Scala：带字符串插值的正则表达式匹配

Question

I have two regex that I want to merge in one final regex to match text against this. Is there a way to get it with string interpolation or the right way is different?

val regex1 = "....".r
val regex2 = "....".r

val finalRegex = "^($regex1)(?:($regex2))$".r

is that possible?

Answer 1

试试这个。

val finalRegex = s"^(${regex1.regex})(?:(${regex2.regex}))$$".r
