glua

embed lua script language for Go

go luajit glue,very very fast, support lua coroutine

Demo

easy use, like:

package main

import (
	"context"
	"fmt"
	"time"

	"github.com/RyouZhang/go-lua"
)

func main() {

	ts := time.Now()
	res, err := glua.NewAction().WithScript(`
	function fib(n)
		if n == 0 then
			return 0
		elseif n == 1 then
			return 1
		end
		return fib(n-1) + fib(n-2)
	end
	`).WithEntrypoint("fib").AddParam(35).Execute(context.Background())

	fmt.Println("cost:", time.Now().Sub(ts))
	fmt.Println(res, err)
}

* fib(35): Fibonacci(35)
* fibt(35): tail-call version of Fibonacci(35)
* Go does not read the source code from file, while all other cases do
