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 ** Remove any leading `*'s from defcustom doc-strings.
39
40 ** Remove unnecessary autoload cookies from defcustoms.
41 This needs a bit of care, since often people have become used to
42 expecting such variables to always be defined, eg when they modify
43 things in their .emacs.
44
45 * Small but important fixes needed in existing features:
46
47 ** Flymake's customization mechanism needs to be both simpler (fewer
48 levels of indirection) and better documented, so it is easier to
49 understand. I find it quite hard to figure out what compilation
50 command it will use.
51
52 I suggest totally rewriting that part of Flymake, using the simplest
53 mechanism that sufficies for the specific needs. That will be easy
54 for users to customize.
55
56 ** Make "emacs --daemon" start emacs without showing any frame.
57 Use emacsclient later to open frames.
58
59 ** Compute the list of active keymaps *after* reading the first event.
60
61 ** Distribute a bar cursor of width > 1 evenly between the two glyphs
62 on each side of the bar (what to do at the edges?).
63
64 ** buffer-offer-save should be a permanent local.
65
66 ** revert-buffer should eliminate overlays and the mark.
67 For related problems consult the thread starting with
68 http://lists.gnu.org/archive/html/emacs-devel/2005-11/msg01346.html
69
70 ** erase-buffer should perhaps disregard read-only properties of text.
71
72 ** Make occur correctly handle matches that span more than one line,
73 as well as overlapping matches.
74
75 ** Fix the kill/yank treatment of invisible text. At the moment,
76 invisible text is placed in the kill-ring, so that the contents of
77 the ring may not correspond to the text as displayed to the user.
78 It ought to be possible to omit text which is invisible (due to a
79 text-property, overlay, or selective display) from the kill-ring.
80
81 ** Change the way define-minor-mode handles autoloading.
82 It should not generate :require. Or :require in defcustom
83 should not be recorded in the user's custom-set-variables call.
84
85 ** Feature to change cursor shape when Emacs is idle (for more than
86 a specified time).
87
88 ** The buttons at the top of a custom buffer should not omit
89 variables whose values are currently hidden.
90
91 ** Clean up the variables in browse-url. Perhaps use a shell command string to
92 specify the browser instead of the mushrooming set of functions.
93 See also ESR's proposal for a BROWSER environment variable
94 <URL:http://www.catb.org/~esr/BROWSER/browse-url.patch>.
95
96 ** Enhance scroll-bar to handle tall line (similar to line-move).
97
98 ** Make occur handle multi-line matches cleanly with context.
99
100 ** In Custom buffers, put the option that turns a mode on or off first,
101 using a heuristic of some kind?
102
103 ** Define recompute-arg and recompute-arg-if for fix_command to use.
104 See rms message of 11 Dec 05.
105
106 ** Height returned by frame-parameter ... and height given to
107 make-frame does not mean the same thing. The former includes menu and
108 tool bar lines, the latter don't. frame-parameter should return height
109 without menu and tool bar lines.
110
111 ** In Emacs Info, examples of using Customize should be clickable
112 and they should create Custom buffers.
113
114 ** The toolbar should show keyboard equivalents in its tooltips.
115
116 ** Add function to redraw the tool bar.
117
118 ** M-! M-n should fetch the buffer-file-name as the default.
119
120 ** Redesign the load-history data structure so it can cope better
121 with evaluating definitions of the same function from different files,
122 recording which file the latest definition came from.
123
124 ** make back_comment use syntax-ppss or equivalent.
125
126 ** Consider improving src/sysdep.c's search for a fqdn.
127 http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00782.html
128
129 ** Find a proper fix for rcirc multiline nick adding.
130 http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00684.html
131
132 ** Implement `network-interface-list' and `network-interface-info'
133 on MS-Windows. Hint: the information is present in the Registry,
134 under the keys
135 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Linkage\
136 and
137 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<device>\
138 where <device> is the network device found under the first key.
139
140 ** Check for any included packages that define obsolete bug-reporting commands.
141 Change them to use report-emacs-bug.
142
143 ** Allow fringe indicators to display a tooltip (provide a help-echo property?)
144
145 ** Add a defcustom that supplies a function to name numeric backup files,
146 like make-backup-file-name-function for non-numeric backup files.
147
148 ** `dired-mode' should specify the semantics of `buffer-modified-p' for
149 dired buffers and DTRT WRT `auto-revert-mode'.
