Implementation Reference
- src/tools/refactoringSuggester.ts:6-56 (handler)Core handler function `suggestRefactoring` that orchestrates analysis for performance, readability, maintainability, and language-specific refactoring suggestions, generating prioritized suggestions.
export async function suggestRefactoring( code: string, language: string, focus: 'performance' | 'readability' | 'maintainability' | 'all' = 'all' ): Promise<RefactoringResult> { const suggestions: RefactoringSuggestion[] = []; // 根据重构重点进行分析 if (focus === 'all' || focus === 'performance') { await analyzePerformanceIssues(code, language, suggestions); } if (focus === 'all' || focus === 'readability') { await analyzeReadabilityIssues(code, language, suggestions); } if (focus === 'all' || focus === 'maintainability') { await analyzeMaintainabilityIssues(code, language, suggestions); } // 语言特定重构建议 switch (language.toLowerCase()) { case 'javascript': case 'typescript': await analyzeJavaScriptRefactoring(code, suggestions); break; case 'python': await analyzePythonRefactoring(code, suggestions); break; case 'java': await analyzeJavaRefactoring(code, suggestions); break; } // 按优先级排序 suggestions.sort((a, b) => { const priorityOrder = { 'high': 3, 'medium': 2, 'low': 1 }; return priorityOrder[b.priority] - priorityOrder[a.priority]; }); return { language, focus, totalSuggestions: suggestions.length, highPriority: suggestions.filter(s => s.priority === 'high').length, mediumPriority: suggestions.filter(s => s.priority === 'medium').length, lowPriority: suggestions.filter(s => s.priority === 'low').length, suggestions, summary: generateRefactoringSummary(suggestions, focus) }; } - src/types/index.ts:61-82 (schema)TypeScript interfaces defining the input/output structure for refactoring results: RefactoringResult and RefactoringSuggestion.
export interface RefactoringResult { language: string; focus: 'performance' | 'readability' | 'maintainability' | 'all'; totalSuggestions: number; highPriority: number; mediumPriority: number; lowPriority: number; suggestions: RefactoringSuggestion[]; summary: string; } export interface RefactoringSuggestion { type: 'performance' | 'readability' | 'maintainability' | 'modernization' | 'pythonic'; priority: 'high' | 'medium' | 'low'; title: string; description: string; line: number; originalCode: string; suggestedCode: string; impact: string; effort: 'low' | 'medium' | 'high'; } - src/index.ts:107-129 (registration)MCP tool registration in the server's listTools handler, specifying name, description, and JSON schema for input parameters.
