I do not mind at all. It is a good way to learn how you intend the
code to be used. with-gl is a simple macro:
(defmacro with-gl (value &body body)
`(progn (glBegin ,value)
, at body
Not much to it, but what it buys you in a Lisp-aware editor is
indentation of the code wrapped by the glBegin and glEnd. I think it
makes things a bit more readable.
slui is a wrapper to a call to cl-who:html. It was suggested by
someone on this list a while back as an alternative to writing XML to
define the UI's. I see < and > and can not help but think of them
more as angry parenthesis, and I am worried that they might try to
pick a fight with some of the meeker members of my code. So I try to
avoid them when I can.
(defmacro slui (s-expression)
`(let* ((*read-eval* t)
(s nil :indent t)
I'll keep those tutorials coming as I can get to them.
