Willow Run is a Ruby API to the macOS/OSX airport command providing various wireless utilities. The airport command manages 802.11 interfaces, can perform wireless broadcast scans ( with xml/plist output support ), set arbitrary channels on the interface, and even generate PSKs from specified pass phrases and SSIDs -- all from the command-line, which I really love.
