RGen is a framework for Model Driven Software Development (MDSD)in Ruby. This means that it helps you build Metamodels, instantiate Models, modify and transform Models and finally generate arbitrary textual content from it.
RGen features include:
Supporting Ruby 1.8.6, 1.8.7 and 1.9.x
Metamodel definition language (internal Ruby DSL)
ECore Meta-metamodel with an ECore instance available for every Metamodel
Generator creating the Ruby metamodel definition from an ECore instance
Transformer creating Ruby metamodel classes/modules from an ECore instance
Instantiation of Metamodels, i.e. creation of Models (e.g. from XML)
Model builder, internal Ruby DSL
Model fragmentation over several several files and per-fragment caching
Model Transformation language (internal Ruby DSL)
Powerful template based generator language (internal Ruby DSL inside of ERB)
UML 1.3 metamodel and XMI 1.1 instantiator included
ECore XML support (XMI 2.0)
UML-to-ECore and ECore-to-UML transformation (UML class models)
Enterprise Architect support (UML1.3/XMI1.1)
