main.go

package main

import (
	"fmt"
	plugin "github.com/mafilus/go-lua-plugins"

)

func LuaCanCallMe() string {
	return "Hello World!"
}

func main() {
	plugin.Init()
	defer plugin.Close()

	// Make the function available inside the plugins
	plugin.Set("LuaCanCallMe", LuaCanCallMe)

	p, err := plugin.Load("./myPlugin.lua")

	ret1, err := plugin.Call("myPlugin.HelloWorld")
	
	ret2, err := p.Call("OnSomeEvent")

	var squared int
	err = p.CallUnmarshal(&squared, "Square", 2)

	// Call each loaded plugins "HelloWorld" function
	plugin.Each(func(p plugin.Plugin) {
		if ret, err := p.Call("HelloWorld"); err == nil {
			fmt.Println(ret)
		}
	})

	fmt.Println(ret1, ret2, err)
}

or

package main

import (
	"fmt"
	lua "github.com/mafilus/go-lua-plugins"

)

func LuaCanCallMe() string {
	return "Hello World!"
}

func main() {
	plugin := lua.NewInstance()
	defer plugin.Close()

	// Make the function available inside the plugins
	plugin.Set("LuaCanCallMe", LuaCanCallMe)

	p, err := plugin.Load("./myPlugin.lua")

	ret1, err := plugin.Call("myPlugin.HelloWorld")
	
	ret2, err := p.Call("OnSomeEvent")

	var squared int
	err = p.CallUnmarshal(&squared, "Square", 2)

	// Call each loaded plugins "HelloWorld" function
	plugin.Each(func(p plugin.Plugin) {
		if ret, err := p.Call("HelloWorld"); err == nil {
			fmt.Println(ret)
		}
	})

	fmt.Println(ret1, ret2, err)
}

myPlugin.lua

function HelloWorld()
    return LuaCanCallMe()
end

function OnSomeEvent()
    return "Some event process"
