While working on #11288 I was having some trouble tracking the main REPL loop, so I've sent in a bunch of tiny refactorings on this branch. These are almost all of the "move code from one place to another" variety, and each commit is meant to be independent, _except for the last one_, which is trying to be a bit more clever to handle the decision of autocd'ing vs running a command. Feel free to just go through each commit and cherry pick the ones that look good. This leads to `evaluate_repl` going from ending on line 715 to ending on line 395. Again, this is mostly just moving code around, but I think this set of changes will make other changes around juggling the stack to avoid cloning easier to review.
Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
