Could you explain what is for you the difference between your linter the other linters on the same subjects (like gocyclo, funlen, gocognit, ...)?

Otherwise, could you run a go mod tidy

Hi @ldez!

Of course :) Firstly, gocognit calculates cognitive complexity which is something a bit different than cyclomatic complexity.
Secondly, the gocyclo is OK but the author seems to not maintain the project a lot. There were pull requests or issues waiting months to merge/review/answer. This is why I created my own. What's more, it's written in the "old fashion way" without the go/analizer package usage.
The funlen checks the length of the function which's something different than the cyclomatic complexity.

I hope I answered your questions! If you have more, don't hesitate to ask :)

https://github.com/fzipp/gocyclo seems maintained, at least there is a lot of commits in the past year. https://github.com/fzipp/gocyclo/commits/main
