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 | |
ba1c68de | 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 | ||
ba1c68de | 18 | * Important features: |
a9c1a157 | 19 | |
ba1c68de | 20 | ** Provide user-friendly ways to list all available font families, |
bf6394a6 DL |
21 | display a font as a sample, etc. [fx is looking at multilingual |
22 | font selection for Emacs 22.] | |
5e101746 | 23 | |
ba1c68de | 24 | ** Program Enriched mode to read and save in RTF. [Is there actually a |
c51b37fd DL |
25 | decent single definition of RTF? Maybe see info at |
26 | http://latex2rtf.sourceforge.net/.] | |
6165b6e3 | 27 | |
ba1c68de | 28 | ** Implement something better than the current Refill mode. This |
a9c1a157 RS |
29 | probably needs some primitive support. |
30 | ||
ba1c68de | 31 | ** Implement primitive and higher-level functions to allow filling |
a9c1a157 RS |
32 | properly with variable-pitch faces. |
33 | ||
ba1c68de | 34 | ** Implement a smoother vertical scroll facility, one that allows |
d1c3f6b6 | 35 | C-v to scroll through a tall image. |
a9c1a157 | 36 | |
ba1c68de SM |
37 | ** Implement other text formatting properties. |
38 | *** Footnotes that can appear either in place or at the end of the page. | |
39 | *** text property that says "don't break line in middle of this". | |
6165b6e3 EZ |
40 | Don't break the line between two characters that have the |
41 | same value of this property. | |
ba1c68de | 42 | *** Discretionary hyphens that are not visible when they are at end of line. |
6165b6e3 | 43 | |
ba1c68de | 44 | ** Make movemail work with IMAP. |
a9c1a157 | 45 | |
ba1c68de | 46 | ** Internationalize Emacs's messages. [Note that this is of limited |
bf6394a6 DL |
47 | use until the menus can display multilingual text. It also doesn't |
48 | address important issues like using the names of symbols essentially | |
49 | as documentation, e.g. in command names and Custom. -- fx] | |
a9c1a157 | 50 | |
ba1c68de | 51 | ** Make the Lucid menu widget display multilingual text. [This |
bf6394a6 DL |
52 | probably needs to be done from actual Emacs buffers, either directly |
53 | in the menu or by rendering in an unmapped window and copying the | |
54 | pixels. Note that the relevant Xlib functions assume a specific | |
55 | locale; that isn't good enough even if X can render the arbitrary | |
7bea57c9 DL |
56 | text, which it often can't as far as I can tell. -- fx] [The gtk |
57 | port now displays multilingual text in menus, but only insofar as | |
58 | Emacs can encode it as utf-8 and gtk can display the result.] | |
a9c1a157 | 59 | |
ba1c68de | 60 | ** Remove the limitation that window and frame widths and heights can |
a9c1a157 RS |
61 | be only full columns/lines. |
62 | ||
ba1c68de SM |
63 | * Other features we would like: |
64 | ||
65 | ** Ability to map a key, including all modified-combinations. | |
66 | E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up | |
67 | M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 -> | |
68 | H-S-C-M-s-double-wheel-up, ... | |
a9c1a157 | 69 | |
ba1c68de SM |
70 | ** Beefed-up syntax-tables. |
71 | *** recognize multi-character syntactic entities like `begin' and `end'. | |
72 | *** nested string-delimiters (for Postscript's (foo(bar)baz) strings). | |
73 | *** support for infix operators (with precedence). | |
74 | *** support for the $ (paired delimiter) in parse-partial-sexp. | |
75 | *** support for hook-chars whose effect on the parsing-state is specified | |
76 | by elisp code. Thus a char could both close a string and open a comment | |
77 | at the same time and do it in a context-sensitive way. | |
78 | *** ability to add mode-specific data to the partial-parse-state. | |
79 | ||
80 | ** Have a command suggestion help system that recognizes patterns | |
a9c1a157 RS |
81 | of commands which could be replaced with a simpler common command. |