150
151 ** Check uses of prin1 for error-handling.
152 http://lists.gnu.org/archive/html/emacs-devel/2008-08/msg00456.html
153
154 * Important features:
155
156 ** Having tabs above a window to switch buffers in it.
157
158 ** "Perspectives" are named persistent window configurations. We have
159 had the window configuration mechanism in GNU Emacs since the
160 beginning but we have never developed a good user interface to take
161 advantage of them. Eclipse's user interface seems to be good.
162
163 Perspectives work well even if you do the equivalent of C-x 4 C-f
164 because of the distinction between view windows vs file windows. In
165 Emacs this is more or less the "dedicated window" feature, but we have
166 never really made it work for this.
167
168 Perspectives also need to interact with the tabs.
169
170 ** Imenu could be extended into a file-structure browsing mechanism
171 using code like that of customize-groups.
172
173 ** Display something in the margin on lines that have compilation
174 errors.
175
176 ** Compilation error navigation bar, parallel to the scroll bar,
177 indicating where in the buffer there are compilation errors.
178 Perhaps we could arrange to display these error indications on top
179 of the scroll bar itself. That depends on to what extent toolkit
180 scroll bars are extensible.
181
182 ** Provide user-friendly ways to list all available font families,
183 list fonts, display a font as a sample, etc. [fx is looking at
184 multilingual font selection for the Unicode branch of Emacs.]
185
186 ** Provide a convenient way to select a color with the mouse.
187
188 ** Rewrite the face code to be simpler, clearer and faster.
189
190 ** Program Enriched mode to read and save in RTF. [Is there actually a
191 decent single definition of RTF? Maybe see info at
192 http://latex2rtf.sourceforge.net/.] This task seems to be addressed
193 by http://savannah.nongnu.org/projects/emacs-rtf/, which is still in
194 very early stages.
195
196 ** Implement primitive and higher-level functions to allow filling
197 properly with variable-pitch faces.
198
199 ** Implement a smoother vertical scroll facility, one that allows
200 C-v to scroll through a tall image. The primitive operations
201 posn-at-point and posn-at-x-y should now make it doable in elisp.
202
203 ** Implement intelligent search/replace, going beyond query-replace
204 (see http://graphics.csail.mit.edu/~rcm/chi04.pdf).
205
206 ** Implement other text formatting properties.
207 *** Footnotes that can appear either in place or at the end of the page.
208 *** text property that says "don't break line in middle of this".
209 Don't break the line between two characters that have the
210 same value of this property.
211 *** Discretionary hyphens that are not visible when they are at end of line.
212
213 ** Internationalize Emacs's messages.
214
215 ** Set up a facility to save backtraces when errors happen during
216 specified filters, specified timers, and specified hooks.
217
218 ** Install mmc@maruska.dyndns.org's no-flicker change.
219
220 ** Add a "current vertical pixel level" value that goes with point,
221 so that motion commands can also move through tall images.
222 This value would be to point as window-vscroll is to window-start.
223
224 ** Address internationalization of symbols names essentially
225 as documentation, e.g. in command names and Custom.
226
227 ** Make the Lucid menu widget display multilingual text. [This
228 probably needs to be done from actual Emacs buffers, either directly
229 in the menu or by rendering in an unmapped window and copying the
230 pixels. The current code assumes a specific locale; that isn't good
231 enough even if X can render the arbitrary text] [The gtk
232 port now displays multilingual text in menus, but only insofar as
233 Emacs can encode it as utf-8 and gtk can display the result.]
234 Maybe making Lucid menus work like Gtk's (i.e. just force utf-8) is good
235 enough now that Emacs can encode most chars into utf-8.
236
237 ** Remove the limitation that window and frame widths and heights can
238 be only full columns/lines.
239
240 * Other features we would like:
241
242 ** Make longlines-mode wrap lines based on screen position instead
243 of character position, so that variable-width fonts can be handled
244 properly.
245
246 ** Allow frames(terminals) created by emacsclient to inherit their environment
247 from the emacsclient process.
248 ** Remove the default toggling behavior of minor modes when called from elisp
249 rather than interactively. This a trivial one-liner in easy-mode.el.
250
251 ** Create a category of errors called `user-error' for errors which are
252 typically due to pilot errors and should thus be in debug-ignored-errors.
