with:
3389(setq completion-styles '(partial-completion initials))
3390(setq completion-pcm-complete-word-inserts-delimiters t)
3391
3392*** pc-mode.el is obsolete (CUA mode is much more comprehensive).
3393
3394*** pgg is obsolete (use EasyPG instead).
3395
3396*** sregex.el is obsolete, since rx.el is a strict superset.
3397
3398*** s-region.el and pc-select.el are obsolete.
3399They are superseded by shift-select-mode, enabled by default since 23.1.
3400
3401*** vc-mcvs.el is obsolete (for lack of a maintainer).
3402
3403** Miscellaneous
3404
3405*** The Landmark game is now invoked with `landmark', not `lm'.
3406Its functions and variables have been similarly renamed.
3407
3408*** In `ido-file-completion-map', C-v is no longer bound to `ido-toggle-vc'.
3409(This interfered with cua-mode.)
3410
3411*** f90.el has some support for Fortran 2008 syntax.
3412
3413*** `copyright-fix-years' can optionally convert consecutive years to ranges.
3414
3415*** New command `nato-region' converts text to NATO phonetic alphabet.
3416
3417
3418* New Modes and Packages in Emacs 24.1
3419
3420** Occur Edit mode applies edits made in *Occur* buffers to the
3421original buffers. It is bound to "e" in Occur mode.
3422
3423** New global minor mode electric-pair-mode.
3424When enabled, typing an open parenthesis automatically inserts the
3425matching closing one.
3426
3427** New global minor mode electric-indent-mode.
3428When enabled, typing certain characters triggers reindentation.
3429Major modes wishing to use this can set electric-indent-chars or
3430electric-indent-functions.
3431
3432** New global minor mode electric-layout-mode.
3433When enabled, typing certain characters automatically inserts newlines.
3434Major modes wishing to use this can set electric-layout-rules.
3435
3436** tabulated-list.el provides a generic major mode for tabulated data,
3437from which other modes can be derived.
3438
3439** pcase.el provides the ML-style pattern matching macro `pcase'.
3440
3441** secrets.el is an implementation of the Secret Service API, an
3442interface to password managers like GNOME Keyring or KDE Wallet. The
3443Secret Service API requires D-Bus for communication. The command
3444`secrets-show-secrets' offers a buffer with a visualization of the
3445secrets.
3446
3447** notifications.el provides an implementation of the Desktop
3448Notifications API. It requires D-Bus for communication.
3449
3450** soap-client.el supports access to SOAP web services from Emacs.
3451soap-inspect.el is an interactive inspector for SOAP WSDL structures.
3452
3453** New generic mode, xmodmap-generic-mode, for xmodmap files.
3454
3455** New emacs-lock.el package.
3456The previous version has been moved to obsolete/old-emacs-lock.el.
3457Now, there is a proper minor mode `emacs-lock-mode'. Protection
3458against exiting Emacs and killing the buffer can be set separately.
3459The mechanism for automatically turning off protection for buffers
3460with dead inferior processes has been generalized.
3461
3462
3463* Incompatible Lisp Changes in Emacs 24.1
3464
3465** Passing a nil argument to a minor mode function call now ENABLES
3466the minor mode unconditionally. This is so that you can write e.g.
3467
3468 (add-hook 'text-mode-hook 'foo-mode)
3469
3470to enable foo-mode in Text mode buffers, removing the need for
3471`turn-on-foo-mode' style functions. This affects all mode commands
3472defined by `define-minor-mode'. If called interactively, the mode
3473command still toggles the minor mode.
3474
3475** The return value of `backup-buffer' has changed.
3476It is now a list of three elements, where the second element is a list
3477describing the original file's SELinux context. If Emacs or the
3478system lacks SELinux support, the context list is (nil nil nil nil).
3479See "Basic SELinux support" above, under "Changes in Emacs 24.1".
3480
3481** `char-direction-table' and the `char-direction' function were deleted.
3482They were buggy and inferior to the new support of bidirectional
3483editing introduced in Emacs 24. If you need the bidirectional
3484properties of a character, use `get-char-code-property' with the last
3485argument `bidi-class'.
3486
3487** `copy-directory' now copies the source directory as a subdirectory
3488of the target directory, if the latter is an existing directory. The
3489new optional arg COPY-CONTENTS, if non-nil, makes the function copy
3490the contents directly into a pre-existing target directory.
3491
3492** For mouse click input events in the text area, the Y pixel
3493coordinate in the POSITION list now counts from the top of the text
3494area, excluding any header line. Previously, it counted from the top
3495of the header line.
3496
3497** Support for "old-style" backquotes, obsolete for 10+ years, has
3498been further reduced. Now a backquote not followed by a space is
3499always treated as a "new-style" backquote. Please remove all
3500"old-style" backquotes from your code. If your code uses backquotes
3501as documented in the Elisp manual, and compiles without warning, then
3502you have nothing to do in this regard. Code not following the
3503appropriate conventions may fail to compile.
3504
3505The most common cause of trouble seems to be an old-style backquote
3506followed by a newline. Another cause of trouble is vector notation
3507for key sequence notation: instead of [(control ,)] and [(control ')],
3508you should write [(control ?,)] and [(control ?')], which will work in
3509older Emacsen too.
3510
3511** The macro `eval-at-startup' was removed in Emacs 23.2, but this
3512was not advertised at the time. The function `custom-initialize-delay'
3513replaced all known uses.
3514
3515** `view-buffer' now treats special mode-class in the same way that
3516`view-file' has since Emacs 22 (i.e. it won't enable View mode if the
3517major mode is special).
3518
3519** Menu and tool bar changes
3520
3521*** During startup, Emacs no longer adds entries for `menu-bar-lines'
3522and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'.
3523With these alist entries omitted, `make-frame' checks the value of the
3524variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create
3525a menu-bar or tool-bar, respectively. If the alist entries are added,
3526they override the value of `menu-bar-mode'/`tool-bar-mode'.
3527
3528*** The menu bar bindings's caches are not used any more.
3529Use (where-is-internal <def> nil t) instead.
3530
3531** Regions created by mouse dragging are now normal active regions,
3532similar to those created by shift-selection (see Selection changes
3533above). In previous Emacs versions, these regions were delineated by
3534`mouse-drag-overlay'; that variable has been removed.
3535
3536** The fourth argument of `filter-buffer-substring' has been removed.
3537If you want to remove text properties from the final result, simply
3538pass the result through substring-no-properties.
3539
3540** cl.el no longer provides `cl-19'.
3541
3542** The following obsolete functions and aliases have been removed
3543(the appropriate new function is given in parentheses; "not needed"
3544means you can just remove all calls to the function in question):
3545
3546*** `comint-kill-output' (`comint-delete-output')
3547*** `decompose-composite-char' (`char-to-string')
3548*** `outline-visible' (`outline-invisible-p')
3549*** `internal-find-face' (`facep')
3550*** `internal-get-face' (`facep and check-face')
3551*** `frame-update-faces' (not needed)
3552*** `frame-update-face-colors' (`frame-set-background-mode')
3553*** `x-frob-font-weight' and `x-frob-font-slant' (`make-face-*' functions)
3554*** `x-make-font-bold' and `x-make-font-demibold' (`make-face-bold')
3555*** `x-make-font-italic' and `x-make-font-oblique' (`make-face-italic')
3556*** `x-make-font-bold-italic' (`make-face-bold-italic')
3557*** `x-make-font-unbold' (`make-face-unbold')
3558*** `x-make-font-unitalic' (`make-face-unitalic')
3559*** `mldrag-drag-mode-line' (`mouse-drag-mode-line')
3560*** `mldrag-drag-vertical-line' (`mouse-drag-vertical-line')
3561*** `iswitchb-default-keybindings' (`iswitchb-mode')
3562*** `char-bytes' (== 1)
3563*** `isearch-return-char' (`isearch-printing-char')
3564*** `make-local-hook' (not needed)
3565*** `set-screen-height' (`set-frame-height')
3566*** `set-screen-width' (`set-frame-width')
3567
3568** The following obsolete variables and varaliases have been removed
3569(the appropriate new variable is given in parentheses):
3570
3571*** `checkdoc-minor-keymap' (`checkdoc-minor-mode-map')
3572*** `vc-header-alist' (`vc-BACKEND-header')
3573*** `directory-sep-char' (== ?/)
3574*** `font-lock-defaults-alist' (`font-lock-defaults')
3575*** `e' (`float-e').
3576
3577** The following obsolete files were removed:
3578sc.el, x-menu.el, rnews.el, rnewspost.el
3579
3580** The format of the finder-inf.el file has changed, since the Finder
3581mechanism is now based on the package system. The variable
3582`finder-package-info' is replaced by `package--builtins' and
3583`finder-keywords-hash'.
3584
3585** When generating autoloads, `update-directory-autoloads' no longer
3586assumes every inspected file is in your `load-path'. It instead
3587generates relative names according to the current `load-path'.
3588
3589
3590* Lisp Changes in Emacs 24.1
3591
3592** Code can now use lexical scoping by default instead of dynamic scoping.
3593The `lexical-binding' variable enables lexical scoping for local
3594variables. It is typically set via a file-local variable in the first
3595line of the file, in which case it applies to all the code in that
3596file.
3597
3598*** `eval' takes a new optional argument `lexical' to choose the new lexical
3599binding instead of the old dynamic binding mode.
3600
3601*** Lexically scoped interpreted functions are represented with a new form
3602of function value which looks like (closure ENV ARGS &rest BODY).
3603
3604*** New macro `letrec' to define recursive local functions.
3605
3606*** `defvar' and `defconst' now mark the variable as special (dynamic).
3607So do `defcustom' and other forms that call `defvar' as a subroutine.
3608
3609*** New function `special-variable-p' to check whether a variable is
3610declared as dynamically bound.
3611
3612*** The form ((lambda ...) ...) is deprecated.
3613
3614** An Emacs Lisp testing tool is now included.
3615Emacs Lisp developers can use this tool to write automated tests for
3616their code. See the ERT info manual for details.
3617
3618** Changes for bidirectional display and editing
3619
3620*** New function `current-bidi-paragraph-direction'.
3621This returns the base direction of the paragraph at point.
3622
3623*** New function `bidi-string-mark-left-to-right'.
3624Given a string containing characters from right-to-left scripts, this
3625function returns another string which can be safely inserted into a
3626buffer, such that any following text will be always displayed to the
3627right of that string. (This works by appending an invisible Unicode
3628"LEFT-TO-RIGHT MARK" character if the argument string might need it.)
3629
3630This is useful when the buffer has overall left-to-right paragraph
3631direction and you need to insert a string whose contents are not known
3632in advance, without disrupting the layout of the line.
3633
3634** Window changes
3635
3636*** Window tree functions are accessible in Elisp.
3637Functions are provided to return the parent, siblings or child windows
3638of any window including internal windows (windows not associated with a
3639buffer) in the window tree.
3640
3641**** New function `window-valid-p' gives non-nil for live and internal
3642windows.
3643
3644**** Window manipulation can deal with internal windows.
3645Many window handling functions like `split-window', `delete-window', or
3646`delete-other-windows' as well as the window resizing functions can now
3647act on any window including internal ones.
3648
3649*** window-total-height/-width vs window-body-height/-width.
3650The function `window-height' has been renamed to `window-total-height'
3651and `window-width' has been renamed to `window-body-width'. The old
3652names are provided as aliases. Two new functions `window-total-width'
3653and `window-body-height' are provided.
3654
3655*** Window parameters specific to window handling functions.
3656For each window you can specify a parameter to override the default
3657behavior of a number of functions like `split-window', `delete-window'
3658and `delete-other-windows'. The variable `ignore-window-parameters'
3659allows to ignore processing such parameters.
3660
3661*** New semantics of third argument of `split-window'.
3662The third argument of `split-window' has been renamed to SIDE and can be
3663set to any of the values 'below, 'right, 'above, or 'left to make the
3664new window appear on the corresponding side of the window that shall be
3665split. Any other value of SIDE will cause `split-window' to split the
3666window into two side-by-side windows as before.
3667
3668*** Window resizing functions.
3669A new standard function for resizing windows called `window-resize' has
3670been introduced. This and all other functions for resizing windows no
3671longer delete any windows when they become too small.
3672
3673*** Deleting the selected window now selects the most recently selected
3674live window on that frame instead.
3675
3676*** `adjust-window-trailing-edge' adjustments.
3677`adjust-window-trailing-edge' can now deal with fixed-size windows and
3678is able to resize other windows if a window adjacent to the trailing
3679edge cannot be shrunk any more. This makes its behavior more similar to
3680that of Emacs 21 without compromising, however, its inability to delete
3681windows which was introduced in Emacs 22.
3682
3683*** Window-local buffer lists.
3684Windows now have local buffer lists. This means that removing a buffer
3685from display in a window will preferably show the buffer previously
3686shown in that window with its previous window-start and window-point
3687positions. This also means that the same buffer may be automatically
3688shown twice even if it already appears in another window.
3689
3690*** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW,
3691which if non-nil requires the buffer to be displayed in the currently
3692selected window, signaling an error otherwise. If nil, another window
3693can be used, e.g. if the selected one is strongly dedicated.
3694
3695*** `split-window-vertically' and `split-window-horizontally' renamed
3696to `split-window-below' and `split-window-right' respectively.
3697The old names are kept as aliases.
3698
3699*** Display actions
3700
3701**** The second arg to `display-buffer' and `pop-to-buffer' is now
3702named ACTION, and takes a display action of the same form as
3703`display-buffer-base-action' (see Changes, above). A non-nil,
3704non-list value is treated specially, as the old meaning.
3705
3706**** New variable `display-buffer-overriding-action'.
3707
3708**** The procedure of `display-buffer' etc. to choose a window is
3709determined by combining `display-buffer-overriding-action',
3710`display-buffer-alist', the ACTION arg, `display-buffer-base-action',
3711and `display-buffer-fallback-action'. The second and fourth of these
3712are user-customizable variables.
3713
3714See the docstring of `display-buffer' for details.
3715
3716*** New functions `window-state-get' and `window-state-put'.
3717These functions allow to save and restore the state of an arbitrary
3718frame or window as an Elisp object.
3719
3720** Completion
3721
3722*** New variable `completion-extra-properties' used to specify extra
3723properties of the current completion:
3724- :annotate-function, same as the old completion-annotate-function.
3725- :exit-function, function to call after completion took place.
3726
3727*** Functions on `completion-at-point-functions' can return any of the
3728properties valid for `completion-extra-properties'.
3729
3730*** `completion-annotate-function' is obsolete.
3731
3732*** New `metadata' method for completion tables. The metadata thus returned
3733can specify various details of the data returned by `all-completions':
3734- `category' is the kind of objects returned (e.g., `buffer', `file', ...),
3735 used to select a style in completion-category-overrides.
3736- `annotation-function' to add annotations in *Completions*.
3737- `display-sort-function' to specify how to sort entries in *Completions*.
3738- `cycle-sort-function' to specify how to sort entries when cycling.
3739
3740*** `minibuffer-local-filename-must-match-map' is not used any more.
3741Instead, the bindings in `minibuffer-local-filename-completion-map'
3742are combined with `minibuffer-local-must-match-map'.
3743
3744*** New variable `completing-read-function' allows overriding the
3745behavior of `completing-read'.
3746
3747** `glyphless-char-display' can now distinguish between graphical and
3748text terminal display, via a char-table entry that is a cons cell.
3749
3750** `pre-command-hook'/`post-command-hook' are not reset to nil on error.
3751Instead, the offending function is removed.
3752
3753** New hook types
3754
3755*** New function `run-hook-wrapped' for running an abnormal hook by
3756passing the hook functions as arguments to a "wrapping" function.
3757Like `run-hook-with-args-until-success', it stops at the first
3758non-nil return value.
3759
3760*** New macro `with-wrapper-hook' for running an abnormal hook as a
3761set of "wrapping" filters, similar to around advice.
3762(A version of this macro was actually added in Emacs 23.2 but was not
3763advertised at the time.)
3764
3765** Debugger changes
3766
3767*** New macro `condition-case-unless-debug' (this was actually added in
3768Emacs 23.1 as condition-case-no-debug, but not advertised)
3769
3770*** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised.
3771
3772*** Variable `stack-trace-on-error' removed.
3773
3774*** The debugger can now "continue" from an error, which means it will
3775jump to the error handler as if the debugger had not been invoked
3776instead of jumping all the way to the top-level.
3777
3778*** Set `debug-on-event' to enter the debugger on events like SIGUSR1.
3779This can be useful when `inhibit-quit' is set.
3780
3781** The new function `server-eval-at' allows evaluation of Lisp forms on
3782named Emacs server instances.
3783
3784** `call-process' and `call-process-region' allow a `(:file "file")' spec
3785to redirect STDOUT to a file.
3786
3787** The function `format-time-string' now supports the %N directive,
3788for higher-resolution time stamps.
3789
3790** New input reading functions
3791
3792*** New function `read-char-choice' reads a restricted set of
3793characters, discarding any inputs not inside the set.
3794
3795*** The command `read-color' now requires a match for a color name
3796or RGB triplet, instead of signaling an error if the user provides
3797invalid input.
3798
3799**** `facemenu-read-color' is now an alias for `read-color'.
3800
3801** `image-library-alist' is renamed to `dynamic-library-alist'.
3802The variable is now used to load all kind of supported dynamic libraries,
3803not just image libraries. The previous name is still available as an
3804obsolete alias.
3805
3806** Syntax parsing changes
3807
3808*** New variable `syntax-propertize-function'.
3809This replaces `font-lock-syntactic-keywords' which is now obsolete.
3810This allows syntax-table properties to be set independently from font-lock:
3811just call syntax-propertize to make sure the text is propertized.
3812Together with this new variable come a new hook
3813syntax-propertize-extend-region-functions, as well as two helper functions:
3814syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
3815as-is; and syntax-propertize-rules which provides a new way to specify
3816syntactic rules.
3817
3818*** Syntax tables support a new "comment style c" additionally to style b.
3819
3820** New hook `post-self-insert-hook', run after `self-insert-command'.
3821
3822** frame-local variables cannot be let-bound any more.
3823
3824** Major and minor mode changes
3825
3826*** `set-auto-mode' now respects mode: local variables at the end of files,
3827as well as those in the -*- line.
3828
3829*** `prog-mode' is a new major mode from which programming modes
3830should be derived.
3831
3832**** `prog-mode-hook' can be used to enable features for programming
3833modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable
3834on-the-fly spell checking for comments and strings.
3835
3836*** New hook `change-major-mode-after-body-hook', run by
3837`run-mode-hooks' just before any other mode hooks.
3838
3839*** Enabled globalized minor modes can be disabled in specific major modes.
3840If the global mode is global-FOO-mode, then run (FOO-mode -1) in the
3841major mode's hook, where FOO-mode toggles the mode on a per-buffer basis.
3842
3843*** `define-minor-mode' accepts new keywords :variable, :after-hook.
3844
3845** File-handling changes
3846
3847*** `delete-file' and `delete-directory' now accept optional arg TRASH.
3848Trashing is performed if TRASH and `delete-by-moving-to-trash' are
3849both non-nil. Interactively, TRASH defaults to t, unless a prefix
3850argument is supplied (see Trash changes, above).
3851
3852*** New file predicates: `file-equal-p', `file-in-directory-p'.
3853
3854** Tool-bars can display separators.
3855Tool-bar separators are handled like menu separators in menu-bar maps,
3856i.e. via menu entries of the form `(menu-item "--")'.
3857
3858** Image API
3859
3860*** Animated images support (currently animated gifs only).
3861
3862**** `image-animated-p' returns non-nil if an image can be animated.
3863
3864**** `image-animate' animates a supplied image spec.
3865
3866**** `image-animate-timer' returns the timer object for an image that
3867is being animated.
3868
3869*** `image-extension-data' has been renamed to `image-metadata'.
3870The old name is an obsolete alias to the new one.
3871
3872*** Image mode can view any image type that ImageMagick supports.
3873This requires Emacs to be built with ImageMagick support.
3874
3875**** New function `imagemagick-types', defined if ImageMagick support
3876is enabled, returns a list of image file extensions that your
3877ImageMagick installation supports.
3878
3879**** New function `imagemagick-register-types' enables ImageMagick
3880image types in Image mode and in `create-image' and other helper
3881functions.
3882
3883**** New option `imagemagick-types-inhibit' excludes certain
3884ImageMagick image types from `imagemagick-register-types'.
3885
3886**** With ImageMagick support, there are extra Image mode commands to
3887resize and rotate images: `image-transform-fit-to-height',
3888`image-transform-fit-to-width', `image-transform-set-rotation', and
3889`image-transform-set-scale'.
3890
3891** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and
3892passes it to the mail user agent function. This argument specifies an
3893action for returning to the caller after finishing with the mail. For
3894example, this is used by Rmail to optionally delete a mail window.
3895
3896** XML and HTML parsing
3897If Emacs is compiled with libxml2 support, there are two new
3898functions: `libxml-parse-html-region' (which parses "real world" HTML)
3899and `libxml-parse-xml-region' (which parses XML). Both return an
3900Emacs Lisp parse tree.
3901
3902** Networking and encryption changes
3903
3904*** `open-network-stream' can now be used to open an encrypted stream.
3905It now accepts an optional `:type' parameter for initiating a TLS
3906connection, directly or via STARTTLS. To do STARTTLS, additional
3907parameters (`:end-of-command', `:success', `:capabilities-command')
3908must also be supplied.
3909
3910*** New library gnutls.el.
3911The new function `gnutls-available-p' returns non-nil if Emacs is
3912built with GnuTLS support. The main entry points are
3913`open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use
3914these functions through `open-network-stream', because that can
3915upgrade connections through STARTTLS opportunistically or use plain
3916SSL, depending on your needs. For debugging, set `gnutls-log-level'
3917greater than 0.
3918
3919*** New primitive `secure-hash' that supports many secure hash algorithms:
3920md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library
3921sha1.el has been removed. The `sha1' feature is provided by default.
3922
3923** Isearch
3924
3925*** New hook `isearch-update-post-hook' that runs in `isearch-update'.
3926
3927** Progress reporters can now "spin".
3928The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
3929now be nil, or omitted. This makes a "non-numeric" reporter. Each
3930time you call `progress-reporter-update' on that progress reporter,
3931with a nil or omitted VALUE argument, the reporter message is
3932displayed with a "spinning bar".
