Types

type Logger

type Logger interface {
	Is(level int) bool
	V(level int) Logger
	Infof(format string, args ...interface{})
}

Logger is a simple interface that is roughly equivalent to glog.

var (
	// None implements the Logger interface but does nothing with the log output
	None Logger = discard{}
	// Log implements the Logger interface for Glog
	Log Logger = glogger{}
)

func ToFile

func ToFile(w io.Writer, level int) Logger

ToFile creates a logger that will log any items at level or below to file, and defer any other output to glog (no matter what the level is.)
