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 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

Hey HN, I wanted to share the new online playground for Salt (https://salt-lang.dev/playground/), a sovereign systems language designed for high-performance, distributed workloads where paying an "abstraction tax" is no longer acceptable. We started building Salt to bridge the gap between the raw power of manual pointer arithmetic and the safety guarantees of modern high-level languages. The architecture relies on an MLIR-based backbone and a Z3-powered "formal shadow," and the design is rooted in three main pillars: Fast Enough: The target is to stay within 20% of C's…

Everything that would be here is in the README. I hope this gets big, it has tons of potential.

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…

Onboard-CLI—a blazing-fast developer tool I built in Go. It uses AST parsing (Tree-sitter) to map out codebase architecture and automatically blocks spaghetti code and bad dependencies locally before you even commit. I heavily optimized the concurrency, so it can parse 50k+ files in under 10 seconds.

Hey everyone! I just launched Essentials-C, a minimal C library with handy functions for string and array manipulation – built from scratch with simplicity and learning in mind. Highlights: - `length`, `reverse`, `substring`, `trim`, `replaceChar`, etc. - `bubbleSort`, `includes`, `startsWith`, `endsWith`, and more - Pure C, no external dependencies - Clean, readable code – great for beginners and power users I’m building it to be the “Essentials” of every C project — feel free to contribute or suggest features! GitHub: https://github.com/oileo/Essentials-C Feedback is…

This is my hobby C compiler project. Decided to publish the code today, as it finally compiled itself. The readme on the linked GitHub page has a bit of information on how it works. I wrote the thing for fun, but if anyone gets a better understanding of the dark corners of C because of it, I am happy.
