fortran_pcre

A very basic wrapper around the PCRE regex C library. Use at your own risk! MIT licence.

This contains the absolute bare minimum to be the least bit useful:

• pcre_compile: to compile a regex
• pcre_exec: to match a regex
• pcre_fullinfo: to get info on a match
• a bunch of constants to pass to pcre_fullinfo

test.f90 is basically a minimal port of pcredemo.c

test3.f90 runs a whole bunch of regex tests

• Compile test like: gfortran-7 -g -std=f2008 pcre_constants.f90 pcre_module.f90 test3.f90 -o test3 -lpcre

Requirements

• libpcre1
• Fortran compiler with decent F2008 support
  • Tested with gfortran 5.4.1, 6.2.1, 7.0.1

Bugs/gotchas

• some character classes like \s and \d don't work. No idea why. Fixed
• super minimal functionality at the mo

TODO

Pull requests more than welcome!

• wrap the rest of the API
• add module for passing strings between C/Fortran
• add the rest of the constants/hex flags
• move constants into separate module
• add tests!
• make object-oriented?
• add CMake support
