It’s a stand-alone Nova extension to use Flake8, a tool to check the style and quality of Python code.
Before using the extension, it’s necessary to install Flake8 itself if you don’t have one already.
Flake8 can be installed simply by running pip install flake8.
The extension supports both global and workspace configurations. A workspace configuration always overrides a global one.
There are three options available to configure: executable path, command arguments,
and check mode. By default, the executable path is /usr/local/bin/flake8, with
no additional arguments, and checking on changing.
You could alter the executable path if Flake8 installed in a different place
or if /usr/bin/env usage is desirable.
In the case of /usr/bin/env, it becomes the executable path, and flake8 becomes
the first argument.
The extension respects .flake8 in a project directory. So, there’s no need to
specify the --config argument explicitly.
