pkg_ressources removed in py 3.12

[janesser]

https://docs.python.org/3/whatsnew/3.12.html

There is no more pkg_resources in python 3.12 (which is standard in e.g. ubuntu noble)

Longer situational description here: mu-editor/mu#2485

Let's see if we can fix it.

> pipx run  yglu
Traceback (most recent call last):

    import pkg_resources

EDIT: affected version is yglu@1.1.2 (which is actually latest on pypy)

[janesser]

in fact its yagl.

EDIT: quick & dirty workaround of yagl/init,py

You can also install setuptools with pip3 install setuptools

[greyfairer]

@lbovet for me, it works, but it recently started showing ugly warnings with the latest version of setuptools:

/root/.local/share/pipx/venvs/yglu/lib/python3.12/site-packages/yaql/init.py:16: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.
import pkg_resources

I see that YAQL itself has fixed it by switching to PBR in openstack/yaql@bacaa70, but it's released as 3.1.0, and yglu specifies yaql>=1.1.3,<3.0.

I think you can upgrade to yaql<4.0. They did remove the format function, but AFAICS, you only use YAQL to evaluate expressions, not for formatting.

My current workaround:

RUN pip install yglu
RUN pip install --upgrade --no-deps "yaql>=3.0,<4.0"

[mtnpke]

It is possible to use yglu==1.1.1 because it does not have the <3.0 constraint on yaql.
