TL; DR: Xtext sources are now in a single Git monorepo (https://github.com/eclipse/xtext), and the build infrastructure is based entirely on Maven/Tycho (Gradle is not used anymore). Background A few years ago, Xtext sources were split into 6 separate GitHub repositories. I did not take part in that decision (I guess at that time, I wasn’t […]
If you update to Xtext 2.27.0 and have compiler tests for your Xbase DSL that assert the output of the compilation, you’ll get lots of failures after the update. I am guilty of that đ Well, for a good reason, at least đ In fact, I worked on this issue: https://github.com/eclipse/xtext-extras/issues/772 and its fix is […]
The second edition of the Xtext book, Implementing Domain-Specific Languages with Xtext and Xtend, was published at the end of August: https://www.packtpub.com/web-development/implementing-domain-specific-languages-xtext-and-xtend-second-edition. So… get it while it’s hot đ Please, see my previous post for details about the novelties in this edition. Sources of the examples are on github: https://github.com/LorenzoBettini/packtpub-xtext-book-2nd-examples. Hope you’ll enjoy the book!
The second edition of the Xtext book should be published soon! In the meantime it is already available for preorders. At the time of writing, you can benefit for discounts and preorder it at 10$. I’ll detail the differences and novelties of this second edition. But, first things first! A huge thank you to Jan Köhnlein, for reviewing […]
In this blog post I’ll describe my experience in preparing an Oomph setup for a non-trivial Xtext project, Xsemantics. This setup was kind of challenging because of the following features of my project, but I guess most of them can be found in any Xtext project: generated sources are not stored in the Git repository […]
Hi I’d like to spread the world about the “Day Against DRM” campain from Packt Publishing:Â http://bit.ly/1EQrkF7 All ebooks and videos are 10$ You could take a chance to get my Xtext book “Implementing Domain-Specific Languages with Xtext and Xtend“. đ
I recently started to play with Sonarqube to reduce “technical debt” and hopefully improve code quality. I’d like to report on my experiences about using Sonarqube to analyze Xsemantics, a DSL for writing rule systems (e.g., type systems) for Xtext languages. I was already using the Jenkins Continuous Integration server, and while building I was […]
This is a followup of my previous post, Switching from an inferred Ecore model to an imported one in your Xtext grammar. The rationale for switching to manually maintained metamodel can be found in the previous post. In this post, instead of using an Ecore file, we will use Xcore, Xcore is an extended concrete syntax […]
When you use Xtext for developing your language the Ecore model for the AST is automatically derived/inferred from the grammar. If your DSL is simple, this automatic meta-model inference is usually enough. However, there might be cases where you need more control on the meta-model and in such cases you will want to switch from an inferred Ecore […]
Up to now, I was always putting the Xtend generated Java files in my git repositories (for my Xtext projects), since I still hadn’t succeeded in invoking the Xtend standalone compiler in a Buckminster build. Dennis HĂŒbner published a post with some hints on how to achieve that, but that never worked for me (and apparently it […]
My book on Xtext, âImplementing Domain-Specific Languages with Xtext and Xtendâ is now available on Packt website! Get it while it’s hot! đ You can find the outline and an example chapter at http://www.packtpub.com/implementing-domain-specific-languages-with-xtext-and-xtend/book Many thanks to the reviewers of the book: Jan Koehnlein, Henrik Lindberg, Pedro J. Molina, and Sebastian Zarnekow! The sources of the examples presented […]
I’m happy to announce that my book “Implementing Domain-Specific Languages with Xtext and Xtend” is now available for pre-order on Packt website! đ http://www.packtpub.com/implementing-domain-specific-languages-with-xtext-and-xtend/book
I know that Xtext 2.4 has not been released yet, but I could not resist blogging about a very cool new feature in Xbase: improved automatic import functionalities! Actually, import functionalities were already great when using Xbase also in previous versions of Xtext, but now they provide a much better experience for the user of […]
One of the new cool features which came with Xtext 2.3.0 is a wizard which generates all the artifacts to build your Xtext DSL project with Buckminster; this will allow you to easily build your Xtext project p2 site and also to build your project and its tests headlessly (e.g., from the command line, and, […]
