How to support poetry / pyproject.toml?

[dimaqq]

Hi, I'd love to be able to write ros2/catkin-able components that use modern dependency management tools.

Specifically, I'd love to specify dependencies in pyproject.toml and use poetry to maintain/build/test the package.
(that would be as an alternative to setup.py and `

I could totally contribute some code towards this.

It's not yet supported, is it?

How do I go about that?

Do you want to use pyproject.yaml to install dependencies? If so you should forward your request to https://github.com/ros-infrastructure/rosdep

Or to you want to replace setup.py? I don't think that will get implemented for ROS1 because it's end of line. You have a better chance to have https://github.com/colcon support it.

I was thinking about the latter.
Allowing modern 3p packages to be used in ros2 projects, for robotics devs.

The earlier is interesting too, and quite straightforward, may be a good first step 😉

I found a related issue in the colcon project: colcon/colcon-core#208

Allowing modern 3p packages to be used in ros2 projects, for robotics devs.

For ros2 see:

• Colcon fails to build valid PEP 517 projects colcon/colcon-core#208
• setup.py deprecation warning colcon/colcon-core#454

For ros1, I don't think this is going to be done, as noetic was the last release.
