This is for testing: http://web.me.com/jlundell/filechute/template.zip I do not understand one part of the pattern. For example: + r"'(?!'')(?:[^'\\]+|\\.)*'" Why do we need the |\\. ? What function is it serving? It seems to make the alternation useless. Also, I'm not sure why we're escaping the right square bracket. > > >> >> On Apr 7, 7:43 pm, Jonathan Lundell <jlund...@pobox.com> wrote: >>> On Apr 7, 2010, at 2:28 PM, Timothy Farrell wrote: >>> >>>> I've looked at this problem extensively and I'm convinced that the >>>> solution is to re-implement template.py without complicated regexps or >>>> remove the claim of Jython support. >>> >>>> The exact problem is related to the size of a view that is run through the >>>> template module.
