After spending a lot of time looking at Ruby examples when comparing RIFE to Rails, we realized that we would be better off dropping Java and re-implementing the framework in Ruby completely. The main driving force was that the RoR acronym would both apply to Rife on Ruby and Ruby on Rails. Imagine the productivity gain when only having to use three letters to refer to both projects. We started doing the port about a week ago and already finished 80% of the original functionalities. The whole project took us almost 4 years to write in Java!
Since our 2-man team has released 4 products and 12 sites with RIFE and Java during last year, we didn't want to let those efforts go to waste. We thus also started work on an automated conversion tool that ports old code to the new version. All Java and XML code is translated effortlessly into neat and concise Ruby.
You can look at the current state of our efforts by checking out the subversion repository. Even though we haven't formally released anything yet, we've been using this branch extensively in production for over three days and invite you to do so too!
