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 | ||
9fe219e3 DN |
18 | ** make emacsclient accept -nw as a synonym to -t. |
19 | ||
20 | ** Replace some uses of the preprocessor code in Makefile.in with the equivalent autoconf. | |
21 | ||
c884b4d7 DN |
22 | ** Major modes should have a menu entry. Examples of modes that do |
23 | not have one at the moment and probably should: text-mode, | |
cea60091 | 24 | change-log-mode, texinfo-mode, inferior-lisp-mode. |
c884b4d7 | 25 | |
479be3f4 | 26 | ** Check if all items on the mode-line have a suitable tooltip for all modes. |
c884b4d7 | 27 | |
4e0ace23 DN |
28 | ** edebug and debugger-mode should have a toolbar. |
29 | It can use the same icons as gud. | |
30 | ||
c884b4d7 DN |
31 | ** Check what minor modes don't use define-minor-mode and convert them |
32 | to use it. | |
33 | ||
6d095958 GM |
34 | ** Convert all defvars with leading `*' in the doc-strings into defcustoms |
35 | of appropriate :type and :group. | |
36 | ||
ba1c68de | 37 | * Small but important fixes needed in existing features: |
a9c1a157 | 38 | |
cc48343f RS |
39 | ** Flymake's customization mechanism needs to be both simpler (fewer |
40 | levels of indirection) and better documented, so it is easier to | |
41 | understand. I find it quite hard to figure out what compilation | |
42 | command it will use. | |
43 | ||
44 | I suggest totally rewriting that part of Flymake, using the simplest | |
45 | mechanism that sufficies for the specific needs. That will be easy | |
46 | for users to customize. | |
47 | ||
600e5c79 | 48 | ** Make "emacs --daemon" start emacs without showing any frame. |
f1d45b83 DN |
49 | Use emacsclient later to open frames. |
50 | ||
600e5c79 DN |
51 | ** Make it possible to reliably turn on minor modes using "mode:" in the local |
52 | variables section. | |
f1d45b83 | 53 | |
37202eec SM |
54 | ** "Options -> Save Options" should save the font set via "Set Font/Fontset" |
55 | I.e. mouse-set-font should use customize-face. | |
56 | ||
0989e765 SM |
57 | ** Compute the list of active keymaps *after* reading the first event. |
58 | ||
046ece71 KS |
59 | ** Distribute a bar cursor of width > 1 evenly between the two glyphs |
60 | on each side of the bar (what to do at the edges?). | |
61 | ||
d322eb9b RS |
62 | ** buffer-offer-save should be a permanent local. |
63 | ||
125fbe81 | 64 | ** revert-buffer should eliminate overlays and the mark. |
045744c6 MR |
65 | For related problems consult the thread starting with |
66 | http://lists.gnu.org/archive/html/emacs-devel/2005-11/msg01346.html | |
125fbe81 | 67 | |
f98abf6d RS |
68 | ** erase-buffer should perhaps disregard read-only properties of text. |
69 | ||
30c56b97 LT |
70 | ** Make occur correctly handle matches that span more than one line, |
71 | as well as overlapping matches. | |
72 | ||
d3a403e5 | 73 | ** Fix the kill/yank treatment of invisible text. At the moment, |
b9e6b498 | 74 | invisible text is placed in the kill-ring, so that the contents of |
2345130a SM |
75 | the ring may not correspond to the text as displayed to the user. |
76 | It ought to be possible to omit text which is invisible (due to a | |
b9e6b498 GM |
77 | text-property, overlay, or selective display) from the kill-ring. |
78 | ||
6f771c32 RS |
79 | ** Change the way define-minor-mode handles autoloading. |
80 | It should not generate :require. Or :require in defcustom | |
81 | should not be recorded in the user's custom-set-variables call. | |
82 | ||
af09dd78 RS |
83 | ** Feature to change cursor shape when Emacs is idle (for more than |
84 | a specified time). | |
85 | ||
4e07258f RS |
86 | ** The buttons at the top of a custom buffer should not omit |
87 | variables whose values are currently hidden. | |
88 | ||
ec0cf966 RS |
89 | ** Clean up the variables in browse-url. Perhaps use a shell command string to |
90 | specify the browser instead of the mushrooming set of functions. | |
91 | See also ESR's proposal for a BROWSER environment variable | |
92 | <URL:http://www.catb.org/~esr/BROWSER/browse-url.patch>. | |
93 | ||
528b6abc RS |
