vargs 0.5

A simple argument parsing library for V. Ported from this file which was originally written on Typescript.

The version of this module will remain in 0.x.x unless the language API's are finalized and implemented.

// dummy.v
import vargs // or import nedpals.vargs for vpm users
import os

fn main() {
    // Second argument removes the first argument which contains the path of the executable.
    mut _args := vargs.new(os.args, 1)
    
    // Use the `alias` method if you want to map an option to an existing option.
    _args.alias('W', 'with')

    // Parsing is now a separate step
    _args.parse()

    println(_args.str())
    println(_args.command)
    println(_args.unknown[0])
    println('with? ' + _args.options['with'])
}

./dummy cook chicken --with love -W soul
# { command: "cook", options: {"with" => "love"}, unknown: ["chicken"] }
# cook
# chicken
# with? love,soul
