Dynamic semantics

Values are represented in a way similar to OCaml, i.e. they contrast immediate integers (integers, constructors without arguments) and structured blocks (tuples, arrays, constructors with arguments), as well as a few other base cases, namely closures, strings, named constructors, and dynamic type coming from the Coq implementation.

type tag = int
type closure
type valexpr =
  1. | ValInt of int
    (*

    Immediate integers

    *)
  2. | ValBlk of tag * valexpr array
    (*

    Structured blocks

    *)
  3. | ValStr of Stdlib.Bytes.t
    (*

    Strings

    *)
  4. | ValCls of closure
    (*

    Closures

    *)
  5. | ValOpn of Names.KerName.t * valexpr array
    (*

    Open constructors

    *)
  6. | ValExt : 'a Tac2dyn.Val.tag * 'a -> valexpr
    (*

    Arbitrary data

    *)
module Valexpr : sig ... end

Closures

type 'a arity
val arity_one : (valexpr -> valexpr Proofview.tactic) arity
val arity_suc : 'a arity -> (valexpr -> 'a) arity
val mk_closure : 'v arity -> 'v -> closure
val mk_closure_val : 'v arity -> 'v -> valexpr

Composition of mk_closure and ValCls

val annotate_closure : Tac2expr.frame -> closure -> closure

The closure must not be already annotated

val to_closure : valexpr -> closure
val apply : closure -> valexpr list -> valexpr Proofview.tactic

Given a closure, apply it to some arguments. Handling of argument mismatches is done automatically, i.e. in case of over or under-application.

val apply_val : valexpr -> valexpr list -> valexpr Proofview.tactic

Composition of to_closure and apply

val abstract : int -> (valexpr list -> valexpr Proofview.tactic) -> closure

Turn a fixed-arity function into a closure. The inner function is guaranteed to be applied to a list whose size is the integer argument.
