Allo. I'm Xavier Van de Woestyne from 🇧🇪, living in Nantes. I'm a wannabe software engineer who tweets in rough 🇫🇷 and catastrophic 🇬🇧! I'm interested in functional programming (with statically typed languages).

I'm really happy to present, with @tarides.com , #OCaml Eglot, an #Emacs (minor) mode for editing OCaml code, using LSP through Eglot, the built-in #LSP client of Emacs: github.com/tarides/ocam...

Feedback, contribution and RT much appreciated

0xCaml From a System Engineer's Point of View - Dmitriy Kovalenko - FUN OCaml 2025
0xCaml From a System Engineer's Point of View Dmitriy Kovalenko (LightSource) ABSTRACT I do a lot of Rust, C, Zig and whatever else cursed systems programming languages are there. So recently 0xCaml popped out and I was def interested if I can finally use it. So I did some research on how it actually works comparing to native OCaml and other languages and try to build odiff (the fastest image comparison lib in the world) with 0xCaml. Here is what I learned.

I was in the audience, and I loved this talk! Although it did lead to late night conversations about why we're allocating external memory in the first place in OCaml, instead of going full zero-copy. My thoughts here: anil.recoil.org/notes/icfp25...

I have now also resurrected the other old #ocaml article and converted the code examples from #reasonml :

https://citizen428.net/blog/ocaml-module-functors/
Module Functors in OCaml - citizen428.net
Note: A version of this article was originally written for Human Readable magazine in March 2020. That site no longer exists, so I decided to republish it on this blog. In the process I also converted the example code from ReasonML to OCaml syntax and updated the text to reflect those changes. Since functional programming’s move into the mainstream, many developers have embraced concepts like higher-order functions. OCaml take this a step further and extends the concept to the module level. This article explores module functors, a powerful feature that offers a functional approach to code sharing, dependency injection, and more.
