Refactoring

  • Unified text input system — replaced three separate text input implementations (FormWizard text-step, InputPanel, command-bar) with a shared architecture inspired by Claude Code:
    • text-cursor.ts — immutable Cursor class with NFC normalization and Intl.Segmenter-based grapheme navigation (CJK, emoji, Cyrillic, combining marks)
    • hooks/useTextInput.ts — keyboard logic hook with undo stack (Ctrl+Z / Cmd+Z), kill ring (Ctrl+K/U/W/Y), word navigation (Option+Left/Right), and all terminal editing shortcuts
    • components/TextInput.tsx — display component with sliding viewport that keeps cursor visible on text overflow

Bug Fixes

  • Cursor jumping on keyboard language switch — NFC normalization in Cursor constructor prevents position drift when IME sends NFD-encoded characters during layout switching
  • Text overflow at screen edge — single-line text inputs now use a sliding viewport instead of truncating from the end, keeping the cursor always visible
  • Undo stack over-drain — debounced undo snapshots captured current state, causing Ctrl+Z to pop identical text with no visible effect; fixed by skipping one matching snapshot before applying undo
  • React anti-pattern in textarea — setTaCursorCol was called inside a setTaLines updater function; moved out to prevent potential double-fire in concurrent mode
  • Timer leak on unmount — undo debounce timer is now cleared via useEffect cleanup when the component unmounts mid-debounce

Performance

  • Zero-cost cursor navigation — arrow keys, Home/End, word navigation reuse existing grapheme segments via Cursor._withPos() factory instead of re-running Intl.Segmenter on unchanged text
  • Single-pass insert — Cursor.insert() uses graphemeSegments() once instead of graphemeLength() + constructor re-segmentation
  • Render-path optimization — TextInput reads cursor.beforeSegs / cursor.afterSegs directly, avoiding join + re-segmentation on every render

New Features

  • Editing shortcuts — Ctrl+A/E (start/end), Ctrl+K/U/W (kill operations), Ctrl+Y (yank), Ctrl+Z / Cmd+Z (undo), Cmd+Backspace (kill to start), Ctrl+B/F (left/right), Ctrl+D (delete forward), Ctrl+H (backspace), Home/End keys

Tests

  • 96 new tests (1829 → 1923):
    • text-cursor.test.ts (61 tests) — grapheme segmentation, NFC normalization, CJK/emoji/Cyrillic handling, cursor navigation, editing, kill operations, display width
    • text-input.test.tsx (33 tests) — E2E via ink-testing-library: FormWizard text-step input/submit, cursor navigation, backspace, all Ctrl shortcuts, Cyrillic/emoji/CJK input, undo, step transitions, validation
