问题描述

val name = "mike"
val str = """Hi, {name}!"""
println(str)

我希望它输出 str 为 Hi，mike！，但失败了.如何做到这一点?

I want it output the str as Hi, mike!, but failed. How to do this?

推荐答案

Scala 不支持字符串插值.有一个编译器插件可以在 http://github.com/jrudolph/scala-enhanced-字符串.

Scala does not support string interpolation. There is a compiler plugin that implements it at http://github.com/jrudolph/scala-enhanced-strings.

如果没有插件，您可以使用连接或格式字符串:

Without the plugin you can use concatenation or format strings:

val str = name formatted "Hi, %s!"

或者当然

val str = "Hi, %s!".format(name)
