Delta is a pager that does Syntax highliting, better diff highliting and improved outputs of existing git commands. Highly recommended.
I'm using it like "git-ydiff-s" script in my PATH to use "git ydiff-s":
#!/bin/sh
git diff "$@" | ydiff -s --wrap --width=0
Installation is "sudo dnf install ydiff" or
curl -fsSL https://raw.github.com/ymattw/ydiff/master/ydiff.py > ~/bin/ydiff
chmod +x ~/bin/ydiff # (and change to python3)
