+;;; Commentary:
+;;
+;;    Extensions to Dired.
+;;
+;;  This file extends functionalities provided by standard GNU Emacs
+;;  files `dired.el', `dired-aux.el', and `dired-x.el'.
+;;
+;;  Key bindings changed.  Menus redefined.  `diredp-mouse-3-menu'
+;;  popup menu added.  New commands.  Some commands enhanced.
+;;
+;;  All of the new functions, variables, and faces defined here have
+;;  the prefix `diredp-' (for Dired Plus) in their names.
+;;
+;;
+;;  Wraparound Navigation
+;;  ---------------------
+;;
+;;  In vanilla Dired, `dired-next-marked-file' (`M-}' or `* C-n') and
+;;  `dired-previous-marked-file' (`M-{' or `* C-p') wrap around when
+;;  you get to the end or the beginning of the Dired buffer.  Handy.
+;;
+;;  But the other navigation commands do not wrap around.  In `Dired+'
+;;  they do, provided option `diredp-wrap-around-flag' is non-nil,
+;;  which it is by default.  This means the following commands:
+;;
+;;    `diredp-next-line'     - `n', `C-n', `down', `SPC'
+;;    `diredp-previous-line' - `p', `C-p', `up'
+;;    `diredp-next-dirline'  - `>'
+;;    `diredp-prev-dirline'  - `<'
+;;    `diredp-next-subdir'   - `C-M-n'
+;;    `diredp-prev-subdir'   - `C-M-p'
+;;
+;;
+;;  Quick Viewing While Navigating
+;;  ------------------------------
+;;
+;;  You can use key `C-down' or `C-up' to navigate to the next or
+;;  previous file line, respectively, and at the same time show its
+;;  file in another window.  The focus remains on the Dired buffer.
+;;  A numeric prefix arg means move that many lines first.
+;;
+;;  Names of files and directories that match either of the options
+;;  `diredp-visit-ignore-extensions' or `diredp-visit-ignore-regexps'
+;;  are skipped.
+;;
+;;  You can use `e' to show the file of the current line.  If it is
+;;  already shown in the same frame, and if Dired is the only other
+;;  window there, then the file is hidden (its window is deleted).
+;;
+;;
+;;  Font-Lock Highlighting
+;;  ----------------------
+;;
+;;  If you want a maximum or minimum fontification for Dired mode,
+;;  then customize option `font-lock-maximum-decoration'.  If you want
+;;  a different fontification level for Dired than for other modes,
+;;  you can do this too by customizing
+;;  `font-lock-maximize-decoration'.
+;;
+;;  A few of the user options defined here have an effect on
+;;  font-locking, and this effect is established only when Dired+ is
+;;  loaded, which defines the font-lock keywords for Dired.  These
+;;  options include `diredp-compressed-extensions',
+;;  `diredp-ignore-compressed-flag', `dired-omit-extensions', and
+;;  `diredp-omit-files-regexp'.  This means that if you change the
+;;  value of such an option then you will see the change only in a new
+;;  Emacs session.
+;;
+;;  (You can see the effect in the same session if you use `C-M-x' on
+;;  the `defvar' sexp for `diredp-font-lock-keywords-1', and then you
+;;  toggle font-lock off and back on.)
+;;
+;;
+;;  Act on All Files
+;;  ----------------
+;;
+;;  Most of the commands (such as `C' and `M-g') that operate on the
+;;  marked files have the added feature here that multiple `C-u' use
+;;  not the files that are marked or the next or previous N files, but
+;;  *all* of the files in the Dired buffer.  Just what "all" files
+;;  means changes with the number of `C-u', as follows:
+;;
+;;    `C-u C-u'         - Use all files present, but no directories.
+;;    `C-u C-u C-u'     - Use all files and dirs except `.' and `..'.
+;;    `C-u C-u C-u C-u' - use all files and dirs, `.' and `..'.
+;;
+;;    (More than four `C-u' act the same as two.)
+;;
+;;  This feature can be particularly useful when you have a Dired
+;;  buffer with files chosen from multiple directories.
+;;
+;;  Note that in most cases this behavior is described only in the doc
+;;  string of function `dired-get-marked-files'.  It is generally
+;;  *not* described in the doc strings of the various commands,
+;;  because that would require redefining each command separately
+;;  here.  Instead, we redefine macro `dired-map-over-marks' and
+;;  function `dired-get-filename' in order to achieve this effect.
+;;
+;;  Commands such as `dired-do-load' for which it does not make sense
+;;  to act on directories generally treat more than two `C-u' the same
+;;  as two `C-u'.
+;;
+;;  Exceptions to the general behavior described here are called out
+;;  in the doc strings.  In particular, the behavior of a prefix arg
+;;  for `dired-do-query-replace-regexp' is different, so that you can
+;;  use it also to specify word-delimited replacement.
+;;
+;;
+;;  Act on Marked (or All) Files Here and Below
+;;  -------------------------------------------
+;;
+;;  The prefix argument behavior just described does not apply to the
+;;  `diredp-*-recursive' commands.  These commands act on the marked
+;;  files in the current Dired buffer or on all files in the directory
+;;  if none are marked.
+;;
+;;  But these commands also handle marked subdirectories recursively,
+;;  in the same way.  That is, they act also on the marked files in
+;;  any marked subdirectories, found recursively.  If such a
+;;  descendant directory is listed in a Dired buffer then its marked
+;;  files and subdirs are handled the same way.  If there is no Dired
+;;  buffer that lists a given marked subdirectory then all of its
+;;  files and subdirs are acted on.
+;;
+;;  For most such here-and-below commands, a prefix argument means
+;;  ignore all marks.  The commands then act on all files in the
+;;  current Dired buffer and all of its subdirectories, recursively.
+;;
+;;  But here-and-below commands that unmark or change marks act
+;;  differently for different kinds of prefix argument:
+;;
+;;  * A non-positive prefix arg means ignore subdir markings and act
+;;    instead on ALL subdirs.
+;;
+;;  * A non-negative prefix arg means do not change marks on subdirs
+;;    themselves.
+;;
+;;  For example, `M-+ U' removes all marks, including from marked
+;;  subdirs, recursively.  `C-- M-+ U' removes them from all files in
+;;  all subdirs (marked or not), recursively.  `C-9 M-+ U' removes all
+;;  marks, recursively, except the marks on subdirs themselves.  `C-0
+;;  M-+ U' acts like those two combined: it descends everywhere,
+;;  ignoring which subdirs are marked, but it does not remove marks
+;;  from subdirs themselves.
+;;
+;;  All of the `diredp-*-recursive' commands are on prefix key `M-+',
+;;  and most are available on submenu `Marked Here and Below' of the
+;;  `Multiple' menu-bar menu.  The commands that unmark and change
+;;  marks are also in submenu `Here and Below' of menu-bar menu
+;;  `Marks'.
+;;
+;;  If you use library `Icicles' then you have the following
+;;  additional commands/keys that act recursively on marked files.
+;;  They are in the `Icicles' submenu of menu `Multiple' > `Marked
+;;  Here and Below'.
+;;
+;;  * `M-+ M-s M-s' or `M-s M-s m' - Use Icicles search (and its
+;;                  on-demand replace) on the marked files.
+;;
+;;  * Save the names of the marked files:
+;;
+;;    `M-+ C-M->' - Save as a completion set, for use during
+;;                  completion (e.g. with `C-x C-f').
+;;
+;;    `M-+ C->'   - Add marked names to the names in the current saved
+;;                  completion set.
+;;
+;;    `M-+ C-}'   - Save persistently to an Icicles cache file, for
+;;                  use during completion in another session.
+;;
+;;    `icicle-dired-save-marked-to-fileset-recursive' - Like `M-+
+;;                  C-}', but save persistently to an Emacs fileset.
+;;
+;;    `M-+ C-M-}' - Save to a Lisp variable.
+;;
+;;
+;;  In the other direction, if you have a saved set of file names then
+;;  you can use `C-M-<' (`icicle-dired-chosen-files-other-window') in
+;;  Dired to open a Dired buffer for just those files.  So you can
+;;  mark some files and subdirs in a hierarchy of Dired buffers, use
+;;  `M-+ C-}' to save their names persistently, then later use `C-{'
+;;  to retrieve them, and `C-M-<' (in Dired) to open Dired on them.
+;;
+;;
+;;  Image Files
+;;  -----------
+;;
+;;  `Dired+' provides several enhancements regarding image files.
+;;  Most of these require standard library `image-dired.el'.  One of
+;;  them, command `diredp-do-display-images', which displays all of
+;;  the marked image files, requires standard library `image-file.el'.
+;;
+;;  `Dired+' loads these libraries automatically, if available, which
+;;  means an Emacs version that supports image display (Emacs 22 or
+;;  later).  (You must of course have installed whatever else your
+;;  Emacs version needs to display images.)
+;;
+;;  Besides command `diredp-do-display-images', see the commands whose
+;;  names have prefix `diredp-image-'.  And see options
+;;  `diredp-image-preview-in-tooltip' and
+;;  `diredp-auto-focus-frame-for-thumbnail-tooltip-flag'.
+;;    
+;;
+;;  Inserted Subdirs, Multiple Dired Buffers, Files from Anywhere,...
+;;  -----------------------------------------------------------------
+;;
+;;  These three standard Dired features are worth pointing out.  The
