If you are ready to start working on any of these TODO items, we
|
|
|
|
|
appreciate your help; please write to emacs-devel@gnu.org so we can be
|
|
|
|
|
aware that the problem is being addressed, and talk with you how to do
|
2013-02-16 20:24:50 +00:00
|
|
|
|
it best. Also to check that it hasn't been done already, since we
|
|
|
|
|
don't always remember to update this file! It is best to consult
|
|
|
|
|
the latest version of this file in the Emacs source code repository.

As well as the issues listed here, there are bug reports at
|
|
|
|
|
<http://debbugs.gnu.org>. Bugs tagged "easy" ought to be suitable for
|
|
|
|
|
beginners to work on, but unfortunately we are not very good at using
|
|
|
|
|
this tag. Bugs tagged "help" are ones where assistance is required,
|
|
|
|
|
but may be difficult to fix. Bugs with severity "important" or higher
|
|
|
|
|
are the ones we consider more important, but these also may be
|
|
|
|
|
difficult to fix. Bugs with severity "minor" may be simpler, but this
|
|
|
|
|
is not always true.

* Speed up Elisp execution
|
|
|
|
|
** Speed up function calls
|
|
|
|
|
Change src/bytecode.c so that calls from byte-code functions to byte-code
|
|
|
|
|
functions don't go through Ffuncall/funcall_lambda/exec_byte_code but instead
|
|
|
|
|
stay within exec_byte_code.
|
|
|
|
|
|
2015-08-26 21:05:43 +00:00
|
|
|
|
** Add new 'switch' byte-code
|
2014-09-26 22:19:12 +00:00
|
|
|
|
This byte-code would take one argument from the stack (the object to test)
|
|
|
|
|
and one argument from the constant-pool (a switch table, implemented as an
|
2016-11-04 21:50:09 +00:00
|
|
|
|
'eq' hash table) and would jump to the "label" contained in the hash table.
|
2014-09-26 22:19:12 +00:00
|
|
|
|
|
2015-08-26 21:05:43 +00:00
|
|
|
|
Then add a 'case' special-form that can be compiled to this byte-code.
|
2014-09-26 22:19:12 +00:00
|
|
|
|
This would behave just like cl-case, but instead of expanding to cond+eq it
|
|
|
|
|
would be its own special form and would be compiled specially.
|
|
|
|
|
|
2015-08-26 21:05:43 +00:00
|
|
|
|
Then change pcase to use 'case' when applicable.
|
2014-09-26 22:19:12 +00:00
|
|
|
|
|
|
|
|
|
Then change the byte-compiler to recognize (cond ((eq x 'foo) bar) ...)
|
2015-08-26 21:05:43 +00:00
|
|
|
|
and turn it into a 'case' for more efficient execution.
|
2014-09-26 22:19:12 +00:00
|
|
|
|
|
|
|
|
|
** Improve the byte-compiler to recognize immutable (lexical) bindings
|
|
|
|
|
and get rid of them if they're used only once and/or they're bound to
|
|
|
|
|
a constant expression.
|
|
|
|
|
|
|
|
|
|
Such things aren't present in hand-written code, but macro expansion and
|
|
|
|
|
defsubst can often end up generating things like
|
|
|
|
|
(funcall (lambda (arg) (body)) actual) which then get optimized to
|
|
|
|
|
(let ((arg actual)) (body)) but should additionally get optimized further
|
2015-08-26 21:05:43 +00:00
|
|
|
|
when 'actual' is a constant/copyable expression.
|
2014-09-26 22:19:12 +00:00
|
|
|
|
|
|
|
|
|
** Add an "indirect goto" byte-code and use it for local lambda expressions.
|
|
|
|
|
E.g. when you have code like
|
|
|
|
|
|
|
|
|
|
(let ((foo (lambda (x) bar)))
|
|
|
|
|
(dosomething
|
|
|
|
|
(funcall foo toto)
|
|
|
|
|
(blabla (funcall foo titi))))
|
|
|
|
|
|
2015-08-26 21:05:43 +00:00
|
|
|
|
turn those 'funcalls' into jumps and their return into indirect jumps back.
|
2014-09-26 22:19:12 +00:00
|
|
|
|
|
|
|
|
|
** Compile efficiently local recursive functions
|
|
|
|
|
|
|
|
|
|
Similar to the previous point, we should be able to handle something like
|
|
|
|
|
|
|
|
|
|
(letrec ((loop () (blabla) (if (toto) (loop))))
|
|
|
|
|
(loop))
|
|
|
|
|
|
|
|
|
|
which ideally should generate the same byte-code as
|
|
|
|
|
|
|
|
|
|
(while (progn (blabla) (toto)))
|
|
|
|
|
|
|
|
|
|
* Things that were planned for Emacs-24
|
2010-03-07 20:08:38 +00:00
|
|
|
|
|
|
|
|
|
** concurrency: including it as an "experimental" compile-time option
|
2014-09-26 22:19:12 +00:00
|
|
|
|
sounds good. Of course there might still be big questions around "which form
|
|
|
|
|
of concurrency" we'll want.
|
2010-03-07 20:08:38 +00:00
|
|
|
|
** better support for dynamic embedded graphics: I like this idea (my
|
2012-08-04 18:07:50 +00:00
|
|
|
|
mpc.el code could use it for the volume widget), though I wonder if the
|
2010-03-07 20:08:38 +00:00
|
|
|
|
resulting efficiency will be sufficient.
|
|
|
|
|
** Spread Semantic.
|
|
|
|
|
** Improve the "code snippets" support: consolidate skeleton.el, tempo.el,
|
|
|
|
|
and expand.el (any other?) and then advertise/use/improve it.
|
|
|
|
|
** Improve VC: yes, there's a lot of work to be done there :-(
|
|
|
|
|
|
|
|
|
|
** Random things that cross my mind right now that I'd like to see (some of
|
|
|
|
|
them from my local hacks), but it's not obvious at all whether they'll
|
|
|
|
|
make it.
|
2010-05-19 02:56:44 +00:00
|
|
|
|
*** prog-mode could/should provide a better fill-paragraph default
|
|
|
|
|
that uses syntax-tables to recognize string/comment boundaries.
|
2010-03-07 20:08:38 +00:00
|
|
|
|
*** provide more completion-at-point-functions. Make existing
|
|
|
|
|
in-buffer completion use completion-at-point.
|
|
|
|
|
*** "functional" function-key-map that would make it easy to add (and
|
|
|
|
|
remove) mappings like "FOO-mouse-4 -> FOO-scroll-down",
|
|
|
|
|
"FOO-tab -> ?\FOO-\t", "uppercase -> lowercase", "[fringe KEY...] ->
|
|
|
|
|
[KEY]", "H-FOO -> M-FOO", "C-x C-y FOO -> H-FOO", ...
|
|
|
|

|
* Things related to elpa.gnu.org.
|
|
|
|
|
|
|
|
|
|
** Move idlwave to elpa.gnu.org.
|
|
|
|
|
Need to sync up the Emacs and external versions.
|
|
|
|
|

2015-02-21 01:38:43 +00:00
|
|
|
|
** Move Org mode to elpa.gnu.org.

