Subject: [code-quality] Supplying line numbers to flake8
Message-ID: <CAHHRPYvK+ootqLEGM101DwAiyP8fob-236G55hLj9eEwDtiTzg@mail.gmail.com>

Hello!

I like to use Vim to highlight blocks of code and perform various functions
on them. One thing I have always wanted to do is highlight a block of code
in a large file and run flake8 on just those lines. I have tried to figure
out how flake8 is doing this internally, because it is available through
some kind of interaction with the --diff flag when supplied with a unified
diff. So my questions are,

1) Is there already an invocation syntax I can use to run flake8 on a
certain line # range in a file
2) If not, where can I dig around in the source code to see how --diff does
this?

Thanks a ton, and best wishes!

Subject: [code-quality] Using the pycodestyle API
Message-ID: <2d6452ca-c9c7-40d0-c0dc-2ae5a91b8609@svenbrauch.de>

Hi,

I'm trying to use pycodestyle from a custom script. Importing the
"Checker" class and passing some lines to check works, but how can I
specify which errors to select or ignore? The API docs [1] are a bit
lacking.

Thank you and best regards,
Sven

Hey Sven,

The Checker class isn't really best suited to this use-case. You
really want to be using the StyleGuide object. Also you probably want
to look at the rendered documentation [0]

Cheers,
Ian
