Products that do what Lreng – My small programming language written in C does

This is my side project for the past few months. I started it because I just learned about functional programming and at the same time want to write something cool in C. Web playground: https://leonw774.github.io/lreng

   Learn C and its lower levels interactively, in the browser▲356

   I made a simple virtual machine that runs C in the browser.This project is made as an experiment to see if C can be learned easier if the lower level is covered in paralel.

   Ink: An LLVM based programming language [WIP]▲6

   Hi there. I'm working on a programming language -- called Ink - in my spare time, with a friend. It uses LLVM for the backend, the parser and lexer are both hand written in C. The project is just for a bit of fun, we aren't trying to "revolutionize the programming language", but we're okay with being a bit quirky and out of the box with some of the syntax/features in the language. At the moment, the language is in it's early stages, and there's still a lot to do, which means that if you want to learn more about compilers, now would be a good time to start working on the language, since…

    Self Hosting C Compiler▲5

    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.

    First tutorial to date. Writing your first C program, includes a link at the bottom with a detailed look at printf() as optional reading. I would love some feedback, as I intend writing up a lot of dev articles for people to learn from : www.xanthu.com/first-c-program

    I rewrote the most common core string.h functions in pure C. I mostly did it to learn pointers and string. Would love to get any feedbacks:)

    Lisp in Five Days▲9

    Hi HN! I kept hearing about Lisp and why it was special but didn't have a great place to start. I wanted something self-contained that helped me develop intuition rather than fluency. My hope is this is helpful for casual programmers, professionals from other fields who interact with code, or engineers who haven't had much exposure to interpreters or compilers. Hope this helps anyone else who's curious about getting a sense of Lisp and what makes it special with a limited time investment! Feedback or other cool Lisp things welcome :)

    Built a tiny interpreter from scratch in C to understand how they work▲5

    Hi HN, I'm the author. I built this project for two simple reasons: I've always used higher-level languages and wanted to finally understand what's happening "under the hood" of an interpreter. I also wanted a real project to force me to "power up" my C skills, especially with manual memory management and reference counting. The result is ToyForth, a minimal interpreter for a Forth-like language, written from scratch in C, stack-based. I focused on making the code clean and understandable. It's broken down into a few simple parts: A parser that turns source text into a list of objects…

    G# –> a new dotnet language like Go/Swift/Kotlin with C# interop▲9

    I started working on this back in 2019, mostly as a design idea. Over the last month I made a big push to make it 100% usable and replace C# in all my personal projects. I now feel it's solid enough to gather feedback from other developers. If you take it for a spin, I hope you enjoy it and send your thoughts!