82 | It should not make more than one suggestion per 10 minutes. | |
6165b6e3 | 83 | |
ba1c68de | 84 | ** Add a way to define input methods by computing them (when first used) |
30a2aafd RS |
85 | from other input methods. Then redefine C-x 8 to use a |
86 | user-selected input method, with the default being the union of | |
87 | latin-1-prefix and latin-1-postfix. | |
88 | ||
ba1c68de | 89 | ** Implement a clean way to use different major modes for |
a933dad1 DL |
90 | different parts of a buffer. |
91 | ||
ba1c68de | 92 | ** Give start-process the ability to direct standard-error |
a933dad1 DL |
93 | output to a different filter. |
94 | ||
ba1c68de | 95 | ** Make desktop.el save the "frame configuration" of Emacs (in some |
a933dad1 DL |
96 | useful sense). |
97 | ||
ba1c68de | 98 | ** Give desktop.el a feature to switch between different named |
8ba148c7 RS |
99 | desktops. |
100 | ||
ba1c68de | 101 | ** Replace finder.el with something that generates an Info file |
e39fc314 DL |
102 | which gives the same information through a menu structure. [Dave |
103 | Love started on this.] | |
a933dad1 | 104 | |
ba1c68de | 105 | ** Implement a variant of uncompress.el or jka-compr.el that works with |
2794f7ab DL |
106 | GNU Privacy Guard for encryption. [Code exists but isn't assigned. |
107 | See the Gnus development sources for assigned code concerning GPG | |
108 | use with mail, which is probably a good start.] | |
a933dad1 | 109 | |
ba1c68de | 110 | ** Save undo information in files, and reload it when needed |
a933dad1 DL |
111 | for undoing. |
112 | ||
ba1c68de | 113 | ** Merge the Emacs regex.c with the Glibc regex.c. |
bf6394a6 | 114 | They split off a few years ago through negligence. |
7665519d | 115 | |
ba1c68de | 116 | ** Change the Windows NT menu code |
a933dad1 DL |
117 | so that it handles the deep_p argument and avoids |
118 | regenerating the whole menu bar menu tree except | |
119 | when the user tries to use the menubar. | |
120 | ||
121 | This requires the RIT to forward the WM_INITMENU message to | |
122 | the main thread, and not return from that message until the main | |
0245b3ef | 123 | thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated |
a933dad1 | 124 | the whole menu bar. In the mean time, it should process other messages. |
d054101f | 125 | |
ba1c68de | 126 | ** Get some major packages installed: W3 (development version needs |
2794f7ab | 127 | significant work), PSGML. Check the assignments file for other |
a52ce7f8 | 128 | packages which might go in and have been missed. |
e39fc314 | 129 | |
ba1c68de | 130 | ** Make keymaps a first-class Lisp object (this means a rewrite of |
5dd31b13 SM |
131 | keymap.c). What should it do apart from being opaque ? |
132 | multiple inheritance ? faster where-is ? no more fix_submap_inheritance ? | |
133 | what else ? | |
e39fc314 | 134 | |
ba1c68de | 135 | ** Provide real menus on ttys. The MS-DOS implementation can serve as |
e39fc314 DL |
136 | an example how to do part of this. |
137 | ||
ba1c68de | 138 | ** Implement popular parts of the rest of the CL functions as compiler |
e39fc314 DL |
139 | macros in cl-macs. |
140 | ||
ba1c68de | 141 | ** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA, |
a52ce7f8 | 142 | but it's a valuable feature worth making more general. |
e39fc314 | 143 | |
ba1c68de | 144 | ** Support simultaneous tty and X frames. |
e39fc314 | 145 | |
ba1c68de | 146 | ** Provide MIME support for Rmail using the Gnus MIME library. [Maybe |
bf6394a6 DL |
147 | not now feasible, given Gnus maintenance decisions. fx looked at |
148 | this and can say where some of the problems are.] | |
e39fc314 | 149 | |
ba1c68de | 150 | ** Eliminate the storm of warnings concerning char/unsigned char |
e39fc314 DL |
151 | mismatches that we get with proprietary compilers on various systems. |
152 | They make it difficult to spot the important warnings. | |
153 | ||
