Opening an Object Explorer - LucPrestin/Hidden-Modularity GitHub Wiki
Description
This scenario is about tracing the drawing of the explorer, one of the most important tools in Squeak. To do this, we create a nested dictionary as the object to be inspected. We then explore this dictionary.
Code
| tmp |
tmp := Dictionary new.
tmp at: '1' put: 1.
tmp at: '2' put: Dictionary new.
(tmp at: '2') at: '1' put: 1.
(tmp at: '2') at: '2' put: 'Hello'.
(tmp at: '2') at: '3' put: Morph new.
