The _coffee-script_ module registers its extension once required.

    $ echo &#39;console.log &quot;works&quot;&#39; &gt; module.coffee
    
    $ echo &#39;
    &gt; require(&quot;coffee-script&quot;)
    &gt; require(&quot;./module&quot;)
    &gt; &#39; &gt; test.js
    
    $ node test.js
    works

    $ node
    &gt; require(&#39;coffee-script&#39;); require(&#39;./module&#39;)
    works
    {}

**Edit**: This behaviour has changed with the relase of CoffeeScript 1.7.0. Now you need to do:

    require(&#39;coffee-script/register&#39;);

A more versatile solution would be to use [better-require](https://github.com/olalonde/better-require).

    npm install better-require

It lets you `require()` CoffeeScript files, no pre-compilation needed. (It also lets you `require()` a bunch of other file formats: CoffeeScript, clojurescript, yaml, xml, etc.) 

In the case of CoffeeScript, it simply requires the `coffee-script` module.

    require(&#39;better-require&#39;)();
    var myModule = require(&#39;./mymodule.coffee&#39;);
    var clojurescriptModule = require(&#39;./mymodule.cljs&#39;);
    // etc.


**Disclosure:** I wrote `better-require`.

I have been using int(10) and just noticed that Wordpress uses bigint(20) - What is different to use bigint(20) and int(10) for id auto increment? Which one should I use for id column?

    `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,

Vs
    
    `id` int(10) unsigned NOT NULL AUTO_INCREMENT,

Thanks.

My source files are located under src and my test files are located under tests. When I want to run a test file, say python myTest.py, I get an import error: &quot;No module named ASourceModule.py&quot;.

How do I import all the modules from source needed to run my tests?

I&#39;m using Node.js and wanting to incorporate CoffeeScript into my workflow. I have two use-cases:

 1. I want to be able to write JavaScript files which `require()` CoffeeScript modules
 2. I want to be able to load CoffeeScript modules from within the node REPL

**For case #1:** I can just compile from `.coffee` to `.js` and `require()` the `.js` module, as a workaround. 

**For case #2:** Right now I&#39;m `eval()`ing the output of `coffee-script.compile()`.

Is there a better, more unified way to do this?

I&#39;m using the scrollTo jQuery plugin and would like to know if it is somehow possible to temporarily disable scrolling on the window element through Javascript? The reason I&#39;d like to disable scrolling is that when you scroll while scrollTo is animating, it gets really ugly ;)

Of course, I could do a `$(&quot;body&quot;).css(&quot;overflow&quot;, &quot;hidden&quot;);` and then put it back to auto when the animation stops, but it would be better if the scrollbar was still visible but inactive.

How to disable scrolling temporarily?

I&#39;ve just begun to work with Require.JS and I&#39;m a bit unclear on the appropriate cases in which it should be used, as well as the correct way to use it in those cases.

Here&#39;s how I currently have things set up with Require.JS. I have two functions, `functionA()` and `functionB()`. Both of these functions require an additional function, `functionC()` to work properly.

I only want to load functionC() when necessary, i.e. when functionA() or functionB() is going to be called. So I have the following files:

**functionC.js**

    functionC(){
      //do stuff
    }

**functionA.js**

    functionA(){  
      define([&#39;functionC&#39;],function(){
        //functionC() is loaded because it is listed as a dependency, so we can proceed
        //do some functionA() stuff
      });
    }

**functionB.js**

    functionB(){  
      define([&#39;functionC&#39;],function(){
        //functionC() is loaded because it is listed as a dependency, so we can proceed
        //do some functionB() stuff
      });
    }

So, is this set up correctly? And if I end up calling both functionA() and functionB() on the same page, is extra work being done since they both load the functionC.js file? If so, is that a problem? And if so, is there a way to set it up so that they first check to see if functionC.js has been loaded yet, and only load it if it hasn&#39;t been? Finally, is this an appropriate use of Require.JS?

I have a string for a title and a string for a link.  I&#39;m not sure how to put the two together to create a link on a page using Javascript.  Any help is appreciated.

EDIT1: Adding more detail to the question.
The reason I&#39;m trying to figure this out is because I have an RSS feed and have a list of titles ands URLs.  I would like to link the titles to the URL to make the page useful.

EDIT2: I am using jQuery but am completely new to it and wasn&#39;t aware it could help in this situation.

How do I create a link using javascript?

I&#39;m using the below code to try to trim the string in Javascript but am getting the error mentioned in the title:

    function trim(str) {
        return str.replace(/^\s+|\s+$/g,&#39;&#39;);
    }


**Edit:**

I fixed the problem.... sorry I should have put the code on how I was calling it too.... realized I accidentally was passing the object of the form field itself rather than its value.


var.replace is not a function

I&#39;m trying to write a function that either accepts a list of strings, or a single string. If it&#39;s a string, then I want to convert it to an array with just the one item so I can loop over it without fear of an error.

