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/
The benchmarks bm_regex_effbot.py and bm_regex_v8.py both perform
multiple runs of the tests multiple times, giving just the total times
for each set. Here are the averages:
Python26
BENCHMARK re regex ratio
bm_regex_effbot 0.135secs 0.083secs 1.63
bm_regex_v8 0.153secs 0.085secs 1.80
Python31
BENCHMARK re regex ratio
bm_regex_effbot 0.138secs 0.083secs 1.66
bm_regex_v8 0.170secs 0.091secs 1.87
