Subject: Re: module private methods inheritance ?

Thanks for your help,

I finally decided to create a new Module#insert method :

class Module
  def insert(new_mod)
    new_mod = new_mod.dup
    old_mod = self
    mod_name = self.basename

    new_mod.module_eval do
      include old_mod
    end

    (nesting[-2] || Object).module_eval do
      remove_const mod_name
      const_set mod_name, new_mod
    end
  end

  # From the Facets package
  def nesting
    n = []
    name.split(/::/).inject(self){ |mod, name| c = mod.const_get(name)
; n << c ; c }
    return n
  end

  # From the Facets package
  def basename
    if name and not name.empty?
      name.gsub(/^.*::/, '')
    else
      nil #inspect.gsub('#<','').gsub('>','').sub(':', '_')
    end
  end
end


I know that I can have unwanted effects but in my case it is ok
because the loading order is pretty strict.

module A
  def initialize; puts "From A"; end
end

module B
  def initialize; puts "From B"; super; end
end

A.insert(B)

class C
  include A
end

C.new
#=> From B
#=> From A
