Tamas works as an IT consultant at itemis AG in Lünen. He is interested in model-driven software development, especially in graphical and textual modeling solutions.
The Eclipse Graphical Editing Framework is a toolkit to create graphical Java applications either integrated in Eclipse or standalone. The most common use of the framework is to develop diagram editors, like a simple Mindmap editor we will create in the GEF ...
The Eclipse GEF team is happy to announce that version 5.1.0 of the Eclipse Graphical Editing Framework is part of the Eclipse 2019-06 simultaneous release:
With the Xtext framework, you can build DSL workbenches in just a few steps. However, sometimes you want to reuse model elements already defined in other formats or even in other languages. In this blog post I’m going to demonstrate typical scenarios when you’re ...
This blog post demonstrates use cases on combining EMF models with Xtext DSLs. It is based on Martin Fowler's secret compartment state machine implementation available via the Xtext Example Wizard.
The previous blog post introduced complex Graphviz *.dot graphs to add Eclipse GEF DOT-based visualization support to the Eclipse IDE. This blog post demonstrates the usage of the GEF DOT Graph View to add graphical representations to Xtext DSLs.
The previous blog post introduced the GEF DOT Editor that assists the user in editing Graphviz *.dot files and the GEF DOT Graph View that is capable of visualizing them in the Eclipse Workbench UI. This blog post continues with more complex DOT graphs to show ...
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, ...
In the Xtend programming language, visibility modifiers are unnecessary when they match the defaults. The public modifier is default on: Classes Interfaces Enums Annotatitons Constructors Methods The private modifier is default on: Fields
The Xtext grammar is the central component when developing DSL workbenches based on the Xtext framework. In case of complex DSLs, analyzing the graphical representation of *.xtext files can be useful to understand the structure of defined grammar rules.
Graphviz *.dot files are usual text files containing the textual representation of graph definitions. The structure of these *.dot files are defined by the DOT Language that provides more than 150 graph, subgraph, node and edge attributes to influence the graph ...
