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. | |

15 | * Simple tasks. These don't require much emacs knowledge, they are |
16 | suitable for anyone from beginners to experts. | |
17 | ||
bfb906ac DN |
18 | ** Convert modes that use view-mode to be derived from special-mode instead. |
19 | ||
9fe219e3 DN |
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 | ||
c884b4d7 | 24 | ** Major modes should have a menu entry. Examples of modes that do |
bfb906ac | 25 | not have one at the moment and probably should: text-mode, inferior-lisp-mode. |
c884b4d7 | 26 | |
479be3f4 | 27 | ** Check if all items on the mode-line have a suitable tooltip for all modes. |
c884b4d7 | 28 | |
4e0ace23 DN |
29 | ** edebug and debugger-mode should have a toolbar. |
30 | It can use the same icons as gud. | |
31 | ||
c884b4d7 DN |
32 | ** Check what minor modes don't use define-minor-mode and convert them |
33 | to use it. | |
34 | ||
6d095958 GM |
35 | ** Convert all defvars with leading `*' in the doc-strings into defcustoms |
36 | of appropriate :type and :group. | |
37 | ||
ba1c68de | 38 | * Small but important fixes needed in existing features: |
a9c1a157 | 39 | |
cc48343f RS |
40 | ** Flymake's customization mechanism needs to be both simpler (fewer |
41 | levels of indirection) and better documented, so it is easier to | |
42 | understand. I find it quite hard to figure out what compilation | |
43 | command it will use. | |
44 | ||
45 | I suggest totally rewriting that part of Flymake, using the simplest | |
46 | mechanism that sufficies for the specific needs. That will be easy | |
47 | for users to customize. | |
48 | ||
600e5c79 | 49 | ** Make "emacs --daemon" start emacs without showing any frame. |
f1d45b83 DN |
50 | Use emacsclient later to open frames. |
51 | ||
600e5c79 DN |
52 | ** Make it possible to reliably turn on minor modes using "mode:" in the local |
53 | variables section. | |
f1d45b83 | 54 | |
37202eec SM |
55 | ** "Options -> Save Options" should save the font set via "Set Font/Fontset" |
56 | I.e. mouse-set-font should use customize-face. | |
57 | ||
0989e765 SM |
58 | ** Compute the list of active keymaps *after* reading the first event. |
59 | ||
046ece71 KS |
60 | ** Distribute a bar cursor of width > 1 evenly between the two glyphs |
61 | on each side of the bar (what to do at the edges?). | |
62 | ||
d322eb9b RS |
63 | ** buffer-offer-save should be a permanent local. |
64 | ||
125fbe81 | 65 | ** revert-buffer should eliminate overlays and the mark. |
045744c6 MR |
66 | For related problems consult the thread starting with |
67 | http://lists.gnu.org/archive/html/emacs-devel/2005-11/msg01346.html | |
125fbe81 | 68 | |
f98abf6d RS |
69 | ** erase-buffer should perhaps disregard read-only properties of text. |
70 | ||
30c56b97 LT |
71 | ** Make occur correctly handle matches that span more than one line, |
72 | as well as overlapping matches. | |
73 | ||
d3a403e5 | 74 | ** Fix the kill/yank treatment of invisible text. At the moment, |
b9e6b498 | 75 | invisible text is placed in the kill-ring, so that the contents of |
2345130a SM |
76 | the ring may not correspond to the text as displayed to the user. |
77 | It ought to be possible to omit text which is invisible (due to a | |
b9e6b498 GM |
78 | text-property, overlay, or selective display) from the kill-ring. |
79 | ||
6f771c32 RS |
80 | ** Change the way define-minor-mode handles autoloading. |
81 | It should not generate :require. Or :require in defcustom | |
82 | should not be recorded in the user's custom-set-variables call. | |
83 | ||
af09dd78 RS |
84 | ** Feature to change cursor shape when Emacs is idle (for more than |
85 | a specified time). | |
86 | ||
4e07258f RS |
87 | ** The buttons at the top of a custom buffer should not omit |
88 | variables whose values are currently hidden. | |
89 | ||
ec0cf966 RS |
90 | ** Clean up the variables in browse-url. Perhaps use a shell command string to |
91 | specify the browser instead of the mushrooming set of functions. | |
92 | See also ESR's proposal for a BROWSER environment variable | |
93 | <URL:http://www.catb.org/~esr/BROWSER/browse-url.patch>. | |
94 | ||
528b6abc RS |
95 | ** Enhance scroll-bar to handle tall line (similar to line-move). |
96 | ||
97 | ** Make occur handle multi-line matches cleanly with context. | |
98 | ||
f98abf6d RS |
99 | ** In Custom buffers, put the option that turns a mode on or off first, |
100 | using a heuristic of some kind? | |
