goluamapper: maps an Azure/golua table to a Go struct

goluamapper provides an easy way to map Azure/golua tables to Go structs.

goluamapper converts an Azure/golua table to map[string]interface{}, and then converts it to a Go struct using mapstructure.

API

See Go doc.

Usage

See the source for the example below.

This example will evaluate a Lua script (as string), extract the resulting person global variable, and map it to our custom Person type:

package main

import (
	"fmt"

	"github.com/Azure/golua/lua"
	"github.com/Azure/golua/std"
	"github.com/jdolitsky/goluamapper"
)

type Person struct {
	Name string
	Age  int
}

func main() {
	state := lua.NewState()
	defer state.Close()
	std.Open(state)

	// Evaluate the Lua script.
	// We can also use state.ExecFile(<filepath>)
	err := state.ExecText(`
		local name = "Fred"
		local age = 42

		person = {
			name = name,
			age = age
		}
	`)
	if err != nil {
		panic(err)
	}

	// Extract the "person" global var and map to Person type
	var person Person
	state.GetGlobal("person")
	err = goluamapper.Map(state.Pop(), &person)
	if err != nil {
		panic(err)
	}

	// Should print "Fred 42"
	fmt.Printf("%s %d\n", person.Name, person.Age)
}
