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.)

I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…

Get it from here: https://github.com/c3lang/c3c In 2019, while contributing to the C2 language, I started up "C3" as a pet project while waiting for pull requests to be approved... Now it's 6 years later and C3 well on its way to 1.0, having released 0.7.0 last week. Unlike other C alternatives, C3 tries to evolve C – but without concern to backwards compatibility to the latter. What it adds to C is among other things: - Module system - Semantic macros and compile time introspection - Lightweight generic modules - Zero overhead errors - Build-in slices and SIMD types -…

Inspired by Compiler Explorer and other playground/fiddle websites like jsfiddle, db-fiddle, Go playground, and Rust playground, I thought it would be cool to have a playground for nearly any program so I've been working on Program Explorer: a playground for running programs from containers. I am inspired by these playgrounds because they are great educational tools for quickly experimenting and as communication tools by sharing shortlinks that reproduce bugs for instance. I would love for every open source project that publishes a container to get their own playground for free. I'm…

I recently dug up an old project in an attempt to improve on it. It's a code sandbox for playing around with HTMX in the browser, that runs a mock server within the sandbox iframe. The server "framework" is loosely based on Django, so if you're familiar with Django, you'll immediately understand what's going on. I recommend clicking through the examples. Github repo: https://github.com/lassebomh/htmx-playground Probably my favorite part is the lack of HTMX specific code. It's designed to mimic the client and server, but really nothing else. In principle, this means that…

Hi HN! My team at Efficient Computer (https://efficient.computer) and I are working on a new computer architecture and I am leading the team that is building the compiler for our chip. Our hardware is focused on energy-constrained embedded applications and is super efficient, which lets devices run for years on a small (ie AA) battery. We built a playground for our compiler that has a cool visualizer and debugger that shows how your C code (more languages to come) maps to our Fabric architecture, and an energy model that shows you how much less energy your code uses on our…

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.

Compiler link: https://github.com/c3lang/c3c Docs: http://www.c3-lang.org This is my follow-up "Show HN" from roughly a year ago (https://news.ycombinator.com/item?id=27876570). Since then the language design has evolved and the compiler has gotten much more solid. Assorted extra info: - The C3 name is a homage to the C2 language project (http://c2lang.org) which it was originally inspired by. - Although C3 mostly conforms to C syntax, the most obvious change is requiring `fn` in front of the functions. This is to simplify searching for…

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…

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"…
