Tweak Commentary (the code doesn't seem to provide the lambda prettification mentioned). (cl-font-lock-add-regexes): Remove macro. (cl-font-lock-built-in-keywords): New variable. (cl-font-lock-built-in-mode): New minor mode. --- diff --git a/lisp/progmodes/cl-font-lock.el b/lisp/progmodes/cl-font-lock.el index 6d6992e11c1..7ef43fd4490 100644 --- a/lisp/progmodes/cl-font-lock.el +++ b/lisp/progmodes/cl-font-lock.el @@ -1,52 +1,59 @@ ;;; cl-font-lock.el --- Pretty Common Lisp font locking -*- lexical-binding: t; -*- -;; Copyright (C) 2019 Yue Daian -;; Author: Yue Daian +;; Copyright (C) 2019-2020 Free Software Foundation, Inc. + +;; Author: Yue Daian ;; Maintainer: Spenser Truex ;; Created: 2019-06-16 -;; Version: 0.3.0 +;; Old-Version: 0.3.0 ;; Package-Requires: ((emacs "24.5")) ;; Keywords: lisp wp files convenience ;; URL: https://github.com/cl-font-lock/cl-font-lock ;; Homepage: https://github.com/cl-font-lock/cl-font-lock -;; This file is not part of GNU Emacs, but you want to use GNU Emacs to run it. -;; This file is very free software. - -;; This is free and unencumbered software released into the public domain. - -;; Anyone is free to copy, modify, publish, use, compile, sell, or -;; distribute this software, either in source code form or as a compiled -;; binary, for any purpose, commercial or non-commercial, and by any -;; means. -;; In jurisdictions that recognize copyright laws, the author or authors -;; of this software dedicate any and all copyright interest in the -;; software to the public domain.
