VoiceControl module

@tyho, you can use setTimeout function to wait a for few seconds and then reset the text value. Something like that:

var self = this;
setTimeout(function(){
self.config.text = “”;
self.updateDom …
}, 3000);

thanks again it’s working :)

i made a notification.js:

notificationReceived: function(notification, payload, sender) {
		var self = this;
				if (notification === "go_to_sleep"){
            		this.config.text = "going to sleep...";
					this.updateDom(this.config.animationSpeed);
					setTimeout(function(){
						self.config.text = "";
						self.updateDom(self.config.animationSpeed);
					}, 3000);
        		}
				if (notification === "wake_up"){
            		this.config.text = "waking up...";
					this.updateDom(this.config.animationSpeed);
					setTimeout(function(){
						self.config.text = "";
						self.updateDom(self.config.animationSpeed);
					}, 3000);
        		}
    },

i have made a node_helper.js:

const NodeHelper = require('node_helper');
const exec = require('child_process').exec;

module.exports = NodeHelper.create({
  start: function () {
	      this.started = false
  }, 
 
  socketNotificationReceived: function(notification, payload) {
    if (notification === 'go_to_sleep' && this.started == false) {
            exec("/opt/vc/bin/tvservice -o", null);
	}
	    if (notification === 'wake_up' && this.started == false) {
            exec("/opt/vc/bin/tvservice -p", null);
	}
  }
}); 

It shows the command i speak for 3 seconds. But i can’t get the node helper working to actualy turn on and off my monitor. How can i bind this 2 modules? Or do i have to include it as a separate js file?

@tyho try this.sendSocketNotification('go_to_sleep', {}); in notification.js otherwise the node_helper doesnt’t get any msg and will not perform any action

[tyho]

Great! it’s working! thanks!

I still have a little problem. I want to register that if the monitor is on or off. It’s working very well except on the autosleep function that is loaded in the node_helper.

My notification.js

var awake = 1;
Module.register("notification",{

	// Default module config.
	defaults: {
		text: "",
		animationSpeed: 500,
	},
	notificationReceived: function(notification, callback) {
		var self = this;
				if (notification === "go_to_sleep" && awake === 1){
            		this.config.text = "going to sleep...";
					this.updateDom(this.config.animationSpeed);
					setTimeout(function(){
						self.sendSocketNotification('go_to_sleep', {});
						self.config.text = "";
						self.updateDom(self.config.animationSpeed);
					}, 1000);
					awake = 0;
					callback(awake);
        		}
				if (notification === "wake_up" && awake === 0){
					this.sendSocketNotification('wake_up', {});
            		this.config.text = "waking up...";
					this.updateDom(this.config.animationSpeed);
					setTimeout(function(){
						self.config.text = "";
						self.updateDom(self.config.animationSpeed);
					}, 5000);
					awake = 1;
					callback(awake);
        		}
				if (notification === "autosleep"){
					awake = 0;
					callback(awake);
        		}
    },
	
	// Override dom generator.
	getDom: function() {
		var wrapper = document.createElement("div");
		wrapper.innerHTML = this.config.text;
		return wrapper;
	}
});

and my node_helper.js

'use strict';
const NodeHelper = require('node_helper');
const exec = require('child_process').exec;
var timer;
function initialize() {

}
(function(){
	initialize();
			autosleep();
})();
function autosleep(){
	  timer=setTimeout(function(){
		  	var self = this;
				exec("/opt/vc/bin/tvservice -o", null);
				self.sendSocketNotification('autosleep');
			},  10*60*1000);
	  }

module.exports = NodeHelper.create({
  start: function () {  
  }, 
 
  socketNotificationReceived: function(notification) {

    if (notification === 'go_to_sleep') {
            exec("/opt/vc/bin/tvservice -o", null);
			clearTimeout(timer);
	}
	if (notification === 'wake_up') {
            exec("/opt/vc/bin/tvservice -p", null);
			exec("/bin/fbset -depth 8 && /bin/fbset -depth 16 ", null);
      		exec("/usr/bin/xrefresh",null);
			clearTimeout(timer);
			autosleep();
	}
  }
});

what i want is: if the autosleep function turns my monitor off, the variable awake in the notification.js set to 0.

any other suggestion on junky code are also welcome ^^

If you override socketNotificationReceived in your module then you should receive the message from node_helper and can reset your flag appropriately.

[tyho]

@alexyak how to override that module? I already call it with notifications === ‘autosleep’. And that notification gets send by the node_helper right? what am i missing?

[alexyak]

@tyho What I meant is you need to add socketNotificationReceived to your module notification.js.

[tyho]

@alexyak i can’t get it to work. it tested:
It sends sockets notifications from notifications.js to node_helper.js. But not from node_helper.js back to notifications.js.

Even if i put it in the start function of the node_helper.js:

start: function() { 
  this.sendSocketNotification("autosleep", {});
  }, 

it won’t get received it my notification.js:

socketNotificationReceived: function(notification) {
   if (notification === "autosleep") {
	  alert("autosleep received");
		awake = 0;
        		}
   	},

any idea? is it even possible to use it backwards?

[alexyak]

Try to put a call in your start method of the module (notification.js) to establish the connection with node_helper. Something like that:

this.sendSocketNotification(“CONNECT”, {});
