使用“ logrus”包时如何消除日志之间的空间

Question

So I started using 'logrus'. I set it in my own logger package which looks like this:

    package logger

import(
     log "github.com/Sirupsen/logrus"

)


func InitLogger() {
    var textFormatter = new(log.TextFormatter)
    textFormatter.TimestampFormat = "2006-01-02 15:04:05"
    textFormatter.ForceColors = true
    textFormatter.FullTimestamp = true

    log.SetFormatter(textFormatter)
}


func Printf(format string, v ...interface{}) {
    log.Printf(format, v...)
}

func Fatalf(format string, v ...interface{}) {
    log.Fatalf(format, v...)
}

func Panicf(format string, v ...interface{}) {
    log.Panicf(format, v...)
}

func Debugf(format string, v ...interface{}) {
    log.Debugf(format, v...)

(it goes like this for all logrus log functions, dont see the point of pasting all of them here, but you get the idea...)

Use it across my project as:

import(
    log "logger"
)

And everything is peachy except logs being printed with line spaces between them:

INFO[2016-04-16 17:32:51] pathPrefix: /app/
pathValue: {js ./app/}

INFO[2016-04-16 17:32:51] pathPrefix: /node_modules/
pathValue: {js ./node_modules/}

INFO[2016-04-16 17:38:02] GET /auth AuthCheckHandler 82.195µs

How can I get rid of those spaces? Couldn't find any solution in documentation/google nor here so I assume its something very silly that I am missing...

Thanks

Seems like you are passing newlines when you pass your string formatting.

func main() {

  x := 0
  logger.InitLogger()

  logger.Printf("%s", "TEST1")
  logger.Printf("%s", "TEST2")

  if x == 0 {
      logger.Printf("%s", "TEST3")
      logger.Printf("%s", "TEST4")
      logger.Printf("%s", "TEST5")
  }
}

Returns:

go run main.go
INFO[2016-04-16 12:40:30] TEST1
INFO[2016-04-16 12:40:30] TEST2
INFO[2016-04-16 12:40:30] TEST3
INFO[2016-04-16 12:40:30] TEST4
INFO[2016-04-16 12:40:30] TEST5
