README ¶

简介

作者：京城郭少

关于项目

依赖logrus和file-rotatelogs

特点

每个level都会独立输出到不同的文件。
支持日志切割。
支持输出文件名、函数名和行号。
非DEBUG模式不输出到终端。

Question

问：为什么要自己实现一个输出行号的Hook？

答：logrus作者也不建议输出行号，这会降低程序的性能，这也是logrus迟迟不增加这项功能的原因。而glog的Hook在INFO这个level上是不打日志的，所以性能的损耗一般可以忽略。

版本日志

Version 1.2.0

支持通过配置文件创建Logger，进而自定义是否输出Caller等信息。

Version 1.3.0

支持Windows。rotatelogs这个库对Win10老版本、win10以前的版本、go1.11以下下版本支持得很不好，会出现无法创建软连接的问题。这个版本通过不创建软链接来解决。
