# 代码风格指南

## 代码格式化工具

本项目使用 clang-format 工具来统一代码风格。我们已经在项目根目录下提供了 `.clang-format` 配置文件,该配置基于 Google C++ 风格指南,并做了一些自定义调整。

### 安装 clang-format

在使用之前,请确保你已经安装了 clang-format 工具:

- **Windows**:
```powershell
winget install LLVM
# 或者使用 Chocolatey
choco install llvm
```

- **Linux**:
```bash
sudo apt install clang-format # Ubuntu/Debian
sudo dnf install clang-tools-extra # Fedora
```

- **macOS**:
```bash
brew install clang-format
```

### 使用方法

1. **格式化单个文件**:
```bash
clang-format -i path/to/your/file.cpp
```

2. **格式化整个项目**:
```bash
# 在项目根目录下执行
find main -iname *.h -o -iname *.cc | xargs clang-format -i
```

3. **在提交代码前检查格式**:
```bash
# 检查文件格式是否符合规范(不修改文件)
clang-format --dry-run -Werror path/to/your/file.cpp
```

### IDE 集成

- **Visual Studio Code**:
1. 安装 C/C++ 扩展
2. 在设置中启用 `C_Cpp.formatting` 为 `clang-format`
3. 可以设置保存时自动格式化:`editor.formatOnSave: true`

- **CLion**:
1. 在设置中选择 `Editor > Code Style > C/C++`
2. 将 `Formatter` 设置为 `clang-format`
3. 选择使用项目中的 `.clang-format` 配置文件

### 主要格式规则

- 缩进使用 4 个空格
- 行宽限制为 100 字符
- 大括号采用 Attach 风格(与控制语句在同一行)
- 指针和引用符号靠左对齐
- 自动排序头文件包含
- 类访问修饰符缩进为 -4 空格

### 注意事项

1. 提交代码前请确保代码已经过格式化
2. 不要手动调整已格式化的代码对齐
3. 如果某段代码不希望被格式化,可以使用以下注释包围:
```cpp
// clang-format off
// 你的代码
// clang-format on
```

### 常见问题

1. **格式化失败**:
- 检查 clang-format 版本是否过低
- 确认文件编码为 UTF-8
- 验证 .clang-format 文件语法是否正确

2. **与期望格式不符**:
- 检查是否使用了项目根目录下的 .clang-format 配置
- 确认没有其他位置的 .clang-format 文件被优先使用
