Incorrect type annotation for Union

[hugary1995]

I got something like

Number: typing._UnionGenericAlias  # value = typing.Union[int, float, bool]

where I expect the correct annotation to be either

Number = typing.Union[int, float, bool]

or PEP 613-style:

Number: TypeAlias = int | float | bool

I'm using version 2.5.5.

Please let me know if I was doing something wrong, or point me to the relevant source code so that I can make a PR. Thanks!

Hi @hugary1995 , can you please include a self-contained full example, i.e., including your pybind11 code that causes this and the call to stubgen (incl. options) that you set?

[hugary1995]

Sure thing. Here it is: https://github.com/hugary1995/pybind11-stubgen-bug

That was my first time trying claude code, pretty interesting.

Hi @hugary1995 , the link does unfortunately not resolve for me. Is that repo public?

[hugary1995]

My bad. I just made it public.