* Simple tasks. These don't require much Emacs knowledge, they are
|
2008-01-19 20:13:59 +00:00
|
|
|
|
suitable for anyone from beginners to experts.
|
|
|
|
|
|
2008-08-06 03:46:11 +00:00
|
|
|
|
** Convert modes that use view-mode to be derived from special-mode instead.
|
|
|
|
|
|
2014-07-15 16:11:33 +00:00
|
|
|
|
** Major modes should have a menu entry.
|
2008-01-19 20:13:59 +00:00
|
|
|
|
|
2008-04-04 22:29:55 +00:00
|
|
|
|
** Check if all items on the mode-line have a suitable tooltip for all modes.
|
2008-01-19 20:13:59 +00:00
|
|
|
|
|
2008-03-08 20:21:40 +00:00
|
|
|
|
** edebug and debugger-mode should have a toolbar.
|
|
|
|
|
It can use the same icons as gud.
|
|
|
|
|
|
2008-01-19 20:13:59 +00:00
|
|
|
|
** Check what minor modes don't use define-minor-mode and convert them
|
|
|
|
|
to use it.
|
|
|
|
|
|
2015-08-26 21:05:43 +00:00
|
|
|
|
** Convert all defvars with leading '*' in the doc-strings into defcustoms
|
2008-04-03 04:12:51 +00:00
|
|
|
|
of appropriate :type and :group.
|
|
|
|
|
|
2015-08-26 21:05:43 +00:00
|
|
|
|
** Remove any leading '*'s from defcustom doc-strings.
|
2013-08-07 12:44:16 +00:00
|
|
|
|
[done?] [A lot of them are in CC Mode.]
|
2009-03-12 06:27:21 +00:00
|
|
|
|
|
|
|
|
|
** Remove unnecessary autoload cookies from defcustoms.
|
|
|
|
|
This needs a bit of care, since often people have become used to
|
|
|
|
|
expecting such variables to always be defined, eg when they modify
|
|
|
|
|
things in their .emacs.
|
|
|
|
|
|
2009-09-11 06:51:58 +00:00
|
|
|
|
** See if other files can use generated-autoload-file (see eg ps-print).
|
|
|
|
|
|
2012-01-18 03:38:59 +00:00
|
|
|
|
** Write more tests. Pick a fixed bug from the database, write a test
|
|
|
|
|
case to make sure it stays fixed. Or pick your favorite programming
|
|
|
|
|
major-mode, and write a test for its indentation. Or a version
|
|
|
|
|
control backend, and write a test for its status parser. Etc.
|
|
|
|
|
See test/automated for examples.

* Small but important fixes needed in existing features:

|
|
|
|
|
2008-03-23 17:13:42 +00:00
|
|
|
|
** Flymake's customization mechanism needs to be both simpler (fewer
|
|
|
|
|
levels of indirection) and better documented, so it is easier to
|
|
|
|
|
understand. I find it quite hard to figure out what compilation
|
|
|
|
|
command it will use.
|
|
|
|
|
|
|
|
|
|
I suggest totally rewriting that part of Flymake, using the simplest
|
2011-12-31 01:27:15 +00:00
|
|
|
|
mechanism that suffices for the specific needs. That will be easy
|
2008-03-23 17:13:42 +00:00
|
|
|
|
for users to customize.
|

** Distribute a bar cursor of width > 1 evenly between the two glyphs

** Fix the kill/yank treatment of invisible text. At the moment,
|
2003-09-02 17:43:01 +00:00
|
|
|
|
invisible text is placed in the kill-ring, so that the contents of
|
2005-06-20 14:01:37 +00:00
|
|
|
|
the ring may not correspond to the text as displayed to the user.
|
|
|
|
|
It ought to be possible to omit text which is invisible (due to a
|
2003-09-02 17:43:01 +00:00
|
|
|
|
text-property, overlay, or selective display) from the kill-ring.

25 years ago I hoped we would extend Emacs to do WYSIWYG word
|
2013-11-17 19:34:36 +00:00
|
|
|
|
processing. That is why we added text properties and variable
|
|
|
|
|
width fonts. However, more features are still needed to achieve this.

** Extend text-properties and overlays
|
2010-05-24 20:48:46 +00:00
|
|
|
|
*** Several text-property planes
|
|
|
|
|
This would get us rid of font-lock-face property (and I'd be happy to
|
|
|
|
|
get rid of char-property-alias-alist as well) since font-lock would
|
2015-08-26 21:05:43 +00:00
|
|
|
|
simply use the 'face' property in the 'font-lock' plane.
|
2014-09-26 22:19:12 +00:00
|
|
|
|
|
2015-08-26 21:05:43 +00:00
|
|
|
|
Basically 'put-text-property' and friends would take an extra argument PLANE
|
2014-09-26 22:19:12 +00:00
|
|
|
|
(maybe the best backward-compatible way to do that is to make it so that
|
|
|
|
|
PROPERTY can be a cons cell (PLANE . PROP)). So font-lock would
|
|
|
|
|
do (put-text-property start end '(font-lock . face) value).
|
|
|
|
|
|
|
|
|
|
All the properties coming from the various planes would get merged via an Elisp
|
2015-08-26 21:05:43 +00:00
|
|
|
|
function (so it can merge 'face' differently than 'keymap' or it could give
|
2014-09-26 22:19:12 +00:00
|
|
|
|
different priorities to different planes (we could imagine enabling/disabling
|
|
|
|
|
planes)). The merging would not happen lazily while looking up properties but
|
2015-08-26 21:05:43 +00:00
|
|
|
|
instead it would take place eagerly in 'add-text-properties'. This is based on
|
2014-09-26 22:19:12 +00:00
|
|
|
|
the idea that it's much more frequent to lookup properties than to
|
|
|
|
|
modify them. Also, when properties are looked up during redisplay, we
|
|
|
|
|
generally can't run Elisp code, whereas we generally can do that when
|
|
|
|
|
properties are added.