94 | ** Enhance scroll-bar to handle tall line (similar to line-move). |
95 | ||
96 | ** Make occur handle multi-line matches cleanly with context. | |
97 | ||
f98abf6d RS |
98 | ** In Custom buffers, put the option that turns a mode on or off first, |
99 | using a heuristic of some kind? | |
100 | ||
101 | ** Define recompute-arg and recompute-arg-if for fix_command to use. | |
102 | See rms message of 11 Dec 05. | |
103 | ||
7c14546c JD |
104 | ** Height returned by frame-parameter ... and height given to |
105 | make-frame does not mean the same thing. The former includes menu and | |
106 | tool bar lines, the latter don't. frame-parameter should return height | |
107 | without menu and tool bar lines. | |
108 | ||
f98abf6d RS |
109 | ** In Emacs Info, examples of using Customize should be clickable |
110 | and they should create Custom buffers. | |
111 | ||
321e4870 RS |
112 | ** The toolbar should show keyboard equivalents in its tooltips. |
113 | ||
74561a26 RS |
114 | ** Add function to redraw the tool bar. |
115 | ||
a9b6d67e RS |
116 | ** M-! M-n should fetch the buffer-file-name as the default. |
117 | ||
5a893bff RS |
118 | ** Redesign the load-history data structure so it can cope better |
119 | with evaluating definitions of the same function from different files, | |
120 | recording which file the latest definition came from. | |
046ece71 | 121 | |
4b4d11cc RS |
122 | ** make back_comment use syntax-ppss or equivalent. |
123 | ||
67ccd6cb GM |
124 | ** Consider improving src/sysdep.c's search for a fqdn. |
125 | http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00782.html | |
126 | ||
127 | ** Find a proper fix for rcirc multiline nick adding. | |
128 | http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00684.html | |
211fb124 | 129 | |
94172215 EZ |
130 | ** Implement `network-interface-list' and `network-interface-info' |
131 | on MS-Windows. Hint: the information is present in the Registry, | |
132 | under the keys | |
133 | HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Linkage\ | |
134 | and | |
135 | HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<device>\ | |
136 | where <device> is the network device found under the first key. | |
137 | ||
4af1faa3 GM |
138 | ** Check for any included packages that define obsolete bug-reporting commands. |
139 | Change them to use report-emacs-bug. | |
140 | ||
7a00b900 NR |
141 | ** Allow fringe indicators to display a tooltip (provide a help-echo property?) |
142 | ||
d73803e6 CY |
143 | ** Add a defcustom that supplies a function to name numeric backup files, |
144 | like make-backup-file-name-function for non-numeric backup files. | |
145 | ||
ba1c68de | 146 | * Important features: |
a9c1a157 | 147 | |
cc48343f RS |
148 | ** Having tabs above a window to switch buffers in it. |
149 | ||
150 | ** "Perspectives" are named persistent window configurations. We have | |
151 | had the window configuration mechanism in GNU Emacs since the | |
152 | beginning but we have never developed a good user interface to take | |
153 | advantage of them. Eclipse's user interface seems to be good. | |
154 | ||
155 | Perspectives work well even if you do the equivalent of C-x 4 C-f | |
156 | because of the distinction between view windows vs file windows. In | |
157 | Emacs this is more or less the "dedicated window" feature, but we have | |
158 | never really made it work for this. | |
159 | ||
160 | Perspectives also need to interact with the tabs. | |
161 | ||
162 | ** Imenu could be extended into a file-structure browsing mechanism | |
163 | using code like that of customize-groups. | |
164 | ||
165 | ** Display something in the margin on lines that have compilation | |
166 | errors. | |
167 | ||
168 | ** Compilation error navigation bar, parallel to the scroll bar, | |
169 | indicating where in the buffer there are compilation errors. | |
170 | Perhaps we could arrange to display these error indications on top | |
171 | of the scroll bar itself. That depends on to what extent toolkit | |
172 | scroll bars are extensible. | |
173 | ||
