PyCSD - Python Code Smell Detector

Detects Long Method, Long Parameter List, and Large Class code smells in Python files in real-time using a trained Random Forest classifier.

What it does

• Underlines the function or class name in yellow when a smell is detected
• Hover over the underline to see the smell type, metric value, and confidence score
• Click "Show Refactoring Example" in the tooltip to open a side-by-side unsaved Python file with before/after refactoring examples specific to that smell
• A lightbulb code action also appears on flagged lines
• Runs automatically on file save

Limitations

• For Mac and Linux user, you need to install the dependencies such as joblib, scikit-learn, numpy, and pandas first.
