Delicious Extension

I made a delicious extension for my MediaWiki site. The extension lets you insert all of the stories with a given tag into the wiki. Note, I made the extension for my purposes; not general use. This means the extension has 2 downsides: right now it is hard coded to my username and the you have to edit a CSS file and add an image somewhere. These things can be easily modified by someone in the future. (If someone does modify the code, I would be glad to host/link to your modifications). Also, when you manually add the css to MediaWiki:Common.css you do not impact load times as much as if the CSS would be a separate file that the script calls.

The extension uses thumbnails from http://thumbshots.com. I am using the free server, so it only shows the homepage of the site. It's not very useful, but I think it adds some color to the list.

This extension is released under the Creative Commons BY license.

Installation

1. Save the Extension code as /extensions/Delicious.php
2. Save the Delicious logo to /extensions/delicious.20.gif
3. Copy the CSS code to MediaWiki:Common.css
4. Link to the Delicious Code in LocalSettings.php: include("/extensions/Delicious.php");

Use

• User is hardcoded in the script. Someone should make it multi user.

<delicious>tag</delicious>
