The new plugin version using closure compiler seems to compile in ECMASCRIPT6_STRICT, which means that a 'use strict;' command is prepended to the minified JS files. This command makes my complete JavaScript code not work anymore. (I don't know why though, because the console does not throw any error.)
I think the strict mode should either be disabled, or the user should be enabled to configure the parameters for closure compiler by himself.

I hit a snag installing the plugin in NB9 because it complains about the Progress API (>=1.50.1 but only found 1.49.1) and Utility API versions (>= 9.11.1 but only found 9.9.1).

What steps will reproduce the problem?

   1.create style.css 
   2.minify it in separate file (it's immediately sync with remote server)
   3.change style.css, minify it again
   4.minified files changed byt not synchronized to remote server


What is the expected output? What do you see instead?

   Minified file must cause sync of itself

Hi
It doesn´t support back-tick symbol ( ) it is used in string template javascript, my minify-compress process fail and .min get blank.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals

Thanks

Hi guys,
thanks for a great netbeans plugin.

Is there a way to control file permissions of the generated minified files?

with regards from germany
Ariane

When I have object with variable named 'short', minified file is empty:
var test = {
variable: 'foo',
short: 'bar'
} // empty file.

var test = {
variable: 'foo',
// short: 'bar'
} // file OK.

What steps will reproduce the problem?
1. Create a JavaScript file like the following:

(function () {
   'use strict';

    var something = 1;

}());

2. Use this plugin to minify the JS file.
3. See that the minified JS file lacks 'use strict'.

What is the expected output? What do you see instead?

I would expect the minified file to still contain the 'use strict'; directive, 
rather than removing it (since it affects the functioning of the code).

What version of the product are you using? On what operating system?

I'm using version 2.2.1 of the "JS CSS Minify Compress" NetBeans plugin, with 
NetBeans version 8.0.2 on Windows 7.

Please provide any additional information below.

The problem is, I enabled the "Minify on save" because I used this in a project, but after using an other project, it minifies too but this is wrong from my expectation. Yes the feature has ONLY global options which is not good, because there are a lot of cases, where you use js css minify with this plugin in specific projects and in other cases you use a build tool like grunt or gulp or normal npm scripts. So please remove those things from the global options and add it to the project context to project properties. This make more sense. Maybe you can have it inside options too for defaults and override it from the project properties.

Regards

Chris

Could use some additional settings options for compression, for example, to 
kompresownay css file was not a single line, but each type elemnt class as a 
new line.

Hi. I use this plugin very active, but exclude HTML minify - it's impossible to use it without "copyright header" setting. In the rules HTML document must start with <!DOCTYPE html> tag, not from my header. But, if I keep this field empty, I have null text in start of document. Please, @Chris2011, correct this option - make it optioanally, or just make that empty field is not "null", but empty string (nothing).
It would be the best to check is there Doctype tag in the document, and if there is to put comment after it.
Thanks!

I use LESS wich generates a new CSS file everytime I hit save. It would be nice 
if minify would automaticly generate the minified CSS. Now I have to manualy do 
it before I see the results.

Love this plug-in

When I enable the option: "Create Separate Build Folder", the style_build folder, which is my new folder after minify a folder, contains all dev files, which should not. I have a style folder which has css files (for example) and the minified folder, should has only .min.css inside it and nothing more.

Cheers

Chris

When I enter something like // in the header field, it is reflected on the first line.

Might relate to #14

Great tool!

Is there a way to keep the semicolons when minify-ing a Javascript file?
It would be great to have a checkbox in the "JavaScript Minify" option tab.

Thanks 

Original issue reported on code.google.com by [email protected] on 10 Jul 2014 at 9:28

I know that it is possible to minify a folder with files inside, but it is not possible to minify multi selected files. Please add this feature. I only can minify one file. The minify action is deactivated when I right click on multi selected files.

Cheers

Chris

Thank you for making ES6 compression work! I have one question, it seems like the minifierbeans tab page in the Tools|Options menu (tested in Netbeans 10/11) is not being added. Am I doing something wrong? Compressing ES6 works perfectly. Also I'm wondering if an alternative user defineable target path for compressed files is provided in this new version, next to the default path.

For example

function resolveAfter2Seconds() {
  return new Promise(resolve => {
    setTimeout(() => {
      resolve('resolved');
    }, 2000);
  });
}

async function asyncCall() {
  console.log('calling');
  var result = await resolveAfter2Seconds();
  console.log(result);
  // expected output: 'resolved'
}

asyncCall();

In case, that the YUICompressor is old, not maintained anymore and can't handle modern CSS, we need to get rid of it and find another one. Most of them are NPM related so calling them from the commandline could be an option.

