    Change-constdecl

    Modifying constructor for constdecl structures.

    Syntax
    (change-constdecl x 
                      [:name <name>] 
                      [:type <type>] 
                      [:init <init>]) 
    

    This is an often useful alternative to make-constdecl.

    We construct a new constdecl 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 fty::defprod.

    Macro: change-constdecl

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