@GLOBAL_CONSTANT  = "#{variable}"

Pry

Pry is amazing Pry is the interactive debugging library for ruby, it gives you the ability to set debug points in your application and debug from there e.g. inside a method

require 'pry' ; binding.pry

or

require 'pry-remote'; binding.remote_pry

Namespacing

Namespaces are done by methods and classes, you can access an namespace by using :: e.g.: mattivdweem::translate::translationset to access the top/main/root scope you can simpely use ::wacha_wanna_reach with nothing before the first ::

Packagemanager

Ruby uses gems for it's dependency's, gems can be installet by gem install *your gem* or by creating a Gemfile when a gem file is read by bundle it will download the gems for you.
