Scala string template

Question

Is there default(in SDK) scala support for string templating? Example: "$firstName $lastName"(named not numbered parameters) or even constructs like for/if. If there is no such default engine, what is the best scala library to accomplish this.

Answer 1

If you want a templating engine, I suggest you have a look at scalate. If you just need string interpolation, "%s %s".format(firstName, lastName) is your friend.

Answer 2

Complementing Kim's answer, note that Java's Formatter accepts positional parameters. For example:

"%2$s %1$s".format(firstName, lastName)

Also, there's the Enhanced Strings plugin, which allows one to embed arbitrary expressions on Strings. For example:

@EnhanceStrings // enhance strings in this scope
trait Example1 {
  val x = 5
  val str = "Inner string arithmetics: #{{ x * x + 12 }}"
}
