Summary
In this chapter, we showed many advanced topics and techniques related to an Xtext DSL implementation. When your DSL grows in features, you may want to take some of the techniques described in this chapter into consideration. These could be useful to make the implementation cleaner and more maintainable, to make a few aspects easier to implement and to improve the overall performance.
Finally, we showed how Xbase can be extended with new expressions, by customizing the type system, the validator, and the compiler accordingly.
