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 | |
7bea57c9 | 11 | it best. Since Emacs is an FSF-copyrighted package, please be |
2255d5b4 RS |
12 | prepared to sign legal papers to transfer the copyright on your work |
13 | to the FSF. | |
14 | ||
ba1c68de | 15 | * Small but important fixes needed in existing features: |
a9c1a157 | 16 | |
600e5c79 | 17 | ** Make "emacs --daemon" start emacs without showing any frame. |
f1d45b83 DN |
18 | Use emacsclient later to open frames. |
19 | ||
600e5c79 DN |
20 | ** Make it possible to reliably turn on minor modes using "mode:" in the local |
21 | variables section. | |
f1d45b83 | 22 | |
37202eec SM |
23 | ** "Options -> Save Options" should save the font set via "Set Font/Fontset" |
24 | I.e. mouse-set-font should use customize-face. | |
25 | ||
0989e765 SM |
26 | ** Compute the list of active keymaps *after* reading the first event. |
27 | ||
046ece71 KS |
28 | ** Distribute a bar cursor of width > 1 evenly between the two glyphs |
29 | on each side of the bar (what to do at the edges?). | |
30 | ||
e008f665 DN |
31 | ** Make vc-checkin avoid reverting the buffer if has not changed after |
32 | the checkin. Comparing (md5 BUFFER) to (md5 FILE) should be enough. | |
33 | ||
d322eb9b RS |
34 | ** buffer-offer-save should be a permanent local. |
35 | ||
2a29c409 | 36 | ** revert-buffer should eliminate overlays and the mark. |
045744c6 MR |
37 | For related problems consult the thread starting with |
38 | http://lists.gnu.org/archive/html/emacs-devel/2005-11/msg01346.html | |
2a29c409 | 39 | |
f98abf6d RS |
40 | ** erase-buffer should perhaps disregard read-only properties of text. |
41 | ||
30c56b97 LT |
42 | ** Make occur correctly handle matches that span more than one line, |
43 | as well as overlapping matches. | |
44 | ||
d3a403e5 | 45 | ** Fix the kill/yank treatment of invisible text. At the moment, |
b9e6b498 | 46 | invisible text is placed in the kill-ring, so that the contents of |
2345130a SM |
47 | the ring may not correspond to the text as displayed to the user. |
48 | It ought to be possible to omit text which is invisible (due to a | |
b9e6b498 GM |
49 | text-property, overlay, or selective display) from the kill-ring. |
50 | ||
6f771c32 RS |
51 | ** Change the way define-minor-mode handles autoloading. |
52 | It should not generate :require. Or :require in defcustom | |
53 | should not be recorded in the user's custom-set-variables call. | |
54 | ||
af09dd78 RS |
55 | ** Feature to change cursor shape when Emacs is idle (for more than |
56 | a specified time). | |
57 | ||
4e07258f RS |
58 | ** The buttons at the top of a custom buffer should not omit |
59 | variables whose values are currently hidden. | |
60 | ||
ec0cf966 RS |
61 | ** Clean up the variables in browse-url. Perhaps use a shell command string to |
62 | specify the browser instead of the mushrooming set of functions. | |
63 | See also ESR's proposal for a BROWSER environment variable | |
64 | <URL:http://www.catb.org/~esr/BROWSER/browse-url.patch>. | |
65 | ||
528b6abc RS |
66 | ** Enhance scroll-bar to handle tall line (similar to line-move). |
67 | ||
68 | ** Make occur handle multi-line matches cleanly with context. | |
69 | ||
f98abf6d RS |
70 | ** In Custom buffers, put the option that turns a mode on or off first, |
71 | using a heuristic of some kind? | |
72 | ||
73 | ** Define recompute-arg and recompute-arg-if for fix_command to use. | |
74 | See rms message of 11 Dec 05. | |
75 | ||
7c14546c JD |
76 | ** Height returned by frame-parameter ... and height given to |
77 | make-frame does not mean the same thing. The former includes menu and | |
78 | tool bar lines, the latter don't. frame-parameter should return height | |
79 | without menu and tool bar lines. | |
80 | ||
f98abf6d RS |
81 | ** In Emacs Info, examples of using Customize should be clickable |
82 | and they should create Custom buffers. | |
83 | ||
321e4870 RS |
84 | ** The toolbar should show keyboard equivalents in its tooltips. |
85 | ||
74561a26 RS |
86 | ** Add function to redraw the tool bar. |
87 | ||
a9b6d67e RS |
88 | ** M-! M-n should fetch the buffer-file-name as the default. |
89 | ||
5a893bff RS |
