Cliprompt

This library provides a simple DSL for managing user interaction in a CLI application. Still under development, but usable already. Check the Changelog to see what is in already.

Features

• manages questions, choices, default values, yes/no values (done)
• makes possible to have env vars set for defaults (done)

Usage

# add in your Gemfile
gem 'cliprompt'

Then in your code

require 'cliprompt'

class Myclass
  extend Cliprompt

  def initialize
    @url = ask "What is the url of Myclass?"
    @ssl = ask "Is it using SSL?", 'y/N'
    @age = ask "What is the age of the captain?", [22,33,=44,55]
    # if you set set ENV['SOMEVAR'], it will override the answer and won't display the question
    # in such case you still can use normal options and nev var will be validated against it (for boolean or choices setup)
    @age = guess 'SOMEVAR', "What is the age of the captain?", [22,33,=44,55]
  end
end

Check example.rb for various possible combinations, or run rspec -f d after all that's also what tests are for.
