Han – A Korean programming language written in Rust
A few weeks ago I saw a post about someone converting an entire C++ codebase to Rust using AI in under two weeks. That inspired me — if AI can rewrite a whole language stack that fast, I wanted to try building a programming language from scratch with AI assistance. I've also been noticing growing global interest in Korean language and culture, and I wondered: what would a programming language look like if every keyword was in Hangul (the Korean writing system)? Han is the result. It's a statically-typed language written in Rust with a full compiler pipeline (lexer → parser → AST →…
Han – A Korean programming language written in Rust launched on March 14, 2026 with 208 votes, #152 of 23,380 launches that month and more than 99% of that year's launches.
In plain words
Han is a statically-typed programming language written in Rust where all keywords use Hangul, the Korean writing system. Built with AI assistance, it includes a complete compiler pipeline with lexer, parser, AST processing, and both interpreter and LLVM IR codegen. The language supports arrays, structs, closures, pattern matching, exception handling, file I/O, module imports, a REPL, and a basic language server. Han is intended as a side project exploring language design rather than a practical replacement for existing languages.

ut – Rust based CLI utilities for devs and IT2025 · github.com · ▲170Hey HN, I find myself reaching for tools like it-tools.tech or other random sites every now and then during development or debugging. So, I built a toolkit with a sane and simple CLI interface for most of those tools. For the curious and lazy, at the moment, ut has tools for, - Encoding: base64 (encode, decode), url (encode, decode) - Hashing: md5, sha1, sha224, sha256, sha384, sha512 - Data Generation: uuid (v1, v3, v4, v5), token, lorem, random - Text Processing: case (lower, upper, camel, title, constant, header, sentence, snake), pretty-print, diff - Development Tools: calc, json…

I'm making a dynamic language in Rust2022 · github.com · ▲184An implementation of a dynamic programming language in Rust. Includes: Parser/Compiler, REPL, Virtual Machine, Bytecode Disassembler This started out as a learning project to teach myself Rust. It has grown into a decently substantial piece of software and I've learned quite a bit in the process! Some neat things: + A garbage collector that can store dynamically sized types without any double-indirection (i.e. I have my own Box implementation with manual alloc/dealloc) + The smart pointer used to reference GCed data is a thin pointer. The ptr metadata needed for DSTs is stored in…
A small programming language where everything is pass-by-valueJan 2026 · github.com · ▲91This is a hobby project of mine that I started a few years ago to learn about programming language implementation. It was created 95% without AI, although a few recent commits include code from Gemini CLI. I started out following Crafting Interpreters, but gradually branched off that until I had almost nothing left in common. Tech stack: Rust, Cranelift (JIT compilation), LALRPOP (parser). Original title: "A small programming language where everything is a value" (edited based on comments)
The Sage Programming Language2024 · github.com · ▲114Sage is a Rust-like programming language built on a brainfuck-inspired VM with LLVM-like properties. https://github.com/adam-mcdaniel/sage Check out the web-demo to run the compiler in the browser, along with a graphical example using JavaScript interop! https://adam-mcdaniel.net/sage Sage is designed to be portable, but also useful. To prove its usefulness, I used it to implement a user-space for a new operating system: SageOS https://github.com/adam-mcdaniel/sage-os The language also runs on embedded devices, like the flipper zero!
Hancho – A simple and pleasant build system in ~500 lines of Python2024 · github.com · ▲162Hi HN, I've been taking a break from my big side projects to work on a smaller side project - a tiny build system that's based on what I've learned from using Ninja and ad-hoc Python for my homebrew build systems over the last few years. It's basically a promise-based dependency graph runner plus a simple text templating engine, and it works quite well for the smallish projects I've tried it out on so far. If you find Make crufty, CMake inconsistent, Ninja verbose, and Bazel just too much build system, give Hancho a try. Don't like one of Hancho's defaults? It's only 500 lines - hack it up…
