Can you call “require” on a variable?

问题

I have a lua file that will require another lua file to run but I can't hard code the file name. Can i use the require function on a variable or do i need to figure out an alternate approach to what i am doing?

For example

local path = "mypath.txt"

local level = require path

回答1:

Yes, you can. require "module" is just a syntactic sugar for require("module") that only works if call a function with single argument that is a string or table constructor. Use proper call in form of require(path) and it will work.
