Does anyone know of Perl-like regular expression parsers written in
Fortran? With the advent of F2003, I imagine we can use the C interop
stuff to achieve the desired effect, but until compilers start
appearing, I was wondering whether there is a F9X solution.
How hard is it to call the C routines from Fortran? CHARACTER
variables might be a little harder than numeric ones.
I would probably write intermediate C programs to do the needed
conversions. It will be implementation specific, but maybe not
too specific. The regex_t pointer is mostly where it can store
some needed information, I believe including a pointer to dynamically
allocated space. A CHARACTER variable of appropriate size should do.
