Functions

func Expand

func Expand(input string, mapping func(string) interface{}) interface{}

Expand replaces variable references in the input string according to the expansion spec using the given mapping function to resolve the values of variables.

func MappingFuncFor

func MappingFuncFor(
	counts map[string]int,
	context ...map[string]interface{}) func(string) interface{}

MappingFuncFor returns a mapping function for use with Expand that implements the expansion semantics defined in the expansion spec; it returns the input string wrapped in the expansion syntax if no mapping for the input is found.