Special characters in strings are modified by v2.4.0. A line like
var a = "<div>anything</div>";
is converted to
var a="\x3cdiv\x3eanything\x3c/div\x3e";

Please leave character strings unchanged!

ver 2.5.1:

Hello. Now i have multiple rows when minify js. HOw i can render in one single line?

What steps will reproduce the problem?
1. CSS with // Comments
2. Right Click and Minimize CSS
3. Output has anything after comment commented out

What is the expected output? What do you see instead?
Expected to remove comments and leave only minimized code.
Comments are left and comment out remaining code.

What version of the product are you using? On what operating system?
 2.0 in Netbeans 8.0 on Windows 8.1

Please provide any additional information below.
I know I could simply use /* Comment */ but my CSS is heavily commented and it 
could be more efficient if it removed comments completely 

Original issue reported on code.google.com by [email protected] on 11 Aug 2014 at 5:04

What steps will reproduce the problem?
1. The minified file (JS/CSS) has a blank line and then minified code on 2nd

What steps will reproduce the problem?
1. Create project with Windows-1252 encoding
2. Write on a js file a string constant with special characters 
3. Minify it

What is the expected output? What do you see instead?
The resulting file is encoded on UTF8 and the special characters converted to 
garbage.

What version of the product are you using? On what operating system?
2.0 on Netbeans 8.0.2. Windows 7 64 bits

Please provide any additional information below.
Looks like the plugin disregards the project encoding and treats everything as 
UTF8 files

In case that this plugin will/can minify JS/CSS/HTML and JSON we should get rid of finding Java wrapper for that and using Node and NPM packages. For Node we have a huge amount of modern and maintained libs for minify JS (UglifyJS, Google Closure Compiler, etc.) CSS (CSS Nano, etc.), HTML (HTML Minifier, etc.) and JSON (TBD). So it makes much more sense to change the options to add the CLIs for those packages as we have it for NPM, Bower, Sass, Less, Grunt, Gulp, etc. We will be more flexible and we will get more updates.

• Switch from Java and YUICompressor to NPM and CSSNano.

• Switch from Java and Closure Compiler to NPM and Google Closure Compiler.

• Switch from Java and HTMLCompressor to NPM and html-minifier-terser.

• Switch from Java and XMLCompressor to NPM and minify-xml.

• Switch from Java and YUICompressor to NPM and CSSNano for minifing files in folders.

• Switch from Java and Closure Compiler to NPM and Google Closure Compiler for minifing files in folders.

• Switch from Java and HTMLCompressor to NPM and html-minifier-terser for minifing files in folders.

• Switch from Java and XMLCompressor to NPM and minify-xml for minifing files in folders.

• Switch from Java and YUICompressor to NPM and CSSNano for copy minified selected code.

• Switch from Java and Closure Compiler to NPM and Google Closure Compiler for copy minified selected code.

• Switch from Java and HTMLCompressor to NPM and html-minifier-terser for copy minified selected code.

• Switch from Java and XMLCompressor to NPM and minify-xml for copy minified selected code.

I'm attemping to minify my jquery script that is working flawlessly. It contains no errors and is based on the jquery plugin boilerplate. When clicking "Minify JS", I get a success message but the min.js file is empty. I have a notification about an exception from the plugin:

Netbeans 8.2 has been released but your awesome plugin isn't available for this version. I've manually installed it with the version for Netbeans 8.1 and it seems to work pretty good, no crashes or other problems so far.
Could you please add a version for Netbeans 8.2 on the plugin portal?

Installed tested then Uninstalled but now IDE is failing to load

I moved from Netbeans 8.2 to Netbeans 11.1, installed the Plugin, but the "JS CSS Minify Compress" option is missing in Preferences-Screen.

And somehow the Plugin is now just called "user installed plugins"

Minifying per se is working!

With javascript source files of more than 130 kb, the output (minifyed file) is empty.

I only can enable/disable the option, but it would be nice to customize the name of the new folder, which will be generated.

Cheers

Chris

When minifying JS, the minification process sometimes results in syntax errors due to questionable JS syntax/code. This is understandable. What is annoying is the minifier doesn't state what code caused errors, just that errors were encountered.

It'd be useful if for each error, there would be a message stating what line and char (approximately) in the original file contained the error, so that it can be rectified and minification rerun.

After call the minifier action on a specific file, I got the result of how much I saved as a JDIalog. This is annoying, beacuse you need to click ok. It would be better to get this as an notification, no disturbing and only a hint. If you need more information, I can click on it and read it.

