Sleep2 
Ruby sleep with extra magical stuff. These extra stuff will be useful when you are developing an algorithm with some kind of delay patterns such as in animation.
Installation
Add this line to your application's Gemfile:
gem 'sleep2'And then execute:
$ bundle
Or install it yourself as:
$ gem install sleep2
Usage
Don't forget to require 'sleep2' first.
Do math with sleep.
>> sleep = Sleep2[2] # no sleep when instantiating
#=> #<Sleep2:0x2afc2eaef970>
>> sleep # sleeps for 2 seconds
#=> #<Sleep2:0x2afc2eaef970>
>> delay = sleep * 2 # instantiate new sleep object (therefore no sleeping yet)
#=> #<Sleep2:0x2afc217b09d0>
>> delay # sleeps twice longer than sleep
#=> #<Sleep2:0x2afc217b09d0>Compare sleep with integer (in seconds) or another of its type
>> sleep if sleep > 3 # not sleeping at all since sleep duration is 2 seconds
#=> nil
>> delay = Sleep2[3] # no sleep when instantiating
#=> #<Sleep2:0x2afc2eb138c0>
>> delay > sleep ? delay : sleep # sleeps for 3 seconds
#=> #<Sleep2:0x2afc2eb138c0>Change current instance duration
>> freeze = Sleep2[3] # no sleep when instantiating
#=> #<Sleep2:0x2afc2262c2c0>
>> freeze[4] # no sleep when changing duration
#=> 4.0
>> freeze # sleeps for 4 seconds
#=> #<Sleep2:0x2afc2262c2c0>Contributing
