* Installation Changes in Emacs 24.4
25

26
** Emacs can be compiled with ACL support.
27 28
This happens by default if a suitable support library is found at
build time, like libacl on GNU/Linux.  To prevent this, use the
29
configure option `--disable-acl'.
30

31
** Emacs can be compiled with file notification support.
32 33 34 35
This happens by default if a suitable system library is found at
build time.  To prevent this, use the configure option
`--with-file-notification-no'.  See below for file-notify features.
FIXME?  This feature is not available for the Nextstep port. (?)
36

37 38 39 40
** The configure option `without-compress-info' has been generalized,
and renamed to `without-compress-install'.  It now prevents compression
of _any_ files during installation.

41
** The configure option --with-crt-dir has been removed.
42 43 44
It is no longer needed, as the crt*.o files are no longer linked
specially.

45 46 47
** Directories passed to configure option `--enable-locallisppath' are
no longer created during installation.

48 49
** Emacs can be compiled with zlib support.  If this library is present
(which it normally is on most systems), the function
50 51
`zlib-decompress-region' becomes available, which can decompress gzip-
and zlib-format compressed data.
52

53 54 55 56
---
** Emacs for NS (OSX, GNUStep) can be built with ImageMagick support.
pkg-config is required to find ImageMagick libraries.

57 58 59 60 61
** For OSX >= 10.5, the Core text based font backend from the Mac port is used.
For GNUStep and OSX 10.4 the old backend is used.
To use the old backend by default, do on the command line:
% defaults write org.gnu.Emacs FontBackend ns

65 66 67 68 69 70 71 72 73 74
+++
** When initializing `load-path', an empty element in the EMACSLOADPATH
environment variable (either leading, e.g., ":/foo"; trailing, e.g.,
"/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default
load-path (the one that would have been used if EMACSLOADPATH was unset).
This makes it easier to _extend_ the load-path via EMACSLOADPATH
(previously, EMACSLOADPATH had to specify the complete load-path,
including the defaults).  (In older versions of Emacs, an empty element
was replaced by ".", so use an explicit "." now if that is what you want.)

75 76
+++
** The -L option, which normally prepends its argument to load-path,
77 78
will instead append, if the argument begins with `:' (or `;' on MS Windows;
i.e., `path-separator').
79

80 81 82 83 84 85
+++
** If you use either site-load.el or site-init.el to customize the dumped
Emacs executable, any changes to `load-path' that these files make
will no longer be present after dumping.  To affect a permanent change
to `load-path', use the `--enable-locallisppath' option of `configure'.

89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104
+++
** Emacs now supports menus on text-mode terminals.
If the terminal supports a mouse, clicking on the menu bar, or on
sensitive portions of the mode line or header line, will drop down the
menu defined at that position.  Likewise, clicking C-mouse-2 or
C-mouse-2 or C-mouse-3 on the text area will pop up the menus defined
for those locations.

If the text terminal does not support a mouse, you can activate the
first menu-bar menu by typing F10, which invokes `menu-bar-open'.

If you want the previous behavior, whereby F10 invoked `tmm-menubar',
customize the option `tty-menu-open-use-tmm' to a non-nil value.
(Typing M-` will always invoke `tmm-menubar', even if
`tty-menu-open-use-tmm' is nil.)

105 106
** Key ? also describes prefix bindings like C-h.

107 108 109 110
+++
** `cache-long-line-scans' has been renamed to `cache-long-scans'
because it affects caching of paragraph scanning results as well.

111 112 113 114 115 116 117
+++
** `apropos-variable' is now `apropos-user-option'
`apropos-user-option' shows all user options while `apropos-variable'
shows all variables.  When called with a universal prefix argument,
the two commands swap their behaviors.  When `apropos-do-all' is
non-nil, they output the same results.

118 119 120 121
+++
** `eval-defun' on an already defined defcustom calls the :set function,
if there is one.

122 123 124 125 126 127
** A zero prefix arg of `eval-last-sexp' (`C-x C-e'),
`eval-expression' (`M-:') and `eval-print-last-sexp' (`C-j') inserts
a list with no limit on its length and level (by using nil values of
`print-length' and `print-level'), and inserts additional formats for
integers (octal, hexadecimal, and character).

