3 | If you are ready to start working on any of these TODO items, we |
4 | appreciate your help; please write to emacs-devel@gnu.org so we can be | |
5 | aware that the problem is being addressed, and talk with you how to do | |
7bea57c9 | 6 | it best. Since Emacs is an FSF-copyrighted package, please be |
2255d5b4 RS |
7 | prepared to sign legal papers to transfer the copyright on your work |
8 | to the FSF. | |

ba1c68de | 10 | * Small but important fixes needed in existing features: |
a9c1a157 | 11 | |
d3a403e5 | 12 | ** Fix the kill/yank treatment of invisible text. At the moment, |
b9e6b498 GM |
13 | invisible text is placed in the kill-ring, so that the contents of |
14 | the ring may not correspond to the text as displayed to the user. It | |
15 | ought to be possible to omit text which is invisible (due to a | |
16 | text-property, overlay, or selective display) from the kill-ring. | |
17 | ||
56011a8c RS |
18 | ** battery.el display-battery should be replaced with a minor mode. |
19 | ||
d9c1ce9d RS |
20 | ** Redefine define-generic-mode as a macro, so the compiler |
21 | sees the definitions it generates. | |
22 | ||
6f771c32 RS |
23 | ** Change the way define-minor-mode handles autoloading. |
24 | It should not generate :require. Or :require in defcustom | |
25 | should not be recorded in the user's custom-set-variables call. | |
26 | ||
ba1c68de | 27 | * Important features: |
a9c1a157 | 28 | |
ba1c68de | 29 | ** Provide user-friendly ways to list all available font families, |
bf6394a6 DL |
30 | display a font as a sample, etc. [fx is looking at multilingual |
31 | font selection for Emacs 22.] | |
5e101746 | 32 | |
ba1c68de | 33 | ** Program Enriched mode to read and save in RTF. [Is there actually a |
c51b37fd DL |
34 | decent single definition of RTF? Maybe see info at |
35 | http://latex2rtf.sourceforge.net/.] | |
6165b6e3 | 36 | |
ba1c68de | 37 | ** Implement something better than the current Refill mode. This |
a9c1a157 RS |
38 | probably needs some primitive support. |
39 | ||
ba1c68de | 40 | ** Implement primitive and higher-level functions to allow filling |
a9c1a157 RS |
41 | properly with variable-pitch faces. |
42 | ||
ba1c68de | 43 | ** Implement a smoother vertical scroll facility, one that allows |
d3a403e5 SM |
44 | C-v to scroll through a tall image. The primitive operations |
45 | posn-at-point and posn-at-x-y should now make it doable in elisp. | |
a9c1a157 | 46 | |
6ca1c497 RS |
47 | ** Implement intelligent search/replace, going beyond query-replace |
48 | (see http://graphics.csail.mit.edu/~rcm/chi04.pdf). | |
49 | ||
ba1c68de SM |
50 | ** Implement other text formatting properties. |
51 | *** Footnotes that can appear either in place or at the end of the page. | |
52 | *** text property that says "don't break line in middle of this". | |
6165b6e3 EZ |
53 | Don't break the line between two characters that have the |
54 | same value of this property. | |
ba1c68de | 55 | *** Discretionary hyphens that are not visible when they are at end of line. |
6165b6e3 | 56 | |
ba1c68de | 57 | ** Make movemail work with IMAP. |
a9c1a157 | 58 | |
ba1c68de | 59 | ** Internationalize Emacs's messages. [Note that this is of limited |
bf6394a6 DL |
60 | use until the menus can display multilingual text. It also doesn't |
61 | address important issues like using the names of symbols essentially | |
62 | as documentation, e.g. in command names and Custom. -- fx] | |
a9c1a157 | 63 | |
ba1c68de | 64 | ** Make the Lucid menu widget display multilingual text. [This |
bf6394a6 DL |
65 | probably needs to be done from actual Emacs buffers, either directly |
66 | in the menu or by rendering in an unmapped window and copying the | |
67 | pixels. Note that the relevant Xlib functions assume a specific | |
68 | locale; that isn't good enough even if X can render the arbitrary | |
