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 | |
6 | it best. Since Emacs is an FSF-copyrighted packages, please be | |
7 | prepared to sign legal papers to transfer the copyright on your work | |
8 | to the FSF. | |

10 | Small but important fixes needed in existing features: | |
a9c1a157 | 11 | |
a9c1a157 RS |
12 | * Make compile.el record the markers that point to error loci |
13 | on text properties in the error message lines. | |
14 | ||
15 | Important features: | |
16 | ||
5e101746 | 17 | * Provide user-friendly ways to list all available font families, |
bf6394a6 DL |
18 | display a font as a sample, etc. [fx is looking at multilingual |
19 | font selection for Emacs 22.] | |
5e101746 | 20 | |
00a18b59 DL |
21 | * Program Enriched mode to read and save in RTF. [Is there actually a |
22 | decent single definition of RTF?] | |
6165b6e3 | 23 | |
a9c1a157 RS |
24 | * Implement something better than the current Refill mode. This |
25 | probably needs some primitive support. | |
26 | ||
27 | * Implement primitive and higher-level functions to allow filling | |
28 | properly with variable-pitch faces. | |
29 | ||
d1c3f6b6 RS |
30 | * Implement a smoother vertical scroll facility, one that allows |
31 | C-v to scroll through a tall image. | |
a9c1a157 | 32 | |
6165b6e3 EZ |
33 | * Implement other text formatting properties. |
34 | ** Footnotes that can appear either in place or at the end of the page. | |
35 | ** text property that says "don't break line in middle of this". | |
36 | Don't break the line between two characters that have the | |
37 | same value of this property. | |
38 | ** Discretionary hyphens that are not visible when they are at end of line. | |
39 | ||
a9c1a157 RS |
40 | * Make movemail work with IMAP. |
41 | ||
bf6394a6 DL |
42 | * Internationalize Emacs's messages. [Note that this is of limited |
43 | use until the menus can display multilingual text. It also doesn't | |
44 | address important issues like using the names of symbols essentially | |
45 | as documentation, e.g. in command names and Custom. -- fx] | |
a9c1a157 | 46 | |
bf6394a6 DL |
47 | * Make the Lucid menu widget display multilingual text. [This |
48 | probably needs to be done from actual Emacs buffers, either directly | |
49 | in the menu or by rendering in an unmapped window and copying the | |
50 | pixels. Note that the relevant Xlib functions assume a specific | |
51 | locale; that isn't good enough even if X can render the arbitrary | |
52 | text, which it often can't as far as I can tell. -- fx] | |
a9c1a157 RS |
53 | |
54 | * Remove the limitation that window and frame widths and heights can | |
55 | be only full columns/lines. | |
56 | ||
657c5358 KS |
57 | * Move fringe to be displayed between display margins and text area. |
58 | [KFS is looking into this]. | |
59 | ||
60 | * Set fringe widths per-window/per-buffer. | |
61 | ||
62 | * Make fringe bitmaps user configurable. Maybe add ability to add | |
63 | additional bitmaps to the fringe from lisp. | |
64 | ||
a9c1a157 RS |
65 | Other features we would like: |
66 | ||
67 | * Have a command suggestion help system that recognizes patterns | |
68 | of commands which could be replaced with a simpler common command. | |
69 | It should not make more than one suggestion per 10 minutes. | |
6165b6e3 | 70 | |
30a2aafd RS |
71 | * Add a way to define input methods by computing them (when first used) |
72 | from other input methods. Then redefine C-x 8 to use a | |
73 | user-selected input method, with the default being the union of | |
74 | latin-1-prefix and latin-1-postfix. | |
75 | ||
a933dad1 DL |
76 | * Implement a clean way to use different major modes for |
77 | different parts of a buffer. | |
78 | ||
79 | * Give start-process the ability to direct standard-error | |
80 | output to a different filter. | |
81 | ||
a933dad1 DL |
82 | * Make desktop.el save the "frame configuration" of Emacs (in some |
83 | useful sense). | |
84 | ||
8ba148c7 RS |
85 | * Give desktop.el a feature to switch between different named |
86 | desktops. | |
87 | ||
a933dad1 | 88 | * Replace finder.el with something that generates an Info file |
e39fc314 DL |
89 | which gives the same information through a menu structure. [Dave |
90 | Love started on this.] | |
a933dad1 | 91 | |
e39fc314 DL |
92 | * Implement a variant of uncompress.el or jka-compr.el that works with |
93 | GNU Privacy Guard for encryption. [Code exists but isn't assigned.] | |
a933dad1 DL |
94 | |
95 | * Save undo information in files, and reload it when needed | |
96 | for undoing. | |
97 | ||
7665519d | 98 | * Merge the Emacs regex.c with the Glibc regex.c. |