ba1c68de | 174 | ** Provide user-friendly ways to list all available font families, |
321e4870 RS |
175 | list fonts, display a font as a sample, etc. [fx is looking at |
176 | multilingual font selection for the Unicode branch of Emacs.] | |
5e101746 | 177 | |
3aa7c28e RS |
178 | ** Provide a convenient way to select a color with the mouse. |
179 | ||
09d04fb3 | 180 | ** Rewrite the face code to be simpler, clearer and faster. |
5e101746 | 181 | |
ba1c68de | 182 | ** Program Enriched mode to read and save in RTF. [Is there actually a |
c51b37fd | 183 | decent single definition of RTF? Maybe see info at |
1b2105d9 EZ |
184 | http://latex2rtf.sourceforge.net/.] This task seems to be addressed |
185 | by http://savannah.nongnu.org/projects/emacs-rtf/, which is still in | |
186 | very early stages. | |
6165b6e3 | 187 | |
ba1c68de | 188 | ** Implement something better than the current Refill mode. This |
a9c1a157 RS |
189 | probably needs some primitive support. |
190 | ||
ba6be78d | 191 | ** Add a command to make a "Local Variables" section in the current buffer |
07ff1e4b RS |
192 | and/or add a variable to the list. |
193 | ||
ba1c68de | 194 | ** Implement primitive and higher-level functions to allow filling |
a9c1a157 RS |
195 | properly with variable-pitch faces. |
196 | ||
ba1c68de | 197 | ** Implement a smoother vertical scroll facility, one that allows |
d3a403e5 SM |
198 | C-v to scroll through a tall image. The primitive operations |
199 | posn-at-point and posn-at-x-y should now make it doable in elisp. | |
a9c1a157 | 200 | |
6ca1c497 RS |
201 | ** Implement intelligent search/replace, going beyond query-replace |
202 | (see http://graphics.csail.mit.edu/~rcm/chi04.pdf). | |
203 | ||
ba1c68de SM |
204 | ** Implement other text formatting properties. |
205 | *** Footnotes that can appear either in place or at the end of the page. | |
206 | *** text property that says "don't break line in middle of this". | |
6165b6e3 EZ |
207 | Don't break the line between two characters that have the |
208 | same value of this property. | |
ba1c68de | 209 | *** Discretionary hyphens that are not visible when they are at end of line. |
6165b6e3 | 210 | |
ec0cf966 RS |
211 | ** Internationalize Emacs's messages. |
212 | ||
4a7499a9 RS |
213 | ** Set up a facility to save backtraces when errors happen during |
214 | specified filters, specified timers, and specified hooks. | |
215 | ||
49322539 RS |
216 | ** Install mmc@maruska.dyndns.org's no-flicker change. |
217 | ||
07ff1e4b RS |
218 | ** Add a "current vertical pixel level" value that goes with point, |
219 | so that motion commands can also move through tall images. | |
220 | This value would be to point as window-vscroll is to window-start. | |
221 | ||
ec0cf966 RS |
222 | ** Address internationalization of symbols names essentially |
223 | as documentation, e.g. in command names and Custom. | |
a9c1a157 | 224 | |
ba1c68de | 225 | ** Make the Lucid menu widget display multilingual text. [This |
bf6394a6 DL |
226 | probably needs to be done from actual Emacs buffers, either directly |
227 | in the menu or by rendering in an unmapped window and copying the | |
f677a3a3 SM |
228 | pixels. The current code assumes a specific locale; that isn't good |
229 | enough even if X can render the arbitrary text] [The gtk | |
7bea57c9 DL |
230 | port now displays multilingual text in menus, but only insofar as |
231 | Emacs can encode it as utf-8 and gtk can display the result.] | |
f677a3a3 SM |
232 | Maybe making Lucid menus work like Gtk's (i.e. just force utf-8) is good |
233 | enough now that Emacs can encode most chars into utf-8. | |
a9c1a157 | 234 | |
ba1c68de | 235 | ** Remove the limitation that window and frame widths and heights can |
a9c1a157 RS |
236 | be only full columns/lines. |
237 | ||
ba1c68de SM |
238 | * Other features we would like: |
239 | ||
22f9eb9e CY |
240 | ** Make longlines-mode wrap lines based on screen position instead |
241 | of character position, so that variable-width fonts can be handled | |
242 | properly. | |
243 | ||
c3bb6fdb SM |