128 129 130 131
** If the new variable `enable-dir-local-variables' is nil,
directory local variables are ignored.  May be useful for some modes
that want to ignore directory-locals while still respecting file-locals.

132 133 134 135
** The option `set-mark-default-inactive' has been deleted.
This unfinished feature was introduced by accident in Emacs 23.1;
simply disabling Transient Mark mode does the same thing.

136 137 138
** `initial-buffer-choice' can now specify a function to set up the
initial buffer.

139 140 141 142
** The *Messages* buffer is created in a new major mode `messages-buffer-mode',
and read-only.  Code that might create the *Messages* buffer should
call the function `messages-buffer' to do so and set the mode.

143 144 145 146 147 148 149 150
** `remember-notes' creates a buffer whose content is saved on kill-emacs.
You may think of it as a *scratch* buffer whose content is preserved.
In fact, it was designed as a replacement for *scratch* buffer and can
be used that way by setting `initial-buffer-choice' to `remember-notes'
and `remember-notes-buffer-name' to "*scratch*".  Without the second
change, *scratch* buffer will still be there for notes that do not
need to be preserved.

151 152
** `write-region-inhibit-fsync' now defaults to t in batch mode.

153 154 155 156 157
** ACL support has been added.
+++
*** Emacs preserves the ACL entries of files when backing up.
+++
*** New functions `file-acl' and `set-file-acl' get and set the ACL
158 159 160
entries of a file.  On GNU/Linux, the POSIX ACL interface is used via
libacl.  On MS-Windows, the NT Security APIs are used to emulate the
POSIX ACL interfaces.
161

162
** New option `scroll-bar-adjust-thumb-portion'.
163 164 165
Available only on X, this option allows to control over-scrolling
using the scroll bar (i.e. dragging the thumb down even when the end
of the buffer is visible).
166

167 168 169
** New function `add-face-text-property' has been added, which can be
used to conveniently prepend/append new face attributes to text.

170 171
** In compiled Lisp files, the header no longer includes a timestamp.

172 173 174 175 176 177
** Multi-monitor support has been added.

*** New functions `display-monitor-attributes-list' and
`frame-monitor-attributes' can be used to obtain information about
each physical monitor on multi-monitor setups.

178 179 180 181 182 183 184 185
*** The functions `display-pixel-width' and `display-pixel-height' now
behave consistently among the platforms: they return the pixel width
or height for all physical monitors associated with the given display
as just they were on X11.  To get information for each physical
monitor, use the new functions above.  Similar notes also apply to
`x-display-pixel-width', `x-display-pixel-height', `display-mm-width',
`display-mm-height', `x-display-mm-width', and `x-display-mm-height'.

186
** New macro `define-alternatives' can be used to define generic commands.
187 188 189
Generic commands are interactive functions whose implementation can be
selected among several alternatives, as a matter of user preference.

190
** New hooks `focus-in-hook', `focus-out-hook'.
191
These are normal hooks run when an Emacs frame gains or loses input focus.

192

193 194 195 196 197
** The blink cursor stops blinking after 10 blinks (default) on X and NS.
You can change the default by customizing the variable blink-cursor-blinks.
Also timers for blinking are stopped when no blinking is done, so Emacs does
not consume CPU cycles.

198 199 200 201 202
** New command `frameset-to-register' is now bound to `C-x r f', replacing
`frame-configuration-to-register'.  It offers similar functionality, plus
some enhancements, like the ability to restore deleted frames.  Command
`frame-configuration-to-register' is still available, but unbound.

203 204 205
** The command `quail-help' is deleted.  Use `C-h C-\'
(`describe-input-method') instead.

206 207 208
** The default value of `comment-use-global-state' is changed to t,
and this variable has been marked obsolete.

