cape.pyfun.options.util: Utilities for pyFun options module

This module provides tools to read, access, modify, and write settings for cape.pyfun. It is based off of the cape.cfdx.options.util module and provides a special class cape.cfdx.options.odict that is subclassed from the Python built-in dict. Behavior, such as opts['Namelist'] or opts.get('Namelist') are also present. In addition, many convenience methods such as opts.get_FUN3DNamelist() are provided.

In addition, this module controls default values of each pyFun parameter in a three-step process. The precedence used to determine what the value of a given parameter should be is below.

  1. Values directly specified in the input file, pyFun.json

  2. Values specified in the default control file, $PYKES/settings/pyFun.default.json

  3. Hard-coded defaults from this module
