Ruby:如何在IRB中将命名空间类包含到全局命名空间中 [英] Ruby: How to include namespaced classes into global namespace in IRB

问题描述

由于某种原因，我想使用命名空间的类/模块，因为它们位于IRB的全局命名空间中.

For some reason I want to use namespaced Classes/Modules as they are in global namespace in IRB.

例如，我内部有模块MyCore和类MyUser.是否有任何机制或挂钩可以让IRB包括MyCore::MyUser，而我可以只调用MyUser.new而不用MyCore作为前缀?

For example I have module MyCore and class MyUser inside it. Is there any mechanism or hook for IRB to include MyCore::MyUser in a way I can call just MyUser.new without prefixing it with MyCore?

推荐答案

您可以轻松完成

include MyCore

myUser = MyUser.new

使用include将模块中的所有常量添加到您当前的类中.

Using include adds all the constants in the module to you current class.

class WhereIWantToIncludeMyCore
  include MyCore

  def initialize
    user = MyUser.new
  end
end

如果您希望能够在任何地方执行 ，则可以将其添加到class范围之外，该范围将包括在Object中.

If you want to be able to do that everywhere, you can add it outside the scope of a class, which will include it to Object.
