JGRASP was created by James Cross and Larry Barowski at the Department of Computer Science and Software Engineering in the Samuel Ginn College of Engineering atĪuburn University. UML diagrams for Java, with interactive dependency information. Reachability and content complexity, which can be displayed individually. The metric includes common measures, such as jGRASP generates CPGs for both Java and Ada. Its purpose is to aid in identifying overly complex areas of source code. The Complexity Profile Graph (CPG) is a statement-level complexity diagram. ![]() Multiple viewers can be combined on a single viewer canvas window and the contents can be saved to file. Other viewers show, for example, aĬolor swatch for a Color, the image for an icon, and the binary details of a double. Common data structures are automatically identified and displayed structurally. The result is animated when changes occur, as when a node is added to a linked list. Structural views of linked data structures display local variable nodes and their relation to the main structure. Structural views show the internal structure of For example, a content-based view shows ArrayList and LinkedList in an identical way, as a list of elements. The Java object viewers in jGRASP provide interface-based, structural, and other views ofĭata structures and other objects and primitives during debugging and workbench operations. The editing window provides CSD-basedįolding and a "context hint" feature that displays the first line of a code structure that is off-screen when the mouse is hovered over its CSD structure. Its purpose is to improve the readability of source code. It can be configured to work with most free and commercial compilers for any programming language.Ĭontrol Structure Diagram (CSD) is a control flow diagram that fits into the space normally taken by indentation in source code. The jGRASP web site offers downloads forįor languages other than Java, jGRASP is a GRASP (Linux, UNIX) and pcGRASP (Windows) are written in C/C++, whereas jGRASP is written in Java (the "j" in jGRASP means it runs on the JVM). Java Virtual Machine (Java version 1.8 or higher). The runtime data structure visualizations are also available as plugins for IntelliJ IDEA, Android Studio, and Eclipse. It produces static visualizations of source code structure and visualizations of It looks like the site has some good documentation.Development environment that includes the automatic creation of Having never used jgrasp before, I can't give a definitive answer to your questions. This installation help doc seems to talk a bit about setting up the compiler based on specific installations. (You can edit this but be sure not remove anything you don't know about.) d If you need help in setting environment variables then what operating system are you using?ĮDIT: In my shell on Ubuntu 7.10 simply typing $PATH will show defined paths. jGRASP is implemented in Java, and runs on all platforms with a Java Virtual Machine (Java version 1.5 or higher). Yes, to solve the debugging problem it looks like you need to tell it where to find the JDK you have installed. JGRASP is a lightweight development environment, created specifically to provide automatic generation of software visualizations to improve the comprehensibility of software. I don't know how to change my PATH or set an environment variable. If anyone could help that'd be wonderful :guitar: Can anyone help? This was my IDE of choice in Windows because of it's simplicity but also because it has a GREAT visual debugger that I find very useful when I'm making trees. ![]() I've installed the JRE and JDK (both 1.6) from Synaptic. How can I get jgrasp to debug my programs? ![]() You can also set a 'JGRASP_JAVA' environment variable to force jgrasp to use a particular Java version If you have the full JDK installed, you may need to change your PATH to correct this. It appears you are running jgrasp under the JRE (not JDK), or a version of Java that does not support integrated debugging. Secondly, when I try to debug I get this error message and debugging doesn't work: ![]() ISO8859-1 (Latin-1) encoding will be used.Ĭharacter display, printing, I/O, and cut-and-paste behavior may not be as expected.ĭoes anyone know what this means or how to fix it? First, I get this message everytime I start jgrasp:ĭefault system character encoding uses multi-bye characters or is not one-to-one.Ĭurrently, jgrasp CSD windows can not handle such encodings.
