      • {fmt}就是Python花括号那套写法搬到C++来了。格式符写错编译直接给你报错,浮点数、时间、自己写的类型,都能直接塞进去打出来。 后来才反应过来,std::format本来就是从这库演化出来的。新标准我在项目里也用上了,但{fmt}一直没卸,毕竟用顺手了,迁移成本约等于零。 🔗

      • Most developers are still using printf or heavy iostreams in C++, wondering why their logging and string building bottlenecks performance. Then there is {fmt}. It is the ultra-fast, type-safe C++…

      • 还在让 printf 和 iostreams拖累性能、类型安全与可维护性,fmt值得直接纳入基础设施选型。 它支持编译期格式检查、Unicode、chrono、ranges和C++20模块,无外部依赖;浮点格式化采用Dragonbox,兼顾速度与正确舍入。新版本还提供类型安全的C11 API。适合日志、序列化和高吞吐输出,但升级时要留意头文件拆分及弃用接口。
