# Description Require that any value that looks like it might be a number (starts with a digit, or a '-' + digit, or a '+' + digits, or a special form float like `-inf`, `inf`, or `NaN`) must now be treated as a number-like value. Number-like syntax can only parse into number-like values. Number-like values include: durations, ints, floats, ranges, filesizes, binary data, etc. # User-Facing Changes BREAKING CHANGE BREAKING CHANGE BREAKING CHANGE BREAKING CHANGE BREAKING CHANGE BREAKING CHANGE BREAKING CHANGE BREAKING CHANGE Just making sure we see this for release notes 😅 This breaks any and all numberlike values that were treated as strings before. Example, we used to allow `3,` as a bare word. Anything like this would now require quotes or backticks to be treated as a string or bare word, respectively. # 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.
