Hi all! I’m currently looking for examples of large refactorings people have done/want to doo in open source projects for our paper on a new code search tool. The special part of this tool: You can search for “x >= low && x < hi” and it will also find “x < low || x >= hi”. More generally, it can find all kinds of semantic variants of whatever you’re searching for, even if it’s spread out over 20 lines, even if you add lots of indirection

Have you looked at Blender? They've done a couple of major UI redesigns over the past decade, which I imagine involved a large amount of refactoring.

That’s an idea; they probably have. Will think about how to find the kinds of commits we’re looking for