90 | ** Redesign the load-history data structure so it can cope better |
91 | with evaluating definitions of the same function from different files, | |
92 | recording which file the latest definition came from. | |
046ece71 | 93 | |
4b4d11cc RS |
94 | ** make back_comment use syntax-ppss or equivalent. |
95 | ||
67ccd6cb GM |
96 | ** Consider improving src/sysdep.c's search for a fqdn. |
97 | http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00782.html | |
98 | ||
99 | ** Find a proper fix for rcirc multiline nick adding. | |
100 | http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00684.html | |
211fb124 | 101 | |
94172215 EZ |
102 | ** Implement `network-interface-list' and `network-interface-info' |
103 | on MS-Windows. Hint: the information is present in the Registry, | |
104 | under the keys | |
105 | HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Linkage\ | |
106 | and | |
107 | HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<device>\ | |
108 | where <device> is the network device found under the first key. | |
109 | ||
4af1faa3 GM |
110 | ** Check for any included packages that define obsolete bug-reporting commands. |
111 | Change them to use report-emacs-bug. | |
112 | ||
ba1c68de | 113 | * Important features: |
a9c1a157 | 114 | |
ba1c68de | 115 | ** Provide user-friendly ways to list all available font families, |
321e4870 RS |
116 | list fonts, display a font as a sample, etc. [fx is looking at |
117 | multilingual font selection for the Unicode branch of Emacs.] | |
5e101746 | 118 | |
3aa7c28e RS |
119 | ** Provide a convenient way to select a color with the mouse. |
120 | ||
09d04fb3 RS |
121 | ** Rewrite the face code to be simpler, clearer and faster. |
122 | ||
ba1c68de | 123 | ** Program Enriched mode to read and save in RTF. [Is there actually a |
c51b37fd | 124 | decent single definition of RTF? Maybe see info at |
1b2105d9 EZ |
125 | http://latex2rtf.sourceforge.net/.] This task seems to be addressed |
126 | by http://savannah.nongnu.org/projects/emacs-rtf/, which is still in | |
127 | very early stages. | |
6165b6e3 | 128 | |
ba1c68de | 129 | ** Implement something better than the current Refill mode. This |
a9c1a157 RS |
130 | probably needs some primitive support. |
131 | ||
ba6be78d | 132 | ** Add a command to make a "Local Variables" section in the current buffer |
07ff1e4b RS |
133 | and/or add a variable to the list. |
134 | ||
ba1c68de | 135 | ** Implement primitive and higher-level functions to allow filling |
a9c1a157 RS |
136 | properly with variable-pitch faces. |
137 | ||
ba1c68de | 138 | ** Implement a smoother vertical scroll facility, one that allows |
d3a403e5 SM |
139 | C-v to scroll through a tall image. The primitive operations |
140 | posn-at-point and posn-at-x-y should now make it doable in elisp. | |
a9c1a157 | 141 | |
6ca1c497 RS |
142 | ** Implement intelligent search/replace, going beyond query-replace |
143 | (see http://graphics.csail.mit.edu/~rcm/chi04.pdf). | |
144 | ||
ba1c68de SM |
145 | ** Implement other text formatting properties. |
146 | *** Footnotes that can appear either in place or at the end of the page. | |
147 | *** text property that says "don't break line in middle of this". | |
6165b6e3 EZ |
148 | Don't break the line between two characters that have the |
149 | same value of this property. | |
ba1c68de | 150 | *** Discretionary hyphens that are not visible when they are at end of line. |
6165b6e3 | 151 | |
ec0cf966 RS |
152 | ** Internationalize Emacs's messages. |
153 | ||
4a7499a9 RS |
154 | ** Set up a facility to save backtraces when errors happen during |
155 | specified filters, specified timers, and specified hooks. | |
156 | ||
49322539 RS |
157 | ** Install mmc@maruska.dyndns.org's no-flicker change. |
158 | ||
07ff1e4b RS |
159 | ** Add a "current vertical pixel level" value that goes with point, |
160 | so that motion commands can also move through tall images. | |
161 | This value would be to point as window-vscroll is to window-start. | |
162 | ||
ec0cf966 RS |
163 | ** Address internationalization of symbols names essentially |
164 | as documentation, e.g. in command names and Custom. | |
a9c1a157 | 165 | |
