// Example: How to add builtins to the framework
// Just write a Go function and register it - that's all!

package main

import "fmt"

// Simple function - just register it!
func multiply(a, b int) int {
	return a * b
}

// Function returning multiple values with error
func divide(a, b int) (int, error) {
	if b == 0 {
		return 0, fmt.Errorf("cannot divide by zero")
	}
	return a / b, nil
}

// Complex example with struct
type User struct {
	Name  string
	Email string
	Age   int
}

func getUser(id int) (User, error) {
	return User{
		Name:  "John Doe",
		Email: "john@example.com",
		Age:   30,
	}, nil
}

// Register all builtins in init
// func init() {
// 	RegisterBuiltin("multiply", multiply)
// 	RegisterBuiltin("divide", divide)
// 	RegisterBuiltin("getUser", getUser)
// }

// That's it! TypeScript definitions are auto-generated:
// declare function multiply(arg0: number, arg1: number): number;
// declare function divide(arg0: number, arg1: number): number;
// declare function getUser(arg0: number): any;
