cargo-add's PR was minimal to ensure we had settled on the CLI before adding references to the CLI and have cascading churn. This the command documentation and adds references to that command.

Import `cargo remove` into cargo ## What does this PR try to resolve? This PR merges `cargo remove` from [cargo-edit](https://github.com/killercup/cargo-edit) into cargo. ### Motivation - General approval from community, see #5586 and #10520. - Satisfying symmetry between add and remove. - Help users clean up their manifests (for example, when users forget to remove optional dependencies from feature lists). With #10472, cargo-add was added to cargo. As part of that discussion, it was also proposed that `cargo rm` (now `cargo remove`) eventually be added as well. ### Drawbacks - Additional code always opens the door for more bugs and features - The scope of this command is fairly small though - Known bugs and most known features were resolved before this merge proposal ### Behavior `cargo remove` operates on one or more dependencies from a manifest, removing them from a specified dependencies section (using the same flags as `cargo-add`) and from `[features]` activations if the dependency is optional. Feature lists themselves are not automatically removed when made empty. Like with cargo-add, the lock file is automatically updated. Note: like `cargo add`, `cargo remove` refers to dependency names, rather than crate names, which can be different with the presence of the `name` field. Note: `cargo rm` has been renamed to `cargo remove`, based on prior art and user feedback (see [discussion](#10520)). Although this renaming is arguably an improvement, adding an `rm` alias could make the switch easier for existing users of cargo-edit (at the cost of a naming conflict which would merit insta-stabilization). #### Help output <details> ```shell $ cargo run -- remove --help cargo-remove Remove dependencies from a Cargo.toml manifest file USAGE: cargo remove [OPTIONS] <DEP_ID>... ARGS: <DEP_ID>... Dependencies to be removed OPTIONS: -p, --package [<SPEC>...] Package to remove from -v, --verbose Use verbose output (-vv very verbose/build.rs output) --manifest-path <PATH> Path to Cargo.toml --offline Run without accessing the network -q, --quiet Do not print cargo log messages --dry-run Don't actually write the manifest -Z <FLAG> Unstable (nightly-only) flags to Cargo, see 'cargo -Z help' for details -h, --help Print help information SECTION: --dev Remove as development dependency --build Remove as build dependency --target <TARGET> Remove as dependency from the given target platform ``` </details> #### Example usage ``` cargo remove serde cargo remove criterion httpmock --dev cargo remove winhttp --target x86_64-pc-windows-gnu cargo remove --package core toml ``` ## How should we test and review this PR? This is following the pattern from cargo-add which was implemented in three different PRs (implementation, documentation, and completions), in the interest of reducing the focusing discussions in each PR and allowing cargo-add's behavior to settle to avoid documentation churn. 1. #10472 2. #10578 3. #10577 The remaining changes (documentation and shell completions) will follow shortly after. Some work has already begun on this feature in #11059. Work on this feature was carried out on the [`merge-rm`](killercup/cargo-edit@master...merge-rm) branch of cargo-edit with PRs reviewed by `@epage.` If you are interested in seeing how this feature evolved to better match cargo's internals, you might find the commit history there to be helpful. As this PR is reviewed, changes will be made both here and on that branch, with the commit history being fully maintained on the latter. `cargo remove` is structured like most other subcommands: - `src/bin/cargo/commands/remove.rs` contains the cli handling and top-level execution. - `src/cargo/ops/cargo_remove.rs` contains the implementation of the feature itself. In order to support this feature, the `remove_from_table` util was added to `util::toml_mut::manifest::LocalManifest`. Tests are split out into a separate commit to make it easier to review the production code and tests. Tests have been implemented with `snapbox`, structured similarly to the tests of `cargo add`. ### Prior art - Python: [`poetry remove`](https://python-poetry.org/docs/cli/#remove) - Supports dry run - JavaScript: [`yarn remove`](https://yarnpkg.com/cli/remove) - Supports wildcards - JavaScript: [`pnpm remove`](https://pnpm.io/cli/remove) - Go: [`go get`](https://go.dev/ref/mod#go-get) - `go get foo@none` to remove - Julia: [`pkg rm`](https://docs.julialang.org/en/v1/stdlib/Pkg/) - Supports `--all` to remove all dependencies - Ruby: [`bundle remove`](https://bundler.io/v2.2/man/bundle-remove.1.html) - Dart: [`dart pub remove`](https://dart.dev/tools/pub/cmd/pub-remove) - Supports dry run - Lua: [`luarocks remove`](https://github.com/luarocks/luarocks/wiki/remove) - Supports force remove - .NET: [`Uninstall-Package`](https://docs.microsoft.com/en-us/nuget/reference/ps-reference/ps-ref-uninstall-package) - Supports dry run - Supports removal of dependencies - Supports force remove (disregards dependencies) - Haxe: [`haxelib remove`](https://lib.haxe.org/documentation/using-haxelib/#remove) - Racket: [`raco pkg remove`](https://docs.racket-lang.org/pkg/cmdline.html#%28part._raco-pkg-remove%29) - Supports dry run - Supports force remove (disregards dependencies) - Supports demotion to weak dependency (sort of a corollary of force remove) ### Insta-stabilization In the discussion of `cargo add`'s stabilization story ([Zulip stream](https://rust-lang.zulipchat.com/#narrow/stream/246057-t-cargo/topic/Stablizing.20cargo-add)), it was brought up that the feature might benefit from being insta-stabilized to avoid making the cargo-edit version of the binary hard to access. Since `cargo rm` (from cargo-edit) was renamed to `cargo remove` here, [such a conflict no longer exists](https://crates.io/search?q=cargo%20remove), so this is less of a concern. Since this feature is already has a had a long run of user testing in cargo-edit and doesn't have unsettled UI questions like cargo-add did, it might still be a candidate for insta-stabilization. ### Deferred work Necessary future work: - Add documentation. - Add shell completions. - Perform GC on workspace dependencies when they are no longer used (see #8415). - This is inspired by a feature from the RFC that was dropped (unused dependencies triggering a warning) - This was deferred out to avoid challenges with testing nightly features It was found in the review of `cargo add` that it was best to defer these first two items to focus the discussion and as there was still behavior churn during the review of cargo-add. ### Future Possibilities The following are features which we might want to add to `cargo remove` in the future: - Add a `cargo rm` alias to ease transition for current cargo-edit users - Automatically convert between dash and underscores in deps: killercup/cargo-edit#690 - Remove unused dependencies: killercup/cargo-edit#415 - Clean up caches: killercup/cargo-edit#647 ### Additional information Fixes #10520.

What does this PR try to resolve?
cargo-add's PR was minimal to ensure we had settled on the CLI before
adding references to the CLI and have cascading churn. This the command
documentation and adds references to that command.
How should we test and review this PR?
I'm unsure what testing is not automated for the documentation (like link checking).
Additional information
To keep the PRs focused, I am submitting completions separate from documentation updates so one does not get blocked on the other and its easier to see all relevant parts and sign off on them.
