Very simple HTML-Tags in Ruby

tag.rb

class Tag
  def initialize(name, content = nil, **attributes, &block)
    @name = name
    @content = block_given? ? yield : content
    @attributes = attributes
  end

  def to_s
    "<#{@name}#{attributes}>#{@content}</#{@name}>"
  end

  private

  def attributes
    @attributes.map { |k,v| v.nil? ? k : %[#{k}="#{v}"] }.unshift('').join(' ')
  end
end
