display-columns functionality in custom scripts

[punk-dev-robot]

Hi,
I wrote a custom rofi script for managing clipboard history and would really like to use an option similar to display-columns from dmenu mode. The cliphist commands that I use need id field from selection but I don't want to display it. I think that functionality could be very useful for anything that uses private id field for entries, and looks like it's already implemented for dmenu mode.

Here is my script as it may explain it better :)

I would appreciate any pointers how to achieve that.

I converted my script to dmenu one that runs in while true; loop but I think it's less elegant

#!/usr/bin/env bash
# Usage: rofi -show clipboard -config ~/.config/rofi/config-clipboard.rasi
# TODO: hide id column

print_lines() {
	tmp_dir="/tmp/cliphist"
	rm -rf "$tmp_dir"

	mkdir -p "$tmp_dir"

	read -r -d '' prog <<EOF
/^[0-9]+\s<meta http-equiv=/ { next }
match(\$0, /^([0-9]+)\s(\[\[\s)?binary.*(jpg|jpeg|png|bmp)/, grp) {
    system("echo " grp[1] "\\\\\t | cliphist decode >$tmp_dir/"grp[1]"."grp[3])
    print \$0"\0icon\x1f$tmp_dir/"grp[1]"."grp[3]
    next
}
1
EOF
	cliphist list | gawk "$prog"
}

case $ROFI_RETV in
# print lines on start
0)
	# needs to be enabled to handle custom keys
	echo -en "\x00use-hot-keys\x1ftrue\n"
	print_lines
	;;
# handle select line
1)
	cliphist decode <<<"$1" | wl-copy # && wtype -M ctrl -P v -m ctrl
	title=$(hyprctl -j activewindow | jq -r '.initialTitle')
	if [[ "$title" = "kitty" ]]; then
		coproc wtype -M shift -M ctrl -P v -m ctrl
	else
		coproc wtype -M ctrl -P v -m ctrl
	fi
	exit
	;;
# kb-custom-1 (Ctrl-Delete)
10) cliphist delete <<<"$1" && print_lines ;;
# kb-custom-2 (Alt-Delete)
11) cliphist wipe ;;
*) echo "exit retv: $ROFI_RETV" ;;
esac

Depending on the version of rofi, you can have an invisible field (info) passed in script mode, that gets set in an environment (ROFI_INFO) when that row is selected.. See manpage.

That looks like what I'm looking for, even though it's not as easy to use. I'll give it a try, thank you!

Thank you, my script is now much better :)
Some simple clipboard management with cliphist if anyone is interested:

#!/usr/bin/env bash
# Usage: rofi -show clipboard -config ~/.config/rofi/config-clipboard.rasi

print_lines() {
  tmp_dir="/tmp/cliphist"
  rm -rf "$tmp_dir"
  mkdir -p "$tmp_dir"

  cliphist list | while read -r line; do
    if [[ $line == *meta\ http-equiv=* ]]; then
      continue
    fi

    id=$(echo "$line" | awk '{print $1}')
    name=$(echo "$line" | awk '{$1=""; print $0}')

    if [[ "$line" =~ ^([0-9]+)[[:space:]]+\[\[\ binary.*(jpg|jpeg|png|bmp) ]]; then
      ext="${BASH_REMATCH[2]}"
      icon_path="$tmp_dir/$id.$ext"
      if ! [ -f "$icon_path" ]; then
        cliphist decode "$id" >"$icon_path"
      fi
      printf '%s\000icon\037%s\037info\037%s\n' "$name" "$icon_path" "$id"
    else
      printf '%s\000info\037%s\n' "$name" "$id"
    fi
  done
}

case $ROFI_RETV in
# print lines on start
0)
  # needs to be enabled to handle custom keys
  echo -en "\x00use-hot-keys\x1ftrue\n"
  print_lines
  ;;
# handle select line
1)
  cliphist decode "$ROFI_INFO" | wl-copy

  title=$(hyprctl -j activewindow | jq -r '.initialTitle')
  if [[ "$title" = "kitty" ]]; then
    coproc wtype -M shift -M ctrl -P v -m ctrl
  else
    coproc wtype -M ctrl -P v -m ctrl
  fi
  exit
  ;;
# kb-custom-1 (Ctrl-Delete)
10)
  cliphist delete <<<"$ROFI_INFO" && print_lines
  ;;
# kb-custom-2 (Alt-Delete)
11)
  cliphist wipe
