From 8e1664d108a183a9e1e53a3a42bc58a2a0104d60 Mon Sep 17 00:00:00 2001 From: Hong Xu Date: Sat, 6 Jul 2019 18:09:50 -0700 Subject: cmake-mode.el: Drop support for Emacs < 24 The `cmake--parent-mode` alias exists only for compatibility and breaks Emacs packages and scripts that make use of `prog-mode-hook` because Emacs does not examine whether the parent mode is an alias or not. Remove the alias and require Emacs 24 or higher. Emacs 24 was released in 2012 and this is already 2019, thus the loss to drop support for versions < 24 is negligible. --- Auxiliary/cmake-mode.el | 10 +++------- 1 file changed, 3 insertions(+), 7 deletions(-) diff --git a/Auxiliary/cmake-mode.el b/Auxiliary/cmake-mode.el index e4fa6c1..caaf0d5 100644 --- a/Auxiliary/cmake-mode.el +++ b/Auxiliary/cmake-mode.el @@ -1,5 +1,7 @@ ;;; cmake-mode.el --- major-mode for editing CMake sources +;; Package-Requires: ((emacs "24.1")) + ; Distributed under the OSI-approved BSD 3-Clause License.
