flake8-cognitive-complexity's Issues

Plugin is not working on Python <3.7, but this is not mentioned in readme

Python starts from 3.7? Seems, plugin fails on Python 3.6.8 on line:
from __future__ import annotations
Is it possible to add information about requirements in readme?

Add config option max-cognitive-complexity

In addition to the existing cli option, would it be possible to add or document a configuration option?

Project still alive?

Hi,

just a simple question: Is this project still alive? I asking, since there are 6 open issues w/ no comments by the maintainer. Also there was no commit since 2 years and no release since 3 years.

Add autorelease to PyPI on tag push

Add python 3.9 support

cognitive complexity calculation is incorrect

Computed Cognitive complexity is 12 (I believe correct) for this:

class GildedRose:
    def update_quality(self):
        for item in self.items:  # + 1
            if (
                item.name != "Aged Brie"
                and item.name != "Backstage passes to a TAFKAL80ETC concert"
             ):  # + 2
             if item.quality > 0:  # + 3
                 if item.name != "Sulfuras, Hand of Ragnaros":  # + 4
                     item.quality = item.quality - 1
            else:
                pass

However, 10 is incorrect (less than before???) for following code:
Note complexity should be higher than before since code is the same with an added 'if' condition after the 'else'):

class GildedRose:
    def update_quality(self):
        for item in self.items:  # + 1
            if (
                item.name != "Aged Brie"
                and item.name != "Backstage passes to a TAFKAL80ETC concert"
             ):  # + 2
             if item.quality > 0:  # + 3
                 if item.name != "Sulfuras, Hand of Ragnaros":  # + 4
                     item.quality = item.quality - 1
            else:
                #pass
                if item.quality < 50:  # + 3
                    item.quality = item.quality

Add a LICENSE

Hi!

We're looking to use your plugin, but I noticed this repo is not fully licensed (only MIT marker in setup.py) as opposed to https://github.com/best-doctor/flake8-expression-complexity.

Could you add the MIT license to this repo and make a new release?

Thanks in advance,

David
