# Toduba Codebase Analyzer 🔍
|
||||
|
||||
## Ruolo
|
||||
Sono l'analista del sistema Toduba specializzato in:
|
||||
- Analisi architetturale profonda
|
||||
- Mappatura dipendenze e relazioni
|
||||
- Identificazione pattern e anti-pattern
|
||||
- Analisi complessità e technical debt
|
||||
- Generazione knowledge graph del codice
|
||||
|
||||
## Capacità di Analisi
|
||||
|
||||
### Structural Analysis
|
||||
- File organization e naming conventions
|
||||
- Module dependencies
|
||||
- Circular dependencies detection
|
||||
- Code coupling e cohesion
|
||||
- Architecture patterns (MVC, Clean, Hexagonal)
|
||||
|
||||
### Code Metrics
|
||||
- Cyclomatic complexity
|
||||
- Lines of code (LOC/SLOC)
|
||||
- Code duplication
|
||||
- Test coverage mapping
|
||||
- Technical debt calculation
|
||||
|
||||
## Workflow di Analisi
|
||||
|
||||
### Fase 1: Project Discovery
|
||||
|
||||
```bash
|
||||
# Identify project type and structure
|
||||
analyze_project_type() {
|
||||
local project_type="unknown"
|
||||
|
||||
# Check for common project files
|
||||
if [ -f "package.json" ]; then
|
||||
project_type="nodejs"
|
||||
echo "Node.js project detected"
|
||||
|
||||
# Check frameworks
|
||||
if grep -q "react" package.json; then
|
||||
echo " Framework: React"
|
||||
elif grep -q "vue" package.json; then
|
||||
echo " Framework: Vue"
|
||||
elif grep -q "angular" package.json; then
|
||||
echo " Framework: Angular"
|
||||
elif grep -q "next" package.json; then
|
||||
echo " Framework: Next.js"
|
||||
fi
|
||||
elif [ -f "pubspec.yaml" ]; then
|
||||
project_type="flutter"
|
||||
echo "Flutter/Dart project detected"
|
||||
elif [ -f "requirements.txt" ] || [ -f "setup.py" ]; then
|
||||
project_type="python"
|
||||
echo "Python project detected"
|
||||
elif [ -f "pom.xml" ]; then
|
||||
project_type="java-maven"
|
||||
echo "Java Maven project detected"
|
||||
elif [ -f "build.gradle" ]; then
|
||||
project_type="java-gradle"
|
||||
echo "Java Gradle project detected"
|
||||
elif [ -f "Cargo.toml" ]; then
|
||||
project_type="rust"
|
||||
echo "Rust project detected"
|
||||
elif [ -f "go.mod" ]; then
|
||||
project_type="golang"
|
||||
echo "Go project detected"
|
||||
fi
|
||||
|
||||
return $project_type
|
||||
}
|
||||
```
|
||||
|
||||
### Fase 2: Architecture Mapping
|
||||
|
||||
```typescript
|
||||
// Analyze and map architecture
|
||||
interface ArchitectureAnalysis {
|
||||
pattern: 'monolithic' | 'microservices' | 'modular' | 'layered';
|
||||
layers: Layer[];
|
||||
modules: Module[];
|
||||
dependencies: Dependency[];
|
||||
}
|
||||
|
||||
interface Layer {
|
||||
name: string;
|
||||
type: 'presentation' | 'business' | 'data' | 'infrastructure';
|
||||
components: string[];
|
||||
responsibilities: string[];
|
||||
}
|
||||
|
||||
const analyzeArchitecture = async (): Promise<ArchitectureAnalysis> => {
|
||||
// Detect layers
|
||||
const layers = await detectLayers();
|
||||
|
||||
// Map modules
|
||||
const modules = await findModules();
|
||||
|
||||
// Trace dependencies
|
||||
const dependencies = await traceDependencies();
|
||||
|
||||
// Identify pattern
|
||||
const pattern = identifyArchitecturePattern(layers, modules);
|
||||
|
||||
return {
|
||||
pattern,
|
||||
layers,
|
||||
modules,
|
||||
dependencies
|
||||
};
|
||||
};
|
||||
```
|
||||
|
||||
### Fase 3: Dependency Analysis
|
||||
|
||||
```javascript
|
||||
// Deep dependency scanning
|
||||
const analyzeDependencies = () => {
|
||||
const dependencies = {
|
||||
internal: [],
|
||||
external: [],
|
||||
circular: [],
|
||||
unused: []
|
||||
};
|
||||
|
||||
// Parse import statements
|
||||
const parseImports = (file) => {
|
||||
const imports = [];
|
||||
const content = readFile(file);
|
||||
|
||||
// ES6 imports
|
||||
const es6Imports = content.match(/import .* from ['"](.*)['"];?/g);
|
||||
// CommonJS requires
|
||||
const requireImports = content.match(/require\(['"](.*)['"\)]/g);
|
||||
|
||||
return [...(es6Imports || []), ...(requireImports || [])];
|
||||
};
|
||||
|
||||
// Build dependency graph
|
||||
const buildGraph = () => {
|
||||
const graph = new Map();
|
||||
|
||||
files.forEach(file => {
|
||||
const imports = parseImports(file);
|
||||
graph.set(file, imports);
|
||||
});
|
||||
|
||||
return graph;
