8 If you are ready to start working on any of these TODO items, we
9 appreciate your help; please write to emacs-devel@gnu.org so we can be
10 aware that the problem is being addressed, and talk with you how to do
11 it best. Since Emacs is an FSF-copyrighted package, please be
12 prepared to sign legal papers to transfer the copyright on your work
13 to the FSF.
14
15 * Simple tasks. These don't require much emacs knowledge, they are
16 suitable for anyone from beginners to experts.
17
18 ** Convert modes that use view-mode to be derived from special-mode instead.
19
20 ** make emacsclient accept -nw as a synonym to -t.
21
22 ** Replace some uses of the preprocessor code in Makefile.in with the equivalent autoconf.
23
24 ** Major modes should have a menu entry. Examples of modes that do
25 not have one at the moment and probably should: text-mode, inferior-lisp-mode.
26
27 ** Check if all items on the mode-line have a suitable tooltip for all modes.
28
29 ** edebug and debugger-mode should have a toolbar.
30 It can use the same icons as gud.
31
32 ** Check what minor modes don't use define-minor-mode and convert them
33 to use it.
34
35 ** Convert all defvars with leading `*' in the doc-strings into defcustoms
36 of appropriate :type and :group.
37
38 * Small but important fixes needed in existing features:
39
40 ** Flymake's customization mechanism needs to be both simpler (fewer
41 levels of indirection) and better documented, so it is easier to
42 understand. I find it quite hard to figure out what compilation
43 command it will use.
44
45 I suggest totally rewriting that part of Flymake, using the simplest
46 mechanism that sufficies for the specific needs. That will be easy
47 for users to customize.
48
49 ** Make "emacs --daemon" start emacs without showing any frame.
50 Use emacsclient later to open frames.
51
52 ** Make it possible to reliably turn on minor modes using "mode:" in the local
53 variables section.
54
55 ** "Options -> Save Options" should save the font set via "Set Font/Fontset"
56 I.e. mouse-set-font should use customize-face.
57
58 ** Compute the list of active keymaps *after* reading the first event.
59
60 ** Distribute a bar cursor of width > 1 evenly between the two glyphs
61 on each side of the bar (what to do at the edges?).
62
63 ** buffer-offer-save should be a permanent local.
64
65 ** revert-buffer should eliminate overlays and the mark.
66 For related problems consult the thread starting with
67 http://lists.gnu.org/archive/html/emacs-devel/2005-11/msg01346.html
68
69 ** erase-buffer should perhaps disregard read-only properties of text.
70
71 ** Make occur correctly handle matches that span more than one line,
72 as well as overlapping matches.
73
74 ** Fix the kill/yank treatment of invisible text. At the moment,
75 invisible text is placed in the kill-ring, so that the contents of
76 the ring may not correspond to the text as displayed to the user.
77 It ought to be possible to omit text which is invisible (due to a
78 text-property, overlay, or selective display) from the kill-ring.
79
80 ** Change the way define-minor-mode handles autoloading.
81 It should not generate :require. Or :require in defcustom
82 should not be recorded in the user's custom-set-variables call.
83
84 ** Feature to change cursor shape when Emacs is idle (for more than
85 a specified time).
86
87 ** The buttons at the top of a custom buffer should not omit
88 variables whose values are currently hidden.
89
90 ** Clean up the variables in browse-url. Perhaps use a shell command string to
91 specify the browser instead of the mushrooming set of functions.
92 See also ESR's proposal for a BROWSER environment variable
93 <URL:http://www.catb.org/~esr/BROWSER/browse-url.patch>.
94
95 ** Enhance scroll-bar to handle tall line (similar to line-move).
96
97 ** Make occur handle multi-line matches cleanly with context.
98
99 ** In Custom buffers, put the option that turns a mode on or off first,
100 using a heuristic of some kind?
101
102 ** Define recompute-arg and recompute-arg-if for fix_command to use.
103 See rms message of 11 Dec 05.
104
105 ** Height returned by frame-parameter ... and height given to
106 make-frame does not mean the same thing. The former includes menu and
107 tool bar lines, the latter don't. frame-parameter should return height
108 without menu and tool bar lines.
109
110 ** In Emacs Info, examples of using Customize should be clickable
111 and they should create Custom buffers.
112
113 ** The toolbar should show keyboard equivalents in its tooltips.
114
115 ** Add function to redraw the tool bar.
116
117 ** M-! M-n should fetch the buffer-file-name as the default.
