Yalogi
Yalogi means "Yet Another Logger Interface" and provides a simple logger interface for use it in my golang projects.
Usage
It offers a log interface for unstructured and leveled log system. It can be used with some popular log libraries like logrus or zap.
func main() {
//instantiate the logrus logger
logger := logrus.New()
logger.SetLevel(logrus.DebugLevel)
//we can use logrus because satisfaces the interface yalogi
withYalogi(logger)
//we can convert to a standar log
standarlog := yalogi.NewStandard(logger, yalogi.Info)
standarlog.Printf("mensaje a un log estandar %v informativo\n", 1234)
fmt.Println("fin de programa")
}
func withYalogi(logger yalogi.Logger) {
logger.Debugf("esto es debug")
logger.Infof("esto es informativo")
logger.Warnf("esto es una advertencia")
}
Also it includes a null implementation yalogi.LogNull for no logging that can be used as a default log for a component.

Types ¶
type Logger ¶
type Logger interface {
Debugf(template string, args ...interface{})
Infof(template string, args ...interface{})
Warnf(template string, args ...interface{})
Errorf(template string, args ...interface{})
Fatalf(template string, args ...interface{})
}
Logger is the main interface of the package
Example ¶
package main
import (
"os"
"github.com/luisguillenc/yalogi"
"github.com/sirupsen/logrus"
)
func main() {
withYalogi := func(logger yalogi.Logger) {
logger.Debugf("esto es debug")
logger.Infof("esto es informativo")
logger.Warnf("esto es una advertencia")
}
//instantiate the logrus logger
logger := logrus.New()
formatter := &logrus.TextFormatter{
DisableColors: true,
DisableTimestamp: true,
}
logger.SetFormatter(formatter)
logger.SetLevel(logrus.DebugLevel)
logger.SetOutput(os.Stdout)
//we can use logrus in func because satisfaces the interface yalogi
withYalogi(logger)
//we can convert a yalogi to a standar log
standarlog := yalogi.NewStandard(logger, yalogi.Info)
standarlog.Printf("mensaje a un log estandar %v informativo\n", 1234)
}
Output: level=debug msg="esto es debug" level=info msg="esto es informativo" level=warning msg="esto es una advertencia" level=info msg="mensaje a un log estandar 1234 informativo\n"
