* Emacs configuration

** Configure ~use-package~

#+BEGIN_SRC emacs-lisp
  (unless (package-installed-p 'use-package)
    (package-refresh-contents)
    (package-install 'use-package))

  (setq use-package-always-ensure t
        use-package-verbose t)

  (require 'use-package)
#+END_SRC

** Set up my personal keymap

I set it up early so I can use it in ~use-package~ calls immediately.

#+BEGIN_SRC emacs-lisp
(defvar gpolonkai/pers-map (make-sparse-keymap)
  "My own, personal, keymap!")
(define-prefix-command 'gpolonkai/pers-map)
(define-key ctl-x-map "t" 'gpolonkai/pers-map)
#+END_SRC

** I really don’t want to type more than I really must…

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

** Who am I?   Where am I?

#+BEGIN_SRC emacs-lisp
(setq user-full-name "Gergely Polonkai"
      user-mail-address "gergely@polonkai.eu"
      calendar-latitude 47.4
      calendar-longitude 19.0
      calendar-location-name "Budapest, Hungary")
#+END_SRC

* Add ~lisp/~ to ~load-path~

#+BEGIN_SRC emacs-lisp
(add-to-list 'load-path (expand-file-name
                         (convert-standard-filename "lisp/")
                         user-emacs-directory))
#+END_SRC

* UI preferences

** Tweak window chrome

Turn off the scroll bar (that’s why Nyan-cat is here), the toolbar (I don’t really use it), and
the menu bar (I rarely use it, and in those rare occasions I can simply turn it on.)

Also, maximise the frame.

#+BEGIN_SRC emacs-lisp
(tool-bar-mode 0)
(menu-bar-mode 0)
(when window-system
  (scroll-bar-mode -1))

(set-frame-parameter nil 'fullscreen 'maximized)
#+END_SRC

** Set the default font and configure font resizing

#+BEGIN_SRC emacs-lisp
(set-face-attribute 'default t :font "Hack-10")
(set-frame-font "Hack-10" nil t)
#+END_SRC

* Set up global minor modes provided by Emacs

** Pretty lambdas

Because we can.

#+BEGIN_SRC emacs-lisp
(global-prettify-symbols-mode t)
#+END_SRC

* ~use-package~ packages

** Highlight the current line

#+BEGIN_SRC emacs-lisp
(use-package hl-line
  :config
  (when window-system
    (global-hl-line-mode)))
#+END_SRC

** Hide certain modes from the mode line

#+BEGIN_SRC emacs-lisp
(use-package diminish
  :defer t)
#+END_SRC
