I've created a complete, pure-OCaml YAML library called YAMLx (Yumyulack was too long). It will be suitable for reading config files in your applications as well as for analyzing YAML files used by other projects.
Aiming for a release by the end of this week.

The age of programming languages is over. I built one anyway.
Type inference. No annotations. Errors caught before they happen. The theory is from the 70s - compilers were doing "inference" long before #ai :)

Old mailing lists and their archives were replaced by Discord,Discourse and SO. Some mailing lists received thousands of mails and they were answered. Interesting times. Now #Java #OCaml mailing lists don't exist. Surprisingly Open JDK lists exist. LLMs hasten the demise of community engagement.

My exhaustiveness check for ocamllex was merged today and will be part of OCaml 5.6 🎉
About 50% of all mll files out there are affected and raise the exception 'Failure: empty token' on some input. An example of such input is now provided at compile time. github.com/ocaml/ocaml/... #ocaml
