Project description

mutobj

Python 3.11+ License: MIT

mutobj (Mutable Object Declaration) - 支持声明与实现分离的 Python 类定义库。

特性

  • 声明与实现分离 - 类似 C/C++ 头文件模式
  • Extension 机制 - 为类添加私有状态而不污染接口
  • IDE 友好 - 完整支持 mypy/pyright 和 IDE 跳转
  • 继承支持 - 完整的类继承和方法覆盖
  • 零依赖 - 纯 Python 实现,无外部依赖

安装

pip install mutobj

快速开始

声明文件 (user.py)

import mutobj

class User(mutobj.Declaration):
    name: str
    age: int

    def greet(self) -> str:
        """返回问候语"""
        ...

实现文件 (user_impl.py)

import mutobj
from .user import User

@mutobj.impl(User.greet)
def greet(self: User) -> str:
    return f"Hello, I'm {self.name}!"

使用

from user import User
import user_impl  # 导入以注册实现

user = User(name="Alice", age=25)
print(user.greet())  # "Hello, I'm Alice!"

Extension 机制

为类添加私有状态:

class UserExt(mutobj.Extension[User]):
    _login_count: int = 0

    def __extension_init__(self):
        self._login_count = 0

@mutobj.impl(User.greet)
def greet(self: User) -> str:
    ext = UserExt.of(self)
    ext._login_count += 1
    return f"Hello, {self.name}! (login #{ext._login_count})"
