contextlib2 is a backport of the standard library's contextlib module to earlier Python versions.
It also serves as a real world proving ground for possible future enhancements to the standard library version.
contextlib2 has no runtime dependencies, but requires unittest2 for testing
on Python 2.x.
Local testing is just a matter of running python test_contextlib2.py.
You can test against multiple versions of Python with tox:
pip install tox tox
Versions currently tested in both tox and Travis CI are:
- CPython 2.6
- CPython 2.7
- CPython 3.4
- CPython 3.5
- CPython 3.6 (CPython development branch)
- PyPy
tox also has a PyPy3 configuration, but it is not configured in Travis due to a known incompatibility.
To install several of the relevant runtimes on Fedora 23:
sudo dnf install python python3 pypy pypy3 sudo dnf copr enable -y mstuchli/Python3.5 sudo dnf install python35-python3
