Tools to work with Fortran Namelists and Jobcards

sed

If you want to change GiBUU input jobcards via a (bash) script, one way is to store the skeleton as a template, where the variables you want to change are given by placeholders like XXX. YYY etc. Then you may use sed to replace the placeholder by the actual value, e.g. "sed s/XXX/myValue/"

f90nml, nmltab

Recently (april 2022) I became aware of two projects at GitHub, which are capable of reading in, changing, fine printing, comparing etc. of Fortran jobcards/namelists, written in Python:

• f90nml ​https://github.com/marshallward/f90nml
• nmltab ​https://github.com/aekiss/nmltab
