TODO file for GNU m4 Tell <bug-m4@gnu.org> if you feel like volunteering for any of these ideas, listed more or less in decreasing order of priority. * Features or problems - Fix format() builtin to handle %c more like printf(1) in the shell http://lists.gnu.org/archive/html/bug-m4/2007-05/msg00047.html Also, gnulib needs help to overcome mingw bugs related to format(). - Update documentation from accumulated mail about it - Study synclines at the very beginning of each diverted sequence - Make eval work on bignums - the 32 bits limit is artificial From Krste Asanovic <krste@icsi.berkeley.edu>, 1993-03-20 * Optimization and clean up - Check for memory leaks and uninitialized reads From Vern Paxson <vern@horse.ee.lbl.gov> on 1993-12-06 - Profile GNU m4 and speed it up From David J. MacKenzie <djm@eng.umd.edu>, 1993-01-20 GNU m4 should be sped up by a factor of three for competing with other versions (I think that the lexer is not agressive enough and too often return single characters; obstacks might be a little abused, too). - Have NULs go really undisturbed through GNU m4 See `dumpdef' and debugging section, which abuses %s From Thorsten Ohl <ohl@chico.harvard.edu>, 1992-12-21 path.c (add_include_directory): Why the '\0' terminator? GNU m4 is lousy regarding NULs in streams (this would require maintaining the string lengths, and avoiding strlen, strcpy, etc.).
