Paul, Pradyun, TP

• State update

  • TP: Just clobbered up something to wire up the resolver into pip CLI. I’m doing this in RequirementCommand (which install, download, and wheel subclass). Sounds about right?

    • https://github.com/pypa/pip/compare/provider-integration…uranusjr:resolver-switch?expand=1

    • What’s the process to introduce a new vendored lib into pip?

      • Pradyun: I can write documentation for that! :P

      • Pradyun: Add it to pyproject.toml{.backtick} – ala vendoring{.backtick}

  • Paul: Working on tests for the new resolver objects, and linking the code in with them.

    • What to do about A->B,C; B->D==version, C->D@url{.backtick}?

    • If we have a named requirement, name @ url, then when we prepare the URL, we need to check the name matches and error if not.

    • https://github.com/pypa/pip/compare/master…pfmoore:resolvelib_requirement?expand=1

• Next steps

  • Paul: Work on requirement/candidate abstraction, assemble the provider, start proposing PRs to master

  • TP: Finish the resolver wrapper, wire up Paul’s work after PR proposal, and propose PR for the CLI

  • Pradyun: I need to actually write the docs. Not blocked on anything.
