Ident

Change-ident

Modifying constructor for ident structures.

Syntax

(change-ident x 
              [:unwrap <unwrap>])

This is an often useful alternative to make-ident.

We construct a new ident 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-ident

(defmacro change-ident (x &rest args)
  (std::change-aggregate 'ident
                         x args '((:unwrap . ident->unwrap))
                         'change-ident
                         'nil))
