* Setup load-path                                          :load_path:

  Not everything can be installed with ~package.el~. Or some things can,
  but I prefer installing them manually because it's easier. Anyway,
  some additions should be made to =load-path= and if the file
  ~loaddefs.el~ exists, load it for the autoloads.

  #+BEGIN_SRC emacs-lisp
    (mapc #'(lambda (dir)
              (add-to-list 'load-path dir)
              (let ((loaddefs (concat dir "/loaddefs.el")))
                (when (file-exists-p loaddefs)
                  (load loaddefs))))
          '("~/.emacs.d/site-lisp" "~/projects/emacs/pony-mode/src"
            "~/projects/emacs/php-mode" "~/.emacs.d/vendor-lisp/org/lisp"
            "~/.emacs.d/vendor-lisp/org/contrib/lisp"))
  #+END_SRC

* Load other functions

  Including all the functions being used here would make this file
  immens and perhaps also somewhat unclear. In any case there are a
  number of functions that I have found on the web in ~ext.el~, and a
  number that I have written myself in ~oni.el~. So load them.

  #+BEGIN_SRC emacs-lisp
    (require 'ext)
    (require 'oni)
  #+END_SRC

* Load theme                                                   :theme:

  I have been experimenting with my own color theme for quite a while
  now. I use ~package.el~ to install it, so to load it I need to wait
  until after it has been loaded to enable it. Some of these settings
  have also been specified in my [[file:../.Xdefaults][Xdefaults]] so that it doesn't start
  with a completely white background (for too long).

  #+BEGIN_SRC emacs-lisp
    (oni:eval-after-init (load-theme 'yoshi t))
  #+END_SRC

* Replace yes or no with y or n                             :y_or_n_p:

  I have never had the trouble of accidentally pressing ~y~ at the
  moment Emacs wants to ask me something. And having to type ~yes <RET>~
  for a simple question gets in the way of things, so I prefer
  =y-or-n-p=.

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

* Replace list-buffers with ibuffer                          :ibuffer:

  ~ibuffer~ offers some excellent ways to manage buffers. One of which
  is the function to filter the buffer list on (almost) any predicate,
  including the buffer's mode. ~list-buffers~ is simplistic compared to
  this.

  #+BEGIN_SRC emacs-lisp
    (defalias 'list-buffers 'ibuffer)
  #+END_SRC

* Replace dabbrev with hippie-expand                   :hippie_expand:

  =hippie-expand= has an expansion that functions the same as
  =dabbrev-expand= and it also has many more. I cannot think of a reason
  why =dabbrev-expand= should be used when =hippie-expand= is also an
  option.

  #+BEGIN_SRC emacs-lisp
    (defalias 'dabbrev-expand 'hippie-expand)
  #+END_SRC

* Hide compilation window after success                  :compilation:

  If compilation was succesfull I really don't need to see the
  compilation window. So if either ~*Compilation*~ or ~*compilation*~
  finishes correctly, delete the windows and show a message instead.

  #+BEGIN_SRC emacs-lisp
    (defun ext:comp-finish-function (buf str)
      "Close the compilation buffer quickly if everything went OK."
      (if (string-match "exited abnormally" str)
          ;; there were errors
          (message "compilation errors, press C-x ` to visit")
        ;; no errors, make the compilation window go away in 0.5 seconds
        (when (member (buffer-name) '("*Compilation*" "*compilation*"))
          (delete-windows-on buf)
          (message "No compilation errors!"))))

    (add-to-list 'compilation-finish-functions 'ext:comp-finish-function)
  #+END_SRC

* Enable auto-fill-mode                                    :auto_fill:

  =auto-fill-mode= automatically inserts newlines when a line becomes
  too long. This is useful for both text modes and the comments in
  programming modes. What it takes for a line to become too long is
  specified by the =fill-column= variable.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'prog-mode-hook 'auto-fill-mode)
    (add-hook 'text-mode-hook 'auto-fill-mode)
  #+END_SRC

* Enable eldoc-mode                                            :eldoc:

