How do I list all files in a subdirectory in scala?

Question

Is there a good \"scala-esque\" (I guess I mean functional) way of recursively listing files in a directory? What about matching a particular pattern?

For example re

Answer 1

Scala is a multi-paradigm language. A good "scala-esque" way of iterating a directory would be to reuse an existing code!

I'd consider using commons-io a perfectly scala-esque way of iterating a directory. You can use some implicit conversions to make it easier. Like

import org.apache.commons.io.filefilter.IOFileFilter
implicit def newIOFileFilter (filter: File=>Boolean) = new IOFileFilter {
  def accept (file: File) = filter (file)
  def accept (dir: File, name: String) = filter (new java.io.File (dir, name))
}