253
254 ** Give Tar mode all the features of Archive mode.
255
256 ** Create a category of errors called `process-error'
257 for some or all errors associated with using subprocesses.
258
259 ** Maybe reinterpret `parse-error' as a category of errors
260 and put some other errors under it.
261
262 ** A function to tell you the argument pattern of functions.
263 See `function-arity' in http://www.loveshack.ukfsn.org/emacs/fx-misc.el.
264
265 ** Make byte-compile warn when a doc string is too wide.
266
267 ** Make byte-optimization warnings issue accurate line numbers.
268
269 ** A function to check for customizable options that have been
270 set but not saved, and ask the user whether to save them.
271 This could go in kill-emacs-query-functions, to remind people
272 to save their changes. If the user says yes, show them
273 in a Custom buffer using customize-customized.
274
275 ** Record the sxhash of the default value for customized variables
276 and notify the user (maybe by adding a menu item or toolbar button,
277 as the detection can occur during autoload time) when the default
278 changes (meaning that new versions of the Lisp source with a changed
279 default value got installed) and offer ediff on the respective
280 customization buffers.
281
282 ** Emacs Lisp mode could put an overlay on the defun for every
283 function that has advice. The overlay could have `after-text' like
284 " [Function has advice]". It might look like (defun foo [Function
285 has advice] (x y) The overlay could also be a button that you could
286 use to view the advice.
287
288 ** Add a function to get the insertion-type of the markers in an overlay.
289
290 ** ange-ftp
291 *** understand sftp
292 This is hard to make work because sftp doesn't print status
293 messages.
294
295 *** Use MLS for ange-ftp-insert-directory if a list of files is specified.
296
297 ** Ability to map a key, including all modified-combinations.
298 E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up
299 M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 ->
300 H-S-C-M-s-double-wheel-up, ...
301
302 ** Beefed-up syntax-tables.
303 *** recognize multi-character syntactic entities like `begin' and `end'.
304 *** nested string-delimiters (for Postscript's (foo(bar)baz) strings).
305 *** support for infix operators (with precedence).
306 *** support for the $ (paired delimiter) in parse-partial-sexp.
307 *** support for hook-chars whose effect on the parsing-state is specified
308 by elisp code. Thus a char could both close a string and open a comment
309 at the same time and do it in a context-sensitive way.
310 *** ability to add mode-specific data to the partial-parse-state.
311
312 ** Add a way to convert a keyboard macro to equivalent Lisp code.
313
314 ** Have a command suggestion help system that recognizes patterns
315 of commands which could be replaced with a simpler common command.
316 It should not make more than one suggestion per 10 minutes.
317
318 ** Add a way to define input methods by computing them (when first used)
319 from other input methods. Then redefine C-x 8 to use a
320 user-selected input method, with the default being the union of
321 latin-1-prefix and latin-1-postfix.
322
323 ** Switch the Windows port to using Unicode keyboard input (maybe).
324 Based on http://msdn2.microsoft.com/en-us/library/ms633586.aspx,
325 this boils down to (1) calling RegisterClassW function to register
326 Emacs windows, and (2) modifying ALL system messages to use Unicode.
327 In particular, WM_CHAR messages, which result from keyboard input,
328 will then come in encoded in UTF-16.
329
330 One advantage of switching to Unicode is to toss encoded-kbd usage,
331 which will solve the problem with binding non-ASCII keys with
332 modifiers.
333
334 Problem: using this on Windows 9x/ME requires installing the
335 Microsoft Layer for Unicode (MSLU), which might not implement all
336 the required functionality that is available built-in on Windows XP
337 and later. We should not make this change if it would pressure
338 users of unauthorized copies of older versions of Windows to
339 downgrade to versions that require activation.
340
341 ** Implement a clean way to use different major modes for
342 different parts of a buffer. This could be useful in editing
343 Bison input files, for instance, or other kinds of text
344 where one language is embedded in another language. See
345 http://www.loveshack.ukfsn.org/emacs/multi-mode.el and also
346 mmm-mode, as reference for approaches taken by others.
347
348 ** Arrange a way for an input method to return the first character
349 immediately, then replace it later. So that C-s a with
350 input method latin-1-postfix would immediately search for an a.
351
352 ** Give start-process the ability to direct standard-error
353 output to a different filter.
