As written in the [comment documentation][1], you can either use `//` which will translate to a HTML comment or `//-` which won&#39;t be visible in the outputted HTML code.

  [1]: https://pugjs.org/language/comments.html

In jade we use **//-** for comment.
If you are trying to comment a block, make sure it should be indented properly like in below example-

    doctype html
    
    html(lang=&#39;en&#39;)
        body
            //- 
                This should be a comment
                Indent correctly for block content

How to restore my Local database to Windows Azure Database?

I&#39;ve seen this: https://stackoverflow.com/questions/3007190/vsts-2010-sgen-error-could-not-load-file-or-assembly-exception-from-hresult and none of the answers work. It also doesn&#39;t appear when I build or anything. I can run the project fine, it happens when I try to add an entity framework templated controller:



![controller settings][1]


Then I get this error:

![error message][2]

All project files are on my network share because that is where My Documents resides for our work. Here is what I tried:

1) Turning Generator Serialization Assembly in project settings to on, off, and auto.

2) Adding sgen.exe.config to C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools with the following code:

    &lt;configuration&gt;
     &lt;runtime&gt;
       &lt;loadFromRemoteSources enabled=&quot;true&quot; /&gt;
     &lt;/runtime&gt;
    &lt;/configuration&gt;
3) Tried to unblock the assemblies, but I had no unblock option in the properties tab.
![no unblock option][3]


**None of these solutions work**. Does anyone have any idea how I can fix this???
This error occurs for any custom assembly from nuget or my own projects due to their location existing on the network space, but only when trying to add an EF templated controller. I can build and run the program fine.

            / This should be a comment

Regarding node.js, I&#39;m using socket.io for real-time socket connection from the client application to the server application.
I just heard about engine.io, is engine.io a replacement for socket.io?
I could not find any useful information on engine.io website

Thanks in advance

What&#39;s the difference between engine.io and socket.io?

Is there a way to execute some code (in a file or from a string, doesn&#39;t really matter) before dropping into interactive mode in node.js?

For example, if I create a script `__preamble__.js` which contains:

    console.log(&quot;preamble executed! poor guy!&quot;);

and a user types `node __preamble__.js` they get this output:

    preamble executed! poor guy!
    &gt; [interactive mode]

I&#39;m having trouble with a variable (config) declared in a jade template file (index.jade) that isn&#39;t passed to a javascript file, which then makes my javascript crash. Here is the file (views/index.jade):

    h1 #{title}
    
    script(src=&#39;./socket.io/socket.io.js&#39;)
    script(type=&#39;text/javascript&#39;)
      var config = {};
      config.address = &#39;#{address}&#39;;
      config.port = &#39;#{port}&#39;;
    script(src=&#39;./javascripts/app.js&#39;)

Here is a part of my app.js (server side):

      app.use(express.bodyParser());
      app.use(express.methodOverride());
      app.use(app.router);
      app.use(express.static(__dirname + &#39;/public&#39;));
    });
    
    app.configure(&#39;development&#39;, function(){
      app.set(&#39;address&#39;, &#39;localhost&#39;);
      app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
    });
    
    app.configure(&#39;production&#39;, function(){
      app.use(express.errorHandler());
    });
    
    // Routes
    
    app.get(&#39;/&#39;, function(req, res){
      res.render(&#39;index&#39;, {
        address: app.settings.address,
        port: app.settings.port
    });
    });
    
    if (!module.parent) {
      app.listen(app.settings.port);
      console.log(&quot;Server listening on port %d&quot;,
    app.settings.port);
    }
    
    // Start my Socket.io app and pass in the socket
    require(&#39;./socketapp&#39;).start(io.listen(app));

And here is a part of my javascript file that crashes (public/javascripts/app.js):

    (function() {
            var socket = new io.Socket(config.address, {port: config.port, rememberTransport: false});

I&#39;m running the site on development mode (NODE_ENV=development) on localhost (my own machine). I&#39;m using node-inspector for debugging, which told me that the config variable is undefined in public/javascripts/app.js.