3933
3934** New variable `revert-buffer-in-progress-p' is true while a buffer is
3935being reverted, even if the buffer has a local `revert-buffer-function'.
3936
3937** New variables `delayed-warnings-list' and `delayed-warnings-hook'.
3938If delayed-warnings-list is non-nil, the command loop calls
3939`delayed-warnings-hook' after `post-command-hook'. At present, this
3940is only used by Emacs on some platforms to display warnings during
3941startup, which might otherwise not be noticed. This uses the
3942functions `display-delayed-warnings' and `collapse-delayed-warnings'.
3943
3944** rx.el has a new `group-n' construct for explicitly numbered groups.
3945
3946** New function `make-composed-keymap' that constructs a new keymap
3947from multiple input maps. You can use this to make a keymap that
3948inherits from multiple maps, eg:
3949 (set-keymap-parent newmap (make-composed-keymap othermap parent))
3950
3951** New function `string-prefix-p'.
3952(This was actually added in Emacs 23.2 but was not advertised at the time.)
3953
3954** New reader macro ## that stands for the empty symbol.
3955This means that the empty symbol can now be read back. Also, #: by itself
3956(when not immediately followed by a possible symbol character) stands for
3957an empty uninterned symbol.
3958
3959** New math functions `isnan', `copysign', `frexp', `ldexp'.
3960
3961** The following functions and variables are obsolete:
3962
3963*** `tooltip-use-echo-area' is obsolete.
3964Rather than setting this to t, disable Tooltip mode instead.
3965
3966*** buffer-substring-filters is obsolete.
3967Use `filter-buffer-substring-functions' instead.
3968
3969*** `byte-compile-disable-print-circle' is obsolete.
3970
3971*** `deferred-action-list' and `deferred-action-function' are obsolete.
3972Use `post-command-hook' instead.
3973
3974*** `font-lock-maximum-size' is obsolete.
3975
3976
3977* Changes in Emacs 24.1 on Non-Free Operating Systems
3978
3979** On MS Windows, Emacs warns when using the obsolete init file _emacs,
3980and also when HOME is set to C:\ by default.
3981
3982** New configure.bat options
3983
3984*** --enable-checking builds Emacs with extra runtime checks.
3985
3986*** --distfiles specifies files to be included in binary distribution.
3987
3988*** --without-gnutls disables automatic GnuTLS detection.
3989
3990*** --lib for general library linkage, works with the USER_LIBS build variable.
3991
3992** New make target `dist' to create binary distribution for MS Windows.
3993
3994** The Lisp function `w32-default-color-map' is now obsolete.
3995(It is only used internally in the Emacs C code.)
3996
3997** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but
3998reappear on mouse-over. (Requires OS X 10.6 or later.)
3999
4000** On Mac OS X, dragging a file into Emacs visits the file, like on
4001other platforms, rather than inserting its contents into the buffer.

18* Installation Changes in Emacs 24.4
19
20** Emacs can now be compiled with ACL (access control list) support.
21This happens by default if a suitable support library is found at
22build time, like libacl on GNU/Linux. To prevent this, use the
23configure option `--disable-acl'. See below for the features this provides.
24
25** Emacs can now be compiled with file notification support.
26This happens by default if a suitable system library is found at
27build time. To prevent this, use the configure option
28`--without-file-notification'. See below for file-notify features.
29This feature is not available for the Nextstep port.
30
31** Emacs can now be compiled with zlib support.
32This happens by default if zlib is present, which it normally is.
33To prevent this, use the configure option `--without-zlib'.
34This provides the function `zlib-decompress-region'; see below for details.
35
36** The configure option `--without-compress-info' has been generalized,
37and renamed to `--without-compress-install'. It now prevents compression
38of _any_ files during installation.
39
40** The configure option `--with-crt-dir' has been removed.
41It is no longer needed, as the crt*.o files are no longer linked specially.
42
43** Directories passed to configure option `--enable-locallisppath' are
44no longer created during installation.
45
46** Emacs for Nextstep (Mac OS X, GNUstep) can be built with ImageMagick support.
47This requires pkg-config to be available at build time.
48
49
50* Startup Changes in Emacs 24.4
51
52** When initializing `load-path', an empty element in the EMACSLOADPATH
53environment variable (either leading, e.g., ":/foo"; trailing, e.g.,
54"/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default
55load-path (the one that would have been used if EMACSLOADPATH was unset).
56This makes it easier to _extend_ the load-path via EMACSLOADPATH
57(previously, EMACSLOADPATH had to specify the complete load-path,
58including the defaults). (In older versions of Emacs, an empty element
59was replaced by ".", so use an explicit "." now if that is what you want.)
60
61** The -L option, which normally prepends its argument to load-path,
62will instead append, if the argument begins with `:' (or `;' on MS Windows;
63i.e., `path-separator').
64
65** If you use either site-load.el or site-init.el to customize the dumped
66Emacs executable, any changes to `load-path' that these files make
67will no longer be present after dumping. To affect a permanent change
68to `load-path', use the `--enable-locallisppath' option of `configure'.
69
70** The user option `initial-buffer-choice' can now specify a function
71to set up the initial buffer.
72
73
74* Changes in Emacs 24.4
75
76** Support for ACLs (access control lists).
77This requires a suitable support library to be found at build time.
78On GNU/Linux, the POSIX ACL interface is used via libacl.
79On MS-Windows, the NT Security APIs are used to emulate the POSIX interface.
80ACLs are extended file attributes, used e.g. for finer-grained permissions.
81
82*** Emacs preserves the ACL entries of files when backing up.
83
84*** New functions `file-acl' and `set-file-acl' get and set file ACLs.
85
86** Support for menus on text-mode terminals.
87If the terminal supports a mouse, clicking on the menu bar, or on
88sensitive portions of the mode line or header line, will drop down the
89menu defined at that position. Likewise, clicking C-mouse-1, C-mouse-2, or
90C-mouse-3 on the text area will pop up the menus defined for those locations.
91
92If the text terminal does not support a mouse, you can activate the
93first menu-bar menu by typing F10, which invokes `menu-bar-open'.
94
95If you want the previous behavior, where F10 invoked `tmm-menubar',
96customize the option `tty-menu-open-use-tmm' to a non-nil value.
97(Typing M-` always invokes `tmm-menubar', even if `tty-menu-open-use-tmm'
98is nil.)
99
100** New option `load-prefer-newer' affects how the `load' function chooses
101the file to load. If this is non-nil, then when both .el and .elc
102versions of a file exist, and the caller did not explicitly specify
103which one to load, then the newer file is loaded. The default, nil,
104means to always load the .elc file.
105
106** Multi-monitor support
107
108*** New functions `display-monitor-attributes-list' and
109`frame-monitor-attributes' can be used to obtain information about
110each physical monitor on multi-monitor setups.
111
112*** The functions `display-pixel-width' and `display-pixel-height' now
113behave consistently among the platforms: they return the pixel width
114or height for all physical monitors associated with the given display
115as if they were on X. To get information for each physical
116monitor, use the new functions above. Similar notes also apply to
117`x-display-pixel-width', `x-display-pixel-height', `display-mm-width',
118`display-mm-height', `x-display-mm-width', and `x-display-mm-height'.
119
120** New function `zlib-decompress-region', which decompresses gzip- and
121zlib-format compressed data using built-in zlib support (if available).
122
123** The *Messages* buffer is created in `messages-buffer-mode',
124a new major mode, with read-only status. Any code that might create
125the *Messages* buffer should call the function `messages-buffer' to do
126so and set up the mode.
127
128** The cursor stops blinking after 10 blinks (by default) on X and Nextstep.
129You can change the default by customizing `blink-cursor-blinks'.
130
131** In keymaps where SPC scrolls forward, S-SPC now scrolls backward.
132This affects View mode, etc.
133
134** The default value of `make-backup-file-name-function' is no longer nil.
135Instead it defaults to a function that does what the nil value used to.
136
137** Help
138
139*** The command `apropos-variable' is renamed to `apropos-user-option'.
140`apropos-user-option' shows all user options, while `apropos-variable'
141shows all variables. When called with a universal prefix argument,
142the two commands swap their behaviors. When `apropos-do-all' is
143non-nil, they output the same results.
144
145*** The key `?' now describes prefix bindings, like `C-h'.
146
147*** The command `describe-function' has been extended for EIEIO.
148Running it on constructors will show a full description of the
149generated class. For generic functions, it will show all
150implementations together with links to the source. The old commands
151`describe-class', `describe-constructor' and `describe-generic' were
152removed.
153
154*** The function `quail-help' is no longer an interactive command.
155Use `C-h C-\' (`describe-input-method') instead.
156
157** Frame and window handling
158
159*** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized',
160bound to <f11> and M-<f10>, respectively.
161
162*** New hooks `focus-in-hook', `focus-out-hook'.
163These are normal hooks run when an Emacs frame gains or loses input focus.
164
165*** The function `window-in-direction' now takes additional arguments
166for specifying a reference point, wrapping the selection around frame
167borders, and specifying ways to select the minibuffer window.
168
169*** Emacs can now change frame sizes in units of pixels, rather than
170text rows or columns. When maximizing a frame or making it fullscreen,
171remaining extra pixels are no longer given to the minibuffer, the rightmost
172fringe, or other unusable space, but are distributed among the text
173areas of the frame's windows. If the new option `frame-resize-pixelwise'
174is non-nil, all frame size changes happen pixelwise and set the
175corresponding size hints for the window manager.
176
177*** Emacs can now change window sizes in units of pixels.
178Mouse-dragging a mode line or window divider now changes the size of
179adjacent windows pixelwise. If the new option `window-resize-pixelwise'
180is non-nil, functions like `balance-windows-area' and `fit-window-to-buffer'
181resize windows pixelwise. Most functions for changing or accessing
182window sizes now have an additional argument that allows changes to apply,
183or values to be returned, in pixels instead of lines/columns.
184
185*** The functions `window-body-height' and `window-body-width' now never
186count partially visible lines or columns if called with a nil PIXELWISE
187argument.
188
189*** Emacs can now draw dividers between adjacent windows. To put
190dividers between side-by-side/vertically stacked windows customize the
191frame parameters `right-divider-width' and `bottom-divider-width' to
192some positive integer. You can drag dividers with the mouse (they show
193a corresponding cursor when the mouse hovers over them). You can change
194the appearance of dividers by customizing the faces `window-divider',
195`window-divider-first-pixel', and `window-divider-last-pixel'. The last
196two are useful to provide a 3D effect, or to better distinguish dividers
197from surrounding display objects.
198
199*** New functions to return the pixel sizes of window components, namely
200`window-scroll-bar-width', `window-mode-line-height',
201`window-header-line-height', `window-right-divider-width', and
202`window-bottom-divider-width'.
203
204*** The new function `window-text-pixel-size' returns the size of the
205text of a window's buffer in pixels. This allows functions like
206`fit-frame-to-buffer' and `fit-window-to-buffer' to accurately fit a
207window to its buffer as it will be displayed.
208
209*** `fit-window-to-buffer' can now resize windows in both dimensions.
210This behavior is controlled by the new option
211`fit-window-to-buffer-horizontally'. The new option
212`fit-frame-to-buffer' allows you to fit the window's frame to its buffer.
213
214*** `fit-frame-to-buffer' now fits frames in both dimensions. The new
215options `fit-frame-to-buffer-margins' and `fit-frame-to-buffer-sizes'
216control the size of the frame and its position on screen.
217
218*** Temp Buffer Resize Mode can now adjust the height and width of
219windows and frames. The new option `temp-buffer-max-width' allows you to
220control the width of temporary buffer windows. Moreover, if the new
221option `fit-frame-to-buffer' is non-nil and the buffer appears in the
222root window of a frame, Temp Buffer Resize Mode will try to adjust the
223width and/or height of the frame.
224
225*** `split-window' is now a non-interactive function, not a command.
226As a command, it was a special case of `C-x 2' (`split-window-below'),
227and as such superfluous. After being reimplemented in Lisp, its
228interactive form was mistakenly retained.
229
230*** The functions `window-size' and `window-total-size' now have an
231optional argument to return a rounded size value.
232
233*** `window-state-put' now allows you to put a window state into internal
234windows too.
235
236*** New option `scroll-bar-adjust-thumb-portion'.
237Available only on X, this option allows you to control over-scrolling
238using the scroll bar (i.e., dragging the thumb down even when the end
239of the buffer is visible).
240
241*** New display actions functions for `display-buffer':
242
243**** `display-buffer-at-bottom' chooses or creates a window at the
244bottom of the selected frame.
245
246**** `display-buffer-no-window' to not display the buffer in a window.
247
248*** New display action alist entry `allow-no-window' to indicate the
249caller of `display-buffer' is ready to handle the case of not displaying
250the buffer in a window.
251
252*** `display-buffer-in-previous-window' is now a member of
253`display-buffer-fallback-action'.
254
255** Lisp evaluation
256
257*** `eval-defun' on an already defined defcustom calls the :set function,
258if there is one.
259
260*** The commands `eval-expression' (`M-:'), `eval-last-sexp' (`C-x C-e'),
261and `eval-print-last-sexp' (`C-j' in Lisp Interaction mode) can take a
262zero prefix argument. This disables truncation of lists in the output,
263equivalent to setting `(eval-expression-)print-length' and
264`(eval-expression-)print-level' to nil. Additionally, it causes integers
265to be printed in other formats (octal, hexadecimal, and character).
266
267*** New hook `eval-expression-minibuffer-setup-hook' run by
268`eval-expression' on entering the minibuffer.
269
270** `cache-long-line-scans' is now non-nil, and renamed to `cache-long-scans',
271because it affects caching of paragraph scanning results as well.
272There is no reason to set this to nil except for debugging purposes.
273
274** `emacs-bzr-version' has been renamed to `emacs-repository-version',
275and works for git too, if you fetch the repository notes.
276
277** The default value of `comment-use-global-state' is now t,
278and this variable has been marked obsolete.
279
280** `write-region-inhibit-fsync' now defaults to t in batch mode.
281
282** The option `set-mark-default-inactive' has been deleted.
283This unfinished feature was introduced by accident in Emacs 23.1;
284simply disabling Transient Mark mode does the same thing.
285
286
287* Editing Changes in Emacs 24.4
288
289** Indentation
290
291*** `electric-indent-mode' is now enabled by default.
292Typing RET reindents the current line and indents the new line.
293`C-j' inserts a newline but does not indent. In some programming modes,
294additional characters are electric (eg `{').
295
296*** New buffer-local `electric-indent-local-mode'.
297
298*** The behavior of `C-x TAB' (`indent-rigidly') has changed.
299When invoked without a prefix argument, it now activates a transient
300mode in which typing <left>, <right>, <S-left>, and <S-right> adjusts
301the text indentation in the region. Typing any other key resumes
302normal editing behavior.
303
304*** `tab-stop-list' is now implicitly extended to infinity by repeating
305the last step. Its default value is changed to nil, which means a tab
306stop every `tab-width' columns.
307
308** Uniquify is enabled by default, with `post-forward-angle-brackets' style.
309In other words, if you visit two files that have the same base name,
310then rather than creating buffers basename and basename<2>,
311Emacs uses basename<dirA> and basename<dirB>. To change this,
312customize `uniquify-buffer-name-style'. Set it to nil for the old behavior.
313
314** New command `C-x SPC' (`rectangle-mark-mode') makes a rectangular region.
315Most commands are still unaware of it, but kill/yank do work on the rectangle.
316
317** New option `visual-order-cursor-movement'.
318If this is non-nil, cursor motion with arrow keys will follow the
319visual order of characters on the screen: <left> always moves to the
320left, <right> always moves to the right, disregarding the surrounding
321bidirectional context.
322
323** New command `delete-duplicate-lines'.
324This searches the region for identical lines, and removes all but one
325copy of each repeated line. The lines need not be sorted.
326
327** New command `cycle-spacing' acts like a smarter `just-one-space'.
328When called in succession, it cycles between spacing conventions:
329one space, no spaces, original spacing.
330
331** `blink-matching-paren' now only highlights the matching open-paren
332by default, instead of moving the cursor. Set this variable to `jump' to
333restore the old behavior.
334
335** The new function `fill-single-char-nobreak-p' can stop fill from breaking
336a line after a one-letter word, which is an error in some typographical
337conventions. To use it, add it to the `fill-nobreak-predicate' hook.
338
339** Registers
340
341*** All interactive commands that read a register (`copy-to-register', etc.)
342now display a temporary window after `register-preview-delay' seconds
343that summarizes existing registers. To disable this, set that option to nil.
344Interactive commands that read registers and want to make use of this
345should use `register-read-with-preview' to read register names.
346
347*** New command `frameset-to-register' bound to `C-x r f', replacing
348`frame-configuration-to-register'. It offers similar functionality,
349plus enhancements like the ability to restore deleted frames.
350(`frame-configuration-to-register' still exists, but no longer has a
351key binding.)
352
353*** New command `C-x C-k x' (`kmacro-to-register') stores keyboard
354macros in registers.
355
356
357* Changes in Specialized Modes and Packages in Emacs 24.4
358
359** Backtrace and debugger
360
361*** New Lisp debugger command `v' (`debugger-toggle-locals') toggles the
362display of local variables of the current stack frame.
363
364*** The Lisp debugger's `e' command (`debugger-eval-expression') now includes
365the lexical environment when evaluating the code in the context at point
366(and so allows you to access lexical variables).
367
368*** New minor mode `jit-lock-debug-mode' helps you debug code run via JIT Lock.
369
370** Battery information can now be retrieved from BSD's `apm' utility.
371
372** In the Buffer Menu, `M-s a C-o' shows matches for a regexp in marked buffers.
373
374** Calc
375
376*** Calc by default now uses the Gregorian calendar for all dates, and
377uses January 1, 1 AD as its day number 1. Previously Calc used the
378Julian calendar for dates before September 14, 1752, and it used
379December 31, 1 BC as its day number 1; the new scheme is more
380consistent with Calendar's calendrical system and day numbering.
381
382*** The new option `calc-gregorian-switch' lets you configure if
383(and when) Calc switches from the Julian to the Gregorian calendar.
384
385*** Support for ISO 8601 dates.
386
387** Calendar and Diary
388
389*** New faces `calendar-weekday-header', `calendar-weekend-header',
390and `calendar-month-header'.
391
392*** New option `calendar-day-header-array'.
393
394*** New variable `diary-from-outlook-function', used by the command
395`diary-from-outlook'.
396
397*** The variable `calendar-font-lock-keywords' is obsolete.
398
399** CEDET
400
401*** EDE
402
403**** The cpp-root project now supports executing a compile command.
404It can be set through the new :compile-command slot or the
405buffer-local variable `compile-command'.
406
407**** Better selection of include directories for the 'linux' project.
408Include directories now support out-of-tree build directories and
409target architecture auto-detection.
410
411*** Semantic
412
413**** Improved detection of used namespaces in current scope in C++.
414
415**** Parsing of default values for variables and function arguments in C/C++.
416They are also displayed by the summarize feature in the mode line.
417
418**** Improved parsing of function pointers in C/C++.
419This also includes parsing of function pointers as function arguments.
420
421**** Parsing of C/C++ preprocessor macros that open new scope.
422For example, this enables parsing of macros that open new namespaces.
423
424**** Support for 'this' pointer in inline member functions in C++.
425
426** CFEngine mode
427
428*** Support for completion, ElDoc, and Flycheck has been added.
429
430*** The current CFEngine syntax is parsed from "cf-promises -s json".
431There is a fallback syntax available if you don't have cf-promises or
432if your version doesn't support that option. See option `cfengine-cf-promises'.
433
434** cl-lib
435
436*** New macro `cl-tagbody'.
437This executes statements while allowing for control transfer to labels.
438
439*** letf is now just an alias for cl-letf.
440
441** CUA mode
442
443*** CUA mode now uses `delete-selection-mode' and `shift-select-mode'.
444Hence, you can now enable it independently from those modes, and from
445`transient-mark-mode'.
446
447*** `cua-highlight-region-shift-only' is now obsolete.
448You can disable `transient-mark-mode' to get the same result.
449
450*** CUA's rectangles can now be used without CUA by calling the command
451`cua-rectangle-mark-mode'.
452
453** Delete Selection mode can now be used without Transient Mark mode.
454
455** Desktop
456
457*** `desktop-save-mode' by default now auto-saves an existing desktop file
458after `desktop-auto-save-timeout'. To disable this, customize that option
459to nil (or zero).
460
461*** Desktop now saves and restores the frame/window configuration.
462To disable this, set `desktop-restore-frames' to nil.
463See also related options `desktop-restore-reuses-frames',
464`desktop-restore-in-current-display', and `desktop-restore-forces-onscreen'.
465
466** New Dired minor mode `dired-hide-details-mode' toggles whether details,
467such as file ownership or permissions, are visible in Dired buffers.
468See the new options `dired-hide-details-hide-symlink-targets' and
469`dired-hide-details-hide-information-lines' for customizing what to hide.
470
471** You can enable ElDoc inside the `eval-expression' minibuffer with:
472 (add-hook 'eval-expression-minibuffer-setup-hook 'eldoc-mode)
473The results display in the mode line.
474
475** Electric Pair mode
476
477*** New option `electric-pair-preserve-balance', enabled by default.
478If non-nil, pairing/skipping only kicks in when that help the balance
479of parentheses and quotes; i.e., the buffer should end up at least as
480balanced as before.
481
482You can further control this behavior by adjusting the predicates
483stored in `electric-pair-inhibit-predicate' and `electric-pair-skip-self'.
484
485*** New option `electric-pair-delete-adjacent-pairs', enabled by default.
486In `electric-pair-mode', the commands `backward-delete-char' and
487`backward-delete-char-untabify' are now bound to electric variants
488that delete the closer when invoked between adjacent pairs.
489
490*** New option `electric-pair-open-newline-between-pairs', enabled by default.
491In `electric-pair-mode', inserting a newline between adjacent pairs
492opens an extra newline after point, which is indented if
493`electric-indent-mode' is also set.
494
495*** New option `electric-pair-skip-whitespace', enabled by default.
496This controls if skipping over closing delimiters should jump over any
497whitespace slack. Setting it to `chomp' makes it delete this
498whitespace. See also the variable `electric-pair-skip-whitespace-chars'.
499
500*** New variables control the pairing in strings and comments.
501You can customize `electric-pair-text-pairs' and
502`electric-pair-text-syntax-table' to tweak pairing behavior inside
503strings and comments.
504
505** New EPA option `epa-mail-aliases'.
