Bulk adding items to Wunderlist using wunderline on Ubuntu MATE

If you use Wunderlist and want to be able to bulk-add tasks from a text file, first install and set up wunderline.

Now, to be able to right-click a text file containing one task per line on Ubuntu MATE, create a file called "wunderlist-bulk-add" in ~/.config/caja/scripts/ and make it executable. Paste the code below into that file.

(Note: it's possible that this would work in GNOME if you replaced "caja" with "nautius" in that path - let me know in the comments.)

#!/usr/bin/env bash

set -o pipefail

function nonblank()
{
    grep -v -e '^[[:space:]]*$' "$@"
}

for F in "$@"; do
{
    COUNT=$(nonblank "$F" | wc -l | awk '{print $1}')
    if [ "$COUNT" = "" ]; then
    {
        zenity --info --no-wrap --text="File $F does not exist"
    }
    else
    {
        zenity --question --no-wrap \
            --text="Add $COUNT items from $F to Wunderlist?"
        ANSWER=$?

        if [ "$ANSWER" = "0" ]; then
        {
            nonblank "$F" | \
                wunderline add --stdin | \
                zenity --progress --text "Adding $COUNT items to Wunderlist"
            SUCCEEDED=$?
            if [ "$SUCCEEDED" = "0" ]; then
            {
                zenity --info --no-wrap --text "Added $COUNT items."
            }
            else
            {
                zenity --error --no-wrap \
                    --text "Failed to add some or all of these items."
            }; fi
        }; fi
    }; fi
}; done
