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.

** Emacs now supports using both X displays and ttys in one session.
|
|
|
|
|
You can also use any number of different ttys.
|
|
|
|
|
|
|
|
|
|
You can test for the presence of this feature in your Lisp code by
|
|
|
|
|
testing for the `multi-tty' feature.

** Emacs comes with a new set of icons for Mac OS X.
|
|
|
|
|
OS-X-style icons (an application icon and a relevant document icon)
|
|
|
|
|
were contributed by Kentaro Ohkouchi.
|
|
|
|
|
Source files for these icons can be found in Emacs.app/Contents/Resources.
|

|
|
|
|
2007-09-10 09:56:11 +00:00
|
|
|
|
** Built-in functions (subr) can now have an interactive specification
|
|
|
|
|
that is not a prompt string. If the `intspec' parameter of a `DEFUN'
|
|
|
|
|
starts with a `(', the string is evaluated as a Lisp form.
|
|
|
|
|
|
|
|
|
|
** set-file-modes is now interactive and can take the mode value in
|
|
|
|
|
symbolic notation thanks to auxiliary functions.
|
|
|
|
|
|
2007-09-07 03:26:06 +00:00
|
|
|
|
** split-window-preferred-function specifies whether display-buffer should
|
|
|
|
|
split windows vertically or horizontally.
|
|
|
|
|
|
2007-08-30 05:09:07 +00:00
|
|
|
|
** Emacsclient has been extended to support opening a new terminal
|
|
|
|
|
frame. Its behavior has been changed to open a new Emacs frame by
|
|
|
|
|
default. Use the -c option to get the old behavior of opening files in
|
|
|
|
|
the currently selected Emacs frame.
|
|
|
|
|
|
2007-08-26 21:08:54 +00:00
|
|
|
|
** The refcards are now shipped as PDF files.
|
|
|
|
|
|
2007-08-22 04:07:50 +00:00
|
|
|
|
** Emacs now supports the SVG image format through librsvg2.
|
|
|
|
|
|
2007-07-07 05:28:29 +00:00
|
|
|
|
** If you set find-file-confirm-nonexistent-file to t, then C-x C-f
|
2007-07-01 01:57:53 +00:00
|
|
|
|
requires confirmation before opening a non-existent file.
|
|
|
|
|
|
2007-06-14 12:12:23 +00:00
|
|
|
|
** If the gpm mouse server is running and t-mouse-mode enabled, Emacs uses a
|
|
|
|
|
Unix socket in a GNU/Linux console to talk to server, rather than faking events
|
|
|
|
|
using the client program mev. This C level approach provides mouse
|
|
|
|
|
highlighting, and help echoing in the minibuffer.
|
|
|
|
|
|
2007-06-22 07:56:38 +00:00
|
|
|
|
** The new variable next-error-recenter specifies how next-error should
|
|
|
|
|
recenter the visited source file. Its value can be a number (for example,
|
|
|
|
|
0 for top line, -1 for bottom line), or nil for no recentering.
|
|
|
|
|
|
2007-09-25 11:31:17 +00:00
|
|
|
|
** The mode-line displays a `@' if the default-directory for the current buffer
|
2007-07-23 21:27:10 +00:00
|
|
|
|
is on a remote machine, or a hyphen otherwise.
|
2007-08-22 20:08:18 +00:00
|
|
|
|
|
2007-10-04 11:25:29 +00:00
|
|
|
|
** The new command balance-windows-area balances windows both vertically
|
2007-07-24 21:45:28 +00:00
|
|
|
|
and horizontally.
|
2007-07-27 06:11:59 +00:00
|
|
|
|
|
|
|
|
|
** The new command close-display-connection can be used to close a connection
|
|
|
|
|
to a remote display, e.g. because the display is about to become unreachable.
|
2007-08-22 20:08:18 +00:00
|
|
|
|
|
|
|
|
|
** The command shell prompts for the default directory, when it is
|
|
|
|
|
called with a prefix, and the default directory is a remote file name.
|
2007-10-04 11:25:29 +00:00
|
|
|
|
This is because some file name handlers (like ange-ftp) are not able to
|
2007-08-22 20:08:18 +00:00
|
|
|
|
run processes remotely.
|
2007-08-28 15:06:43 +00:00
|
|
|
|
|
|
|
|
|
** The new command `display-time-world' starts an updating time display
|
|
|
|
|
using several time zones, in a buffer.

|
|
|
2007-08-16 00:14:21 +00:00
|
|
|
|
** New user option `initial-buffer-choice' specifies what to display
|
|
|
|
|
after starting Emacs: startup screen, *scratch* buffer, visiting a
|
|
|
|
|
file or directory.
|
|
|
|
|
|
2007-09-30 20:43:14 +00:00
|
|
|
|
** New alias `argv' for `command-line-args-left'
|
|
|
|
|
This is a convenience alias, so that one can write `(pop argv)'
|
|
|
|
|
inside of --eval command line arguments in order to access
|
|
|
|
|
following arguments.

|
|
|

** Minibuffer changes:
|
|
|
|
|
|
|
|
|
|
*** isearch started in the minibuffer searches in the minibuffer history.
|
|
|
|
|
Reverse isearch commands (C-r, C-M-r) search in previous minibuffer
|
|
|
|
|
history elements, and forward isearch commands (C-s, C-M-s) search in
|
|
|
|
|
next history elements. When the reverse search reaches the first history
|
|
|
|
|
element, it wraps to the last history element, and the forward search
|
|
|
|
|
wraps to the first history element. When the search is terminated, the
|
|
|
|
|
history element containing the search string becomes the current.

