sabine 🐫🦀 / "use ocaml";

guys do you know anyone in Poland in tech who runs meetups or other communities where they could promote FUN OCaml?

The best time to start learning OCaml was 10 years ago, the second best time is now

Many years ago (2006 or so?) I had a side project , and did the classic "gotta choose the perfect programming language first" thing.

I decided on Python, but came *this* close to choosing OCaml.

So, yeah…I guess we all have regrets, don't we.

yes we should

Let's run a workshop in fun-ocaml, should we?

so looking forward to this!

much of the ocaml experience is discovering just how often the answer to "did someone at jane street already deal with this problem" is "yes"

discuss.ocaml.org/t/dream-deve...

is it possible to emit ocaml bytecode at runtime that is loaded and ran?

The basic issue is that OCaml's module system, despite being a really good foundation for building modular software, has fundamental scaling problems. There's just too much syntactic overhead involved in parameterizing (in OCaml jargon, functorizing) a complex codebase.

We've finally landed a full version internally (coming to an OxCaml near you soon!) of a new feature called parameterized libraries.

It's basically an answer to a problem I first ran into 23 years ago. Here's a thread about it on the caml-list.

inbox.vuxu.org/caml-list/10...

TIL I could use `#variant_name` to split up a polymorphic variant in OCaml e.g.

type standard_status = [`OK, | `Bad_request | ...]
type status = [standard_status | `Status of int]

let normalised_status status = match status with
| `Status x -> Status.of_code x
| \#standard_status as s -> s

makes sense! I think having mlx list this would go a long way

The Stack Overflow 2025 survey results are online. Nothing has changed for Scala; it still has its 2.6%. Meanwhile, Rust and Kotlin are growing, while Java has declined slightly. Interestingly, I don't see Haskell on the list anymore. 😳 #scala #java #rust #kotlin #elixir #fsharp #ocaml #gleam

ahhh yes, overlooking this entirely explains your experience

Leo has been around all along, just taking a break from social media to focus

(incidentally, I made him sign on and comment, so you know he's gonna be at FUN OCaml 😅😆)

can confirm, this has been the most pleasant experience writing HTML I ever had in a statically typed language

"State of the OCaml Ecosystem 2025" digs into real GitHub data - repo activity, contributor trends, and which libraries are gaining traction.

See the numbers behind OCaml's momentum and where it's headed.

Conference slide for FUNOCaml 2025, September 15-16 in Warsaw, Poland. Shows a talk titled 'Cross-Platform OCaml Projects' by Manas Jayanth, with a pixelated profile photo. The description reads: 'OCaml's ecosystem includes many platform-specific packages that can break portability when transitive dependencies won't work across different operating systems. Manas Yayanth explains how they implemented portable lock files for esy (the Reason/OCaml package manager), ensuring projects can be built cross-platform

🚀 Manas Jayanth is presenting "Cross-Platform OCaml Projects" at FUNOCaml 2025 in Warsaw!

They'll share how they implemented portable lock files for esy (Reason/OCaml package manager) to achieve reproducible builds across different operating systems.
