Desktop Apps with PHP and Titanium (php|tek 2010)

Desktop Apps with PHP and Titanium (php|tek 2010)

The Web is a vital part of our daily lives, and as we begin using the Web for tasks traditionally performed on the desktop, such as word processing, software as a service (SaaS) and software + services models are becoming more important. Web developers are caught in the cross hairs of these merging industries. They have the know-how of web development but, often, none of the skills for traditional desktop or mobile development.

Enter Titanium. Appcelerator Titanium is an open source platform for developing native desktop and mobile applications using the web technologies you’re already familiar with. Now, web developers can use their skills to develop for both the Web and desktop/mobile platforms. Ben Ramsey will demonstrate how to create a simple application in Titanium Desktop, showing examples using JavaScript and PHP working together in the Titanium run time environment to power dynamic desktop applications that communicate easily with external web services.

  2. Hi, I’m Ben. benramsey.com @ramsey joind.in/1576

  3. DISCLAIMER: I’m not a salesman & I don’t work for

    Appcelerator.
  4. DISCLAIMER: I helped with the initial embedding of PHP in

    Titanium.
  5. What is Titanium?

  6. None
  7. None
  8. Four main parts of Titanium apps • The html/css/javascript code

    that makes up the core application logic and UI • The APIs that access native device/ desktop functionality, analytics or other modular functionality • The language-OS bridge that compiles web code into native application code • The run-time shell that packages the application for cross-platform distribution
  9. Contrasting with AIR... • Titanium is released under an open

    source license • Titanium provides access to native controls • Titanium applications are packaged for a target system: Windows, OS X, Linux
  10. Who is Appcelerator?

  11. None
  12. Appcelerator’s role • Developed and own’s Titanium source • Licenses

    Titanium under Apache license • Support, training, and consulting • Analytics and tracking • Infrastructure for building and packaging releases of your apps in the cloud
  13. How Appcelerator makes money...

  14. So, why PHP on Titanium?

  15. • Titanium already had modules to support Python and Ruby

    development • PHP was on their roadmap • PHP is a natural scripting complement to other web technologies • It was cool and fun to do • I can now build desktop apps with PHP without using PHP-GTK (no offense to the maintainers of PHP-GTK)
  16. Using Titanium Developer

  17. None
  18. None
  19. None
  20. • Fill out your application details • Click “Create Project”

    • Click the “Test & Package” tab • Click the “Launch App” button
  21. None
  22. Now, you have code!

  23. Installation on Linux • There is a known issue with

    the GTK libraries for Titanium Developer on Linux • Until there is a fix, do this after installing Titanium Developer: •cd ~/.titanium/runtime/linux/1.0.0 •rm libgobject* libgthread* libglib* libgio*
  24. “Hello, World.”

  25. None
  26. <html> <head> <title>Hello, World!</title> </head> <body> <h1>Hello, World!</h1> </body> </html>

  27. None
  28. None
  29. var mainMenu = Titanium.UI.createMenu(); mainMenu.appendItem(Titanium.UI.createMenuItem("File")); var menu = Titanium.UI.createMenu(); menu.appendItem(Titanium.UI.createMenuItem("Quit",

    function() { if (confirm("Are you sure you want to quit?")) { Titanium.App.exit(); } })); mainMenu.getItemAt(0).setSubmenu(menu); Titanium.UI.currentWindow.menu = mainMenu;
  30. None
  31. Titanium provides APIs... • API • Analytics • App •

    Codec • Database • Desktop • Filesystem • JSON • Media • Network • Notification • Platform • Process • UI • UpdateManager • Worker
  32. Drop in external libraries

  33. Accessing these APIs and libraries • JavaScript • Python •

    Ruby • PHP
  34. PHP in Titanium

  35. <script type="text/php"> // PHP code goes here </script>

  36. <script type="text/javascript"> var heading = document.getElementById("title"); heading.innerHTML = "Hello, World!";

    </script> JavaScript
  37. <script type="text/php"> $heading = $document->getElementById("title"); $heading->innerHTML = "Hello, World!"; </script>

    PHP
  38. phpinfo()

  39. <html> <head> <title>PHP Info</title> <script type="text/php"> date_default_timezone_set('America/Chicago'); ini_set('default_charset', 'utf8'); ini_set('display_errors',

    'Off'); function getPhpInfo() { ob_start(); phpinfo(); return ob_get_clean(); } </script> </head> <body style="background-color: white; padding: 10px;"> <script type="text/php"> $document->write('<pre>' . getPhpInfo() . '</pre>'); </script> </body> </html>
  40. PHP caveats • echo does not work as expected •

    Titanium state transitions (links) do not send requests • Pre-processed scripts (.php) are processed at compile/build time • Cannot inject classes defined in .php into runtime code with include/require
  41. Are some of these bugs? Maybe.

  42. Planet PHP Demo

  43. Wrapping up... • Titanium allows web developers the ability to

    create desktop apps • It builds native applications that you can distribute for a particular OS • You can combine PHP with JavaScript (and Python and Ruby) to leverage the best of each language • Still some bugs to iron out, but that’s why they need lots of people using it
  44. Questions?
