You can use M-x list-load-path-shadows to find such +older packages. + +Some specific packages that are known to cause problems are: + +** Semantic (used by CEDET, ECB, JDEE): upgrade to latest version. + +** cua.el, cua-mode.el: remove old versions. + +* Installation Changes in Emacs 22.2 + +** Emacs is now licensed under the GNU GPL version 3 (or later). + +* Changes in Emacs 22.2 + +** The values of `dired-recursive-deletes' and `dired-recursive-copies' +have been changed to `top'. This means that the user is asked once, +before deleting/copying the indicated directory recursively. + +** In Image mode, whenever the displayed image is wider and/or higher +than the window, the usual keys for moving the cursor cause the image +to be scrolled horizontally or vertically instead. + +** Scrollbars follow the system theme on Windows XP and later. +Windows XP introduced themed scrollbars, but applications have to take +special steps to use them. Emacs now has the appropriate resources linked +in to make it use the scrollbars from the system theme. + +* New Modes and Packages in Emacs 22.2 + ++** bibtex-style-mode helps you write BibTeX's *.bst files. ++ +** The new package css-mode.el provides a major mode for editing CSS files. + +** The new package vera-mode.el provides a major mode for editing Vera files. + +** The new package socks.el implements the SOCKS v5 protocol. + +** VC + +*** VC backends can provide completion of revision names. + +*** VC has some support for Mercurial (hg). + ++*** VC has some support for Bazaar (Bzr). ++ +*** VC has some support for Git. + +* Lisp Changes in Emacs 22.2. + +** New function `window-full-width-p' returns t if a window is as wide +as its frame. + +** The new function `image-refresh' refreshes all images associated +with a given image specification. + ++** The new function `split-string-and-unquote' does (what?) ++ ++** The new function `combine-and-quote-strings' does (what?) + +* Installation Changes in Emacs 22.1 + +** You can build Emacs with Gtk+ widgets by specifying `--with-x-toolkit=gtk' +when you run configure. This requires Gtk+ 2.4 or newer. This port +provides a way to display multilingual text in menus (with some caveats). + +** The Emacs Lisp Reference Manual is now part of the distribution. + +The Emacs Lisp Reference Manual in Info format is built as part of the +Emacs build procedure and installed together with the Emacs User +Manual. A menu item was added to the menu bar to make it easily +accessible (Help->More Manuals->Emacs Lisp Reference). + +** The Introduction to Programming in Emacs Lisp manual is now part of +the distribution. + +This manual is now part of the standard distribution and is installed, +together with the Emacs User Manual, into the Info directory. A menu +item was added to the menu bar to make it easily accessible +(Help->More Manuals->Introduction to Emacs Lisp). + +** Leim is now part of the Emacs distribution. +You no longer need to download a separate tarball in order to build +Emacs with Leim. + +** Support for MacOS X was added. +See the files mac/README and mac/INSTALL for build instructions. + +** Mac OS 9 port now uses the Carbon API by default. You can also +create a non-Carbon build by specifying `NonCarbon' as a target. See +the files mac/README and mac/INSTALL for build instructions. + +** Support for a Cygwin build of Emacs was added. + +** Support for GNU/Linux systems on X86-64 machines was added. + +** Support for GNU/Linux systems on S390 machines was added. + +** Support for GNU/Linux systems on Tensilica Xtensa machines was added. + +** Support for FreeBSD/Alpha has been added. + +** New translations of the Emacs Tutorial are available in the +following languages: Brasilian Portuguese, Bulgarian, Chinese (both +with simplified and traditional characters), French, Russian, and +Italian. Type `C-u C-h t' to choose one of them in case your language +setup doesn't automatically select the right one. + +** New translations of the Emacs reference card are available in the +Brasilian Portuguese and Russian. The corresponding PostScript files +are also included. + +** A French translation of the `Emacs Survival Guide' is available. + +** Emacs now supports new configure options `--program-prefix', +`--program-suffix' and `--program-transform-name' that affect the names of +installed programs. + +** By default, Emacs now uses a setgid helper program to update game +scores. The directory ${localstatedir}/games/emacs is the normal +place for game scores to be stored. You can control this with the +configure option `--with-game-dir'. The specific user that Emacs uses +to own the game scores is controlled by `--with-game-user'. If access +to a game user is not available, then scores will be stored separately +in each user's home directory. + +** Emacs now includes support for loading image libraries on demand. +(Currently this feature is only used on MS Windows.) You can configure +the supported image types and their associated dynamic libraries by +setting the variable `image-library-alist'. + +** Emacs can now be built without sound support. + +** Emacs Lisp source files are compressed by default if `gzip' is available. + +** All images used in Emacs have been consolidated in etc/images and subdirs. +See also the changes to `find-image', documented below. + +** Emacs comes with a new set of icons. +These icons are displayed on the taskbar and/or titlebar when Emacs +runs in a graphical environment. Source files for these icons can be +found in etc/images/icons. (You can't change the icons displayed by +Emacs by changing these files directly. On X, the icon is compiled +into the Emacs executable; see gnu.h in the source tree. On MS +Windows, see nt/icons/emacs.ico.) + +** The `emacsserver' program has been removed, replaced with Lisp code. + +** The `yow' program has been removed. +Use the corresponding Emacs feature instead. + +** The Emacs terminal emulation in term.el uses a different terminfo name. +The Emacs terminal emulation in term.el now uses "eterm-color" as its +terminfo name, since term.el now supports color. + +** The script etc/emacs-buffer.gdb can be used with gdb to retrieve the +contents of buffers from a core dump and save them to files easily, should +Emacs crash. + +** Building with -DENABLE_CHECKING does not automatically build with union +types any more. Add -DUSE_LISP_UNION_TYPE if you want union types. + +** When pure storage overflows while dumping, Emacs now prints how +much pure storage it will approximately need. + + +* Startup Changes in Emacs 22.1 + +** Init file changes +If the init file ~/.emacs does not exist, Emacs will try +~/.emacs.d/init.el or ~/.emacs.d/init.elc. Likewise, if the shell init file +~/.emacs_SHELL is not found, Emacs will try ~/.emacs.d/init_SHELL.sh. + +** Emacs can now be invoked in full-screen mode on a windowed display. +When Emacs is invoked on a window system, the new command-line options +`--fullwidth', `--fullheight', and `--fullscreen' produce a frame +whose width, height, or both width and height take up the entire +screen size. (For now, this does not work with some window managers.) + +** Emacs now displays a splash screen by default even if command-line +arguments were given. The new command-line option --no-splash +disables the splash screen; see also the variable +`inhibit-splash-screen' (which is also aliased as +`inhibit-startup-message'). + +** New user option `inhibit-startup-buffer-menu'. +When loading many files, for instance with `emacs *', Emacs normally +displays a buffer menu. This option turns the buffer menu off. + +** New command line option -nbc or --no-blinking-cursor disables +the blinking cursor on graphical terminals. + +** The option --script FILE runs Emacs in batch mode and loads FILE. +It is useful for writing Emacs Lisp shell script files, because they +can start with this line: + + #!/usr/bin/emacs --script + +** The -f option, used from the command line to call a function, +now reads arguments for the function interactively if it is +an interactively callable function. + +** The option --directory DIR now modifies `load-path' immediately. +Directories are added to the front of `load-path' in the order they +appear on the command line. For example, with this command line: + + emacs -batch -L .. -L /tmp --eval "(require 'foo)" + +Emacs looks for library `foo' in the parent directory, then in /tmp, then +in the other directories in `load-path'. (-L is short for --directory.) + +** When you specify a frame size with --geometry, the size applies to +all frames you create. A position specified with --geometry only +affects the initial frame. + +** Emacs built for MS-Windows now behaves like Emacs on X does, +with respect to its frame position: if you don't specify a position +(in your .emacs init file, in the Registry, or with the --geometry +command-line option), Emacs leaves the frame position to the Windows' +window manager. + +** The command line option --no-windows has been changed to +--no-window-system. The old one still works, but is deprecated. + +** If the environment variable DISPLAY specifies an unreachable X display, +Emacs will now startup as if invoked with the --no-window-system option. + +** Emacs now reads the standard abbrevs file ~/.abbrev_defs +automatically at startup, if it exists. When Emacs offers to save +modified buffers, it saves the abbrevs too if they have changed. It +can do this either silently or asking for confirmation first, +according to the value of `save-abbrevs'. + +** New command line option -Q or --quick. +This is like using -q --no-site-file, but in addition it also disables +the fancy startup screen. + +** New command line option -D or --basic-display. +Disables the menu-bar, the tool-bar, the scroll-bars, tool tips, and +the blinking cursor. + +** The default is now to use a bitmap as the icon. +The command-line options --icon-type, -i have been replaced with +options --no-bitmap-icon, -nbi to turn the bitmap icon off. + +** If the environment variable EMAIL is defined, Emacs now uses its value +to compute the default value of `user-mail-address', in preference to +concatenation of `user-login-name' with the name of your host machine. + + +* Incompatible Editing Changes in Emacs 22.1 + +** You can now follow links by clicking Mouse-1 on the link. + +See below for more details. + +** When the undo information of the current command gets really large +(beyond the value of `undo-outer-limit'), Emacs discards it and warns +you about it. + +** When Emacs prompts for file names, SPC no longer completes the file name. +This is so filenames with embedded spaces could be input without the +need to quote the space with a C-q. The underlying changes in the +keymaps that are active in the minibuffer are described below under +"New keymaps for typing file names". + +If you want the old behavior back, put these two key bindings to your +~/.emacs init file: + + (define-key minibuffer-local-filename-completion-map + " " 'minibuffer-complete-word) + (define-key minibuffer-local-must-match-filename-map + " " 'minibuffer-complete-word) + +** The completion commands TAB, SPC and ? in the minibuffer apply only +to the text before point. If there is text in the buffer after point, +it remains unchanged. + +** In incremental search, C-w is changed. M-%, C-M-w and C-M-y are special. + +See below under "incremental search changes". + +** M-g is now a prefix key. +M-g g and M-g M-g run goto-line. +M-g n and M-g M-n run next-error (like C-x `). +M-g p and M-g M-p run previous-error. + +** C-u M-g M-g switches to the most recent previous buffer, +and goes to the specified line in that buffer. + +When goto-line starts to execute, if there's a number in the buffer at +point then it acts as the default argument for the minibuffer. + +** M-o now is the prefix key for setting text properties; +M-o M-o requests refontification. + +** C-x C-f RET (find-file), typing nothing in the minibuffer, is no longer +a special case. + +Since the default input is the current directory, this has the effect +of specifying the current directory. Normally that means to visit the +directory with Dired. + +You can get the old behavior by typing C-x C-f M-n RET, which fetches +the actual file name into the minibuffer. + +** In Dired's ! command (dired-do-shell-command), `*' and `?' now +control substitution of the file names only when they are surrounded +by whitespace. This means you can now use them as shell wildcards +too. If you want to use just plain `*' as a wildcard, type `*""'; the +doublequotes make no difference in the shell, but they prevent +special treatment in `dired-do-shell-command'. + +** The info-search bindings on C-h C-f, C-h C-k and C-h C-i +have been moved to C-h F, C-h K and C-h S. + +** `apply-macro-to-region-lines' now operates on all lines that begin +in the region, rather than on all complete lines in the region. + +** line-move-ignore-invisible now defaults to t. + +** Adaptive filling misfeature removed. +It no longer treats `NNN.' or `(NNN)' as a prefix. + +** The old bindings C-M-delete and C-M-backspace have been deleted, +since there are situations where one or the other will shut down +the operating system or your X server. + +** The register compatibility key bindings (deprecated since Emacs 19) +have been removed: + C-x / point-to-register (Use: C-x r SPC) + C-x j jump-to-register (Use: C-x r j) + C-x x copy-to-register (Use: C-x r s) + C-x g insert-register (Use: C-x r i) + + +* Editing Changes in Emacs 22.1 + +** The max size of buffers and integers has been doubled. +On 32bit machines, it is now 256M (i.e. 268435455). + +** !MEM FULL! at the start of the mode line indicates that Emacs +cannot get any more memory for Lisp data. This often means it could +crash soon if you do things that use more memory. On most systems, +killing buffers will get out of this state. If killing buffers does +not make !MEM FULL! disappear, you should save your work and start +a new Emacs. + +** `undo-only' does an undo which does not redo any previous undo. + +** Yanking text now discards certain text properties that can +be inconvenient when you did not expect them. The variable +`yank-excluded-properties' specifies which ones. Insertion +of register contents and rectangles also discards these properties. + +** New command `kill-whole-line' kills an entire line at once. +By default, it is bound to C-S-. + +** M-SPC (just-one-space) when given a numeric argument N +converts whitespace around point to N spaces. + +** You can now switch buffers in a cyclic order with C-x C-left +(previous-buffer) and C-x C-right (next-buffer). C-x left and +C-x right can be used as well. The functions keep a different buffer +cycle for each frame, using the frame-local buffer list. + +** C-x 5 C-o displays a specified buffer in another frame +but does not switch to that frame. It's the multi-frame +analogue of C-x 4 C-o. + +** `special-display-buffer-names' and `special-display-regexps' now +understand two new boolean pseudo-frame-parameters `same-frame' and +`same-window'. + +** New commands to operate on pairs of open and close characters: +`insert-pair', `delete-pair', `raise-sexp'. + +** M-x setenv now expands environment variable references. + +Substrings of the form `$foo' and `${foo}' in the specified new value +now refer to the value of environment variable foo. To include a `$' +in the value, use `$$'. + +** The default values of paragraph-start and indent-line-function have +been changed to reflect those used in Text mode rather than those used +in Paragraph-Indent Text mode. + +** The default for the paper size (variable ps-paper-type) is taken +from the locale. + +** Help command changes: + +*** Changes in C-h bindings: + +C-h e displays the *Messages* buffer. + +C-h d runs apropos-documentation. + +C-h r visits the Emacs Manual in Info. + +C-h followed by a control character is used for displaying files + that do not change: + +C-h C-f displays the FAQ. +C-h C-e displays the PROBLEMS file. + +The info-search bindings on C-h C-f, C-h C-k and C-h C-i +have been moved to C-h F, C-h K and C-h S. + +C-h c, C-h k, C-h w, and C-h f now handle remapped interactive commands. +- C-h c and C-h k report the actual command (after possible remapping) + run by the key sequence. +- C-h w and C-h f on a command which has been remapped now report the + command it is remapped to, and the keys which can be used to run + that command. + +For example, if C-k is bound to kill-line, and kill-line is remapped +to new-kill-line, these commands now report: +- C-h c and C-h k C-k reports: + C-k runs the command new-kill-line +- C-h w and C-h f kill-line reports: + kill-line is remapped to new-kill-line which is on C-k, +- C-h w and C-h f new-kill-line reports: + new-kill-line is on C-k + +*** The apropos commands now accept a list of words to match. +When more than one word is specified, at least two of those words must +be present for an item to match. Regular expression matching is still +available. + +*** The new option `apropos-sort-by-scores' causes the matching items +to be sorted according to their score. The score for an item is a +number calculated to indicate how well the item matches the words or +regular expression that you entered to the apropos command. The best +match is listed first, and the calculated score is shown for each +matching item. + +*** Help commands `describe-function' and `describe-key' now show function +arguments in lowercase italics on displays that support it. To change the +default, customize face `help-argument-name' or redefine the function +`help-default-arg-highlight'. + +*** C-h v and C-h f commands now include a hyperlink to the C source for +variables and functions defined in C (if the C source is available). + +*** Help mode now only makes hyperlinks for faces when the face name is +preceded or followed by the word `face'. It no longer makes +hyperlinks for variables without variable documentation, unless +preceded by one of the words `variable' or `option'. It now makes +hyperlinks to Info anchors (or nodes) if the anchor (or node) name is +enclosed in single quotes and preceded by `info anchor' or `Info +anchor' (in addition to earlier `info node' and `Info node'). In +addition, it now makes hyperlinks to URLs as well if the URL is +enclosed in single quotes and preceded by `URL'. + +*** The new command `describe-char' (C-u C-x =) pops up a buffer with +description various information about a character, including its +encodings and syntax, its text properties, how to input, overlays, and +widgets at point. You can get more information about some of them, by +clicking on mouse-sensitive areas or moving there and pressing RET. + +*** The command `list-text-properties-at' has been deleted because +C-u C-x = gives the same information and more. + +*** New command `display-local-help' displays any local help at point +in the echo area. It is bound to `C-h .'. It normally displays the +same string that would be displayed on mouse-over using the +`help-echo' property, but, in certain cases, it can display a more +keyboard oriented alternative. + +*** New user option `help-at-pt-display-when-idle' allows you to +automatically show the help provided by `display-local-help' on +point-over, after suitable idle time. The amount of idle time is +determined by the user option `help-at-pt-timer-delay' and defaults +to one second. This feature is turned off by default. + +** Mark command changes: + +*** A prefix argument is no longer required to repeat a jump to a +previous mark if you set `set-mark-command-repeat-pop' to t. I.e. C-u +C-SPC C-SPC C-SPC ... cycles through the mark ring. Use C-u C-u C-SPC +to set the mark immediately after a jump. + +*** Marking commands extend the region when invoked multiple times. + +If you type C-M-SPC (mark-sexp), M-@ (mark-word), M-h +(mark-paragraph), or C-M-h (mark-defun) repeatedly, the marked region +extends each time, so you can mark the next two sexps with M-C-SPC +M-C-SPC, for example. This feature also works for +mark-end-of-sentence, if you bind that to a key. It also extends the +region when the mark is active in Transient Mark mode, regardless of +the last command. To start a new region with one of marking commands +in Transient Mark mode, you can deactivate the active region with C-g, +or set the new mark with C-SPC. + +*** Some commands do something special in Transient Mark mode when the +mark is active--for instance, they limit their operation to the +region. Even if you don't normally use Transient Mark mode, you might +want to get this behavior from a particular command. There are two +ways you can enable Transient Mark mode and activate the mark, for one +command only. + +One method is to type C-SPC C-SPC; this enables Transient Mark mode +and sets the mark at point. The other method is to type C-u C-x C-x. +This enables Transient Mark mode temporarily but does not alter the +mark or the region. + +After these commands, Transient Mark mode remains enabled until you +deactivate the mark. That typically happens when you type a command +that alters the buffer, but you can also deactivate the mark by typing +C-g. + +*** Movement commands `beginning-of-buffer', `end-of-buffer', +`beginning-of-defun', `end-of-defun' do not set the mark if the mark +is already active in Transient Mark mode. + +*** M-h (mark-paragraph) now accepts a prefix arg. + +With positive arg, M-h marks the current and the following paragraphs; +if the arg is negative, it marks the current and the preceding +paragraphs. + +** Incremental Search changes: + +*** M-% typed in isearch mode invokes `query-replace' or +`query-replace-regexp' (depending on search mode) with the current +search string used as the string to replace. + +*** C-w in incremental search now grabs either a character or a word, +making the decision in a heuristic way. This new job is done by the +command `isearch-yank-word-or-char'. To restore the old behavior, +bind C-w to `isearch-yank-word' in `isearch-mode-map'. + +*** C-y in incremental search now grabs the next line if point is already +at the end of a line. + +*** C-M-w deletes and C-M-y grabs a character in isearch mode. +Another method to grab a character is to enter the minibuffer by `M-e' +and to type `C-f' at the end of the search string in the minibuffer. + +*** Vertical scrolling is now possible within incremental search. +To enable this feature, customize the new user option +`isearch-allow-scroll'. User written commands which satisfy stringent +constraints can be marked as "scrolling commands". See the Emacs manual +for details. + +*** Isearch no longer adds `isearch-resume' commands to the command +history by default. To enable this feature, customize the new +user option `isearch-resume-in-command-history'. + +** Replace command changes: + +*** When used interactively, the commands `query-replace-regexp' and +`replace-regexp' allow \,expr to be used in a replacement string, +where expr is an arbitrary Lisp expression evaluated at replacement +time. `\#' in a replacement string now refers to the count of +replacements already made by the replacement command. All regular +expression replacement commands now allow `\?' in the replacement +string to specify a position where the replacement string can be +edited for each replacement. `query-replace-regexp-eval' is now +deprecated since it offers no additional functionality. + +*** query-replace uses isearch lazy highlighting when the new user option +`query-replace-lazy-highlight' is non-nil. + +*** The current match in query-replace is highlighted in new face +`query-replace' which by default inherits from isearch face. + +*** New user option `query-replace-skip-read-only': when non-nil, +`query-replace' and related functions simply ignore +a match if part of it has a read-only property. + +** Local variables lists: + +*** If the local variables list contains any variable-value pairs that +are not known to be safe, Emacs shows a prompt asking whether to apply +the local variables list as a whole. In earlier versions, a prompt +was only issued for variables explicitly marked as risky (for the +definition of risky variables, see `risky-local-variable-p'). + +At the prompt, you can choose to save the contents of this local +variables list to `safe-local-variable-values'. This new customizable +option is a list of variable-value pairs that are known to be safe. +Variables can also be marked as safe with the existing +`safe-local-variable' property (see `safe-local-variable-p'). +However, risky variables will not be added to +`safe-local-variable-values' in this way. + +*** The variable `enable-local-variables' controls how local variable +lists are handled. t, the default, specifies the standard querying +behavior. :safe means use only safe values, and ignore the rest. +:all means set all variables, whether or not they are safe. +nil means ignore them all. Anything else means always query. + +*** The variable `safe-local-eval-forms' specifies a list of forms that +are ok to evaluate when they appear in an `eval' local variables +specification. Normally Emacs asks for confirmation before evaluating +such a form, but if the form appears in this list, no confirmation is +needed. + +*** If a function has a non-nil `safe-local-eval-function' property, +that means it is ok to evaluate some calls to that function when it +appears in an `eval' local variables specification. If the property +is t, then any form calling that function with constant arguments is +ok. If the property is a function or list of functions, they are called +with the form as argument, and if any returns t, the form is ok to call. + +If the form is not "ok to call", that means Emacs asks for +confirmation as before. + +*** In processing a local variables list, Emacs strips the prefix and +suffix from every line before processing all the lines. + +*** Text properties in local variables. + +A file local variables list cannot specify a string with text +properties--any specified text properties are discarded. + +** File operation changes: + +*** Unquoted `$' in file names do not signal an error any more when +the corresponding environment variable does not exist. +Instead, the `$ENVVAR' text is left as is, so that `$$' quoting +is only rarely needed. + +*** C-x C-f RET, typing nothing in the minibuffer, is no longer a special case. + +Since the default input is the current directory, this has the effect +of specifying the current directory. Normally that means to visit the +directory with Dired. + +*** C-x s (save-some-buffers) now offers an option `d' to diff a buffer +against its file, so you can see what changes you would be saving. + +*** Auto Compression mode is now enabled by default. + +*** If the user visits a file larger than `large-file-warning-threshold', +Emacs asks for confirmation. + +*** The commands copy-file, rename-file, make-symbolic-link and +add-name-to-file, when given a directory as the "new name" argument, +convert it to a file name by merging in the within-directory part of +the existing file's name. (This is the same convention that shell +commands cp, mv, and ln follow.) Thus, M-x copy-file RET ~/foo RET +/tmp RET copies ~/foo to /tmp/foo. + +*** require-final-newline now has two new possible values: + +`visit' means add a newline (as an undoable change) if it's needed +when visiting the file. + +`visit-save' means add a newline (as an undoable change) if it's +needed when visiting the file, and also add a newline if it's needed +when saving the file. + +*** The new option mode-require-final-newline controls how certain +major modes enable require-final-newline. Any major mode that's +designed for a kind of file that should normally end in a newline +sets require-final-newline based on mode-require-final-newline. +So you can customize mode-require-final-newline to control what these +modes do. + +*** When you are root, and you visit a file whose modes specify +read-only, the Emacs buffer is now read-only too. Type C-x C-q if you +want to make the buffer writable. (As root, you can in fact alter the +file.) + +*** find-file-read-only visits multiple files in read-only mode, +when the file name contains wildcard characters. + +*** find-alternate-file replaces the current file with multiple files, +when the file name contains wildcard characters. It now asks if you +wish save your changes and not just offer to kill the buffer. + +*** When used interactively, `format-write-file' now