package main

import lua "github.com/Shopify/go-lua"

func main() {
        l := lua.NewState()
        lua.OpenLibraries(l)
        l.Global("print")
        l.PushString("Hello World!\n")
        l.Call(1, 0)
}

Quick question, if I call DoString on the lua state, how can I retrieve the value of that lua code snippet? It seems the documentation is really lacking in go-lua.

Thanks in advance!
