This is the first PR towards migrating to a new `$env.PWD` API that returns potentially un-canonicalized paths. Refer to PR #12515 for motivations. ## New API: `EngineState::cwd()` The goal of the new API is to cover both parse-time and runtime use case, and avoid unintentional misuse. It takes an `Option<Stack>` as argument, which if supplied, will search for `$env.PWD` on the stack in additional to the engine state. I think with this design, there's less confusion over parse-time and runtime environments. If you have access to a stack, just supply it; otherwise supply `None`. ## Deprecation of other PWD-related APIs Other APIs are re-implemented using `EngineState::cwd()` and properly documented. They're marked deprecated, but their behavior is unchanged. Unused APIs are deleted, and code that accesses `$env.PWD` directly without using an API is rewritten. Deprecated APIs: * `EngineState::current_work_dir()` * `StateWorkingSet::get_cwd()` * `env::current_dir()` * `env::current_dir_str()` * `env::current_dir_const()` * `env::current_dir_str_const()` Other changes: * `EngineState::get_cwd()` (deleted) * `StateWorkingSet::list_env()` (deleted) * `repl::do_run_cmd()` (rewritten with `env::current_dir_str()`) ## `cd` and `pwd` now use logical paths by default This pulls the changes from PR #12515. It's currently somewhat broken because using non-canonicalized paths exposed a bug in our path normalization logic (Issue #12602). Once that is fixed, this should work. ## Future plans This PR needs some tests. Which test helpers should I use, and where should I put those tests? I noticed that unquoted paths are expanded within `eval_filepath()` and `eval_directory()` before they even reach the `cd` command. This means every paths is expanded twice. Is this intended? Once this PR lands, the plan is to review all usages of the deprecated APIs and migrate them to `EngineState::cwd()`. In the meantime, these usages are annotated with `#[allow(deprecated)]` to avoid breaking CI. --------- Co-authored-by: Jakub Žádník <kubouch@gmail.com> |

nu-protocol
The nu-protocol crate holds the definitions of structs/traits that are used throughout Nushell. This gives us one way to expose them to many other crates, as well as make these definitions available to each other, without causing mutually recursive dependencies.
