Pyright Type Checking Issues in Visual Script¶

Dependency and Import Fixes¶

Install netifaces package
```
pip install netifaces
```

Verify import statement for netifaces

try:
    import netifaces
except ImportError:
    netifaces = None  # Graceful fallback

Type Annotation and Class Definition Fixes¶

Update CaptureResult dataclass to ensure all attributes are properly defined

@dataclass
class CaptureResult:
    page_name: str
    page_path: str
    status: CaptureStatus = CaptureStatus.PENDING
    screenshot_path: Optional[str] = None
    error_message: Optional[str] = None
    capture_duration: float = 0.0
    attempt_count: int = 0

Error Handling and Return Type Fixes¶

Refactor retry mechanism in screenshot capture methods

def _retry_screenshot_capture(
    self, 
    page_path: str, 
    max_attempts: int = 3
) -> CaptureResult:
    for attempt in range(max_attempts):
        try:
            result = await self.capture_screenshot_from_mkdocs_build(page_path)
            result.attempt_count = attempt + 1
            return result
        except Exception as e:
            if attempt == max_attempts - 1:
                return CaptureResult(
                    page_path=page_path,
                    page_name=page_path,
                    status=CaptureStatus.FAILED,
                    error_message=str(e)
                )

Parameter Type Fixes¶

Update method signatures to handle None for optional parameters

def capture_site_screenshots(
    self, 
    site_directory: str = 'site/', 
    exclude_dirs: Optional[List[str]] = []  # Default to empty list instead of None
) -> List[CaptureResult]:
    # Implementation remains the same

General Recommendations¶

Use type hints consistently
Implement proper error handling
Add logging for debugging
Consider using typing.Optional for nullable fields

Next Steps¶

Run Pyright after implementing these changes
Perform manual testing to ensure functionality
Update documentation to reflect type changes
