enhanced-string-interpolator

An enhanced glob interpolator for Scala with format strings

read full usage in the documentation, or the original inspiration in my blog post

Note that JDK 17+ is required

Basic usage

import stringmatching.regex.Interpolators.r

"[23, 56, 71]" match
  case r"[${r"$xs%d"}...(, )]" => xs.sum // 150

Below is a table of all the useful format strings:

Format	Binding	Note
$foo	foo: String
$foo%d	foo: Int
$foo%L	foo: Long
$foo%f	foo: Float
$foo%g	foo: Double
$foo...(<regex>)	foo: Seq[String]	split by regex
$foo..!(<regex>)	foo: Seq[String]	drops first if empty
${r"$foo%d"}...(<regex>)	foo: Seq[Int]	match on each element
${r"$foo%L"}...(<regex>)	foo: Seq[Long]	match on each element
${r"$foo%f"}...(<regex>)	foo: Seq[Float]	match on each element
${r"$foo%g"}...(<regex>)	foo: Seq[Double]	match on each element
