After git config --global interactive.diffFilter diff-highlight my .gitconfig:
# This is Git's per-user configuration file.
[user]
name = Vitaly Zdanevich
email = vitaly.zdanevich@xxx.com
[core]
excludesfile = /Users/vitaly/.gitignore_global
[filter "lfs"]
clean = git-lfs clean -- %f
smudge = git-lfs smudge --skip -- %f
process = git-lfs filter-process --skip
required = true
[diff]
tool = vimdiff
context = 20
[difftool]
prompt = false
[interactive]
diffFilter = diff-highlight
But in git commit -p and git add -p I see the same diff line-by-line without color in default terminal.app:
Also I tried:
git -c interactive.diffFilter="git diff --color-words" add -p
And get:
fatal: mismatched output from interactive.diffFilter
hint: Your filter must maintain a one-to-one correspondence
hint: between its input and output lines.
My git version is 2.17.2 (Apple Git-113) on macOS 10.14.1 from the official Command Line Tools, I prefer simplicity so not from the Brew.
