Sismic Interactive State Machine Interpreter and Checker
--------------------------------------------------------

Statecharts are a well-known visual language for modeling the executable behavior of complex reactive event-based systems.
The Sismic library for Python >= 3.4 provides a set of tools to define, validate, simulate, execute and debug statecharts.
More specifically, Sismic provides:

- An easy way to define and to import statecharts, based on the human-friendly YAML markup language
- A statechart interpreter offering a discrete, step-by-step, and fully observable simulation engine
- Synchronous and asynchronous simulation, in real time or simulated time
- Support for communication between statecharts and co-simulation
- Built-in support for expressing actions and guards using regular Python code
- A design-by-contract approach for statecharts
- A unit testing framework for statecharts, including generation of test scenarios

Sismic provides full support for the majority of the UML 2 statechart concepts:

- simple states, composite states, orthogonal (parallel) states, initial and final states, shallow and deep history states
- state transitions, guarded transitions, automatic (eventless) transitions, internal transitions
- statechart variables and their initialisation
- state entry and exit actions, transition actions
- internal and external events, parametrized events, timed events

In addition to this, contracts can be specified to express invariants, pre- and postconditions on states, transitions and the statechart itself.

The Sismic library is written in a modular way:

- The semantics of the statechart interpreter is based on the specification of the SCXML semantics (with a few exceptions),
  and can be easily tuned to other semantics.
- While currently, contracts, guards and actions are expressed in Python, this support can be easily extended to other languages.


Installation
------------

Sismic can be installed using ``pip`` as usual: ``pip install sismic``.
This will install the latest stable version.

You can also install Sismic from this repository by cloning it.
The development occurs in the *master* branch, the latest stable distributed version is in the *stable* branch.

Sismic requires Python >=3.4 but should also work with Python 3.3.

Documentation
-------------

The latest version of the documentation is available at http://sismic.readthedocs.org/
.

It can also be directly built from the ``docs/`` directory using Sphinx.
