Python 3.10 wheels and compatibility about mplcairo HOT 6 CLOSED

As long as a setup.py was present editable install worked with setuptools 61.2.

I did the change for a couple of project I maintain so I though I could offer to do the same here. I will see how it can work with the fiddling needed for that package though.

Sorry for the lack of wheels, I'll make a new release. Most features of mplcairo have still not been moved to matplotlib itself and there are therefore still benefits in using this library (I believe the comparison in the readme should be up to date).
I don't think PEP517 has anything to do with the build problem; rather, the issue is the one at https://github.com/matplotlib/mplcairo#windows: the paths to the cairo and freetype headers and dlls need to be manually specified, as there is no way I can guess where they are available on your system. Instead, use tools/build-windows-wheel.py to build the wheel. (I could consider moving all that logic into setup.py, together with (e.g.) getting freetype.dll from freetype-py instead of having to download it separately, though.)

Thanks for your answer. Let me know if I can help with anything.

mplcairo 0.5 is now on PyPI.
If you want to make things cleaner, you could try moving most of the logic of build_windows_wheel.py into setup.py (together with adding a dependency on freetype-py and getting freetype.dll from them as well, and getting rid of CL/LIBPATH tricks in favor of ext.include_dirs/ext.library_dirs), which would make building on Windows by the normal command invocations work.

I could try to have a look. Would you interested in also making the repo PEP517 compliant ?

Support for editable installs is extremely important for me, and AFAIK PEP517 and editable installs were incompatible until the release of setuptools 64 (a week ago). Now I guess I would be open to moving to a PEP517-type setup, although I have no experience with that and don't really know how it would look like. However, most of the setup logic would likely still remain dynamic (I guess?), so it's not really clear to me what would be the benefits of such a change.
