Gibbler 0.5 ALPHA

Git-like hashes and history for Ruby objects.

Installation:
$ gem install gibbler

Examples:
    require 'gibbler'

    "kimmy".gibbler              # => c8027100
    :kimmy.gibbler               # => 52be7494

    config = {}
    config.gibbler               # => 4fdcadc6
    config.gibbled?              # => false

    config[:server] = {
      :users => [:dave, :ali],
      :ports => [22, 80, 443]
    }
    config.gibbled?              # => true
    config.gibbler               # => ef23d605

    config[:server][:users] << :yanni

    config.gibbler               # => 4c558a56

    config.gibbler.short         # => 4c558a56


Gibbler can also keep track of the history of changes to an object. By
default Gibbler supports history for Hash, Array, and String objects.
The gibbler_commit method creates a clone of the current object and
stores it in an instance variable using the current hash digest as the
key.

    require 'gibbler'
    require 'gibbler/history'

    a = { :magic => :original }
    a.gibbler_commit             # => d7049916

    a[:magic] = :updated
    a.gibbler_commit             # => b668098e

    a[:magic] = :changed
    a.gibbler_commit             # => 0b11c377

    a.gibbler_history            # => d7049916, b668098e, 0b11c377

    a.gibbler_revert! 'd7049916' # Return to a specific commit
    a.gibbler                    # => d7049916
    a                            # => { :magic => :original }

    a.delete :magic

    a.gibbler_revert!            # Return to the previous commit
    a.gibbler                    # => 0b11c377
    a                            # => { :magic => :changed }


    a.gibbler_object 'b668098e'  # => { :magic => :updated }
    a.gibbler_stamp              # => 2009-07-01 18:56:52 -0400
