RubyMine 2021.2 EAP Is Open!
Hello and welcome to RubyMine’s second Early Access Program of 2021!
Over the next couple of months, we will be publishing posts about the new features of the upcoming 2021.2 version. To learn about them as they come out, feel free to subscribe to the blog updates or follow us on Twitter.
As always, you are welcome to try the new features before the official release, and we are looking forward to hearing your feedback!
Here are the main highlights of this week’s build.
Ruby 3 RBS support
In this release, we aim to make working with RBS code more intuitive and efficient. Specifically, we’re making essential RubyMine features that you already use for regular Ruby code work for
.rbs files as well.
Write, read, and navigate RBS code with ease
RubyMine now automatically formats RBS code to make it look neat and easy to read. For example, RubyMine automatically adjusts indentation on new lines, and when you press backspace, it deletes blank spaces to the nearest indent position:
end keyword is automatically added for constructs like classes and modules:
Comments also work just like they do in
.rb files – pressing Enter adds a new commented line:
If you have several partial declarations in your
.rbs file, you can easily navigate between them using icons in the gutter:
Hovering a cursor over an RBS entity (while holding ⌘/Ctrl) now shows its description, and different icons indicate method visibility:
The Find usages action in RBS will also look for your searches in text occurrences, such as comments and string literals.
Get more relevant code assistance
This version provides more relevant code completion because it takes into account more information provided by RBS files. This includes block parameters, tuple types, type variables, data returned by the methods, and instance variables.
Enjoy intuitive refactoring
We’re continuing to implement refactoring features for RBS. For example, when you rename an element in RBS code, RubyMine will try to find and rename text occurrences like comments and string literals:
The Rename refactoring now skips the prefix when you rename interfaces and variables, just like it does for Ruby code.
Features like these make refactoring familiar and intuitive, especially for those who already take advantage of RubyMine’s capabilities. If you would like to learn more about refactoring in RubyMine, check out the refactoring topic in the docs or watch our video tutorial.
Catch more potential errors
Access to information stored in
.rbs files enables RubyMine to check code for more potential errors. For example, if an optional type is specified in RBS, RubyMine shows an error if you try to invoke a method on it without first checking that it’s non-nil:
RubyMine also keeps an eye out for errors in
.rbs files themselves, such as the inclusion of modules or declaration of singleton methods in interfaces, and warns you about them.
Early Access Program Key Facts
- The EAP version of RubyMine is free to use. It will expire in 30 days.
