Extending a Language Server With Sprotty Diagrams

In my last post, I described how we connected an Xtext-based language server for the YANG language into various editor clients. Today, I will show how we added graphical diagrams using the sprotty framework. These diagrams show a graphical overview on your YANG documents. They are automatically layouted and updated on changes. They allow to navigate between diagram and [...]

Generate Traced Code with Xtext

Xtext 2.12 is released on May 26th. As described in its release notes, a main novelty is an API for tracing generated code. Why Tracing?
