Replace row conditions with closures in commands (#7428) # Description This PR changes some commands that previously accepted row conditions (like `$it > 5`) as parameter to accept closures instead. The reasons are: a) The commands would need to move into parser keywords in the future while they feel more like commands to be implemented in Nushell code as a part of standard library. b) In scripts, it is useful to store the predicate condition in a variable which you can't do with row conditions. c) These commands are not used that often to benefit enough from the shorter row condition syntax # User-Facing Changes The following commands now accept **closure** instead of a **row condition**: - `take until` - `take while` - `skip until` - `skip while` - `any` - `all` This is a part of an effort to move away from shape-directed parsing. Related PR: https://github.com/nushell/nushell/pull/7365 # 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.
