SprintfDict formats a string according to a pattern and a dictionary of variables. The pattern is a string that contains placeholders for the variables in the form of ${key}. The dict is a map from keys to values that will replace the placeholders. For example, SprintfDict(“Hello, ${name}!”, map[string]string{“name”: “Alice”}) returns “Hello, Alice!”. If the pattern contains a key that is not in the dict, it will be left unchanged. If the dict contains a key that is not in the pattern, it will be ignored.
