以下为 ​​HarmonyOS 5 CodeGenie AI结对编程协作模式的完整技术方案​​，包含实时建议生成、决策融合和上下文感知的代码级实现：

1. 协作架构设计

2. 核心协作模块

2.1 实时建议监听器

// suggestion-listener.ets
class CodeListener {
  private static lastCursorPos = 0;
  
  static setup() {
    editor.onDidChangeCursorPosition(pos => {
      if (Math.abs(pos - this.lastCursorPos) > 5) {
        this.lastCursorPos = pos;
        SuggestionEngine.triggerAt(pos);
      }
    });
  }
}

2.2 上下文感知器

// context-collector.ets
function getCodeContext(): CodeContext {
  return {
    fileType: editor.activeFile?.type,
    imports: parseImports(editor.activeText),
    nearbyCode: extractSurroundingCode(50), // 前后50行
    projectType: detectProjectType()
  };
}

3. 建议生成策略

3.1 智能补全生成

// completion-generator.ets
class CompletionEngine {
  static async generate(pos: Position): Promise<Suggestion[]> {
    const context = getCodeContext();
    const prefix = getPrefixAtPos(pos);
    
    return AI.predictCompletions({
      prefix,
      context,
      strategy: 'incremental'
    });
  }
}

3.2 错误修复建议

// error-fixer.ets
class ErrorFixer {
  static async suggestFixes(error: Error): Promise<FixSuggestion> {
    const similarFixes = await FixDB.querySimilar(error.message);
    const aiFixes = await AI.generateFixes(error.stack);
    
    return this.rankSuggestions([...similarFixes, ...aiFixes]);
  }
}

4. 决策仲裁机制

4.1 开发者偏好学习

// preference-learner.ets
class PreferenceModel {
  private static choices = new Map<string, number>();
  
  static recordChoice(suggestion: Suggestion, accepted: boolean) {
    const key = `${suggestion.type}-${suggestion.contentHash}`;
    this.choices.set(key, accepted ? 1 : -1);
  }
  
  static shouldSuggest(suggestion: Suggestion): boolean {
    const key = `${suggestion.type}-${suggestion.contentHash}`;
    return (this.choices.get(key) ?? 0) >= 0;
  }
}

4.2 建议优先级排序

// suggestion-ranker.ets
function rankSuggestions(suggestions: Suggestion[]): Suggestion[] {
  return suggestions
    .filter(s => PreferenceModel.shouldSuggest(s))
    .sort((a, b) => {
      const aScore = calculateRelevanceScore(a);
      const bScore = calculateRelevanceScore(b);
      return bScore - aScore;
    });
}

5. 智能合并策略

5.1 代码差异合并

// code-merger.ets
class SmartMerger {
  static merge(base: string, suggestion: string): string {
    const diff = createPatch('suggestion', base, suggestion);
    return applyPatch(base, diff, {
      fuzzFactor: 0.3 // 允许30%模糊匹配
    });
  }
}

5.2 冲突解决

// conflict-resolver.ets
function resolveConflict(original: string, aiSuggestion: string): string {
  const conflicts = detectConflicts(original, aiSuggestion);
  
  return conflicts.reduce((code, conflict) => {
    return keepOriginal(code, conflict.range);
  }, aiSuggestion);
}

6. 开发者交互设计

6.1 建议展示组件

// suggestion-ui.ets
@Component
struct SuggestionView {
  @Prop suggestions: Suggestion[];
  
  build() {
    Column() {
      ForEach(this.suggestions, (suggestion) => {
        SuggestionCard({
          suggestion,
          onAccept: () => acceptSuggestion(suggestion),
          onReject: () => rejectSuggestion(suggestion)
        })
      })
    }
  }
}

6.2 键盘快捷操作

// keybindings.ets
Keybindings.register({
  key: 'Tab',
  when: 'suggestionVisible',
  handler: (ctx) => {
    const topSuggestion = getTopSuggestion();
    acceptSuggestion(topSuggestion);
  }
});

7. 实时协作示例

7.1 开发者输入

// 开发者输入
function calculate(a: number, b: number): number {
  return a + 
  // 光标停在此处
}

7.2 AI建议生成

// 生成的建议列表
[
  { 
    type: 'completion',
    content: 'b', 
    confidence: 0.95 
  },
  { 
    type: 'method', 
    content: 'multiply(a, b)', 
    confidence: 0.82 
  }
]