101 | ||
102 | ** Define recompute-arg and recompute-arg-if for fix_command to use. | |
103 | See rms message of 11 Dec 05. | |
104 | ||
7c14546c JD |
105 | ** Height returned by frame-parameter ... and height given to |
106 | make-frame does not mean the same thing. The former includes menu and | |
107 | tool bar lines, the latter don't. frame-parameter should return height | |
108 | without menu and tool bar lines. | |
109 | ||
f98abf6d RS |
110 | ** In Emacs Info, examples of using Customize should be clickable |
111 | and they should create Custom buffers. | |
112 | ||
321e4870 RS |
113 | ** The toolbar should show keyboard equivalents in its tooltips. |
114 | ||
74561a26 RS |
115 | ** Add function to redraw the tool bar. |
116 | ||
a9b6d67e RS |
117 | ** M-! M-n should fetch the buffer-file-name as the default. |
118 | ||
5a893bff RS |
119 | ** Redesign the load-history data structure so it can cope better |
120 | with evaluating definitions of the same function from different files, | |
121 | recording which file the latest definition came from. | |
046ece71 | 122 | |
4b4d11cc RS |
123 | ** make back_comment use syntax-ppss or equivalent. |
124 | ||
67ccd6cb GM |
125 | ** Consider improving src/sysdep.c's search for a fqdn. |
126 | http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00782.html | |
127 | ||
128 | ** Find a proper fix for rcirc multiline nick adding. | |
129 | http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00684.html | |
211fb124 | 130 | |
94172215 EZ |
131 | ** Implement `network-interface-list' and `network-interface-info' |
132 | on MS-Windows. Hint: the information is present in the Registry, | |
133 | under the keys | |
134 | HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Linkage\ | |
135 | and | |
136 | HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<device>\ | |
137 | where <device> is the network device found under the first key. | |
138 | ||
4af1faa3 GM |
139 | ** Check for any included packages that define obsolete bug-reporting commands. |
140 | Change them to use report-emacs-bug. | |
141 | ||
7a00b900 NR |
142 | ** Allow fringe indicators to display a tooltip (provide a help-echo property?) |
143 | ||
d73803e6 CY |
144 | ** Add a defcustom that supplies a function to name numeric backup files, |
145 | like make-backup-file-name-function for non-numeric backup files. | |
146 | ||
b1a345ee MR |
147 | ** `dired-mode' should specify the semantics of `buffer-modified-p' for |
148 | dired buffers and DTRT WRT `auto-revert-mode'. | |
149 | ||
ba1c68de | 150 | * Important features: |
a9c1a157 | 151 | |
cc48343f RS |
152 | ** Having tabs above a window to switch buffers in it. |
153 | ||
154 | ** "Perspectives" are named persistent window configurations. We have | |
155 | had the window configuration mechanism in GNU Emacs since the | |
156 | beginning but we have never developed a good user interface to take | |
157 | advantage of them. Eclipse's user interface seems to be good. | |
158 | ||
159 | Perspectives work well even if you do the equivalent of C-x 4 C-f | |
160 | because of the distinction between view windows vs file windows. In | |
161 | Emacs this is more or less the "dedicated window" feature, but we have | |
162 | never really made it work for this. | |
163 | ||
164 | Perspectives also need to interact with the tabs. | |
165 | ||
166 | ** Imenu could be extended into a file-structure browsing mechanism | |
167 | using code like that of customize-groups. | |
168 | ||
169 | ** Display something in the margin on lines that have compilation | |
170 | errors. | |
171 | ||
172 | ** Compilation error navigation bar, parallel to the scroll bar, | |
173 | indicating where in the buffer there are compilation errors. | |
174 | Perhaps we could arrange to display these error indications on top | |
175 | of the scroll bar itself. That depends on to what extent toolkit | |
176 | scroll bars are extensible. | |
177 | ||
ba1c68de | 178 | ** Provide user-friendly ways to list all available font families, |
321e4870 RS |
179 | list fonts, display a font as a sample, etc. [fx is looking at |
180 | multilingual font selection for the Unicode branch of Emacs.] | |
5e101746 | 181 | |
3aa7c28e RS |
182 | ** Provide a convenient way to select a color with the mouse. |
183 | ||
09d04fb3 | 184 | ** Rewrite the face code to be simpler, clearer and faster. |
5e101746 | 185 | |
ba1c68de | 186 | ** Program Enriched mode to read and save in RTF. [Is there actually a |
