21 This file is updated automatically from @file{tasks.texi}, which was
22 last updated on @value{lastupdate}.
25 Check with @code{gnu@@prep.ai.mit.edu}, for a possibly more current copy.
26 This task list is not exclusive; any other useful program might be a
27 good project---but it might instead be something we already have, so
28 check with @code{gnu@@prep} before you start writing it.
32 * Unix-Related Projects::
35 * X Windows Projects::
38 * Games and Recreations::
41 If you start working steadily on a project, please let @code{gnu@@prep}
42 know. We might have information that could help you; we'd also like to
43 send you the GNU coding standards.
45 Because of the natural tendency for most volunteers to write
46 programming tools or programming languages, we have a comparative
47 shortage of applications useful for non-programmer users. Therefore,
48 we ask you to consider writing such a program.
50 In general, a new program that does a completely new job advances the
51 GNU project more than an improvement to an existing program.
54 @chapter Documentation
56 We very urgently need documentation for some parts of the system
57 that already exist or will exist very soon:
61 Completion of the documentation for CC-mode, a new C/C++ mode for
65 A C reference manual. (RMS has written half of one which you could
69 A manual for Ghostscript.
73 @c Ick, do we want to encourage using THAT? -djm
76 A manual for PIC (the graphics formatting language).
82 A book on how GCC works and why various machine descriptions
83 are written as they are.
86 A manual for programming X-window applications.
89 Manuals for various X window managers.
92 Reference cards for those manuals that don't have them: C
93 Compiler, Make, Texinfo, Termcap and maybe the C Library.
96 Many utilities need documentation, including @code{grep} and others.
99 @node Unix-Related Projects
100 @chapter Unix-Related Projects
104 We could use an emulation of Unix @code{spell}, which would run by
105 invoking @code{ispell}.
108 Less urgent: @code{diction}, @code{explain}, @code{style}.
111 An improved version of the POSIX utility @code{pax}. There is one on
112 the Usenet, but it is said to be poorly written. Talk with
113 @code{mib@@gnu.ai.mit.edu} about this project.
117 Modify the GNU @code{dc} program to use the math routines of GNU
122 A @code{grap} preprocessor program for @code{troff}.
125 Various other libraries.
128 An emulation of SCCS that works using RCS.
131 @node Kernel Projects
132 @chapter Kernel-Related Projects
136 An over-the-ethernet debugger stub that will allow the kernel to be
137 debugged from GDB running on another machine.
139 This stub needs its own self-contained implementation of all protocols
140 to be used, since the GNU system will use user processes to implement
141 all but the lowest levels, and the stub won't be able to use those
142 processes. If a simple self-contained implementation of IP and TCP is
143 impractical, it might be necessary to design a new, simple protocol
144 based directly on ethernet. It's not crucial to support high speed or
145 communicating across gateways.
147 It might be possible to use the Mach ethernet driver code, but it would
151 A shared memory X11 server to run under MACH is very desirable. The
152 machine specific parts should be kept well separated.
156 @chapter Extensions to Existing GNU Software
160 Enhance GCC. See files @file{PROJECTS} and @file{PROBLEMS} in the GCC
164 GNU @code{sed} probably needs to be rewritten completely just to make it
168 Work on the partially-implemented C interpreter project.
171 Help with the development of GNUStep, a GNU implementation of the
172 OpenStep specification.
175 Add features to GNU Make to record the precise rule with which each file
176 was last recompiled; then recompile any file if its rule in the makefile
180 Add a few features to GNU @code{diff}, such as handling large input
181 files without reading entire files into core.
184 An @code{nroff} macro package to simplify @code{texi2roff}.
187 A queueing system for the mailer Smail that groups pending work by
188 destination rather than by original message. This makes it possible
189 to schedule retries coherently for each destination. Talk to
190 @code{tron@@veritas.com} about this.
192 Smail also needs a new chief maintainer.
195 Enhanced cross-reference browsing tools. (We now have something at
196 about the level of @code{cxref}.) We also could use something like
197 @code{ctrace}. (Some people are now working on this project.)
