In this example the first 10 lines define a Python function that generates a Fortran code snippet to define the dimensions of a variable. The function is used on line 13. Line 13 is in fact the only Fortran code line in this template. Line 12 and 14 form a for-loop that loops over all variables defined in the "variables" dictionary provided by the Python script and holds all variables defined in src/xbeachlibrary/variables.F90. This include file will therefore contain a single line of Fortran code for each variable defined in src/xbeachlibrary/variables.F90. Each line uses the "fortrantype", "rank" and variables "name" from the "variables" dictionary as is visible in line 13. The "rank" is used to generate a Fortran code snippet to define the variables dimensions. Apart from the "variables" dictionary also a "parameters" dictionary is available that holds all parameters from params.F90. Take a look at the other templates in src/xbeachlibrary/templates/ for more examples.
