# Description This PR moves the `where` command to a parser keyword. While it still uses the shape-directed parsing dictated by the signature, we're free to change the parsing code now to a custom one once we remove the syntax shapes. As a side effect, the `where -b` flag was removed and its functionality has moved to the new `filter` command. Just FYI, other commands that take row conditions: - `take until` - `take while` - `skip until` - `skip while` - `any` - `all` We can either move these to the parser as well or make them accept a closure instead of row condition. # User-Facing Changes New `filter` command which replaces `where -b` functionality. # 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.
