Version 0.4 of ringo is now available in opam. This version includes bug-fixes, minor (sometimes breaking) interface and semantics improvements, and, most importantly, a ringo-lwt package.

ringo-lwt provides wrapper for using caches in an Lwt-heavy application. Specifically, it provides a functor that transform a Ringo cache into a Ringo-lwt cache featuring:

  • val find_or_replace : 'a t -> key -> (key -> 'a Lwt.t) -> 'a Lwt.t which helps avoid race conditions,
  • automatic cleanup by which promises that are rejected are removed from the table automatically.

Additional functors for option (with automatic cleanup of None) and result (with automatic cleanup of Error) are also provided.
