# Description This PR improves the error message if an environment variable (that's visible before the parser begins) is used in the form of `$PATH` instead of `$env.PATH`. Before: ``` Error: nu::parser::variable_not_found × Variable not found. ╭─[entry #31:1:1] 1 │ echo $PATH · ──┬── · ╰── variable not found. ╰──── ``` After: ``` Error: nu::parser::env_var_not_var × Use $env.PATH instead of $PATH. ╭─[entry #1:1:1] 1 │ echo $PATH · ──┬── · ╰── use $env.PATH instead of $PATH ╰──── ``` # User-Facing Changes Just the improvement to the error message # 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 -A clippy::result_large_err` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass - `cargo run -- crates/nu-std/tests/run.nu` to run the tests for the standard library > **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. --> |