*** Move overlays to intervals.c
|
|
|
|
|
|
|
|
|
|
Currently overlays are implemented as (two) sorted singly linked lists (one
|
|
|
|
|
for overlays_before some position and one for overlay_after that
|
|
|
|
|
position, for some quirky definition of "before" and "after").
|
2015-08-26 21:05:43 +00:00
|
|
|
|
The function 'overlay-recenter' changes the position used for the split
|
2014-09-26 22:19:12 +00:00
|
|
|
|
(and is called internally in various situations).
|
|
|
|
|
|
|
|
|
|
Each overlay is itself implemented with two markers (which keep track of
|
|
|
|
|
the overlay-start and overlay-end). Markers are implemented as
|
|
|
|
|
a non-sorted singly linked list of markers. So every text
|
|
|
|
|
insertion/deletion requires O(N) time, where N is the number of markers
|
|
|
|
|
since we have to go down that list to update those markers that are
|
|
|
|
|
affected by the modification.
|
|
|
|
|
|
|
|
|
|
You can start in src/buffer.[ch], maybe grepping for overlays_before for
|
|
|
|
|
a starting point.
|
|
|
|
|
|
|
|
|
|
Text-properties, OTOH, are implemented with a (mostly) balanced binary
|
|
|
|
|
tree. This is implemented in src/intervals.[ch].
|
|
|
|
|
|
|
|
|
|
So we'd like to change overlays so that they don't use markers (and we
|
|
|
|
|
don't keep them in two sorted singly-linked lists) any more. Instead,
|
|
|
|
|
we'll store them inside the balanced binary tree used for
|
|
|
|
|
text-properties. I think we can use the "augmented tree" approach
|
|
|
|
|
described in https://en.wikipedia.org/wiki/Interval_tree.
|
|
|
|
|
|
|
|
|
|
To ease up debugging during development, I'd guess the implementation
|
|
|
|
|
would first add the new stuff, keeping the old stuff (i.e. add to
|
|
|
|
|
Lisp_Overlay whichever fields are needed for the new code, while keeping
|
|
|
|
|
the old ones, add needed overlay fields to the intervals tree, but keep
|
|
|
|
|
the old fields, the overlays_before etc...). This way, you can add
|
|
|
|
|
consistency checks that make sure the new code computes the same results
|
|
|
|
|
as the old code. And once that works well, we can remove the old code
|
|
|
|
|
and old fields.

** Having tabs above a window to switch buffers in it.
|
|
|
|
|
|
|
|
|
|
** "Perspectives" are named persistent window configurations. We have
|
|
|
|
|
had the window configuration mechanism in GNU Emacs since the
|
|
|
|
|
beginning but we have never developed a good user interface to take
|
|
|
|
|
advantage of them. Eclipse's user interface seems to be good.
|
|
|
|
|
|
|
|
|
|
Perspectives work well even if you do the equivalent of C-x 4 C-f
|
|
|
|
|
because of the distinction between view windows vs file windows. In
|
|
|
|
|
Emacs this is more or less the "dedicated window" feature, but we have
|
|
|
|
|
never really made it work for this.
|
|
|
|
|
|
|
|
|
|
Perspectives also need to interact with the tabs.

** FFI (foreign function interface)

|
|
|
|
|
2014-07-04 07:35:22 +00:00
|
|
|
|
One way of doing this is to start with fx's dynamic loading, and use it
|
|
|
|
|
to implement things like auto-loaded buffer parsers and database
|
|
|
|
|
access in cases which need more than Lisp.

|
|
** Compilation error navigation bar, parallel to the scroll bar,
|
|
|
|
|
indicating where in the buffer there are compilation errors.
|
|
|
|
|
Perhaps we could arrange to display these error indications on top
|
|
|
|
|
of the scroll bar itself. That depends on to what extent toolkit
|
|
|
|
|
scroll bars are extensible.

** Make the Lucid menu widget display multilingual text. [This
|
2003-02-04 18:36:25 +00:00

|

in the menu or by rendering in an unmapped window and copying the

2005-03-18 21:07:27 +00:00

|
pixels. The current code assumes a specific locale; that isn't good

|
enough even if X can render the arbitrary text] [The gtk
|
2003-06-23 18:36:25 +00:00

2005-03-18 21:07:27 +00:00

Maybe making Lucid menus work like Gtk's (i.e. just force utf-8) is good

when the user tries to use the menubar.

This requires the RIT to forward the WM_INITMENU message to

|
*** Missing features
|
|
|
|
|
|
|
|
|
|
This sections contains features found in other official Emacs ports.
|
|
|
|
|
|
2016-02-28 09:26:52 +00:00
|
|

|
**** Support for xwidgets
|
2016-02-27 19:05:10 +00:00
|
|
|
|
|
2016-02-28 09:26:52 +00:00
|
|
|
|
Emacs 25 has support for xwidgets, a system to include operating
|
2016-02-27 19:05:10 +00:00
|
|
|
|
system components into an Emacs buffer. The components range from
|
2016-02-28 09:26:52 +00:00
|
|
|
|
simple buttons to webkit (effectively, a web browser).
|
2016-02-27 19:05:10 +00:00
|
|
|
|
|
2016-02-28 09:26:52 +00:00
|
|
|
|
Currently, xwidgets works only for the gtk+ framework but it is
|
2016-02-27 19:05:10 +00:00
|
|
|
|
designed to be compatible with multiple Emacs ports.
|
|
|
|
|
|
2016-02-28 09:26:52 +00:00
|
|
|
|
**** Respect 'frame-inhibit-implied-resize'
|
2016-02-27 19:05:10 +00:00
|
|
|
|
|
2016-02-28 09:26:52 +00:00
|
|
|
|
When the variable 'frame-inhibit-implied-resize' is non-nil, frames
|
2016-02-27 19:05:10 +00:00
|
|
|
|
should not be resized when operations like changing font or toggling
|
|
|
|
|
the tool bar is performed.
|
|
|
|
|
|
|
|
|
|
Unfortunately, the tool bar (and possible other operations) always
|
|
|
|
|
resize the frame.
|
|
|
|
|
|
2016-02-28 09:26:52 +00:00
|
|
|
|
**** Support 'proced' (implement 'process-attributes')
|
2016-02-27 19:05:10 +00:00
|
|
|
|
|
|
|
|
|
Unfortunately, a user-level process like Emacs does not have the
|
2016-11-06 07:33:43 +00:00
|
|
|
|
privileges to get information about other processes under macOS.
|
2016-02-27 19:05:10 +00:00
|
|
|
|
|
|
|
|
|
There are other ways to do this:
|
|
|
|
|
|
|
|
|
|
1) Spawn "ps" and parse the output ("ps" has superuser privileges).
|
|
|
|
|
|
|
|
|
|
2) Sign Emacs as part of the distribution process.
|
|
|
|
|
|
|
|
|
|
3) Ask the user to self-sign Emacs, if this feature is of interest.
|

