JRuby+Truffle is an implementation of Ruby using Truffle. Unlike other Truffle implementation projects, we are doing this within the existing open source project implementing Ruby in Java, JRuby. We will talk about the challenges and opportunities of integrating Truffle into an existing JVM language implementation project. What code can be re-used? Why isn’t it always easy to use existing parts of the implementation? Can we take an easier route if we are happy to accept lower performance? Can we maintain compatibility?
