This should be the same module as in the issue (and thankfully, because code management of such a big project does not belong exclusively in a tracker issue). "mrab" stands for Matthew Barnett, who is the author of regex. > -- > > There is also the re2 library from Google and especially this project: > > http://pypi.python.org/pypi/re2/ > > "pyre2 is a Python extension that wraps Google's RE2 regular expression > library. > > This version of pyre2 is similar to the one you'd find at facebook's > github repository except that the stated goal of *this version is to be > a drop-in replacement for the re module*.)" Well, while it can be called drop-in, it is hardly a good replacement: """ That being said, there are features of the re module that this module may never have. For example, RE2 does not handle lookahead assertions ((?=...)). """ It falls back to old re in these cases.
