Description

Optimist is a commandline option parser for Ruby that just gets out of your way. One line of code per option is all you need to write. For that, you get a nice automatically-generated help page, robust option parsing, and sensible defaults for everything you don't specify.

Features

  • Dirt-simple usage.
  • Single file. Throw it in lib/ if you don't want to make it a Rubygem dependency.
  • Sensible defaults. No tweaking necessary, much tweaking possible.
  • Support for long options, short options, subcommands, and automatic type validation and conversion.
  • Automatic help message generation, wrapped to current screen width.

Requirements

  • A burning desire to write less code.

Install

  • gem install optimist

Synopsis

require 'optimist'
opts = Optimist::options do
  opt :monkey, "Use monkey mode"                    # flag --monkey, default false
  opt :name, "Monkey name", :type => :string        # string --name <s>, default nil
  opt :num_limbs, "Number of limbs", :default => 4  # integer --num-limbs <i>, default to 4
end

p opts # a hash: { :monkey=>false, :name=>nil, :num_limbs=>4, :help=>false }
