Type Touching – Types at your fingertips in IntelliJ Scala

Scala’s powerful type system helps you develop complex programs with less runtime errors. But sometimes understanding the types while programming becomes a challenge onto itself. I will show you how the Scala plugin for IntelliJ IDEA helps you get a grip on your types so that they can support your development flow instead of complicating it.

I will give a live programming tour of features supporting interaction with Scala’s type system, including:

  • type hints in parameters and return types
  • implicit conversions
  • type of selection
  • smart completion (types holes)
  • type mismatch diffs
  • type hierarchy
