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

527
528 ** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap
529 the XPMs so that the color versions work generally. (Requires care
530 with the color used for the transparent regions.)
531
532 ** Convenient access to the `values' variable. It would be nice to have an
533 interface that would show you the printed reps of the elements of the
534 list in a menu, let you select one of the values, and put it into some
535 other variable, without changing the value of `values'.
536
537 ** (Controlled by a flag) make open and close syntax match exactly,
538 i.e. `(' doesn't match `]'.
539
540 ** Specify parameter ID-FORMAT in all calls to `file-attributes' and
541 `directory-files-and-attributes' where attributes UID or GID are used.
542 Whenever possible, use value 'string.
543 When done, change meaning of default value from 'integer to 'string.
544 If value 'integer is used nowhere, remove the parameter ID-FORMAT from
545 the definition of `file-attributes' and `directory-files-and-attributes'
546 and from the calls.
547
548 ** Make language-info-alist customizable. Currently a user can customize
549 only the variable `current-language-environment'.
550
551 ** Improve language environment handling so that Emacs can fit
552 better to a users locale. Currently Emacs uses utf-8 language
553 environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale
554 are also put in utf-8 lang. env. In such a case, it is
555 better to use Japanese lang. env. but prefer utf-8 coding system.
556
557 ** Enhance locale handling: handle language, territory and charset
558 orthogonally and de-emphasize language environments. Use the locale
559 to set up more things, such as fontsets, the default Ispell
560 dictionary, diary format, calendar holidays and display, quoting
561 characters and phrase boundaries, sentence endings, collation for
562 sorting (at least for unicodes), HTTP Accept-language, patterns for
563 directory listings and compilation messages, yes-or-no replies,
564 common menu items when the toolkit supports it ... `locale-info'
565 needs extending for LC_COLLATE &c. [fx started on this.]
566
567 ** Eliminate the current restriction on header printing by ps-print.
568 Currently, a header can contain only single 1-byte charset in
569 addition to ASCII.
570
571 ** In ps-print, provide an user friendly interface to specify fonts.
572
573 ** Enhance word boundary detection for such a script that doesn't use
574 space at word boundary (e.g. Thai).
575
576 ** Implement interface programs with major Japanese conversion server
577 in lib-src so that they can be used from the input method
578 "japanese". Currently, most Japanese users are using external
579 packages (e.g. tamago, anthy) or an input method via XIM.
580
581 ** Let LEIM handle the Mode_switch key like XIM does (i.e. a toggle like C-\
582 but which can also be used as a modifier).
583
584 ** Improve Help buffers: Change the face of previously visited links (like
585 Info, but also with regard to namespace), add a forward button to make the
586 Help buffer more browser like and gives the value of lisp expressions
587 e.g auto-mode-alist, the right face. [nickrob@snap.net.nz has a patch
588 for this for inclusion after 22.1].
589
590 ** Possibly make `list-holidays' eval items in the calendar-holidays variable.
591 See thread
592 <http://lists.gnu.org/archive/html/emacs-devel/2006-02/msg01034.html>.
593 [rgm@gnu.org will look at this after 22.1]
594
595 ** Possibly make cal-dst use the system timezone database directly.
596 See thread
597 <http://lists.gnu.org/archive/html/emacs-pretest-bug/2006-11/msg00060.html>
598
599 ** Possibly add a "close" button to the modeline.
600 The idea is to add an "X" of some kind, that when clicked deletes
601 the window associated with that modeline.
602 http://lists.gnu.org/archive/html/emacs-devel/2007-09/msg02416.html
603
604 * Internal changes
605
606 ** Cleanup all the GC_ mark bit stuff -- there is no longer any distinction
607 since the mark bit is no longer stored in the Lisp_Object itself.
608
609 ** Refine the `predicate' arg to read-file-name.
610 Currently, it mixes up the predicate to apply when doing completion and the
611 one to use when terminating the selection.
612
613 ** Merge ibuffer.el and buff-menu.el.
614 More specifically do what's needed to make ibuffer.el the default,
615 or just an extension of buff-menu.el.
616
617 ** Use pcomplete by default in shell-mode.
618 This means to make it behave (by default) more like the current code.
619 Use it also for read-shell-command, M-x compile, ...
620
621 ** Merge sendmail.el and messages.el.
622 Probably not a complete merge, but at least arrange for messages.el to be
623 a derived mode of sendmail.el. Or arrange for messages.el to be split
624 into a small core and "the rest" so that we use less resources as long as
625 we stick to the features provided in sendmail.el.
626
627 ** Replace gmalloc.c with the modified Doug Lea code from the current
628 GNU libc so that the special mmapping of buffers can be removed --
629 that apparently loses under Solaris, at least. [fx has mostly done
630 this.]
631
632 ** Rewrite make-docfile to be clean and maintainable.
633
634 ** Add an inferior-comint-minor-mode to capture the common set of operations
635 offered by major modes that offer an associated inferior
636 comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic.
637 For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode,
638 haskell-mode, tuareg-mode, ...
639
640 ** Make SYNC_INPUT the default.
641 All loops using immediate_quit need to be checked to ensure that
642 C-g can interrupt them, in case of an infinite loop. Once we
643 switch to using SYNC_INPUT, we can remove the BLOCK_INPUTs in the
644 allocation functions (allocate_string etc.) without worrying about
645 data munging.
646
647 ** Add "link" button class
648 Add a standard button-class named "link", and make all other link-like
649 button classes inherit from it. Set the default face of the "link" button
650 class to the standard "link" face.
651
652 * Other known bugs:
653
654 ** `make-frame' forgets unhandled parameters, at least for X11 frames.
655 ** The \\{...} keymap dump output does not correctly remove shadowed entries:
656 From: "Drew Adams" <drew.adams@oracle.com>
