Scalastyle examines your Scala code and indicates potential problems with it. If you have come across Checkstyle for Java, then you’ll have a good idea what scalastyle is. Except that it’s for Scala obviously.
Scalastyle was recently used as part of the grading framework for the course Functional Programming Principles in Scala by Martin Odersky on Coursera.