asks for confirmation +before overwriting an existing file, unless a prefix argument is +supplied. This behavior is analogous to `write-file'. + +*** The variable `auto-save-file-name-transforms' now has a third element that +controls whether or not the function `make-auto-save-file-name' will +attempt to construct a unique auto-save name (e.g. for remote files). + +*** The new option `write-region-inhibit-fsync' disables calls to fsync +in `write-region'. This can be useful on laptops to avoid spinning up +the hard drive upon each file save. Enabling this variable may result +in data loss, use with care. + +** Minibuffer changes: + +*** The completion commands TAB, SPC and ? in the minibuffer apply only +to the text before point. If there is text in the buffer after point, +it remains unchanged. + +*** The new file-name-shadow-mode is turned ON by default, so that when +entering a file name, any prefix which Emacs will ignore is dimmed. + +*** There's a new face `minibuffer-prompt'. +Emacs adds this face to the list of text properties stored in the +variable `minibuffer-prompt-properties', which is used to display the +prompt string. + +*** Enhanced visual feedback in `*Completions*' buffer. + +Completions lists use faces to highlight what all completions +have in common and where they begin to differ. + +The common prefix shared by all possible completions uses the face +`completions-common-part', while the first character that isn't the +same uses the face `completions-first-difference'. By default, +`completions-common-part' inherits from `default', and +`completions-first-difference' inherits from `bold'. The idea of +`completions-common-part' is that you can use it to make the common +parts less visible than normal, so that the rest of the differing +parts is, by contrast, slightly highlighted. + +Above fontification is always done when listing completions is +triggered at minibuffer. If you want to fontify completions whose +listing is triggered at the other normal buffer, you have to pass +the common prefix of completions to `display-completion-list' as +its second argument. + +*** File-name completion can now ignore specified directories. +If an element of the list in `completion-ignored-extensions' ends in a +slash `/', it indicates a subdirectory that should be ignored when +completing file names. Elements of `completion-ignored-extensions' +which do not end in a slash are never considered when a completion +candidate is a directory. + +*** New user option `history-delete-duplicates'. +If set to t when adding a new history element, all previous identical +elements are deleted from the history list. + +** Redisplay changes: + +*** The new face `mode-line-inactive' is used to display the mode line +of non-selected windows. The `mode-line' face is now used to display +the mode line of the currently selected window. + +The new variable `mode-line-in-non-selected-windows' controls whether +the `mode-line-inactive' face is used. + +*** The mode line position information now comes before the major mode. +When the file is maintained under version control, that information +appears between the position information and the major mode. + +*** You can now customize the use of window fringes. To control this +for all frames, use M-x fringe-mode or the Show/Hide submenu of the +top-level Options menu, or customize the `fringe-mode' variable. To +control this for a specific frame, use the command M-x +set-fringe-style. + +*** Angle icons in the fringes can indicate the buffer boundaries. In +addition, up and down arrow bitmaps in the fringe indicate which ways +the window can be scrolled. + +This behavior is activated by setting the buffer-local variable +`indicate-buffer-boundaries' to a non-nil value. The default value of +this variable is found in `default-indicate-buffer-boundaries'. + +If value is `left' or `right', both angle and arrow bitmaps are +displayed in the left or right fringe, resp. + +The value can also be an alist which specifies the presence and +position of each bitmap individually. + +For example, ((top . left) (t . right)) places the top angle bitmap +in left fringe, the bottom angle bitmap in right fringe, and both +arrow bitmaps in right fringe. To show just the angle bitmaps in the +left fringe, but no arrow bitmaps, use ((top . left) (bottom . left)). + +*** On window systems, lines which are exactly as wide as the window +(not counting the final newline character) are no longer broken into +two lines on the display (with just the newline on the second line). +Instead, the newline now "overflows" into the right fringe, and the +cursor will be displayed in the fringe when positioned on that newline. + +The new user option 'overflow-newline-into-fringe' can be set to nil to +revert to the old behavior of continuing such lines. + +*** A window can now have individual fringe and scroll-bar settings, +in addition to the individual display margin settings. + +Such individual settings are now preserved when windows are split +horizontally or vertically, a saved window configuration is restored, +or when the frame is resized. + +*** When a window has display margin areas, the fringes are now +displayed between the margins and the buffer's text area, rather than +outside those margins. + +*** New face `escape-glyph' highlights control characters and escape glyphs. + +*** Non-breaking space and hyphens are now displayed with a special +face, either nobreak-space or escape-glyph. You can turn this off or +specify a different mode by setting the variable `nobreak-char-display'. + +*** The parameters of automatic hscrolling can now be customized. +The variable `hscroll-margin' determines how many columns away from +the window edge point is allowed to get before automatic hscrolling +will horizontally scroll the window. The default value is 5. + +The variable `hscroll-step' determines how many columns automatic +hscrolling scrolls the window when point gets too close to the +window edge. If its value is zero, the default, Emacs scrolls the +window so as to center point. If its value is an integer, it says how +many columns to scroll. If the value is a floating-point number, it +gives the fraction of the window's width to scroll the window. + +The variable `automatic-hscrolling' was renamed to +`auto-hscroll-mode'. The old name is still available as an alias. + +*** Moving or scrolling through images (and other lines) taller than +the window now works sensibly, by automatically adjusting the window's +vscroll property. + +*** Preemptive redisplay now adapts to current load and bandwidth. + +To avoid preempting redisplay on fast computers, networks, and displays, +the arrival of new input is now performed at regular intervals during +redisplay. The new variable `redisplay-preemption-period' specifies +the period; the default is to check for input every 0.1 seconds. + +*** The %c and %l constructs are now ignored in frame-title-format. +Due to technical limitations in how Emacs interacts with windowing +systems, these constructs often failed to render properly, and could +even cause Emacs to crash. + +*** If value of `auto-resize-tool-bars' is `grow-only', the tool bar +will expand as needed, but not contract automatically. To contract +the tool bar, you must type C-l. + +*** New customize option `overline-margin' controls the space between +overline and text. + +*** New variable `x-underline-at-descent-line' controls the relative +position of the underline. When set, it overrides the +`x-use-underline-position-properties' variables. + +** New faces: + +*** `mode-line-highlight' is the standard face indicating mouse sensitive +elements on mode-line (and header-line) like `highlight' face on text +areas. + +*** `mode-line-buffer-id' is the standard face for buffer identification +parts of the mode line. + +*** `shadow' face defines the appearance of the "shadowed" text, i.e. +the text which should be less noticeable than the surrounding text. +This can be achieved by using shades of grey in contrast with either +black or white default foreground color. This generic shadow face +allows customization of the appearance of shadowed text in one place, +so package-specific faces can inherit from it. + +*** `vertical-border' face is used for the vertical divider between windows. + +** Font-Lock (syntax highlighting) changes: + +*** All modes now support using M-x font-lock-mode to toggle +fontification, even those such as Occur, Info, and comint-derived +modes that do their own fontification in a special way. + +The variable `Info-fontify' is no longer applicable; to disable +fontification in Info, remove `turn-on-font-lock' from +`Info-mode-hook'. + +*** New standard font-lock face `font-lock-comment-delimiter-face'. + +*** New standard font-lock face `font-lock-preprocessor-face'. + +*** Easy to overlook single character negation can now be font-locked. +You can use the new variable `font-lock-negation-char-face' and the face of +the same name to customize this. Currently the cc-modes, sh-script-mode, +cperl-mode and make-mode support this. + +*** Font-Lock mode: in major modes such as Lisp mode, where some Emacs +features assume that an open-paren in column 0 is always outside of +any string or comment, Font-Lock now highlights any such open-paren in +bold-red if it is inside a string or a comment, to indicate that it +can cause trouble. You should rewrite the string or comment so that +the open-paren is not in column 0. + +*** M-o now is the prefix key for setting text properties; +M-o M-o requests refontification. + +*** The default settings for JIT stealth lock parameters are changed. +The default value for the user option jit-lock-stealth-time is now nil +instead of 3. This setting of jit-lock-stealth-time disables stealth +fontification: on today's machines, it may be a bug in font lock +patterns if fontification otherwise noticeably degrades interactivity. +If you find movement in infrequently visited buffers sluggish (and the +major mode maintainer has no better idea), customizing +jit-lock-stealth-time to a non-nil value will let Emacs fontify +buffers in the background when it considers the system to be idle. +jit-lock-stealth-nice is now 0.5 instead of 0.125 which is supposed to +cause less load than the old defaults. + +*** jit-lock can now be delayed with `jit-lock-defer-time'. + +If this variable is non-nil, its value should be the amount of Emacs +idle time in seconds to wait before starting fontification. For +example, if you set `jit-lock-defer-time' to 0.25, fontification will +only happen after 0.25s of idle time. + +*** contextual refontification is now separate from stealth fontification. + +jit-lock-defer-contextually is renamed jit-lock-contextually and +jit-lock-context-time determines the delay after which contextual +refontification takes place. + +*** lazy-lock is considered obsolete. + +The `lazy-lock' package is superseded by `jit-lock' and is considered +obsolete. `jit-lock' is activated by default; if you wish to continue +using `lazy-lock', activate it in your ~/.emacs like this: + (setq font-lock-support-mode 'lazy-lock-mode) + +If you invoke `lazy-lock-mode' directly rather than through +`font-lock-support-mode', it now issues a warning: + "Use font-lock-support-mode rather than calling lazy-lock-mode" + +** Menu support: + +*** A menu item "Show/Hide" was added to the top-level menu "Options". +This menu allows you to turn various display features on and off (such +as the fringes, the tool bar, the speedbar, and the menu bar itself). +You can also move the vertical scroll bar to either side here or turn +it off completely. There is also a menu-item to toggle displaying of +current date and time, current line and column number in the mode-line. + +*** Speedbar has moved from the "Tools" top level menu to "Show/Hide". + +*** The menu item "Open File..." has been split into two items, "New File..." +and "Open File...". "Open File..." now opens only existing files. This is +to support existing GUI file selection dialogs better. + +*** The file selection dialog for Gtk+, Mac, W32 and Motif/LessTif can be +disabled by customizing the variable `use-file-dialog'. + +*** The pop up menus for Lucid now stay up if you do a fast click and can +be navigated with the arrow keys (like Gtk+, Mac and W32). + +*** The menu bar for Motif/LessTif/Lucid/Gtk+ can be navigated with keys. +Pressing F10 shows the first menu in the menu bar. Navigation is done with +the arrow keys, select with the return key and cancel with the escape keys. + +*** The Lucid menus can display multilingual text in your locale. You have +to explicitly specify a fontSet resource for this to work, for example +`-xrm "Emacs*fontSet: -*-helvetica-medium-r-*--*-120-*-*-*-*-*-*,*"'. + +*** Dialogs for Lucid/Athena and LessTif/Motif now pop down on pressing +ESC, like they do for Gtk+, Mac and W32. + +*** For the Gtk+ version, you can make Emacs use the old file dialog +by setting the variable `x-gtk-use-old-file-dialog' to t. Default is to use +the new dialog. + +*** You can exit dialog windows and menus by typing C-g. + +** Buffer Menu changes: + +*** The new options `buffers-menu-show-directories' and +`buffers-menu-show-status' let you control how buffers are displayed +in the menu dropped down when you click "Buffers" from the menu bar. + +`buffers-menu-show-directories' controls whether the menu displays +leading directories as part of the file name visited by the buffer. +If its value is `unless-uniquify', the default, directories are +shown unless uniquify-buffer-name-style' is non-nil. The value of nil +and t turn the display of directories off and on, respectively. + +`buffers-menu-show-status' controls whether the Buffers menu includes +the modified and read-only status of the buffers. By default it is +t, and the status is shown. + +Setting these variables directly does not take effect until next time +the Buffers menu is regenerated. + +*** New command `Buffer-menu-toggle-files-only' toggles display of file +buffers only in the Buffer Menu. It is bound to T in Buffer Menu +mode. + +*** `buffer-menu' and `list-buffers' now list buffers whose names begin +with a space, when those buffers are visiting files. Normally buffers +whose names begin with space are omitted. + +** Mouse changes: + +*** You can now follow links by clicking Mouse-1 on the link. + +Traditionally, Emacs uses a Mouse-1 click to set point and a Mouse-2 +click to follow a link, whereas most other applications use a Mouse-1 +click for both purposes, depending on whether you click outside or +inside a link. Now the behavior of a Mouse-1 click has been changed +to match this context-sensitive dual behavior. (If you prefer the old +behavior, set the user option `mouse-1-click-follows-link' to nil.) + +Depending on the current mode, a Mouse-2 click in Emacs can do much +more than just follow a link, so the new Mouse-1 behavior is only +activated for modes which explicitly mark a clickable text as a "link" +(see the new function `mouse-on-link-p' for details). The Lisp +packages that are included in release 22.1 have been adapted to do +this, but external packages may not yet support this. However, there +is no risk in using such packages, as the worst thing that could +happen is that you get the original Mouse-1 behavior when you click +on a link, which typically means that you set point where you click. + +If you want to get the original Mouse-1 action also inside a link, you +just need to press the Mouse-1 button a little longer than a normal +click (i.e. press and hold the Mouse-1 button for half a second before +you release it). + +Dragging the Mouse-1 inside a link still performs the original +drag-mouse-1 action, typically copy the text. + +You can customize the new Mouse-1 behavior via the new user options +`mouse-1-click-follows-link' and `mouse-1-click-in-non-selected-windows'. + +*** If you set the new variable `mouse-autoselect-window' to a non-nil +value, windows are automatically selected as you move the mouse from +one Emacs window to another, even within a frame. A minibuffer window +can be selected only when it is active. + +*** On X, when the window manager requires that you click on a frame to +select it (give it focus), the selected window and cursor position +normally changes according to the mouse click position. If you set +the variable x-mouse-click-focus-ignore-position to t, the selected +window and cursor position do not change when you click on a frame +to give it focus. + +*** Emacs normally highlights mouse sensitive text whenever the mouse +is over the text. By setting the new variable `mouse-highlight', you +can optionally enable mouse highlighting only after you move the +mouse, so that highlighting disappears when you press a key. You can +also disable mouse highlighting. + +*** You can now customize if selecting a region by dragging the mouse +shall not copy the selected text to the kill-ring by setting the new +variable mouse-drag-copy-region to nil. + +*** Under X, mouse-wheel-mode is turned on by default. + +*** Emacs ignores mouse-2 clicks while the mouse wheel is being moved. + +People tend to push the mouse wheel (which counts as a mouse-2 click) +unintentionally while turning the wheel, so these clicks are now +ignored. You can customize this with the mouse-wheel-click-event and +mouse-wheel-inhibit-click-time variables. + +*** mouse-wheels can now scroll a specific fraction of the window +(rather than a fixed number of lines) and the scrolling is `progressive'. + +** Multilingual Environment (Mule) changes: + +*** You can disable character translation for a file using the -*- +construct. Include `enable-character-translation: nil' inside the +-*-...-*- to disable any character translation that may happen by +various global and per-coding-system translation tables. You can also +specify it in a local variable list at the end of the file. For +shortcut, instead of using this long variable name, you can append the +character "!" at the end of coding-system name specified in -*- +construct or in a local variable list. For example, if a file has the +following header, it is decoded by the coding system `iso-latin-1' +without any character translation: +;; -*- coding: iso-latin-1!; -*- + +*** Language environment and various default coding systems are setup +more correctly according to the current locale name. If the locale +name doesn't specify a charset, the default is what glibc defines. +This change can result in using the different coding systems as +default in some locale (e.g. vi_VN). + +*** The keyboard-coding-system is now automatically set based on your +current locale settings if you are not using a window system. This +can mean that the META key doesn't work but generates non-ASCII +characters instead, depending on how the terminal (or terminal +emulator) works. Use `set-keyboard-coding-system' (or customize +keyboard-coding-system) if you prefer META to work (the old default) +or if the locale doesn't describe the character set actually generated +by the keyboard. See Info node `Unibyte Mode'. + +*** The new command `set-file-name-coding-system' (C-x RET F) sets +coding system for encoding and decoding file names. A new menu item +(Options->Mule->Set Coding Systems->For File Name) invokes this +command. + +*** The new command `revert-buffer-with-coding-system' (C-x RET r) +revisits the current file using a coding system that you specify. + +*** New command `recode-region' decodes the region again by a specified +coding system. + +*** The new command `recode-file-name' changes the encoding of the name +of a file. + +*** New command `ucs-insert' inserts a character specified by its +unicode. + +*** New command quail-show-key shows what key (or key sequence) to type +in the current input method to input a character at point. + +*** Limited support for character `unification' has been added. +Emacs now knows how to translate between different representations of +the same characters in various Emacs charsets according to standard +Unicode mappings. This applies mainly to characters in the ISO 8859 +sets plus some other 8-bit sets, but can be extended. For instance, +translation works amongst the Emacs ...-iso8859-... charsets and the +mule-unicode-... ones. + +By default this translation happens automatically on encoding. +Self-inserting characters are translated to make the input conformant +with the encoding of the buffer in which it's being used, where +possible. + +You can force a more complete unification with the user option +unify-8859-on-decoding-mode. That maps all the Latin-N character sets +into Unicode characters (from the latin-iso8859-1 and +mule-unicode-0100-24ff charsets) on decoding. Note that this mode +will often effectively clobber data with an iso-2022 encoding. + +*** New language environments (set up automatically according to the +locale): Belarusian, Bulgarian, Chinese-EUC-TW, Croatian, Esperanto, +French, Georgian, Italian, Latin-7, Latvian, Lithuanian, Malayalam, +Russian, Russian, Slovenian, Swedish, Tajik, Tamil, UTF-8,Ukrainian, +Welsh,Latin-6, Windows-1255. + +*** New input methods: latin-alt-postfix, latin-postfix, latin-prefix, +belarusian, bulgarian-bds, bulgarian-phonetic, chinese-sisheng (for +Chinese Pinyin characters), croatian, dutch, georgian, latvian-keyboard, +lithuanian-numeric, lithuanian-keyboard, malayalam-inscript, rfc1345, +russian-computer, sgml, slovenian, tamil-inscript, ukrainian-computer, +ucs, vietnamese-telex, welsh. + +*** There is support for decoding Greek and Cyrillic characters into +either Unicode (the mule-unicode charsets) or the iso-8859 charsets, +when possible. The latter are more space-efficient. + This is controlled by user option utf-fragment-on-decoding. + +*** Improved Thai support. A new minor mode `thai-word-mode' (which is +automatically activated if you select Thai as a language +environment) changes key bindings of most word-oriented commands to +versions which recognize Thai words. Affected commands are + M-f (forward-word) + M-b (backward-word) + M-d (kill-word) + M-DEL (backward-kill-word) + M-t (transpose-words) + M-q (fill-paragraph) + +*** Indian support has been updated. +The in-is13194 coding system is now Unicode-based. CDAC fonts are +assumed. There is a framework for supporting various Indian scripts, +but currently only Devanagari, Malayalam and Tamil are supported. + +*** The utf-8/16 coding systems have been enhanced. +By default, untranslatable utf-8 sequences are simply composed into +single quasi-characters. User option `utf-translate-cjk-mode' (it is +turned on by default) arranges to translate many utf-8 CJK character +sequences into real Emacs characters in a similar way to the Mule-UCS +system. As this loads a fairly big data on demand, people who are not +interested in CJK characters may want to customize it to nil. +You can augment/amend the CJK translation via hash tables +`ucs-mule-cjk-to-unicode' and `ucs-unicode-to-mule-cjk'. The utf-8 +coding system now also encodes characters from most of Emacs's +one-dimensional internal charsets, specifically the ISO-8859 ones. +The utf-16 coding system is affected similarly. + +*** A UTF-7 coding system is available in the library `utf-7'. + +*** A new coding system `euc-tw' has been added for traditional Chinese +in CNS encoding; it accepts both Big 5 and CNS as input; on saving, +Big 5 is then converted to CNS. + +*** Many new coding systems are available in the `code-pages' library. +These include complete versions of most of those in codepage.el, based +on Unicode mappings. `codepage-setup' is now obsolete and is used +only in the MS-DOS port of Emacs. All coding systems defined in +`code-pages' are auto-loaded. + +*** New variable `utf-translate-cjk-unicode-range' controls which +Unicode characters to translate in `utf-translate-cjk-mode'. + +*** iso-10646-1 (`Unicode') fonts can be used to display any range of +characters encodable by the utf-8 coding system. Just specify the +fontset appropriately. + +** Customize changes: + +*** Custom themes are collections of customize options. Create a +custom theme with M-x customize-create-theme. Use M-x load-theme to +load and enable a theme, and M-x disable-theme to disable it. Use M-x +enable-theme to enable a disabled theme. + +*** The commands M-x customize-face and M-x customize-face-other-window +now look at the character after point. If a face or faces are +specified for that character, the commands by default customize those +faces. + +*** The face-customization widget has been reworked to be less confusing. +In particular, when you enable a face attribute using the corresponding +check-box, there's no longer a redundant `*' option in value selection +for that attribute; the values you can choose are only those which make +sense for the attribute. When an attribute is de-selected by unchecking +its check-box, then the (now ignored, but still present temporarily in +case you re-select the attribute) value is hidden. + +*** When you set or reset a variable's value in a Customize buffer, +the previous value becomes the "backup value" of the variable. +You can go back to that backup value by selecting "Use Backup Value" +under the "[State]" button. + +** Dired mode: + +*** In Dired's ! command (dired-do-shell-command), `*' and `?' now +control substitution of the file names only when they are surrounded +by whitespace. This means you can now use them as shell wildcards +too. If you want to use just plain `*' as a wildcard, type `*""'; the +double quotes make no difference in the shell, but they prevent +special treatment in `dired-do-shell-command'. + +*** The Dired command `dired-goto-file' is now bound to j, not M-g. +This is to avoid hiding the global key binding of M-g. + +*** New faces dired-header, dired-mark, dired-marked, dired-flagged, +dired-ignored, dired-directory, dired-symlink, dired-warning +introduced for Dired mode instead of font-lock faces. + +*** New Dired command `dired-compare-directories' marks files +with different file attributes in two dired buffers. + +*** New Dired command `dired-do-touch' (bound to T) changes timestamps +of marked files with the value entered in the minibuffer. + +*** In Dired, the w command now stores the current line's file name +into the kill ring. With a zero prefix arg, it stores the absolute file name. + +*** In Dired-x, Omitting files is now a minor mode, dired-omit-mode. + +The mode toggling command is bound to M-o. A new command +dired-mark-omitted, bound to * O, marks omitted files. The variable +dired-omit-files-p is obsoleted, use the mode toggling function +instead. + +*** The variables dired-free-space-program and dired-free-space-args +have been renamed to directory-free-space-program and +directory-free-space-args, and they now apply whenever Emacs puts a +directory listing into a buffer. + +** Comint changes: + +*** The new INSIDE_EMACS environment variable is set to "t" in subshells +running inside Emacs. This supersedes the EMACS environment variable, +which will be removed in a future Emacs release. Programs that need +to know whether they are started inside Emacs should check INSIDE_EMACS +instead of EMACS. + +*** The comint prompt can now be made read-only, using the new user +option `comint-prompt-read-only'. This is not enabled by default, +except in IELM buffers. The read-only status of IELM prompts can be +controlled with the new user option `ielm-prompt-read-only', which +overrides `comint-prompt-read-only'. + +The new commands `comint-kill-whole-line' and `comint-kill-region' +support editing comint buffers with read-only prompts. + +`comint-kill-whole-line' is like `kill-whole-line', but ignores both +read-only and field properties. Hence, it always kill entire +lines, including any prompts. + +`comint-kill-region' is like `kill-region', except that it ignores +read-only properties, if it is safe to do so. This means that if any +part of a prompt is deleted, then the entire prompt must be deleted +and that all prompts must stay at the beginning of a line. If this is +not the case, then `comint-kill-region' behaves just like +`kill-region' if read-only properties are involved: it copies the text +to the kill-ring, but does not delete it. + +*** The new command `comint-insert-previous-argument' in comint-derived +modes (shell-mode, etc.) inserts arguments from previous command lines, +like bash's `ESC .' binding. It is bound by default to `C-c .', but +otherwise