Remove autoprinting of loop block values (#8618) # Description This removes autoprinting the final value of a loop, much in the same spirit as not autoprinting values at the end of statements. As we fix these corner cases, it becomes more consistent that to print to the screen in a script, you use the `print` command. This gives a noticeable performance improvement as a bonus. Before: ``` C:\Source\nushell〉 for x in 1..10 { $x } 1 2 3 4 5 6 7 8 9 10 ``` Now: ``` C:\Source\nushell〉 for x in 1..10 { $x } C:\Source\nushell〉 ``` # User-Facing Changes **BREAKING CHANGE** Loops like `for`, `loop`, and `while` will no longer automatically print loop values to the screen. # 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 -A clippy::needless_collect` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass > **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.