200 @node X Windows Projects
201 @chapter X Windows Projects
205 An emulator for Macintosh graphics calls on top of X Windows.
208 A music playing and editing system.
211 A program to edit dance notation (such as labanotation) and display
212 dancers moving on the screen.
215 Port the Vibrant toolkit to work on X without using Motif.
218 A widget for displaying circle-shaped menus ("pie menus") with X
222 A program to display and edit Hypercard stacks.
225 An interface-builder program to make it easy to design graphical
226 interfaces for applications. This could work with the dynamic linker
227 DLD and C++, loading in the same class definitions that will be used
228 by the application program.
231 A "desktop" program with drag-and-drop icons and such.
234 A paint program, supporting both bitmap-oriented operations and
235 component-oriented operations. @code{xpaint} exists, but isn't very
239 A program for manipulating photographs---something vaguely like Photo
240 Shop (though not exactly like it).
244 @chapter Other Projects
246 If you think of others that should be added, please
247 send them to @code{gnu@@prep.ai.mit.edu}.
251 A program to convert compiled programs represented in OSF ANDF
252 (``Architecture Neutral Distribution Format'') into ANSI C.
255 An imitation of Page Maker or Ventura Publisher.
258 An imitation of @code{dbase2} or @code{dbase3} (How dbased!)
261 A program to reformat Fortran programs in a way that is pretty.
264 A bulletin board system. There are a few free ones, but they don't have
265 all the features that people want in such systems. It would make sense
266 to start with an existing one and add the other features.
269 A general ledger program.
272 A program to typeset C code for printing.
273 For ideas on what to do, see the book,
276 Human Factors and Typography for More Readable Programs,
277 Ronald M. Baecker and Aaron Marcus,
278 Addison-Wesley, ISBN 0-201-10745-7
281 (I don't quite agree with a few of the details they propose.)
284 Speech-generation programs (there is a program from Brown U that you
288 Speech-recognition programs (single-speaker, disconnected speech).
291 Scientific mathematical subroutines, including clones of SPSS.
297 Software to replace card catalogues in libraries.
300 Grammar and style checking programs.
303 An implementation of the S language (an interpreted language used for
307 A translator from Scheme to C.
310 Optical character recognition programs; especially if suitable for
311 scanning documents with multiple fonts and capturing font info as well
312 as character codes. Work is being done on this, but more help is needed.
315 A program to scan a line drawing and convert it to Postscript.
318 A program to recognize handwriting.
321 A pen based interface.
324 Software suitable for creating virtual reality user interfaces.
327 CAD software, such as a vague imitation of Autocad.
330 Software for comparing DNA sequences, and finding matches and
335 @chapter Compilers for Other Batch Languages
337 Volunteers are needed to write parsers/front ends for languages such as
338 Algol 60, Algol 68, PL/I, Cobol, or whatever, to be used with the code
339 generation phases of the GNU C compiler. (C++, Objective C and Fortran
340 are done; Ada, Pascal and Java are being worked on.
342 @c Fortran status is here so gnu@prep and the volunteer coordinators
343 @c don't have to answer the question -len
344 You can get the status of the Fortran front end with this command:
347 finger -l fortran@@gnu.ai.mit.edu
350 @node Games and Recreations
351 @chapter Games and Recreations
355 Video-oriented games should work with the X window system.
358 Empire (there is a free version but it needs upgrading)
361 An ``empire builder'' system that makes it easy to write various kinds of
365 Imitations of popular video games:
369 Space war, Asteroids, Pong, Columns.
371 Defending cities from missiles.
373 Plane shoots at lots of other planes, tanks, etc.
375 Wizard fights fanciful monster.
379 Program a robot by sticking building blocks together,
380 then watch it explore a world.
382 Biomorph evolution (as in Scientific American).
384 A program to display effects of moving at relativistic speeds.
388 Intriguing screen-saver programs to make interesting pictures.
389 Other such programs that are simply entertaining to watch.
390 For example, an aquarium.
393 We do not need @code{rogue}, as we have @code{hack}.
