Logger in Go

A Logger represents an active logging object that generates lines of output to an io.Writer. Each logging operation makes a single call to the Writer's Write method. A Logger can be used simultaneously from multiple goroutines; it guarantees to serialize access to the Writer.

package main

import (
	"bytes"
	"fmt"
	"log"
)

func main() {
	var (
		buf    bytes.Buffer
		logger = log.New(&buf, "logger: ", log.Lshortfile)
	)

	logger.Print("Hello, log file!")

	fmt.Print(&buf)
}
