Per the [official documentation on file globbing][1], to watch for changes for files of a certain file type in the directory path and its subdirectories, you&#39;ll want:

    files: [&#39;js/**/*.js&#39;]

I am looking to create an effect [**like this**](http://jsfiddle.net/x4gSG/310/), but my website has a dynamic `background-color`. Note that this example uses a white overlay, which does not work with different backgrounds.

    p {
        width: 300px;
        overflow: hidden;
        height: 50px;
        line-height: 50px;
        position: relative;
    }
    p:after {
        content: &quot;&quot;;
        width: 100px;
        height: 50px;
        position: absolute;
        top: 0;
        right: 0;
        background: linear-gradient(90deg, rgba(255,255,255,0), rgba(255,255,255,1));
    }


What I was hoping to do was to set up a CSS opacity gradient. [**This**][2] sort of works, but the code is too messy. Looking at this second example, I could implement it in jQuery, but is there any way to do this entirely in CSS?

Is there some mechanism by which I can transform the comments that roxygen sees, preferably before it does the roxygen-&gt;rd conversion?

For example, suppose I have:

    #&#39; My function. Does stuff with numbers.
    #&#39;
    #&#39; This takes an input `x` and does something with it.
    #&#39; @param x a number.
    myFunction &lt;- function (x) {
    }

Now, suppose I want to do some conversion of the comment before roxygen parses it, for example replacing all instances of things in backticks with `\code{}`. Ie:

    preprocess &lt;- function (txt) {
        gsub(&#39;`([^ ]+)`&#39;, &#39;\\\\code{\\1}&#39;, txt)
    }
    # cat(preprocess(&#39;Takes an input `x` and does something with it&#39;.))
    # Takes an input \code{x} and does something with it.

Can I feed `preprocess` into roxygen somehow so that it will run it on the doclets before (or after would work in this case) roxygen does its document generation?

I don&#39;t want to do a permanent find-replace in my `.r` files. As you might guess from my example, I&#39;m aiming towards some rudimentary markdown support in my roxygen comments, and hence wish to keep my `.r` files as-is to preserve readability (and insert the `\code{..}` stuff programmatically).

Should I just write my own version of `roxygenise` that runs `preprocess` on all detected roxygen-style comments in my files, saves them temporarily somewhere, and then runs the *actual* `roxygenise` on those?

My codes folders and files like this, you never know how many sub folders in it:

    js/sub1/a.js
    js/sub2/b.js
    js/sub3/sub31/c.js
    js/sub4/sub41/sub411/d.js

Here is part of the Gruntfile.js:

    grunt.initConfig({
        watch: {
            src: {
                files: [&#39;js/*.js&#39;],
                tasks: []
            }
        }
    });


Grunt can&#39;t watch the changes of my all JavaScript files by using `&#39;js/*.js&#39;`. So how to write the correct file path expression?




How grunt watch files in sub folders?

My codes folders and files like this, you never know how many sub folders in it:
<pre><code class="hljs language-bash">js/sub1/a.js
js/sub2/b.js
js/sub3/sub31/c.js
js/sub4/sub41/sub411/d.js
</code></pre>
Here is part of the Gruntfile.js:

 watch: {
 src: {
 files: ['js/*.js'],
 tasks: []
 }
 }
});

Grunt can't watch the changes of my all JavaScript files by using <code>'js/*.js'</code>. So how to write the correct file path expression?

I have a simple route defined with `express.js`:

    exports.save = function (request, response)
    {
        var file = request.body.file;
        var content = request.body.content;
    
        var saved = false;
    
        if (fs.existsSync( file ))
        {
            saved = fs.writeFileSync(file, content, &#39;utf8&#39;);
        }

        console.log( saved ); // undefined or false, never true
    
        response.send(saved ? 200 : 500, saved ? &#39;saved&#39; : &#39;error&#39;); // 500, error
    };

Is `if (typeof saved === &#39;undefined&#39;) saved = true;` the only option? Feels hacky.

I am trying to add a feature of csv download option in my website. It should convert the html table present in the website in to csv content and make it downloadable. Ive been searching through internet for a good plugin and found some usefule ones like [http://www.dev-skills.com/export-html-table-to-csv-file/][1]  But it uses php script to do the download part. I was wondering if there is a pure javascript library available to do this feature using server side softwares like node.js without the use of php??

I need to disable a DIV and all it&#39;s content using Javascript.  I can swear that doing a simple 

    &lt;div disabled=&quot;true&quot;&gt; 

was working for me before, but for some reason it no longer works.  I don&#39;t understand why.

In IE10: the text &quot;Click Me&quot; is not greyed out and click handler still works.


I actually need this working for IE10.  Below is my code.