behaves quite similarly to the bash version. + +*** `comint-use-prompt-regexp-instead-of-fields' has been renamed +`comint-use-prompt-regexp'. The old name has been kept as an alias, +but declared obsolete. + +** M-x Compile changes: + +*** M-x compile has become more robust and reliable + +Quite a few more kinds of messages are recognized. Messages that are +recognized as warnings or informational come in orange or green, instead of +red. Informational messages are by default skipped with `next-error' +(controlled by `compilation-skip-threshold'). + +Location data is collected on the fly as the *compilation* buffer changes. +This means you could modify messages to make them point to different files. +This also means you can not go to locations of messages you may have deleted. + +The variable `compilation-error-regexp-alist' has now become customizable. If +you had added your own regexps to this, you'll probably need to include a +leading `^', otherwise they'll match anywhere on a line. There is now also a +`compilation-mode-font-lock-keywords' and it nicely handles all the checks +that configure outputs and -o options so you see at a glance where you are. + +The new file etc/compilation.txt gives examples of each type of message. + +*** New user option `compilation-environment'. +This option allows you to specify environment variables for inferior +compilation processes without affecting the environment that all +subprocesses inherit. + +*** New user option `compilation-disable-input'. +If this is non-nil, send end-of-file as compilation process input. + +*** New options `next-error-highlight' and `next-error-highlight-no-select' +specify the method of highlighting of the corresponding source line +in new face `next-error'. + +*** A new minor mode `next-error-follow-minor-mode' can be used in +compilation-mode, grep-mode, occur-mode, and diff-mode (i.e. all the +modes that can use `next-error'). In this mode, cursor motion in the +buffer causes automatic display in another window of the corresponding +matches, compilation errors, etc. This minor mode can be toggled with +C-c C-f. + +*** When the left fringe is displayed, an arrow points to current message in +the compilation buffer. + +*** The new variable `compilation-context-lines' controls lines of leading +context before the current message. If nil and the left fringe is displayed, +it doesn't scroll the compilation output window. If there is no left fringe, +no arrow is displayed and a value of nil means display the message at the top +of the window. + +** Occur mode changes: + +*** The new command `multi-occur' is just like `occur', except it can +search multiple buffers. There is also a new command +`multi-occur-in-matching-buffers' which allows you to specify the +buffers to search by their filenames or buffer names. Internally, +Occur mode has been rewritten, and now uses font-lock, among other +changes. + +*** You can now use next-error (C-x `) and previous-error to advance to +the next/previous matching line found by M-x occur. + +*** In the *Occur* buffer, `o' switches to it in another window, and +C-o displays the current line's occurrence in another window without +switching to it. + +** Grep changes: + +*** Grep has been decoupled from compilation mode setup. + +There's a new separate package grep.el, with its own submenu and +customization group. + +*** `grep-find' is now also available under the name `find-grep' where +people knowing `find-grep-dired' would probably expect it. + +*** New commands `lgrep' (local grep) and `rgrep' (recursive grep) are +more user-friendly versions of `grep' and `grep-find', which prompt +separately for the regular expression to match, the files to search, +and the base directory for the search. Case sensitivity of the +search is controlled by the current value of `case-fold-search'. + +These commands build the shell commands based on the new variables +`grep-template' (lgrep) and `grep-find-template' (rgrep). + +The files to search can use aliases defined in `grep-files-aliases'. + +Subdirectories listed in `grep-find-ignored-directories' such as those +typically used by various version control systems, like CVS and arch, +are automatically skipped by `rgrep'. + +*** The grep commands provide highlighting support. + +Hits are fontified in green, and hits in binary files in orange. Grep buffers +can be saved and automatically revisited. + +*** New option `grep-highlight-matches' highlights matches in *grep* +buffer. It uses a special feature of some grep programs which accept +--color option to output markers around matches. When going to the next +match with `next-error' the exact match is highlighted in the source +buffer. Otherwise, if `grep-highlight-matches' is nil, the whole +source line is highlighted. + +*** New key bindings in grep output window: +SPC and DEL scrolls window up and down. C-n and C-p moves to next and +previous match in the grep window. RET jumps to the source line of +the current match. `n' and `p' shows next and previous match in +other window, but does not switch buffer. `{' and `}' jumps to the +previous or next file in the grep output. TAB also jumps to the next +file. + +*** M-x grep now tries to avoid appending `/dev/null' to the command line +by using GNU grep `-H' option instead. M-x grep automatically +detects whether this is possible or not the first time it is invoked. +When `-H' is used, the grep command line supplied by the user is passed +unchanged to the system to execute, which allows more complicated +command lines to be used than was possible before. + +*** The new variables `grep-window-height' and `grep-scroll-output' override +the corresponding compilation mode settings, for grep commands only. + +** Cursor display changes: + +*** Emacs can produce an underscore-like (horizontal bar) cursor. +The underscore cursor is set by putting `(cursor-type . hbar)' in +default-frame-alist. It supports variable heights, like the `bar' +cursor does. + +*** The variable `cursor-in-non-selected-windows' can now be set to any +of the recognized cursor types. + +*** Display of hollow cursors now obeys the buffer-local value (if any) +of `cursor-in-non-selected-windows' in the buffer that the cursor +appears in. + +*** On text terminals, the variable `visible-cursor' controls whether Emacs +uses the "very visible" cursor (the default) or the normal cursor. + +*** The X resource cursorBlink can be used to turn off cursor blinking. + +*** On X, MS Windows, and Mac OS, the blinking cursor's "off" state is +now controlled by the variable `blink-cursor-alist'. + +** X Windows Support: + +*** Emacs now supports drag and drop for X. Dropping a file on a window +opens it, dropping text inserts the text. Dropping a file on a dired +buffer copies or moves the file to that directory. + +*** Under X11, it is possible to swap Alt and Meta (and Super and Hyper). +The new variables `x-alt-keysym', `x-hyper-keysym', `x-meta-keysym', +and `x-super-keysym' can be used to choose which keysyms Emacs should +use for the modifiers. For example, the following two lines swap +Meta and Alt: + (setq x-alt-keysym 'meta) + (setq x-meta-keysym 'alt) + +*** The X resource useXIM can be used to turn off use of XIM, which can +speed up Emacs with slow networking to the X server. + +If the configure option `--without-xim' was used to turn off use of +XIM by default, the X resource useXIM can be used to turn it on. + +*** The new variable `x-select-request-type' controls how Emacs +requests X selection. The default value is nil, which means that +Emacs requests X selection with types COMPOUND_TEXT and UTF8_STRING, +and use the more appropriately result. + +*** The scrollbar under LessTif or Motif has a smoother drag-scrolling. +On the other hand, the size of the thumb does not represent the actual +amount of text shown any more (only a crude approximation of it). + +** Xterm support: + +*** If you enable Xterm Mouse mode, Emacs will respond to mouse clicks +on the mode line, header line and display margin, when run in an xterm. + +*** Improved key bindings support when running in an xterm. +When Emacs is running in an xterm more key bindings are available. +The following should work: +{C,S,C-S,A}-{right,left,up,down,prior,next,delete,insert,F1-12}. +These key bindings work on xterm from X.org 6.8 (and later versions), +they might not work on some older versions of xterm, or on some +proprietary versions. +The various keys generated by xterm when the "modifyOtherKeys" +resource is set are also supported. + +** Character terminal color support changes: + +*** The new command-line option --color=MODE lets you specify a standard +mode for a tty color support. It is meant to be used on character +terminals whose capabilities are not set correctly in the terminal +database, or with terminal emulators which support colors, but don't +set the TERM environment variable to a name of a color-capable +terminal. "emacs --color" uses the same color commands as GNU `ls' +when invoked with "ls --color", so if your terminal can support colors +in "ls --color", it will support "emacs --color" as well. See the +user manual for the possible values of the MODE parameter. + +*** Emacs now supports several character terminals which provide more +than 8 colors. For example, for `xterm', 16-color, 88-color, and +256-color modes are supported. Emacs automatically notes at startup +the extended number of colors, and defines the appropriate entries for +all of these colors. + +*** Emacs now uses the full range of available colors for the default +faces when running on a color terminal, including 16-, 88-, and +256-color xterms. This means that when you run "emacs -nw" on an +88-color or 256-color xterm, you will see essentially the same face +colors as on X. + +*** There's a new support for colors on `rxvt' terminal emulator. + +** ebnf2ps changes: + +*** New option `ebnf-arrow-extra-width' which specify extra width for arrow +shape drawing. +The extra width is used to avoid that the arrowhead and the terminal border +overlap. It depends on `ebnf-arrow-shape' and `ebnf-line-width'. + +*** New option `ebnf-arrow-scale' which specify the arrow scale. +Values lower than 1.0, shrink the arrow. +Values greater than 1.0, expand the arrow. + +* New Modes and Packages in Emacs 22.1 + +** CUA mode is now part of the Emacs distribution. + +The new cua package provides CUA-like keybindings using C-x for +cut (kill), C-c for copy, C-v for paste (yank), and C-z for undo. +With cua, the region can be set and extended using shifted movement +keys (like pc-selection-mode) and typed text replaces the active +region (like delete-selection-mode). Do not enable these modes with +cua-mode. Customize the variable `cua-mode' to enable cua. + +The cua-selection-mode enables the CUA keybindings for the region but +does not change the bindings for C-z/C-x/C-c/C-v. It can be used as a +replacement for pc-selection-mode. + +In addition, cua provides unified rectangle support with visible +rectangle highlighting: Use C-return to start a rectangle, extend it +using the movement commands (or mouse-3), and cut or copy it using C-x +or C-c (using C-w and M-w also works). + +Use M-o and M-c to `open' or `close' the rectangle, use M-b or M-f, to +fill it with blanks or another character, use M-u or M-l to upcase or +downcase the rectangle, use M-i to increment the numbers in the +rectangle, use M-n to fill the rectangle with a numeric sequence (such +as 10 20 30...), use M-r to replace a regexp in the rectangle, and use +M-' or M-/ to restrict command on the rectangle to a subset of the +rows. See the commentary in cua-base.el for more rectangle commands. + +Cua also provides unified support for registers: Use a numeric +prefix argument between 0 and 9, i.e. M-0 .. M-9, for C-x, C-c, and +C-v to cut or copy into register 0-9, or paste from register 0-9. + +The last text deleted (not killed) is automatically stored in +register 0. This includes text deleted by typing text. + +Finally, cua provides a global mark which is set using S-C-space. +When the global mark is active, any text which is cut or copied is +automatically inserted at the global mark position. See the +commentary in cua-base.el for more global mark related commands. + +The features of cua also works with the standard Emacs bindings for +kill, copy, yank, and undo. If you want to use cua mode, but don't +want the C-x, C-c, C-v, and C-z bindings, you can customize the +`cua-enable-cua-keys' variable. + +Note: This version of cua mode is not backwards compatible with older +versions of cua.el and cua-mode.el. To ensure proper operation, you +must remove older versions of cua.el or cua-mode.el as well as the +loading and customization of those packages from the .emacs file. + +** Tramp is now part of the distribution. + +This package is similar to Ange-FTP: it allows you to edit remote +files. But whereas Ange-FTP uses FTP to access the remote host, +Tramp uses a shell connection. The shell connection is always used +for filename completion and directory listings and suchlike, but for +the actual file transfer, you can choose between the so-called +`inline' methods (which transfer the files through the shell +connection using base64 or uu encoding) and the `out-of-band' methods +(which invoke an external copying program such as `rcp' or `scp' or +`rsync' to do the copying). + +Shell connections can be acquired via `rsh', `ssh', `telnet' and also +`su' and `sudo'. Ange-FTP is still supported via the `ftp' method. + +If you want to disable Tramp you should set + + (setq tramp-default-method "ftp") + +Removing Tramp, and re-enabling Ange-FTP, can be achieved by M-x +tramp-unload-tramp. + +** The image-dired.el package allows you to easily view, tag and in +other ways manipulate image files and their thumbnails, using dired as +the main interface. Image-Dired provides functionality to generate +simple image galleries. + +** Image files are normally visited in Image mode, which lets you toggle +between viewing the image and viewing the text using C-c C-c. + +** The new python.el package is used to edit Python and Jython programs. + +** The URL package (which had been part of W3) is now part of Emacs. + +** Calc is now part of the Emacs distribution. + +Calc is an advanced desk calculator and mathematical tool written in +Emacs Lisp. The prefix for Calc has been changed to `C-x *' and Calc +can be started with `C-x * *'. The Calc manual is separate from the +Emacs manual; within Emacs, type "C-h i m calc RET" to read the +manual. A reference card is available in `etc/calccard.tex' and +`etc/calccard.ps'. + +** Org mode is now part of the Emacs distribution + +Org mode is a mode for keeping notes, maintaining ToDo lists, and +doing project planning with a fast and effective plain-text system. +It also contains a plain-text table editor with spreadsheet-like +capabilities. + +The Org mode table editor can be integrated into any major mode by +activating the minor Orgtbl-mode. + +The documentation for org-mode is in a separate manual; within Emacs, +type "C-h i m org RET" to read that manual. A reference card is +available in `etc/orgcard.tex' and `etc/orgcard.ps'. + +** ERC is now part of the Emacs distribution. + +ERC is a powerful, modular, and extensible IRC client for Emacs. + +To see what modules are available, type +M-x customize-option erc-modules RET. + +To start an IRC session with ERC, type M-x erc, and follow the prompts +for server, port, and nick. + +** Rcirc is now part of the Emacs distribution. + +Rcirc is an Internet relay chat (IRC) client. It supports +simultaneous connections to multiple IRC servers. Each discussion +takes place in its own buffer. For each connection you can join +several channels (many-to-many) and participate in private +(one-to-one) chats. Both channel and private chats are contained in +separate buffers. + +To start an IRC session using the default parameters, type M-x irc. +If you type C-u M-x irc, it prompts you for the server, nick, port and +startup channel parameters before connecting. + +** The new package ibuffer provides a powerful, completely +customizable replacement for buff-menu.el. + +** Newsticker is now part of the Emacs distribution. + +Newsticker asynchronously retrieves headlines (RSS) from a list of news +sites, prepares these headlines for reading, and allows for loading the +corresponding articles in a web browser. Its documentation is in a +separate manual. + +** The wdired.el package allows you to use normal editing commands on Dired +buffers to change filenames, permissions, etc... + +** Ido mode is now part of the Emacs distribution. + +The ido (interactively do) package is an extension of the iswitchb +package to do interactive opening of files and directories in addition +to interactive buffer switching. Ido is a superset of iswitchb (with +a few exceptions), so don't enable both packages. + +** The new global minor mode `file-name-shadow-mode' modifies the way +filenames being entered by the user in the minibuffer are displayed, so +that it's clear when part of the entered filename will be ignored due to +Emacs' filename parsing rules. The ignored portion can be made dim, +invisible, or otherwise less visually noticeable. The display method can +be displayed by customizing the variable `file-name-shadow-properties'. + +** Emacs' keyboard macro facilities have been enhanced by the new +kmacro package. + +Keyboard macros are now defined and executed via the F3 and F4 keys: +F3 starts a macro, F4 ends the macro, and pressing F4 again executes +the last macro. While defining the macro, F3 inserts a counter value +which automatically increments every time the macro is executed. + +There is now a keyboard macro ring which stores the most recently +defined macros. + +The C-x C-k sequence is now a prefix for the kmacro keymap which +defines bindings for moving through the keyboard macro ring, +C-x C-k C-p and C-x C-k C-n, editing the last macro C-x C-k C-e, +manipulating the macro counter and format via C-x C-k C-c, +C-x C-k C-a, and C-x C-k C-f. See the commentary in kmacro.el +for more commands. + +The original macro bindings C-x (, C-x ), and C-x e are still +available, but they now interface to the keyboard macro ring too. + +The C-x e command now automatically terminates the current macro +before calling it, if used while defining a macro. + +In addition, when ending or calling a macro with C-x e, the macro can +be repeated immediately by typing just the `e'. You can customize +this behavior via the variables kmacro-call-repeat-key and +kmacro-call-repeat-with-arg. + +Keyboard macros can now be debugged and edited interactively. +C-x C-k SPC steps through the last keyboard macro one key sequence +at a time, prompting for the actions to take. + +** The new keypad setup package provides several common bindings for +the numeric keypad which is available on most keyboards. The numeric +keypad typically has the digits 0 to 9, a decimal point, keys marked ++, -, /, and *, an Enter key, and a NumLock toggle key. The keypad +package only controls the use of the digit and decimal keys. + +By customizing the variables `keypad-setup', `keypad-shifted-setup', +`keypad-numlock-setup', and `keypad-numlock-shifted-setup', or by +using the function `keypad-setup', you can rebind all digit keys and +the decimal key of the keypad in one step for each of the four +possible combinations of the Shift key state (not pressed/pressed) and +the NumLock toggle state (off/on). + +The choices for the keypad keys in each of the above states are: +`Plain numeric keypad' where the keys generates plain digits, +`Numeric keypad with decimal key' where the character produced by the +decimal key can be customized individually (for internationalization), +`Numeric Prefix Arg' where the keypad keys produce numeric prefix args +for Emacs editing commands, `Cursor keys' and `Shifted Cursor keys' +where the keys work like (shifted) arrow keys, home/end, etc., and +`Unspecified/User-defined' where the keypad keys (kp-0, kp-1, etc.) +are left unspecified and can be bound individually through the global +or local keymaps. + +** The printing package is now part of the Emacs distribution. + +If you enable the printing package by including (require 'printing) in +the .emacs file, the normal Print item on the File menu is replaced +with a Print sub-menu which allows you to preview output through +ghostview, use ghostscript to print (if you don't have a PostScript +printer) or send directly to printer a PostScript code generated by +`ps-print' package. Use M-x pr-help for more information. + +** The new package longlines.el provides a minor mode for editing text +files composed of long lines, based on the `use-hard-newlines' +mechanism. The long lines are broken up by inserting soft newlines, +which are automatically removed when saving the file to disk or +copying into the kill ring, clipboard, etc. By default, Longlines +mode inserts soft newlines automatically during editing, a behavior +referred to as "soft word wrap" in other text editors. This is +similar to Refill mode, but more reliable. To turn the word wrap +feature off, set `longlines-auto-wrap' to nil. + +** SES mode (ses-mode) is a new major mode for creating and editing +spreadsheet files. Besides the usual Emacs features (intuitive command +letters, undo, cell formulas in Lisp, plaintext files, etc.) it also offers +viral immunity and import/export of tab-separated values. + +** The new package table.el implements editable, WYSIWYG, embedded +`text tables' in Emacs buffers. It simulates the effect of putting +these tables in a special major mode. The package emulates WYSIWYG +table editing available in modern word processors. The package also +can generate a table source in typesetting and markup languages such +as latex and html from the visually laid out text table. + +** Filesets are collections of files. You can define a fileset in +various ways, such as based on a directory tree or based on +program files that include other program files. + +Once you have defined a fileset, you can perform various operations on +all the files in it, such as visiting them or searching and replacing +in them. + +** The minor mode Reveal mode makes text visible on the fly as you +move your cursor into hidden regions of the buffer. +It should work with any package that uses overlays to hide parts +of a buffer, such as outline-minor-mode, hs-minor-mode, hide-ifdef-mode, ... + +There is also Global Reveal mode which affects all buffers. + +** New minor mode, Visible mode, toggles invisibility in the current buffer. +When enabled, it makes all invisible text visible. When disabled, it +restores the previous value of `buffer-invisibility-spec'. + +** The new package flymake.el does on-the-fly syntax checking of program +source files. See the Flymake's Info manual for more details. + +** savehist saves minibuffer histories between sessions. +To use this feature, turn on savehist-mode in your `.emacs' file. + +** The ruler-mode.el library provides a minor mode for displaying an +"active" ruler in the header line. You can use the mouse to visually +change the `fill-column', `window-margins' and `tab-stop-list' +settings. + +** The file t-mouse.el is now part of Emacs and provides access to mouse +events from the console. It still requires gpm to work but has been updated +for Emacs 22. In particular, the mode-line is now position sensitive. + +** The new package scroll-lock.el provides the Scroll Lock minor mode +for pager-like scrolling. Keys which normally move point by line or +paragraph will scroll the buffer by the respective amount of lines +instead and point will be kept vertically fixed relative to window +boundaries during scrolling. + +** The new global minor mode `size-indication-mode' (off by default) +shows the size of accessible part of the buffer on the mode line. + +** The new package conf-mode.el handles thousands of configuration files, with +varying syntaxes for comments (;, #, //, /* */ or !), assignment (var = value, +var : value, var value or keyword var value) and sections ([section] or +section { }). Many files under /etc/, or with suffixes like .cf through +.config, .properties (Java), .desktop (KDE/Gnome), .ini and many others are +recognized. + +** GDB-Script-mode is used for files like .gdbinit. + +** The new package dns-mode.el adds syntax highlighting of DNS master files. +It is a modern replacement for zone-mode.el, which is now obsolete. + +** `cfengine-mode' is a major mode for editing GNU Cfengine +configuration files. + +** The TCL package tcl-mode.el was replaced by tcl.el. +This was actually done in Emacs-21.1, and was not documented. + +* Changes in Specialized Modes and Packages in Emacs 22.1: + +** Changes in Dired + +*** Bindings for Image-Dired added. +Several new keybindings, all starting with the C-t prefix, have been +added to Dired. They are all bound to commands in Image-Dired. As a +starting point, mark some image files in a dired buffer and do C-t d +to display thumbnails of them in a separate buffer. + +** Info mode changes + +*** Images in Info pages are supported. + +Info pages show embedded images, in Emacs frames with image support. +Info documentation that includes images, processed with makeinfo +version 4.7 or newer, compiles to Info pages with embedded images. + +*** `Info-index' offers completion. + +*** http and ftp links in Info are now operational: they look like cross +references and following them calls `browse-url'. + +*** isearch in Info uses Info-search and searches through multiple nodes. + +Before leaving the initial Info node isearch fails once with the error +message [initial node], and with subsequent C-s/C-r continues through +other nodes. When isearch fails for the rest of the manual, it wraps +around the whole manual to the top/final node. The user option +`Info-isearch-search' controls whether to use Info-search for isearch, +or the default isearch search function that wraps around the current +Info node. + +*** New search commands: `Info-search-case-sensitively' (bound to S), +`Info-search-backward', and `Info-search-next' which repeats the last +search without prompting for a new search string. + +*** New command `info-apropos' searches the indices of the known +Info files on your system for a string, and builds a menu of the +possible matches. + +*** New command `Info-history-forward' (bound to r and new toolbar icon) +moves forward in history to the node you returned from after using +`Info-history-back' (renamed from `Info-last'). + +*** New command `Info-history' (bound to L) displays a menu of visited nodes. + +*** New command `Info-toc' (bound to T) creates a node with table of contents +from the tree structure of menus of the current Info file. + +*** New command `Info-copy-current-node-name' (bound to w) copies +the current Info node name into the kill ring. With a zero prefix +arg, puts the node name inside the `info' function call. + +*** New face `info-xref-visited' distinguishes visited nodes from unvisited +and a new option `Info-fontify-visited-nodes' to control this. + +*** A numeric prefix argument of `info' selects an Info buffer +with the number appended to the `*info*' buffer name (e.g. "*info*<2>"). + +*** Info now hides node names in menus and cross references by default. + +If you prefer the old behavior, you can set the new user option +`Info-hide-note-references' to nil. + +*** The default value for `Info-scroll-prefer-subnodes' is now nil. + +** Emacs server changes + +*** You can have several Emacs servers on the same machine. + + % emacs --eval '(setq server-name "foo")' -f server-start & + % emacs --eval '(setq server-name "bar")' -f server-start & + % emacsclient -s foo file1 + % emacsclient -s bar file2 + +*** The `emacsclient' command understands the options `--eval' and +`--display' which tell Emacs respectively to evaluate the given Lisp +expression and to use the given display when visiting files. + +*** User option `server-mode' can be used to start a server process. + +** Locate changes + +*** By default, reverting the *Locate* buffer now just runs the last +`locate' command back over again without offering to update the locate +database (which normally only works if you have root privileges). If +you prefer the old behavior, set the new customizable option +`locate-update-when-revert' to t. + +** Desktop package + +*** Desktop saving is now a minor