Subject: [PATCH 14/15] pretty: introduce get_pretty_userformat
Date: Tue,  9 Jul 2013 16:02:25 +0530	[thread overview]
Message-ID: <1373365946-9230-15-git-send-email-artagnon@gmail.com> (raw)
In-Reply-To: <1373365946-9230-1-git-send-email-artagnon@gmail.com>

This helper function is intended to be used by callers implementing
--pretty themselves; it parses pretty.* configuration variables
recursively and hands the user-defined format back to the caller.  No
builtins are supported, as CMT_FMT_* are really only useful when
displaying commits.  Callers might like to define their own builtins in
the future.
