there are 4 ways: - [stylua](https://github.com/JohnnyMorganz/StyLua), can optionally be integrated with emmylua - [LuaLS formatter](https://luals.github.io/wiki/formatter/) - [warr1024's formatter](https://gitlab.com/Warr1024/luatools). it's written in perl. - A simple document. it would be like a guide informing contributors but ultimately ignoreable. i'm leaning towards stylua.
