Binding

Make-binding

Basic constructor macro for binding structures.

Syntax

(make-binding [:variables <variables>] 
              [:value <value>])

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

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

Definition

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

Macro: make-binding

(defmacro make-binding (&rest args)
  (std::make-aggregate 'binding
                       args '((:variables) (:value))
                       'make-binding
                       nil))

Function: binding

(defun binding (variables value)
  (declare (xargs :guard (and (typed-variable-listp variables)
                              (expressionp value))))
  (declare (xargs :guard t))
  (let ((__function__ 'binding))
    (declare (ignorable __function__))
    (b* ((variables (mbe :logic (typed-variable-list-fix variables)
                         :exec variables))
         (value (mbe :logic (expression-fix value)
                     :exec value)))
      (list (cons 'variables variables)
            (cons 'value value)))))
