Hello guys,
Not long ago we wrote about the coming YARD support in RubyMine, and today it's time to share some more with you. So, what have been done since then. First, RubyMine supports any syntax of types annotations supported by YARD. More details can be found at http://yardoc.org/features.html.
You can annotate either return types or method parameters with types. Moreover you can use autocompletion for tag names, method parameters, types, anywhere you may need. Of course complex namespaces and even alternative types are supported out of the box.
Let me show you some screenshots of all
