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.
Hereâs 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 âthanksâ and asks if there are more - user types âdoneâ or sends more - on âdoneâ bot asks for print size - bot says âthanksâ 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 âdoneâ..
does this sound reasonable,
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!