+;;  third in particular is little known because (a) it is limited in
+;;  vanilla Dired and (b) you cannot use it interactively.
+;;
+;;   * You can pass a glob pattern with wildcards to `dired'
+;;     interactively, as the file name.
+;;
+;;   * You can insert multiple subdirectory listings into a single
+;;     Dired buffer using `i' on each subdir line.  Use `C-u i' to
+;;     specify `ls' switches.  Specifying switch `R' inserts the
+;;     inserted subdirectory's subdirs also, recursively.  You can
+;;     also use `i' to bounce between a subdirectory line and its
+;;     inserted-listing header line.  You can delete a subdir listing
+;;     using `C-u k' on its header line.  You can hide/show an
+;;     inserted subdir using `$'.  You can use `C-_' to undo any of
+;;     these operations.
+;;
+;;   * You can open a Dired buffer for an arbitrary set of files from
+;;     different directories.  You do this by invoking `dired'
+;;     non-interactively, passing it a cons of a Dired buffer name and
+;;     the file names.  Relative file names are interpreted relative
+;;     to the value of `default-directory'.  Use absolute file names
+;;     when appropriate.
+;;
+;;  `Dired+' makes these features more useful.
+;;
+;;  `$' is improved: It is a simple toggle - it does not move the
+;;  cursor forward.  `M-$' advances the cursor, in addition to
+;;  toggling like `$'.  `C-u $' does hide/show all (what `M-$' does in
+;;  vanilla Dired).
+;;
+;;  `i' is improved in these ways:
+;;
+;;   * Once a subdir has been inserted, `i' bounces between the subdir
+;;     listing and the subdir line in the parent listing.  If the
+;;     parent dir is hidden, then `i' from a subdir opens the parent
+;;     listing so it can move to the subdir line there (Emacs 24+).
+;;
+;;   * Vanilla Dired lets you create a Dired listing with files and
+;;     directories from arbitrary locations, but you cannot insert
+;;     (`i') such a directory if it is not in the same directory tree
+;;     as the `default-directory' used to create the Dired buffer.
+;;     `Dired+' removes this limitation; you can insert any non-root
+;;     directories (that is, not `/', `c:/', etc.).
+;;
+;;  `Dired+' lets you create Dired buffers that contain arbitrary
+;;  files and directories interactively, not just using Lisp.  Just
+;;  use a non-positive prefix arg (e.g., `C--') when invoking `dired'.
+;;
+;;  You are then prompted for the Dired buffer name (anything you
+;;  like, not necessarily a directory name) and the individual files
+;;  and directories that you want listed.
+;;
+;;  A non-negative prefix arg still prompts you for the `ls' switches
+;;  to use.  (So `C-0' does both: prompts for `ls' switches and for
+;;  the Dired buffer name and the files to list.)
+;;
+;;  `Dired+' adds commands for combining and augmenting Dired
+;;  listings:
+;;
+;;   * `diredp-add-to-dired-buffer', bound globally to `C-x D A', lets
+;;     you add arbitrary file and directory names to an existing Dired
+;;     buffer.
+;;
+;;   * `diredp-dired-union', bound globally to `C-x D U', lets you
+;;     take the union of multiple Dired listings, or convert an
+;;     ordinary Dired listing to an explicit list of absolute file
+;;     names.  With a non-positive prefix arg, you can add extra file
+;;     and directory names, just as for `diredp-add-to-dired-buffer'.
+;;
+;;  You can optionally add a header line to a Dired buffer using
+;;  toggle command `diredp-breadcrumbs-in-header-line-mode'.  (A
+;;  header line remains at the top of the window - no need to scroll
+;;  to see it.)  If you want to show the header line automatically in
+;;  all Dired buffers, you can do this:
+;;
+;;    (add-hook 'dired-before-readin-hook
+;;              'diredp-breadcrumbs-in-header-line-mode)
+;;
+;;  Some other libraries, such as `Bookmark+' and `Icicles', make it
+;;  easy to create or re-create Dired buffers that list specific files
+;;  and have a particular set of markings.  `Bookmark+' records Dired
+;;  buffers persistently, remembering `ls' switches, markings, subdir
+;;  insertions, and hidden subdirs.  If you use `Icicles' then `dired'
+;;  is a multi-command: you can open multiple Dired buffers with one
+;;  `dired' invocation.
+;;
+;;  Dired can help you manage projects.  You might have multiple Dired
+;;  buffers with quite specific contents.  You might have some
+;;  subdirectories inserted in the same Dired buffer, and you might
+;;  have separate Dired buffers for some subdirectories.  Sometimes it
+;;  is useful to have both for the same subdirectory.  And sometimes
+;;  it is useful to move from one presentation to the other.
+;;
+;;  This is one motivation for the `Dired+' `diredp-*-recursive'
+;;  commands, which act on the marked files in marked subdirectories,
+;;  recursively.  In one sense, these commands are an alternative to
+;;  using a single Dired buffer with inserted subdirectories.  They
+;;  let you use the same operations on the files in a set of Dired
+;;  directories, without inserting those directories into an ancestor
+;;  Dired buffer.
+;;
+;;  You can use command `diredp-dired-inserted-subdirs' to open a
+;;  separate Dired buffer for each of the subdirs that is inserted in
+;;  the current Dired buffer.  Markings and Dired switches are
+;;  preserved.
+;;
+;;  In the opposite direction, if you use `Icicles' then you can use
+;;  multi-command `icicle-dired-insert-as-subdir', which lets you
+;;  insert any number of directories you choose interactively into a
+;;  Dired ancestor directory listing.  If a directory you choose to
+;;  insert already has its own Dired buffer, then its markings and
+;;  switches are preserved for the new, subdirectory listing in the
+;;  ancestor Dired buffer.
+;;
+;;
+;;  Hide/Show Details
+;;  -----------------
+;;
+;;  Starting with Emacs 24.4, listing details are hidden by default.
+;;  Note that this is different from the vanilla Emacs behavior, which
+;;  is to show details by default.
+;;
+;;  Use `(' anytime to toggle this hiding.  You can use option
+;;  `diredp-hide-details-initially-flag' to change the default/initial
+;;  state.  See also option `diredp-hide-details-propagate-flag'.
+;;
+;;  NOTE: If you do not want to hide details initially then you must
+;;        either (1) change `diredp-hide-details-initially-flag' using
+;;        Customize (recommended) or (2) set it to `nil' (e.g., using
+;;        `setq') *BEFORE* loading `dired+.el'.
+;;
+;;  If you have an Emacs version older than 24.4, you can use library
+;;  `dired-details+.el' (plus `dired-details.el') to get similar
+;;  behavior.
+;;
+;;
+;;  Mode-Line
+;;  ---------
+;;
+;;  The number of files and dirs that are marked with `*', and the
+;;  number that are flagged for deletion (marked `D') are indicated in
+;;  the mode-line.  When the cursor is on such a line the indication
+;;  tells you how many more there are.  For example, if the cursor is
+;;  on the line of the third file that is marked `*', and there are
+;;  seven of them total, then the mode-line shows `3/7*'.
+;;
+;;  The mode-line also indicates, for the current listing (which could
+;;  be a subdir listing), how many files and dirs are listed.  If the
+;;  cursor is on the 27th file in a listing of 78 files then the
+;;  mode-line shows 27/78.
+;;
+;;  For counting files and dirs in a listing, option
+;;  `diredp-count-.-and-..-flag' controls whether to count the lines
+;;  for `.' and `..'.  By default it is nil, meaning they are not
+;;  counted.
+;;
+;;
+;;  If You Use Dired+ in Terminal Mode
+;;  ----------------------------------
+;;
+;;  By default, Dired+ binds some keys that can be problematic in some
+;;  terminals when you use Emacs in terminal mode (i.e., `emacs -nw').
+;;  This is controlled by option
+;;  `diredp-bind-problematic-terminal-keys'.
+;;
+;;  In particular, keys that use modifiers Meta and Shift together can
+;;  be problematic.  If you use Dired+ in text-only terminal, and you
+;;  find that your terminal does not support such keys, then you might
+;;  want to customize the option to set the value to `nil', and then
+;;  bind the commands to some other keys, which your terminal
+;;  supports.
+;;  
+;;  The problematic keys used by Dired+ include these:
+;;
+;;    `M-M'   (aka `M-S-m')   - `diredp-chmod-this-file'
+;;    `M-O'   (aka `M-S-o')   - `diredp-chown-this-file'
+;;    `M-T'   (aka `M-S-t')   - `diredp-touch-this-file'
+;;    `C-M-B' (aka `C-M-S-b') - `diredp-do-bookmark-in-bookmark-file'
+;;    `C-M-G' (aka `C-M-S-g') - `diredp-chgrp-this-file'
+;;    `C-M-R' (aka `C-M-S-r') - `diredp-toggle-find-file-reuse-dir'
+;;    `C-M-T' (aka `C-M-S-t') - `dired-do-touch'
+;;    `M-+ M-B'   (aka `M-+ M-S-b') -
+;;        `diredp-do-bookmark-dirs-recursive'
+;;    `M-+ C-M-B' (aka `M-+ C-M-S-b') -
+;;        `diredp-do-bookmark-in-bookmark-file-recursive'
+;;    `M-+ C-M-T' (aka `M-+ C-M-S-t') - `diredp-do-touch-recursive'
+;;
+;;  (See also `(info "(org) TTY keys")' for more information about
+;;  keys that can be problematic in a text-only terminal.)

