Create a Vector[Vector[Char]] from a file

Question

I'm a newbie, trying to read a file and create a Vector[Vector[Char]]. Each line of the file should result in a different vector.

Here's what I've come up with:

val empty: Vector[Vector[Char]]       = Vector()
lazy val lines: List[String]          = Source.fromFile("test.txt").getLines.toList
lazy val vecList: List[Vector[Char]]  = lines.map(str => Vector(str: _*))
lazy val vector: Vector[Vector[Char]] = vecList.foldRight(empty) (_ +: _)

The file will never be large, so scalability isn't an issue. The above code seems to work, but I feel like it's going all around the barn. Is there a simpler, more direct way to do this?

Answer 1

The following is a solution using Scala 2.10:

source.getLines.to[Vector].map(_.to[Vector])
