I can do this with some scripting, but maybe there is already a way to list python files that are not used? I vendored in some old code that has a lot of things I don't need and that I don't want to update so that it lints and checks properly.

pants peek ::

includes dependency information, so one approach would be to do your own processing based on that, as it sounds like you're aware of. (I don't personally know of a built-in way to do it/prepackaged way to answer that)

Thanks, yes, that's what I can do, just hoping I might not need to 🙂

This is basically impossible to do in Pants since Pants supports target less goals. In other words answering the question means looking at all the roots of a dependency graph and deciding which ones you personally consider unused. With that human provided input, you can then automate the calculation.

yes, I meant unused from a target's point of view. I can list all dependencies and subtract that list from all the files.

So you mean files no target globs?
