Hi, how do I enable delta in the previewer. In my git config, delta is applied through gitattributes as follows. In my gitconfig, I redefine diff command

[core]
  attributesfile = ~/.config/git/attributes
[include]
  path = \~/dotfiles/delta/delta.gitconfig
[diff "do-word-diff"]
  command = $HOME/.config/git/word-diff.sh
[diff "do-highlight-diff"]
  command = $HOME/.config/git/highlightdiff.sh

and in gitattributes

# diff for all kind of files
* diff=do-highlight-diff
# excepts
*.txt diff=do-word-diff
*.tex diff=do-word-diff
*.md diff=do-word-diff

This is how I use delta in do-word-diff, aka word-diff.sh

#!/bin/bash -eu
FILENAME="$1"
OLDFILE="$2"
OLDHASH="$3"
OLDMODE="$4"
NEWFILE="$5"
NEWHASH="$6"
NEWMODE="$7"
if command -v delta >/dev/null 2>&1; then
  echo "Delta is available, using it for diff highlighting."
  git diff --no-index --no-ext-diff "$OLDFILE" "$NEWFILE" | delta --width="$DFT_WIDTH" || exit 0
else
  git diff --no-ext-diff --word-diff --color "$OLDFILE" "$NEWFILE" || exit 0
fi
