# Description For years, Nushell has used `let-env` to set a single environment variable. As our work on scoping continued, we refined what it meant for a variable to be in scope using `let` but never updated how `let-env` would work. Instead, `let-env` confusingly created mutations to the command's copy of `$env`. So, to help fix the mental model and point people to the right way of thinking about what changing the environment means, this PR removes `let-env` to encourage people to think of it as updating the command's environment variable via mutation. Before: ``` let-env FOO = "BAR" ``` Now: ``` $env.FOO = "BAR" ``` It's also a good reminder that the environment owned by the command is in the `$env` variable rather than global like it is in other shells. # User-Facing Changes BREAKING CHANGE BREAKING CHANGE This completely removes `let-env FOO = "BAR"` so that we can focus on `$env.FOO = "BAR"`. # 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 / Before Submitting integration scripts to update: - ✔️ [starship](https://github.com/starship/starship/blob/master/src/init/starship.nu) - ✔️ [virtualenv](https://github.com/pypa/virtualenv/blob/main/src/virtualenv/activation/nushell/activate.nu) - ✔️ [atuin](https://github.com/ellie/atuin/blob/main/atuin/src/shell/atuin.nu) (PR: https://github.com/ellie/atuin/pull/1080) - ❌ [zoxide](https://github.com/ajeetdsouza/zoxide/blob/main/templates/nushell.txt) (PR: https://github.com/ajeetdsouza/zoxide/pull/587) - ✔️ [oh-my-posh](https://github.com/JanDeDobbeleer/oh-my-posh/blob/main/src/shell/scripts/omp.nu) (pr: https://github.com/JanDeDobbeleer/oh-my-posh/pull/4011)
