Statement-for

Make-statement-for

Basic constructor macro for statement-for structures.

Syntax

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

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

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

Definition

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

Macro: make-statement-for

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

Function: statement-for

(defun statement-for (init test update body)
  (declare (xargs :guard (and (blockp init)
                              (expressionp test)
                              (blockp update)
                              (blockp body))))
  (declare (xargs :guard t))
  (let ((__function__ 'statement-for))
    (declare (ignorable __function__))
    (b* ((init (mbe :logic (block-fix init)
                    :exec init))
         (test (mbe :logic (expression-fix test)
                    :exec test))
         (update (mbe :logic (block-fix update)
                      :exec update))
         (body (mbe :logic (block-fix body)
                    :exec body)))
      (cons :for (list init test update body)))))
