21synopsis: "Matching Regular Expressions with OCaml Patterns"
22description: """
23This syntax extension turns
24
25 match%pcre x with
26 | {|re1|} -> e1
27 ...
28 | {|reN|} -> eN
29 | _ -> e0
30
31into suitable invocations of the ocaml-re library. The patterns are plain
32strings of the form accepted by `Re_pcre`, with the following additions:
33
34 - `(?<var>...)` defines a group and binds whatever it matches as `var`.
35 The type of `var` will be `string` if the match is guaranteed given that
36 the whole pattern matches, and `string option` if the variable is bound
37 to or nested below an optionally matched group.
38
39 - `?<var>` at the start of a pattern binds group 0 as `var : string`.
40 This may not be the full string if the pattern is unanchored.
41
42A variable is allowed for the universal case and is bound to the matched
43string. A regular alias is currently not allowed for patterns, since it is
44not obvious whether is should bind the full string or group 0."""
