Golang logging

Logging is a standardized format of writing progress/debug info.

Example

// ./logger.go

package main

import "os"
import "log"

// params:
//   1. device you'd like to log to
//   2. log-prefix of this logger
//   3. log-formatting options
//
var Logger = log.New(os.Stderr, "", log.Ldate|log.Ltime|log.Lshortfile)

// ./main.go

package main

func main() {
    Logger.Println("this is a test")
}

go run main.go logger.go  # build/run
