module Corrector

  # Breaks source string to words.
  class Words < Array

    # The source array or string for the current words list.
    #
    # @example:
    #     words = Words.new "М В С2" # => #< Words ["М", "В", "С", "2"]>
    #     words.source # => "М В С2"
    #
    #     words = Wrods.new ["М", "В", "С2"] # => #< Words ["М", "В", "С2"]>
    #     words.source # => ["М", "В", "С2"]
    #
    # Returns either array or string.
    attr_reader :source

    # Initializes the array containing words from the source array or string.
    #
    # @example
    #     Words.new                  # => #<Words []>
    #     Words.new "М В С2"         # => #<Words ["М", "В", "С", "2"]>

    # Returns the array of recognized words from the initial string.
    # Both the +map+ and +to_s+ methods of the array are redefined.

    #
    # Returns the mapped +Words+ object.

    # Converts words list to a string. Joins words divided by the +^+ symbol
    # and removes spaces around the slash.

    # @example
    #     words = Words.new %w(К ^ М / C ^ 2)
    #     words.to_s # => "КМ/С2"
    #
    # Returns a converted string with +source+ method to check the source.
