Jstatem-for

Make-jstatem-for

Basic constructor macro for jstatem-for structures.

Syntax

(make-jstatem-for [:init <init>] 
                  [:test <test>] 
                  [:update <update>] 
                  [:body <body>])

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

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

Definition

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

Macro: make-jstatem-for

(defmacro make-jstatem-for (&rest args)
  (std::make-aggregate 'jstatem-for
                       args
                       '((:init) (:test) (:update) (:body))

                       nil))

Function: jstatem-for

(defun jstatem-for (init test update body)
  (declare (xargs :guard (and (jexprp init)
                              (jexprp test)
                              (jexprp update)
                              (jblockp body))))
  (declare (xargs :guard t))
  (let ((__function__ 'jstatem-for))
    (declare (ignorable __function__))
    (b* ((init (mbe :logic (jexpr-fix init)
                    :exec init))
         (test (mbe :logic (jexpr-fix test)
                    :exec test))
         (update (mbe :logic (jexpr-fix update)
                      :exec update))
         (body (mbe :logic (jblock-fix body)
                    :exec body)))
      (cons :for (list init test update body)))))
