Command-line arguments

Fortran 95 and earlier had no standard support for obtaining command-line arguments. However, with Fortran 2003, several new standard procedures were added to help parse command-line arguments: get_command_argument, get_command, and command_argument_count.

Libraries

• krackenis an open-source library for parsing Unix-like command-line arguments.

• M_CLI use a command prototype to define and read command-line arguments

• f2kcli is an implementation of the Fortran 2003 command line interface for compilers which do not support Fortran 2003.

• getopt_long_module by Joe Krahn.

• getopt.f90 by Mark Gates.

• module options

• CLAF90 is a f90-module for parsing command line arguments.

• FLAP a Fortran command Line Arguments Parser for poor people. A KISS pure Fortran Library for building powerful, easy-to-use, elegant command line interfaces.
