Since its inception in 2008, the Xtext framework has become a de-facto standard when it comes to domain-specific languages that run on the Java virtual machine. Its mature editing support in Eclipse, VS Code, and other LSP-based editors has proven a success factor for its adaption throughout different industries. Truth be told, it became quiet around Xtext in the past years. Development is stalled, even basic maintenance is in jeopardy, and it's hard to predict its future.
In this presentation, I want to highlight key events in the 15-year-long history of Xtext and identify learnings that might apply to other open-source projects, too - both relevant to maintainers but also to consumers of the technology. Having my crystal ball with me, I’ll also share my thoughts about the further evolution of the Xtext framework.
