I’ve made quite a few changes to my pluggable version of slurl.com, most of which centred around replacing the hash-slurl.js plugin with hash-fu.js. Below is a summary of the changes made today.

The Map

• Removed some CSS code left over from the original work done for Hack a Day 2009.
• Replaced hash-slurl.js with hash-fu.js.
• Removed the Gears plugin since that’s being phased out, with developers being encouraged to use HTML5 goodness.

UI Top Bar

Plugins for the UI top bar were altered so they’d report an error if the UI top bar plugin wasn’t loaded instead of throwing an exception to the JavaScript console.

The UI top bar plugin was tweaked so it could be hidden.

If the error reporting plugin is loaded, but UI top bar isn’t, the modal dialog pops up immediately instead of adding a notification to the UI top bar.

Implemented a feature request; When plugins with drop-down boxes are loaded into the top bar, they’re hidden until they’re populated with options.

A bug in the region search plugin was fixed (return false wasn’t getting passed from the search handler to the event handler).

Support for hash-fu.js was added to the third party services plugin. Example loading the New World Notes stories featuring SLURLs.

mapapi.js

No feature alterations here, just some fixes for a couple bugs that cropped up during the course of today’s updates, one of which was in the error handler and the other was to fix how axes with co-ordinates set to 0 were handled.

hash-fu.js

hash-fu.js isn’t too dissimilar to hash-slurl.js, in the respect that they both monitor document.location.hash for changes, then attempt to act upon those changes.

Where hash-slurl.js tried to cram the processing for such changes into the same file, hash-fu.js prefers to leave such logic to other plugins. Where hash-slurl.js uses an if-else structure with hard-coded feature support, hash-fu.js uses a for structure with callbacks. Additionally, it supports multiple commands being fired in the same fragment via a fake query string e.g. example.com/#?foo=bar&slurl/Ahern/.
