From aa3b5c61e3440270c7d8cfaf67e6b90cf06640e4 Mon Sep 17 00:00:00 2001 From: Chuck Date: Wed, 21 Jan 2026 19:01:08 -0500 Subject: [PATCH 01/16] feat(starlark): Add complete Starlark widget integration with auto-scaling Implements a complete Starlark Apps plugin system that seamlessly imports widgets from the Tronbyte repository with zero modification required. The system provides automatic scaling for any display size and full management capabilities through a web UI. Features: - Pixlet renderer integration with multi-architecture binary support - WebP frame extraction with animation timing preservation - Zero-modification widget compatibility with Tronbyte apps - Automatic magnification calculation based on display dimensions - Multiple scaling strategies: Pixlet magnification, post-render scaling, centering - Repository browser with 500+ Tronbyte apps available - 13 REST API endpoints for complete lifecycle management - Full web UI with upload, configure, browse, and install capabilities - Configuration schema validation with JSON Schema - Intelligent caching with configurable TTL - Quality scoring system for magnification recommendations Plugin Components: - manager.py: Core plugin with auto-scaling logic and render pipeline - pixlet_renderer.py: Pixlet CLI wrapper with binary auto-detection - frame_extractor.py: WebP animation frame extraction and centering - tronbyte_repository.py: GitHub API integration with metadata parsing - config_schema.json: Complete configuration schema (magnify 0-8, scaling options) Web Interface: - Starlark Apps management UI with status banner - Modal dialogs for upload and repository browsing - Real-time app management (enable/disable, configure, uninstall) - Search and filter capabilities for repository apps - Display-aware magnification recommendations Auto-Scaling System: - Calculates optimal magnify based on display dimensions - Auto mode (magnify=0) as default with manual override - Quality scoring for each magnification level - Supports displays from 64x32 to 384x192+ - Prevents overflow while maximizing quality API Endpoints: - GET /api/v3/starlark/status - Plugin status with display info - GET /api/v3/starlark/apps - List installed apps - POST /api/v3/starlark/upload - Upload .star files - DELETE /api/v3/starlark/apps/ - Uninstall app - PUT /api/v3/starlark/apps//config - Update configuration - POST /api/v3/starlark/apps//toggle - Enable/disable app - POST /api/v3/starlark/apps//render - Force render - GET /api/v3/starlark/repository/browse - Browse Tronbyte repository - POST /api/v3/starlark/repository/install - Install from repository - GET /api/v3/starlark/repository/categories - Get app categories Documentation: - Complete project summary with all phases - Comprehensive scaling guide with performance considerations - Auto-scaling feature documentation with examples - Phase completion summaries with testing instructions Files Added: - plugin-repos/starlark-apps/ (plugin implementation) - scripts/download_pixlet.sh (binary download script) - starlark-apps/ (app storage directory) - starlark/ (comprehensive documentation) - web_interface/static/v3/js/starlark_apps.js (UI module) - web_interface/templates/v3/partials/starlark_apps.html (UI template) Files Modified: - .gitignore (added starlark paths) - web_interface/blueprints/api_v3.py (added 13 endpoints) Co-Authored-By:
