In the main file.lua:

local calculadora = {
  somar = function(x, y)
    return x + y
  end
}

function calculadora.multiplicar(x, y)
  return x * y
end

return calculadora

In the Copyofmain file.

local calculadora = require("calculadora")

print(calculadora.somar(1, 1))

I put the script on Repl.it. There is also giving error

lua importing

  • I tested here and to get it to work I renamed the file CopyOfmain.lua for calculadora.lua

  • @Code for me keeps giving error, I put the script on the site repl it. and beyond the error

  • @Jeffersonquesado Now I get it. I tested now and it worked! Thank you

  • I put as response the comment, @Gustavogld

For documentation, you pass require("name-of-file").

By calling require "lili", it will search for the following files:

  • lili
  • lili.lua
  • c:\windows\lili
  • /usr/local/lua/lili/lili.lua

In his example, the require is called passing as "calculator" argument, but has no file called calculadora, calculadora.lua or anything of the kind.

Error because you tried to require the function instead of the module, you should do as below:

local Module = require("CopyOfmain")
local calculadora = Module.calculadora

print(calculadora.somar(1, 1))
