Vl-pattern

Change-vl-pattern

Modifying constructor for vl-pattern structures.

Syntax

(change-vl-pattern x 
                   [:pat <pat>] 
                   [:pattype <pattype>] 
                   [:atts <atts>])

This is an often useful alternative to make-vl-pattern.

We construct a new vl-pattern 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 defprod.

Macro: change-vl-pattern

(defmacro change-vl-pattern (x &rest args)

                         x args
                         '((:pat . vl-pattern->pat)
                           (:pattype . vl-pattern->pattype)
                           (:atts . vl-pattern->atts))
                         'change-vl-pattern
                         'remake-vl-pattern))
