Subject: [PATCH 7/8] wildmatch: make /**/ match zero or more directories
Date: Tue, 9 Oct 2012 10:09:06 +0700 [thread overview]
Message-ID: <1349752147-13314-8-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1349752147-13314-1-git-send-email-pclouds@gmail.com>
"foo/**/bar" matches "foo/x/bar", "foo/x/y/bar"... but not
"foo/bar". We make a special case, when foo/**/ is detected (and
"foo/" part is already matched), try matching "bar" with the rest of
the string.
"Match one or more directories" semantics can be easily achieved using
"foo/*/**/bar".
This also makes "**/foo" match "foo" in addition to "x/foo",
"x/y/foo"..
