How to enable pep8-naming?

[ChenZhongPu]

It seems that ruff adds built-in support of pep8-naming, but it does not give any message in terms of naming conventions for the following code:

def ADD2(a: float, b: float) -> float:
    return a + b


class myabc:
    pass

How to enable pre8-naming?

[ChenZhongPu]

pre-naming belongs to rule N, and it is not enabled by default. We must pass --select N801 to enable it.
