Fix #9992 I mistakenly messed up https://github.com/nushell/nushell/pull/10118 and this is a cleaned version. # Description * This pr changes the panic to errors while parsing `let`, now user will get the following errors: <img width="395" alt="scr" src="https://github.com/nushell/nushell/assets/1991933/4b39ac14-cd1f-47b3-9490-81009ca42717"> <img width="394" alt="scr" src="https://github.com/nushell/nushell/assets/1991933/71ce33ad-f4d0-4132-828f-9674b9603556"> <img width="440" alt="scr" src="https://github.com/nushell/nushell/assets/1991933/257eab4d-1a72-42db-b09e-f42bef33d2ec"> * `out+err>` is cached by `parse_expression` but not this, which may be a potential problem. * `Commond(None, ..)` remains panic for future bug report because I don't actually know when/how does it happen # User-Facing Changes Nushell won't crash when user typing `let a = 1 err> ...` # Tests + Formatting - `cargo fmt --all -- --check` : OK - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` : OK - `cargo test --workspace` : OK - `cargo run -- -c "use std testing; testing run-tests --path crates/nu-std"` : OK # After Submitting None Co-authored-by: Horasal <horsal@horsal.dev>
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.
