Variables

var DefaultTokenizer = StringTokenizer(".")

DefaultTokenizer is a tokenizer using a dot or fullstop

Types

type Map

type Map struct {
	M map[string]interface{}
	// contains filtered or unexported fields
}

Map is a flatten map

func Flatten

func Flatten(m map[string]interface{}, tokenizer Tokenizer) (*Map, error)

Flatten takes a hierarchy and flatten it using the tokenizer supplied

func (*Map) Del

func (m *Map) Del(prefix string)

Del deletes a key out of the map with the given prefix

func (*Map) Expand

func (m *Map) Expand() map[string]interface{}

Expand expands the Map into a more complex structure. This is the reverse of the Flatten operation.

func (*Map) Move

func (m *Map) Move(original, newKey string)

Move makes changes in the flatten hierarchy moving contents from origin to newKey

type StringTokenizer

type StringTokenizer string

StringTokenizer is a Tokenizer using the string as separator

func (StringTokenizer) Keys

func (s StringTokenizer) Keys(ks string) []string

Keys returns the keys contained in the received token

func (StringTokenizer) Separator

func (s StringTokenizer) Separator() string

Separator returns the separator

func (StringTokenizer) Token

func (s StringTokenizer) Token(ks []string) string

Token returns a token joining all the keys with s as separator

type Tokenizer

type Tokenizer interface {
	Separator() string
	Token([]string) string
	Keys(string) []string
}

Tokenizer is an interface for key manipulators
