Method GetAndPrintObjectsWithFallback

utils/printer.go:171–209

GetAndPrintObjectsWithFallback retrieves objects from the specified endpoints and prints them. The function tries the endpoints in the order they are provided until one of them returns the object. The endpoint must contain a %s placeholder that will be replaced with items from the args slice. If arg

(endpoints []string, r StringReader, argRe *regexp.Regexp)

// "-" string, the args are read from stdin one per line. If argRe is non-nil, only
// args that match the regular expression are used and the rest are discarded.

	for s, err := r.ReadString(); s != "" || err == nil; s, err = r.ReadString() {
