Re: [RFC PATCH 0/1] Fuzzy blame

(resending in plain text mode, sorry for the noise)

Thanks Junio, that's super helpful!

A month or two ago I contacted the author of git-hyper-blame, Matt
Giuca, asking whether anyone had looked into adding the feature to git
blame. I didn't receive a response but maybe that prompted Barret
Rhoden's patch? Or maybe just a weird coincidence!

@Barret I see your patches are a nice translation of git-hyper-blame.
However could you give me your thoughts on the approach in my patch? A
comment in the git-hyper-blame source [1] says:
# This doesn't work that well if there are a lot of line changes within the
# hunk (demonstrated by GitHyperBlameLineMotionTest.testIntraHunkLineMotion).
# A fuzzy heuristic that takes the text of the new line and tries to find a
# deleted line within the hunk that mostly matches the new line could help.

My patch aims to implement this "fuzzy heuristic" so I'd love to get
your take on it.

Many thanks,