7bea57c9 DL |
69 | text, which it often can't as far as I can tell. -- fx] [The gtk |
70 | port now displays multilingual text in menus, but only insofar as | |
71 | Emacs can encode it as utf-8 and gtk can display the result.] | |
a9c1a157 | 72 | |
ba1c68de | 73 | ** Remove the limitation that window and frame widths and heights can |
a9c1a157 RS |
74 | be only full columns/lines. |
75 | ||
ba1c68de SM |
76 | * Other features we would like: |
77 | ||
9c9c88db SM |
78 | ** ange-ftp |
79 | *** understand sftp | |
9c9c88db SM |
80 | *** Use MLS for ange-ftp-insert-directory if a list of files is specified. |
81 | ||
ba1c68de SM |
82 | ** Ability to map a key, including all modified-combinations. |
83 | E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up | |
84 | M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 -> | |
85 | H-S-C-M-s-double-wheel-up, ... | |
a9c1a157 | 86 | |
ba1c68de SM |
87 | ** Beefed-up syntax-tables. |
88 | *** recognize multi-character syntactic entities like `begin' and `end'. | |
89 | *** nested string-delimiters (for Postscript's (foo(bar)baz) strings). | |
90 | *** support for infix operators (with precedence). | |
91 | *** support for the $ (paired delimiter) in parse-partial-sexp. | |
92 | *** support for hook-chars whose effect on the parsing-state is specified | |
93 | by elisp code. Thus a char could both close a string and open a comment | |
94 | at the same time and do it in a context-sensitive way. | |
95 | *** ability to add mode-specific data to the partial-parse-state. | |
96 | ||
2d1ef312 RS |
97 | ** Add a way to convert a keyboard macro to equivalent Lisp code. |
98 | ||
ba1c68de | 99 | ** Have a command suggestion help system that recognizes patterns |
a9c1a157 RS |
100 | of commands which could be replaced with a simpler common command. |
101 | It should not make more than one suggestion per 10 minutes. | |
6165b6e3 | 102 | |
ba1c68de | 103 | ** Add a way to define input methods by computing them (when first used) |
30a2aafd RS |
104 | from other input methods. Then redefine C-x 8 to use a |
105 | user-selected input method, with the default being the union of | |
106 | latin-1-prefix and latin-1-postfix. | |
107 | ||
ba1c68de | 108 | ** Implement a clean way to use different major modes for |
06382b71 RS |
109 | different parts of a buffer. This could be useful in editing |
110 | Bison input files, for instance, or other kinds of text | |
111 | where one language is embedded in another language. | |
a933dad1 | 112 | |
ba1c68de | 113 | ** Give start-process the ability to direct standard-error |
a933dad1 DL |
114 | output to a different filter. |
115 | ||
ba1c68de | 116 | ** Make desktop.el save the "frame configuration" of Emacs (in some |
a933dad1 DL |
117 | useful sense). |
118 | ||
ba1c68de | 119 | ** Give desktop.el a feature to switch between different named |
8ba148c7 RS |
120 | desktops. |
121 | ||
ba1c68de | 122 | ** Replace finder.el with something that generates an Info file |
e39fc314 DL |
123 | which gives the same information through a menu structure. [Dave |
124 | Love started on this.] | |
a933dad1 | 125 | |
ba1c68de | 126 | ** Implement a variant of uncompress.el or jka-compr.el that works with |
2794f7ab DL |
127 | GNU Privacy Guard for encryption. [Code exists but isn't assigned. |
128 | See the Gnus development sources for assigned code concerning GPG | |
129 | use with mail, which is probably a good start.] | |
a933dad1 | 130 | |
06382b71 RS |
131 | ** Save undo information in special temporary files, and reload it |
132 | when needed for undoing. This could extend undo capacity. | |
a933dad1 | 133 | |
ba1c68de | 134 | ** Change the Windows NT menu code |
a933dad1 DL |
135 | so that it handles the deep_p argument and avoids |
136 | regenerating the whole menu bar menu tree except | |
137 | when the user tries to use the menubar. | |
