HOW I USE EMACS/DIRED AS MY FILE MANAGER
__________________________________________

Make the default view more usable
=================================

1. Don't show hidden files by default and group directories first (you
can change the switches on the fly by pressing "C-u s").

2. Move files to the trash bin instead of deleting them right away.

3. Use only one buffer when navigating the file tree.

,----
| (setq dired-listing-switches "-Bhl --group-directories-first")
| delete-by-moving-to-trash t
| dired-kill-when-opening-new-dired-buffer t)
`----

Open files with an external program
===================================

Elisp-function to open a file with the appropriate program (linux)[1].

,----
| (defun my/xdg-open ()
| "Open file on point with xdg-open."
| (interactive)
| (let ((process-connection-type nil))
| (start-process "" nil "xdg-open"
| (car (dired-get-marked-files)))))
`----

Call the function by pressing "e" but only in dired-mode. Also
truncate lines longer than the window width.

,----
| (add-hook 'dired-mode-hook
| (lambda ()
| (define-key dired-mode-map (kbd "e") #'my/xdg-open)
| (toggle-truncate-lines 1)))
`----

Shortcut to the home directory
==============================

Just a keybinding to quickly open the home directory.

,----
| (defun my/go-home ()
| "open dired buffer at home directory"
| (interactive)
| (dired "~/")
| (revert-buffer))
| (global-set-key (kbd "C-c h") 'my/go-home)
`----

Pro tip: All keys prefixed with C-c ? (where ? is a single character in
the range a..z) are reserved for user defined key bindings.

Pro tip 2: You could just use bookmark. bookmark-jump is bound to
C-x r b. Could be worse ;)
