A Bird’s View on Language Servers

To write computer programs different programming languages are used, often multiple languages for one piece of software. While programs can be written with very basic text editor like NotePad or vi, normally dedicated programming tools are used that give developers a more integrated and guided way of editing code.

A UML-agnostic Migration Approach: From UML to DSL

Over the last decade, open source frameworks for creating domain-specific language workbenches have improved significantly. Thereby, it has become easier to utilize model-driven software engineering based on domain-specific languages (DSL). However, many companies already adopted model-driven engineering at the beginning of the 21st century.  Read more >

Domain-specific visualization of textual models with Xtext and Sirius

Some people say graphical modeling is dead and textual modeling is the better maybe the only way. As an Xtext-enthusiast I would always argue that modeling should be done textually.  Read more >

Eclipse Xtext 2.13 is released!

Right on time for EclipseCon Europe the Xtext project managed to release its new version 2.13. Xtext 2.13 is the first version for the Eclipse Photon simultaneous release and was designed to fit well with the recently released Eclipse Oxygen.1a version. For users of older Eclipse versions, Xtext remains compatible back to Eclipse Luna. Read more >

About the Power of Open Source Development at Eclipse

As a project deeply integrated with Eclipse JDT, Xtext has sometimes also to use internal API. This is, for example, necessary to leverage best performance of accessing Java elements. We try to avoid this whenever possible sometimes even by duplicating the code, and we never faced a problem for several years in this regard. Read more >

Formatting for the Masses

Reading source code happens way more often than writing it. And reading code is a lot easier when it is well formatted. Linebreaks and indentations are guiding the reader and it is more obvious in which context things are happening. Doing formatting completely manually is simply not an option, especially for larger changes. For that reason general purpose languages, like Java, do have many different implementations for automatic code formatters or “pretty printers”.  Read more >

Xtext-Editor für binäre Dateien

Im ersten Teil dieser Serie habe ich erläutert, wie sich mit Hilfe von Xtext ein Java-Bytecode-Editor entwickelt und nutzen lässt, mit dem sich die Inhalte von.class-Dateien sichtbar machen lassen. In diesem zweiten Teil möchte ich auf die technische Problemstellung eingehen, die sich ergibt, wenn man eine Binärdatei mit einem Xtext-basierten Editor bearbeitbar machen möchte.

4+1 = CAFEBABE: Java Bytecode in Eclipse

Was treiben Itemiker eigentlich an ihrem projektfreien 4+1-Tag? Sie bilden sich weiter, häufig mit der Arbeit an eigenen Ideen – und genau solch ein Projekt möchte ich heute vorstellen. Das Ziel war, sich in Xtext und Xtend einzuarbeiten. Herausgekommen ist dabei ein auf diesen Technologien aufbauender Java-ByteCode-Editor (JBC-Editor). Weiterlesen >

From classical language design to language engineering with Xtext

The first high-level programming language Plankalkül (Plan Calculus) from Konrad Zuse was developed between 1942 and 1945. Since this time, a lot of languages have been developed and discarded. But how is a language defined? What is a domain specific or visual language? And have all languages equal definition parts? What is different if we use Xtext?  Read more >
