 The `ostruct` library comes pre-packaged with Ruby. No installation is necessary.
 
 ## Usage
 
-```
+```ruby
   require "ostruct"
 
   person = OpenStruct.new
   person.name = "John Smith"
   person.age  = 70

 An OpenStruct employs a Hash internally to store the attributes and values and can even be initialized with one:
 
-```
+```ruby
   australia = OpenStruct.new(:country => "Australia", :capital => "Canberra")
     # => #<OpenStruct country="Australia", capital="Canberra">
 ```
 
 Hash keys with spaces or characters that could normally not be used for method calls (e.g. <code>()[]*</code>) will not be immediately available on the OpenStruct object as a method for retrieval or assignment, but can still be reached through the Object#send method.
 
-```
+```ruby
   measurements = OpenStruct.new("length (in inches)" => 24)
   measurements.send("length (in inches)")   # => 24
 
   message = OpenStruct.new(:queued? => true)
   message.queued?                           # => true

 Removing the presence of an attribute requires the execution of the delete_field method as setting the property value to +nil+ will not remove the attribute.
