func Sprintt

func Sprintt(format string, params map[string]interface{}) string

Sprintt is like fmt.Sprintf, but accepts named parameters from a map.

Example:

params := map[string]interface{}{
  "hello": "world",
  "num":   42,
}

result := internal.Sprintt("Hello %{hello}s. The answer is %{num}d", params)

Result will then be: 'Hello world. The answer is 42'
