When I started learning OCaml I kept running into code like this:
If there’s one thing that frustrated me early on in my OCaml journey, it was printing stuff. In Ruby I can p anything and get a useful representation. In Clojure, prn just works on every data structure. In OCaml? There’s no generic print that works on any type – the type information is erased at runtime, so the language simply doesn’t know how to stringify an arbitrary value.
Records are one of those things that look almost identical across ML-family languages, so I didn’t expect many surprises when I started using them in OCaml. For the most part I was right – but there were a few things worth noting, especially if you’re coming from a language where records/structs are mutable by default.
Got TESSERA working in Zarr and the browser, and a preprint of package management a la carte pushed out
Over the past year I’ve been spending a lot of time building Tree-sitter-powered major modes for Emacs – clojure-ts-mode (as co-maintainer), neocaml (from scratch), and asciidoc-mode (also from scratch). Between the three projects I’ve accumulated enough knowledge (and battle scars) to write about the experience. This post distills the key lessons for anyone thinking about writing a Tree-sitter-based major mode, or curious about what it’s actually like.

The problem statement: no isolation, no standard packaging, no OTA updates. Three missing pieces for multi-tenant satellite payloads.
A few years ago I wrote about setting up Emacs for OCaml development. Back then the recommended stack was tuareg-mode + merlin-mode, with Merlin providing the bulk of the IDE experience. A lot has changed since then – the OCaml tooling has evolved considerably, and I’ve been working on some new tools myself. Time for an update.
