Re: [PATCH v9 03/20] ref-filter: implement %(if:equals=<string>) and %(if:notequals=<string>)

Karthik Nayak [off-list ref] writes:

This is done by introducing 'if_atom_parser()' which parses the given
%(if) atom and then stores the data in used_atom which is later passed
on to the used_atom of the %(then) atom, so that it can do the required
comparisons.

Add tests and Documentation for the same.
