assign a symbol to a module

[strawberry 3.141]

@dominic ou can add a fontawesome icon in the header like the following lines here https://github.com/fewieden/MMM-Fuel/blob/master/MMM-Fuel.js#L49

and add

getStyles: function () {
        return ["font-awesome.css"];
},

@strawberry-3.141 said in assign a symbol to a module:

getStyles: function () {
return [“font-awesome.css”];
},

I add:

 var header = document.createElement("header");   // in the getdom function and 

getStyles: function () {
        return ["font-awesome.css"];
},

in the .js file. And now I have to do ?

how do i musst edit the config file ?

getDom: function() {
	var wrapper = document.createElement("div");

	var symbol =  document.createElement("span");
	symbol.className = "fa fa-home";
	wrapper.appendChild(symbol);

	return wrapper;
}

This will result in a “house symbol”

Thanks. When i add the code, i have the “house” but i have a getdom function with the following code…

getDom: function(){
		
		var wrapper = document.createElement("div");
		if(this.dataFile){
                        var humidityRegExp = /Humidity = (.*?) %/ig;
                        var humidity = humidityRegExp.exec(this.dataFile)[1];

                        var temperatureRegExp = /Temperature = (.*?) *C/ig;
                        var temperature = temperatureRegExp.exec(this.dataFile)[1];
			wrapper.innerHTML = "r.F.: " + humidity + "%, Temp.: " + temperature + "°C";
		} else {
			wrapper.innerHTML = "No data";
		}
		return wrapper;
	},

…how do I implement the code in this?

[yawns]

like this:

getDom: function() {
	var wrapper = document.createElement("div");
	if(this.dataFile){
		var humidityRegExp = /Humidity = (.*?) %/ig;
		var humidity = humidityRegExp.exec(this.dataFile)[1];

		var temperatureRegExp = /Temperature = (.*?) *C/ig;
		var temperature = temperatureRegExp.exec(this.dataFile)[1];

		var spacer = document.createElement("span");
		spacer.innerHTML = " ";
		var temperature_symbol =  document.createElement("span");
		temperature_symbol.className = "fa fa-home";
		var humidity_symbol =  document.createElement("span");
		humidity_symbol.className = "fa fa-tint";

		wrapper.appendChild(temperature_symbol);
		var temperature_text = document.createElement("span");
		temperature_text.innerHTML = " " + temperature + "°C";
		wrapper.appendChild(temperature_text);

		wrapper.appendChild(spacer);

		wrapper.appendChild(humidity_symbol);
		var humidity_text = document.createElement("span");
		humidity_text.innerHTML = " " + humidity + "%";
		wrapper.appendChild(humidity_text);
	} else {
		wrapper.innerHTML = "No data";
	}
	return wrapper;
},

Should give you a house symbol for temperature inside and a droplet for humidity.

I need add a symbol to text (before or behind).

Code:

getDom: function() {
		
		var header = document.createElement("header");
		var wrapper = document.createElement("div");
		if(this.config.title !== false){
			var title = document.createElement("header");
			title.innerHTML = this.config.title || this.name;
			wrapper.appendChild(title);
		}
		var logs = document.createElement("table");

		for (var i = this.messages.length - 1; i >= 0; i--) {
			//Create callWrapper
			var callWrapper = document.createElement("tr");
			callWrapper.classList.add("normal");

			
			var icon =  document.createElement("td");
			
			if (this.messages[i].type === "INFO"){
				icon.className = "fa fa-info";
			}
			else if (this.messages[i].type === "WARNING"){
				icon.className = "fa fa-exclamation";
			}
			else if (this.messages[i].type === "ERROR"){
				icon.className = "fa fa-exclamation-triangle";
			}
			else {
				icon.className = "fa fa-question";
			}
			
			
			
			//Set caller of row
			var caller =  document.createElement("td");
			caller.innerHTML = "[" + this.messages[i].type + "] " + this.messages[i].message + " " + wrapper.appendChild(icon);
			caller.classList.add("title", "small", "align-left");
			if(this.config.types.hasOwnProperty(this.messages[i].type)){
				caller.classList.add(this.config.types[this.messages[i].type]);
			}
			callWrapper.appendChild(caller);

			//Set time of row
			var time =  document.createElement("td");
			time.innerHTML = this.config.format ? moment(this.messages[i].timestamp).format(this.config.format) : moment(this.messages[i].timestamp).fromNow();
			time.classList.add("time", "light", "xsmall");
			callWrapper.appendChild(time);

			//Add to logs
			logs.appendChild(callWrapper);
		}
		wrapper.appendChild(logs);
		return wrapper;

This is effect:

What is wrong?

Hi @Plati

The solution depends on how you want to display the table.

Do you want

• 3 columns in the following order: | Icon | Message | Time |
• Or 2 columns laid out as follows: | Message Icon | Time |

[Plati]

Hi @ianperrin

| Icon | Message | Time | should be ok

[ianperrin]

@Plati said in assign a symbol to a module:

Hi @ianperrin

| Icon | Message | Time | should be ok

In that case, try this

		var iconCell = document.createElement("td");

		var icon =  document.createElement("i");
		if (this.messages[i].type === "INFO"){
			icon.className = "fa fa-info";
		}
		else if (this.messages[i].type === "WARNING"){
			icon.className = "fa fa-exclamation";
		}
		else if (this.messages[i].type === "ERROR"){
			icon.className = "fa fa-exclamation-triangle";
		}
		else {
			icon.className = "fa fa-question";
		}

		iconCell.appendChild(icon);
		callWrapper.appendChild(iconCell);
		
		//Set caller of row
		var caller =  document.createElement("td");
		caller.innerHTML = "[" + this.messages[i].type + "] " + this.messages[i].message;

[ianperrin]

You could also consider making the icon configurable via the options,

First add the default values for the options

	defaults: {
		max: 5,
		format: false,
		types: {
			INFO: "dimmed",
			WARNING: "normal",
			ERROR: "bright"
		},
		icons: {
			INFO: "info",
			WARNING: "exclamation",
			ERROR: "exclamation-triangle"
		}
	},

Then change the code to create the icon (and for bonus points, set class for the icon to the same as the message.

		var iconCell = document.createElement("td");
		var icon =  document.createElement("i");
		if(this.config.icons.hasOwnProperty(this.messages[i].type)){
			icon.classList.add("fa", "fa-" + this.config.icons[this.messages[i].type]);
		} else {
			icon.classList.add("fa", "fa-question");
		}
		if(this.config.types.hasOwnProperty(this.messages[i].type)){
			icon.classList.add(this.config.types[this.messages[i].type]);
		}
		iconCell.appendChild(icon);
		callWrapper.appendChild(iconCell);
