Outreachy December 2024 Demo: The OCaml community participated in the December 2024 round of [Outreachy internships](https://www.outreachy.org). One intern worked on a tool for diffing OCaml APIs.

This meeting was an opportunity for our intern to present their work and for ... https://watch.ocaml.org/videos/watch/70ef58ff-ff7c-40d6-ab19-e886e4e98205?utm_source=dlvr.it&utm_medium=mastodon #OCaml #OCamlPlanet

Dune.3.18.1: The Dune Team is happy to announce the release of Dune 3.18.1!

This release contains a bug fix for pkg-config that prevents it from finding some
libraries in specific contexts. https://ocaml.org/changelog/2025-04-17-dune.3.18.1?utm_source=dlvr.it&utm_medium=mastodon #OCaml #OCamlChangelog

I think what it might be is outdated things that trying to use `ocaml-monorepo` brings in when you have to fill-in for certain libraries.

Here's a special little error. I'm wondering if my dune build isn't using what's on disk, but the checked in git code, and I'm getting an error:

`[NOTE] Ignoring uncommitted changes in /workspaces/haxe-compiler-dev/vendor/haxe (`--working-dir' not specified or specified with no
argument).`

Only, thing is, I've tried adding `--working-dir` but `dune` doesn't recognise it, and isn't telling me who it is that needs the argument.

Neither Google nor Bing are telling me anything.

fuck

edit (wait, nope, my bad)

People sometimes ask which #unikernel we actively use (as proof of our work). Currently, https://paste.osau.re is a unikernel in #OCaml, and it has been running (without interruption) for over a year. Feel free to use this service (free of charge) to share code snippets, and if you like what we do, you can sponsor us via GitHub (https://github.com/sponsors/robur-coop).

I've created an scgi library for #ocaml

https://git.sr.ht/~marcc/scgi-eio

tori will be rewritten in another programming language. But which one? The contenders are OCaml, Haskell and Rust and the decision will be made by implementing a simplistic subset of its functionality in an experimental project called iganaq.

For more details, the reasons behind the rewrite and the candidate languages, see the announcement here:

https://tori.jutty.dev/updates/iganaq

Or go straight to the code, where the OCaml implementation is almost done already:

I'm writing #assembly in #ocaml

Expanding Dune Package Management to the Rest of the Ecosystem: Since we published The Dune Developer Preview a lot of things have improved on the package management front. While the developer preview has demonstrated how Dune can manage dependencies in a unified workflow, we have been working on making it practical for more projects to adopt Dune to handle their package dependencies. Our goal is to slowly move from a developer preview to a mature… https://tarides.com/blog/2025-04-11-expanding-dune-package-management-to-the-rest-of-the-ecosystem?utm_source=dlvr.it&utm_medium=mastodon #OCaml #OCamlPlanet