I have a JS file which cannot be minified. The .min.js output is an empty file. Additionally Netbeans 8.2 outputs this exception:

org.mozilla.javascript.EvaluatorException: Compilation produced 4 syntax errors.

The JS file is valid and free of errors. I have been able to minify it with other tools:

$(function () {

//        ...
    function f(x, y=false) {
        // ...
    }

//        ...
});

If I remove the "= false" part it minifies successfully.

Hi, could you please explain how we can add this to the project build setting? I don't want to be manually minifying the files by choosing the option, mini web content on a folder before building the project.

Labels in options are too small for text on OS X.

It would be nice, to have an option to combine/concat js, css and maybe html and json files to one while minification. I don't know how is it working because of the order of some files but maybe with a separate meta file which contains the order or smth like that I don't know. I will not put it into the files itselfs, but it could be an option too.

Cheers

Chris

he don't know the .json extension.

Hi, when i minified a HTML file with latin character (á é) the output is wrong:
Facturación -> Facturaci�n

Hey,

many thanks to you for your tool, but i need bundling js/css files.

Is that possible to bundling minified files? eg. with an instruction comment 
like that:

+++++++++++ bundles.js ++++++++
#import ./../myJSFiles/file1.js
#import ./../myJSFiles/file2.js

function fooBar()
{
    alert("very nice");
}
+++++++++++++++++++++++++++++++

We have to get rid of the deprecated YUI Compressor and want to use a modern one. For this I have decided to use Closure Compiler.

I don't know, whether I need to add all node_modules to the externs, otherwise it will rename everything.

Hi guys, can you please upload this for NetBeans 8.1?

Hello Chris,

I'm trying to figure out the Maven coordinates for the binary JAR dependencies you have in release/modules/ext:

• code-minify.jar is com.yahoo.platform.yui:yuicompressor:2.4.7
• gson-2.2.3.jar could be com.google.code.gson:gson:2.2.3 although the binary is different
• html-minify.jar looks like com.googlecode.htmlcompressor:htmlcompressor although not sure which version?
• image-compressor.jar looks like com.github.depsypher:pngtastic although not sure which version?

I see that these JARs have their own dependencies which are not included. For example code-minify needs Rhino: I assume you either don't need it or you are using the Rhino from NetBeans?

If there is an ES6 class in javascript file. It isn't minified. The plugin just creates an empty file.

Example code:

class Polygon {
  // ..and an (optional) custom class constructor. If one is
  // not supplied, a default constructor is used instead:
  // constructor() { }
  constructor(height, width) {
    this.name = 'Polygon';
    this.height = height;
    this.width = width;
  }

  // Simple class instance methods using short-hand method
  // declaration
  sayName() {
    ChromeSamples.log('Hi, I am a ', this.name + '.');
  }

  sayHistory() {
    ChromeSamples.log('"Polygon" is derived from the Greek polus (many) ' +
      'and gonia (angle).');
  }

  // We will look at static and subclassed methods shortly
}

Output:

Empty file.

After a file is saved, plugin creates a minified file. If we edit and save the minified file, it creates a new file that has extension such .min.min...

The problem is, that all options are global for all projects. It would be better, to customize each option for HTML, JS, CSS, JSON, minify for each project. Because I have different project with different structure, languages, etc. As the Preprocessor functionality in NetBeans for SASS, for each project, you have the option to set the input and output folder. And here it would be nice to customize the options for each project and not globally.

Cheers

Chris

The plugin allows to save additional header information which will then be added to the minified file. But it is not possible to delete a previously saved text. If the field's content is removed and NetBeans is restarted, the previously saved text will still be there. (Counts for all file types - JS, CSS, HTML, XML, JSON)

(Tested with NetBeans 11.)

Hello,
Thank you for this great tool.
I am using v 2.2.1 in Netbeans 8.
It seems that css calc() spaces are removed, which breaks the instruction.
ex: calc(1vw + 10px) =>minify=> calc(1vw+10px)
Is there anything I can do to prevent that ?
Olivier

What steps will reproduce the problem?
1. Uncheck "Create New HTML File" in HTML Minify settings
2. Minify Web Content, or individual HTML file

What is the expected output? What do you see instead?
Whether the file is in same project folder or in a new created separate build 
folder, the HTML file is empty. That sure is minified! When "Create New HTML 
File" is checked, it minifies the new file as expected.

What version of the product are you using? On what operating system?
2.2.1 on Netbeans 8.0.2, Windows 7 Professional 64-bit
