** You can build Emacs with Gtk+ widgets by specifying `--with-x-toolkit=gtk'
-when you run configure. This requires Gtk+ 2.0 or newer. This port
+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 terminal emulation in term.el now uses "eterm-color" as its
terminfo name, since term.el now supports color.
+---
+** Emacs Lisp source files are compressed by default if `gzip' is available.

* Startup Changes in Emacs 22.1
** 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.
+
+++
** The -f option, used from the command line to call a function,
now reads arguments for the function interactively if it is
`inhibit-splash-screen').
+++
-** The default is now to use an bitmap as the icon, so the command-line options
+** The default is now to use a bitmap as the icon, so the command-line options
--icon-type, -i has been replaced with options --no-bitmap-icon, -nbi to turn
the bitmap icon off.
+++
** A prefix argument is no longer required to repeat a jump to a
-previous mark, 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.
+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.
+++
** The info-search bindings on C-h C-f, C-h C-k and C-h C-i
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.
+
+++
** 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.
++++
+** 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".
+
+++
** M-o now is the prefix key for setting text properties;
M-o M-o requests refontification.
On 32bit machines, it is now 256M (i.e. 268435455).
+++
-** 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.
-
-+++
-** 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.
-
-+++
-** line-move-ignore-invisible now defaults to t.
-
-+++
-** 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.
-
-+++
-** `apply-macro-to-region-lines' now operates on all lines that begin
-in the region, rather than on all complete lines in the region.
-
-+++
-** You can now switch buffers in a cyclic order with C-x C-left and
-(prev-buffer) and C-x C-right (next-buffer). C-x left and C-x right
-can be used as well.
+** 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.
+++
** `undo-only' does an undo which does not redo any previous undo.
** M-SPC (just-one-space) when given a numeric argument N
converts whitespace around point to N spaces.
+---
+** 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.
+
---
** New commands to operate on pairs of open and close characters:
`insert-pair', `delete-pair', `raise-sexp'.
----
++++
** New command `kill-whole-line' kills an entire line at once.
By default, it is bound to C-S-<backspace>.
C-h e displays the *Messages* buffer.
+C-h d runs apropos-documentation.
+
C-h followed by a control character is used for displaying files
that do not change:
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, <deleteline>
-
- C-h w and C-h f new-kill-line reports:
new-kill-line is on C-k

*** In processing a local variables list, Emacs strips the prefix and
-suffix are from every line before processing all the lines.
+suffix from every line before processing all the lines.
+
++++
+*** 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, the user 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.
+++
*** find-file-read-only visits multiple files in read-only mode,
** Minibuffer changes:
++++
+*** 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
`auto-hscroll-mode'. The old name is still available as an alias.
---
-*** Moving or scrolling through images (and other lines) taller that
+*** Moving or scrolling through images (and other lines) taller than
the window now works sensibly, by automatically adjusting the window's
vscroll property.
*** The variable `cursor-in-non-selected-windows' can now be set to any
of the recognized cursor types.
++++
+*** On text terminals, the variable `visible-cursor' controls whether Emacs
+uses the "very visible" cursor (the default) or the normal cursor.
+
** New faces:
+++
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.
fontification in Info, remove `turn-on-font-lock' from
`Info-mode-hook'.
-+++
-*** font-lock-lines-before specifies a number of lines before the
-current line that should be refontified when you change the buffer.
-The default value is 1.
-
+++
*** font-lock: in modes like C and Lisp where the fontification assumes that
an open-paren in column 0 is always outside of any string or comment,
ESC, like they do for Gtk+, Mac and W32.

-*** For Gtk+ version 2.4, you can make Emacs use the old file dialog
+*** For the Gtk+ version, you can make Emacs use the old file dialog
by setting the variable `x-use-old-gtk-file-dialog' to t. Default is to use
the new dialog.
*** Custom themes are collections of customize options. Create a

*** The new command `comint-insert-previous-argument' in comint-derived
-modes (shell-mode etc) inserts arguments from previous command lines,
+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.
+++
*** The new command `multi-occur' is just like `occur', except it can
search multiple buffers. There is also a new command
-`multi-occur-by-filename-regexp' which allows you to specify the
-buffers to search by their filename. Internally, Occur mode has been
-rewritten, and now uses font-lock, among other changes.
+`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.
** Grep changes:
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 (rgrep only). Case sensitivitivy
+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'.
+
---
-*** M-x grep provides highlighting support.
+*** 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' highlightes matches in *grep*
+*** 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
** Xterm support:
---
-*** Emacs now responds to mouse-clicks on the mode-line, header-line and
-display margin, when run in an xterm.
+*** 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.

Rcirc is an Internet relay chat (IRC) client. It supports
** Calc is now part of the Emacs distribution.
Calc is an advanced desk calculator and mathematical tool written in
-Emacs Lisp. Its documentation is in a separate manual; within Emacs,

-and can be invoked from a Dired buffer.
+** The tumme.el package allows you to easily view, tag and in other ways
+manipulate image files and their thumbnails, using dired as the main interface.
+Tumme provides functionality to generate simple image galleries.

