Module Re.Posix

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 *)
exception Parse_error
exception Not_supported

Errors that can be raised during the parsing of the regular expression

type opt = [
| `ICase
| `NoSub
| `Newline
]
val re : ?⁠opts:opt list -> string -> Re__.Core.t

Parsing of a Posix extended regular expression

val compile : Re__.Core.t -> Re__.Core.re

Regular expression compilation

val compile_pat : ?⁠opts:opt list -> string -> Re__.Core.re

compile r is defined as Core.compile (Core.longest r)
