Types

type Formatter 

type Formatter interface {
	Format(pkg string, level LogLevel, depth int, entries ...interface{})
	Flush()
}

func NewDefaultFormatter

func NewJournaldFormatter 

func NewJournaldFormatter() (Formatter, error)

func NewLogFormatter 

func NewLogFormatter(w io.Writer, prefix string, flag int) Formatter

NewLogFormatter is a helper to produce a new LogFormatter struct. It uses the golang log package to actually do the logging work so that logs look similar.

func NewNilFormatter 

func NewNilFormatter() Formatter

NewNilFormatter is a helper to produce a new LogFormatter struct. It logs no messages so that you can cause part of your logging to be silent.

func NewPrettyFormatter 

func NewPrettyFormatter(w io.Writer, debug bool) Formatter

func NewStringFormatter 

func NewStringFormatter(w io.Writer) Formatter

func NewSyslogFormatter 

func NewSyslogFormatter(w *syslog.Writer) Formatter

type GlogFormatter 

type GlogFormatter struct {
	StringFormatter
}

type LogFormatter 

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

LogFormatter emulates the form of the traditional built-in logger.

func (*LogFormatter) Flush 

func (lf *LogFormatter) Flush()

func (*LogFormatter) Format 

func (lf *LogFormatter) Format(pkg string, _ LogLevel, _ int, entries ...interface{})

Format builds a log message for the LogFormatter. The LogLevel is ignored.

type LogLevel 

type LogLevel int8

LogLevel is the set of all log levels. 

const (
	// CRITICAL is the lowest log level; only errors which will end the program will be propagated.
	CRITICAL LogLevel = iota - 1
	// ERROR is for errors that are not fatal but lead to troubling behavior.
	ERROR
	// WARNING is for errors which are not fatal and not errors, but are unusual. Often sourced from misconfigurations.
	WARNING
	// NOTICE is for normal but significant conditions.
	NOTICE
	// INFO is a log level for common, everyday log updates.
	INFO
	// DEBUG is the default hidden level for more verbose updates about internal processes.
	DEBUG
	// TRACE is for (potentially) call by call tracing of programs.
	TRACE
)

type NilFormatter 

type NilFormatter struct {
}

NilFormatter is a no-op log formatter that does nothing.

func (*NilFormatter) Flush 

func (_ *NilFormatter) Flush()
