Project description


flake8 plugin to find commented out (or so called "dead") code.

This is quite important for the project in a long run. This tool is based on eradicate project. Build Status Coverage Python Version PyPI version

Run your flake8 checker as usual. Commented code should raise an error.

We prefer not to raise a warning than to raise a false positive. So, we ignore --aggressive option from eradicate.
