When I've been playing with colorMoved the thing I've found really
confusing is that the current config has confused two completely
unrelated things (at least, from a user perspective), what underlying
algorithm you use, and how the colors look.
I was helping someone at work the other day where they were trying:
git -c color.diff.new="green bold" \
-c color.diff.old="red bold" \
-c color.diff.newMoved="green" \
-c color.diff.oldMoved="red" \
-c diff.colorMoved=plain show <commit>
But what gave better results was:
git -c color.diff.new="green bold" \
-c color.diff.old="red bold" \
-c color.diff.newMoved="green" \
-c color.diff.oldMoved="red" \
-c diff.colorMoved=zebra \
-c color.diff.oldMovedAlternative=red \
-c color.diff.newMovedAlternative=green show <commit>
I don't have a public test commit to share (sorry), but I have an
internal example where "plain" will consider a thing as falling under
color.diff.old OR color.diff.oldMoved, but zebra will consider that
whole part only color.diff.old.
I see now that that might be since only the "zebra" supports the
*Alternative that it ends up "stealing" chunks from something that would
have otherwise been classified differently, so I have no idea if there's
an easy "solution", or if it's even a problem.
Sorry about being vague, I just dug this up from some old notes now
after this patch jolted my memory about it.
