Thanks To Uber ZapLog! Log to console or file very easy and fast!
Simple：
go get -v github.com/hunterhug/golog
default logger is InfoLevel, and has long func caller.
package main
import . "github.com/hunterhug/golog"
func main() {
// use default log
Info("now is Info", 2, " good")
Debug("now is Debug", 2, " good")
Warn("now is Warn", 2, " good")
Error("now is Error", 2, " good")
Infof("now is Infof: %d,%s", 2, "good")
Debugf("now is Debugf: %d,%s", 2, "good")
Warnf("now is Warnf: %d,%s", 2, "good")
Errorf("now is Errorf: %d,%s", 2, "good")
Sync()
// config log
SetLevel(DebugLevel).SetCallerShort(true).SetOutputJson(true).InitLogger()
Info("now is Info", 2, " good")
Debug("now is Debug", 2, " good")
Warn("now is Warn", 2, " good")
Error("now is Error", 2, " good")
Infof("now is Infof: %d,%s", 2, "good")
Debugf("now is Debugf: %d,%s", 2, "good")
Warnf("now is Warnf: %d,%s", 2, "good")
Errorf("now is Errorf: %d,%s", 2, "good")
Sync()
}Output:

you can config log to file and auto rotate.

AddFieldFunc(func(ctx context.Context, m map[string]interface{}) {
m["diy_filed"] = ctx.Value("diy")
})
SetOutputFile("./log", "demo").SetFileRotate(30*24*time.Hour, 24*time.Hour)
SetIsOutputStdout(true)
InitLogger()

InfoWithFields(map[string]interface{}{"k1": "sss"}, "InfoWithFields")
err := Sync()
if err != nil {
fmt.Println(err.Error())
}
}Output is in the file dir ·/log, due to SetIsOutputStdout is true it also output to console.
very easy to understand.
