Ruby Fun!

PipeLine

Create a simple pipeline chaining similar to Unix.

Sample

# Create some pipes
class Upcase < Pipe
  def run
    subject.upcase
  end
end

class Reverse < Pipe
  def run
    subject.reverse
  end
end

class Replace < Pipe
  def run
    subject.to_s.gsub(/(.)/sm, options[:with] || '[\1]')
  end
end

# Run all pipes at once
p = PipeLine("string") | Reverse | Upcase | Replace
p.run
#=> [G][N][I][R][T][S]

# Run all pipes with custom option
p = PipeLine("string") | Reverse | Upcase | Replace(:with => '<\1>')
p.run
#=> <G><N><I><R><T><S>

Jan-Ken-Pon

The classic Rock-Paper-Scissors game.

Sample

ruby jankenpon.rb

or

require "jankenpon"
john = Jankenpon::Player.new(:name => "John", :weapon => :rock)
mary = Jankenpon::Player.new(:name => "Mary", :weapon => :paper)
game = Jankenpon::Game.new

game.play!(john, mary)
game.winner #=> mary
game.status #=> :player2_wins
