Sorry for those of you who have already read my patch fragment blog posts. I'm re-listing them in this post for the sake of the Planet Eclipse aggregator.
In short, an OSGi fragment is a bundle that attaches to a host bundle . While patch fragments really aren't meant to be use to replace behavior in a host bundle , it's the most elegant hackish way to do just that.
The first blog post shows that I was able to make changes to all text editors using a patch fragment.
The second blog post hosts a screencast showing, step by step, how to build a patch fragment.
The third blog post shows the code required to create the effect from the first post.
So if you're coming here from Planet Eclipse, you may find these interesting.
