[Python-Dev] Regexp 2.7

Tue Mar 10 19:08:36 CET 2009

Would there be any interest in augmenting the test case library for 
the regex stuff?
When I was working on PyPy, we were using a simplified regular 
expression matcher to implement the tokenizer for Python. I was able 
to take a lot of PCRE's regex tests and port them to test our regular 
expression implementation (to make sure the DFA's were being optimized 
properly, etc).
I believe the PCRE test library was under a very liberal license, and 
so we may be able to do the same here. If there's interest in it, I 
can do the same for Python.
