JSLint′ A fork with some bad parts

• Download current version (2010-11-21)
• Source on GitHub

One of the few tools that I consider truly indispensable when developing websites is JSLint. Too bad it’s almost impossible to contribute back to the project, and that the project’s run by someone who “will hurt your feelings.”

Instead of complaining too much, I forked the official project and started adding in some bugfixes and additions that I find useful (which generally seem to focus on the CSS parser). Periodically, I merge the current trunk into my branch in the hopes that Crockford might, someday, do the reverse. We’ll see.

Tests

Each change that I make to Crockford’s official JSLint is backed up with QUnit tests. You’ll find them in the /test directory of the project.

JSLint Utils

If you use JSLint Utils, I’d recommend hopping into the project’s lib/vendor directory, and running make fork. That’ll drop the official JSLint, and bring you up to date with the latest version of JSLint′. It’s awesome.

Changelog

• 2010-11-21 (Based on JSLint from 2010-11-21):

  JSLint has an official GitHub presence! Excellent! I’ve reworked this repository entirely so that it’s based on the official repository, which means that the mirror branch has been dropped entirely, and that all the SHA1 IDs have changed. If you’ve forked this repository, or stored it locally for any reason at all, you’ll run into problems. Please reclone and start over.

  It’s inconvenient, I know, but this will make it much simpler to keep in step with changes in the official repo.

• 2010-10-06 (Based on JSLint from 2010-10-06):

  • Updating to the official 2010-10-06 release.

  • Backing out my url(...) fix in favour of the official fix in the aforementioned release.

• 2010-10-04 (Based on JSLint from 2010-10-01):

  • Fixing a bug in yesterday’s fix for font shorthand syntax. The line-height doesn’t have to be specified. It can be inherited.

  • Fixing support for url(/path/to/image.jpg) in background shorthand syntax. The following should pass linting now, when the css option is set:

    div {
        background:	url(/path/to/image.jpg);
    }
    

    In the current JSLint trunk, it throws a JavaScript error. That’s bad.

• 2010-10-03 (Based on JSLint from 2010-10-01):

  • Updated to the official JSLint version from 2010-10-01.

  • Fixed simple font shorthand syntax. The following should pass linting now, when the css flag is set:

    p {
        font: 12px/1 Helvetica;
    }
    

    In trunk, it throws an error when it hits the /, which cascades into errors for the line-height and font-family.

  • Added last-child as an acceptable pseudoclass. The following should pass linting now, when the CSS flag is set:

    p:last-child {}
    

    In trunk, it throws an error, claiming that last-child isn’t a pseudoclass.

• 2010-09-11 (Based on JSLint from 2010-09-08):

  • Updated to version of JSLint from 2010-09-08.

  • Adding an args option to support the arguments.callee and arguments.caller properties that I use quite often.

• 2010-05-16 (Based on JSLint from 2010-04-06):

  • Updated to version of JSLint from 2010-04-06

  • Added support for #RRGGBBAA style hex colours for alpha support via IE’s filter attribute. The following should pass linting now, when the css option is set:

    .myclass {
        filter:progid:DXImageTransform.Microsoft.Gradient(StartColorStr=#FFFFFF50,EndColorStr=#FFFFFF50);
    }
    

    In the current JSLint trunk, it throws a “Bad hex value” warning.

  • Added support for CSS3’s :: selector to designate pseudo-elements. The following should pass linting now, when the css option is set:

    .myclass::first-line {
        color:  red;
    }
    

    In the current JSLint trunk, it throws a “Expected pseudo, found ‘:first-line’ warning.

  • Added support for vendor-specific prefixes in pseudo-selectors. The following should pass linting now, when the css option is set:

    input::-moz-focus-inner {
        padding:  0;
    }
    

    This is especially important, given Gecko’s tendency to add 3px of padding to input elements that can only be removed via manipulation of input::-moz-focus-inner, but was rejected when submitted to the list.
