# 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. |

Nushell REPL
This directory contains the main Nushell REPL (read eval print loop) as part of the CLI portion of Nushell, which creates the nu binary itself.
Current versions of the nu binary will use the Nu argument parsing logic to parse the commandline arguments passed to nu, leaving the logic here to be a thin layer around what the core libraries.
