wxWindows regex
|
|
----------------
|
|
This is a version of Henry Spencer's regex,
|
|
which was taken from postresql, which was
|
|
taken from the source of TCL (Toolkit Command Language).
|
|
|
|
This is version of Henry Spencer's library is
|
|
modified by the wxWindows team. The modifications
|
|
made by the wxWindows team are as follows:
|
|
regcustom.h (all source code)
|
|
regex.h (function wrappers, other)
|
|
regc_locale.c (A function or two).
|
|
All the rest (Using standard c library routines instead of
|
|
postresql routines, various cleanup/optimizations)
|
|
|
|
The source code that is wxWindows-specific is as follows:
|
|
regcustom.h (all source code, see comments in source on how to replace)
|
|
regex.h (where noted with comments in source, compiler workarounds)
|
|
regcomp.c (a few of the functions prefixed with wx_,
|
|
these may be replaced by c library routines)
|
|
|
|
This newer library was chosen over the old one because
|
|
Henry Spencer's old library did not support unicode and
|
|
had some other bugs that were fixed by this one, and
|
|
the license was incompatible with the wxWindows license
|
|
and the gpl.
|
|
|
|
Regular Expression syntax documentation is in re_syntax.n.
|
|
Programming information (from older regex, but with
|
|
the function wrappers implemented in the wxWindows
|
|
version, the usage is somewhat the same) is in regex.3.
|
|
|
|
Modifications made by the wxWindows team are not licensed.

|
installation notes:
|
|
--------
|
|
Read the comments at the beginning of Makefile before running.
|
|
|
|
Utils.h contains some things that just might have to be modified on
|
|
some systems, as well as a nested include (ugh) of <assert.h>.
|
|
|
|
The "fake" directory contains quick-and-dirty fakes for some header
|
|
files and routines that old systems may not have. Note also that
|
|
-DUSEBCOPY will make utils.h substitute bcopy() for memmove().
|
|
|
|
After that, "make r" will build regcomp.o, regexec.o, regfree.o,
|
|
and regerror.o (the actual routines), bundle them together into a test
|
|
program, and run regression tests on them. No output is good output.
|
|
|
|
"make lib" builds just the .o files for the actual routines (when
|
|
you're happy with testing and have adjusted CFLAGS for production),
|
|
and puts them together into libregex.a. You can pick up either the
|
|
library or *.o ("make lib" makes sure there are no other .o files left
|
|
around to confuse things).
|
|
|
|
Main.c, debug.c, split.c are used for regression testing but are not part
|
|
of the RE routines themselves.
|
|
|
|
Regex.h goes in /usr/include. All other .h files are internal only.
