Subject: [PATCH v3 11/16] ref-filter: introduce refname_atom_parser()
Date: Wed, 30 Mar 2016 15:09:55 +0530 [thread overview]
Message-ID: <1459330800-12525-12-git-send-email-Karthik.188@gmail.com> (raw)
In-Reply-To: <1459330800-12525-1-git-send-email-Karthik.188@gmail.com>
Introduce refname_atom_parser() which will parse the '%(refname)' atom
and store information into the 'used_atom' structure based on the
modifiers used along with the atom.