So how do I check if the variable is an array?

I&#39;m trying to learn about new usages of javascript as a serverside language and as a functional language. Few days ago I heard about node.js and express framework. Then I saw about underscore.js as a set of utility functions. I saw [this question on stackoverflow
][1]. It says we can use underscore.js as a template engine. anybody know good tutorials about how to use underscore.js for templating, especially for biginners who have less experience with advanced javascript. Thanks

I connect to the linux server via putty SSH. I tried to run it as a background process like this:

    $ node server.js &amp;


However, after 2.5 hrs the terminal becomes inactive and the process dies.  Is there anyway I can keep the process alive even with the terminal disconnected?

---

**Edit 1**

Actually, I tried `nohup`, but as soon as I close the Putty SSH terminal or unplug my internet, the server process stops right away. 


Is there anything I have to do in Putty?

**Edit 2 (on Feb, 2012)**

There is a `node.js` module, [forever][1]. It will run node.js server as daemon service.

You often see example hello world code for Node that creates an Http Server, starts listening on a port, then followed by something along the lines of:

    console.log(&#39;Server is listening on port 8000&#39;);

But ideally you&#39;d want this instead:

    console.log(&#39;Server is listening on port &#39; + server.port);

How do I retrieve the port the server is currently listening on without storing the number in a variable prior to calling `server.listen()`?

I&#39;ve seen this done before but I can&#39;t find it in the Node documentation. Maybe it&#39;s something specific to express?

I love [Bundler][1], it&#39;s great at dependency management.  I love [npm][2], installing node packages is easy!  I have a nodejs app and would love to be **able to specify my apps dependencies and easily install / update them** wherever I deploy my app. This isn&#39;t a library I&#39;m releasing, it&#39;s a full fledged web-app.

I&#39;m aware of the `npm bundle` command, but that just seems to simply override the directory where packages are installed.

I&#39;m used to using bundler in this fashion:

    # Gemfile
    gem &quot;rails&quot;, &quot;3.0.3&quot;


Installs rails v3.0.3 and any other required gems on the host machine only if it doesn&#39;t already exist

    &gt; bundle install

**How can I achieve something similar with npm?**

There are many questions about this, not least:
  [jQuery version of array contains][1], [a solution with the splice method][2] and many more. However, they all seem complicated and annoying.

With the combined powers of javascript, jQuery and coffeescript, what is the very cleanest way to remove an element from a javascript array? We don&#39;t know the index in advance. In code:

    a = [4,8,2,3]
    a.remove(8)     # a is now [4,2,3]

Failing a good built-in method, what is a clean way of extending javascript arrays to support such a method? If it helps, I&#39;m really using arrays as sets. Solutions will ideally work nicely in coffeescript with jQuery support. Also, I couldn&#39;t care less about speed, but instead prioritize clear, simple code.

What&#39;s the best way to chain methods in CoffeeScript? For example, if I have this JavaScript how could I write it in CoffeeScript?

    var req = $.get(&#39;foo.htm&#39;)
      .success(function( response ){
        // do something
        // ...
      })
      .error(function(){
        // do something
        // ...
      });


Method chaining with function arguments

Reading through [this][1], I came to the bit on default values for function arguments:

    fill = (container, liquid = &quot;coffee&quot;) -&gt;
      &quot;Filling the #{container} with #{liquid}...&quot;

That&#39;s neat, but then I tried this:

    fill = (container=&quot;mug&quot;, liquid = &quot;coffee&quot;) -&gt;
      &quot;Filling the #{container} with #{liquid}...&quot;

    alert fill(liquid=&quot;juice&quot;)

and got the unexpected alert with `&quot;Filling the juice with coffee...&quot;`. So then I tried this:

    fill = (container=&quot;mug&quot;, liquid = &quot;coffee&quot;) -&gt;
      &quot;Filling the #{container} with #{liquid}...&quot;

    alert fill(null, &quot;juice&quot;)

and it worked. It&#39;s not pretty though. Is there a better way, or is this the idiomatic way to do this?

Coffeescript --- How to create a self-initiating anonymous function?

In CoffeeScript, the `while` loop comes standard:

    while x()
       y()

However, the following&lt;sup&gt;1&lt;/sup&gt; doesn&#39;t work:

    do
      y()
    while x()

And this is simply sugar for the first example:

    y() while x()

Does CoffeeScript come with a built-in loop that executes at least once?

&lt;sup&gt;1&lt;/sup&gt;As an aside, `do` *is* a keyword — it&#39;s used to call anonymous functions.
