5. Agenda What is webOS? Where is it headed? Developing Debugging Things to think about Code (if we have time) Demo a quick app

6. What is webOS? Introduced by Palm in 2009 Acquired by HP in 2010 The key asset and primary motivation for the purchase of Palm by HP at this time Runs on a Linux Kernel Current versions webOS 2.x (mojo): phones webOS 3.x (enyo): tablets

7. What is the Future? webOS and Windows dual-booting on HP desktops and laptops Sometime in 2012 Phones– Pre3 imminently, others soon.

8. Developing in webOS 2 ways to develop SDK PDK Enyo PDK Plug-In Development Kit Geared towards game developers Utilizes C++ Allows developers of games on other platforms to port their software to webOS

9. Enyo SDK Primary development kit for webOS developers Utilizes JSON objects and JavaScript to create a UI and set up events and methods. Generates HTML5 and CSS3 to support the UI

10. IDE Concerns Eclipse Mostly useful for mojo apps Can theoretically be used for enyo JetbrainsWebStorm Again, mostly useful for mojo Somewhat more user-friendly than eclipse Notepad++ My preferred IDE Console2 Use to run command-line tools Handle source control things

11. Command-Line Tools Palm-Generate Limited to Mojo Palm-Package Generate a package file, which can be installed on webOS devices Palm-Install Install a package file Palm-Launch Launch and installed app Palm-Log Display Console Log info for webOS Apps Palm-Run Package, install, launch and app, then log all the output to the console. This is the single coolest command-line tool in the debugging arsenal.

12. Debugging with Chrome The main tool for debugging an Enyo app is Chrome Requires a couple of switches on the command line "C:rogram Files (x86)ooglehromepplicationhrome.exe" --allow-file-access-from-files --disable-web-security --enable-file-cookies I typically set up a shortcut from the desktop

13. Debugging via Emulator Once things are working in Chrome, you’ll want to test in an Emulator Uses Oracle Vbox Use Palm-Run to send to the Emulator Make sure you power down the emulator after a debugging session, or you will lose network connectivity Fairly fast power-up time – nothing like Android Emulator.

14. Reasons to use webOS HP is backing this fairly heavily By 2012, all desktops, laptops, and devices will dual-boot webOS and Windows The framework is easy to work with There’s an awesome community of developers working on cool stuff It’s a lot of FUN!!!

15. Gotchas Tooling is rough Notepad is cool, but intellisense would be nice! Palm-Generate is only for mojo Not a big deal, but left me scratching my head Documentation is available, but not obvious The API Reference at https://developer.palm.com/content/api/reference/enyo/enyo-api-reference.html is awesome!