506You can set this to a list of email address aliases that `epa-mail-encrypt'
507should use to find keys.
508
509** New ERC option `erc-accidental-paste-threshold-seconds'.
510If set to a number, this can be used to avoid accidentally pasting large
511amounts of data into the ERC input.
512
513** New ERT macro `skip-unless' allows skipping ERT tests.
514
515** Eshell
516
517*** `eshell' now supports visual subcommands and options.
518Eshell has been able to handle "visual" commands (interactive,
519non-line oriented commands such as top that require display
520capabilities not provided by eshell) by running them in an Emacs
521terminal emulator. See `eshell-visual-commands'.
522
523This feature has been extended to subcommands and options that make a
524usually line-oriented command a visual command. Typical examples are
525"git log" and "git <command> --help", which display their output in a
526pager by default. See `eshell-visual-subcommands' and `eshell-visual-options'.
527
528*** New Eshell-Tramp module.
529External su and sudo commands are now the default; the internal,
530Tramp-using variants can still be used by enabling the eshell-tramp module.
531
532** New F90 mode option `f90-smart-end-names'.
533
534** New option `gnutls-verify-error', if non-nil, means that Emacs
535should reject SSL/TLS certificates that GnuTLS determines as invalid.
536(This option defaults to nil at present, but this is expected to change
537in a future release.)
538
539** Hi-Lock
540
541*** New global command `M-s h .' (`highlight-symbol-at-point') highlights
542the symbol near point.
543
544*** New option `hi-lock-auto-select-face'. When non-nil, hi-lock commands
545will cycle through faces in `hi-lock-face-defaults' without prompting.
546
547** Icomplete is now more similar to Ido.
548
549*** Icomplete by default now applies to all forms of minibuffer completion.
550The variable `icomplete-with-completion-tables' (now a user option)
551controls this. To restore the old behavior, set it back to
552'(internal-complete-buffer).
553
554*** You can navigate through and select completions using the keys
555from `icomplete-minibuffer-map'.
556
557*** The string that separates potential completions is now a customizable
558option (`icomplete-separator'). The default is " | " rather than ",".
559
560*** New face `icomplete-first-match'; and new options
561`icomplete-hide-common-prefix' and `icomplete-show-matches-on-no-input'.
562
563*** The option `icomplete-show-key-bindings' has been removed.
564
565** Ido
566
567*** An Ido user manual is now included.
568
569*** The option `ido-use-virtual-buffers' can now take the value `auto'.
570This means to use virtual buffers if the current ido input does not match
571an existing buffer.
572
573*** The variable `ido-decorations' can optionally have two new elements,
574which are the brackets to use around the sole remaining completion.
575
576** Image mode
577
578*** New commands `n' (`image-next-file') and `p' (`image-previous-file')
579visit the next image file and the previous image file in the same
580directory, respectively.
581
582*** New commands to show specific frames of multi-frame images.
583`f' (`image-next-frame') and `b' (`image-previous-frame') visit the
584next or previous frame. `F' (`image-goto-frame') shows a specific frame.
585
586*** New commands to speed up, slow down, or reverse animation.
587`a +' (`image-increase-speed') and `a -' (`image-decrease-speed') to
588speed up and slow down the animation. `a r' (`image-reverse-speed')
589to reverse it and `a 0' (`image-reset-speed') to reset it.
590
591*** The command `image-mode-fit-frame' deletes other windows.
592When toggling, it restores the frame's previous window configuration.
593It also has an optional frame argument, which can be used by Lisp
594callers to fit the image to a frame other than the selected frame.
595
596** New Imenu option `imenu-generic-skip-comments-and-strings'.
597
598** Info
599
600*** New Info face `info-index-match', used to highlight matches in index
601entries displayed by `Info-index-next', `Info-virtual-index' and
602`info-apropos'.
603
604*** The Info-edit command is obsolete. Editing Info nodes by hand
605has not been relevant for some time.
606
607** JS Mode
608
609*** New option `js-switch-indent-offset'.
610
611*** Better indentation of multiple-variable declarations.
612If a declaration spans several lines, variables on the following lines
613are lined up to the first one.
614
615*** Recognition and better indentation of continuations in array comprehensions.
616
617** MH-E has been updated to version 8.6 - see separate MH-E-NEWS file.
618
619** Octave mode
620
621*** Font locking for Texinfo comments and new keywords.
622
623*** Completion in Octave file buffers.
624
625*** ElDoc support.
626
627*** Jump to definition.
628
629*** Documentation lookup/search.
630
631** OPascal mode is the new name for Delphi mode
632
633*** All delphi-* variables and functions have been renamed to opascal-*.
634Obsolete aliases exist for those likely to have been used externally.
635
636*** The option `delphi-newline-always-indents' has been removed.
637Use `electric-indent-mode' instead.
638
639*** The TAB key runs the standard `indent-for-tab-command', not `delphi-tab'.
640
641** Package
642
643*** The package library now supports digital signing of packages.
644Maintainers of package archives should consider signing their packages
645to enhance security.
646
647**** If the user option `package-check-signature' is non-nil,
648Emacs tries to check package signatures at install time.
649The value `allow-unsigned' allows installation of unsigned packages.
650
651**** The user option `package-unsigned-archives' lists archives where
652Emacs will not try to check signatures.
653
654*** New option `package-pinned-packages'. This is useful if you have multiple
655archives enabled, with more than one offering a given package that you want.
656
657*** In the `list-packages' buffer, you can use `f' (`package-menu-filter')
658to filter the list of packages by a keyword.
659
660*** In the `describe-package' buffer, there are now buttons listing the
661keywords related to the package. Click on a button to see other packages
662related to that keyword.
663
664*** The format of `archive-contents' files, generated by package
665repositories, has changed to allow a new (fifth) element in the data
666vectors, containing an associative list with extra properties.
667(For example, `describe-package' uses the `:url' extra property to
668display a "Homepage" header.)
669
670** In Prolog mode, `prolog-use-smie' has been removed,
671along with the non-SMIE indentation code.
672
673** Python mode
674
675*** Out of the box support for CPython, iPython and readline based shells.
676**** `python-shell-completion-module-string-code' is no longer used.
677
678*** Automatic shell prompt detection. New user options:
679**** `python-shell-interpreter-interactive-arg'.
680**** `python-shell-prompt-detect-enabled'.
681**** `python-shell-prompt-detect-failure-warning'.
682**** `python-shell-prompt-input-regexps'.
683**** `python-shell-prompt-output-regexps'.
684
685*** Python shell support for remote hosts via tramp.
686
687*** Correct display of line numbers for code sent to the Python shell.
688
689** Remember
690
691*** The new command `remember-notes' creates a buffer that is saved on exit.
692You can use it as a more permanent *scratch* buffer.
693
694*** Remember can now store notes in separate files.
695To use this, add `remember-store-in-files' to the `remember-handler-functions'
696option. The files are saved in `remember-data-directory' using
697names specified by `remember-directory-file-name-format'.
698
699** Rmail
700
701*** Customize `rmail-mbox-format' to influence some minor aspects of
702how Rmail displays non-MIME messages.
703
704*** The `unrmail' command now converts from BABYL to mboxrd format,
705rather than mboxo. Customize `unrmail-mbox-format' to change this.
706
707** Ruby mode
708
709*** Improved syntax highlighting and indentation.
710
711*** New `electric-indent-mode' integration.
712
713*** New option `ruby-encoding-magic-comment-style'.
714
715*** New option `ruby-custom-encoding-magic-comment-template'.
716
717*** New option `ruby-align-to-stmt-keywords'.
718
719*** New option `ruby-align-chained-calls'.
720
721*** More Ruby file types have been added to `auto-mode-alist'.
722
723** Search and Replace
724
725*** New global command `M-s .' (`isearch-forward-symbol-at-point')
726starts a symbol (identifier) incremental search forward with the
727symbol found near point added to the search string initially.
728
729*** `C-x 8 RET' in Isearch mode reads a character by its Unicode name
730and adds it to the search string.
731
732*** `M-s i' in Isearch mode toggles whether search matches invisible text.
733
734*** `query-replace' skips invisible text when `search-invisible' is nil,
735and opens overlays with hidden text when `search-invisible' is `open'.
736
737*** A negative prefix argument of replacement commands replaces backward.
738`M-- M-%' replaces a string backward, `M-- C-M-%' replaces a regexp
739backward, `M-s w words M-- M-%' replaces a sequence of words backward.
740
741*** By default, prefix arguments do not now terminate Isearch mode.
742Set `isearch-allow-prefix' to nil to restore the old behavior.
743
744*** More Isearch commands accept prefix arguments, namely
745`isearch-printing-char', `isearch-quote-char', `isearch-yank-word',
746`isearch-yank-line'.
747
748*** Word search now matches whitespace at the beginning/end
749of the search string if it contains leading/trailing whitespace.
750In an incremental word search or when using a non-nil LAX argument
751of `word-search-regexp', the lax matching can also match part of
752the first word (in addition to the lax matching of the last word).
753The same rules are now applied to the symbol search, with the difference
754that it matches symbols, and non-symbol characters between symbols.
755
756** New SES command `ses-rename-cell' allows assignment of names to SES cells.
757
758** The shell.el option `explicit-bash-args' includes --noediting by default.
759All non-ancient Bash versions support this option.
760
761** Shell Script mode
762
763*** The SMIE indentation engine is now used by default - see `sh-use-smie'.
764
765*** `sh-mode' now has its own setting for `add-log-current-defun-function'.
766
767** SMIE
768
769*** You can customize the SMIE indentation of a mode via `smie-config'.
770The command `smie-config-guess' can help you derive the appropriate
771indentation settings, if you provide it with an indented sample file.
772Use `smie-config-save' to save the result.
773
774*** You can customize the SMIE indentation of a file by adding an entry to
775the file's local variables of the form: `eval: (smie-config-local '(RULES))'.
776
777*** New commands `smie-config-show-indent' and `smie-config-set-indent'.
778
779** SQL mode
780
781*** Improved login monitoring and appropriate response to login failures.
782New variable `sql-login-delay' defines maximum wait time for a connection.
783
784*** Oracle support.
785SQL*Plus script placeholders are properly highlighted and identified
786in `sql-placeholders-filter'. When starting SQL*Plus, `sql-oracle-options'
787are passed before the logon parameter, as required. The default now
788includes `-L', to limit the number of logon attempts per invocation.
789
790** New Term mode option `term-suppress-hard-newline'.
791
792** Todo mode has been rewritten and enhanced.
793The Todo mode user manual describes all commands and most user
794options. To support some of these features, a new file format is
795used, which is incompatible with the old format; however, you can
796convert old todo and done item files to the new format on initializing
797the first new todo file, or at any later time with the provided
798conversion command. The previous version of todo-mode.el has been
799renamed to otodo-mode.el and is now obsolete. New features include:
800
801*** Support for multiple todo files and archive files of done items.
802
803*** Renaming, reordering, moving, merging, and deleting categories.
804
805*** Sortable tabular summaries of categories and the item types they contain.
806
807*** Cross-category lists of items filtered by specific criteria.
808
809*** More fine-grained interaction with the Emacs diary, by being able to
810decide for each todo item whether it appears in the Fancy Diary display.
811
812*** Highly flexible new item insertion and item editing.
813
814*** Moving items between categories, storing done items in their category
815or in archive files, undoing or unarchiving done items.
816
817*** Reprioritizing items by inputting a numerical priority.
818
819*** Extensive customizability of operation and display, including many faces.
820
821** Trace
822
823*** `trace-function' and `trace-function-background' no longer prompt for
824the output buffer. Unless you use a prefix argument, they output to
825`trace-buffer'.
826
827*** With a prefix argument, `trace-function' and `trace-function-background'
828will prompt for a "context". This is a Lisp expression, whose value at the
829time the function is entered/exited is printed along with the function's
830name and arguments.
831
832** Tramp
833
834*** New connection method "adb", which allows to access Android
835devices by the Android Debug Bridge. The variable `tramp-adb-program'
836can be used to adapt the path of the "adb" program, if needed.
837
838*** Handlers for `file-acl' and `set-file-acl' for remote machines
839that support POSIX ACLs.
840
841*** Handlers for `file-notify-add-watch' and `file-notify-rm-watch'
842for remote machines that support filesystem notifications.
843
844*** The experimental url syntax for remote file names has been removed.
845
846*** The connection methods "plink1", "ssh1", "ssh2", "scp1", "scp2",
847"scpc" and "rsyncc" are discontinued. The ssh option
848"ControlMaster=auto" is set automatically in all ssh-based methods,
849when possible. See `tramp-use-ssh-controlmaster-options'.
850
851** New URL command `url-cookie-list' displays the current cookies,
852and allows you to interactively remove cookies.
853
854** VC and related modes
855
856*** In VC directory mode, `D' displays diffs between VC-controlled
857whole tree revisions.
858
859*** In VC directory mode, `L' lists the change log for the current VC
860controlled tree in a window.
861
862*** In VC directory mode, `I' shows a log of changes that will be
863received with a pull operation.
864
865*** `C-x v G' (globally) and `G' (in VC directory mode) ignores a file
866under current version control system. When called with a prefix
867argument, you can remove a file from the ignored file list.
868
869** VHDL mode
870
871*** New options: `vhdl-actual-generic-name', `vhdl-beautify-options'.
872
873*** New commands: `vhdl-fix-statement-region', `vhdl-fix-statement-buffer'.
874
875** The Woman commands `woman-default-faces' and `woman-monochrome-faces'
876are obsolete. Customize the `woman-*' faces instead.
877
878** More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>.
879Affected files:
880~/.emacs.d/timelog replaces ~/.timelog
881~/.emacs.d/vip replaces ~/.vip
882~/.emacs.d/viper replaces ~/.viper
883~/.emacs.d/ido.last replaces ~/.ido.last
884~/.emacs.d/kkcrc replaces ~/.kkcrc
885~/.emacs.d/quickurls replaces ~/.quickurls
886~/.emacs.d/idlwave/ replaces ~/.idlwave/
887~/.emacs.d/bdfcache.el replaces ~/.bdfcache.el
888~/.emacs.d/places replaces ~/.emacs-places
889~/.emacs.d/shadows replaces ~/.shadows
890~/.emacs.d/shadow_todo replaces ~/.shadow_todo
891~/.emacs.d/strokes replaces ~/.strokes
892~/.emacs.d/notes replaces ~/.notes
893~/.emacs.d/type-break replaces ~/.type-break
894Also the following files used by the now obsolete otodo-mode.el:
895~/.emacs.d/todo-do replaces ~/.todo-do
896~/.emacs.d/todo-done replaces ~/.todo-done
897~/.emacs.d/todo-top replaces ~/.todo-top
898
899** Obsolete packages
900
901*** iswitchb.el; use icomplete-mode.
902
903*** longlines.el; use visual-line-mode.
904
905*** meese.el.
906
907*** sup-mouse.el.
908
909*** terminal.el; use term.el instead.
910
911*** the old version of todo-mode.el (renamed to otodo-mode.el).
912
913*** xesam.el (owing to the cancellation of the XESAM project).
914
915*** yow.el; use fortune.el or cookie1.el instead.
916
917
918* New Modes and Packages in Emacs 24.4
919
920** New package eww.el provides a built-in web browser.
921This requires Emacs to have been compiled with libxml2 support.
922
923** New package nadvice.el offers lighter-weight advice facilities.
924It is layered as:
925
926*** `add-function'/`remove-function', which can be used to add/remove code on
927any function-carrying place, such as process filters or `<foo>-function' hooks.
928
929*** `advice-add'/`advice-remove' to add/remove a piece of advice on a named
930function, much like `defadvice' does.
931
932** New package frameset.el provides a set of operations to save a frameset
933(the state of all or a subset of the existing frames and windows, somewhat
934similar to a frame configuration), both in-session and persistently, and
935restore it at some point in the future.
936
937** New package filenotify.el provides an interface for file system
938notifications. It requires that Emacs be compiled with one of the
939low-level libraries gfilenotify.c, inotify.c or w32notify.c.
940
941** New minor modes `prettify-symbols-mode' and `global-prettify-symbols-mode'
942display specified symbols as composed characters. E.g., in Emacs Lisp mode,
943this replaces the string "lambda" with the Greek lambda character.
944
945** New minor mode `superword-mode', which overrides the default word motion
946commands to treat "symbol_words" as a single word, similar to what
947`subword-mode' does.
948
949
950* Incompatible Lisp Changes in Emacs 24.4
951
952** The default file coding for Emacs Lisp files is now utf-8.
953(See `file-coding-system-alist'.) In most cases, this change is
954transparent, but files that contain unusual characters without
955specifying an explicit coding system may fail to load with obscure
956errors. You should either convert them to utf-8 or add an explicit
957`coding:' cookie.
958
959** Default process filters and sentinels are not nil any more.
960Instead they default to a function that does what the nil value used to do.
961
962** Overlay priority does not have to be nil or a non-negative integer.
963Overlay priority can be other kinds of Lisp objects. We didn't yet
964decide whether other types of values are stable enough, and therefore
965don't feel it's right to document them. For now, don't assume in your
966code that the values of overlay priority can only be either nil or an
967integer, always test them with an appropriate predicate to be one or
968the other. If you need to sort arbitrary overlays into priority
969order, `overlays-at' can now optionally do this.
970You should still only specify integer priorities on overlays you create.
971
972** The cars of the elements in `interpreter-mode-alist' are now
973treated as regexps rather than literal strings.
974
975** `overriding-terminal-local-map' no longer replaces the local keymaps.
976It used to disable the minor mode, major mode, and text-property keymaps,
977whereas now it simply has higher precedence.
978
979** `kill-region' has lost its `yank-handler' optional argument.
980
981** `(input-pending-p)' no longer runs other timers that are ready to run.
982The new optional CHECK-TIMERS parameter allows for the prior behavior.
983
984** `defvar' and `defcustom' in a let-binding affect the "external" default.
985
986** The syntax of ?» and ?« is now punctuation instead of matched parens.
987Some languages match those as »...«, and others as «...», so it is
988better for Emacs to stay neutral by default.
989
990** `read-event' does not always decode chars in ttys any more. As was the case
991in Emacs 22 and before, `read-event' (and `read-char') by default read raw
992bytes from the terminal. If you want to read decoded chars instead (as was
993always the case in Emacs-23, for example), pass a non-nil
994`inherit-input-method' argument.
995
996** In `symbol-function', nil and "unbound" are indistinguishable.
997`symbol-function' does not signal a `void-function' error any more.
998To determine if a symbol's function definition is void, use `fboundp'.
999
1000** `defadvice' does not honor the `freeze' flag and cannot advise
1001special-forms any more.
1002
1003** `dolist' no longer binds VAR while evaluating the RESULT form,
1004when lexical binding is enabled. Previously, VAR was bound to nil,
1005which often led to spurious unused-variable warnings.
1006
1007** The return value of `backup-buffer' has changed.
1008The second argument is no longer an SELinux context, instead it is an
1009alist of extended attributes as returned by the new function
1010`file-extended-attributes'. The attributes can be applied to another
1011file using `set-file-extended-attributes'.
1012
1013** By default `copy-file' no longer copies file permission bits to an
1014existing destination; and it sets the file permission bits of a newly
1015created destination to those of the source, masked by the default file
1016permissions. To copy the file permission bits, pass t as the
1017PRESERVE-PERMISSIONS argument of `copy-file'.
1018
1019** `visited-file-modtime' now returns -1 for nonexistent files.
1020Formerly it returned a list (-1 LOW USEC PSEC), but this was ambiguous
1021in the presence of files with negative time stamps.
1022
1023** Frame-local variables that affect redisplay do not work any more.
1024More specifically, redisplay does not bother to check for a frame-local
1025value when looking up variables.
1026
1027** In compiled Lisp files, the header no longer includes a timestamp.
1028
1029** The option `inhibit-local-menu-bar-menus' has been removed.
1030
1031
1032* Lisp Changes in Emacs 24.4
1033
1034** Change to the Emacs Lisp coding conventions: the package descriptor
1035and name of global variables, constants, and functions should be separated
1036by two hyphens if the symbol is not meant to be used by other packages.
1037
1038** The second argument of `eval' can now specify a lexical environment.
1039
1040** New macro `define-alternatives' can be used to define generic commands.
1041Generic commands are interactive functions whose implementation can be
1042selected among several alternatives, as a matter of user preference.
1043
1044** Numeric comparison functions =, <, >, <=, >= can now take many arguments.
1045
1046** New functions `special-form-p' and `macrop'.
1047
1048** New macro `with-eval-after-load'.
1049This is like the old `eval-after-load', but better behaved.
1050
1051** If you give a symbol a `defalias-fset-function' property, `defalias'
1052on that symbol will use the associated value as a function to call
1053in place of `fset'.
1054
1055** New variable `enable-dir-local-variables'.
1056Directory-local variables are ignored if this is nil. This may be
1057useful for modes that want to ignore directory-locals while still
1058respecting file-local variables.
1059
1060** `read-regexp' now uses the new variable `read-regexp-defaults-function'
1061as a function to call to provide default values.
1062
1063** New functions `group-gid' and `group-real-gid'.
1064
1065** New function `get-pos-property'.
1066
1067** New hook `pre-redisplay-function'.
1068
1069** `byte-compile-interactive-only-functions' is now obsolete.
1070To specify that a command should only be called interactively, give it
1071a non-nil `interactive-only' property.
1072
1073** New function `string-suffix-p'.
1074
1075** `split-string' now takes an optional argument TRIM.
1076The value, if non-nil, is a regexp that specifies what to trim from
1077the start and end of each substring.
1078
1079** Completion
1080
1081*** The separator used by `completing-read-multiple' is now a regexp.
1082The default `crm-separator' has been changed to allow surrounding spaces
1083around the comma.
1084
1085*** New function `completion-table-with-cache' is a wrapper for
1086`completion-table-dynamic' that caches the result of the last lookup.
1087
1088*** New function `completion-table-merge' to combine several
1089completion tables by merging their completions.
1090
1091*** The `common-substring' argument of `display-completion-list',
1092which has been documented as obsolete since Emacs 23.1, is now _really_
1093obsolete, and no longer advertised. Instead either call
1094`completion-hilit-commonality' to add the highlighting; or use
1095`completion-all-completions', which returns highlighted strings.
1096
1097** Encoding and decoding of text
1098
1099*** New coding-system `prefer-utf-8'.
1100This is like `undecided' but prefers UTF-8 on decoding if the text to
1101be decoded does not contain any invalid UTF-8 sequences. On encoding,
1102any non-ASCII characters are automatically encoded as UTF-8.