** The package doc-view.el has been added. It supports viewing of PDF,
|
|
|
|
|
PostScript and DVI documents inside an Emacs buffer by converting the

If `default-directory' is a remote file name, subprocesses are started

2007-07-29 09:18:15 +00:00

** IPv6 is supported on MS-Windows.
|
|
|
|
|
Emacs now supports IPv6 on Windows XP and later, and earlier versions
|
|
|
|
|
of Windows with third party IPv6 stacks installed. Previously IPv6 was
|
|
|
|
|
supported on other platforms, but not on Windows due to using the winsock
|
|
|
|
|
1.1 header file, even though Emacs was linking to the winsock 2 library.

** New keymap `input-decode-map' overrides like key-translation-map, but
|
|
|
|
|
applies before function-key-map. Also it is terminal-local contrary to
|
|
|
|
|
key-translation-map. Terminal-specific key-sequences are generally added to
|
|
|
|
|
this map rather than to function-key-map now.
|
|
|
|
|
|
2007-08-30 05:09:07 +00:00

** Changes related to multiple tty support.
|
|
|
|
|
|
2007-08-31 07:00:18 +00:00
|
|
|
|
*** $TERM is now set to `dumb' for subprocesses. If you want to know the
|
|
|
|
|
$TERM inherited by Emacs you will have to look inside initial-environment.
|
|
|
|
|
|
2007-09-21 07:21:02 +00:00
|
|
|
|
*** $DISPLAY is now dynamically inherited from the frame's `display'.
|
|
|
|
|
|
2007-08-30 05:09:07 +00:00
|
|
|
|
*** The `window-system' variable has been made frame-local. The new
|
|
|
|
|
`initial-window-system' variable contains the `window-system' value
|
|
|
|
|
for the first frame.
|
|
|
|
|
|
|
|
|
|
*** You can specify a terminal device (`tty' parameter) and a terminal
|
|
|
|
|
type (`tty-type' parameter) to `make-terminal-frame'.
|
|
|
|
|
|
|
|
|
|
*** The new function `make-frame-on-tty' allows you to create a new
|
|
|
|
|
frame on another tty device interactively.
|
|
|
|
|
|
|
|
|
|
*** The function `make-frame-on-display' now works during a tty
|
|
|
|
|
session, and `make-frame-on-tty' works during a graphical session.
|
|
|
|
|
|
2007-08-30 19:27:43 +00:00
|
|
|
|
*** New functions: `delete-tty', `suspend-tty', `resume-tty'.

|
|
|
|
|
2007-09-22 19:29:31 +00:00
|
|
|
|
*** A new data type for terminals with functions: `get-device-terminal',
|
|
|
|
|
`terminal-parameters', `terminal-parameter', `set-terminal-parameter'.
|
2007-08-30 05:09:07 +00:00

|
|
|
|
2007-09-10 10:55:24 +00:00
|

*** New hooks: `suspend-tty-functions' and `resume-tty-functions'
|
2007-09-04 15:44:11 +00:00
|
|
|
|
are called after a tty frame has been suspended or resumed,
|
2007-10-04 11:25:29 +00:00
|
|
|
|
respectively. The functions are called with the terminal id of the frame
|
2007-09-04 15:44:11 +00:00
|
|
|
|
being suspended/resumed as a parameter.
|
|
|
|
|
|
2007-08-30 19:27:43 +00:00
|

*** New functions: `environment', `let-environment'.
|
|
|
|
|
|
2007-10-09 05:05:39 +00:00
|
|
|
|
*** New variable: `local-function-key-map'.
|
|
|
|
|
This in addition to the global function-key-map variable that already existed.
|
2007-08-30 19:27:43 +00:00
|
|
|
|
|
2007-08-31 04:43:18 +00:00

*** `initial-environment' holds the environment inherited from Emacs's parent.
|
|
|

2007-08-30 05:09:07 +00:00
|
|
|

*** The `keyboard-translate-table' variable and the terminal and
|
|
|
|
|
keyboard coding systems have been made terminal-local.
|
|
|
|
|
|
2007-10-09 16:02:33 +00:00
|
|
|
|
*** In addition to the global function-key-map, Emacs has terminal-local
|
|
|
|
|
local-function-key-map variables, and uses them instead of the
|
2007-08-30 05:09:07 +00:00
|
|
|
|
global keymaps to set up translations and function key sequences
|
|
|
|
|
relevant to a specific terminal device.

** You can now also pass the value of the `invisible' property to invisible-p
|
|
|
|
|
to check whether it would cause the text to be invisible. Convenient when
|
|
|
|
|
checking invisibility of text which has no buffer position
|
|
|
|
|
(e.g. in before/after-strings).

** In `condition-case', a handler can specify "let the debugger run first".
|
|
|
|
|
|
|
|
|
|
You do this by writing `debug' in the list of conditions to be handled,

like this:

`confirm-only'.

|
|
|
|

as its frame.

** The new function `split-string-and-unquote' does (what?)

** The new function `start-file-process is similar to `start-process',
|
|
|
|
|
but obeys file handlers. The file handler is chosen based on
|
2007-07-24 20:40:26 +00:00
|
|
|
|
`default-directory'. The functions `start-file-process-shell-command'
|
|
|
|
|
and `process-file-shell-command' are also new; they call internally
|
|
|
|
|
`start-file-process and `process-file', respectively.

** `file-remote-p' has new optional parameters IDENTIFICATION and CONNECTED.
|
|
|
|

IDENTIFICATION specifies which part of the remote identifier has to be

`interactive-form' symbol property. Mostly useful to add complex interactive

forms to subroutines.
