That's nice. I suggest that if the OP wants to use your suggested method, maybe do it this w
ay:


class MyHtml
  def self.generate(&block)
    "<html> \n" +
    self.new.instance_eval(&block) +
    "\n</html> "
    end
  def body

    
"<body> \n#{ yield }\n</body>"
  end

  def h1
    
"<h1> #{ yield }</h1>"

  end
end

MyHtml.generate do
  body do
    h1 { "This heading was generated by pure ruby" }
  end
end


Or just use builder or something :P (though it seems like that just might not be allowed for
 the OP, as I suspect whoever is assigning this work expects a real html generator implement
ation.
