Products that do what Lumina Functional Programming Language does
My programming language Lumina now has a usable native x86 compiler, with a basic standard library for Linux. The goals are rather ambitious, but the results are starting to show. While platform and ecosystem support is currently very limited, I'm hoping to gather some first impressions and opinions on the design. As well as gauge the level of interest for this kind of language. Like mentioned in the README, there are some examples and a documentation page to get familiar with the language. Examples: https://github.com/luminalang/lumina/tree/main/examples…

I've been working on implementing the compile-time approach to memory management described in this thesis (https://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-908.pdf) for some time now - some of the performance results look promising! (Although some less so...) I think it would be great to see this taken further and built into a more complete functional language.

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!

Hey HN! I built Lumina – an open-source observability platform for AI/LLM applications. Self-host it in 5 minutes with Docker Compose, all features included. The Problem: I've been building LLM apps for the past year, and I kept running into the same issues: - LLM responses would randomly change after prompt tweaks, breaking things - Costs would spike unexpectedly (turns out a bug was hitting GPT-4 instead of 3.5) - No easy way to compare "before vs after" when testing prompt changes - Existing tools were either too expensive or missing features in free tiers What I Built: Lumina is…

Hi! I am doing a learning project, attempting to build an imperative language (and interpreter). The end product will be useless for others, I just want to learn and better understand how to build imperative languages. :) If someone else shares this interest and want to give some good hints on good resources I would be grateful. Currently I am looking at an awesome text by Bob Nystrom. All suggestions and tips on resources are most welcome. I am very much a beginner in this, but I find this topic very fascinating. Mail me or post links here! Cheers! You can try a beta version Online at…

Hi all, I've been working on a new programming language called Blade for a couple of months now and think it's time I introduced it to people and get reactions and feedbacks. Plus, I need people to test it and find the bugs in it. The repository is at https://github.com/blade-lang/blade and the documentation is in progress and going great at bladelang.com and even though I wanted to wait to write everything before I do this before, I think it's best to get started with letting people know about it now. There are lots of tests in the repository and experienced developers…

Hi there. I'm working on a programming language -- called Ink - in my spare time, with a friend. It uses LLVM for the backend, the parser and lexer are both hand written in C. The project is just for a bit of fun, we aren't trying to "revolutionize the programming language", but we're okay with being a bit quirky and out of the box with some of the syntax/features in the language. At the moment, the language is in it's early stages, and there's still a lot to do, which means that if you want to learn more about compilers, now would be a good time to start working on the language, since…

Hello, I'm the author of the nature programming language, which has reached an early usable version since its first commit in 2021 until today. --- Why implement such a programming language? go is a programming language that I use for my daily work, and the first time I used golang, I was amazed by its simple syntax, freedom of programming ideas, ease of cross-compilation and deployment, excellent and high-performance runtime implementations, and advanced concurrency style design based on goroutine, etc. But, golang also has some inconveniences - The syntax is too concise, resulting in a…

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…

Hi there, I built a React code editor component that also compiles, executes and returns the outputs of the program written in it (via pyodide/webassembly). I believe that this is a useful package for those building projects with web-based code editors. Expanding the library to be more flexible + have greater language support is a goal for the future. Hope it helps someone out there - please feel free to reach out if I can assist. Feedback and suggestions are always welcome.

I’m building Solnix, an experimental programming language as a learning + research project. It’s still early, and many design decisions (syntax, types, tooling) are intentionally not fixed yet. My goal right now is feedback, not promotion: What design mistakes should I watch out for? What usually makes new languages hard to adopt? What would you avoid if you were starting today? Repo & docs: https://solnix-lang.org/ I’d really appreciate honest criticism. Thanks for your time.

I’ve had this idea for a new code editor chord grammar bouncing around in my head for over 2 years, and now I can finally release v0.1 of ane. You can run it one-shot from scripts or agents (`ane exec —chord…`) or use its full-on TUI editor. ane is pure Rust, and integrates tree-sitter and LSP to provide a pleasant and predictable terminal code editing experience. I’d love folks to try it out and give feedback! Thanks :)

After six months of work, I am here again presenting Fluent – a tiny lang which is optimized for differentiable & reactive programming. Since I am not Conal Elliot, don't expect a beautiful theoretical unification of FRP and AD from first principles. Rather, a horrific monster that holds together mostly because a lot of duct-tape. The link points to the semi-interactive tour of the language, which will get the job done much better than I could in here. Hope you hate/like it!

Earlier this year, I took a month to reexamine my coding habits and rethink some past design choices. I hope to rewrite and improve my FOSS libraries this year, and I needed answers to a few questions first. Perhaps some of these questions will resonate with others in the community, too. - Are coroutines viable for high-performance work? - Should I use SIMD intrinsics for clarity or drop to assembly for easier library distribution? - Has hardware caught up with vectorized scatter/gather in AVX-512 & SVE? - How do secure enclaves & pointer tagging differ on Intel, Arm, & AMD? - What's…

Built a native Scratch 3.0 runtime in Lua that runs .sb3 projects without a browser. Why? Browser sandboxing prevents access to hardware features (haptics, sensors, fine-grained perf controls). Native runtime gives you direct hardware access and lets you deploy to consoles, handhelds, embedded devices. Also means much smaller binaries (LÖVE is ~7MB vs 50-100MB for Electron). How it works: - Scratch blocks compile to IR, then optimize, then generate Lua - LuaJIT executes the compiled code - Coroutine-based threading for concurrent scripts - Lazy loading + LRU cache for memory management - SVG…

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've been working on a new programming language for AI agents. I would love your input on what makes programming languages good for AI agents, especially syntax, compiler, and tooling that could help AI agents write code. What makes Sigil good for coding agents? I've turned conventions into compiler rules whenever possible. The compiler owns the canonical printer and every AST has one accepted textual representation. For almost every syntax feature I tried to save tokens. Order and naming conventions are enforced. No more "I think this argument is important so it should come first." Most…

Hey HN, I made a code editor which is inspired by Xi-editor. It's native GUI and GPU rendered written in Rust. A main feature is remote development support (VSCode like). Also other features like Vim-like modal editing, Tree-sitter for syntax highlighting, built-in LSP support and WASI based plugin system.

Hi HN! I kept hearing about Lisp and why it was special but didn't have a great place to start. I wanted something self-contained that helped me develop intuition rather than fluency. My hope is this is helpful for casual programmers, professionals from other fields who interact with code, or engineers who haven't had much exposure to interpreters or compilers. Hope this helps anyone else who's curious about getting a sense of Lisp and what makes it special with a limited time investment! Feedback or other cool Lisp things welcome :)
