I haven't tested this, but maybe it will serve you as a starting point. Throw this script into $PATH (let's say into ~/.local/bin/diff-fmt): #!/bin/bash exec delta <(gofmt "$1") <(gofmt "$2") here I'm using delta as the difftool: https://github.com/dandavison/delta https://github.com/dandavison/delta and then, once: $ git config --global interactive.diffFilter diff-fmt
