F_ASYNC      = 1 << iota // 开启日志异步输出
F_FILE_LONG              // 打印调用行号信息，完整绝对路径，例如：/a/b/c/d.go:23
F_FILE_SHORT             // 打印调用行号信息，仅打印文件名，例如：d.go:23，覆盖 F_FILE_LONG.
F_TIME_DATE              // 打印当前日期，如：2009-01-23
F_TIME_TIME              // 打印当前时间，如：01:23:23
F_TIME_MILLI             // 打印当前时间+毫秒，如：01:23:23.675
F_TIME_STD = F_TIME_DATE | F_TIME_MILLI // (默认)打印当前日期+时间+毫秒，如：2009-01-23 01:23:23.675

使用示例：

package main

import (
	"context"

	"github.com/gogf/gf/v2/os/glog"
)

func main() {
	ctx := context.TODO()
	l := glog.New()
	l.SetFlags(glog.F_TIME_TIME | glog.F_FILE_SHORT)
	l.

...

Print(ctx, "time and short line number")
	l.SetFlags(glog.F_TIME_MILLI | glog.F_FILE_LONG)
	l.

...

Print(ctx, "time with millisecond and long line number")
	l.SetFlags(glog.F_TIME_STD | glog.F_FILE_LONG)
	l.

...

Print(ctx, "standard time format and long line number")
}

执行后，终端输出结果为：
