Some Aspects about Visualization of Natural Semantics for a Selected Domain-Specific Language

In this article, we present a practical way to visualize natural semantics calculations for a selected domain-specific language for motion control of a robot in an orthogonal grid. Natural semantics is important from the point of view of verifying the properties of the language and for expressing the dynamics of the calculation and the construction of a set of states during the calculation. Domain-specific languages are used more and more in practice, therefore their inclusion in the curriculum of the subject Semantics of Programming Languages is a significant innovation of the traditional way of teaching the semantics of (mostly) imperative languages. In the article, we present the basics of the natural semantics of the robot language and its software visualization. For this, we have developed an application, the use of which is of great importance in the teaching itself and allows students to easily understand the basics of formal semantics thanks to interactivity.