bf6394a6 | 99 | They split off a few years ago through negligence. |
7665519d | 100 | |
a933dad1 DL |
101 | * Change the Windows NT menu code |
102 | so that it handles the deep_p argument and avoids | |
103 | regenerating the whole menu bar menu tree except | |
104 | when the user tries to use the menubar. | |
105 | ||
106 | This requires the RIT to forward the WM_INITMENU message to | |
107 | the main thread, and not return from that message until the main | |
0245b3ef | 108 | thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated |
a933dad1 | 109 | the whole menu bar. In the mean time, it should process other messages. |
d054101f | 110 | |
e39fc314 | 111 | * Get some major packages installed: W3/url (development version needs |
a52ce7f8 JB |
112 | significant work), PSGML, Mule-UCS. Check the assignments file for other |
113 | packages which might go in and have been missed. | |
e39fc314 DL |
114 | |
115 | * Make keymaps a first-class Lisp object (this means a rewrite of | |
5dd31b13 SM |
116 | keymap.c). What should it do apart from being opaque ? |
117 | multiple inheritance ? faster where-is ? no more fix_submap_inheritance ? | |
118 | what else ? | |
e39fc314 DL |
119 | |
120 | * Provide real menus on ttys. The MS-DOS implementation can serve as | |
121 | an example how to do part of this. | |
122 | ||
123 | * Implement popular parts of the rest of the CL functions as compiler | |
124 | macros in cl-macs. | |
125 | ||
a52ce7f8 JB |
126 | * Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA, |
127 | but it's a valuable feature worth making more general. | |
e39fc314 DL |
128 | |
129 | * Support simultaneous tty and X frames. | |
130 | ||
bf6394a6 DL |
131 | * Provide MIME support for Rmail using the Gnus MIME library. [Maybe |
132 | not now feasible, given Gnus maintenance decisions. fx looked at | |
133 | this and can say where some of the problems are.] | |
e39fc314 DL |
134 | |
135 | * Eliminate the storm of warnings concerning char/unsigned char | |
136 | mismatches that we get with proprietary compilers on various systems. | |
137 | They make it difficult to spot the important warnings. | |
138 | ||
139 | * Fix anything necessary to use `long long' EMACS_INTs with GCC. | |
eaf67bae DL |
140 | |
141 | * Split out parts of lisp.h and generate Makefile dependencies | |
142 | automatically. | |
143 | ||
144 | * Update the FAQ. | |
145 | ||
b04f7626 DL |
146 | * Allow auto-compression-mode to use zlib calls if zlib is available. |
147 | [It's required for PNG, so may be linked anyhow.] | |
1265b539 DL |
148 | |
149 | * Add a --pristine startup flag which does -q --no-site-file plus | |
150 | ignoring X resources (Doze equivalents?) and most of the | |
151 | environment. What should not be ignored needs consideration. | |
152 | ||
cf56d05f DL |
153 | * Investigate using the language environment (or locale?) to set up |
154 | more things, such as the default Ispell dictionary, calendar | |
6147334f | 155 | holidays, quoting characters?,... |
34f70eda DL |
156 | |
157 | * Improve the GC (generational, incremental). (We may be able to use | |
bf6394a6 | 158 | the Boehm collector.) [fx is working on this.] |
19cc91fb | 159 | |
4dd4cc14 | 160 | * Check what hooks would help Emacspeak -- see the defadvising in W3. |
e2849090 DL |
161 | |
162 | * Implement some variety of (non-gtk) drag-and-drop support under X. | |
52d8e4ff GM |
163 | Using libdnd might be a good start. |
164 | ||
03ff8aab | 165 | * Add horizontal scroll bars. |
00a18b59 | 166 | |
e4ded23c GM |
167 | * Provide an optional feature which computes a scroll bar slider's |
168 | size and its position from lines instead of characters. | |
c0460c17 | 169 | |
bf6394a6 | 170 | * Make the Custom themes support do useful things. |
3a84ed60 | 171 | |
c0460c17 | 172 | * Adapt the gnuserv/gnudoit features for server/emacsclient. |
b09646e3 | 173 | |
8d57a345 | 174 | * Investigate using GNU Lightning or similar system for incremental |
5dcdd840 DL |
175 | compilation of selected bytecode functions to subrs. Converting CCL |
176 | programs to native code is probably the first thing to try, though. | |
b14b5f08 EZ |
177 | |
178 | * Add a feature to Info similar to "info --apropos SUBJECT". | |
8bd6307f | 179 | |
177c0ea7 | 180 | * Add support for SVG (Scalable Vector Graphics) rendering to |
296808a5 | 181 | Emacs. |
6add099c | 182 | |
d1c3f6b6 RS |
183 | * Allow unknown image types to be rendered via an external program |
184 | converting them to, say, PBM (in the same way as PostScript?). | |
185 | ||
186 | * Allow displaying an X window from an external program in a buffer, | |
