hello, i’m looking into integrating cython with pants. i’ve seen a couple previous questions in this channel about the topic and wonder if there’s any updates with that. the project currently uses

pyximport

to build the simple library rather than using setuptools - is it possible to configure pants to support this workflow without a custom plugin?

Do you use pyximport at runtime? As outlined here: https://docs.cython.org/en/latest/src/userguide/source_files_and_compilation.html#compiling-with-pyximport If so, Pants is really out of the picture at that point and this should work fine like any other runtime library.

And then you'd use

resource

resources

targets for the

.pyx

files, right?

ah you’re right, worked as soon as i included the pyx files as resources in the BUILD

You may want to define a macro like

cython_sources

that is an alias for creating `resources(name="cython", sources=["*.pyx"])`: https://www.pantsbuild.org/docs/macros

Hey @calm-ambulance-65371 and @modern-wolf-36228, iirc you both are using Cython. I hadn't known about

pyximport

until now and how easy it is to integrate with Pants What do you (and @better-church-90898) think about me adding a "Cython" page to

Python -> Integrations

in our docs focusing on

pyximport

? I think I'm wondering how common it is to use that vs. the setup-py approach

i’m not sure which is more common, but the docs recommend using a setup.py, which is much more powerful and customizable than pyximport
