uv toolchain uninstall should either error or remove all Pythons

[charliermarsh]

Right now, it looks like it passes an empty request vector to the command.

Further down, there's a match against matches!(requests.as_slice(), [PythonRequest::Any]). Is that possible to trigger?

[zanieb]

I think we should probably not uninstall them all without some sort of explicit opt-in, although it would loosely match the semantics of install.

[zanieb]

That match statement is just copied from the install implementation but isn't easy to get right now, maybe we should make it easier to construct the Any case in PythonRequest::parse e.g. with "any"

[charliermarsh]

I think it should probably just error? Require at least one specifier.

[charliermarsh]

Right now, how does the ::Any request work, how does one "create" that?

[charliermarsh]

We could also accept all or have a --all flag that's mutually exclusive with targets.

Right now, how does the ::Any request work, how does one "create" that?

I think it's just the default request and you can't ask for it explicitly which seems weird. "all" makes sense in this context but not for requests in general. Lots of reasonable approaches here, I think.