1103
1104*** New attributes of coding-systems whose type is `undecided'.
1105Two new attributes, `:inhibit-null-byte-detection' and
1106`:inhibit-iso-escape-detection', determine how to detect encoding of
1107text that includes null bytes and ISO-2022 escape sequences, respectively.
1108Each of these attributes can be either nil, zero, or t. If t, decoding
1109text ignores null bytes and ISO-2022 sequences, respectively. If nil,
1110null bytes cause text to be decoded with no-conversion, and ISO-2022
1111sequences cause Emacs to assume the text is encoded in one of the ISO-2022
1112encodings, such as iso-2022-7bit. If zero, Emacs consults the variables
1113`inhibit-null-byte-detection' and `inhibit-iso-escape-detection'.
1114The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer
1115UTF-8 encoding and decoding, whenever possible.
1116
1117These attributes are only meaningful for coding-systems of type `undecided'.
1118(The type of a coding-system is determined by its `:coding-type' attribute
1119and can be accessed by calling the `coding-system-type' function.)
1120
1121** Error-handling
1122
1123*** New function `define-error'.
1124
1125*** `with-demoted-errors' takes an additional argument `format'.
1126
1127*** Errors from timer functions are no longer silently discarded,
1128but are reported as messages. So you may see "Error running timer"
1129messages from code that was failing silently till now. Set
1130`debug-on-error' non-nil to get a real error and a backtrace.
1131
1132** Faces
1133
1134*** Face specs set via Custom themes now replace the `defface' spec
1135rather than inheriting from it. In other words, setting a face via a
1136theme now behaves like setting it via Customize: you only need to
1137specify the attributes that you want, you don't need to unset those
1138that you don't want.
1139
1140*** The function `face-spec-set' is now like `setq' for face specs.
1141Its third arg now accepts values specifying a face spec type (defface,
1142custom, or override spec), and the relevant spec is set accordingly.
1143
1144*** New face spec attribute :distant-foreground
1145specifies foreground to use if background color is near the foreground
1146color that would otherwise have been used.
1147
1148*** New function `add-face-text-property', which can be used to
1149conveniently prepend/append new face properties.
1150
1151*** New face characteristic (supports :underline (:style wave))
1152specifies whether or not the terminal can display a wavy line.
1153
1154** File-handling
1155
1156*** Support for filesystem notifications.
1157Emacs now supports notifications of filesystem changes, such as
1158creation, modification, and deletion of files. This requires the
1159`glib' API, or the 'inotify' API (on GNU/Linux systems only). On
1160MS-Windows systems, this is supported for Windows XP and newer.
1161
1162*** The 9th element returned by `file-attributes' is now unspecified.
1163Formerly, it was t if the file's gid would change if file were deleted
1164and recreated. This value has been inaccurate for years on many
1165platforms, and nobody seems to have noticed or cared.
1166
1167*** The 6th argument to `copy-file' has been renamed to
1168PRESERVE-PERMISSIONS as it now handles ACL entries and the traditional
1169Unix file permission bits as well as SELinux context.
1170
1171*** The function `file-ownership-preserved-p' now has an optional
1172argument GROUP which causes it check for file group too. This can be
1173used in place of the 9th element of `file-attributes'.
1174
1175*** The function `set-visited-file-modtime' now accepts a 0 or -1 argument,
1176with the same interpretation as the returned value of `visited-file-modtime'.
1177
1178** Image API
1179
1180*** `image-animated-p' is now `image-multi-frame-p'.
1181It returns non-nil for any image that contains multiple frames,
1182whether or not it specifies a frame delay.
1183
1184*** New variable `image-default-frame-delay' gives the frame delay for
1185animated images which do not specify a frame delay.
1186
1187*** New functions `image-current-frame' and `image-show-frame' for getting
1188and setting the current frame of a multi-frame image.
1189
1190** ImageMagick
1191
1192*** ImageMagick images now support the :max-width and :max-height keywords.
1193
1194*** When using `create-image' with image data, you can pass a :format
1195attribute (via the property-list argument) in order to help
1196ImageMagick detect the image type. The value should be a MIME
1197content-type that is found in the new variable `image-format-suffixes'.
1198
1199** Revert and Autorevert
1200
1201*** If Emacs is compiled with file notification support, it uses notifications
1202instead of checking file time stamps. To disable this, set the user option
1203`auto-revert-use-notify' to nil. Alternatively, you can specify a regular
1204expression matching directories to be excluded from file notifications via
1205`auto-revert-notify-exclude-dir-regexp'.
1206
1207*** The default values of `buffer-stale-function', `revert-buffer-function',
1208and `revert-buffer-insert-file-contents-function' are no longer nil.
1209Instead they default to functions that do what the nil value used to.
1210
1211*** `buffer-stale-function' is now used for buffers visiting files too.
1212
1213*** The new user option `auto-revert-remote-files' enables reversion
1214of remote files, if non-nil.
1215
1216** Terminal
1217
1218*** Functions to pop up menus and dialogs now work on all terminals,
1219including TTYs. This includes `x-popup-menu', `x-popup-dialog',
1220`message-box', `yes-or-no-p', etc.
1221
1222The function `display-popup-menus-p' will now return non-nil for a
1223display or frame whenever a mouse is supported on that display or frame.
1224
1225*** New hook `tty-setup-hook', run at the end of initializing a text terminal.
1226
1227*** The hook `term-setup-hook' is obsolete. It is entirely equivalent
1228to `emacs-startup-hook'. See also the new `tty-setup-hook'.
1229
1230** Minor internal changes to the details of lock files.
1231The lock for DIR/FILE is now _always_ DIR/.#FILE.
1232If DIR/.#FILE already exists and is not an Emacs lock file,
1233Emacs makes no attempt to lock DIR/FILE. (Previously, it fell back to
1234numbered lock files DIR/.#FILE.0...).
1235On file systems that do not support symbolic links, the lock is now a
1236regular file with contents being what would have been in the symlink.
1237
1238** New bool-vector set operation functions:
1239*** `bool-vector-exclusive-or'
1240*** `bool-vector-union'
1241*** `bool-vector-intersection'
1242*** `bool-vector-set-difference'
1243*** `bool-vector-not'
1244*** `bool-vector-subsetp'
1245*** `bool-vector-count-consecutive'
1246*** `bool-vector-count-population'
1247
1248** New library subr-x.el with miscellaneous small utility functions:
1249*** `hash-table-keys'
1250*** `hash-table-values'
1251*** `string-blank-p'
1252*** `string-empty-p'
1253*** `string-join'
1254*** `string-reverse'
1255*** `string-trim-left'
1256*** `string-trim-right'
1257*** `string-trim'
1258*** `string-remove-prefix'
1259*** `string-remove-suffix'
1260
1261** The `time-to-seconds' alias to `float-time' is no longer marked obsolete.
1262
1263** The spelling of the rx.el category `chinese-two-byte' has been
1264corrected (the first 'e' was missing).
1265
1266** EIEIO namespace cleanup, obsolete-aliasing functions to use `eieio-' prefix:
1267*** object-name -> eieio-object-name
1268*** object-class -> eieio-object-class
1269*** object-class-fast -> eieio--object-class
1270*** object-class-name -> eieio-object-class-name
1271*** object-name-string -> eieio-object-name-string
1272*** object-num-slots -> eieio--object-num-slots
1273*** object-set-name-string -> eieio-object-set-name-string
1274*** class-of -> eieio-object-class
1275*** class-name -> eieio-class-name
1276*** class-parent -> eieio-class-parent
1277*** class-parents -> eieio-class-parents
1278*** class-parents-fast -> eieio-class-parents-fast
1279*** class-children -> eieio-class-children
1280*** class-num-slots -> eieio--class-num-slots
1281*** class-precedence-list -> eieio-class-precedence-list
1282*** class-direct-subclasses -> eieio-class-children
1283*** class-direct-superclasses -> eieio-class-parents
1284
1285** Obsoleted functions
1286*** `log10'
1287*** `dont-compile'
1288*** `lisp-complete-symbol'
1289*** `field-complete'
1290*** `minibuffer-completion-contents'
1291*** `isearch-nonincremental-exit-minibuffer'
1292*** `isearch-filter-visible'
1293*** `generic-make-keywords-list'
1294*** `get-upcase-table' (use `case-table-get-table' instead).
1295
1296** `with-wrapper-hook' is obsoleted by `add-function'.
1297The few hooks that used with-wrapper-hook are replaced as follows:
1298*** `abbrev-expand-function' obsoletes `abbrev-expand-functions'.
1299*** `completion-in-region-function' obsoletes `completion-in-region-functions'.
1300*** `filter-buffer-substring-function' obsoletes `filter-buffer-substring-functions'.
1301
1302
1303* Changes in Emacs 24.4 on Non-Free Operating Systems
1304
1305** New Core Text based font backend for Mac OS X 10.5 and newer.
1306To use the old font backend, use the following on the command line:
1307 % defaults write org.gnu.Emacs FontBackend ns
1308GNUstep and Mac OS X 10.4 use the old font backend.
1309
1310** Improved fullscreen support on Mac OS X 10.7 and newer, where the
1311default fullscreen method is now "native" fullscreen. To use the
1312old style fullscreen, customize `ns-use-native-fullscreen' to nil.
1313
1314** On Mac OS X 10.7 and newer, Emacs can use sRGB colorspace, and does so
1315by default. Customize `ns-use-srgb-colorspace' to go back to the old method.
1316Note that this does not apply to images.
1317
1318** The procedure for building Emacs on MS-Windows has changed.
1319It is now built by running the same configure script as on all other
1320platforms. This requires the MSYS environment and MinGW development
1321tools. See the updated instructions in nt/INSTALL for details.
1322
1323Using the Posix configure script and Makefiles also means a change in
1324the directory structure of the Emacs installation on Windows. It is
1325now the same as on GNU and Unix systems. In particular, the auxiliary
1326programs, such as cmdproxy.exe and hexl.exe, are in
1327libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs
1328version), version-independent site-lisp is in share/emacs/site-lisp,
1329version-specific Lisp files are in share/emacs/VERSION/lisp and in
1330share/emacs/VERSION/site-lisp, Info docs are in share/info, and data
1331files are in share/emacs/VERSION/etc. (Emacs knows about all these
1332directories and will find the files in there automatically; there's no
1333need to set any variables due to this change.)
1334
1335** Emacs on Windows 2000 and later can now access files and directories
1336whose names cannot be encoded in the current system codepage.
1337
1338The new variable `w32-unicode-filenames' controls this feature: if it
1339is t, Emacs uses Unicode APIs to pass file names to system calls,
1340which lifts the limitation of file names to the current locale.
1341
1342** Lock files now work on MS-Windows.
1343This helps to prevent losing your edits if the same file is being
1344edited in another Emacs session or by another user. See the node
1345"Interlocking" in the Emacs User Manual for the details. To disable
1346file locking, customize `create-lockfiles' to nil.
1347
1348** The "generate a backtrace on fatal error" feature now works on MS-Windows.
1349The backtrace is written to the 'emacs_backtrace.txt' file in the
1350directory where Emacs was running.
1351
1352** The `network-interface-list' and `network-interface-info' functions
1353are now available on MS-Windows.
1354
1355** The variable `buffer-file-type' is no longer supported.
1356Setting it has no effect, and %t in the mode-line format is ignored.
1357Likewise, `file-name-buffer-file-type-alist' is now obsolete, and
1358modifying it has no effect.
1359
1360
1361* Installation Changes in Emacs 24.3
1362
1363** The default X toolkit is now Gtk+ version 3.
1364If you don't pass `--with-x-toolkit' to configure, or if you use
1365`--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try
1366to build with Gtk+ version 3, and if that fails, try Gtk+ version 2.
1367You can explicitly require a specific version by passing
1368`--with-x-toolkit=gtk2' or `--with-x-toolkit=gtk3' to configure.
1369
1370** New configure option `--enable-link-time-optimization', to utilize
1371an appropriate feature provided by GCC since version 4.5.0.
1372
1373** New configure option `--without-all' to disable most of the optional
1374features (image support, etc.) that are normally enabled by default.
1375
1376** New configure option `--enable-gcc-warnings' (for developing/debugging
1377Emacs). If building with GCC, this enables compile-time checks that
1378warn/give errors about possibly-questionable C code. On a recent GNU
1379system there should be no warnings; on older and on non-GNU systems
1380the results may be useful to developers.
1381
1382** The configure option `--enable-use-lisp-union-type' has been
1383renamed to `--enable-check-lisp-object-type', as the resulting
1384Lisp_Object type no longer uses a union to implement the compile time
1385check that this option enables.
1386
1387** The configure option `--disable-maintainer-mode' has been removed,
1388as it was confusingly-named and rarely useful.
1389
1390** The configure options `--program-prefix', `--program-suffix', and
1391`--program-transform-name' apply to more than just the installed
1392binaries. Now they also affect the man pages, icons, and the
1393etc/emacs.desktop file; but not the info pages, since this would break
1394links between the various manuals.
1395
1396** You can use `NO_BIN_LINK=t make install' to prevent the installation
1397overwriting "emacs" in the installation bin/ directory with a link
1398to "emacs-VERSION".
1399
1400** Emacs uses libtinfo in preference to libncurses, if available.
1401
1402** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and
1403/usr/pkg/lib to the linker search path. You must add them yourself if
1404you want them.
1405
1406** The standalone scripts `rcs-checkin' and `vcdiff' have been removed
1407(from the bin and libexec directories, respectively). The former is
1408no longer relevant, the latter is replaced by lisp (in vc-sccs.el).
1409
1410
1411* Startup Changes in Emacs 24.3
1412
1413** Emacs no longer searches for `leim-list.el' files beneath the standard
1414lisp/ directory. There should not be any there anyway. If you have
1415been adding them there, put them somewhere else; e.g., site-lisp.
1416
1417** The `--no-site-lisp' command line option now works for Nextstep builds.
1418
1419
1420* Changes in Emacs 24.3
1421
1422** Help
1423
1424*** `C-h f' (`describe-function') can now perform autoloading.
1425When this command is called for an autoloaded function whose docstring
1426contains a key substitution construct, that function's library is
1427automatically loaded, so that the documentation can be shown
1428correctly. To disable this, set `help-enable-auto-load' to nil.
1429
1430*** `C-h f' now reports previously-autoloaded functions as "autoloaded",
1431even after their associated libraries have been loaded (and the
1432autoloads have been redefined as functions).
1433
1434** ImageMagick
1435
1436*** Images displayed via ImageMagick now support transparency and the
1437:background image specification property.
1438
1439*** When available, ImageMagick support is automatically enabled.
1440It is no longer necessary to call `imagemagick-register-types'
1441explicitly to install ImageMagick image types; that function is called
1442automatically at startup, or when customizing an imagemagick- option.
1443
1444*** Setting `imagemagick-types-inhibit' to t now disables the use of
1445ImageMagick to view images. (You must call `imagemagick-register-types'
1446afterwards if you do not use customize to change this.)
1447
1448*** The new variable `imagemagick-enabled-types' also affects which
1449ImageMagick types are treated as images. The function
1450`imagemagick-filter-types' returns the list of types that will be
1451treated as images.
1452
1453** Minibuffer
1454
1455*** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
1456next and previous path separator, respectively.
1457
1458*** `minibuffer-electric-default-mode' can shorten "(default ...)" to "[...]"
1459in minibuffer prompts. Just set `minibuffer-eldef-shorten-default'
1460non-nil before enabling the mode.
1461
1462** Mode line
1463
1464*** New option `mode-line-default-help-echo' specifies the help text
1465(shown in a tooltip or in the echo area) for any part of the mode line
1466that does not have its own specialized help text.
1467
1468*** You can now click mouse-3 in the coding system indicator to invoke
1469`set-buffer-file-coding-system'.
1470
1471** Server and client
1472
1473*** emacsclient now obeys string values for `initial-buffer-choice',
1474if it is told to open a new frame without specifying any file to visit
1475or expression to evaluate.
1476
1477*** New option `server-auth-key' specifies a shared server key.
1478
1479** Emacs now generates backtraces on fatal errors.
1480On encountering a fatal error, Emacs now outputs a textual description
1481of the fatal signal, and a short backtrace on platforms like glibc
1482that support backtraces.
1483
1484** `C-x C-q' is now bound to the new minor mode `read-only-mode'.
1485This minor mode replaces `toggle-read-only', which is now obsolete.
1486
1487** Most `y-or-n' prompts now allow you to scroll the selected window.
1488Typing `C-v' or `M-v' at a y-or-n prompt scrolls forward or backward
1489respectively, without exiting from the prompt.
1490
1491** In the Package Menu, newly-available packages are listed as "new",
1492and sorted above the other "available" packages by default.
1493
1494** If your Emacs was built from a repository checkout, the new variable
1495`emacs-bzr-version' contains information about the bzr revision used.
1496
1497** New option `create-lockfiles' specifies usage of lockfiles.
1498It defaults to t. Changing it to nil inhibits the creation of lock
1499files (use this with caution).
1500
1501** New option `enable-remote-dir-locals', if non-nil, allows directory-local
1502variables on remote hosts.
1503
1504** The entry for PCL-CVS has been removed from the Tools menu.
1505The PCL-CVS commands are still available via the keyboard.
1506
1507** Using "unibyte: t" in Lisp source files is obsolete.
1508Use "coding: raw-text" instead.
1509
1510** In the buffer made by `M-x report-emacs-bug', the `C-c m' binding
1511has been changed to `C-c M-i' (`report-emacs-bug-insert-to-mailer').
1512The previous binding, introduced in Emacs 24.1, was a mistake, because
1513`C-c LETTER' bindings are reserved for user customizations.
1514
1515** Internationalization
1516
1517*** New language environment: Persian.
1518
1519*** New input method `vietnamese-vni'.
1520
1521** Nextstep (GNUstep / Mac OS X) port
1522
1523*** Support for fullscreen and the frame parameter fullscreen.
1524
1525*** A file dialog is used for open/save operations initiated from the
1526menu/toolbar.
1527
1528
1529* Editing Changes in Emacs 24.3
1530
1531** Search and Replace
1532
1533*** Non-regexp Isearch now performs "lax" space matching.
1534Each sequence of spaces in the supplied search string may match any
1535sequence of one or more whitespace characters, as specified by the
1536variable `search-whitespace-regexp'. (This variable is also used by a
1537similar existing feature for regexp Isearch.)
1538
1539*** New Isearch command `M-s SPC' toggles lax space matching.
1540This applies to both ordinary and regexp Isearch.
1541
1542*** New option `replace-lax-whitespace'.
1543If non-nil, `query-replace' uses flexible whitespace matching too.
1544The default is nil.
1545
1546*** Global `M-s _' starts a symbol (identifier) incremental search,
1547and `M-s _' in Isearch toggles symbol search mode.
1548`M-s c' in Isearch toggles search case-sensitivity.
1549
1550** Navigation commands
1551
1552*** New binding `M-g c' for `goto-char'.
1553
1554*** New binding `M-g TAB' for `move-to-column'.
1555
1556*** `M-g TAB' (`move-to-column') prompts for a column number if called
1557interactively with no prefix arg. Previously, it moved to column 1.
1558
1559** New option `yank-handled-properties' allows processing of text
1560properties on yanked text, in ways that are more general than just
1561removing them (as is done by `yank-excluded-properties').
1562
1563** New option `delete-trailing-lines' specifies whether
1564M-x delete-trailing-whitespace should delete trailing lines at the end
1565of the buffer. It defaults to t.
1566
1567** `C-u M-=' now counts lines/words/characters in the entire buffer.
1568
1569** `C-x 8 RET' is now bound to `insert-char', which is now a command.
1570`ucs-insert' is now an obsolete alias for `insert-char'.
1571
1572** The `z' key no longer has a binding in most special modes.
1573It used to be bound to `kill-this-buffer', but `z' is too easy to
1574accidentally type.
1575
1576** New command `C-x r M-w' (`copy-rectangle-as-kill').
1577It copies the region-rectangle as the last rectangle kill.
1578
1579** Registers
1580
1581*** `C-x r +' is now overloaded to invoke `append-to-register'.
1582
1583*** New option `register-separator' specifies the register containing
1584the text to put between collected texts for use with
1585M-x append-to-register and M-x prepend-to-register.
1586
1587
1588* Changes in Specialized Modes and Packages in Emacs 24.3
1589
1590** Common Lisp emulation (CL)
1591
1592*** CL's main entry is now (require 'cl-lib).
1593`cl-lib' is like the old `cl' except that it uses the namespace cleanly;
1594i.e., all its definitions have the "cl-" prefix (and internal definitions
1595use the "cl--" prefix).
1596
1597If `cl' provided a feature under the name `foo', then `cl-lib'
1598provides it under the name `cl-foo' instead; with the exceptions of the
1599few `cl' definitions that had to use `foo*' to avoid conflicts with
1600pre-existing Elisp entities. These have been renamed to `cl-foo'
1601rather than `cl-foo*'.
1602
1603The old `cl' is now deprecated and is mainly just a bunch of aliases that
1604provide the old, non-prefixed names. Some exceptions are listed below:
1605
1606*** `cl-flet' is not like `flet' (which is deprecated).
1607Instead it obeys the behavior of Common-Lisp's `flet'.
1608In particular, in cl-flet function definitions are lexically scoped,
1609whereas in flet the scoping is dynamic.
1610
1611*** `cl-labels' is slightly different from `labels'.
1612The difference is that it relies on the `lexical-binding' machinery
1613(as opposed to the `lexical-let' machinery used previously) to capture
1614definitions in closures, so such closures will only work if `lexical-binding'
1615is in use.
1616
1617*** `cl-letf' is not exactly like `letf'.
1618The only difference is in details that relate to some deprecated usage
1619of `symbol-function' in place forms.
1620
1621*** `progv' was rewritten to use the `let' machinery.
1622A side effect is that variables without corresponding values are bound
1623to nil rather than being made unbound.
1624
1625*** The following methods of extending `setf' are obsolete
1626(use features from gv.el instead):
1627`define-modify-macro' (use `gv-letplace')
1628`defsetf' (use `gv-define-simple-setter' or `gv-define-setter')
1629`define-setf-expander' (use `gv-define-setter' or `gv-define-expander')
1630`get-setf-method' no longer exists (see "Incompatible Lisp Changes")
1631
1632** Diff mode
1633
1634*** Changes are now highlighted using the same color scheme as in
1635modern VCSes. Deletions are displayed in red (new faces
1636`diff-refine-removed' and `smerge-refined-removed', and new definition
1637of `diff-removed'), insertions in green (new faces `diff-refine-added'
1638and `smerge-refined-added', and new definition of `diff-added').