244 | ** Allow frames(terminals) created by emacsclient to inherit their environment |
245 | from the emacsclient process. | |
a37288ad SM |
246 | ** Remove the default toggling behavior of minor modes when called from elisp |
247 | rather than interactively. This a trivial one-liner in easy-mode.el. | |
0de301ed | 248 | |
a53e64cc SM |
249 | ** Create a category of errors called `user-error' for errors which are |
250 | typically due to pilot errors and should thus be in debug-ignored-errors. | |
251 | ||
39eadb4a RS |
252 | ** Give Tar mode all the features of Archive mode. |
253 | ||
9b8453da RS |
254 | ** Create a category of errors called `process-error' |
255 | for some or all errors associated with using subprocesses. | |
256 | ||
51f74c37 RS |
257 | ** Maybe reinterpret `parse-error' as a category of errors |
258 | and put some other errors under it. | |
259 | ||
1a500a73 | 260 | ** A function to tell you the argument pattern of functions. |
1b2105d9 | 261 | See `function-arity' in http://www.loveshack.ukfsn.org/emacs/fx-misc.el. |
1a500a73 RS |
262 | |
263 | ** Make byte-compile warn when a doc string is too wide. | |
264 | ||
9f4ba075 CY |
265 | ** Make byte-optimization warnings issue accurate line numbers. |
266 | ||
f95a20e7 RS |
267 | ** A function to check for customizable options that have been |
268 | set but not saved, and ask the user whether to save them. | |
269 | This could go in kill-emacs-query-functions, to remind people | |
270 | to save their changes. If the user says yes, show them | |
271 | in a Custom buffer using customize-customized. | |
272 | ||
8c9676fb DK |
273 | ** Record the sxhash of the default value for customized variables |
274 | and notify the user (maybe by adding a menu item or toolbar button, | |
275 | as the detection can occur during autoload time) when the default | |
276 | changes (meaning that new versions of the Lisp source with a changed | |
277 | default value got installed) and offer ediff on the respective | |
278 | customization buffers. | |
279 | ||
e0402468 | 280 | ** Emacs Lisp mode could put an overlay on the defun for every |
8c9676fb DK |
281 | function that has advice. The overlay could have `after-text' like |
282 | " [Function has advice]". It might look like (defun foo [Function | |
283 | has advice] (x y) The overlay could also be a button that you could | |
284 | use to view the advice. | |
e0402468 | 285 | |
17e55b2a RS |
286 | ** Add a function to get the insertion-type of the markers in an overlay. |
287 | ||
9c9c88db SM |
288 | ** ange-ftp |
289 | *** understand sftp | |
1b2105d9 EZ |
290 | This is hard to make work because sftp doesn't print status |
291 | messages. | |
292 | ||
9c9c88db SM |
293 | *** Use MLS for ange-ftp-insert-directory if a list of files is specified. |
294 | ||
ba1c68de SM |
295 | ** Ability to map a key, including all modified-combinations. |
296 | E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up | |
297 | M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 -> | |
298 | H-S-C-M-s-double-wheel-up, ... | |
a9c1a157 | 299 | |
ba1c68de SM |
300 | ** Beefed-up syntax-tables. |
301 | *** recognize multi-character syntactic entities like `begin' and `end'. | |
302 | *** nested string-delimiters (for Postscript's (foo(bar)baz) strings). | |
303 | *** support for infix operators (with precedence). | |
304 | *** support for the $ (paired delimiter) in parse-partial-sexp. | |
305 | *** support for hook-chars whose effect on the parsing-state is specified | |
306 | by elisp code. Thus a char could both close a string and open a comment | |
307 | at the same time and do it in a context-sensitive way. | |
308 | *** ability to add mode-specific data to the partial-parse-state. | |
309 | ||
2d1ef312 RS |
310 | ** Add a way to convert a keyboard macro to equivalent Lisp code. |
311 | ||
ba1c68de | 312 | ** Have a command suggestion help system that recognizes patterns |
a9c1a157 RS |
313 | of commands which could be replaced with a simpler common command. |
314 | It should not make more than one suggestion per 10 minutes. | |