ba1c68de | 166 | ** Make the Lucid menu widget display multilingual text. [This |
bf6394a6 DL |
167 | probably needs to be done from actual Emacs buffers, either directly |
168 | in the menu or by rendering in an unmapped window and copying the | |
f677a3a3 SM |
169 | pixels. The current code assumes a specific locale; that isn't good |
170 | enough even if X can render the arbitrary text] [The gtk | |
7bea57c9 DL |
171 | port now displays multilingual text in menus, but only insofar as |
172 | Emacs can encode it as utf-8 and gtk can display the result.] | |
f677a3a3 SM |
173 | Maybe making Lucid menus work like Gtk's (i.e. just force utf-8) is good |
174 | enough now that Emacs can encode most chars into utf-8. | |
a9c1a157 | 175 | |
ba1c68de | 176 | ** Remove the limitation that window and frame widths and heights can |
a9c1a157 RS |
177 | be only full columns/lines. |
178 | ||
ba1c68de SM |
179 | * Other features we would like: |
180 | ||
c3bb6fdb SM |
181 | ** Allow frames(terminals) created by emacsclient to inherit their environment |
182 | from the emacsclient process. | |
a37288ad SM |
183 | ** Remove the default toggling behavior of minor modes when called from elisp |
184 | rather than interactively. This a trivial one-liner in easy-mode.el. | |
0de301ed | 185 | |
a53e64cc SM |
186 | ** Create a category of errors called `user-error' for errors which are |
187 | typically due to pilot errors and should thus be in debug-ignored-errors. | |
188 | ||
39eadb4a RS |
189 | ** Give Tar mode all the features of Archive mode. |
190 | ||
9b8453da RS |
191 | ** Create a category of errors called `process-error' |
192 | for some or all errors associated with using subprocesses. | |
193 | ||
51f74c37 RS |
194 | ** Maybe reinterpret `parse-error' as a category of errors |
195 | and put some other errors under it. | |
196 | ||
1a500a73 | 197 | ** A function to tell you the argument pattern of functions. |
1b2105d9 | 198 | See `function-arity' in http://www.loveshack.ukfsn.org/emacs/fx-misc.el. |
1a500a73 RS |
199 | |
200 | ** Make byte-compile warn when a doc string is too wide. | |
201 | ||
9f4ba075 CY |
202 | ** Make byte-optimization warnings issue accurate line numbers. |
203 | ||
f95a20e7 RS |
204 | ** A function to check for customizable options that have been |
205 | set but not saved, and ask the user whether to save them. | |
206 | This could go in kill-emacs-query-functions, to remind people | |
207 | to save their changes. If the user says yes, show them | |
208 | in a Custom buffer using customize-customized. | |
209 | ||
8c9676fb DK |
210 | ** Record the sxhash of the default value for customized variables |
211 | and notify the user (maybe by adding a menu item or toolbar button, | |
212 | as the detection can occur during autoload time) when the default | |
213 | changes (meaning that new versions of the Lisp source with a changed | |
214 | default value got installed) and offer ediff on the respective | |
215 | customization buffers. | |
216 | ||
e0402468 | 217 | ** Emacs Lisp mode could put an overlay on the defun for every |
8c9676fb DK |
218 | function that has advice. The overlay could have `after-text' like |
219 | " [Function has advice]". It might look like (defun foo [Function | |
220 | has advice] (x y) The overlay could also be a button that you could | |
221 | use to view the advice. | |
e0402468 | 222 | |
17e55b2a RS |
223 | ** Add a function to get the insertion-type of the markers in an overlay. |
224 | ||
9c9c88db SM |
225 | ** ange-ftp |
226 | *** understand sftp | |
1b2105d9 EZ |
227 | This is hard to make work because sftp doesn't print status |
228 | messages. | |
229 | ||
9c9c88db SM |
230 | *** Use MLS for ange-ftp-insert-directory if a list of files is specified. |
231 | ||
ba1c68de SM |
232 | ** Ability to map a key, including all modified-combinations. |
233 | E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up | |
234 | M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 -> | |
235 | H-S-C-M-s-double-wheel-up, ... | |
a9c1a157 | 236 | |
ba1c68de SM |
237 | ** Beefed-up syntax-tables. |
238 | *** recognize multi-character syntactic entities like `begin' and `end'. | |
