Jexpr-paren

Change-jexpr-paren

Modifying constructor for jexpr-paren structures.

Syntax

(change-jexpr-paren x 
                    [:get <get>])

This is an often useful alternative to make-jexpr-paren.

We construct a new jexpr-paren 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-jexpr-paren

(defmacro change-jexpr-paren (x &rest args)

                         'change-jexpr-paren
                         'nil))
