From 452db3973c7380808d6e000eff609825e0069105 Mon Sep 17 00:00:00 2001 From: Karthik Nayak Date: Wed, 17 Feb 2016 23:36:18 +0530 Subject: [PATCH] ref-filter: introduce contents_atom_parser() Introduce contents_atom_parser() which will parse the '%(contents)' atom and store information into the 'used_atom' structure based on the modifiers used along with the atom. Also introduce body_atom_parser() and subject_atom_parser() for parsing atoms '%(body)' and '%(subject)' respectively.
