Coati
Description
Coati hides user-defined instance variables from being show when inspecting an instance of the class.
Imagine you have a simple class like:
class TestClass
def initialize(username, password)
@username = username
@password = password
end
end
Then when you inspect the instance of the class, the output will be something like:
[1] pry(main)> instance = TestClass.new('Joe', 'supersecretpassword')
=> #<TestClass:0x007f9633ca87f0 @username="Joe", @password="supersecretpassword">
...even if we don't want the password value to be shown. This gem addresses this problem.
This gem is named after an American mammal.
Installation
Simply do
gem install coati
Usage
Firstly require it from the file:
require 'coati'
Then use the attr_hider method in the class:
class TestClass
attr_hider :password
def initialize(username, password)
@username = username
@password = password
end
end
When inspecting an instance of the class, the ouput will be something like:
[1] pry(main)> instance = TestClass.new('Joe', 'supersecretpassword')
=> #<TestClass:0x007f9633ca87f0 @username="Joe">