c51b37fd | 187 | decent single definition of RTF? Maybe see info at |
1b2105d9 EZ |
188 | http://latex2rtf.sourceforge.net/.] This task seems to be addressed |
189 | by http://savannah.nongnu.org/projects/emacs-rtf/, which is still in | |
190 | very early stages. | |
6165b6e3 | 191 | |
ba1c68de | 192 | ** Implement something better than the current Refill mode. This |
a9c1a157 RS |
193 | probably needs some primitive support. |
194 | ||
ba6be78d | 195 | ** Add a command to make a "Local Variables" section in the current buffer |
07ff1e4b RS |
196 | and/or add a variable to the list. |
197 | ||
ba1c68de | 198 | ** Implement primitive and higher-level functions to allow filling |
a9c1a157 RS |
199 | properly with variable-pitch faces. |
200 | ||
ba1c68de | 201 | ** Implement a smoother vertical scroll facility, one that allows |
d3a403e5 SM |
202 | C-v to scroll through a tall image. The primitive operations |
203 | posn-at-point and posn-at-x-y should now make it doable in elisp. | |
a9c1a157 | 204 | |
6ca1c497 RS |
205 | ** Implement intelligent search/replace, going beyond query-replace |
206 | (see http://graphics.csail.mit.edu/~rcm/chi04.pdf). | |
207 | ||
ba1c68de SM |
208 | ** Implement other text formatting properties. |
209 | *** Footnotes that can appear either in place or at the end of the page. | |
210 | *** text property that says "don't break line in middle of this". | |
6165b6e3 EZ |
211 | Don't break the line between two characters that have the |
212 | same value of this property. | |
ba1c68de | 213 | *** Discretionary hyphens that are not visible when they are at end of line. |
6165b6e3 | 214 | |
ec0cf966 RS |
215 | ** Internationalize Emacs's messages. |
216 | ||
4a7499a9 RS |
217 | ** Set up a facility to save backtraces when errors happen during |
218 | specified filters, specified timers, and specified hooks. | |
219 | ||
49322539 RS |
220 | ** Install mmc@maruska.dyndns.org's no-flicker change. |
221 | ||
07ff1e4b RS |
222 | ** Add a "current vertical pixel level" value that goes with point, |
223 | so that motion commands can also move through tall images. | |
224 | This value would be to point as window-vscroll is to window-start. | |
225 | ||
ec0cf966 RS |
226 | ** Address internationalization of symbols names essentially |
227 | as documentation, e.g. in command names and Custom. | |
a9c1a157 | 228 | |
ba1c68de | 229 | ** Make the Lucid menu widget display multilingual text. [This |
bf6394a6 DL |
230 | probably needs to be done from actual Emacs buffers, either directly |
231 | in the menu or by rendering in an unmapped window and copying the | |
f677a3a3 SM |
232 | pixels. The current code assumes a specific locale; that isn't good |
233 | enough even if X can render the arbitrary text] [The gtk | |
7bea57c9 DL |
234 | port now displays multilingual text in menus, but only insofar as |
235 | Emacs can encode it as utf-8 and gtk can display the result.] | |
f677a3a3 SM |
236 | Maybe making Lucid menus work like Gtk's (i.e. just force utf-8) is good |
237 | enough now that Emacs can encode most chars into utf-8. | |
a9c1a157 | 238 | |
ba1c68de | 239 | ** Remove the limitation that window and frame widths and heights can |
a9c1a157 RS |
240 | be only full columns/lines. |
241 | ||
ba1c68de SM |
242 | * Other features we would like: |
243 | ||
22f9eb9e CY |
244 | ** Make longlines-mode wrap lines based on screen position instead |
245 | of character position, so that variable-width fonts can be handled | |
246 | properly. | |
247 | ||
c3bb6fdb SM |
248 | ** Allow frames(terminals) created by emacsclient to inherit their environment |
249 | from the emacsclient process. | |
a37288ad SM |
250 | ** Remove the default toggling behavior of minor modes when called from elisp |
251 | rather than interactively. This a trivial one-liner in easy-mode.el. | |
0de301ed | 252 | |
a53e64cc SM |
253 | ** Create a category of errors called `user-error' for errors which are |
254 | typically due to pilot errors and should thus be in debug-ignored-errors. | |
255 | ||
39eadb4a RS |
256 | ** Give Tar mode all the features of Archive mode. |
257 | ||
9b8453da RS |
258 | ** Create a category of errors called `process-error' |
259 | for some or all errors associated with using subprocesses. | |
260 | ||
51f74c37 RS |
261 | ** Maybe reinterpret `parse-error' as a category of errors |
262 | and put some other errors under it. | |
263 | ||
