Node.js parse argument options make ease.

Node.js parse argument options make ease.

Why it's awesome

Rasper transforms command arguments into an easy-to-use formatted object. Flags will be converted into key-value. If there is define flag without value the result will be assumed to be true. Boolean-looking arguments always will be returned as booleans. Numeric-looking arguments always will be returned as numbers. _ contains all arguments that didn't have an flag associated.

Getting Started

Install with npm

$ npm install rasper

Install with Yarn

$ yarn add rasper

Run with npx (without installing)

$ npx rasper

Usage

// cli.js
const argv = require('rasper')
console.dir(argv)

// console
$ pwa-installer dist/**/*.html -f 3 -n -o 4 foo bar baz --manifest --config=pwa.config.js 2 4 -f=99
{
  _: [ 'dist/**/*.html', 'foo', 'bar', 'baz', 2, 4 ],
  n: true,
  o: 4,
  manifest: true,
  config: 'pwa.config.js',
  f: 99
}

Note: If you don't provide an argument process.argv.slice(1) is defined by default.

Arguments containing dashes are not parsed correctly

I've tried using the initify package, however, if I choose a license with a 'dash' the value is not recognized.

Steps to reproduce

initify my-app --license apache-2.0

Expected behavior

{
  _: ['my-app'],
  license: 'apache-2.0'
}

Actual behavior

{
  _: ['my-app'],
  license: 'apache2.0'
}

So the license file is not found.

Default arguments containing the file path execution

Steps to reproduce

$ yarn global add banner-cli
$ banner-cli dist/*.css
#  => { _:
#   [ '/Users/zce/.config/yarn/bin/banner-cli',
#     'dist/zce-design.css' ] }

Expected behavior

process.argv.slice(1)
// => [ <execution file path>, ...other args ]

Actual behavior

process.argv.slice(2)
