Value-symbol

Change-value-symbol

Modifying constructor for value-symbol structures.

Syntax

(change-value-symbol x 
                     [:get <get>])

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

We construct a new value-symbol 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-value-symbol

(defmacro change-value-symbol (x &rest args)
  (std::change-aggregate 'value-symbol
                         x args '((:get . value-symbol->get))
                         'change-value-symbol
                         'nil))
