Output-item

Change-output-item

Modifying constructor for output-item structures.

Syntax

(change-output-item x 
                    [:get <get>])

This is an often useful alternative to make-output-item.

We construct a new output-item 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.

                         'change-output-item
                         'nil))
