It is in that spirit that that Drupal for Firebug was developed as a way to extend the capabilities of Firebug by mixing in a little Drupal. Drupal for Firebug is both a FireFox Extension and a Drupal Module. To celebrate Drupalcon Szeged there are now releases for both Drupal 5 and Drupal 6 available. Get the extension and download the module, check our the test and demonstration site, and watch the drupal magic happen right in your Firebug window:
With a copy of the module and the Firefox extension installed, a developer can see debug messages, examine the SQL query log (with Devel module), look at how a Drupal page load is handling a site's users, views, nodes, and forms, and even execute PHP. The goal of the module and extension is to create a framework for centralizing Drupal development and debugging work using power of Firebug. The major features include:
- More centralization of web development debugging information by moving that information from Drupal page view into separate Firebug window. This helps to provide a clean separation of development debug information from the rest of the site.
- Clean and external debugging message text and dumpable PHPs arrays and objects which can be displayed in the Firebug debugging window using the handy firep() function where they can be viewed without disrupting the rest of the page flow. There is also a handy "debug message only" search feature which is helpful in locating specific pieces of information in the debugging output.
- Integration with the wonderful Devel module is available to provide a Firebug accessible SQL query log. Since the Firebug debugging window can be resized, hidden, or broken out as a separate window, it provides additional options (beyond appending the log to the bottom of the screen) for viewing the SQL query log.
- Complete information about each user and node and view and form that is accessed during a page load is available. This can be invaluable in determining what Drupal items are being referenced and what $op is being performed on them. There is awareness of the original and modified state of the view and form items and even smart color highlighting to tell you when additions, changes, or deletions have happened to the item during the hook_form_alter or hook_views callbacks.
This is only the initial release of the module and there are plenty of tweaks and improvements to make down the road. The real secret sauce will be figuring out what are the most useful pieces of information to display in the Firebug window and making some important XUL interface improvements to the Firefox Extension to increase usability around the viewing and sorting of debugging data. Think HTML browser style functionality for the User, Form, Node, and View arrays and objects. But for now, at least it speaks our language.
