New commands: break
, continue
, return
, and loop
(#7230)
# Description This adds `break`, `continue`, `return`, and `loop`. * `break` - breaks out a loop * `continue` - continues a loop at the next iteration * `return` - early return from a function call * `loop` - loop forever (until the loop hits a break) Examples: ``` for i in 1..10 { if $i == 5 { continue } print $i } ``` ``` for i in 1..10 { if $i == 5 { break } print $i } ``` ``` def foo [x] { if true { return 2 } $x } foo 100 ``` ``` loop { print "hello, forever" } ``` ``` [1, 2, 3, 4, 5] | each {|x| if $x > 3 { break } $x } ``` # User-Facing Changes Adds the above commands. # 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 # 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.
