Jexpr-array

Make-jexpr-array

Basic constructor macro for jexpr-array structures.

Syntax

(make-jexpr-array [:array <array>] 
                  [:index <index>])

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

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

Definition

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

Macro: make-jexpr-array

(defmacro make-jexpr-array (&rest args)
  (std::make-aggregate 'jexpr-array
                       args '((:array) (:index))
                       'make-jexpr-array
                       nil))

Function: jexpr-array

(defun jexpr-array (array index)
  (declare (xargs :guard (and (jexprp array) (jexprp index))))
  (declare (xargs :guard t))
  (let ((__function__ 'jexpr-array))
    (declare (ignorable __function__))
    (b* ((array (mbe :logic (jexpr-fix array)
                     :exec array))
         (index (mbe :logic (jexpr-fix index)
                     :exec index)))
      (cons :array (list array index)))))
