`gulp.watch` internally uses [`vinyl-fs`][1] (see [source][2]), which uses [`gaze`](https://github.com/shama/gaze), which uses itself [`minimatch`](https://github.com/isaacs/minimatch), so you should be able to ignore some files using `!./js/*.min.*`.

In fact, this is even described in [vinyl-fs&#39;s README][3]:

    fs.src([&quot;./js/**/*.js&quot;, &quot;!./js/vendor/*.js&quot;])

Faced the same issue in gulp 4, the fix is as follows

```js
gulp.task(&#39;watch&#39;, function() {
   gulp.watch([&#39;js/*.js&#39;,&#39;!js/*.min.js&#39;], css);
});
```

`css` is `gulp.series`/`gulp.parallel` or any function that you want to run.

I&#39;d like to be able to scan barcodes via a hand held scanner and handle the results with Javascript.

A barcode-scanner works almost like a keyboard. It outputs the scanned/translated (barcode-&gt;number) data raw (right?). Actually I just need to catch the output and proceed. But how?

Here&#39;s some pseudocode I&#39;d like to make work:

    $(document).on(&quot;scanButtonDown&quot;, &quot;document&quot;, function(e) {
        // get scanned content
        var scannedProductId = this.getScannedContent();
        
        // get product 
        var product = getProductById(scannedProductId);

        // add productname to list
        $(&quot;#product_list&quot;).append(&quot;&lt;li&gt;&quot; + product.name + &quot;&lt;/li&gt;&quot;);
    });


- Any ideas (frameworks, plugins, snippets)?
- Any barcode-scanner (hardware) recommendation?

Thanks in advance!

*I found [this][1] and [this][2] good questions but I&#39;d like to get more information about the handling. Just to focus a textarea may be not enough in my case.*

Javascript: How to read a hand held barcode scanner best?

I&#39;m developing a ColdFusion website using Aptana. We&#39;re using SVN for version control.

I renamed a few files and am now trying to commit one of them, but I&#39;m getting the following error:

    &#39;SVN Commit&#39; has encountered a problem.
    org.apache.subversion.javahl.ClientException: Illegal target for the requested operation
    svn: Commit failed (details follow):
    svn: Cannot commit &#39;R:\myPath\My-New-File-Name.cfm&#39; because it was moved from &#39;R:\myPath\My-Old-File-Name.cfm&#39; which is not part of the commit; both sides of the move must be committed together

This seems to indicate that I need to commit both the previous file (that was renamed) and the new renamed file together. How can I commit a file that no longer exists...?

Renamed file, now SVN not allowing me to commit?

I would like to watch all, but the .min.ext files in my directories with **gulp.js**. What is the best way to filter out those?

Example: 

    gulp.task(&#39;watch&#39;, function(e) {
       gulp.watch(&#39;./js/*.js&#39;, [&#39;css&#39;]); // don&#39;t want to watch .min.js files. what is best way?
    });

**EDIT:** If can&#39;t be done without external packages, which one is the most reputable?

Best way to filter files in gulp.watch?

I would like to watch all, but the .min.ext files in my directories with gulp.js. What is the best way to filter out those?
Example:
<pre><code class="hljs language-javascript">gulp.task('watch', function(e) {
 gulp.watch('./js/*.js', ['css']); // don't want to watch .min.js files. what is best way?
});
</code></pre>
EDIT: If can't be done without external packages, which one is the most reputable?

I am thinking about it and this is what I came up with:

Let&#39;s see this code below:

```js
console.clear();
console.log(&quot;a&quot;);
setTimeout(function(){console.log(&quot;b&quot;);},1000);
console.log(&quot;c&quot;);
setTimeout(function(){console.log(&quot;d&quot;);},0);
```
A request comes in, and JS engine starts executing the code above step by step. The first two calls are sync calls. But when it comes to `setTimeout` method, it becomes an async execution. But JS immediately returns from it and continue executing, which is called `Non-Blocking` or `Async`. And it continues working on other etc.

The results of this execution is the following:

&gt; a c d b

So basically the second `setTimeout` got finished first and its callback function gets executed earlier than the first one and that makes sense.

We are talking about single-threaded application here. JS Engine keeps executing this and unless it finishes the first request, it won&#39;t go to second one. But the good thing is that it won&#39;t wait for blocking operations like `setTimeout` to resolve so it will be faster because it accepts the new incoming requests.

But my questions arise around the following items:

**#1:** If we are talking about a single-threaded application, then what mechanism processes `setTimeouts` while the JS engine accepts more requests and executes them? How does the single thread continue working on other requests? What works on `setTimeout` while other requests keep coming in and get executed.

