import { question } from "@lou.codes/prompts";
import { createInterface } from "node:readline/promises";

const exampleQuestion = question(
	createInterface({
		input: process.stdin,
		output: process.stdout,
	}),
);

exampleQuestion({
	format: value => parseInt(value, 18),
	query: "How old are you?",
	validate: value => (value < 18 ? "You must be at least 18 years old." : ""),
})
	.then(console.log)
	.catch(console.error)
	.finally(() => readlineInterface.close());

});

exampleQuestion({
	format: value => parseInt(value, 18),
	query: "How old are you?",
	validate: value => (value < 18 ? "You must be at least 18 years old." : ""),
})
	.then(console.log)
	.catch(console.error);
