But I think we should support both since ruby-debug is not (yet?) part of the ruby installers and needs to be installed with gem. Of course we will need RDT compatible releases of ruby-debug and I hope that we will have one soon. Yes, ruby-debug is the one with the native extension. Compared to the current implementation there is logic moved into C code resulting in less ruby calls (mainly for checking if a breakpoint is being hit). > I trying out org.rubypeople.rdt.launching/ruby/eclipseDebug.rb and > JRuby.

There you can see all the commands we send to the debugger and what results we expect. As mentioned before the main issue with ruby-debug was the threading model. With the test suite you will find out soon which scenarios will do or not.
