Products that do what Topaz – A small application language that compiles through Rust does
Hi HN, I'm Matt, CTO at STUDIO HAZE in Seoul. I've wanted to build a programming language for twenty years, ever since Ruby got me wondering what a small language out of Korea might look like. Today I'm opening the repo for the first time, as Topaz v5.2. Topaz reads like Python or TypeScript, runs on a reference interpreter (topaz run), and builds a self-contained native binary by lowering to Rust, then handing off to the Rust toolchain (topaz build). function factorial(n: int) -> int { if n string { return "안녕하세요, {이름}님!" } print(인사하기("토파즈")) // 안녕하세요, 토파즈님! sql, sh, and path…

Hi HN! Silk is a project I began working on approximately six months ago without any prior experience or knowledge of compiler design, and it's been a frustrating but fun learning experience. It is very much a work in progress, but I would love to hear feedback of any kind!

Hello HN! As a long-time professional Rust developer. I've always been frustrated by the difficulty and "hackiness" of producing bindings to other languages, whether a frontend, an FFI library, etc. Not just in Rust but in any language. After many years of trying existing solutions and trying to make my own, I've finally developed a solution I'm very happy with. RTK (aka Rust Type Kit) allows you to write Lua scripts that perform queries on your code, such as method calls to Axum's `.route`, function definitions, and more, and then receive rich type information including all argument types,…

Hey HN! I really like local apps for their simplicity and privacy and hate paying Saas bills and I wanted a way to start automating my life with AI so I started building Anything. Anything is built on Tauri so the front end is React and the "backend" is Rust. It's 100% local & 100% doesn't ask you to spin up docker to use. Another core goal of the app is to get away from "package bloat" you see in other general purpose AI oss projects where they have a package.json that is 300 lines long ( more on that later. ) Oh btw I suck at Rust! I learned Rust while building this so the code is _not…

Hi HN, I'm new to Rust and, after half of `The Rust Programming Language` I decided to delve into a project I would actually use: a markdown to html compiler that actually serves my micro-blog (I started just right after publishing the project hehe). The project is intentionally small and one-file contained: I wanted to have the full picture in mind. I'm open to comments, suggestions and PRs. If you asked me more convincing arguments to "why did you do it?" rather than "to learn Rust" I would respond with: LLMs are effectively a new type of web users today and will be more and more present…

I personally haven't event used or looked at Rust so I don't have an opinion. So now I'm interested hearing what others think? I think the syntax of Rust isn't very appealing, but that's not a good reason to /not/ look at it. Convince me? :)

I built LunarBasic because I wanted a modern recreation of BlitzBasic from back in the day. I wanted it to have good step debugging features, and I wanted it to compile down to a native binary with no external dependencies. I do know there's an open source BlitzBasic out there but I wanted something simpler and more concise. It does have a "pro" feature set, but for the foreseeable future, anyone joining up will have the pro version in perpetuity (eg I'm not trying to sell anything here). It's early (v0.8.0). Would love feedback on the language design and compiler output, especially from…

I'm excited to share "take 2" of the Prela query language. After sharing the previous version here, I've received some valuable feedback, the main one being the weird unicode-based syntax throwing people off. Prela now has a more familiar SQL-like syntax while adhering to the algebraic principle, which makes the language compositional and controllable, all the while keeping the core engine under 1k lines of code. The engine has also been rewritten from Julia to Rust, resulting in both simpler code and faster performance (not just because "Rust fast Julia slow", but for some pretty deep…

Link: https://docs.trysoma.ai/ For the past ~9 months I’ve been building Soma, an open-source AI agent & workflow runtime written in Rust, with a TypeScript SDK (Python coming soon). It’s not a framework; it’s meant to sit underneath whatever agent/tooling code you already write (Vercel AI SDK, LangChain, custom code, etc.). It provides features around your framework + a better DX for building agents. I’ve tried to take a Next.JS model: open-source, good DX, self-deployable. I originally set out to build a vertical back-office/operations product for SMEs. I needed a…

