Functions

func FromTreeToDictKey

func FromTreeToDictKey(k string) string

FromTreeToDictKey returns app name from tree key k: given tree key "foo{}:0:-62135596790", the call returns "foo".

Before tags support, segment key form (i.e. app name + tags: foo{key=value}) has been used to reference a dictionary (trie).

func FromTreeToMainKey

func FromTreeToMainKey(k string) string