mode, `desktop-save-mode'. + +*** The variable `desktop-enable' is obsolete. + +Customize `desktop-save-mode' to enable desktop saving. + +*** Buffers are saved in the desktop file in the same order as that in the +buffer list. + +*** The desktop package can be customized to restore only some buffers +immediately, remaining buffers are restored lazily (when Emacs is +idle). + +*** New command line option --no-desktop + +*** New commands: + - desktop-revert reverts to the last loaded desktop. + - desktop-change-dir kills current desktop and loads a new. + - desktop-save-in-desktop-dir saves desktop in the directory from which + it was loaded. + - desktop-lazy-complete runs the desktop load to completion. + - desktop-lazy-abort aborts lazy loading of the desktop. + +*** New customizable variables: + - desktop-save. Determines whether the desktop should be saved when it is + killed. + - desktop-file-name-format. Format in which desktop file names should be saved. + - desktop-path. List of directories in which to lookup the desktop file. + - desktop-locals-to-save. List of local variables to save. + - desktop-globals-to-clear. List of global variables that `desktop-clear' will clear. + - desktop-clear-preserve-buffers-regexp. Regexp identifying buffers that `desktop-clear' + should not delete. + - desktop-restore-eager. Number of buffers to restore immediately. Remaining buffers are + restored lazily (when Emacs is idle). + - desktop-lazy-verbose. Verbose reporting of lazily created buffers. + - desktop-lazy-idle-delay. Idle delay before starting to create buffers. + +*** New hooks: + - desktop-after-read-hook run after a desktop is loaded. + - desktop-no-desktop-file-hook run when no desktop file is found. + +** Recentf changes + +The recent file list is now automatically cleaned up when recentf mode is +enabled. The new option `recentf-auto-cleanup' controls when to do +automatic cleanup. + +The ten most recent files can be quickly opened by using the shortcut +keys 1 to 9, and 0, when the recent list is displayed in a buffer via +the `recentf-open-files', or `recentf-open-more-files' commands. + +The `recentf-keep' option replaces `recentf-keep-non-readable-files-p' +and provides a more general mechanism to customize which file names to +keep in the recent list. + +With the more advanced option `recentf-filename-handlers', you can +specify functions that successively transform recent file names. For +example, if set to `file-truename' plus `abbreviate-file-name', the +same file will not be in the recent list with different symbolic +links, and the file name will be abbreviated. + +To follow naming convention, `recentf-menu-append-commands-flag' +replaces the misnamed option `recentf-menu-append-commands-p'. The +old name remains available as alias, but has been marked obsolete. + +** Auto-Revert changes + +*** You can now use Auto Revert mode to `tail' a file. + +If point is at the end of a file buffer before reverting, Auto Revert +mode keeps it at the end after reverting. Similarly if point is +displayed at the end of a file buffer in any window, it stays at the end +of the buffer in that window. This allows you to "tail" a file: just +put point at the end of the buffer and it stays there. This rule +applies to file buffers. For non-file buffers, the behavior can be mode +dependent. + +If you are sure that the file will only change by growing at the end, +then you can tail the file more efficiently by using the new minor +mode Auto Revert Tail mode. The function `auto-revert-tail-mode' +toggles this mode. + +*** Auto Revert mode is now more careful to avoid excessive reverts and +other potential problems when deciding which non-file buffers to +revert. This matters especially if Global Auto Revert mode is enabled +and `global-auto-revert-non-file-buffers' is non-nil. Auto Revert +mode only reverts a non-file buffer if the buffer has a non-nil +`revert-buffer-function' and a non-nil `buffer-stale-function', which +decides whether the buffer should be reverted. Currently, this means +that auto reverting works for Dired buffers (although this may not +work properly on all operating systems) and for the Buffer Menu. + +*** If the new user option `auto-revert-check-vc-info' is non-nil, Auto +Revert mode reliably updates version control info (such as the version +control number in the mode line), in all version controlled buffers in +which it is active. If the option is nil, the default, then this info +only gets updated whenever the buffer gets reverted. + +** Changes in Shell Mode + +*** Shell output normally scrolls so that the input line is at the +bottom of the window -- thus showing the maximum possible text. (This +is similar to the way sequential output to a terminal works.) + +** Changes in Hi Lock + +*** hi-lock-mode now only affects a single buffer, and a new function +`global-hi-lock-mode' enables Hi Lock in all buffers. By default, if +hi-lock-mode is used in what appears to be the initialization file, a +warning message suggests to use global-hi-lock-mode instead. However, +if the new variable `hi-lock-archaic-interface-deduce' is non-nil, +using hi-lock-mode in an initialization file will turn on Hi Lock in all +buffers and no warning will be issued (for compatibility with the +behavior in older versions of Emacs). + +** Changes in Allout + +*** Topic cryptography added, enabling easy gpg topic encryption and +decryption. Per-topic basis enables interspersing encrypted-text and +clear-text within a single file to your heart's content, using symmetric +and/or public key modes. Time-limited key caching, user-provided +symmetric key hinting and consistency verification, auto-encryption of +pending topics on save, and more, make it easy to use encryption in +powerful ways. Encryption behavior customization is collected in the +allout-encryption customization group. + +*** Default command prefix was changed to "\C-c " (control-c space), to +avoid intruding on user's keybinding space. Customize the +`allout-command-prefix' variable to your preference. + +*** Some previously rough topic-header format edge cases are reconciled. +Level 1 topics use the mode's comment format, and lines starting with the +asterisk - for instance, the comment close of some languages (eg, c's "*/" +or mathematica's "*)") - at the beginning of line are no longer are +interpreted as level 1 topics in those modes. + +*** Many or most commonly occurring "accidental" topics are disqualified. +Text in item bodies that looks like a low-depth topic is no longer mistaken +for one unless its first offspring (or that of its next sibling with +offspring) is only one level deeper. + +For example, pasting some text with a bunch of leading asterisks into a +topic that's followed by a level 3 or deeper topic will not cause the +pasted text to be mistaken for outline structure. + +The same constraint is applied to any level 2 or 3 topics. + +This settles an old issue where typed or pasted text needed to be carefully +reviewed, and sometimes doctored, to avoid accidentally disrupting the +outline structure. Now that should be generally unnecessary, as the most +prone-to-occur accidents are disqualified. + +*** Allout now refuses to create "containment discontinuities", where a +topic is shifted deeper than the offspring-depth of its container. On the +other hand, allout now operates gracefully with existing containment +discontinuities, revealing excessively contained topics rather than either +leaving them hidden or raising an error. + +*** Navigation within an item is easier. Repeated beginning-of-line and +end-of-line key commands (usually, ^A and ^E) cycle through the +beginning/end-of-line and then beginning/end of topic, etc. See new +customization vars `allout-beginning-of-line-cycles' and +`allout-end-of-line-cycles'. + +*** New or revised allout-mode activity hooks enable creation of +cooperative enhancements to allout mode without changes to the mode, +itself. + +See `allout-exposure-change-hook', `allout-structure-added-hook', +`allout-structure-deleted-hook', and `allout-structure-shifted-hook'. + +`allout-exposure-change-hook' replaces the existing +`allout-view-change-hook', which is being deprecated. Both are still +invoked, but `allout-view-change-hook' will eventually be ignored. +`allout-exposure-change-hook' is called with explicit arguments detailing +the specifics of each change (as are the other new hooks), making it easier +to use than the old version. + +There is a new mode deactivation hook, `allout-mode-deactivate-hook', for +coordinating with deactivation of allout-mode. Both that and the mode +activation hook, `allout-mode-hook' are now run after the `allout-mode' +variable is changed, rather than before. + +*** Allout now uses text overlay's `invisible' property for concealed text, +instead of selective-display. This simplifies the code, in particular +avoiding the need for kludges for isearch dynamic-display, discretionary +handling of edits of concealed text, undo concerns, etc. + +*** There are many other fixes and refinements, including: + + - repaired inhibition of inadvertent edits to concealed text, without + inhibiting undo; we now reveal undo changes within concealed text. + - auto-fill-mode is now left inactive when allout-mode starts, if it + already was inactive. also, `allout-inhibit-auto-fill' custom + configuration variable makes it easy to disable auto fill in allout + outlines in general or on a per-buffer basis. + - allout now tolerates fielded text in outlines without disruption. + - hot-spot navigation now is modularized with a new function, + `allout-hotspot-key-handler', enabling easier use and enhancement of + the functionality in allout addons. + - repaired retention of topic body hanging indent upon topic depth shifts + - bulleting variation is simpler and more accommodating, both in the + default behavior and in ability to vary when creating new topics + - mode deactivation now does cleans up effectively, more properly + restoring affected variables and hooks to former state, removing + overlays, etc. see `allout-add-resumptions' and + `allout-do-resumptions', which replace the old `allout-resumptions'. + - included a few unit-tests for interior functionality. developers can + have them automatically run at the end of module load by customizing + the option `allout-run-unit-tests-on-load'. + - many, many other, more minor tweaks, fixes, and refinements. + - version number incremented to 2.2 + +** Hideshow mode changes + +*** New variable `hs-set-up-overlay' allows customization of the overlay +used to effect hiding for hideshow minor mode. Integration with isearch +handles the overlay property `display' specially, preserving it during +temporary overlay showing in the course of an isearch operation. + +*** New variable `hs-allow-nesting' non-nil means that hiding a block does +not discard the hidden state of any "internal" blocks; when the parent +block is later shown, the internal blocks remain hidden. Default is nil. + +** FFAP changes + +*** New ffap commands and keybindings: + +C-x C-r (`ffap-read-only'), +C-x C-v (`ffap-alternate-file'), C-x C-d (`ffap-list-directory'), +C-x 4 r (`ffap-read-only-other-window'), C-x 4 d (`ffap-dired-other-window'), +C-x 5 r (`ffap-read-only-other-frame'), C-x 5 d (`ffap-dired-other-frame'). + +*** FFAP accepts wildcards in a file name by default. + +C-x C-f passes the file name to `find-file' with non-nil WILDCARDS +argument, which visits multiple files, and C-x d passes it to `dired'. + +** Changes in Skeleton + +*** In skeleton.el, `-' marks the `skeleton-point' without interregion interaction. + +`@' has reverted to only setting `skeleton-positions' and no longer +sets `skeleton-point'. Skeletons which used @ to mark +`skeleton-point' independent of `_' should now use `-' instead. The +updated `skeleton-insert' docstring explains these new features along +with other details of skeleton construction. + +*** The variables `skeleton-transformation', `skeleton-filter', and +`skeleton-pair-filter' have been renamed to +`skeleton-transformation-function', `skeleton-filter-function', and +`skeleton-pair-filter-function'. The old names are still available +as aliases. + +** HTML/SGML changes + +*** Emacs now tries to set up buffer coding systems for HTML/XML files +automatically. + +*** SGML mode has indentation and supports XML syntax. +The new variable `sgml-xml-mode' tells SGML mode to use XML syntax. +When this option is enabled, SGML tags are inserted in XML style, +i.e., there is always a closing tag. +By default, its setting is inferred on a buffer-by-buffer basis +from the file name or buffer contents. + +*** The variable `sgml-transformation' has been renamed to +`sgml-transformation-function'. The old name is still available as +alias. + +*** `xml-mode' is now an alias for `sgml-mode', which has XML support. + +** TeX modes + +*** New major mode Doctex mode, for *.dtx files. + +*** C-c C-c prompts for a command to run, and tries to offer a good default. + +*** The user option `tex-start-options-string' has been replaced +by two new user options: `tex-start-options', which should hold +command-line options to feed to TeX, and `tex-start-commands' which should hold +TeX commands to use at startup. + +*** verbatim environments are now highlighted in courier by font-lock +and super/sub-scripts are made into super/sub-scripts. + +** RefTeX mode changes + +*** Changes to RefTeX's table of contents + +The new command keys "<" and ">" in the TOC buffer promote/demote the +section at point or all sections in the current region, with full +support for multifile documents. + +The new command `reftex-toc-recenter' (`C-c -') shows the current +section in the TOC buffer without selecting the TOC window. +Recentering can happen automatically in idle time when the option +`reftex-auto-recenter-toc' is turned on. The highlight in the TOC +buffer stays when the focus moves to a different window. A dedicated +frame can show the TOC with the current section always automatically +highlighted. The frame is created and deleted from the toc buffer +with the `d' key. + +The toc window can be split off horizontally instead of vertically. +See new option `reftex-toc-split-windows-horizontally'. + +Labels can be renamed globally from the table of contents using the +key `M-%'. + +The new command `reftex-goto-label' jumps directly to a label +location. + +*** Changes related to citations and BibTeX database files + +Commands that insert a citation now prompt for optional arguments when +called with a prefix argument. Related new options are +`reftex-cite-prompt-optional-args' and `reftex-cite-cleanup-optional-args'. + +The new command `reftex-create-bibtex-file' creates a BibTeX database +with all entries referenced in the current document. The keys "e" and +"E" allow to produce a BibTeX database file from entries marked in a +citation selection buffer. + +The command `reftex-citation' uses the word in the buffer before the +cursor as a default search string. + +The support for chapterbib has been improved. Different chapters can +now use BibTeX or an explicit `thebibliography' environment. + +The macros which specify the bibliography file (like \bibliography) +can be configured with the new option `reftex-bibliography-commands'. + +Support for jurabib has been added. + +*** Global index matched may be verified with a user function. + +During global indexing, a user function can verify an index match. +See new option `reftex-index-verify-function'. + +*** Parsing documents with many labels can be sped up. + +Operating in a document with thousands of labels can be sped up +considerably by allowing RefTeX to derive the type of a label directly +from the label prefix like `eq:' or `fig:'. The option +`reftex-trust-label-prefix' needs to be configured in order to enable +this feature. While the speed-up is significant, this may reduce the +quality of the context offered by RefTeX to describe a label. + +*** Miscellaneous changes + +The macros which input a file in LaTeX (like \input, \include) can be +configured in the new option `reftex-include-file-commands'. + +RefTeX supports global incremental search. + +** BibTeX mode + +*** The new command `bibtex-url' browses a URL for the BibTeX entry at +point (bound to C-c C-l and mouse-2, RET on clickable fields). + +*** The new command `bibtex-entry-update' (bound to C-c C-u) updates +an existing BibTeX entry by inserting fields that may occur but are not +present. + +*** New `bibtex-entry-format' option `required-fields', enabled by default. + +*** `bibtex-maintain-sorted-entries' can take values `plain', +`crossref', and `entry-class' which control the sorting scheme used +for BibTeX entries. `bibtex-sort-entry-class' controls the sorting +scheme `entry-class'. TAB completion for reference keys and +automatic detection of duplicates does not require anymore that +`bibtex-maintain-sorted-entries' is non-nil. + +*** The new command `bibtex-complete' completes word fragment before +point according to context (bound to M-tab). + +*** In BibTeX mode the command `fill-paragraph' (M-q) fills +individual fields of a BibTeX entry. + +*** The new variable `bibtex-autofill-types' contains a list of entry +types for which fields are filled automatically (if possible). + +*** The new commands `bibtex-find-entry' and `bibtex-find-crossref' +locate entries and crossref'd entries (bound to C-c C-s and C-c C-x). +Crossref fields are clickable (bound to mouse-2, RET). + +*** The new variables `bibtex-files' and `bibtex-file-path' define a set +of BibTeX files that are searched for entry keys. + +*** The new command `bibtex-validate-globally' checks for duplicate keys +in multiple BibTeX files. + +*** If the new variable `bibtex-autoadd-commas' is non-nil, +automatically add missing commas at end of BibTeX fields. + +*** The new command `bibtex-copy-summary-as-kill' pushes summary +of BibTeX entry to kill ring (bound to C-c C-t). + +*** If the new variable `bibtex-parse-keys-fast' is non-nil, +use fast but simplified algorithm for parsing BibTeX keys. + +*** The new variables bibtex-expand-strings and +bibtex-autokey-expand-strings control the expansion of strings when +extracting the content of a BibTeX field. + +*** The variables `bibtex-autokey-name-case-convert' and +`bibtex-autokey-titleword-case-convert' have been renamed to +`bibtex-autokey-name-case-convert-function' and +`bibtex-autokey-titleword-case-convert-function'. The old names are +still available as aliases. + +** GUD changes + +*** The new package gdb-ui.el provides an enhanced graphical interface to +GDB. You can interact with GDB through the GUD buffer in the usual way, but +there are also further buffers which control the execution and describe the +state of your program. It can separate the input/output of your program from +that of GDB and watches expressions in the speedbar. It also uses features of +Emacs 21/22 such as the toolbar, and bitmaps in the fringe to indicate +breakpoints. + +To use this package just type M-x gdb. See the Emacs manual if you want the +old behaviour. + +*** GUD mode has its own tool bar for controlling execution of the inferior +and other common debugger commands. + +*** In GUD mode, when talking to GDB, C-x C-a C-j "jumps" the program +counter to the specified source line (the one where point is). + +*** The variable tooltip-gud-tips-p has been removed. GUD tooltips can now be +toggled independently of normal tooltips with the minor mode +`gud-tooltip-mode'. + +*** In graphical mode, with a C program, GUD Tooltips have been extended to +display the #define directive associated with an identifier when program is +not executing. + +*** GUD mode improvements for jdb: + +**** Search for source files using jdb classpath and class information. +Fast startup since there is no need to scan all source files up front. +There is also no need to create and maintain lists of source +directories to scan. Look at `gud-jdb-use-classpath' and +`gud-jdb-classpath' customization variables documentation. + +**** The previous method of searching for source files has been +preserved in case someone still wants/needs to use it. +Set `gud-jdb-use-classpath' to nil. + +**** Supports the standard breakpoint (gud-break, gud-clear) +set/clear operations from Java source files under the classpath, stack +traversal (gud-up, gud-down), and run until current stack finish +(gud-finish). + +**** Supports new jdb (Java 1.2 and later) in addition to oldjdb +(Java 1.1 jdb). + +*** Added jdb Customization Variables + +**** `gud-jdb-command-name'. What command line to use to invoke jdb. + +**** `gud-jdb-use-classpath'. Allows selection of java source file searching +method: set to t for new method, nil to scan `gud-jdb-directories' for +java sources (previous method). + +**** `gud-jdb-directories'. List of directories to scan and search for Java +classes using the original gud-jdb method (if `gud-jdb-use-classpath' +is nil). + +*** Minor Improvements + +**** The STARTTLS wrapper (starttls.el) can now use GNUTLS +instead of the OpenSSL based `starttls' tool. For backwards +compatibility, it prefers `starttls', but you can toggle +`starttls-use-gnutls' to switch to GNUTLS (or simply remove the +`starttls' tool). + +**** Do not allow debugger output history variable to grow without bounds. + +** Lisp mode changes + +*** Lisp mode now uses `font-lock-doc-face' for doc strings. + +*** C-u C-M-q in Emacs Lisp mode pretty-prints the list after point. + +*** New features in evaluation commands + +**** The function `eval-defun' (C-M-x) called on defface reinitializes +the face to the value specified in the defface expression. + +**** Typing C-x C-e twice prints the value of the integer result +in additional formats (octal, hexadecimal, character) specified +by the new function `eval-expression-print-format'. The same +function also defines the result format for `eval-expression' (M-:), +`eval-print-last-sexp' (C-j) and some edebug evaluation functions. + +** Changes to cmuscheme + +*** Emacs now offers to start Scheme if the user tries to +evaluate a Scheme expression but no Scheme subprocess is running. + +*** If the file ~/.emacs_NAME or ~/.emacs.d/init_NAME.scm (where NAME +is the name of the Scheme interpreter) exists, its contents are sent +to the Scheme subprocess upon startup. + +*** There are new commands to instruct the Scheme interpreter to trace +procedure calls (`scheme-trace-procedure') and to expand syntactic forms +(`scheme-expand-current-form'). The commands actually sent to the Scheme +subprocess are controlled by the user options `scheme-trace-command', +`scheme-untrace-command' and `scheme-expand-current-form'. + +** Ewoc changes + +*** The new function `ewoc-delete' deletes specified nodes. + +*** `ewoc-create' now takes optional arg NOSEP, which inhibits insertion of +a newline after each pretty-printed entry and after the header and footer. +This allows you to create multiple-entry ewocs on a single line and to +effect "invisible" nodes by arranging for the pretty-printer to not print +anything for those nodes. + +For example, these two sequences of expressions behave identically: + +;; NOSEP nil +(defun PP (data) (insert (format "%S" data))) +(ewoc-create 'PP "start\n") + +;; NOSEP t +(defun PP (data) (insert (format "%S\n" data))) +(ewoc-create 'PP "start\n\n" "\n" t) + +** CC mode changes + +*** The CC Mode manual has been extensively revised. +The information about using CC Mode has been separated from the larger +and more difficult chapters about configuration. + +*** New Minor Modes +**** Electric Minor Mode toggles the electric action of non-alphabetic keys. +The new command c-toggle-electric-mode is bound to C-c C-l. Turning the +mode off can be helpful for editing chaotically indented code and for +users new to CC Mode, who sometimes find electric indentation +disconcerting. Its current state is displayed in the mode line with an +'l', e.g. "C/al". + +**** Subword Minor Mode makes Emacs recognize word boundaries at upper case +letters in StudlyCapsIdentifiers. You enable this feature by C-c C-w. It can +also be used in non-CC Mode buffers. :-) Contributed by Masatake YAMATO. + +*** Support for the AWK language. +Support for the AWK language has been introduced. The implementation is +based around GNU AWK version 3.1, but it should work pretty well with +any AWK. As yet, not all features of CC Mode have been adapted for AWK. +Here is a summary: + +**** Indentation Engine +The CC Mode indentation engine fully supports AWK mode. + +AWK mode handles code formatted in the conventional AWK fashion: `{'s +which start actions, user-defined functions, or compound statements are +placed on the same line as the associated construct; the matching `}'s +are normally placed under the start of the respective pattern, function +definition, or structured statement. + +The predefined line-up functions haven't yet been adapted for AWK +mode, though some of them may work serendipitously. There shouldn't +be any problems writing custom indentation functions for AWK mode. + +**** Font Locking +There is a single level of font locking in AWK mode, rather than the +three distinct levels the other modes have. There are several +idiosyncrasies in AWK mode's font-locking due to the peculiarities of +the AWK language itself. + +**** Comment and Movement Commands +These commands all work for AWK buffers. The notion of "defun" has +been augmented to include AWK pattern-action pairs - the standard +"defun" commands on key sequences C-M-a, C-M-e, and C-M-h use this +extended definition. + +**** "awk" style, Auto-newline Insertion and Clean-ups +A new style, "awk" has been introduced, and this is now the default +style for AWK code. With auto-newline enabled, the clean-up +c-one-liner-defun (see above) is useful. + +*** Font lock support. +CC Mode now provides font lock support for all its languages. This +supersedes the font lock patterns that have been in the core font lock +package for C, C++, Java and Objective-C. Like indentation, font +locking is done in a uniform way across all languages (except the new +AWK mode - see below). That means that the new font locking will be +different from the old patterns in various details for most languages. + +The main goal of the font locking in CC Mode is accuracy, to provide a +dependable aid in recognizing the various constructs. Some, like +strings and comments, are easy to recognize while others like +declarations and types can be very tricky. CC Mode can go to great +lengths to recognize declarations and casts correctly, especially when +the types aren't recognized by standard patterns. This is a fairly +demanding analysis which can be slow on older hardware, and it can +therefore be disabled by choosing a lower decoration level with the +variable font-lock-maximum-decoration. + +Note that the most demanding font lock level has been tuned with lazy +fontification in mind; Just-In-Time-Lock mode should be enabled for +the highest font lock level (by default, it is). Fontifying a file +with several thousand lines in one go can take the better part of a +minute. + +**** The (c|c++|objc|java|idl|pike)-font-lock-extra-types variables +are now used by CC Mode to recognize identifiers that are certain to +be types. (They are also used in cases that aren't related to font +locking.) At the maximum decoration level, types are often recognized +properly anyway, so these variables should be fairly restrictive and +not contain patterns for uncertain types. + +**** Support for documentation comments. +There is a "plugin" system to fontify documentation comments like +Javadoc and the markup within them. It's independent of the host +language, so it's possible to e.g. turn on Javadoc font locking in C +buffers. See the variable c-doc-comment-style for details. + +Currently three kinds of doc comment styles are recognized: Sun's +Javadoc, Autodoc (which is used in Pike) and GtkDoc (used in C). (The +last was contributed by Masatake YAMATO). This is by no means a +complete list of the most common tools; if your doc comment extractor +of choice is missing then please drop a note to bug-cc-mode@gnu.org. + +**** Better handling of C++ templates. +As a side effect of the more accurate font locking, C++ templates are +now handled much better. The angle brackets that delimit them are +given parenthesis syntax so that they can be navigated like other +parens. + +This also improves indentation of templates, although there still is +work to be done in that area. E.g. it's required that multiline +template clauses are written in full and then refontified to be +recognized, and the indentation of nested templates is a bit odd and +not as configurable as it ought to be. + +**** Improved handling of Objective-C and CORBA IDL. +Especially the support for Objective-C and IDL has gotten an overhaul. +The special "@" declarations in Objective-C are handled correctly. +All the keywords used in CORBA IDL, PSDL, and CIDL are recognized and +handled correctly, also wrt indentation. + +*** Changes in Key Sequences +**** c-toggle-auto-hungry-state is no longer bound to C-c C-t. + +**** c-toggle-hungry-state is no longer bound to C-c C-d. +This binding has been taken over by c-hungry-delete-forwards. + +**** c-toggle-auto-state (C-c C-t) has been renamed to c-toggle-auto-newline. +c-toggle-auto-state remains as an alias. + +**** The new commands c-hungry-backspace and c-hungry-delete-forwards +have key bindings C-c C-DEL (or C-c DEL, for the benefit of TTYs) and +C-c C-d (or C-c C- or C-c ) respectively. These +commands delete entire blocks of whitespace with a single +key-sequence. [N.B. "DEL" is the key.] + +**** The new command c-toggle-electric-mode is bound to C-c C-l. + +**** The new command c-subword-mode is bound to C-c C-w. + +*** C-c C-s (`c-show-syntactic-information') now highlights the anchor +position(s). + +*** New syntactic symbols in IDL mode. +The top level constructs "module" and "composition" (from CIDL) are +now handled like "namespace" in C++: They are given syntactic symbols +module-open, module-close, inmodule, composition-open, +composition-close, and incomposition. + +*** New functions to do hungry delete without enabling hungry delete mode. +The new functions `c-hungry-backspace' and `c-hungry-delete-forward' +provide hungry deletion without having to toggle a mode. They are +bound to C-c C-DEL and C-c C-d (and several variants, for the benefit +of different keyboard setups. See "Changes in key sequences" above). + +*** Better control over `require-final-newline'. + +The variable `c-require-final-newline' specifies which of the modes +implemented by CC mode should insert final newlines. Its value is a +list of modes, and only those modes should do it. By default the list +includes C, C++ and Objective-C modes. + +Whichever modes are in this list will set `require-final-newline' +based on `mode-require-final-newline'. + +*** Format change for syntactic context elements. + +The elements in the syntactic context returned by `c-guess-basic-syntax' +and stored in `c-syntactic-context' has been changed somewhat to allow +attaching more information. They are now lists instead of single cons +cells. E.g. a line that previously had the syntactic analysis + +((inclass . 