Module#include (no need for ClassMethods)

Ruby
1

If we define Module#include as:

class Module

alias _include include

def include(*mods)
  mods.each do |mod|
    if mod.const_defined?(:Self)
      extend mod::Self
      # pass it along if module
      if instance_of?(Module)
        const_set(:Self, Module.new) unless const_defined?(:Self)
        const_get(:Self).send(:include, mod::Self)
      end
    end
  end
  _include(*mods)
end

end

Example:

module X
def x; “x”; end

module Self
  def q; "q"; end
end

end

class C
include X
end

C.q #=> “q”

Benefits:

  • Documents well in RDoc
  • Fairly concise and clear
  • Self module fits in well with “class << self”
  • No callbacks used.

Clever. :slight_smile: It doesn’t seem to grok class vars inside of ::Self (?),
but class/module_eval works. Weird since class methods work without
the eval.
