# Description This PR updates `group-by` and `split-by` to allow other nushell Values to be used, namely bools. ### Before ```nushell ❯ [false, false, true, false, true, false] | group-by | table -e Error: nu:🐚:cant_convert × Can't convert to string. ╭─[entry #1:1:2] 1 │ [false, false, true, false, true, false] | group-by | table -e · ──┬── · ╰── can't convert bool to string ╰──── ``` ### After ```nushell ❯ [false, false, true, false, true, false] | group-by | table -e ╭───────┬───────────────╮ │ │ ╭───┬───────╮ │ │ false │ │ 0 │ false │ │ │ │ │ 1 │ false │ │ │ │ │ 2 │ false │ │ │ │ │ 3 │ false │ │ │ │ ╰───┴───────╯ │ │ │ ╭───┬──────╮ │ │ true │ │ 0 │ true │ │ │ │ │ 1 │ true │ │ │ │ ╰───┴──────╯ │ ╰───────┴───────────────╯ ``` # User-Facing Changes <!-- List of all changes that impact the user experience here. This helps us keep track of breaking changes. --> # 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 toolkit.nu; toolkit test stdlib"` 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 > ``` --> # 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. -->