1a500a73 | 264 | ** A function to tell you the argument pattern of functions. |
1b2105d9 | 265 | See `function-arity' in http://www.loveshack.ukfsn.org/emacs/fx-misc.el. |
1a500a73 RS |
266 | |
267 | ** Make byte-compile warn when a doc string is too wide. | |
268 | ||
9f4ba075 CY |
269 | ** Make byte-optimization warnings issue accurate line numbers. |
270 | ||
f95a20e7 RS |
271 | ** A function to check for customizable options that have been |
272 | set but not saved, and ask the user whether to save them. | |
273 | This could go in kill-emacs-query-functions, to remind people | |
274 | to save their changes. If the user says yes, show them | |
275 | in a Custom buffer using customize-customized. | |
276 | ||
8c9676fb DK |
277 | ** Record the sxhash of the default value for customized variables |
278 | and notify the user (maybe by adding a menu item or toolbar button, | |
279 | as the detection can occur during autoload time) when the default | |
280 | changes (meaning that new versions of the Lisp source with a changed | |
281 | default value got installed) and offer ediff on the respective | |
282 | customization buffers. | |
283 | ||
e0402468 | 284 | ** Emacs Lisp mode could put an overlay on the defun for every |
8c9676fb DK |
285 | function that has advice. The overlay could have `after-text' like |
286 | " [Function has advice]". It might look like (defun foo [Function | |
287 | has advice] (x y) The overlay could also be a button that you could | |
288 | use to view the advice. | |
e0402468 | 289 | |
17e55b2a RS |
290 | ** Add a function to get the insertion-type of the markers in an overlay. |
291 | ||
9c9c88db SM |
292 | ** ange-ftp |
293 | *** understand sftp | |
1b2105d9 EZ |
294 | This is hard to make work because sftp doesn't print status |
295 | messages. | |
296 | ||
9c9c88db SM |
297 | *** Use MLS for ange-ftp-insert-directory if a list of files is specified. |
298 | ||
ba1c68de SM |
299 | ** Ability to map a key, including all modified-combinations. |
300 | E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up | |
301 | M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 -> | |
302 | H-S-C-M-s-double-wheel-up, ... | |
a9c1a157 | 303 | |
ba1c68de SM |
304 | ** Beefed-up syntax-tables. |
305 | *** recognize multi-character syntactic entities like `begin' and `end'. | |
306 | *** nested string-delimiters (for Postscript's (foo(bar)baz) strings). | |
307 | *** support for infix operators (with precedence). | |
308 | *** support for the $ (paired delimiter) in parse-partial-sexp. | |
309 | *** support for hook-chars whose effect on the parsing-state is specified | |
310 | by elisp code. Thus a char could both close a string and open a comment | |
311 | at the same time and do it in a context-sensitive way. | |
312 | *** ability to add mode-specific data to the partial-parse-state. | |
313 | ||
2d1ef312 RS |
314 | ** Add a way to convert a keyboard macro to equivalent Lisp code. |
315 | ||
ba1c68de | 316 | ** Have a command suggestion help system that recognizes patterns |
a9c1a157 RS |
317 | of commands which could be replaced with a simpler common command. |
318 | It should not make more than one suggestion per 10 minutes. | |
6165b6e3 | 319 | |
ba1c68de | 320 | ** Add a way to define input methods by computing them (when first used) |
30a2aafd RS |
321 | from other input methods. Then redefine C-x 8 to use a |
322 | user-selected input method, with the default being the union of | |
323 | latin-1-prefix and latin-1-postfix. | |
324 | ||
a7abe867 | 325 | ** Switch the Windows port to using Unicode keyboard input (maybe). |
2fa4f835 EZ |
326 | Based on http://msdn2.microsoft.com/en-us/library/ms633586.aspx, |
327 | this boils down to (1) calling RegisterClassW function to register | |
328 | Emacs windows, and (2) modifying ALL system messages to use Unicode. | |
329 | In particular, WM_CHAR messages, which result from keyboard input, | |
a7abe867 | 330 | will then come in encoded in UTF-16. |
2fa4f835 EZ |
331 | |
332 | One advantage of switching to Unicode is to toss encoded-kbd usage, | |
333 | which will solve the problem with binding non-ASCII keys with | |
334 | modifiers. | |
335 | ||
a7abe867 RS |
336 | Problem: using this on Windows 9x/ME requires installing the |
337 | Microsoft Layer for Unicode (MSLU), which might not implement all | |
338 | the required functionality that is available built-in on Windows XP | |
339 | and later. We should not make this change if it would pressure | |