118
119 ** Redesign the load-history data structure so it can cope better
120 with evaluating definitions of the same function from different files,
121 recording which file the latest definition came from.
122
123 ** make back_comment use syntax-ppss or equivalent.
124
125 ** Consider improving src/sysdep.c's search for a fqdn.
126 http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00782.html
127
128 ** Find a proper fix for rcirc multiline nick adding.
129 http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00684.html
130
131 ** Implement `network-interface-list' and `network-interface-info'
132 on MS-Windows. Hint: the information is present in the Registry,
133 under the keys
134 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Linkage\
135 and
136 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<device>\
137 where <device> is the network device found under the first key.
138
139 ** Check for any included packages that define obsolete bug-reporting commands.
140 Change them to use report-emacs-bug.
141
142 ** Allow fringe indicators to display a tooltip (provide a help-echo property?)
143
144 ** Add a defcustom that supplies a function to name numeric backup files,
145 like make-backup-file-name-function for non-numeric backup files.
146
147 * Important features:
148
149 ** Having tabs above a window to switch buffers in it.
150
151 ** "Perspectives" are named persistent window configurations. We have
152 had the window configuration mechanism in GNU Emacs since the
153 beginning but we have never developed a good user interface to take
154 advantage of them. Eclipse's user interface seems to be good.
155
156 Perspectives work well even if you do the equivalent of C-x 4 C-f
157 because of the distinction between view windows vs file windows. In
158 Emacs this is more or less the "dedicated window" feature, but we have
159 never really made it work for this.
160
161 Perspectives also need to interact with the tabs.
162
163 ** Imenu could be extended into a file-structure browsing mechanism
164 using code like that of customize-groups.
165
166 ** Display something in the margin on lines that have compilation
167 errors.
168
169 ** Compilation error navigation bar, parallel to the scroll bar,
170 indicating where in the buffer there are compilation errors.
171 Perhaps we could arrange to display these error indications on top
172 of the scroll bar itself. That depends on to what extent toolkit
173 scroll bars are extensible.
174
175 ** Provide user-friendly ways to list all available font families,
176 list fonts, display a font as a sample, etc. [fx is looking at
177 multilingual font selection for the Unicode branch of Emacs.]
178
179 ** Provide a convenient way to select a color with the mouse.
180
181 ** Rewrite the face code to be simpler, clearer and faster.
182
183 ** Program Enriched mode to read and save in RTF. [Is there actually a
184 decent single definition of RTF? Maybe see info at
185 http://latex2rtf.sourceforge.net/.] This task seems to be addressed
186 by http://savannah.nongnu.org/projects/emacs-rtf/, which is still in
187 very early stages.
188
189 ** Implement something better than the current Refill mode. This
190 probably needs some primitive support.
191
192 ** Add a command to make a "Local Variables" section in the current buffer
193 and/or add a variable to the list.
194
195 ** Implement primitive and higher-level functions to allow filling
196 properly with variable-pitch faces.
197
198 ** Implement a smoother vertical scroll facility, one that allows
199 C-v to scroll through a tall image. The primitive operations
200 posn-at-point and posn-at-x-y should now make it doable in elisp.
201
202 ** Implement intelligent search/replace, going beyond query-replace
203 (see http://graphics.csail.mit.edu/~rcm/chi04.pdf).
204
205 ** Implement other text formatting properties.
206 *** Footnotes that can appear either in place or at the end of the page.
207 *** text property that says "don't break line in middle of this".
208 Don't break the line between two characters that have the
209 same value of this property.
210 *** Discretionary hyphens that are not visible when they are at end of line.
211
212 ** Internationalize Emacs's messages.
213
214 ** Set up a facility to save backtraces when errors happen during
215 specified filters, specified timers, and specified hooks.
216
217 ** Install mmc@maruska.dyndns.org's no-flicker change.
218
219 ** Add a "current vertical pixel level" value that goes with point,
220 so that motion commands can also move through tall images.
221 This value would be to point as window-vscroll is to window-start.
222
223 ** Address internationalization of symbols names essentially
224 as documentation, e.g. in command names and Custom.
225
226 ** Make the Lucid menu widget display multilingual text. [This
227 probably needs to be done from actual Emacs buffers, either directly
228 in the menu or by rendering in an unmapped window and copying the
229 pixels. The current code assumes a specific locale; that isn't good
230 enough even if X can render the arbitrary text] [The gtk
231 port now displays multilingual text in menus, but only insofar as
232 Emacs can encode it as utf-8 and gtk can display the result.]
233 Maybe making Lucid menus work like Gtk's (i.e. just force utf-8) is good
234 enough now that Emacs can encode most chars into utf-8.
