How to get a list with the Typesafe config library

As @ghik notes, the Typesafe Config library is Java based, so you get a java.util.List[String] instead of a scala.List[String]. So either you make a conversion to a scala.List:

import collection.JavaConversions._
val myList = modifyConfig.getStringList("mylist").toList

Or (probably less awkward) you look for a Scala library. The tools wiki links at least to these maintained libraries:

  • Configrity
  • Bee Config

(Disclaimer: I don’t use these, so you will have to check that they support your types and format)
