01. Add Text Selection Event Handling

meta: id: text-selection-copy-01 feature: text-selection-copy priority: P2 depends_on: [] tags: [ui, events, clipboard]

objective:

• Add event listeners for text selection events in the TUI components
• Detect when text is selected by the user
• Prepare infrastructure for clipboard copy on selection release

deliverables:

• New event bus events for text selection
• Selection state tracking in app store
• Event listener setup in main components

steps:

1. Create new event bus events for text selection (selection.start, selection.end)
2. Add selection state to app store (selectedText, selectionStart, selectionEnd)
3. Add event listeners to key components that display text
4. Track selection state changes in real-time
5. Add cleanup handlers for event listeners

tests:

• Unit: Test event bus event emission for selection events
• Integration: Verify selection state updates when text is selected
• Manual: Select text in different components and verify state tracking

acceptance_criteria:

• Selection events are emitted when text is selected
• Selection state is properly tracked in app store
• Event listeners are correctly registered and cleaned up

validation:

• Run the app and select text in Player component
• Check app store selection state is updated
• Verify event bus receives selection events

notes:

• Need to handle terminal-specific selection behavior
• Selection might not work in all terminal emulators
• Consider using OSC 52 for clipboard operations
