Functions

func Errorf

func Errorf(format string, a ...interface{}) error

Errorf formats and returns error and logs at level 2

func Init

func Init(f *pflag.FlagSet, out io.Writer)

Init allows for the initialization of log via root command

func InitNoFlag

func InitNoFlag(out io.Writer, level Level)

InitNoFlag initializes without CLI flag which means the level must be initialized useful for tests

func Printf

func Printf(format string, args ...interface{})

Printf provides default level printing for things that will always print

Types

type Level

type Level int8

Level specifies a level of verbosity for V logs.

func (*Level) Get

func (l *Level) Get() interface{}

Get is required for https://godoc.org/flag#Getter the return of interface{} is forced by Getter interface

func (*Level) Set

func (l *Level) Set(value string) error

Set is part of the flag.Value interface.

func (*Level) String

func (l *Level) String() string

String is part of the flag.Value interface.

func (*Level) Type

func (l *Level) Type() string

Type is part of flag.Value interface

type Verbose

type Verbose bool

Verbose is boolean type that implements Println, Printf See glog and documentation for V

func V

func V(level Level) Verbose

V reports true if the verbosity at the call site is at least the request level. This the following glog style code samples are possible:

if clog.V(2) { clog.Print("log this") }

or

clog.V(2).Print("log this")

Whether the call site logs is determined by the `-v` flags.

func (Verbose) Printf

func (v Verbose) Printf(format string, args ...interface{})

Printf is equivalent to the global Printf function, guarded by the value of v. See the documentation of V for usage.
