BLog4go Go高效日志库
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")
}
