This commit completes the self-hosting of Ritz's debug console and
introduces the @external decorator for elegant JavaScript bridge functions.
## Major Features
### 1. Self-Hosted Debug Console (DebugConsole.py)
- Entire debug console UI written in Ritz itself
- Signal-based state management for toggle functionality
- Displays runtime stats (memory, signals, DOM nodes, logs)
- Live reactive updates when signals change in main app
- Keyboard shortcut support (Ctrl+`)
### 2. @external Decorator for JavaScript Bridges
- Pythonic decorator syntax: @external or @bridge
- Parser automatically recognizes and tracks external functions
- Codegen emits proper LLVM declarations
- No more hacky string checks (startswith("js_"))
- Clean, declarative bridge function definitions
Example:
```python
@external
def js_toggle_debug_console():
pass
def toggle():
js_toggle_debug_console() # Clean call to JS bridge
```
### 3. Enhanced RitzLoader Debug Mode
- `new RitzLoader({ debug: true })` auto-loads DebugConsole.wasm
- Keyboard shortcut registration (Ctrl+` toggle)
- Runtime stats injection (memory, signals, DOM nodes)
- Automatic status element hiding when debug enabled
- Debug console isolated in separate WASM runtime
## Bug Fixes
- Fixed reactive text node scoping (prevent global name collisions)
- Fixed CSS specificity for debug console status (use #ritz-debug)
- Fixed signal cross-contamination between runtimes (scope to rootElement)
- Fixed parser to handle expression statements in function bodies
- Fixed conditional branch rendering (append children to wrapper divs)
## Infrastructure Improvements
- Added H4 and Pre elements to syntax.py
- Parser handles @external decorator on top-level functions
- Codegen pre-collects external functions before emitting declarations
- Runtime scopes querySelector to prevent cross-runtime interference
- Debug stats update reactively on every signal change
## Files Added/Modified
New files:
- examples/runtime/DebugConsole.py - Self-hosted debug UI
- examples/runtime/DebugConsole.wasm - Compiled debug console (1.8KB)
- PHASE4_CLEANUP.md - Next phase planning document
Modified:
- ritz/parser.py - @external decorator support
- ritz/llvm_codegen_signals.py - External function handling
- ritz/syntax.py - Added external/bridge decorators, H4, Pre
- examples/runtime/ritz-runtime.js - Debug mode, stats updates
- examples/runtime/styles.css - Merged debug styles
- examples/template.html - Debug mode enabled by default
- examples/highfive/HighFive.html - Simplified using template
## Known Issues (Addressed in PHASE4_CLEANUP.md)
1. Debug console shifts page RIGHT (should shift LEFT)
2. Toggle implementation un-Ritzy (calls JS to manipulate DOM)
- Should use reactive class binding + @event decorator
- Needs event object bridge for keyboard events
3. Missing test infrastructure
## Next Steps (Phase 4)
See PHASE4_CLEANUP.md for detailed plan:
- Implement reactive class binding (signal-driven classes)
- Add @event decorator for declarative event registration
- Build event object bridge (access event.key, event.ctrlKey)
- Create Python test mode (execute without browser)
- Add comprehensive test suite
- Update all examples to use new patterns
