* GUI Disable the ~menu-bar-mode~, ~tool-bar-mode~ and ~scroll-bar-mode~ early on
so the disappear quickly after emacs starts up.
These things should happen early, so that Emacs will look the way I #+BEGIN_SRC emacs-lisp
want it to as quickly as is possible. (menu-bar-mode -1)
(scroll-bar-mode -1)
(tool-bar-mode -1)
#+END_SRC
** menu-bar-mode Define a macro for deferring code until after emacs has started up.
Disable =menu-bar-mode= since I haven't used the menu bar much ever, #+BEGIN_SRC emacs-lisp
even when I first started using Emacs. (defmacro eval-after-init (&rest body)
"Defer execution of BODY until after Emacs init."
`(add-hook 'emacs-startup-hook #'(lambda () ,@body)))
#+END_SRC
#+BEGIN_SRC emacs-lisp Add ~/usr/share/emacs/site-lisp~ and
(menu-bar-mode -1) ~/usr/local/emacs/share/emacs/site-lisp~ and all their sub-directories
#+END_SRC to the ~load-path~ so I can use modules from both Emacs from the
official repository *and* the self-compiled one.
** scroll-bar-mode This should be done both when compiling the elisp file and when
loading it so it doesn't complain about missing modules and such.
Since Emacs gives a pretty good indication of where in the buffer #+BEGIN_SRC emacs-lisp
I'm working I really don't need to have the scroll bar visible. (eval-and-compile
(defun oni:path-init (dir)
"Add DIR to `load-path' and all its subdirectories, unless
DIR is already in `load-path'."
(unless (or (member dir load-path) (not (file-exists-p dir)))
(let ((default-directory dir))
(add-to-list 'load-path dir t)
(normal-top-level-add-subdirs-to-load-path))))

(oni:path-init "/usr/local/emacs/share/emacs/site-lisp"))
#+END_SRC
#+BEGIN_SRC emacs-lisp Defer loading my theme until after emacs initialization. This is
(scroll-bar-mode -1) because it has been installed with ~package.el~, and the packages aren't
#+END_SRC added to the ~load-path~ until _after_ ~init.el~ has been run through.
** tool-bar-mode #+BEGIN_SRC emacs-lisp
(eval-after-init (load-theme 'yoshi t))
#+END_SRC
I've never used the tool bar much, so remove it. Add some of my project directories and other important directories
into ~load-path~ so I can easily load libraries in them. Also, if it
exists, load ~loaddefs.el~ in each directory for autoloads.
#+BEGIN_SRC emacs-lisp #+BEGIN_SRC emacs-lisp
(tool-bar-mode -1) (mapc #'(lambda (dir)

#+END_SRC
* load-path Replace the question of ~yes~ or ~no~ with just ~y~ or ~n~, I have never (yet)
accidentally typed a ~y~ or ~n~ when asked and typing ~yes~ or ~no~ is just
too much work.
Before doing anything else I should make sure that both the #+BEGIN_SRC emacs-lisp
directories ~/usr/local/emacs/share/emacs/site-lisp~ and (defalias 'yes-or-no-p 'y-or-n-p)
~/usr/share/emacs/site-list~ are included in =load-path=, along with #+END_SRC
their subdirectories, but only if they haven't already been added
and exist. Place them at the end of =load-path= so they don't mess up
package precedence.
#+BEGIN_SRC emacs-lisp Replace these functions with better alternatives. They offer the same
(eval-and-compile functionality, plus more.

#+END_SRC
Load my preferred theme after emacs has finished starting up. Use #+BEGIN_SRC emacs-lisp
the ~emacs-startup-hook~ to wait until we're sure all ELPA packages (defalias 'list-buffers 'ibuffer)
have been loaded. (defalias 'dabbrev-expand 'hippie-expand)

Add any other interesting paths to =load-path= and, if it exists,
load the ~loaddefs.el~ file from these directories.

#+END_SRC
* y-or-n-p
Don't ask ~yes~ or ~no~, ask ~y~ or ~n~, I've never had an accidental ~y~ so
far.
#+BEGIN_SRC emacs-lisp
(defalias 'yes-or-no-p 'y-or-n-p)
#+END_SRC
* ibuffer
Use =ibuffer= instead of the default =list-buffers= because it has many
more features.
#+BEGIN_SRC emacs-lisp
(defalias 'list-buffers 'ibuffer)
#+END_SRC
* hippie-expand
Do the same with =hippie-expand= and =dabbrev-expand=.
#+BEGIN_SRC emacs-lisp
(defalias 'dabbrev-expand 'hippie-expand)
#+END_SRC
* eldoc
Don't show it when ~eldoc~ is running, I almost assume that it is
whenever I'm working in a mode that supports it anyway. This should
only execute once ~eldoc~ has been loaded.
#+BEGIN_SRC emacs-lisp
(eval-after-load "eldoc" '(diminish 'eldoc-mode))
#+END_SRC
* emms
Use the standard EMMS configuration and add some MPD settings.

Add some keybindings for EMMS.