239 | *** nested string-delimiters (for Postscript's (foo(bar)baz) strings). | |
240 | *** support for infix operators (with precedence). | |
241 | *** support for the $ (paired delimiter) in parse-partial-sexp. | |
242 | *** support for hook-chars whose effect on the parsing-state is specified | |
243 | by elisp code. Thus a char could both close a string and open a comment | |
244 | at the same time and do it in a context-sensitive way. | |
245 | *** ability to add mode-specific data to the partial-parse-state. | |
246 | ||
2d1ef312 RS |
247 | ** Add a way to convert a keyboard macro to equivalent Lisp code. |
248 | ||
ba1c68de | 249 | ** Have a command suggestion help system that recognizes patterns |
a9c1a157 RS |
250 | of commands which could be replaced with a simpler common command. |
251 | It should not make more than one suggestion per 10 minutes. | |
6165b6e3 | 252 | |
ba1c68de | 253 | ** Add a way to define input methods by computing them (when first used) |
30a2aafd RS |
254 | from other input methods. Then redefine C-x 8 to use a |
255 | user-selected input method, with the default being the union of | |
256 | latin-1-prefix and latin-1-postfix. | |
257 | ||
a7abe867 | 258 | ** Switch the Windows port to using Unicode keyboard input (maybe). |
2fa4f835 EZ |
259 | Based on http://msdn2.microsoft.com/en-us/library/ms633586.aspx, |
260 | this boils down to (1) calling RegisterClassW function to register | |
261 | Emacs windows, and (2) modifying ALL system messages to use Unicode. | |
262 | In particular, WM_CHAR messages, which result from keyboard input, | |
a7abe867 | 263 | will then come in encoded in UTF-16. |
2fa4f835 EZ |
264 | |
265 | One advantage of switching to Unicode is to toss encoded-kbd usage, | |
266 | which will solve the problem with binding non-ASCII keys with | |
267 | modifiers. | |
268 | ||
a7abe867 RS |
269 | Problem: using this on Windows 9x/ME requires installing the |
270 | Microsoft Layer for Unicode (MSLU), which might not implement all | |
271 | the required functionality that is available built-in on Windows XP | |
272 | and later. We should not make this change if it would pressure | |
273 | users of unauthorized copies of older versions of Windows to | |
274 | downgrade to versions that require activation. | |
275 | ||
ba1c68de | 276 | ** Implement a clean way to use different major modes for |
06382b71 RS |
277 | different parts of a buffer. This could be useful in editing |
278 | Bison input files, for instance, or other kinds of text | |
1b2105d9 EZ |
279 | where one language is embedded in another language. See |
280 | http://www.loveshack.ukfsn.org/emacs/multi-mode.el and also | |
281 | mmm-mode, as reference for approaches took by others. | |
a933dad1 | 282 | |
b76781cd RS |
283 | ** Arrange a way for an input method to return the first character |
284 | immediately, then replace it later. So that C-s a with | |
285 | input method latin-1-postfix would immediately search for an a. | |
286 | ||
ba1c68de | 287 | ** Give start-process the ability to direct standard-error |
a933dad1 DL |
288 | output to a different filter. |
289 | ||
ba1c68de | 290 | ** Make desktop.el save the "frame configuration" of Emacs (in some |
a933dad1 DL |
291 | useful sense). |
292 | ||
ba1c68de | 293 | ** Give desktop.el a feature to switch between different named |
8ba148c7 RS |
294 | desktops. |
295 | ||
ba1c68de | 296 | ** Replace finder.el with something that generates an Info file |
e39fc314 DL |
297 | which gives the same information through a menu structure. [Dave |
298 | Love started on this.] | |
a933dad1 | 299 | |
10bb671b RS |
300 | ** Add a cpio mode, more or less like tar mode. |
301 | ||
ba1c68de | 302 | ** Implement a variant of uncompress.el or jka-compr.el that works with |
2794f7ab DL |
303 | GNU Privacy Guard for encryption. [Code exists but isn't assigned. |
304 | See the Gnus development sources for assigned code concerning GPG | |
1b2105d9 EZ |
305 | use with mail, which is probably a good start.] See also |
306 | http://www.loveshack.ukfsn.org/emacs/auto-crypt.tgz. | |
a933dad1 | 307 | |
06382b71 RS |
308 | ** Save undo information in special temporary files, and reload it |
