+#+TITLE: Visual configuration 😎
+
+Let's customize some graphical element, like dashboard, mode-line, and stuff
+
+* Dashboard							  :CANCELLED:
+
+The default Emacs splash-screen is not that useful. A useful
+splash-screen would display some recent files opened, bookmaks,
+projects and org-agenda items. Luckily, there is already a project
+that does that, [[https://github.com/rakanalh/emacs-dashboard][emacs-dashboard]].
+
+#+BEGIN_SRC emacs-lisp :tangle yes
+  (use-package dashboard
+    :ensure t
+    :config
+    (setq dashboard-banner-logo-title "Welcome to Emacs, Vincent !"
+          dashboard-startup-banner (expand-file-name "images/okumura_rin_4_by_naruto_lover16-d4ktg50.png" user-emacs-directory))
+    (dashboard-setup-startup-hook))
+#+END_SRC
+
+* Theme
+
+#+BEGIN_SRC emacs-lisp :tangle yes
+  (use-package doom-themes
+    :ensure t
+    :config
+    (setq doom-themes-enable-bolt t)
+    (setq doom-themes-enable-italic t)
+    (load-theme 'doom-one t))
+#+END_SRC
+
+A good companion to =doom-one= theme is [[https://github.com/hlissner/emacs-solaire-mode][solaire-mode]]. It helps
+visually distinguish file-visiting from other types of windows (like
+popups or sidebars).
+
+#+BEGIN_SRC emacs-lisp :tangle yes

+    :ensure t

+    (advice-add #'persp-load-state-from-file :after #'solaire-mode-restore-persp-mode-buffers))
+#+END_SRC
+* Lines and columns
+
+We want to see somewhere the column and line number, and also
+highlight the current line to see it easily.

+
+* Syntax highlighting
+
+Depending on the files opened and the syntax highlighting enabled,
+~font-lock-mode~ can be slow, we try to limit that, to keep Emacs
+reactive.
+
+#+BEGIN_SRC emacs-lisp :tangle yes
+  (setq font-lock-maximum-decoration 2)
+#+END_SRC
+
+* Fringe decorations
+
+[[http://www.emacswiki.org/emacs/TheFringe][The fringe]] is the vertical region at the right and left of the
+buffer. Emacs lets you customize it of course.
+
+#+BEGIN_SRC emacs-lisp :tangle yes
+  (setq-default indicate-buffer-boundaries 'left)
+  (setq-default indicate-empty-lines +1)
+#+END_SRC
+
+* Byte-compiles =.emacs.d= folder
+
+Let's also define a quick function to byte-compile files under
+=.emacs.d= folder to speed things up.
+
+#+BEGIN_SRC emacs-lisp :tangle yes
+  (defun vde/byte-recompile ()

+    (byte-recompile-directory (expand-file-name "lisp/use-package" user-emacs-directory) 0))
+#+END_SRC
+
+* Fonts
+
+Depending on the machine used I might not have the correct font
+installed or another one renders better. I am a long-time fan of
+=Ubuntu Mono= fonts but some fonts are starting to interesting me,
+mainly =[[https://github.com/tonsky/FiraCode][Fira]]= and =[[https://github.com/i-tu/Hasklig][Hasklig]]= which do symbol ligatures.
+

+    (cond ((x-list-fonts "Ubuntu Mono") "Ubuntu Mono-14")
+          ((x-list-fonts "Hasklig") "Hasklig-14")

+#+END_SRC
+
+Let's write some emojis to see how they look 🙆 😆 😁 ♨ ⛅ 🚲.
+
+* Line numbers
+
+Enable line-number and column number mode (in the mode line) but also
+add linum on programming modes (feel safe to enable on those but not
+on other file that could be too big).

