# Architecture : Intégrations IDE Profondes

## Vue d'ensemble

Cette architecture décrit l'implémentation d'intégrations IDE natives pour GestVenv, avec un focus initial sur VS Code. L'objectif est de fournir une expérience développeur transparente avec IntelliSense complet, gestion des environnements intégrée, et support des fonctionnalités avancées de GestVenv.

## Objectifs

### Principaux
- 🎯 **IntelliSense natif** pour tous les packages installés dans les environnements GestVenv
- 🔄 **Synchronisation bidirectionnelle** entre l'IDE et GestVenv
- 🚀 **Activation automatique** des environnements selon le contexte
- 📊 **Visualisation temps réel** de l'état des environnements
- 🔧 **Commandes intégrées** dans la palette de commandes

### Secondaires
- 💡 **Suggestions intelligentes** de packages basées sur les imports
- 🩺 **Diagnostics intégrés** avec quick fixes
- 📦 **Gestion visuelle** des dépendances et groupes
- 🔒 **Support des environnements éphémères** dans l'IDE

### 5. Interface utilisateur

#### Vue arborescente des environnements

```typescript

        placeHolder: 'Installation options'
      });
      
      await installPackageWithProgress(api, env, packageName, options);
    })
  );
}
```

#### Code Actions et Quick Fixes

```typescript
// src/providers/codeActionProvider.ts
export class GestVenvCodeActionProvider implements vscode.CodeActionProvider {
  constructor(private api: GestVenvAPI) {}
  
  async provideCodeActions(
    document: vscode.TextDocument,
    range: vscode.Range | vscode.Selection,
    context: vscode.CodeActionContext,
    token: vscode.CancellationToken
  ): Promise<vscode.CodeAction[]> {
    const actions: vscode.CodeAction[] = [];
    
    // Analyser les diagnostics
    for (const diagnostic of context.diagnostics) {
      if (diagnostic.code === 'missing-import') {
        actions.push(
          this.createInstallPackageAction(diagnostic)
        );
      }
      
      if (diagnostic.code === 'outdated-package') {
        actions.push(
          this.createUpdatePackageAction(diagnostic)
        );
      }
    }
    
    // Actions contextuelles
    const line = document.lineAt(range.start);
    
    // Sur une ligne d'import
    if (line.text.match(/^import\s+(\S+)|^from\s+(\S+)/)) {
      actions.push(
        this.createAddToRequirementsAction(line.text)
      );
    }
    
    return actions;
  }
  
  private createInstallPackageAction(
    diagnostic: vscode.Diagnostic
  ): vscode.CodeAction {
    const packageName = diagnostic.data?.packageName;
    const action = new vscode.CodeAction(
      `Install ${packageName}`,
      vscode.CodeActionKind.QuickFix
    );
    
    action.command = {
      command: 'gestvenv.installPackage',
      arguments: [packageName]
    };
    
    action.diagnostics = [diagnostic];
    action.isPreferred = true;
    
    return action;
  }
}
```

### 7. Synchronisation et Cache

#### Système de cache intelligent

```typescript
// src/cache/intelligentCache.ts
export class IntelligentCache {
  private memoryCache: Map<string, CacheEntry> = new Map();
  private diskCache: DiskCache;
  private cacheStats: CacheStatistics;
  
  constructor(private cacheDir: string) {
    this.diskCache = new DiskCache(cacheDir);
    this.cacheStats = new CacheStatistics();
  }
  
  async get<T>(key: string): Promise<T | null> {
    // Vérifier mémoire
    const memEntry = this.memoryCache.get(key);
    if (memEntry && !memEntry.isExpired()) {
      this.cacheStats.recordHit('memory');
      return memEntry.value;
    }
    
    // Vérifier disque
    const diskEntry = await this.diskCache.get(key);
    if (diskEntry && !diskEntry.isExpired()) {
      // Promouvoir en mémoire
      this.memoryCache.set(key, diskEntry);
      this.cacheStats.recordHit('disk');
      return diskEntry.value;
    }
    
    this.cacheStats.recordMiss();
    return null;
  }
  
  async set<T>(
    key: string, 
    value: T, 
    options: CacheOptions = {}
  ): Promise<void> {
    const entry = new CacheEntry(value, options);
    
    // Toujours en mémoire
    this.memoryCache.set(key, entry);
    
    // Disque si important ou gros
    if (options.persist || this.shouldPersist(value)) {
      await this.diskCache.set(key, entry);
    }
    
    // Éviction si nécessaire
    this.evictIfNeeded();
  }
  
  private shouldPersist(value: any): boolean {
    // Persister les données importantes
    const size = this.estimateSize(value);
    return size > 1024 * 10; // > 10KB
  }
  
  private evictIfNeeded() {
    const maxMemoryEntries = 1000;
    
    if (this.memoryCache.size > maxMemoryEntries) {
      // LRU eviction
      const entries = Array.from(this.memoryCache.entries());
      entries.sort((a, b) => a[1].lastAccess - b[1].lastAccess);
      
      // Supprimer les 20% les plus anciens
      const toRemove = Math.floor(entries.length * 0.2);
      for (let i = 0; i < toRemove; i++) {
        this.memoryCache.delete(entries[i][0]);
      }
    }
  }
}
```

### 8. Tests et Validation

#### Tests d'intégration

```typescript
// tests/integration/completion.test.ts
describe('GestVenv Completion Provider', () => {
  let provider: PythonCompletionProvider;
  let mockAPI: MockGestVenvAPI;
  
  beforeEach(() => {
    mockAPI = new MockGestVenvAPI();
    provider = new PythonCompletionProvider(mockAPI);
  });
  
  it('should provide import completions', async () => {
    // Setup
    mockAPI.setPackages([
      { name: 'requests', version: '2.28.0', modules: ['requests'] },
      { name: 'pandas', version: '1.5.0', modules: ['pandas'] }
    ]);
    
    const document = await vscode.workspace.openTextDocument({
      content: 'import ',
      language: 'python'
    });
    
    const position = new vscode.Position(0, 7);
    
    // Test
    const completions = await provider.provideCompletionItems(
      document,
      position,
      new vscode.CancellationTokenSource().token,
      { triggerKind: vscode.CompletionTriggerKind.Invoke }
    );
    
    // Assert
    expect(completions).toHaveLength(2);
    expect(completions[0].label).toBe('requests');
    expect(completions[0].detail).toBe('requests 2.28.0');
  });
  
  it('should provide attribute completions with caching', async () => {
    // Premier appel
    const completions1 = await provider.provideCompletionItems(...);
    expect(mockAPI.callCount).toBe(1);
    
    // Deuxième appel (depuis cache)
    const completions2 = await provider.provideCompletionItems(...);
    expect(mockAPI.callCount).toBe(1); // Pas d'appel supplémentaire
    expect(completions2).toEqual(completions1);
  });
});
```
