Understanding detailed changes done to source code is of great importance in software maintenance. We present Code Flows, a method to visualize the evolution of source code geared to the understanding of fine and mid-level scale changes across several file versions. We enhance an
Flow visualization has been a very active subfield of scientific visualization in recent years. From the resulting large variety of methods this paper discusses structure-based techniques. The aim of these approaches is to partition the flow in areas of common behavior. Based on
Electric power providing companies has to deliver reliable electric power in quality and at minimum cost for the competition in deregulated environment. To know the power system security and operating state, power flows in lines and bus voltage magnitude and angle are calculated
We present the Source Code History Navigator, a tool for visualizing the evolution of source code and comparing many revisions of a source code file. Our tool provides an overview of the entire history of a source file through a “history flow”-style visualization in which revisio
We have implemented intraprocedural control-flow and data-flow analysis of Java source code in a declarative manner, using reference attribute grammars augmented with circular attributes and collection attributes. Our implementation is built on top of the JastAdd Extensible Java
