Enum-spec

Change-enum-spec

Modifying constructor for enum-spec structures.

Syntax

(change-enum-spec x 
                  [:name? <name?>] 
                  [:enumers <enumers>] 
                  [:final-comma <final-comma>])

This is an often useful alternative to make-enum-spec.

We construct a new enum-spec 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.
