Jexpr-binary

Make-jexpr-binary

Basic constructor macro for jexpr-binary structures.

Syntax

(make-jexpr-binary [:op <op>] 
                   [:left <left>] 
                   [:right <right>])

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

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

Definition

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

Macro: make-jexpr-binary

(defmacro make-jexpr-binary (&rest args)
  (std::make-aggregate 'jexpr-binary
                       args '((:op) (:left) (:right))
                       'make-jexpr-binary
                       nil))

Function: jexpr-binary

(defun jexpr-binary (op left right)
  (declare (xargs :guard (and (jbinopp op)
                              (jexprp left)
                              (jexprp right))))
  (declare (xargs :guard t))
  (let ((__function__ 'jexpr-binary))
    (declare (ignorable __function__))
    (b* ((op (mbe :logic (jbinop-fix op) :exec op))
         (left (mbe :logic (jexpr-fix left)
                    :exec left))
         (right (mbe :logic (jexpr-fix right)
                     :exec right)))
      (cons :binary (list op left right)))))
