Temporary note:
|
|
|
|
|
|
+++ indicates that the appropriate manual has already been updated.
|
|
|
|
|
|
--- means no change in the manuals is called for.
|
|
|
|
|
|
When you add a new item, please add it without either +++ or ---
|
|
|
|
|
|
so we will look at it and add it to the manual.

|
|
|
|
|
|
--with-mmdf, --with-mail-unlink, --with-mailhost.
|

These provide no new functionality, they just remove the need to edit

|
|

|
|
lib-src/Makefile by hand in order to use the associated features.

** Emacs now supports display and editing of bidirectional text.
|
|
|
|
|
|
Warning: This is still very much experimental! The existing support
|
|
|
|
|
|
is minimal, and when it's turned on (see below), many features are
|
|
|
|
|
|
likely to give unexpected results, or break, or even crash! Use at
|
|
|
|
|
|
your own risk!
|
|
|
|
|
|
|
|
|
|
|
|
See the node "Bidirectional Editing" in the Emacs Manual for some
|
|
|
|
|
|
initial documentation.
|
|
|
|
|
|
|
|
|
|
|
|
To turn this on in any given buffer, set the buffer-local variable
|
|
|
|
|
|
`bidi-display-reordering' to a non-nil value. The default is nil.
|
|
|
|
|
|
|
|
|
|
|
|
The buffer-local variable `bidi-paragraph-direction', if non-nil,
|
|
|
|
|
|
forces each paragraph in the buffer to have its base direction
|
|
|
|
|
|
according to the value of this variable. Possible values are
|
|
|
|
|
|
`right-to-left' and `left-to-right'. If the value is nil (the
|
|
|
|
|
|
default), Emacs determines the base direction of each paragraph from
|
|
|
|
|
|
its text, as specified by the Unicode Bidirectional Algorithm.
|
|
|
|
|
|
|
|
|
|
|
|
Reordering of bidirectional text for display in Emacs is a "Full
|
|
|
|
|
|
bidirectionality" class implementation of the Unicode Bidirectional
|
|
|
|
|
|
Algorithm.

** GTK scroll-bars are now placed on the right by default.
|
2010-03-12 23:13:27 +00:00
|
|
|
|
Use `set-scroll-bar-mode' to change this.
|
|
|
|
|
|
|
2010-04-21 16:25:15 +00:00
|
|
|
|
** GTK tool bars can have just text, just images or images and text.
|
|
|
|
|
|
Customize `tool-bar-style´ to choose style. On a Gnome desktop, the default
|
|
|
|
|
|
is taken from the desktop settings.

|
|
|
|
** Lucid menus and dialogs can display antialiased fonts if Emacs is built
|
|
|
|
|
|
with Xft.
|
Lucid menus can now use Xft for fonts.

(parse_xft_settings): Also check for XSETTINGS_FONT_NAME and save that
in current_font.

* xlwmenu.c (xlwmenu_default_font): Make static.

in windows[i].
(openXftFont): New.
(XlwMenuInitialize): Call openXftFont if HAVE_XFT. If mw->menu.font

** Basic SELinux support has been added.
|
|
|
|
|
|
This requires Emacs to be linked with libselinux at build time.
|
|
|
|
|
|
|
|
|
|
|
|
*** Emacs preserves the SELinux file context when backing up or copying files.
|
|
|

|
|
|
|
|
|
|
|
*** The new functions file-selinux-context and set-file-selinux-context
|
|
|
|
|
|

(bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
|
|
|
|
|
|
of buffer at first key-press (instead moves to top/bottom of buffer)
|
|
|
|
|
|
when a new variable `scroll-error-top-bottom' is non-nil.

|
2010-04-05 23:44:24 +00:00

|
|
|

** Customize
|
|
|
|
|
|
|
|

|
|
|
*** Customize buffers now contain a search field.
|
|
|
|
|
|
The search is performed using `customize-apropos'.
|
|
|
|
|
|
To turn off the search field, set custom-search-field to nil .
|
|
|
|
|
|
|
|
|
|
|
|
*** Custom options now start out hidden if at their default values.
|

|
|

|
|
|
|
*** custom-buffer-sort-alphabetically now defaults to t.
|
|
|

|
|

*** The color widget now has a "Choose" button, which allows you to

*** Special markup can be added to log-edit buffers.
|
2010-04-21 02:05:24 +00:00
|
|
|
|
The log-edit buffers are expected to have a format similar to email messages
|
|
|
|
|
|
with headers of the form:
|
|
|
|
|
|
Author: <author of this change>
|
|
|
|
|
|
Summary: <one line summary of this change>
|
|
|
|
|
|
Fixes: <reference to the bug fixed by this change>
|
|
|
|
|
|
Some backends handle some of those headers specially, but any unknown header
|
|
|
|
|
|
is just left as is in the message, so it is not lost.

|
|
|
|
|
|
For example, adding "(diff-mode . ((mode . whitespace)))" to your
