Subject: v2.11 new diff heuristic?
Date: Tue, 22 Nov 2016 08:42:36 -0600	[thread overview]
Message-ID: <CAHd499AjXh1YnVgBj_8j0fgvOgOn53y+sPBBy6y7mSM-+dCyVw@mail.gmail.com> (raw)

The release notes mention a new heuristic for diff:

* Output from "git diff" can be made easier to read by selecting
which lines are common and which lines are added/deleted
intelligently when the lines before and after the changed section
are the same. A command line option is added to help with the
experiment to find a good heuristics.

However, it lacks information on exactly how to use this new feature.
I dug into the git diff documentation here:

https://git-scm.com/docs/git-diff

It mentions a "--compaction-heuristic" option. Is this the new
heuristic outlined by the release notes? If not, which is it? Is the
compaction heuristic compatible with the histogram diff algorithm? Is
there a config option to turn this on all the time? For that matter,
is this something I can keep on all the time or is it only useful in
certain situations?

There's still so much more about this feature I would like to know.
