以下是一个完整的 Python 脚本，它： - 从标准输入（stdin）读取 Kotlin 源码（支持多行，以 `Ctrl+D` 结束）； - 根据你提出的 **两个要求**，分别生成两段新的 Kotlin 代码： - ✅ `ManagerImpl.kt`：实现类（`internal class XxxManagerImpl` + `IxxxManager` 接口 + `private val api = XxxApi(...)` + 函数体重写为委托调用）； - ✅ `ManagerInterface.kt`：接口定义（`interface IxxxManager`，仅函数签名，无函数体）； - 自动提取原始类名（如 `CustomerApi` → `Customer`），推导包名、导入路径、接口名等； - 严格保留原始函数参数顺序、默认值、返回类型、`suspend` 修饰符； - 处理 Kotlin 的换行缩进与格式（使用合理缩进，4空格）； - 支持常见泛型返回类型（如 `ApiResponse<CustomerResult>`）和复杂参数（含 `? = null`, `= 1` 等）； - 健壮处理边界情况：空输入、无类定义、无 package 行等（带提示）。 --- ### ✅ Python 脚本（可直接保存为 `gen_managers.py` 并运行） ```python #!/usr/bin/env python3 import sys import re from typing import List, Tuple, Optional, Dict, Any def parse_kotlin_class(content: str) -> Dict[str, Any]: """解析 Kotlin 文件，提取关键信息：package、class_name、functions、imports""" lines = [line.rstrip() for line in content.splitlines() if line.strip()] # 1. 提取 package package_match = re.search(r'^package\s+([\w.]+);?$', content, re.MULTILINE) package = package_match.group(1) if package_match else "com.tplink.omada.kmp.openapi.api" # 2. 提取 imports（所有 import 行） imports = [] for line in lines: if line.strip().startswith("import "): imports.append(line.strip()) # 3. 提取 class 定义（找 class XxxApi(...) {） class_def_match = re.search( r'class\s+([A-Za-z0-9]+)Api\s*\(([^)]*)\)\s*{', content, re.DOTALL ) if not class_def_match: raise ValueError("未找到 'class XxxApi(...)' 定义") original_class_name = class_def_match.group(1) # e.g., "Customer" constructor_params = class_def_match.group(2).strip() # 4. 提取所有 suspend fun 函数（匹配到 } 为止的完整函数块） fun_blocks = [] in_fun = False current_fun = [] brace_count = 0 fun_start_re = re.compile(r'^\s*suspend\s+fun\s+([A-Za-z0-9]+)\s*\(([^)]*)\)\s*:\s*([^={]+)(?:\s*=\s*|$)') # 更鲁棒：先找 fun 开头，再按 `{` `}` 计数抓完整块 i = 0 while i < len(lines): line = lines[i] if re.match(r'^\s*suspend\s+fun\s+[A-Za-z0-9]+\s*\(', line): # 找到函数开始 → 向下扫描直到匹配完 {} current_fun = [line] brace_count = line.count('{') -
