* Installation Changes in Emacs 24.4
25 26 27 28 29 30

** Emacs can be compiled with POSIX ACL support.
This happens by default if a suitable support library is found at
build time, like libacl on GNU/Linux.  To prevent this, use the
configure option `--without-acl'.

+++
** `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.

41 42 43 44
+++
** `eval-defun' on an already defined defcustom calls the :set function,
if there is one.

45 46 47 48
** 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.

49 50 51
** `initial-buffer-choice' can now specify a function to set up the
initial buffer.

52 53 54 55 56
** 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
57 58 59
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.

69 70 71 72
** Battery

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

73 74 75 76 77 78 79
** cl-lib

*** New macro cl-tagbody.

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

80 81 82 83 84 85 86 87 88 89 90 91 92 93
** 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.

94 95 96 97 98 99 100 101 102 103 104
** 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.

** Icomplete is a bit more like IDO.
*** key bindings to navigate through and select the completions.
*** The icomplete-separator is customizable, and its default has changed.
*** Removed icomplete-show-key-bindings.

105 106 107 108 109
** Isearch

*** `C-x 8 RET' in Isearch mode reads a character by its Unicode name
and adds it to the search string.

** MH-E has been updated to MH-E version 8.4.
See MH-E-NEWS for details.

113 114 115 116 117 118 119 120
---
** The unrmail command converts from BABYL to mboxrd rather than mboxo.
Customize `unrmail-mbox-format' to change this.

---
** Similarly, customize `rmail-mbox-format' to influence some minor aspects
of how Rmail displays non-MIME messages.

121 122 123
+++
** New function `ses-rename-cell' to give SES cells arbitrary names.

124 125 126 127 128 129 130 131 132
** 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
  (point) when the function is invoked.

133 134 135 136 137
** New command `delete-duplicate-lines' has two types of operation:
when its arg ADJACENT is non-nil (when called interactively with C-u C-u)
it works like the utility `uniq'.  Otherwise by default it deletes
duplicate lines everywhere in the region without regard to adjacency.

138 139 140 141 142
** Tramp
+++
*** New connection method "adb", which allows to access Android
devices by the Android Debug Bridge.  The variable `tramp-adb-sdk-dir'
must be set to the Android SDK installation directory.
143 144 145
+++
*** Handlers for `file-acl' and `set-file-acl' for remote machines
which support POSIX ACLs.
146

147 148 149 150 151
** Woman

*** The commands `woman-default-faces' and `woman-monochrome-faces'
are obsolete.  Customize the `woman-* faces instead.

* New Modes and Packages in Emacs 24.4
160 161 162 163 164 165 166
** New nadvice.el package offering lighter-weight advice facilities.
It is layered as:
- add-function/remove-function which can be used to add/remove code on any
  function-carrying place, such as process-filters or `<foo>-function' hooks.
- advice-add/advice-remove to add/remove a piece of advice on a named function,
  much like `defadvice' does.

167
* Incompatible Lisp Changes in Emacs 24.4
168

169 170 171 172
** 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.

173 174 175 176
** 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.

177 178
** `defadvice' does not honor the `freeze' flag and cannot advise
special-forms any more.
179

180 181 182 183
** `dolist' in lexical-binding mode does not bind VAR in RESULT any more.
VAR was bound to nil which was not tremendously useful and just lead to
spurious warnings about an unused var.

184 185 186 187 188 189
** The return value of `backup-buffer' has changed.
The second argument is no longer an SELinux context, instead it is an
alist of extended attributes as returned by the new function
`file-extended-attributes'.  The attributes can be applied to another
file using `set-file-extended-attributes'.

190
* Lisp changes in Emacs 24.4
191

192 193 194
** Support for filesystem notifications.
Emacs now supports notifications of filesystem changes, such as
creation, modification, and deletion of files.  This requires the
195 196
'inotify' API on GNU/Linux systems.  On MS-Windows systems, this is
supported for Windows XP and newer versions.
197

198 199 200 201 202 203 204 205 206 207
** Face changes

*** The `face-spec-set' is now analogous to `setq' for face specs.
Its third arg now accepts values specifying exactly which face spec to
set (defface, custom, or user spec), and it directly sets the relevant
property using the supplied face spec.

*** Face specs set via Custom themes now replace the `defface' spec
rather than inheriting from it (as do face specs set via Customize).

