 1) show help:

   

$ java -jar ./Smc.jar -help

  2) generate java (c, cpp, js, python, object-c ...) classes from user_defined.sm file:

  

$ java -jar Smc.jar -c++ user_defined.sm

$ java -jar Smc.jar -graph -glevel 1 user_defined.sm

 A

Filename.dot file also generated (Filename should replaced by actural dot filename).

  

$ java -jar ./Smc.jar -java7 user_defined.sm

3) generate a workflow map

You need graphviz installed first, and add path to .../bin/dot.exe into system environments. in my pc, that is:

       C:\DEVPACK\graphviz-2.38\release\bin

   Now enter folder of Filename.dot generated in step 2), and type:
 

$ dot Filename.dot -Tpng -o Filename.png

 Enjoy it!

Part2: Example

1) user_defined.sm. The only file we should created by hands

///
// ColorTable.sm
//   -- ColorTable State Map for C++ classes auto-generation
//
// 1) generate c++ classes:
//   $ java -jar Smc.jar -c++ ColorTable.sm
//
// 2) generate graphviz dot graph:
//   $ java -jar Smc.jar -graph -glevel 1 ColorTable.sm
//

Shuffle
Entry {
    enterShuffle();
}
Exit {
    leaveShuffle();
}
{
    Next [ context.getOwner().shuffleDone() ]
        Swappable {
            //=>user swap actions
        }
}


Swappable
Entry {
    enterSwappable();
}
Exit {
    leaveSwappable();
}
{
    Next [context.getOwner().swapDone() && context.getOwner().canErase()]
        Erasable {
        }
    Next [context.getOwner().swapDone()]
        Shuffle {
        }
}


Erasable
Entry {
    enterErasable();
}
Exit {
    leaveErasable();
}
{
    Next [ context.getOwner().eraseDone() ]
        Collapse {
        }
}


Collapse
Entry {
    enterCollapse();
}
Exit {
    leaveCollapse();
}
{
    Next [context.getOwner().collapseDone() && context.getOwner().canErase()]
        Erasable {
        }
    Next [context.getOwner().collapseDone()]
        Crash {
        }
}


Crash
Entry {
    enterCrash();
}
Exit {
    leaveCrash();
}
{
    Next [ context.getOwner().crashDone() && context.getOwner().canErase() ]
        Erasable {
        }
    Next [ context.getOwner().crashDone() ]
        Swappable {
            //=>user swap actions
        }
}
%%

2) generate all derived files(default is c++):

$ java -jar Smc.jar -graph -glevel 1 ColorTable.sm

3) generate flow map using graphviz:

$ dot ColorTable.dot -Tpng -o ColorTable.png