6165b6e3 | 315 | |
ba1c68de | 316 | ** Add a way to define input methods by computing them (when first used) |
30a2aafd RS |
317 | from other input methods. Then redefine C-x 8 to use a |
318 | user-selected input method, with the default being the union of | |
319 | latin-1-prefix and latin-1-postfix. | |
320 | ||
a7abe867 | 321 | ** Switch the Windows port to using Unicode keyboard input (maybe). |
2fa4f835 EZ |
322 | Based on http://msdn2.microsoft.com/en-us/library/ms633586.aspx, |
323 | this boils down to (1) calling RegisterClassW function to register | |
324 | Emacs windows, and (2) modifying ALL system messages to use Unicode. | |
325 | In particular, WM_CHAR messages, which result from keyboard input, | |
a7abe867 | 326 | will then come in encoded in UTF-16. |
2fa4f835 EZ |
327 | |
328 | One advantage of switching to Unicode is to toss encoded-kbd usage, | |
329 | which will solve the problem with binding non-ASCII keys with | |
330 | modifiers. | |
331 | ||
a7abe867 RS |
332 | Problem: using this on Windows 9x/ME requires installing the |
333 | Microsoft Layer for Unicode (MSLU), which might not implement all | |
334 | the required functionality that is available built-in on Windows XP | |
335 | and later. We should not make this change if it would pressure | |
336 | users of unauthorized copies of older versions of Windows to | |
337 | downgrade to versions that require activation. | |
338 | ||
ba1c68de | 339 | ** Implement a clean way to use different major modes for |
06382b71 RS |
340 | different parts of a buffer. This could be useful in editing |
341 | Bison input files, for instance, or other kinds of text | |
1b2105d9 EZ |
342 | where one language is embedded in another language. See |
343 | http://www.loveshack.ukfsn.org/emacs/multi-mode.el and also | |
344 | mmm-mode, as reference for approaches took by others. | |
a933dad1 | 345 | |
b76781cd RS |
346 | ** Arrange a way for an input method to return the first character |
347 | immediately, then replace it later. So that C-s a with | |
348 | input method latin-1-postfix would immediately search for an a. | |
a933dad1 | 349 | |
ba1c68de | 350 | ** Give start-process the ability to direct standard-error |
a933dad1 DL |
351 | output to a different filter. |
352 | ||
ba1c68de | 353 | ** Make desktop.el save the "frame configuration" of Emacs (in some |
a933dad1 DL |
354 | useful sense). |
355 | ||
ba1c68de | 356 | ** Give desktop.el a feature to switch between different named |
8ba148c7 RS |
357 | desktops. |
358 | ||
ba1c68de | 359 | ** Replace finder.el with something that generates an Info file |
e39fc314 DL |
360 | which gives the same information through a menu structure. [Dave |
361 | Love started on this.] | |
a933dad1 | 362 | |
10bb671b RS |
363 | ** Add a cpio mode, more or less like tar mode. |
364 | ||
ba1c68de | 365 | ** Implement a variant of uncompress.el or jka-compr.el that works with |
2794f7ab DL |
366 | GNU Privacy Guard for encryption. [Code exists but isn't assigned. |
367 | See the Gnus development sources for assigned code concerning GPG | |
1b2105d9 EZ |
368 | use with mail, which is probably a good start.] See also |
369 | http://www.loveshack.ukfsn.org/emacs/auto-crypt.tgz. | |
a933dad1 | 370 | |

371 | ** Save undo information in special temporary files, and reload it |
372 | when needed for undoing. This could extend undo capacity. | |
a933dad1 | 373 | |
ba1c68de | 374 | ** Change the Windows NT menu code |
a933dad1 DL |
375 | so that it handles the deep_p argument and avoids |
376 | regenerating the whole menu bar menu tree except | |
377 | when the user tries to use the menubar. | |
378 | ||
379 | This requires the RIT to forward the WM_INITMENU message to | |
380 | the main thread, and not return from that message until the main | |
0245b3ef | 381 | thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated |
a933dad1 | 382 | the whole menu bar. In the mean time, it should process other messages. |
d054101f | 383 | |
ba1c68de | 384 | ** Get some major packages installed: W3 (development version needs |
