Hiccdown methods should live in their own, separate classes. How about they are called ‘displays’?

1
2
3
4
5
ruby
class ProductsDisplay
  def index vc, # …
    vc.some_helper_method
  end
end

Behind the scenes, the Hiccdown gem would need to make the instance variables available to the display class:

1
2
3
4
5
6
7
8
ruby
display = @display_module.new

view_context.instance_variables.each do |iv|
  display.instance_variable_set(
    iv,
    view_context.instance_variable_get(iv)
  )
end

Then:

1
2
3
4
5
ruby
class ProductsDisplay
  def index vc, # …
    vc.some_helper_method(@products)
  end
end

Then how would you call index from a helper method?

I don’t think that’s something people would do a lot, but they still easily could: ProductsRenderer.index(self)

Test this!

Tested, it works. self does indeed point to the view_context in the helper. Verified by printing object_ids.

Not as of #330, they couldn’t.

It doesn’t really matter. This would be like calling a controller action from a helper method. Not something people do.

I’m trying this now. Having to prepend every invocation of a helper method with vc. is getting really old really fast.
