Hi to everyone,
let's say I've the following astonishing module:
···
------------------------------------------------------
module Mod # contained in the file "mymodule.rb"
CONST = 1974
def initialize()
@initialized_value=892
end
def metodo1()
puts "this is metodo1"
end
class MyModClass
attr_reader :mymodclass_value
def initialize()
@mymodclass_value = 2005
end
end
module_function :metodo1
end
------------------------------------------------------
is it correct that "module_function :metodo1" should allow me to access to "metodo1" the following ways:
------------------------------------------------------
require 'mymodule'
Mod.metodo1() # This is Ok, and works as expected
class MyClass
include Mod
attr_reader :myclass_value
attr_reader :initialized_value
def initialize()
super()
@myclass_value = Mod::CONST
end
end
temp = MyClass.new()
temp.metodo1() # without the module_function, this works!
------------------------------------------------------
Why the line "temp.metodo1()" gives the error:
"Private method 'metodo1' called for..." ?
The Pickaxe book states that using "Module#module_function" actually makes a copy of the methods and not an alias.
Thanks again for your help.
Regards,
Carmine
