# Description In #16028 I also added a test to check that identifiers are valid to ensure that we have consistency there. But I only checked for alphanumeric strings as identifiers. It doesn't allow underscores or dashes. @Bahex used in his PR about #15682 a dash to separate words. So expanded the test to allow that. # User-Facing Changes None. # Tests + Formatting The `assert_identifiers_are_valid` now allows dashes. # After Submitting The tests in #15682 should work then.
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.
