Suggestion for V CLI module usage

vlib-cli-usage-suggestions.v

// Example of creating a CLI app

// Imports

import os
import cli

// Types

type FlagType = string | int | bool | string[] | int[] 
type ArgumentValueType = string | int | bool | string[] | int[]

// == The struct way ==
// Easier to program, but less convenient for the CLI developer (in my opinion)

app := cli.App {
	name: 'My Amazing Program',
	desc: 'An amazing program',
	version: '0.1.0',
}
	
app.commands = [
	cli.Command {
		name: 'order',
		arguments: {
			pizza_type: cli.Argument {
				desc: 'Type of pizza'
				required: true
			}
		},
		flags: {
			small: cli.Flag {
				short: 's', long: 'small'
				desc: 'Order a small pizza',
				required: false,
			}
			large: cli.Flag {
				short: 'l', long: 'large'
				desc: 'Order a large pizza',
				required: false,
			}
		},
		execute: fn (arguments map[string]cli.ArgumentValueType{}, options map[string]cli.FlagType{}) {
			println(`Ordering a $arguments.pizza_type pizza...`)
			println(`Is it small: $options.small`)
			println(`Is it large: $options.large`)
		}
	}
]

app.run(os.args)

// == The functions way ==
// May be a bit more difficult to program, but IMO more convenient for the CLI developer

app := cli.App {}

app.name('My Amazing Program')
