# Description #7777 removed the `--numbered` flag from `each`, `par-each`, `reduce`, and `each while`. It was suggested at the time that it should be removed from `for` as well, but for several reasons it wasn't. This PR deprecates `--numbered` in anticipation of removing it in 0.96. Note: Please review carefully, as this is my first "real" Rust/Nushell code. I was hoping that some prior commit would be useful as a template, but since this was an argument on a parser keyword, I didn't find too much useful. So I had to actually find the relevant helpers in the code and `nu_protocol` doc and learn how to use them - oh darn ;-) But please make sure I did it correctly. # User-Facing Changes * Use of `--numbered` will result in a deprecation warning. * Changed help example to demonstrate the new syntax. * Help shows deprecation notice on the flag
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.
