Newb question: pattern to generate objects with common behavior
by xd3a9gsmwk＠liamekaens.com 04 Apr '24

04 Apr '24

I tried reading much of the Handbook to answer this very basic question, and didn't find it. How do Self programmers usually set up to be able to create at runtime a family of objects with shared behavior, more or less analogously to using a class and its `new` selector or operator in some other languages? I understand, I think, the basic semantics provided by the Self object system. But what are the usual programmer practices as to paths to get to the relevant parts for the equivalent of a class? I suppose you might have a prototype object and a traits object, and your equivalent of `new` would be to ask the prototype object to clone itself, which gives you a shallow copy, right?

Making Objects From Patterns

I am working in another language, but I want to learn from the viewpoint of Self enthusiasts. On Reddit, I said: In object-oriented programming, for most engineering benefit, is it better for client code to have to distinguish between cloning a prototype and instantiating a class? Or should I be able to pass to the client code an object that could be either a prototype or a class, so the client code could request a same-named operation in either event, and the result would be a clone or an instance? And if so, should the operation be called "clone", "new", "create", "make", or something else?

UKSTUG Meeting - Maximiliano Tabacman: Electronic Roleplaying Assistant - 27 March 2024
by Giovanni Corriga 19 Mar '24

19 Mar '24

In this presentation, Maximiliano Tabacman will be presenting the main features, abstractions and design decisions behind ERA, the Electronic Roleplaying Assistant ( https://preview.drivethrurpg.com/en/product/137825/ERA-for-Rolemaster ). ERA is currently being used to create characters and manage the adventures of many gaming groups across the world, supporting Navigator RPG, Against the Darkmaster, Rolemaster Classic, Rolemaster Fantasy and Rolemaster Unified. We will review how Pharo allows creating a deployed version that runs locally in Linux, Mac and Windows, while Digital Ocean and Auth0 allow running an online server with different user roles. https://pharo.org/success/RolPlayingAssistant.html We will also mention how ERA makes use of the different frameworks developed and maintained by the Buenos Aires Smalltalk group, hosted at Github. Maximiliano Tabacman ( https://www.linkedin.com/in/maximiliano-tabacman-9aa4b817b/ ) is a long time Smalltalker with a Phd from the University of Buenos Aires. He is a Software architect at Mercap, executive secretary at FAST and creator of ERA. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/299364517/ ) to receive the meeting details. Don’t forget to bring your laptop and drinks!
