Creating HTML tags

ruby-talk
1

I would like to be able to use the HTML generation methods from the
cgi library without instantiating a new CGI. Can I do this?

I’ve tried saying include CGI::HtmlExtension

require ‘cgi’

class Thing
include CGI::HtmlExtension
def initialize
puts blockquote() {“hello”}
end
end

but I get cgi.rb:1382:in blockquote': super: no superclass method blockquote’ (NoMethodError)

~/eg/ruby > cat cgiext.rb
require ‘cgi’

class Thing
def initialize type = ‘html3’
case type
when “html3”
extend CGI::Html3
element_init()
extend CGI::HtmlExtension
when “html4”
extend CGI::Html4
element_init()
extend CGI::HtmlExtension
when “html4Tr”
extend CGI::Html4Tr
element_init()
extend CGI::HtmlExtension
when “html4Fr”
extend CGI::Html4Tr
element_init()
extend CGI::Html4Fr
element_init()
extend CGI::HtmlExtension
else
raise ArgumentError, type.to_s
end
puts blockquote() {“hello”}
end
end

Thing.new

~/eg/ruby > ruby cgiext.rb

hello

-a

understand well enough to explain to a computer.
Art is everything else.
