** The commands copy-file, rename-file, make-symbolic-link and
add-name-to-file, when given a directory as the "new name" argument,
convert it to a file name by merging in the within-directory part of
the existing file's name.  (This is the same convention that shell
commands cp, mv, and ln follow.)  Thus, M-x copy-file RET ~/foo RET
/tmp RET copies ~/foo to /tmp/foo.

** You can now follow links by clicking Mouse-1 on the link.
171

172 173
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
174
click for both purposes, depending on whether you click outside or
175 176
inside a link.  Now the behavior of a Mouse-1 click has been changed
to match this context-sentitive dual behavior.
177

178
Depending on the current mode, a Mouse-2 click in Emacs may do much
179
more than just follow a link, so the new Mouse-1 behavior is only
180
activated for modes which explicitly mark a clickable text as a "link"
181
(see the new function `mouse-on-link-p' for details).  The Lisp
182
packages that are included in release 22.1 have been adapted to do
183 184
this, but external packages may not yet support this.  However, there
is no risk in using such packages, as the worst thing that could
185
happen is that you get the original Mouse-1 behavior when you click
186 187
on a link, which typically means that you set point where you click.

188 189 190
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
191 192
you release it).

193
Dragging the Mouse-1 inside a link still performs the original
194 195
drag-mouse-1 action, typically copy the text.

Kim F. Storm's avatar
Kim F. Storm committed
196 197
You can customize the new Mouse-1 behavior via the new user options
`mouse-1-click-follows-link' and `mouse-1-click-in-non-selected-windows'.

** 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.

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

controlled with the new user option `ielm-prompt-read-only', which

301 302 303 304 305 306
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

If you are sure that the file will only change by growing at the end,

`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.

** 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').

388 389 390 391
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.

392 393 394 395 396
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.

By default, untranslatable utf-8 sequences are simply composed into
single quasi-characters.  User option `utf-translate-cjk-mode' (it is
turned on by default) arranges to translate many utf-8 CJK character
sequences into real Emacs characters in a similar way to the Mule-UCS
system.  As this loads a fairly big data on demand, people who are not
interested in CJK characters may want to customize it to nil.

You can augment/amend the CJK translation via hash tables
`ucs-mule-cjk-to-unicode' and `ucs-unicode-to-mule-cjk'.  The utf-8

** 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.
