This the companion code for a series of blog posts starting with part 2 on my ruby blog about proper gem/object contruction using good practices.

The idea here is not mutation, rather a functional deck of cards. You get back an arry and you can do what you like with that array, shuffle, ect.

Currently the cards have "basic" values. The are A:0-K:12. I will be soon showing a way to create a game specific deck of cards using this one as a base using inheritance.... Stay tuned!

Add this line to your application's Gemfile:

gem 'playing_cards'

And then execute:

$ bundle

Or install it yourself as:

$ gem install playing_cards

require 'playing_cards'

# normal 52 card deck
deck = PlayingCards::Deck.new

# many decks for games that require multiple packs of cards
deck = PlayingCards::Deck.new(12)
deck.count #=> 624
