### IRB integration ###
To use awesome_print as default formatter in irb and Rails console add the following
code to your ~/.irbrc file:

    require "awesome_print"
    AwesomePrint.irb!

### PRY integration ###
If you miss awesome_print's way of formatting output, here's how you can use it in place
of the formatting which comes with pry. Add the following code to your ~/.pryrc:

    require "awesome_print"
    AwesomePrint.pry!

### Logger Convenience Method ###
awesome_print adds the 'ap' method to the Logger and ActiveSupport::BufferedLogger classes
letting you call:

    logger.ap object

By default, this logs at the :debug level. You can override that globally with:

    :log_level => :info

in the custom defaults (see below). You can also override on a per call basis with:

    logger.ap object, :warn

### ActionView Convenience Method ###
awesome_print adds the 'ap' method to the ActionView::Base class making it available
within Rails templates. For example:

    <%= ap @accounts.first %>   # ERB
    != ap @accounts.first       # HAML

With other web frameworks (ex: in Sinatra templates) you can explicitly request HTML
formatting:

    <%= ap @accounts.first, :html => true %>

### Setting Custom Defaults ###
You can set your own default options by creating ``.aprc`` file in your home
directory. Within that file assign your  defaults to ``AwesomePrint.defaults``.
For example:

    # ~/.aprc file.
    AwesomePrint.defaults = {
      :indent => -2,
      :color => {
        :hash  => :pale,
        :class => :white
      }
    }

### Running Specs ###

    $ gem install rspec           # RSpec 2.x is the requirement.
    $ rake spec                   # Run the entire spec suite.
    $ rspec spec/logger_spec.rb   # Run individual spec file.
