The package management paradox
There was no need to build a package management system since CPAN, and yet npm is the best. Wait, what? Every time a new programming language or framework is released, people seem to decide that: It needs its own package … Continue reading
The book “NeXTstep Programming Step One: Object-Oriented Applications” by Garfinkel and Mahoney said this about Controllers in 1993: A good rule of thumb is to place as little code in your controller as necessary. If it is possible to create … Continue reading
Dogmatic paradigmatism
First, you put all of your faith in structured programming, and you got burned. You found it hard to associate the operations in your software with the data upon which they act, and to make sure that the expectations made … Continue reading
*-Oriented Programming
Much is written about various paradigms or orientations of programming: Object- (nee Message-) Oriented, Functional, Structured, Dataflow, Logic, and probably others. These are often presented as camps or tribes with which to identify. A Smalltalk programmer will tell you that … Continue reading
Protocol-Oriented Programming in Objective-C
Hi, this is a guest post from Crusty. I’ve been doing a tour of the blogosphere, discussing Protocol-Oriented Programming. This time, Graham was kind enough to hand over the keyboard for SICPers and let me write a post here. Back … Continue reading

Functional Programming in Object-Oriented Programming in Functional Programming in Swift
The objects that I’ve been building up over the last few posts have arbitrarily broad behaviours. They can respond to any selector drawn from the set of all possible strings. As with all art, beauty is produced by imposing constraints. … Continue reading

Classes in objects in object-oriented programming in functional programming in Swift
So far, Objective-Swift objects have used prototypical inheritance, in which they supply some methods but also know about another object to which they can forward messages they don’t understand themselves. This pattern is used in languages like Self, JavaScript and … Continue reading

Mutable objects in immutable objects in object-oriented programming in functional programming in Swift
I didn’t realise this at the time, the previous entry wasn’t the last Objective-Swift post. The inheritance mechanism in ObjS is prototypical, meaning that an object inherits from a single other object rather than getting its behaviour from a class. … Continue reading

This gist shows the result of doing the self-threading talked about at the end of the last post. Each method implementation takes an object pointer and a selector name, just like in the real world. That’s enough Objective-Swift for me. … Continue reading
Further Advances in Objective-Swift
Previously on SICPers, I defined objects as functions that return methods and built dynamic method dispatch in this object system. It’s time to tie up some loose ends. Proper selectors In languages like Smalltalk and Objective-C, an object’s range isn’t … Continue reading
