Thinking time is over :-) I think this is very interesting. In my dreams it would be possible and easy for anyone to develop their own DSL and code generator on top of Sculptor. Then it would be possible to develop things like you describe without adding everything in the core of Sculptor. I can think of many use cases for this. One would be a to develop a DSL for the business domain (not only technical stuff) of something in your company. Then we are talking about higher level of abstraction!
We already have great possibilities to customize the code generation templates (and transformations). It is already possible to design your own meta model that refers to or extends sculptor meta model. This is what we do in gui meta model. It is already possible to develop a new xtext dsl with references to the sculptordsl. This is what we do in sculptorguidsl. The part that is missing is to easily be able to tweek existing sculptordsl. Maybe you only need a few additions to existing rule definitions. In new xtext this should be possible as described in xtext user guide. http://www.eclipse.org/Xtext/documentation/0_7_2/xtext.html#grammarMixins I have not tried, so I don't know if is usable. My suggestion is that you try to develop some of your ideas as a separate add-on. Maybe we need to adjust things in core sculptor to be able to support these kind of custom DSL/genererators even better. /Patrik Patrik Nordwall wrote: > > I need some mental thinking time on this :-) > > PaloT wrote: >> >> Hi Patrki, just needed time to do mental work.
