Hammerspoon

What is Hammerspoon?

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.

How do I install it?

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

What next?

We have a Getting Started Guide, extensive API docs, a FAQ, a Contribution Guide for developers looking to get involved, and an IRC channel for general chat/support/development (#hammerspoon on Freenode).

What is the history of the project?

Hammerspoon is a fork of Mjolnir by Steven Degutis. 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.

What is the future of the project?

Our intentions for Hammerspoon broadly fall into these categories:

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