Chars+exprs

Make-chars+exprs

Basic constructor macro for chars+exprs structures.

Syntax

(make-chars+exprs [:chars <chars>] 
                  [:exprs <exprs>])

This is the usual way to construct chars+exprs structures. It simply conses together a structure with the specified fields.

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

Definition

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

Macro: make-chars+exprs

(defmacro make-chars+exprs (&rest args)
  (std::make-aggregate 'chars+exprs
                       args '((:chars) (:exprs))
                       'make-chars+exprs
                       nil))

Function: chars+exprs

(defun chars+exprs (chars exprs)
  (declare (xargs :guard (and (char-listp chars)
                              (expression-listp exprs))))
  (declare (xargs :guard t))
  (let ((__function__ 'chars+exprs))
    (declare (ignorable __function__))
    (b* ((chars (mbe :logic (char-list-fix chars)
                     :exec chars))
         (exprs (mbe :logic (expression-list-fix exprs)
                     :exec exprs)))
      (cons :chars+exprs (list (cons 'chars chars)
                               (cons 'exprs exprs))))))