7.3 决策合并结果

// 最终代码
function calculate(a: number, b: number): number {
  return a + b
}

8. 上下文保持机制

8.1 会话历史管理

// session-manager.ets
class CodingSession {
  private static history: SessionEvent[] = [];
  
  static record(event: SessionEvent) {
    this.history.push(event);
    if (this.history.length > 20) {
      this.history.shift();
    }
  }
  
  static getContext(): SessionContext {
    return {
      lastEvents: this.history.slice(-3),
      projectState: getProjectState()
    };
  }
}

8.2 长期记忆存储

// memory-manager.ets
class DeveloperMemory {
  static async recall(key: string): Promise<any> {
    return Database.query('developer_memory', {
      developerId: currentUser.id,
      key
    });
  }
  
  static async memorize(key: string, value: any) {
    await Database.insert('developer_memory', {
      developerId: currentUser.id,
      key,
      value: JSON.stringify(value)
    });
  }
}

9. 性能优化策略

9.1 建议缓存

// suggestion-cache.ets
class SuggestionCache {
  private static cache = new LRUCache<string, Suggestion[]>(100);
  
  static get(key: string): Suggestion[] | null {
    return this.cache.get(key);
  }
  
  static set(key: string, value: Suggestion[]) {
    this.cache.set(key, value);
  }
}

9.2 节流控制

// throttler.ets
class SuggestionThrottler {
  private static lastTrigger = 0;
  
  static canTrigger(): boolean {
    const now = Date.now();
    const delay = now - this.lastTrigger;
    this.lastTrigger = now;
    return delay > 500; // 500ms冷却
  }
}

10. 调试与分析工具

10.1 决策日志

// decision-logger.ets
class DecisionLogger {
  static logDecision(
    suggestion: Suggestion,
    action: 'accept' | 'reject'
  ) {
    console.table({
      timestamp: new Date(),
      suggestionHash: hashSuggestion(suggestion),
      action,
      context: getCodeContext()
    });
  }
}

10.2 性能分析

# 启动建议性能监控
codegenie-monitor --metric latency --threshold 200ms

11. 扩展开发接口

11.1 自定义建议器

// custom-suggester.ets
interface CustomSuggester {
  name: string;
  trigger: RegExp;
  suggest: (context: CodeContext) => Promise<Suggestion[]>;
}

SuggestionEngine.register({
  name: 'api-suggester',
  trigger: /fetch(['"]/,
  suggest: async (ctx) => {
    return APIRecommendation.get(ctx.nearbyCode);
  }
});

11.2 外部工具集成

// plugin-integration.ets
class ExternalToolAdapter {
  static async importSuggestions(tool: string) {
    const adapter = getAdapter(tool);
    return adapter.fetchSuggestions();
  }
}

12. 完整工作流示例

12.1 初始化配置

// init.ets
function setupPairProgramming() {
  CodeListener.setup();
  PreferenceModel.load();
  SuggestionEngine.init({
    maxSuggestions: 3,
    responseTime: 200
  });
}

12.2 实时协作循环

// event-loop.ets
editor.onDidChangeText(e => {
  if (SuggestionThrottler.canTrigger()) {
    const context = getCodeContext();
    const suggestions = await SuggestionEngine.generate(e.position);
    showSuggestions(rankSuggestions(suggestions));
  }
});

13. 关键性能指标

指标目标值测量方式
建议延迟<200ms输入到展示时间
接受率>65%接受数/总建议数
决策耗时<300ms建议展示到操作时间
内存占用<300MB建议缓存内存消耗

14. 安全与隐私

14.1 代码脱敏处理

// code-sanitizer.ets
function sanitizeForAI(code: string): string {
  return code.replace(
    /password\s*=\s*['"].+?['"]/g, 
    'password="******"'
  );
}

14.2 本地化处理

// local-processing.ets
class LocalAI {
  static processSensitive(context: CodeContext): Promise<Suggestion[]> {
    if (containsSensitiveData(context)) {
      return this.localModel.predict(context);
    }
    return CloudAI.predict(context);
  }
}

通过本方案可实现：

  1. ​​200ms内​​ 智能建议响应
  2. ​​上下文感知​​ 的精准推荐
  3. ​​可解释​​ 的决策过程
  4. ​​无缝​​ 开发者工作流集成
