Automating Reminders with AppleScript18 Feb 2017
Occasionally, I need to provision a complete replica of our AWS production to get my work done. As you might imagine, this incurs a fairly hefty hourly charge and we try to avoid running this setup for any longer than necessary. Although I’ve tried to develop the habit of checking the AWS consoles before heading home for the day, I sometimes forget. We then run a completely unused production stack overnight, wasting a whole bunch of money and resources.
Automatically shutting down the replica every evening seemed like the obvious solution. But the trouble is that sometimes I do want to run the stack for a couple of extra hours or even overnight whilst a long-running test finishes.
And then it occurred to me: perhaps I should adapt my provisioning script to also create a task in Apple’s Reminders app.
Here’s the code:
# add_teardown_reminder.applescript tell application "Reminders" # Calculate date time for midnight today set currentDay to (current date) - (time of (current date)) # Calculate date time for 1700 today set theDate to currentDay + (17 * hours) # Select the relevant list in Reminders.app set myList to list "Work" tell myList # Create the reminder set newReminder to make new reminder set name of newReminder to "Teardown test servers" set remind me date of newReminder to theDate end tell end tell
This script calculates a date time for today at midnight, adds 17 hours to get a due date of “5pm today” and then adds the task to the Work list in Reminders.app.
Running the script from a shell script is simple:
I’d not dabbled with AppleScript very much before, but getting this done took around 10 minutes. The “Open Dictionary” tool in Apple’s Script Editor is an excellent way to explore the APIs provided by Reminders.app (and other applications), and I picked up a few tips from Federico Viticci.
Best of all, our AWS account won’t be wasting midnight oil anymore.
