Add feature to generate recipe in this new format.

It would be nice to add more examples so it would be easier to add this. :)

Awesome! Would love to see this.
We don't have so many examples of the new format available yet. We have some examples of the previous variant in the emscripten-forge and boa-forge repositories:

• https://github.com/mamba-org/boa-forge
• https://github.com/emscripten-forge/recipes

Currently using grayskull + boa convert + some sed to feed the new recipe to rattler-build.
Would love to have support in grayskull directly :-)

If nobody started working on this yet, I could give it a try in the coming weeks (no promise).
Haven't looked yet, but should most work be in https://github.com/marcelotrevisani/souschef ?

[wolfv]

That would be amazing. No one is working on it afaik :)

Now that the conda-recipe-manager is up and running with conversion integration tests with rattler-build, should we consider having grayskull incorporate conda-recipe-manager as the translation layer? At least as a first-pass implementation?

[marcelotrevisani]

Yes, sure
I just don't have the capacity now for that, due to some personal and work obligations.
However, I can review the PR
If you would like to give a try please let me know :)

I might be able to start on this next week. I have some low-hanging fruit that'll improve compatibility with rattler-build I want to address and then I should be free to take a look.

[schuylermartin45]

Not to set myself up for failure, but this looks relatively straight-forward so far. This will be the first project that consumes conda-recipe-manager, so I'm sure there will be some unexpected hurdles.

My current plan is to add a new flag to grayskull. If it is set, perform the conversion in utils.generate_recipe() before we dump the recipe contents. I'll also automatically use recipe.yaml over meta.yaml where applicable.

I put up a draft PR until I can get unblocked on a few things. See my PR description for more details.
