Arg0

It's just here to handle command line args. Mainly optional via switches.

Installation

Add this line to your application's Gemfile:

gem 'arg0'

And then execute:

$ bundle

Or install it yourself as:

$ gem install arg0

Usage

  • to load it up

    require 'arg0'

  • to check if a bool-type switch is provided

    Arg0::Console.switch?('--is-arg') Arg0::Console.switch?(['-isarg', '--is-arg']) # synonymous args

  • returning array of (empty or) Value(s) provided after --my-arg at ARGV

    Arg0::Console.value_for('--my-arg') is same as Arg0::Console.values('--my-arg')

Arg0::Console.value_for(['-myarg', '--my-arg']) # synonymous args
is same as Arg0::Console.values(['-myarg', '--my-arg'])
  • returning the first value (not array of all) for any switch

    Arg0::Console.value('--my-arg') Arg0::Console.value(['-myarg', '--my-arg']) # synonymous args

  • returning Hash for all the Arguments provided as argument on console

    suppose command run was $ arg0_based_cmd -src ./lib -type html -v -l ./log/app.log start

 Arg0::Console.keyring
 # will return {'-src' => './lib', '-type' => 'html', '-v' => true, '-l' => './log/app', 'start' => :data  }
