Exception on Ubuntu 14.04 regex

[andreikop]

On Ubuntu 14.04 python-regex version 0.1.20140216-1 is available. With this version I have the following exception:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/enki/lib/future.py", line 480, in onDoneSignal
    future._g(future)

Bryan, could you check if we can leave with this version or should install regex from pip but not from .deb. Even if we can't work on old regex, we should recognize it and avoid exceptions.

Aargh. Old packages are so painful. We definitely need a recent version; prior to 7-Nov-2015, regex had some serious fuzzy matching bugs. To fix this, I'd like to use pkg_resources. Any objections?

import pkg_resources

# The `regex <https://pypi.python.org/pypi/regex>`_ module supports approximate
# matching. Make sure it is recent enough to be usable.
import regex
try:
  # Get the version of regex. See https://pythonhosted.org/setuptools/pkg_resources.html#distribution-attributes.
  regexVersion = pkg_resources.get_distribution('regex').parsed_version
  # Issues I filed before this make regex unusable. See #166, #167, andd #169 at
  # https://bitbucket.org/mrabarnett/mrab-regex/issues. For version parse, see
  # https://pythonhosted.org/setuptools/pkg_resources.html#parsing-utilities.
  assert regexVersion >= pkg_resources.parse_version('2015.11.07')
except AssertionError, ValueError:
  raise ImportError

The fix is merged!
