Drupal 8 Theme System: hook_theme() to Twig template

The Twig templating engine is in Drupal 8 and has generated a lot of excitement. Many passionate contributors have stepped up during the Drupal 8 development cycle to not only convert Drupal’s markup to Twig but also clean up and simplify the theme system as a whole. But what does all this mean to you?

In this session we will walk through the state of Drupal 8's theme system. We'll talk about what's different from Drupal 7 but also walk through some of the internals of different aspects of the theme system and how they might affect your day-to-day work with Drupal.

We’ll also talk about some of the exciting ways that Twig and Drupal 8 can be leveraged and built upon to make life better and touch on some opportunities there are in the contrib space.

This is a theming session for developers, we’re going to talk a lot about code and APIs and look at plenty of PHP, so an understanding of PHP basics will be helpful.

Topics include:

  • A high-level overview of the changes to the theme system in Drupal 8.
  • Some of the goodies that are possible now that we’re using Twig as our templating engine.
  • Using theme hook suggestions to cut down on custom code and have themers thanking you.
  • Phases of the theme system and where you can step in to alter things.
