Repeat-range

Make-repeat-range

Basic constructor macro for repeat-range structures.

Syntax

(make-repeat-range [:min <min>] 
                   [:max <max>])

This is the usual way to construct repeat-range structures. It simply conses together a structure with the specified fields.

This macro generates a new repeat-range structure from scratch. See also change-repeat-range, which can "change" an existing structure, instead.

Definition

This is an ordinary make- macro introduced by fty::defprod.

                       args '((:min) (:max))
                       'make-repeat-range
                       nil))

Function: repeat-range

(defun repeat-range (min max)
  (declare (xargs :guard (and (natp min) (natip max))))
  (declare (xargs :guard t))

    (declare (ignorable __function__))
    (b* ((min (mbe :logic (nfix min) :exec min))
         (max (mbe :logic (acl2::nati-fix max)
                   :exec max)))
      (cons :repeat (list min max)))))