309 | when needed for undoing. This could extend undo capacity. | |
a933dad1 | 310 | |
ba1c68de | 311 | ** Change the Windows NT menu code |
a933dad1 DL |
312 | so that it handles the deep_p argument and avoids |
313 | regenerating the whole menu bar menu tree except | |
314 | when the user tries to use the menubar. | |
315 | ||
316 | This requires the RIT to forward the WM_INITMENU message to | |
317 | the main thread, and not return from that message until the main | |
0245b3ef | 318 | thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated |
a933dad1 | 319 | the whole menu bar. In the mean time, it should process other messages. |
d054101f | 320 | |
ba1c68de | 321 | ** Get some major packages installed: W3 (development version needs |
93a759ba | 322 | significant work), PSGML, _possibly_ Cedet and ECB. |
590394eb GM |
323 | http://lists.gnu.org/archive/html/emacs-devel/2007-05/msg01493.html |
324 | Check the assignments file for other packages which might go in and | |
325 | have been missed. | |
326 | ||
ba1c68de | 327 | ** Make keymaps a first-class Lisp object (this means a rewrite of |
5dd31b13 SM |
328 | keymap.c). What should it do apart from being opaque ? |
329 | multiple inheritance ? faster where-is ? no more fix_submap_inheritance ? | |
330 | what else ? | |
e39fc314 | 331 | |
ba1c68de | 332 | ** Provide real menus on ttys. The MS-DOS implementation can serve as |
2fa4f835 | 333 | an example how to do part of this; see the XMenu* functions on msdos.c. |
e39fc314 | 334 | |
ba1c68de | 335 | ** Implement popular parts of the rest of the CL functions as compiler |
e39fc314 DL |
336 | macros in cl-macs. |
337 | ||
261b01c6 RS |
338 | ** Make compiler warnings about functions that might be undefined at run time |
339 | smarter, so that they know which files are required by the file being | |
340 | compiled and don't warn about functions defined in them. | |
341 | ||
ba1c68de | 342 | ** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA, |
a52ce7f8 | 343 | but it's a valuable feature worth making more general. |
e39fc314 | 344 | |
ba1c68de | 345 | ** Provide MIME support for Rmail using the Gnus MIME library. [Maybe |
bf6394a6 DL |
346 | not now feasible, given Gnus maintenance decisions. fx looked at |
347 | this and can say where some of the problems are.] | |
e39fc314 | 348 | |
ba1c68de | 349 | ** Eliminate the storm of warnings concerning char/unsigned char |
1b2105d9 EZ |
350 | mismatches that we get with GCC 4.x and proprietary compilers on |
351 | various systems. They make it difficult to spot the important | |
352 | warnings. | |
e39fc314 | 353 | |
ba1c68de | 354 | ** Fix anything necessary to use `long long' EMACS_INTs with GCC. |
eaf67bae | 355 | |
ba1c68de | 356 | ** Split out parts of lisp.h and generate Makefile dependencies |
eaf67bae DL |
357 | automatically. |
358 | ||
ba1c68de | 359 | ** Update the FAQ. |
eaf67bae | 360 | |
ba1c68de | 361 | ** Allow auto-compression-mode to use zlib calls if zlib is available. |
b04f7626 | 362 | [It's required for PNG, so may be linked anyhow.] |
1265b539 | 363 | |
ba1c68de | 364 | ** Add a --pristine startup flag which does -q --no-site-file plus |
1265b539 DL |
365 | ignoring X resources (Doze equivalents?) and most of the |
366 | environment. What should not be ignored needs consideration. | |
590394eb | 367 | [Do the existing -Q and -D cover this, or is more needed?] |
1265b539 | 368 | |
ba1c68de | 369 | ** Improve the GC (generational, incremental). (We may be able to use |
7bea57c9 DL |
370 | the Boehm collector.) [See the Boehm-GC branch in CVS for work on |
371 | this.] | |
19cc91fb | 372 | |
ba1c68de | 373 | ** Check what hooks would help Emacspeak -- see the defadvising in W3. |
e2849090 | 374 | |
a5bd14d3 RS |
375 | ** Add definitions for symbol properties, for documentation purposes. |
376 | ||
ba1c68de | 377 | ** Add horizontal scroll bars. |
00a18b59 | 378 | |
ba1c68de | 379 | ** Provide an optional feature which computes a scroll bar slider's |
e4ded23c | 380 | size and its position from lines instead of characters. |
c0460c17 | 381 | |
ba1c68de | 382 | ** Allow unknown image types to be rendered via an external program |
590394eb GM |
