creating simple state machine for c++11

SSM - SimpleStateMachine

Tool to generate state machines for c++11.

Features:

0. Simple description language
1. Super simple to use under C++11
2. Using Graphviz dot to generate nice diagrams

Description Language

A simple state machine: example1.sm

export MyStateMachine

MyStateMachine
	MyStateStart: once helloWorld()
		true -> MyStateFinish
	MyStateFinish:

Using it for C++11

Assuming you have following class.:

class MyClass {
public:
	void helloWorld() {
		std::cout<<"Hello World"<<std::endl;
	}
};

To use it with our state machine example1.sm. We first run ./ssm.pl --cpp11 example1.sm this will create a single example1.sm.h

	#include "example1.sm.h"
...
	MyClass myClass;

	MyStateMachine example1(&myClass);
	example1.run();

Last step is compiling: g++ -std=c++11 -o example1 example1.cpp. Done! We can run ./example1 and get the output: Hello World.

Using Graphviz

Running: ./ssm.pl --png example1.sm creates a file example1.sm.png:

You can also run ./ssm.pl --view example1.sm which will display the diagram immediatly.
