# Description Fixes: #8402 #8391 The cause of these issue if when we want to evaluate a expression with `Value::Error`, nushell show error immediately. To fix the issue, we can wrap the `Value::Error` into a `Value::Record`. So user can see the message he want. # User-Facing Changes Before ``` ❯ try { 1 / 0 } catch {|e| echo $"error is ($e)"} Error: nu:🐚:division_by_zero × Division by zero. ╭─[entry #2:1:1] 1 │ try { 1 / 0 } catch {|e| echo $"error is ($e)"} · ┬ · ╰── division by zero ╰──── ``` After ``` ❯ try { 1 / 0 } catch {|e| echo $"error is ($e)"} error is {msg: Division by zero., debug: DivisionByZero { span: Span { start: 43104, end: 43105 } }, raw: DivisionByZero { sp an: Span { start: 43104, end: 43105 } }} ``` As we can see, error becomes a record with `msg`, `debug`, `raw` columns. 1. msg column is a user friendly message. 2. debug column is more about `Value::Error` information as a string. 3. raw column is a `Value::Error` itself, if user want to re-raise the error, just use `$e | get raw` # Tests + Formatting Don't forget to add tests that cover your changes. Make sure you've run and fixed any issues with these commands: - `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass > **Note** > from `nushell` you can also use the `toolkit` as follows > ```bash > use toolkit.nu # or use an `env_change` hook to activate it automatically > toolkit check pr > ``` # After Submitting If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date. |

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.
