    Change-char-format

    Modifying constructor for char-format structures.

    Syntax
    (change-char-format x 
                        [:signedp <signedp>]) 
    

    This is an often useful alternative to make-char-format.

    We construct a new char-format 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-char-format

    (defmacro change-char-format (x &rest args)
      (std::change-aggregate 'char-format
                             x args
                             '((:signedp . char-format->signedp))
                             'change-char-format
                             'nil))