383 | converting them to, say, PBM (in the same way as PostScript?). [does |
384 | doc-view.el do this, or could it be extended to do this?] | |
d1c3f6b6 | 385 | |
ba1c68de | 386 | ** Allow displaying an X window from an external program in a buffer, |
d1c3f6b6 RS |
387 | e.g. to render graphics from Java applets. [gerd and/or wmperry |
388 | thought this was feasible.] | |
389 | ||
ba1c68de | 390 | ** Allow images (not just text) in the margin to be mouse-sensitive. |
d1c3f6b6 RS |
391 | (Requires recursing through display properties). Provide some way |
392 | to simulate mouse-clicks on marginal text without a mouse. | |
393 | ||
ba1c68de | 394 | ** Implement Lisp functions to determine properly whether a character |
d1c3f6b6 RS |
395 | is displayable (particularly needed in XFree 4, sigh). Use it to |
396 | define useful glyphs that may be displayed as images or unicodes | |
397 | (with ASCIIfied fallback via latin1-disp). Examples include | |
398 | box-drawing graphics in Custom buffers, W3 rules and tables, and | |
399 | tree displays generally, mode-line mail indicator. [See work done | |
400 | already for Emacs 22 and consult fx.] | |
401 | ||
ba1c68de | 402 | ** Do something to make rms happy with fx's dynamic loading, and use it |
d1c3f6b6 RS |
403 | to implement things like auto-loaded buffer parsers and database |
404 | access in cases which need more than Lisp. | |
405 | ||
ba1c68de | 406 | ** Extend ps-print to deal with multiple font sizes, images, and extra |
d1c3f6b6 RS |
407 | encodings. |
408 | ||
ba1c68de | 409 | ** Provide portable undumping using mmap (per gerd design). |
d1c3f6b6 | 410 | |
48b194fd RS |
411 | ** Make byte-compile avoid binding an expanded defsubst's args |
412 | when the body only calls primitives. | |
413 | ||
ba1c68de | 414 | ** Use the XIE X extension, if available, for image display. |
e641b454 | 415 | |
ba1c68de | 416 | ** Make monochrome images display using the foreground and background |
51fe665a RS |
417 | colors of the applicable faces. |
418 | ||
d101bf56 RS |
419 | ** Face remapping. |
420 | ||
ec68482b RS |
421 | ** Make `format-time-string' preserve text properties like `format'. |
422 | ||
fda12b27 RS |
423 | ** Optionally make the cursor a little thinner at the end of a line |
424 | or the end of the buffer. | |
425 | ||
ba1c68de | 426 | ** Add support for rendering antialiased text, probably using |
2a573e69 | 427 | XRender/Freetype. |
c5020b5b | 428 | |
ba1c68de | 429 | ** Port the conservative stack marking code of Emacs' garbage collector |
1b2105d9 EZ |
430 | to more systems, so that we can completely get rid of GCPROs. Note |
431 | that Boehm garbage collector provides this. | |
5e101746 | 432 | |
ba1c68de | 433 | ** Reorder defcustom's in each package so that the more important |
5005a9c0 EZ |
434 | options come first in the Customize buffers. This could be done by |
435 | either rearranging the file (since options are shown in the order | |
436 | they appear in the *.el files), or by adding a few :set-after | |
437 | attributes. | |
438 | ||
ba1c68de | 439 | ** Maybe document the features of libraries missing from the manual (or |
5e101746 RS |
440 | ancillary manuals, including the Lisp manual in some cases). |
441 | This is not worth doing for all of these packages and we need not | |
442 | aim for completeness, but some may be worth documenting. | |
443 | ||
444 | Here's a list which is probably not complete/correct: align, allout, | |
445 | artist, ansi-color, array, battery, calculator, cdl, cmuscheme, | |
657c5358 | 446 | completion, cua, delim-col, dirtrack, double, echistory, elide-head, |
5e101746 RS |
447 | easymenu, expand, flow-ctrl, format [format-alist], |
448 | generic/generic-x [various modes], kermit, log-edit, ledit | |
449 | [obsolete?], makesum, midnight [other than in Kill Buffer node], | |
450 | mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile, | |
451 | snmp-mode [?], soundex [should be interactive?], strokes [start from | |
452 | the web page], talk, thingatpt [interactive functions?], type-break, | |
453 | vcursor, xscheme, zone-mode [?], mlconvert [?], iso-cvt, iso-swed, | |
454 | swedish, feedmail [?], uce, bruce, gametree, meese, page-ext, | |