**#2:** If these `setTimeout` functions get executed behind the scenes while more requests are coming in and being executed, what carries out the async executions behind the scenes? What is this thing that we talk about called the `EventLoop`?

**#3:** But shouldn&#39;t the whole method be put in the `EventLoop` so that the whole thing gets executed and the callback method gets called? This is what I understand when talking about callback functions:

```js
function downloadFile(filePath, callback)
{
   blah.downloadFile(filePath);
   callback();
}
```
But in this case, how does the JS Engine know if it is an async function so that it can put the callback in the `EventLoop`? Perhaps something like the `async` keyword in C# or some sort of an attribute which indicates the method JS Engine will take on is an async method and should be treated accordingly.

**#4:** But an [article][1] says quite contrary to what I was guessing on how things might be working:

&gt; The Event Loop is a queue of callback functions. When an async
&gt; function executes, the callback function is pushed into the queue. The
&gt; JavaScript engine doesn&#39;t start processing the event loop until the
&gt; code after an async function has executed.

**#5:** And there is this image here which might be helpful but the first explanation in the image is saying exactly the same thing mentioned in question number 4:

![enter image description here][2]

So my question here is to get some clarifications about the items listed above?

I&#39;m not sure how to fix this and I have gotten this on two different npm module installs. I can install other modules however.

What I have tried:
Install whatever dependencies it needs. (ursa, node-gyp etc)
Install Visual C++ 2005.
Install Visual C++ 2010.
Change the enviroment variable path to /VC/ (found on another StackOverflow thread/question.
Googled, googled &amp; googled.

I also get an error trying do:

    npm install ursa

I&#39;m new to gulp and have been looking through example set-ups.
Some people have the following structure:

    gulp.task(&quot;XXXX&quot;, function() {
        gulp.src(&quot;....

Other people have this:

    gulp.task(&quot;XXXX&quot;, function() {
       return gulp.src(&quot;....

I&#39;m wondering what difference the **return** on the src makes??

`bower install` behind a proxy fails in timeout with the following settings (some set are useless...) :

I have also tried an install/uninstall of bower and a `bower clean cache`.

bower behind a proxy

This is a pretty dumb question, but I haven&#39;t really been able to find a satisfactory answer: How do I use gulp globbing to select *all* files in *all* subdirectories below a certain directory?

I&#39;ve tried:

`&#39;./src/less&#39;`
`&#39;./src/less/&#39;`
`&#39;./src/less/*&#39;`

None of them seem to work.

gulp globbing- how to watch everything below directory

In my gulp.js file I&#39;m streaming all HTML files from the `examples` folder into the `build` folder. 

To create the gulp task is not difficult:

    var gulp = require(&#39;gulp&#39;);
    
    gulp.task(&#39;examples&#39;, function() {
    	return gulp.src(&#39;./examples/*.html&#39;)
    		.pipe(gulp.dest(&#39;./build&#39;));
    });

But I can&#39;t figure out how retrieve the file names found (and processed) in the task, or I can&#39;t find the right plugin.

Get the current file name in gulp.src()

Here is a composed task I don&#39;t know how to replace it with task dependencies.

    ...

     var server = function(){
      gulp.run(&#39;jasmine&#39;);
      gulp.run(&#39;embed&#39;);
     };
     var client = function(){
      gulp.run(&#39;scripts&#39;);
      gulp.run(&#39;styles&#39;);
      gulp.run(&#39;copy&#39;);
      gulp.run(&#39;lint&#39;);
     };
     gulp.watch(&#39;app/*.js&#39;, server);
     gulp.watch(&#39;spec/nodejs/*.js&#39;, server);
     gulp.watch(&#39;app/backend/*.js&#39;, server);
     gulp.watch(&#39;src/admin/*.js&#39;, client);
     gulp.watch(&#39;src/admin/*.css&#39;, client);
     gulp.watch(&#39;src/geojson-index.json&#39;, function(){
      gulp.run(&#39;copygeojson&#39;);
     });
    });

        .pipe(source(&#39;app.js&#39;))
        .pipe(gulp.dest(&#39;./build&#39;))       // OK. app.js is saved.
        .pipe($.rename(&#39;app.min.js&#39;))
        .pipe($.streamify($.uglify())
        .pipe(gulp.dest(&#39;./build&#39;))       // Fail. app.min.js is not saved.
    );

Piping to multiple destinations when file.contents is a stream is not currently supported. What is a workaround for this problem?
