# Description Adds improved errors for when a user uses a bashism that nu doesn't support. fixes #7237 Examples: ``` Error: nu::parser::shell_andand (link) × The '&&' operator is not supported in Nushell ╭─[entry #1:1:1] 1 │ ls && ls · ─┬ · ╰── instead of '&&', use ';' or 'and' ╰──── help: use ';' instead of the shell '&&', or 'and' instead of the boolean '&&' ``` ``` Error: nu::parser::shell_oror (link) × The '||' operator is not supported in Nushell ╭─[entry #8:1:1] 1 │ ls || ls · ─┬ · ╰── instead of '||', use 'try' or 'or' ╰──── help: use 'try' instead of the shell '||', or 'or' instead of the boolean '||' ``` ``` Error: nu::parser::shell_err (link) × The '2>' shell operation is 'err>' in Nushell. ╭─[entry #9:1:1] 1 │ foo 2> bar.txt · ─┬ · ╰── use 'err>' instead of '2>' in Nushell ╰──── ``` ``` Error: nu::parser::shell_outerr (link) × The '2>&1' shell operation is 'out+err>' in Nushell. ╭─[entry #10:1:1] 1 │ foo 2>&1 bar.txt · ──┬─ · ╰── use 'out+err>' instead of '2>&1' in Nushell ╰──── help: Nushell redirection will write all of stdout before stderr. ``` # User-Facing Changes **BREAKING CHANGES** This removes the `&&` and `||` operators. We previously supported by `&&`/`and` and `||`/`or`. With this change, only `and` and `or` are valid boolean operators. # 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.
