Hi all,
I re-implemented the re module, adding new features and speed improvements. It's available at:
http://pypi.python.org/pypi/regex
under the name "regex" so that it can be tried alongside "re".
I'd be interested in any comments or feedback. How does it compare with "re" in terms of speed on real-world data? The benchmarks suggest it should be faster, or at worst comparable.
And where are the benchmarks? In particular it would be interesting to see it compared both to re from stdlib and re2 from http://code.google.com/p/re2/
While the re2 comparison might be interesting from an abstract standpoint, it intentionally supports a different regex language from Python so that it can run faster and use less memory. Since re2 can never replace Python's re module, it doesn't make sense to hold MRAB's new module to that standard.
