pixi-to-conda-lock program that convert quickly generated pixi.lock to conda-lock.yml

[basnijholt]

Hi all!

I have been experimenting with Pixi lately and have been amazed about its speed, especially how it is able to generate a lockfile in seconds–instead of minutes in the case of conda-lock.

As a proof of principle, I therefore created the pixi-to-conda-lock package.

It currently assumes the latest pixi.lock format (I just haven't tested with older versions).

Basically uvx pixi-to-conda-lock pixi.lock will generate a conda-lock.yml for you.

I have some other code in unidep here that can create a pixi.toml file from a environment.yaml file, however, it is still a PR.

I wonder what you folks think!

I have not tried it out yet (I don't have any particular use case) but I love the idea, and I love the modular nature.

I could see conda-lock depending on this in order to add support for pixi as a backend.

I think I've even done most of the complementary work with the conda-lock render-lock-spec --kind=pixi.toml feature on the main branch.

@maresb, cool, I will checkout the --kind=pixi.toml code!

BTW, I did a full rewrite of pixi-to-conda-lock using py-rattler, it is 30% of the previous code and muuuuuuuch faster and more reliable now.

Please keep me up-to-date with all your work around this subject, and let's also think about how we can integrate it directly here.

I've also been wanting to update the README here to mention pixi and related tools, so please feel free to propose a blurb.
