python 3.11 annotations unsupported. about reloadium HOT 11 CLOSED

I still can't reproduce it but you're right, there is some custom logic around parsing future imports.
I'll have a look into that.

Are you sure you're running it under 3.12? 3.12 is not supported yet.

Whoops, sorry I'm a bit new to pycharm. Looks like I'm running python 3.8 with from __future__ import annotations at the top of my script

from reloadium.

Have been googling for the last hour and haven't found anyone else mention this problem or how to resolve it, any tips?

Correct usage would be:

from typing import Set
buttons: Set[int]

I'm closing this since it's not related to Reloadium

In my opinion this is definitely a bug. I'm using a supported version of python (according to your docs) and I'm getting undesirable behavior due to perfectly acceptable python typing. If this doesn't intend to be supported, perhaps it could be documented somewhere at least?

from typing import Set
buttons: Set[int]

You've shown an example of the old-style annotations,

The annotation style (lowercase set) is perfectly acceptable in python 3.8 if you import from __future__ import annotations at the top of your script.

To add, we have a library of hundreds of python scripts using the future annotation syntax. To my knowledge I don't believe there's a tool that'll auto downgrade to the old style. I know tools like Ruff and pyupgrade will automatically convert to future annotations however.

I see what you mean but I can't reproduce it.

Can you provide a reproducer?

I was struggling to get consistent results, as there didn't seem to be a command to get Reloadium to simply just try to parse a single file. After a bit of experimentation, I finally was able to get it to throw an error in a script consistently, without any non-builtin dependencies.

From what I gather your parser needs to be doing two things:

• Determining if from __future__ import annotations is at the top of the file.
• Ensure Reloadium isn't trying to parse code that's not runtime-available. Check if the errored annotation is in a TYPE_CHECKING block

It might be easier to import something like ruff/pylint to do quick checks like this. Another potential idea is to expose a checkbox in the settings to disable Reloadium's syntax checks. In my scenario, the only thing I want Reloadium to do is reload the changed code/affected modules: I couldn't care less about whether it finds an error in the code.

In the above example, I have the following import structure, compliant with PEP 563

from __future__ import annotations

import contextlib
import os
import pathlib
import re
import subprocess
import sys
import uuid

from tempfile import TemporaryDirectory
from typing import TYPE_CHECKING, Any, Union

from utility.error_handling import format_exception_with_variables

if TYPE_CHECKING:
    from collections.abc import Callable, Generator

    from typing_extensions import Self

from reloadium.

Fixed in Reloadium 1.4.1 and PyCharm plugin 1.4.1