+
+;;; Commentary:
+
+;; Minor modes each put a word on the mode line to signify that they're
+;; active.  This can cause other displays, such as % of file that point is
+;; at, to run off the right side of the screen.  For some minor modes, such
+;; as mouse-avoidance-mode, the display is a waste of space, since users
+;; typically set the mode in their .emacs & never change it.  For other
+;; modes, such as my jiggle-mode, it's a waste because there's already a
+;; visual indication of whether the mode is in effect.
+
+;; A diminished mode is a minor mode that has had its mode line
+;; display diminished, usually to nothing, although diminishing to a
+;; shorter word or a single letter is also supported.  This package
+;; implements diminished modes.
+
+;; You can use this package either interactively or from your .emacs file.
+;; In either case, first you'll need to copy this file to a directory that
+;; appears in your load-path.  `load-path' is the name of a variable that
+;; contains a list of directories Emacs searches for files to load.
+;; To prepend another directory to load-path, put a line like
+;; (add-to-list 'load-path "c:/My_Directory") in your .emacs file.
+
+;; To create diminished modes interactively, type
+;;   M-x load-library
+;; to get a prompt like
+;;   Load library:
+;; and respond `diminish' (unquoted).  Then type
+;;   M-x diminish
+;; to get a prompt like
+;;   Diminish what minor mode:
+;; and respond with the name of some minor mode, like mouse-avoidance-mode.
+;; You'll then get this prompt:
+;;   To what mode-line display:
+;; Respond by just hitting <Enter> if you want the name of the mode
+;; completely removed from the mode line.  If you prefer, you can abbreviate
+;; the name.  If your abbreviation is 2 characters or more, such as "Av",
+;; it'll be displayed as a separate word on the mode line, just like minor
+;; modes' names.  If it's a single character, such as "V", it'll be scrunched
+;; up against the previous word, so for example if the undiminished mode line
+;; display had been "Abbrev Fill Avoid", it would become "Abbrev FillV".
+;; Multiple single-letter diminished modes will all be scrunched together.
+;; The display of undiminished modes will not be affected.
+
+;; To find out what the mode line would look like if all diminished modes
+;; were still minor, type M-x diminished-modes.  This displays in the echo
+;; area the complete list of minor or diminished modes now active, but
+;; displays them all as minor.  They remain diminished on the mode line.
+
+;; To convert a diminished mode back to a minor mode, type M-x diminish-undo
+;; to get a prompt like
+;;   Restore what diminished mode:
+;; Respond with the name of some diminished mode.  To convert all
+;; diminished modes back to minor modes, respond to that prompt
+;; with `diminished-modes' (unquoted, & note the hyphen).
+
+;; When you're responding to the prompts for mode names, you can use
+;; completion to avoid extra typing; for example, m o u SPC SPC SPC
+;; is usually enough to specify mouse-avoidance-mode.  Mode names
+;; typically end in "-mode", but for historical reasons
+;; auto-fill-mode is named by "auto-fill-function".
+
+;; To create diminished modes noninteractively in your .emacs file, put
+;; code like
+;;   (require 'diminish)
+;;   (diminish 'abbrev-mode "Abv")
+;;   (diminish 'jiggle-mode)
+;;   (diminish 'mouse-avoidance-mode "M")
+;; near the end of your .emacs file.  It should be near the end so that any
+;; minor modes your .emacs loads will already have been loaded by the time
+;; they're to be converted to diminished modes.
+
+;; To diminish a major mode, (setq mode-name "whatever") in the mode hook.

+;; appetite for the wisdom of the self-critical among the creatures of
+;; material appetite who dominate our world.  Their dominance's Darwinian
+;; implications reinforce the self-doubt that is the germ of higher wisdom.
+;; The thoughtful contemplate the evolutionary triumph of the predator.
+;; Gnostics deny the cosmos could be so evil; this must all be a prank; the

+;; Loons come to Seattle all the time, but the ones that like it learn to be

+
+;;; Commentary:
+
+;; On OS X (and perhaps elsewhere) the $PATH environment variable and
+;; `exec-path' used by a windowed Emacs instance will usually be the
+;; system-wide default path, rather than that seen in a terminal
+;; window.
+
+;; This library allows the user to set Emacs' `exec-path' and $PATH
+;; from the shell path, so that `shell-command', `compile' and the
+;; like work as expected.
+
+;; It also allows other environment variables to be retrieved from the
+;; shell, so that Emacs will see the same values you get in a terminal.
+
+;; If you use a non-POSIX-standard shell like "tcsh" or "fish", your
+;; shell will be asked to execute "sh" as a subshell in order to print
+;; out the variables in a format which can be reliably parsed.  "sh"
+;; must be a POSIX-compliant shell in this case.
+
+;; Note that shell variables which have not been exported as
+;; environment variables (e.g. using the "export" keyword) may not be
+;; visible to `exec-path-from-shell'.
+
+;; Installation:
+
+;; ELPA packages are available on Marmalade and MELPA.  Alternatively,
+;; place this file on a directory in your `load-path', and explicitly
+;; require it.
+
+;; Usage:
+;;
+;;     (require 'exec-path-from-shell) ;; if not using the ELPA package
+;;     (exec-path-from-shell-initialize)
+;;
+;; Customize `exec-path-from-shell-variables' to modify the list of
+;; variables imported.
+;;
+;; If you use your Emacs config on other platforms, you can instead
+;; make initialization conditional as follows:
+;;
+;;     (when (memq window-system '(mac ns))
+;;       (exec-path-from-shell-initialize))
+;;
+;; Alternatively, you can use `exec-path-from-shell-copy-envs' or
+;; `exec-path-from-shell-copy-env' directly, e.g.
+;;
+;;     (exec-path-from-shell-copy-env "PYTHONPATH")
