I just released v0.2 of http-date, an RFC 9110 compliant HTTP datetime decoder/encoder for OCaml.
This is a major rewrite from v0.1. Here’s what changed:
Zero dependencies — Replaced the ocamllex/menhir parser with a hand-written implementation and removed the ptime dependency entirely. The library now only requires ocaml and dune.
New type-safe API — The parsed result is now a polymorphic variant tagged by format (IMF, RFC850, ASCTIME), so you always know which HTTP date format was parsed. The dayname, date, time, and datetime types are all exposed in the public API.
Serious testing — Added property-based tests with alcobar and AFL fuzz testing infrastructure to build confidence in the hand-written parser.
If you’re working with HTTP headers in OCaml, give it a try:
opam install http-date
