# This program illustrates the basic use of the SimpleMarkup
# class. It extracts the first comment block from the
# simple_markup.rb file and converts it into HTML on
# standard output. Run it using
#
# % ruby sample.rb
#
# You should be in the sample/rdoc/markup/ directory when you do this,
# as it hardwires the path to the files it needs to require.
# This isn't necessary in the code you write once you've
# installed the package.
#
# For a better way of formatting code comment blocks (and more)
# see the rdoc package.
#
require 'rdoc/markup/simple_markup'
require 'rdoc/markup/simple_markup/to_html'
# Extract the comment block from the source file
input_string = ""
File.foreach("../../../lib/rdoc/markup/simple_markup.rb") do |line|
break unless line.gsub!(/^\# ?/, '')
input_string << line
end
# Create a markup object
markup = SM::SimpleMarkup.new
# Attach it to an HTML formatter
h = SM::ToHtml.new
# And convert out comment block to html. Wrap it a body
# tag pair to let browsers view it
puts "<html><body>"
puts markup.convert(input_string, h)
puts "</body></html>"
