Small but important fixes needed in existing features:
-* Bring back the feature of showing the part of the buffer that is a problem
- for the use of the preferred coding systems.
-
* Make compile.el record the markers that point to error loci
on text properties in the error message lines.
Important features:
* Provide user-friendly ways to list all available font families,
- display a font as a sample, etc.
+ display a font as a sample, etc. [fx is looking at multilingual
+ font selection for Emacs 22.]
* Program Enriched mode to read and save in RTF. [Is there actually a
decent single definition of RTF?]
* Implement primitive and higher-level functions to allow filling
properly with variable-pitch faces.
-* Implement a smoother vertical scroll facility.
+* Implement a smoother vertical scroll facility, one that allows
+ C-v to scroll through a tall image.
* Implement other text formatting properties.
** Footnotes that can appear either in place or at the end of the page.
* Make movemail work with IMAP.
-* Internationalize Emacs's messages.
-
-* Port Emacs to GTK+. (Relevant work has been done already.)
+* Internationalize Emacs's messages. [Note that this is of limited
+ use until the menus can display multilingual text. It also doesn't
+ address important issues like using the names of symbols essentially
+ as documentation, e.g. in command names and Custom. -- fx]
-* Make the Lucid menu widget display multilingual text.
+* Make the Lucid menu widget display multilingual text. [This
+ probably needs to be done from actual Emacs buffers, either directly
+ in the menu or by rendering in an unmapped window and copying the
+ pixels. Note that the relevant Xlib functions assume a specific
+ locale; that isn't good enough even if X can render the arbitrary
+ text, which it often can't as far as I can tell. -- fx]
* Remove the limitation that window and frame widths and heights can
be only full columns/lines.
+* Move fringe to be displayed between display margins and text area.
+ [KFS is looking into this].
+
+* Set fringe widths per-window/per-buffer.
+
+* Make fringe bitmaps user configurable. Maybe add ability to add
+ additional bitmaps to the fringe from lisp.
+
Other features we would like:
* Have a command suggestion help system that recognizes patterns
of commands which could be replaced with a simpler common command.
It should not make more than one suggestion per 10 minutes.
+* Add a way to define input methods by computing them (when first used)
+ from other input methods. Then redefine C-x 8 to use a
+ user-selected input method, with the default being the union of
+ latin-1-prefix and latin-1-postfix.
+
* Implement a clean way to use different major modes for
different parts of a buffer.
Love started on this.]
* Implement a variant of uncompress.el or jka-compr.el that works with
- GNU Privacy Guard for encryption. [Code exists but isn't assigned.]
+ GNU Privacy Guard for encryption. [Code exists but isn't assigned.
+ See the Gnus development sources for assigned code concerning GPG
+ use with mail, which is probably a good start.]
* Save undo information in files, and reload it when needed
for undoing.
* Merge the Emacs regex.c with the Glibc regex.c.
- They split off a few years ago through negligance.
+ They split off a few years ago through negligence.
* Change the Windows NT menu code
so that it handles the deep_p argument and avoids

the main thread, and not return from that message until the main

- assignments file for other packages which might go in and have been
- missed.
+ significant work), PSGML. Check the assignments file for other
+ packages which might go in and have been missed.
* Make keymaps a first-class Lisp object (this means a rewrite of
keymap.c). What should it do apart from being opaque ?
* Implement popular parts of the rest of the CL functions as compiler
macros in cl-macs.
-* Highlight rectangles (`mouse-track-rectangle-p' in XEmacs).
+* Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA,
+ but it's a valuable feature worth making more general.
* Support simultaneous tty and X frames.
-* Provide MIME support for Rmail using the Gnus MIME library.
+* Provide MIME support for Rmail using the Gnus MIME library. [Maybe
+ not now feasible, given Gnus maintenance decisions. fx looked at
+ this and can say where some of the problems are.]
* Eliminate the storm of warnings concerning char/unsigned char
mismatches that we get with proprietary compilers on various systems.
holidays, quoting characters?,...
* Improve the GC (generational, incremental). (We may be able to use
- the Boehm collector.)
+ the Boehm collector.) [fx is working on this.]
* Check what hooks would help Emacspeak -- see the defadvising in W3.
* Provide an optional feature which computes a scroll bar slider's
size and its position from lines instead of characters.
-* Integrate Vroonhof's Custom themes code and make it do useful
- things. [The integration is partly done.]
-
-* Adapt the gnuserv/gnudoit features for server/emacsclient.
+* Make the Custom themes support do useful things.
* Investigate using GNU Lightning or similar system for incremental
compilation of selected bytecode functions to subrs. Converting CCL
* Add a feature to Info similar to "info --apropos SUBJECT".
-* If you do an insert-file and that file is currently modified in
- another buffer but not written yet, print a warning.
-
-* Add support for SVG (Scalable Vector Graphics) rendering to
+* Add support for SVG (Scalable Vector Graphics) rendering to
Emacs.
+* Allow unknown image types to be rendered via an external program
+ converting them to, say, PBM (in the same way as PostScript?).
+
+* Allow displaying an X window from an external program in a buffer,
+ e.g. to render graphics from Java applets. [gerd and/or wmperry
+ thought this was feasible.]
+
+* Allow images (not just text) in the margin to be mouse-sensitive.
+ (Requires recursing through display properties). Provide some way
+ to simulate mouse-clicks on marginal text without a mouse.
+
+* Implement Lisp functions to determine properly whether a character
+ is displayable (particularly needed in XFree 4, sigh). Use it to
+ define useful glyphs that may be displayed as images or unicodes
+ (with ASCIIfied fallback via latin1-disp). Examples include
+ box-drawing graphics in Custom buffers, W3 rules and tables, and
+ tree displays generally, mode-line mail indicator. [See work done
+ already for Emacs 22 and consult fx.]
+
+* Do something to make rms happy 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.
+
+* Extend ps-print to deal with multiple font sizes, images, and extra
+ encodings.
+
+* Provide portable undumping using mmap (per gerd design).
+
+* Replace gmalloc.c with the modified Doug Lea code from the current
+ GNU libc so that the special mmapping of buffers can be removed --
+ that apparently loses under Solaris, at least. [fx has mostly done
+ this.]
+
* Use the XIE X extension, if available, for image display.
-* Add support for rendering antialiased text, probably using FreeType.
+* Make monochrome images display using the foreground and background
+ colors of the applicable faces.
+
+* Add support for rendering antialiased text, probably using
+ XRender/Freetype.
-* Rewrite make-docfile to something sane.
+* Rewrite make-docfile to be clean and maintainable.
* Port the conservative stack marking code of Emacs' garbage collector
to more systems, so that we can completely get rid of GCPROs.
+* Reorder defcustom's in each package so that the more important
+ options come first in the Customize buffers. This could be done by
+ either rearranging the file (since options are shown in the order
+ they appear in the *.el files), or by adding a few :set-after
+ attributes.
+
* Maybe document the features of libraries missing from the manual (or
ancillary manuals, including the Lisp manual in some cases).
This is not worth doing for all of these packages and we need not

+
+* Provide a means to extract image-relative coordinates from mouse
+ clicks on images. (Needed for W3, at least.) Also useful for W3
+ and Gnus: allow images to scroll properly.
+
+* Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap
+ the XPMs so that the colour versions work generally. (Requires care
+ with the colour used for the transparent regions.)
+
+* Convenient access to the `values' variable. It would be nice to have an
+ interface that would show you the printed reps of the elements of the
+ list in a menu, let you select one of the values, and put it into some
+ other variable, without changing the value of `values'.
+
+* Fix skip-chars-{for,back}ward to allow character classes.