+  "Interactively, a prefix argument changes the behavior as follows:
+
+* If >= 0, you are first prompted for the `ls' switches to use.
+
+* If <= 0, you are prompted first for the name of the Dired  buffer.
+  Then you are prompted repeatedly for the names of the directories
+  or files to list in the buffer.  You can use file-name wildcards
+  (i.e., `*' for globbing), to include the matching files and
+  directories.  Use `C-g' to end.
+
+  In other words, instead of listing a single directory, the Dired
+  buffer can list any number of directories and file names, which can
+  even belong to different directory trees.
+
+The rest of this description applies only if you use Icicles.
+
+In Icicle mode this is a multi-command: You can cycle among file-name
+completion candidates and act individually on those that name
+directories.  The action is to open Dired for the directory.  While
+cycling, these keys are active:
+
+\\<minibuffer-local-completion-map>\
+`C-mouse-2', `C-return' - Act on current completion candidate only
+`C-down', `C-wheel-down' - Move to next completion candidate and act
+`C-up', `C-wheel-up' - Move to previous completion candidate and act
+`C-next'  - Move to next apropos-completion candidate and act
+`C-prior' - Move to previous apropos-completion candidate and act
+`C-end'   - Move to next prefix-completion candidate and act
+`C-home'  - Move to previous prefix-completion candidate and act
+`\\[icicle-all-candidates-action]'     - Act on *all* candidates, successively (careful!)
+`\\[icicle-all-candidates-list-alt-action]'     - Open Dired on all candidates
+
+When candidate action and cycling are combined (e.g. `C-next'), user
+option `icicle-act-before-cycle-flag' determines which occurs first.
+
+With prefix `C-M-' instead of `C-', the same keys (`C-M-mouse-2',
+`C-M-RET', `C-M-down', and so on) provide help about candidates.
+
+Use `mouse-2', `RET', or `S-RET' to finally choose a candidate, or
+`C-g' to quit.
+
+These keys are also bound in the minibuffer during completion (`*'
+means the key requires library `Bookmark+'):
+
+   S-delete    - Delete candidate file or (empty) dir
+   C-c +       - Create a new directory
+   C-backspace - Go up one directory level
+ * C-x C-t *   - Narrow to files with all of the tags you specify
+ * C-x C-t +   - Narrow to files with some of the tags you specify
+ * C-x C-t % * - Narrow to files with all tags matching a regexp
+ * C-x C-t % + - Narrow to files with some tags  matching a regexp
+ * C-x a +     - Add tags to the current-candidate file
+ * C-x a -     - Remove tags from the current-candidate file

