详细描述

简化的文件系统操作类

本类提供了简化的文件系统操作接口，与c++17标准库filesystem的api规范保持一致。主要功能包括路径操作、文件属性查询、目录遍历等。

函数说明

◆ relative()

AST_UTIL_API path ast::fs_simple::relative	(	const path &	p,
		const path &	base,
		std::error_code &	ec )

noexcept

计算 p 相对于 base 的相对路径（对标 std::filesystem::relative）

注解: 若 p 和 base 根不同（如不同盘符）则设置 ec 并返回空路径
