Enumer

Change-enumer

Modifying constructor for enumer structures.

Syntax

(change-enumer x 
               [:name <name>] 
               [:value <value>])

This is an often useful alternative to make-enumer.

We construct a new enumer 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-enumer

                         x args
                         '((:name . enumer->name)
                           (:value . enumer->value))
                         'change-enumer
                         'nil))
