Summary
In the TUI TextInput, pressing moves cursor to position 0 (start of the entire input) and to v.length (end of the entire input). For a single long prompt that wraps across multiple terminal lines, this ignores the visual line the cursor is on.
Expected Behavior
- First <Home>: snap cursor to start of the current visual line (the line as it appears on screen)
- Second <Home> (press again): snap to logical start (
position 0)
- First <End>: snap cursor to end of the current visual line
- Second <End> (press again): snap to logical end (
v.length)
- Ctrl+Home: always go to logical start (absolute position 0)
- Ctrl+End: always go to logical end (absolute
v.length)
Technical Notes
The infrastructure already exists:
cursorLayout() in ui-tui/src/lib/inputMetrics.ts computes the current visual line given terminal widthvisualLines() returns start/end boundaries of each visual line- The fix lives in
ui-tui/src/components/textInput.tsx (~lines 796-808 currently)
A similar approach is used by GNU Readline and most modern TUIs (e.g., Textual, Bubble Tea).
