Add --workspace to cargo add

[jmg-duarte]

Problem

I am working on a project where we're placing all dependencies in the workspace. Whenever I add a new dependency I want to be able to add it to the workspace rather than the local Cargo.toml file.

Proposed Solution

The command

cargo add tokio -F full --workspace

Should add tokio to the the current Cargo.toml like so:

[dependencies]
tokio = { workspace = true, features = ["full"] }

And to the workspace Cargo.toml:

[dependencies]
tokio = "1" # or whatever version it would add

To find the workspace file, the command would go up the directories looking for Cargo.toml where members contains the current package.

Additionally, the --workspace flag could take a parameter with the workspace Cargo.toml's path.

Notes

If the feature is to be implemented, I am available to do it!

Thanks for the proposal. This is probably a duplicate of #10608?

Yes and no 😅 the ideas are clearly siblings but the interface I was looking for is not the same as the one proposed on that issue.

I feel that my interface is much more clear cut than those discussed there. It's clear where you're adding by default (the current package) and the flag makes it explicit where it goes to.

But let me know if I should move this discussion there!

Thanks for the clarification! Yeah the design space is quite the same, so better discussing the needs and alternatives altogether :)

Closing this and feel free to drop ideas there.
