Dynamic super-overridable methods in Ruby – The Pug Automatic

The linked article Show archive.org snapshot shows how metapogramming macros can use define_method to make a method that can be overridden with super in the same class.

Helper

You can use the with_module_inheritance helper below if you want. It can be handy to make parts of a modularity Show archive.org snapshot trait super-able:

module StripAttribute
  as_trait do |attr|
    with_module_inheritance do
      define_method "#{attr}=" do |value|
        write_attribute(attr, value.strip)
      end
    end
  end
end

The helper implementation is here:

# ./lib/ext/module/with_module_inheritance.rb
#
# This macro allows you to define methods in a modularity trait that can be
# modified using the `super` keyword
# See https://thepugautomatic.com/2013/07/dsom/
module WithModuleInheritance
  def with_module_inheritance(&block)
    anonymous_module = Module.new
    include anonymous_module
    anonymous_module.module_eval &block
  end
end
Module.include(WithModuleInheritance)