    &lt;html&gt;
        &lt;script&gt;
             function disableTest(){

                document.getElementById(&quot;test&quot;).disabled = true;
                var nodes = document.getElementById(&quot;test&quot;).getElementsByTagName(&#39;*&#39;);
                for(var i = 0; i &lt; nodes.length; i++){
                    nodes[i].disabled = true;
                }

             }


         &lt;/script&gt;

    &lt;body onload=&quot;disableTest();&quot;&gt;
       &lt;div id=&quot;test&quot;&gt;
           &lt;div onclick=&quot;alert(&#39;hello&#39;);&quot;&gt;

Hi I&#39;m trying to install Grunt on Windows 7 64 bit. I have installed Grunt using commands

     npm install -g grunt
     npm install -g grunt-cli

but now if I try to do `grunt init`, it is throwing me an error - 

&gt; A valid Gruntfile could not be found. Please see the getting started
&gt; guide for more information on how to configure grunt:
&gt; http://gruntjs.com/getting-started Fatal error: Unable to find
&gt; Gruntfile.

But when I look inside the grunt folder on my system the `Gruntfile.js` is there. can someone please guide me how to install this grunt properly and how to write built Script using the grunt. I have one HTML page and java script if i wants built a script using Grunt how can i do it?

I&#39;m trying to use [grunt-contrib-livereload](https://github.com/gruntjs/grunt-contrib-livereload), but can&#39;t seem to figure it out. [The readme](https://github.com/gruntjs/grunt-contrib-connect/blob/master/README.md) seems to skip over everything that I need explained, and then ends with an example that doesn&#39;t work when I try it and doesn&#39;t seem directly related to the documentation. I have searched for a better explanation in a blog post or tutorial or whatever, but haven&#39;t been able to find one. Can someone please explain how to get started with this tool?

Here are the kinds of questions I have, based on [the readme](https://github.com/gruntjs/grunt-contrib-connect/blob/master/README.md):

The documentation says the livereload task &quot;must be passed the list of files that have changed&quot; --- but how do I pass it this list of files? The example does not seem to illustrate this. Does regarde pass the list?

Is grunt-contrib-connect required? What does it do, and how do I use it? Do I need to learn connect before I try using livereload?

The readme mentions middleware that &quot;must be the first one inserted&quot; --- but inserted into what, before what else? And how is it inserted?

And I suppose I don&#39;t understand how I need to manipulate ports. &quot;All the browsers listening on the livereload port will be reloaded&quot; --- but how do I know which browser is listening to which port? Do I need to learn all about ports before I can try using livereload? (Any suggestion on how to best learn about that?)

Finally, in the example, there is a `folderMount` function that doesn&#39;t seem related to any of the documentation before. What is that, and do I need it?

I guess I&#39;m asking if someone can please:

- point me towards a tutorial that is much more effective than the current readme;
- explain these unexplained parts of the readme, if those answers are what I need to understand the plugin;
- or provide a functional example with some explanation of why it is functional.

I&#39;m new to Grunt. I&#39;m trying to configure Grunt on my Mac OSX Lion. 

I followed the instructions [here][1] and then created a project folder that contains the files below. When I try to run by typing &quot;grunt&quot; into terminal I get `command not found`. I&#39;ve also modified my paths `sudo nano /etc/paths` in the hope that adding the path would make the task runner work but it&#39;s still not working. Can someone assist with this please?

 1. Here is the README and examples: https://github.com/gruntjs/grunt-contrib-copy/blob/master/README.md.
 2. Here is the relevant part of the code (that I apparently cannot understand) from https://github.com/gruntjs/grunt-contrib-copy/blob/master/tasks/copy.js:

&lt;pre&gt;
module.exports = function(grunt) {
  &#39;use strict&#39;;

  var path = require(&#39;path&#39;);

  grunt.registerMultiTask(&#39;copy&#39;, &#39;Copy files.&#39;, function() {
    var kindOf = grunt.util.kindOf;

    var options = this.options({
      processContent: false,
      processContentExclude: []
    });

    var copyOptions = {
      process: options.processContent,
      noProcess: options.processContentExclude
    };

    grunt.verbose.writeflags(options, &#39;Options&#39;);

    var dest;
    var isExpandedPair;
    var tally = {
      dirs: 0,
      files: 0
    };

    this.files.forEach(function(filePair) {
      isExpandedPair = filePair.orig.expand || false;

      filePair.src.forEach(function(src) {
        if (detectDestType(filePair.dest) === &#39;directory&#39;) {
          dest = (isExpandedPair) ? filePair.dest : unixifyPath(path.join(filePair.dest, src));
        } else {
          dest = filePair.dest;
        }

        if (grunt.file.isDir(src)) {
          grunt.verbose.writeln(&#39;Creating &#39; + dest.cyan);
          grunt.file.mkdir(dest);
          tally.dirs++;

          grunt.verbose.writeln(&#39;Copying &#39; + src.cyan + &#39; -&gt; &#39; + dest.cyan);
          grunt.file.copy(src, dest, copyOptions);
          tally.files++;
        }
      });
    });
