Sorted

Sourceval p_close : pred -> pred

Quantify over (sorted) free variables

Sourceval pp_tau : Format.formatter -> tau -> unit
Sourceval pp_var : Format.formatter -> var -> unit
Sourceval pp_vars : Format.formatter -> Vars.t -> unit
Sourceval pp_term : Format.formatter -> term -> unit
Sourceval pp_pred : Format.formatter -> pred -> unit
Sourceval debugp : Format.formatter -> pred -> unit
Sourcetype env
Sourceval context_pp : env Context.value

Context used by pp_term, pp_pred, pp_var, ppvars for printing the term. Allows to keep the same disambiguation.

Sourcetype marks = QED.marks
Sourceval env : Vars.t -> env
Sourceval marker : env -> marks
Sourceval mark_e : marks -> term -> unit
Sourceval mark_p : marks -> pred -> unit

Returns a list of terms to be shared among all shared or marked subterms. The order of terms is consistent with definition order: head terms might be used in tail ones.

Sourceval define : (env -> string -> term -> unit) -> env -> marks -> env

Sourceval occurs : var -> term -> bool
Sourceval occursp : var -> pred -> bool
Sourceval intersect : term -> term -> bool

Sourceval is_subterm : term -> term -> bool
Sourceval typeof : ?field:(Field.t -> tau) -> ?record:(Field.t -> tau) -> ?call:(Fun.t -> tau option list -> tau) -> term -> tau

Try to extract a type of term. Parameterized by optional extractors for field and functions. Extractors may raise Not_found ; however, they are only used when the provided kinds for fields and functions are not precise enough.

  • parameter field

    type of a field value

  • parameter record

    type of the record containing a field

  • parameter call

    type of the values returned by the function

Builtins

The functions below register simplifiers for function f. The computation code may raise Not_found, in which case the symbol is not interpreted.

If f is an operator with algebraic rules (see type operator), the children are normalized before builtin call.

Highest priority is 0. Recursive calls must be performed on strictly smaller terms.