235
236 ** Remove the limitation that window and frame widths and heights can
237 be only full columns/lines.
238
239 * Other features we would like:
240
241 ** Make longlines-mode wrap lines based on screen position instead
242 of character position, so that variable-width fonts can be handled
243 properly.
244
245 ** Allow frames(terminals) created by emacsclient to inherit their environment
246 from the emacsclient process.
247 ** Remove the default toggling behavior of minor modes when called from elisp
248 rather than interactively. This a trivial one-liner in easy-mode.el.
249
250 ** Create a category of errors called `user-error' for errors which are
251 typically due to pilot errors and should thus be in debug-ignored-errors.
252
253 ** Give Tar mode all the features of Archive mode.
254
255 ** Create a category of errors called `process-error'
256 for some or all errors associated with using subprocesses.
257
258 ** Maybe reinterpret `parse-error' as a category of errors
259 and put some other errors under it.
260
261 ** A function to tell you the argument pattern of functions.
262 See `function-arity' in http://www.loveshack.ukfsn.org/emacs/fx-misc.el.
263
264 ** Make byte-compile warn when a doc string is too wide.
265
266 ** Make byte-optimization warnings issue accurate line numbers.
267
268 ** A function to check for customizable options that have been
269 set but not saved, and ask the user whether to save them.
270 This could go in kill-emacs-query-functions, to remind people
271 to save their changes. If the user says yes, show them
272 in a Custom buffer using customize-customized.
273
274 ** Record the sxhash of the default value for customized variables
275 and notify the user (maybe by adding a menu item or toolbar button,
276 as the detection can occur during autoload time) when the default
277 changes (meaning that new versions of the Lisp source with a changed
278 default value got installed) and offer ediff on the respective
279 customization buffers.
280
281 ** Emacs Lisp mode could put an overlay on the defun for every
282 function that has advice. The overlay could have `after-text' like
283 " [Function has advice]". It might look like (defun foo [Function
284 has advice] (x y) The overlay could also be a button that you could
285 use to view the advice.
286
287 ** Add a function to get the insertion-type of the markers in an overlay.
288
289 ** ange-ftp
290 *** understand sftp
291 This is hard to make work because sftp doesn't print status
292 messages.
293
294 *** Use MLS for ange-ftp-insert-directory if a list of files is specified.
295
296 ** Ability to map a key, including all modified-combinations.
297 E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up
298 M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 ->
299 H-S-C-M-s-double-wheel-up, ...
300
301 ** Beefed-up syntax-tables.
302 *** recognize multi-character syntactic entities like `begin' and `end'.
303 *** nested string-delimiters (for Postscript's (foo(bar)baz) strings).
304 *** support for infix operators (with precedence).
305 *** support for the $ (paired delimiter) in parse-partial-sexp.
306 *** support for hook-chars whose effect on the parsing-state is specified
307 by elisp code. Thus a char could both close a string and open a comment
308 at the same time and do it in a context-sensitive way.
309 *** ability to add mode-specific data to the partial-parse-state.
310
311 ** Add a way to convert a keyboard macro to equivalent Lisp code.
312
313 ** Have a command suggestion help system that recognizes patterns
314 of commands which could be replaced with a simpler common command.
315 It should not make more than one suggestion per 10 minutes.
316
317 ** Add a way to define input methods by computing them (when first used)
318 from other input methods. Then redefine C-x 8 to use a
319 user-selected input method, with the default being the union of
320 latin-1-prefix and latin-1-postfix.
321
322 ** Switch the Windows port to using Unicode keyboard input (maybe).
323 Based on http://msdn2.microsoft.com/en-us/library/ms633586.aspx,
324 this boils down to (1) calling RegisterClassW function to register
325 Emacs windows, and (2) modifying ALL system messages to use Unicode.
326 In particular, WM_CHAR messages, which result from keyboard input,
327 will then come in encoded in UTF-16.
328
329 One advantage of switching to Unicode is to toss encoded-kbd usage,
330 which will solve the problem with binding non-ASCII keys with
331 modifiers.
332
333 Problem: using this on Windows 9x/ME requires installing the
334 Microsoft Layer for Unicode (MSLU), which might not implement all
335 the required functionality that is available built-in on Windows XP
336 and later. We should not make this change if it would pressure
337 users of unauthorized copies of older versions of Windows to
338 downgrade to versions that require activation.
