About

This extension adds the ability to run any scripts loaded into the current page through Douglas Crockford’s JSLint implementation.

Installation/Usage/Hacking

Dependencies

There are no external dependencies for the extension itself, but building it requires ruby and rake.

Building

The rake build task will copy all the necessary files into a directory called output/.

Installation

After building, the extension can be installed as follows (as of Chrome version 10.0.612.1 dev):

1. From Chrome, click the tool menu button.
2. Click Tools -> Extensions.
3. Click the plus sign “+” next to “Developer Mode”. This step is not necessary if Developer Mode is already open.
4. Click the “Load Unpacked Extension” button.
5. Navigate to the output/ directory under the project checkout directory and click the “Open” button.

Usage

Installing the extension as described above will add a button next to the url bar in Chrome. Clicking that button will show a small popup with a drop down list of all the javascript files loaded in the current page. Choose the file to be examined in the list, and click the “JSLint” button. Results will be shown in the popup.

Hacking

The output/ directory is only for the built version of the extension. When editing files in the project, you’ll want to edit them in their respective source locations. All javascripts go in src/, all static content (images, html files, css files, the manifest, etc.) belongs in content/. When you’re ready to do a live test of your changes, simply rebuild and then reload the extension in Chrome using the steps outlined above.

All scripts in the project are covered 100% by unit tests, because the code was written test first. To run the tests, simply point Chrome to the url file:///path/to/project/location/jslint_chrome/test/unit/tests.html
