Deferrable Gratification (DG) facilitates asynchronous programming in Ruby, by helping create abstractions around complex operations built up from simpler ones. It helps make asynchronous code less error-prone and easier to compose. It also provides some enhancements to the Deferrable API. Features include: * fluent (aka chainable) syntax for registering multiple callbacks and errbacks to the same Deferrable. * a #bothback method for registering code to run on either success or failure. * a combinator library for building up complex asynchronous operations out of simpler ones.

Makes ActiveRecord defer/postpone saving the records you add to an habtm (has_and_belongs_to_many) or has_many association until you call model.save, allowing validation in the style of normal attributes. Additionally you can check inside before_save filters, if the association was altered.

The Deferring gem makes it possible to defer saving ActiveRecord associations until the parent object is saved.

Rack middleware to inflate incoming Gzip data from HTTP requests.

Presenters are easier with delegators, and other friends

ActiveSupport's delegation syntax is much more convenient than Ruby's stdlib Forwardable. This gem just extracts it as an independent functionality (available on-demand without monkey-patching Module).

flag database records as deleted and hide them from subsequent queries

Adds a new :dependent option for ActiveRecord associations that recursively deletes all dependent records without instantiating them.
