Reference resources ：https://juejin.cn/post/6844904061393698823

Normal log settings

func InitLogger() {
    
    level := GetLogLevel(viper.GetString("LOG_LEVEL"))
    log.SetLevel(level)
    formatter := &log.TextFormatter{
    
        ForceColors:     true,// Set the color 
        FullTimestamp:   true,
        DisableQuote:    true,
        TimestampFormat: "2006-01-02 15:04:05",
    }
    log.SetFormatter(formatter)
    log.Debug("debug log level")
    log.Info("start")
}

Output of function name and file name

import (
    log "github.com/sirupsen/logrus"
)

func loggerInit() {
    
    // Initialize log 
    log.SetReportCaller(true) // You need to set this to true
    log.SetFormatter(&log.TextFormatter{
    
        TimestampFormat: "2006-01-02 15:03:04",
        ForceColors:     true,
        FullTimestamp:   true,
        DisableQuote:    true,
        CallerPrettyfier: func(frame *runtime.Frame) (function string, file string) {
    
            // Handle function name 
            fs := strings.Split(frame.Function, ".")
            fun := ""
            if len(fs) > 0 {
    
                fun = fs[len(fs)-1]
            }
            fileName := path.Base(frame.File)
            return fmt.Sprintf("[\033[1;34m%s\033[0m]", fun), fmt.Sprintf("[%s:%d]", fileName, frame.Line)
        },
    })
}

Third party log plugin

Install first

$ go get github.com/antonfisher/nested-logrus-formatter

Then call

package main

import (
    nested "github.com/antonfisher/nested-logrus-formatter"
    "github.com/sirupsen/logrus"
)


func main() {
    
    logrus.SetFormatter(&nested.Formatter{
    
        HideKeys:    true,
        TimestampFormat: "2006-01-02 15:04:05",
        FieldsOrder:     []string{
    "name", "age"},// You can configure the output order of fields 
    })

    logrus.Info("info msg")
}