93a759ba | 385 | significant work), PSGML, _possibly_ Cedet and ECB. |
590394eb GM |
386 | http://lists.gnu.org/archive/html/emacs-devel/2007-05/msg01493.html |
387 | Check the assignments file for other packages which might go in and | |
388 | have been missed. | |
389 | ||
7d6f3b3a GM |
390 | ** Possibly install python-mode in place of python.el, or combine the two. |
391 | Someone needs to do the work of figuring out who all the non-trivial | |
392 | python-mode.el contributors are and getting assignments. | |

397 | ||
ba1c68de | 398 | ** Make keymaps a first-class Lisp object (this means a rewrite of |
5dd31b13 SM |
399 | keymap.c). What should it do apart from being opaque ? |
400 | multiple inheritance ? faster where-is ? no more fix_submap_inheritance ? | |
401 | what else ? | |
e39fc314 | 402 | |
ba1c68de | 403 | ** Provide real menus on ttys. The MS-DOS implementation can serve as |
2fa4f835 | 404 | an example how to do part of this; see the XMenu* functions on msdos.c. |
e39fc314 | 405 | |
ba1c68de | 406 | ** Implement popular parts of the rest of the CL functions as compiler |
e39fc314 DL |
407 | macros in cl-macs. |
408 | ||
261b01c6 RS |
409 | ** Make compiler warnings about functions that might be undefined at run time |
410 | smarter, so that they know which files are required by the file being | |
411 | compiled and don't warn about functions defined in them. | |
412 | ||
ba1c68de | 413 | ** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA, |
a52ce7f8 | 414 | but it's a valuable feature worth making more general. |
e39fc314 | 415 | |
ba1c68de | 416 | ** Provide MIME support for Rmail using the Gnus MIME library. [Maybe |
bf6394a6 DL |
417 | not now feasible, given Gnus maintenance decisions. fx looked at |
418 | this and can say where some of the problems are.] | |
e39fc314 | 419 | |
ba1c68de | 420 | ** Eliminate the storm of warnings concerning char/unsigned char |
1b2105d9 EZ |
421 | mismatches that we get with GCC 4.x and proprietary compilers on |
422 | various systems. They make it difficult to spot the important | |
423 | warnings. | |
e39fc314 | 424 | |
ba1c68de | 425 | ** Fix anything necessary to use `long long' EMACS_INTs with GCC. |
eaf67bae | 426 | |
ba1c68de | 427 | ** Split out parts of lisp.h and generate Makefile dependencies |
eaf67bae DL |
428 | automatically. |
429 | ||
ba1c68de | 430 | ** Update the FAQ. |
eaf67bae | 431 | |
ba1c68de | 432 | ** Allow auto-compression-mode to use zlib calls if zlib is available. |
b04f7626 | 433 | [It's required for PNG, so may be linked anyhow.] |
1265b539 | 434 | |
ba1c68de | 435 | ** Add a --pristine startup flag which does -q --no-site-file plus |
1265b539 DL |
436 | ignoring X resources (Doze equivalents?) and most of the |
437 | environment. What should not be ignored needs consideration. | |
590394eb | 438 | [Do the existing -Q and -D cover this, or is more needed?] |
1265b539 | 439 | |
ba1c68de | 440 | ** Improve the GC (generational, incremental). (We may be able to use |
7bea57c9 DL |
441 | the Boehm collector.) [See the Boehm-GC branch in CVS for work on |
442 | this.] | |
19cc91fb | 443 | |
ba1c68de | 444 | ** Check what hooks would help Emacspeak -- see the defadvising in W3. |
e2849090 | 445 | |
a5bd14d3 RS |
446 | ** Add definitions for symbol properties, for documentation purposes. |
447 | ||
ba1c68de | 448 | ** Add horizontal scroll bars. |
00a18b59 | 449 | |
ba1c68de | 450 | ** Provide an optional feature which computes a scroll bar slider's |
e4ded23c | 451 | size and its position from lines instead of characters. |
c0460c17 | 452 | |
ba1c68de | 453 | ** Allow unknown image types to be rendered via an external program |
590394eb GM |
454 | converting them to, say, PBM (in the same way as PostScript?). [does |
455 | doc-view.el do this, or could it be extended to do this?] | |
d1c3f6b6 | 456 | |
ba1c68de | 457 | ** Allow displaying an X window from an external program in a buffer, |
d1c3f6b6 RS |
458 | e.g. to render graphics from Java applets. [gerd and/or wmperry |
459 | thought this was feasible.] | |
460 | ||
