def layout layout, opts={}, &block
  Card::Layout.register_built_in_layout layout, opts
  method_name = Card::Set::Format.layout_method_name(layout)
  define_method method_name, &block
  wrapper layout do
    send method_name
  end
end

#wrapper(wrapper_name, *args, &wrap_block) ⇒ Object

Defines a wrapper method with the name "wrap_with_". Inside the wrap_block the variable "interior" is always available to refer to the content that is supposed to be wrapped by the wrapper.

Example: wrapper :burger do |opts| ["#opts[:bun]-bun", interior, "bun"].join "|" end

It can be used like this: wrap_with_burger bun: "sesame" do "meat" end # => "sesame-bun|meat|bun"

It's also possible to wrap a whole view with a wrapper view :whopper, wrap: :burger do "meat" end

Options for view wrappers can be provided using a hash or, if not all wrappers need options, an array of symbols and hashes. Example view :big_mac, wrap: { burger: { bun: "sesame" }, paper: { color: :red } } view :cheese_burger, wrap: [:burger, paper: { color: :yellow }]

If you want to define a wrapper that wraps only with a single html tag then use the following syntax: wrapper :burger, :div, class: "medium"

wrap_with_burger "meat" # => "

meat
"

Parameters:

  • wrapper_name (Symbol, String) —

    the name for the wrap method