|
|
Anders Lindgren <andlind@gmail.com> has implemented
|
2016-11-06 07:33:43 +00:00
|
|
|
|
'process-attributes' for macOS, which currently only work when
|
2016-02-27 19:05:10 +00:00
|
|
|
|
running Emacs as root.
|
|
|
|

|
|
|
|
|
See this article by Bozhidar Batsov for an overview of Proced:

|
|
|
|
|
|
**** Tooltip properties
|
|
|
|
|
|
|
|
|
|
Tooltip properties like the background color and font are hard-wired,
|
|
|
|
|
even though Emacs allows a user to customize such features.
|
|
|
|
|
|
|
|
|
|
*** New features
|
|
|
|
|
|
2016-11-06 07:33:43 +00:00
|
|
|
|
This section contains features unique to Nextstep and/or macOS.
|
2016-02-27 19:05:10 +00:00
|
|
|
|
|
|
|
|
|
**** PressAndHold for writing accented character
|
|
|
|
|
|
2016-11-06 07:33:43 +00:00
|
|
|
|
On macOS, many application support the press and hold pattern to
|
2016-02-27 19:05:10 +00:00
|
|
|
|
invoke a menu of accented characters. (See example at
|
|
|
|
|
https://support.apple.com/en-us/HT201586 .)
|
|
|
|
|
|
|
|
|
|
Currently, this doesn't work in Emacs.
|
|
|
|
|
|
|
|
|
|
Note that "ns-win.el" explicitly disables this.
|
|
|
|
|
|
|
|
|
|
Note: This feature might not be allowed to be implemented until also
|
|
|
|
|
implemented in Emacs for a free system.
|
|
|
|
|
|
|
|
|
|
**** Floating scroll bars
|
|
|
|
|
|
2016-11-06 07:33:43 +00:00
|
|
|
|
In modern macOS applications, the scroll bar often floats over the
|
2016-02-27 19:05:10 +00:00
|
|
|
|
content, and is invisible unless actually used. This makes the user
|
|
|
|
|
interface less cluttered and more area could be used to contain text.
|
|
|
|
|
|
|
|
|
|
With floating scroll bars, the user interface would look like it does
|
|
|
|
|
when they are disabled today. However, they will be made visible when
|
|
|
|
|
a scroll action is initiated, e.g. by putting two fingers on a
|
|
|
|
|
trackpad.
|
|
|
|
|
|
|
|
|
|
Note: This feature might not be allowed to be implemented until also
|
|
|
|
|
implemented in Emacs for a free system.
|
|
|
|
|
|
|
|
|
|
*** Features from the "mac" port
|
|
|
|
|
|
|
|
|
|
This section contains features available in the "mac" Emacs port.
|
|
|
|
|
|
|
|
|
|
As the "mac" port (as of this writing) isn't an official Emacs port,
|
|
|
|
|
it might contain features not following the FSF rule "must exist on
|
|
|
|
|
free systems".
|
|
|
|
|
|
|
|
|
|
The "mac" port is based on the Emacs 22 C-based Carbon interface.
|
|
|
|
|
It has been maintained in parallel to the official Cocoa-based NS
|
|
|
|
|
interface. The Carbon interface has been enhanced, and a number of the
|
|
|
|
|
features of that interface could be implemented NS.
|
|
|
|
|
|
|
|
|
|
**** Smooth scrolling -- maybe not a good idea
|
|
|
|
|
|
|
|
|
|
Today, by default, scrolling with a trackpad makes the text move in
|
|
|
|
|
steps of five lines. (Scrolling with SHIFT scrolls one line at a time.)
|
|
|
|
|
|
|
|
|
|
The "mac" port provides smooth, pixel-based, scrolling. This is a very
|
|
|
|
|
popular features. However, there are drawbacks to this method: what
|
|
|
|
|
happens if only a fraction of a line is visible at the top of a
|
|
|
|
|
window, is the partially visible text considered part of the window or
|
2016-02-28 09:26:52 +00:00
|
|
|
|
not? (Technically, what should 'window-start' return.)
|
2016-02-27 19:05:10 +00:00
|
|
|
|
|
|
|
|
|
An alternative would be to make one-line scrolling the default on NS
|
|
|
|
|
(or in Emacs in general).
|
|
|
|
|
|
|
|
|
|
Note: This feature might not be allowed to be implemented until also
|
|
|
|
|
implemented in Emacs for a free system.
|
|
|
|
|
|
|
|
|
|
**** Mouse gestures
|
|
|
|
|
|
2016-02-28 09:26:52 +00:00
|
|
|
|
The "mac" port defines the gestures 'swipe-left/right/up/down',
|
|
|
|
|
'magnify-up/down', and 'rotate-left/right'.
|
2016-02-27 19:05:10 +00:00
|
|
|
|
|
|
|
|
|
It also binds the magnification commands to change the font
|
|
|
|
|
size. (This should be not be done in a specific interface, instead
|
|
|
|
|
Emacs should do this binding globally.)
|
|
|
|
|
|
|
|
|
|
Note: This feature might not be allowed to be implemented until also
|
|
|
|
|
implemented in Emacs for a free system.
|
|
|
|
|
|
|
|
|
|
**** Synthesize bold fonts
|
|
|
|
|
|
|
|
|
|
*** Open issues
|
|
|
|
|
|
|
|
|
|
This section contains issues where there is an ongoing debate.
|
|
|
|
|
|
|
|
|
|
**** Key bindings of CMD and ALT
|
|
|
|
|
|
|
|
|
|
Currently in the "ns" port, ALT is bound to Meta and CMD is bound to
|
2016-11-06 07:33:43 +00:00
|
|
|
|
Super -- allowing the user to use typical macOS commands like CMD-A to
|
2016-02-27 19:05:10 +00:00
|
|
|
|
mark everything.
|
|
|
|
|
|
|
|
|
|
Unfortunately, when using an international keyboard, you can't type
|
|
|
|
|
normal characters like "(" etc.
|
|
|
|
|
|
|
|
|
|
There are many alternative key bindings. One solution is to bind CMD
|
|
|
|
|
to Meta and pass ALT to the system. In fact, this is what Emacs did up
|
|
|
|
|
to, and including, version 22. Also, this is how the "mac" port binds
|
|
|
|
|
the keys.
|
|
|
|
|
|
|
|
|
|
One could envision asymmetrical variants as well, however, this is
|
|
|
|
|
inappropriate for the default setting.