11) (topmost-intro . 13)) + +is now analyzed as + +((inclass 11) (topmost-intro 13)) + +In some cases there are more than one position given for a syntactic +symbol. + +This change might affect code that calls `c-guess-basic-syntax' +directly, and custom lineup functions if they use +`c-syntactic-context'. However, the argument given to lineup +functions is still a single cons cell with nil or an integer in the +cdr. + +*** API changes for derived modes. + +There have been extensive changes "under the hood" which can affect +derived mode writers. Some of these changes are likely to cause +incompatibilities with existing derived modes, but on the other hand +care has now been taken to make it possible to extend and modify CC +Mode with less risk of such problems in the future. + +**** New language variable system. +These are variables whose values vary between CC Mode's different +languages. See the comment blurb near the top of cc-langs.el. + +**** New initialization functions. +The initialization procedure has been split up into more functions to +give better control: `c-basic-common-init', `c-font-lock-init', and +`c-init-language-vars'. + +*** Changes in analysis of nested syntactic constructs. +The syntactic analysis engine has better handling of cases where +several syntactic constructs appear nested on the same line. They are +now handled as if each construct started on a line of its own. + +This means that CC Mode now indents some cases differently, and +although it's more consistent there might be cases where the old way +gave results that's more to one's liking. So if you find a situation +where you think that the indentation has become worse, please report +it to bug-cc-mode@gnu.org. + +**** New syntactic symbol substatement-label. +This symbol is used when a label is inserted between a statement and +its substatement. E.g: + + if (x) + x_is_true: + do_stuff(); + +*** Better handling of multiline macros. + +**** Syntactic indentation inside macros. +The contents of multiline #define's are now analyzed and indented +syntactically just like other code. This can be disabled by the new +variable `c-syntactic-indentation-in-macros'. A new syntactic symbol +`cpp-define-intro' has been added to control the initial indentation +inside `#define's. + +**** New lineup function `c-lineup-cpp-define'. + +Now used by default to line up macro continuation lines. The behavior +of this function closely mimics the indentation one gets if the macro +is indented while the line continuation backslashes are temporarily +removed. If syntactic indentation in macros is turned off, it works +much line `c-lineup-dont-change', which was used earlier, but handles +empty lines within the macro better. + +**** Automatically inserted newlines continues the macro if used within one. +This applies to the newlines inserted by the auto-newline mode, and to +`c-context-line-break' and `c-context-open-line'. + +**** Better alignment of line continuation backslashes. +`c-backslash-region' tries to adapt to surrounding backslashes. New +variable `c-backslash-max-column' puts a limit on how far out +backslashes can be moved. + +**** Automatic alignment of line continuation backslashes. +This is controlled by the new variable `c-auto-align-backslashes'. It +affects `c-context-line-break', `c-context-open-line' and newlines +inserted in Auto-Newline mode. + +**** Line indentation works better inside macros. +Regardless whether syntactic indentation and syntactic indentation +inside macros are enabled or not, line indentation now ignores the +line continuation backslashes. This is most noticeable when syntactic +indentation is turned off and there are empty lines (save for the +backslash) in the macro. + +*** indent-for-comment is more customizable. +The behavior of M-; (indent-for-comment) is now configurable through +the variable `c-indent-comment-alist'. The indentation behavior is +based on the preceding code on the line, e.g. to get two spaces after +#else and #endif but indentation to `comment-column' in most other +cases (something which was hardcoded earlier). + +*** New function `c-context-open-line'. +It's the open-line equivalent of `c-context-line-break'. + +*** New clean-ups + +**** `comment-close-slash'. +With this clean-up, a block (i.e. c-style) comment can be terminated by +typing a slash at the start of a line. + +**** `c-one-liner-defun' +This clean-up compresses a short enough defun (for example, an AWK +pattern/action pair) onto a single line. "Short enough" is configurable. + +*** New lineup functions + +**** `c-lineup-string-cont' +This lineup function lines up a continued string under the one it +continues. E.g: + +result = prefix + "A message " + "string."; <- c-lineup-string-cont + +**** `c-lineup-cascaded-calls' +Lines up series of calls separated by "->" or ".". + +**** `c-lineup-knr-region-comment' +Gives (what most people think is) better indentation of comments in +the "K&R region" between the function header and its body. + +**** `c-lineup-gcc-asm-reg' +Provides better indentation inside asm blocks. + +**** `c-lineup-argcont' +Lines up continued function arguments after the preceding comma. + +*** Added toggle for syntactic indentation. +The function `c-toggle-syntactic-indentation' can be used to toggle +syntactic indentation. + +*** Better caching of the syntactic context. +CC Mode caches the positions of the opening parentheses (of any kind) +of the lists surrounding the point. Those positions are used in many +places as anchor points for various searches. The cache is now +improved so that it can be reused to a large extent when the point is +moved. The less it moves, the less needs to be recalculated. + +The effect is that CC Mode should be fast most of the time even when +opening parens are hung (i.e. aren't in column zero). It's typically +only the first time after the point is moved far down in a complex +file that it'll take noticeable time to find out the syntactic +context. + +*** Statements are recognized in a more robust way. +Statements are recognized most of the time even when they occur in an +"invalid" context, e.g. in a function argument. In practice that can +happen when macros are involved. + +*** Improved the way `c-indent-exp' chooses the block to indent. +It now indents the block for the closest sexp following the point +whose closing paren ends on a different line. This means that the +point doesn't have to be immediately before the block to indent. +Also, only the block and the closing line is indented; the current +line is left untouched. + +** Changes in Makefile mode + +*** Makefile mode has submodes for automake, gmake, makepp, BSD make and imake. + +The former two couldn't be differentiated before, and the latter three +are new. Font-locking is robust now and offers new customizable +faces. + +*** The variable `makefile-query-one-target-method' has been renamed +to `makefile-query-one-target-method-function'. The old name is still +available as alias. + +** Sql changes + +*** The variable `sql-product' controls the highlighting of different +SQL dialects. This variable can be set globally via Customize, on a +buffer-specific basis via local variable settings, or for the current +session using the new SQL->Product submenu. (This menu replaces the +SQL->Highlighting submenu.) + +The following values are supported: + + ansi ANSI Standard (default) + db2 DB2 + informix Informix + ingres Ingres + interbase Interbase + linter Linter + ms Microsoft + mysql MySQL + oracle Oracle + postgres Postgres + solid Solid + sqlite SQLite + sybase Sybase + +The current product name will be shown on the mode line following the +SQL mode indicator. + +The technique of setting `sql-mode-font-lock-defaults' directly in +your `.emacs' will no longer establish the default highlighting -- Use +`sql-product' to accomplish this. + +ANSI keywords are always highlighted. + +*** The function `sql-add-product-keywords' can be used to add +font-lock rules to the product specific rules. For example, to have +all identifiers ending in `_t' under MS SQLServer treated as a type, +you would use the following line in your .emacs file: + + (sql-add-product-keywords 'ms + '(("\\<\\w+_t\\>" . font-lock-type-face))) + +*** Oracle support includes keyword highlighting for Oracle 9i. + +Most SQL and PL/SQL keywords are implemented. SQL*Plus commands are +highlighted in `font-lock-doc-face'. + +*** Microsoft SQLServer support has been significantly improved. + +Keyword highlighting for SqlServer 2000 is implemented. +sql-interactive-mode defaults to use osql, rather than isql, because +osql flushes its error stream more frequently. Thus error messages +are displayed when they occur rather than when the session is +terminated. + +If the username and password are not provided to `sql-ms', osql is +called with the `-E' command line argument to use the operating system +credentials to authenticate the user. + +*** Postgres support is enhanced. +Keyword highlighting of Postgres 7.3 is implemented. Prompting for +the username and the pgsql `-U' option is added. + +*** MySQL support is enhanced. +Keyword highlighting of MySql 4.0 is implemented. + +*** Imenu support has been enhanced to locate tables, views, indexes, +packages, procedures, functions, triggers, sequences, rules, and +defaults. + +*** Added SQL->Start SQLi Session menu entry which calls the +appropriate `sql-interactive-mode' wrapper for the current setting of +`sql-product'. + +*** sql.el supports the SQLite interpreter--call 'sql-sqlite'. + +** Fortran mode changes + +*** F90 mode and Fortran mode have support for `hs-minor-mode' (hideshow). +It cannot deal with every code format, but ought to handle a sizeable +majority. + +*** F90 mode and Fortran mode have new navigation commands +`f90-end-of-block', `f90-beginning-of-block', `f90-next-block', +`f90-previous-block', `fortran-end-of-block', +`fortran-beginning-of-block'. + +*** Fortran mode does more font-locking by default. Use level 3 +highlighting for the old default. + +*** Fortran mode has a new variable `fortran-directive-re'. +Adapt this to match the format of any compiler directives you use. +Lines that match are never indented, and are given distinctive font-locking. + +*** The new function `f90-backslash-not-special' can be used to change +the syntax of backslashes in F90 buffers. + +** Miscellaneous programming mode changes + +*** In sh-script, a continuation line is only indented if the backslash was +preceded by a SPC or a TAB. + +*** Perl mode has a new variable `perl-indent-continued-arguments'. + +*** The old Octave mode bindings C-c f and C-c i have been changed +to C-c C-f and C-c C-i. The C-c C-i subcommands now have duplicate +bindings on control characters--thus, C-c C-i C-b is the same as +C-c C-i b, and so on. + +*** Prolog mode has a new variable `prolog-font-lock-keywords' +to support use of font-lock. + +** VC Changes + +*** New backends for Subversion and Meta-CVS. + +*** The new variable `vc-cvs-global-switches' specifies switches that +are passed to any CVS command invoked by VC. + +These switches are used as "global options" for CVS, which means they +are inserted before the command name. For example, this allows you to +specify a compression level using the `-z#' option for CVS. + +*** The key C-x C-q only changes the read-only state of the buffer +(toggle-read-only). It no longer checks files in or out. + +We made this change because we held a poll and found that many users +were unhappy with the previous behavior. If you do prefer this +behavior, you can bind `vc-toggle-read-only' to C-x C-q in your +`.emacs' file: + + (global-set-key "\C-x\C-q" 'vc-toggle-read-only) + +The function `vc-toggle-read-only' will continue to exist. + +*** VC-Annotate mode enhancements + +In VC-Annotate mode, you can now use the following key bindings for +enhanced functionality to browse the annotations of past revisions, or +to view diffs or log entries directly from vc-annotate-mode: + + P: annotates the previous revision + N: annotates the next revision + J: annotates the revision at line + A: annotates the revision previous to line + D: shows the diff of the revision at line with its previous revision + L: shows the log of the revision at line + W: annotates the workfile (most up to date) version + +** pcl-cvs changes + +*** In pcl-cvs mode, there is a new `d y' command to view the diffs +between the local version of the file and yesterday's head revision +in the repository. + +*** In pcl-cvs mode, there is a new `d r' command to view the changes +anyone has committed to the repository since you last executed +`checkout', `update' or `commit'. That means using cvs diff options +-rBASE -rHEAD. + +** Diff changes + +*** M-x diff uses Diff mode instead of Compilation mode. + +*** Diff mode key bindings changed. + +These are the new bindings: + +C-c C-e diff-ediff-patch (old M-A) +C-c C-n diff-restrict-view (old M-r) +C-c C-r diff-reverse-direction (old M-R) +C-c C-u diff-context->unified (old M-U) +C-c C-w diff-refine-hunk (old C-c C-r) + +To convert unified to context format, use C-u C-c C-u. +In addition, C-c C-u now operates on the region +in Transient Mark mode when the mark is active. + +** EDiff changes. + +*** When comparing directories. +Typing D brings up a buffer that lists the differences between the contents of +directories. Now it is possible to use this buffer to copy the missing files +from one directory to another. + +*** When comparing files or buffers. +Typing the = key now offers to perform the word-by-word comparison of the +currently highlighted regions in an inferior Ediff session. If you answer 'n' +then it reverts to the old behavior and asks the user to select regions for +comparison. + +*** The new command `ediff-backup' compares a file with its most recent +backup using `ediff'. If you specify the name of a backup file, +`ediff-backup' compares it with the file of which it is a backup. + +** Etags changes. + +*** New regular expressions features + +**** New syntax for regular expressions, multi-line regular expressions. + +The syntax --ignore-case-regexp=/regex/ is now undocumented and retained +only for backward compatibility. The new equivalent syntax is +--regex=/regex/i. More generally, it is --regex=/TAGREGEX/TAGNAME/MODS, +where `/TAGNAME' is optional, as usual, and MODS is a string of 0 or +more characters among `i' (ignore case), `m' (multi-line) and `s' +(single-line). The `m' and `s' modifiers behave as in Perl regular +expressions: `m' allows regexps to match more than one line, while `s' +(which implies `m') means that `.' matches newlines. The ability to +span newlines allows writing of much more powerful regular expressions +and rapid prototyping for tagging new languages. + +**** Regular expressions can use char escape sequences as in GCC. + +The escaped character sequence \a, \b, \d, \e, \f, \n, \r, \t, \v, +respectively, stand for the ASCII characters BEL, BS, DEL, ESC, FF, NL, +CR, TAB, VT. + +**** Regular expressions can be bound to a given language. + +The syntax --regex={LANGUAGE}REGEX means that REGEX is used to make tags +only for files of language LANGUAGE, and ignored otherwise. This is +particularly useful when storing regexps in a file. + +**** Regular expressions can be read from a file. + +The --regex=@regexfile option means read the regexps from a file, one +per line. Lines beginning with space or tab are ignored. + +*** New language parsing features + +**** New language HTML. + +Tags are generated for `title' as well as `h1', `h2', and `h3'. Also, +when `name=' is used inside an anchor and whenever `id=' is used. + +**** New language PHP. + +Functions, classes and defines are tags. If the --members option is +specified to etags, variables are tags also. + +**** New language Lua. + +All functions are tagged. + +**** The `::' qualifier triggers C++ parsing in C file. + +Previously, only the `template' and `class' keywords had this effect. + +**** The GCC __attribute__ keyword is now recognized and ignored. + +**** In C and derived languages, etags creates tags for #undef + +**** In Makefiles, constants are tagged. + +If you want the old behavior instead, thus avoiding to increase the +size of the tags file, use the --no-globals option. + +**** In Perl, packages are tags. + +Subroutine tags are named from their package. You can jump to sub tags +as you did before, by the sub name, or additionally by looking for +package::sub. + +**** In Prolog, etags creates tags for rules in addition to predicates. + +**** New default keywords for TeX. + +The new keywords are def, newcommand, renewcommand, newenvironment and +renewenvironment. + +*** Honor #line directives. + +When Etags parses an input file that contains C preprocessor's #line +directives, it creates tags using the file name and line number +specified in those directives. This is useful when dealing with code +created from Cweb source files. When Etags tags the generated file, it +writes tags pointing to the source file. + +*** New option --parse-stdin=FILE. + +This option is mostly useful when calling etags from programs. It can +be used (only once) in place of a file name on the command line. Etags +reads from standard input and marks the produced tags as belonging to +the file FILE. + +*** The --members option is now the default. + +Use --no-members if you want the old default behaviour of not tagging +struct members in C, members variables in C++ and variables in PHP. + +** Ctags changes. + +*** Ctags now allows duplicate tags + +** Rmail changes + +*** Support for `movemail' from GNU mailutils was added to Rmail. + +This version of `movemail' allows you to read mail from a wide range of +mailbox formats, including remote POP3 and IMAP4 mailboxes with or +without TLS encryption. If GNU mailutils is installed on the system +and its version of `movemail' can be found in exec-path, it will be +used instead of the native one. + +*** The new commands rmail-end-of-message and rmail-summary end-of-message, +by default bound to `/', go to the end of the current mail message in +Rmail and Rmail summary buffers. + +*** Rmail now displays 5-digit message ids in its summary buffer. + +** Gnus package + +*** Gnus now includes Sieve and PGG + +Sieve is a library for managing Sieve scripts. PGG is a library to handle +PGP/MIME. + +*** There are many news features, bug fixes and improvements. + +See the file GNUS-NEWS or the node "Oort Gnus" in the Gnus manual for details. + +** MH-E changes. + +Upgraded to MH-E version 8.0.3. There have been major changes since +version 5.0.2; see MH-E-NEWS for details. + +** Miscellaneous mail changes + +*** The new variable `mail-default-directory' specifies +`default-directory' for mail buffers. This directory is used for +auto-save files of mail buffers. It defaults to "~/". + +*** The mode line can indicate new mail in a directory or file. + +See the documentation of the user option `display-time-mail-directory'. + +** Calendar changes + +*** There is a new calendar package, icalendar.el, that can be used to +convert Emacs diary entries to/from the iCalendar format. + +*** The new package cal-html.el writes HTML files with calendar and +diary entries. + +*** The new functions `diary-from-outlook', `diary-from-outlook-gnus', +and `diary-from-outlook-rmail' can be used to import diary entries +from Outlook-format appointments in mail messages. The variable +`diary-outlook-formats' can be customized to recognize additional +formats. + +*** The procedure for activating appointment reminders has changed: +use the new function `appt-activate'. The new variable +`appt-display-format' controls how reminders are displayed, replacing +`appt-issue-message', `appt-visible', and `appt-msg-window'. + +*** The function `simple-diary-display' now by default sets a header line. +This can be controlled through the variables `diary-header-line-flag' +and `diary-header-line-format'. + +*** Diary sexp entries can have custom marking in the calendar. +Diary sexp functions which only apply to certain days (such as +`diary-block' or `diary-cyclic') now take an optional parameter MARK, +which is the name of a face or a single-character string indicating +how to highlight the day in the calendar display. Specifying a +single-character string as @var{mark} places the character next to the +day in the calendar. Specifying a face highlights the day with that +face. This lets you have different colors or markings for vacations, +appointments, paydays or anything else using a sexp. + +*** The meanings of C-x < and C-x > have been interchanged. +< means to scroll backward in time, and > means to scroll forward. + +*** You can now use < and >, instead of C-x < and C-x >, to scroll +the calendar left or right. + +*** The new function `calendar-goto-day-of-year' (g D) prompts for a +year and day number, and moves to that date. Negative day numbers +count backward from the end of the year. + +*** The new Calendar function `calendar-goto-iso-week' (g w) +prompts for a year and a week number, and moves to the first +day of that ISO week. + +*** The functions `holiday-easter-etc' and `holiday-advent' now take +optional arguments, in order to only report on the specified holiday +rather than all. This makes customization of variables such as +`christian-holidays' simpler. + +*** The new variable `calendar-minimum-window-height' affects the +window generated by the function `generate-calendar-window'. + +** Speedbar changes + +*** Speedbar items can now be selected by clicking mouse-1, based on +the `mouse-1-click-follows-link' mechanism. + +*** The new command `speedbar-toggle-line-expansion', bound to SPC, +contracts or expands the line under the cursor. + +*** New command `speedbar-create-directory', bound to `M'. + +*** The new commands `speedbar-expand-line-descendants' and +`speedbar-contract-line-descendants', bound to `[' and `]' +respectively, expand and contract the line under cursor with all of +its descendents. + +*** The new user option `speedbar-use-tool-tips-flag', if non-nil, +means to display tool-tips for speedbar items. + +*** The new user option `speedbar-query-confirmation-method' controls +how querying is performed for file operations. A value of 'always +means to always query before file operations; 'none-but-delete means +to not query before any file operations, except before a file +deletion. + +*** The new user option `speedbar-select-frame-method' specifies how +to select a frame for displaying a file opened with the speedbar. A +value of 'attached means to use the attached frame (the frame that +speedbar was started from.) A number such as 1 or -1 means to pass +that number to `other-frame'. + +*** SPC and DEL are no longer bound to scroll up/down in the speedbar +keymap. + +*** The frame management code in speedbar.el has been split into a new +`dframe' library. Emacs Lisp code that makes use of the speedbar +should use `dframe-attached-frame' instead of +`speedbar-attached-frame', `dframe-timer' instead of `speedbar-timer', +`dframe-close-frame' instead of `speedbar-close-frame', and +`dframe-activity-change-focus-flag' instead of +`speedbar-activity-change-focus-flag'. The variables +`speedbar-update-speed' and `speedbar-navigating-speed' are also +obsolete; use `dframe-update-speed' instead. + +** battery.el changes + +*** display-battery-mode replaces display-battery. + +*** battery.el now works on recent versions of OS X. + +** Games + +*** The game `mpuz' is enhanced. + +`mpuz' now allows the 2nd factor not to have two identical digits. By +default, all trivial operations involving whole lines are performed +automatically. The game uses faces for better visual feedback. + +** Obsolete and deleted packages + +*** fast-lock.el and lazy-lock.el are obsolete. Use jit-lock.el instead. + +*** iso-acc.el is now obsolete. Use one of the latin input methods instead. + +*** zone-mode.el is now obsolete. Use dns-mode.el instead. + +*** cplus-md.el has been deleted. + +** Miscellaneous + +*** The variable `woman-topic-at-point' is renamed +to `woman-use-topic-at-point' and behaves differently: if this +variable is non-nil, the `woman' command uses the word at point +automatically, without asking for a confirmation. Otherwise, the word +at point is suggested as default, but not inserted at the prompt. + +*** You can now customize `fill-nobreak-predicate' to control where +filling can break lines. The value is now normally a list of +functions, but it can also be a single function, for compatibility. + +Emacs provide two predicates, `fill-single-word-nobreak-p' and +`fill-french-nobreak-p', for use as the value of +`fill-nobreak-predicate'. + +*** M-x view-file and commands that use it now avoid interfering +with special modes such as Tar mode. + +*** `global-whitespace-mode' is a new alias for `whitespace-global-mode'. + +*** The saveplace.el package now filters out unreadable files. + +When you exit Emacs, the saved positions in visited files no longer +include files that aren't readable, e.g. files that don't exist. +Customize the new option `save-place-forget-unreadable-files' to nil +to get the old behavior. The new options `save-place-save-skipped' +and `save-place-skip-check-regexp' allow further fine-tuning of this +feature. + +*** Commands `winner-redo' and `winner-undo', from winner.el, are now +bound to C-c and C-c , respectively. This is an +incompatible change. + +*** The type-break package now allows `type-break-file-name' to be nil +and if so, doesn't store any data across sessions. This is handy if +you don't want the `.type-break' file in your home directory or are +annoyed by the need for interaction when you kill Emacs. + +*** `ps-print' can