Add rest and glob support to 'open' (#8506)
# Description This adds two different features to `open`: * The ability to pass more than one file to `open`. * Support for using globs in the filenames `open` will create a list stream and stream the output if there is more than one file opened Examples: ``` open file1.csv file2.csv file3.csv ``` ``` open *.nu | where $it =~ "echo" ``` # User-Facing Changes Multi-file and glob support in `open`. Original `open` functionality should continue as before. # 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.