138 | ||
139 | This requires the RIT to forward the WM_INITMENU message to | |
140 | the main thread, and not return from that message until the main | |
0245b3ef | 141 | thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated |
a933dad1 | 142 | the whole menu bar. In the mean time, it should process other messages. |
d054101f | 143 | |
ba1c68de | 144 | ** Get some major packages installed: W3 (development version needs |
2794f7ab | 145 | significant work), PSGML. Check the assignments file for other |
a52ce7f8 | 146 | packages which might go in and have been missed. |
e39fc314 | 147 | |
ba1c68de | 148 | ** Make keymaps a first-class Lisp object (this means a rewrite of |
5dd31b13 SM |
149 | keymap.c). What should it do apart from being opaque ? |
150 | multiple inheritance ? faster where-is ? no more fix_submap_inheritance ? | |
151 | what else ? | |
e39fc314 | 152 | |
ba1c68de | 153 | ** Provide real menus on ttys. The MS-DOS implementation can serve as |
e39fc314 DL |
154 | an example how to do part of this. |
155 | ||
ba1c68de | 156 | ** Implement popular parts of the rest of the CL functions as compiler |
e39fc314 DL |
157 | macros in cl-macs. |
158 | ||
261b01c6 RS |
159 | ** Make compiler warnings about functions that might be undefined at run time |
160 | smarter, so that they know which files are required by the file being | |
161 | compiled and don't warn about functions defined in them. | |
162 | ||
ba1c68de | 163 | ** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA, |
a52ce7f8 | 164 | but it's a valuable feature worth making more general. |
e39fc314 | 165 | |
ba1c68de | 166 | ** Support simultaneous tty and X frames. |
e39fc314 | 167 | |
ba1c68de | 168 | ** Provide MIME support for Rmail using the Gnus MIME library. [Maybe |
bf6394a6 DL |
169 | not now feasible, given Gnus maintenance decisions. fx looked at |
170 | this and can say where some of the problems are.] | |
e39fc314 | 171 | |
ba1c68de | 172 | ** Eliminate the storm of warnings concerning char/unsigned char |
e39fc314 DL |
173 | mismatches that we get with proprietary compilers on various systems. |
174 | They make it difficult to spot the important warnings. | |
175 | ||
ba1c68de | 176 | ** Fix anything necessary to use `long long' EMACS_INTs with GCC. |
eaf67bae | 177 | |
ba1c68de | 178 | ** Split out parts of lisp.h and generate Makefile dependencies |
eaf67bae DL |
179 | automatically. |
180 | ||
ba1c68de | 181 | ** Update the FAQ. |
eaf67bae | 182 | |
ba1c68de | 183 | ** Allow auto-compression-mode to use zlib calls if zlib is available. |
b04f7626 | 184 | [It's required for PNG, so may be linked anyhow.] |
1265b539 | 185 | |
ba1c68de | 186 | ** Add a --pristine startup flag which does -q --no-site-file plus |
1265b539 DL |
187 | ignoring X resources (Doze equivalents?) and most of the |
188 | environment. What should not be ignored needs consideration. | |
189 | ||
ba1c68de | 190 | ** Investigate using the language environment (or locale?) to set up |
cf56d05f | 191 | more things, such as the default Ispell dictionary, calendar |
6147334f | 192 | holidays, quoting characters?,... |
34f70eda | 193 | |
ba1c68de | 194 | ** Improve the GC (generational, incremental). (We may be able to use |
7bea57c9 DL |
195 | the Boehm collector.) [See the Boehm-GC branch in CVS for work on |
196 | this.] | |
19cc91fb | 197 | |
ba1c68de | 198 | ** Check what hooks would help Emacspeak -- see the defadvising in W3. |
e2849090 | 199 | |
ba1c68de | 200 | ** Add horizontal scroll bars. |
00a18b59 | 201 | |
ba1c68de | 202 | ** Provide an optional feature which computes a scroll bar slider's |
e4ded23c | 203 | size and its position from lines instead of characters. |
c0460c17 | 204 | |
ba1c68de | 205 | ** Make the Custom themes support do useful things. |
3a84ed60 | 206 | |
