Module `Re.Posix`Source

References:

Example of how to use this module (to parse some IRC logs):

  type msg =
    { time : string
    ; author : string
    ; content : string
    }

  let re = Core.compile (Re_posix.re "([^:].*:[^:]*:[^:]{2})<.([^>]+)> (.+)$")

  (* parse a line *)
  let match_line line =
    try
      let substrings = Core.exec re line in
      let groups = Core.get_all substrings in
      (* groups can be obtained directly by index within [substrings] *)
      Some { time = groups.(1); author = groups.(2); content = groups.(3) }
    with
    | Not_found -> None (* regex didn't match *)
  ;;
