Hi @robertu94! I noticed that the following package(s) don't yet have maintainers:

• py-langsmith

Are you interested in adopting any of these package(s)? If so, simply add the following to the package class:

    maintainers("robertu94")

If not, could you contact the developers of this package and see if they are interested? You can quickly see who has worked on a package with spack blame:

$ spack blame py-langsmith

Thank you for your help! Please don't add maintainers without their consent.

You don't have to be a Spack expert or package developer in order to be a "maintainer," it just gives us a list of users willing to review PRs or debug issues relating to this package. A package can have multiple maintainers; just add a list of GitHub handles of anyone who wants to volunteer.

Confirmed the new homepages, commits, and all but one sha256. I am also not able to stage the python package to check dependencies though.

I identified several packages with ordering "issues" (e.g., dependencies before variants). There's a FIXME comment that can be removed (poorjit). The rest are suggestions.

@tldahlgren this is ready for you again when you get time. I understand if you guys are busy with ICS.

@tldahlgren I didn't intend to include the py-langsmith change here. That package releases super often, and I just needed a working version for something. I wouldn't have added it to spack, but since it was there I updated it so that it worked for me.

[robertu94]

Is this ready to merge or do we still need more changes @tldahlgren ?

Re-confirmed commits and sha256s, rest LGTM.
