skywriter - python to javascript

[Jopyth]

@kclemen Please use three backticks (```) for markdown if you paste your code, instead of one (`). Otherwise it will not recognize it as multi line code.

The problem are your regular print statements (e.g. print "Gesture is west to east"), these are also read by node, and they are not in the JSON format. You can comment these out, or maybe write them to a log file instead, if you want them to debug.

Thanks for the input. Indeed this was the mistake.

seems I’m missing still something. Now I get following error:

Ok, the script is performing without any errors at the moment.

Would somebody be so kind to check why console.log(“payload.action is up”); is not executed in MMM-skywriter.js?

I only get the message from node-helper.js : console.log(“[” + self.name + "] " + message.gesture);

Files can be found here: https://github.com/Kclemen/MMM-skywriter

[kclemen]

Node helper:
self.sendSocketNotification('gesture', message.gesture);

script:

Module.register("MMM-skywriter",{
	
	//	gesture_up: 0,
	//	gesture_right: 0,	

	// Override socket notification handler.
	socketNotificationReceived: function(notification, payload) {
			console.log ("socketnotificationreceived.")
		if (payload === "up"){
			console.log("test - up");
		}
		else if (payload === "left"){
			console.log("test - left");
		}
		else if (payload === "down") {
			console.log("test - down");
		}
} ```

Why is there no ccommunication between the helper and the script?	}

@kclemen Are you searching for the output in your browser console? The console.log("...") command from node_helper.js is shown on the console, however console.log("...") commands of your module will appear in your developer tools console in the browser (e.g. electron).

[kclemen]

@Jopyth said in skywriter - python to javascript:

developer tools console in the browser (e.g. electron).

Indeed, I want to see the output to verify the communication works.
Could you elaborate some more about the developer tools console?

ctrl + shift + i does the trick :)

@Jopyth you are a HERO. Last 2 days working on it, antd the trick was that simple!

[Jopyth]

@kclemen I was just pointing you in the right direction sometimes. ;) Best of luck with finishing the rest of the module.

ok, for now the last question ;):

Uncaught reference error: gesture_up is not defined. I understand what this means, but I can’t figure out why it says that :s

	
	// Default module config.
	defaults: {
		gesture_up: 0,
		gesture_right: 0,
		
	},

	// Override socket notification handler.
	socketNotificationReceived: function(notification, payload) {
		if (notification === "gesture_observed"){
			const self = this;
			
			console.log ("socketnotificationreceived.");
		
			//self.sendNotification(notification, payload);
			
			if (payload === "up"){
				
				if (gesture_up == 0) {
					
					if (gesture_up == 0){
						gesture_up = gesture_up+1;
						
						console.log("gesture_up is nu 1");

Try this.config.gesture_up instead

[kclemen]

This helps indeed for the error, thanks. But how to use it like I want? I mean, how can you do calculations within following up socketnotifications? It looks like with every gesture the this.config;gesture_up starts with the value 0.
