The stumpwm is built using clisp-2.49. The stumpwm evaling can display
the
result of the following function with the help of
"with-output-to-string":
(Maybe i is better to hack stumpwm to do such a thing as clfswm does)
(defun div618 (p1 p2)
(let ((ratio '(0. 0.191 0.236 0.382 0.5 0.618 0.809 1.))
(price #'(lambda (r) (if (<= p1 p2) (+ p1 (* (- p2 p1) r)) (-
p1
(* (- p1 p2) r))))))
(with-output-to-string (*standard-output*)
(if (<= p1 p2)
(dolist (r (reverse ratio)) (format t "-------~3$
~$-------~%" r (funcall price r)))
(dolist (r ratio) (format t "-------~3$ ~$-------~%" r
(funcall price r)))))))
However, both slime and stumpwm evaling cannot display the result of
(ext:shell "ls ~").
ext:shell output goes to filedescriptor 1, not even to *standard-output*
and CLisp offers no way to redirect this. There are other way to call
external programs with more freedom.
