OOP in Pure C

Very nice! Reminds me of an article on Quora on "Object-Oriented Programming in C: A Deep Dive" by Khanno Mikhail: "...there are actually THREE ways to accomplish OOP in C (aptly named): Open style. Pointer style. and GTK style (GObject style). There are also three ways to apply function/method polymorphism in C as well: Struct style. Disjoint style. and Interface style ..."

BREAKING NEWS: c programmer discovers dynamic dispatch in the lord's year 2024

[@Daniel_Zhu_a6f]

Tsoding worked as a java programmer afaik. btw, most powerful dispatching i've seen was in languages that are not traditionally considered as oop ones (julia, some ML family languages), since it could dispatch on multiple arguments and switch between runtime and compile time.

A very interesting idea and quite elegant implementation! It's rather amazing that hot reloading can work so well in a typed and compiled language like C that doesn't have much features. I wish modern languages put some thought on making this a feature because it is so convenient for creating web servers, gui's and other highly interactive and visual applications.

​@@СергейФёдоров-щ8ш Maybe, just maybe, it's because in a stream, the streamer talks with the chat, and reads it, and people recommend him to do X or Y and he tells why yes or why not to do it that way, and if you can't read that then it makes no sense? Just saying

[@asakhar]

Tsoding, you don't actually need a dynamic array for vtable, or even register it at runtime, just store it in global library plain array variable and define it inplace. This way "dynamicness" is achieved through loading the lib itself, you just recompile the lib itself and vtable gets reloaded, then you just resolve it like you already do with function symbols. This way you can add vtable entries, but can't reorder or delete stuff from that just like in your implementation. I can provide an example via PR but unfortunately can't find public repo of panim, please consider making it public so people like me can f around with it)

[@chri-k]

That's actually a very good idea

[@neshkeev]

It only makes sense to define the Task struct's function members to accept Task itself so it looks similar to `self` in Python and besides you can call other task's functions from a Task's function

[@Daniel_Zhu_a6f]

did you know that in python you can assign free functions to a class and they will become methods? it also works in reverse, you can assign methods of a python class to variables to circumvent runtime dispatching when calling methods, like this: ``` class A: def f1(self): print('A') class B(A): def f1(self): print('B') f1 = A.f1; b = B() b.f1() # prints 'B' f1(b) # prints 'A' ```

[@shakkar23]

For the tag implementation, you can make the tag an enum, as well as make the data a union of pointers to the types that inherit it, this allows the vtable to be off of the heap as you now know the size in compile time, as well as you can use designated initializers to have a more well defined offset of all of the pointers for your vtable.

[@DVRC]

Looking at old codebases I've seen many cases of OOP in C: - Sun Pixrect is a low level library for drawing on the framebuffer, and for each framebuffer there is a different implementation. At the creation of a Pixrect object, it is dispatched with the function table to manipulate it - Still from Sun, X/NeWS has a graphics library called Shapes, that replaced the CScript (the PostScript graphic layer) + Pixrect combo, and it has plenty of macros to declare classes in C and dispatch all the methods. This package handles shapes, paths and framebuffers - At CMU, a preprocessor called "Class" was made for the Andrew project. It enriched C with Object-Oriented specific syntax (similar but different from both C++ and Objective C). I guess this was used for the Andrew Toolkit and other applications of the suite

[@snowcrash-]

I love your content dude it's just so good.

[@AloisMahdal]

A huge problem with OOP is that virtually all basic tutorials go right away into stuff like inheritance and abstract classes, but in reality you should avoid that as much as possible (use interfaces and composition in 99% of cases). Then there's a ton of stuff such as composition, solid and "OOP design patterns" and *some* part of Clean Code... Lot of it is actually useful and applicable to most languages, OOP or not.

"You can do anything in C" - Since (almost) everything is made in C, I guess you are right. hahaha If there are programming structures that are not available in C, one can write his/her own programming language in C, and call it something like "Python"," Ruby", "C++" or "Perl" - This is how it has been done since 1972. At the end stands (almost) always C.

[@bbq1423]

The boilerplate in C for the animal example could have been a bit smaller if you would have stuck to what C++ does a bit closer. In C++ it would inline the dog and cat data into the same allocation as for animal, meaning Animal effectively becomes a "Animal_Methods**" with some extra data to the right of it. Dog and Cat would also need the vtable pointer in the struct definitions, but this could be mitigated via the use of the butterfly technique in the utility methods. Initialization code for the tags could also be simplified if you used the C++ approach.

[@NotherPleb]

Well, a understand where the gatekeeping accusations come from. When people ask that kind of stuff it's not like they don't know how to search on the internet, it's more what to search, they want some advice about where to start looking because they are overwhelmed. They want a good root concept that branches to other concepts to learn, if you start at a leaf it's confusing, and often you find your way up to the root yourself, but it takes more time and it's more painful. I guess they can search for that advice on the internet too, but if they come to you it's because they trust your advice.

[@SeishukuS12]

I played around with something similar a number of years ago, it's kinda fun... Not *super* practical, but fun. Though these days, I do still kind of lay out my data and functions in a similar manner, just without the "virtual functions"/function pointers... So if I ever become unlazy, I can just toss everything into classes and be with the hipsters and use C++. :D

[@kibels894]

Could you also solve it by getting the arena from the main executable's memory space? Or does that only ensure the pointers aren't unreachable, but they will still be garbage after reloading?

Honestly, at this point it's kind of scary how similar my data structures library was to your OO in C code. Also, quite similar to the code I would hand students that asked for homework help in the chat room I frequented. For some reason, they were constantly asking for help with linked lists. So I wrote a joke implementation which perfectly demonstrated the concept and worked without any errors but was a giant stream of FOAD's in various forms and at one point even had a little poem. I really miss Yahoo chat rooms. Those were some of the best times I spent online. Even found a really awesome MUD through various people back then. I really wish I could remember the address or name of it because it was an amazingly detailed MUD that allowed you to dismember your enemies and even cook their bits over a fire. Who knows, maybe I'll write one myself. As to the original subject, I think you should write a proper animations programming language and implement a VM to run it. I already know you won't, but I think you should.

I have full control of what languages I use, what paradigms I use, etc. And OOP is not click-bait; it is a very logical way to program, creating analogies from the real world of objects that have properties and actions or methods. I didn't watch the whole podcast, but if you wanted to write your squares as OOP, The squares would contain their own position on the screen, and expose methods like Move(x,y) Color(color) and whatever else you'd want to do with them.
