Building tomlt, a pure OCaml TOML 1.1 parser with bidirectional codecs following the jsont design patterns
Quite often, you install a new package from opam and are keen to jump right in and want a tailored example for your use case. This happened to me during Day 12 of Advent of Code.
Building an OCaml JMAP client that runs in browsers and CLI, then using it to build personalised email workflows for taming notification overload.
As I was very happy to announce on Discuss on 12 December, OCaml is Relocatable! Today, the final piece of the puzzle was merged, which is the necessary support to allow opam to take advantage of all this to be able to clone switches instead of recompiling them. Before this, you could rename a local switch, for example, but opam would still be compiling them from scratch. The fruits of this continue to be available through my opam-repository fork, as announced in September, and will be available out-of-the-box for the first alpha release of OCaml 5.5 early next year.
Building interactive OCaml tutorials that compile to JavaScript, using agents to generate executable documentation that teaches protocols like JSON Pointer while you code review.
Vibespiling JustHTML from Python to pure OCaml, achieving 100% pass rate on the browser html5lib test suite using agentic workflows.
Agentically synthesising a batteries-included OCaml HTTP client by gathering recommendations from fifty open-source implementations across JavaScript, Python, Java, Rust, Swift, Haskell, Go, C++, PHP and shell.
Vibe coding an OCaml library for the Karakeep bookmarking service by giving an agent a live API key and letting it debug jsont codecs against the real service.
