public method #foo(a <- T)) when the action is invoked on the method definition and as the parameter type when it’s invoked on a call. Regarding type variables, they show up as the type variable name (e.g. Now, if the method is described in RBS, RubyMine will display information about the parameters and return value in the documentation.

We’ve added the ability to view type information from RBS using the Quick Documentation popup (Ctrl+Q). Showing info from RBS in Documentation Tool Window You can easily edit signatures without you having to manage multiple files yourself.

The interaction is smooth and unobtrusive to your work. Upon completing the live template, you will be taken back to where you were in the Ruby code. In case of overloaded methods, one template per overload will be opened and you are able to tab between them. The feature will open the type signature file in a new tab and begin a live template on all of the type signature elements.

These actions are unavailable for classes and modules as these do not have type signatures directly themselves. This includes methods, attributes, instance/class variables, global variables, constants, and method aliases. The actions of editing and adding type signatures are both only applicable to declarations that actually have types. If a type signature is missing, you can add it using the quick-fix for the Missing Type Signature inspection. To edit type signatures, you can use the quick-fix available for the Mismatched Type inspection or an intention action on the declaration’s name in a Ruby file. We’ve implemented an easy way to edit and add new type signatures. There is no longer any need to switch between multiple files, Ruby, and RBS, just to write one method definition. You can learn more about RBS support in this article. In RubyMine 2022.3, we have simplified the process of writing methods with type signatures. Improved editing and adding method signatures to Ruby method definitions Here are some of the features in the upcoming release that we have not presented to you yet.
