Nested Class Modularity in Squeak/Smalltalk
Springer, Nested Class Modularity in Squeak/Smalltalk Nested Class Modularity in Squeak/Smalltalk Modularität mit geschachtelten Klassen in Squeak/Smalltalk by Matthias Springer A thesis submitted to the Hasso Plattner Institute at the University of Potsdam, Germany in partial fulfillment of the requirements for the degree of Master of Science in ITSystems Engineering Supervisor Prof. Dr. Robert Hirschfeld Software Architecture Group Hasso Plattner Institute University of Potsdam, Germany August 17, 2015 Abstract We present the concept, the implementation, and an evaluation of Matriona, a module system for and written in Squeak/Smalltalk. Matriona is inspired by Newspeak and based on class nesting: classes are members of other classes, similarly to class instance variables. Top-level classes (modules) are globals and nested classes can be accessed using message sends to the corresponding enclosing class. Class nesting effec- tively establishes a global and hierarchical namespace, and allows for modular decomposition, resulting in better understandability, if applied properly. Classes can be parameterized, allowing for external configuration of classes, a form of dependency management. Furthermore, parameterized classes go hand in hand with mixin modularity. Mixins are a form of inter-class code reuse and based on single inheritance. We show how Matriona can be used to solve the problem of duplicate classes in different modules, to provide a versioning and dependency management mech- anism, and to improve understandability through hierarchical decomposition. v Zusammenfassung Diese Arbeit beschreibt das Konzept, die Implementierung und die Evaluierung von Matriona, einem Modulsystem für und entwickelt in Squeak/Smalltalk. Ma- triona ist an Newspeak angelehnt und basiert auf geschachtelten Klassen: Klassen, die, wie zum Beispiel auch klassenseitige Instanzvariablen, zu anderen Klassen gehören. -

ESUG 2012 Report
CS21 and ESUG 23, Brescia, July 13th - 17th, 2015 1 CS21 and ESUG 23, Brescia, July 13th - 17th, 2015 This document contains my report of the ESUG conference in Brescia, July 13th - 17th, 2015 (and brief remarks on the Camp Smalltalk on the Sunday before it). As there were parallel tracks, I could not attend all talks. At the end, I also report a 2015 UK Smalltalk User Group meeting I attended. Style ‘I’ or ‘my’ refers to Niall Ross; speakers (other than myself) are referred to by name or in the third person. A question asked in or after a talk is prefixed by ‘Q.’ (sometimes I name the questioner; often I was too busy noting their question). A question not beginning with ‘Q.’ is a rhetorical question asked by the speaker (or is just my way of summarising their meaning). Author’s Disclaimer and Acknowledgements These reports give my personal view. No view of any other person or organisation with which I am connected is expressed or implied. The talk descriptions were typed while I was trying to keep up with and understand what the speakers were saying, so may contain errors of fact or clarity. I apologise for any inaccuracies, and to any participants whose names or affiliations I failed to note down. If anyone spots errors or omissions, email me and corrections may be made. My thanks to the conference organisers and the speakers whose work gave me something to report. My own talk is written up at much greater length than the others. Venue The accommodation was in old town of Brescia (called Brixia in Roman times). -
