Is there an offline version of JSLint for Windows?

Question

I would like to check my JavaScript files without going to JSLint web site.
Is there a desktop version of this tool for Windows?

From http://www.jslint.com/lint.html:

The analysis is done by a script running on your machine. Your script is not sent over the network.

It is also available as a Konfabulator widget. You can check a file by dragging it and dropping it on the widget. You can recheck the file by double-clicking the widget.

It is also available in a WSH Command Line version.

It is also available in a Rhino Command Line version.

Or since JSLint is a JavaScript program running in your browser - you could grab the script and run it locally.

@Michael S. Scherotter - Crockford abandoned the WSH command-line version, and 404'd the existing URLs! But there's a project with a version that works: http://code.google.com/p/jslint-for-wsh/ . If you prefet jshint, there's a similarly-modified version of jshint there, too. And also a csslint for WSH. – Cheeso Oct 23 '11 at 15:28
I took the liberty to replace the dead link wsh-link with the latest archived version (dec 2009) – GitaarLAB Aug 28 '13 at 09:34
This information is outdated. Since months, WSH is not supported anymore. Furthermore the link to the Konfabulator widget is dead. I just added [two possible solutions](http://stackoverflow.com/a/18792902/282729). – feklee Sep 15 '13 at 15:58

You can also use JavaScript Lint on your machine,
get it from here
JavaScript Lint

There are instructions on how to integrate it into many editors/IDE's on the above site. I use it in UltraEdit and it works great.

From the above site

You can run JavaScript Lint several ways:

You can integrate it into your IDE, such as Visual Studio, SciTE, or any other IDE supporting external tools. When JavaScript Lint finds an error, your IDE takes you directly to the line containing the error.

You can run it through Windows Explorer, which Windows programmers may prefer.

You can use the command line to integrate into your build system, or maybe you're a Linux programmer and simply prefer the command line!

Addendum to this old question: The WScript version of jslint.js produces error messages that are very much unlike error messages from any compiler.

If you want them to be similar, and if you want to be able to specify the name of the .js file in the command line, rather than using stdin to read the file, do this:

Download jslint.js, the WScript version.

Edit the jslint.js file. Scroll to the bottom and find this:

 (function(){if(!JSLINT(WScript.StdIn.ReadAll(),.....

Replace that (and everything that follows) with this:

(function(){
    var filename = "stdin";
    var content= "";
    if (WScript.Arguments.length > 0){
        filename = WScript.Arguments(0);
        var fso = new ActiveXObject("Scripting.FileSystemObject");
        //var file = fso.GetFile(filename);
        var fs = fso.OpenTextFile(filename, 1);
        content = fs.ReadAll();
        fs.Close();
        fso = null;
        fs = null;
    } else {
        content = WScript.StdIn.ReadAll();
    }
    if(!JSLINT(content,{passfail:false})){
        WScript.StdErr.WriteLine("JSLINT");
        for (var i=0; i<JSLINT.errors.length; i++) {
            // sample error msg:
            //  sprintf.js(53,42) JSLINT: Use the array literal notation [].
            var e=JSLINT.errors[i];
            if (e !== null){
                var line = (typeof e.line == "undefined")?'0':e.line;
                WScript.StdErr.WriteLine(filename + '(' +line+','+e.character+') JSLINT: '+e.reason);
                WScript.StdErr.WriteLine('    ' + (e.evidence||'').replace(/^\s*(\S*(\s+\S+)*)\s*$/,"$1"));
            }
        }}}());

This change does two things:

allows you to specify the file to run lint on, on the command line, rather than as stdin. Stdin still works if no file is specified at all.
emits the error messages in a format that is more similar to most C/C++ compilers.

Then, in a cmd.exe prompt, you can do:

cscript.exe  jslint.js   MyJavascriptModule.js

and you will get error messages like so:

JSLINT
MyJavascriptModule.js(7,17) JSLINT: 'xml' is already defined.
    var xml = new ActiveXObject("Microsoft.XMLHTTP");
MyJavascriptModule.js(10,5) JSLINT: 'xml' used out of scope.
    xml.open("GET", url, true);
MyJavascriptModule.js(11,9) JSLINT: 'xml' used out of scope.
    if (xml.overrideMimeType) {
MyJavascriptModule.js(12,9) JSLINT: 'xml' used out of scope.
    xml.overrideMimeType('text/plain; charset=x-user-defined');
MyJavascriptModule.js(14,9) JSLINT: 'xml' used out of scope.
    xml.setRequestHeader('Accept-Charset', 'x-user-defined');
MyJavascriptModule.js(17,5) JSLINT: 'xml' used out of scope.
    xml.onreadystatechange = function() {
MyJavascriptModule.js(28,5) JSLINT: 'xml' used out of scope.
    xml.send('');
MyJavascriptModule.js(34,16) JSLINT: Expected '{' and instead saw 'url'.
    if (proxy) url = proxy + '?url=' + encodeURIComponent(url);
MyJavascriptModule.js(51,16) JSLINT: Expected '{' and instead saw 'url'.
    if (proxy) url = proxy + '?url=' + encodeURIComponent(url);

I know this is an old one, but nobody's mentioned that JSLint is open source and available on github. https://github.com/douglascrockford/JSLint

You can use the HTML page that's included, or create your own interface using:

var options = {
    browser : true,
    plusplus : true,
    unparam : true,
    maxlen : 120,
    indent : 4 // etc
};
if (JSLINT(myCode, options)) {
    document.write('Passed!');
} else {
    document.write('Failed! :(');
}
document.write('<ul>');
for (i = 0; i < JSLINT.errors.length; i++) {
    document.write('<li><b>' + JSLINT.errors[i].line + ':</b> ' + JSLINT.errors[i].reason + '</li>');
}
document.write('</ul>');

And the only file "missing" (the readme says as much, but doesn't link to the compounded file he has) is currently here: http://jslint.com/web_jslint.js — ruffin, May 01 '12 at 15:23

We've found JSLint4Java very good. If you're using Ant to build your project then the Ant task it provides is particularly useful.

If you use notepad++, there's a JSLint plugin for you.

JSLint Plugin for Notepad++

You can find it and install from notepad++'s Plugin Manager.

Just save the html page to your hard drive, and then download the .js files it uses to the same location. That's the beauty of JavaScript.

You can integrate the tool this guy has made into Visual Studio.

A Visual Studio addin can be found here.

It is a bit rough but gets the job done.

I have just joined the project and will be bringing it up to date in the next few months.

JSLint Reporter running with Node.js

Easy to keep up to date.

Install Node.js.
Install jslint-reporter into: C:\jslint-reporter

Download JSLint:

C:\jslint-reporter>node wrapper.js --upgrade

Test:

C:\Temp>node C:\jslint-reporter\wrapper.js missing_semicolon.js
missing_semicolon.js:1:10:Expected ';' and instead saw 'console'.
missing_semicolon.js:2:1:'console' was used before it was defined.

JSLint Node.js package

Easy to set up, but you rely on the package author for keeping the included JSLint up to date:

Install Node.js.
Using npm, the package manager of Node.js, install JSLint:
```
C:\>npm -g install jslint
```

Test:

C:\Temp>jslint missing_semicolon.js

missing_semicolon.js
 #1 Expected ';' and instead saw 'console'.
    var x = 5 // Line 1, Pos 10