455 | refbib, refer, scribe, sgml-mode, spell, texinfo, underline, | |
456 | cmacexp, hideif, mantemp [obsolete?], pcomplete, assoc, xml, | |
457 | cvs-status (should be described in PCL-CVS manual); other progmodes, | |
458 | probably in separate manual. | |
758830ba | 459 | |
ba1c68de | 460 | ** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap |
bf6394a6 DL |
461 | the XPMs so that the colour versions work generally. (Requires care |
462 | with the colour used for the transparent regions.) | |
463 | ||
ba1c68de | 464 | ** Convenient access to the `values' variable. It would be nice to have an |
758830ba JB |
465 | interface that would show you the printed reps of the elements of the |
466 | list in a menu, let you select one of the values, and put it into some | |
467 | other variable, without changing the value of `values'. | |
bf6394a6 | 468 | |
ba1c68de | 469 | ** (Controlled by a flag) make open and close syntax match exactly, |
c51b37fd DL |
470 | i.e. `(' doesn't match `]'. |
471 | ||
ba1c68de | 472 | ** Specify parameter ID-FORMAT in all calls to `file-attributes' and |
9ac8c83b LH |
473 | `directory-files-and-attributes' where attributes UID or GID are used. |
474 | Whenever possible, use value 'string. | |
475 | When done, change meaning of default value from 'integer to 'string. | |
476 | If value 'integer is used nowhere, remove the parameter ID-FORMAT from | |
477 | the definition of `file-attributes' and `directory-files-and-attributes' | |
478 | and from the calls. | |
479 | ||
81e4af5f EZ |
480 | ** Modify the emulation of `stat' for MS-Windows to support large files. |
481 | The current version uses the stock Windows definition of `struct | |
482 | stat', where the file's size is returned as a 32-bit integer. That | |
483 | overflows for files larger than 4GB. To fix, modify `stat' to use | |
484 | 64-bit size, and use a declaration of `struct stat' that supports | |
485 | such sizes. | |
486 | ||
cf4c9271 KH |
487 | ** Make language-info-alist customizable. Currently a user can customize |
488 | only the variable `current-language-environment'. | |
489 | ||
490 | ** Improve language environment handling so that Emacs can fit | |
491 | better to a users locale. Currently Emacs uses utf-8 language | |
492 | environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale | |
493 | are also put in utf-8 lang. env. In such a case, it is | |
494 | better to use Japanese lang. env. but prefer utf-8 coding system. | |
1f724d55 | 495 | |
321e4870 RS |
496 | ** Enhance locale handling: handle language, territory and charset |
497 | orthogonally and de-emphasize language environments. Use the locale | |
498 | to set up more things, such as fontsets, the default Ispell | |
499 | dictionary, diary format, calendar holidays and display, quoting | |
500 | characters and phrase boundaries, sentence endings, collation for | |
501 | sorting (at least for unicodes), HTTP Accept-language, patterns for | |
502 | directory listings and compilation messages, yes-or-no replies, | |
503 | common menu items when the toolkit supports it ... `locale-info' | |
504 | needs extending for LC_COLLATE &c. [fx started on this.] | |
505 | ||
1f724d55 KH |
506 | ** Eliminate the current restriction on header printing by ps-print. |
507 | Currently, a header can contain only single 1-byte charset in | |
508 | addition to ASCII. | |
509 | ||
510 | ** In ps-print, provide an user friendly interface to specify fonts. | |
511 | ||
512 | ** OpenType font support for various complex scripts (e.g. Devanagari). | |
513 | As X protocal doesn't provide a way to access OpenType Layout Tables | |
514 | in a OpenType font of a server side, we need a way to utilize local | |
515 | fonts (perhaps by directly using the Freetype library or indirectly | |
516 | via Xft library). | |
517 | ||
518 | ** Enhance word boundary detection for such a script that doesn't use | |
519 | space at word boundary (e.g. Thai). | |
520 | ||
cf4c9271 KH |
521 | ** Implement interface programs with major Japanese conversion server |
522 | in lib-src so that they can be used from the input method | |
523 | "japanese". Currently, most Japanese users are using external | |
