Plugin Handling¶
Plugin Management¶
Flake8 3.0 added support for other plugins besides those which define new checks. It now supports:
extra checks
alternative report formatters
Default Plugins¶
Finally, Flake8 has always provided its own plugin shim for Pyflakes. As
part of that we carry our own shim in-tree and now store that in
flake8.plugins.pyflakes
.
Flake8 also registers plugins for pycodestyle. Each check in pycodestyle
requires different parameters and it cannot easily be shimmed together like
Pyflakes was. As such, plugins have a concept of a “group”. If you look at our
setup.py
you will see that we register pycodestyle checks roughly like
so:
pycodestyle.<check-name> = pycodestyle:<check-name>
We do this to identify that <check-name>>
is part of a group. This also
enables us to special-case how we handle reporting those checks. Instead of
reporting each check in the --version
output, we only report
pycodestyle
once.
