simple one-liner utility to create "conda" packages?

[Rich Lysakowski]

I am looking for a simple one-liner utility script to create "conda" packages from my module?

 

Does such a thing exist?  If so, where?   I just visited the  conda-forge (github.com) repo and don't see a repo with instructions for creating or "building" conda packages.  

This should be (almost) as simple as creating a pip package, or conda will constantly lag python-only tools for creating virtual environments.

I found "grayskull" after digging into the conda-blog website, but this is not prominent on the conda-forge website or github.  I will evaluate that for usability and simplicity.

Thank you.

I think grayskull is your answer.

Yes, it should probably be better advertised.

The other helpful resource is the template in:

https://github.com/conda-forge/staged-recipes/tree/main/recipes/example

While I agree that better docs are in order, a couple points:

1) conda has an inherently higher (potential) level of complexity, as it supports various non-Python packages: C libs, compiled python extensions, etc. 

That being said: the easy stuff should be easy.

2) creating “pip packages” ( I put that in quotes, because in a sense there is no such thing — I guess wheels are the closest)  is actually not that easy — the tools have been changing, there are multiple options, there are a lot of out-of-date docs and examples, and building C extensions is a real challenge. 

Other than better advertising of grayskull, the other thing I’d like to see are a few different example templates for conda-forge packages: one for pure Python, one for a simple C extension, etc….

But you can go find a recipe for an existing package if you know where to look.

Final note: making a conda-forge compatible package is a bit more complicated than a build it-yourself package. That’s because it needs to work with the CI infrastructure, and it’s a “curated“ system. But the extra up front costs are well worth it if you want to make your package available to the community.
