   Clx – Compile Lua to Native Executables Through C++20▲143

   Hi HN, clx is an ahead-of-time compiler for standard Lua that generates C++20 and produces standalone native executables through GCC, Clang or MSVC. The project started as an experiment to see whether modern C++ could be used as a portable compiler backend instead of LLVM or direct machine code generation. The generated code is then compiled and optimized by the host toolchain. The latest release replaces the previous NaN-tagged value representation with a new shadow-types implementation, adds full int64 support, improves native arithmetic code generation and adds ARM64 macOS coroutine…

    Going into freshman year, figured I should build an interpreter▲138

    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

    I created a language called AntiLang – breaking all the conventions▲143

    AntiLang is an interpreted programming language written in Go. The basic idea of this is to keep all the logical parts of a language same, but reverse the structure of it. The idea for this project came when I was having a long midnight conversation with my friend and thought of writing such a weird language. The initial draft was far worse than the current implementation; we thought of reversing the brackets and the language would be read from bottom to top. I'm happy that I dropped that idea Technical details: As the interpreter is written in Golang, I compiled it to WASM, and the whole…

    Paseo – Beautiful open-source coding agent interface▲92

    Hey HN, I'm Mo. I've been building Paseo, an open source environment for running Claude Code, Codex, and OpenCode across desktop, mobile, web, and CLI. It started last September as a push-to-talk voice interface for Claude Code. I wanted to talk to an agent while going on walks. Then I wanted to see what it was doing. Then text it when I couldn't talk. Then review diffs, run multiple agents, and manage work across machines. After a lot of iteration, it turned into a broader environment. The basic model is: - A daemon runs on your machine (MacBook, desktop, VPS, etc.). - Clients connect to it…