*** Internal development features
|
|
|
|
|
|
|
|
|
|
**** Regression test system (or at least a checklist)
|
|
|
|
|
|
|
|
|
|
Today, after each change to the user interface, Emacs must be manually
|
|
|
|
|
tested. Often, small details are overlooked ("Oh, I didn't test
|
|
|
|
|
toggling the tool-bar in one of the full screen modes, when multiple
|
|
|
|
|
frame were open -- silly me.")
|
|
|
|
|
|
|
|
|
|
It would be an enormous help if this could be tested automatically.
|
|
|
|
|
Many features are generic, however, the NS interface provides a number
|
|
|
|
|
of unique features.
|
|
|
|
|
|
|
|
|
|
**** Existing packages
|
|
|
|
|
|
|
|
|
|
Note that there is a generic UI test named frame-test.el, see
|
|
|
|
|
http://debbugs.gnu.org/21415#284 .
|
|
|
|
|
The NS interface passes this, with the exception of two toolbar-related errors.
|
|
|
|
|
|
|
|
|
|
**** Anders frame test
|
|
|
|
|
|
|
|
|
|
Anders Lindgren <andlind@gmail.com> has implemented some (very basic)
|
|
|
|
|
tests for full screen, toolbar, and auto-hiding the menu bar.
|
|
|
|
|
|
|
|
|
|
**** Make sure all build variants work
|
|
|
|
|
|
|
|
|
|
Emacs can be build in a number of different ways. For each feature,
|
|
|
|
|
consider if is really is "NS" specific, or if it should be applied to
|
|
|
|
|
all build versions.
|
|
|
|
|
|
2016-11-06 07:33:43 +00:00
|
|
|
|
- With the "NS" interface. This is the normal way to build Emacs on
|
|
|
|
|
macOS.
|
2016-02-27 19:05:10 +00:00
|
|
|
|
|
2016-11-06 07:33:43 +00:00
|
|
|
|
- With the "X11" interface. On macOS, this is mainly of interest to
|
2016-02-27 19:05:10 +00:00
|
|
|
|
developers of Emacs to get a "reference" interface implementations.
|
|
|
|
|
However, it might be of interest for people working remotely, as X11
|
|
|
|
|
applications can be used over a network connection.
|
|
|
|
|
|
|
|
|
|
- Console only.

**** Incorrect translation of Super modifier with Ctrl or Meta on macOS

2016-02-27 19:05:10 +00:00
|
|
|
|
|
2016-02-28 09:26:52 +00:00
|
|
|
|
When pressing 'M-s-a', Emacs replies "M-s-å is undefined". What
|
2016-02-27 19:05:10 +00:00
|
|
|
|
happened is a mix of Emacs view that Meta and Super has been pressed,
|
2016-11-06 07:33:43 +00:00
|
|
|
|
and macOS view that ALT-a should yield "å" (U+00E5 LATIN SMALL LETTER
|
|
|
|
|
A WITH RING ABOVE).
|
2016-02-27 19:05:10 +00:00
|
|
|
|

2016-02-28 09:26:52 +00:00
|
|

The bug reports suggest two different patches; unfortunately, neither
|
|
|
|
|
works properly. For example:
|
2016-02-27 19:05:10 +00:00

|
|
|
|
Use a Swedish keyboard layout

**** Toggling the toolbar in fullheight or maximized modes
|
|
|
|
|
|
|
|
|
|
The toolbar, in the NS interface, is not considered part of the text
|
|
|
|
|
area. When it is toggled, the Emacs frame change height accordingly.
|
|
|
|
|
|
|
|
|
|
Unfortunately, this also occurs when the frame is in fullheight or
|
|
|
|
|
maximized modes (N.B. this is not the same as "fullscreen"). The
|
|
|
|
|
effect is that the full frame size either increases (stretching down
|
|
|
|
|
below the lower edge of the screen) or decreases (leaving space
|
|
|
|
|
between the lower edge of the frame and the lower edge of the screen).
|
|
|
|
|
|
|
|
|
|
A better solution would be for the frame to retain its size,
|
|
|
|
|
i.e. change the text area.

**** The event loop does not redraw.
|
2016-02-27 19:05:10 +00:00
|
|
|
|
A problem is that redraw don't happen during resize,
|
|
|
|
|
because we can't break out from the NSapp loop during resize.
|
|
|
|
|
There was a special trick to detect mouse press in the lower right
|
|
|
|
|
corner and track mouse movements, but this did not work well, and was
|
|
|
|
|
not scalable to the new Lion "resize on every window edge" behavior.
|
|
|
|
|
[As of trunk r109635, 2012-08-15, the event loop no longer polls.]

*** Support reordering structured text
|
|
|
|
|
Two important use cases: (1) comments and strings in program sources,
|
|
|
|
|
and (2) text with markup, like HTML or XML.
|
|
|
|
|
|
|
|
|
|
One idea is to invent a special text property that would instruct the
|
|
|
|
|
display engine to reorder only the parts of buffer text covered by
|
|
|
|
|
that property. The display engine will then push its state onto the
|
|
|
|
|
iterator stack, restrict the bidi iterator to accessing only the
|
|
|
|
|
portion of buffer text covered by the property, reorder the text, then
|
|
|
|
|
pop its state from stack and continue as usual. This will require
|
|
|
|
|
minor changes in the bidi_it structure.
|
|
|
|
|
|
|
|
|
|
This design requires Lisp-level code to put the text properties on the
|
|
|
|
|
relevant parts of the buffer text. That could be done using JIT
|
|
|
|
|
fontifications, or as a preliminary processing when the file is
|
|
|
|
|
visited. With HTML/XML, the code that puts text properties needs to
|
|
|
|
|
pay attention to the bidi directives embedded in the HTML/XML stream.

*** Allow the user to control the direction of the UI
|
|
|
|
|
|
|
|
|
|
**** Introduce user option to control direction of mode line.
|
2012-04-07 14:57:25 +00:00
|
|
|
|
One problem is the header line, which is produced by the same routines
|
|
|
|
|
as the mode line. While it makes sense to have the mode-line
|
2011-06-18 13:28:53 +00:00
|
|
|
|
direction controlled by a single global variable, header lines are
|
|
|
|
|
buffer-specific, so they need a separate treatment in this regard.
|
|
|
|
|
|
|
|
|
|
**** User options to control direction of menu bar and tool bar.
|
|
|
|
|
For the tool bar, it's relatively easy: set it.paragraph_embedding
|
|
|
|
|
in redisplay_tool_bar according to the user variable, and make
|
|
|
|
|
f->desired_tool_bar_string multibyte with STRING_SET_MULTIBYTE. Some
|
|
|
|
|
minor changes will be needed to set the right_box_line_p and
|
|
|
|
|
left_box_line_p flags correctly for the R2L tool bar.
|
|
|
|
|
|
|
|
|
|
However, it makes no sense to display the tool bar right to left if
|
|
|
|
|
the menu bar cannot be displayed in the same direction.
|
|
|
|
|
|
|
|
|
|
R2L menu bar is tricky for the same reasons as the mode line. In
|
|
|
|
|
addition, toolkit builds create their menu bars in toolkit-specific
|
|
|
|
|
parts of code, bypassing xdisp.c, so those parts need to be enhanced
|
|
|
|
|
with toolkit-specific code to display the menu bar right to left.

