代码介绍

1. 核心功能

这是一个专为 macOS 设计的字体文件收集工具，能够：
✅ 智能扫描系统字体目录（如 /Library/Fonts）和用户指定目录
✅ 自动过滤 .ttf/.otf/.ttc 等字体文件
✅ 安全跳过无权限访问的目录（兼容 SIP 保护机制）
✅ 冲突处理自动重命名同名字体文件（追加 _1, _2 等后缀）
✅ 完整日志记录所有跳过的目录及原因

2. 技术亮点

🔧 现代 C++17 标准实现，跨平台兼容
🔧 使用库实现高效目录遍历
🔧 多线程安全的错误记录机制（std::mutex）
🔧 双重访问策略：
• 优先尝试直接递归访问

• 失败后自动降级为逐个子目录探测

3. 典型使用场景

📁 设计师工作流：快速收集散落在各处的商用字体
💻 开发者工具：为字体管理软件提供基础服务
🔐 系统维护：备份关键字体文件

4. 使用方法示例

FontCopier copier({“.ttf”, “.otf”}, “~/FontBackup”);
copier.add_custom_font_dir(“/”, true); // 全盘扫描（自动跳过系统保护区）
copier.run();

5. 输出

示例

=== macOS 字体拷贝工具 (C++17) ===
搜索字体类型: .ttf .otf
目标文件夹: /Users/Alice/FontBackup

正在尝试访问目录: /Library/Fonts
跳过受保护目录: /System/Library/Fonts (Operation not permitted)
找到 142 个字体文件:

正在拷贝: /Library/Fonts/Arial.ttf -> ~/FontBackup/Arial_1.ttf
…

操作完成。成功拷贝 138/142 个字体文件
跳过的目录 (3个):

/System/Library/Fonts (Operation not permitted)
/private/var/db (Permission denied)
扩展建议

🛠 可扩展为 GUI 工具（Qt/QML 前端）
🛠 添加网络字体下载功能
🛠 集成字体预览能力

注意：运行时可能需要 sudo 权限访问系统目录，但会严格遵守 macOS 权限系统限制
