Import

import "github.com/typepress/log"

Usage

package main

import (
	"bytes"
	"fmt"
	"github.com/typepress/log"
)

func main() {
	w := bytes.NewBuffer(nil)
	m := log.Multi(
		log.New(
			w,        // io.Writer
			"prefix", // prefix string
			0,        // flag, 0 means none auto prefix.
		))

	l := log.New(w, "",
		log.LstdFlags|log.Lshortfile,
		log.Lmicroseconds,
	)

	m.Join(l)

	m.Info("info")
	m.Notify("Notify")

	l.Output(1, "Output")

	l.SetPrintLevel(log.LAlert)
	l.Print("SetPrintLevel: LAlert")

	l = log.New(w, "ModeEqualReport",
		0,
		log.MODE_EQUAL, // equal mode
		log.LReport,    // set level
	)

	m.Join(l)

	m.Error("Error")
	m.Report("Report")

	fmt.Println(w.String())
}

output:
