Question

Is there an idiomatic Scala solution to obtain only the file names from File.listFiles?

Perhaps something like:

val names = new File(dir).listFiles.somemagicTrait(_getName) 

and have names become a List[String]?

I know I can just loop and add them to a mutable list.

Answer 1

I’m always wary of answering the wrong part of the question, but as Jean-Phillipe commented, you can get an array of the names from

new File(dir).list

and if you really need a list call toList on that.
