How to enable text file preview?

lfrc:

set preview
set drawbox
set icons
set previewer ~/.config/lf/previewer.sh
set cleaner ~/.config/lf/clear_img.sh

~/.config/lf/previewer.sh:

#!/bin/sh
draw() {
  ~/.config/lf/draw_img.sh "$@"
  exit 1
}

hash() {
  printf '%s/.cache/lf/%s' "$HOME" \
    "$(stat --printf '%n\0%i\0%F\0%s\0%W\0%Y' -- "$(readlink -f "$1")" | sha256sum | awk '{print $1}')"
}

cache() {
  if [ -f "$1" ]; then
    draw "$@"
  fi
}

file="$1"
shift

if [ -n "$FIFO_UEBERZUG" ]; then
  case "$(file -Lb --mime-type -- "$file")" in
    image/*)
      orientation="$(identify -format '%[EXIF:Orientation]\n' -- "$file")"
      if [ -n "$orientation" ] && [ "$orientation" != 1 ]; then
        cache="$(hash "$file").jpg"
        cache "$cache" "$@"
        convert -- "$file" -auto-orient "$cache"
        draw "$cache" "$@"
      else
        draw "$file" "$@"
      fi
      ;;
    video/*)
      cache="$(hash "$file").jpg"
      cache "$cache" "$@"
      ffmpegthumbnailer -i "$file" -o "$cache" -s 0
      draw "$cache" "$@"
      ;;
  esac
fi

file -Lb -- "$1" | fold -s -w "$width"
exit 0

~/.config/lf/clear_img.sh:

#!/bin/sh
if [ -n "$FIFO_UEBERZUG" ]; then
  printf '{"action": "remove", "identifier": "preview"}\n' >"$FIFO_UEBERZUG"
fi

You just need a case for text files in your preview script. Case can be for text/*. I would put it as * at the end of case statement to be used as default for all cases not matched above.
So in your case, that should look like this:

If you want to have syntax highlighting, you can use bat or highlight packages instead of cat
