editor: Improve code completion filtering to provide fewer and more accurate suggestions ( #32928 )
...
Closes #32756
- Uses `filter_text` from LSP source to filter items in completion list.
This fixes noisy lists like on typing `await` in Rust, it would suggest
`await.or`, `await.and`, etc., which are bad suggestions. Fallbacks to
label.
- Add `penalize_length` flag to fuzzy matcher, which was the default
behavior across. Now, this flag is set to `false` just for code
completion fuzzy matching. This fixes the case where if the query is
`unreac` and the completion items are `unreachable` and
`unreachable!()`, the item with a shorter length would have a larger
score than the other one, which is not right in the case of
auto-complete context. Now these two items will have the same fuzzy
score, and LSP `sort_text` will take over in finalizing its ranking.
- Updated test to be more utility based rather than example based. This
will help to iterate/verify logic faster on what's going on.
