Fails to recognize optional arguments in NamedTuple

[OpenBagTwo]

Summary

NamedTuples with optional / default values still show as "required"

Environment and Version

• Python 3.11.3, running on Linux x86-64
• mkdocs=1.4.3=pyhd8ed1ab_0
• mkdocs-autorefs=0.4.1=pyhd8ed1ab_1
• mkdocs-material=9.1.12=pyhd8ed1ab_0

Steps to Reproduce

Since Python 3.7 (I think?) one can define a NamedTuple with default values as so:

from typing import NamedTuple


class Example(NamedTuple):
    """A simple example of the autorefs bug

    Parameters
    ----------
    required : int
        A required value
    optional : float, optional
        An optional value, default is -3.6
    """

    required: int
    optional: float = -3.6

which behaves as follows:

>>> Example(2)
Example(required=2, optional=-3.6)

Rendering this code with mkdocstrings-python results in the following:

Workaround

Not that I've been able to figure out (besides just not using NamedTuple)

Severity

Annoying.

Desired Outcome

Fix

Urgency

None

Hey, thanks for the report. I've moved it to the Griffe repo and edited the title and body accordingly. Will investigate asap.

Should be fixed, will release soon 🙂
