Types

type Fields

type Fields map[string]interface{}

type Logger

type Logger struct {
	// contains filtered or unexported fields
}

Logger is user-immutable immutable struct which can log to several outputs

func New

func New(prefix string, verbose bool, sinks ...Sink) *Logger

New creates a new Logger which logs to all the supplied sinks. The prefix argument is passed to all loggers under the field "prefix" with every log message. If verbose is true, more expensive runtime fields will be computed and passed to loggers. These fields are funcname, lineno, pathname, and filename.

func NewSimple

func NewSimple(sinks ...Sink) *Logger

NewSimple(sinks...) is equivalent to New("", false, sinks...)

func (*Logger) AddSink

func (logger *Logger) AddSink(s Sink)

Appends a new Sink to the Loggers slice of Sinks.

func (*Logger) Alert

func (logger *Logger) Alert(v ...interface{})

func (*Logger) Alertf

func (logger *Logger) Alertf(format string, v ...interface{})

func (*Logger) Critical

func (logger *Logger) Critical(v ...interface{})

func (*Logger) Criticalf

func (logger *Logger) Criticalf(format string, v ...interface{})

func (*Logger) Debug

func (logger *Logger) Debug(v ...interface{})

func (*Logger) Debugf

func (logger *Logger) Debugf(format string, v ...interface{})

func (*Logger) Emergency

func (logger *Logger) Emergency(v ...interface{})

func (*Logger) Emergencyf

func (logger *Logger) Emergencyf(format string, v ...interface{})

func (*Logger) Error

func (logger *Logger) Error(v ...interface{})

func (*Logger) Errorf

func (logger *Logger) Errorf(format string, v ...interface{})

func (*Logger) Fatalf

func (logger *Logger) Fatalf(format string, v ...interface{})

func (*Logger) Fatalln

func (logger *Logger) Fatalln(v ...interface{})

func (*Logger) Info

func (logger *Logger) Info(v ...interface{})

func (*Logger) Infof

func (logger *Logger) Infof(format string, v ...interface{})

func (*Logger) Log

func (logger *Logger) Log(priority Priority, v ...interface{})

This function has an unusual name to aid in finding it while walking the stack. We need to do some dead reckoning from this function to access the caller's stack, so there is a consistent call depth above this function.

func (*Logger) Logf

func (logger *Logger) Logf(priority Priority, format string, v ...interface{})

func (*Logger) Notice

func (logger *Logger) Notice(v ...interface{})

func (*Logger) Noticef

func (logger *Logger) Noticef(format string, v ...interface{})

func (*Logger) Panicf

func (logger *Logger) Panicf(format string, v ...interface{})

func (*Logger) Panicln

func (logger *Logger) Panicln(v ...interface{})

func (*Logger) Printf

func (logger *Logger) Printf(format string, v ...interface{})

func (*Logger) Println

func (logger *Logger) Println(v ...interface{})

func (*Logger) Warning

func (logger *Logger) Warning(v ...interface{})

func (*Logger) Warningf

func (logger *Logger) Warningf(format string, v ...interface{})

type Priority

type Priority int
const (
	PriEmerg Priority = iota
	PriAlert
	PriCrit
	PriErr
	PriWarning
	PriNotice
	PriInfo
	PriDebug
)

func (Priority) String

	Log(Fields)
}