ba1c68de | 207 | ** Add support for SVG (Scalable Vector Graphics) rendering to |
296808a5 | 208 | Emacs. |
6add099c | 209 | |
ba1c68de | 210 | ** Allow unknown image types to be rendered via an external program |
d1c3f6b6 RS |
211 | converting them to, say, PBM (in the same way as PostScript?). |
212 | ||
ba1c68de | 213 | ** Allow displaying an X window from an external program in a buffer, |
d1c3f6b6 RS |
214 | e.g. to render graphics from Java applets. [gerd and/or wmperry |
215 | thought this was feasible.] | |
216 | ||
ba1c68de | 217 | ** Allow images (not just text) in the margin to be mouse-sensitive. |
d1c3f6b6 RS |
218 | (Requires recursing through display properties). Provide some way |
219 | to simulate mouse-clicks on marginal text without a mouse. | |
220 | ||
ba1c68de | 221 | ** Implement Lisp functions to determine properly whether a character |
d1c3f6b6 RS |
222 | is displayable (particularly needed in XFree 4, sigh). Use it to |
223 | define useful glyphs that may be displayed as images or unicodes | |
224 | (with ASCIIfied fallback via latin1-disp). Examples include | |
225 | box-drawing graphics in Custom buffers, W3 rules and tables, and | |
226 | tree displays generally, mode-line mail indicator. [See work done | |
227 | already for Emacs 22 and consult fx.] | |
228 | ||
ba1c68de | 229 | ** Do something to make rms happy with fx's dynamic loading, and use it |
d1c3f6b6 RS |
230 | to implement things like auto-loaded buffer parsers and database |
231 | access in cases which need more than Lisp. | |
232 | ||
ba1c68de | 233 | ** Extend ps-print to deal with multiple font sizes, images, and extra |
d1c3f6b6 RS |
234 | encodings. |
235 | ||
ba1c68de | 236 | ** Provide portable undumping using mmap (per gerd design). |
d1c3f6b6 | 237 | |
ba1c68de | 238 | ** Use the XIE X extension, if available, for image display. |
e641b454 | 239 | |
ba1c68de | 240 | ** Make monochrome images display using the foreground and background |
51fe665a RS |
241 | colors of the applicable faces. |
242 | ||
ba1c68de | 243 | ** Add support for rendering antialiased text, probably using |
2a573e69 | 244 | XRender/Freetype. |
c5020b5b | 245 | |
ba1c68de | 246 | ** Port the conservative stack marking code of Emacs' garbage collector |
5e101746 RS |
247 | to more systems, so that we can completely get rid of GCPROs. |
248 | ||
ba1c68de | 249 | ** Reorder defcustom's in each package so that the more important |
5005a9c0 EZ |
250 | options come first in the Customize buffers. This could be done by |
251 | either rearranging the file (since options are shown in the order | |
252 | they appear in the *.el files), or by adding a few :set-after | |
253 | attributes. | |
254 | ||
ba1c68de | 255 | ** Maybe document the features of libraries missing from the manual (or |
5e101746 RS |
256 | ancillary manuals, including the Lisp manual in some cases). |
257 | This is not worth doing for all of these packages and we need not | |
258 | aim for completeness, but some may be worth documenting. | |
259 | ||
260 | Here's a list which is probably not complete/correct: align, allout, | |
261 | artist, ansi-color, array, battery, calculator, cdl, cmuscheme, | |
657c5358 | 262 | completion, cua, delim-col, dirtrack, double, echistory, elide-head, |
5e101746 RS |
263 | easymenu, expand, flow-ctrl, format [format-alist], |
264 | generic/generic-x [various modes], kermit, log-edit, ledit | |
265 | [obsolete?], makesum, midnight [other than in Kill Buffer node], | |
266 | mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile, | |
267 | snmp-mode [?], soundex [should be interactive?], strokes [start from | |
268 | the web page], talk, thingatpt [interactive functions?], type-break, | |
269 | vcursor, xscheme, zone-mode [?], mlconvert [?], iso-cvt, iso-swed, | |
270 | swedish, feedmail [?], uce, bruce, gametree, meese, page-ext, | |
