---- === EmmyLua ===
----
---- Thie plugin generates EmmyLua annotations for Hammerspoon and any installed Spoons
---- under ~/.hammerspoon/Spoons/EmmyLua.spoon/annotations.
---- Annotations will only be generated if they don't exist yet or are out of date.
----
---- Note: Load this Spoon before any pathwatchers are defined to avoid unintended behaviour (for example multiple reloads when the annotions are created).
----
---- In order to get auto completion in your editor, you need to have one of the following LSP servers properly configured:
---- * [lua-language-server](https://github.com/sumneko/lua-language-server) (recommended)
---- * [EmmyLua-LanguageServer](https://github.com/EmmyLua/EmmyLua-LanguageServer)
----
---- To start using this annotations library, add the annotations folder to your workspace.
---- for lua-languag-server:
----
---- ```json
---- {
----   "Lua.workspace.library": ["/Users/YOUR_USERNAME/.hammerspoon/Spoons/EmmyLua.spoon/annotations"]
---- }
---- ```
