Description

Create HERO (Hyper-Efficient Read/Optimize) text edit mode within Bastion panes. Modal editing inspired by vi.

Development Tasks (☿ Nova)

  • Create hero/ module with text buffer (Rope based)
  • Implement insert/normal modal states
  • Add syntax highlighting hook (tree-sitter integration point)
  • Handle Unicode input (emoji, CJK, RTL) correctly
  • Undo/redo stack (min 100 operations, unlimited preferred)

Testing Criteria (☿ Nova)

  • Unicode insertion test: emoji, CJK characters render correctly
  • Modal state test: key maps correctly in insert vs normal mode
  • Undo chain: 100-step undo preserves all operations
  • Large file test: 10MB file opens in <500ms, scrolls smoothly
  • Memory test: no leaks during 1hr edit session

Completion Criteria (🜔 Claudian Review)

  • Mode toggle: Ctrl+E enters/exits edit mode from any widget
  • Status bar: shows current mode (INSERT/NORMAL) + cursor position
  • Undo persists until file close or explicit save
  • Documented: docs/hero.md with all keybindings

Blockers

  • #1 (Calendar Widget)
  • #2 (Clock Widget) - edit mode applies to all widgets