208
** time-to-seconds is not obsolete any more.
209
** New function special-form-p.
210 211 212
** Docstrings can be made dynamic by adding a `dynamic-docstring-function'
text-property on the first char.

213 214 215
** The `defalias-fset-function' property lets you catch calls to defalias
and redirect them to your own function instead of `fset'.

216 217 218 219 220 221 222 223 224 225 226
** 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'.

227 228 229 230
** The 6th argument to `copy-file' has been renamed to
`preserve-extended-attributes' as it now handles both SELinux context
and ACL entries.

231 232
* Changes in Emacs 24.4 on non-free operating systems

233 234 235 236 237
+++
** 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.

Glenn Morris committed
242 243 244
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.

245
You can explicitly require a specific version by passing

249 250
an appropriate feature provided by GCC since version 4.5.0.

254 255 256 257 258
** New configure option `--enable-gcc-warnings' (for developing/debugging
Emacs).  If building with GCC, this enables compile-time checks that
warn about possibly-questionable C code.  On a recent GNU system there
should be no warnings; on older and on non-GNU systems the generated
warnings may be useful.

** 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.

280 281 282 283
** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and
/usr/pkg/lib to the linker search path.  You must add them yourself if
you want them.

301

302
*** `C-h f' (`describe-function') can now perform autoloading.
303 304 305 306 307 308 309 310 311
When this command is called for an autoloaded function whose docstring
contains a key substitution construct, that function's library is
automatically loaded, so that the documentation can be shown
correctly.  To disable this, set `help-enable-auto-load' to nil.

*** `C-h f' now reports previously-autoloaded functions as "autoloaded",
even after their associated libraries have been loaded (and the
autoloads have been redefined as functions).

312
** ImageMagick
313

314 315
*** Images displayed via ImageMagick now support transparency and the
:background image specification property.
316

317
*** When available, ImageMagick support is automatically enabled.
318 319
It is no longer necessary to call `imagemagick-register-types'
explicitly to install ImageMagick image types; that function is called
320
automatically at startup, or when customizing an imagemagick- option.

321

322
*** Setting `imagemagick-types-inhibit' to t now disables the use of
Glenn Morris's avatar

323 324
ImageMagick to view images.  (You must call `imagemagick-register-types'
afterwards if you do not use customize to change this.)
Glenn Morris's avatar
Glenn Morris committed
325

326
*** The new variable `imagemagick-enabled-types' also affects which
327 328 329
ImageMagick types are treated as images.  The function
`imagemagick-filter-types' returns the list of types that will be
treated as images.
330

331 332 333 334
** Minibuffer

*** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
next and previous path separator, respectively.
335

336 337 338 339 340 341 342 343 344 345 346 347 348 349
*** `minibuffer-electric-default-mode' can shorten "(default ...)" to "[...]"
in minibuffer prompts.  Just set `minibuffer-eldef-shorten-default'
non-nil before enabling the mode.

** Mode line

*** New option `mode-line-default-help-echo' specifies the help text
(shown in a tooltip or in the echo area) for any part of the mode line
that does not have its own specialized help text.

*** You can now click mouse-3 in the coding system indicator to invoke
`set-buffer-file-coding-system'.

** Emacs now generates backtraces on fatal errors.
On encountering a fatal error, Emacs now outputs a textual description
of the fatal signal, and a short backtrace on platforms like glibc
360
that support backtraces.
361

362 363 364 365 366 367 368 369 370 371
** `C-x C-q' is now bound to the new minor mode `read-only-mode'.
This minor mode replaces `toggle-read-only', which is now obsolete.

** Most `y-or-n' prompts now allow you to scroll the selected window.
Typing `C-v' or `M-v' at a y-or-n prompt scrolls forward or backward
respectively, without exiting from the prompt.

** In the Package Menu, newly-available packages are listed as "new",
and sorted above the other "available" packages by default.

*** New binding `M-g TAB' for `move-to-column'.

*** `M-g TAB' (`move-to-column') prompts for a column number if called
interactively with no prefix arg.  Previously, it moved to column 1.

** New option `yank-handled-properties' allows processing of text
properties on yanked text, in ways that are more general than just
removing them (as is done by `yank-excluded-properties').
435 436 437 438 439

466 467 468
`cl-lib' is like the old `cl' except that it uses the namespace cleanly;

use the "cl--" prefix).

