Current jGRASP releases are versions 2.0.4_04 (February 12, 2018) and 2.0.5 Beta 3 (July 12, 2018).
If you haven't used the viewer canvas for Java, you will find this video useful: viewer canvas.

New Releases

Version 2.0.5 Beta introduces CSD support for new Java 11 syntax (var in lambda parameters), and UML support for changes to the class file format in Java 11.

Version 2.0.5 Alpha 6 introduces support for the new Java 10 'var' type inference mechanism, for both CSD generation and interactions. Note that syntactically 'var' is a predefined type, so the jGRASP editor window will correctly color it as an identifier rather than a keyword.


Microsoft OneDrive On-Demand Problems

If you are attempting to compile Java source files from a OneDrive folder on Windows 10, the compile may fail with a "not a file" message. You can correct this by turning off "Files on Demand" in the OneDrive settings, if you have sufficient disk space for all your OneDrive files. Otherwise, you will need to copy the source files to a normal folder to work on them, then back to the OneDrive folder when done.


Mac High Sierra Problems

Mac Java 6 does not work correctly on High Sierra. If you are encountering problems, please install Oracle JDK 8 or higher.


About jGRASP

jGRASP is a lightweight development environment, created specifically to provide automatic generation of software visualizations to improve the comprehensibility of software. jGRASP is implemented in Java, and runs on all platforms with a Java Virtual Machine (Java version 1.5 or higher). jGRASP produces Control Structure Diagrams (CSDs) for Java, C, C++, Objective-C, Python, Ada, and VHDL; Complexity Profile Graphs (CPGs) for Java and Ada; UML class diagrams for Java; and has dynamic object viewers and a viewer canvas that work in conjunction with an integrated debugger and workbench for Java. The viewers include a data structure identifier mechanism which recognizes objects that represent traditional data structures such as stacks, queues, linked lists, binary trees, and hash tables, and then displays them in an intuitive textbook-like presentation view.

jGRASP is developed by the Department of Computer Science and Software Engineering in the Samuel Ginn College of Engineering at Auburn University.


Note on Tutorials

We are in the process of updating the tutorials for jGRASP 2.0. The four updated tutorials that are available now cover most of the new features.
