Schar-array

Make-schar-array

Basic constructor macro for schar-array structures.

Syntax

(make-schar-array [:elemtype <elemtype>] 
                  [:elements <elements>])

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

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

Definition

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

Macro: make-schar-array

(defmacro make-schar-array (&rest args)
  (std::make-aggregate 'schar-array
                       args '((:elemtype) (:elements))
                       'make-schar-array
                       nil))

Function: schar-array

(defun schar-array (elemtype elements)
  (declare (xargs :guard (and (typep elemtype)
                              (schar-listp elements))))
  (declare (xargs :guard (and (type-case elemtype :schar)
                              (consp elements))))
  (let ((__function__ 'schar-array))
    (declare (ignorable __function__))
    (b* ((elemtype (mbe :logic (type-fix elemtype)
                        :exec elemtype))
         (elements (mbe :logic (schar-list-fix elements)
                        :exec elements)))
      (let ((elemtype (mbe :logic
                           (if (type-case elemtype :schar)
                               elemtype
                             (type-schar))
                           :exec elemtype))
            (elements (mbe :logic
                           (if (consp elements)
                               elements
                             (list (schar-from-integer 0)))
                           :exec elements)))
        (cons :array (list elemtype elements))))))
