Codebreaker

Codebreaker is a logic game in which a code-breaker tries to break a secret code created by a code-maker. The code-maker, which will be played by the application we’re going to write, creates a secret code of four numbers between 1 and 6.

The code-breaker then gets some number of chances to break the code. In each turn, the code-breaker makes a guess of four numbers. The code-maker then marks the guess with up to four + and - signs.

A + indicates an exact match: one of the numbers in the guess is the same as one of the numbers in the secret code and in the same position.

A - indicates a number match: one of the numbers in the guess is the same as one of the numbers in the secret code but in a different position.

Installation

Add this line to your application's Gemfile:

gem 'codebreaker'

And then execute:

$ bundle

Or install it yourself as:

$ gem install codebreaker

Usage

require_relative 'codebreaker'
require_relative 'codebreaker/ui'
# User Interface for testing CogeBreaker module
module UI
  game = Codebreaker::Game.new
  result = ''
  @name = false
  UI.help

  loop do
    @name = UI.name unless @name
    UI.start if game.start

    loop do
      user_option = UI.capture_guess(game)
      p game.hint if %w[h help hint].include? user_option
      next if user_option !~ /^[1-6]{4}$/
      p result = game.compare_with(user_option)
      break if game.attempts.zero? || result == '++++'
    end

    result == '++++' ? UI.won(@name, game.attempts) : UI.lost
    game.save(@name) if UI.save?
    break unless UI.repeat_game?
  end
  UI.bye
  UI.show(game.score)
end
