Raku DSL::FiniteStateMachines

In brief

This repository is for a Raku package with class definitions and functions for creation of Finite State Machines (FSMs) and their execution.

Usage example (Address book)

Here we load the definition of the class AddressBookCaller (provided by this package) and related entities package, "DSL::Entity::AddressBook":

use DSL::FiniteStateMachines::AddressBookCaller;

use DSL::Entity::AddressBook;
use DSL::Entity::AddressBook::ResourceAccess;

Here we obtain a resource object to access a (particular) address book:

my $resourceObj = DSL::Entity::AddressBook::resource-access-object();

Here we create the FSM and show its states:

my DSL::FiniteStateMachines::AddressBookCaller $abcFSM .= new;

$abcFSM.make-machine(($resourceObj,));

.say for $abcFSM.states;

(Each pair shows the name of the state object and the object itself.)

Here is the graph of FSM's state transitions:

$abcFSM.to-mermaid-js

Remark: In order to obtain a Mathematica -- or Wolfram Language (WL) -- representation of the state transitions graph the method to-wl can be used.

Here is how the dataset of the created FSM looks like:

.say for $abcFSM.dataset.pick(3);

For an interactive execution of the FSM we use the command:

#$abcFSM.run('WaitForCallCommand');

Here we run the FSM with a sequence of commands:

$abcFSM.run('WaitForCallCommand', 
        ["call an actor from LOTR", "", 
         "take last three", "", 
         "take the second", "", "", 
         "2", "5", "", 
         "quit"]);

Object Oriented Design

Here is the Unified Modeling Language (UML) diagram corresponding to the classes in this package:

(The UML spec and the Mermaid spec above were automatically generated with "UML::Translators", [AAp5].)

Here is the MermaidJS spec generation shell command:

to-uml-spec --format=MermaidJS DSL::FiniteStateMachines