354
355 ** Make desktop.el save the "frame configuration" of Emacs (in some
356 useful sense).
357
358 ** Give desktop.el a feature to switch between different named
359 desktops.
360
361 ** Add a cpio mode, more or less like tar mode.
362
363 ** Save undo information in special temporary files, and reload it
364 when needed for undoing. This could extend undo capacity.
365
366 ** Change the Windows NT menu code
367 so that it handles the deep_p argument and avoids
368 regenerating the whole menu bar menu tree except
369 when the user tries to use the menubar.
370
371 This requires the RIT to forward the WM_INITMENU message to
372 the main thread, and not return from that message until the main
373 thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated
374 the whole menu bar. In the mean time, it should process other messages.
375
376 ** Get some major packages installed: W3 (development version needs
377 significant work), PSGML, _possibly_ Cedet and ECB.
378 http://lists.gnu.org/archive/html/emacs-devel/2007-05/msg01493.html
379 Check the assignments file for other packages which might go in and
380 have been missed.
381
382 ** Possibly install python-mode in place of python.el, or combine the two.
383 Someone needs to do the work of figuring out who all the non-trivial
384 python-mode.el contributors are and getting assignments.
385 http://lists.gnu.org/archive/html/emacs-devel/2008-02/msg02156.html
386 http://lists.gnu.org/archive/html/emacs-devel/2008-02/msg02201.html
387 http://lists.gnu.org/archive/html/emacs-devel/2008-02/msg02489.html
388 http://lists.gnu.org/archive/html/emacs-devel/2008-02/msg02234.html
389
390 ** Make keymaps a first-class Lisp object (this means a rewrite of
391 keymap.c). What should it do apart from being opaque ?
392 multiple inheritance ? faster where-is ? no more fix_submap_inheritance ?
393 what else ?
394
395 ** Provide real menus on ttys. The MS-DOS implementation can serve as
396 an example how to do part of this; see the XMenu* functions on msdos.c.
397
398 ** Implement popular parts of the rest of the CL functions as compiler
399 macros in cl-macs.
400
401 ** Make compiler warnings about functions that might be undefined at run time
402 smarter, so that they know which files are required by the file being
403 compiled and don't warn about functions defined in them.
404
405 ** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA,
406 but it's a valuable feature worth making more general.
407
408 ** Provide MIME support for Rmail using the Gnus MIME library. [Maybe
409 not now feasible, given Gnus maintenance decisions. fx looked at
410 this and can say where some of the problems are.]
411
412 ** Eliminate the storm of warnings concerning char/unsigned char
413 mismatches that we get with GCC 4.x and proprietary compilers on
414 various systems. They make it difficult to spot the important
415 warnings.
416
417 ** Fix anything necessary to use `long long' EMACS_INTs with GCC.
418
419 ** Split out parts of lisp.h and generate Makefile dependencies
420 automatically.
421
422 ** Update the FAQ.
423
424 ** Allow auto-compression-mode to use zlib calls if zlib is available.
425 [It's required for PNG, so may be linked anyhow.]
426
427 ** Add a --pristine startup flag which does -q --no-site-file plus
428 ignoring X resources (Doze equivalents?) and most of the
429 environment. What should not be ignored needs consideration.
430 [Do the existing -Q and -D cover this, or is more needed?]
431
432 ** Improve the GC (generational, incremental). (We may be able to use
433 the Boehm collector.) [See the Boehm-GC branch in CVS for work on
434 this.]
435
436 ** Check what hooks would help Emacspeak -- see the defadvising in W3.
437
438 ** Add definitions for symbol properties, for documentation purposes.
439
440 ** Add horizontal scroll bars.
441
442 ** Provide an optional feature which computes a scroll bar slider's
443 size and its position from lines instead of characters.
444
445 ** Allow unknown image types to be rendered via an external program
446 converting them to, say, PBM (in the same way as PostScript?). [does
447 doc-view.el do this, or could it be extended to do this?]
448
449 ** Allow displaying an X window from an external program in a buffer,
450 e.g. to render graphics from Java applets. [gerd and/or wmperry
451 thought this was feasible.]
452
453 ** Allow images (not just text) in the margin to be mouse-sensitive.
454 (Requires recursing through display properties). Provide some way
455 to simulate mouse-clicks on marginal text without a mouse.
