From 5297b361d1c5c7dd62b80da0327c091e4c23b140 Mon Sep 17 00:00:00 2001 From: Dmitry Kurochkin Date: Thu, 26 May 2011 20:27:58 +0400 Subject: test: add test-lib.el file with `visible-buffer-string' function The patch adds test-lib.el file for Emacs tests auxiliary stuff. Currently, it implements two functions: `visible-buffer-string' and `visible-buffer-substring'. These are similar to standard counterparts without "visible-" prefix but exclude invisible text. The functions are not used anywhere at the moment but should be useful for testing hiding/showing in the Emacs interface. Edited-by: Carl Worth Fixed "basic" test to ignore new test-lib.el file. --- test/test-lib.el | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 test/test-lib.el (limited to 'test/test-lib.el') diff --git a/test/test-lib.el b/test/test-lib.el new file mode 100644 index 00000000..94399962 --- /dev/null +++ b/test/test-lib.el @@ -0,0 +1,35 @@ +;; test-lib.el --- auxiliary stuff for Notmuch Emacs tests. +;; +;; Copyright © Carl Worth +;; Copyright © David Edmondson +;; +;; This file is part of Notmuch test suit. +;; +;; Notmuch is free software: you can redistribute it and/or modify it +;; under the terms of the GNU General Public License as published by +;; the Free Software Foundation, either version 3 of the License, or +;; (at your option) any later version. +;; +;; Notmuch is distributed in the hope that it will be useful, but +;; WITHOUT ANY WARRANTY; without even the implied warranty of +;; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
