Metadata

  • Commit message: feat: implement TUI sidebar hidden visible fullscreen state transitions
  • Branch name: feat/tui-sidebar-state-transitions

Background and Context

The v3.7.0 TUI requires a sidebar with 3 states: hidden, visible, and fullscreen. The sidebar is the primary navigation panel for the TUI. State transitions must be smooth and triggered by keyboard shortcuts. ADR-044 defines the sidebar state machine.

The sidebar is a core UX element that enables users to navigate between different sections of the TUI efficiently. The 3-state model (hidden/visible/fullscreen) provides flexibility for different workflows and screen sizes.

Current Behavior

No sidebar exists. No state management for sidebar visibility.

Expected Behavior

Sidebar renders in 3 states: hidden (0 width), visible (configurable width), fullscreen (full terminal width). State transitions are triggered by keyboard shortcuts. Sidebar state persists across TUI sessions.

Acceptance Criteria

  • Sidebar renders in hidden state (0 width)
  • Sidebar renders in visible state (configurable width)
  • Sidebar renders in fullscreen state (full terminal width)
  • State transitions triggered by keyboard shortcuts
  • Sidebar state persists across TUI sessions
  • Smooth animation between states (if Textual supports it)
  • Test coverage >= 97% for sidebar state management

Subtasks

  • Implement sidebar widget with 3 state modes
  • Implement keyboard shortcut bindings for state transitions
  • Implement sidebar state persistence
  • Write widget tests for sidebar state transitions

Definition of Done

Sidebar has 3 states with keyboard-triggered transitions, state persists, and test coverage >= 97%.
