func ExtractValuesFromArgumentList ¶

func ExtractValuesFromArgumentList(key string, argumentList []string) (values string, err error)

ExtractValuesFromArgumentList extracts the argument value from an argument list. When the argument is found, ok is true and the value is returned. When the argument is found but no value is provided, ok is true and an empty string is returned. When the argument is not found, ok is false and the value is an empty string.

func ExtractValuesFromNestedMaps ¶

func ExtractValuesFromNestedMaps(m map[string]interface{}, keys ...string) (val interface{}, err error)

ExtractValuesFromNestedMaps takes a map and a list of keys and visits a tree of nested maps using the keys in the order provided. At each iteration, if the number of non-visited keys is 1, the function returns the value associated to the last key, else if it is greater than 1, the function expects the value to be a map and a new recursive iteration happens. In case the key is not found, an empty string is returned. In case no keys are provided, an error is returned. Example:

m := map[string]interface{}{
	"first": map[string]interface{}{
		"second": map[string]interface{}{
			"third": "value",
		},
	},
}
ValueFor(m, "first", "second", "third") // returns "value", nil
ValueFor(m, "first", "second") // returns map[string]interface{}{ "third": "value" }, nil
ValueFor(m, "first", "third") // returns "", nil
ValueFor(m) // returns nil, "At least one key is required"
