flake8_atlas: add more plugins
Follow up to !22564 (merged). flake8
is a code linter (style checker) for Python. This MR adds a few extra plugins:
- Import OpenStack's
hacking/python23
module - Add
print_for_logging
to check for print statements [disabled by default] - Add
delayed_string_interpolation
plugin - More unit tests and move them to a sub-directory of flake8_atlas
flake8
is used in a few packages as unit test. Beyond that there is no impact.