now print characters from the mule-unicode charsets. + +Printing text with characters from the mule-unicode-* sets works with +`ps-print', provided that you have installed the appropriate BDF +fonts. See the file INSTALL for URLs where you can find these fonts. + +*** New command `strokes-global-set-stroke-string'. +This is like `strokes-global-set-stroke', but it allows you to bind +the stroke directly to a string to insert. This is convenient for +using strokes as an input method. + +*** In Outline mode, `hide-body' no longer hides lines at the top +of the file that precede the first header line. + +*** `hide-ifdef-mode' now uses overlays rather than selective-display +to hide its text. This should be mostly transparent but slightly +changes the behavior of motion commands like C-e and C-p. + +*** In Artist mode the variable `artist-text-renderer' has been +renamed to `artist-text-renderer-function'. The old name is still +available as alias. + +*** In Enriched mode, `set-left-margin' and `set-right-margin' are now +by default bound to `C-c [' and `C-c ]' instead of the former `C-c C-l' +and `C-c C-r'. + +*** `partial-completion-mode' now handles partial completion on directory names. + +*** You can now disable pc-selection-mode after enabling it. + +M-x pc-selection-mode behaves like a proper minor mode, and with no +argument it toggles the mode. Turning off PC-Selection mode restores +the global key bindings that were replaced by turning on the mode. + +*** `uniquify-strip-common-suffix' tells uniquify to prefer +`file|dir1' and `file|dir2' to `file|dir1/subdir' and `file|dir2/subdir'. + +*** New user option `add-log-always-start-new-record'. + +When this option is enabled, M-x add-change-log-entry always +starts a new record regardless of when the last record is. + +*** M-x compare-windows now can automatically skip non-matching text to +resync points in both windows. + +*** PO translation files are decoded according to their MIME headers +when Emacs visits them. + +*** Telnet now prompts you for a port number with C-u M-x telnet. + +*** calculator.el now has radix grouping mode. + +To enable this, set `calculator-output-radix' non-nil. In this mode a +separator character is used every few digits, making it easier to see +byte boundaries etc. For more info, see the documentation of the +variable `calculator-radix-grouping-mode'. + +*** LDAP support now defaults to ldapsearch from OpenLDAP version 2. + +*** The terminal emulation code in term.el has been improved; it can +run most curses applications now. + +*** Support for `magic cookie' standout modes has been removed. + +Emacs still works on terminals that require magic cookies in order to +use standout mode, but they can no longer display mode-lines in +inverse-video. + + +* Changes in Emacs 22.1 on non-free operating systems + +** The HOME directory defaults to Application Data under the user profile. + +If you used a previous version of Emacs without setting the HOME +environment variable and a `.emacs' was saved, then Emacs will continue +using C:/ as the default HOME. But if you are installing Emacs afresh, +the default location will be the "Application Data" (or similar +localized name) subdirectory of your user profile. A typical location +of this directory is "C:\Documents and Settings\USERNAME\Application Data", +where USERNAME is your user name. + +This change means that users can now have their own `.emacs' files on +shared computers, and the default HOME directory is less likely to be +read-only on computers that are administered by someone else. + +** Images are now supported on MS Windows. + +PBM and XBM images are supported out of the box. Other image formats +depend on external libraries. All of these libraries have been ported +to Windows, and can be found in both source and binary form at +http://gnuwin32.sourceforge.net/. Note that libpng also depends on +zlib, and tiff depends on the version of jpeg that it was compiled +against. For additional information, see nt/INSTALL. + +** Sound is now supported on MS Windows. + +WAV format is supported on all versions of Windows, other formats such +as AU, AIFF and MP3 may be supported in the more recent versions of +Windows, or when other software provides hooks into the system level +sound support for those formats. + +** Tooltips now work on MS Windows. + +See the Emacs 21.1 NEWS entry for tooltips for details. + +** Pointing devices with more than 3 buttons are now supported on MS Windows. + +The new variable `w32-pass-extra-mouse-buttons-to-system' controls +whether Emacs should handle the extra buttons itself (the default), or +pass them to Windows to be handled with system-wide functions. + +** Passing resources on the command line now works on MS Windows. + +You can use --xrm to pass resource settings to Emacs, overriding any +existing values. For example: + + emacs --xrm "Emacs.Background:red" --xrm "Emacs.Geometry:100x20" + +will start up Emacs on an initial frame of 100x20 with red background, +irrespective of geometry or background setting on the Windows registry. + +** Emacs takes note of colors defined in Control Panel on MS-Windows. + +The Control Panel defines some default colors for applications in much +the same way as wildcard X Resources do on X. Emacs now adds these +colors to the colormap prefixed by System (eg SystemMenu for the +default Menu background, SystemMenuText for the foreground), and uses +some of them to initialize some of the default faces. +`list-colors-display' shows the list of System color names, in case +you wish to use them in other faces. + +** Running in a console window in Windows now uses the console size. + +Previous versions of Emacs erred on the side of having a usable Emacs +through telnet, even though that was inconvenient if you use Emacs in +a local console window with a scrollback buffer. The default value of +w32-use-full-screen-buffer is now nil, which favors local console +windows. Recent versions of Windows telnet also work well with this +setting. If you are using an older telnet server then Emacs detects +that the console window dimensions that are reported are not sane, and +defaults to 80x25. If you use such a telnet server regularly at a size +other than 80x25, you can still manually set +w32-use-full-screen-buffer to t. + +** Different shaped mouse pointers are supported on MS Windows. + +The mouse pointer changes shape depending on what is under the pointer. + +** On MS Windows, the "system caret" now follows the cursor. + +This enables Emacs to work better with programs that need to track the +cursor, for example screen magnifiers and text to speech programs. +When such a program is in use, the system caret is made visible +instead of Emacs drawing its own cursor. This seems to be required by +some programs. The new variable w32-use-visible-system-caret allows +the caret visibility to be manually toggled. + +** On MS Windows NT/W2K/XP, Emacs uses Unicode for clipboard operations. + +Those systems use Unicode internally, so this allows Emacs to share +multilingual text with other applications. On other versions of +MS Windows, Emacs now uses the appropriate locale coding-system, so +the clipboard should work correctly for your local language without +any customizations. + +** On Mac OS, `keyboard-coding-system' changes based on the keyboard script. + +** The variable `mac-keyboard-text-encoding' and the constants +`kTextEncodingMacRoman', `kTextEncodingISOLatin1', and +`kTextEncodingISOLatin2' are obsolete. + +** The variable `mac-command-key-is-meta' is obsolete. Use +`mac-command-modifier' and `mac-option-modifier' instead. + +* Incompatible Lisp Changes in Emacs 22.1 + +** Mode line display ignores text properties as well as the +:propertize and :eval forms in the value of a variable whose +`risky-local-variable' property is nil. + +The function `comint-send-input' now accepts 3 optional arguments: + + (comint-send-input &optional no-newline artificial) + +Callers sending input not from the user should use bind the 3rd +argument `artificial' to a non-nil value, to prevent Emacs from +deleting the part of subprocess output that matches the input. + +** The `read-file-name' function now returns a null string if the +user just types RET. + +** The variables post-command-idle-hook and post-command-idle-delay have +been removed. Use run-with-idle-timer instead. + +** A hex or octal escape in a string constant forces the string to +be multibyte or unibyte, respectively. + +** The explicit method of creating a display table element by +combining a face number and a character code into a numeric +glyph code is deprecated. + +Instead, the new functions `make-glyph-code', `glyph-char', and +`glyph-face' must be used to create and decode glyph codes in +display tables. + +** `suppress-keymap' now works by remapping `self-insert-command' to +the command `undefined'. (In earlier Emacs versions, it used +`substitute-key-definition' to rebind self inserting characters to +`undefined'.) + +** The third argument of `accept-process-output' is now milliseconds. +It used to be microseconds. + +** The function find-operation-coding-system may be called with a cons +(FILENAME . BUFFER) in the second argument if the first argument +OPERATION is `insert-file-contents', and thus a function registered in +`file-coding-system-alist' is also called with such an argument. + +** When Emacs receives a USR1 or USR2 signal, this generates +input events: sigusr1 or sigusr2. Use special-event-map to +handle these events. + +** The variable `memory-full' now remains t until +there is no longer a shortage of memory. + +** Support for Mocklisp has been removed. + + +* Lisp Changes in Emacs 22.1 + +** General Lisp changes: + +*** New syntax: \s now stands for the SPACE character. + +`?\s' is a new way to write the space character. You must make sure +it is not followed by a dash, since `?\s-...' indicates the "super" +modifier. However, it would be strange to write a character constant +and a following symbol (beginning with `-') with no space between +them. + +`\s' stands for space in strings, too, but it is not really meant for +strings; it is easier and nicer just to write a space. + +*** New syntax: \uXXXX and \UXXXXXXXX specify Unicode code points in hex. + +For instance, you can use "\u0428" to specify a string consisting of +CYRILLIC CAPITAL LETTER SHA, or `"U0001D6E2" to specify one consisting +of MATHEMATICAL ITALIC CAPITAL ALPHA (the latter is greater than +#xFFFF and thus needs the longer syntax). + +This syntax works for both character constants and strings. + +*** New function `unsafep' determines whether a Lisp form is safe. + +It returns nil if the given Lisp form can't possibly do anything +dangerous; otherwise it returns a reason why the form might be unsafe +(calls unknown function, alters global variable, etc.). + +*** The function `eql' is now available without requiring the CL package. + +*** The new function `memql' is like `memq', but uses `eql' for comparison, +that is, floats are compared by value and other elements with `eq'. + +*** New functions `string-or-null-p' and `booleanp'. + - `string-or-null-p' returns non-nil iff OBJECT is a string or nil. - `booleanp' returns non-nil iff OBJECT is t or nil. ++`string-or-null-p' returns non-nil if OBJECT is a string or nil. ++`booleanp' returns non-nil if OBJECT is t or nil. + +*** `makehash' is now obsolete. Use `make-hash-table' instead. + +*** Minor change in the function `format'. + +Some flags that were accepted but not implemented (such as "*") are no +longer accepted. + +*** `add-to-list' takes an optional third argument, APPEND. + +If APPEND is non-nil, the new element gets added at the end of the +list instead of at the beginning. This change actually occurred in +Emacs 21.1, but was not documented then. + +*** New function `add-to-ordered-list' is like `add-to-list' but +associates a numeric ordering of each element added to the list. + +*** New function `add-to-history' adds an element to a history list. + +Lisp packages should use this function to add elements to their +history lists. + +If `history-delete-duplicates' is non-nil, it removes duplicates of +the new element from the history list it updates. + +*** New function `copy-tree' makes a copy of a tree. + +It recursively copies through both CARs and CDRs. + +*** New function `delete-dups' deletes `equal' duplicate elements from a list. + +It modifies the list destructively, like `delete'. Of several `equal' +occurrences of an element in the list, the one that's kept is the +first one. + +*** New function `rassq-delete-all'. + +(rassq-delete-all VALUE ALIST) deletes, from ALIST, each element whose +CDR is `eq' to the specified value. + +*** Functions `get' and `plist-get' no longer give errors for bad plists. + +They return nil for a malformed property list or if the list is +cyclic. + +*** New functions `lax-plist-get' and `lax-plist-put'. + +They are like `plist-get' and `plist-put', except that they compare +the property name using `equal' rather than `eq'. + +*** The function `number-sequence' makes a list of equally-separated numbers. + +For instance, (number-sequence 4 9) returns (4 5 6 7 8 9). By +default, the separation is 1, but you can specify a different +separation as the third argument. (number-sequence 1.5 6 2) returns +(1.5 3.5 5.5). + +*** New variables `most-positive-fixnum' and `most-negative-fixnum'. + +They hold the largest and smallest possible integer values. + +*** The function `expt' handles negative exponents differently. +The value for `(expt A B)', if both A and B are integers and B is +negative, is now a float. For example: (expt 2 -2) => 0.25. + +*** The function `atan' now accepts an optional second argument. + +When called with 2 arguments, as in `(atan Y X)', `atan' returns the +angle in radians between the vector [X, Y] and the X axis. (This is +equivalent to the standard C library function `atan2'.) + +*** New macro `with-case-table' + +This executes the body with the case table temporarily set to a given +case table. + +*** New macro `with-local-quit' temporarily allows quitting. + +A quit inside the body of `with-local-quit' is caught by the +`with-local-quit' form itself, but another quit will happen later once +the code that has inhibited quitting exits. + +This is for use around potentially blocking or long-running code +inside timer functions and `post-command-hook' functions. + +*** New macro `define-obsolete-function-alias'. + +This combines `defalias' and `make-obsolete'. + +*** New macro `eval-at-startup' specifies expressions to +evaluate when Emacs starts up. If this is done after startup, +it evaluates those expressions immediately. + +This is useful in packages that can be preloaded. + +*** New function `macroexpand-all' expands all macros in a form. + +It is similar to the Common-Lisp function of the same name. +One difference is that it guarantees to return the original argument +if no expansion is done, which can be tested using `eq'. + +*** A function or macro's doc string can now specify the calling pattern. + +You put this info in the doc string's last line. It should be +formatted so as to match the regexp "\n\n(fn .*)\\'". If you don't +specify this explicitly, Emacs determines it from the actual argument +names. Usually that default is right, but not always. + +*** New variable `print-continuous-numbering'. + +When this is non-nil, successive calls to print functions use a single +numbering scheme for circular structure references. This is only +relevant when `print-circle' is non-nil. + +When you bind `print-continuous-numbering' to t, you should +also bind `print-number-table' to nil. + +*** `list-faces-display' takes an optional argument, REGEXP. + +If it is non-nil, the function lists only faces matching this regexp. + +*** New hook `command-error-function'. + +By setting this variable to a function, you can control +how the editor command loop shows the user an error message. + +*** `debug-on-entry' accepts primitive functions that are not special forms. + +** Lisp code indentation features: + +*** The `defmacro' form can contain indentation and edebug declarations. + +These declarations specify how to indent the macro calls in Lisp mode +and how to debug them with Edebug. You write them like this: + + (defmacro NAME LAMBDA-LIST [DOC-STRING] [DECLARATION ...] ...) + +DECLARATION is a list `(declare DECLARATION-SPECIFIER ...)'. The +possible declaration specifiers are: + +(indent INDENT) + Set NAME's `lisp-indent-function' property to INDENT. + +(edebug DEBUG) + Set NAME's `edebug-form-spec' property to DEBUG. (This is + equivalent to writing a `def-edebug-spec' for the macro, + but this is cleaner.) + +*** cl-indent now allows customization of Indentation of backquoted forms. + +See the new user option `lisp-backquote-indentation'. + +*** cl-indent now handles indentation of simple and extended `loop' forms. + +The new user options `lisp-loop-keyword-indentation', +`lisp-loop-forms-indentation', and `lisp-simple-loop-indentation' can +be used to customize the indentation of keywords and forms in loop +forms. + +** Variable aliases: + +*** New function: defvaralias ALIAS-VAR BASE-VAR [DOCSTRING] + +This function defines the symbol ALIAS-VAR as a variable alias for +symbol BASE-VAR. This means that retrieving the value of ALIAS-VAR +returns the value of BASE-VAR, and changing the value of ALIAS-VAR +changes the value of BASE-VAR. + +DOCSTRING, if present, is the documentation for ALIAS-VAR; else it has +the same documentation as BASE-VAR. + +*** The macro `define-obsolete-variable-alias' combines `defvaralias' and +`make-obsolete-variable'. + +*** New function: indirect-variable VARIABLE + +This function returns the variable at the end of the chain of aliases +of VARIABLE. If VARIABLE is not a symbol, or if VARIABLE is not +defined as an alias, the function returns VARIABLE. + +It might be noteworthy that variables aliases work for all kinds of +variables, including buffer-local and frame-local variables. + +** defcustom changes: + +*** The package-version keyword has been added to provide +`customize-changed-options' functionality to packages in the future. +Developers who make use of this keyword must also update the new +variable `customize-package-emacs-version-alist'. + +*** The new customization type `float' requires a floating point number. + +** String changes: + +*** A hex escape in a string constant forces the string to be multibyte. + +*** An octal escape in a string constant forces the string to be unibyte. + +*** New function `string-to-multibyte' converts a unibyte string to a +multibyte string with the same individual character codes. + +*** `split-string' now includes null substrings in the returned list if +the optional argument SEPARATORS is non-nil and there are matches for +SEPARATORS at the beginning or end of the string. If SEPARATORS is +nil, or if the new optional third argument OMIT-NULLS is non-nil, all +empty matches are omitted from the returned list. + +*** The new function `assoc-string' replaces `assoc-ignore-case' and +`assoc-ignore-representation', which are still available, but have +been declared obsolete. + +*** New function `substring-no-properties' returns a substring without +text properties. + +** Displaying warnings to the user. + +See the functions `warn' and `display-warning', or the Lisp Manual. +If you want to be sure the warning will not be overlooked, this +facility is much better than using `message', since it displays +warnings in a separate window. + +** Progress reporters. + +These provide a simple and uniform way for commands to present +progress messages for the user. + +See the new functions `make-progress-reporter', +`progress-reporter-update', `progress-reporter-force-update', +`progress-reporter-done', and `dotimes-with-progress-reporter'. + +** Buffer positions: + +*** Function `compute-motion' now calculates the usable window +width if the WIDTH argument is nil. If the TOPOS argument is nil, +the usable window height and width is used. + +*** The `line-move', `scroll-up', and `scroll-down' functions will now +modify the window vscroll to scroll through display rows that are +taller that the height of the window, for example in the presence of +large images. To disable this feature, bind the new variable +`auto-window-vscroll' to nil. + +*** The argument to `forward-word', `backward-word' is optional. + +It defaults to 1. + +*** Argument to `forward-to-indentation' and `backward-to-indentation' is optional. + +It defaults to 1. + +*** `field-beginning' and `field-end' take new optional argument, LIMIT. + +This argument tells them not to search beyond LIMIT. Instead they +give up and return LIMIT. + +*** New function `window-line-height' is an efficient way to get +information about a specific text line in a window provided that the +window's display is up-to-date. + +*** New function `line-number-at-pos' returns the line number of a position. + +It an optional buffer position argument that defaults to point. + +*** Function `pos-visible-in-window-p' now returns the pixel coordinates +and partial visibility state of the corresponding row, if the PARTIALLY +arg is non-nil. + +*** New functions `posn-at-point' and `posn-at-x-y' return +click-event-style position information for a given visible buffer +position or for a given window pixel coordinate. + +*** New function `mouse-on-link-p' tests if a position is in a clickable link. + +This is the function used by the new `mouse-1-click-follows-link' +functionality. + +** Text modification: + +*** The new function `buffer-chars-modified-tick' returns a buffer's +tick counter for changes to characters. Each time text in that buffer +is inserted or deleted, the character-change counter is updated to the +tick counter (`buffer-modified-tick'). Text property changes leave it +unchanged. + +*** The new function `insert-for-yank' normally works like `insert', but +removes the text properties in the `yank-excluded-properties' list +and handles the `yank-handler' text property. + +*** The new function `insert-buffer-substring-as-yank' is like +`insert-for-yank' except that it gets the text from another buffer as +in `insert-buffer-substring'. + +*** The new function `insert-buffer-substring-no-properties' is like +`insert-buffer-substring', but removes all text properties from the +inserted substring. + +*** The new function `filter-buffer-substring' extracts a buffer +substring, passes it through a set of filter functions, and returns +the filtered substring. Use it instead of `buffer-substring' or +`delete-and-extract-region' when copying text into a user-accessible +data structure, such as the kill-ring, X clipboard, or a register. + +The list of filter function is specified by the new variable +`buffer-substring-filters'. For example, Longlines mode adds to +`buffer-substring-filters' to remove soft newlines from the copied +text. + +*** Function `translate-region' accepts also a char-table as TABLE +argument. + +*** The new translation table `translation-table-for-input' +is used for customizing self-insertion. The character to +be inserted is translated through it. + +*** Text clones. + +The new function `text-clone-create'. Text clones are chunks of text +that are kept identical by transparently propagating changes from one +clone to the other. + +*** The function `insert-string' is now obsolete. + +** Filling changes. + +*** In determining an adaptive fill prefix, Emacs now tries the function in +`adaptive-fill-function' _before_ matching the buffer line against +`adaptive-fill-regexp' rather than _after_ it. + +** Atomic change groups. + +To perform some changes in the current buffer "atomically" so that +they either all succeed or are all undone, use `atomic-change-group' +around the code that makes changes. For instance: + + (atomic-change-group + (insert foo) + (delete-region x y)) + +If an error (or other nonlocal exit) occurs inside the body of +`atomic-change-group', it unmakes all the changes in that buffer that +were during the execution of the body. The change group has no effect +on any other buffers--any such changes remain. + +If you need something more sophisticated, you can directly call the +lower-level functions that `atomic-change-group' uses. Here is how. + +To set up a change group for one buffer, call `prepare-change-group'. +Specify the buffer as argument; it defaults to the current buffer. +This function returns a "handle" for the change group. You must save +the handle to activate the change group and then finish it. + +Before you change the buffer again, you must activate the change +group. Pass the handle to `activate-change-group' afterward to +do this. + +After you make the changes, you must finish the change group. You can +either accept the changes or cancel them all. Call +`accept-change-group' to accept the changes in the group as final; +call `cancel-change-group' to undo them all. + +You should use `unwind-protect' to make sure the group is always +finished. The call to `activate-change-group' should be inside the +`unwind-protect', in case the user types C-g just after it runs. +(This is one reason why `prepare-change-group' and +`activate-change-group' are separate functions.) Once you finish the +group, don't use the handle again--don't try to finish the same group +twice. + +To make a multibuffer change group, call `prepare-change-group' once +for each buffer you want to cover, then use `nconc' to combine the +returned values, like this: + + (nconc (prepare-change-group buffer-1) + (prepare-change-group buffer-2)) + +You can then activate the multibuffer change group with a single call +to `activate-change-group', and finish it with a single call to +`accept-change-group' or `cancel-change-group'. + +Nested use of several change groups for the same buffer works as you +would expect. Non-nested use of change groups for the same buffer +will lead to undesirable results, so don't let it happen; the first +change group you start for any given buffer should be the last one +finished. + +** Buffer-related changes: + +*** The new function `buffer-local-value' returns the buffer-local +binding of VARIABLE (a symbol) in buffer BUFFER. If VARIABLE does not +have a buffer-local binding in buffer BUFFER, it returns the default +value of VARIABLE instead. + +*** `list-buffers-noselect' now takes an additional argument, BUFFER-LIST. + +If it is non-nil, it specifies which buffers to list. + +*** `kill-buffer-hook' is now a permanent local. + +*** The function `frame-or-buffer-changed-p' now lets you maintain +various status records in parallel. + +It takes a variable (a symbol) as argument. If the variable is non-nil, +then its value should be a vector installed previously by +`frame-or-buffer-changed-p'. If the frame names, buffer names, buffer +order, or their read-only or modified flags have changed, since the +time the vector's contents were recorded by a previous call to +`frame-or-buffer-changed-p', then the function returns t. Otherwise +it returns nil. + +On the first call to `frame-or-buffer-changed-p', the variable's +value should be nil. `frame-or-buffer-changed-p' stores a suitable +vector into the variable and returns t. + +If the variable is itself nil, then `frame-or-buffer-changed-p' uses, +for compatibility, an internal variable which exists only for this +purpose. + +*** The function `read-buffer' follows the convention for reading from +the minibuffer with a default value: if DEF is non-nil, the minibuffer +prompt provided in PROMPT is edited to show the default value provided +in DEF before the terminal colon and space. + +** Searching and matching changes: + +*** New function `looking-back' checks whether a regular expression matches +the text before point. Specifying the LIMIT argument bounds how far +back the match can start; this is a way to keep it from taking too long. + +*** The new variable `search-spaces-regexp' controls how to search +for spaces in a regular expression. If it is non-nil, it should be a +regular expression, and any series of spaces stands for that regular +expression. If it is nil, spaces stand for themselves. + +Spaces inside of constructs such as `[..]' and inside loops such as +`*', `+', and `?' are never replaced with `search-spaces-regexp'. + +*** New regular expression operators, `\_<' and `\_>'. + +These match the beginning and end of a symbol. A symbol is a +non-empty sequence of either word or