Subject: bug#37086: Guile Ice-9 Readline with-readline-completion-function
Date: Mon, 19 Aug 2019 20:12:27 -0400	[thread overview]
Message-ID: <CAFZHh1qrZ6pEh3CA0Wm21MQKmj1JxXmgNVAv03vONncBVw6P0g@mail.gmail.com> (raw)
In-Reply-To: <CAFZHh1qSRxn6nVj4E0KAUFU2aXaAHdZ86cpv9EBgvqnSGrW0rQ@mail.gmail.com>

I'm early in my Scheme journey, but here's a suggested fix:

(define-syntax-rule (with-readline-completion-function completer expr ...)
  "With @var{completer} as readline completion function, call @var{expr ...}."
  (let ((old-completer *readline-completion-function*))
    (dynamic-wind
      (lambda ()
    (set! *readline-completion-function* completer))
      (lambda () expr ...)
      (lambda ()
    (set! *readline-completion-function* old-completer)))))

(export with-readline-completion-function)
