Overview

The Code Refactoring Advisor is an enterprise-grade code quality tool that analyzes Python and Solidity code to detect smells, anti-patterns, and complexity issues with actionable refactoring recommendations. It combines pattern detection, complexity metrics, and test generation to improve code quality systematically.

Key capabilities:

• Code Smell Detection: 12+ patterns (god functions, long parameters, deep nesting, etc.)
• Complexity Analysis: Cyclomatic complexity and maintainability index calculation
• Refactoring Recommendations: Specific solutions with code examples and effort estimates
• Test Generation: Automatic unit and integration test case generation
• Security Patterns: Solidity vulnerability detection (reentrancy, arithmetic, etc.)

Module Details

Module 1: Pattern Detector (92% Confidence)

Detects code smells and anti-patterns in Python and Solidity:

• Python: God functions, long parameter lists, deep nesting, bare excepts, global variables, magic numbers
• Solidity: Reentrancy vulnerabilities, unbounded loops, unchecked arithmetic, unclear visibility
• Outputs: Severity levels (CRITICAL/HIGH/MEDIUM/LOW), confidence scores, line numbers

Module 2: Refactoring Suggester (88% Confidence)

Generates specific refactoring solutions:

• Pattern-based recommendations (extract method, parameter object, strategy pattern, etc.)
• Effort estimates (TRIVIAL to LARGE)
• Benefits per refactoring (testability, maintainability, security, etc.)
• Code examples showing before/after

Module 3: Complexity Analyzer (90% Confidence)

Calculates code metrics:

• Cyclomatic complexity per function
• Maintainability Index (0-100)
• Code statistics (lines, comments, ratio)
• Health scoring and improvement recommendations

Module 4: Test Generator (85% Confidence)

Creates test cases for refactored code:

• Unit tests (extracted methods, parameters, guards)
• Integration tests (combined functionality)
• Security tests (reentrancy, edge cases)
• Test templates and strategies

Usage Examples

Detect Code Smells

from scripts.pattern_detector import PatternDetector

detector = PatternDetector()
result = detector.analyze_code(source_code, language="python")
print(f"Smells found: {result['smells_detected']}")
print(f"Code quality: {result['code_quality']}%")

Get Refactoring Recommendations

from scripts.refactoring_suggester import RefactoringSuggester

suggester = RefactoringSuggester()
suggestions = suggester.suggest_refactoring(smell_data)
for suggestion in suggestions['suggestions']:
    print(f"{suggestion['smell_type']}: {suggestion['solutions']}")

Analyze Complexity

from scripts.complexity_analyzer import ComplexityAnalyzer

analyzer = ComplexityAnalyzer()
metrics = analyzer.analyze_module(source_code)
print(f"Maintainability: {metrics['maintainability_index']['rating']}")

Generate Tests

from scripts.test_generator import TestGenerator

generator = TestGenerator()
tests = generator.generate_tests(refactoring_suggestions)
for test in tests['test_cases']:
    print(f"Test: {test['name']}")
