I use Tox to run unit tests, with a flake8 command that checks for code formatting errors. Each time I code in PyCharm, I run tox then realise I have a bunch of annoying formatting errors I have to back and manually fix. I would like PyCharm to automatically format the code (according to flake8 google for me each time it auto-saves after I stop typing.
my tox testenv looks like this:
[testenv:flake8] commands=flake8 <my_code_directory> deps = flake8==2.4.1 flake8-import-order==0.11 pep8-naming==0.4.1 [flake8] max-line-length = 120 import-order-style = google Is this possible? Do I have to download a specific plugin somewhere? If not with flake8, what about just PEP-8?

Flake8 interacts with the formatter in two ways: It creates the formatter and provides it the options parsed from the configuration files and command-line It uses the instance of the formatter and calls handle with the error. By default flake8.formatting.base.BaseFormatter.handle () simply calls the format method and then write.

Flake8 and import ordering are not auto-fixable in a way that complies with what you're seeing. You can auto-fix pep8 with autopep8.
There are discussions here about implementing this for Flake8 though.
