#+TITLE: Emacs Config

* General Settings

Typing =:ensure t= everywhere is very bothersome so I'd rather *not* do that.

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

Don't create all the custom things.

#+BEGIN_SRC emacs-lisp
  (defconst custom-file "/dev/null")
#+END_SRC

I don't want my Emacs to create loads of backup files, swap files, etc.

#+BEGIN_SRC emacs-lisp
  (setq make-backup-files nil)
  (setq auto-save-default nil)
#+END_SRC

Nor do I need all the (Windows 2000-esque) UI.

#+BEGIN_SRC emacs-lisp
  (scroll-bar-mode -1)
  (tool-bar-mode -1)
  (tooltip-mode -1)
  (menu-bar-mode -1)
#+END_SRC

When I fire up Emacs I want to be greeted with an empty =*scratch*= buffer, not the weird GNU screen.

#+BEGIN_SRC emacs-lisp
  (setq inhibit-splash-screen t
        initial-scratch-message "")
#+END_SRC

The whole yes or no prompt takes too much time to type out. y and n is much better.

#+BEGIN_SRC emacs-lisp
  (defalias 'yes-or-no-p 'y-or-n-p)
#+END_SRC

UTF-8 is good and should be the default for everything.

#+BEGIN_SRC emacs-lisp
  (setq locale-coding-system 'utf-8)
  (set-terminal-coding-system 'utf-8)
  (set-keyboard-coding-system 'utf-8)
  (set-selection-coding-system 'utf-8)
  (prefer-coding-system 'utf-8)
#+END_SRC

Which key makes Emacs self documenting.

#+BEGIN_SRC emacs-lisp
  (use-package which-key
    :config
	(setq which-key-idle-delay 0.25)
    (which-key-mode 1))
#+END_SRC


** Restart emacs
   
Restarting emacs from within emacs!

#+BEGIN_SRC emacs-lisp
(use-package restart-emacs
	:config
	(setq restart-emacs-restore-frames t))
#+END_SRC

** disable clipboard whatever


Clipboard shit is fucked, so this is necessary to unfuck.

#+BEGIN_SRC emacs-lisp
	(setq x-select-enable-clipboard-manager nil)
#+END_SRC

** Store recent files

#+BEGIN_SRC emacs-lisp
(recentf-mode 1)
(setq recentf-max-menu-items 25)
(setq recentf-max-saved-items 25)
;; (run-at-time nil (* 5 60) 'recentf-save-list)
#+END_SRC
