By admin // Dev, Palm, SDK, WebKit // 1 Comment

After I was rejected for the early access then struggled with the “leaked” version of Palm Mojo SDK without a documentation, today Palm finally made the official SDK available for all!!!

I haven’t playing around with it long enough to blog much about it, so I just post my “cheat sheet” that I keep on Stickies.

Emulator Key for Mac

Esc – acts as “Back”
Left / Right arrows – Switch between applications

Emulator Navigation

“Host” = Right Ctrl in Virtual Box

Host + F – Toggle full screen view on/off
Host + N – Display session info
Host + S – Take a snapshot (will be placed the Snapshot tab of VirtualBox)
Host + Q – Close the emulator

Commands

Create a package (.ipk file)

$ cd palm-package myapp

Install the .ipk file on emulator

$ palm-install com.yourdomain.app.myapp_1.0.0_all.ipk

Launch the app on emulator

$ palm-launch com.yourdomain.app.myapp

Launch the inspector with the app

$ palm-launch -i com.yourdomain.app.myapp

Then, open Palm Inspector app (comes with SDK) from your Application by double-clicking the icon. This should open the Safari inspector.

Developing Applications for Palm webOS

By admin // Dev, Palm, SDK, WebKit // No Comments

The Developing Applications for webOS webcast is now available from O’Reilly.
Mitch Allen, Palm’s Software CTO, gives a preview into application development with the Mojo SDK, explaining the structure of webOS, and demonstrates how to build a simple app with using TextMate and Safari on Mac.

According to the Webcast, the Mojo framework is based on Prototype 1.6.3 is bundled with webOS. (Pssst. the rumor said it also uses Dojo and mootools! sounds pretty heavy. If it is true, this should be rather called Moojo). And apps can be written with simple html, css and javaScript just like any web development, also with HTML5 local db strage and Mojo extension for widget, with a special x-mojo-element attribute.

The SDK will come with Mojo framework and doc, an emulator with DOM inspector and JS debugger (I guess we can just use Webkit), and tool bundles including project generator and package tools.

Also, the first chapter of the book, Palm webOS: Developing Applications in JavaScript Using the Palm Mojo Framework” by O’Reilly is available at http://developer.palm.com. You can read it either html or download pdf.

Palm Got its Mojo

By admin // Dev, Palm, SDK, WebKit // No Comments

Happy new year, and happy new government, America!
I am still recovering from flu I got while visiting freezing New York City, and finally feel like blogging again.

The first topic I write in this year, besides Whitehouse 2.0 and Steve Jobs’ health is a whole new Palm.

I know it is not a new news anymore, but I was shocked when they announced Palm Pre at CES (although I have not been there since nobody sends some lowly engineers to Vegas). Honestly, after Blackberry then iPhone, I though there’s no way Palm can win the market again, so it is shocking to see their stock price rising after the announcement.

As a web developer, great news for me is that Palm will switch their web browser engine to Webkit. Since 200 when Palm acquired Handspring, their standard web browser was Blazer, running on Palm OS.
Now Palm OS has become legacy and, will have a completely new OS, called “WebOS”. which is based on Linux.

Palm webOS applications are easy to write using Mojo – a new application framework based on the HTML5, CSS, and JavaScript
Yesh! HTML5! – means you can even use offline database!
Also, reportedly Adobe is working on a Flash plug-in for the webOS browser.

Interestingly, Ajaxian has reported that Dojo is used as a base for Mojo.
The Mojo Framework source code can be found on Palm’s site.

The official Palm Mojo SDK is not available yet, but stay tuned by following the developer’s blog.

Additionally, unlike iPhone, which uses Samsung’s S3C6400 processor, Pre even has wicked fast processor, TI OMAP 3440, which embeds Imagination Technologies’ POWERVR SGX graphics core, suitable for advanced multimedia.
