Frame

Make-frame

Basic constructor macro for frame structures.

Syntax

(make-frame [:function <function>] 
            [:scopes <scopes>])

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

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

Definition

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

Macro: make-frame

(defmacro make-frame (&rest args)
  (std::make-aggregate 'frame
                       args '((:function) (:scopes))
                       'make-frame
                       nil))

Function: frame

(defun frame (function scopes)
 (declare (xargs :guard (and (identp function)
                             (scope-listp scopes))))
 (declare (xargs :guard (consp scopes)))
 (let ((__function__ 'frame))
   (declare (ignorable __function__))
   (b* ((function (mbe :logic (ident-fix function)
                       :exec function))
        (scopes (mbe :logic (scope-list-fix scopes)
                     :exec scopes)))
     (let ((scopes (mbe :logic (if (consp scopes) scopes (list nil))
                        :exec scopes)))
       (list (cons 'function function)
             (cons 'scopes scopes))))))
