Closes #15160 # User-Facing Changes Certain "variable not found" errors no longer highlight the surrounding block. Before: ```nushell do { match foo { _ => $in } } Error: nu:🐚:variable_not_found × Variable not found ╭─[entry #1:1:1] 1 │ ╭─▶ do { 2 │ │ match foo { 3 │ │ _ => $in 4 │ │ } 5 │ ├─▶ } · ╰──── variable not found ``` After: ```nushell Error: nu:🐚:variable_not_found × Variable not found ╭─[entry #1:3:10] 2 │ match foo { 3 │ _ => $in · ─┬─ · ╰── variable not found ```
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.
