  1. Debugger Frontent for the SharpDevelop IDE Martin Koníček

  2. Current state of debugging • Breakpoints, watches, etc. • Basically the same in any current IDE

  3. What about data structures?

  4. What about data structures? • Debugger does not provide a useful view of reality

  5. Solution • Object graph visualizer

  6. Debugging collections • Very common case – collections of objects

  7. Debugging collections • Users have to expand each item to see anything

  8. Solution • Collection visualizer

  9. Problems faced • Determining how the graph looks in memory • The graph lives in a separate process, GC moves objects while the debugger is trying to analyze the graph • Dynamic layout and animation of the graph • Small graph changes -> small layout changes • Calculating “natural” edge routes

  10. Problems faced • Achieving reasonable performance • Interprocess communication very expensive • Need to handle large collections • Solution: everything is as lazy as possible. What is not on the screen is not being calculated.

  11. Results • Already integrated in the standard release of SharpDevelop • Received positive feedback • will evangelize the features to collect more feedback • Extensibility • users can plug in new visualizers

  12. Thank you for your attention Questions?
