Subject: Re: using heredoc string in erb

I wonder if you could do something along the lines of Rails' capture 
helper? Then you could write

<%= code :brush=>"java" do %>
  Java code goes here
<% end %>

The Java code would still be subject to erb expansion though.

If you're using ERb outside of Rails, you should just be able to copy 
what Rails does.  See 
http://github.com/rails/rails/blob/master/actionpack/lib/action_view/helpers/capture_helper.rb

      # The capture method allows you to extract part of a template into 
a
      # variable. You can then use this variable anywhere in your 
templates or layout.
      #
      # ==== Examples
      # The capture method can be used in ERb templates...
      #
      #   <% @greeting = capture do %>
      #     Welcome to my shiny new web page!  The date and time is
      #     <%= Time.now %>
      #   <% end %>
