Development Workflow

Running the Web App

# Start local server
python3 serve-app.py

# Or use simple HTTP server
cd app
python3 -m http.server 8000

# Access at: http://localhost:8000

MIDI Bridge (Optional)

# Enable external MIDI control
python3 minimal-midi-bridge.py

Documentation Updates

# Update documentation
node docs-maintenance.js

Algorithm Reference

The WebApp contains the canonical implementations of all algorithms used in the plugin. When developing the plugin, always reference these implementations for accuracy:

Core Files

Key Functions

// Euclidean patterns
EuclideanRhythm.generate(onsets, steps, rotation)

// Barlow transformations  
BarlowTransformer.transform(pattern, targetOnsets)

// Progressive stepping
ProgressiveTransformer.step(currentPattern, algorithm, direction)

// UPI parsing
UPIParser.parse(upiString)

Browser Compatibility

Required Web APIs

Documentation Files

Shared Documentation (in this directory)

Usage

These documentation files are shared between the WebApp and Plugin projects, providing unified documentation for both implementations.

Testing

Manual Testing

  1. Open app/index.html in browser
  2. Test pattern generation: E(3,8), P(5,12)
  3. Test progressive transformations: E(1,8)E>8
  4. Verify audio playback and MIDI output
  5. Test complex combinations and edge cases

Algorithm Validation

The WebApp serves as the reference implementation for validating plugin algorithms. All pattern outputs should match between WebApp and Plugin versions.

Deployment

GitHub Pages

The WebApp can be deployed to GitHub Pages for public access:

# Push to gh-pages branch
git subtree push --prefix=WebApp/app origin gh-pages

Local Hosting

# Production server
python3 serve-app.py --host 0.0.0.0 --port 8080

Plugin Integration

Algorithm Synchronization

The Plugin implementation should always match the WebApp algorithms:

  1. Reference: WebApp implementations
  2. Port: Convert JavaScript to C++
  3. Validate: Ensure identical outputs
  4. Test: Cross-verify pattern generation

Shared Concepts

Development History

Original Implementation

The WebApp was the original implementation of Rhythm Pattern Explorer, developed over several years with extensive research into:

Evolution to Plugin

The Plugin version was developed based on the mature WebApp algorithms, ensuring:
