RubyMine 2022.1 EAP is Open!

Natalie Kudanova

The first Early Access Program of 2022 has started! 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 the first EAP build:

• Ruby and RBS
  • Support for new language features
  • New inspections
• YARD support
  • Improved autocompletion for the @overload tag
• Redesigned New Project dialog

  Ruby and RBS

  Support for new language features

  In v2022.1, we are adding support for the new language features introduced in Ruby 3.1 and RBS. Here are the new features included in the first EAP build:

  • Support for anonymous block argument forwarding. The IDE will show an error if this feature is used in any Ruby version before 3.1 or if there is no containing method that declares an anonymous block.
    
  • Support for generic type aliases added in RBS 1.8.
  • Support for resolve logic for RBS superclasses, which has been updated to make it consistent with Ruby: RUBY-29164.
  • Some small updates for one-line pattern matching, which is no longer experimental in Ruby 3.1. For example, this build adds support for nameless wildcards (* and **): RUBY-29131.

  New inspections

  This build adds several new inspections which check the usage of type variables in RBS.

  Invalid type argument usage. This inspection works similarly to the rbs validate command for the “Incorrect variance” errors. It reports type variables used as arguments in locations that their variance does not allow, so long as they are not marked as unchecked.

  

  Conflicting type variable variance. If there are several partial declarations of a class or a module, then their type variables must match in variance (in, out, or unchecked) between the declarations. The inspection checks if there are any mismatches.

  

  Incorrect type argument variance. This inspection reports cases when type arguments passed to an inheritance statement don’t match in variance with the declaring type variable.

  

  Tip: You can find full descriptions of the inspections mentioned above in Preferences/Settings | Editor | Inspections | RBS.

  

  YARD support

  Improved autocompletion for the @overload tag

  RubyMine understands the @overload tag and will suggest all of the declared overloads when showing parameter information.

  Starting with this version, autocompletion for the @overload tag adds the name of a method that you are describing.

  

  Redesigned New Project dialog

  In this release, we are working on improving the New Project dialog.

  The first IDE to implement the new design is IntelliJ IDEA 2022.1 EAP. If you are using it with the Ruby plugin, you can already check out the new version of New Rails Application and New Gem dialogs.

  

  RubyMine 2022.1 EAP1 comes with only the updated New Gem dialog, but other improvements are on their way.

  What do you think of the new design? Let us know in the comments or via your IDE’s Main menu | Help | Submit feedback action.
