Summary
In this chapter we described scoping, which is the main mechanism behind visibility and cross-reference resolution. In particular, scoping and typing are often strictly connected and interdependent especially for object-oriented languages. We described both local and global scoping, and we showed how to customize these mechanisms using the SmallJava DSL as a case study.
In the next chapter we will show how you can create an Eclipse update site for your DSL implementation; this way, other users can easily install it in Eclipse. Moreover, we will describe the features provided by Xtext for building and testing DSLs headlessly, for example. in a continuous integration system.
