Namevalue+denv

Change-namevalue+denv

Modifying constructor for namevalue+denv structures.

Syntax

(change-namevalue+denv x 
                       [:namevalue <namevalue>] 
                       [:denv <denv>])

This is an often useful alternative to make-namevalue+denv.

We construct a new namevalue+denv 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.

                           (:denv . namevalue+denv->denv))
