Installation

🔝 The minimum requirement of Go version is 1.11. 🔝 Your project also uses go module!!!

1. File Logger

package main

import (
	klog "github.com/higker/logker"
	"time"
)

func main() {
	// Specify file location! Create folder in advance!!
	dir := "/Users/ding/Documents/test_log"
	// New file logger
	// File Max size : You can also use built-in constants
	// klog.GB1  	= 1GB
	// klog.MB10  	= 10MB
 	// klog.MB100	= 100MB
	format := "{level} - DATE {time}  - POS {position} - MSG {message}" //This version was modified from v 1.1.5
	//Create Log Buffer
    	task := InitAsync(Qs1w)
   	flog,e := klog.NewFlog(klog.DEBUG, true, klog.Shanghai, dir, "log", 10*1024, 0777,format,task)
    	if e != nil{
       	    .... //Custom Operation
   	}
	// Analog output log
	for {
		flog.Debug("DEBUG : %d + %d = %d",1,2,1+2)
		flog.Error("ERROR")
		flog.Warning("WARNING %p",flog)
		flog.Info("INFO %s","Hello LogKer.")
		time.Sleep(2 * time.Second)
	}
}

	// TheCustomTagNameMustBe {level} {time} {position} {message}
	// The location of the custom label is the location

	// forExampleHereIsMyCustom
	// 1. //format := "{level} - {time} - {position} - {message}"

2. Console Logger

package main

import (
	"github.com/higker/logker"
	"strings"
)

//type Formatting string

// logKer library Test
func main() {
	// Now upgrade to version v 1.1.5 to customize the message output format ~
	// TheCustomTagNameMustBe {level} {time} {position} {message}
	// The location of the custom label is the location
	// where the program outputs the corresponding log message at run time！！！！
	// forExampleHereIsMyCustom
	// 1. //format := "{level} - {time} - {position} - {message}"
	format := "{level} - 时间 {time}  - 位置 {position} - 消息 {message}" //This version was modified from v 1.1.5
    	//Create Log Buffer
    	task := InitAsync(Qs1w)
	log,e := logker.NewClog(logker.DEBUG, logker.Shanghai, format,task)
    	if e != nil{
        	..... //Custom Operation
    	}
	log.Debug("DEBUG %s","自定义日志消息匹配符测试")
	log.Info("%v", log)
	log.Warning("%v", logker.Shanghai)
	log.Error("ERROR")
}
