Functions

func AddLoggingHandler

func AddLoggingHandler(next http.Handler) http.Handler

AddLoggingHandler will decorate the passed handler with a wrapper which will emit log messages whenever a request is received, in addition to calling the original handler.

func Debug

func Debug(a ...interface{})

Debug prints a message to the log if debug mode is enabled, it accepts arguments similar to log.Println.

func GetLogger

func GetLogger() *log.Logger

GetLogger returns the active logging object for creating new messages.

func SetLoggerFile

func SetLoggerFile(filename string) (err error)

SetLoggerFile changes the logging destination to a file. If a logger is already active, or the file cannot be opened, then the stderr logger will be used and an error will be returned.
