Our version is even older then 0.9.1, and has some modifications (mostly positioning fixes, so that part shouldn't be a problem). We also had to change the interfaces of some nodes, to add setters for variable names for example, but we didn't break any JRuby-functionality and have tons of unit tests, so migrating should be doable in time. What I fear quite a bit is the changes around the ScopeNode, which we use a lot. But we can work with Defn- and DefsNodes instead, so that should work too. There are also things that are easier to do with the newer version, I believe that LocalVarNodes now know their name and not just their 'count'. And there's still the issue of the comments we have to attach to the AST. But that has to wait until after the diploma thesis and our short trip to austria. > Or maybe you already knew this, then I'm sorry for smartassing around > ;-) ... That's no problem :-)
