Overview

Package log provides simple convenience wrappers for logging.

Following convention, this provides functions for logging warnings, errors, information and debugging.

Index

• Variables
• func Debug(msg string, v ...interface{})
• func Err(msg string, v ...interface{})
• func Info(msg string, v ...interface{})
• func Warn(msg string, v ...interface{})
• type Receiver

Variables

var IsDebugging = false

IsDebugging controls debugging output.

If this is true, debugging messages will be printed. Expensive debugging operations can be wrapped in `if log.IsDebugging {}`.

Functions

func Debug

func Debug(msg string, v ...interface{})

Debug prints an error severity DEBUG to the log.

Debug will only print if IsDebugging is true.

func Err

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

Err prints an error of severity ERROR to the log.

func Info

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

Info prints an error of severity INFO to the log.

func Warn

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

Warn prints an error severity WARN to the log.

Types

type Receiver

type Receiver interface {
	Printf(format string, v ...interface{})
}

Receiver can receive log messages from this package.

var Logger Receiver = log.New(os.Stderr, "", log.LstdFlags)

Logger is the destination for this package.

The logger that this prints to.
