Overview

Package log provides logging utility.

It abstracts the logger from the standard log package, allowing the developer to patck the logging target, changing this to a file, or syslog, for example.

Types

type Target

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

Target is the current target for the log package.

func (*Target) Fatal

func (t *Target) Fatal(v ...interface{})

Fatal is equivalent to Print() followed by os.Exit(1).

func (*Target) Fatalf

func (t *Target) Fatalf(format string, v ...interface{})

Fatalf is equivalent to Printf followed by os.Exit(1).

func (*Target) Panic

func (t *Target) Panic(v ...interface{})

Panic is equivalent to Print() followed by panic().

func (*Target) Panicf

func (t *Target) Panicf(format string, v ...interface{})

func (*Target) Print

func (t *Target) Print(v ...interface{})

Print is similar to fmt.Print, writing the given values to the Target logger.

func (*Target) Printf

func (t *Target) Printf(format string, v ...interface{})

Printf is similar to fmt.Printf, writing the formatted string to the Target logger.

func (*Target) SetLogger

func (t *Target) SetLogger(l *log.Logger)

SetLogger defines a new logger for the current target.

See the builtin log package for more details.
