# ==================== pynogram-web =================== #
futures; python_version < '3.2'
# https://github.com/tornadoweb/tornado/issues/2304
tornado < 5.0                                           # supports long-polling



# =============== optional dependencies =============== #
# numpy's `__copy__` does not work on PyPy, so simply skip it
numpy; platform_python_implementation != 'PyPy'         # fast matrix operations

# or you can install numpy for PyPy like this
# git+https://bitbucket.org/pypy/numpy.git; platform_python_implementation == 'PyPy'



# ======================= tests ======================= #
# it's possible to run tests with simply `setup.py test`
# without cluttering your current virtualenv
# but sometimes it may be convenient to run them another way:

# a) manual invocation
tox                                                     # task management
coverage
flake8                                                  # style checker (PEP8)

# pylint cannot be installed on PyPy3
# because of 'typed-ast' dependency (through 'astroid' dependency)
# https://github.com/PyCQA/astroid/blob/5cc50abb/astroid/__pkginfo__.py#L33
pylint ; platform_python_implementation != 'PyPy' or python_version < '3'


# b) via PyCharm's 'Run Configuration'
pytest >= 3.3                                           # unit test framework
