MAJOR ACHIEVEMENT: Full working reactive framework! ## What's Working ✅ Python → AST → Ritz IR → LLVM IR → WASM pipeline ✅ Reactive signals stored in WASM memory (@signal_name = global i32) ✅ Event handlers exported from WASM and callable from JS ✅ Clean runtime with RitzLoader and debug tools ✅ Two working examples: HelloWorld and HighFive counter ## Core Components ### Parser (ritz/parser.py) - Uses Python's ast module to parse components - Handles @component decorator, signals, event handlers - Supports yield, with statements, f-strings, augmented assignment (+=) - Clean syntax: from ritz.syntax import * ### LLVM IR Code Generator (ritz/llvm_codegen_signals.py) - Generates LLVM IR directly (not C!) - Signals as global variables in WASM memory - Exports getter/setter functions for each signal - Exports event handler functions for JS to call - UTF-8 string handling ### Build System (ritz/build.py) - Python → AST → IR → LLVM IR → clang --target=wasm32 → WASM - Saves intermediate .ll files for inspection - Debug symbols support (-g flag) ### Runtime (runtime/ritz-runtime.js) - RitzRuntime class: DOM bridge for WASM - RitzLoader class: Simplified component loading - Debug bar with Ctrl+` toggle - Signal updates trigger DOM updates ## Examples ### HelloWorld.py Simple static content - renders <p>Hello World</p> ### HighFive.py Reactive counter with: - Signal in WASM memory (high_fives = signal(0)) - Event handler (increment function) - DOM updates on signal change ## Test Coverage - 4 parser tests (all passing) - 4 LLVM codegen tests (all passing) - 4 signal parsing tests (all passing) - Code formatted with black and ruff ## Next Steps - <script type="text/ritz"> in-browser compilation - Better signal-to-DOM binding tracking - More complex examples (TodoMVC, forms, lists) - Playwright browser tests --- This is a genuinely innovative framework: write Python, compile to WASM, run with reactive signals in WASM memory. No virtual DOM, no transpilation, just compiled Python with fine-grained reactivity. 🎉 Python → WASM → Reactive UI is REAL!