** ImageMagick support

|
|
|
|
|
|
|
|

*** image-type-header-regexps priorities the jpeg loader over the

|
2011-12-04 08:02:42 +00:00
|
|
|
|
preferring the ImageMagick loader? The user might like zooming etc in jpegs.
|
2010-09-09 02:30:31 +00:00
|
|
|
|
|
|
|
|
|
Try (setq image-type-header-regexps nil) for a quick hack to prefer
|
|
|
|
|
ImageMagick over the jpg loader.

*** For some reason it's unbearably slow to look at a page in a large
|
2010-09-09 02:30:31 +00:00
|
|
|
|
image bundle using the :index feature. The ImageMagick "display"
|
|
|
|
|
command is also a bit slow, but nowhere near as slow as the Emacs
|
|
|
|
|
code. It seems ImageMagick tries to unpack every page when loading the
|
|
|
|
|
bundle. This feature is not the primary usecase in Emacs though.
|
|
|
|
|
|
|
|
|
|
ImageMagick 6.6.2-9 introduced a bugfix for single page djvu load. It
|
|
|
|
|
is now much faster to use the :index feature, but still not very fast.
|
|
|
|
|
|
|
|
|
|
*** Try to cache the num pages calculation. It can take a while to
|
|
|
|
|
calculate the number of pages, and if you need to do it for each page

view, page-flipping becomes uselessly slow.

2010-09-09 02:30:31 +00:00
|

|
*** Integrate with image-mode.
|
|
|
|
|
Some work has been done, e.g. M-x image-transform-fit-to-height will
|
|
|
|
|
fit the image to the height of the Emacs window.
|
|
|
|
|
|
|
|
|
|
*** Look for optimizations for handling images with low depth.
|
|
|
|
|
Currently the code seems to default to 24 bit RGB which is costly for
|
|
|
|
|
images with lower bit depth.
|
|
|
|
|
|
|
|
|
|
*** Decide what to do with some uncommitted imagemagick support
|
|
|
|
|
functions for image size etc.

prefix of any other name, should C-return complete on attribute names?
|
|
|
|
|
|
|
|
|
|
**** When completing attributes, more consistent to ignore all attributes
|
|
|
|
|
after point.
|
|
|
|
|
|
|
|
|
|
**** Inserting attribute value completions needs to be sensitive to what
|
|
|
|
|
delimiter is used so that it quotes the correct character.
|
|
|
|
|
|
|
|
|
|
**** Complete on encoding-names in XML decl.
|
|
|
|
|
|
|
|
|
|
**** Complete namespace declarations by searching for all namespaces
|
|
|
|
|
mentioned in the schema.
|
|
|
|
|
|
|
|
|
|
*** Well-formed XML support
|
|
|
|
|
|
|
|
|
|
**** Deal better with Mule-UCS
|
|
|
|
|
|
|
|
|
|
**** Deal with UTF-8 BOM when reading.
|
|
|
|
|
|
|
|
|
|
**** Complete entity names.
|
|
|
|
|
|
|
|
|
|
**** Provide some support for entity names for MathML.
|
|
|
|
|
|
|
|
|
|
**** Command to repeat the last tag.
|
|
|
|
|
|
|
|
|
|
**** Support for changing between character references and characters.
|
|
|
|
|
Need to check that context is one in which character references are
|
|
|
|
|
allowed. xmltok prolog parsing will need to distinguish parameter
|
|
|
|
|
literals from other kinds of literal.
|
|
|
|
|
|
|
|
|
|
**** Provide a comment command to bind to M-; that works better than the
|
|
|
|
|
normal one.
|
|
|
|
|
|
|
|
|
|
**** Make indenting in a multi-line comment work.
|
|
|
|
|
|
|
|
|
|
**** Structure view. Separate buffer displaying element tree.
|
|
|
|
|
Be able to navigate from structure view to document and vice-versa.
|
|
|
|
|
|
|
|
|
|
**** Flash matching >.
|
|
|
|
|
|
|
|
|
|
**** Smart selection command that selects increasingly large syntactically
|
|
|
|
|
coherent chunks of XML. If point is in an attribute value, first
|
|
|
|
|
select complete value; then if command is repeated, select value plus
|
|
|
|
|
delimiters, then select attribute name as well, then complete
|
|
|
|
|
start-tag, then complete element, then enclosing element, etc.
|
|
|
|
|
|
|
|
|
|
**** ispell integration.
|
|
|
|
|
|
|
|
|
|
**** Block-level items in mixed content should be indented, e.g:
|
|
|
|
|
<para>This is list:
|
|
|
|
|
<ul>
|
|
|
|
|
<li>item</li>
|
|
|
|
|
|
|
|
|
|
**** Provide option to indent like this:
|
|
|
|
|
<para>This is a paragraph
|
|
|
|
|
occupying multiple lines.</para>
|
|
|
|
|
|
|
|
|
|
**** Option to add make a / that closes a start-tag electrically insert a
|
|
|
|
|
space for the XHTML guys.
|
|
|
|
|
|
|
|
|
|
**** C-M-q should work.
|
|
|
|
|
|
|
|
|
|
*** Datatypes
|
|
|
|
|
|
|
|
|
|
**** Figure out workaround for CJK characters with regexps.
|
|
|
|
|
|
|
|
|
|
**** Does category C contain Cn?
|
|
|
|
|
|
|
|
|
|
**** Do ENTITY datatype properly.
|
|
|
|
|
|
|
|
|
|
*** XML Parsing Library
|
|
|
|
|
|
|
|
|
|
**** Parameter entity parsing option, nil (never), t (always),
|
|
|
|
|
unless-standalone (unless standalone="yes" in XML declaration).
|
|
|
|
|
|
|
|
|
|
**** When a file is currently being edited, there should be an option to
|
|
|
|
|
use its buffer instead of the on-disk copy.
|
|
|
|
|
|
|
|
|
|
*** Handling all XML features
|
|
|
|
|
|
|
|
|
|
**** Provide better support for editing external general parsed entities.
|
|
|
|
|
Perhaps provide a way to force ignoring undefined entities; maybe turn
|
|
|
|
|
this on automatically with <?xml encoding=""?> (with no version
|
|
|
|
|
pseudo-att).
|
|
|
|
|
|
|
|
|
|
**** Handle internal general entity declarations containing elements.
|
|
|
|
|
|
|
|
|
|
**** Handle external general entity declarations.
|
|
|
|
|
|
|
|
|
|
**** Handle default attribute declarations in internal subset.
|
|
|
|
|
|
|
|
|
|
**** Handle parameter entities (including DTD).
|
|
|
|
|
|
|
|
|
|
*** RELAX NG
|
|
|
|
|
|
|
|
|
|
**** Do complete schema checking, at least optionally.
|
|
|
|
|
|
|
|
|
|
**** Detect include/external loops during schema parse.
|
|
|
|
|
|
|
|
|
|
**** Coding system detection for schemas. Should use utf-8/utf-16 per the
|
|
|
|
|
spec. But also need to allow encodings other than UTF-8/16 to support
|
|
|
|
|
CJK charsets that Emacs cannot represent in Unicode.
|
|
|
|
|
|
|
|
|
|
*** Catching XML errors
|
|
|
|
|
|
|
|
|
|
**** Check public identifiers.
|
|
|
|
|
|
|
|
|
|
**** Check default attribute values.
|
|
|
|
|
|
|
|
|
|
*** Performance
|
|
|
|
|
|
|
|
|
|
**** Explore whether overlay-recenter can cure overlays performance problems.
|
|
|
|
|
|
|
|
|
|
**** Cache schemas. Need to have list of files and mtimes.
|
|
|
|
|
|
|
|
|
|
**** Make it possible to reduce rng-validate-chunk-size significantly,
|
|
|
|
|
perhaps to 500 bytes, without bad performance impact: don't do
|
|
|
|
|
redisplay on every chunk; pass continue functions on other uses of
|
|
|
|
|
rng-do-some-validation.
|
|
|
|
|
|
|
|
|
|
**** Cache after first tag.
|
|
|
|
|
|
|
|
|
|
**** Introduce a new name class that is a choice between names (so that
|
|
|
|
|
we can use member)
|
|
|
|
|
|
|
|
|
|
**** intern-choice should simplify after patterns with same 1st/2nd args
|
|
|
|
|
|
|
|
|
|
**** Large numbers of overlays slow things down dramatically. Represent
|
|
|
|
|
errors using text properties. This implies we cannot incrementally
|
|
|
|
|
keep track of the number of errors, in order to determine validity.
|
|
|
|
|
Instead, when validation completes, scan for any characters with an
|
|
|
|
|
error text property; this seems to be fast enough even with large
|
|
|
|
|
buffers. Problem with error at end of buffer, where there's no
|
|
|
|
|
character; need special variable for this. Need to merge face from
|
|
|
|
|
font-lock with the error face: use :inherit attribute with list of two
|
|
|
|
|
faces. How do we avoid making rng-valid depend on nxml-mode?
|
|
|
|
|
|
|
|
|
|
*** Error recovery
|
|
|
|
|
|
|
|
|
|
**** Don't stop at newline in looking for close of start-tag.
|
|
|
|
|
|
|
|
|
|
**** Use indentation to guide recovery from mismatched end-tags
|
|
|
|
|
|
|
|
|
|
**** Don't keep parsing when currently not well-formed but previously
|
|
|
|
|
well-formed
|
|
|
|
|
|
|
|
|
|
**** Try to recover from a bad start-tag by popping an open element if
|
|
|
|
|
there was a mismatched end-tag unaccounted for.
|
|
|
|
|
|
|
|
|
|
**** Try to recover from a bad start-tag open on the hypothesis that there
|
|
|
|
|
was an error in the namespace URI.
|
|
|
|
|
|
|
|
|
|
**** Better recovery from ill-formed XML declarations.

