	"github.com/spy16/canister/embedlua"
)

const sampleLua = `
function sayHelloWorld(name)
  fmt_printf("'Hello %s' from Lua using fmt.Printf() of Go!", name)
  return 10
end
`

func main() {
	wr := embedlua.New()
	wr.Bind("fmt_printf", func(format string, args ...interface{}) {
		format = strings.Trim(format, "\n") + "\n"
		fmt.Printf(format, args...)
	})
	wr.BindAll(map[string]interface{}{
		"e":   math.E,
		"Pi":  math.Pi,
		"Phi": math.Phi,
	})
	wr.Execute(sampleLua)

	fmt.Println(wr.Call("sayHelloWorld", "John"))
