ruby - How do I override a class method through an instance_eval? -


I have a square Foo with a method bar. 

  How can I override the bar of FE with Foo.instance_eval? Def short #do some different end end

What to override: 

  Module ORM square foo def bar # some end and end  < Need to use / pre> 
  instance_eval , works with  class_eval  overrides but do not have context

Assume that you want to change the module so that whenever it is included, your new bar () will be used, you were very close: 

  Module ORM Square Foo Def Bar "Old Bar" and End and Larm :: FuClash_Avalde Bar is included in "New Bar" and Class. Lorem Foo.new.bar # = & gt; "New bar" end

I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
