Frame

Make-frame

Basic constructor macro for frame structures.

Syntax

(make-frame [:term <term>] 
            [:binding <binding>])

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 '((:term) (:binding))
                               'make-frame
                               nil))

Function: frame

(defun
     frame (term binding)
     (declare (xargs :guard (and (ttermp term) (bindingp binding))))
     (declare (xargs :guard t))
     (let ((__function__ 'frame))
          (declare (ignorable __function__))
          (b* ((term (mbe :logic (tterm-fix term)
                          :exec term))
               (binding (mbe :logic (binding-fix binding)
                             :exec binding)))
              (cons :frame (list term binding)))))
