Subject: [PATCH v3 08/19] dir.c: refactor is_excluded()
Date: Thu, 27 Dec 2012 02:32:27 +0000 [thread overview]
Message-ID: <1356575558-2674-9-git-send-email-git@adamspiers.org> (raw)
In-Reply-To: <1356575558-2674-1-git-send-email-git@adamspiers.org>
In a similar way to the previous commit, this extracts a new helper
function last_exclude_matching() which returns the last exclude_list
element which matched, or NULL if no match was found. is_excluded()
becomes a wrapper around this, and just returns 0 or 1 depending on
whether any matching exclude_list element was found.
This allows callers to find out _why_ a given path was excluded,
rather than just whether it was or not, paving the way for a new git
sub-command which allows users to test their exclude lists from the
command line.
