# Description While debugging #8139 I noticed that there was some error information coming from the toml crate that we were not displaying. This would've helped me to understand what was going on. So, this PR shows more verbose errors when toml fails to parse. ### Before ``` cargo llvm-cov show-env | from toml Error: nu:🐚:cant_convert (link) × Can't convert to structured toml data. ╭─[entry #1:1:1] 1 │ cargo llvm-cov show-env | from toml · ──┬── · ╰── can't convert string to structured toml data ╰──── ``` ### After ``` cargo llvm-cov show-env | from toml Error: nu:🐚:cant_convert (link) × Can't convert to structured toml data. ╭─[entry #1:1:1] 1 │ cargo llvm-cov show-env | from toml · ──┬── · ╰── can't convert string to structured toml data ╰──── help: TOML parse error at line 2, column 24 | 2 | LLVM_PROFILE_FILE="C:\CarTar\nushell-%p-%m.profraw" | ^ invalid escape sequence expected `b`, `f`, `n`, `r`, `t`, `u`, `U`, `\`, `"` ``` # User-Facing Changes _(List of all changes that impact the user experience here. This helps us keep track of breaking changes.)_ # 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 # 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.

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.
