Regex String Interpolation Utility

==================================

[![Maven Central](https://maven-badges.herokuapp.com/maven-central/dev.bgahagan/scala-regex-interpolation_2.13/badge.svg)](https://maven-badges.herokuapp.com/maven-central/dev.bgahagan/scala-regex-interpolation_2.13)

A small library that allows [interpolation](https://www.scala-lang.org/files/archive/spec/2.13/08-pattern-matching.html#interpolated-string-patterns) of regex capture groups in `match` statements.

The nth interpolant (e.g. `$group1`) will match against the nth capture group in the regex.

Example

-------

```

import dev.bgahagan.regex.intrpl._

"hello world" match {

  case r"(\w+)$group1 (\w+)$group2" => 

    println(group2)

}

```

Outputs:

```

world

```

Design Notes

------------

* The regex is parsed and compiled on each `match` invocation.
