By using the Lazy wrapper, we can defer the evaluation of whether the player is alive or not to each log message, so that the log records will reflect the player's current state no matter when the log message is written: - p := &Player{name: name, alive: true} - isAlive := func() bool { return p.alive } - player.Logger = log.New("name", p.name, "alive", log.Lazy{isAlive}) + p := &Player{name: name, alive: true} + isAlive := func() bool { return p.alive } + player.Logger = log.New("name", p.name, "alive", log.Lazy{isAlive}) -Terminal Format +# Terminal Format If log15 detects that stdout is a terminal, it will configure the default handler for it (which is log.StdoutHandler) to use TerminalFormat.
