Config

Change-config

Modifying constructor for config structures.

Syntax

(change-config x 
               [:comms <comms>] 
               [:env <env>])

This is an often useful alternative to make-config.

We construct a new config 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
