Fortran wrapper around the PCRE library

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