*** Usability improvements
|
2010-09-09 02:34:25 +00:00
|
|
|
|
|
|
|
|
|
**** Should print a "Parsing..." message during long movements.
|
|
|
|
|
|
|
|
|
|
**** Provide better position for reference to undefined pattern error.
|
|
|
|
|
|
|
|
|
|
**** Put Well-formed in the mode-line when validating against any-content.
|
|
|
|
|
|
|
|
|
|
**** Trim marking of illegal data for leading and trailing whitespace.
|
|
|
|
|
|
|
|
|
|
**** Show Invalid status as soon as we are sure it's invalid, rather than
|
|
|
|
|
waiting for everything to be completely up to date.
|
|
|
|
|
|
|
|
|
|
**** When narrowed, Valid or Invalid status should probably consider only
|
|
|
|
|
validity of narrowed region.
|
|
|
|
|
|
|
|
|
|
*** Bug fixes
|
|
|
|
|
|
|
|
|
|
**** Need to give an error for a document like: <foo/><![CDATA[ ]]>
|
|
|
|
|
|
|
|
|
|
**** Make nxml-forward-balanced-item work better for the prolog.
|
|
|
|
|
|
|
|
|
|
**** Make filling and indenting comments work in the prolog.
|
|
|
|
|
|
|
|
|
|
**** Should delete RNC Input buffers.
|
|
|
|
|
|
|
|
|
|
**** Figure out what regex use for NCName and use it consistently,
|
|
|
|
|
|
|
|
|
|
**** Should have not-well-formed tokens in ref.
|
|
|
|
|
|
|
|
|
|
**** Require version in XML declaration? Probably not because prevents
|
|
|
|
|
use for external parsed entities. At least forbid standalone without version.
|
|
|
|
|
|
|
|
|
|
**** Reject schema that compiles to rng-not-allowed-ipattern.
|
|
|
|
|
|
|
|
|
|
**** Move point backwards on schema parse error so that it's on the right token.
|
|
|
|
|
|
|
|
|
|
*** Internal
|
|
|
|
|
|
|
|
|
|
**** Use rng-quote-string consistently.
|
|
|
|
|
|
|
|
|
|
**** Use parsing library for XML to texinfo conversion.
|
|
|
|
|
|
|
|
|
|
**** Rename xmltok.el to nxml-token.el. Use nxml-t- prefix instead of
|
|
|
|
|
xmltok-. Change nxml-t-type to nxml-t-token-type, nxml-t-start to
|
|
|
|
|
nxml-t-token-start.
|
|
|
|
|
|
|
|
|
|
**** Can we set fill-prefix to nil and rely on indenting?
|
|
|
|
|
|
|
|
|
|
**** xmltok should make available replacement text of entities containing
|
|
|
|
|
elements
|
|
|
|
|
|
|
|
|
|
**** In rng-valid, instead of using modification-hooks and
|
|
|
|
|
insert-behind-hooks on dependent overlays, use same technique as nxml-mode.
|
|
|
|
|
|
|
|
|
|
*** Fontification
|
|
|
|
|
|
|
|
|
|
**** Allow face to depend on element qname, attribute qname, attribute
|
|
|
|
|
value. Use list with pairs of (R . F), where R specifies regexps and
|
|
|
|
|
F specifies faces. How can this list be made to depend on the document type?
|
|
|
|
|
|
|
|
|
|
*** Other
|
|
|
|
|
|
|
|
|
|
**** Support RELAX NG XML syntax (use XML parsing library).
|
|
|
|
|
|
|
|
|
|
**** Support W3C XML Schema (use XML parsing library).
|
|
|
|
|
|
|
|
|
|
**** Command to infer schema from current document (like trang).
|
|
|
|
|
|
|
|
|
|
*** Schemas
|
|
|
|
|
|
|
|
|
|
**** XSLT schema should take advantage of RELAX NG to express cooccurrence
|
|
|
|
|
constraints on attributes (e.g. xsl:template).
|
|
|
|
|
|
|
|
|
|
*** Documentation
|
|
|
|
|
|
|
|
|
|
**** Move material from README to manual.
|
|
|
|
|
|
|
|
|
|
**** Document encodings.
|
|
|
|
|
|
|
|
|
|
*** Notes
|
|
|
|
|
|
|
|
|
|
**** How can we allow an error to be displayed on a different token from
|
|
|
|
|
where it is detected? In particular, for a missing closing ">" we
|
|
|
|
|
will need to display it at the beginning of the following token. At the
|
|
|
|
|
moment, when we parse the following token the error overlay will get cleared.
|
|
|
|
|
|
|
|
|
|
**** How should rng-goto-next-error deal with narrowing?
|
|
|
|
|
|
|
|
|
|
**** Perhaps should merge errors having same start position even if they
|
|
|
|
|
have different ends.
|
|
|
|
|
|
|
|
|
|
**** How to handle surrogates? One possibility is to be compatible with
|
|
|
|
|
utf8.e: represent as sequence of 4 chars. But utf-16 is incompatible
|
|
|
|
|
with this.
|
|
|
|
|
|
|
|
|
|
**** Should we distinguish well-formedness errors from invalidity errors?
|
|
|
|
|
(I think not: we may want to recover from a bad start-tag by implying
|
|
|
|
|
an end-tag.)
|
|
|
|
|
|
|
|
|
|
**** Seems to be a bug with Emacs, where a mouse movement that causes
|
|
|
|
|
help-echo text to appear counts as pending input but does not cause
|
|
|
|
|
idle timer to be restarted.
|
|
|
|
|
|
|
|
|
|
**** Use XML to represent this file.
|
|
|
|
|
|
|
|
|
|
**** I had a TODO which said simply "split-string". What did I mean?
|
|
|
|
|
|
|
|
|
|
**** Investigate performance on large files all on one line.
|
|
|
|
|
|
|
|
|
|
*** Issues for Emacs versions >= 22
|
|
|
|
|
|
|
|
|
|
**** Take advantage of UTF-8 CJK support.
|
|
|
|
|
|
|
|
|
|
**** Supply a next-error-function.
|
|
|
|
|
|
|
|
|
|
**** Investigate this NEWS item "Emacs now tries to set up buffer coding
|
|
|
|
|
systems for HTML/XML files automatically."
|
|
|
|
|
|
|
|
|
|
**** Take advantage of the pointer text property.
|
|
|
|
|
|
|
|
|
|
**** Leverage char-displayable-p.