ba1c68de | 154 | ** Fix anything necessary to use `long long' EMACS_INTs with GCC. |
eaf67bae | 155 | |
ba1c68de | 156 | ** Split out parts of lisp.h and generate Makefile dependencies |
eaf67bae DL |
157 | automatically. |
158 | ||
ba1c68de | 159 | ** Update the FAQ. |
eaf67bae | 160 | |
ba1c68de | 161 | ** Allow auto-compression-mode to use zlib calls if zlib is available. |
b04f7626 | 162 | [It's required for PNG, so may be linked anyhow.] |
1265b539 | 163 | |
ba1c68de | 164 | ** Add a --pristine startup flag which does -q --no-site-file plus |
1265b539 DL |
165 | ignoring X resources (Doze equivalents?) and most of the |
166 | environment. What should not be ignored needs consideration. | |
167 | ||
ba1c68de | 168 | ** Investigate using the language environment (or locale?) to set up |
cf56d05f | 169 | more things, such as the default Ispell dictionary, calendar |
6147334f | 170 | holidays, quoting characters?,... |
34f70eda | 171 | |
ba1c68de | 172 | ** Improve the GC (generational, incremental). (We may be able to use |
7bea57c9 DL |
173 | the Boehm collector.) [See the Boehm-GC branch in CVS for work on |
174 | this.] | |
19cc91fb | 175 | |
ba1c68de | 176 | ** Check what hooks would help Emacspeak -- see the defadvising in W3. |
e2849090 | 177 | |
ba1c68de | 178 | ** Add horizontal scroll bars. |
00a18b59 | 179 | |
ba1c68de | 180 | ** Provide an optional feature which computes a scroll bar slider's |
e4ded23c | 181 | size and its position from lines instead of characters. |
c0460c17 | 182 | |
ba1c68de | 183 | ** Make the Custom themes support do useful things. |
3a84ed60 | 184 | |
ba1c68de | 185 | ** Add support for SVG (Scalable Vector Graphics) rendering to |
296808a5 | 186 | Emacs. |
6add099c | 187 | |
ba1c68de | 188 | ** Allow unknown image types to be rendered via an external program |
d1c3f6b6 RS |
189 | converting them to, say, PBM (in the same way as PostScript?). |
190 | ||
ba1c68de | 191 | ** Allow displaying an X window from an external program in a buffer, |
d1c3f6b6 RS |
192 | e.g. to render graphics from Java applets. [gerd and/or wmperry |
193 | thought this was feasible.] | |
194 | ||
ba1c68de | 195 | ** Allow images (not just text) in the margin to be mouse-sensitive. |
d1c3f6b6 RS |
196 | (Requires recursing through display properties). Provide some way |
197 | to simulate mouse-clicks on marginal text without a mouse. | |
198 | ||
ba1c68de | 199 | ** Implement Lisp functions to determine properly whether a character |
d1c3f6b6 RS |
200 | is displayable (particularly needed in XFree 4, sigh). Use it to |
201 | define useful glyphs that may be displayed as images or unicodes | |
202 | (with ASCIIfied fallback via latin1-disp). Examples include | |
203 | box-drawing graphics in Custom buffers, W3 rules and tables, and | |
204 | tree displays generally, mode-line mail indicator. [See work done | |
205 | already for Emacs 22 and consult fx.] | |
206 | ||
ba1c68de | 207 | ** Do something to make rms happy with fx's dynamic loading, and use it |
d1c3f6b6 RS |
208 | to implement things like auto-loaded buffer parsers and database |
209 | access in cases which need more than Lisp. | |
210 | ||
ba1c68de | 211 | ** Extend ps-print to deal with multiple font sizes, images, and extra |
d1c3f6b6 RS |
212 | encodings. |
213 | ||
ba1c68de | 214 | ** Provide portable undumping using mmap (per gerd design). |
d1c3f6b6 | 215 | |
ba1c68de | 216 | ** Use the XIE X extension, if available, for image display. |
e641b454 | 217 | |
ba1c68de | 218 | ** Make monochrome images display using the foreground and background |
51fe665a RS |
219 | colors of the applicable faces. |
220 | ||
ba1c68de | 221 | ** Add support for rendering antialiased text, probably using |
2a573e69 | 222 | XRender/Freetype. |
c5020b5b | 223 | |
ba1c68de | 224 | ** Port the conservative stack marking code of Emacs' garbage collector |
5e101746 RS |