Hey HN, my name is Tom and I'm the founder of Svix. We've been working on Diom (https://diom.com) for the last 6 months, and I'm excited to finally share it on HN! Diom is a single Rust binary that replaces Redis, RabbitMQ, Kafka, and a lot of custom code for many common use-cases. It's open-source, self-contained, and has no external runtime dependencies. While building Svix, we had to reimplement the same backend primitives that everyone reimplements when building a service: robust caching, rate-limiting, idempotency, and more. We also constantly felt the tension between building…

Code review is the new bottleneck. "Tests passing" is no longer sufficient to trust the changes, and the (human) cost of evaluating the quality and robustness of new agent-written contributions is skyrocketing. We built Topos to evaluate code quality based on the structural properties of the programs themselves. We map your files to graphs (AST, CFG, CPG, MDG) and calculate metrics that can characterize how simple, composable, or secure your programs are. Agents can use this tool as they write and optimize based on your preferences. And yes, the inspiration for the repository is from…

I've implemented a `pl/0 compiler` in `rust-lang` to fulfill the curriculum design for `Principles of Compiler Design` in my college (NUAA, China). Here's the GitHub repository url: https://github.com/DrEden33773/pl_0 As far as I know, `Rust` is not well adpated (even known) by college students around the world. So, this project is to prove that it's totally possible to design a complete & usable project in Rust for a beginner. This implementation has a complete error handling strategy, which means it could find as many errors as possible in one run, instead of being…

Hi, over the past few months I've been working on this project: Numax is a small Rust runtime that does three things: it runs WebAssembly modules in a sandbox, has a built-in local key-value store, and syncs everything across nodes with CRDTs and gossip. Basically, you write a wasm module, run it on two machines, and they converge (I hope !). It's a decentralized system... I hope someone finds it interesting! There's a whitepaper I've put a lot into, and I think the code isn't bad either! I believe there's still room in this world for software that's fun and well made, and while building…

I'm excited to share a project that I've been working on mostly solo for the past year! It's called Elara, and it's a free open source game that teaches you how to code. You can play directly in your browser without downloading anything or creating an account. It's targeted toward complete beginners, but if you already have some coding experience, there are optional bonus challenges to really test your knowledge and problem-solving skills. If you like code golf, some of the challenges will be right up your alley ;) Under the hood, the backend/core game logic is built with Rust and…

Hi, I've made a Dis virtual machine and Limbo programming language compiler (called RiceVM) in Rust. It can run Dis bytecode (for example, Inferno OS applications), compile Limbo programs, and includes a fairly complete runtime with garbage collection, concurrency features, and many of the standard modules from Inferno OS's original implementation. The project is still in an early stage, but if you're interested in learning more about RiceVM or trying it out, you can check out the links below: Project's GitHub repo: https://github.com/habedi/ricevm RiceVM documentation:…

I built a Rust binary (~700KB, two dependencies) that snaps onto any Windows application, continuously reads its UI Automation accessibility tree into a SQLite database, and lets external processes control the app via SQL INSERT. The core insight: every GUI application already describes itself as structured text through the accessibility layer (built for screen readers since 1997). Every major AI lab is taking screenshots of this and running vision models on it. DirectShell just reads the text directly. What it does: - Reads every button, field, menu item into a queryable SQLite DB…

Hi HN! This Christmas I made `tysm`, a rust crates which simplifies using ChatGPT with Structured Outputs. Essentially you just tell it the rust type you want the output to conform to, and it handles creating the JSON Schema, passing it to ChatGPT's chat-completions API, and deserializing the response. Structured Outputs are very useful because they guarantee that the response will conform to whatever type you expect. I'm already finding my crate very useful since I love using Structured Outputs but I hate writing JSON Schemas myself. Technical details for rust heads: To generate the JSON…