1639
1640*** The variable `diff-use-changed-face' defines whether to use the
1641face `diff-changed', or `diff-removed' and `diff-added' to highlight
1642changes in context diffs.
1643
1644*** The new command `diff-delete-trailing-whitespace' removes trailing
1645whitespace introduced by a diff.
1646
1647** Ediff now uses the same color scheme as Diff mode.
1648
1649** Python mode
1650
1651A new version of python.el, which provides several new features, including:
1652per-buffer shells, better indentation, Python 3 support, and improved
1653shell-interaction compatible with iPython (and virtually any other
1654text based shell).
1655
1656*** Some user options have been replaced/renamed, including (old -> new):
1657**** python-indent -> python-indent-offset
1658**** python-guess-indent -> python-indent-guess-indent-offset
1659**** python-pdbtrack-do-tracking-p -> python-pdbtrack-activate
1660**** python-use-skeletons -> python-skeleton-autoinsert
1661
1662*** Some user options have been removed, including:
1663
1664**** `python-indent-string-contents': Strings are never indented.
1665
1666**** `python-honour-comment-indentation':
1667Comments are always considered as indentation markers.
1668
1669**** `python-continuation-offset': Indentation is automatically
1670calculated in a pep8 compliant way depending on the context.
1671
1672**** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist':
1673Have no direct mapping as the shell interaction is completely different.
1674
1675**** `python-python-command', `python-jython-command':
1676Replaced by `python-shell-interpreter'.
1677
1678**** `inferior-python-filter-regexp', `python-remove-cwd-from-path',
1679`python-pdbtrack-minor-mode-string', `python-source-modes':
1680No longer relevant.
1681
1682*** Some commands have been replaced (old -> new):
1683**** python-insert-class -> python-skeleton-class
1684**** python-insert-def -> python-skeleton-def
1685**** python-insert-for -> python-skeleton-for
1686**** python-insert-if -> python-skeleton-if
1687**** python-insert-try/except -> python-skeleton-try
1688**** python-insert-try/finally -> python-skeleton-try
1689**** python-insert-while -> python-skeleton-while
1690**** python-find-function -> python-nav-jump-to-defun
1691**** python-next-statement -> python-nav-forward-sentence
1692**** python-previous-statement -> python-nav-backward-sentence
1693**** python-beginning-of-defun-function -> python-nav-beginning-of-defun
1694**** python-end-of-defun-function -> python-nav-end-of-defun
1695**** python-send-buffer -> python-shell-send-buffer
1696**** python-send-defun -> python-shell-send-defun
1697**** python-send-region -> python-shell-send-region
1698**** python-send-region-and-go -> emulate with python-shell-send-region
1699and python-shell-switch-to-shell
1700**** python-send-string -> python-shell-send-string
1701**** python-switch-to-python -> python-shell-switch-to-shell
1702**** python-describe-symbol -> python-eldoc-at-point
1703
1704** D-Bus
1705
1706*** New variables `dbus-compiled-version' and `dbus-runtime-version'.
1707
1708*** The D-Bus object manager interface is implemented.
1709
1710*** Variables of type :(u)int32 and :(u)int64 accept floating points,
1711if their value does not fit into Emacs's integer range.
1712
1713*** The function `dbus-call-method' is now non-blocking.
1714It can be interrupted by `C-g'. `dbus-call-method-non-blocking' is obsolete.
1715
1716*** Signals can also be sent as unicast messages.
1717
1718*** The argument list of `dbus-register-signal' has been extended,
1719according to the new match rule types of D-Bus.
1720
1721*** `dbus-init-bus' supports private connections.
1722
1723*** There is a new function `dbus-setenv'.
1724
1725** `desktop-path' no longer includes the "." directory.
1726Desktop files are now located in ~/.emacs.d by default.
1727
1728** Dired
1729
1730*** `dired-do-async-shell-command' executes each file sequentially
1731if the command ends in `;' (when operating on multiple files).
1732Otherwise, it executes the command on each file in parallel.
1733
1734*** Typing `M-n' in the minibuffer of `dired-do-chmod', `dired-do-chgrp',
1735`dired-do-chown', and `dired-do-touch' yanks the attributes of the
1736file at point.
1737
1738*** When the region is active, `m' (`dired-mark'), `u' (`dired-unmark'),
1739`DEL' (`dired-unmark-backward'), and `d' (`dired-flag-file-deletion')
1740mark/unmark/flag all files in the active region.
1741
1742*** The minibuffer default for `=' (`dired-diff') has changed.
1743It is now the backup file for the file at point, if one exists.
1744In Transient Mark mode the default is the file at the active mark.
1745
1746*** `M-=' is no longer bound to `dired-backup-diff' in Dired buffers.
1747The global binding for `M-=', `count-words-region' is in effect.
1748
1749** ERC
1750
1751*** New module "notifications", which can send a notification when you
1752receive a private message or your nickname is mentioned.
1753
1754*** ERC will look up server/channel names via auth-source and use any
1755channel keys found.
1756
1757*** New option `erc-lurker-hide-list', similar to `erc-hide-list', but
1758only applies to messages sent by lurkers.
1759
1760** reStructuredText mode
1761
1762*** Keybindings (see `C-c C-h'), TAB indentation, filling and auto-filling,
1763fontification, comment handling, and customization have all been revised
1764and improved.
1765
1766*** Support for `imenu' and `which-function-mode'.
1767
1768*** The reStructuredText syntax is more closely covered.
1769Sphinx support has been improved.
1770
1771*** `rst-insert-list' inserts new list or continues existing lists.
1772
1773*** A negative prefix argument always works for `rst-adjust'.
1774
1775*** The window configuration is reset after displaying a TOC.
1776
1777*** The constant `rst-version' describes the rst.el package version.
1778
1779** Ruby mode
1780
1781*** Support for percent literals and recognition of regular expressions
1782in method calls without parentheses with more methods, including Cucumber
1783steps definitions.
1784
1785*** Improved syntax highlighting and indentation.
1786
1787*** New command `ruby-toggle-block', bound to `C-c {'.
1788
1789*** Some non-standard keybindings/commands have been removed:
1790
1791**** `ruby-electric-brace'; use `electric-indent-mode' instead.
1792
1793**** `ruby-mark-defun'; use `mark-defun'.
1794
1795**** `ruby-beginning-of-defun' and `ruby-end-of-defun' are replaced by
1796appropriate settings for the variables `beginning-of-defun-function'
1797and `end-of-defun-function'.
1798
1799**** Non-standard keybindings for `backward-kill-word', `comment-region',
1800`reindent-then-newline-and-indent' and `newline' have been removed.
1801
1802** Shell Script mode
1803
1804*** Pairing of parens/quotes uses `electric-pair-mode' instead of skeleton-pair.
1805
1806*** `sh-electric-here-document-mode' now controls auto-insertion of here-docs.
1807
1808*** `sh-use-smie' lets you choose a new indentation and navigation code.
1809
1810** VHDL mode
1811
1812*** The free software compiler GHDL is supported (and now the default).
1813
1814*** Support for the VHDL-AMS packages has been added/updated.
1815
1816*** Updated to the 2002 revision of the VHDL standard.
1817
1818*** Accepts \r and \f as whitespace.
1819
1820** Apropos
1821
1822*** The faces used by Apropos are now directly customizable.
1823These faces are named `apropos-symbol', `apropos-keybinding', and so on;
1824see the `apropos' Custom group for details.
1825
1826*** The old options whose values specified faces to use have been removed
1827(i.e. `apropos-symbol-face', `apropos-keybinding-face', `apropos-label-face',
1828`apropos-match-face' and `apropos-property-face'.).
1829
1830** Buffer Menu
1831
1832*** This package has been rewritten to use Tabulated List mode.
1833
1834*** Option `Buffer-menu-buffer+size-width' is now obsolete.
1835Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead.
1836
1837** Calc
1838
1839*** Algebraic simplification mode is now the default.
1840To restrict to the limited simplifications given by the former
1841default simplification mode, use `m I'.
1842
1843** Calendar
1844
1845*** You can customize the header text that appears above each calendar month.
1846See the variable `calendar-month-header'.
1847
1848*** New LaTeX calendar style, produced by `cal-tex-cursor-week2-summary'.
1849
1850*** The calendars produced by cal-html include holidays.
1851Customize `cal-html-holidays' to change this.
1852
1853** CEDET
1854
1855*** The major modes from the parser generators "Bovine" and "Wisent"
1856are now properly integrated in Emacs. The file suffixes ".by" and ".wy"
1857are in `auto-mode-alist', and the corresponding manuals are included.
1858
1859*** EDE
1860
1861**** Menu support for the "Configuration" feature. This allows users to
1862choose the active configuration (such as debug or install) from the menu.
1863
1864**** New command `ede-set' to interactively set project-local variables.
1865
1866**** Support for compiling, debugging, and running in "generic" projects.
1867
1868**** Autoconf editing support for M4 macros with complex arguments.
1869
1870**** Compilation support for the "linux" project type.
1871
1872**** "simple" projects have been removed; use "generic" projects instead.
1873
1874*** Semantic
1875
1876**** Support for parsing #include statements inside a namespace in C/C++.
1877
1878**** Improved support for 'extern "C"' declarations in C/C++.
1879
1880**** The ability to ignore more common special C/C++ preprocessor symbols,
1881such as '__nonnull' and '__asm'. Add '__cplusplus' macro when parsing C++.
1882If available, include cdefs.h as an additional source of preprocessor symbols.
1883
1884**** Improved C/C++ function pointer parsing.
1885
1886**** In Python, support for converting imports to include file names.
1887
1888**** Ability to dynamically determine the Python load path.
1889
1890**** Support for the Python 'WITH' and 'AT' keywords.
1891
1892**** Improved tooltip completion.
1893
1894*** SRecode
1895
1896**** The SRecode manual is now included.
1897
1898**** Tag generation supports constructor/destructor settings and system
1899include differentiation.
1900
1901**** Addition of 'Framework' support: Frameworks are specified when a
1902particular kind of library (such as Android) is needed in a common language
1903mode (like Java).
1904
1905**** Support for nested templates and let variables override based on priority.
1906
1907**** Support for merging tables from multiple related modes, such as
1908default -> c++ -> arduino.
1909
1910** Compile has a new option `compilation-always-kill'.
1911
1912** Customize
1913
1914*** `custom-reset-button-menu' now defaults to t.
1915
1916*** Non-option variables are never matched in `customize-apropos' and
1917`customize-apropos-options' (i.e., the prefix argument does nothing for
1918these commands now).
1919
1920** Term
1921
1922*** The variables `term-default-fg-color' and `term-default-bg-color'
1923are now deprecated in favor of the customizable face `term'.
1924
1925*** You can customize how to display ANSI terminal colors and styles
1926by customizing the corresponding `term-color-<COLOR>',
1927`term-color-underline' and `term-color-bold' faces.
1928
1929** Tramp
1930
1931*** The syntax has been extended in order to allow ad-hoc proxy definitions.
1932
1933*** Remote processes are now also supported on remote MS-Windows hosts.
1934
1935** URL
1936
1937*** Structs made by `url-generic-parse-url' have nil `attributes' slot.
1938Previously, this slot stored semicolon-separated attribute-value pairs
1939appended to some imap URLs, but this is not compatible with RFC 3986.
1940So now the `filename' slot stores the entire path and query components,
1941and the `attributes' slot is always nil.
1942
1943*** New function `url-encode-url' for encoding a URI string.
1944The `url-retrieve' function now uses this to encode its URL argument,
1945in case that is not properly encoded.
1946
1947** notifications.el supports now version 1.2 of the Notifications API.
1948The function `notifications-get-capabilities' returns the supported
1949server properties.
1950
1951** Flymake uses fringe bitmaps to indicate errors and warnings.
1952See `flymake-fringe-indicator-position', `flymake-error-bitmap' and
1953`flymake-warning-bitmap'.
1954
1955** The FFAP option `ffap-url-unwrap-remote' can now be a list of strings,
1956specifying URL types that should be converted to remote file names at
1957the FFAP prompt. The default is now '("ftp").
1958
1959** New Ibuffer `derived-mode' filter, bound to `/ M'.
1960The old binding for `/ M' (filter by used-mode) is now bound to `/ m'.
1961
1962** New option `mouse-avoidance-banish-position' specifies where the
1963`banish' mouse avoidance setting moves the mouse.
1964
1965** In Perl mode, new option `perl-indent-parens-as-block' causes non-block
1966closing brackets to be aligned with the line of the opening bracket.
1967
1968** In Proced mode, new command `proced-renice' renices marked processes.
1969
1970** New option `async-shell-command-buffer' specifies the buffer to use
1971for a new asynchronous `shell-command' when the default output buffer
1972`*Async Shell Command*' is already in use.
1973
1974** SQL mode has a new option `sql-db2-escape-newlines'.
1975If non-nil, newlines sent to the command interpreter will be escaped
1976by a backslash. The default does not escape the newlines and assumes
1977that the sql statement will be terminated by a semicolon.
1978
1979** New command `tabulated-list-sort', bound to `S' in Tabulated List mode
1980(and modes that derive from it), sorts the column at point, or the Nth
1981column if a numeric prefix argument is given.
1982
1983** `which-func-modes' now defaults to t, so Which Function mode, when
1984enabled, applies to all applicable major modes.
1985
1986** `winner-mode-hook' now runs when the mode is disabled, as well as when
1987it is enabled.
1988
1989** Follow mode no longer works by using advice.
1990The option `follow-intercept-processes' has been removed.
1991
1992** `javascript-generic-mode' is now an obsolete alias for `js-mode'.
1993
1994** Hooks renamed to avoid obsolete "-hooks" suffix:
1995*** semantic-lex-reset-hooks -> semantic-lex-reset-functions
1996*** semantic-change-hooks -> semantic-change-functions
1997*** semantic-edits-new-change-hooks -> semantic-edits-new-change-functions
1998*** semantic-edits-delete-change-hooks -> semantic-edits-delete-change-functions
1999*** semantic-edits-reparse-change-hooks -> semantic-edits-reparse-change-functions
2000*** semanticdb-save-database-hooks -> semanticdb-save-database-functions
2001*** c-prepare-bug-report-hooks -> c-prepare-bug-report-hook
2002*** rcirc-sentinel-hooks -> rcirc-sentinel-functions
2003*** rcirc-receive-message-hooks -> rcirc-receive-message-functions
2004*** rcirc-activity-hooks -> rcirc-activity-functions
2005*** rcirc-print-hooks -> rcirc-print-functions
2006*** dbus-event-error-hooks -> dbus-event-error-functions
2007*** eieio-pre-method-execution-hooks -> eieio-pre-method-execution-functions
2008*** checkdoc-style-hooks -> checkdoc-style-functions
2009*** checkdoc-comment-style-hooks -> checkdoc-comment-style-functions
2010*** archive-extract-hooks -> archive-extract-hook
2011*** filesets-cache-fill-content-hooks -> filesets-cache-fill-content-hook
2012*** hfy-post-html-hooks -> hfy-post-html-hook
2013*** nndiary-request-create-group-hooks -> nndiary-request-create-group-functions
2014*** nndiary-request-update-info-hooks -> nndiary-request-update-info-functions
2015*** nndiary-request-accept-article-hooks -> nndiary-request-accept-article-functions
2016*** gnus-subscribe-newsgroup-hooks -> gnus-subscribe-newsgroup-functions
2017
2018** Obsolete packages
2019
2020*** assoc.el
2021In most cases, assoc+member+push+delq work just as well.
2022And in any case it's just a terrible package: ugly semantics, terrible
2023inefficiency, and not namespace-clean.
2024*** bruce.el
2025*** cust-print.el
2026*** ledit.el
2027*** mailpost.el
2028*** mouse-sel.el
2029*** patcomp.el
2030
2031
2032* Incompatible Lisp Changes in Emacs 24.3
2033
2034** Docstrings starting with `*' no longer indicate user options.
2035Only variables defined using `defcustom' are considered user options.
2036The function `user-variable-p' is now an obsolete alias for
2037`custom-variable-p'.
2038
2039** The return values of `defalias', `defun' and `defmacro' have changed,
2040and are now undefined. For backwards compatibility, `defun' and
2041`defmacro' currently return the name of the newly defined
2042function/macro, but this should not be relied upon.
2043
2044** `random' by default now returns a different random sequence in
2045every Emacs run. Use `(random S)', where S is a string, to set the
2046random seed to a value based on S, in order to get a repeatable
2047sequence in later calls.
2048
2049** If the NEWTEXT arg to `replace-match' contains a substring "\?",
2050that substring is inserted literally even if the LITERAL arg is
2051non-nil, instead of causing an error to be signaled.
2052
2053** `select-window' now always makes the window's buffer current.
2054It does so even if the window was selected before.
2055
2056** The function `x-select-font' can return a font spec, instead of a
2057font name as a string. Whether it returns a font spec or a font name
2058depends on the graphical library.
2059
2060** `face-spec-set' no longer sets frame-specific attributes when the
2061third argument is a frame (that usage was obsolete since Emacs 22.2).
2062
2063** `set-buffer-multibyte' now signals an error in narrowed buffers.
2064
2065** The CL package's `get-setf-method' function no longer exists.
2066Generalized variables are now part of core Emacs Lisp, and implemented
2067differently to the way cl.el used to do it. It is not possible to
2068define a compatible replacement for `get-setf-method'. See the file
2069gv.el for internal details of the new implementation.
2070
2071** The arguments of `dbus-register-signal' are no longer just strings,
2072but keywords or keyword-string pairs. The old argument list will
2073still be supported for Emacs 24.x.
2074
2075** Miscellaneous name changes
2076Some Lisp symbols have been renamed to correct their spelling,
2077or to be more consistent with standard Emacs terminology.
2078
2079*** Renamed functions
2080**** hangul-input-method-inactivate -> hangul-input-method-deactivate
2081**** inactivate-input-method -> deactivate-input-method
2082**** quail-inactivate -> quail-deactivate
2083**** robin-inactivate -> robin-deactivate
2084**** viper-inactivate-input-method -> viper-deactivate-input-method
2085**** viper-inactivate-input-method-action ->
2086 viper-deactivate-input-method-action
2087**** ucs-input-inactivate -> ucs-input-deactivate
2088
2089*** Renamed hooks
2090The old hooks are still supported for backward compatibility, but they
2091are deprecated and will be removed eventually.
2092**** input-method-inactivate-hook -> input-method-deactivate-hook
2093**** robin-inactivate-hook -> robin-deactivate-hook
2094**** quail-inactivate-hook -> quail-deactivate-hook
2095
2096*** Renamed variables
2097**** follow-deactive-menu -> follow-inactive-menu
2098**** inactivate-current-input-method-function ->
2099 deactivate-current-input-method-function
2100
2101** Some obsolete functions, variables, and faces have been removed:
2102*** `last-input-char', `last-command-char', `unread-command-char'
2103*** `facemenu-unlisted-faces'
2104*** `rmail-decode-mime-charset'
2105*** `iswitchb-read-buffer'
2106*** `sc-version', `sc-submit-bug-report'
2107*** `set-char-table-default'
2108*** `string-to-sequence' (use `string-to-list' or `string-to-vector')
2109*** `compile-internal'
2110*** `modeline'
2111*** `mode-line-inverse-video'
2112*** `follow-mode-off-hook'
2113*** `cvs-commit-buffer-require-final-newline'
2114(use `log-edit-require-final-newline' instead)
2115*** `cvs-changelog-full-paragraphs'
2116(use `log-edit-changelog-full-paragraphs' instead)
2117*** `cvs-diff-ignore-marks', `cvs-diff-buffer-name'
2118*** `vc-ignore-vc-files' (use `vc-handled-backends' instead)
2119*** `vc-master-templates' (use `vc-handled-backends' instead)
2120*** `vc-checkout-carefully'
2121
2122
2123* Lisp Changes in Emacs 24.3
2124
2125** CL-style generalized variables are now in core Elisp.
2126`setf' is autoloaded; `push' and `pop' accept generalized variables.
2127You can define your own generalized variables using `gv-define-simple-setter',
2128`gv-define-setter', etc.
2129
2130** Emacs tries to macroexpand interpreted (non-compiled) files during load.
2131This can significantly speed up execution of non-byte-compiled code,
2132but can also bump into previously unnoticed cyclic dependencies.
2133These are generally harmless: they will simply cause the macro calls
2134to be left for later expansion (as before), but will result in a
2135warning ("Eager macro-expansion skipped due to cycle") describing the cycle.
2136You may wish to restructure your code so this does not happen.
2137
2138** New sampling-based Elisp profiler.
2139Try M-x profiler-start, do some work, and then call M-x profiler-report.
2140When finished, use M-x profiler-stop. The sampling rate can be based on
2141CPU time or memory allocations.
2142
2143** `defun' also accepts a (declare DECLS) form, like `defmacro'.
2144The interpretation of the DECLS is determined by `defun-declarations-alist'.
2145
2146** New macros `setq-local' and `defvar-local'.
2147
2148** Face underlining can now use a wave.
2149
2150** `read-regexp' has a new argument HISTORY; the first argument PROMPT
2151of `read-regexp' accepts a string ending with a colon and space, and its
2152second argument DEFAULTS can be a list of strings accessible via `M-n'
2153in the minibuffer ahead of other hard-coded useful regexp-related values.
2154More commands use `read-regexp' now to read their regexp arguments.
2155
2156** Completion
2157
2158*** New function `completion-table-with-quoting' to handle completion
2159in the presence of quoting, such as file completion in shell buffers.
2160
2161*** New function `completion-table-subvert' to use an existing completion
2162table, but with a different prefix.
2163
2164** Debugger
2165
2166*** New error type and new function `user-error'.
2167These do not trigger the debugger.
2168
2169*** New option `debugger-bury-or-kill', saying what to do with the
2170debugger buffer when exiting debug.
2171
2172*** Set `debug-on-message' to enter the debugger when a certain
2173message is displayed in the echo area. This can be useful when trying
2174to work out which code is doing something.
2175
2176*** New var `inhibit-debugger', automatically set to prevent accidental
2177recursive invocations.
2178
2179** Window handling
2180
2181*** New command `fit-frame-to-buffer' adjusts the frame height to
2182fit the contents.