|
** RefTeX
|
|
|
|
|
|
|
|
|
|
*** Provide a wdired-like mode for editing RefTeX TOC buffers.
|
|
|
|
|
As a first step, renaming of sections could be supported. Ultimately,
|
|
|
|
|
it would be great if it also supported moving sections, e.g., by
|
|
|
|
|
killing and yanking or providing org-mode like "move section
|
|
|
|
|
upwards/downwards" commands. However, that's not so easy in the
|
|
|
|
|
presence of multi-file documents.

* Internal changes
|
|
|
|
|
|
2007-04-13 03:01:45 +00:00
|
|
|
|
** Cleanup all the GC_ mark bit stuff -- there is no longer any distinction
|
2007-03-17 17:37:41 +00:00
|
|
|
|
since the mark bit is no longer stored in the Lisp_Object itself.
|
|
|
|
|
|
2015-08-26 21:05:43 +00:00
|
|
|
|
** Refine the 'predicate' arg to read-file-name.
|
2007-05-23 17:28:25 +00:00
|
|
|
|
Currently, it mixes up the predicate to apply when doing completion and the
|
|
|
|
|
one to use when terminating the selection.
|
|
|
|
|
|
2006-12-27 16:31:01 +00:00
|
|
|
|
** Merge ibuffer.el and buff-menu.el.
|
|
|
|
|
More specifically do what's needed to make ibuffer.el the default,
|
|
|
|
|
or just an extension of buff-menu.el.
|
|
|
|
|
|
2014-01-27 00:36:40 +00:00
|
|
|

** Replace linum.el with nlinum.el
|

|
|
|
|
|
|
2006-12-27 16:31:01 +00:00
|
|
|
|
** Merge sendmail.el and messages.el.
|
|
|
|
|
Probably not a complete merge, but at least arrange for messages.el to be
|
|
|
|
|
a derived mode of sendmail.el. Or arrange for messages.el to be split
|
|
|
|
|
into a small core and "the rest" so that we use less resources as long as
|
|
|
|
|
we stick to the features provided in sendmail.el.

2004-04-22 22:58:45 +00:00
|
|
|
|
** Replace gmalloc.c with the modified Doug Lea code from the current
|
2006-12-27 16:31:01 +00:00
|
|
|
|
GNU libc so that the special mmapping of buffers can be removed --
|
|
|
|
|
that apparently loses under Solaris, at least. [fx has mostly done
|
|
|
|
|
this.]
|
2004-04-22 22:58:45 +00:00
|
|
|
|
|
|
|
|
|
** Rewrite make-docfile to be clean and maintainable.
|
2012-06-28 07:05:15 +00:00
|
|
|
|
It might be better to replace it with Lisp, using the byte compiler.

** Add an inferior-comint-minor-mode to capture the common set of operations
|
|
|
|
|
offered by major modes that offer an associated inferior
|
2004-12-07 05:01:55 +00:00
|
|
|
|
comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic.
|
|
|
|
|
For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode,
|
|

** Add "link" button class
|
|
|
|

Add a standard button-class named "link", and make all other link-like
|
|
|
|
|
button classes inherit from it. Set the default face of the "link" button
|
|
|
|
|
class to the standard "link" face.
