About classes

slide-15
SLIDE 15

Class definition explosion

  • subclass:, variableSubclass:, variableByte.. variableWord, weak:
  • uses:
  • layout:
  • tag:
  • immediate:, ephemeron
  • category:
  • package:
  • slot:
  • instanceVariableNames:, classVariableNames:
slide-16
SLIDE 16

Need a fluid API

  • Only specify what is used!
  • No empty classVariableNames: ‘’
  • Handling combinatorial explosion

Class <<< #Box vars: { #width . #height }; package: #MyPackage.

Possible Designs

Class { superclass: #MySuperclass; uses: #MyTrait; vars: { #a. #b }; classVars: { #A. #B }; package: #MyPackage; tags: #(Core). }

Class <<< #MyClass superclass: #MySuperclas; uses: #MyTrait; vars: { #a. #b }; classVars: { #A. #B }; package: #MyPackage; tags: #(Core)

Need a class **definition**

  • a.k.a. AST
  • traits, slots, kinds….
  • Can be manipulated
  • Support for Smart Suggestions
  • Need to be able to have **undefined** classes
  • Important for modules!
slide-19
SLIDE 19

Working on a “ClassParser” + Nodes

  • Can handle variations, backward compatibles….
  • Support for smart suggestion in class definition
  • Avoid ‘*subclass:*’ matches: str

Opal

  • Warnings into real objects
  • Another pass on the API
