Add component props and lambda event handlers (TDD)
Implements two major features using Test-Driven Development:
1. Component Props/Parameters:
- Components can accept parameters: @component def Button(label)
- Arguments passed when yielding: yield Button("Click me")
- Default values supported: def Tabs(orientation=0)
- Codegen passes arguments correctly to render functions
2. Lambda Event Handlers:
- Support onclick=lambda: function_call() syntax
- Parser converts lambdas to synthetic functions
- Synthetic functions auto-named: _lambda_0_ComponentName
- Codegen emits lambda functions as event handlers
- Clean syntax vs set_tab_0/1/2 boilerplate
Implementation:
- Added _process_lambdas_in_component() to scan & convert
- Lambda detection in _transform_expr()
- "expr" statement type for lambda bodies
- Component argument passing in _emit_yield_component()
- Constants vs variables handled correctly in args
Tests (TDD Style):
- test_component_props.py (8 tests) - all passing
- test_lambda_simple.py (3 tests) - all passing
- 46 total tests passing
Examples:
# Before (verbose)
def set_tab_0(): tab = 0
def set_tab_1(): tab = 1
with Button(onclick=set_tab_0): yield "Tab 0"
# After (clean)
with Button(onclick=lambda: set_tab(0)): yield "Tab 0"
with Button(onclick=lambda: set_tab(1)): yield "Tab 1"
