repl-display-prompt, repl-display-result
Display a prompt/result in
interactive mode
(repl-display-prompt module)
(repl-display-result value)
Repl-display-prompt is called by the interactive toplevel loop
before reading a sexpr. This procedure is called with one parameter:
the selected module in the toplevel loop.
A simple form of this procedure could be:
(define (repl-display-prompt module)
(let ((p (current-error-port)))
(format p "~A> " (module-name module))
(flush p)))
Repl-display-result is called by the interactive toplevel loop
after the evaluation of a sexpr. This procedure is called with the
result of this evaluation as parameter.
A simple form, mimicking the MIT Scheme way of presenting results, could be:
(define (repl-display-result value)
(format #t "\\n;Value: ~S\\n\\n" value))
