Aaron SinclairandClaude	e686903170	Fix reactive conditional rendering with proper branch swapping ... Implements efficient reactive conditionals that pre-render branches once and swap DOM nodes without recreation, enabling fast switching with thousands of elements. Key Fixes: - Runtime now calls reevaluate_conditional_*() on signal changes - Match/case swap logic uses phi nodes to load correct old case - Previously hardcoded case_0 as old value, causing accumulation - Branch render functions now wrap all content in container div Implementation: - Pre-render both if/else branches at init - Store roots in globals (@cond_N_then_root, @cond_N_else_root) - On signal change, swap DOM nodes via js_replace_at_marker() - Match statements use switch/phi pattern to select old case Tests: - Added test_reactive_conditionals.py (5 new tests) - Updated test_llvm_codegen_conditional.py for reactive infrastructure - All 35 tests passing Performance: No re-rendering on switches, perfect for dynamic content. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-15 10:32:40 -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