209 210 211 212 213 214
** `fill-single-char-nobreak-p' prevents fill from breaking a line after
a 1-letter word, which is an error according to Polish and
Czech typography rules.  To globally enable this feature, evaluate:

  (add-hook 'fill-nobreak-predicate 'fill-single-char-nobreak-p)

* Editing Changes in Emacs 24.4
217

218 219
** `electric-indent-mode' is enabled by default.

220
** Uniquify is enabled by default with post-forward-angle-brackets style.
221

222
** Command `rectangle-mark-mode' bound to C-x SPC makes a rectangular region.
223 224
Most commands are still unaware of it, but kill/yank do work on the rectangle.

225 226 227
** C-x TAB enters a transient interactive mode.
You can then use the left/right cursor keys to move the block of text.

Xue Fuqiao's avatar
Xue Fuqiao committed
228 229 230
** `tab-stop-list' is now implicitly extended to infinity by repeating
the last step.  Its default value is changed to nil which means a tab
stop every `tab-width' columns.
231

232 233 234 235 236
** `split-window' is no longer a command, just a non-interactive function.
As a command it was a special case of `split-window-below', and as such
superfluous.  After being reimplemented in Lisp, its interactive form
was mistakenly retained.

237 238
** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized',
bound to <f11> and M-<f10>, respectively.
239

240 241 242
** In keymaps where SPC scrolls, S-SPC now scrolls in the reverse direction.
Eg View mode, etc.

243 244 245 246 247 248 249
+++
** New option `visual-order-cursor-movement'.
If this is non-nil, cursor motion with arrow keys will follow the
visual order of characters on the screen: <left> always moves to the
left, <right> always moves to the right, disregarding the surrounding
bidirectional context.

250 251
** All register commands can now show help with preview.

252 253
** New command `kmacro-to-register' to store keyboard macros in registers.

254 255 256 257 258
** Shell Script mode

*** `sh-mode' now has the mode own `add-log-current-defun-function'.
You can pick the name of the function and the variables with `C-x 4 a'.

259

260
* Changes in Specialized Modes and Packages in Emacs 24.4
261

262
** CUA-mode
263
*** CUA-mode was changed to make use of delete-selection-mode and
264 265 266 267
shift-select-mode.  So you can now enable it independently from
transient-mark-mode, delete-selection-mode, and shift-select-mode.
As a result, cua-highlight-region-shift-only is obsolete
(you can disable transient-mark-mode to get the same result).
268
*** CUA's rectangles can now be used via `cua-rectangle-mark-mode'.
269

270
** `delete-selection-mode' can be used without transient-mark-mode.
271

272
** prolog-use-smie has been removed, along with the non-SMIE indentation code.
273

274
** SMIE indentation can be customized via `smie-config'.
Paul Eggert's avatar
Paul Eggert committed
275
The customization can be guessed by Emacs by providing a sample indented
276 277 278 279
file and letting SMIE learn from it.

** sh-script now uses its SMIE indentation algorithm by default.

280 281 282 283 284 285 286 287 288 289 290 291
** `eshell' now supports visual subcommands and options
Eshell has been able to handle "visual" commands (interactive,
non-line oriented commands such as top that require display
capabilities not provided by eshell) by running them in an Emacs
terminal emulator.  See `eshell-visual-commands'.

This feature has been extended to subcommands and options that make a
usually line-oriented command a visual command.  Typical examples are
"git log" and "git <command> --help" which display their output in a
pager by default.  See `eshell-visual-subcommands' and
`eshell-visual-options'.

** If your Emacs is compiled with libxml2 support, you can use the new
built-in web browser `eww'.

295 296 297 298 299 300
** `remember' can now store notes in separates files
You can use the new function `remember-store-in-files' within the
`remember-handler-functions' option.

See `remember-data-directory' and `remember-directory-file-name-format'
for new options related to this function.

326 327
*** `delphi-newline-always-indents' is not supported any more.

328 329
*** `delphi-tab' is gone, replaced by `indent-for-tab-command'.

330 331
** Eldoc Mode works properly in the minibuffer.

332 333
** jit-lock-debug-mode lets you use the debuggers on code run via jit-lock.

334 335 336
** completing-read-multiple's separator can now be a regexp.
The default separator is changed to allow surrounding spaces around the comma.

