** 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
152 153 154 155 156 157
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

159 160 161 162 163 164 165
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
Luc Teirlinck's avatar
Luc Teirlinck committed

`kill-region' if read-only are involved: it copies the text to the
kill-ring, but does not delete it.

** When used interactively, `format-write-file' now asks for confirmation
before overwriting an existing file, unless a prefix argument is

** 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

the end of the buffer in that window.  This allows to tail a file:

193
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
197 198 199 200 201
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.

222 223 224 225 226 227 228
** 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').

229 230 231 232
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.

233 234 235 236 237
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.

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.

** Desktop package

*** 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.

** 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.

** 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

303 304 305 306 307 308 309 310 311
** 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' may be set to nil to
revert to the old behaviour of continuing such lines.

312 313 314 315
** The buffer boundaries (i.e. first and last line in the buffer) may
now be marked with angle bitmaps in the fringes.  In addition, up and
down arrow bitmaps may be shown at the top and bottom of the left or
right fringe if the window can be scrolled in either direction.
316 317

This behavior is activated by setting the buffer-local variable
318 319 320 321 322 323 324 325 326 327
`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.  Any other non-nil value
causes the bitmap on the top line to be displayed in the left fringe,
and the bitmap on the bottom line in the right fringe.

If value is a cons (ANGLES . ARROWS), the car specifies the position
of the angle bitmaps, and the cdr specifies the position of the arrow
328
bitmaps.
329 330 331 332

For example, (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
333
no arrow bitmaps, use (left . nil).

** 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 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.

** New commands `scan-buf-next-region' and `scan-buf-previous-region'
move to the start of the next (previous, respectively) region with
non-nil help-echo property and display any help found there in the
echo area, using `display-local-help'.

** sql changes.

*** 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

The current product name will be shown on the mode line following the
SQL mode indicator.

your .emacs will no longer establish the default highlighting -- Use
`sql-product' to accomplish this.

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.

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.

*** Search for source files using jdb classpath and class

    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.

*** 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).

*** 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.

  Added 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
