BLog4go 是高性能日志库。创新地使用“边解析边输出”方法进行日志输出,同时支持回调函数、日志淘汰和配置文件。可以解决高并发,调用日志函数频繁的情境下,日志库造成的性能问题。
快速启动:
package main import ( log "github.com/YoungPioneers/blog4go" "fmt" "os" ) // optionally set user defined hook for logging type MyHook struct { something string } // when log-level exceed level, call the hook // level is the level associate with that logging action. // message is the formatted string already written. func (self *MyHook) Fire(level log.Level, message string) { fmt.Println(message) } func main() { // init a file write using xml config file err := log.NewFileWriterFromConfigAsFile("config.xml") if nil != err { fmt.Println(err.Error()) os.Exit(1) } defer log.Close() // initialize your hook instance hook := new(MyHook) log.SetHook(hook) // writersFromConfig can be replaced with writers log.SetHookLevel(log.INFO) log.SetHookAsync(true) // hook will be called in async mode // optionally set output colored log.SetColored(true) log.Debugf("Good morning, %s", "eddie") log.Warn("It's time to have breakfast") }
