Indentation-based syntax for Clojure

In plain words

This project introduces indentation-based syntax for Clojure, an alternative to the language's traditional parenthesis-heavy notation. It is designed for Clojure developers who prefer more readable, Python-like code formatting. The tool allows writing Clojure programs using indentation to denote structure instead of nested brackets, potentially reducing visual clutter while maintaining the same underlying functionality.

From the sources

Clojure is a practical dynamic functional programming language. This project provides familiar syntax, so it's easy to switch to it, from e.g. Python. def encode ( ^ String s, ^ long i) : let sb StringBuilder .() : doseq c s : cond : int(c) >= int( \ a) and int(c) <= int( \ z) .append(sb, char(int( \ a) + mod(int(c) - int( \ a) + i, 26 ))) int(c) >= int( \ A ) and int(c) <= int( \ Z ) .append(sb, char(int( \ A ) + mod(int(c) - int( \ A ) + i, 26 ))) : else .append(sb, c) .toString(sb) def decode ( ^ String s, ^ long i) : encode(s, 26 - i) Data manipulation def users : [{ : name to " John " , : age to 20 } { : name to " Anna " , : age to 32 } { : name to " Smith " , : age to 27 }] def avg -…from github.com

  I made a Clojure-like language in Go, boots in 7msMay 2026 · github.com · ▲292

  Let-go is a Clojure-like language (~90% compatible with JVM Clojure) written in pure Go. It ships as a ~10MB static binary and cold boots in ~7ms - that's about 50x faster than JVM and 3x faster than Babashka. It has decent throughput on algorithmic workloads - within ballpark of the GraalVM-backed sci. I started this project in 2021 as an elaborate practical joke: I wanted to have an excuse for writing Clojure while pretending to write Go. Jokes aside, it turned out to be pretty decent: it feels like real Clojure, it has an nREPL server (supported in Calva, CIDER, etc.), it's easily…

  Talanoa▲340

  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…

  Lovable▲1,477

  Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0,…

  I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https:&#x2F;&#x2F;github.com&#x2F;kentonv&#x2F;lanparty Anyway, if this shouldn't have been Show HN, I apologize!
