Subject: Re: using heredoc string in erb

Is this what you need?:

#!/usr/bin/env ruby
require 'erb'
e = ERB.new(DATA.read)
print e.result
__END__
<%= code = <<-CODE.chomp

	// create a panel using a GridBagLayout
	JPanel panel = new JPanel (new GridBagLayout());

	// three labels on the first row
	panel.add (new JLabel ("One"));
	panel.add (new JLabel ("Two"));
	panel.add (new JLabel ("Threeeee"));
CODE
%>
