(Currently this feature is only used on MS Windows.)  You can configure

** You can now follow links by clicking Mouse-1 on the link.
131

132 133
Traditionally, Emacs uses a Mouse-1 click to set point and a Mouse-2
click to follow a link, whereas most other applications use a Mouse-1
134
click for both purposes, depending on whether you click outside or
135 136
inside a link.  Now the behavior of a Mouse-1 click has been changed
to match this context-sentitive dual behavior.
137

138
Depending on the current mode, a Mouse-2 click in Emacs may do much
139
more than just follow a link, so the new Mouse-1 behavior is only
140
activated for modes which explicitly mark a clickable text as a "link"
141
(see the new function `mouse-on-link-p' for details).  The Lisp
142 143 144
packages that are included in release 21.4 have been adapted to do
this, but external packages may not yet support this.  However, there
is no risk in using such packages, as the worst thing that could
145
happen is that you get the original Mouse-1 behavior when you click
146 147
on a link, which typically means that you set point where you click.

148 149 150
If you want to get the original Mouse-1 action also inside a link, you
just need to press the Mouse-1 button a little longer than a normal
click (i.e. press and hold the Mouse-1 button for half a second before
151 152
you release it).

153
Dragging the Mouse-1 inside a link still performs the original
154 155
drag-mouse-1 action, typically copy the text.

156
You can customize the new Mouse-1 behavior via the new user option
157 158
`mouse-1-click-follows-link'.

159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176

** require-final-newline now has two new possible values:

`visit' means add a newline (as an undoable change) if it's needed
when visiting the file.

`visit-save' means add a newline (as an undoable change) if it's
needed when visiting the file, and also add a newline if it's needed
when saving the file.

+++
** The new option mode-require-final-newline controls how certain
major modes enable require-final-newline.  Any major mode that's
designed for a kind of file that should normally end in a newline
sets require-final-newline based on mode-require-final-newline.
So you can customize mode-require-final-newline to control what these
modes do.

** Passing resources on the command line now works on MS Windows.
You can use --xrm to pass resource settings to Emacs, overriding any
existing values.  For example:

  emacs --xrm "Emacs.Background:red" --xrm "Emacs.Geometry:100x20"

will start up Emacs on an initial frame of 100x20 with red background,
irrespective of geometry or background setting on the Windows registry.

function also defines the result format for `eval-expression' (M-:),
`eval-print-last-sexp' (C-j) and some edebug evaluation functions.

** The comint prompt can now be made read-only, using the new user

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's avatar
Luc Teirlinck committed
254 255 256 257 258 259
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

Luc Teirlinck committed
261 262 263 264 265 266 267
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

** 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

293
displayed at the end of a file buffer in any window, it stays at
Luc Teirlinck's avatar

294
the end of the buffer in that window.  This allows to tail a file:
Richard M. Stallman's avatar

295
just put point at the end of the buffer and it stays there.  This
Luc Teirlinck's avatar
Luc Teirlinck committed

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

Luc Teirlinck's avatar
Luc Teirlinck committed
299 300 301 302 303
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.

324 325 326 327 328 329 330
** 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').

331 332 333 334
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.

335 336 337 338 339
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.

*** 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'.

matches, compilation errors, etc.  This minor mode can be toggled with

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

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

your .emacs will no longer establish the default highlighting -- Use

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
