= I dont give a shit (idgas)

Inspired by groovys questionmark-syntax. 'I dont give a shit' tries to implement this behavior in ruby.

You can put a ? behind every method-call to ignore, weather it returns nil.

So chaining of calls within deep data-structures is painless:

	some_data_that_might_contain_nil.order?.shoppingcart?.item?.second?.price?

This call would return the price of the second item in the shopping-cart or +nil+ if some of the objects in the data-structure is +nil+ itself.

== Install

  $ gem install phoet-idgas -s http://gems.github.com

== How to use

Just require the gem and put it in a place where it can override the default behavior of your script. 

You might put it as an initializer in your rails application or something like that.

	$ irb -rubygems

	require 'i_dont_give_a_shit'

	

	nil.i?.dont?.give?.a?.shit?

	=> nil
