Fuelcell

Description

Fuelcell is tool for parsing command line arguments & options, allowing you to concentrate more on your application and less on the logic needed to interface with your users through the command line. It handles mapping arguments to executable actions, defining options & arguments, self documenting help system, through a dsl that is small and simple to learn.

Installation

Add this line to your application's Gemfile:

gem 'fuelcell'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fuelcell

Usage

require 'fuelcell'

Fuelcell.start(ARGV.dup) do
  desc 'this is a basic hello world app'
  arg 'name', default: 'World'
  run ->(opts, args, shell) {
    shell.puts "Hello #{args.name}"
  }
end

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
