Overview

The purpose of a basket it that you can throw something in from the same set in another mod. A basket can be defined on a format or directly on a set

@example: # mod/core/set/self/head.rb: basket :basket_on_set

format :html do basket :js_tags # only available in HtmlFormat view :core { output basket(:js_tags) } end

# mod/shell/set/self/head.rb: add_to_basket :basket_on_set, 'hello world'

format :html do add_to_basket :js_tags "

Define a basket in an abstract set

# File 'lib/card/set/basket.rb', line 38

def abstract_basket name
  # the basket has to be defined on the including set
  # (instead on the set itself)
  define_singleton_method :included do |host|
    host.basket name
  end
end

#add_to_basket(name, content = nil, &block) ⇒ Object

# File 'lib/card/set/basket.rb', line 46

def add_to_basket name, content=nil, &block
  content ||= block
  send("#{name}_content").send("<<", content)
end

#basket(name) ⇒ Object

  end
