Implementation of a Graphical Modelica Editor with Preserved Source Code Formatting

Summary, in English

When an Integrated Development Environment (IDE) is developed, the support for multiple views of the same document is often essential. An example of this is Modelica models, as it should be possible to view and edit the same model in both its textual and graphical representation.



One implementation of Modelica is the open-source platform JModelica.org. It contains the JModelica.org IDE, that provides a text editor for Modelica code, based on the Eclipse platform.



In this paper, we present an implementation of a graphical editor for the JModelica.org IDE. Several challenges with implementing a graphical editor for Modelica are discussed. Among others, the difficulties in rendering Modelica diagrams and how to interact with existing frameworks in Eclipse are brought up.



A method for preserving the formatting of a modified source code file is also presented, which is essential when the model is altered in the graphical editor.
