jGRASP is a lightweight code development environment that makes reading source code easier for programmers. It uses Control Structure Diagramming (CSD) and Java object viewers to allow data structures and other objects to be viewed at will during debugging and workbench testing.
jGRASP is a feature-rich environment for writing code in many common programming languages (Java, C, C++, Objective-C, Ada, and VHDL) on most platforms (Windows, Mac OS, and Linux). It’s like have a bird’s eye view of your code.
Instantaneous access to information about data structures and other objects makes visualizing the code’s purpose and structure much easier for the original author as well as anyone charged with editing or altering the code. A wealth of information about any object is a click or hover away thanks to integrated and instantaneous use of Controls Structure Diagrams (CSD) and Complexity Profile Graphs (CPG).
Simply hover over a code structure to get CSD-based information about that structure. Viewable information includes a bevy of content or structure data: details about data types, values, links and complexity. All of this information can be presented through customizable dynamic object viewers that can be combined and saved to files.
Unlike other visualization software, jGRASP uses Java and can run on any platform with a Java Virtual Machine (including Windows, Mac OS and Linux).
The Complexity Profile Graph (CPG) allows a user to identify complex areas of source code. Full integration of the CPG with the editing window means accessing this feature is simple and intuitive.
jGRASP is open source freeware and was developed by a research grant from the National Science Foundation.
