RE: Rule docstrings

That's a good idea, and an oversight on my part. I'll export the reader for
that slot, and others that were missed perhaps, for the next release. Thanks
much...

Cheers, David

Subject: [Lisa-users] Rule docstrings


A useful undocumented feature of LISA is that rules can have a
documentation string.  But, as far as I know, there is no exported
function for later accessing it.  Here is a sample usage with the
contexts demo:

LISA-USER> (defrule frodo (:context :hobbits)
	     "Frodo fires and focuses on :wizards."
	     (frodo)
	     =>
	     (format t "frodo fired; focusing on :wizards.~%")
	     (assert (gandalf (name gandalf)))
	     (focus :wizards))
; Compiling LAMBDA NIL: 
; Compiling Top-Level Form: 
#<RULE HOBBITS.FRODO, CF is 0.000>
LISA-USER> (lisa::rule-comment *)
"Frodo fires and focuses on :wizards."
LISA-USER>
