SMC - The State Machine Compiler v. 1.3.2

Requires: Java 1.2 SE (Standard Edition) or better.

=================================================================
What's New?
=================================================================

+ Modified push transition syntax to be:

<transname> <state1>/push(<state2>) {<actions>}

which means "transition to <state1> and then
immediately push to <state2>". The current
syntax:

<transname> push(<state2>) {<actions>}

is still valid and <state1> is assumed to be a "nil"
loopback transition followed by a push to <state2>.

I added this feature to handle the following
situation:

Waiting
{
Event1 push(Working) {}
Event2 push(Working) {}

// When returning from Event1's push, we want to
// do this ...
WorkDone(status: Status) Busy {}

// but returning from Event2's push, we want to
// do something different.
Workdone(status: Status) WaitAgain {}
}

There is no way to distinguish between these two pushes
using the pre-v. 1.3.2 syntax. But now:

Waiting
{
Event1 Event1Pop/push(Working) {}
Event2 Event2Pop/push(Working) {}
}

// This state handle's the Event1 pop ...
Event1Pop
{
WorkDone(status: Status) Busy {}
}

// and this state handle's the Event2 pop.
Event2Pop
{
Workdone(status: Status) WaitAgain {}
}

=================================================================
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
and Tcl are currently supported). SMC is a console-based app
written in Java which means SMC can run anywhere Java (1.2 or
better) can run. The download package includes an example
directory showing how SMC can used with C++, Java and Tcl
(requires [incr Tcl] package). The examples range from trivial to
GUI apps.