271 | refbib, refer, scribe, sgml-mode, spell, texinfo, underline, | |
272 | cmacexp, hideif, mantemp [obsolete?], pcomplete, assoc, xml, | |
273 | cvs-status (should be described in PCL-CVS manual); other progmodes, | |
274 | probably in separate manual. | |
758830ba | 275 | |
ba1c68de | 276 | ** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap |
bf6394a6 DL |
277 | the XPMs so that the colour versions work generally. (Requires care |
278 | with the colour used for the transparent regions.) | |
279 | ||
ba1c68de | 280 | ** Convenient access to the `values' variable. It would be nice to have an |
758830ba JB |
281 | interface that would show you the printed reps of the elements of the |
282 | list in a menu, let you select one of the values, and put it into some | |
283 | other variable, without changing the value of `values'. | |
bf6394a6 | 284 | |
ba1c68de | 285 | ** (Controlled by a flag) make open and close syntax match exactly, |
c51b37fd DL |
286 | i.e. `(' doesn't match `]'. |
287 | ||
ba1c68de | 288 | ** Specify parameter ID-FORMAT in all calls to `file-attributes' and |
9ac8c83b LH |
289 | `directory-files-and-attributes' where attributes UID or GID are used. |
290 | Whenever possible, use value 'string. | |
291 | When done, change meaning of default value from 'integer to 'string. | |
292 | If value 'integer is used nowhere, remove the parameter ID-FORMAT from | |
293 | the definition of `file-attributes' and `directory-files-and-attributes' | |
294 | and from the calls. | |
295 | ||
cf4c9271 KH |
296 | ** Make language-info-alist customizable. Currently a user can customize |
297 | only the variable `current-language-environment'. | |
298 | ||
299 | ** Improve language environment handling so that Emacs can fit | |
300 | better to a users locale. Currently Emacs uses utf-8 language | |
301 | environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale | |
302 | are also put in utf-8 lang. env. In such a case, it is | |
303 | better to use Japanese lang. env. but prefer utf-8 coding system. | |
1f724d55 KH |
304 | |
305 | ** Eliminate the current restriction on header printing by ps-print. | |
306 | Currently, a header can contain only single 1-byte charset in | |
307 | addition to ASCII. | |
308 | ||
309 | ** In ps-print, provide an user friendly interface to specify fonts. | |
310 | ||
311 | ** OpenType font support for various complex scripts (e.g. Devanagari). | |
312 | As X protocal doesn't provide a way to access OpenType Layout Tables | |
313 | in a OpenType font of a server side, we need a way to utilize local | |
314 | fonts (perhaps by directly using the Freetype library or indirectly | |
315 | via Xft library). | |
316 | ||
317 | ** Enhance word boundary detection for such a script that doesn't use | |
318 | space at word boundary (e.g. Thai). | |
319 | ||
cf4c9271 KH |
320 | ** Implement interface programs with major Japanese conversion server |
321 | in lib-src so that they can be used from the input method | |
322 | "japanese". Currently, most Japanese users are using external | |
323 | packages (e.g. tamago, anthy) or an input method via XIM. | |
1f724d55 | 324 | |
ba1c68de SM |
325 | * Internal changes |
326 | ||
327 | ** Replace gmalloc.c with the modified Doug Lea code from the current | |
328 | GNU libc so that the special mmapping of buffers can be removed -- | |
329 | that apparently loses under Solaris, at least. [fx has mostly done | |
330 | this.] | |
331 | ||
332 | ** Rewrite make-docfile to be clean and maintainable. | |
333 | ||
334 | ** Add an inferior-comint-minor-mode to capture the common set of operations | |
335 | offered by major modes that offer an associated inferior | |
d3a403e5 SM |
336 | comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic. |
337 | For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode, | |
338 | haskell-mode, tuareg-mode, ... | |
