From 0a094fb65ca1392231ef8176f89f936e39f3296e Mon Sep 17 00:00:00 2001 From: dickmao Date: Sun, 20 Mar 2022 11:34:56 -0400 Subject: Rewrite hl-line-mode The fashion of dual global and minor modes, each managing a replica of state, has long been outmoded by globalized minor modes (nee easy-mmode-define-global-mode) around the turn of the century. * lisp/calendar/todo-mode.el (todo-toggle-item-highlighting, todo-hl-line-range, todo-modes-set-2): Adapt to new hl-line-highlight-hook. * lisp/hl-line.el (hl-line-overlay): Rename hl-line--overlay. (global-hl-line-overlay, global-hl-line-overlays, global-hl-line-sticky-flag, hl-line-overlay-buffer, hl-line-range-function): Obsolesce. (hl-line--overlay): Erstwhile hl-line-overlay. (hl-line, hl-line-face): Consolidate. (hl-line-sticky-flag): Say less (Gen Z Hospital). (hl-line-overlay-priority): Make this a custom. (hl-line-highlight-hook): Prefer hook over specialized hl-line-range-function. (hl-line-mode): Say less (Gen Z Hospital). (hl-line-make-overlay): Remove (hl-line-highlight, hl-line-unhighlight): Rewrite. (hl-line-maybe-unhighlight): Remove. (hl-line-turn-on): Necessary for globalized minor mode. (global-hl-line-mode, global-hl-line-highlight, global-hl-line-highlight-all, global-hl-line-unhighlight, global-hl-line-maybe-unhighlight, global-hl-line-unhighlight-all): Prefer globalized minor mode. (hl-line-move, hl-line-unload-function): Remove. * test/lisp/calendar/todo-mode-tests.el (todo-test-item-highlighting, todo-test-done-items-separator06-bol, todo-test-done-items-separator06-eol, todo-test-done-items-separator07): Adapt to consolidated face. --- test/lisp/hl-line-tests.el | 51 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 test/lisp/hl-line-tests.el (limited to 'test/lisp/hl-line-tests.el') diff --git a/test/lisp/hl-line-tests.el b/test/lisp/hl-line-tests.el new file mode 100644 index 00000000000..422d4ddae7d --- /dev/null +++ b/test/lisp/hl-line-tests.el @@ -0,0 +1,51 @@ +;;; hl-line-tests.el --- Test suite for hl-line. -*- lexical-binding: t -*- + +;; Copyright (C) 2022 Free Software Foundation, Inc. + +;; This file is part of GNU Emacs. + +;; GNU Emacs 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. + +;; GNU Emacs 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.
