RubyMine 2021.1

Ruby 3 RBS support and improved code completion

RubyMine 2021.1 now supports RBS and uses .rbs files in its Code Insight. This means code completion is improved for both Ruby’s standard library and user code with RBS definitions. You don’t even have to use Ruby 3.0 in your project. The only requirement is that you include the RBS gem in it.
