New submission from Eric Promislow <er...@activestate.com>: This regular expression takes a few seconds to be evaluated against any text:
(.*?)((?:X|\s+)*)$ This reg ex is much faster: (.*?)((?:X|\s)*)$ To be fair, Ruby's performance with the first regex is the same as Python's. PHP and JavaScript both fail to match the first regex at all. Only Perl evaluates both regexes nearly instantly. ---------- messages: 150770 nosy: ericp priority: normal severity: normal status: open title: Regular expressions: (?:X|\s+)*$ takes a long time type: performance versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13723> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
