# Description

Thank you for improving Nushell. Please, check our [contributing

This PR makes it so that when using fuzzy matching, the score isn't
recomputed when sorting. Instead, filtering and sorting suggestions is
handled by a new `NuMatcher` struct. This struct accepts suggestions
and, if they match the user's typed text, stores those suggestions
(along with their scores and values). At the end, it returns a sorted
list of suggestions.

This probably won't have a noticeable impact on performance, but it
might be helpful if we start using Nucleo in the future.

Minor change: Makes `find_commands_by_predicate` in `StateWorkingSet`
and `EngineState` take `FnMut` rather than `Fn` for the predicate.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

When using case-insensitive matching, if you have two matches `FOO` and
`abc`, `abc` will be shown before `FOO` rather than the other way
around. I think this way makes more sense than the current behavior.
When I brought this up on Discord, WindSoilder did say it would make
sense to show uppercase matches first if the user typed, say, `F`.
However, that would be a lot more complicated to implement.

# 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` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library

> **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
> ```
