Decl

Change-decl

Modifying constructor for decl structures.

Syntax

(change-decl x 
             [:name <name>] 
             [:type <type>])

This is an often useful alternative to make-decl.

We construct a new decl structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by defprod.

Macro: change-decl

(defmacro change-decl (x &rest args)
  (std::change-aggregate 'decl
                         x args
                         '((:name . decl->name)
                           (:type . decl->type))
                         'change-decl
                         'nil))
