我有一个格式的字符串：
Hello {0}, today is {1} and the time is {2}. Will you be eating {3}?
给定数组["sir", "Monday", "12:00", "tacos"]，此字符串应格式化为：
Hello sir, today is Monday and the time is 12:00. Will you be eating tacos?
Ruby是否有某种内置方法来执行此操作？还是有宝石？或者我必须只更换字符串？
编辑：我想补充一点，我不允许编辑这些字符串。因此，类似sprintf的解决方案不起作用。

sprintf("Hello %s, today is %s and the time is %s. Will you be eating %s?", *["sir", "Monday", "12:00", "tacos"])
或
"Hello %s, today is %s and the time is %s. Will you be eating %s?" % ["sir", "Monday", "12:00", "tacos"]

您可以这样做：
message = "Hello %{tile}, today is %{day_name} and the time is %{time}. Will you be eating %{food}?"
p message % { title: "sir", day_name: "Monday", time: "12:00", food: "tacos" }