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 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.
\f
* Changes in Specialized Modes and Packages in Emacs 22.1:
+** Changes in Dired
+
++++
+*** Bindings for Tumme added
+Several new keybindings, all starting with the C-t prefix, have been
+added to Dired. They are all bound to commands in Tumme. 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.
+
+** 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 hearts content, using symmetric
+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.
-*** many substantial fixes and refinements, including:
+*** Default command prefix changed to "\C-c " (control-c space), to avoid
+intruding on user's keybinding space. Customize the
+`allout-command-prefix' variable to your preference.
+
+*** Allout now uses text overlay's `invisible' property (and others) for
+concealed text, instead of selective-display. This simplifies the code, in
+particularly avoiding the need for kludges for isearch dynamic-display,
+discretionary handling of edits of concealed text, undo concerns, etc.
+
+*** Many substantial fixes and refinements, including:
- repaired inhibition of inadvertent edits to concealed text
- repaired retention of topic body hanging indent upon topic depth shifts
- - prevent "containment discontinuities" where a topic is shifted deeper
- than the offspring-depth of its container
- - easy to adopt the distinctive bullet of a topic in a topic created
- relative to it, or select a new one, or use the common topic bullet
- - plain bullets, by default, now alternate between only two characters
- ('.' and ','), yielding less cluttered outlines
- - many internal fixes
- - version number incremented to 2.1
+ - refuse to create "containment discontinuities", where a
+ topic is shifted deeper than the offspring-depth of its' container
+ - bulleting variation is simpler and more accommodating, both in the
+ default behavior and in ability to vary when creating new topics
+ - many internal fixes and refinements
+ - many module and function docstring clarifications
+ - version number incremented to 2.2
** The variable `woman-topic-at-point' was renamed
to `woman-use-topic-at-point' and behaves differently: if this
`scheme-untrace-command' and `scheme-expand-current-form'.
---
-** Makefile mode has submodes for automake, gmake, makepp and BSD make.

+The former two couldn't be differentiated before, and the latter three
are new. Font-locking is robust now and offers new customizable
faces.
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.
+++
** 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.
+
+*** 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-<delete> or C-c <delete>) respectively. These
+commands delete entire blocks of whitespace with a single
+key-sequence. [N.B. "DEL" is the <backspace> 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 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.
+
+*** 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.
+
*** 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
variable font-lock-maximum-decoration.
Note that the most demanding font lock level has been tuned with lazy
-fontification in mind, i.e. there should be a support mode that waits
-with the fontification until the text is actually shown
-(e.g. Just-in-time Lock mode, which is the default, or Lazy Lock
-mode). Fontifying a file with several thousand lines in one go can
-take the better part of a minute.
+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
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 two kinds of doc comment styles are recognized: Suns Javadoc
-and Autodoc which is used in Pike. 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.
+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
are normally placed under the start of the respective pattern, function
definition, or structured statement.
-The predefined indentation 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.
-
-The command C-c C-q (c-indent-defun) hasn't yet been adapted for AWK,
-though in practice it works properly nearly all the time. Should it
-fail, explicitly set the region around the function (using C-u C-SPC:
-C-M-h probably won't work either) then do C-M-\ (indent-region).
+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
idiosyncrasies in AWK mode's font-locking due to the peculiarities of
the AWK language itself.
-**** Comment Commands
-M-; (indent-for-comment) works fine. None of the other CC Mode
-comment formatting commands have yet been adapted for AWK mode.
+**** 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.
-**** Movement Commands
-Most of the movement commands work in AWK mode. The most important
-exceptions are M-a (c-beginning-of-statement) and M-e
-(c-end-of-statement) which haven't yet been adapted.
-
-The notion of "defun" has been augmented to include AWK pattern-action
-pairs. C-M-a (c-awk-beginning-of-defun) and C-M-e (c-awk-end-of-defun)
-recognize these pattern-action pairs, as well as user defined
-functions.
-
-**** Auto-newline Insertion and Clean-ups
-Auto-newline insertion hasn't yet been adapted for AWK. Some of
-the clean-ups can actually convert good AWK code into syntactically
-invalid code. These features are best disabled in AWK buffers.
+**** "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.
*** New syntactic symbols in IDL mode.
The top level constructs "module" and "composition" (from CIDL) are
composition-close, and incomposition.
*** New functions to do hungry delete without enabling hungry delete mode.
-The functions `c-hungry-backspace' and `c-hungry-delete-forward' can be
-bound to keys to get this feature without toggling a 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'.
In some cases there are more than one position given for a syntactic
symbol.
-This change might affect code that call `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.
+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.
Mode with less risk of such problems in the future.
**** New language variable system.
-See the comment blurb near the top of cc-langs.el.
+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
