Third party dependencies? about buck2 HOT 5 CLOSED

How does this currently work inside facebook?
Is everything except for rust vendored with build files written by hand?

Looking at nixpkgs and bazel-central-registry for inspiration, I think that in an ideal world maybe we could get to a starlark-central-registry (ie. something sharable with Bazel et al). Looking at the bazel-central-registry package coverage it doesn't seem like that idea has progressed too far. Maybe this is unnecessary, if it's easy enough to write the Reindeer-esque shim for other languages?

You can do the import and vendor approach like we do for Reindeer and bootstrapping Buck2. But we do want to do something better - we're just not sure what quite yet. We'll be having discussions internally, but if you have good ideas, please do share!

Not necessarily by hand, there are tools for this, but yes third-party packages get BUCK files (and those are often written by hand).

The buckaroo macros for Buck1 are pretty good, and predated bzlmod by some time. It's not perfect by any means, but since it was meant to interop with buck that might be a good place to start: https://github.com/LoopPerfect/buckaroo

I'll close this assuming the answers above did address your question but feel free to follow up if not.
