Building cython extensions using only pyproject.toml (no setup.py)

[rusty-electron]

I am working on a python project that requires the use of cython extension modules. As of now, I am using both a pyproject.toml and a setup.py file. The toml file contains the package metadata, entry points, requirements, etc., and the setup.py only contains the build specifications for the cython file. Because of this, I wanted to know if it is possible to get rid of the setup.py completely and rely only on the pyproject.toml file. I looked up about it on links like this and this but couldn't find an answer. So is it possible to just have a pyproject.toml file and still be able to build the extension modules?

It is current not possible to configure ext_modules in pyproject.toml. For the time being you need both files.

If you're feeling adventurous, check out what I did @ https://github.com/aio-libs/yarl/tree/a3df0aa/packaging. But this is a very non-standard approach that involves monkey-patching, so it's rather dangerous. Do not try at home!

Interesting! I'll take a look.
