Refactoring Nicely with Version Control

Question

A co worker of mine asked me to review some of my code and he sent me a diff file. I'm not new to diffs or version control in general but the diff file was very difficult to read because of the changes he made. Specifically, he used the "extract method" feature and reordered some methods. Conceptually, very easy to understand but looking at the diff, it was very hard to tell what he had done. It was much easier for me to checkout the previous revision and use Eclipse's "compare" feature, but it was still quite clunky.

Is there any version control system that stores metadata related to refactoring. Of course, it would be IDE and Programming Language specific, but we all use Eclipse and Java! Perhaps there might be some standard on which IDEs and version control implementations can play nicely?

Answer 1

Eclipse can export refactoring history (see 3.2 release notes as well). You could then view the refactoring changes via preview in Eclipse.
