Aaron SinclairandClaude	1575571f3e	Implement reactive attributes for minimal DOM updates ... Features: - Track attributes that depend on signals (ternary expressions) - Store element references in globals for reactive attributes - Re-evaluate and update only changed attributes when signals change - Similar to reactive conditionals but for attributes Performance: - Minimal DOM updates - only changed attributes are updated - No full re-renders, no virtual DOM diffing - Direct attribute updates via js_set_attribute Example: class_='tab active' if tab_index == 0 else 'tab' When tab_index changes, only the class attribute updates. Implementation: - Collection phase: scan for attributes with signal dependencies - Render phase: store element references to globals - Signal update: re-evaluate expression and update attribute All tests passing (55 passed, 2 skipped) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-15 11:23:09 -08:00
Aaron SinclairandClaude	b0e38db22c	Fix nested components - render functions now return i32 ... Changes: - Component render functions return i32 (root element) instead of void - Nested components (yield SomeComponent()) now work correctly - Added main() entry point that calls top-level component and sets root - Updated runtime to call main() instead of render_ComponentName() Note: Active state in ternary expressions still needs reactive updates This commit fixes the nested component rendering issue All tests passing (51 passed, 2 skipped) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-15 11:16:23 -08:00
Aaron Sinclair	74ff1e7e9f	Support multiple components in single file with scoped signals ... - Update generate_llvm_ir() to accept list of component dicts - Process each component with own signal/handler state - Scope signal globals with component name prefix (@signal_ComponentName_signalName) - Add _signal_global() helper for scoped signal names - Update tests for scoped signal names - All tests passing (30/30)	2025-11-15 03:32:38 -08:00
Aaron Sinclair	044eda2293	Implement basic if statement rendering in LLVM IR ... - Add _emit_if() method to handle if statements - Add _emit_expr() to evaluate signal references and constants - Create basic blocks for then/else/merge - Convert condition to i1 and branch - Test passing: test_if_statement_codegen	2025-11-15 03:28:44 -08:00

Aaron Sinclair	635d466874	Implement Python → LLVM IR → WASM reactive framework ... 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!	2025-11-15 01:50:40 -08:00
