* Initial setup

These commands need to be run after the first startup.

** Irony mode

M-x =irony-install-server=

** All the icons

M-x =all-the-icons-install-fonts=

* Customizations

Store custom-file separately, don't freak out when it's not found.

#+BEGIN_SRC emacs-lisp
  (setq custom-file "~/.emacs.d/custom.el")
  (load custom-file 'noerror)
#+END_SRC

Set custom faces, without using customize.

#+BEGIN_SRC emacs-lisp
  (set-face-attribute 'default nil :height 90 :family "DejaVu Sans Mono")
#+END_SRC

* Package Management
** Ensure

Ensures packages are installed by default.

#+BEGIN_SRC emacs-lisp
  (require 'use-package-ensure)
  (setq use-package-always-ensure t)
#+END_SRC

** Auto update

Update pending updates of installed packages at startup.
https://github.com/rranelli/auto-package-update.el

#+BEGIN_SRC emacs-lisp
  (use-package auto-package-update
	:custom
	(auto-package-update-delete-old-versions t)

	(auto-package-update-last-update-day-path (concat emacs-cache "/.last-package-update-day"))
	:config
	(auto-package-update-maybe))
#+END_SRC

Automatically compile all packages.
https://github.com/emacscollective/auto-compile

#+BEGIN_SRC emacs-lisp
  (use-package auto-compile
	:custom (load-prefer-newer t)
	:config
	(auto-compile-on-load-mode)
