Override hardcode package-dependency?

[woutervh]

I'm trying to find a simple solution for this problem:

the package pyautogui is quite old and has this in setup.py:

 'python3-Xlib;platform_system=="Linux" and python_version>="3.0"',
 'python-xlib;platform_system=="Linux" and python_version<"3.0"',

see https://github.com/asweigart/pyautogui/blob/master/setup.py

Many years later the python3-fork is now unmaintained and the original library now has proper python3-support

see https://stackoverflow.com/questions/74716030/what-is-the-difference-between-python-xlib-python3-xlib-pyxlib-and-xlib-in-pyt

Problem:
we want to use python-Xlib,
but python3-Xlib gets installed as a dependency of pyautogui.

I agree this problem should be fixed at package-level, but releases are glacial.

Is there currently a workaround or quick fix available, idealy in pyproject.toml
that we don't loose whenever we do "uv sync"

Both packages install an Xlib -pythonmodule,
so we want to override the Xlib-module installed by python3-Xlib, with the one provided by python-Xlib,

Is this the same as #4422? (there's a solution there, I believe)

@zanieb Amazing. I never saw sys_platform == 'never' before

Nice elegant solution with:

[project]
name = "demo"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.12"
dependencies = [
    "pyautogui>=0.9.54",
    "python-xlib>=0.33",
]

[tool.uv]
override-dependencies = [
    "python3-xlib; sys_platform == 'never'",
]
