Matchresult

Change-matchresult

Modifying constructor for matchresult structures.

Syntax

(change-matchresult x 
                    [:loc <loc>] 
                    [:len <len>] 
                    [:str <str>] 
                    [:backrefs <backrefs>])

This is an often useful alternative to make-matchresult.

We construct a new matchresult 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
