Help Implementing Custom Feature w/Calendar
-
I am using the default clock module and the MMM-GoogleCalendar module. I use 3 instances of the MMM-GoogleCalendar modules–one for my personal calendar, one for a holiday calendar, and one for a birthday calendar. I recently coded a feature which makes a birthday appear in green if it is a week away, yellow if it is a day away, and red if it is that day.
Now, I want to made a custom feature which plays a song (in a .wav file) when there is at least one birthday on the current day. I would like the song to get played only when the user first uses the mirror on the day of the birthday.
To do this, I created a new notification that gets put out by the default clock module at midnight every day and it is called CLOCK_NEW_DAY. When the MMM-GoogleCalendar module sees that notification, it resets a flag that tells it that the song has already been played that day. My mirror blanks the screen when it is idle and sends a SCREEN_ON notification when the user is present. So, I added code to MMM-GoogleCalendar to look for a SCREEN_ON notification and when it sees it to set a boolean called screenOn and call this.updateDom()
I think I have all the code that I need in place, but for some reason, when I see a SCREEN_ON get generated, I can see it with MMM-ViewNotifications, but I don’t see the MMM-GoogleCalendar code receiving/responding to the notification. I’m not sure how to debug this, and I’d really appreciate any help you can offer. Thanks.

@raspberrypi9 does calendar have a message in notificationReceived?
you could use the code debugger to stop there

@sdetweil I am familiar with using debuggers in general programming and in embedded system, but this is my first time working on a web app. Where do I ge a debugger from and how do I attach/insert it into this process?
-
@raspberrypi9 the debugger is part of the browser developers window. ctrl-shift-i, or npm start dev, which opens the developers window
select the sources tab, find the module in the left nav, click the source file
click on line number for stop
ctrl-r to reload the page
blue right pointing arrow top right is run, circle is step next inst
arrows are step into/overmouse hover over variable shows value, including objects

@sdetweil did you make any progress?
