Being a mac rails user, I love textmate. Naturally, I went crazy when I found out that Ultraviolet is a syntax highlighting gem for ruby that reads textmate theme and textmate syntax files to create xhtml highlighted code. After using this in my tictactoe project, I integrated it into mephisto. Because I wanted to use the filter:code tag that's normally used by coderay, I did this by deleting all the files in the filtered_column_code_macro/lib plugin except code_macro.rb, which I replaced as follows

require 'uv'
class CodeMacro < FilteredColumn::Macros::Base
  def self.filter(attributes, inner_text = '', text = '')
    lang = attributes.delete(:lang) || "ruby_on_rails"
    theme = attributes.delete(:theme) || "cobalt"
    begin
      Uv.parse( inner_text, "xhtml", lang, false, theme) 
    rescue
        RAILS_DEFAULT_LOGGER.warn "UltraViolet Error: #{$!.message}"
        RAILS_DEFAULT_LOGGER.debug $!.backtrace.join("\n")
    end
  end
end

Then I copied in the xhtml CSS files for Ultraviolet xhtml rendering (as shown in the UV instructions) into my stylesheets directory. I included the themes I liked into my layout.liquid as follows:

<link rel="stylesheet" href="/stylesheets/uv/blackboard.css" type="text/css" media="screen" />
<link rel="stylesheet" href="/stylesheets/uv/dawn.css" type="text/css" media="screen" />
<link rel="stylesheet" href="/stylesheets/uv/cobalt.css" type="text/css" media="screen" />

Finally, you have to remove a reference to 'include "coderay"' in environment.rb. For each code block in your blog, you can change the theme (there's about 12 included themes):

import java.net;

public class Bob extends BobParent implements Bobliness {
  private final int SOMETHING=0;
  public static void main(String[] args) {
    System.out.println("Hello world!" + 5.5)
  }
}
