# 2) Now you use this pager in articleview using the hotkey <comma>+<i>

#set -o errexit
#set -o pipefail
#set -o nounset

image=$(grep -E -o "https?://[a-zA-Z0-9./?=_%:-]*" < "${1}" | tail -1)

# Detect terminal dimensions
dims="$(tput cols)x$(tput lines)@0x0"

kitty +kitten icat --clear
kitty +kitten icat --hold --scale-up --place "$dims" "$image"