340 | users of unauthorized copies of older versions of Windows to | |
341 | downgrade to versions that require activation. | |
342 | ||
ba1c68de | 343 | ** Implement a clean way to use different major modes for |
06382b71 RS |
344 | different parts of a buffer. This could be useful in editing |
345 | Bison input files, for instance, or other kinds of text | |
1b2105d9 EZ |
346 | where one language is embedded in another language. See |
347 | http://www.loveshack.ukfsn.org/emacs/multi-mode.el and also | |
8b5e9361 | 348 | mmm-mode, as reference for approaches taken by others. |
a933dad1 | 349 | |
b76781cd RS |
350 | ** Arrange a way for an input method to return the first character |
351 | immediately, then replace it later. So that C-s a with | |
352 | input method latin-1-postfix would immediately search for an a. | |
a933dad1 | 353 | |
ba1c68de | 354 | ** Give start-process the ability to direct standard-error |
a933dad1 DL |
355 | output to a different filter. |
356 | ||
ba1c68de | 357 | ** Make desktop.el save the "frame configuration" of Emacs (in some |
a933dad1 DL |
358 | useful sense). |
359 | ||
ba1c68de | 360 | ** Give desktop.el a feature to switch between different named |
8ba148c7 RS |
361 | desktops. |
362 | ||
ba1c68de | 363 | ** Replace finder.el with something that generates an Info file |
e39fc314 DL |
364 | which gives the same information through a menu structure. [Dave |
365 | Love started on this.] | |
a933dad1 | 366 | |
10bb671b RS |
367 | ** Add a cpio mode, more or less like tar mode. |
368 | ||
06382b71 RS |
369 | ** Save undo information in special temporary files, and reload it |
370 | when needed for undoing. This could extend undo capacity. | |
a933dad1 | 371 | |
ba1c68de | 372 | ** Change the Windows NT menu code |
a933dad1 DL |
373 | so that it handles the deep_p argument and avoids |
374 | regenerating the whole menu bar menu tree except | |
375 | when the user tries to use the menubar. | |
376 | ||
377 | This requires the RIT to forward the WM_INITMENU message to | |
378 | the main thread, and not return from that message until the main | |
0245b3ef | 379 | thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated |
a933dad1 | 380 | the whole menu bar. In the mean time, it should process other messages. |
d054101f | 381 | |
ba1c68de | 382 | ** Get some major packages installed: W3 (development version needs |
93a759ba | 383 | significant work), PSGML, _possibly_ Cedet and ECB. |
590394eb GM |
384 | http://lists.gnu.org/archive/html/emacs-devel/2007-05/msg01493.html |
385 | Check the assignments file for other packages which might go in and | |
386 | have been missed. | |
387 | ||
7d6f3b3a GM |
388 | ** Possibly install python-mode in place of python.el, or combine the two. |
389 | Someone needs to do the work of figuring out who all the non-trivial | |
390 | python-mode.el contributors are and getting assignments. | |

395 | ||
ba1c68de | 396 | ** Make keymaps a first-class Lisp object (this means a rewrite of |
5dd31b13 SM |
397 | keymap.c). What should it do apart from being opaque ? |
398 | multiple inheritance ? faster where-is ? no more fix_submap_inheritance ? | |
399 | what else ? | |
e39fc314 | 400 | |
ba1c68de | 401 | ** Provide real menus on ttys. The MS-DOS implementation can serve as |
2fa4f835 | 402 | an example how to do part of this; see the XMenu* functions on msdos.c. |
e39fc314 | 403 | |
ba1c68de | 404 | ** Implement popular parts of the rest of the CL functions as compiler |
e39fc314 DL |
405 | macros in cl-macs. |
406 | ||
261b01c6 RS |
407 | ** Make compiler warnings about functions that might be undefined at run time |
408 | smarter, so that they know which files are required by the file being | |
409 | compiled and don't warn about functions defined in them. | |
410 | ||
ba1c68de | 411 | ** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA, |
a52ce7f8 | 412 | but it's a valuable feature worth making more general. |
e39fc314 | 413 | |
ba1c68de | 414 | ** Provide MIME support for Rmail using the Gnus MIME library. [Maybe |
bf6394a6 DL |
415 | not now feasible, given Gnus maintenance decisions. fx looked at |
416 | this and can say where some of the problems are.] | |
e39fc314 | 417 | |
ba1c68de | 418 | ** Eliminate the storm of warnings concerning char/unsigned char |
1b2105d9 EZ |
419 | mismatches that we get with GCC 4.x and proprietary compilers on |
420 | various systems. They make it difficult to spot the important | |