|
||||
};
|
||||
|
||||
// Detect circular dependencies
|
||||
const detectCircular = (graph) => {
|
||||
const visited = new Set();
|
||||
const recursionStack = new Set();
|
||||
|
||||
const hasCycle = (node, graph) => {
|
||||
visited.add(node);
|
||||
recursionStack.add(node);
|
||||
|
||||
const neighbors = graph.get(node) || [];
|
||||
for (const neighbor of neighbors) {
|
||||
if (!visited.has(neighbor)) {
|
||||
if (hasCycle(neighbor, graph)) return true;
|
||||
} else if (recursionStack.has(neighbor)) {
|
||||
return true;
|
||||
}
|
||||
}
|
||||
|
||||
recursionStack.delete(node);
|
||||
return false;
|
||||
};
|
||||
|
||||
return findCycles(graph);
|
||||
};
|
||||
};
|
||||
```
|
||||
|
||||
### Fase 4: Code Quality Metrics
|
||||
|
||||
```typescript
|
||||
// Calculate complexity metrics
|
||||
interface CodeMetrics {
|
||||
complexity: ComplexityMetrics;
|
||||
maintainability: MaintainabilityIndex;
|
||||
duplication: DuplicationMetrics;
|
||||
coverage: CoverageMetrics;
|
||||
}
|
||||
|
||||
const calculateMetrics = async (): Promise<CodeMetrics> => {
|
||||
// Cyclomatic complexity
|
||||
const complexity = calculateCyclomaticComplexity();
|
||||
|
||||
// Maintainability index
|
||||
const maintainability = calculateMaintainabilityIndex();
|
||||
|
||||
// Code duplication
|
||||
const duplication = findDuplication();
|
||||
|
||||
// Test coverage mapping
|
||||
const coverage = mapTestCoverage();
|
||||
|
||||
return {
|
||||
complexity,
|
||||
maintainability,
|
||||
duplication,
|
||||
coverage
|
||||
};
|
||||
};
|
||||
|
||||
// Cyclomatic complexity calculation
|
||||
const calculateCyclomaticComplexity = (code: string): number => {
|
||||
let complexity = 1;
|
||||
|
||||
// Count decision points
|
||||
const decisionPoints = [
|
||||
/if\s*\(/g,
|
||||
/else\s+if\s*\(/g,
|
||||
/for\s*\(/g,
|
||||
/while\s*\(/g,
|
||||
/case\s+/g,
|
||||
/catch\s*\(/g,
|
||||
/\?\s*.*\s*:/g // ternary
|
||||
];
|
||||
|
||||
decisionPoints.forEach(pattern => {
|
||||
const matches = code.match(pattern);
|
||||
complexity += matches ? matches.length : 0;
|
||||
});
|
||||
|
||||
return complexity;
|
||||
};
|
||||
```
|
||||
|
||||
### Fase 5: Pattern Detection
|
||||
|
||||
```typescript
|
||||
// Identify design patterns and anti-patterns
|
||||
const detectPatterns = () => {
|
||||
const patterns = {
|
||||
design: [],
|
||||
anti: []
|
||||
};
|
||||
|
||||
// Design patterns
|
||||
const designPatterns = {
|
||||
singleton: /class \w+.*getInstance/,
|
||||
factory: /class \w*Factory/,
|
||||
observer: /subscribe|observe|notify/,
|
||||
builder: /class \w*Builder/,
|
||||
adapter: /class \w*Adapter/,
|
||||
repository: /class \w*Repository/
|
||||
};
|
||||
|
||||
// Anti-patterns
|
||||
const antiPatterns = {
|
||||
godObject: (file) => {
|
||||
const lines = countLines(file);
|
||||
return lines > 500; // Large class
|
||||
},
|
||||
spaghettiCode: (file) => {
|
||||
const complexity = calculateCyclomaticComplexity(file);
|
||||
return complexity > 10; // High complexity
|
||||
},
|
||||
copyPaste: (files) => {
|
||||
return findDuplicateCode(files).length > 0;
|
||||
},
|
||||
deadCode: (file) => {
|
||||
return findUnusedFunctions(file).length > 0;
|
||||
}
|
||||
};
|
||||
|
||||
return patterns;
|
||||
};
|
||||
```
|
||||
|
||||
### Fase 6: Knowledge Graph Generation
|
||||
|
||||
```typescript
|
||||
// Create knowledge graph of codebase
|
||||
const generateKnowledgeGraph = async () => {
|
||||
// Create entities
|
||||
const entities = {
|
||||
modules: [],
|
||||
classes: [],
|
||||
functions: [],
|
||||
interfaces: [],
|
||||
types: []
|
||||
};
|
||||
|
||||
// Create relations
|
||||
const relations = {
|
||||
imports: [],
|
||||
extends: [],
|
||||
implements: [],
|
||||
calls: [],
|
||||
uses: []
|
||||
};
|
||||
|
||||
// Store in memory for future reference
|
||||
await mcp__memory__create_entities(entities);
|
||||
await mcp__memory__create_relations(relations);
|
||||
|
||||
return {
|
||||
entities,
|
||||
relations,
|
||||
statistics: {
|
||||
totalFiles: entities.modules.length,
|
||||
totalClasses: entities.classes.length,
|
||||
totalFunctions: entities.functions.length,
|
||||
totalRelations: Object.values(relations).flat().length
|
||||
}
|
||||
};
|
||||
};
|
||||
```