456
457 ** Implement Lisp functions to determine properly whether a character
458 is displayable (particularly needed in XFree 4, sigh). Use it to
459 define useful glyphs that may be displayed as images or unicodes
460 (with ASCIIfied fallback via latin1-disp). Examples include
461 box-drawing graphics in Custom buffers, W3 rules and tables, and
462 tree displays generally, mode-line mail indicator. [See work done
463 already for Emacs 23 and consult fx.]
464
465 ** Do something to make rms happy with fx's dynamic loading, and use it
466 to implement things like auto-loaded buffer parsers and database
467 access in cases which need more than Lisp.
468
469 ** Extend ps-print to deal with multiple font sizes, images, and extra
470 encodings.
471
472 ** Provide portable undumping using mmap (per gerd design).
473
474 ** Make byte-compile avoid binding an expanded defsubst's args
475 when the body only calls primitives.
476
477 ** Use the XIE X extension, if available, for image display.
478
479 ** Make monochrome images display using the foreground and background
480 colors of the applicable faces.
481
482 ** Make `format-time-string' preserve text properties like `format'.
483
484 ** Optionally make the cursor a little thinner at the end of a line
485 or the end of the buffer.
486
487 ** Port the conservative stack marking code of Emacs' garbage collector
488 to more systems, so that we can completely get rid of GCPROs. Note
489 that Boehm garbage collector provides this.
490
491 ** Reorder defcustom's in each package so that the more important
492 options come first in the Customize buffers. This could be done by
493 either rearranging the file (since options are shown in the order
494 they appear in the *.el files), or by adding a few :set-after
495 attributes.
496
497 ** Maybe document the features of libraries missing from the manual (or
498 ancillary manuals, including the Lisp manual in some cases).
499 This is not worth doing for all of these packages and we need not
500 aim for completeness, but some may be worth documenting.
501
502 Here's a list which is probably not complete/correct: align, allout,
503 artist, ansi-color, array, battery, calculator, cdl, cmuscheme,
504 completion, cua, delim-col, dirtrack, double, echistory, elide-head,
505 easymenu, expand, flow-ctrl, format [format-alist],
506 generic/generic-x [various modes], kermit, log-edit, ledit
507 [obsolete?], makesum, midnight [other than in Kill Buffer node],
508 mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile,
509 snmp-mode [?], soundex [should be interactive?], strokes [start from
510 the web page], talk, thingatpt [interactive functions?], type-break,
511 vcursor, xscheme, zone-mode [?], mlconvert [?], iso-cvt, iso-swed,
512 swedish, feedmail [?], uce, bruce, gametree, meese, page-ext,
513 refbib, refer, scribe, sgml-mode, spell, texinfo, underline,
514 cmacexp, hideif, mantemp [obsolete?], pcomplete, assoc, xml,
515 cvs-status (should be described in PCL-CVS manual); other progmodes,
516 probably in separate manual.
517
518 ** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap
519 the XPMs so that the color versions work generally. (Requires care
520 with the color used for the transparent regions.)
521
522 ** Convenient access to the `values' variable. It would be nice to have an
523 interface that would show you the printed reps of the elements of the
524 list in a menu, let you select one of the values, and put it into some
525 other variable, without changing the value of `values'.
526
527 ** (Controlled by a flag) make open and close syntax match exactly,
528 i.e. `(' doesn't match `]'.
529
530 ** Specify parameter ID-FORMAT in all calls to `file-attributes' and
531 `directory-files-and-attributes' where attributes UID or GID are used.
532 Whenever possible, use value 'string.
533 When done, change meaning of default value from 'integer to 'string.
534 If value 'integer is used nowhere, remove the parameter ID-FORMAT from
535 the definition of `file-attributes' and `directory-files-and-attributes'
536 and from the calls.
537
538 ** Make language-info-alist customizable. Currently a user can customize
539 only the variable `current-language-environment'.
540
541 ** Improve language environment handling so that Emacs can fit
542 better to a users locale. Currently Emacs uses utf-8 language
543 environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale
544 are also put in utf-8 lang. env. In such a case, it is
545 better to use Japanese lang. env. but prefer utf-8 coding system.
