I wasn't aware of this tool. I hope I'll get time to test it soon. It seems pretty good! Thank you. I'll try a short review on it. I hope I see you again on my blog. Coderfriendly Hello Ira and thank you for your comment.

I wasn’t aware of this tool. I hope I’ll get time to test it soon. It seems pretty good! Thank you. I’ll try a short review on it.

I hope I see you again on my blog.

Then, they have launched their algorithm and make a diff between what was expected and what their solution detects. AST diffs is hard and, in my opinion, it is still a research project. If you are aware of <a href="http://en.wikipedia.org/wiki/Model-driven_architecture" rel="nofollow">MDA</a>, you maybe know the <a href="http://www.eclipse.org/modeling/emf/" rel="nofollow">Eclipse EMF</a> project. One of its subprojects is <a href="http://www.eclipse.org/modeling/emft/?project=compare#compare" rel="nofollow">EMF compare</a> led by <a href="http://www.obeo.fr/?&lang=en" rel="nofollow">Obeo</a>: it enables to manage the merge two metamodels. You can get an overview of the UI <a href="http://www.eclipsecon.org/2008/?page=sub/&id=328" rel="nofollow">here</a> (the presentation is available). Hello Matt,

That is, they show a larger difference between the files than necessary? There's known approaches for visualising text diffs; I wonder how well AST diffs could be visualised?
