in repository guix.
commit 6bb6bab7c464bf99ef8da5d2a375fe8a42be78f3
Author: Sharlatan Hellseher <[email protected]>
AuthorDate: Tue Jul 15 22:12:53 2025 +0100
gnu: python-flit-scm: Improve package.
Reduce closure size by removing redundant python-setuptools and
python-wheel as it was a workaround import issue which was resolved by
using flit_core.buildapi directly.
* gnu/packages/python-build.scm (python-flit-scm): Fix indentation.
[arguments] <build-backend>: Let it auto detect.
<phases>: Add 'fix-backend.
[native-inputs]: Remove python-setuptools and python-wheel.
