Documentation

Overview

Package log implements a small wrapper around the std lib log package. It implements log levels by prefixing the logs with [INFO], [DEBUG], [WARNING] or [ERROR]. Debug logging is available and enabled if the *debug* plugin is used.

log.Info("this is some logging"), will log on the Info level.

log.Debug("this is debug output"), will log in the Debug level, etc.

Variables

var D = &d{}

D controls whether we should output debug logs. If true, we do, once set it can not be unset.

Functions

func Debug

func Debug(v ...interface{})

Debug is equivalent to log.Print(), but prefixed with "[DEBUG] ". It only outputs something if D is true.

func Debugf

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

Debugf is equivalent to log.Printf(), but prefixed with "[DEBUG] ". It only outputs something if D is true.

func Discard

func Discard()

Discard sets the log output to /dev/null.

func Error

func Error(v ...interface{})

Error is equivalent to log.Print, but prefixed with "[ERROR] ".

func Errorf

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

Errorf is equivalent to log.Printf, but prefixed with "[ERROR] ".

func Fatal

func Fatal(v ...interface{})

Fatal is equivalent to log.Print, but prefixed with "[FATAL] ", and calling os.Exit(1).

func Fatalf

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

Fatalf is equivalent to log.Printf, but prefixed with "[FATAL] ", and calling os.Exit(1)

func Info

func Info(v ...interface{})

Info is equivalent to log.Print, but prefixed with "[INFO] ".

func Infof

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

Infof is equivalent to log.Printf, but prefixed with "[INFO] ".

func Warning

func Warning(v ...interface{})

Warning is equivalent to log.Print, but prefixed with "[WARNING] ".

func Warningf

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

Warningf is equivalent to log.Printf, but prefixed with "[WARNING] ".

Types

type P

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

P is a logger that includes the plugin doing the logging.

func NewWithPlugin

func NewWithPlugin(name string) P

NewWithPlugin returns a logger that includes "plugin/name: " in the log message. I.e [INFO] plugin/<name>: message.

func (P) Debug

func (p P) Debug(v ...interface{})

Debug logs as log.Debug.

func (P) Debugf

func (P) Error

func (p P) Error(v ...interface{})

Error logs as log.Error.

func (P) Errorf

func (p P) Errorf(format string, v ...interface{})

Errorf logs as log.Errorf.

func (P) Fatal

func (p P) Fatal(v ...interface{})

Fatal logs as log.Fatal and calls os.Exit(1).

func (P) Fatalf

func (p P) Fatalf(format string, v ...interface{})

Fatalf logs as log.Fatalf and calls os.Exit(1).

func (P) Info

func (p P) Info(v ...interface{})

Info logs as log.Info.

func (P) Infof

func (p P) Infof(format string, v ...interface{})
