PDE Dependency View (SoC)

It has been too long since my last update. I meant to post this early this week, so this isn't the latest code. I will do another update this weekend.

Anyways, I thought I would give a brief overview of what the PDE Viz tool looks like and how to use it (My SoC project). The PDE Viz Tool is targeted at developers trying to understand the dependencies of their bundles. Once you get the tool (currently only available in source, but that will change soon) from here, you can find it using the now famous CTRL-3 :)

Once loaded, you can right click on the canvas to select a bundle.

For this example I selected ecore.


Producing a nice little graph.
I have also added a few small analysis tools, so if you ever wondered why javax.servlet was needed by EMF, you could see the dependency path:

A few other small notables in this version. I have updated my labels to use gradient colours. Also, if you double click a node it will refocus the graph on that node. The arrow keys (at the top of the view) can be used to navigate forward and backwards through the graph. Finally, I added a "Screenshot" action so you can save your dependency graph to a PNG.

I have tested this on some of the large IDEs built on Eclipse and it worked (albeit a little slow). My hunch is that it was not slow because of the large number of nodes, but rather because of the even larger number of edges. But for all the bundles I tested in Europa it worked without problems.
