 go 中使用 lua

package main

import (
	lua "github.com/yuin/gopher-lua"
)

func main() {
	l := lua.NewState()
	defer l.Close()
	if err := l.DoString(`print("Hello World")`); err != nil {
		panic(err)
	}
}

L := lua.NewState()
defer L.Close()
if err := L.DoFile("hello.lua"); err != nil {
    panic(err)
}

lua 中使用 go

mymodule.go

package mymodule

import (
    "github.com/yuin/gopher-lua"
)

func Loader(L *lua.LState) int {
    // register functions to the table
    mod := L.SetFuncs(L.NewTable(), exports)
    // register other stuff
    L.SetField(mod, "name", lua.LString("value"))

    // returns the module
    L.Push(mod)
    return 1
}

var exports = map[string]lua.LGFunction{
    "myfunc": myfunc,
}

func myfunc(L *lua.LState) int {
    return 0
}

mymain.go

package main

import (
    "./mymodule"
    "github.com/yuin/gopher-lua"
)

func main() {
    L := lua.NewState()
    defer L.Close()
    L.PreloadModule("mymodule", mymodule.Loader)
    if err := L.DoFile("main.lua"); err != nil {
        panic(err)
    }
}

main.lua

local m = require("mymodule")
m.myfunc()
print(m.name)
