Functions

func LoggerTypeToString

func LoggerTypeToString(t LoggerType) string

Types

type LogLevel

type LogLevel uint

LogLevel controls what log statements are activated for a given logger

const (
	FATAL LogLevel = iota
	ERROR
	WARN
	INFO
	DEBUG
	TRACE
)

Log levels

func LogLevelFromString

func LogLevelFromString(name string) LogLevel

func (LogLevel) String

func (ll LogLevel) String() string

String returns the canonical name of the level

type Logger

type Logger struct {
	ExitOnFatal bool
	// contains filtered or unexported fields
}

Logger maintains a set of logging functions and has a log level that can be modified dynamically

func NewLogger

func NewLogger(out io.Writer, cs *iostreams.ColorScheme) *Logger

NewLogger creates a new logger Default level is INFO

func (*Logger) Clone