187 | e.g. to render graphics from Java applets. [gerd and/or wmperry | |
188 | thought this was feasible.] | |
189 | ||
190 | * Allow images (not just text) in the margin to be mouse-sensitive. | |
191 | (Requires recursing through display properties). Provide some way | |
192 | to simulate mouse-clicks on marginal text without a mouse. | |
193 | ||
194 | * Implement Lisp functions to determine properly whether a character | |
195 | is displayable (particularly needed in XFree 4, sigh). Use it to | |
196 | define useful glyphs that may be displayed as images or unicodes | |
197 | (with ASCIIfied fallback via latin1-disp). Examples include | |
198 | box-drawing graphics in Custom buffers, W3 rules and tables, and | |
199 | tree displays generally, mode-line mail indicator. [See work done | |
200 | already for Emacs 22 and consult fx.] | |
201 | ||
202 | * Do something to make rms happy with fx's dynamic loading, and use it | |
203 | to implement things like auto-loaded buffer parsers and database | |
204 | access in cases which need more than Lisp. | |
205 | ||
206 | * Extend ps-print to deal with multiple font sizes, images, and extra | |
207 | encodings. | |
208 | ||
209 | * Provide portable undumping using mmap (per gerd design). | |
210 | ||
211 | * Replace gmalloc.c with the modified Doug Lea code from the current | |
bf6394a6 DL |
212 | GNU libc so that the special mmapping of buffers can be removed -- |
213 | that apparently loses under Solaris, at least. [fx has mostly done | |
214 | this.] | |
d1c3f6b6 | 215 | |
6add099c | 216 | * Use the XIE X extension, if available, for image display. |
e641b454 | 217 | |
2a573e69 CW |
218 | * Add support for rendering antialiased text, probably using |
219 | XRender/Freetype. | |
c5020b5b | 220 | |
d1c3f6b6 | 221 | * Rewrite make-docfile to be clean and maintainable. |
5e101746 RS |
222 | |
223 | * Port the conservative stack marking code of Emacs' garbage collector | |
224 | to more systems, so that we can completely get rid of GCPROs. | |
225 | ||
5005a9c0 EZ |
226 | * Reorder defcustom's in each package so that the more important |
227 | options come first in the Customize buffers. This could be done by | |
228 | either rearranging the file (since options are shown in the order | |
229 | they appear in the *.el files), or by adding a few :set-after | |
230 | attributes. | |
231 | ||
5e101746 RS |
232 | * Maybe document the features of libraries missing from the manual (or |
233 | ancillary manuals, including the Lisp manual in some cases). | |
234 | This is not worth doing for all of these packages and we need not | |
235 | aim for completeness, but some may be worth documenting. | |
236 | ||
237 | Here's a list which is probably not complete/correct: align, allout, | |
238 | artist, ansi-color, array, battery, calculator, cdl, cmuscheme, | |
657c5358 | 239 | completion, cua, delim-col, dirtrack, double, echistory, elide-head, |
5e101746 RS |
240 | easymenu, expand, flow-ctrl, format [format-alist], |
241 | generic/generic-x [various modes], kermit, log-edit, ledit | |
242 | [obsolete?], makesum, midnight [other than in Kill Buffer node], | |
243 | mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile, | |
244 | snmp-mode [?], soundex [should be interactive?], strokes [start from | |
245 | the web page], talk, thingatpt [interactive functions?], type-break, | |
246 | vcursor, xscheme, zone-mode [?], mlconvert [?], iso-cvt, iso-swed, | |
247 | swedish, feedmail [?], uce, bruce, gametree, meese, page-ext, | |
248 | refbib, refer, scribe, sgml-mode, spell, texinfo, underline, | |
249 | cmacexp, hideif, mantemp [obsolete?], pcomplete, assoc, xml, | |
250 | cvs-status (should be described in PCL-CVS manual); other progmodes, | |
251 | probably in separate manual. | |
758830ba | 252 | |
bf6394a6 DL |
253 | * Provide a means to extract image-relative coordinates from mouse |
254 | clicks on images. (Needed for W3, at least.) Also useful for W3 | |
255 | and Gnus: allow images to scroll properly. | |
256 | ||
257 | * Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap | |
258 | the XPMs so that the colour versions work generally. (Requires care | |
259 | with the colour used for the transparent regions.) | |
260 | ||
758830ba JB |
261 | * Convenient access to the `values' variable. It would be nice to have an |
262 | interface that would show you the printed reps of the elements of the | |
263 | list in a menu, let you select one of the values, and put it into some | |
264 | other variable, without changing the value of `values'. | |
bf6394a6 DL |
265 | |
266 | * Fix skip-chars-{for,back}ward to allow character classes. |
