const RotatorMaxFiles = 1024

Functions

func CmdLineFlags

func CmdLineFlags(flags *flag.FlagSet)

Adds logging specific flags to the flag set. The taken flags are -v, -e and -d.

func Critical

func Critical(format string, v ...interface{})

func Debug

func Debug(selector string, format string, v ...interface{})

func Err

func Err(format string, v ...interface{})

func Info

func Info(format string, v ...interface{})

func Init

func Init(name string, config *Logging) error

Init combines the configuration from config with the command line flags to initialize the Logging systems. After calling this function, standard output is always enabled. You can make it respect the command line flag with a later SetStderr call.

func IsDebug

func IsDebug(selector string) bool

func LogInit

func LogInit(level Priority, prefix string, toSyslog bool, toStderr bool, debugSelectors []string)

TODO: remove toSyslog and toStderr from the init function

func Recover

func Recover(msg string)

func SetStderr

func SetStderr()

func SetToFile

func SetToFile(toFile bool, rotator *FileRotator) error

func SetToStderr

func SetToStderr(toStderr bool, prefix string)

func SetToSyslog

func SetToSyslog(toSyslog bool, prefix string)

func WTF

func WTF(format string, v ...interface{})

WTF prints the message at CRIT level and panics immediately with the same message

func Warn

func Warn(format string, v ...interface{})
