Modifying Clang for a Safer, More Explicit C++

In plain words

Modified C++ is a customized version of the Clang compiler that implements safety and clarity improvements to C++. Rather than creating a new language, it modifies Clang directly to make C++ more explicit and less error-prone, inspired by research on language evolution. The project targets C++ developers who want to experiment with safer coding practices while maintaining compatibility with existing code through compiler flags and diagnostic pragmas.

In the maker’s words, at launch

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…

  I built a small browser engine from scratch in C++Jan 2026 · github.com · ▲146

  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…

  C3 – A C alternative that looks like C2022 · ▲182

  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…

  Pornpen.ai – AI-Generated Porn▲711

  Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results. For comments/suggestions/feedback please visit…