546
547 ** Enhance locale handling: handle language, territory and charset
548 orthogonally and de-emphasize language environments. Use the locale
549 to set up more things, such as fontsets, the default Ispell
550 dictionary, diary format, calendar holidays and display, quoting
551 characters and phrase boundaries, sentence endings, collation for
552 sorting (at least for unicodes), HTTP Accept-language, patterns for
553 directory listings and compilation messages, yes-or-no replies,
554 common menu items when the toolkit supports it ... `locale-info'
555 needs extending for LC_COLLATE &c. [fx started on this.]
556
557 ** Eliminate the current restriction on header printing by ps-print.
558 Currently, a header can contain only single 1-byte charset in
559 addition to ASCII.
560
561 ** In ps-print, provide an user friendly interface to specify fonts.
562
563 ** Enhance word boundary detection for such a script that doesn't use
564 space at word boundary (e.g. Thai).
565
566 ** Implement interface programs with major Japanese conversion server
567 in lib-src so that they can be used from the input method
568 "japanese". Currently, most Japanese users are using external
569 packages (e.g. tamago, anthy) or an input method via XIM.
570
571 ** Let LEIM handle the Mode_switch key like XIM does (i.e. a toggle like C-\
572 but which can also be used as a modifier).
573
574 ** Improve Help buffers: Change the face of previously visited links (like
575 Info, but also with regard to namespace), and give the value of
576 lisp expressions, e.g auto-mode-alist, the right face.
577
578 ** Possibly make `list-holidays' eval items in the calendar-holidays variable.
579 See thread
580 <http://lists.gnu.org/archive/html/emacs-devel/2006-02/msg01034.html>.
581 [rgm@gnu.org will look at this after 22.1]
582
583 ** Possibly make cal-dst use the system timezone database directly.
584 See thread
585 <http://lists.gnu.org/archive/html/emacs-pretest-bug/2006-11/msg00060.html>
586
587 ** Possibly add a "close" button to the modeline.
588 The idea is to add an "X" of some kind, that when clicked deletes
589 the window associated with that modeline.
590 http://lists.gnu.org/archive/html/emacs-devel/2007-09/msg02416.html
591
592 * Internal changes
593
594 ** Cleanup all the GC_ mark bit stuff -- there is no longer any distinction
595 since the mark bit is no longer stored in the Lisp_Object itself.
596
597 ** Refine the `predicate' arg to read-file-name.
598 Currently, it mixes up the predicate to apply when doing completion and the
599 one to use when terminating the selection.
600
601 ** Merge ibuffer.el and buff-menu.el.
602 More specifically do what's needed to make ibuffer.el the default,
603 or just an extension of buff-menu.el.
604
605 ** Use pcomplete by default in shell-mode.
606 This means to make it behave (by default) more like the current code.
607 Use it also for read-shell-command, M-x compile, ...
608
609 ** Merge sendmail.el and messages.el.
610 Probably not a complete merge, but at least arrange for messages.el to be
611 a derived mode of sendmail.el. Or arrange for messages.el to be split
612 into a small core and "the rest" so that we use less resources as long as
613 we stick to the features provided in sendmail.el.
614
615 ** Replace gmalloc.c with the modified Doug Lea code from the current
616 GNU libc so that the special mmapping of buffers can be removed --
617 that apparently loses under Solaris, at least. [fx has mostly done
618 this.]
619
620 ** Rewrite make-docfile to be clean and maintainable.
621
622 ** Add an inferior-comint-minor-mode to capture the common set of operations
623 offered by major modes that offer an associated inferior
624 comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic.
625 For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode,
626 haskell-mode, tuareg-mode, ...
627
628 ** Make SYNC_INPUT the default. [true since 2008-03-11]
629 All loops using immediate_quit need to be checked to ensure that
630 C-g can interrupt them, in case of an infinite loop. Once we
631 switch to using SYNC_INPUT, we can remove the BLOCK_INPUTs in the
632 allocation functions (allocate_string etc.) without worrying about
633 data munging.
634
635 ** Add "link" button class
636 Add a standard button-class named "link", and make all other link-like
637 button classes inherit from it. Set the default face of the "link" button
638 class to the standard "link" face.
639
640 * Other known bugs:
641
642 ** `make-frame' forgets unhandled parameters, at least for X11 frames.
643
644 ** a two-char comment-starter whose two chars are symbol constituents will
645 not be noticed if it appears within a word.
646
647 ** Fix unexelf.c to handle the .data.rel and .data.rel.local
648 sections made by GCC 3.4 on IRIX.