+With a non-negative prefix arg, you are prompted for `ls' switches.
+With a non-positive prefix arg, you are prompted for file and dir
+names to add to the listing - see below.
+
+You are prompted for the name of the Dired union buffer.  Completion
+against names of existing Dired buffers is available, but you can
+enter any other name to create a new Dired buffer of that name.
+
+If the union buffer name you choose names an existing Dired buffer,
+then what happens depends on whether that buffer is an ordinary Dired
+directory listing or a list of arbitrary file names.  That is, it
+depends on whether `dired-directory' is a directory name or a cons of
+a Dired buffer name plus file names.
+
+* If the buffer is an ordinary Dired listing, then it is converted to
+  an explicit list of absolute file names, just as if these had been
+  chosen individually.  The existing buffer and window are replaced by
+  new ones that show the explicit listing.  (This replacement is
+  necessary because the list of files contained in an ordinary Dired
+  listing cannot be modified.)
+
+* If the buffer lists arbitrary file names explicitly, then it is
+  updated to include also the files from any Dired buffers and any
+  additional files that you specify.
+
+If the union buffer name you choose does not name an existing Dired
+buffer, then its `default-directory' is the same as the
+`default-directory' before invoking the command.
+
+If you use a non-positive prefix arg, then you can next choose
+additional file and directory names to add to the listing.  Use `C-g'
+when done choosing them.
+
+Any directory names you choose this way are included as single entries
+in the listing - the directory contents are not included (these
+directories are not unioned).  To instead include the contents of a
+directory chosen this way, use a glob pattern: `/*' after the
+directory name.
+
+You are then prompted for the Dired buffers to union.  Use `C-g' when
+done choosing them.  These Dired listings to union are included in the
+order that you chose them, and each entry is listed only once in the
+new Dired buffer.
+
+The new Dired listing respects the markings, subdirectory insertions,
+and hidden subdirectories of the selected Dired listings.  However, in
+case of conflict between marked or unmarked status for the same entry,
+the entry is marked.  Similarly, in case of conflict over an included
+subdirectory between it being hidden or shown, it is hidden, but its
+contained files are also listed.

