How to check whether a String fully matches a Regex in Scala?

Answering my own question I’ll use the “pimp my library pattern”

object RegexUtils {
  implicit class RichRegex(val underlying: Regex) extends AnyVal {
    def matches(s: String) = underlying.pattern.matcher(s).matches
  }
}

and use it like this

import RegexUtils._
val Digit = """\d""".r
if (Digit matches "5") println("match")
else println("no match")

unless someone comes up with a better (standard) solution.

Notes

• I didn’t pimp String to limit the scope of potential side effects.

• unapplySeq does not read very well in that context.