2183
2184*** The command `fit-window-to-buffer' can adjust the frame height
2185if the new option `fit-frame-to-buffer' is non-nil.
2186
2187*** New macro `with-temp-buffer-window', similar to
2188`with-output-to-temp-buffer'.
2189
2190*** `temp-buffer-resize-mode' no longer resizes windows that have been
2191reused.
2192
2193*** New option `switch-to-buffer-preserve-window-point' to restore a
2194window's point when switching buffers.
2195
2196*** New display action alist entries `window-height' and `window-width'
2197specify the size of new windows created by `display-buffer'.
2198
2199*** New display action alist entry `pop-up-frame-parameters', if
2200non-nil, specifies frame parameters to give any newly-created frame.
2201
2202*** New display action alist entry `inhibit-switch-frame', if non-nil,
2203tells display action functions to avoid changing which frame is
2204selected.
2205
2206*** New display action alist entry `previous-window', if non-nil,
2207specifies window to reuse in `display-buffer-in-previous-window'.
2208
2209*** New display action functions `display-buffer-below-selected',
2210and `display-buffer-in-previous-window'.
2211
2212*** The functions `get-lru-window', `get-mru-window' and `get-largest-window'
2213now accept a third argument to avoid choosing the selected window.
2214
2215*** Additional values recognized for option `window-combination-limit'.
2216
2217*** The following variables are obsolete, as they can be replaced by
2218appropriate entries in the `display-buffer-alist' function introduced
2219in Emacs 24.1:
2220**** `dired-shrink-to-fit'
2221**** `display-buffer-reuse-frames'
2222**** `display-buffer-function'
2223**** `special-display-buffer-names'
2224**** `special-display-frame-alist'
2225**** `special-display-function'
2226**** `special-display-regexps'
2227
2228** Time
2229
2230*** `current-time-string' no longer requires that its argument's year
2231must be in the range 1000..9999. It now works with any year supported
2232by the underlying C implementation.
2233
2234*** `current-time' now returns extended-format time stamps
2235(HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds.
2236PSEC is typically a multiple of 1000 on current machines. Other
2237functions that use this format, such as `file-attributes' and
2238`format-time-string', have been changed accordingly. Old-format time
2239stamps are still accepted.
2240
2241*** The format of timers in `timer-list' and `timer-idle-list' is now
2242[TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS].
2243The PSECS slot is new, and uses picosecond resolution. It can be
2244accessed via the new `timer--psecs' accessor.
2245
2246*** Last-modified time stamps in undo lists now are of the form
2247(t HI-SECS LO-SECS USECS PSECS) instead of (t HI-SECS . LO-SECS).
2248
2249** EIEIO
2250
2251*** Improved security when handling persistent objects:
2252
2253**** `eieio-persistent-read' now features optional arguments for specifying
2254the class to load, as well as a flag stating whether subclasses are allowed;
2255if provided, other classes will be rejected by the reader. For
2256compatibility with existing code, if the class is omitted only a
2257warning is issued.
2258
2259**** New specialized reader for pulling in classes and signaling errors
2260without evaluation of suspicious code.
2261
2262**** All slots that contain objects must have a :type. Slots with lists
2263of objects must use a new type predicate for a list of an object type.
2264
2265*** Support for `find-function' and similar utilities, through the addition
2266of filename support to generated symbols.
2267
2268** Floating point functions now always return special values like NaN,
2269instead of signaling errors, if given invalid args; e.g., (log -1.0).
2270Previously, they returned NaNs on some platforms but signaled errors
2271on others. The affected functions are acos, asin, tan, exp, expt,
2272log, log10, sqrt, and mod.
2273
2274** New fringe bitmap `exclamation-mark'.
2275
2276** Miscellaneous changes to special forms and macros
2277
2278*** `defun' and `defmacro' are now macros rather than special forms.
2279
2280*** `kbd' is now a function rather than a macro.
2281
2282** Miscellaneous new functions
2283
2284*** `set-temporary-overlay-map' sets up a temporary keymap that
2285takes precedence over most other maps for a short while (normally one key).
2286
2287*** `autoloadp' tests if its argument is an autoloaded object.
2288
2289*** `autoload-do-load' performs the autoloading operation.
2290
2291*** `buffer-narrowed-p' tests if the buffer is narrowed.
2292
2293*** `file-name-base' returns a file name sans directory and extension.
2294
2295*** `function-get' fetches a function property, following aliases.
2296
2297*** `posnp' tests if an object is a `posn'.
2298
2299*** `system-users' returns the user names on the system.
2300
2301*** `system-groups' returns the group names on the system.
2302
2303*** `tty-top-frame' returns the topmost frame of a text terminal.
2304
2305** The following functions and variables are obsolete:
2306*** `automount-dir-prefix' (use `directory-abbrev-alist')
2307*** `buffer-has-markers-at'
2308*** `macro-declaration-function' (use `macro-declarations-alist')
2309*** `window-system-version' (provides no useful information)
2310*** `dired-pop-to-buffer' (use `dired-mark-pop-up')
2311*** `query-replace-interactive'
2312*** `font-list-limit' (has had no effect since Emacs < 23)
2313
2314
2315* Changes in Emacs 24.3 on Non-Free Operating Systems
2316
2317** Cygwin builds can use the native MS Windows user interface.
2318Pass `--with-w32' to configure. The default remains the X11 interface.
2319
2320** Two new functions are available in Cygwin builds:
2321`cygwin-convert-file-name-from-windows' and
2322`cygwin-convert-file-name-to-windows'. These functions allow Lisp
2323code to access the Cygwin file-name mapping machinery to convert
2324between Cygwin and Windows-native file and directory names.
2325
2326** When invoked with the -nw switch to run on the Windows text-mode terminal,
2327Emacs now supports `mouse-highlight', help-echo (in the echo area), and
2328`mouse-autoselect-window'.
2329
2330** On MS Windows Vista and later Emacs now supports symbolic links.
2331
2332** On MS Windows, you can pass `--without-libxml2' to configure.bat to omit
2333support for libxml2, even if its presence is detected.
2334
2335** On Mac OS X, the Nextstep port requires OS X 10.4 or later.
2336
2337** On Mac OS X, configure no longer automatically adds the Fink "/sw"
2338directories to the search path. You must add them yourself if you want them.
2339
2340
2341* Changes in Emacs 24.2
2342
2343** This is mainly a bug-fix release.
2344
2345
2346* Installation Changes in Emacs 24.1
2347
2348** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
2349to configure. Note that other libraries used by Emacs, RSVG and GConf,
2350also depend on Gtk+. You can disable them with --without-rsvg and
2351--without-gconf.
2352
2353** Emacs can be compiled with GnuTLS support.
2354This happens by default if a suitably recent version of the library is
2355found at build time. To prevent this, use the configure option
2356`--without-gnutls'. See below for GnuTLS features.
2357
2358** Emacs can be compiled with SELinux support.
2359This happens by default if a suitably recent version of the library is
2360found at build time. To prevent this, use the configure option
2361`--without-selinux'. See below for SELinux features.
2362
2363** Emacs can be compiled with ImageMagick support.
2364This happens by default if a suitably recent version of the library is
2365found at build time. To prevent this, use the configure option
2366`--without-imagemagick'. See below for ImageMagick features.
2367This feature is not available for the Nextstep or MS ports.
2368
2369** Emacs can be compiled with libxml2 support.
2370This happens by default if a suitably recent version of the library is
2371found at build time. To prevent this, use the configure option
2372`--without-xml2'. See below for libxml2 features.
2373
2374** By default, the installed Info and man pages are compressed.
2375You can disable this by configuring --without-compress-info.
2376
2377** New configure option --with-wide-int.
2378With it, Emacs integers typically have 62 bits, even on 32-bit machines.
2379On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB
2380to about 2 GiB.
2381
2382** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost.
2383These provide no new functionality, they just remove the need to edit
2384lib-src/Makefile by hand in order to use the associated features.
2385
2386** New configure option --enable-use-lisp-union-type.
2387This is only useful for Emacs developers to debug certain types of bugs.
2388This is not a new feature; only the configure flag is new.
2389
2390** The standalone programs digest-doc and sorted-doc are removed.
2391Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'.
2392
2393** The standalone program `fakemail' is removed.
2394If you need it, feedmail.el provides a superset of the functionality.
2395
2396
2397* Startup Changes in Emacs 24.1
2398
2399** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
2400command line arguments, and the EMACS_UNIBYTE environment variable, no
2401longer have any effect. (They were declared obsolete in Emacs 23.)
2402
2403** New command line option `--no-site-lisp' removes site-lisp directories
2404from load-path. -Q now implies this. This option does not affect the
2405EMACSLOADPATH environment variable (and hence has no effect for
2406Nextstep builds).
2407
2408
2409* Changes in Emacs 24.1
2410
2411** Completion
2412
2413*** Many packages now use the `completion-at-point' command,
2414rather than implementing separate completion commands.
2415
2416*** `completion-at-point' now handles tags and semantic completion.
2417
2418*** Completion in a non-minibuffer now tries to detect the end of completion
2419and pops down the *Completions* buffer accordingly.
2420
2421*** New option `completion-cycle-threshold' allows completion cycling.
2422
2423*** New option `completion-category-overrides' for overriding the
2424default completion style in certain circumstances.
2425
2426*** New completion style `substring'.
2427
2428*** Completion of buffer names uses `substring' completion by default.
2429
2430*** The option `widget-complete-field' has been removed.
2431
2432** Mail changes
2433
2434*** The first time you try sending mail, Emacs asks for a mail method.
2435This is implemented by a new default for `send-mail-function', which
2436is `sendmail-query-once'. This offers to use the smtpmail package, or
2437to use the old defaults relying on external mail facilities
2438(`sendmail-send-it' on GNU/Linux and other Unix-like systems, and
2439`mailclient-send-it' on Windows).
2440
2441*** Typing `C-c m' in the buffer made by `M-x report-emacs-bug'
2442transfers the report to your desktop's preferred mail client, if there
2443is one. This uses either the "xdg-email" utility, or Mac OS's "open"
2444command.
2445
2446*** See Changes in Specialized Modes and Packages for SMTPmail changes
2447and Mail mode changes
2448
2449** Emacs server and client changes
2450
2451*** New option `server-port' specifies the port for TCP Emacs servers.
2452
2453*** New emacsclient argument -q/--quiet suppresses some status messages.
2454
2455*** New emacsclient argument --frame-parameters specifies the frame
2456parameters of any newly-created graphical frame.
2457
2458*** If emacsclient shuts down due to Emacs signaling an error,
2459its exit status is 1.
2460
2461*** New emacsclient argument --parent-id ID.
2462This opens a client frame in parent X window ID, via XEmbed, similar
2463to the --parent-id argument to Emacs.
2464
2465** Internationalization changes
2466
2467*** Emacs now supports display and editing of bidirectional text.
2468Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are
2469displayed in the correct visual order as expected by users of those
2470scripts. The display reordering is a "full bidirectionality" class
2471implementation of the Unicode Bidirectional Algorithm (UBA). Buffers
2472with no RTL text should look exactly the same as before.
2473
2474**** New buffer-local variable `bidi-display-reordering'.
2475To disable display reordering in a buffer, change this to nil.
2476
2477**** New buffer-local variable `bidi-paragraph-direction'.
2478If nil (the default), Emacs determines the base direction of each
2479paragraph from its text, as specified by the UBA. Setting the value
2480to `right-to-left' or `left-to-right' forces a base direction on each
2481paragraph.
2482
2483Paragraphs with right-to-left base direction are displayed starting at
2484the right window edge.
2485
2486*** Enhanced support for characters with no glyphs in available fonts,
2487or, on text terminals, characters that cannot be encoded by the
2488terminal coding system. The new option `glyphless-char-display-control'
2489specifies how to display them: as a hexadecimal code in a box, a thin
24901-pixel space, an empty box, etc.
2491
2492*** New input methods for Farsi and Bulgarian
2493(farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic).
2494
2495*** `nobreak-char-display' now also highlights Unicode hyphen chars
2496(U+2010 and U+2011).
2497
2498*** New Hebrew translation of the Emacs Tutorial.
2499Type `C-u C-h t' to choose it in case your language setup doesn't
2500automatically select it.
2501
2502** An Emacs Lisp package manager is now included.
2503This is a convenient way to download and install additional packages,
2504from a package repository at http://elpa.gnu.org.
2505
2506*** M-x list-packages shows a list of packages, which can be
2507selected for installation.
2508
2509*** New command `describe-package', bound to `C-h P'.
2510
2511*** By default, all installed packages are loaded automatically when
2512Emacs starts up. To disable this, set `package-enable-at-startup' to
2513nil. To specify the packages to load, customize `package-load-list'.
2514
2515** Custom theme changes
2516
2517*** New command `M-x customize-themes', which provides a convenient
2518interface for enabling and disabling Custom themes.
2519
2520*** New option `custom-theme-load-path' is the load path for themes.
2521Emacs no longer looks for Custom themes in `load-path'. The default
2522value of `custom-theme-load-path' says to look for themes in
2523`custom-theme-directory', followed by a subdirectory of
2524`data-directory' named "themes/", which contains a small selection of
2525built-in Custom themes.
2526
2527*** New option `custom-safe-themes' records known-safe theme files.
2528If a theme is not in this list, Emacs queries before loading it, and
2529offers to save the theme to `custom-safe-themes' automatically. By
2530default, all themes included in Emacs are treated as safe.
2531
2532** Improved GTK integration
2533
2534*** GTK scroll-bars are now placed on the right by default.
2535The function `set-scroll-bar-mode' can change this.
2536
2537*** GTK tool bars can have just text, just images or images and text.
2538Customize `tool-bar-style' to choose the style. On a Gnome desktop,
2539the default is taken from desktop settings.
2540
2541*** GTK tool bars can be placed on any edge of the frame.
2542The frame-parameter tool-bar-position controls this. It takes the
2543values top, left, right or bottom. The Options => Show/Hide menu has
2544entries for this.
2545
2546*** The default colors for selected text (the `region' face) are taken
2547from the GTK theme when Emacs is built with GTK.
2548
2549*** Emacs uses GTK tooltips by default if built with GTK.
2550You can disable this by changing `x-gtk-use-system-tooltips' to nil.
2551
2552** Graphical interface changes
2553
2554*** On graphical displays, the mode-line no longer ends in dashes.
2555Also, the first dash (which does not indicate anything) is just
2556displayed as a space.
2557
2558*** `menu-bar-select-buffer-function' lets you choose another operation
2559instead of `switch-to-buffer' when selecting an item in the Buffers menu.
2560
2561*** Lucid menus and dialogs can display antialiased fonts if Emacs is
2562built with Xft. These fonts can be set via X resources, for example:
2563Emacs.pane.menubar.font: Courier-12
2564
2565** Exiting changes
2566
2567*** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP,
2568or if it receives a SIGINT signal in batch mode.
2569
2570*** `kill-emacs-hook' is now also run in batch mode.
2571Third-party code which adds to `kill-emacs-hook' should check if they
2572do the right thing in batch mode.
2573
2574** Scrolling changes
2575
2576*** New scrolling commands `scroll-up-command' and `scroll-down-command'
2577(bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom
2578of buffer at first key-press (instead they move to top/bottom of buffer)
2579when `scroll-error-top-bottom' is non-nil.
2580
2581*** New option `scroll-error-top-bottom' (see above).
2582
2583*** New scrolling commands `scroll-up-line' and `scroll-down-line'
2584scroll a line instead of full screen.
2585
2586*** New property `scroll-command' should be set on a command's symbol to
2587define it as a scroll command affected by `scroll-preserve-screen-position'.
2588
2589*** If you customize `scroll-conservatively' to a value greater than 100,
2590Emacs will never recenter point in the window when it scrolls due to
2591cursor motion commands or commands that move point (e.f., `M-g M-g').
2592Previously, you needed to use `most-positive-fixnum' as the value of
2593`scroll-conservatively' to achieve the same effect.
2594
2595*** "Aggressive" scrolling now honors the scroll margins.
2596If you customize `scroll-up-aggressively' or
2597`scroll-down-aggressively' and move point off the window, Emacs now
2598scrolls the window so as to avoid positioning point inside the scroll
2599margin.
2600
2601** Basic SELinux support has been added.
2602This requires Emacs to be linked with libselinux at build time.
2603
2604*** Emacs preserves the SELinux file context when backing up.
2605Also, the function `copy-file' has an extra optional argument for
2606preserving SELinux context, and the return value of `backup-buffer'
2607now includes the SELinux context.
2608
2609*** New functions `file-selinux-context' and `set-file-selinux-context'
2610get and set the SELinux context of a file.
2611
2612** Trash changes
2613
2614*** `delete-by-moving-to-trash' now only affects commands that specify
2615trashing. This avoids inadvertently trashing temporary files.
2616
2617*** Calling `delete-file' or `delete-directory' with a prefix argument
2618now forces true deletion, regardless of `delete-by-moving-to-trash'.
2619
2620** File- and directory-local variable changes
2621
2622*** You can stop directory local vars from applying to subdirectories.
2623Add an element (subdirs . nil) to the alist portion of any variables
2624settings to indicate that the section should not apply to
2625subdirectories.
2626
2627*** Directory local variables can apply to some file-less buffers.
2628Affected modes include dired, vc-dir, and log-edit. For example,
2629adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will
2630turn on `whitespace-mode' for *vc-diff* buffers. Modes should call
2631`hack-dir-local-variables-non-file-buffer' to support this.
2632
2633*** Using "mode: MINOR-MODE" to enable a minor mode is deprecated.
2634Instead, use "eval: (minor-mode 1)".
2635
2636*** The variable `inhibit-first-line-modes-regexps' has been renamed
2637to `inhibit-local-variables-regexps'. As the name suggests, it now
2638applies to ALL file local variables, not just -*- lines. The
2639associated `inhibit-first-line-modes-suffixes' has been renamed in the
2640corresponding way.
2641
2642** Window changes
2643
2644*** The `quit-window' command now restores the last buffer displayed
2645in the quitted window.
2646
2647*** Resizing an Emacs frame now preserves proportional window sizes,
2648modulo restrictions like window minimum sizes and fixed-size windows.
2649
2650*** The behavior of `display-buffer' is now customizable in detail.
2651
2652**** New option `display-buffer-base-action' specifies a list of
2653user-determined display "actions" (functions and optional arguments
2654for choosing the displaying window).
2655
2656This takes precedence over the default display action, which is
2657specified by `display-buffer-fallback-action'.
2658
2659**** New option `display-buffer-alist' maps buffer name regexps to
2660display actions, taking precedence over `display-buffer-base-action'.
2661
2662*** New option `window-combination-limit'.
2663The new option `window-combination-limit' allows to return the space
2664obtained for resizing or creating a window more reliably to the window
2665from which such space was obtained.
2666
2667*** New option `window-combination-resize'.
2668The new option `window-combination-resize' allows to split a window that
2669otherwise cannot be split because it's too small by stealing space from
2670other windows in the same combination. Subsequent resizing or deletion
2671of the window will resize all windows in the same combination as well.
2672
2673*** New option `frame-auto-hide-function' lets you choose between
2674iconifying or deleting a frame when burying a buffer in a dedicated
2675frame, or quitting a window showing a buffer in a frame of its own.
2676
2677*** New commands `maximize-window' and `minimize-window'.
2678These maximize and minimize the size of a window within its frame.
2679
2680*** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'.
2681These functions allow to navigate through the live buffers that have
2682been shown in a specific window.
2683
2684** Minibuffer changes
2685
2686*** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'.
2687This is handy for minibuffer-only frames, and is also used for the feature
2688where mouse-1 pops up *Messages*"', which can now easily be changed.
2689
2690*** Minibuffers set `truncate-lines' to nil.
2691If you want to change the value to something else, you could use
2692for example `minibuffer-setup-hook'.
2693
2694** `auto-mode-case-fold' is now enabled by default.
2695
2696** `backup-by-copying-when-mismatch' now defaults to t.
2697
2698** New basic faces `error', `warning', `success'.
2699These are used to highlight text indicating failure, caution or
2700successful operation.
2701
2702** New option `list-colors-sort' defines the color sort order
2703for `list-colors-display'.
2704
2705** The variable `focus-follows-mouse' now always defaults to nil.
2706
2707
2708* Editing Changes in Emacs 24.1
2709
2710** Search changes
2711
2712*** C-y in Isearch is now bound to `isearch-yank-kill', instead of
2713`isearch-yank-line'.
2714
2715*** M-y in Isearch is now bound to `isearch-yank-pop', instead of
2716`isearch-yank-kill'.
2717
2718*** M-s C-e in Isearch is now bound to `isearch-yank-line'.
2719
2720** New commands `count-words-region' and `count-words'.
2721
2722*** M-= is bound to `count-words-region', not `count-lines-region'.
2723The `count-words-region' command, when called interactively, reports
2724the number of lines, words, and characters in the region. It is a
2725superset of the old `count-lines-region', which is now an obsolete
2726alias for it.
2727
2728** The command `just-one-space' (M-SPC), if given a negative argument,
2729also deletes newlines around point.
2730
2731** Deletion changes
2732
2733*** New option `delete-active-region'.
2734If non-nil, [delete] and DEL delete the region if it is active and no
2735prefix argument is given. If set to `kill', those commands kill
2736instead.
2737
2738*** New command `delete-forward-char', bound to [delete].
2739This is meant for interactive use, and obeys `delete-active-region'.
2740The command `delete-char' does not obey `delete-active-region'.
2741
2742*** `delete-backward-char' is now a Lisp function.
2743Apart from obeying `delete-active-region', its behavior is unchanged.
2744However, the byte compiler now warns if it is called from Lisp; Lisp
2745callers should use delete-char with a negative argument instead.
2746
2747*** The option `mouse-region-delete-keys' has been deleted.
2748
2749** Selection changes.
2750
2751The default handling of clipboard and primary selections has been
2752changed to conform with modern X applications. In short, most
2753commands for killing and yanking text now use the clipboard, while
2754mouse commands use the primary selection.
2755
2756In the following, we provide a list of these changes, followed by a
2757list of steps to get the old behavior back if you prefer that.
2758
2759*** `select-active-regions' now defaults to t.
2760Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
2761the kill ring. The selected text is put in the primary selection, if
2762the system possesses a separate primary selection facility (e.g. X).
2763
2764**** `select-active-regions' also accepts a new value, `only'.
2765This means to only set the primary selection for temporarily active
2766regions (usually made by mouse-dragging or shift-selection);
2767"ordinary" active regions, such as those made with C-SPC followed by
2768point motion, do not alter the primary selection.