337 338 339 340 341 342
** The backtrace debugger and local variables:
*** The debugger's `e' command evaluates the code in the context at point.
This includes using the lexical environment at point, which means that
`e' now lets you access lexical variables as well.
*** The backtrace debugger can display local vars with `v'.

343 344 345 346
** Battery

*** Battery information via the BSD `apm' utility is now supported.

347 348 349 350
** Buffer Menu

*** `M-s a C-o' shows lines matching a regexp in marked buffers using Occur.

351 352
** Calendar and Diary

353 354 355 356 357 358 359
*** New faces: `calendar-weekday-header', `calendar-weekend-header',

378

379 380 381
*** `cvs-append-to-ignore' has been renamed to `vc-cvs-append-to-ignore'
because it is moved to vc-cvs.el.

382 383 384 385 386 387 388
** cl-lib

*** New macro cl-tagbody.

+++
*** letf is now just an alias for cl-letf.

389 390 391 392 393 394 395 396 397 398 399 400 401 402
** Calc

*** Calc by default now uses the Gregorian calendar for all dates, and
uses January 1, 1 AD as its day number 1.  Previously Calc used the
Julian calendar for dates before September 14, 1752, and it used
December 31, 1 BC as its day number 1; the new scheme is more
consistent with Calendar's calendrical system and day numbering.

*** The new variable `calc-gregorian-switch' lets you configure the
date when Calc switches from the Julian to the Gregorian calendar.
Nil, the default value, means to always use the Gregorian calendar.
The value (YEAR MONTH DAY) means to start using the Gregorian calendar
on the given date.

403 404
*** Support for ISO 8601 dates.

405 406
** Desktop

407 408
*** `desktop-auto-save-timeout' defines the number of seconds idle time
before auto-save of the desktop.
409

410
*** `desktop-restore-frames', enabled by default, allows saving and
411
restoring the frame/window configuration (frameset).  Additional options
412
`desktop-restore-in-current-display', `desktop-restore-reuses-frames'
413
and `desktop-restore-forces-onscreen' offer further customization.
414

415 416 417 418
** Dired

*** New minor mode `dired-hide-details-mode' hides details.

419 420 421 422 423 424
** ERC

*** New option `erc-accidental-paste-threshold-seconds'.
If set to a number, this can be used to avoid accidentally paste large
amounts of data into the ERC input.

425 426 427 428 429 430 431 432 433 434 435 436 437 438 439 440
** EPA

*** New option `epa-mail-aliases'.

You can set this to a list of alias expansions for keys to use
in `epa-mail-encrypt'.

If one element of the variable's value is ("foo@bar.com" "foo@hello.org"),
that means: when one of the recipients of the message being encrypted
is `foo@bar.com', encrypt the message for `foo@hello.org' instead.

If one element of the variable's value is ("foo@bar.com"),
that means: when one of the recipients of the message being encrypted
is `foo@bar.com', ignore that name as regards encryption.
This is useful to avoid a query when you have no key for that name.

*** New commands `n' (`image-next-file') and `p' (`image-previous-file')
visit the next image file and the previous image file in the same
directory, respectively.

472 473 474 475
*** New commands to show specific frames of multi-frame images.
`f' (`image-next-frame') and `b' (`image-previous-frame') visit the
next or previous frame.  `F' (`image-goto-frame') shows a specific frame.

476 477
*** New commands to speed up, slow down, or reverse animation.

478 479 480 481 482 483
---
*** The command `image-mode-fit-frame' deletes other windows.
When toggling, it restores the frame's previous window configuration.
It also has an optional frame argument, which can be used by Lisp
callers to fit the image to a frame other than the selected frame.

484 485 486 487 488 489
** Info

*** New face `info-index-match' is used to highlight matches in index
entries displayed by `Info-index-next', `Info-virtual-index' and
`info-apropos'.

