State Machine

This project is a Ruby library for defining and managing object lifecycles through states, events, and transition rules. It functions as a declarative workflow engine that enforces business logic by restricting attribute changes to predefined, valid paths within Ruby classes.

The library distinguishes itself through deep integration with database persistence layers, allowing it to automatically synchronize state changes with data models, validation frameworks, and transaction management. It supports dynamic configuration, enabling the construction of lifecycle rules at runtime from external data sources, and provides diagnostic tools such as graphical visualization of state relationships and transition path analysis to audit complex workflows.

Beyond core transition management, the framework includes a callback-driven hook system for executing custom logic during lifecycle updates and provides methods for querying current object status or verifying permitted transitions. It also features dynamic method injection to handle state queries and event triggering directly on objects.

Star history

How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.

Stateless is a .NET state machine library used to manage complex object behaviors and lightweight workflows through C# code. It functions as an asynchronous workflow engine that executes state transitions, guards, and entry-exit actions using asynchronous tasks. The library implements a hierarchical state machine, allowing child states to inherit transitions and properties from parent superstates. It includes a state persistence framework that decouples state tracking from machine logic by reading and writing the current state to external properties or databases. Additionally, it features a g
