Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/recipe.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/recipe.yaml:

This is a rattler-build recipe and not yet lintable. We are working on it!

hum conda-smithy doesn't seem happy with the removal of recipe/meta.yaml. I might have missed something in the blog post

I got things a bit further along, but now am unsure what is needed to be done.

It sounds like we no longer need the redundant requirements at the top of the recipe.yaml. That's a nice change!

This seems like it's going to be a slog. There are a lot of changes required to get this to render. For example,

    build:
      ignore_run_exports_from:
        - expat

needs to become:

    requirements:
      ignore_run_exports:
        from_package:
          - expat

in a bunch of places. The tests: bit at outside of outputs: needs to go.

rattler-build is also pretty unhappy with:

{{ \".\".join(version | split(\".\")[:2]) }}"

but I couldn't figure out a way to move this to context: that made it happy.

[xylar]

It seems like we might want to hold off on this until some simpler recipes can point the way. This is an unusually complex feedstock and probably a really good test of the robustness of rattler-build but maybe not a good choice for early adoption.

Also, see: https://github.com/conda-forge/pyremap-feedstock/pull/25#issuecomment-2322848607 https://github.com/conda-forge/conda-smithy/issues/2047 https://github.com/conda-forge/conda-smithy/issues/2047#issuecomment-2322848344

Thanks both for working on this. Indeed, GDAL will be a good test case and we are more than happy to tackle it, but we should probably indeed follow @xylar's suggestion and tackle a few easier feedstocks first :)
