Fortran interface to C POSIX regular expressions

This is a Fortran interface to the POSIX 1003.2 regular expression library using ISO_C_BINDING based on the example in the Fortran wiki.

It adds man-pages and an fpm(1) interface and a unit test.

Volunteers to extend it are welcome

BUILDING THE MODULE USING make(1)

     git clone https://github.com/urbanjost/M_regex.git
     cd M_regex/src
     # change Makefile if not using one of the listed compilers
     
     # for gfortran
     make clean
     make F90=gfortran gfortran
     
     # for ifort
     make clean
     make F90=ifort ifort

     # for nvfortran
     make clean
     make F90=nvfortran nvfortran

This will compile the Fortran module and basic example program that exercise the routine.

BUILD and TEST with FPM

Alternatively, download the github repository and build it with fpm ( as described at Fortran Package Manager )

        git clone https://github.com/urbanjost/M_regex.git
        cd M_regex
        fpm test

or just list it as a dependency in your fpm.toml project file.

        [dependencies]
        M_regex        = { git = "https://github.com/urbanjost/M_regex.git" }
