How to run a lua script?

Help
1

This is a raw noob question: I wanna run this script from icons-brew.yazi in my terminal

I do

nix-shell -p lua

and then

lua brew.lua

The output is

lua: brew.lua:4: module 'prepare' not found:
	no field package.preload['prepare']
	no file '/nix/store/0mzvskmmy5ffkfz5k8zdnq18pr6vyl1h-lua-5.2.4/share/lua/5.2/prepare.lua'

nix-shell -p lua5_3 works, maybe loading something/init.lua is a feature added in lua 5.3

edit: yeah "./?/init.lua" added to default path · lua/lua@1245989 · GitHub

maybe not related but worth sharing IMO: different lua versions have different default LUA_PATH: those are tested here nixpkgs/pkgs/development/interpreters/lua-5/tests/default.nix at 9760b1436cbd78e69459476e3737e374260f13dd · NixOS/nixpkgs · GitHub
