From: Chris Hanson Date: Thu, 28 Jan 1999 04:00:18 +0000 (+0000) Subject: Revamp of prompting code. New design supports keyword arguments to X-Git-Tag: 20090517-FFI~4681 X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=c5566269fa2ecdf4b5c211a221142b85717035e9;p=mit-scheme.git Revamp of prompting code. New design supports keyword arguments to most prompting procedures, to support options in an extensible way. The new keyword options are used to implement a general history mechanism, like that previously implemented by repeat-complex-command (which is now implemented using the new mechanism). This edit has made incompatible changes to the calling conventions of the following procedures: prompt-for-buffer-name prompt-for-expression prompt-for-pathname prompt-for-pathname* prompt-for-string prompt-for-completed-string prompt-for-string-table-name prompt-for-string-table-value --- diff --git a/v7/src/edwin/bufcom.scm b/v7/src/edwin/bufcom.scm index 7b0e2d142..3230f0921 100644 --- a/v7/src/edwin/bufcom.scm +++ b/v7/src/edwin/bufcom.scm @@ -1,6 +1,6 @@ ;;; -*-Scheme-*- ;;; -;;; $Id: bufcom.scm,v 1.105 1999/01/02 06:11:34 cph Exp $ +;;; $Id: bufcom.scm,v 1.106 1999/01/28 03:59:44 cph Exp $ ;;; ;;; Copyright (c) 1986, 1989-1999 Massachusetts Institute of Technology ;;; @@ -286,11 +286,11 @@ When locked, the buffer's major mode may not be changed."
