Questions about updating the Python build tools for a patch

Hello,

I am working on a patch for an update to python-humanize, but I believe this is going to necessitate updating some packages in python-build. I would appreciate it if someone could give me some advice and let me know if this is even the right thing to be doing.

When trying to build python-humanize@4.11.0 I received the following error:

starting phase `build'

Using 'hatchling.build' to build wheels, auto-detected 'hatchling.build', override '#f'.

Traceback (most recent call last):

File "<string>", line 4, in <module>

File "/gnu/store/iafxd40mzizd2kndvla2inmkmjhnygrr-python-hatchling-1.14.0/lib/python3.10/site-packages/hatchling/build.py", line 56, in build_wheel

ValueError: Unknown classifier in field `project.classifiers`: Programming Language :: Python :: 3.13

I believe this is due to python-hatchling being a little out of date. I updated python-hatchling, however this requires a more recent version of python-packaging. I see that the current package uses python-packaging-bootstrap, which cannot be updated without creating a circular dependency, shown below:

gnu/packages/python.scm:1171:4: error: python-toolchain@3.10.7: dependency cycle detected:

python-toolchain@3.10.7 -> python-packaging-bootstrap@24.1 -> python-pypa-build@0.7.0 -> python-toolchain@3.10.7 -> python-humanize@4.11.0

To resolve this, my plan was to change that dependency to python-packaging and update that package's version. However, when I try to add "#:use-module (gnu packages python-xyz)" like so:

(define-module (gnu packages python-build)

#:use-module (gnu packages)

#:use-module (gnu packages python-xyz)

#:use-module ((guix licenses) #:prefix license:)

#:use-module (guix build-system python)

#:use-module (guix build-system pyproject)

#:use-module (guix gexp)

#:use-module (guix download)

#:use-module (guix git-download)

#:use-module (guix packages))

I receive the following error:

ice-9/eval.scm:293:34: error: python-setuptools: unbound variable

hint: Did you forget a `use-modules' form?

Does anyone have any insight on what is happening here and if I am even on the right track to begin with?

Best,

Spencer
