I'm one of the maintainers of Hammerspoon.<p>For some context, this is a fork of an app that's been posted to HN before - Mjolnir. We wanted to take things in a slightly more integrated direction than sdegutis, so we are building on his excellent work and branching out on our own. Massive kudos to him for giving us a solid starting point!<p>Happy to answer questions, here or on #hammerspoon (Freenode), or deal with any github issues you care to file :)