490 491 492 493 494 495 496 497 498 499
** Hi-Lock

*** New option `hi-lock-auto-select-face'.  When non-nil, hi-lock commands

*** Word search now matches whitespace at the beginning/end
of the search string if it contains leading/trailing whitespace.
In an incremental word search or when using a non-nil LAX argument
of `word-search-regexp', the lax matching can also match part of
the first word (in addition to the lax matching of the last word).
The same rules are now applied to the symbol search with the difference
that it matches symbols, and non-symbol characters between symbols.

** trace-function was largely rewritten.
New features include:
- no prompting for the destination buffer, unless a prefix-arg was used.
- additionally to prompting for a destination buffer, when a prefix-arg is
  used, the user can enter a "context", i.e. Lisp expression whose value at the
  time the function is entered/exited will be printed along with the function
  name and arguments.  Useful to trace the value of (current-buffer) or

- more fine-grained interaction with the Emacs diary, by being able to decide
  for each todo item whether it appears in the Fancy Diary display;
- highly flexible new item insertion and item editing;
- moving items between categories, storing done items in their category or in
  archive files, undoing or unarchiving done items;
- reprioritizing items by inputting a numerical priority;
- extensive customizability of operation and display, including numerous faces.
584
The Todo mode user manual describes all commands and most user options.
585 586 587 588 589 590
To support some of these features, a new file format is used, which is
incompatible with the old format; however, you can convert old todo and done
item files to the new format on initializing the first new todo file, or at any
later time with the provided conversion command.  The old version of
todo-mode.el has been made obsolete and renamed otodo-mode.el.

** `kill-region' lost its `yank-handler' optional argument.

759 760 761
** `(input-pending-p)' no longer runs other timers which are ready to

** `defvar' and `defcustom' in a let-binding affect the "external" default.

764 765 766
** The syntax of ?» and ?« is now punctuation instead of matched parens.
Some languages match those as »...« and others as «...» so better stay neutral.

767 768 769 770
** The default file coding for Emacs Lisp files is now utf-8.
(See file-coding-system-alist.)  In most cases, this change is transparent, but
files that contain unusual characters without specifying an explicit coding
system may fail to load with obscure errors.

** `read-event' does not return decoded chars in ttys any more.
Just as was the case in Emacs-22 and before, decoding of tty input according to
keyboard-coding-system is not performed in read-event any more.  But contrary
to that past, it is still done before input-decode-map/function-key-map/...

785 786
** Removed inhibit-local-menu-bar-menus.

787 788 789 790
** frame-local variables that affect redisplay do not work any more.
More specifically, the redisplay does not bother to check for a frame-local
value when looking up variables.

791 792 793 794
** nil and "unbound" are indistinguishable in symbol-function.
`symbol-function' never signals `void-function' any more.
`fboundp' returns non-nil if the symbol was `fset' to nil.

** Changes in encoding and decoding of text

---
*** New coding-system `prefer-utf-8'.
This is like `undecided' but prefers UTF-8 on decoding if the text to
be decoded does not contain any invalid UTF-8 sequences.  On encoding,
any non-ASCII characters are automatically encoded as UTF-8.

---
*** New attributes of coding-systems whose type is `undecided'.
Two new attributes, `:inhibit-null-byte-detection' and
`:inhibit-iso-escape-detection', determine how to detect encoding of
text that includes null bytes and ISO-2022 escape sequences,
respectively.  Each of these attributes can be either nil, zero, or
t.  If it is t, decoding text ignores null bytes and, respectively,
ISO-2022 sequences.  If it is nil, null bytes cause text to be decoded
with no-conversion and ISO-2022 sequences cause Emacs to assume the
text is encoded in one of the ISO-2022 encodings, such as
iso-2022-7bit.  If the value is zero, Emacs consults the variables
inhibit-null-byte-detection and inhibit-iso-escape-detection, which
see.
The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer
UTF-8 encoding and decoding, whenever possible.

These attributes are only meaningful for coding-systems of type
`undecided'.  (The type of a coding-system is determined by its
`:coding-type' attribute and can be accessed by calling the
`coding-system-type' function.)

text-property on the first char.

