Member-value

Change-member-value

Modifying constructor for member-value structures.

Syntax

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

This is an often useful alternative to make-member-value.

We construct a new member-value 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-member-value

                           (:value . member-value->value))
                         'change-member-value
                         'nil))