+A non-negative prefix arg means to unmark those files instead.
+
+A non-positive prefix arg means to ignore subdir markings and act

+
+PREDICATE is a lisp sexp that can refer to the following symbols as
+variables:
+
+    `mode'   [string]  file permission bits, e.g. \"-rw-r--r--\"
+    `nlink'  [integer] number of links to file
+    `size'   [integer] file size in bytes
+    `uid'    [string]  owner
+    `gid'    [string]  group (If the gid is not displayed by `ls',
+                       this will still be set (to the same as uid))
+    `time'   [string]  the time that `ls' displays, e.g. \"Feb 12 14:17\"
+    `name'   [string]  the name of the file
+    `sym'    [string]  if file is a symbolic link, the linked-to name,
+                       else \"\"
+    `inode'  [integer] the inode of the file (only for `ls -i' output)
+    `blks'   [integer] the size of the file for `ls -s' output
+                       (ususally in blocks or, with `-k', in Kbytes)
+Examples:
+  Mark zero-length files: `(equal 0 size)'
+  Mark files last modified on Feb 2: `(string-match \"Feb  2\" time)'
+  Mark uncompiled Emacs Lisp files (`.el' file without a `.elc' file):
+     First, Dired just the source files: `dired *.el'.
+     Then, use \\[diredp-mark-sexp-recursive] with this sexp:
+          (not (file-exists-p (concat name \"c\")))
+
+There's an ambiguity when a single integer not followed by a unit
+prefix precedes the file mode: It is then parsed as inode number
+and not as block size (this always works for GNU coreutils ls).
+
+Another limitation is that the uid field is needed for the
+function to work correctly.  In particular, the field is not
+present for some values of `ls-lisp-emulation'.
+
+This function operates only on the Dired buffer content.  It does not
+refer at all to the underlying file system.  Contrast this with
+`find-dired', which might be preferable for the task at hand.

+;;;;;;
+;;;;;; 1. This incorporates the `dired-x.el' change to the `dired.el'
+;;;;;;    definition.  This version works with or without using dired-x.
+;;;;;;    The `dired-x.el' version respects the var `dired-find-subdir'.
+;;;;;;    When `dired-find-subdir' is non-nil, this version is the same
+;;;;;;    as the `dired-x.el' version, except that a bug is corrected:
+;;;;;;    Whenever the argument to `dired-find-buffer-nocreate' is a cons,
+;;;;;;    the call to `dired-buffers-for-dir' gave a wrong type error.
+;;;;;;    This has been avoided by not respecting `dired-find-subdir'
+;;;;;;    whenever `dired-find-buffer-nocreate' is a cons.
+;;;;;;    For the case when `dired-find-subdir' is nil, see #2, below.
+;;;;;;
+;;;;;; 2. Unless `dired-find-subdir' is bound and non-nil:
+;;;;;;    If both DIRNAME and `dired-directory' are conses, then only
+;;;;;;    compare their cars (directories), not their explicit file lists
+;;;;;;    too.  If equal, then update `dired-directory's file list to that
+;;;;;;    of DIRNAME.
+;;;;;;
+;;;;;;    This prevents `dired-internal-noselect' (which is currently
+;;;;;;    `dired-find-buffer-nocreate's only caller) from creating a new
+;;;;;;    buffer in this case whenever a different set of files is present
+;;;;;;    in the cdr of DIRNAME and DIRNAME represents the same buffer as
+;;;;;;    `dired-directory'.
+;;;;;;
+;;;;;;    If only one of DIRNAME and `dired-directory' is a cons, then

+`.' and `..' are never marked or unmarked by this command.
+
+Whether to mark or unmark, and what form of file name to match, are
+governed by the prefix argument.  For this, a plain (`C-u') or a
+double-plain (`C-u C-u') prefix arg is considered only as such - it is
+not considered numerically.
+
+Whether to mark or unmark:
+
+ - No prefix arg, a positive arg, or a negative arg means mark.
+
+ - Plain (`C-u'), double-plain (`C-u C-u'), or zero (e.g. `M-0' means
+   unmark.
+
+The form of a file name used for matching:
+
+ - No prefix arg (to mark) or a plain prefix arg (`C-u', to unmark)
+   means use the relative file name (no directory part).
+
+ - A negative arg (e.g. `M--', to mark) or a zero arg (e.g. `M-0', to
+   unmark) means use the absolute file name, that is, including all
+   directory components.
+
+ - A positive arg (e.g. `M-+', to mark) or a double plain arg (`C-u
+   C-u', to unmark) means construct the name relative to
+   `default-directory'.  For an entry in an inserted subdir listing,
+   this means prefix the relative file name (no directory part) with
+   the subdir name relative to `default-directory'.
+
+Note that the default matching behavior of this command is different
+for Dired+ than it is for vanilla Emacs.  Using a positive prefix arg
+or a double plain prefix arg (`C-u C-u') gives you the same behavior
+as vanilla Emacs (marking or unmarking, respectively): matching
+against names that are relative to the `default-directory'.
+
+What Dired+ offers in addition is the possibility to match against
+names that are relative (have no directory part - no prefix arg or
+`C-u' to mark and unmark, respectively) or absolute (`M--' or `M-0',
+respectively).  The default behavior uses relative names because this
+is likely to be the more common use case.  But matching against
+absolute names gives you more flexibility.
+
+REGEXP is an Emacs regexp, not a shell wildcard.  Thus, use `\\.o$'
+for object files--just `.o' might mark more than you might expect.
+
+REGEXP is added to `regexp-search-ring', for regexp search.
+
+Non-interactively:
+ MARKER-CHAR is the marker character - used for `dired-marker-char'.
+ LOCALP is passed to `dired-get-filename'.  It determines the form of

