** 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

Luc Teirlinck committed
184 185 186 187 188 189
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

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 are involved: it copies the text to the

** 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'.

** 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

224
the end of the buffer in that window.  This allows to tail a file:
Richard M. Stallman's avatar

225
just put point at the end of the buffer and it stays there.  This
Luc Teirlinck's avatar

rule applies to file buffers.  For non-file buffers, the behavior may
be mode dependent.

Luc Teirlinck's avatar
Luc Teirlinck committed
229 230 231 232 233
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.

** 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.

254 255 256 257 258 259 260
** 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').

261 262 263 264
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.

265 266 267 268 269
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.

*** Grep commands now have their own submenu and customization group.

*** The new variables `grep-window-height', `grep-auto-highlight', and
`grep-scroll-output' can be used to override the corresponding
compilation mode settings for grep commands.

*** New option `grep-highlight-matches' highlightes 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.

** 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'.

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.

*** Desktop saving is now a minor mode, desktop-save-mode. 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.

*** 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.

*** New customizable variables:
  - desktop-save. Determins whether the desktop should be saved when it is
    killed.
  - desktop-file-name-format.
  - desktop-path. List of directories in which to lookup the desktop file.
  - desktop-locals-to-save.
  - desktop-globals-to-clear.
  - desktop-clear-preserve-buffers-regexp.

*** New command line option --no-desktop

*** New hooks:
  - desktop-after-read-hook run after a desktop is loaded.
  - desktop-no-desktop-file-hook run when no desktop file is found.

** 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

feature.

** On window systems, lines which are exactly as wide as the window

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.

left fringe, but no arrow bitmaps, use ((top . left) (bottom . left)).

** New command `display-local-help' displays any local help at point

same string that would be displayed on mouse-over using the

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.

** New commands `scan-buf-next-region' and `scan-buf-previous-region'

*** The variable `sql-product' controls the highlightng 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

    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.

** 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.

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'
