ruby - 是否有与 Java MessageFormat 等效的 Ruby？

Question

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}?

给定一个数组["sir", "Monday", "12:00", "tacos"]，这个字符串应该被格式化为：

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可以做到这一点？还是有宝石？还是我只需要更换字符串？

编辑：我想补充一点，我不允许编辑这些字符串。因此，类似 sprintf 的解决方案将不起作用。

Answer 1

使用内核#sprintf：

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

或者

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

Answer 2

 "Hello %s, today is %s and the time is %s. Will you be eating %s?" % ["sir", "Monday", "12:00", "tacos"]
# => "Hello sir, today is Monday and the time is 12:00. Will you be eating tacos?"

Answer 3

你可以这样做：

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" }

希望有帮助！

Answer 4

我做了一个，但由于 Ruby 不是我最擅长的，任何改进都将不胜感激。源代码在github 上。
