Lua Require function on a full path name

Question

I need to call the require on a lua file that will not always be in the same place. I was trying to call require on the full path name but that doesn\'t seem to be working e

Answer 1

If you just need to load a file, use dofile, which takes a path:

dofile("C:\\Users\\Me\\MyLuaProject\\foo")

Answer 2

Add the directory containing the file to package.path:

package.path = package.path .. ";C:\\Users\\Me\\MyLuaProject"
require "foo"

You can also add it to the LUA_PATH environment variable, but this is probably less easy to modify on the fly.

A common pattern for modules is to have abc.lua and abc/xyz.lua; to require files in a subdirectory like that, use the following:

require "abc"
require "abc.xyz"
