Automatic definition of the input dictionary the f_input_file module

In a Fortran program it is often useful to have a high-level handling of the input variables. The Fortran specification provides the namelist approach, which is relatively easy to use. However such an approach presents few drawbacks of portability and code-intrusivity, which limit its usage in a multi-language context. With this module we provide a set of rules to automatically parse, inspect, verify and convert a input file from the yaml format into a futile dictionary. With the usage of the f_input_file module developers might easily write _specifications_ for their program input file.

Such module is in tight connection with its python counterpart, futile.Inputvars, which employs the same conventions and make possible a full interplay between a yaml input file and a python dictionary.

Needed modules

• dictionaries

• yaml_strings (operator(.eqv.)(), f_strcpy())

• f_utils (f_zero())
