Using Modules

• A module is some code that can be loaded through the "require" statement
  • Can be a combination of Lua and C code
  • The "require" statement returns a table
  • The table acts as a namespace
  • The table contains constants, functions, etc.
  • The standard libraries are modules

An example of using the math library

local math = require "math" local table1 = {} for i = 1, 10 do table1[i] = math.random(1, 200) print(table1[i]) end

• require cannot pass arguments
  • This restriction is because the structures used are a normal part of the language
  • You can easily create functions in the module that will allow the passing of arguments