421 | warnings. | |
e39fc314 | 422 | |
ba1c68de | 423 | ** Fix anything necessary to use `long long' EMACS_INTs with GCC. |
eaf67bae | 424 | |
ba1c68de | 425 | ** Split out parts of lisp.h and generate Makefile dependencies |
eaf67bae DL |
426 | automatically. |
427 | ||
ba1c68de | 428 | ** Update the FAQ. |
eaf67bae | 429 | |
ba1c68de | 430 | ** Allow auto-compression-mode to use zlib calls if zlib is available. |
b04f7626 | 431 | [It's required for PNG, so may be linked anyhow.] |
1265b539 | 432 | |
ba1c68de | 433 | ** Add a --pristine startup flag which does -q --no-site-file plus |
1265b539 DL |
434 | ignoring X resources (Doze equivalents?) and most of the |
435 | environment. What should not be ignored needs consideration. | |
590394eb | 436 | [Do the existing -Q and -D cover this, or is more needed?] |
1265b539 | 437 | |
ba1c68de | 438 | ** Improve the GC (generational, incremental). (We may be able to use |
7bea57c9 DL |
439 | the Boehm collector.) [See the Boehm-GC branch in CVS for work on |
440 | this.] | |
19cc91fb | 441 | |
ba1c68de | 442 | ** Check what hooks would help Emacspeak -- see the defadvising in W3. |
e2849090 | 443 | |
a5bd14d3 RS |
444 | ** Add definitions for symbol properties, for documentation purposes. |
445 | ||
ba1c68de | 446 | ** Add horizontal scroll bars. |
00a18b59 | 447 | |
ba1c68de | 448 | ** Provide an optional feature which computes a scroll bar slider's |
e4ded23c | 449 | size and its position from lines instead of characters. |
c0460c17 | 450 | |
ba1c68de | 451 | ** Allow unknown image types to be rendered via an external program |
590394eb GM |
452 | converting them to, say, PBM (in the same way as PostScript?). [does |
453 | doc-view.el do this, or could it be extended to do this?] | |
d1c3f6b6 | 454 | |
ba1c68de | 455 | ** Allow displaying an X window from an external program in a buffer, |
d1c3f6b6 RS |
456 | e.g. to render graphics from Java applets. [gerd and/or wmperry |
457 | thought this was feasible.] | |
458 | ||
ba1c68de | 459 | ** Allow images (not just text) in the margin to be mouse-sensitive. |
d1c3f6b6 RS |
460 | (Requires recursing through display properties). Provide some way |
461 | to simulate mouse-clicks on marginal text without a mouse. | |
462 | ||
ba1c68de | 463 | ** Implement Lisp functions to determine properly whether a character |
d1c3f6b6 RS |
464 | is displayable (particularly needed in XFree 4, sigh). Use it to |
465 | define useful glyphs that may be displayed as images or unicodes | |
466 | (with ASCIIfied fallback via latin1-disp). Examples include | |
467 | box-drawing graphics in Custom buffers, W3 rules and tables, and | |
468 | tree displays generally, mode-line mail indicator. [See work done | |
8589dc17 | 469 | already for Emacs 23 and consult fx.] |
d1c3f6b6 | 470 | |
ba1c68de | 471 | ** Do something to make rms happy with fx's dynamic loading, and use it |
d1c3f6b6 RS |
472 | to implement things like auto-loaded buffer parsers and database |
473 | access in cases which need more than Lisp. | |
474 | ||
ba1c68de | 475 | ** Extend ps-print to deal with multiple font sizes, images, and extra |
d1c3f6b6 RS |
476 | encodings. |
477 | ||
ba1c68de | 478 | ** Provide portable undumping using mmap (per gerd design). |
d1c3f6b6 | 479 | |
48b194fd | 480 | ** Make byte-compile avoid binding an expanded defsubst's args |
8b5e9361 | 481 | when the body only calls primitives. |
48b194fd | 482 | |
ba1c68de | 483 | ** Use the XIE X extension, if available, for image display. |
e641b454 | 484 | |
ba1c68de | 485 | ** Make monochrome images display using the foreground and background |
51fe665a RS |
486 | colors of the applicable faces. |
487 | ||
ec68482b RS |
488 | ** Make `format-time-string' preserve text properties like `format'. |
489 | ||
fda12b27 RS |
490 | ** Optionally make the cursor a little thinner at the end of a line |
491 | or the end of the buffer. | |
492 | ||
ba1c68de | 493 | ** Port the conservative stack marking code of Emacs' garbage collector |
1b2105d9 EZ |
494 | to more systems, so that we can completely get rid of GCPROs. Note |
495 | that Boehm garbage collector provides this. | |
5e101746 | 496 | |
ba1c68de | 497 | ** Reorder defcustom's in each package so that the more important |
5005a9c0 EZ |
498 | options come first in the Customize buffers. This could be done by |
499 | either rearranging the file (since options are shown in the order | |
500 | they appear in the *.el files), or by adding a few :set-after | |
