Cognitive complexity statistic

[ernestasjuska]

Hi,

While looking information on cyclomatic complexity I came across "cognitive complexity".

Info: https://www.sonarsource.com/blog/cognitive-complexity-because-testability-understandability/
Whitepaper: https://www.sonarsource.com/docs/CognitiveComplexity.pdf

It seems to describe complexity of the function better than cyclomatic complexity while remaining very simple.

Maybe this method could be implemented too?

Thanks.

Hi @ernestasjuska. This sounds promising and could be great rule next to the Cyclomatic Complexity (LC0010). I'll will look into this and see if I can make a new rule for this in the undefined future.

For now I've moved your issue to a discussion to have a follow-up here.

@ernestasjuska, The undefined future is here 🙋‍♂️

I wanted to thank you for bringing Cognitive Complexity to my attention. I read the whitepaper back in 2023 and was enthusiastic about it. I didn’t have the experience back then to create this comprehensive rule for it. Over the past years, my knowledge has grown and a recent issue was a challenged and reminder for me to start building a rule for the Cognitive complexity.

It's now available in the v0.34.1 Pre-Release version of the LinterCop if you want to try it out.

Hi, @Arthurvdv,

That is very good to hear. I will tell others to try it too. :)

Are we able to customize the threshold in the LinterCop.json ?

If this is possible it would be useful to have this documented.

@pri-kise, valid question! I've added this to the documentation of the LC0090 rule just a few minuted ago.
