[GRASS5] regex routines

[David D Gray]

hi all,

One of the shortfalls in writing parsing routines I've found recently is
that there is no native regex handling stuff in GRASS. (is there?). I
considered using the posix librx to provide this, perhaps with useful
wrapper functions that give the handling routines a simpler interface
for users to work with, as the regcomp/regexec etc. business can be a
pain. Does anyone know of any problems with rx, eg unsupported
platforms? If so, are there alternatives that are more acceptable? The
functionality would be very useful where routines have been initially
developed in scripts and have to be moved to C-code to be part of new
modules or library routines.

If it is OK, I would like to propose that this be incorporated into
GRASS 5.1, maybe with the rx library bundled (as it's not standard in
installations even though it is used by many software packages).

David
