Overview

Package loglvl adds a bit of leveled logging to log.Logger.

Example

var buf bytes.Buffer
log := New(0, log.New(&buf, "", log.LstdFlags))

msg0 := "a level 0 message"
if log.Level() >= 0 {
	log.Println(msg0)
}

msg1 := "a level 1 message"
if log.Level() >= 1 {
	log.Println(msg1)
}

msgs := string(buf.Bytes())
fmt.Println(strings.Contains(msgs, msg0))
fmt.Println(strings.Contains(msgs, msg1))

Output:

true
false
