Bazel BUILD rule / BUILD file about clif

[ChrisCummins]

FWIF, I have found that pybind11_bazel works flawlessly and is a pleasure to use. It took a bit of figuring out how to use it as (at the time) the repo {is,was} largely undocumented. You can my example here:

https://github.com/ChrisCummins/phd/tree/master/learn/python/pybind

Bad news: at the moment Bazel has no features to do so.
Good news: it's a work in progress (and we are participating).

Would it be possible to use a bazel genrule for the time being?

[mrovner]

I've heard people do it in ad-hoc fragile way only for their projects.

@mrovner Mike, would you mind sharing an ETA or something for this project? Thanks.

[mrovner]

My uninformative guess is around next year. I know people are actively working on this but it's hard.

[hlopko]

bazelbuild/bazel#4570 is the blocker.

[ChrisCummins]

Any update on this, or examples of ad-hoc workarounds with genrules?

[yegle]

The blocker was fixed recently. Any update on the bazel rules?

[hlopko]

Yup that is correct, AFAIK we can now implement clif rules in Starlark. We (the Bazel rules team) don't plan to proactively do that, but we will gladly help anybody who will.

[dmadisetti]

So there's a external project that implements clif for Bazel! See tink-crypto/tink@6c476e3

I'm not sure how stale this repository is, but this hopefully reduces the engineering effort if this ticket was to ever be addressed.

[gpshead]

A little ironic given that I believe @rwgk has re-implemented tink's CLIF use in pybind11 (is that released yet?).

[dmadisetti]

@ChrisCummins Cheers. The fact the project looks pretty alive is also reassuring. Pretty easy to set up and port

[rwgk]

Yes, the tink pybind11 code was released, although the tink team is still working on building outside the google environment.

I see the author of the tink clif build rules is Bartosz, the same person I was working with when converting the clif bindings to pybind11. I wasn't aware of the tink clif build rules, but I'm pretty sure there were blockers, like clif itself not building. Bartosz' code predates him contacting me to ask when OSS clif will be updated.

It was recently updated, see #36 (comment) for some background.
