noCanren is translator from subset of OCaml to OCanren.
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)
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
