I was hoping we could add Sophus to conda-forge such that people can do conda install -c conda-forge sophus to install Sophus to a conda environment.

I can do a PR if the maintainers think this is a good thing to have.

[strasdat]

@versatran01 yes, I'd like to do that at some point. I'm potentially anticipating some breaking changes in Sophus in the near future, and possibly want to tackle conda-forge afterwards.

[versatran01]

Ok. If I understand correctly, I think adding a package to conda-forge simply requires one to add a install script to the conda forge repo.

Also what will be the breaking change if you don’t mind disclosing it?

[NikolausDemmel]

If we have a breaking change it might be useful to release a version before, and even have it on conda before, so people can keep using the previous API by fixing the version (for a while at least).

[NikolausDemmel]

(i know you don't wanna do real releases. I just mean a tag people can refer to before the change.)

[strasdat]

For sure. I'm planning to have a release 22.10 tag. And in case I will move forward with the breaking changes (too early to share more details), I will in parallel introduce a beta branch (e.g. 23.04-beta).

@versatran01 do you want to go ahead with a PR for conda forge?

[versatran01]

Here is my first try. The conda recipe goes directly into the conda staged-recipe repo so there won't be any PR to Sophus itself. https://github.com/versatran01/staged-recipes/tree/sophus/recipes/sophus

which is based on the ceres recipe https://github.com/conda-forge/staged-recipes/pull/8168/commits/864cbf56a878888cc3622ff031955b4f8e048d84

Some questions for you:

1. What is the license and license family for Sophus?
2. Ok if I turn off basic logging and don't depend on fmt?
3. Do you want windows support? I don't have a win machine at hand to test anything.

[strasdat]

1. MIT
2. turn on basic-logging/turn off fmt sounds fine, at least for to begin with
3. Let's leave windows out for now. Eventually I'd like to support windows / CI through github actions. But this is more of a wish list task.

[versatran01]

This is going slower than I expected. https://github.com/conda-forge/staged-recipes/pull/20264

[versatran01]

This recipe is merged into conda-forge and should be ready to install via conda install -c conda-forge sophus
