;; -*- Mode: Emacs-Lisp -*- ;; sc.el -- Version 2.3 (used to be supercite.el) ;; ========== Introduction ========== ;; Citation and attribution package for various GNU emacs news and ;; electronic mail reading subsystems. This version of supercite should ;; work with Rmail and GNUS as found in Emacs 19. It may also work with ;; VM 4.40+ and MH-E 3.7. ;; This package does not do any yanking of messages, but instead ;; massages raw reply buffers set up by the reply/forward functions in ;; the news/mail subsystems. Therefore, such useful operations as ;; yanking and citing portions of the original article (instead of the ;; whole article) are not within the ability or responsibility of ;; supercite. ;; ========== Disclaimer ========== ;; This software is distributed in the hope that it will be useful, ;; but WITHOUT ANY WARRANTY. No author or distributor, nor any ;; author's past, present, or future employers accepts responsibility ;; to anyone for the consequences of using it or for whether it serves ;; any particular purpose or works at all, unless he says so in ;; writing. ;; Some of this software was written as part of the supercite author's ;; official duty as an employee of the United States Government and is ;; thus not subject to copyright. You are free to use that particular ;; software as you wish, but WITHOUT ANY WARRANTY WHATSOEVER. It ;; would be nice, though if when you use any of this or other freely ;; available code, you give due credit to the author. ;; Other parts of this code were written by other people. Wherever ;; possible, credit to that author, and the copy* notice supplied by ;; the author are included with that code. The supercite author is no ;; longer an employee of the U.S. Government so the GNU Public Licence ;; should be considered in effect for all enhancements and bug fixes ;; performed by the author. ;; ========== Author (unless otherwise stated) ======================== ;; NAME: Barry A. Warsaw USMAIL: Century Computing, Inc. ;; TELE: (301) 593-3330 1014 West Street ;; INET: bwarsaw@cen.com Laurel, Md 20707 ;; UUCP: uunet!cen.com!bwarsaw ;; ;; Want to be on the Supercite mailing list? ;; ;; Send articles to: ;; Internet: supercite@anthem.nlm.nih.gov ;; UUCP: uunet!anthem.nlm.nih.gov!supercite ;; ;; Send administrivia (additions/deletions to list, etc) to: ;; Internet: supercite-request@anthem.nlm.nih.gov ;; UUCP: uunet!anthem.nlm.nih.gov!supercite-request ;; ========== Credits and Thanks ========== ;; This package was derived from the Superyank 1.11 package as posted ;; to the net. Superyank 1.11 was inspired by code and ideas from ;; Martin Neitzel and Ashwin Ram. Supercite version 2.3 has evolved ;; through the comments and suggestions of the supercite mailing list ;; which consists of many authors and users of the various mail and ;; news reading subsystems. ;; Many folks on the supercite mailing list have contributed their ;; help in debugging, making suggestions and supplying support code or ;; bug fixes for the previous versions of supercite. I want to thank ;; everyone who helped, especially (in no particular order): ;; ;; Mark D. Baushke, Khalid Sattar, David Lawrence, Chris Davis, Kyle ;; Jones, Kayvan Sylvan, Masanobu Umeda, Dan Jacobson, Piet van ;; Oostrum, Hamish (H.I.) Macdonald, and Joe Wells. ;; ;; I don't mean to leave anyone out. All who have helped have been ;; appreciated. ;; ========== Getting Started ========== ;; Here is a quick guide to getting started with supercite. The ;; information contained here is mostly excerpted from the more ;; detailed explanations given in the accompanying README file. ;; Naturally, there are many customizations you can do to give your ;; replies that personalized flair, but the instructions in this ;; section should be sufficient for getting started. ;; First, to connect supercite to any mail/news reading subsystem, put ;; this in your .emacs file: ;; ;; (setq mail-yank-hooks 'sc-cite-original) ; for old mail agents ;; (setq mh-yank-hooks 'sc-cite-original) ; for MH-E only ;; (add-hook 'mail-citation-hook 'sc-cite-original) ; for newer mail agents ;; ;; If supercite is not pre-loaded into your emacs session, you should ;; add the following autoload: ;; ;; (autoload 'sc-cite-original "sc" "Supercite 2.3" t) ;; ;; Finally, if you want to customize supercite, you should do it in a ;; function called my-supercite-hook and: ;; ;; (setq sc-load-hook 'my-supercite-hook) (require 'assoc) ;; vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv ;; start of user defined variables ;; vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv (defvar sc-nested-citation-p nil "*Controls whether to use nested or non-nested citation style.
