Subject: [PATCH] menuconfig: regex search + dependencies
Date: Sat, 4 Sep 2004 20:45:12 +0300 [thread overview]
Message-ID: <20040904174512.GA13990@aduva.com> (raw)
Modified the search to go over the properties attached to a symbol (like
Roman suggessted).
Added regex support to help narrow down the searches.
Displaying the parameter's dependencies (nothing fency - simply using
expr_fprint).
Added a 'show_file' helper function.
