astropy.extern.configobj.configobj:InterpolationEngine._parse_match

Extended Summary

Will be passed a match object corresponding to the interpolation key we just found (e.g., "%(foo)s" or "$foo"). Should look up that key in the appropriate config file section (using the _fetch() helper function) and return a 3-tuple: (key, value, section)

key is the name of the key we're looking for value is the value found for that key section is a reference to the section where it was found

key and section should be None if no further interpolation should be performed on the resulting value (e.g., if we interpolated "$$" and returned "$").
