2. Overview

common_util is a general-purpose C++ utility library, include the following functions:

  • Time utilities
  • Function timer
  • Filepath utilities
  • Filesystem utilities
  • String utilities
  • Data formatting
  • Singleton pattern macro definition

common_util is implemented in modern C++ syntax (C++11 and above), using cutl as the namespace. The naming convention of all interfaces is consistent with the STL, and it can be used as an extensions of C++ standard library. You can use common_util just like using the STL, For example:

++
// Data formatting
std::cout << "fmt_uint: " << cutl::fmt_uint(12, 5) << std::endl;
std::cout << "fmt_double: " << cutl::fmt_double(3.141592653, 4) << std::endl;
std::cout << "fmt_filesize: " << cutl::fmt_filesize(33600) << std::endl;
// Get the current system time
auto now = cutl::datetime::now();
std::cout << "current time(UTC time): " << now.utctime() << std::endl;
std::cout << "current time(local time): " << now.format() << std::endl;
cutl::datetime::now
static datetime now()
Get a datetime object for the current system time.

3. Library Features

  • Simple and lightweigh: Based on basic C++ syntax and STL, it independent on any third-party libraries.
  • Multi-platform support: Supports multiple platforms such as Linux/macOS/Windows, it can be compiled and run on multiple platforms.
  • Clean code: The code style is clean, and the naming convention is consistent with the STL, you can use this library just like use the C++ standard library.
  • Comprehensive documentation: All exported header files have detail comments, it has complete API reference and usage demos.
  • C++ version requirement: C++11 and above versions.

8. 概述

common_util是C++的一个通用工具库，主要包含以下功能：

  • 时间处理
  • 函数计时器
  • 路径处理
  • 文件操作
  • 字符串处理
  • 数据格式化
  • 单例模式宏定义

common_util采用现代C++语法（C++11及以上）实现，使用cutl作为命名空间，所有接口的命名方式与STL保持一致，可以作为STL库的一个补充。你可以像使用STL一样使用common_util，如：

++
// 数据格式化
std::cout << "fmt_uint: " << cutl::fmt_uint(12, 5) << std::endl;
std::cout << "fmt_double: " << cutl::fmt_double(3.141592653, 4) << std::endl;
std::cout << "fmt_filesize: " << cutl::fmt_filesize(33600) << std::endl;
// 获取系统当前时间
auto now = cutl::datetime::now();
std::cout << "current time(UTC time): " << now.utctime() << std::endl;
std::cout << "current time(local time): " << now.format() << std::endl;

9. 设计特点

  • **轻量极简**： 基于基础C++语法和STL，不依赖任何第三方库。
  • **多平台支持**： 支持Linux/OS-X/Windows等多个平台，一套代码多平台编译。
  • **代码整洁**： 代码风格整洁，命名方式与STL保持一致，你可以像使用STL一样使用本库。
  • **文档规范全面**： 所有对外接口的头文件都有详细的代码注释，且有完整的API文档和使用Demo，可供查阅。
  • **C++版本要求**： C++11及以上版本。
