Contributing

We develop and test this driver using our company internal tools (version control, continuous integration, code review etc.) and automatically synchronize the master branch with GitHub. But this doesn't mean that we don't respond to issues or don't accept pull requests on GitHub. In fact, you're very welcome to open issues or create pull requests :-)

Check coding style

The coding style can be checked with flake8:

pip install -e .[test]  # Install requirements
flake8                  # Run style check

In addition, we check the formatting of files with editorconfig-checker:

pip install editorconfig-checker==2.0.3   # Install requirements
editorconfig-checker                      # Run check
