Holiday project: JMaki for Roller

Comments[0] 01:12PM Jan 02, 2008 by Dave in Java

Over the holidays I avoided doing anything directly related to my current set of work tasks. Sun went quiet, which helped, and I ignored the messages that piled-up in the Roller user and dev lists. It was so quiet that I had time for a fun little project: a JMaki plugin for Roller.

JMaki makes it easy to use JavaScript widgets (Dojo, Google, YUI, etc.) from PHP, JSP, JSF and now Roller. To use a widget, all you have to do is call a method or include a tag and JMaki takes care of including the right JavaScript files and generating the right HTML for you. That's not all JMaki does, there's also a pub/sub facility to make it easy to wire widgets together via events, there's a proxy for fetching remote resources common table and tree data models. The theme is cool widgets with ease-of-development and that's what I'd like to see in Roller. You can read more about the JMaki value proposition on the Why Use JMaki page.

Here's an example. Below is a Roller page template that uses two JavaScript widgest, the Dojo Clock and the YUI Data Table. All it takes is a single line of template code to include each widget, and one widget is dynamic i.e. the table is populated via an RSS feed.


    <html>
    <head><title>JMaki test page</title></head>
    <body>

        <h1>JMaki test: dojo.clock</h1>
        $jmaki.addWidget("dojo.clock")

        <h1>JMaki test: yahoo.dataTable</h1>
        $jmaki.addWidget("yahoo.dataTable", "/roller/xhp?id=rss","","")

    </body>
    </html>

And here's what that page looks like when displayed by Roller:

I'll write more about the plugin once I install it on this site. If you want some details about how the plugin was developed, you can read the email that I sent to the JMaki dev list: JMaki for Roller issues and suggestions. It links to the Java source code for the plugin.
