Pipx: add search subcommand

[zachvalenta]

How would this feature be useful?

tldr it would be cool if users could search a subset of PyPI packages that were CLIs

$ pipx search lint

flake8
pylint

$ pipx search dependencies

poetry
pipenv

On one hand, pip already offers search functionality. But it could be improved in a couple ways that would help pipx as a project:

• surfacing CLIs
• smarter search e.g. when I pip search postgres, pgcli doesn't come up in the results despite being arguably the best Postgres CLI. I don't know if this is a problem with pip's search, how packages are tagged in PyPI, or lack of tagging from packages maintainers.

Describe the solution you'd like

high-level I imagine we could port pip's existing search and utilize PyPI tags to filter down to just CLI pkgs

This is the one feature I would love, to search. I hope this comment and support for the original comment is well received.

In my view being able to search the pypi index would be most welcome indeed.

Kind regards

I think this ultimately goes to pypa/warehouse#284. tl;dr: PyPI does not offer a way to do what you (and we!) want, and we will need to wait for them to have something before this can ever happen.

I would recommend closing this as a "won't fix" or "upstream" for now, since there is really nothing pipx can do here in the foreseeable future, and this ticket would likely be long forgotten by the time there is something actionable 😞
