cli suggestions for --package

[dev-ardi]

Problem

cargo build --package Tab doesn't complete anything. It would be very useful!

Proposed Solution

I'd expect packages from my workspace to be suggested and if there's no match, then the dependencies.

Huh, we don't have this in bash and in zsh, we have it stubbed out

cargo/src/etc/_cargo

Lines 421 to 425 in fbca21b

	#FIXME: Disabled until fixed
	#gets package names from the manifest file
	_cargo_package_names() {
	_message -e packages package
	}

We are working on replacing those completions with native completions, see https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#native-completions

It appears the PR for cargo build --package has stalled out, see #14553.

bash and in zsh

I'm using fish, will it work for it?

[epage]

Fish provides their own completions for Cargo
https://github.com/fish-shell/fish-shell/blob/master/share/completions/cargo.fish

You might want to open an issue in their repo.

atm our native completions also provide fish completions. Unsure how well they play with fish's own completions. As we stabilize the feature, we'll need to decide what shells we officially support. If we consider supporting fish, we'll then need to work with fish regarding our two different set of completions. Fish does complete things that Cargo likely won't, like cargo add [TAB].

I think it's good to survey the community and ask what shell they use
