This does not fix the issue for some reason - even after upgrading mypy and clearing the cache.

Following https://mypy.readthedocs.io/en/stable/installed_packages.html#creating-pep-561-compatible-packages, it might be neccessary to set zip_safe to False.

hm, thats anoying. I will look into this some more...

@phoenixr-codes it should work now, could you please try again? Use:

pip install -U --pre readchar==4.0.4.dev1

Coverage: 94.156%. Remained the same when pulling 6a6bda2 on py-typed into 4a69e22 on master.

Still does not work. The py.typed seems to be excluded during the build.

Going to the site packages

python -c "print(__import__('site').getsitepackages()[0])"

and looking at some library's files, shows that some of them
contain a py.typed file - readchar does not.

I have managed to create a library which mypy recognizes as typed by using this pyproject.toml file:

[build-system]
requires = ["setuptools", "setuptools-scm"]
build-backend = "setuptools.build_meta"

[project]
name = "typing_mypy_test"
version = "0.0.2"

[tool.setuptools.package-data]
typing_mypy_test = ["py.typed"]

[tool.setuptools]
zip-safe = false

# file: main.py
def add(a: float, b: float) -> float:
    return a + b

Directory Structure (after python -m build):

But I made sure that this time the file is included in both the .tar.gz and the wheel, wird.

But thanks for the hints from other packages, I will look how they handle it

Ok I found the problem. My release-pipeline is a bust and actually always releases master, so these changes are not in the pre-release versions... -_-

If you have the time you could try installing directly from the repo, like this:

pip install -U git+https://github.com/magmax/[email protected]

I will fix the pipeline...

@phoenixr-codes The pipeline is fixed and the newest pre-release version now actually containes the changes (also in the versions pushed to pypi). So installing this should work:

pip install -U --pre readchar==4.0.4.dev2
