JRuby on Roller

This is just a quick follow-up to my previous post on Pluggable renderers and scripting languages in Roller. It took me a while, but I finally made JRuby code work inside a Roller page template. Here's an example JRuby page template that displays most recent blog titles and text in HTML format.

$out.println "<html><head>"
$out.println "<title>#{$model.weblog.name}</title>"
$out.println "</head><body>"
$out.println "<h1>#{$model.weblog.name}</h1>"
$model.weblogEntriesPager.entries.keySet().each {|day|
   $model.weblogEntriesPager.entries.get(day).each {|entry|
      $out.println "<h3>#{entry.title}</h3>"
      $out.println "<p>#{entry.text}</p>"
   } 
}
$out.println "</body></html>"
Not the most beautiful thing in the world, I must admit. Any JRuby experts reading along? Is there a simple templating solution that will work in JRuby... something like Groovy Templates? And is there a way to map puts output to a java.io.Writer that will work via BSF?

Pluggable renderers and scripting languages in Roller

My next ApacheCon talk is about Roller and blogs as a web development platform. One of the things I plan to discuss is using scripting languages within Roller, something that's possible now because Roller versions 3.0 and later supports pluggable renderers. It's undocumented and a little hacky right now, but by plugging in your own custom renderers you can add support for new template and scripting languages as alternatives to Roller's built-in Velocity.