339
340 ** Implement a clean way to use different major modes for
341 different parts of a buffer. This could be useful in editing
342 Bison input files, for instance, or other kinds of text
343 where one language is embedded in another language. See
344 http://www.loveshack.ukfsn.org/emacs/multi-mode.el and also
345 mmm-mode, as reference for approaches took by others.
346
347 ** Arrange a way for an input method to return the first character
348 immediately, then replace it later. So that C-s a with
349 input method latin-1-postfix would immediately search for an a.
350
351 ** Give start-process the ability to direct standard-error
352 output to a different filter.
353
354 ** Make desktop.el save the "frame configuration" of Emacs (in some
355 useful sense).
356
357 ** Give desktop.el a feature to switch between different named
358 desktops.
359
360 ** Replace finder.el with something that generates an Info file
361 which gives the same information through a menu structure. [Dave
362 Love started on this.]
363
364 ** Add a cpio mode, more or less like tar mode.
365
366 ** Implement a variant of uncompress.el or jka-compr.el that works with
367 GNU Privacy Guard for encryption. [Code exists but isn't assigned.
368 See the Gnus development sources for assigned code concerning GPG
369 use with mail, which is probably a good start.] See also
370 http://www.loveshack.ukfsn.org/emacs/auto-crypt.tgz.
371
372 ** Save undo information in special temporary files, and reload it
373 when needed for undoing. This could extend undo capacity.
374
375 ** Change the Windows NT menu code
376 so that it handles the deep_p argument and avoids
377 regenerating the whole menu bar menu tree except
378 when the user tries to use the menubar.
379
380 This requires the RIT to forward the WM_INITMENU message to
381 the main thread, and not return from that message until the main
382 thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated
383 the whole menu bar. In the mean time, it should process other messages.
384
385 ** Get some major packages installed: W3 (development version needs
386 significant work), PSGML, _possibly_ Cedet and ECB.
387 http://lists.gnu.org/archive/html/emacs-devel/2007-05/msg01493.html
388 Check the assignments file for other packages which might go in and
389 have been missed.
390
391 ** Possibly install python-mode in place of python.el, or combine the two.
392 Someone needs to do the work of figuring out who all the non-trivial
393 python-mode.el contributors are and getting assignments.
394 http://lists.gnu.org/archive/html/emacs-devel/2008-02/msg02156.html
395 http://lists.gnu.org/archive/html/emacs-devel/2008-02/msg02201.html
396 http://lists.gnu.org/archive/html/emacs-devel/2008-02/msg02489.html
397 http://lists.gnu.org/archive/html/emacs-devel/2008-02/msg02234.html
398
399 ** Make keymaps a first-class Lisp object (this means a rewrite of
400 keymap.c). What should it do apart from being opaque ?
401 multiple inheritance ? faster where-is ? no more fix_submap_inheritance ?
402 what else ?
403
404 ** Provide real menus on ttys. The MS-DOS implementation can serve as
405 an example how to do part of this; see the XMenu* functions on msdos.c.
406
407 ** Implement popular parts of the rest of the CL functions as compiler
408 macros in cl-macs.
409
410 ** Make compiler warnings about functions that might be undefined at run time
411 smarter, so that they know which files are required by the file being
412 compiled and don't warn about functions defined in them.
413
414 ** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA,
415 but it's a valuable feature worth making more general.
416
417 ** Provide MIME support for Rmail using the Gnus MIME library. [Maybe
418 not now feasible, given Gnus maintenance decisions. fx looked at
419 this and can say where some of the problems are.]
420
421 ** Eliminate the storm of warnings concerning char/unsigned char
422 mismatches that we get with GCC 4.x and proprietary compilers on
423 various systems. They make it difficult to spot the important
424 warnings.
425
426 ** Fix anything necessary to use `long long' EMACS_INTs with GCC.
427
428 ** Split out parts of lisp.h and generate Makefile dependencies
429 automatically.
430
431 ** Update the FAQ.
432
433 ** Allow auto-compression-mode to use zlib calls if zlib is available.
434 [It's required for PNG, so may be linked anyhow.]
435
436 ** Add a --pristine startup flag which does -q --no-site-file plus
437 ignoring X resources (Doze equivalents?) and most of the
438 environment. What should not be ignored needs consideration.
439 [Do the existing -Q and -D cover this, or is more needed?]
440
441 ** Improve the GC (generational, incremental). (We may be able to use
442 the Boehm collector.) [See the Boehm-GC branch in CVS for work on
443 this.]
