I just thought of something really cool though I don't know much about workflow engines yet.

A pike VM based workflow engine that is - get this - TRANSACTIONAL

because this works as a series of instructions that then invoke actions, I can store up the list of actions to invoke, in priority order, and execute them only if we got to an accept state!

So basically like this:

Create or load your workflow. (builds an NFA state machine and then compiles it to bytecode)

Run your workflow by feeding the machine a series of activities. (runs the pike VM)

From there the activities trace paths through the machine. Whenever they land on certain points in the path they queue certain actions. At any time if they pass through an accept point, all the queued actions are executed. That way you can create start and end points for transactions.

I still haven't sussed this all out but what a cool idea. I think?

and a nice side benefit (plus what gave me the idea in the first place) is Pike VMs can execute NFAs faster than doing the traditional NFA traversal method.

I wonder if decision tables might be useful as a source of ideas: [^]. I use the "airfare calculation" scenario on that page in teaching programming.

If you think of "time" as a "third dimension" to a series of decision tables ... workflow ?

I remember us talking about this. I think they can be translated directly to state machines.

I'm still working on the details. I need to study workflow systems more.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
