M_process

Name

M_process - read and write lines to or from a process from Fortran via a C wrapper

Description

The M_process Fortran module ( A fortran-lang.org package ) reads and writes from processes by calling the C popen(3c) procedure.

NB. These procedures require a platform that supports POSIX routines and the popen(3c) procedure in particular.

Download and Build using make(1)

Just download the github repository, enter the src/ directory and run make:

     git clone https://github.com/urbanjost/M_process.git
     cd M_process/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

     # optionally
     make test               # run the unit tests (needs M_framework(3f) module)
     make run  --example "*" # run all the demo programs from the man-pages
     make help               # see other developer options

This will compile the M_process module and optionally build all the example programs from the document pages in the example/ sub-directory and run the unit tests.

Supports FPM

(registered at the fpm(1) registry )

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

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

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

Demo Programs

The man-pages contain small sample programs that have been extracted and placed in the example/ directory.
