#Embedding Lua Scripts in Go with Shopify/go-lua

Welcome Gophers! In this tutorial, we are going to be taking a look at how we can embed Lua scripts in our Go applications.

##Getting Started

You can use the Shopify/go-lua package to embed Lua in Go. Here’s an example of how to do it:

package main

import (
	"fmt"

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


func main() {
	// Create a new Lua state
	l := lua.NewState()
	defer l.Close()

	// Load the standard libraries
	lua.OpenLibraries(l)

	// Load and run a Lua script
	if err := lua.DoFile(l, "script.lua"); err != nil {
		fmt.Println(err)
		return
	}
}

This example loads and runs a Lua script called “script.lua”. You can also execute Lua code directly by using the DoString function:

if err := lua.DoString(l, "print('Hello from Lua')"); err != nil {
	fmt.Println(err)
	return
}

##Conclusion

Embedding Lua in Go provides a powerful way to add scripting capabilities to your applications. The Shopify/go-lua package makes it straightforward to integrate Lua scripts while maintaining the performance benefits of compiled Go code.