** The lock for 'DIR/FILE' is now 'DIR/.#FILE' and may be a regular file.
1018 1019 1020 1021 1022 1023 1024
When you edit DIR/FILE, Emacs normally creates a symbolic link
DIR/.#FILE as a lock that warns other instances of Emacs that DIR/FILE
is being edited.  Formerly, if there was already a non-symlink file
named DIR/.#FILE, Emacs fell back on the lock names DIR/.#FILE.0
through DIR/.#FILE.9.  These fallbacks have been removed, so that
Emacs now no longer locks DIR/FILE in that case.

1025 1026
On file systems that do not support symbolic links, the lock is now a
regular file with contents being what would have been in the symlink.

** The 9th element returned by `file-attributes' is now unspecified.
Formerly, it was t if the file's gid would change if file were deleted
and recreated.  This value has been inaccurate for years on many
platforms, and nobody seems to have noticed or cared.

** The function `file-ownership-preserved-p' now has an optional
argument GROUP which causes it check for file group too.  This can be
used in place of the 9th element of `file-attributes'.

** New functions `group-gid' and `group-real-gid'.

1039 1040 1041 1042
** The 6th argument to `copy-file' has been renamed to
`preserve-extended-attributes' as it now handles both SELinux context
and ACL entries.

1043 1044 1045 1046 1047
** The `common-substring' argument of display-completion-list is obsolete.
Either use `completion-all-completions' which already returns highlighted
strings (including for partial or substring completion) or call
`completion-hilit-commonality' to add the highlight.

* Changes in Emacs 24.4 on Non-Free Operating Systems
1056

1057 1058 1059 1060
** The procedure for building Emacs on MS-Windows has changed.
It is now built by running the same configure script as on all other
platforms.  This requires the MSYS environment and MinGW development
tools.  See the updated instructions in nt/INSTALL for details.
1061 1062 1063 1064 1065 1066 1067 1068 1069 1070 1071 1072 1073

Using the Posix configure script and Makefile's also means a change in
the directory structure of the Emacs installation on Windows.  It is
now the same as on GNU and Unix systems.  In particular, the auxiliary
programs, such as cmdproxy.exe and hexl.exe, are in
libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs
version), version-independent site-lisp is in share/emacs/site-lisp,
version-specific Lisp files are in share/emacs/VERSION/lisp and in
share/emacs/VERSION/site-lisp, Info docs are in share/info, and data
files are in share/emacs/VERSION/etc.  (Emacs knows about all these
directories and will find the files in there automatically; there's no
need to set any variables due to this change.)

** Emacs on Windows 2000 and later can now access files and directories
whose names cannot be encoded in the current system codepage.

The new variable `w32-unicode-filenames' controls this feature: if it
is t, Emacs uses Unicode APIs to pass file names to system calls,
which lifts the limitation of file names to the current locale.

1082 1083 1084 1085 1086
+++
** The "generate a backtrace on fatal error" feature now works on MS Windows.
The backtrace is written to the 'emacs_backtrace.txt' file in the
directory where Emacs was running.

1087 1088 1089 1090 1091 1092
+++
** The variable `buffer-file-type' is no longer supported.
Setting it has no effect, and %t in the mode-line format is ignored.
Likewise, `file-name-buffer-file-type-alist' is now obsolete, and
modifying it has no effect.

1093 1094 1095 1096 1097 1098 1099

** Lock files now work on MS-Windows.
This allows to avoid losing your edits if the same file is being
edited in another Emacs session or by another user.  See the node
"Interlocking" in the Emacs User Manual for the details.  To disable
file locking, customize `create-lockfiles' to nil.

** Improved fullscreen support on Mac OS X.
Both native (>= OSX 10.7) and "old style" fullscreen are supported.
Customize `ns-use-native-fullscreen' to change style.  For >= 10.7
native is the default.

If you don't pass `--with-x-toolkit' to configure, or if you use
`--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try
to build with Gtk+ version 3, and if that fails, try Gtk+ version 2.

** The configure options `--program-prefix', `--program-suffix', and
`--program-transform-name' apply to more than just the installed
binaries.  Now they also affect the man pages, icons, and the
etc/emacs.desktop file; but not the info pages, since this would break
links between the various manuals.
