Products that do what Hacking C++ to support Structure of Arrays does
Using my very primitive abilities with template metaprogramming, I put together a structure of arrays (SOA) class for C++. The point of SOA is that it can be cache friendlier.

Hello Hacker News. I’m Martin, a graduate student from Prague, and I’ve been working on Coros, a C++ library for task-based parallelism. After spending some time with OpenMP and oneTBB, I wanted to try building a library using modern features from the C++ standard library. I’ve used coroutines for task encapsulation and C++23 expected for exception handling, while trying to maintain good performance. Additionally, I’ve implemented monadic-like behavior to allow easy chaining of tasks, similar to the monadic operations in std::expected. You can check out the project here:…

Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

Hi HN! Korean high school senior here, about to start CS in college. I built a browser engine from scratch in C++ to understand how browsers work. First time using C++, 8 weeks of development, lots of debugging—but it works! Features: - HTML parsing with error correction - CSS cascade and inheritance - Block/inline layout engine - Async image loading + caching - Link navigation + history Hardest parts: - String parsing(html, css) - Rendering - Image Caching & Layout Reflowing What I learned (beyond code): - Systematic debugging is crucial - Ship with known bugs rather than chase…

Back then there were not a lot of frameworks for C++ like there are available now, gradually added serialization, reflection, orm, modules for apache|nginx, then started adding programming language integration and then finally added support for building on various Os'es and also support for most of the build tools out there.

I love C and C++, but setting up projects can sometimes be a pain. Every time I wanted to start something new I'd spend the first hour writing CMakeLists.txt, figuring out find_package, copying boilerplate from my last project, and googling why my library isn't linking. By the time the project was actually set up I'd lost all momentum. So, I built Craft - a lightweight build and workflow tool for C and C++. Instead of writing CMake, your project configuration goes in a simple craft.toml: [project] name = "my_app" version = "0.1.0" language = "c" c_standard = 99 [build] type = "executable"…

A little help for programmers, who wants to run C/C++ code in the browser. (This is my second attempt to show it, first time I got banned bcoz of my personal page domain, I don't really understand it why is is suspicious.)

Since there is so much interest on HN in floats lately and their software implementations, I wanted to show mine. It has no use and is just for teaching me floats and C++. Give me your thoughts.

Modified C++ Inspired by the paper "Some Were Meant for C" by Stephen Kell, I decided to show that it's possible to iterate C++ to be safer, more explicit, and less error-prone. Here's a possible starting point: I didn't invent a new language or compiler, but took the world's best compiler, clang, and modified it to begin iterating towards a new furture of C++. Naming things is hard, so I call this 'Modified C++'. Some of the following could be implemented as tooling in a linter or checker, but the idea is to update the compiler directly. I also wanted to learn more about clang. This…

This project presents a new data structure for storing ordered integer maps. The proposed data structure is a compressive, cache-friendly, radix tree that has performance comparable to an unordered map (`std::unordered_map`) and is an order of magnitude faster than an ordered map (`std::map`).

Hi all! I'm going into my freshman year, and figured that the best way to prepare for the intro to programming Racket course would be to implement my own garbage-collected, dynamically typed, functional programming language in C ;) Anyways... here's the repo: https://github.com/liam-ilan/crumb I started learning C over the summer, so I still have a whole lot to learn... Any feedback would be greatly appreciated! :D

While helping one of my students create and iterate on a game in C using raylib, I realized there was quite a lot of time spent on experimenting with level design and colors, how the player moves, gravity, etc. and a lot of time was wasted making a change, exiting the game, recompiling, running the game, deciding his change wasn't right, and going through the whole cycle over and over. I could tell it was demotivating, and this process was creating a barrier that prevented him from experimenting to his heart's content. I started this project to solve this problem by giving a simple gui to a…

Hi HN! I've built [CXXStateTree](https://github.com/ZigRazor/CXXStateTree), a modern C++ header-only library to create hierarchical state machines with clean, intuitive APIs. It supports: - Deeply nested states - Entry/exit handlers - State transitions with guards and actions - Asynchronous transitions with `co_await` (C++20 coroutines) - Optional runtime type identification for flexibility It's ideal for complex control logic, embedded systems, games, robotics, and anywhere you'd use a finite state machine. I’d love feedback, use cases, or contributions from the…

Yes, this includes the MBR and partition boot sector. The partition table is modeled as a class hierarchy. Second stage loads a kernel from a FAT32 file. I'm normally a C programmer, but for a work project, I recently revisited C++, a language that I had an on-again-off-again relationship over the years. I did this as a fun training exercise on the side to get familiar with the language again, but obsessed a bit and kind of overshot the target. I thought the result might be of interest to someone.

Morning HN. Random number generation feels is a somewhat underrepresented topic in the C++ realm. There is a lot of questionable info about it found online and even the standard library is quite behind the times in terms of it's algorithms. It suffers from trying to accommodate sometimes impractical standard requirements and has several ways of getting significantly bad statistical results. This leaves a lot easily achievable performance & quality on the table. So, being a mathematician who mostly works with stochastic models and wants these models to run fast and well, I embarked on a…

This weekend I created stacklib.h - a single-header library that brings Forth-style stack operations to C. It implements a basic interpreter with: - Stack operations (push/pop/dup/swap/over/drop) - Arithmetic (+, -, *, /) - Output (., emit, cr) - Stack inspection (.s, depth) Example usage: Stack s; stack_init(&s); dict_init(); exec(&s, "10 20 + ."); // Prints "30" exec(&s, "1 2 3 4 .s"); // Shows stack contents The library is self-contained, requires no dependencies, and handles basic error checking. It was inspired by wanting to understand…