501 | attributes. | |
502 | ||
ba1c68de | 503 | ** Maybe document the features of libraries missing from the manual (or |
5e101746 RS |
504 | ancillary manuals, including the Lisp manual in some cases). |
505 | This is not worth doing for all of these packages and we need not | |
506 | aim for completeness, but some may be worth documenting. | |
507 | ||
508 | Here's a list which is probably not complete/correct: align, allout, | |
509 | artist, ansi-color, array, battery, calculator, cdl, cmuscheme, | |
657c5358 | 510 | completion, cua, delim-col, dirtrack, double, echistory, elide-head, |
5e101746 RS |
511 | easymenu, expand, flow-ctrl, format [format-alist], |
512 | generic/generic-x [various modes], kermit, log-edit, ledit | |
513 | [obsolete?], makesum, midnight [other than in Kill Buffer node], | |
514 | mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile, | |
515 | snmp-mode [?], soundex [should be interactive?], strokes [start from | |
516 | the web page], talk, thingatpt [interactive functions?], type-break, | |
517 | vcursor, xscheme, zone-mode [?], mlconvert [?], iso-cvt, iso-swed, | |
518 | swedish, feedmail [?], uce, bruce, gametree, meese, page-ext, | |
519 | refbib, refer, scribe, sgml-mode, spell, texinfo, underline, | |
520 | cmacexp, hideif, mantemp [obsolete?], pcomplete, assoc, xml, | |
521 | cvs-status (should be described in PCL-CVS manual); other progmodes, | |
522 | probably in separate manual. | |
758830ba | 523 | |
ba1c68de | 524 | ** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap |
6772c8e1 GM |
525 | the XPMs so that the color versions work generally. (Requires care |
526 | with the color used for the transparent regions.) | |
bf6394a6 | 527 | |
ba1c68de | 528 | ** Convenient access to the `values' variable. It would be nice to have an |
758830ba JB |
529 | interface that would show you the printed reps of the elements of the |
530 | list in a menu, let you select one of the values, and put it into some | |
531 | other variable, without changing the value of `values'. | |
bf6394a6 | 532 | |
ba1c68de | 533 | ** (Controlled by a flag) make open and close syntax match exactly, |
c51b37fd DL |
534 | i.e. `(' doesn't match `]'. |
535 | ||
ba1c68de | 536 | ** Specify parameter ID-FORMAT in all calls to `file-attributes' and |
9ac8c83b LH |
537 | `directory-files-and-attributes' where attributes UID or GID are used. |
538 | Whenever possible, use value 'string. | |
539 | When done, change meaning of default value from 'integer to 'string. | |
540 | If value 'integer is used nowhere, remove the parameter ID-FORMAT from | |
541 | the definition of `file-attributes' and `directory-files-and-attributes' | |
542 | and from the calls. | |
543 | ||
cf4c9271 KH |
544 | ** Make language-info-alist customizable. Currently a user can customize |
545 | only the variable `current-language-environment'. | |
546 | ||
547 | ** Improve language environment handling so that Emacs can fit | |
548 | better to a users locale. Currently Emacs uses utf-8 language | |
549 | environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale | |
550 | are also put in utf-8 lang. env. In such a case, it is | |
551 | better to use Japanese lang. env. but prefer utf-8 coding system. | |
1f724d55 | 552 | |
321e4870 RS |
553 | ** Enhance locale handling: handle language, territory and charset |
554 | orthogonally and de-emphasize language environments. Use the locale | |
555 | to set up more things, such as fontsets, the default Ispell | |
556 | dictionary, diary format, calendar holidays and display, quoting | |
557 | characters and phrase boundaries, sentence endings, collation for | |
558 | sorting (at least for unicodes), HTTP Accept-language, patterns for | |
559 | directory listings and compilation messages, yes-or-no replies, | |
560 | common menu items when the toolkit supports it ... `locale-info' | |
561 | needs extending for LC_COLLATE &c. [fx started on this.] | |
562 | ||
1f724d55 KH |
563 | ** Eliminate the current restriction on header printing by ps-print. |
564 | Currently, a header can contain only single 1-byte charset in | |
565 | addition to ASCII. | |
566 | ||
567 | ** In ps-print, provide an user friendly interface to specify fonts. | |
568 | ||
1f724d55 KH |
569 | ** Enhance word boundary detection for such a script that doesn't use |
570 | space at word boundary (e.g. Thai). | |
571 | ||
cf4c9271 KH |
572 | ** Implement interface programs with major Japanese conversion server |
