Dec-frac-const

Make-dec-frac-const

Basic constructor macro for dec-frac-const structures.

Syntax

(make-dec-frac-const [:before <before>] 
                     [:after <after>])

This is the usual way to construct dec-frac-const structures. It simply conses together a structure with the specified fields.

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

Definition

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

Macro: make-dec-frac-const

(defmacro make-dec-frac-const (&rest args)
  (std::make-aggregate 'dec-frac-const
                       args '((:before) (:after))
                       'make-dec-frac-const
                       nil))

Function: dec-frac-const

(defun dec-frac-const (before after)
  (declare (xargs :guard (and (dec-digit-char-listp before)
                              (dec-digit-char-listp after))))
  (declare (xargs :guard t))
  (let ((__function__ 'dec-frac-const))
    (declare (ignorable __function__))
    (b* ((before (mbe :logic (str::dec-digit-char-list-fix before)
                      :exec before))
         (after (mbe :logic (str::dec-digit-char-list-fix after)
                     :exec after)))
      (list (cons 'before before)
            (cons 'after after)))))
