Refer to #12603 for part 1. We need to be careful when migrating to the new API, because the new API has slightly different semantics (PWD can contain symlinks). This PR handles the "obviously safe" part of the migrations. Namely, it handles two specific use cases: * Passing PWD into `canonicalize_with()` * Passing PWD into `EngineState::merge_env()` The first case is safe because symlinks are canonicalized away. The second case is safe because `EngineState::merge_env()` only uses PWD to call `std::env::set_current_dir()`, which shouldn't affact Nushell. The commit message contains detailed stats on the updated files. Because these migrations touch a lot of files, I want to keep these PRs small to avoid merge conflicts.
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.
