Borgo – a Rusty language that compiles to Go

In plain words

Borgo is a programming language with Rust-like syntax that compiles to Go. It adds features from ML-like languages including sum types, pattern matching, and Option/Result types while maintaining Go's garbage collection and straightforward concurrency model. The language aims to be compatible with existing Go packages through automatic binding generation, allowing developers to access Go's third-party ecosystem. The compiler is functional but incomplete, and an online playground is available for testing.

From the sources

For a high-level overview of the features and instructions on running the compiler locally, check the README . This playground runs the compiler as a wasm binary and then sends the transpiled go output to the official Go playground for execution. Collections like slices and maps can be used without specifying the type of the values. For example, a slice of int elements would be declared as []int{1,2,3} in Go, whereas Borgo relies on type inference to determine the type, so you can just write [1, 2, 3] . Maps are initialized with the Map.new() function, which under the hood compiles to a map[K]V{} expression, with the K and V types helpfully filled in for you. Multiline strings are defined…from borgo-lang.github.io

In the maker’s words, at launch

Hey HN Borgo is a programming language I've been working on for the past year. It looks like Rust (because I didn't want to write a parser) and compiles to Go. What I want from a programming language is: - Sum types - Pattern matching - Option/Result types - Garbage collected - Concurrency without async - Good…

  A Database Written in Golang2025 · github.com · ▲277

  Recently created a minimal persistent relational database in Go. Main focus was on implementing & understanding working the of database, storage management & transaction handling. Use of B+ Tree for storage engine(support for indexing), managing a Free List (for reusing nodes), Support for transactions, Concurrent Reads. Still have many things to add & fix like query processing being one of the main & fixing some bugs Repo link - https://github.com/Sahilb315/AtomixDB Would love to hear your thoughts

  Han – A Korean programming language written in RustMar 2026 · github.com · ▲208

  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 →…

  A new stdlib for Golang focusing on platform native support2023 · github.com · ▲154

  No gc, No goroutines, Produces small binaries while using the unmodified official go toolchain, and comes with complete Web SDK (generated from w3c/webref). We are building `pcz` to provide a reimagination of Go the language, in an effort to make it suitable for all kinds of programming tasks, and currently you can use it to build efficient web applications in Go using the generated Web SDK (as shown with the live web demo[1]). The journey is just starting, any suggestions? or any critics? [1]: https://primecitizens.github.io/livedemos/10-plat-web/

  htmgo - build simple and scalable systems with golang + htmx2024 · htmgo.dev · ▲166

  Hey all, I just wanted to share a project I've been working on for the past month. After years of heavy frameworks, I really like the idea of using htmx, but it’s a little too low level for me and needs a thin layer above it to facilitate things like components, better syntax with complex JS inside of an attribute, etc To try and solve this problem with a very minimal stack (golang + htmx) that I've been really enjoying, I'm building this project to cater to my needs and was thinking it would be useful for other developers.

  Lingo – A linguistic database in Rust with nanosecond-level performance2025 · ▲42

  Hi HN, I made Lingo - the SQLite of semantic search. I'm a self-taught developer and researcher who left school at 16, and I've spent some time exploring a first-principles approach to system design for various frontier problems. In this case it's AI that challenges the 'bigger is better' transformer paradigm. Lingo is the first piece of that research, a high-performance linguistic database designed to run on-device. The full technical overview and manifesto is here: https://medium.com/@robm.antunes/bcd1e9752af6 The paper has been archived on Zenodo with a DOI:…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I saw this [0] pretty cool thread by user revskill, and wanted a quicker way to search through it, but also to keep them all in one place so I can read them at my leisure whenever I get time. Right now is like 60 lines of Ruby using Nokogiri, but I will certainly look into it further down the line and improve the list. There's a cronjob checking the thread every 12 hours but I will eventually shut that down and it will become static after that. There are some really awesome blogs in there. I really recommend going through the list, it made my day. [0] "Could you share your personal blog…
