Sharing scenarios between previews?

[henrik]

Hi,

We have a shared component like AdminAndPublic::FooComponent.

We want both an Admin::FooComponentPreview and a Public::FooComponentPreview, because we want to see it rendered with both layouts (and thus styles).

We've realised we can't use modules for this, since Lookbook only looks for non-inherited public methods. Further, we noticed we can't even define methods like

module MySharedScenarios
  def self.included(klass)
    klass.define_method(:my_scenario) { … }
  end
end

Lookbook simply ignores those methods, not listing them as scenarios.

I didn't dive all the way to the bottom of this, but it seems it has something to do with YARD::CodeObjects and the preview files being parsed.

Even a define_method inside the preview class itself did not result in a scenario.

The best we could come up with was to define methods just calling super:

module SharedFooScenarios
  def my_scenario = …
end

class Public::FooComponentPreview < Public::BasePreview
  include SharedFooScenarios

  def my_scenario = super
end

Curious to hear your thoughts – how do you handle similar things? How would you suggest we handle this?

And also, I'm curious about the CodeObjects thing – if anyone wants to say more about how it currently works and why, that'd be super interesting.
