Stmt-if

Make-stmt-if

Basic constructor macro for stmt-if structures.

Syntax

(make-stmt-if [:test <test>] 
              [:then <then>])

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

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

Definition

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

Macro: make-stmt-if

(defmacro make-stmt-if (&rest args)
  (std::make-aggregate 'stmt-if
                       args '((:test) (:then))
                       'make-stmt-if
                       nil))

Function: stmt-if

(defun stmt-if (test then)
  (declare (xargs :guard (and (exprp test) (stmtp then))))
  (declare (xargs :guard t))
  (let ((__function__ 'stmt-if))
    (declare (ignorable __function__))
    (b* ((test (mbe :logic (expr-fix test) :exec test))
         (then (mbe :logic (stmt-fix then)
                    :exec then)))
      (cons :if (list test then)))))
