* Description :unfold:
This module provides reasonable defaults and augmentations for [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Dired.html][Dired]] (the
built-in file manager for Emacs), powered by [[doom-package:dirvish][Dirvish]].

** Maintainers
- [[doom-user:][@hlissner]]

[[doom-contrib-maintainer:][Become a maintainer?]]

** Module flags
- +dirvish ::
  Enables full [[https://github.com/alexluigit/dirvish][dirvish]] integration, providing a more modern interface for Dired
  that is reminiscent of [[https://github.com/ranger/ranger][Ranger]].

  Without this flag, Dirvish is still installed and used, but only for its minor
  augmentations to Dired.
- +icons ::
  Enables the display of fancy icons depending on file types in dired buffers,
  as well as arrows for expanded/collapsed directories.

** Packages
- [[doom-package:dirvish]]
- [[doom-package:diredfl]]

* Installation
[[id:01cffea4-3329-45e2-a892-95a384ab2338][Enable this module in your ~doom!~ block.]]

This module has no requirements *except on BSDs* like MacOS or FreeBSD, where
=GNU ls= (aka ~gls~) is required.

Optionally, install these dependencies to improve the preview experience:
- =imagemagick= for image previews
- =poppler= (or [[doom-module::tools pdf-tools]]) for pdf previews,
- =ffmpegthumbnailer= for video previews,
- =mediainfo= for audio/video metadata generation,
- =tar= and =unzip= for archive files previews.

#+begin_src bash :eval no
$ brew install coreutils fd poppler ffmpegthumbnailer mediainfo imagemagick
#+end_src

** Debian-based
#+begin_src bash :eval no

#+end_src

* Usage
** Global bindings
You can access Dired/Dirvish by opening a directory entry in commands like
~find-file (SPC f f)~. Or you can create a Dired buffer directly with these
keybindings.

| Keybind                      | Description                        |
|------------------------------+------------------------------------|
| [[kbd:][SPC f d]]                      | Find directory with dired          |
| [[kbd:][SPC o -]]                      | Jump to current directory in dired |

These commands are available but not bound to any keys.

| Command          | Description                    |
|------------------+--------------------------------|
| [[kbd:][M-x dirvish]]      | Open dired with preview        |
| [[kbd:][M-x dirvish-dwim]] | Dirvish with smart layout      |
| [[kbd:][M-x dirvish-fd]]   | Search files in dired using fd |
| [[kbd:][M-x dirvish-side]] | Open project sidebar           |

** Dired bindings
*** Basics
| Keybind  | Description                               |
|----------+-------------------------------------------|
| [[kbd:][n]]        | Move down a line                          |
| [[kbd:][p]]        | Move up a line                            |
| [[kbd:][e]] or [[kbd][RET]] | Visit the file or directory on this line  |
| [[kbd:][(]]        | Toggle visibility of detailed information |
| [[kbd:][q]]        | Exit dired buffer                         |
| [[kbd:][^]]        | Go Up a directory                         |
| [[kbd:][m]]        | Mark a file                               |
| [[kbd:][u]]        | Unmark a file                             |
| [[kbd:][D]]        | Delete a file                             |
| [[kbd:][+]]        | Create a directory                        |
| ...      | ...                                       |

This is only a very small sample of dired keybindings, just for you to get a
sense of Dired. Other basic keybindings can be found on the official [[https://www.gnu.org/software/emacs/refcards/pdf/dired-ref.pdf][Dired
reference card]]. If you have enabled ~(evil +everywhere)~, you would get a
different set of bindings ([[kbd][j/k]] for move down/up a line), consult
=evil-collection= for the actual bindings.

*** Extras
You don't have to memorize all of Dired bindings because this module provided a
lot of easy-to-read menus such as ~dirvish-mark-menu~ (powered by
=transient.el=) for you to find the suitable command in a specific context. All
of these (sub-)menus are included in ~dirvish-dispatch (?)~, the main help menu.
Some extremely useful ones are bound to a separate keys as well.

| Keybind | Description                              |

| [[kbd:][a]]       | Quick access frequently used directories |
| [[kbd:][f]]       | Get file information under the cursor    |
| [[kbd:][y]] ...   | For copying marked files or their paths  |
| [[kbd:][s]] ...   | For creating symlinks                    |
| [[kbd:][S]]       | Sort buffer with different criteria      |

* Configuration
** Quick access entries
Use the following syntax to configure the entries displayed in
~dirvish-quick-access~ command.

#+begin_src emacs-lisp
;;; add to $DOOMDIR/config.el
(after! dirvish
  (setq! dirvish-quick-access-entries
         `(("h" "~/"                          "Home")
           ("e" ,user-emacs-directory         "Emacs user directory")
           ("c" "~/Code/"                     "Code")
           ("d" "~/Downloads/"                "Downloads")
           ("m" "/mnt/"                       "Mounted drives")
           ("t" "~/.local/share/Trash/files/" "Trash"))))
