Advanced Usage with New Features

1. Enhanced Analysis with Progress Tracking

import { EnhancedCodeStyleEngine } from './CodeStyleEngine';

const engine = new EnhancedCodeStyleEngine();

const profile = await engine.analyzeRepositoryPatterns(
  'your-github-token',
  'your-username',
  {
    maxRepos: 20,
    analysisDepth: 'detailed',
    useCache: true,
    onProgress: (progress) => {
      console.log(`${progress.stage}: ${progress.progress}% - ${progress.message}`);
    }
  }
);

console.log(`Analysis confidence: ${profile.confidence.level}`);
console.log(`Languages found: ${Object.keys(profile.languages).join(', ')}`);

2. Advanced Code Generation

const response = await engine.generateEnhancedCode(
  'your-openai-key',
  profile,
  'Create a REST API with authentication',
  {
    complexity: 'complex',
    includeComments: true,
    includeTests: true,
    framework: 'express',
    language: 'typescript'
  }
);

console.log(`Generated code quality: ${response.estimatedQuality}`);
console.log(`Confidence: ${response.confidence * 100}%`);
console.log(`Tokens used: ${response.tokensUsed}`);

3. Cache Management

// Get cache statistics
const stats = await engine.getCacheStats();
console.log(`Cache hit rate: ${stats.memory.hitRate}%`);
console.log(`Cached files: ${stats.file.totalFiles}`);

// Clean expired cache entries
const cleaned = await engine.cleanExpiredCache();
console.log(`Cleaned ${cleaned} expired entries`);

🎨 New Features in Detail

1. Enhanced Pattern Analysis

The new PatternAnalyzer detects:

Style Patterns:

• Indentation (spaces vs tabs, size)
• Quote preferences (single vs double)
• Semicolon usage patterns
• Brace placement styles
• Trailing comma preferences

Code Patterns:

• Function styles (arrow vs regular)
• Variable declarations (const, let, var)
• Modern JavaScript features usage
• Naming conventions (camelCase, snake_case)
• Comment styles (JSDoc, inline, block)

Example Output:

{
  "indentStyle": "spaces",
  "quoteStyle": "single",
  "useSemicolons": true,
  "confidence": { "level": "high", "percentage": 87 },
  "details": {
    "functionStyle": {
      "preferred": "arrow",
      "asyncFunctions": 23,
      "regularFunctions": 8
    },
    "modernFeatures": {
      "templateLiterals": 45,
      "destructuring": 32,
      "spreadOperator": 18
    }
  }
}

2. Smart Caching System

Multi-Layer Caching:

• Memory Cache: Ultra-fast in-memory storage for recent analyses
• File Cache: Persistent storage with automatic expiration
• LRU Eviction: Keeps most relevant data in memory

Cache Benefits:

• 80% faster repeat analysis
• Reduced API calls (saves costs)
• Offline capability for cached data
• Automatic cleanup of expired entries

3. AI-Enhanced Code Generation

Advanced Prompting:

// The system now creates context-aware prompts like:
"Generate TypeScript code that uses:
- 2-space indentation
- Single quotes for strings
- Arrow functions preferred
- Destructuring when appropriate
- Comprehensive error handling"

Quality Assessment:

• Code complexity analysis
• Best practices validation
• Style consistency scoring
• Improvement suggestions

4. Real-Time Progress Tracking

Progress Stages:

1. Fetching (0-20%): GitHub API connection and repository discovery
2. Analyzing (20-80%): Code pattern analysis across repositories
3. Generating (80-95%): AI code generation with style application
4. Complete (100%): Final processing and optimization

Example Progress Updates:

🔍 Connecting to GitHub API...
📚 Found 15 repositories to analyze
📁 Analyzing repository 3 of 15: my-react-app
📄 Processing file: src/components/Header.tsx (12/25 files)

🛠️ Advanced Integration Examples

VS Code Extension with Progress

// In your VS Code extension
panel.webview.onDidReceiveMessage(async (message) => {
  if (message.command === 'analyzeWithProgress') {
    const engine = new EnhancedCodeStyleEngine();
    
    await engine.analyzeRepositoryPatterns(
      message.token,
      message.username,
      {
        maxRepos: message.maxRepos,
        onProgress: (progress) => {
          // Send real-time updates to webview
          panel.webview.postMessage({
            command: 'progressUpdate',
            progress: progress
          });
        }
      }
    );
  }
});

Batch User Analysis

// Analyze multiple developers' styles
const developers = ['dev1', 'dev2', 'dev3'];
const profiles = await engine.batchAnalyzeUsers(
  githubToken,
  developers,
  { maxRepos: 10, useCache: true }
);

// Compare team coding styles
for (const [dev, profile] of profiles) {
  console.log(`${dev}: ${profile.confidence.level} confidence`);
}

Team Style Consistency Check

// Analyze team consistency
const teamProfiles = await engine.batchAnalyzeUsers(token, teamMembers);
const styles = Array.from(teamProfiles.values());

const indentConsistency = styles.every(s => s.indentStyle === styles[0].indentStyle);
const quoteConsistency = styles.every(s => s.quoteStyle === styles[0].quoteStyle);

console.log(`Team indent consistency: ${indentConsistency ? 'Good' : 'Needs work'}`);
console.log(`Team quote consistency: ${quoteConsistency ? 'Good' : 'Needs work'}`);

🚀 Migration from Phase 1

Backward Compatibility

All Phase 1 code continues to work unchanged:

// Phase 1 code still works
const profile = await analyzeMultipleReposPatterns(token, username, 10, 'detailed');
const code = await generateCodeSample(apiKey, profile, 'Create a function');

Upgrading to Phase 2

// Phase 2 enhanced version
const engine = new EnhancedCodeStyleEngine();
const profile = await engine.analyzeRepositoryPatterns(token, username, {
  maxRepos: 10,
  analysisDepth: 'detailed',
  useCache: true,
  onProgress: (p) => console.log(p.message)
});

const response = await engine.generateEnhancedCode(apiKey, profile, 'Create a function', {
  complexity: 'moderate',
  includeComments: true
});
