# Description Prototype replacement for `enter`, `n`, `p`, `exit` built-ins implemented as scripts in standard library. MVP-level capabilities (rough hack), for feedback please. Not intended to merge and ship as is. _(Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience.)_ # User-Facing Changes New command in standard library ```nushell 〉use ~/src/rust/nushell/crates/nu-utils/standard_library/dirs.nu ---------------------------------------------- /home/bobhy ---------------------------------------------- 〉help dirs module dirs.nu -- maintain list of remembered directories + navigate them todo: * expand relative to absolute paths (or relative to some prefix?) * what if user does `cd` by hand? Module: dirs Exported commands: add (dirs add), drop, next (dirs next), prev (dirs prev), show (dirs show) This module exports environment. ---------------------------------------------- /home/bobhy ---------------------------------------------- 〉dirs add ~/src/rust/nushell /etc ~/.cargo -------------------------------------- /home/bobhy/src/rust/nushell -------------------------------------- 〉dirs next 2 ------------------------------------------- /home/bobhy/.cargo ------------------------------------------- 〉dirs show ╭───┬─────────┬────────────────────╮ │ # │ current │ path │ ├───┼─────────┼────────────────────┤ │ 0 │ │ /home/bobhy │ │ 1 │ │ ~/src/rust/nushell │ │ 2 │ │ /etc │ │ 3 │ ==> │ ~/.cargo │ ╰───┴─────────┴────────────────────╯ ------------------------------------------- /home/bobhy/.cargo ------------------------------------------- 〉dirs drop ---------------------------------------------- /home/bobhy ---------------------------------------------- 〉dirs show ╭───┬─────────┬────────────────────╮ │ # │ current │ path │ ├───┼─────────┼────────────────────┤ │ 0 │ ==> │ /home/bobhy │ │ 1 │ │ ~/src/rust/nushell │ │ 2 │ │ /etc │ ╰───┴─────────┴────────────────────╯ ---------------------------------------------- /home/bobhy ---------------------------------------------- 〉 ``` # Tests + Formatting Haven't even looked at stdlib `tests.nu` yet. Other todos: * address module todos. * integrate into std lib, rather than as standalone module. Somehow arrange for `use .../standard_library/std.nu` to load this module without having to put all the source in `std.nu`? * Maybe command should be `std dirs ...`? * what else do `enter` and `exit` do that this should do? Then deprecate those commands. 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. |
