Go语言可输出按分隔符分割格式（如CSV）日志并按时间切分的日志模块bizlogger

bizlogger是一款可输出CSV日志并按时间切分的日志模块，分割符可定制。goroutine安全。日志字符串拼接采用先计算总长度再一次性分配内存的方法来提升效率。按时间切分功能利用的是logrotator来实现的。

用法：

package main

import (
	"fmt"
	"github.com/pochard/bizlogger"
	"time"
)

func main() {
	// rollup every 20 minutes. And the log line is separated by ","
	logger, err := bizlogger.NewTabLogger("/data/web_log/click1-%Y%m%d-%H%M.log", 20*time.Minute, ",")
	if err != nil {
		fmt.Printf("%v", err)
		return
	}
	defer logger.Close()

	sl := make([]string, 4)
	sl[0] = "410001"
	sl[1] = "1583893679"
	sl[2] = "183.199.195.151"
	sl[3] = "C03FD5AAB4CA"

	for i := 0; i != 10; i++ {
		err := logger.Log(sl)
		if err != nil {
			fmt.Printf("%v", err)
		}
	}
}

输出日志：

click1-20200328-0920.log
click1-20200328-0940.log
click1-20200328-1000.log