444
445 ** Check what hooks would help Emacspeak -- see the defadvising in W3.
446
447 ** Add definitions for symbol properties, for documentation purposes.
448
449 ** Add horizontal scroll bars.
450
451 ** Provide an optional feature which computes a scroll bar slider's
452 size and its position from lines instead of characters.
453
454 ** Allow unknown image types to be rendered via an external program
455 converting them to, say, PBM (in the same way as PostScript?). [does
456 doc-view.el do this, or could it be extended to do this?]
457
458 ** Allow displaying an X window from an external program in a buffer,
459 e.g. to render graphics from Java applets. [gerd and/or wmperry
460 thought this was feasible.]
461
462 ** Allow images (not just text) in the margin to be mouse-sensitive.
463 (Requires recursing through display properties). Provide some way
464 to simulate mouse-clicks on marginal text without a mouse.
465
466 ** Implement Lisp functions to determine properly whether a character
467 is displayable (particularly needed in XFree 4, sigh). Use it to
468 define useful glyphs that may be displayed as images or unicodes
469 (with ASCIIfied fallback via latin1-disp). Examples include
470 box-drawing graphics in Custom buffers, W3 rules and tables, and
471 tree displays generally, mode-line mail indicator. [See work done
472 already for Emacs 23 and consult fx.]
473
474 ** Do something to make rms happy with fx's dynamic loading, and use it
475 to implement things like auto-loaded buffer parsers and database
476 access in cases which need more than Lisp.
477
478 ** Extend ps-print to deal with multiple font sizes, images, and extra
479 encodings.
480
481 ** Provide portable undumping using mmap (per gerd design).
482
483 ** Make byte-compile avoid binding an expanded defsubst's args
484 when the body only calls primitives.
485
486 ** Use the XIE X extension, if available, for image display.
487
488 ** Make monochrome images display using the foreground and background
489 colors of the applicable faces.
490
491 ** Face remapping.
492
493 ** Make `format-time-string' preserve text properties like `format'.
494
495 ** Optionally make the cursor a little thinner at the end of a line
496 or the end of the buffer.
497
498 ** Port the conservative stack marking code of Emacs' garbage collector
499 to more systems, so that we can completely get rid of GCPROs. Note
500 that Boehm garbage collector provides this.
501
502 ** Reorder defcustom's in each package so that the more important
503 options come first in the Customize buffers. This could be done by
504 either rearranging the file (since options are shown in the order
505 they appear in the *.el files), or by adding a few :set-after
506 attributes.
507
508 ** Maybe document the features of libraries missing from the manual (or
509 ancillary manuals, including the Lisp manual in some cases).
510 This is not worth doing for all of these packages and we need not
511 aim for completeness, but some may be worth documenting.
512
513 Here's a list which is probably not complete/correct: align, allout,
514 artist, ansi-color, array, battery, calculator, cdl, cmuscheme,
515 completion, cua, delim-col, dirtrack, double, echistory, elide-head,
516 easymenu, expand, flow-ctrl, format [format-alist],
517 generic/generic-x [various modes], kermit, log-edit, ledit
518 [obsolete?], makesum, midnight [other than in Kill Buffer node],
519 mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile,
520 snmp-mode [?], soundex [should be interactive?], strokes [start from

528
529 ** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap
530 the XPMs so that the color versions work generally. (Requires care
531 with the color used for the transparent regions.)
532
533 ** Convenient access to the `values' variable. It would be nice to have an
534 interface that would show you the printed reps of the elements of the
535 list in a menu, let you select one of the values, and put it into some
536 other variable, without changing the value of `values'.
537
538 ** (Controlled by a flag) make open and close syntax match exactly,
539 i.e. `(' doesn't match `]'.
540
541 ** Specify parameter ID-FORMAT in all calls to `file-attributes' and
542 `directory-files-and-attributes' where attributes UID or GID are used.
543 Whenever possible, use value 'string.
544 When done, change meaning of default value from 'integer to 'string.
545 If value 'integer is used nowhere, remove the parameter ID-FORMAT from
546 the definition of `file-attributes' and `directory-files-and-attributes'
547 and from the calls.
548
549 ** Make language-info-alist customizable. Currently a user can customize
550 only the variable `current-language-environment'.
551
552 ** Improve language environment handling so that Emacs can fit
553 better to a users locale. Currently Emacs uses utf-8 language
554 environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale
555 are also put in utf-8 lang. env. In such a case, it is
556 better to use Japanese lang. env. but prefer utf-8 coding system.
