Tech Stack

  • Framework: Kivy 2.3.1
  • Language: Python 3.12+
  • Graphics: OpenGL ES 2.0
  • Platforms: iOS, Android, Desktop

Design Patterns

  • Command Pattern - Undo/redo functionality
  • Model-View - Separation of data and UI
  • Observer - Event-driven updates
  • Factory - Dialog creation

Key Components

  1. GraphCanvas - Low-level rendering and touch handling
  2. GraphScreen - High-level UI and interactions
  3. WTPApp - App lifecycle and state management
  4. GraphModel - Data structure and validation
  5. CommandHistory - Undo/redo stack

🔧 Development

Prerequisites

  • Python 3.12+
  • pip
  • virtualenv

Setup Development Environment

git clone <repo>
cd WTP-iOS-Kivy
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt  # Or: pip install kivy pillow

Run Tests

# Unit tests (desktop app tests - adapt for mobile)
cd ../tests
python -m pytest

Build for iOS

# Install Kivy-iOS

🧪 Testing

Test Suite

# Run all tests (70 tests)
pytest tests/ -v

# Run specific test categories
pytest tests/test_mobile.py -v    # Unit tests (52)
pytest tests/test_widgets.py -v   # Widget tests (18)

Test Coverage

  • ✅ Unit Tests: 52 tests - Core logic (model, commands, persistence, settings)
  • ✅ Widget Tests: 18 tests - UI behavior (minimap, touch events, state sync)
  • 🔜 Integration Tests: Cross-widget interactions (planned)
  • 🔜 UI Interaction Tests: Simulated user flows (planned)

Current Pass Rate: 100% (70/70 tests)

See TESTING_PLAN.md for detailed testing strategy.

🐛 Known Issues

Recently Fixed ✅

  1. Minimap Viewport - Viewport indicator now stays within bounds and tracks correctly
  2. Double-Click Artifacts - Added 300ms cooldown to prevent visual glitches

Minor Limitations

  1. No Pinch Zoom - Use toolbar buttons instead

    • Reason: Removed Scatter widget to fix touch handling
    • Workaround: ➕➖ zoom buttons work well

  2. No Multi-Select UI - Infrastructure exists but UI not added

    • Future: Can add Shift+Tap or lasso selection

  3. Duplicate Edge Error - Intentional validation

    • Shows error in status bar when attempting duplicate edge

🎯 Roadmap

Version 1.1 (Future)

  • Pinch-to-zoom gestures
  • Multi-select UI (Shift+Tap)
  • Export to PNG/PDF
  • Cloud sync (iCloud/Dropbox)
  • More themes

Version 1.2 (Future)

  • Templates library
  • Graph statistics
  • Animations
  • Plugin system

🤝 Contributing

This is a complete port of the desktop WTP app. The codebase is clean, well-documented, and ready for contributions.

Areas for Enhancement

  1. Pinch zoom implementation
  2. Multi-select UI
  3. Additional themes
  4. Cloud sync integration
  5. Export features
