-- Suppose the file mod.lua looks like this: local M = {} local function sayMyName() print('Hrunkner') end function M.sayHello() print('Why hello there') sayMyName() end return M -- Another file can use mod.lua's functionality: local mod = require('mod') -- Run the file mod.lua. -- require is the standard way to include modules. -- require acts like: (if not cached; see below) local mod = (function () <contents of mod.lua> end)() -- It's like mod.lua is a function body, so that -- locals inside mod.lua are invisible outside it. -- This works because mod here = M in mod.lua: mod.sayHello() -- Says hello to Hrunkner. -- This is wrong; sayMyName only exists in mod.lua: mod.sayMyName() -- error -- require's return values are cached so a file is -- run at most once, even when require'd many times. -- Suppose mod2.lua contains "print('Hi!')". local a = require('mod2') -- Prints Hi! local b = require('mod2') -- Doesn't print; a=b. -- dofile is like require without caching: dofile('mod2.lua') --> Hi! dofile('mod2.lua') --> Hi!
