[Peter Fisk:VST] .NET, JSON Arrays and Smalltalk Messages
by M. David Peterson
In regards to OOP -- Smalltalk is at the very foundation of classic Object Oriented Programming.
via [Vista:SmallTalk] On Alan Kay: It's *ALL* About Messaging
Smalltalk is not only NOT its syntax or the class library,
it is not even about classes. I'm sorry that I long ago
coined the term "objects" for this topic because it gets
many people to focus on the lesser idea.
The big idea is "messaging" -- that is what the kernal of
Smalltalk/Squeak is all about (and it's something that was
never quite completed in our Xerox PARC phase). The Japanese
have a small word -- ma -- for "that which is in between"
- perhaps the nearest English equivalent is "interstitial".
The key in making great and growable systems is much more to
design how its modules communicate rather than what their internal
properties and behaviors should be.
Think of the internet -- to live, it
(a) has to allow many different kinds of ideas and realizations
that are beyond any single standard and
(b) to allow varying degrees of safe interoperability between
Secondly, I think one of the O'Reilly servers needs a bit of a tune-up on the system clock -- Regardless of what it might seem, I promise, I didn't reply to Marcel *BEFORE* he made his original comment. ;)
None-the-less, thanks for the reminder, Marcel!
As promised, Peter Fisk has followed up yesterdays post with an overview of using JSON Arrays together with Smalltalk messages,
JSON Arrays and Smalltalk Messages � Microsoft .Net and Smalltalk
And this method in class Object can then execute the arrays as Smalltalk messages:
self perform: anArray first asSymbol withArguments: anArray withoutFirst
As an example, the TmsTicTacToe game sends two kinds of messages to the opposing player:
- a text message which appears in the chat window
- a "mark tile" message which marks a tile on the opposing player's board
For those of you who would rather chew on tinfoil than muck around with angle brackets, my guess is that this is something you will find most exciting. :)
Couple of things to note,

Welcome to Smalltalk!
Incidentally, this is "classic" OOP...
