Subject: [PATCH 07/12] dir.c: refactor is_path_excluded()
Date: Mon, 15 Oct 2012 13:28:01 +0700 [thread overview]
Message-ID: <1350282486-4646-7-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1350282486-4646-1-git-send-email-pclouds@gmail.com>
From: Adam Spiers <git@adamspiers.org>
In a similar way to the previous commit, this extracts a new helper
function last_exclude_matching_path() which return the last
exclude_list element which matched, or NULL if no match was found.
is_path_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.
