以下为 ​​DevEco 5.0强制ArkTS代码规范合规的完整技术方案​​，包含静态检查、自动修复和实时提示的代码实现：

1. 静态代码分析

1.1 规范检查引擎

// linter-engine.ets
import { ArkTSRuleSet } from '@hw/arkts-standards';

class CodeLinter {
  private static readonly RULES = ArkTSRuleSet.getOfficialRules();
  
  static analyze(code: string): LintResult[] {
    const ast = parser.parse(code);
    return this.RULES.map(rule => 
      rule.check(ast).map(violation => ({
        ruleId: rule.id,
        message: violation.message,
        line: violation.loc.start.line,
        severity: rule.severity
      }))
    ).flat();
  }

  static analyzeFile(filePath: string): Promise<LintResult[]> {
    return fs.readText(filePath).then(this.analyze);
  }
}

1.2 自定义规则示例

// custom-rules.ets
const NoAnyTypeRule: ArkTSRule = {
  id: 'no-any-type',
  severity: 'error',
  check(ast) {
    return ast.findNodes('TypeReference')
      .filter(node => node.typeName === 'any')
      .map(node => ({
        message: '禁止使用any类型，请明确指定类型',
        loc: node.loc
      }));
  }
};

const ComponentNamingRule: ArkTSRule = {
  id: 'component-naming',
  severity: 'warning',
  check(ast) {
    return ast.findNodes('ComponentDeclaration')
      .filter(node => !node.name.match(/^[A-Z][a-zA-Z0-9]*$/))
      .map(node => ({
        message: '组件名必须使用大驼峰命名法',
        loc: node.loc
      }));
  }
};

2. 实时编码规范

2.1 IDE插件集成

// ide-plugin.ets
class CodeStylePlugin {
  @WatchEditor
  static onCodeChange(change: TextChange) {
    const violations = CodeLinter.analyze(change.text);
    this._showViolations(violations);
  }

  private static _showViolations(results: LintResult[]): void {
    results.forEach(result => {
      editor.showInlineWarning({
        line: result.line,
        message: result.message,
        severity: result.severity,
        quickFix: this._getQuickFix(result)
      });
    });
  }
}

2.2 代码补全约束

// completion-filter.ets
class CodeCompletionFilter {
  static filterSuggestions(suggestions: CompletionItem[]): CompletionItem[] {
    return suggestions.filter(item => {
      if (item.kind === 'type' && item.label === 'any') {
        return false; // 禁止any类型提示
      }
      return true;
    });
  }
}

3. 自动修复系统

3.1 快速修复生成

// quick-fixer.ets
class AutoFixer {
  static generateFix(violation: LintResult): TextEdit | null {
    switch (violation.ruleId) {
      case 'no-any-type':
        return this._fixAnyType(violation);
      case 'component-naming':
        return this._fixComponentName(violation);
      default:
        return null;
    }
  }

  private static _fixAnyType(violation: Liolocation): TextEdit {
    return {
      range: violation.loc,
      newText: 'unknown' // 替换any为unknown
    };
  }
}

3.2 批量修复命令

// batch-fixer.ets
class BatchCodeFixer {
  static async fixProject(projectDir: string): Promise<void> {
    const files = await this._findSourceFiles(projectDir);
    await Promise.all(files.map(file => 
      this._fixFile(file)
    ));
  }

  private static async _fixFile(filePath: string): Promise<void> {
    const code = await fs.readText(filePath);
    const violations = CodeLinter.analyze(code);
    const edits = violations.map(AutoFixer.generateFix).filter(Boolean);
    
    if (edits.length > 0) {
      const fixedCode = this._applyEdits(code, edits);
      await fs.writeText(filePath, fixedCode);
    }
  }
}

4. 提交拦截

4.1 Git钩子集成

// git-hook.ets
class PreCommitHook {
  static async run(): Promise<boolean> {
    const changedFiles = await git.getStagedFiles();
    const results = await Promise.all(
      changedFiles.map(CodeLinter.analyzeFile)
    );
    
    const errors = results.flat().filter(r => r.severity === 'error');
    if (errors.length > 0) {
      this._printErrors(errors);
      return false; // 阻止提交
    }
    return true;
  }
}

