A Ruby library that adds support for creating state machines for attributes on any Ruby class. It provides states, events, transitions, callbacks, and integrations with ORMs like ActiveRecord, Mongoid, and Sequel.

Use cases

• manage object state transitions in ruby
• define a finite state machine for a ruby class
• add state machine to activerecord model
• replace boolean flags with state-driven behavior
• add before/after transition callbacks to model lifecycle
• visualize state machine transitions with graphviz

When to choose

• you need state machines on plain ruby classes or ORM models
• you want transition hooks, predicates, and namespaced states
• you need integrations with ActiveRecord, Mongoid, DataMapper, or Sequel

When to avoid

• you are not working in Ruby
• you need a modern actively developed alternative with newer Ruby support
• you only need simple boolean flags without complex transitions
