Hi Guixers,
I'd like to update our abjad package to the later version of 3.6 but it
only supports python 3.10.
https://github.com/Abjad/abjad/releases/tag/v3.6
When will guix master branch see python 3.10 more or less?
all best,
jgart

Who knows? ;-)
Well, if you have python@3.10 packaged then you could use a
package transformation.
In ’(guix build-system python)’, you have ’package-with-explicit-python’
where you can replace the Python VM. Somehow, you could write something
along these lines,
--8<---------------cut here---------------start------------->8---
(define-public python-3.10
(package
(inherit python-3.9)
...
))
(define package-with-python-3.10
(package-with-explicit-python python-3.10
"python-" "python3.10-"
#:variant-property 'python-variant))
(define-public python-abjad
(package-with-python-3.10
(package
(name "python-adjad")
...
)))
--8<---------------cut here---------------end--------------->8---
*Warning*: it will “recompile” all the Python dependents using the
Python VM v3.10 so it could be some CPU.
BTW, maybe we could provide ’python-next’ pointing to whatever new
Python release. It would ease the upgrade, IMHO.
Cheers,
simon
