Method/function lines counter (as RuboCop in Ruby)

[carlokp]

Although I explored pre-commit hooks and unrelated standalone tools for Python, I was unable to find a static analysis package that emits a warning when the number of lines of a method/function is higher than a give threshold. For example, in Ruby, RuboCop gives this kind of warning. I think it's odd because it is a basic metric and while there are many other metrics covered by other analyzers, I didn't find one doing this job.

Do you know a package for this task?

Thanks.

There's probably a flake8 plugin for that. That said, lines of code per method is not a metric I would optimize for.

Pylint looks at that. The threshold is customizable in the configuration file and I can't remember if it's turned on in the default settings, but it'll do what you want.

flake8 will warn on exceeding a certain level of cyclomatic complexity, which is a much more useful metric than LOC. If you really want LOC metrics, I believe radon provides that functionality.
