• 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?
