Disable too-few-public-methods for attrs.

[benjamin-kirkbride]

Is your feature request related to a problem? Please describe

Dataclasses, and some similar types of classes disable the too-few-public-methods check, but attrs does not. In addition there is not any way to specify types of classes to automatically ignored for those types of checks.

Describe the solution you'd like

Attrs should probably by default disable too-few-public-methods.

Another potential option is to allow the user to specify decorators in the pylintcr that should disable certain checks.

Additional context

I def could just be dumb and unaware of the solution to this problem, but I did google around a lot, and read through design_analysis.py to no avail.

Hey @Beefy-Swain Thanks for the report, this now should be fixed in master.

The error still exists with pylint version 2.17.0 and attrs version 23.1.0

Code:

""" Module description. """

from attrs import define, field, frozen
from attrs.validators import instance_of


@define
class Bar:
    """ Class description. """
    field: int = field(validator=instance_of(int))


@frozen
class Foo:
    """ Class description. """
    field: int = field(validator=instance_of(int))


print(Bar(5))
print(Foo(7))

Output:

************* Module test
test.py:8:0: R0903: Too few public methods (0/2) (too-few-public-methods)
test.py:14:0: R0903: Too few public methods (0/2) (too-few-public-methods)
