golog

golog

A new log package for go

There are several handlers :

• StreamHandler : write log to io.Writer interface
• SocketHandler : write log to socket
• RotatingFileHandler : write log to file which rotating as size
• TimeRotatingFileHandler : write log to file which rotating as time(second, minute, hour, day)
• SentryHandler : write log to sentry(Sentry is a modern error logging and aggregation platform.)

coding

    // clear all handlers already exist
	ClearHandlers()
	
	// new a stream handler : write log to stdout
	h,_ := NewStreamHandler(os.Stdout)
	// append the handler to golog
	AppendHandler(h)
	
	// new a socket handler : it is tcp protocol, address is localhost:8989 and timeout is second
	h2,_ := NewSocketHandler("tcp", "localhost:8989", time.Second)
	AppendHandler(h2)
	
	// new a sentry handler : write log to sentry 
	c, err := raven.NewClient("xxx", nil)
	if err != nil {
		t.Error("raven.NewClient fail:" + err.Error())
	}
	h3, _ := NewSentryHandler(c)
	AppendHandler(h3)
	
	// write log to fileName
	// size of rotating is 10 bytes
	// count is 2 : max count of rotating
	h4, _ := NewSizeRotateFileHandler(fileName, 10, 2)
	AppendHandler(h4)
	
	// the log will be written to h1, h2, h3, h4
	
	Warnf("%v\n", "Warnf")
	Warnln("Warnf")
	Warnf("%v\n", "Warnf")
	Debugf("%v\n", "Debugf")
	Tracef("%v\n", "Tracef")
	Fatalf("%v\n", "Fatalf")
	
	Close()

level

//value:
LevelTrace 
LevelDebug
LevelInfo
LevelWarn
LevelError
LevelFatal

This is severity of log If you set level is LevelWarn LevelWarn, LevelError, LevelFatal are available LevelTrace, LevelDebug, LevelInfo will be ignore

you can set level like this:

golog.SetLevel(golog.LevelWarn)

flag

log header format:

//value
Ltime  	// 2006/01/02 15:04:05
Lfile	// file.go[123]
Llevel	// [Trace]

you can set flag like this:

golog.SetFlag(golog.Ltime | golog.Lfile)
