![]() ![]() So if you want to use a module as a mix-in, and don't want to declare anything singleton, don't use the self keyword, however if you want to keep state within the object, just use a class and mix-in the modules you want.Description: I am running/executing powershell from a ruby script (.rb) file exec "powershell.exe Import-Module PSWindowsUpdate" It refers to the scope of the object within ruby's object hierarchy. The points raised above are good examples of ways to extend classes, but with modules, the hard part is when to use the self keyword. ![]() fun_ruby = Fun::Ruby.new(params)įun_ruby_hash = fun_ruby.to_hash(fun_ruby.string) Now you can format the string in your class. Now whenever you need to format an xmlstring as a hash, or remove trailing whitespace in any of your future code, just mix it in. # remove trailing white space from that idiot who pasted from textmate module Friendlyĭef remove_trailing_whitespace(string,&block) Use them whenever you think you will have to do something more than once in your code. Session::Live::Actor.new(params) do |res|. We want to know that when we make a create an Actor class that it is the correct class, so this is where namespaces come in handy. Now we have the potential for overlap in our classes. # save your callback as a class variable, and use it sometime = block # check params, insert init values for vars.etc module SessionĪttr_accessor :type, :uuid, :name, :status Now you can use this to create some sort of Tree structure in your code, without having to instantiate a new class for every call to Base::Tree.entity.Īnother way to do Namespace-ing is on a class by class basis. This is good for larger projects where there is the chance for method name conflicts module Base Will allow you to use modules as a Namespace pattern. A.) you use modules in their self contained form Base::Tree.entity(params) directly in your code, or B.) you use modules as mixins or helper methods.Ī. ![]() I am not sure if you're still wondering about this, but there are two different ways to use modules in ruby. ![]()
