Constants

const (
	LogNone = iota
	LogError

func LogLevel

func LogLevel() (i int)

LogLevel reads the log level from the EnvLogLevel environment variable and defaults to the info level if it is not set.

func Mustenv

func Mustenv(names ...string)

Mustenv ensures an environment variable is set and panics if it is not.

func QueueURL

func QueueURL() string

QueueURL returns the SQS Queue URL set in the environment variable.

func SendMessage

func SendMessage(svc sqsiface.SQSAPI, input *sqs.SendMessageInput) (output *sqs.SendMessageOutput)

SendMessage sends a message to SQS and panics on any errors.

Types

type LeveledLogger

type LeveledLogger struct {
	ErrorLogger  *log.Logger
	NoticeLogger *log.Logger
	InfoLogger   *log.Logger
	DebugLogger  *log.Logger
}

func NewLogger

func NewLogger(level int) *LeveledLogger

NewLogger returns a LeveledLogger that writs logs to os.Stdout or ioutil.Discard depending on the passed minimum log level.

func (LeveledLogger) Debug

func (l LeveledLogger) Debug(format string, v ...interface{})

Debug writes a debug level log.

func (LeveledLogger) Error

func (l LeveledLogger) Error(format string, v ...interface{})

Error writes an error level log.

func (LeveledLogger) Info

func (l LeveledLogger) Info(format string, v ...interface{})

Info writes an info level log

func (LeveledLogger) Notice

func (l LeveledLogger) Notice(format string, v ...interface{})

Notice writes an notice level log.

func (*LeveledLogger) Panic

func (l *LeveledLogger) Panic(format string, v ...interface{})

Panic writes an error level log and panics.
