Variables

var ConfigDecodeHook = mapstructure.ComposeDecodeHookFunc(
	BoolToBoolValueFunc(),
	StringToDurationValueFunc(),
	StringToStringValueFunc(),
	Float64ToUintValueFunc(),
)

ConfigDecodeHook should be passed to mapstructure in order to decode into the *Value objects here.

Functions

func BoolToBoolValueFunc

func BoolToBoolValueFunc() mapstructure.DecodeHookFunc

BoolToBoolValueFunc is a mapstructure hook that looks for an incoming bool mapped to a BoolValue and does the translation.

func Float64ToUintValueFunc

func Float64ToUintValueFunc() mapstructure.DecodeHookFunc

Float64ToUintValueFunc is a mapstructure hook that looks for an incoming float64 mapped to a UintValue and does the translation.

func Merge

func Merge(dst, src *flag.FlagSet)

func StringToDurationValueFunc

func StringToDurationValueFunc() mapstructure.DecodeHookFunc

StringToDurationValueFunc is a mapstructure hook that looks for an incoming string mapped to a DurationValue and does the translation.

func StringToStringValueFunc

func StringToStringValueFunc() mapstructure.DecodeHookFunc

StringToStringValueFunc is a mapstructure hook that looks for an incoming string mapped to a StringValue and does the translation.

func Usage

func Usage(txt string, flags *flag.FlagSet) string

func Visit

func Visit(path string, visitor VisitFn) error

Visit will call the visitor function on the path if it's a file, or for each file in the path if it's a directory. Directories will not be recursed into, and files in the directory will be visited in alphabetical order.

Types

type AppendSliceValue

type AppendSliceValue []string

AppendSliceValue implements the flag.Value interface and allows multiple calls to the same variable to append a list.

func (*AppendSliceValue) Set

func (s *AppendSliceValue) Set(value string) error

func (*AppendSliceValue) String

func (s *AppendSliceValue) String() string

type BoolValue

type BoolValue struct {
	// contains filtered or unexported fields
}

BoolValue provides a flag value that's aware if it has been set.

func (*BoolValue) IsBoolFlag

func (b *BoolValue) IsBoolFlag() bool

IsBoolFlag is an optional method of the flag.Value interface which marks this value as boolean when the return value is true. See flag.Value for details.

func (*BoolValue) Merge

func (b *BoolValue) Merge(onto *bool)

Merge will overlay this value if it has been set.

func (*BoolValue) Set

func (b *BoolValue) Set(v string) error

Set implements the flag.Value interface.

func (*BoolValue) String

func (b *BoolValue) String() string

String implements the flag.Value interface.

type DurationValue

type DurationValue struct {
	// contains filtered or unexported fields
}

DurationValue provides a flag value that's aware if it has been set.

func (*DurationValue) Merge

func (d *DurationValue) Merge(onto *time.Duration)

Merge will overlay this value if it has been set.

func (*DurationValue) Set

func (d *DurationValue) Set(v string) error

Set implements the flag.Value interface.

func (*DurationValue) String

func (d *DurationValue) String() string

String implements the flag.Value interface.

type FlagMapValue

type FlagMapValue map[string]string

FlagMapValue is a flag implementation used to provide key=value semantics multiple times.
