TruffleRuby is high performance implementation of the Ruby programming language, compatible with MRI 2.4.4.

TruffleRuby is progressing fast but is currently probably not ready for you to try running your full Ruby application on. However it is ready for experimentation and curious end-users to try on their gems and smaller applications.

TruffleRuby runs Rails, and passes the majority of the Rails test suite. But it is missing support for Nokogiri and ActiveRecord database drivers which makes it not practical to run real Rails applications at the moment.

The Ruby language components can be installed in GraalVM using the gu utility.

Release Notes

  • TruffleRuby is now compatible with Ruby 2.4.4.
  • object.class on a Java Class object will give you an object on which you can call instance methods, rather than static methods which is what you get by default.
  • Java.import name imports Java classes as top-level constants.
  • Coercion of foreign numbers to Ruby numbers now works.
  • to_s works on all foreign objects and calls the Java toString.
  • to_str will try to UNBOX and then re-try to_str, in order to provoke the unboxing of foreign strings.
  • More details in https://github.com/oracle/truffleruby/blob/master/CHANGELOG.md
