repl-display-prompt, repl-display-result

Display a prompt/result in interactive mode

SYNOPSIS

(repl-display-prompt module)
(repl-display-result value)

DESCRIPTION

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))