524 | packages (e.g. tamago, anthy) or an input method via XIM. | |
1f724d55 | 525 | |
a53e64cc SM |
526 | ** Let LEIM handle the Mode_switch key like XIM does (i.e. a toggle like C-\ |
527 | but which can also be used as a modifier). | |
528 | ||
d59e3c42 NR |
529 | ** Improve Help buffers: Change the face of previously visited links (like |
530 | Info, but also with regard to namespace), add a forward button to make the | |
531 | Help buffer more browser like and gives the value of lisp expressions | |
532 | e.g auto-mode-alist, the right face. [nickrob@snap.net.nz has a patch | |
533 | for this for inclusion after 22.1]. | |
534 | ||
5a473319 GM |
535 | ** Possibly make `list-holidays' eval items in the calendar-holidays variable. |
536 | See thread | |
537 | <http://lists.gnu.org/archive/html/emacs-devel/2006-02/msg01034.html>. | |
538 | [rgm@gnu.org will look at this after 22.1] | |
539 | ||
9e21382c GM |
540 | ** Possibly make cal-dst use the system timezone database directly. |
541 | See thread | |

543 | ||
590394eb GM |
544 | ** Possibly add a "close" button to the modeline. |
545 | The idea is to add an "X" of some kind, that when clicked deletes | |
546 | the window associated with that modeline. | |

ba1c68de SM |
549 | * Internal changes |
550 | ||
41a023e3 | 551 | ** Cleanup all the GC_ mark bit stuff -- there is no longer any distinction |
dcbccc4d CY |
552 | since the mark bit is no longer stored in the Lisp_Object itself. |
553 | ||
12cdb1c1 SM |
554 | ** Refine the `predicate' arg to read-file-name. |
555 | Currently, it mixes up the predicate to apply when doing completion and the | |
556 | one to use when terminating the selection. | |
557 | ||
1d919365 SM |
558 | ** Merge ibuffer.el and buff-menu.el. |
559 | More specifically do what's needed to make ibuffer.el the default, | |
560 | or just an extension of buff-menu.el. | |
561 | ||
562 | ** Use pcomplete by default in shell-mode. | |
563 | This means to make it behave (by default) more like the current code. | |
564 | Use it also for read-shell-command, M-x compile, ... | |
565 | ||
566 | ** Merge sendmail.el and messages.el. | |
567 | Probably not a complete merge, but at least arrange for messages.el to be | |
568 | a derived mode of sendmail.el. Or arrange for messages.el to be split | |
569 | into a small core and "the rest" so that we use less resources as long as | |
570 | we stick to the features provided in sendmail.el. | |
045744c6 | 571 | |
ba1c68de | 572 | ** Replace gmalloc.c with the modified Doug Lea code from the current |
1d919365 SM |
573 | GNU libc so that the special mmapping of buffers can be removed -- |
574 | that apparently loses under Solaris, at least. [fx has mostly done | |
575 | this.] | |
ba1c68de SM |
576 | |
577 | ** Rewrite make-docfile to be clean and maintainable. | |
578 | ||
579 | ** Add an inferior-comint-minor-mode to capture the common set of operations | |
580 | offered by major modes that offer an associated inferior | |
d3a403e5 SM |
581 | comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic. |
582 | For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode, | |
583 | haskell-mode, tuareg-mode, ... | |
ba1c68de | 584 | |
7cef6228 CY |
585 | ** Make SYNC_INPUT the default. |
586 | All loops using immediate_quit need to be checked to ensure that | |
587 | C-g can interrupt them, in case of an infinite loop. Once we | |
588 | switch to using SYNC_INPUT, we can remove the BLOCK_INPUTs in the | |
589 | allocation functions (allocate_string etc.) without worrying about | |
590 | data munging. | |
591 | ||
f57dad5a MB |
592 | ** Add "link" button class |
593 | Add a standard button-class named "link", and make all other link-like | |
594 | button classes inherit from it. Set the default face of the "link" button | |
595 | class to the standard "link" face. | |
596 | ||
2345130a SM |
597 | * Other known bugs: |
598 | ||
c3bb6fdb | 599 | ** `make-frame' forgets unhandled parameters, at least for X11 frames. |
48b8e4a0 SM |
600 | ** The \\{...} keymap dump output does not correctly remove shadowed entries: |
601 | From: "Drew Adams" <drew.adams@oracle.com> | |

603 | (define-key minibuffer-local-map [(control ?=)] 'foo) | |
