#HAMMERSPOON CAPS LOCK FULL#
If you are new to Hammerspoon, read the Getting Started Guide with reference to the full API documentation. You will need to create a Lua script in ~/.hammerspoon/a using our APIs and standard Lua APIs. Out of the box, Hammerspoon does nothing.
#HAMMERSPOON CAPS LOCK INSTALL#
How do I install it?ĭownload the latest release and then drag the application to /Applications/.

#HAMMERSPOON CAPS LOCK CODE#
The important part of this code is that the moment you press a key other than caps while caps is still depressed, it changes to the ctrl keycode being sent. If you hold it longer than that it turns back into ctrl. Typically you would write a configuration file in Lua that connects events to actions. It shouldn't interfere with anything in normal use, if its an esc press it will almost always be depressed for less than 0.2. If you want to explore the options Hammerspoon offers, check out the Getting Started Guide and the full API documentation as well as the already pre-made plugins called Spoons. You can write Lua code that interacts with macOS APIs for applications, windows, mouse pointers, filesystem objects, audio devices, batteries, screens, low-level keyboard/mouse events, clipboards, location services, wifi, and more. What gives Hammerspoon its power is a set of extensions that expose specific pieces of system functionality, to the user. At its core, Hammerspoon is just a bridge between the operating system and a Lua scripting engine. This is a tool for powerful automation of macOS.
