Kermeta 2 provides a wrapper for Groovy. This allows to call this dynamic language directly from Kermeta.
TODO illustrate that on a small sample.
This tutorial will detail the following points:
create a kermeta project
configure the project to use the groovy wrapper
add kermeta code that will call a groovy expression that uses some kermeta elements.
add a sample ecore model in the project
add some kermeta code that will use groovy to navigate and call operations in the model.
Add kermeta code that extract the groovy expression from the model itself before applying it.
compile and run the kermeta application
