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
