This is a tool for powerful automation of OS X. At its core, Hammerspoon is just a bridge between the operating system and a Lua scripting engine.

What gives Hammerspoon its power is a set of extensions that expose specific pieces of system functionality, to the user. With these, you can write Lua scripts to control many aspects of your OS X environment.

• Download the latest release
• Drag Hammerspoon.app from your Downloads folder to Applications

• brew install hammerspoon --cask

Out of the box, Hammerspoon does nothing - you will need to create ~/.hammerspoon/init.lua and fill it with useful code. There are several resources which can help you:

• Getting Started Guide
• API docs
• FAQ
• Sample Configurations supplied by various users
• Contribution Guide for developers looking to get involved
• An IRC channel for general chat/support/development (#hammerspoon on Libera)
• Google Group for support

Hammerspoon is a fork of Mjolnir. Mjolnir aims to be a very minimal application, with its extensions hosted externally and managed using a Lua package manager. We wanted to provide a more integrated experience.

Our intentions for Hammerspoon broadly fall into these categories:

• Ever wider coverage of system APIs in Extensions
• Tighter integration between extensions
• Smoother user experience
