Jython, Jepp or Pylons for the performance
I'm trying to incorporate server-based code diff and highlighting in my GWT (Java) project. I managed to incorporate Pygments and difflib
If so, what's next? I discover Jepp but then I would have to build my project for each platform and it has little documentation and don't seem very stable. Another possibility would be to run Pylons as a separate webservice on the same host and get the markup directly to client or channel it through server. And yet another way is to use Java System to execute python script as a process and capture the output.
I would be very interested to hear solid suggestion on the matter.
Having a separate service sounds like the best way to go. For Pygments, there is already a service available (on Google App Engine). The source for the app is BSD open source and on GitHub here. You could adapt this to add difflib functionality too, of course.
I'm going to accept answer above since it coincides with my findings but just to let anyone who reads this know - running separate webservice for Pygments using Python-native solution such as Bottle performs many times better than embedded Jython. Especially on Linux