symbol constituent characters, as +specified by the syntax table. + +*** `skip-chars-forward' and `skip-chars-backward' now handle +character classes such as `[:alpha:]', along with individual +characters and ranges. + +*** In `replace-match', the replacement text no longer inherits +properties from surrounding text. + +*** The list returned by `(match-data t)' now has the buffer as a final +element, if the last match was on a buffer. `set-match-data' +accepts such a list for restoring the match state. + +*** Functions `match-data' and `set-match-data' now have an optional +argument `reseat'. When non-nil, all markers in the match data list +passed to these functions will be reseated to point to nowhere. + +*** rx.el has new corresponding `symbol-start' and `symbol-end' elements. + +*** The default value of `sentence-end' is now defined using the new +variable `sentence-end-without-space', which contains such characters +that end a sentence without following spaces. + +The function `sentence-end' should be used to obtain the value of the +variable `sentence-end'. If the variable `sentence-end' is nil, then +this function returns the regexp constructed from the variables +`sentence-end-without-period', `sentence-end-double-space' and +`sentence-end-without-space'. + +** Undo changes: + +*** `buffer-undo-list' allows programmable elements. + +These elements have the form (apply FUNNAME . ARGS), where FUNNAME is +a symbol other than t or nil. That stands for a high-level change +that should be undone by evaluating (apply FUNNAME ARGS). + +These entries can also have the form (apply DELTA BEG END FUNNAME . ARGS) +which indicates that the change which took place was limited to the +range BEG...END and increased the buffer size by DELTA. + +*** If the buffer's undo list for the current command gets longer than +`undo-outer-limit', garbage collection empties it. This is to prevent +it from using up the available memory and choking Emacs. + +** Killing and yanking changes: + +*** New `yank-handler' text property can be used to control how +previously killed text on the kill ring is reinserted. + +The value of the `yank-handler' property must be a list with one to four +elements with the following format: + (FUNCTION PARAM NOEXCLUDE UNDO). + +The `insert-for-yank' function looks for a yank-handler property on +the first character on its string argument (typically the first +element on the kill-ring). If a `yank-handler' property is found, +the normal behavior of `insert-for-yank' is modified in various ways: + + When FUNCTION is present and non-nil, it is called instead of `insert' +to insert the string. FUNCTION takes one argument--the object to insert. + If PARAM is present and non-nil, it replaces STRING as the object +passed to FUNCTION (or `insert'); for example, if FUNCTION is +`yank-rectangle', PARAM should be a list of strings to insert as a +rectangle. + If NOEXCLUDE is present and non-nil, the normal removal of the +`yank-excluded-properties' is not performed; instead FUNCTION is +responsible for removing those properties. This may be necessary +if FUNCTION adjusts point before or after inserting the object. + If UNDO is present and non-nil, it is a function that will be called +by `yank-pop' to undo the insertion of the current object. It is +called with two arguments, the start and end of the current region. +FUNCTION can set `yank-undo-function' to override the UNDO value. + +*** The functions `kill-new', `kill-append', and `kill-region' now have an +optional argument to specify the `yank-handler' text property to put on +the killed text. + +*** The function `yank-pop' will now use a non-nil value of the variable +`yank-undo-function' (instead of `delete-region') to undo the previous +`yank' or `yank-pop' command (or a call to `insert-for-yank'). The function +`insert-for-yank' automatically sets that variable according to the UNDO +element of the string argument's `yank-handler' text property if present. + +*** The function `insert-for-yank' now supports strings where the +`yank-handler' property does not span the first character of the +string. The old behavior is available if you call +`insert-for-yank-1' instead. + +** Syntax table changes: + +*** The new function `syntax-ppss' provides an efficient way to find the +current syntactic context at point. + +*** The new function `syntax-after' returns the syntax code +of the character after a specified buffer position, taking account +of text properties as well as the character code. + +*** `syntax-class' extracts the class of a syntax code (as returned +by `syntax-after'). + +*** The macro `with-syntax-table' no longer copies the syntax table. + +** File operation changes: + +*** New vars `exec-suffixes' and `load-suffixes' used when +searching for an executable or an Emacs Lisp file. + +*** New function `locate-file' searches for a file in a list of directories. +`locate-file' accepts a name of a file to search (a string), and two +lists: a list of directories to search in and a list of suffixes to +try; typical usage might use `exec-path' and `load-path' for the list +of directories, and `exec-suffixes' and `load-suffixes' for the list +of suffixes. The function also accepts a predicate argument to +further filter candidate files. + +One advantage of using this function is that the list of suffixes in +`exec-suffixes' is OS-dependant, so this function will find +executables without polluting Lisp code with OS dependencies. + +*** The new function `file-remote-p' tests a file name and returns +non-nil if it specifies a remote file (one that Emacs accesses using +its own special methods and not directly through the file system). +The value in that case is an identifier for the remote file system. + +*** The new hook `before-save-hook' is invoked by `basic-save-buffer' +before saving buffers. This allows packages to perform various final +tasks. For example, it can be used by the copyright package to make +sure saved files have the current year in any copyright headers. + +*** `file-chase-links' now takes an optional second argument LIMIT which +specifies the maximum number of links to chase through. If after that +many iterations the file name obtained is still a symbolic link, +`file-chase-links' returns it anyway. + +*** Functions `file-name-sans-extension' and `file-name-extension' now +ignore the leading dots in file names, so that file names such as +`.emacs' are treated as extensionless. + +*** If `buffer-save-without-query' is non-nil in some buffer, +`save-some-buffers' will always save that buffer without asking (if +it's modified). + +*** `buffer-auto-save-file-format' is the new name for what was +formerly called `auto-save-file-format'. It is now a permanent local. + +*** `visited-file-modtime' and `calendar-time-from-absolute' now return +a list of two integers, instead of a cons. + +*** The precedence of file name handlers has been changed. + +Instead of choosing the first handler that matches, +`find-file-name-handler' now gives precedence to a file name handler +that matches nearest the end of the file name. More precisely, the +handler whose (match-beginning 0) is the largest is chosen. In case +of ties, the old "first matched" rule applies. + +*** A file name handler can declare which operations it handles. + +You do this by putting an `operation' property on the handler name +symbol. The property value should be a list of the operations that +the handler really handles. It won't be called for any other +operations. + +This is useful for autoloaded handlers, to prevent them from being +autoloaded when not really necessary. + +*** The function `make-auto-save-file-name' is now handled by file +name handlers. This will be exploited for remote files mainly. + +*** The function `file-name-completion' accepts an optional argument +PREDICATE, and rejects completion candidates that don't satisfy PREDICATE. + +*** The new primitive `set-file-times' sets a file's access and +modification times. Magic file name handlers can handle this +operation. + +** Input changes: + +*** Functions `y-or-n-p', `read-char', `read-key-sequence' and the like, that +display a prompt but don't use the minibuffer, now display the prompt +using the text properties (esp. the face) of the prompt string. + +*** The functions `read-event', `read-char', and `read-char-exclusive' +have a new optional argument SECONDS. If non-nil, this specifies a +maximum time to wait for input, in seconds. If no input arrives after +this time elapses, the functions stop waiting and return nil. + +*** An interactive specification can now use the code letter `U' to get +the up-event that was discarded in case the last key sequence read for a +previous `k' or `K' argument was a down-event; otherwise nil is used. + +*** The new interactive-specification `G' reads a file name +much like `F', but if the input is a directory name (even defaulted), +it returns just the directory name. + +*** (while-no-input BODY...) runs BODY, but only so long as no input +arrives. If the user types or clicks anything, BODY stops as if a +quit had occurred. `while-no-input' returns the value of BODY, if BODY +finishes. It returns nil if BODY was aborted by a quit, and t if +BODY was aborted by arrival of input. + +*** `recent-keys' now returns the last 300 keys. + +** Minibuffer changes: + +*** The new function `minibufferp' returns non-nil if its optional +buffer argument is a minibuffer. If the argument is omitted, it +defaults to the current buffer. + +*** New function `minibuffer-selected-window' returns the window which +was selected when entering the minibuffer. + +*** The `read-file-name' function now takes an additional argument which +specifies a predicate which the file name read must satisfy. The +new variable `read-file-name-predicate' contains the predicate argument +while reading the file name from the minibuffer; the predicate in this +variable is used by read-file-name-internal to filter the completion list. + +*** The new variable `read-file-name-function' can be used by Lisp code +to override the built-in `read-file-name' function. + +*** The new variable `read-file-name-completion-ignore-case' specifies +whether completion ignores case when reading a file name with the +`read-file-name' function. + +*** The new function `read-directory-name' is for reading a directory name. + +It is like `read-file-name' except that the defaulting works better +for directories, and completion inside it shows only directories. + +*** The new variable `history-add-new-input' specifies whether to add new +elements in history. If set to nil, minibuffer reading functions don't +add new elements to the history list, so it is possible to do this +afterwards by calling `add-to-history' explicitly. + +** Completion changes: + +*** The new function `minibuffer-completion-contents' returns the contents +of the minibuffer just before point. That is what completion commands +operate on. + +*** The functions `all-completions' and `try-completion' now accept lists +of strings as well as hash-tables additionally to alists, obarrays +and functions. Furthermore, the function `test-completion' is now +exported to Lisp. The keys in alists and hash tables can be either +strings or symbols, which are automatically converted with to strings. + +*** The new macro `dynamic-completion-table' supports using functions +as a dynamic completion table. + + (dynamic-completion-table FUN) + +FUN is called with one argument, the string for which completion is required, +and it should return an alist containing all the intended possible +completions. This alist can be a full list of possible completions so that FUN +can ignore the value of its argument. If completion is performed in the +minibuffer, FUN will be called in the buffer from which the minibuffer was +entered. `dynamic-completion-table' then computes the completion. + +*** The new macro `lazy-completion-table' initializes a variable +as a lazy completion table. + + (lazy-completion-table VAR FUN) + +If the completion table VAR is used for the first time (e.g., by passing VAR +as an argument to `try-completion'), the function FUN is called with no +arguments. FUN must return the completion table that will be stored in VAR. +If completion is requested in the minibuffer, FUN will be called in the buffer +from which the minibuffer was entered. The return value of +`lazy-completion-table' must be used to initialize the value of VAR. + +** Abbrev changes: + +*** `define-abbrev' now accepts an optional argument SYSTEM-FLAG. + +If non-nil, this marks the abbrev as a "system" abbrev, which means +that it won't be stored in the user's abbrevs file if he saves the +abbrevs. Major modes that predefine some abbrevs should always +specify this flag. + +*** The new function `copy-abbrev-table' copies an abbrev table. + +It returns a new abbrev table that is a copy of a given abbrev table. + +** Enhancements to keymaps. + +*** Cleaner way to enter key sequences. + +You can enter a constant key sequence in a more natural format, the +same one used for saving keyboard macros, using the macro `kbd'. For +example, + +(kbd "C-x C-f") => "\^x\^f" + +Actually, this format has existed since Emacs 20.1. + +*** Interactive commands can be remapped through keymaps. + +This is an alternative to using `defadvice' or `substitute-key-definition' +to modify the behavior of a key binding using the normal keymap +binding and lookup functionality. + +When a key sequence is bound to a command, and that command is +remapped to another command, that command is run instead of the +original command. + +Example: +Suppose that minor mode `my-mode' has defined the commands +`my-kill-line' and `my-kill-word', and it wants C-k (and any other key +bound to `kill-line') to run the command `my-kill-line' instead of +`kill-line', and likewise it wants to run `my-kill-word' instead of +`kill-word'. + +Instead of rebinding C-k and the other keys in the minor mode map, +command remapping allows you to directly map `kill-line' into +`my-kill-line' and `kill-word' into `my-kill-word' using `define-key': + + (define-key my-mode-map [remap kill-line] 'my-kill-line) + (define-key my-mode-map [remap kill-word] 'my-kill-word) + +When `my-mode' is enabled, its minor mode keymap is enabled too. So +when the user types C-k, that runs the command `my-kill-line'. + +Only one level of remapping is supported. In the above example, this +means that if `my-kill-line' is remapped to `other-kill', then C-k still +runs `my-kill-line'. + +The following changes have been made to provide command remapping: + +- Command remappings are defined using `define-key' with a prefix-key + `remap', i.e. `(define-key MAP [remap CMD] DEF)' remaps command CMD + to definition DEF in keymap MAP. The definition is not limited to + another command; it can be anything accepted for a normal binding. + +- The new function `command-remapping' returns the binding for a + remapped command in the current keymaps, or nil if not remapped. + +- `key-binding' now remaps interactive commands unless the optional + third argument NO-REMAP is non-nil. + +- `where-is-internal' now returns nil for a remapped command (e.g. + `kill-line', when `my-mode' is enabled), and the actual key binding for + the command it is remapped to (e.g. C-k for my-kill-line). + It also has a new optional fifth argument, NO-REMAP, which inhibits + remapping if non-nil (e.g. it returns "C-k" for `kill-line', and + "" for `my-kill-line'). + +- The new variable `this-original-command' contains the original + command before remapping. It is equal to `this-command' when the + command was not remapped. + +*** The definition of a key-binding passed to define-key can use XEmacs-style +key-sequences, such as [(control a)]. + +*** New keymaps for typing file names + +Two new keymaps, `minibuffer-local-filename-completion-map' and +`minibuffer-local-must-match-filename-map', apply whenever +Emacs reads a file name in the minibuffer. These key maps override +the usual binding of SPC to `minibuffer-complete-word' (so that file +names with embedded spaces could be typed without the need to quote +the spaces). + +*** New function `current-active-maps' returns a list of currently +active keymaps. + +*** New function `describe-buffer-bindings' inserts the list of all +defined keys and their definitions. + +*** New function `keymap-prompt' returns the prompt string of a keymap. + +*** If text has a `keymap' property, that keymap takes precedence +over minor mode keymaps. + +*** The `keymap' property now also works at the ends of overlays and +text properties, according to their stickiness. This also means that it +works with empty overlays. The same hold for the `local-map' property. + +*** `key-binding' will now look up mouse-specific bindings. The +keymaps consulted by `key-binding' will get adapted if the key +sequence is started with a mouse event. Instead of letting the click +position be determined from the key sequence itself, it is also +possible to specify it with an optional argument explicitly. + +*** `define-key-after' now accepts keys longer than 1. + +*** (map-keymap FUNCTION KEYMAP) applies the function to each binding +in the keymap. + +*** New variable `emulation-mode-map-alists'. + +Lisp packages using many minor mode keymaps can now maintain their own +keymap alist separate from `minor-mode-map-alist' by adding their +keymap alist to this list. + +*** Dense keymaps now handle inheritance correctly. + +Previously a dense keymap would hide all of the simple-char key +bindings of the parent keymap. + +** Enhancements to process support + +*** Adaptive read buffering of subprocess output. + +On some systems, when Emacs reads the output from a subprocess, the +output data is read in very small blocks, potentially resulting in +very poor performance. This behavior can be remedied to some extent +by setting the new variable `process-adaptive-read-buffering' to a +non-nil value (the default), as it will automatically delay reading +from such processes, allowing them to produce more output before +Emacs tries to read it. + +*** Processes now have an associated property list where programs can +maintain process state and other per-process related information. + +Use the new functions `process-get' and `process-put' to access, add, +and modify elements on this property list. Use the new functions +`process-plist' and `set-process-plist' to access and replace the +entire property list of a process. + +*** Function `list-processes' now has an optional argument; if non-nil, +it lists only the processes whose query-on-exit flag is set. + +*** New fns `set-process-query-on-exit-flag' and `process-query-on-exit-flag'. + +These replace the old function `process-kill-without-query'. That +function is still supported, but new code should use the new +functions. + +*** The new function `call-process-shell-command'. + +This executes a shell command synchronously in a separate process. + +*** The new function `process-file' is similar to `call-process', but +obeys file handlers. The file handler is chosen based on +`default-directory'. + +*** Function `signal-process' now accepts a process object or process +name in addition to a process id to identify the signaled process. + +*** Function `accept-process-output' has a new optional fourth arg +JUST-THIS-ONE. If non-nil, only output from the specified process +is handled, suspending output from other processes. If value is an +integer, also inhibit running timers. This feature is generally not +recommended, but may be necessary for specific applications, such as +speech synthesis. + +*** A process filter function gets the output as multibyte string +if the process specifies t for its filter's multibyteness. + +That multibyteness is decided by the value of +`default-enable-multibyte-characters' when the process is created, and +you can change it later with `set-process-filter-multibyte'. + +*** The new function `set-process-filter-multibyte' sets the +multibyteness of the strings passed to the process's filter. + +*** The new function `process-filter-multibyte-p' returns the +multibyteness of the strings passed to the process's filter. + +*** If a process's coding system is `raw-text' or `no-conversion' and its +buffer is multibyte, the output of the process is at first converted +to multibyte by `string-to-multibyte' then inserted in the buffer. +Previously, it was converted to multibyte by `string-as-multibyte', +which was not compatible with the behavior of file reading. + +** Enhanced networking support. + +*** The new `make-network-process' function makes network connections. +It allows opening of stream and datagram connections to a server, as well as +create a stream or datagram server inside Emacs. + +- A server is started using :server t arg. +- Datagram connection is selected using :type 'datagram arg. +- A server can open on a random port using :service t arg. +- Local sockets are supported using :family 'local arg. +- IPv6 is supported (when available). You may explicitly select IPv6 + using :family 'ipv6 arg. +- Non-blocking connect is supported using :nowait t arg. +- The process' property list can be initialized using :plist PLIST arg; + a copy of the server process' property list is automatically inherited + by new client processes created to handle incoming connections. + +To test for the availability of a given feature, use featurep like this: + (featurep 'make-network-process '(:type datagram)) + (featurep 'make-network-process '(:family ipv6)) + +*** The old `open-network-stream' now uses `make-network-process'. + +*** `process-contact' has an optional KEY argument. + +Depending on this argument, you can get the complete list of network +process properties or a specific property. Using :local or :remote as +the KEY, you get the address of the local or remote end-point. + +An Inet address is represented as a 5 element vector, where the first +4 elements contain the IP address and the fifth is the port number. + +*** New functions `stop-process' and `continue-process'. + +These functions stop and restart communication through a network +connection. For a server process, no connections are accepted in the +stopped state. For a client process, no input is received in the +stopped state. + +*** New function `format-network-address'. + +This function reformats the Lisp representation of a network address +to a printable string. For example, an IP address A.B.C.D and port +number P is represented as a five element vector [A B C D P], and the +printable string returned for this vector is "A.B.C.D:P". See the doc +string for other formatting options. + +*** New function `network-interface-list'. + +This function returns a list of network interface names and their +current network addresses. + +*** New function `network-interface-info'. + +This function returns the network address, hardware address, current +status, and other information about a specific network interface. + +*** New functions `process-datagram-address', `set-process-datagram-address'. + +These functions are used with datagram-based network processes to get +and set the current address of the remote partner. + +*** Deleting a network process with `delete-process' calls the sentinel. + +The status message passed to the sentinel for a deleted network +process is "deleted". The message passed to the sentinel when the +connection is closed by the remote peer has been changed to +"connection broken by remote peer". + +** Using window objects: + +*** You can now make a window as short as one line. + +A window that is just one line tall does not display either a mode +line or a header line, even if the variables `mode-line-format' and +`header-line-format' call for them. A window that is two lines tall +cannot display both a mode line and a header line at once; if the +variables call for both, only the mode line actually appears. + +*** The new function `window-inside-edges' returns the edges of the +actual text portion of the window, not including the scroll bar or +divider line, the fringes, the display margins, the header line and +the mode line. + +*** The new functions `window-pixel-edges' and `window-inside-pixel-edges' +return window edges in units of pixels, rather than columns and lines. + +*** New function `window-body-height'. + +This is like `window-height' but does not count the mode line or the +header line. + +*** The new function `adjust-window-trailing-edge' moves the right +or bottom edge of a window. It does not move other window edges. + +*** The new macro `with-selected-window' temporarily switches the +selected window without impacting the order of `buffer-list'. +It saves and restores the current buffer, too. + +*** `select-window' takes an optional second argument NORECORD. + +This is like `switch-to-buffer'. + +*** `save-selected-window' now saves and restores the selected window +of every frame. This way, it restores everything that can be changed +by calling `select-window'. It also saves and restores the current +buffer. + +*** `set-window-buffer' has an optional argument KEEP-MARGINS. + +If non-nil, that says to preserve the window's current margin, fringe, +and scroll-bar settings. + +*** The new function `window-tree' returns a frame's window tree. + +*** The functions `get-lru-window' and `get-largest-window' take an optional +argument `dedicated'. If non-nil, those functions do not ignore +dedicated windows. + +** Customizable fringe bitmaps + +*** There are new display properties, `left-fringe' and `right-fringe', +that can be used to show a specific bitmap in the left or right fringe +bitmap of the display line. + +Format is `display (left-fringe BITMAP [FACE])', where BITMAP is a +symbol identifying a fringe bitmap, either built-in or defined with +`define-fringe-bitmap', and FACE is an optional face name to be used +for displaying the bitmap instead of the default `fringe' face. +When specified, FACE is automatically merged with the `fringe' face. + +*** New buffer-local variables `fringe-indicator-alist' and +`fringe-cursor-alist' maps between logical (internal) fringe indicator +and cursor symbols and the actual fringe bitmaps to be displayed. +This decouples the logical meaning of the fringe indicators from the +physical appearance, as well as allowing different fringe bitmaps to +be used in different windows showing different buffers. + +*** New function `define-fringe-bitmap' can now be used to create new +fringe bitmaps, as well as change the built-in fringe bitmaps. + +*** New function `destroy-fringe-bitmap' deletes a fringe bitmap +or restores a built-in one to its default value. + +*** New function `set-fringe-bitmap-face' specifies the face to be +used for a specific fringe bitmap. The face is automatically merged +with the `fringe' face, so normally, the face should only specify the +foreground color of the bitmap. + +*** New function `fringe-bitmaps-at-pos' returns the current fringe +bitmaps in the display line at a given buffer position. + +** Other window fringe features: + +*** Controlling the default left and right fringe widths. + +The default left and right fringe widths for all windows of a frame +can now be controlled by setting the `left-fringe' and `right-fringe' +frame parameters to an integer value specifying the width in pixels. +Setting the width to 0 effectively removes the corresponding fringe. + +The actual default fringe widths for the frame may deviate from the +specified widths, since the combined fringe widths must match an +integral number of columns. The extra width is distributed evenly +between the left and right fringe. To force a specific fringe width, +specify the width as a negative integer (if both widths are negative, +only the left fringe gets the specified width). + +Setting the width to nil (the default), restores the default fringe +width which is the minimum number of pixels necessary to display any +of the currently defined fringe bitmaps. The width of the built-in +fringe bitmaps is 8 pixels. + +*** Per-window fringe and scrollbar settings + +**** Windows can now have their own individual fringe widths and +position settings. + +To control the fringe widths of a window, either set the buffer-local +variables `left-fringe-width', `right-fringe-width', or call +`set-window-fringes'. + +To control the fringe position in a window, that is, whether fringes +are positioned between the display margins and the window's text area, +or at the edges of the