[Modeling with Pharo] How to model a simple human interaction.

Hey all..

I got my first paying gig that i am able to use pharo with, and i am on the last leg before calling it complete.

Here’s what I need to do..

This application accepts SMS text messages. It allows the user to send images via MMS and place an order to a print house for those images.. it then compiles the order, and submits it to the order processing system and makes the prints.

The last thing I need to zero in on is handling the interaction. Believe it or not, I have never modeled such an interaction. The interaction goes:

- user sends images{s)

- bot says ‘thanks’ and asks if there are more

- user types ‘done’ or sends more

- on ‘done’ bot asks for print size

- bot says ‘thanks’ and the interaction is done. order is processed.

my first inclination is to use a state machine, progressing through order each time the user enters ‘done’..

does this sound reasonable, or is there a better model/design pattern for this interaction?

Thanks!

Hi sergio

Hey all..

I got my first paying gig that i am able to use pharo with, and i am on the last leg before calling it complete.

super!

I'm really happy for you.

just this makes pharo and all our effort worth it.

Yes it seems.

After you could also have a queue of command.

or is there a better model/design pattern for this interaction?

You can look at the state pattern. It is good for implementing state machine.

Stef

Thanks!

This may be overkill for your use but would love to have an MIT licensed set of classes that allow for/enable something like this:

Looks awesome.

Now, how hard would it be to reuse a WATask from Seaside from normal, non web code?

A lot of WAxxx concepts could be brought back into nornal "Spec/Morphic" apps, like WASession, WATask, filters etc.

looks nice.

the first step is to have something basic and improve.

Indeed and we can accept them and cocoon them :)

Your using an object-oriented language, why not use an object domain model? Consider that Kristen Nygaard stated that an object-oriented "program execution is regarded as a physical model, simulating the behavior of either a real or imaginary part of the world." By physical model, he really is meaning a "direct model" where you directly represent the concepts of your problem domain as objects that interact with each other.

Sure, you could use a state machine, but why build a model (your domain problem) on top of a model (a state machine) using a paradigm intended to support a different way. State machines are a favored way to model process and state in functional programming.

A domain model would separate the user interaction from your domain problem itself. You would model an Order that knows a User and one or more Images.

Anyway, hopefully some food for thought.
