Stmt-for

Make-stmt-for

Basic constructor macro for stmt-for structures.

Syntax

(make-stmt-for [:init <init>] 
               [:test <test>] 
               [:next <next>] 
               [:body <body>])

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

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

Definition

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

Macro: make-stmt-for

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

Function: stmt-for

(defun stmt-for (init test next body)
  (declare (xargs :guard (and (expr-optionp init)
                              (expr-optionp test)
                              (expr-optionp next)
                              (stmtp body))))
  (declare (xargs :guard t))
  (let ((__function__ 'stmt-for))
    (declare (ignorable __function__))
    (b* ((init (mbe :logic (expr-option-fix init)
                    :exec init))
         (test (mbe :logic (expr-option-fix test)
                    :exec test))
         (next (mbe :logic (expr-option-fix next)
                    :exec next))
         (body (mbe :logic (stmt-fix body)
                    :exec body)))
      (cons :for (list init test next body)))))
