Quick Start

Drawing a simple automata

1. Run FSME
2. Click New button or select it from menu
3. You will see a tree browser for your Finite State Machine. Click anywhere in this tree (on some item, of course :-)
4. If the selected element can be edited, you will see an editor in the lower right part of the application. Move somewhere to achieve it. You should see something like this.

You should see something like this

Almost everything except load/save operations is done with embedded editors. I hate dialogs :-). Just click and do.

Making source code from automata

Use fsmc for this purpose. This is a program simular to QT uic. Here is an example:

fsmc file.fsm -o file.h
fsmc file.fsm -i file.h -o file.cpp

or, if you prefer python,

pyfsmc file.fsm -o file.py

Output of fsmc are C++ header and source code of the automata.

• events are translated to enum FSMName::Events,
• inputs are pure virtual boolean parameterless functions,
• outputs are pure virtual void parameterless functions.
• states are translated to enum, and FSMName::currentState() returns current state of the automata.

Here's an example generated automata header

#ifndef SampleFSM818378331
#define SampleFSM818378331
#include <queue> // for event queue

class SampleFSM {
public:
  enum Event { Event };
protected:
   virtual bool input() const = 0; 


   virtual void output1() = 0; 
   virtual void output2() = 0; 

public:
  enum States { InitialState, WorkState }; // states

private:
   States __Y;
   bool __recurseLock;
   std::queue<Event> __events; 
   void __processEvent( Event e );
public:
   SampleFSM() : __events() { __Y = InitialState; __recurseLock = false; }
   virtual ~SampleFSM() {}
   States currentState() { return __Y; }
   static const char* eventName( Event e );
   static const char* stateName( States s );
   void A( Event e );
};

#endif

To make something sensible, proceed here.
