Hi  
I’m creating some embedded ruby web pages under Linux and Apache 2.0  
and after showing what it can do I like to display the source code.  
I was wondering if there is an easier way to do this than what I am  
doing at present. An example is where I wish to show the line  
containing  
%\>  
Obviously just trying having a rhtml file with % at the start of a  
line means it is interpreted as ruby code so at present I am using  
% print “%”  
&gt

This works but is a pain. Is there a way to specify to a block of  
code, don’t interpret this code but simple display it in the page it  
came from ?  
TIA  
Paul

Do you mean like this?

```
<html>

  <head>
    <title>Just code</title>
  </head>

  <body>
    <h1>Here is the code</h1>

    <pre><code><%= ERB::Util.html_escape(File.read( __FILE__ )) %>
    </pre></code>

  </body>
</html>

```

Alternatively, if you mean showing it in blocks you’ll have to escape it  
anyway, or the browsers will eat it, won’t they? So just pass them  
through html\_escape.

Alternatively, check out Rote ([http://rote.rubyforge.org](http://rote.rubyforge.org)) for some  
ERB-based ruby-code-macro supporting syntax highlighting fun, where you  
can just do:

```
#:code#ruby
class SomeClass < Other
  def etc(&blk)
    #...
  end
end
#:code#

```

I think ‘\<%%’, and possibly ‘%%\>’, will escape the ‘%’ in rhtml
