    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

    This is an ordinary change- macro introduced by fty::defprod.

    Macro: change-config

    (defmacro change-config (x &rest args)
      (std::change-aggregate 'config
                             x args
                             '((:comms . config->comms)
                               (:env . config->env))
                             'change-config
                             'nil))
