a script to edit a url inline using whiptail, then open it in a browser

open-edited-url.sh

# check what's available for opening the url.
# sensible-browser requires an environment variable :(
# see xdg-open spurce: https://github.com/freedesktop/xdg-utils
# todo: maybe use a second whiptail checklist to pick browser?
# todo: a chooser for termux-open options (send/view, chooser)
for app in $BROWSER termux-open xdg-open firefox elinks links2 links lynx w3m
do
    if
        type $app > /dev/null 2>&1
    then
	opener=$app
	break
    fi

URL=$(whiptail --inputbox "Edit your url here:" 8 70 "$1" \
        --title "Edit: $1" 3>&1 1>&2 2>&3)
# The `3>&1 1>&2 2>&3` is a small trick to swap the stderr with stdout

# Now to check if the user pressed OK or Cancel
exitstatus=$?

echo Original URL: "$1" # in case the user wants to use it again

if [ $exitstatus = 0 ]; then
    echo "New URL:      $URL"
