# Description This makes `LabeledError` much more capable of representing close to everything a `miette::Diagnostic` can, including `ShellError`, and allows plugins to generate multiple error spans, codes, help, etc. `LabeledError` is now embeddable within `ShellError` as a transparent variant. This could also be used to improve `error make` and `try/catch` to reflect `LabeledError` exactly in the future. Also cleaned up some errors in existing plugins. # User-Facing Changes Breaking change for plugins. Nicer errors for users.
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.
