# Description This PR makes `append`/`prepend` more consistent, in particular, it allows you to work with ranges. Previously, you couldn't append a list by range: ```nu > 0..1 | append 2..4 ╭──────╮ │ 0 │ │ 1 │ │ 2..4 │ ╰──────╯ ``` Now it works: ```nu > 0..1 | append 2..4 ╭───╮ │ 0 │ │ 1 │ │ 2 │ │ 3 │ │ 4 │ ╰───╯ ``` # User-Facing Changes If someone needs the old behavior, then it can be obtained like this: ```nu > 0..1 | append [2..4] ╭──────╮ │ 0 │ │ 1 │ │ 2..4 │ ╰──────╯ ```
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.
