Please, check our [contributing guide](../CONTRIBUTING.md) and talk to the core team before making major changes. Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience. --> Spreading lists automatically when calling externals was deprecated in 0.89 (#11289), and this PR is to remove it in 0.91. # User-Facing Changes <!-- List of all changes that impact the user experience here. This helps us keep track of breaking changes. --> The new error message looks like this: ``` > ^echo [1 2] Error: nu:🐚:cannot_pass_list_to_external × Lists are not automatically spread when calling external commands ╭─[entry #13:1:8] 1 │ ^echo [1 2] · ──┬── · ╰── Spread operator (...) is necessary to spread lists ╰──── help: Either convert the list to a string or use the spread operator, like so: ...[1 2] ``` The old error message didn't say exactly where to put the `...` and seemed to confuse a lot of people, so hopefully this helps. # Tests + Formatting <!-- Don't forget to add tests that cover your changes. Make sure you've run and fixed any issues with these commands: - `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass (on Windows make sure to [enable developer mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging)) - `cargo run -- -c "use std testing; testing run-tests --path crates/nu-std"` to run the tests for the standard library > **Note** > from `nushell` you can also use the `toolkit` as follows > ```bash > use toolkit.nu # or use an `env_change` hook to activate it automatically > toolkit check pr > ``` --> There was one test to check that implicit spread was deprecated before, updated that to check that it's disallowed now. # After Submitting <!-- If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date. --> |

nu-protocol
The nu-protocol crate holds the definitions of structs/traits that are used throughout Nushell. This gives us one way to expose them to many other crates, as well as make these definitions available to each other, without causing mutually recursive dependencies.
