calendar not showing

[johnnewhouse]

Hi all,
I just got a raspberry pi zero w with the intention of making a smart mirror.
I used Jessie lite as the o/s.
Everything is up and running and I’ve got the modules displaying my regional specifc info.
However I am having an issue getting the calendar to appear.
I’m happy that the url is fine, I can see the correct output via curl. plus I’ve reverted back to the standard US-Holidays to try and troubleshoot.

I checked the errors log and seen the following:

** Message: console message: http://localhost:8080/modules/default/calendar//calendar.js @439: SyntaxError: Unexpected identifier ‘evt’. Expected either ‘in’ or ‘of’ in enumeration syntax.

I know absolutely nothing about code but this is at that point in the js file:

listContainsEvent: function(eventList, event){
	for(let evt of eventList){
		if(evt.title === event.title && parseInt(evt.startDate) === parseInt(event.startDate)){
			return true;

does any of this make sense to someone, and could possibly give me a few pointers?

this is what i have in my config.js for this module:

	{
		module: "calendar",
		position: "top_right",
		config: {
			colored: false,
			coloredSymbolOnly: false,
			calendars: [
				{
				url: "webcal://www.calendarlabs.com/templates/ical/US-Holidays.ics",
				symbol: "calendar"
				}
			]
		}
	},

thanks in advance. i’m really impressed with MM and the modules so far, I just hope my woodworking skills are up to doing it justice when I make a frame

@johnnewhouse
In my MM your posted calendar config is working.

@axled thanks for checking, that’s 1 aspect eliminated.
I wonder if there are some more pi zero tweaks I need

@johnnewhouse said in calendar not showing:

webcal://www.calendarlabs.com/templates/ical/US-Holidays.ics

in url should look like
url: “http://www.calendarlabs.com/templates/ical/US-Holidays.ics”,

@johnnewhouse the issue is in the for loop the keyword that is used is an ES6 variant: the let keyword. Flip it to var and voilá, golden!

i.e.:

listContainsEvent: function(eventList, event){
	for(var evt of eventList){
		if(evt.title === event.title && parseInt(evt.startDate) === parseInt(event.startDate)){
			return true;

Edit: I submitted a PR to fix this:

@johnnewhouse Could/Would you mark my last post as the answer? Not sure if you saw my previous comment, as I edited the post to @ you :)
