Bump flake8-annotations from 2.5.0 to 2.6.0

[dependabot]

Bumps flake8-annotations from 2.5.0 to 2.6.0.

Release notes

Sourced from flake8-annotations's releases.

Release v2.6.0

Changelog

[v2.6.0]

Added

• #98 Add --dispatch-decorators to support suppression of all errors from functions decorated by decorators such as functools.singledispatch and functools.singledispatchmethod.
• #99 Add --overload-decorators to support generic aliasing of the typing.overload decorator.

Fixed

• #106 Fix incorrect parsing of multiline docstrings with less than two lines of content, causing incorrect line numbers for yielded errors in Python versions prior to 3.8

Additional Details

Generic Functions

Per #98, the functools.singledispatch and functools.singledispatchmethod decorators transform a function into a single-dispatch generic function.

For example:

import functools
@​functools.singledispatch
def foo(a):
print(a)
@​foo.register
def _(a: list) -> None:
for idx, thing in enumerate(a):
print(idx, thing)

Is correctly annotated but would previously yield linting errors for foo. In the spirit of the purpose of these decorators, linting errors are now suppressed for functions decorated with these decorators. The --dispatch-decorators configuration option has been added, which specifies a comma-separated list of decorators to be considered as dispatch decorators.

Decorators are matched based on their attribute name. For example, "singledispatch" will match any of the following:

• import functools; @functools.singledispatch
• import functools as fnctls; @fnctls.singledispatch
• from functools import singledispatch; @singledispatch

By default, linting errors are suppressed for functions decorated by singledispatch or singledispatchmethod.

typing.overload decorator aliasing

Per #99, handling of the typing.overload has been made generic, removing the caveat from the initial implementation. The --overload-decorators configuration option has been added, which specifies a comma-separated list of decorators to be considered as typing.overload decorators.

Decorators are now matched based on their attribute name. For example, "overload" will match any of the following:

• import typing; @typing.overload
• import typing as t; @t.overload
• from typing import overload; @overload

By default, linting errors are suppressed for functions decorated by overload, which should be a transparent change from v2.4 (#97).
