add a blueprintcss-based 'to_html' method to Ruby's Array

gistfile1.rb

class Array
  # wrap elements in blueprintcss-oriented div tags
  # ex. results.to_blueprint_html('span', 2, 10, 4, 8)
  def to_blueprint_html(css_class, *args)
    raise ArgumentError, "args count doesn't match number of elements" if args.size != self.size
    output = []
    each_with_index do |item, index|
      output << "<div class='#{css_class}-#{args[index]}'>#{item}</div>"
    end
    output.last.gsub!(/'>/, " last'>") # last element should have 'last' class assigned
    output.join("\n")
  end
end