window, either set the buffer-local variable +`fringes-outside-margins' or call `set-window-fringes'. + +The function `window-fringes' can be used to obtain the current +settings. To make `left-fringe-width', `right-fringe-width', and +`fringes-outside-margins' take effect, you must set them before +displaying the buffer in a window, or use `set-window-buffer' to force +an update of the display margins. + +**** Windows can now have their own individual scroll-bar settings +controlling the width and position of scroll-bars. + +To control the scroll-bar of a window, either set the buffer-local +variables `scroll-bar-mode' and `scroll-bar-width', or call +`set-window-scroll-bars'. The function `window-scroll-bars' can be +used to obtain the current settings. To make `scroll-bar-mode' and +`scroll-bar-width' take effect, you must set them before displaying +the buffer in a window, or use `set-window-buffer' to force an update +of the display margins. + +** Redisplay features: + +*** `sit-for' can now be called with args (SECONDS &optional NODISP). + +*** Iconifying or deiconifying a frame no longer makes sit-for return. + +*** New function `redisplay' causes an immediate redisplay if no input is +available, equivalent to (sit-for 0). The call (redisplay t) forces +an immediate redisplay even if input is pending. + +*** New function `force-window-update' can initiate a full redisplay of +one or all windows. Normally, this is not needed as changes in window +contents are detected automatically. However, certain implicit +changes to mode lines, header lines, or display properties may require +forcing an explicit window update. + +*** (char-displayable-p CHAR) returns non-nil if Emacs ought to be able +to display CHAR. More precisely, if the selected frame's fontset has +a font to display the character set that CHAR belongs to. + +Fontsets can specify a font on a per-character basis; when the fontset +does that, this value cannot be accurate. + +*** You can define multiple overlay arrows via the new +variable `overlay-arrow-variable-list'. + +It contains a list of variables which contain overlay arrow position +markers, including the original `overlay-arrow-position' variable. + +Each variable on this list can have individual `overlay-arrow-string' +and `overlay-arrow-bitmap' properties that specify an overlay arrow +string (for non-window terminals) or fringe bitmap (for window +systems) to display at the corresponding overlay arrow position. +If either property is not set, the default `overlay-arrow-string' or +'overlay-arrow-fringe-bitmap' will be used. + +*** New `line-height' and `line-spacing' properties for newline characters + +A newline can now have `line-height' and `line-spacing' text or overlay +properties that control the height of the corresponding display row. + +If the `line-height' property value is t, the newline does not +contribute to the height of the display row; instead the height of the +newline glyph is reduced. Also, a `line-spacing' property on this +newline is ignored. This can be used to tile small images or image +slices without adding blank areas between the images. + +If the `line-height' property value is a positive integer, the value +specifies the minimum line height in pixels. If necessary, the line +height it increased by increasing the line's ascent. + +If the `line-height' property value is a float, the minimum line +height is calculated by multiplying the default frame line height by +the given value. + +If the `line-height' property value is a cons (FACE . RATIO), the +minimum line height is calculated as RATIO * height of named FACE. +RATIO is int or float. If FACE is t, it specifies the current face. + +If the `line-height' property value is a cons (nil . RATIO), the line +height is calculated as RATIO * actual height of the line's contents. + +If the `line-height' value is a cons (HEIGHT . TOTAL), HEIGHT specifies +the line height as described above, while TOTAL is any of the forms +described above and specifies the total height of the line, causing a +varying number of pixels to be inserted after the line to make it line +exactly that many pixels high. + +If the `line-spacing' property value is an positive integer, the value +is used as additional pixels to insert after the display line; this +overrides the default frame `line-spacing' and any buffer local value of +the `line-spacing' variable. + +If the `line-spacing' property is a float or cons, the line spacing +is calculated as specified above for the `line-height' property. + +*** The buffer local `line-spacing' variable can now have a float value, +which is used as a height relative to the default frame line height. + +*** Enhancements to stretch display properties + +The display property stretch specification form `(space PROPS)', where +PROPS is a property list, now allows pixel based width and height +specifications, as well as enhanced horizontal text alignment. + +The value of these properties can now be a (primitive) expression +which is evaluated during redisplay. The following expressions +are supported: + +EXPR ::= NUM | (NUM) | UNIT | ELEM | POS | IMAGE | FORM +NUM ::= INTEGER | FLOAT | SYMBOL +UNIT ::= in | mm | cm | width | height +ELEM ::= left-fringe | right-fringe | left-margin | right-margin + | scroll-bar | text +POS ::= left | center | right +FORM ::= (NUM . EXPR) | (OP EXPR ...) +OP ::= + | - + +The form `NUM' specifies a fractional width or height of the default +frame font size. The form `(NUM)' specifies an absolute number of +pixels. If a symbol is specified, its buffer-local variable binding +is used. The `in', `mm', and `cm' units specifies the number of +pixels per inch, milli-meter, and centi-meter, resp. The `width' and +`height' units correspond to the width and height of the current face +font. An image specification corresponds to the width or height of +the image. + +The `left-fringe', `right-fringe', `left-margin', `right-margin', +`scroll-bar', and `text' elements specify to the width of the +corresponding area of the window. + +The `left', `center', and `right' positions can be used with :align-to +to specify a position relative to the left edge, center, or right edge +of the text area. One of the above window elements (except `text') +can also be used with :align-to to specify that the position is +relative to the left edge of the given area. Once the base offset for +a relative position has been set (by the first occurrence of one of +these symbols), further occurrences of these symbols are interpreted as +the width of the area. + +For example, to align to the center of the left-margin, use + :align-to (+ left-margin (0.5 . left-margin)) + +If no specific base offset is set for alignment, it is always relative +to the left edge of the text area. For example, :align-to 0 in a +header line aligns with the first text column in the text area. + +The value of the form `(NUM . EXPR)' is the value of NUM multiplied by +the value of the expression EXPR. For example, (2 . in) specifies a +width of 2 inches, while (0.5 . IMAGE) specifies half the width (or +height) of the specified image. + +The form `(+ EXPR ...)' adds up the value of the expressions. +The form `(- EXPR ...)' negates or subtracts the value of the expressions. + +*** Normally, the cursor is displayed at the end of any overlay and +text property string that may be present at the current window +position. The cursor can now be placed on any character of such +strings by giving that character a non-nil `cursor' text property. + +*** The display space :width and :align-to text properties are now +supported on text terminals. + +*** Support for displaying image slices + +**** New display property (slice X Y WIDTH HEIGHT) can be used with +an image property to display only a specific slice of the image. + +**** Function `insert-image' has new optional fourth arg to +specify image slice (X Y WIDTH HEIGHT). + +**** New function `insert-sliced-image' inserts a given image as a +specified number of evenly sized slices (rows x columns). + +*** Images can now have an associated image map via the :map property. + +An image map is an alist where each element has the format (AREA ID PLIST). +An AREA is specified as either a rectangle, a circle, or a polygon: +A rectangle is a cons (rect . ((X0 . Y0) . (X1 . Y1))) specifying the +pixel coordinates of the upper left and bottom right corners. +A circle is a cons (circle . ((X0 . Y0) . R)) specifying the center +and the radius of the circle; R can be a float or integer. +A polygon is a cons (poly . [X0 Y0 X1 Y1 ...]) where each pair in the +vector describes one corner in the polygon. + +When the mouse pointer is above a hot-spot area of an image, the +PLIST of that hot-spot is consulted; if it contains a `help-echo' +property it defines a tool-tip for the hot-spot, and if it contains +a `pointer' property, it defines the shape of the mouse cursor when +it is over the hot-spot. See the variable `void-area-text-pointer' +for possible pointer shapes. + +When you click the mouse when the mouse pointer is over a hot-spot, +an event is composed by combining the ID of the hot-spot with the +mouse event, e.g. [area4 mouse-1] if the hot-spot's ID is `area4'. + +*** The function `find-image' now searches in etc/images/ and etc/. +The new variable `image-load-path' is a list of locations in which to +search for image files. The default is to search in etc/images, then +in etc/, and finally in the directories specified by `load-path'. +Subdirectories of etc/ and etc/images are not recursively searched; if +you put an image file in a subdirectory, you have to specify it +explicitly; for example, if an image is put in etc/images/foo/bar.xpm: + + (defimage foo-image '((:type xpm :file "foo/bar.xpm"))) + +Note that all images formerly located in the lisp directory have been +moved to etc/images. + +*** New function `image-load-path-for-library' returns a suitable +search path for images relative to library. This function is useful in +external packages to save users from having to update +`image-load-path'. + +*** The new variable `max-image-size' defines the maximum size of +images that Emacs will load and display. + +*** The new variable `display-mm-dimensions-alist' can be used to +override incorrect graphical display dimensions returned by functions +`display-mm-height' and `display-mm-width'. + +** Mouse pointer features: + +*** The mouse pointer shape in void text areas (i.e. after the end of a +line or below the last line in the buffer) of the text window is now +controlled by the new variable `void-text-area-pointer'. The default +is to use the `arrow' (non-text) pointer. Other choices are `text' +(or nil), `hand', `vdrag', `hdrag', `modeline', and `hourglass'. + +*** The mouse pointer shape over an image can now be controlled by the +:pointer image property. + +*** The mouse pointer shape over ordinary text or images can now be +controlled/overridden via the `pointer' text property. + +** Mouse event enhancements: + +*** All mouse events now include a buffer position regardless of where +you clicked. For mouse clicks in window margins and fringes, this is +a sensible buffer position corresponding to the surrounding text. + +*** Mouse events for clicks on window fringes now specify `left-fringe' +or `right-fringe' as the area. + +*** Mouse events include actual glyph column and row for all event types +and all areas. + +*** Mouse events can now indicate an image object clicked on. + +*** Mouse events include relative X and Y pixel coordinates relative to +the top left corner of the object (image or character) clicked on. + +*** Mouse events include the pixel width and height of the object +(image or character) clicked on. + +*** Function `mouse-set-point' now works for events outside text area. + +*** `posn-point' now returns buffer position for non-text area events. + +*** New function `posn-area' returns window area clicked on (nil means +text area). + +*** New function `posn-actual-col-row' returns the actual glyph coordinates +of the mouse event position. + +*** New functions 'posn-object', 'posn-object-x-y', 'posn-object-width-height'. + +These return the image or string object of a mouse click, the X and Y +pixel coordinates relative to the top left corner of that object, and +the total width and height of that object. + +** Text property and overlay changes: + +*** Arguments for `remove-overlays' are now optional, so that you can +remove all overlays in the buffer with just (remove-overlays). + +*** New variable `char-property-alias-alist'. + +This variable allows you to create alternative names for text +properties. It works at the same level as `default-text-properties', +although it applies to overlays as well. This variable was introduced +to implement the `font-lock-face' property. + +*** New function `get-char-property-and-overlay' accepts the same +arguments as `get-char-property' and returns a cons whose car is the +return value of `get-char-property' called with those arguments and +whose cdr is the overlay in which the property was found, or nil if +it was found as a text property or not found at all. + +*** The new function `remove-list-of-text-properties'. + +It is like `remove-text-properties' except that it takes a list of +property names as argument rather than a property list. + +** Face changes + +*** The variable `facemenu-unlisted-faces' has been removed. +Emacs has a lot more faces than in the past, and nearly all of them +needed to be excluded. The new variable `facemenu-listed-faces' lists +the faces to include in the face menu. + +*** The new face attribute condition `min-colors' can be used to tailor +the face color to the number of colors supported by a display, and +define the foreground and background colors accordingly so that they +look best on a terminal that supports at least this many colors. This +is now the preferred method for defining default faces in a way that +makes a good use of the capabilities of the display. + +*** New function `display-supports-face-attributes-p' can be used to test +whether a given set of face attributes is actually displayable. + +A new predicate `supports' has also been added to the `defface' face +specification language, which can be used to do this test for faces +defined with `defface'. + +*** The special treatment of faces whose names are of the form `fg:COLOR' +or `bg:COLOR' has been removed. Lisp programs should use the +`defface' facility for defining faces with specific colors, or use +the feature of specifying the face attributes :foreground and :background +directly in the `face' property instead of using a named face. + +*** The first face specification element in a defface can specify +`default' instead of frame classification. Then its attributes act as +defaults that apply to all the subsequent cases (and can be overridden +by them). + +*** The function `face-differs-from-default-p' now truly checks +whether the given face displays differently from the default face or +not (previously it did only a very cursory check). + +*** `face-attribute', `face-foreground', `face-background', `face-stipple'. + +These now accept a new optional argument, INHERIT, which controls how +face inheritance is used when determining the value of a face +attribute. + +*** New functions `face-attribute-relative-p' and `merge-face-attribute' +help with handling relative face attributes. + +*** The priority of faces in an :inherit attribute face list is reversed. + +If a face contains an :inherit attribute with a list of faces, earlier +faces in the list override later faces in the list; in previous +releases of Emacs, the order was the opposite. This change was made +so that :inherit face lists operate identically to face lists in text +`face' properties. + +*** The variable `face-font-rescale-alist' specifies how much larger +(or smaller) font we should use. For instance, if the value is +'((SOME-FONTNAME-PATTERN . 1.3)) and a face requests a font of 10 +point, we actually use a font of 13 point if the font matches +SOME-FONTNAME-PATTERN. + +*** On terminals, faces with the :inverse-video attribute are displayed +with swapped foreground and background colors even when one of them is +not specified. In previous releases of Emacs, if either foreground +or background color was unspecified, colors were not swapped. This +was inconsistent with the face behavior under X. + +*** `set-fontset-font', `fontset-info', `fontset-font' now operate on +the default fontset if the argument NAME is nil.. + +** Font-Lock changes: + +*** New special text property `font-lock-face'. + +This property acts like the `face' property, but it is controlled by +M-x font-lock-mode. It is not, strictly speaking, a builtin text +property. Instead, it is implemented inside font-core.el, using the +new variable `char-property-alias-alist'. + +*** font-lock can manage arbitrary text-properties beside `face'. + +**** the FACENAME returned in `font-lock-keywords' can be a list of the +form (face FACE PROP1 VAL1 PROP2 VAL2 ...) so you can set other +properties than `face'. + +**** `font-lock-extra-managed-props' can be set to make sure those +extra properties are automatically cleaned up by font-lock. + +*** jit-lock obeys a new text-property `jit-lock-defer-multiline'. + +If a piece of text with that property gets contextually refontified +(see `jit-lock-defer-contextually'), then all of that text will +be refontified. This is useful when the syntax of a textual element +depends on text several lines further down (and when `font-lock-multiline' +is not appropriate to solve that problem). For example in Perl: + + s{ + foo + }{ + bar + }e + +Adding/removing the last `e' changes the `bar' from being a piece of +text to being a piece of code, so you'd put a `jit-lock-defer-multiline' +property over the second half of the command to force (deferred) +refontification of `bar' whenever the `e' is added/removed. + +*** `font-lock-extend-region-functions' makes it possible to alter the way +the fontification region is chosen. This can be used to prevent rounding +up to whole lines, or to extend the region to include all related lines +of multiline constructs so that such constructs get properly recognized. + +** Major mode mechanism changes: + +*** New variable `magic-mode-alist' determines major mode for a file by +looking at the file contents. It takes precedence over `auto-mode-alist'. + +*** New variable `magic-fallback-mode-alist' determines major mode for a file by +looking at the file contents. It is handled after `auto-mode-alist', +only if `auto-mode-alist' (and `magic-mode-alist') says nothing about the file. + +*** XML or SGML major mode is selected when file starts with an ` ) + (if (boundp 'foo) form +won't produce a warning if it's not defined as a function, and in the +second case, using `foo' as a variable won't produce a warning if it's +unbound. The test must be in exactly one of the above forms (after +macro expansion), but such tests can be nested. Note that `when' and +`unless' expand to `if', but `cond' doesn't. + +*** `(featurep 'xemacs)' is treated by the compiler as nil. This +helps to avoid noisy compiler warnings in code meant to run under both +Emacs and XEmacs and can sometimes make the result significantly more +efficient. Since byte code from recent versions of XEmacs won't +generally run in Emacs and vice versa, this optimization doesn't lose +you anything. + +*** The local variable `no-byte-compile' in Lisp files is now obeyed. + +*** When a Lisp file uses CL functions at run-time, compiling the file +now issues warnings about these calls, unless the file performs +(require 'cl) when loaded. + +** Frame operations: + +*** New functions `frame-current-scroll-bars' and `window-current-scroll-bars'. + +These functions return the current locations of the vertical and +horizontal scroll bars in a frame or window. + +*** The new function `modify-all-frames-parameters' modifies parameters +for all (existing and future) frames. + +*** The new frame parameter `tty-color-mode' specifies the mode to use +for color support on character terminal frames. Its value can be a +number of colors to support, or a symbol. See the Emacs Lisp +Reference manual for more detailed documentation. + +*** When using non-toolkit scroll bars with the default width, +the `scroll-bar-width' frame parameter value is nil. + +** Mode line changes: + +*** New function `format-mode-line'. + +This returns the mode line or header line of the selected (or a +specified) window as a string with or without text properties. + +*** The new mode-line construct `(:propertize ELT PROPS...)' can be +used to add text properties to mode-line elements. + +*** The new `%i' and `%I' constructs for `mode-line-format' can be used +to display the size of the accessible part of the buffer on the mode +line. + +*** Mouse-face on mode-line (and header-line) is now supported. + +** Menu manipulation changes: + +*** To manipulate the File menu using easy-menu, you must specify the +proper name "file". In previous Emacs versions, you had to specify +"files", even though the menu item itself was changed to say "File" +several versions ago. + +*** The dummy function keys made by easy-menu are now always lower case. +If you specify the menu item name "Ada", for instance, it uses `ada' +as the "key" bound by that key binding. + +This is relevant only if Lisp code looks for the bindings that were +made with easy-menu. + +*** `easy-menu-define' now allows you to use nil for the symbol name +if you don't need to give the menu a name. If you install the menu +into other keymaps right away (MAPS is non-nil), it usually doesn't +need to have a name. + +** Mule changes: + +*** Already true in Emacs 21.1, but not emphasized clearly enough: + +Multibyte buffers can now faithfully record all 256 character codes +from 0 to 255. As a result, most of the past reasons to use unibyte +buffers no longer exist. We only know of three reasons to use them +now: + +1. If you prefer to use unibyte text all of the time. + +2. For reading files into temporary buffers, when you want to avoid +the time it takes to convert the format. + +3. For binary files where format conversion would be pointless and +wasteful. + +*** The new variable `auto-coding-functions' lets you specify functions +to examine a file being visited and deduce the proper coding system +for it. (If the coding system is detected incorrectly for a specific +file, you can put a `coding:' tags to override it.) + +*** The new variable `ascii-case-table' stores the case table for the +ascii character set. Language environments (such as Turkish) may +alter the case correspondences of ASCII characters. This variable +saves the original ASCII case table before any such changes. + +*** The new function `merge-coding-systems' fills in unspecified aspects +of one coding system from another coding system. + +*** New coding system property `mime-text-unsuitable' indicates that +the coding system's `mime-charset' is not suitable for MIME text +parts, e.g. utf-16. + +*** New function `decode-coding-inserted-region' decodes a region as if +it is read from a file without decoding. + +*** New CCL functions `lookup-character' and `lookup-integer' access +hash tables defined by the Lisp function `define-translation-hash-table'. + +*** New function `quail-find-key' returns a list of keys to type in the +current input method to input a character. + +*** `set-buffer-file-coding-system' now takes an additional argument, +NOMODIFY. If it is non-nil, it means don't mark the buffer modified. + +** Operating system access: + +*** The new primitive `get-internal-run-time' returns the processor +run time used by Emacs since start-up. + +*** Functions `user-uid' and `user-real-uid' now return floats if the +user UID doesn't fit in a Lisp integer. Function `user-full-name' +accepts a float as UID parameter. + +*** New function `locale-info' accesses locale information. + +*** On MS Windows, locale-coding-system is used to interact with the OS. +The Windows specific variable w32-system-coding-system, which was +formerly used for that purpose is now an alias for locale-coding-system. + +*** New function `redirect-debugging-output' can be used to redirect +debugging output on the stderr file handle to a file. + +** GC changes: + +*** New variable `gc-cons-percentage' automatically grows the GC cons threshold +as the heap size increases. + +*** New variables `gc-elapsed' and `gcs-done' provide extra information +on garbage collection. + +*** The normal hook `post-gc-hook' is run at the end of garbage collection. + +The hook is run with GC inhibited, so use it with care. + +** Miscellaneous: + +*** A number of hooks have been renamed to better follow the conventions: + +`find-file-hooks' to `find-file-hook', +`find-file-not-found-hooks' to `find-file-not-found-functions', +`write-file-hooks' to `write-file-functions', +`write-contents-hooks' to `write-contents-functions', +`x-lost-selection-hooks' to `x-lost-selection-functions', +`x-sent-selection-hooks' to `x-sent-selection-functions', +`delete-frame-hook' to `delete-frame-functions'. + +In each case the old name remains as an alias for the moment. + +*** Variable `local-write-file-hooks' is marked obsolete. + +Use the LOCAL arg of `add-hook'. + +*** New function `x-send-client-message' sends a client message when +running under X. + +* New Packages for Lisp Programming in Emacs 22.1 + +** The new library button.el implements simple and fast `clickable +buttons' in Emacs buffers. Buttons are much lighter-weight than the +`widgets' implemented by widget.el, and can be used by lisp code that +doesn't require the full power of widgets. Emacs uses buttons for +such things as help and apropos buffers. + +** The new library tree-widget.el provides a widget to display a set +of hierarchical data as an outline. For example, the tree-widget is +well suited to display a hierarchy of directories and files. + +** The new library bindat.el provides functions to unpack and pack +binary data structures, such as network packets, to and from Lisp +data structures. + +** master-mode.el implements a minor mode for scrolling a slave +buffer without leaving your current buffer, the master buffer. + +It can be used by sql.el, for example: the SQL buffer is the master +and its SQLi buffer is the slave. This allows you to scroll the SQLi +buffer containing the output from the SQL buffer containing the +commands. + +This is how to use sql.el and master.el together: the variable +sql-buffer contains the slave buffer. It is a local variable in the +SQL buffer. + +(add-hook 'sql-mode-hook + (function (lambda () + (master-mode t) + (master-set-slave sql-buffer)))) +(add-hook 'sql-set-sqli-hook + (function (lambda () + (master-set-slave sql-buffer)))) + +** The new library benchmark.el does timing measurements on Lisp code. + +This includes measuring garbage collection time. + +** The new library testcover.el does test coverage checking. + +This is so you can tell whether you've tested all paths in your Lisp +code. It works with edebug. + +The function `testcover-start' instruments all functions in a given +file. Then test your code. The function `testcover-mark-all' adds +overlay "splotches" to the Lisp file's buffer to show where coverage +is lacking. The command `testcover-next-mark' (bind it to a key!) +will move point forward to the next spot that has a splotch. + +Normally, a red splotch indicates the form was never completely +evaluated; a brown splotch means it always evaluated to the same +value. The red splotches are skipped for forms that can't possibly +complete their evaluation, such as `error'. The brown splotches are +skipped for forms that are expected to always evaluate to the same +value, such as (setq x 14). + +For difficult cases, you can add do-nothing macros to your code to +help out the test coverage tool. The macro `noreturn' suppresses a +red splotch. It is an error if the argument to `noreturn' does +return. The macro `1value' suppresses a brown splotch for its argument. +This macro is a no-op except during test-coverage -- then it signals +an error if the argument actually returns differing values. + + + +---------------------------------------------------------------------- +This file is part of GNU Emacs. + +GNU Emacs is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 3, or (at your option) +any later version. + +GNU Emacs is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