ba1c68de | 461 | ** Allow images (not just text) in the margin to be mouse-sensitive. |
d1c3f6b6 RS |
462 | (Requires recursing through display properties). Provide some way |
463 | to simulate mouse-clicks on marginal text without a mouse. | |
464 | ||
ba1c68de | 465 | ** Implement Lisp functions to determine properly whether a character |
d1c3f6b6 RS |
466 | is displayable (particularly needed in XFree 4, sigh). Use it to |
467 | define useful glyphs that may be displayed as images or unicodes | |
468 | (with ASCIIfied fallback via latin1-disp). Examples include | |
469 | box-drawing graphics in Custom buffers, W3 rules and tables, and | |
470 | tree displays generally, mode-line mail indicator. [See work done | |
8589dc17 | 471 | already for Emacs 23 and consult fx.] |
d1c3f6b6 | 472 | |
ba1c68de | 473 | ** Do something to make rms happy with fx's dynamic loading, and use it |
d1c3f6b6 RS |
474 | to implement things like auto-loaded buffer parsers and database |
475 | access in cases which need more than Lisp. | |
476 | ||
ba1c68de | 477 | ** Extend ps-print to deal with multiple font sizes, images, and extra |
d1c3f6b6 RS |
478 | encodings. |
479 | ||
ba1c68de | 480 | ** Provide portable undumping using mmap (per gerd design). |
d1c3f6b6 | 481 | |
48b194fd RS |
482 | ** Make byte-compile avoid binding an expanded defsubst's args |
483 | when the body only calls primitives. | |
484 | ||
ba1c68de | 485 | ** Use the XIE X extension, if available, for image display. |
e641b454 | 486 | |
ba1c68de | 487 | ** Make monochrome images display using the foreground and background |
51fe665a RS |
488 | colors of the applicable faces. |
489 | ||
d101bf56 RS |
490 | ** Face remapping. |
491 | ||
ec68482b RS |
492 | ** Make `format-time-string' preserve text properties like `format'. |
493 | ||
fda12b27 RS |
494 | ** Optionally make the cursor a little thinner at the end of a line |
495 | or the end of the buffer. | |
496 | ||
ba1c68de | 497 | ** Port the conservative stack marking code of Emacs' garbage collector |
1b2105d9 EZ |
498 | to more systems, so that we can completely get rid of GCPROs. Note |
499 | that Boehm garbage collector provides this. | |
5e101746 | 500 | |
ba1c68de | 501 | ** Reorder defcustom's in each package so that the more important |
5005a9c0 EZ |
502 | options come first in the Customize buffers. This could be done by |
503 | either rearranging the file (since options are shown in the order | |
504 | they appear in the *.el files), or by adding a few :set-after | |
505 | attributes. | |
506 | ||
ba1c68de | 507 | ** Maybe document the features of libraries missing from the manual (or |
5e101746 RS |
508 | ancillary manuals, including the Lisp manual in some cases). |
509 | This is not worth doing for all of these packages and we need not | |
510 | aim for completeness, but some may be worth documenting. | |
511 | ||
512 | Here's a list which is probably not complete/correct: align, allout, | |
513 | artist, ansi-color, array, battery, calculator, cdl, cmuscheme, | |
657c5358 | 514 | completion, cua, delim-col, dirtrack, double, echistory, elide-head, |
5e101746 RS |
515 | easymenu, expand, flow-ctrl, format [format-alist], |
516 | generic/generic-x [various modes], kermit, log-edit, ledit | |
517 | [obsolete?], makesum, midnight [other than in Kill Buffer node], | |
518 | mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile, | |
519 | snmp-mode [?], soundex [should be interactive?], strokes [start from | |
520 | the web page], talk, thingatpt [interactive functions?], type-break, | |
521 | vcursor, xscheme, zone-mode [?], mlconvert [?], iso-cvt, iso-swed, | |
522 | swedish, feedmail [?], uce, bruce, gametree, meese, page-ext, | |
523 | refbib, refer, scribe, sgml-mode, spell, texinfo, underline, | |
524 | cmacexp, hideif, mantemp [obsolete?], pcomplete, assoc, xml, | |
525 | cvs-status (should be described in PCL-CVS manual); other progmodes, | |
526 | probably in separate manual. | |
758830ba | 527 | |
ba1c68de | 528 | ** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap |
6772c8e1 GM |
