Fty-info

Change-fty-info

Modifying constructor for fty-info structures.

Syntax

(change-fty-info x 
                 [:name <name>] 
                 [:category <category>] 
                 [:type <type>] 
                 [:guards <guards>] 
                 [:returns <returns>])

This is an often useful alternative to make-fty-info.

We construct a new fty-info 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.
