How to propagate features from one project to another?

[julien-siguenza]

Hi there!

I'm a beginner with pixi, and I have a question that may sound basic.

I have a python project (python_project1), with a pixi.toml file containing a specific feature called "DEMO_APP".

I install some dependencies in this feature:

[feature.DEMO_APP.dependencies]
matplotlib = ">=3.9.4,<4"
pygame = ">=2.6.1,<3"
pymunk = ">=7.0.1,<8"
xlsxwriter = ">=3.2.3,<4"
openpyxl = ">=3.1.5,<4"

Then I have a second python project (python_project2) which is meant to use the first one (python_project1) as a dependency.

I would like to install the dependencies of the feature DEMO_APP in the pixi.toml file of this second project.

Is there a simple way to do that without having to duplicate all the dependencies in both files? (which I would really like to avoid).

One solution would be to define these dependencies in the section project.optional-dependencies of the pyproject.toml file of my first project (python_project1).

But the problem is that these optional dependencies can also be some conda dependencies, which cannot be managed with pip.

This is why I used the features of pixi to manage that.

But now I am struggling to spread these features in my second project (python_project2).

Thanks for helping! 🙏
