Import

import "github.com/typepress/log"

Usage

package main
import (
"bytes""fmt""github.com/typepress/log"
)
funcmain() {
w:=bytes.NewBuffer(nil)
m:=log.Multi(
log.New(
w, // io.Writer"prefix", // prefix string0, // 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 modelog.LReport, // set level
)
m.Join(l)
m.Error("Error")
m.Report("Report")
fmt.Println(w.String())
}

output:

prefix [I] "info"
[I] 2014-02-18 17:30:27.154305 <hello.go:25> "info"
