### 🚀 开始贡献

#### 1. 准备开发环境

```bash
# Fork 并克隆仓库
git clone https://github.com/your-username/LandPPT.git
cd LandPPT

# 创建虚拟环境
python -m venv .venv
source .venv/bin/activate  # Linux/Mac
# 或
.venv\Scripts\activate     # Windows

# 安装依赖
pip install uv
uv pip install -e ".[dev]"

# 配置环境变量
cp .env.example .env
# 编辑 .env 文件配置必要的API密钥

# 初始化数据库
python setup_database.py

# 运行项目
python run.py
```

#### 2. 开发流程

1. **创建分支**
   ```bash
   git checkout -b feature/your-feature-name
   # 或
   git checkout -b fix/your-bug-fix
   ```

2. **编写代码**
   - 遵循现有的代码风格
   - 添加必要的注释和文档字符串
   - 确保代码通过所有测试

3. **运行测试**
   ```bash
   # 运行所有测试
   pytest

   # 运行特定测试
   pytest tests/test_specific.py

   # 生成覆盖率报告
   pytest --cov=src/landppt
   ```

4. **代码格式化**
   ```bash
   # 格式化代码
   black src/
   isort src/

   # 检查代码质量
   flake8 src/
   mypy src/
   ```

5. **提交更改**

   ```

6. **推送并创建PR**
   ```bash
   git push origin feature/your-feature-name
   ```
   然后在GitHub上创建Pull Request

### 📝 代码规范

#### 提交信息格式
使用 [Conventional Commits](https://www.conventionalcommits.org/) 格式：

```
<type>[optional scope]: <description>

[optional body]

[optional footer(s)]
```

类型包括：
- `feat`: 新功能
- `fix`: Bug修复
- `docs`: 文档更新
- `style`: 代码格式化
- `refactor`: 代码重构
- `test`: 测试相关
- `chore`: 构建过程或辅助工具的变动

#### Python代码规范
- 遵循 [PEP 8](https://pep8.org/) 规范
- 使用类型提示 (Type Hints)
- 编写清晰的文档字符串
- 保持函数和类的单一职责

#### 示例代码风格
```python
from typing import Optional, Dict, Any
import logging

logger = logging.getLogger(__name__)

class PPTGenerator:
    """PPT生成器类
    
    负责根据输入内容生成PPT演示文稿
    """
    
    def __init__(self, config: Dict[str, Any]) -> None:
        """初始化PPT生成器
        
        Args:
            config: 配置字典
        """
        self.config = config
        
    async def generate_ppt(
        self, 
        content: str, 
        template_id: Optional[str] = None
    ) -> Dict[str, Any]:
        """生成PPT
        
        Args:
            content: 输入内容
            template_id: 模板ID，可选
            
        Returns:
            生成的PPT数据
            
        Raises:
            ValueError: 当输入内容为空时
        """
        if not content.strip():
            raise ValueError("内容不能为空")
            
        logger.info(f"开始生成PPT，内容长度: {len(content)}")
        
        # 实现逻辑...
        return {"status": "success", "data": {}}
```

### 🧪 测试指南

#### 编写测试
- 为新功能编写单元测试
- 确保测试覆盖率不低于80%
- 使用有意义的测试名称
- 测试边界条件和异常情况

#### 测试示例
```python
import pytest
from unittest.mock import Mock, patch
from src.landppt.core.ppt_generator import PPTGenerator

class TestPPTGenerator:
    """PPT生成器测试类"""
    
    @pytest.fixture
    def generator(self):
        """创建PPT生成器实例"""
        config = {"template_dir": "/tmp/templates"}
        return PPTGenerator(config)
    
    async def test_generate_ppt_success(self, generator):
        """测试成功生成PPT"""
        content = "这是测试内容"
        result = await generator.generate_ppt(content)
        
        assert result["status"] == "success"
        assert "data" in result
    
    async def test_generate_ppt_empty_content(self, generator):
        """测试空内容异常"""
        with pytest.raises(ValueError, match="内容不能为空"):
            await generator.generate_ppt("")
```
