Xtext editors for binary files

 What does "4 + 1" mean? Well, for example itemis employees have been developing a Java bytecode editor with Xtext. This editor allows the contents of .class files to be made visible and editable. In the first part of this article I explained how the JBC editor is used. In this second part I want to discuss the technical problems that arise when you want to make a binary file editable with an Xtext-based editor.  Read more >

What's new in Xtext and Xtend 2.14: The journey of Tina Toolsmith

Tina Toolsmith is one of those typical developers. She loves to code in the office, on the train, during a long flight or even while sitting on her sunny terrace during her vacation. Tina takes great pleasure in using the latest programming languages, frameworks, and IDEs for manufacturing innovative solutions. Essential parts of her toolbox are Xtext and Xtend which she uses to tailor domain-specific languages for a wide variety of usage scenarios. Read more >

4+1 = CAFEBABE: Java Bytecode in Eclipse

What might itemis staff do on their project-free 4 + 1 day? They continue their education, often by working on their own ideas; I would like to introduce just such a project today. The goal was to build familiarity with Xtext and Xtend. The result is a Java Byte Code (JBC) Editor based on these technologies.   Read more >

Pro Tip: Implementing JUnit Test Cases in Xtend

  What makes a clean test? Three things. Readability, readability, and readability. Readability is perhaps even more important in unit tests than it is in production code. What makes tests readable? The same thing that makes all code readable: clarity, simplicity, and density of expression. Read more >

New File Wizard – easy to generate with Xtext 2.14

We have already shown on our blog how to generate a new project wizard with Xtext 2.14. Now it's also possible to create a comparable wizard, also based on templates, for creating DSL files in existing projects. Read more >

Generating a new project wizard with Xtext 2.14

Anyone who implements DSLs with Eclipse Xtext benefits from the fact that the necessary infrastructure is generated automatically from the grammar. This gives you an environment in which everything is provided for developing your own DSL with minimum effort. A mere grammar and two buttons later, you can start Eclipse, full of anticipation. It first asks what kind of project you want to create. Xtext has not answered this question yet, so you have a choice. Read more >

Code Mining Support in Xtext

One of the most notable new APIs in Eclipse Photon is called Code Mining. A code mining represents content (i.e. labels and icons) that are shown within the text editor, but are not part of the text itself. For example, within a method call statement a mining could display the name of parameters, or an icon above unit test methods could be shown that runs the test on clicking it. Read more >

New File Wizard – einfach mit Xtext 2.14 generieren

Dass Xtext 2.14 in der Lage ist, einen New Project Wizard zu generieren, wurde bereits im Blog berichtet. Aber auch ein vergleichbarer, ebenfalls auf Templates basierender Wizard, um DSL-Dateien in bestehenden Projekten zu erzeugen, ist nun neu dazu gekommen. Weiterlesen >

Xtext 2.14 adds support for JUnit 5

Unit tests written for Xtext DSLs are typically using Xtext’s testing infrastructure provided by the org.eclipse.xtext.testing bundle. Older tests might even still use the deprecated org.eclipse.xtext.junit4 bundle. Tests for DSLs need to inject a language specific IInjectorProvider with an @InjectWith annotation. Additionally a specialized JUnit runner, the XtextRunner, is used with the @RunWith annotation to run the test.  Read more >