470 471 472 473 474
If `cl' provided a feature under the name `foo', then `cl-lib'
provides it under the name `cl-foo' instead; with the exceptions of the
few `cl' definitions that had to use `foo*' to avoid conflicts with
pre-existing Elisp entities.  These have been renamed to `cl-foo'
rather than `cl-foo*'.

In particular, in cl-flet function definitions are lexically scoped,
whereas in flet the scoping is dynamic.

*** `cl-labels' is slightly different from `labels'.

485 486 487 488
The difference is that it relies on the `lexical-binding' machinery
(as opposed to the `lexical-let' machinery used previously) to capture
definitions in closures, so such closures will only work if `lexical-binding'
is in use.

** Python mode

A new version of python.el, which provides several new features, including:
per-buffer shells, better indentation, Python 3 support, and improved
shell-interaction compatible with iPython (and virtually any other
text based shell).

*** Some user options have been replaced/renamed, including (old -> new):
**** python-indent -> python-indent-offset
**** python-guess-indent -> python-indent-guess-indent-offset
**** python-pdbtrack-do-tracking-p -> python-pdbtrack-activate
**** python-use-skeletons -> python-skeleton-autoinsert

540
Comments are always considered as indentation markers.

**** `python-continuation-offset': Indentation is automatically
calculated in a pep8 compliant way depending on the context.

**** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist':
Have no direct mapping as the shell interaction is completely different.

**** `python-python-command', `python-jython-command':
Replaced by `python-shell-interpreter'.

**** `inferior-python-filter-regexp', `python-remove-cwd-from-path',
`python-pdbtrack-minor-mode-string', `python-source-modes':
No longer relevant.

** Docstrings starting with `*' no longer indicate user options.

The function `user-variable-p' is now an obsolete alias for
`custom-variable-p'.

825 826 827 828
** The return values of `defalias', `defun' and `defmacro' have changed,
and are now undefined.  For backwards compatibility, `defun' and
`defmacro' currently return the name of the newly defined
function/macro, but this should not be relied upon.

** `random' by default now returns a different random sequence in
every Emacs run.  Use `(random S)', where S is a string, to set the
832 833 834
random seed to a value based on S, in order to get a repeatable
sequence in later calls.

835 836 837 838
** If the NEWTEXT arg to `replace-match' contains a substring "\?",
that substring is inserted literally even if the LITERAL arg is
non-nil, instead of causing an error to be signaled.

** `select-window' now always makes the window's buffer current.
It does so even if the window was selected before.

842 843 844
** The function `x-select-font' can return a font spec, instead of a
font name as a string.  Whether it returns a font spec or a font name
depends on the graphical library.

** `face-spec-set' no longer sets frame-specific attributes when the
third argument is a frame (that usage was obsolete since Emacs 22.2).

** `set-buffer-multibyte' now signals an error in narrowed buffers.
850

851 852 853 854 855 856
** The CL package's `get-setf-method' function no longer exists.
Generalized variables are now part of core Emacs Lisp, and implemented

define a compatible replacement for `get-setf-method'.  See the file
gv.el for internal details of the new implementation.

`setf' is autoloaded; `push' and `pop' accept generalized variables.

You can define your own generalized variables using `gv-define-simple-setter',
`gv-define-setter', etc.

** Emacs tries to macroexpand interpreted (non-compiled) files during load.
This can significantly speed up execution of non-byte-compiled code,
but can also bump into previously unnoticed cyclic dependencies.
These are generally harmless: they will simply cause the macro calls
to be left for later expansion (as before), but will result in a
warning ("Eager macro-expansion skipped due to cycle") describing the cycle.
You may wish to restructure your code so this does not happen.

** New sampling-based Elisp profiler.
Try M-x profiler-start, do some work, and then call M-x profiler-report.
When finished, use M-x profiler-stop.  The sampling rate can be based on
CPU time or memory allocations.

** `defun' also accepts a (declare DECLS) form, like `defmacro'.
The interpretation of the DECLS is determined by `defun-declarations-alist'.

932 933 934
** New macros `setq-local' and `defvar-local'.

** Face underlining can now use a wave.

More commands use `read-regexp' now to read their regexp arguments.
