(asdf:load-system "lisp-executable-example") (asdf:oos 'lisp-executable:create-executables-op "lisp-executable-example")
The above code will generate two executables,
(define-program example-program (&options help) (cond (help (format t "Help has arrived.")) (t (format t "You are doomed."))) (terpri))
(define-program control-c-tester (&options help (sleep sleep-time)) (declare (conversion-function (real 0) sleep) (type (or null (real 0)) sleep-time)) (unless sleep (setf sleep-time 20.0)) (cond (help (format t "Usage: [options] Sleep for an amount of time. Options: --help This helpful message. --sleep <positive real> How long to sleep for. Default is 20 seconds. ") 0) (t (sleep sleep-time) 0)))
