119 The Classy Base Theme for Drupal 8 with Scott Reeves and David Hernandez - Modules Unraveled Podcast

## Consensus Banana

* How did this all get started? and where does the “banana” come from.

    * From Morten: 2 years ago at BadCamp John Albin was holding a plastic sword from the pirate fest the day before. It was known as the sword of consensus. At DrupalCon Austin Morten had a banana that he was using to point to people and ask “So can we agree on X?”.  That is how it became the banana of consensus. It was basically a pointing stick.

* Technically, what is the change.

    * Moving classes from core to a base theme called Classy.

    * Multi-phased approach.

    * Phase 1, move classes out of preprocess functions and into the core templates.

    * Create the Classy base theme.

    * Phase 2, copy the core template with classes to Classy, remove the classes from core.

* Why do themers need this.

    * Better options

    * Not everyone wants the same markup (themer survey)

    * Avoiding php

    * No time wasted undoing core.

* What work has been done, what is left.

    * Preprocess changes (phase 1) far along.

    * Classy is RTBC, waiting for Dries to approve.

    * Phase 2 to start at or just after Amsterdam (don’t need to wait until phase 1 is 100% complete)

* Chance of failure?

    * Changes have to be in by RC1.

* Who to thank?

    * joelpittet, mdrummond, crowdcg, lauriii, alexpott!

* Are there any other theme layer changes to look forward to that have come about because of the banana consensus?

    * addClass/removeClass is in, what about setAttribute/removeAttribute? Similarities to jQuery make this (hopefully) more approachable for frontend developers.

* Any other theming changes not related to banana?

    * Improved menu theming - menu.html.twig using a Twig macro

## Use Cases

* What it means for themers. What it means for developers.

    * Preprocess is still there so contrib can add classes if necessary - but is it necessary? Could it be done as a data- attribute?
