Function

Change-function

Modifying constructor for function structures.

Syntax

(change-function x 
                 [:name <name>] 
                 [:inputs <inputs>] 
                 [:instrs <instrs>] 
                 [:outputs <outputs>] 
                 [:finalize <finalize>])

This is an often useful alternative to make-function.

We construct a new function 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-function

(defmacro change-function (x &rest args)
  (std::change-aggregate 'function
                         x args
                         '((:name . function->name)
                           (:inputs . function->inputs)
                           (:instrs . function->instrs)
                           (:outputs . function->outputs)
                           (:finalize . function->finalize))
                         'change-function
                         'nil))