2769
2770**** `mouse-drag-copy-region' now defaults to nil.
2771
2772*** mouse-2 is now bound to `mouse-yank-primary'.
2773This pastes from the primary selection, ignoring the kill-ring.
2774Previously, mouse-2 was bound to `mouse-yank-at-click'.
2775
2776*** `x-select-enable-clipboard' now defaults to t on all platforms.
2777
2778*** `x-select-enable-primary' now defaults to nil.
2779Thus, commands that kill text or copy it to the kill-ring (such as
2780M-w, C-w, and C-k) also use the clipboard---not the primary selection.
2781
2782**** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
2783exactly equivalent to M-w, C-w, and C-y respectively.
2784
2785**** Note that on MS-Windows, `x-select-enable-clipboard' was already
2786non-nil by default, as Windows does not support the primary selection
2787between applications.
2788
2789*** To return to the previous behavior, do the following:
2790
2791**** Change `select-active-regions' to nil.
2792**** Change `mouse-drag-copy-region' to t.
2793**** Change `x-select-enable-primary' to t (on X only).
2794**** Change `x-select-enable-clipboard' to nil.
2795**** Bind `mouse-yank-at-click' to mouse-2.
2796
2797*** Support for X cut buffers has been removed.
2798
2799*** X clipboard managers are now supported.
2800To inhibit this, change `x-select-enable-clipboard-manager' to nil.
2801
2802** New command `C-x r N' (`rectangle-number-lines') numbers the lines
2803in the current rectangle. With a prefix argument, this prompts for a
2804number to count from and for a format string.
2805
2806** `redisplay-dont-pause' now defaults to t.
2807This makes Emacs feel more responsive to editing commands that arrive
2808at high rate, e.g. if you lean on some key, because stopping redisplay
2809in the middle (when this variable is nil) forces more expensive
2810updates later on, and Emacs appears to be unable to keep up.
2811
2812** The behavior of <TAB> for active regions in Text mode has changed.
2813In Text and related modes, typing <TAB> (`indent-for-tab-command')
2814when the region is active causes Emacs to indent all the lines in the
2815region, aligning them with the line previous to the first line in the
2816region (or with the left margin if there is no previous line).
2817
2818** When `occur' is called with a prefix argument, matching strings are
2819collected into the `*Occur*' buffer without line numbers. If there
2820are parenthesized subexpressions in the specified regexp, `occur'
2821reads replacement text that may contain \\& and \\N whose convention
2822follows `replace-match'.
2823
2824
2825* Changes in Specialized Modes and Packages in Emacs 24.1
2826
2827** Archive Mode has basic support for browsing and updating 7z archives.
2828
2829** BibTeX mode
2830
2831*** BibTeX mode now supports biblatex.
2832Use the variable `bibtex-dialect' to select different BibTeX dialects.
2833`bibtex-entry-field-alist' is now an obsolete alias for
2834`bibtex-BibTeX-entry-alist'.
2835
2836*** New command `bibtex-search-entries', bound to C-c C-a.
2837
2838*** New `bibtex-entry-format' option `sort-fields', disabled by default.
2839
2840*** New variable `bibtex-search-entry-globally'.
2841
2842** Browse-url
2843
2844*** New option `browse-url-mailto-function' specifies how to handle "mailto:"s.
2845
2846*** The default browser used by the package is now the "xdg-open" program,
2847on platforms that support it. This calls your desktop's preferred browser.
2848
2849** Calc
2850
2851*** Support for musical notes.
2852
2853*** Support for logarithmic units.
2854
2855*** No longer uses the tex prefix for TeX specific unit names when
2856using TeX or LaTeX mode.
2857
2858*** New option to highlight selections using faces.
2859
2860*** `calc-histogram' has the option of using a vector to determine the bins.
2861
2862*** New "O" option prefix.
2863
2864*** Use the "O" prefix to "d r" (`calc-radix') to turn on twos-complement mode.
2865
2866** Calendar, Diary, and Appt
2867
2868*** Diary entries can contain non-printing "comments".
2869See the variable `diary-comment-start'.
2870
2871*** Appointments can specify their individual warning times.
2872See the variable `appt-warning-time-regexp'.
2873
2874*** The function specified by `appt-disp-window-function' may be passed
2875lists of arguments if multiple appointments are due at similar times.
2876If you are using a custom function for this, you should update it.
2877
2878*** New function `diary-hebrew-birthday'.
2879
2880*** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array'
2881may no longer be nil, but must all be strings.
2882
2883*** The obsolete (since Emacs 22.1) method of enabling the appt
2884package by adding `appt-make-list' to `diary-hook' has been removed.
2885Use `appt-activate' instead.
2886
2887*** Some appt variables (obsolete since Emacs 22.1) have been removed:
2888appt-issue-message (use the function appt-activate)
2889appt-visible/appt-msg-window (use the variable appt-display-format)
2890
2891*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
2892view-diary-entries, list-diary-entries, show-all-diary-entries
2893
2894** CC Mode
2895
2896*** New feature to "guess" the style in an existing buffer.
2897The main entry point is M-x c-guess.
2898
2899*** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang).
2900
2901*** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes.
2902Thus C-M-a will, by default, go to the beginning of the immediate function,
2903not the top level.
2904
2905*** "Macros with semicolons" can be registered for correct indentation.
2906Where such a macro ends a line (no semicolon) the next statement is no longer
2907parsed as a statement continuation.
2908
2909** Comint and modes derived from it use the standard completion code.
2910
2911** Compilation mode
2912
2913*** Compilation mode can be used without Font Lock mode.
2914`compilation-parse-errors-function' is now obsolete.
2915
2916*** New variable `compilation-filter-start', which is bound while
2917`compilation-filter-hook' runs. It records the start position of the
2918text inserted by `compilation-filter'.
2919
2920*** `compilation-error-screen-columns' and `compilation-first-column'
2921are obeyed in the editing buffer. So programming language modes can
2922set them, whereas previously only the value in the *Compilation*
2923buffer was used.
2924
2925** Customize
2926
2927*** Customize buffers now contain a search field.
2928The search is performed using `customize-apropos'.
2929To turn off the search field, set `custom-search-field' to nil.
2930
2931*** Options in customize group buffers start out hidden if not customized.
2932Use the arrow to the left of the option name to toggle visibility.
2933
2934*** custom-buffer-sort-alphabetically now defaults to t.
2935
2936*** The color widget now has a "Choose" button, which allows you to
2937choose a color via `list-colors-display'.
2938
2939** D-Bus
2940
2941*** It is now possible to access buses other than the default system
2942or session bus.
2943
2944*** The `dbus-register-method' and `dbus-register-property' functions
2945optionally do not register names.
2946
2947*** The new function `dbus-register-service' registers a known service
2948name on a D-Bus without also registering a property or a method.
2949
2950** Dired-x
2951
2952*** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'),
2953if called with a prefix argument, read a file name from the minibuffer
2954instead of using the current buffer.
2955
2956*** The "dired local variables" feature of Dired-x is obsolete.
2957The standard directory local variables feature replaces it.
2958
2959** ERC changes
2960
2961*** New options `erc-autojoin-timing' and `erc-autojoin-delay',
2962controlling attempts to autojoin a channel.
2963
2964*** New variable `erc-coding-system-precedence': If we use `undecided'
2965as the server coding system, this variable will then be consulted.
2966The default is to decode strings that can be decoded as utf-8 as
2967utf-8, and do the normal `undecided' decoding for the rest.
2968
2969** Eshell changes
2970
2971*** The default value of `eshell-directory-name' has changed
2972to be an "eshell" directory in `user-emacs-directory'.
2973The old "~/.eshell/" directory is still used if it exists, though.
2974
2975** gdb-mi
2976
2977*** The M-x gdb command now uses the GDB Machine Interface protocol.
2978It now supports multithread non-stop debugging and simultaneous
2979debugging of several threads.
2980
2981** Image mode
2982
2983*** RET (`image-toggle-animation') toggles animation, if applicable.
2984Animation plays once, unless the option `image-animate-loop' is non-nil.
2985
2986** Info
2987
2988*** New command M-x info-display-manual displays a named Info manual.
2989If that manual is already visited in some Info buffer, it displays
2990that buffer. (This is handy if you have many manuals in many *info*
2991buffers, and don't remember the name of the buffer visiting the manual
2992you want to consult.) Otherwise, it loads and displays the manual.
2993
2994*** `e' is now bound to `end-of-buffer' rather than to `Info-edit'.
2995This is for compatibility with the stand-alone Info reader program,
2996and also because `Info-edit' is a rarely used command that is disabled
2997by default.
2998
2999** Mail mode changes (not Message mode)
3000
3001*** New command M-x mail-add-attachment for adding MIME attachments
3002
3003*** The command M-x mail-attach-file was renamed to M-x mail-insert-file.
3004(Its name is misleading, since it has nothing to do with MIME
3005attachments.) The old name is now an obsolete alias to the new name.
3006
3007** MH-E has been updated to MH-E version 8.3.1.
3008See MH-E-NEWS for details.
3009
3010** Modula-2 mode provides auto-indentation.
3011
3012** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
3013
3014** nXML mode no longer binds C-RET to `nxml-complete'.
3015Completion is now performed via `completion-at-point', bound to C-M-i
3016or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the
3017default), this performs tag completion.
3018
3019** Org mode has been updated to version 7.8.09.
3020See ORG-NEWS for details.
3021
3022** Prolog mode has been completely revamped, with lots of additional
3023functionality such as more intelligent indentation, electricity,
3024support for more variants, including Mercury, and a lot more.
3025
3026** Rmail
3027
3028*** The command `rmail-epa-decrypt' decrypts OpenPGP data
3029in the Rmail incoming message.
3030
3031*** The variable `rmail-message-filter' no longer has any effect.
3032This change was made in Emacs 23.1 but was not advertised at the time.
3033Try using `rmail-show-message-hook' instead.
3034
3035** Shell mode
3036
3037*** M-x shell prompts for the shell path name if the default directory
3038is a remote file name and neither the environment variable $ESHELL nor
3039the variable `explicit-shell-file-name' is set.
3040
3041*** TAB is now bound to the standard `completion-at-point' command,
3042which now implements the pcomplete rules for shell command completion.
3043
3044** SMTPmail
3045
3046*** SMTPmail now uses encrypted connections (via STARTTLS) by default
3047if the mail server supports them. This uses either built-in GnuTLS
3048support, or the starttls.el library. Customize `smtpmail-stream-type'
3049to change this.
3050
3051*** The variable `smtpmail-auth-credentials' has been removed.
3052By default, the information is now stored in the file ~/.authinfo.
3053This was the default value of smtpmail-auth-credentials. If you had
3054customized smtpmail-auth-credentials to a list of user names and
3055passwords, those settings are not used. During your first connection
3056to the smtp server, Emacs will prompt for the user name and password,
3057and offer to save them to ~/.authinfo. Or you can manually copy the
3058credentials to ~/.authinfo. For example, if you had
3059
3060 (setq smtpmail-auth-credentials
3061 '(("mail.example.org" 25 "jim" "s!cret")))
3062
3063then the equivalent line in ~/.authinfo would be
3064
3065 machine mail.example.org port 25 login jim password s!cret
3066
3067See the auth-source manual for more information, e.g. on encrypting
3068the credentials file.
3069
3070*** The variable `smtpmail-starttls-credentials' has been removed.
3071If you had that set, you need to put
3072
3073 machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert"
3074
3075in your ~/.authinfo file instead.
3076
3077*** SMTPmail defaults to using the address in the From: header as the
3078SMTP MAIL FROM envelope. To override this, set `mail-envelope-from'
3079to the address you wish to use instead.
3080
3081** SQL mode
3082
3083*** New options `sql-port', `sql-connection-alist', `sql-send-terminator',
3084and `sql-oracle-scan-on'.
3085
3086*** New options controlling prompting for login parameters.
3087Each supported product has a custom variable `sql-*-login-params',
3088which is a list of the parameters to be prompted for before a
3089connection is established.
3090
3091*** The command `sql-product-interactive' now takes a prefix argument,
3092which causes it to prompt for an SQL product.
3093
3094*** Product-specific SQL interactive commands now take prefix arguments.
3095These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.),
3096given a prefix argument, prompt for a name for the SQL interactive
3097buffer. This reduces the need for calling `sql-rename-buffer'.
3098
3099*** SQL interactive modes suppress command continuation prompts, and
3100replace tabs with spaces. The first change impacts multiple line SQL
3101statements entered with C-j between each line, statements yanked into
3102the buffer and statements sent with `sql-send-*' functions. The
3103second prevents the MySQL and Postgres interpreters from listing
3104object name completions when sent text via `sql-send-*' functions.
3105
3106*** New command `sql-connect' starts a predefined SQLi session,
3107using the login parameters from `sql-connection-alist'.
3108
3109*** New "Save Connection" menu item in SQLi buffers.
3110This gathers the login params specified for the SQLi session, if it
3111was not started by a connection, and saves them as a new connection.
3112
3113*** New commands for listing database objects and details:
3114sql-list-all and sql-list-table.
3115
3116*** An API for manipulating SQL product definitions has been added.
3117
3118** TeX modes
3119
3120*** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
3121
3122** Tramp
3123
3124*** New inline access method "ksu" (kerberized su).
3125
3126*** The following access methods are discontinued: "ssh1_old",
3127"ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish".
3128
3129*** The user option `remote-file-name-inhibit-cache' controls whether
3130remote file attributes are cached for better performance.
3131
3132*** The option `ange-ftp-binary-file-name-regexp' has changed its
3133default value to "".
3134
3135*** Handlers for `file-selinux-context' and `set-file-selinux-context'
3136for remote machines which support SELinux.
3137
3138** New function `url-queue-retrieve', which behaves like url-retrieve,
3139but with limits (`url-queue-parallel-processes', `url-queue-timeout') on
3140the degree of parallelism.
3141
3142** VC and related modes
3143
3144*** Support for pulling on distributed version control systems.
3145The command C-x v + (`vc-pull') runs a "pull" operation, if it is
3146supported (currently with Bzr, Git, and Mercurial), to update the
3147current branch and working tree. A prefix argument means to prompt
3148the user for specifics, e.g. a pull location.
3149
3150*** `vc-update' is now an alias for `vc-pull'.
3151
3152*** Support for merging on distributed version control systems.
3153The command C-x v m (`vc-merge') now runs a "merge" operation, if it
3154is supported (currently with Bzr, Git, and Mercurial), to merge
3155changes from another branch into the current one. It prompts for
3156specifics, e.g. a merge source.
3157
3158*** New option `vc-revert-show-diff' controls whether `vc-revert'
3159shows a diff while querying the user. It defaults to t.
3160
3161*** Log entries in some Log View buffers can be toggled to display a
3162longer description by typing RET (log-view-toggle-entry-display).
3163This is currently supported for Bzr, Git, and Mercurial (to support
3164another backend, define a `log-view-expanded-log-entry-function').
3165In the Log View buffers made by C-x v L (`vc-print-root-log'), you can
3166use this to display the full log entry for the revision at point.
3167
3168*** New command `vc-ediff' allows visual comparison of two revisions
3169of a file similar to `vc-diff', but using ediff backend.
3170
3171*** The option `vc-initial-comment' was removed in Emacs 23.2, but
3172this was not advertised at the time.
3173
3174*** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'.
3175Since Emacs 23, it has done the same thing as `toggle-read-only', but
3176this was not advertised at the time.
3177
3178** Obsolete modes
3179
3180*** abbrevlist.el
3181
3182*** erc-hecomplete.el (use erc-pcomplete.el instead)
3183
3184*** partial-completion-mode (complete.el) is obsolete.
3185You can get a comparable behavior with:
3186(setq completion-styles '(partial-completion initials))
3187(setq completion-pcm-complete-word-inserts-delimiters t)
3188
3189*** pc-mode.el is obsolete (CUA mode is much more comprehensive).
3190
3191*** pgg is obsolete (use EasyPG instead).
3192
3193*** sregex.el is obsolete, since rx.el is a strict superset.
3194
3195*** s-region.el and pc-select.el are obsolete.
3196They are superseded by shift-select-mode, enabled by default since 23.1.
3197
3198*** vc-mcvs.el is obsolete (for lack of a maintainer).
3199
3200** Miscellaneous
3201
3202*** The Landmark game is now invoked with `landmark', not `lm'.
3203Its functions and variables have been similarly renamed.
3204
3205*** In `ido-file-completion-map', C-v is no longer bound to `ido-toggle-vc'.
3206(This interfered with cua-mode.)
3207
3208*** f90.el has some support for Fortran 2008 syntax.
3209
3210*** `copyright-fix-years' can optionally convert consecutive years to ranges.
3211
3212*** New command `nato-region' converts text to NATO phonetic alphabet.
3213
3214
3215* New Modes and Packages in Emacs 24.1
3216
3217** Occur Edit mode applies edits made in *Occur* buffers to the
3218original buffers. It is bound to "e" in Occur mode.
3219
3220** New global minor mode electric-pair-mode.
3221When enabled, typing an open parenthesis automatically inserts the
3222matching closing one.
3223
3224** New global minor mode electric-indent-mode.
3225When enabled, typing certain characters triggers reindentation.
3226Major modes wishing to use this can set electric-indent-chars or
3227electric-indent-functions.
3228
3229** New global minor mode electric-layout-mode.
3230When enabled, typing certain characters automatically inserts newlines.
3231Major modes wishing to use this can set electric-layout-rules.
3232
3233** tabulated-list.el provides a generic major mode for tabulated data,
3234from which other modes can be derived.
3235
3236** pcase.el provides the ML-style pattern matching macro `pcase'.
3237
3238** secrets.el is an implementation of the Secret Service API, an
3239interface to password managers like GNOME Keyring or KDE Wallet. The
3240Secret Service API requires D-Bus for communication. The command
3241`secrets-show-secrets' offers a buffer with a visualization of the
3242secrets.
3243
3244** notifications.el provides an implementation of the Desktop
3245Notifications API. It requires D-Bus for communication.
3246
3247** soap-client.el supports access to SOAP web services from Emacs.
3248soap-inspect.el is an interactive inspector for SOAP WSDL structures.
3249
3250** New generic mode, xmodmap-generic-mode, for xmodmap files.
3251
3252** New emacs-lock.el package.
3253The previous version has been moved to obsolete/old-emacs-lock.el.
3254Now, there is a proper minor mode `emacs-lock-mode'. Protection
3255against exiting Emacs and killing the buffer can be set separately.
3256The mechanism for automatically turning off protection for buffers
3257with dead inferior processes has been generalized.
3258
3259
3260* Incompatible Lisp Changes in Emacs 24.1
3261
3262** Passing a nil argument to a minor mode function call now ENABLES
3263the minor mode unconditionally. This is so that you can write e.g.
3264
3265 (add-hook 'text-mode-hook 'foo-mode)
3266
3267to enable foo-mode in Text mode buffers, removing the need for
3268`turn-on-foo-mode' style functions. This affects all mode commands
3269defined by `define-minor-mode'. If called interactively, the mode
3270command still toggles the minor mode.
3271
3272** The return value of `backup-buffer' has changed.
3273It is now a list of three elements, where the second element is a list
3274describing the original file's SELinux context. If Emacs or the
3275system lacks SELinux support, the context list is (nil nil nil nil).
3276See "Basic SELinux support" above, under "Changes in Emacs 24.1".
3277
3278** `char-direction-table' and the `char-direction' function were deleted.
3279They were buggy and inferior to the new support of bidirectional
3280editing introduced in Emacs 24. If you need the bidirectional
3281properties of a character, use `get-char-code-property' with the last
3282argument `bidi-class'.
3283
3284** `copy-directory' now copies the source directory as a subdirectory
3285of the target directory, if the latter is an existing directory. The
3286new optional arg COPY-CONTENTS, if non-nil, makes the function copy
3287the contents directly into a pre-existing target directory.
3288
3289** For mouse click input events in the text area, the Y pixel
3290coordinate in the POSITION list now counts from the top of the text
3291area, excluding any header line. Previously, it counted from the top
3292of the header line.
3293
3294** Support for "old-style" backquotes, obsolete for 10+ years, has
3295been further reduced. Now a backquote not followed by a space is
3296always treated as a "new-style" backquote. Please remove all
3297"old-style" backquotes from your code. If your code uses backquotes
3298as documented in the Elisp manual, and compiles without warning, then
3299you have nothing to do in this regard. Code not following the
3300appropriate conventions may fail to compile.
3301
3302The most common cause of trouble seems to be an old-style backquote
3303followed by a newline. Another cause of trouble is vector notation
3304for key sequence notation: instead of [(control ,)] and [(control ')],
3305you should write [(control ?,)] and [(control ?')], which will work in
3306older Emacsen too.
3307
3308** The macro `eval-at-startup' was removed in Emacs 23.2, but this
3309was not advertised at the time. The function `custom-initialize-delay'
3310replaced all known uses.
3311
3312** `view-buffer' now treats special mode-class in the same way that
3313`view-file' has since Emacs 22 (i.e. it won't enable View mode if the
3314major mode is special).
3315
3316** Menu and tool bar changes
3317
3318*** During startup, Emacs no longer adds entries for `menu-bar-lines'
3319and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'.
3320With these alist entries omitted, `make-frame' checks the value of the
3321variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create
3322a menu-bar or tool-bar, respectively. If the alist entries are added,
3323they override the value of `menu-bar-mode'/`tool-bar-mode'.
3324
3325*** The menu bar bindings's caches are not used any more.
3326Use (where-is-internal <def> nil t) instead.
3327
3328** Regions created by mouse dragging are now normal active regions,
3329similar to those created by shift-selection (see Selection changes
3330above). In previous Emacs versions, these regions were delineated by
3331`mouse-drag-overlay'; that variable has been removed.
3332
3333** The fourth argument of `filter-buffer-substring' has been removed.
3334If you want to remove text properties from the final result, simply
3335pass the result through substring-no-properties.
3336
3337** cl.el no longer provides `cl-19'.
