#objectoriented — Public Fediverse posts

@badrihippo modern frameworks like React, Vue, and Van.js are all very similar, but I have not seen a consistent name for this family of frameworks. I have heard it called “The Elm Architecture,” because they are loosely based on how the Elm programming language originally did GUI programming in the browser. I have also heard it called the Model-View-Update paradigm. But most people just call it “React-like” or “Reactive Programming” because they are all similar to the very popular “React.js” framework.

Note that this should not be confused with Functional Reactive Programming (FRP), although the two are not completely different. As I understand it, React-like GUIs and FRP can both be implemented on top of a more powerful and more general computation model called “propagators” (here is the PDF of the original Propagators paper).

@dthompson wrote a really good blog post about FRP, propagators, and React-like frameworks.

I hope that helps, but I am not as well-versed in the theory of this stuff as I should be.

Oh, and I should say, before React-like took over the world wide web, GUI programming was mostly intertwined with Object Oriented Programming and design, so a good place to start might be to read up on Smalltalk OOP and GUI design.

A category is formally defined as being a group of one or more classes.

Have you heard of this use of "category" before? If so, in which context/language/compiler?

EDIT: For context, from the #Psion SIBO C SDK's Object Oriented Programming Guide:

A category is formally defined as being a group of one or more classes. The classes are packaged into a load module which, when loaded, occupies a single code segment. A code segment may not contain more than one category. There is, therefore, a one-to-one correspondence between a category and the executable code in a single code segment. Note that this implies that an application that occupies a single code segment may not contain more than one category.

@chakie #Python #ObjectOriented
Question.
I have written #PySide classes to implement editable multi-segment lines for both straight lines and hermite splines. The interfaces are identical, barring the spline constructor, which takes a tangent list.
I want to create a parent class `PolyLine` which can either be `straight` or `hermite`. A "Strategy Pattern" _seems_ to be the solution, but it feels complex. Putting an `if` into every method feels worse.
Ideas?

OOP Review: We are all all inherited from fish right?

#programming #science #scishow #hankgreen #oop #software #genetics #fish #teaching #objectoriented

Open Humanities Press has published a 2nd edition of Timothy Morton's Realist Magic: Objects, Ontology, Causality. Comes complete with a new preface by Morton.

Like all OHP books, Realist Magic is available open access:

https://www.openhumanitiespress.org/books/titles/realist-magic-2nd-ed/

Book description

#ObjectOriented ontology offers a startlingly fresh way to think about causality that takes into account developments in #physics since 1900. Causality, argues Object Oriented Ontology (OOO), is #aesthetic. In this book, Timothy Morton explores what it means to say that a thing has come into being, that it is persisting, and that it has ended. Drawing from examples in #physics, #biology, #ecology, #art, #literature and #music, Morton demonstrates the counterintuitive yet elegant explanatory power of OOO for thinking causality.

#philosophy #theory

The book is published as part of the New Metaphysics series:

Loglan'82: programming language for object-oriented and distributed programming

I've hit upon a new kind of Liskov Substitution Principle in #Programming.

"If I substitute Barabara Liskov for myself, right here in this chair, do I still call this cruft, and the language it is written in, #ObjectOriented ?"

I’m currently reading Extreme Programming Explained 2e (Beck et. al), Object Thinking (West), and Object-Oriented Analysis and Design With Applications 3e (Booch et. al). The contrast between OT and OOADwA is startling. OT got me reading eXPE, and I regret not reading it sooner. Am I destined to say that about every Beck book I read?

May I just say so myself that I‘m loving playing with Kitten¹ to build Domain² (shown below) and Place³.

#Kitten #Domain #Place #SmallWeb #SmallTech #humanRights #democracy #technology #peerToPeer #peerToPeerWeb #web #dev #JavaScript #HTML #CSS #NodeJS #htmx #WebSocket #objectOriented #eventBased #hypermedia

Little preview video: Kitten’s improved component model

• Class-based page routes and components
• Object-oriented
• Event-based
• Seamless hypermedia-driven WebSocket-based event mapping and interface updates (Streaming HTML)
• A light server-side live component hierarchy with event bubbling
• Almost as if you’re building a desktop or mobile app instead of a web app…

… another authoring simplification made possible because on the Small Web – which is a peer-to-peer web – you build a web app/site as a tool for one person (the owner of the site/app) instead of as a tool for you to farm millions of people.

… still experimental ;)

Pretty soon, you’re going to be able to view your live pages and the events on them in real time while developing Kitten apps.

The improved component model with support for class-based routes (and a server-side component hiearchy that lets you build well-encapsulated components and pages and work in an event-driven way) is coming along nicely and I’m back to writing Place¹ using it.

(In the GIF, you’re looking at Place’s profile settings page. Not shown here but those profile changes reflect in realtime on all open pages. The highlighted piece of code is what streams the event details to the browser.)

REPOST (JAN 2024): My first thoughts on #Psion's dialect of Object Oriented C for the Series 3 and related portable computers.

Includes the JPI/Clarion #TopSpeed #compiler, a proprietary preprocessor, the Eiffel programming language, and a handful of calling conventions.

Also, did somebody say Objective-C?

Firing up #Inform7 on my #Mac to write another #interactiveFiction #game. Getting stuck into the prologue. This will be a much bigger game than I've written before, including 7 main sections in the #code. It is going to take some time. So best get on with it sooner rather than later!

In the DES examples I have seen, the style of programming looks similar to microcontroller event handling code.

I've spent a long time writing object oriented code and find difficult to follow event driven code.

I have a question for people with better theoretical background on #ObjectOriented #programming and especially for #CPlusPlus developers.

#askFedi #fediHelp Is the following pattern known and does it have a name?

I have a number of classes (call them C1, C2, etc) that all derive from the same class B. I have a superclass (template, actually) D that derives from C1, C2 etc. To have a single B, the standard solution is to go with virtual inheritance to close the diamond (so far, so good).

1/n

The things that come to mind when hearing these three letters are cars, inheritance, getters, setters, and ObjectFactoryFactorySingleton.

A summary of my first impressions of #Psion's object oriented ecosystem for #EPOC16.

TL;DR: It feels janky, but I'm also a noob. Plus what about Objective-C?

I've been a proponent of starting with the user scenario or business problem first for decades now. I think that can take the form of storyboarding, or business process documentation. Those activities (imo) always lead to domain object modeling next, and figuring out the data mapping later.

This article **Mark Seemann** does a nice job describing how and why this is a good idea.

Some #RealTime #ObjectOriented programming in #ATS for #RosettaCode. And I mean really #OO, not type hierarchy masquerading as OO. Communicating objects.

There is no type hierarchy, because none is needed. One can use a closure to connect two objects, as long as the connection is compatible at both ends.

And there is just one thread, because why in heck would you need two threads, just to read the time on the clock??????

#Currying in #FunctionalProgramming is a way to temporarily retain a value for later use. The value is retained in a new, scoped function instance.

Wait.

What?

Isn't that quite similar to what the #ObjectOriented #Java #programmingLanguage does when it retains a value in a Class instance, for later use?

Yes.

Yes, it is.

And that makes currying feel like cheating. Which makes #FP languages that allow it, feel like a hack.

So, what else is there? #Memoization?

Over on Reddit I'm participating in a discussion about code smells. Invariably, the number of lines in a method and the number of methods in a class are mentioned.
