Pair plugin for reovim - bracket matching, highlighting, and auto-pair insertion
This plugin provides:
- Rainbow bracket coloring based on nesting depth (6-color cycle)
- Matched pair highlighting when cursor is inside brackets
- Bold + underline highlighting when cursor is directly ON a bracket
- Unmatched bracket warning (red underline)
- Auto-insertion of closing brackets with cursor positioning
Supported Brackets
- Round brackets:
() - Square brackets:
[] - Curly brackets:
{}
Note: Angle brackets <> are intentionally excluded as they conflict with
operators (->, =>, <=, >=, <<, >>) in most languages.
Highlighting Behavior

|---|---|
On bracket ( or ) |

State Management
The plugin stores PairState in PluginStateRegistry, tracking:
