For more information, see the contribution guidelines on GitHub.īugs found on can be reported on GitHub Where can I get help? They can either be pure Lua scripts that offer useful helper functions, or you can write Objective-C extensions to expose new areas of system functionality to users. More extensions will always be a huge benefit to Hammerspoon. You can learn more about the Lua scripting language at lua.org. 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. How do I install it?ĭownload the latest release and then drag the application to /Applications/. You might want to do something crazy like have iTunes automatically start playing when your Mac detects you are in Paris. You might want to display an alert when your battery drops below a certain percentage. You might want to run a series of commands when your wifi interface connects to your home network. You might want to bind a keyboard shortcut to a series of window operations, or an applescript. Typically you would write a configuration file in Lua that connects events to actions. 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. But anycodings_lua the hammerspoon rotate method that I'm anycodings_lua attempting to call definitely takes a anycodings_lua number, not whatever "userdata" is.This is a tool for powerful automation of macOS. But I anycodings_lua assume that it has to be the new function, anycodings_lua because that's all I changed, and the error anycodings_lua was triggered on attempting to run it. The line numbers, interestingly, in the anycodings_lua traceback are not correct at all: in anycodings_lua config.fnl those lines are comments. In anycodings_lua function anycodings_lua : anycodings_lua in field 'rotate' anycodings_lua /Users/myhomedir/.spacehammer/config.fnl:24: Type 'number' for argument anycodings_lua 1 (expected userdata) stack traceback: 17:24:59: 17:24:59 ERROR: anycodings_lua LuaSkin: hs.timer callbackĮrror: anycodings_lua /Users/myhomedir/.spacehammer/config.fnl:24: anycodings_lua ERROR: incorrect But when I try anycodings_lua to run it, all of a sudden I get errors anycodings_lua coming from c-land: Right? It's your basic lisp translation, it anycodings_lua should work perfectly fine. Then I go to port over my simple preexisting anycodings_lua functions: I translate my lua function into anycodings_lua a Fennel function with a slightly different anycodings_lua name: (fn rotate-vertical So first I get spacehammer working, and anycodings_lua verify that the default configuration works anycodings_lua fine and doesn't throw any errors. Ok, I like lisps, I can handle a anycodings_lua config file in a lisp, right? I anycodings_lua had the following, correctly-working, code anycodings_lua in my a file for hammerspoon to go anycodings_lua get my external monitor and switch it to anycodings_lua vertical: function rotate90()īut then I realized that I wanted to use the anycodings_lua pre-built modal menu toolkit spacehammer, anycodings_lua which is basically like spacemacs for anycodings_lua hammerspoon-but which is written in anycodings_lua Fennel. Caveat: I don't really know lua or fennel, anycodings_lua though I do have a lot of experience in anycodings_lua lua-like languages (python etc.) and anycodings_lua fennel-like languages (clojure, elisp, anycodings_lua etc.).īut: I was using hammerspoon to manage anycodings_lua external monitor configuration on my mac. ![]()