225 | to more systems, so that we can completely get rid of GCPROs. |
226 | ||
ba1c68de | 227 | ** Reorder defcustom's in each package so that the more important |
5005a9c0 EZ |
228 | options come first in the Customize buffers. This could be done by |
229 | either rearranging the file (since options are shown in the order | |
230 | they appear in the *.el files), or by adding a few :set-after | |
231 | attributes. | |
232 | ||
ba1c68de | 233 | ** Maybe document the features of libraries missing from the manual (or |
5e101746 RS |
234 | ancillary manuals, including the Lisp manual in some cases). |
235 | This is not worth doing for all of these packages and we need not | |
236 | aim for completeness, but some may be worth documenting. | |
237 | ||
238 | Here's a list which is probably not complete/correct: align, allout, | |
239 | artist, ansi-color, array, battery, calculator, cdl, cmuscheme, | |
657c5358 | 240 | completion, cua, delim-col, dirtrack, double, echistory, elide-head, |
5e101746 RS |
241 | easymenu, expand, flow-ctrl, format [format-alist], |
242 | generic/generic-x [various modes], kermit, log-edit, ledit | |
243 | [obsolete?], makesum, midnight [other than in Kill Buffer node], | |
244 | mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile, | |
245 | snmp-mode [?], soundex [should be interactive?], strokes [start from | |
246 | the web page], talk, thingatpt [interactive functions?], type-break, | |
247 | vcursor, xscheme, zone-mode [?], mlconvert [?], iso-cvt, iso-swed, | |
248 | swedish, feedmail [?], uce, bruce, gametree, meese, page-ext, | |
249 | refbib, refer, scribe, sgml-mode, spell, texinfo, underline, | |
250 | cmacexp, hideif, mantemp [obsolete?], pcomplete, assoc, xml, | |
251 | cvs-status (should be described in PCL-CVS manual); other progmodes, | |
252 | probably in separate manual. | |
758830ba | 253 | |
ba1c68de | 254 | ** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap |
bf6394a6 DL |
255 | the XPMs so that the colour versions work generally. (Requires care |
256 | with the colour used for the transparent regions.) | |
257 | ||
ba1c68de | 258 | ** Convenient access to the `values' variable. It would be nice to have an |
758830ba JB |
259 | interface that would show you the printed reps of the elements of the |
260 | list in a menu, let you select one of the values, and put it into some | |
261 | other variable, without changing the value of `values'. | |
bf6394a6 | 262 | |
ba1c68de | 263 | ** Fix skip-chars-{for,back}ward to allow character classes. |
ab5796a9 | 264 | |
ba1c68de | 265 | ** (Controlled by a flag) make open and close syntax match exactly, |
c51b37fd DL |
266 | i.e. `(' doesn't match `]'. |
267 | ||
ba1c68de | 268 | ** Specify parameter ID-FORMAT in all calls to `file-attributes' and |
9ac8c83b LH |
269 | `directory-files-and-attributes' where attributes UID or GID are used. |
270 | Whenever possible, use value 'string. | |
271 | When done, change meaning of default value from 'integer to 'string. | |
272 | If value 'integer is used nowhere, remove the parameter ID-FORMAT from | |
273 | the definition of `file-attributes' and `directory-files-and-attributes' | |
274 | and from the calls. | |
275 | ||
ba1c68de SM |
276 | * Internal changes |
277 | ||
278 | ** Replace gmalloc.c with the modified Doug Lea code from the current | |
279 | GNU libc so that the special mmapping of buffers can be removed -- | |
280 | that apparently loses under Solaris, at least. [fx has mostly done | |
281 | this.] | |
282 | ||
283 | ** Rewrite make-docfile to be clean and maintainable. | |
284 | ||
285 | ** Add an inferior-comint-minor-mode to capture the common set of operations | |
286 | offered by major modes that offer an associated inferior | |
287 | comint-derived mode. I.e. basically make cmuscheme.el generic. | |
288 | For use by sml-mode, python-mode, tex-mode, scheme-mode, ... | |
