Developers turn ideas, designs and patterns into source code, then compile the source code into executables. Decompiling turns executables back into source code, and deprogramming turns code back into designs and patterns. In this paper we introduce DeP, a tool for deprogramming software systems. DeP abstracts code into a dependency graph and mines this graph for patterns. It also gives program...

Low-code is an emerging concept that transforms visual representations into functional software, allowing anyone to be a developer. However, building low-code platform from scratch can challenging concerning the scarce available literature about topic. In this sense, paper proposes Open Low-Code Platform (OLP), solution enables regular users create applications. Furthermore, it presents low-cod...

Cognitive science emphasizes the strength of visual formalisms for human learning and problem solving. In software engineering, a clear, visual presentation of a system’s architecture can significantly reduce the effort of comprehension. Yet, all too often the documentation of complex software systems lacks clear identification of the architectural constituents and insufficiently relates them t...

The Microsoft Visual Studio IDE includes various tools for diagrammatic code understanding. I am currently involved in the final stages of preparing the next major version (11) for release later this year. In particular, I am working on a visual dependency analyzer that enables developers to dynamically build up a diagram from a particular piece of code or functionality. In designing and develo...

Our figure-rewriting visual language is extended by a general method so that it rewrites figures distributed on multiple hosts. With this language, network applications or distributed systems can be built simply by drawing figures as a graphical code on a single host. At run-time, the code is partitioned according to the number of target hosts and distributed on them. The partitioned codes then...
