Vardecl

Make-vardecl

Basic constructor macro for vardecl structures.

Syntax

(make-vardecl [:name <name>] 
              [:type <type>] 
              [:init <init>])

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

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

Definition

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

Macro: make-vardecl

(defmacro make-vardecl (&rest args)
  (std::make-aggregate 'vardecl
                       args '((:name) (:type) (:init))
                       'make-vardecl
                       nil))

Function: vardecl

(defun vardecl (name type init)
  (declare (xargs :guard (and (identifierp name)
                              (typep type)
                              (expressionp init))))
  (declare (xargs :guard t))
  (let ((__function__ 'vardecl))
    (declare (ignorable __function__))
    (b* ((name (mbe :logic (identifier-fix name)
                    :exec name))
         (type (mbe :logic (type-fix type) :exec type))
         (init (mbe :logic (expression-fix init)
                    :exec init)))
      (cons :vardecl (list (cons 'name name)
                           (cons 'type type)
                           (cons 'init init))))))
