Is there a way to see the projects this affects using mypy-primer using my mypy branch?

Is there a way to see the projects this affects using mypy-primer using my mypy branch?

The easiest way would be to temporarily push a commit to your mypy PR that makes these edits to mypy/typeshed/stdlib/builtins.pyi

stdlib/builtins.pyi

python/mypy#15687 (comment) changes don't appear to be causing any problems

Is there a way to run this with mypy dev? @srittau

srittau · 2025-10-07T09:57:52Z

@Gobot1234 You could just temporarily change the mypy version in requirements-tests.txt to point to a git reference in this PR I think we did this before, but couldn't find it in git log.

srittau · 2026-01-07T12:58:17Z

I've removed the "deferred" marker.

We might be able to suppress mypy's warnings, although we should add some tests to ensure that mypy still works correctly despite that.

Where do you want these?

You could add a check_bool.py file to this directory: https://github.com/python/typeshed/tree/main/stdlib/%40tests/test_cases/builtins. Docs on how those tests work can be found at https://github.com/python/typeshed/blob/main/tests/REGRESSION.md.
