Jexpr-newclass

Make-jexpr-newclass

Basic constructor macro for jexpr-newclass structures.

Syntax

(make-jexpr-newclass [:type <type>] 
                     [:args <args>])

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

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

Definition

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

Macro: make-jexpr-newclass

(defmacro make-jexpr-newclass (&rest args)
  (std::make-aggregate 'jexpr-newclass
                       args '((:type) (:args))
                       'make-jexpr-newclass
                       nil))

Function: jexpr-newclass

(defun jexpr-newclass (type args)
  (declare (xargs :guard (and (jtypep type) (jexpr-listp args))))
  (declare (xargs :guard t))
  (let ((__function__ 'jexpr-newclass))
    (declare (ignorable __function__))
    (b* ((type (mbe :logic (jtype-fix type)
                    :exec type))
         (args (mbe :logic (jexpr-list-fix args)
                    :exec args)))
      (cons :newclass (list type args)))))
