# Description This PR improves the `metadata set` command by returning a clear error when both `--datasource-filepath` and `--datasource-ls` flags are used together. These flags are meant to be mutually exclusive, and previously this conflicting usage was silently ignored. # User-Facing Changes * Users will now see an error message if they use both `--datasource-filepath` and `--datasource-ls` together in `metadata set`. # Tests + Formatting * [x] Added test at `crates/nu-command/tests/commands/debug/metadata_set.rs` to verify the error behavior. * [x] Ran `cargo fmt --all -- --check` * [x] Ran `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` * [x] Ran `cargo test --workspace` # After Submitting N/A
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.
