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