Presentation Transcript

  1. Interactive Visualization of Large Structured Development Environment Project Update – Nov 16 2005 By Anirban Sinha (Ani)

  2. Problem • Large software projects can get really complicated specially when large number of modules are added & integrated together. • It would be really helpful if we can develop a tool to visualize structures & method call sequences within the source codes using interactive trees. Project update presentation - 16th Nov 2005

  3. Proposed Solution – Original Plan • Use Prefuse Infovis toolkit to visualize program structures written in C as graphical models & add interactions. • To compensate for large complicated graphical structures for large projects, we add zooming & panning facilities. • For static analysis of code, I originally planned to use my previously designed code parser & add some modifications to it when required. Project update presentation - 16th Nov 2005

  4. Progress so far … • Configured Prefuse to work in eclipse. • Front end structure has been designed to load a file & display graphical visualization. Project update presentation - 16th Nov 2005

  5. Snapshots … Project update presentation - 16th Nov 2005

  6. Snapshot Continued … Project update presentation - 16th Nov 2005

  7. A look at milestones … Possibly miscalculated/unanticipated milestones?? True. – it definitely needs revision. Project update presentation - 16th Nov 2005

  8. Challenges So far/Diversions from Original Proposal … • Soon, realization dawned in that designing a static analyzer for C source code is in itself a large project. • Started looking for open source (so that I could tweak & port them with Prefuse), possibly cross platform & eclipse configurable analyzers. • Did not get any effective tools that analyze C codes, but got one that analyses exception flow control in Java codes - Jex. Project update presentation - 16th Nov 2005

  9. Jex - A Tool for Analyzing Exception Flow in Java Programs http://www.cs.ubc.ca/~mrobilla/jex/ • Originally designed by Martin P. Robillard during his masters research @ UBC. He is currently a faculty at McGill. • Analyzes the flow of exceptions in Java programs. • Is open source, written in Java & eclipse configurable. • Produces analysis results in text files which can be visualized. Project update presentation - 16th Nov 2005

  10. Current Work/Future Directions … • Currently working on to run Jex on UNIX system & run it on a sample java file & observe its output (having some CLASSPATH error). • Future work will mostly be concerned with tweaking Jex to produce output file compatible with Prefuse & tweaking Prefuse toolkit to bring about effective visualization of the exception flow structure. • Need to talk to Chris and/or Gail Murphy for further insights.