+PREDICATE is a lisp sexp that can refer to the following symbols as

+
+    `mode'   [string]  file permission bits, e.g. \"-rw-r--r--\"
+    `nlink'  [integer] number of links to file
+    `size'   [integer] file size in bytes
+    `uid'    [string]  owner
+    `gid'    [string]  group (If the gid is not displayed by `ls',
+                       this will still be set (to the same as uid))
+    `time'   [string]  the time that `ls' displays, e.g. \"Feb 12 14:17\"
+    `name'   [string]  the name of the file
+    `sym'    [string]  if file is a symbolic link, the linked-to name,
+                       else \"\"
+    `inode'  [integer] the inode of the file (only for `ls -i' output)
+    `blks'   [integer] the size of the file for `ls -s' output
+                       (ususally in blocks or, with `-k', in Kbytes)
+Examples:
+  Mark zero-length files: `(equal 0 size)'
+  Mark files last modified on Feb 2: `(string-match \"Feb  2\" time)'
+  Mark uncompiled Emacs Lisp files (`.el' file without a `.elc' file):
+     First, Dired just the source files: `dired *.el'.
+     Then, use \\[dired-mark-sexp] with this sexp:
+          (not (file-exists-p (concat name \"c\")))
+
+There's an ambiguity when a single integer not followed by a unit
+prefix precedes the file mode: It is then parsed as inode number
+and not as block size (this always works for GNU coreutils ls).
+
+Another limitation is that the uid field is needed for the
+function to work correctly.  In particular, the field is not
+present for some values of `ls-lisp-emulation'.
+
+This function operates only on the Dired buffer content.  It does not
+refer at all to the underlying file system.  Contrast this with
+`find-dired', which might be preferable for the task at hand."

+;;; alist.el --- Interface for working with associative lists -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; Firstly, a rant:
+;; In most cases, I find Elisp's APIs to be confusing.  There's a mixture of
+;; overloaded functions that leak the implementation details (TODO: provide an
+;; example of this.) of the abstract data type, which I find privileges those
+;; "insiders" who spend disproportionately large amounts of time in Elisp land,
+;; and other functions with little-to-no pattern about the order in which
+;; arguments should be applied.  In theory, however, most of these APIs could
+;; and should be much simpler.  This module represents a step in that direction.
+;;
+;; I'm modelling these APIs after Elixir's APIs.
+;;
+;; On my wishlist is to create protocols that will allow generic interfaces like
+;; Enum protocols, etc.  Would be nice to abstract over...
+;; - associative lists (i.e. alists)
+;; - property lists (i.e. plists)
+;; - hash tables
+;; ...with some dictionary or map-like interface.  This will probably end up
+;; being quite similar to the kv.el project but with differences at the API
+;; layer.
+;;
+;; Similar libraries:
+;; - map.el: Comes bundled with recent versions of Emacs.
+;; - asoc.el: Helpers for working with alists.  asoc.el is similar to alist.el
+;;   because it uses the "!" convention for signalling that a function mutates
+;;   the underlying data structure.
+;; - ht.el: Hash table library.
+;; - kv.el: Library for dealing with key-value collections.  Note that map.el
+;;   has a similar typeclass because it works with lists, hash-tables, or
+;;   arrays.
+;; - a.el: Clojure-inspired way of working with key-value data structures in
+;; Elisp.  Works with alists, hash-tables, and sometimes vectors.
+;;
+;; Some API design principles:
+;; - The "noun" (i.e. alist) of the "verb" (i.e. function) comes last to improve
+;; composability with the threading macro (i.e. `->>') and to improve consumers'
+;; intuition with the APIs.  Learn this once, know it always.
+;;
+;; - Every function avoids mutating the alist unless it ends with !.
+;;
+;; - CRUD operations will be named according to the following table:
+;;   - "create" *and* "set"
+;;   - "read"   *and* "get"
+;;   - "update"
+;;   - "delete" *and* "remove"
+;;
+;; For better or worse, all of this code expects alists in the form of:
+;; ((first-name . "William") (last-name . "Carroll"))
+;;
+;; Special thanks to github.com/alphapapa/emacs-package-dev-handbook for some of
+;; the idiomatic ways to update alists.
+;;
+;; TODO: Include a section that compares alist.el to a.el from
+;; github.com/plexus/a.el.
+
+;; Dependencies:
+
+;; TODO: Consider dropping explicit dependency white-listing since all of these
+;; should be available in my Emacs.  The problem arises when this library needs
+;; to be published, in which case, something like Nix and a build process could
+;; possible insert the necessary require statements herein.  Not sure how I feel
+;; about this though.

+;; allowing duplicates the whole thing with Sets?  Kind of.  But the interface
+;; of Sets is something that bags resemble, so multi-set isn't as bag of a name
+;; as it may first seem.
+;;
+;; If you've used Python's collections.Counter, the concept of a bag should be
+;; familiar already.
+;;
+;; Interface:
+;; - add        :: x -> Bag(x) -> Bag(x)
+;; - remove     :: x -> Bag(x) -> Bag(x)
+;; - union      :: Bag(x) -> Bag(x) -> Bag(x)

+;; Author: William Carroll <wpcarro@gmail.com>

+;;; Commentary:
+;; An immutable cache data structure.
+;;
+;; This is like a sideways stack, that you can pull values out from and re-push
+;; to the top.  It'd be like a stack supporting push, pop, pull.
+;;
+;; This isn't a key-value data-structure like you might expect from a
+;; traditional cache.  The name is subject to change, but the underlying idea of
+;; a cache remains the same.
+;;
+;; Think about prescient.el, which uses essentially an LRU cache integrated into
+;; counsel to help create a "clairovoyant", self-organizing list.
+;;
+;; Use-cases:
+;; - Keeps an cache of workspaces sorted as MRU with an LRU eviction strategy.

+;;; do.el --- Small assertion library for Elisp -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; Assertion library inspired by Elixir's core testing library.
+;;
+;; The goal here is to create this module without relying on other non-core
+;; Elisp libraries.  I will attempt to do this as long as I'm not sacrificing
+;; the readability of this code nor the ease at which it can be written.
+;;
+;; A note on testing:
+;; Another goal with this library is to blur the line between testing code and
+;; runtime code.  Developers should ideally be using `do/assert' and `do/refute'
+;; in their library code.  Because of this, I'm avoiding referring
+;; to the notion of testing in the names of these functions.
+;;
+;; Hypothesis:
+;; The lower the friction is for writing tests, the more likely people will
+;; write tests.
+
+;; TODO: Support better error messages, which might include information about
+;; line numbers in source code where the assertion failed.
+
+;; TODO: Consider offering the ability to have some of these functions compile
+;; to nothing at runtime if developers want to use them while developing without
+;; incurring the costs at runtime.
+
+;; TODO: Consider using this module instead of prelude.el.  Right now, I'm
+;; having troubling preferring one to the other.  The benefit of this module is
+;; that it's independent of prelude, but that might also be a downside, since
+;; the messaging that asserting should be a critical part of any core library
+;; like prelude.

+;;; ivy-clipmenu.el --- Emacs client for clipmenu -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; Ivy integration with the clipboard manager, clipmenu.  Essentially, clipmenu
+;; turns your system clipboard into a list.
+;;
+;; To use this module, you must first install clipmenu and ensure that the
+;; clipmenud daemon is running.  Refer to the installation instructions at
+;; github.com/cdown/clipmenu for those details.
+;;
+;; This module intentionally does not define any keybindings since I'd prefer
+;; not to presume my users' preferences.  Personally, I use EXWM as my window
+;; manager, so I call `exwm-input-set-key' and map it to `ivy-clipmenu/copy'.
+;;
+;; Usually clipmenu integrates with rofi or dmenu.  This Emacs module integrates
+;; with ivy.  Launch this when you want to select a clip.
+;;
+;; Clipmenu itself supports a variety of environment variables that allow you to
+;; customize its behavior.  These variables are respected herein.  If you'd
+;; prefer to customize clipmenu's behavior from within Emacs, refer to the
+;; variables defined in this module.
+;;
+;; For more information:
+;; - See `clipmenu --help`.
+;; - Visit github.com/cdown/clipmenu.

+;;; list.el --- Functions for working with lists. -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; Since I prefer having the `list/' namespace, I wrote this module to wrap many
+;; of the functions that are defined in the the global namespace in ELisp.  I
+;; sometimes forget the names of these functions, so it's nice for them to be
+;; organized like this.
+;;
+;; Motivation:
+;; Here are some examples of function names that I cannot tolerate:
+;; - `car': Return the first element (i.e. "head") of a linked list
+;; - `cdr': Return the tail of a linked list
+
+;; As are most APIs for standard libraries that I write, this is heavily
+;; influenced by Elixir's standard library.
+;;
+;; Elixir's List library:
+;; - ++/2
+;; - --/2
+;; - hd/1
+;; - tl/1
+;; - in/2
+;; - length/1
+;;
+;; Similar libraries:
+;; - dash.el: Functional library that mimmicks Clojure.  It is consumed herein.
+;; - list-utils.el: Utility library that covers things that dash.el may not
+;;   cover.
+;;   stream.el: Elisp implementation of streams, "implemented as delayed
+;;   evaluation of cons cells."
+
+;; TODO: Consider naming this file linked-list.el.
+
+;; TODO: Support module-like macro that auto-namespaces functions.
+
+;; TODO: Consider wrapping most data structures like linked-lists,
+;; associative-lists, etc in a `cl-defstruct', so that the dispatching by type
+;; can be nominal instead of duck-typing.  I'm not sure if this is a good idea
+;; or not.  If I do this, I should provide isomorphisms to map between idiomatic
+;; ways of working with Elisp data structures and my wrapped variants.
+
+;; TODO: Are function aliases/synonyms even a good idea?  Or do they just
+;; bloat the API unnecessarily?

