    Modeling variability in template-based code generators for product line engineering
    (Modellierung 2016, 2016) Greifenberg, Timo; Müller, Klaus; Roth, Alexander; Rumpe, Bernhard; Schulze, Christoph; Wortmann, Andreas
    Generating software from abstract models is a prime activity in model-driven engineering. Adaptable and extendable code generators are important to address changing technologies as well as user needs. However, they are less established, as variability is often designed as configuration options of monolithic systems. Thus, code generation is often tied to a fixed set of features, hardly reusable in different contexts, and without means for configuration of variants. In this paper, we present an approach for developing product lines of template-based code generators. This approach applies concepts from feature-oriented programming to make variability explicit and manageable. Moreover, it relies on explicit variability regions (VR) in a code generator's templates, refinements of VRs, and the aggregation of templates and refinements into reusable layers. A concrete product is defined by selecting one or multiple layers. If necessary, additional layers required due to VR refinements are automatically selected.

    Visualizing MDD Projects
    (Software Engineering 2017, 2017) Greifenberg, Timo; Look, Markus; Rumpe, Bernhard
    Visualizing information enables humans to capture, understand, and analyze them in an efficient way. Tools providing such visualization possibilities are omnipresent in software develop- ment processes and still subject to current research. While visualization is widely tried in classical software development, the application to MDD is much less common, but still desperately needed. In this paper we outline an integrated and pervasive visualization approach for artifacts and software engineering tools as well as their static and dynamic dependencies by employing, extending, and combining well established visualization approaches to the MDD domain.

    Visualizing Model and Data Differences with Inline Diff Editors in an Enterprise Low-Code Platform
    (Modellierung 2024 Satellite Events, 2024) Butting, Arvid; Greifenberg, Timo; Hölldobler, Katrin; Kehrer, Timo
    Computing the difference between models is a foundation for solving various challenges in model-driven engineering. Models of low-code platforms are often of non-textual nature to be suited best for citizen developers as their creators. This poses special challenges for visualizing model differences. In this talk, we extend an approach for visualizing model differences via diff editors derived from the original model editors of the low-code platform by a novel kind of diff representation called inline diff editors. The approach improves on the previous approach through a concise form of presentation and by avoiding the generation of new user interface and data models for the editors.
