get_parameters failed for Tuple

[joshmalina]

In Python 3.8, you could:

>>> from typing_inspect import get_parameters
>>> import typing
>>> get_parameters(typing.Tuple)
()

But in Python 3.11, you get:

AttributeError                            Traceback (most recent call last)
File typing_inspect.py:417, in get_parameters(tp)
    416 try:
--> 417     return tp.__parameters__
    418 except Exception as e:

File /usr/local/Cellar/[email protected]/3.11.1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/typing.py:1272, in _BaseGenericAlias.__getattr__(self, attr)
   1271     return getattr(self.__origin__, attr)
-> 1272 raise AttributeError(attr)

AttributeError: __parameters__

During handling of the above exception, another exception occurred:

Exception                                 Traceback (most recent call last)
Cell In[6], line 3
      1 from typing_inspect import get_parameters
      2 import typing
----> 3 get_parameters(typing.Tuple)

File typing_inspect.py:420, in get_parameters(tp)
    418     except Exception as e:
    419         print(tp)
--> 420         raise Exception(e)
    421 else:
    422     return ()

Exception: __parameters__

I'm using version 0.8.0 of the library

PR here: #99

I'm actually seeing this in Python 3.9 as well, so I don't think this is exclusive to 3.11.

[gandersen101]

A little more context, looks like this was fixed in #94 and it was not just an issue about the Tuple type but any non-indexed Generic. However, there does not seem to be a release with the changes from #94 yet. Would it be possible to get one? Thanks!

Hm, it looks like we didn't have a release for a while indeed. I will take a look into making a release soon.

[gandersen101]

That would be great, thank you! @joshmalina, I think this issue and the associated PR can be closed because this is working correctly on master.

FYI I just released https://pypi.org/project/typing-inspect/0.9.0/
