RubyMine 2020.2 Beta is available!

To give you a picture of what the upcoming 2020.2 release will look like, here is a roundup of the most notable new features.

The links will take you to the EAP posts published over the last few months, which contain detailed descriptions of each feature.

Note that Beta builds are significantly more stable than EAP builds, but some issues might still arise. If you run into any, please report them to our issue tracker. No license is required to use this build.

Liquid template language support

The upcoming RubyMine 2020.2 includes basic support for the Liquid template language:

  • Support for Liquid syntax, including tags or braces like {{, {{-, {%, {%-. The IDE displays errors if there are any issues with the syntax.
  • Live templates allow you to insert frequently used constructions into your code.
  • Folding code blocks, such as tags or if-else statements.
  • Reformatting the code according to the requirements you’ve specified in the Code Style settings.
  • Support for comments, within {% comment %}...{% endcomment %} tags and inside the code blocks.
  • Support for named parameters, methods with question marks in their names, and more.

Ruby and Rails

  • Improved completion for standard library methods. RubyMine now suggests more accurate completion for a variety of methods, including Array#sort_by, Hash#each, and many others.
  • Support beginless ranges introduced in Ruby 2.7.
  • You can now launch the IRB console from Run Anything with Ruby 2.7 (RUBY-25603).
  • Completion in the Gemfile now shows only the latest local version of the gems (RUBY-25792).
  • RubyMine now displays a warning if you try to pass an incorrect number of parameters to stub methods, including Array.to_h(), Dir.each(), and others (RUBY-26096).
  • We’ve added the “ordinary parameter is defined” warning for all lambda cases in numbered parameters (RUBY-25405).
  • We’ve added type support for the not call in active record relation chains. Now when a where method is not provided any arguments, RubyMine will offer not as a completion (RUBY-25519).