529 | the XPMs so that the color versions work generally. (Requires care |
530 | with the color used for the transparent regions.) | |
bf6394a6 | 531 | |
ba1c68de | 532 | ** Convenient access to the `values' variable. It would be nice to have an |
758830ba JB |
533 | interface that would show you the printed reps of the elements of the |
534 | list in a menu, let you select one of the values, and put it into some | |
535 | other variable, without changing the value of `values'. | |
bf6394a6 | 536 | |
ba1c68de | 537 | ** (Controlled by a flag) make open and close syntax match exactly, |
c51b37fd DL |
538 | i.e. `(' doesn't match `]'. |
539 | ||
ba1c68de | 540 | ** Specify parameter ID-FORMAT in all calls to `file-attributes' and |
9ac8c83b LH |
541 | `directory-files-and-attributes' where attributes UID or GID are used. |
542 | Whenever possible, use value 'string. | |
543 | When done, change meaning of default value from 'integer to 'string. | |
544 | If value 'integer is used nowhere, remove the parameter ID-FORMAT from | |
545 | the definition of `file-attributes' and `directory-files-and-attributes' | |
546 | and from the calls. | |
547 | ||
cf4c9271 KH |
548 | ** Make language-info-alist customizable. Currently a user can customize |
549 | only the variable `current-language-environment'. | |
550 | ||
551 | ** Improve language environment handling so that Emacs can fit | |
552 | better to a users locale. Currently Emacs uses utf-8 language | |
553 | environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale | |
554 | are also put in utf-8 lang. env. In such a case, it is | |
555 | better to use Japanese lang. env. but prefer utf-8 coding system. | |
1f724d55 | 556 | |
321e4870 RS |
557 | ** Enhance locale handling: handle language, territory and charset |
558 | orthogonally and de-emphasize language environments. Use the locale | |
559 | to set up more things, such as fontsets, the default Ispell | |
560 | dictionary, diary format, calendar holidays and display, quoting | |
561 | characters and phrase boundaries, sentence endings, collation for | |
562 | sorting (at least for unicodes), HTTP Accept-language, patterns for | |
563 | directory listings and compilation messages, yes-or-no replies, | |
564 | common menu items when the toolkit supports it ... `locale-info' | |
565 | needs extending for LC_COLLATE &c. [fx started on this.] | |
566 | ||
1f724d55 KH |
567 | ** Eliminate the current restriction on header printing by ps-print. |
568 | Currently, a header can contain only single 1-byte charset in | |
569 | addition to ASCII. | |
570 | ||
571 | ** In ps-print, provide an user friendly interface to specify fonts. | |
572 | ||
1f724d55 KH |
573 | ** Enhance word boundary detection for such a script that doesn't use |
574 | space at word boundary (e.g. Thai). | |
575 | ||
cf4c9271 KH |
576 | ** Implement interface programs with major Japanese conversion server |
577 | in lib-src so that they can be used from the input method | |
578 | "japanese". Currently, most Japanese users are using external | |
579 | packages (e.g. tamago, anthy) or an input method via XIM. | |
1f724d55 | 580 | |
a53e64cc SM |
581 | ** Let LEIM handle the Mode_switch key like XIM does (i.e. a toggle like C-\ |
582 | but which can also be used as a modifier). | |
583 | ||
d59e3c42 NR |
584 | ** Improve Help buffers: Change the face of previously visited links (like |
585 | Info, but also with regard to namespace), add a forward button to make the | |
586 | Help buffer more browser like and gives the value of lisp expressions | |
587 | e.g auto-mode-alist, the right face. [nickrob@snap.net.nz has a patch | |
588 | for this for inclusion after 22.1]. | |
589 | ||
5a473319 GM |
590 | ** Possibly make `list-holidays' eval items in the calendar-holidays variable. |
591 | See thread | |
592 | <http://lists.gnu.org/archive/html/emacs-devel/2006-02/msg01034.html>. | |
593 | [rgm@gnu.org will look at this after 22.1] | |
594 | ||
9e21382c GM |

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

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