;;; dired-sort-menu+.el --- Extensions to `dired-sort-menu.el'
;;
;; Filename: dired-sort-menu+.el
;; Description: Extensions to `dired-sort-menu.el'
;; Author: Drew Adams
;; Maintainer: Drew Adams (concat "drew.adams" "@" "oracle" ".com")
;; Copyright (C) 2005-2018, Drew Adams, all rights reserved.
;; Created: Thu Jul 07 12:39:36 2005
;; Version: 0
;; Package-Requires: ((dired-sort-menu "0"))
;; Last-Updated: Fri Sep 21 13:38:59 2018 (-0700)
;; By: dradams
;; Update #: 140
;; URL: https://www.emacswiki.org/emacs/download/dired-sort-menu%2b.el
;; Doc URL: https://emacswiki.org/emacs/DiredSortMenu
;; Keywords: directories, diredp, dired
;; Compatibility: GNU Emacs: 20.x, 21.x, 22.x, 23.x, 24.x, 25.x, 26.x
;;
;; Features that might be required by this library:
;;
;; `dired', `dired-sort-menu', `easymenu', `wid-edit', `widget'.
;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;
;;; Commentary:
;;
;; Extensions to `dired-sort-menu.el'
;;
;; Francis J. Wright <F.J.Wright@maths.qmw.ac.uk> wrote library
;; `dired-sort-menu.el'
;; (https://www.emacswiki.org/emacs/dired-sort-menu.el, originally
;; http://centaur.maths.qmw.ac.uk/Emacs/).
;;
;; Library `dired-sort-menu+.el' modifies `dired-sort-menu.el' to play
;; better with other libraries from Drew Adams.
;;
;; Changes:
;;
;; 1. The toggles for reverse sorting, `ls-lisp-ignore-case' and
;; `ls-lisp-dirs-first', are bound respectively to "a", "c", and
;; "W" in the dired map, instead of "r", "c" and "b".
;;
;; 2. We don't define `dired-sort-menu-toggle-ignore-case' and
;; `dired-sort-menu-toggle-dirs-first' unless they can be used.
;;
;; 3. `handle-delete-frame' is protected against nil `buffer-name'.
;;
;;
;; ***** NOTE: The following functions defined in `dired.el' have
;; been REDEFINED or ADVISED HERE:
;;
;; `dired-sort-dialogue' -
;; 1. Fit frame. 2. Do not add `dired-sort-dialogue-auto-kill-1'
;; to `kill-buffer-hook'.
;; `dired-sort-dialogue-close' - Just `kill-buffer'.
;; `handle-delete-frame' - Do nothing if `buffer-name' is nil.
;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;
;;; Change Log:
;;
;; 2018/09/21 dadams
;; dired-sort-dialogue: Use pop-to-buffer-same-window, not switch-to-buffer.
;; 2011/06/18 dadams
;; Updated T prefix-key bindings, because added more in dired+.el.
;; 2011/04/19 dadams
;; Restore Dired+ bindings on prefix key T.
;; 2011/04/16 dadams
;; handle-delete-frame:
;; Fix for lexbind Emacs 24: replace named arg EVENT by (ad-get-arg 0).
;; 2005/11/05 dadams
;; Renamed dired+ stuff to have diredp- prefix.
;; 2005/11/02 dadams
;; Restore dired+ bindings messed up by dired-sort-menu.el.
;; Changed dired-sort-menu-toggle-reverse to "|" and
;; dired-sort-menu-toggle-dirs-first to "/".
;; 2005/07-26 dadams
;; Protected ls-lisp-var-p with fboundp.

;;; Commentary:
;; This package, which is intended for use with GNU Emacs 20/21,
;; implements a menu and a dialogue that consist of a set of radio
;; buttons and toggles to control sort order in dired mode. The menu
;; is added as a submenu to the Immediate menu, and bound to S-mouse-2
;; as a popup menu. The dialogue can be accessed via the menu or the
;; dired key binding `C-d' or the command `dired-sort-dialogue', which
;; *must* be run in a dired buffer! The dialogue uses the Emacs
;; widget library, which does not require GUI support but uses it if
;; available. The dialogue can be used with a character-based
;; display; the main keys to use are <TAB> and <RET> if a mouse is not
;; available or does not work. With a GUI the dialogue pops up its
;; own frame by default; otherwise it uses part of the dired window.
;; This is controlled by the customizable user option
;; `dired-sort-dialogue-own-frame'.
;; The menu and dialogue support the `ls' sort switches [tSXUucrR].
;; These are all implemented by GNU `ls'; the subset [tSucr] are
;; implemented by the standard Emacs 20 `ls-lisp' emulation and all
;; are implemented by the Emacs 21 `ls-lisp' (see above URL).
;; Changing a main sort option turns off reverse sorting; toggling
;; reverse sorting does not change the main sort option. Setting any
;; prefix argument before selecting a sort order reverses it
;; (e.g. press `C-u' or `C-number' or `M-number' BEFORE accessing the
;; menu bar). The menu also supports two Emacs 21 `ls-lisp' switches:
;; `ls-lisp-ignore-case' ignores case in alphanumeric sorts and
;; `ls-lisp-dirs-first' lists all directories first. (These latter
;; two switches improve compatibility with Microsoft Windows
;; Explorer.)
;; The toggles for reverse sorting, `ls-lisp-ignore-case' and
;; `ls-lisp-dirs-first', are bound respectively to the keys "r", "c"
;; and "b" in the dired map.
;; A `Configuration' submenu allows a dired sort configuration to be
;; saved or restored, the current and saved configurations to be
;; swaped (bound to "T" for "toggle"), or the default to be restored.
;; The saved configuration is saved as a customization, which can also
;; be changed directly. This submenu also allows
;; `dired-sort-dialogue-own-frame' to be toggled.
;; If a `dired-sort-menu' option causes an error (but not if it is
;; just ignored) then it is automatically disabled via the
;; customization facility. This is useful because not all `ls' and
;; `ftp' programs support the same sort options.
;; The dialogue allows the setting of arbitrary combinations of dired
;; sort options together, without requiring multiple menu accesses.
;; Each dired buffer has its own dialogue. This dialogue can be left
;; displayed, in which case it is automatically updated to reflect any
;; changes to its dired buffer that are made by other means. For
;; tidiness, a dialogue buffer is automatically killed whenever it or
;; its dired buffer becomes invisible.
;; To do:
;; test `dired-sort-menu-invalid-options' facility;
;; per-host `dired-sort-menu-invalid-options-remote';
;; cascade multiple dialogue frames?
;;; Installation:
;; Put this file somewhere where Emacs can find it (i.e. in one of the
