Jexpr-unary

Make-jexpr-unary

Basic constructor macro for jexpr-unary structures.

Syntax

(make-jexpr-unary [:op <op>] 
                  [:arg <arg>])

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

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

Definition

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

Macro: make-jexpr-unary

(defmacro make-jexpr-unary (&rest args)
  (std::make-aggregate 'jexpr-unary
                       args '((:op) (:arg))
                       'make-jexpr-unary
                       nil))

Function: jexpr-unary

(defun jexpr-unary (op arg)
  (declare (xargs :guard (and (junopp op) (jexprp arg))))
  (declare (xargs :guard t))
  (let ((__function__ 'jexpr-unary))
    (declare (ignorable __function__))
    (b* ((op (mbe :logic (junop-fix op) :exec op))
         (arg (mbe :logic (jexpr-fix arg) :exec arg)))
      (cons :unary (list op arg)))))