3338
3339** The following obsolete functions and aliases have been removed
3340(the appropriate new function is given in parentheses; "not needed"
3341means you can just remove all calls to the function in question):
3342
3343*** `comint-kill-output' (`comint-delete-output')
3344*** `decompose-composite-char' (`char-to-string')
3345*** `outline-visible' (`outline-invisible-p')
3346*** `internal-find-face' (`facep')
3347*** `internal-get-face' (`facep and check-face')
3348*** `frame-update-faces' (not needed)
3349*** `frame-update-face-colors' (`frame-set-background-mode')
3350*** `x-frob-font-weight' and `x-frob-font-slant' (`make-face-*' functions)
3351*** `x-make-font-bold' and `x-make-font-demibold' (`make-face-bold')
3352*** `x-make-font-italic' and `x-make-font-oblique' (`make-face-italic')
3353*** `x-make-font-bold-italic' (`make-face-bold-italic')
3354*** `x-make-font-unbold' (`make-face-unbold')
3355*** `x-make-font-unitalic' (`make-face-unitalic')
3356*** `mldrag-drag-mode-line' (`mouse-drag-mode-line')
3357*** `mldrag-drag-vertical-line' (`mouse-drag-vertical-line')
3358*** `iswitchb-default-keybindings' (`iswitchb-mode')
3359*** `char-bytes' (== 1)
3360*** `isearch-return-char' (`isearch-printing-char')
3361*** `make-local-hook' (not needed)
3362*** `set-screen-height' (`set-frame-height')
3363*** `set-screen-width' (`set-frame-width')
3364
3365** The following obsolete variables and varaliases have been removed
3366(the appropriate new variable is given in parentheses):
3367
3368*** `checkdoc-minor-keymap' (`checkdoc-minor-mode-map')
3369*** `vc-header-alist' (`vc-BACKEND-header')
3370*** `directory-sep-char' (== ?/)
3371*** `font-lock-defaults-alist' (`font-lock-defaults')
3372*** `e' (`float-e').
3373
3374** The following obsolete files were removed:
3375sc.el, x-menu.el, rnews.el, rnewspost.el
3376
3377** The format of the finder-inf.el file has changed, since the Finder
3378mechanism is now based on the package system. The variable
3379`finder-package-info' is replaced by `package--builtins' and
3380`finder-keywords-hash'.
3381
3382** When generating autoloads, `update-directory-autoloads' no longer
3383assumes every inspected file is in your `load-path'. It instead
3384generates relative names according to the current `load-path'.
3385
3386
3387* Lisp Changes in Emacs 24.1
3388
3389** Code can now use lexical scoping by default instead of dynamic scoping.
3390The `lexical-binding' variable enables lexical scoping for local
3391variables. It is typically set via a file-local variable in the first
3392line of the file, in which case it applies to all the code in that
3393file.
3394
3395*** `eval' takes a new optional argument `lexical' to choose the new lexical
3396binding instead of the old dynamic binding mode.
3397
3398*** Lexically scoped interpreted functions are represented with a new form
3399of function value which looks like (closure ENV ARGS &rest BODY).
3400
3401*** New macro `letrec' to define recursive local functions.
3402
3403*** `defvar' and `defconst' now mark the variable as special (dynamic).
3404So do `defcustom' and other forms that call `defvar' as a subroutine.
3405
3406*** New function `special-variable-p' to check whether a variable is
3407declared as dynamically bound.
3408
3409*** The form ((lambda ...) ...) is deprecated.
3410
3411** An Emacs Lisp testing tool is now included.
3412Emacs Lisp developers can use this tool to write automated tests for
3413their code. See the ERT info manual for details.
3414
3415** Changes for bidirectional display and editing
3416
3417*** New function `current-bidi-paragraph-direction'.
3418This returns the base direction of the paragraph at point.
3419
3420*** New function `bidi-string-mark-left-to-right'.
3421Given a string containing characters from right-to-left scripts, this
3422function returns another string which can be safely inserted into a
3423buffer, such that any following text will be always displayed to the
3424right of that string. (This works by appending an invisible Unicode
3425"LEFT-TO-RIGHT MARK" character if the argument string might need it.)
3426
3427This is useful when the buffer has overall left-to-right paragraph
3428direction and you need to insert a string whose contents are not known
3429in advance, without disrupting the layout of the line.
3430
3431** Window changes
3432
3433*** Window tree functions are accessible in Elisp.
3434Functions are provided to return the parent, siblings or child windows
3435of any window including internal windows (windows not associated with a
3436buffer) in the window tree.
3437
3438**** New function `window-valid-p' gives non-nil for live and internal
3439windows.
3440
3441**** Window manipulation can deal with internal windows.
3442Many window handling functions like `split-window', `delete-window', or
3443`delete-other-windows' as well as the window resizing functions can now
3444act on any window including internal ones.
3445
3446*** window-total-height/-width vs window-body-height/-width.
3447The function `window-height' has been renamed to `window-total-height'
3448and `window-width' has been renamed to `window-body-width'. The old
3449names are provided as aliases. Two new functions `window-total-width'
3450and `window-body-height' are provided.
3451
3452*** Window parameters specific to window handling functions.
3453For each window you can specify a parameter to override the default
3454behavior of a number of functions like `split-window', `delete-window'
3455and `delete-other-windows'. The variable `ignore-window-parameters'
3456allows to ignore processing such parameters.
3457
3458*** New semantics of third argument of `split-window'.
3459The third argument of `split-window' has been renamed to SIDE and can be
3460set to any of the values 'below, 'right, 'above, or 'left to make the
3461new window appear on the corresponding side of the window that shall be
3462split. Any other value of SIDE will cause `split-window' to split the
3463window into two side-by-side windows as before.
3464
3465*** Window resizing functions.
3466A new standard function for resizing windows called `window-resize' has
3467been introduced. This and all other functions for resizing windows no
3468longer delete any windows when they become too small.
3469
3470*** Deleting the selected window now selects the most recently selected
3471live window on that frame instead.
3472
3473*** `adjust-window-trailing-edge' adjustments.
3474`adjust-window-trailing-edge' can now deal with fixed-size windows and
3475is able to resize other windows if a window adjacent to the trailing
3476edge cannot be shrunk any more. This makes its behavior more similar to
3477that of Emacs 21 without compromising, however, its inability to delete
3478windows which was introduced in Emacs 22.
3479
3480*** Window-local buffer lists.
3481Windows now have local buffer lists. This means that removing a buffer
3482from display in a window will preferably show the buffer previously
3483shown in that window with its previous window-start and window-point
3484positions. This also means that the same buffer may be automatically
3485shown twice even if it already appears in another window.
3486
3487*** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW,
3488which if non-nil requires the buffer to be displayed in the currently
3489selected window, signaling an error otherwise. If nil, another window
3490can be used, e.g. if the selected one is strongly dedicated.
3491
3492*** `split-window-vertically' and `split-window-horizontally' renamed
3493to `split-window-below' and `split-window-right' respectively.
3494The old names are kept as aliases.
3495
3496*** Display actions
3497
3498**** The second arg to `display-buffer' and `pop-to-buffer' is now
3499named ACTION, and takes a display action of the same form as
3500`display-buffer-base-action' (see Changes, above). A non-nil,
3501non-list value is treated specially, as the old meaning.
3502
3503**** New variable `display-buffer-overriding-action'.
3504
3505**** The procedure of `display-buffer' etc. to choose a window is
3506determined by combining `display-buffer-overriding-action',
3507`display-buffer-alist', the ACTION arg, `display-buffer-base-action',
3508and `display-buffer-fallback-action'. The second and fourth of these
3509are user-customizable variables.
3510
3511See the docstring of `display-buffer' for details.
3512
3513*** New functions `window-state-get' and `window-state-put'.
3514These functions allow to save and restore the state of an arbitrary
3515frame or window as an Elisp object.
3516
3517** Completion
3518
3519*** New variable `completion-extra-properties' used to specify extra
3520properties of the current completion:
3521- :annotate-function, same as the old completion-annotate-function.
3522- :exit-function, function to call after completion took place.
3523
3524*** Functions on `completion-at-point-functions' can return any of the
3525properties valid for `completion-extra-properties'.
3526
3527*** `completion-annotate-function' is obsolete.
3528
3529*** New `metadata' method for completion tables. The metadata thus returned
3530can specify various details of the data returned by `all-completions':
3531- `category' is the kind of objects returned (e.g., `buffer', `file', ...),
3532 used to select a style in completion-category-overrides.
3533- `annotation-function' to add annotations in *Completions*.
3534- `display-sort-function' to specify how to sort entries in *Completions*.
3535- `cycle-sort-function' to specify how to sort entries when cycling.
3536
3537*** `minibuffer-local-filename-must-match-map' is not used any more.
3538Instead, the bindings in `minibuffer-local-filename-completion-map'
3539are combined with `minibuffer-local-must-match-map'.
3540
3541*** New variable `completing-read-function' allows overriding the
3542behavior of `completing-read'.
3543
3544** `glyphless-char-display' can now distinguish between graphical and
3545text terminal display, via a char-table entry that is a cons cell.
3546
3547** `pre-command-hook'/`post-command-hook' are not reset to nil on error.
3548Instead, the offending function is removed.
3549
3550** New hook types
3551
3552*** New function `run-hook-wrapped' for running an abnormal hook by
3553passing the hook functions as arguments to a "wrapping" function.
3554Like `run-hook-with-args-until-success', it stops at the first
3555non-nil return value.
3556
3557*** New macro `with-wrapper-hook' for running an abnormal hook as a
3558set of "wrapping" filters, similar to around advice.
3559(A version of this macro was actually added in Emacs 23.2 but was not
3560advertised at the time.)
3561
3562** Debugger changes
3563
3564*** New macro `condition-case-unless-debug' (this was actually added in
3565Emacs 23.1 as condition-case-no-debug, but not advertised)
3566
3567*** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised.
3568
3569*** Variable `stack-trace-on-error' removed.
3570
3571*** The debugger can now "continue" from an error, which means it will
3572jump to the error handler as if the debugger had not been invoked
3573instead of jumping all the way to the top-level.
3574
3575*** Set `debug-on-event' to enter the debugger on events like SIGUSR1.
3576This can be useful when `inhibit-quit' is set.
3577
3578** The new function `server-eval-at' allows evaluation of Lisp forms on
3579named Emacs server instances.
3580
3581** `call-process' and `call-process-region' allow a `(:file "file")' spec
3582to redirect STDOUT to a file.
3583
3584** The function `format-time-string' now supports the %N directive,
3585for higher-resolution time stamps.
3586
3587** New input reading functions
3588
3589*** New function `read-char-choice' reads a restricted set of
3590characters, discarding any inputs not inside the set.
3591
3592*** The command `read-color' now requires a match for a color name
3593or RGB triplet, instead of signaling an error if the user provides
3594invalid input.
3595
3596**** `facemenu-read-color' is now an alias for `read-color'.
3597
3598** `image-library-alist' is renamed to `dynamic-library-alist'.
3599The variable is now used to load all kind of supported dynamic libraries,
3600not just image libraries. The previous name is still available as an
3601obsolete alias.
3602
3603** Syntax parsing changes
3604
3605*** New variable `syntax-propertize-function'.
3606This replaces `font-lock-syntactic-keywords' which is now obsolete.
3607This allows syntax-table properties to be set independently from font-lock:
3608just call syntax-propertize to make sure the text is propertized.
3609Together with this new variable come a new hook
3610syntax-propertize-extend-region-functions, as well as two helper functions:
3611syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
3612as-is; and syntax-propertize-rules which provides a new way to specify
3613syntactic rules.
3614
3615*** Syntax tables support a new "comment style c" additionally to style b.
3616
3617** New hook `post-self-insert-hook', run after `self-insert-command'.
3618
3619** frame-local variables cannot be let-bound any more.
3620
3621** Major and minor mode changes
3622
3623*** `set-auto-mode' now respects mode: local variables at the end of files,
3624as well as those in the -*- line.
3625
3626*** `prog-mode' is a new major mode from which programming modes
3627should be derived.
3628
3629**** `prog-mode-hook' can be used to enable features for programming
3630modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable
3631on-the-fly spell checking for comments and strings.
3632
3633*** New hook `change-major-mode-after-body-hook', run by
3634`run-mode-hooks' just before any other mode hooks.
3635
3636*** Enabled globalized minor modes can be disabled in specific major modes.
3637If the global mode is global-FOO-mode, then run (FOO-mode -1) in the
3638major mode's hook, where FOO-mode toggles the mode on a per-buffer basis.
3639
3640*** `define-minor-mode' accepts new keywords :variable, :after-hook.
3641
3642** File-handling changes
3643
3644*** `delete-file' and `delete-directory' now accept optional arg TRASH.
3645Trashing is performed if TRASH and `delete-by-moving-to-trash' are
3646both non-nil. Interactively, TRASH defaults to t, unless a prefix
3647argument is supplied (see Trash changes, above).
3648
3649*** New file predicates: `file-equal-p', `file-in-directory-p'.
3650
3651** Tool-bars can display separators.
3652Tool-bar separators are handled like menu separators in menu-bar maps,
3653i.e. via menu entries of the form `(menu-item "--")'.
3654
3655** Image API
3656
3657*** Animated images support (currently animated gifs only).
3658
3659**** `image-animated-p' returns non-nil if an image can be animated.
3660
3661**** `image-animate' animates a supplied image spec.
3662
3663**** `image-animate-timer' returns the timer object for an image that
3664is being animated.
3665
3666*** `image-extension-data' has been renamed to `image-metadata'.
3667The old name is an obsolete alias to the new one.
3668
3669*** Image mode can view any image type that ImageMagick supports.
3670This requires Emacs to be built with ImageMagick support.
3671
3672**** New function `imagemagick-types', defined if ImageMagick support
3673is enabled, returns a list of image file extensions that your
3674ImageMagick installation supports.
3675
3676**** New function `imagemagick-register-types' enables ImageMagick
3677image types in Image mode and in `create-image' and other helper
3678functions.
3679
3680**** New option `imagemagick-types-inhibit' excludes certain
3681ImageMagick image types from `imagemagick-register-types'.
3682
3683**** With ImageMagick support, there are extra Image mode commands to
3684resize and rotate images: `image-transform-fit-to-height',
3685`image-transform-fit-to-width', `image-transform-set-rotation', and
3686`image-transform-set-scale'.
3687
3688** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and
3689passes it to the mail user agent function. This argument specifies an
3690action for returning to the caller after finishing with the mail. For
3691example, this is used by Rmail to optionally delete a mail window.
3692
3693** XML and HTML parsing
3694If Emacs is compiled with libxml2 support, there are two new
3695functions: `libxml-parse-html-region' (which parses "real world" HTML)
3696and `libxml-parse-xml-region' (which parses XML). Both return an
3697Emacs Lisp parse tree.
3698
3699** Networking and encryption changes
3700
3701*** `open-network-stream' can now be used to open an encrypted stream.
3702It now accepts an optional `:type' parameter for initiating a TLS
3703connection, directly or via STARTTLS. To do STARTTLS, additional
3704parameters (`:end-of-command', `:success', `:capabilities-command')
3705must also be supplied.
3706
3707*** New library gnutls.el.
3708The new function `gnutls-available-p' returns non-nil if Emacs is
3709built with GnuTLS support. The main entry points are
3710`open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use
3711these functions through `open-network-stream', because that can
3712upgrade connections through STARTTLS opportunistically or use plain
3713SSL, depending on your needs. For debugging, set `gnutls-log-level'
3714greater than 0.
3715
3716*** New primitive `secure-hash' that supports many secure hash algorithms:
3717md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library
3718sha1.el has been removed. The `sha1' feature is provided by default.
3719
3720** Isearch
3721
3722*** New hook `isearch-update-post-hook' that runs in `isearch-update'.
3723
3724** Progress reporters can now "spin".
3725The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
3726now be nil, or omitted. This makes a "non-numeric" reporter. Each
3727time you call `progress-reporter-update' on that progress reporter,
3728with a nil or omitted VALUE argument, the reporter message is
3729displayed with a "spinning bar".
3730
3731** New variable `revert-buffer-in-progress-p' is true while a buffer is
3732being reverted, even if the buffer has a local `revert-buffer-function'.
3733
3734** New variables `delayed-warnings-list' and `delayed-warnings-hook'.
3735If delayed-warnings-list is non-nil, the command loop calls
3736`delayed-warnings-hook' after `post-command-hook'. At present, this
3737is only used by Emacs on some platforms to display warnings during
3738startup, which might otherwise not be noticed. This uses the
3739functions `display-delayed-warnings' and `collapse-delayed-warnings'.
3740
3741** rx.el has a new `group-n' construct for explicitly numbered groups.
3742
3743** New function `make-composed-keymap' that constructs a new keymap
3744from multiple input maps. You can use this to make a keymap that
3745inherits from multiple maps, eg:
3746 (set-keymap-parent newmap (make-composed-keymap othermap parent))
3747
3748** New function `string-prefix-p'.
3749(This was actually added in Emacs 23.2 but was not advertised at the time.)
3750
3751** New reader macro ## that stands for the empty symbol.
3752This means that the empty symbol can now be read back. Also, #: by itself
3753(when not immediately followed by a possible symbol character) stands for
3754an empty uninterned symbol.
3755
3756** New math functions `isnan', `copysign', `frexp', `ldexp'.
3757
3758** The following functions and variables are obsolete:
3759
3760*** `tooltip-use-echo-area' is obsolete.
3761Rather than setting this to t, disable Tooltip mode instead.
3762
3763*** buffer-substring-filters is obsolete.
3764Use `filter-buffer-substring-functions' instead.
3765
3766*** `byte-compile-disable-print-circle' is obsolete.
3767
3768*** `deferred-action-list' and `deferred-action-function' are obsolete.
3769Use `post-command-hook' instead.
3770
3771*** `font-lock-maximum-size' is obsolete.
3772
3773
3774* Changes in Emacs 24.1 on Non-Free Operating Systems
3775
3776** On MS Windows, Emacs warns when using the obsolete init file _emacs,
3777and also when HOME is set to C:\ by default.
3778
3779** New configure.bat options
3780
3781*** --enable-checking builds Emacs with extra runtime checks.
3782
3783*** --distfiles specifies files to be included in binary distribution.
3784
3785*** --without-gnutls disables automatic GnuTLS detection.
3786
3787*** --lib for general library linkage, works with the USER_LIBS build variable.
3788
3789** New make target `dist' to create binary distribution for MS Windows.
3790
3791** The Lisp function `w32-default-color-map' is now obsolete.
3792(It is only used internally in the Emacs C code.)
3793
3794** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but
3795reappear on mouse-over. (Requires OS X 10.6 or later.)
3796
3797** On Mac OS X, dragging a file into Emacs visits the file, like on
3798other platforms, rather than inserting its contents into the buffer.

29* Tentative plan for Emacs-24 29* Speed up Elisp execution
30** Speed up function calls
31Change src/bytecode.c so that calls from byte-code functions to byte-code
32functions don't go through Ffuncall/funcall_lambda/exec_byte_code but instead
33stay within exec_byte_code.
34
35** Add new `switch' byte-code
36This byte-code would take one argument from the stack (the object to test)
37and one argument from the constant-pool (a switch table, implemented as an
38eq-hashtable) and would jump to the "label" contained in the hashtable.
39
40Then add a `case' special-form that can be compiled to this byte-code.
41This would behave just like cl-case, but instead of expanding to cond+eq it
42would be its own special form and would be compiled specially.
43
44Then change pcase to use `case' when applicable.
45
46Then change the byte-compiler to recognize (cond ((eq x 'foo) bar) ...)
47and turn it into a `case' for more efficient execution.
48
49** Improve the byte-compiler to recognize immutable (lexical) bindings
50and get rid of them if they're used only once and/or they're bound to
51a constant expression.
52
53Such things aren't present in hand-written code, but macro expansion and
54defsubst can often end up generating things like
55(funcall (lambda (arg) (body)) actual) which then get optimized to
56(let ((arg actual)) (body)) but should additionally get optimized further
57when `actual' is a constant/copyable expression.
58
59** Add an "indirect goto" byte-code and use it for local lambda expressions.
60E.g. when you have code like
61
62 (let ((foo (lambda (x) bar)))
63 (dosomething
64 (funcall foo toto)
65 (blabla (funcall foo titi))))
66
67turn those `funcalls' into jumps and their return into indirect jumps back.
68
69** Compile efficiently local recursive functions
70
71Similar to the previous point, we should be able to handle something like
72
73 (letrec ((loop () (blabla) (if (toto) (loop))))
74 (loop))
75
76which ideally should generate the same byte-code as
77
78 (while (progn (blabla) (toto)))

205*** zero-width text-properties. 245(maybe the best backward-compatible way to do that is to make it so that
246PROPERTY can be a cons cell (PLANE . PROP)). So font-lock would
247do (put-text-property start end '(font-lock . face) value).
248
249All the properties coming from the various planes would get merged via an Elisp
250function (so it can merge `face' differently than `keymap' or it could give
251different priorities to different planes (we could imagine enabling/disabling
252planes)). The merging would not happen lazily while looking up properties but
253instead it would take place eagerly in `add-text-properties'. This is based on
254the idea that it's much more frequent to lookup properties than to
255modify them. Also, when properties are looked up during redisplay, we
256generally can't run Elisp code, whereas we generally can do that when
257properties are added.
258
259*** Move overlays to intervals.c
260
261Currently overlays are implemented as (two) sorted singly linked lists (one
262for overlays_before some position and one for overlay_after that
263position, for some quirky definition of "before" and "after").
264The function `overlay-recenter' changes the position used for the split
265(and is called internally in various situations).
266
267Each overlay is itself implemented with two markers (which keep track of
268the overlay-start and overlay-end). Markers are implemented as
269a non-sorted singly linked list of markers. So every text
270insertion/deletion requires O(N) time, where N is the number of markers
271since we have to go down that list to update those markers that are
272affected by the modification.
273
274You can start in src/buffer.[ch], maybe grepping for overlays_before for
275a starting point.
276
277Text-properties, OTOH, are implemented with a (mostly) balanced binary
278tree. This is implemented in src/intervals.[ch].
279
280So we'd like to change overlays so that they don't use markers (and we
281don't keep them in two sorted singly-linked lists) any more. Instead,
282we'll store them inside the balanced binary tree used for
283text-properties. I think we can use the "augmented tree" approach
284described in https://en.wikipedia.org/wiki/Interval_tree.
285
286To ease up debugging during development, I'd guess the implementation
287would first add the new stuff, keeping the old stuff (i.e. add to
288Lisp_Overlay whichever fields are needed for the new code, while keeping
289the old ones, add needed overlay fields to the intervals tree, but keep
290the old fields, the overlays_before etc...). This way, you can add
291consistency checks that make sure the new code computes the same results
292as the old code. And once that works well, we can remove the old code
293and old fields.
