Yet another arguments parser.

Usage

import argumentsParser from '@trenskow/arguments-parser';

const login = async (...args) => {

	const {
		username,
		password
	} = await argumentParser(args).options({
		username: {
			type: String,
			required: true,
			len: '1-',
			description: "Username of the user"
		},
		password: {
			type: String,
			required: true,
			len: '6-',
			description: "Password of the user"
		}
	}, { login });

	// Do login logic.

};

login.description = 'Logs in a user';

const message = async (...args) => {

	const {
		message
	} = await argumentParser(args).options({
		message: {
			type: String,
			default: 'Empty message',
			description: 'Message to send'
		}
	}, { message });

	// Do message logic.

};

message.description = 'Sends a message from a user.';

await argumentsParser(/* argv (default is `process.argv.slice(2)` */)
	.command({ login, message });

The above example will output.