557
558 ** Enhance locale handling: handle language, territory and charset
559 orthogonally and de-emphasize language environments. Use the locale
560 to set up more things, such as fontsets, the default Ispell
561 dictionary, diary format, calendar holidays and display, quoting
562 characters and phrase boundaries, sentence endings, collation for
563 sorting (at least for unicodes), HTTP Accept-language, patterns for
564 directory listings and compilation messages, yes-or-no replies,
565 common menu items when the toolkit supports it ... `locale-info'
566 needs extending for LC_COLLATE &c. [fx started on this.]
567
568 ** Eliminate the current restriction on header printing by ps-print.
569 Currently, a header can contain only single 1-byte charset in
570 addition to ASCII.
571
572 ** In ps-print, provide an user friendly interface to specify fonts.
573
574 ** Enhance word boundary detection for such a script that doesn't use
575 space at word boundary (e.g. Thai).
576
577 ** Implement interface programs with major Japanese conversion server
578 in lib-src so that they can be used from the input method
579 "japanese". Currently, most Japanese users are using external
580 packages (e.g. tamago, anthy) or an input method via XIM.
581
582 ** Let LEIM handle the Mode_switch key like XIM does (i.e. a toggle like C-\
583 but which can also be used as a modifier).
584
585 ** Improve Help buffers: Change the face of previously visited links (like
586 Info, but also with regard to namespace), add a forward button to make the
587 Help buffer more browser like and gives the value of lisp expressions
588 e.g auto-mode-alist, the right face. [nickrob@snap.net.nz has a patch
589 for this for inclusion after 22.1].
590
591 ** Possibly make `list-holidays' eval items in the calendar-holidays variable.
592 See thread
593 <http://lists.gnu.org/archive/html/emacs-devel/2006-02/msg01034.html>.
594 [rgm@gnu.org will look at this after 22.1]
595
596 ** Possibly make cal-dst use the system timezone database directly.
597 See thread
598 <http://lists.gnu.org/archive/html/emacs-pretest-bug/2006-11/msg00060.html>
599
600 ** Possibly add a "close" button to the modeline.
601 The idea is to add an "X" of some kind, that when clicked deletes
602 the window associated with that modeline.
603 http://lists.gnu.org/archive/html/emacs-devel/2007-09/msg02416.html
604
605 * Internal changes
606
607 ** Cleanup all the GC_ mark bit stuff -- there is no longer any distinction
608 since the mark bit is no longer stored in the Lisp_Object itself.
609
610 ** Refine the `predicate' arg to read-file-name.
611 Currently, it mixes up the predicate to apply when doing completion and the
612 one to use when terminating the selection.
613
614 ** Merge ibuffer.el and buff-menu.el.
615 More specifically do what's needed to make ibuffer.el the default,
616 or just an extension of buff-menu.el.
617
618 ** Use pcomplete by default in shell-mode.
619 This means to make it behave (by default) more like the current code.
620 Use it also for read-shell-command, M-x compile, ...
621
622 ** Merge sendmail.el and messages.el.
623 Probably not a complete merge, but at least arrange for messages.el to be
624 a derived mode of sendmail.el. Or arrange for messages.el to be split
625 into a small core and "the rest" so that we use less resources as long as
626 we stick to the features provided in sendmail.el.
627
628 ** Replace gmalloc.c with the modified Doug Lea code from the current
629 GNU libc so that the special mmapping of buffers can be removed --
630 that apparently loses under Solaris, at least. [fx has mostly done
631 this.]
632
633 ** Rewrite make-docfile to be clean and maintainable.
634
635 ** Add an inferior-comint-minor-mode to capture the common set of operations
636 offered by major modes that offer an associated inferior
637 comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic.
638 For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode,
639 haskell-mode, tuareg-mode, ...
640
641 ** Make SYNC_INPUT the default.
642 All loops using immediate_quit need to be checked to ensure that
643 C-g can interrupt them, in case of an infinite loop. Once we
644 switch to using SYNC_INPUT, we can remove the BLOCK_INPUTs in the
645 allocation functions (allocate_string etc.) without worrying about
646 data munging.
647
648 ** Add "link" button class
649 Add a standard button-class named "link", and make all other link-like
650 button classes inherit from it. Set the default face of the "link" button
651 class to the standard "link" face.
652
653 * Other known bugs:
654
655 ** `make-frame' forgets unhandled parameters, at least for X11 frames.
656 ** The \\{...} keymap dump output does not correctly remove shadowed entries:
