;;; 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.)

  "Eval BODY with point on each marked line.  Return a list of BODY's results.
If no marked file could be found, execute BODY on the current line.
ARG, if non-nil, specifies the files to use instead of the marked files.
 If ARG is an integer, use the next ARG files (previous -ARG, if < 0).
   In that case, point is dragged along.  This is so that commands on
   the next ARG (instead of the marked) files can be easily chained.
 If ARG is a cons with element 16, 64, or 256, corresponding to
   `C-u C-u', `C-u C-u C-u', or `C-u C-u C-u C-u', then use all files

     64 includes directories EXCEPT `.' and `..'
    256 includes ALL directories (including `.' and `..')
 If ARG is otherwise non-nil, use the current file.
If optional third arg SHOW-PROGRESS evaluates to non-nil,
 redisplay the Dired buffer after each file is processed.

No guarantee is made about the position on the marked line.  BODY must
ensure this itself, if it depends on this.

Search starts at the beginning of the buffer, thus the car of the list
corresponds to the line nearest the end of the buffer.  This is also
true for (positive and negative) integer values of ARG.

BODY should not be too long, because it is expanded four times.

If DISTINGUISH-ONE-MARKED is non-nil, then return (t FILENAME) instead
 of (FILENAME), if only one file is marked."

With a non-positive prefix arg:

  use.  Otherwise, read it (it is not necessarily a directory name).
  If in Dired now, the current buffer name is the default.
* If READ-EXTRA-FILES-P is non-nil then read any number of directory
  or file names, to make up the Dired arbitrary-files listing.  You
  can use file-name wildcards (i.e., `*' for globbing), to include the
  matching files and directories.  Use `C-g' when done entering the
  files and directories to list.

Return a list of arguments for `dired': (DIRNAME SWITCHES).  DIRNAME
here has the same form as `dired-directory'.  When a non-positive
prefix arg is used, DIRNAME is a cons of the buffer name and the list
of file names.

  "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
 * C-x m       - Access file bookmarks (not just autofiles)"

  "Create a Dired buffer that is the union of some existing Dired buffers.
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.

The names are those that are marked in the current Dired buffer, or
all files in the directory if none are marked.  Marked subdirectories
are handled recursively in the same way.

If there is some included subdirectory that has a Dired buffer with
marked files, then (unless DONT-ASKP is non-nil) this asks you whether
to use the marked files in Dired buffers, as opposed to using all of
the files in included directories.  To this y-or-n question you can
hit `l' to see the list of files that will be included (using
`diredp-list-files').  In that `l' listing you can mouseover to see
image-file previews or use `RET' or `mouse-2' to visit files.

\(Directories in `icicle-ignored-directories' are skipped, if you use
Icicles.  Otherwise, directories in `vc-directory-exclusion-list' are
skipped.)

Non-nil IGNORE-MARKS-P means ignore all Dired markings: just get all
of the files in the current directory (and all of the subdirectories,
if INCLUDE-DIRS-P is non-nil).

Non-nil PREDICATE means include only file names for which the
PREDICATE returns non-nil.  PREDICATE must accept a file name as its
only required argument.

Non-nil INCLUDE-DIRS-P means include marked subdirectory names (but
also handle those subdirs recursively, picking up their marked files
and subdirs).

Non-nil DONT-ASKP means do not ask the user whether to use marked
instead of all.  Act as if the user was asked and replied `y'.

Non-nil optional arg ONLY-MARKED-P means collect only marked files,
instead of collecting all files if none are marked.  This argument is
ignored if IGNORE-MARKS-P is non-nil.

Optional arg DETAILS is passed to `diredp-y-or-n-files-p'."

    "Mark files here and below for which PREDICATE returns non-nil.
Like `diredp-mark-sexp', but act recursively on subdirs.

A non-negative prefix arg means to unmark those files instead.

A non-positive prefix arg means to ignore subdir markings and act
instead on ALL subdirs.  That is, mark all in this directory and all
descendant directories.

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.

  "Toggle whether Dired `find-file' commands reuse directories.
This applies also to `dired-w32-browser' commands and
`diredp-up-directory'.

A prefix arg specifies directly whether or not to reuse.
 If its numeric value is non-negative then reuse; else do not reuse.

To set the behavior as a preference (default behavior), put this in
your ~/.emacs, where VALUE is 1 to reuse or -1 to not reuse:

Note: This affects only these commands:

  `dired-find-file'
  `dired-mouse-find-file'

It does not affect the corresponding `-other-window' commands.  Note
too that, by default, mouse clicks to open files or directories open
in another window: command `diredp-mouse-find-file-other-window', not

(defun dired-mark-files-regexp (regexp &optional marker-char localp)
  "Mark all file names matching REGEXP for use in later commands.
`.' 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
   filename that is matched against REGEXP."

  "Mark files for which PREDICATE returns non-nil.
With a prefix arg, unmark or unflag those files instead.

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 \\[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."
  ;; Using `sym' = "", instead of nil, for non-linked files avoids the trap of
  ;; (string-match "foo" sym) into which a user would soon fall.
