           SMC - The State Machine Compiler v. 4.0.0

Requires:  Java 1.4.1 SE (Standard Edition) or better.
Download:  http://sourceforge.net/projects/smc
Home Page: http://smc.sourceforge.net

Why use Python? You know why - powerful, flexible, simple and
                very capable.

Why use finite state machines (FSMs)? For the exact same reasons.

Computing has long since moved beyond a single process, a single
processor and single computer programming. Your application lives
in a distributed world with asynchronous events, I/O and timers.
Objects together with FSMs can handle this difficult world in
a robust and efficient manner. An object's encapsulated FSM
tracks the object's current state. The current state defines how
the object should respond to an event.

What is SMC?

SMC takes a state machine description (stored in a .sm file) and
generates State pattern classes in a target language (C++, Java,
Tcl, VB.Net, C# and Python are currently supported). SMC is a
console-based app written in Java which means SMC can run
anywhere Java (1.4.1 or better) can run. The download package
includes an example directory showing how SMC can used with C++,
Java, Tcl (requires [incr Tcl] package), VB.Net, C# and Python.
The examples range from trivial to GUI apps.

SMC generated code is trivial to hook into existing Python

    + SMC does not change your code or require you to change your
      code's logic.
    + SMC does not require that your class inherit or implement
      any SMC class.
    + SMC does not use state transition arrays or switch

An object simply instantiates the FSM and passing in its "self"
to the FSM constructor.

SMC is a mature software tool: 5 years old, in use around the
world and used in production software for the telecommunications
and financial exchanges. SMC generates code for C++, C#, Java,
Tcl, VB.Net and now Python. It is an active open source project
with new languages and features regularly added.