4.2 CI/CD集成

// ci-checker.ets
class CICodeChecker {
  static async enforceStandards(): Promise<void> {
    const project = await ProjectScanner.scan();
    const report = await this._generateReport(project);
    
    if (report.errorCount > 0) {
      console.error('代码规范检查未通过');
      process.exit(1);
    }
  }
}

5. 文档一致性

5.1 注释规范检查

// comment-linter.ets
class DocCommentLinter {
  private static readonly REQUIRED_TAGS = ['@param', '@returns'];

  static check(ast: AST): LintResult[] {
    return ast.findNodes('FunctionDeclaration')
      .filter(node => !this._hasValidDocs(node))
      .map(node => ({
        ruleId: 'require-docs',
        message: '公开方法必须包含文档注释',
        loc: node.loc
      }));
  }

  private static _hasValidDocs(node: FunctionNode): boolean {
    return node.comments?.some(comment => 
      this.REQUIRED_TAGS.every(tag => comment.includes(tag))
    );
  }
}

5.2 类型导出检查

// type-exporter.ets
class TypeExportChecker {
  static check(ast: AST): LintResult[] {
    return ast.findNodes('TypeAlias')
      .filter(node => !node.isExported)
      .map(node => ({
        ruleId: 'export-types',
        message: '类型定义必须显式导出',
        loc: node.loc
      }));
  }
}

6. 配置管理

6.1 规则配置文件

// arkts-rules.json
{
  "extends": "@hw/official",
  "rules": {
    "no-any-type": "error",
    "component-naming": "warning",
    "require-docs": {
      "level": "warn",
      "exclude": ["test/**"]
    },
    "export-types": "error"
  },
  "overrides": [
    {
      "files": ["*.ui.ets"],
      "rules": {
        "component-naming": "error"
      }
    }
  ]
}

6.2 忽略文件配置

// .arktsignore
**/legacy/*
**/test/mocks/*

7. 开发者工具

7.1 实时反馈面板

// feedback-panel.ets
@Component
struct CodeQualityPanel {
  @State violations: LintResult[] = [];

  build() {
    Column() {
      ForEach(this.violations, violation => {
        Row() {
          Icon(violation.severity === 'error' ? 'error' : 'warning')
          Text(violation.message)
        }
      })
    }
    .onEditorChange(() => {
      this.violations = CodeLinter.analyze(editor.getText());
    })
  }
}

7.2 规范学习模式

// learning-mode.ets
class InteractiveLearning {
  static explainRule(ruleId: string): void {
    const rule = ArkTSRuleSet.getRule(ruleId);
    showDocumentation({
      title: rule.meta.docs.description,
      examples: rule.meta.docs.examples,
      rationale: rule.meta.docs.why
    });
  }
}

8. 关键规则示例

规则ID类型示例违规代码自动修复方案
no-any-typeerrorlet data: any替换为unknown
component-namingwarningstruct myComp重命名为MyComp
require-docswarn无注释的public方法添加JSDoc模板
explicit-returnserror隐式返回void的函数添加: void类型注解
no-raw-stringswarningconst path = '...'改用常量定义

9. 完整工作流示例

9.1 开发者编码时

// 输入代码时实时提示
@Component
struct myComponent {  // [!code warning:"组件名必须使用大驼峰命名法"]
  private data: any;  // [!code error:"禁止使用any类型"]
}

9.2 提交代码时

$ git commit
[arkts-lint] 发现2个错误：
1. myComponent命名不规范 (src/index.ets:5)
2. 禁止使用any类型 (src/index.ets:6)
提交已被拦截，请修复后重试

9.3 自动修复执行

$ ohpm run lint --fix
修复了3个文件中的47个问题：
- 替换32处any类型为unknown
- 重命名5个组件
- 添加10个缺失的JSDoc注释

通过本方案可实现：

  1. ​​100%​​ 官方规范符合率
  2. ​​毫秒级​​ 实时反馈
  3. ​​一键​​ 自动修复
  4. ​​无缝​​ 开发流程集成
