Palm Ares SDK to add drag-and-drop JavaScript functionality to webOS

Sunday, 08 November 2009 Andrew Young

For those still learning the ropes to webOS, Palm will be introducing a new web-based development environment for webOS applications called Ares by the end of the year. The new toolkit, unveiled recently at the Open Mobile Summit conference in San Francisco, is designed to make it easy to integrate components in JavaScript in building webOS apps for the Pre and Pixi.

In the demo, a Palm engineer created a search application for Flikr. Using a simulation of the webOS interface, he dragged logos, a search field, button, list widget and other components to successive screens, and linked the app to Flikr using an Ajax request that called a Flikr API. Ares then allowed him to see a preview of the app in both portrait and landscape view using the phone emulator.

To simplify the development process, the tool will also allow you to package up the completed app, download it to the Pre or Pixi, share it with friends; even submit it to the App Catalog. It will be compatible with a variety of browsers, including Firefox and Safari. According to Palm's senior VP of application software, Michael Abbott, Ares is designed to help web developers make the leap to mobile development, and won't require any downloads or configuration, as well as including debugging and a way for developers to share libraries and APIs.

This looks like a useful web tool that should help streamline the app building process and attract some new talent to webOS. Do you plan to use Ares when it is released?

It was good enough having the ability to code in HTML, CSS, etc. but now offering a UI with increased API is going to make development faster and easier. This is where Palm takes the market on development.

Oh hecks yeah Palm knows what they are doing on the software side. Now they just need some upgrades on the hardware side such as battery life!!! Or a video camera on the phone. Then we'd be talking.

Interesting technology, especially the drag and drop and flickr search functionality

If you want to import or create an existing project in Ares without using the Interface Builder, you can do so entirely in the code editor portion and the application will be no different than an existing Mojo application. If you use the visual Interface Builder, there is an additional -chrome.js file for each view. This file is JSON metadata created by the Interface Builder, and contains extra code that supports the visual and advanced layout aspects of Ares. How this differs from regular Mojo is there is a scaffolding of container objects that handle layout, and at runtime Mojo widgets are instantiated in those containers. You can mix and match Ares and regular scenes in your application, but if you try and mix the two within the same scene, your mileage may vary and this is not supported. You can import an existing mojo application for the purposes of debugging or log viewing or editing. This is fully supported and encouraged, as Ares offers a vastly improved debugging experience over the current toolset.

Leather texture

True packets of grain is deep, if blisters particles oflv bags the gap between comparative trenchant, as is the width of the

ditch between particles are very average. The whole feels soft hard moderate, more flexible. Leather texture like itself has a plane, and then put the irregular

blisters grain bits of feeling, and auxiliary up every grain of bubble grain the gaps between the very well and have certain depth. And every grain shop up blisters

height depth, looking more uniform also texture.
