Stmt-ifelse

Make-stmt-ifelse

Basic constructor macro for stmt-ifelse structures.

Syntax

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

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

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

Definition

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

Macro: make-stmt-ifelse

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

Function: stmt-ifelse

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