Any ideas?? Thanks!!

How to pass variable from jade template file to a script file?

I want to use a simple loop like `for(int i=0; i&lt;10; i++){}`.

How do I use it in the Jade engine? I&#39;m working with Node.js and use the expressjs framework.

Loop in Jade (currently known as &quot;Pug&quot;) template engine

**Note**: my auto answer at end of the post

I&#39;m trying to make a better experience of nodeJS and i don&#39;t really like to get all the script in one file.

so, following a post here i use this structure

    ./
     config/
       enviroment.js
       routes.js
     public/
       css/
         styles.css
       images
     views
       index
         index.jade
       section
         index.jade
       layout.jade
     app.js

    	});
    
    	//development configuration
    	app.configure(&#39;development&#39;, function() {
    		app.use(express.errorHandler({
    			dumpExceptions: true,
    			showStack: true
    		}));
    	});

    			h1 Content goes here

The error i get is:

But i don&#39;t really know what is the problem...

I&#39;m starting thinking is because the modules exports...



**Answer:**
Far away the unique solution i found is to change the place i defined app.set(&#39;views&#39;) and views engine

I moved it to the app.js and now is working well.


    var express = require(&#39;express&#39;);
    var app = module.exports = express.createServer();
    
    
    require(&#39;./config/enviroment.js&#39;)(app, express);
    
    app.set(&#39;views&#39;, __dirname + &#39;/views&#39;);
    app.set(&#39;view engine&#39;, &#39;jade&#39;);
    
    require(&#39;./config/routes.js&#39;)(app);
    
    app.listen(3000);

I don&#39;t really understand the logic behind this but i gonna supose it have one.

Error: Failed to lookup view in Express

Curious if I&#39;m doing this right and if not how you guys would approach this.

I have a Jade template that needs to render some data retrieved from a MongoDB database and I also need to have access to that data inside a client side JavaScript file.

I&#39;m using Express.js and sending the data to the Jade template as follows :

    var myMongoDbObject = {name : &#39;stephen&#39;};
    res.render(&#39;home&#39;, { locals: { data : myMongoDbObject } });

Then inside of **home.jade** I can do things like :

    p Hello #{data.name}!

Which writes out : 

    Hello stephen!

Now what I want is to also have access to this data object inside a client side JS file so I can manipulate the Object on say a button click before POSTing it back to the server to update the database.

I&#39;ve been able to accomplish this by saving the &quot;data&quot; object inside a hidden input field in the Jade template and then fetching the value of that field inside my client-side JS file.

**Inside home.jade**

    - local_data = JSON.stringify(data) // data coming in from Express.js
    input(type=&#39;hidden&#39;, value=local_data)#myLocalDataObj

Then in my client side JS file I can access local_data like so :

**Inside myLocalFile.js**

    var localObj = JSON.parse($(&quot;#myLocalDataObj&quot;).val());
    console.log(localObj.name);

However this stringify / parsing business feels messy. I know I can bind the values of my data object to DOM objects in my Jade template and then fetch those values using jQuery, but I&#39;d like to have access to the actual Object that is coming back from Express in my client side JS. 

Is my solution optimal, how would you guys accomplish this?

Accessing Express.js local variables in client side JavaScript

I like to put all my inline elements in a single line. 

    &lt;ul&gt;
      &lt;li&gt;&lt;a&gt;click&lt;span&gt;here&lt;/span&gt;&lt;strong&gt;!&lt;/strong&gt;&lt;/a&gt;&lt;/li&gt;

Wondering if there&#39;s a better way to create inline elements in Jade than this:

    ul
      li 
        a(href=&quot;#&quot;) click 
          span here
          strong !

This get&#39;s a little closer but I&#39;m not sure how to add the span and strong tags without breaking the lines.

    ul
      li: a(href=&#39;#&#39;) click
        span ...

This obviously isn&#39;t a super big problem but it&#39;s a little annoying that I can&#39;t put inline elements inline. Thanks for the help
