List available upgrades for tools with uv tool list --outdated

[traynier]

Is there no way of seeing updates for tools?

I currently have ruff 0.7.3 installed. I can successfully upgrade the tool using uv tool upgrade ruff, which updates it to 0.7.4, but would like to see what is available to upgrade first so that I can go and read the release notes (and put it in a script to show me when new versions are available). I used uv tool install ruff rather than just running via uvx so that I can use generate-shell-completion for it (that does not work when running under uvx as starting a command with uvx ruff ... does not show shell completion for ruff ...)

I am using uv 0.5.3 on Windows, with Powershell 7.4.6

> uv tool list
ruff v0.7.3
- ruff.exe

My uv installed version of ruff is old, but I would have expected to be able to use --outdated like on uv pip list / uv tree

> uv tool list --outdated
error: unexpected argument '--outdated' found

Usage: uv.exe tool list [OPTIONS]

I was looking at if there was other ways of doing this, but it appears not. Oddly, the shell completion for powershell gives --no-upgrade as an option on uv tool upgrade :

> uv tool upgrade --no-upgrade--allow-insecure-host
--all                         --index-strategy              --no-offline                  --resolution

--help                        --no-index                    --reinstall                   -V
--index                       --no-native-tls               --reinstall-package

no-upgrade

But running it just gives an error:

> uv tool upgrade --no-upgrade ruff
thread 'main' panicked at crates\uv-cli\src\options.rs:18:17:
internal error: entered unreachable code: Clap should make this impossible
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

But that appears to be more an issue with the uv generate-shell-completion powershell as that option is not listed in the help/documentation?

I think --outdated makes sense to add here.

I need to look at why we're panicking there -- that's strange.

@charliermarsh
In uv tool upgrade, --upgrade is enabled by default. However, why not remove both --upgrade and --no-upgrade from uv tool upgrade?
After all, it seems odd for an upgrade tool to have a flag that doesn't upgrade or to explicitly mention upgrading.

[charliermarsh]

It's a little bit of a pain. We have a common ResolverInstallerArgs struct for arguments that are shared across commands, and --upgrade is inherited from that.

[charliermarsh]

I'll fix it, it just requires some unfortunate duplication.

Cleaned up in #9318, but leaving this issue open since it's about --outdated.
