I've just released gosax, a new Go library for high-performance SAX (Simple API for XML) parsing. It's designed for efficient, memory-conscious XML processing, drawing inspiration from quick-xml and pkg/json. https://github.com/orisano/gosax Key features: - Read-only SAX parsing - Highly efficient parsing using techniques inspired by quick-xml and pkg/json - SWAR (SIMD Within A Register) optimizations for fast text processing gosax is particularly useful for processing large XML files or streams without loading the entire document into memory. It's well-suited…

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…

Hi HN. I've gotten pretty tired of needing to learn a custom programming language for a tool I use once a week or less. So I figured, it might be easier to pick up if `jq` used a programming language I already know. Voila, gq.

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/

Serialization framework with some interesting numbers: 10-20x faster on nested objects than json/protobuf. Technical approach: compile-time codegen (no reflection), compact binary protocol with meta-packing, little-endian layout optimized for modern CPUs. Unique features that other fast serializers don't have: - Cross-language without IDL files (Rust ↔ Python/Java/Go) - Trait object serialization (Box) - Automatic circular reference handling - Schema evolution without coordination Happy to discuss design trade-offs. Benchmarks:…

Hello HN! I want to introduce fastgron, my new project. fastgron is a JSON to GRON converter, built to be incredibly fast – it's 40 times faster than Gron. GRON is a tool for making JSON greppable, but it can slow down with larger files. With fastgron, even a 200MB JSON file can be converted in just 1 second. Key features include streaming conversion for memory efficiency and an optimized path reconstruction for faster operations. It leverages C++ and the simdjson and fast_io libraries for speed. I welcome all feedback, suggestions, or questions. Thank you!

- What's different? It's fast. On my machine, the stream decoder is faster than bytedance/sonic which claim to be the fastest even though mine is written in pure Go and Sonic is written in Go + C + Assembly. It also is a drop-in replacement of the standard library. - Why is it fast? technologies used are in my articles (available in English and Japanese) EN: https://sugawarayuuta.medium.com/still-i-wanted-to-build-the...