+;;; maybe.el --- Library for dealing with nil values -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>

+;;; Commentary:
+;; Inspired by Elm's Maybe library.
+;;
+;; For now, a Nothing value will be defined exclusively as a nil value.  I'm
+;; uninterested in supported falsiness in this module even at risk of going
+;; against the LISP grain.
+;;
+;; I'm avoiding introducing a struct to handle the creation of Just and Nothing
+;; variants of Maybe.  Perhaps this is a mistake in which case this file would
+;; be more aptly named nil.el.  I may change that.  Because of this limitation,
+;; functions in Elm's Maybe library like andThen, which is the monadic bind for
+;; the Maybe type, doesn't have a home here since we cannot compose multiple
+;; Nothing or Just values without a struct or some other construct.
+;;
+;; Possible names for the variants of a Maybe.
+;; None    | Some
+;; Nothing | Something
+;; None    | Just
+;; Nil     | Set
+;;
+;; NOTE: In Elisp, values like '() (i.e. the empty list) are aliases for nil.
+;; What else in Elisp is an alias in this way?

+;;; me-seconds.el --- How valuable is my time? -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; Inspired by Google's concept of SWE-seconds, I decided to try and compute how
+;; value my personal time is.
+;;
+;; This library should integrate with another library that handles currency
+;; conversions using locally cached data for historial values and network
+;; requests for current values.
+;;
+;; Context sensitivity:
+;; Many of the values herein are based on my values that are a function of the
+;; year, my current salary, my current company holiday policy, and my current
+;; country holiday policy.  As such, many of these constants need to be updated
+;; whenever changes occur in order for these functions to be useful.
+;;
+;; Units of time:
+;; - seconds
+;; - minutes
+;; - hours
+;; - days
+;; - weeks
+;; - months
+;; - years
+;;
+;; Wish list:
+;; - I should create a money.el struct to work with herein.  This module would
+;;   expose basic algebra for working with money structs, which would be handy.
+;; - I should create a time.el struct for working with hours in the day.  I'd
+;;   like to be able to do (+ 9:15 17:45) cleanly.
+;;
+;; Terminology:
+;; SWE hours give an order of magnitude approximation to the cost of resources
+;; in dollars per hour at 2115 hours per year.
+;; - SWE hour (SWEh)
+;; - SWE year (SWEy)
+;; - SWE nominal
+;; - SWE opportunity
+;;
+;; Other isomorphisms include:
+;; - Borg GCU
+;; - Borg RAM
+;; - Tape (library)

+;; - Spindles (low latency)

+;;; terminator.el --- Experimenting with theming Terminator -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; I think most of this module is me getting carried away with the idea of
+;; theming Terminator.  Terminator themes are defined in a themes.json file.  As
+;; far as I know, Terminator does not support specifying these themes by name on
+;; the command line, which would greatly simplify things.  Terminator does
+;; support passing a --profile flag, however, which can be used to specify the
+;; themes.  The idea, albeit quite awkward and over-engineered, was to create
+;; these profile files on the fly and pass them to terminator.  After around 45
+;; minutes of tinkering with this, the idea is starting to disenchant me.
+;;
+;; Alternative solutions include:
+;; 1. Further investigating what other options Terminator supports.
+;; 2. Using a different terminal emulator.
+;; 3. Just right clicking Terminator and changing the themes manually.

+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; Some friendly functions that hopefully will make working with trees cheaper
+;; and therefore more appealing!
+;;
+;; Tree terminology:
+;; - leaf: node with zero children.
+;; - root: node with zero parents.
+;; - depth: measures a node's distance from the root node.  This implies the
+;;   root node has a depth of zero.
+;; - height: measures the longest traversal from a node to a leaf.  This implies
+;;   that a leaf node has a height of zero.
+;; - balanced?
+;;
+;; Tree variants:
+;; - binary: the maximum number of children is two.
+;; - binary search: the maximum number of children is two and left sub-trees are
+;;   lower in value than right sub-trees.
+;; - rose: the number of children is variable.

+;; Author: William Carroll <wpcarro@gmail.com>

+;;; Commentary:
+;; It might be best to think of Elisp vectors as tuples in languages like
+;; Haskell or Erlang.
+;;
+;; Not surprisingly, this API is modelled after Elixir's Tuple API.
+;;
+;; Some Elisp trivia:
+;; - "Array": Usually means vector or string.
+;; - "Sequence": Usually means list or "array" (see above).
+;;
+;; It might be a good idea to think of Array and Sequence as typeclasses in
+;; Elisp.  This is perhaps more similar to Elixir's notion of the Enum protocol.
+;;
+;; Intentionally not supporting a to-list function, because tuples can contain
+;; heterogenous types whereas lists should contain homogenous types.

+;;; terminal.el --- My cobbled together terminal -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; My attempts at creating a sane Emacs terminal.  Most of this work was created
+;; before I discovered and fully adopted EXWM.  Prior to this, the appeal of
+;; having terminals inside of Emacs was appealing.  So appealing in fact that I
+;; was willing to work with inferior alternatives to non-Emacs terminals
+;; (e.g. `ansi-term') instead of GUI alternatives like `alacritty` because the
+;; productivity gains of having a terminal inside of Emacs might outweigh the
+;; shortcomings of that particular terminal.
+;;
+;; All of this changed, however, after discovering EXWM, since I can embed X11
+;; GUI windows inside of Emacs.  Therefore, most of this module is maintained
+;; for historical purposes.
+;;
+;; Benefits of `ansi-term':
+;; - Color scheme remains consistent between Emacs and terminal.
+;; - Same applies to my fonts.
+;;
+;; Downsides of `ansi-term':
+;; - Paging feels sluggish with programs like `cat` and `less`.
+;; - KBDs don't provide 100% coverage of what I expect from a terminal since
+;;   they were created to cooperate with Emacs.

+;; It's quite possible that our tastes will differ here.
+;;
+;; All of these keybindings are intended to shave off milliseconds off your
