2. Drupal 8 meets Symfony Fabien Potencier @fabpot [email protected] Founder of

   Lead developer of Open-Source libraries Twig, Swiftmailer, Silex, Pirum, Sismo, Pimple, Goutte, ... Symfony founder and lead developer

3. Drupal 8 meets Symfony Lukas Kahwe Smith @lsmith [email protected] Works

   for in Switzerland PHP 5.3 Release Manager Co-lead of PHPCR Symfony2 core contributor

4. http://www.flickr.com/photos/dunechaser/160405823 Drupal 8 meets Symfony How many of you are

   PHP developers?

5. Drupal 8 meets Symfony http://www.flickr.com/photos/dunechaser/142079357 How many of you are

   Symfony “aware”?

6. Drupal 8 meets Symfony We are both “outsiders” We are

   both quite experienced PHP developers We have a rough understanding of the hook paradigm aka the Drupal way http://www.flickr.com/photos/pictureperfectpose/76138988

7. Drupal 8 meets Symfony A sad realization It would take

   a long time for us to be productive in Drupal let alone work on the core And everything we learn along the way would only help us with Drupal

8. Drupal 8 meets Symfony What others do Building on top

   of long established OO design patterns Leverage new PHP language features and performance improvements Share code!

9. Drupal 8 meets Symfony So Drupal is wrong? No, the

   question is just if the benefits of doing things differently outweigh the disadvantages

10. Drupal 8 meets Symfony Core brain drain “The complexity of

    the custom code that’s used and the non-standard architecture combines to create a barrier to entry for developers new to Drupal (both experienced and novice developers alike).” buytaert.net

11. Drupal 8 meets Symfony What could be gained Facilitate the

    refactoring towards a “framework” core Focus Drupal dev resources on the CMS Easier integration with other applications Ensure that the Drupal developer pool continues to grow

12. Drupal 8 meets Symfony A decision was made “While these

    changes may seem large, and some of them are, we believe that they will achieve the right balance between empowering Drupal's design and architecture, and moving toward more modern, standard, well-tested code and techniques to empower a new generation of developers.” buytaert.net

13. Drupal 8 meets Symfony How to collaborate? Symfony2 is MIT

    licensed which is GPL compatible Symfony2 development is very transparently managed on github.com We want to ensure Symfony2 works for Drupal, phpBB, etc.

14. Drupal 8 meets Symfony For example ... Symfony2.0 provides a

    concept called “flash messages” to pass messages to the very next request drupal_set_message() could be replaced by this if we make it a bit more flexible Drak, lead of the Zikula CMS, created a PR to address exactly these concerns
