It is compliant with +POSIX.2, except for internationalization features. + +See the file NEWS for a list of major changes in the current release. + +See the file INSTALL for compilation instructions. (The only thing +installed is the documentation; regex.c is compiled into regex.o, but +not installed anywhere.) + +The subdirectory `doc' contains a (programmers') manual for the library. +It's probably out-of-date. Improvements are welcome. + +The subdirectory `test' contains the various tests we've written. + +We know this code is not as fast as it might be. If you have specific +suggestions, profiling results, or other such useful information to +report, please do. + +Emacs 18 is not going use this revised regex (but Emacs 19 will). If +you want to try it with Emacs 18, apply the patch at the end of this +file first. + +Mail bug reports to bug-gnu-utils@prep.ai.mit.edu. + +Please include an actual regular expression that fails (and the syntax +used to compile it); without that, there's no way to reproduce the bug, +so there's no way we can fix it. Even if you include a patch, also +include the regular expression in error; otherwise, we can't know for +sure what you're trying to fix. + +Here is the patch to make this version of regex work with Emacs 18. + +*** ORIG/search.c Tue Jan 8 13:04:55 1991 +--- search.c Sun Jan 5 10:57:00 1992 +*************** +*** 25,26 **** +--- 25,28 ---- + #include "commands.h" ++ ++ #include <sys/types.h> + #include "regex.h" +*************** +*** 477,479 **** + /* really needed. */ +! && *(searchbuf.buffer) == (char) exactn /* first item is "exact match" */ + && searchbuf.buffer[1] + 2 == searchbuf.used) /*first is ONLY item */ +--- 479,482 ---- + /* really needed. */ +! /* first item is "exact match" */ +! && *(searchbuf.buffer) == (char) RE_EXACTN_VALUE + && searchbuf.buffer[1] + 2 == searchbuf.used) /*first is ONLY item */ +*************** +*** 1273,1275 **** + searchbuf.allocated = 100; +! searchbuf.buffer = (char *) malloc (searchbuf.allocated); + searchbuf.fastmap = search_fastmap; +--- 1276,1278 ---- + searchbuf.allocated = 100; +! searchbuf.buffer = (unsigned char *) malloc (searchbuf.allocated); + searchbuf.fastmap = search_fastmap; |
