A long-lived project that still receives updates
Workflow is a finite-state-machine-inspired API for modeling and interacting with what we tend to refer to as 'workflow'. * nice DSL to describe your states, events and transitions * various hooks for single transitions, entering state etc. * convenient access to the workflow specification: list states, possible events for particular state

There are many finite state machine implementations for Ruby, and they all provide a nice DSL for declaring events, exceptions, callbacks, and all kinds of niceties in general. But if all you want is a finite state machine, look no further: this has less than 50 lines of code and provides everything a finite state machine must have, and nothing more.

AlterEgo is a Ruby implementation of the State pattern as described by the Gang of Four. It differs from other Ruby state machine libraries in that it focuses on providing polymorphic behavior based on object state. In effect, it makes it easy to give an object different personalities depending on the state it is in.

A minimal finite state machine with a straightforward syntax. You can quickly model states, add callbacks and use object-oriented techniques to integrate with ORMs.

'State' Design Pattern from the Gang of Four book. Many other state machines focus on events and transitions. This state machine focuses on behavior and reducing conditional logic.
