From 9ab5748d0e93c84c36c5559a4cda2087b3a24560 Mon Sep 17 00:00:00 2001 From: Philip Kaludercic Date: Wed, 13 Sep 2023 12:26:22 +0200 Subject: [PATCH] Add the public API of Compat to the core * lisp/emacs-lisp/compat.el: Add stub file with minimal definitions, so that core packages, that haven't been installed from ELPA, can make use of the public API and use more recent function signatures. * lisp/progmodes/python.el (compat): Remove 'noerror flag, because Compat can now be required without the real package being available. --- lisp/emacs-lisp/compat.el | 61 +++++++++++++++++++++++++++++++++++++++ lisp/progmodes/python.el | 2 +- 2 files changed, 62 insertions(+), 1 deletion(-) create mode 100644 lisp/emacs-lisp/compat.el diff --git a/lisp/emacs-lisp/compat.el b/lisp/emacs-lisp/compat.el new file mode 100644 index 00000000000..4c60093b6be --- /dev/null +++ b/lisp/emacs-lisp/compat.el @@ -0,0 +1,61 @@ +;;; compat.el --- Pseudo-Compatibility for Elisp -*- lexical-binding: t; -*- + +;; Copyright (C) 2021-2023 Free Software Foundation, Inc. + +;; Author: \ +;; Philip Kaludercic , \ +;; Daniel Mendler +;; Maintainer: \ +;; Daniel Mendler , \ +;; Compat Development <~pkal/compat-devel@lists.sr.ht>, +;; emacs-devel@gnu.org +;; URL: https://github.com/emacs-compat/compat +;; Version: 1.0 +;; Keywords: lisp, maint + +;; This program 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. + +;; This program 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.
