README

noCanren is translator from subset of OCaml to OCanren.

Installatiom

noCanren can be installing using opam:

opam pin add noCanren https://github.com/Lozov-Petr/noCanren.git -y

To run the tests, you should install OCanren manually.

Subset of OCaml

Available syntax of OCaml subset:

S = x, y, z                                   (Variables)
  | fun x -> S                                (Abstaction)
  | S S                                       (Application)
  | false, 1, 2.0, '3', "4", etc.             (Constant)
  | (S, S)                                    (Pair)
  | C (S1, ..., Sn)                           (Constructor)
  | not, (&&), (||), (==), (<>)               (Boolean functions)
  | let f x1 ... xn = S in S                  (Let-binding)
  | let rec f x1 ... xn = S in S              (Recursive let-binding)
  | if S then S else S                        (If-then-else)
  | pattern matching                          (Pattern matching)

Pattern matching

Available patterns for pattern matching:

P = _                                         (Wildcard)
  | x, y, z                                   (Variables)
  | (P, P)                                    (Pairs)
  | C (P1, ..., Pn)                           (Constructors)

Patterns must be disjunct.

Pattern matching can be used in the following form:

match S with
| P1 -> S1
| P2 -> S2
...
| Pn -> Sn

Translating

Usage:

noCanren <options> <input-file>
