## Context Closes #46698 This PR fixes a bug where the `cs` (change surrounds) operator fails on symmetric delimiters like quotes. In a sequence like `c s ' "`, Zed previously performed two independent searches. For a line like `I'm 'goˇod'`, the first step (`cs'`) correctly moves the cursor to the second quote: `I'm ˇ'good'`. However, when the replacement character `"` is pressed, `change_surrounds` would perform another scan from the new cursor position. Because quotes are symmetric, this second search would incorrectly match `'m '` as the target pair, leading to a broken result like `I"m "good'`. I've refactored the workflow to ensure the search happens only once. `prepare_and_move_to_valid_bracket_pair` now computes and stores the `Anchor` positions of the detected pair directly into the operator state. `change_surrounds` then simply reuses these anchors instead of re-executing the search. This ensures correctness for quotes while remaining consistent with Vim/Neovim cursor behavior. While this slightly increases coupling between these two functions, it is an intentional trade-off since they exclusively serve the `cs` operation. ## How to Review The main changes are in `crates/vim/src/surrounds.rs`. I renamed `check_and_move_to_valid_bracket_pair` to `prepare_and_move_to_valid_bracket_pair` and updated it to return the detected bracket anchors. In `change_surrounds`, I removed the redundant search logic and updated it to perform the replacement using the provided anchors. You can also see the updated `Operator::ChangeSurrounds` enum variant in `crates/vim/src/state.rs` which now carries the anchor data. ## Self-Review Checklist <!-- Check before requesting review: --> - [x] I've reviewed my own diff for quality, security, and reliability - [x] Unsafe blocks (if any) have justifying comments - [x] The content is consistent with the [UI/UX checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) - [x] Tests cover the new/changed behavior - [x] Performance impact has been considered and is acceptable Release Notes: - Fixed an issue where the `cs` Vim operator incorrectly identified symmetric quotes in certain contexts. --------- Co-authored-by: Conrad Irwin <conrad.irwin@gmail.com> |
