Using 'include' but not poluting my namespace

ruby-talk
1

I noticed that if you 'include' a module within a method, it will polute the namesapce that defines that method. I found a simple solution is to declare a throw-away class, and execute my code in that. Is there a more better way to achieve this?

# Pollutes current namespace
def init()
   include Inertia

   do_stuff_with_inertia()
end

# Doesn't polute namespace, but ugly
class DontPolute
   include Inertia

   do_stuff_with_inertia()
end

both pollute your namespace equally. the first pollutes class Object, the
second class DontPolute. remember that you're code in ruby, if not inside a
class, is inside the Object class. this allows you to pretend your coding
something like perl. i always write main programs like so

   class Main
     ...
   end

   Main::new if $0 == __FILE__

to avoid any such issues.

if you are looking for a workaround you can also use

   Module::new{ include Inertia ... }

knowledge is important, but the much more important is the use toward which it
is put. this depends on the heart and mind of the one who uses it.

Instead of include, you may want:
require 'intertia'

This will load up inertia.rb, which i'm assuming contains either a class or a
module name Intertia. Then you can use it via Interia.new() or
Intertia::do_stuff_with_intertia().

Correct me if I'm misunderstanding what you're trying to do here.
