Types ¶

type Logger ¶

type Logger struct {
	*log.Logger
	// contains filtered or unexported fields
}

Logger is an extended version of the golang Logger to support structured errors.

func New ¶

func New(out io.Writer, prefix string, debug bool) *Logger

New creates a new Logger with no Log flags set.

func NewLogSet ¶

func NewLogSet(prefix string, debug bool) (stderr, diagnostic, stdout *Logger)

NewLogSet returns a set of Loggers for commonly used output streams: errors, diagnostics, stdout. The error and stdout streams should generally never be suppressed. diagnostic can be suppressed by setting the output to ioutil.Discard. If an output destination is not needed, one can simply discard it by assigning it to '_'.

func (*Logger) Error ¶

func (l *Logger) Error(e error)

Error is a convenience function for printing errors without a message.

func (*Logger) Errorf ¶ added in v1.20.0

func (l *Logger) Errorf(format string, a ...interface{})

Errorf is a convenience function for formatting and printing errors.

func (*Logger) FatalE ¶

func (l *Logger) FatalE(msg string, e error)

FatalE prints a string and error then calls os.Exit(254).

func (*Logger) Fatalf ¶ added in v1.20.0

func (l *Logger) Fatalf(format string, a ...interface{})

Fatalf prints an error then calls os.Exit(254).

func (*Logger) PanicE ¶

func (l *Logger) PanicE(msg string, e error)

PanicE prints a string and error then calls panic.

func (*Logger) PrintE ¶

func (l *Logger) PrintE(msg string, e error)

PrintE prints the msg and its error message(s).

func (*Logger) SetDebug ¶

func (l *Logger) SetDebug(b bool)

SetDebug sets the debug flag to the value of b

func (*Logger) SetFlags ¶

func (l *Logger) SetFlags(flag int)