573 | in lib-src so that they can be used from the input method | |
574 | "japanese". Currently, most Japanese users are using external | |
575 | packages (e.g. tamago, anthy) or an input method via XIM. | |
1f724d55 | 576 | |
a53e64cc | 577 | ** Let LEIM handle the Mode_switch key like XIM does (i.e. a toggle like C-\ |
8b5e9361 | 578 | but which can also be used as a modifier). |
a53e64cc | 579 | |
d59e3c42 | 580 | ** Improve Help buffers: Change the face of previously visited links (like |
8b5e9361 GM |
581 | Info, but also with regard to namespace), and give the value of |
582 | lisp expressions, e.g auto-mode-alist, the right face. | |
d59e3c42 | 583 | |
5a473319 GM |
584 | ** Possibly make `list-holidays' eval items in the calendar-holidays variable. |
585 | See thread | |
586 | <http://lists.gnu.org/archive/html/emacs-devel/2006-02/msg01034.html>. | |
587 | [rgm@gnu.org will look at this after 22.1] | |
588 | ||
9e21382c GM |
589 | ** Possibly make cal-dst use the system timezone database directly. |
590 | See thread | |
591 | <http://lists.gnu.org/archive/html/emacs-pretest-bug/2006-11/msg00060.html> | |
592 | ||
590394eb GM |
593 | ** Possibly add a "close" button to the modeline. |
594 | The idea is to add an "X" of some kind, that when clicked deletes | |
595 | the window associated with that modeline. | |

ba1c68de SM |
598 | * Internal changes |
599 | ||
41a023e3 | 600 | ** Cleanup all the GC_ mark bit stuff -- there is no longer any distinction |
dcbccc4d CY |
601 | since the mark bit is no longer stored in the Lisp_Object itself. |
602 | ||
12cdb1c1 SM |
603 | ** Refine the `predicate' arg to read-file-name. |
604 | Currently, it mixes up the predicate to apply when doing completion and the | |
605 | one to use when terminating the selection. | |
606 | ||
1d919365 SM |
607 | ** Merge ibuffer.el and buff-menu.el. |
608 | More specifically do what's needed to make ibuffer.el the default, | |
609 | or just an extension of buff-menu.el. | |
610 | ||
611 | ** Use pcomplete by default in shell-mode. | |
612 | This means to make it behave (by default) more like the current code. | |
613 | Use it also for read-shell-command, M-x compile, ... | |
614 | ||
615 | ** Merge sendmail.el and messages.el. | |
616 | Probably not a complete merge, but at least arrange for messages.el to be | |
617 | a derived mode of sendmail.el. Or arrange for messages.el to be split | |
618 | into a small core and "the rest" so that we use less resources as long as | |
619 | we stick to the features provided in sendmail.el. | |
045744c6 | 620 | |
ba1c68de | 621 | ** Replace gmalloc.c with the modified Doug Lea code from the current |
1d919365 SM |
622 | GNU libc so that the special mmapping of buffers can be removed -- |
623 | that apparently loses under Solaris, at least. [fx has mostly done | |
624 | this.] | |
ba1c68de SM |
625 | |
626 | ** Rewrite make-docfile to be clean and maintainable. | |
627 | ||
628 | ** Add an inferior-comint-minor-mode to capture the common set of operations | |
629 | offered by major modes that offer an associated inferior | |
d3a403e5 SM |
630 | comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic. |
631 | For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode, | |
632 | haskell-mode, tuareg-mode, ... | |
ba1c68de | 633 | |
8b5e9361 | 634 | ** Make SYNC_INPUT the default. [true since 2008-03-11] |
7cef6228 CY |
635 | All loops using immediate_quit need to be checked to ensure that |
636 | C-g can interrupt them, in case of an infinite loop. Once we | |
637 | switch to using SYNC_INPUT, we can remove the BLOCK_INPUTs in the | |
638 | allocation functions (allocate_string etc.) without worrying about | |
639 | data munging. | |
640 | ||
f57dad5a MB |
641 | ** Add "link" button class |
642 | Add a standard button-class named "link", and make all other link-like | |
643 | button classes inherit from it. Set the default face of the "link" button | |
644 | class to the standard "link" face. | |
645 | ||
2345130a SM |
646 | * Other known bugs: |
647 | ||
c3bb6fdb | 648 | ** `make-frame' forgets unhandled parameters, at least for X11 frames. |
48b8e4a0 | 649 | |
2345130a SM |
650 | ** a two-char comment-starter whose two chars are symbol constituents will |
651 | not be noticed if it appears within a word. | |
652 | ||
07ff1e4b RS |
653 | ** Fix unexelf.c to handle the .data.rel and .data.rel.local |
654 | sections made by GCC 3.4 on IRIX. | |
