module Set
# 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 "<script/>"
# add_to_basket :js_tags do |format_obj|
# format_obj.render_special_view
# end
# end
module Basket
# Define a basket in a set or format
def basket name
mattr_accessor "#{name}_content"
send("#{name}_content=", [])
define_method name do
send("#{name}_content").map do |item|
item.respond_to?(:call) ? item.call(self) : item
end
end
end
# Define a basket in an abstract set
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|
super(host)
host.basket name
end
end