  =eldoc-mode= shows the arguments for the function call at point in the
  minibuffer, or in the mode-line if you're in the minibuffer. This is
  very useful when writing Emacs Lisp code.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'emacs-lisp-mode-hook 'eldoc-mode)
    (add-hook 'ielm-mode-hook 'eldoc-mode)
  #+END_SRC

* Enable fill-column-indicator                 :fill_column_indicator:

  Emacs has many packages that try to deal with showing a right
  margin, the 80th column which your code should not go beyond. None
  of these packages get it quite right, but =fill-column-indicator= gets
  pretty close.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'html-mode-hook 'fci-mode)
    (add-hook 'prog-mode-hook 'fci-mode)
  #+END_SRC

* Enable flycheck-mode                                      :flycheck:

  Flycheck is a modern version of Flymake. They're not actually
  related, but Flycheck did come from the idea of Flymake. Flycheck
  has some interesting graphical elements (uses the fringe) and seems
  to have a pretty flexible way of creating new checkers. I enable it
  for all the modes that I use it supports.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'css-mode-hook        'flycheck-mode)
    (add-hook 'emacs-lisp-mode-hook 'flycheck-mode)
    (add-hook 'go-mode-hook         'flycheck-mode)
    (add-hook 'html-mode-hook       'flycheck-mode)
    (add-hook 'js2-mode-hook        'flycheck-mode)
    (add-hook 'lua-mode-hook        'flycheck-mode)
    (add-hook 'php-mode-hook        'flycheck-mode)

    (add-hook 'rst-mode-hook        'flycheck-mode)
    (add-hook 'ruby-mode-hook       'flycheck-mode)
    (add-hook 'rust-mode-hook       'flycheck-mode)
    (add-hook 'sh-mode-hook         'flycheck-mode)
  #+END_SRC

* Enable flyspell-mode                                      :flyspell:

  What Flymake and Flycheck are to compilation, Flyspell is to
  spelling. Runs spell checking in the background and highlights
  spelling errors. It might be useful in programming mode comments,
  but that seems a bit over the top for me, I care about the code, not
  so much about the words used. So I only enable it in =text-mode=.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'text-mode-hook 'flyspell-mode)
  #+END_SRC

* Enable paredit-mode                                        :paredit:

  I had long thought of =paredit-mode= as overly complex and not very
  useful. Though maybe I did try it out last before I started writing
  so much Lisp code. In any case, I was wrong, it is one of the best
  modes to use when editing Lisp and Lisp-like languages, changes your
  whole perspective on the code.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'clojure-mode-hook    'paredit-mode)
    (add-hook 'emacs-lisp-mode-hook 'paredit-mode)
    (add-hook 'lisp-mode-hook       'paredit-mode)
    (add-hook 'sawfish-mode-hook    'paredit-mode)
    (add-hook 'scheme-mode-hook     'paredit-mode)
    (add-hook 'ielm-mode-hook       'paredit-mode)
  #+END_SRC

* Enable rainbow-delimiters-mode                  :rainbow_delimiters:

  Any language can have quite deeply nested "delimeters", meaning
  parentheses, brackets, curly braces. It helps to see their depth
  visually. Not just in Lisp.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'prog-mode-hook 'rainbow-delimiters-mode)
  #+END_SRC

* Enable rainbow-mode                                        :rainbow:

  When editing color-heavy "code", like CSS, it's useful to be able to
  see color you're specifying. =rainbow-mode= does this.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'css-mode-hook 'rainbow-mode)
  #+END_SRC

* Enable slime-js-minor-mode                                     :js2:

  SLIME is one of the coolest things about using Emacs to edit Lisp
  code, so if there is something similar for JavaScript, even makes it
  worth it to use the seemingly over-engineered =js2-mode=.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'js2-mode-hook 'slime-js-minor-mode)
  #+END_SRC

* Enable smartparens-mode                                :smartparens:

  =smartparens-mode= is a less strict and less lisp-focused mode that
  tries to do something similar to =paredit-mode=. It is nice to use if
  you're not writing in a Lisp-like language.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'html-mode-hook   'smartparens-mode)
    (add-hook 'python-mode-hook 'smartparens-mode)
  #+END_SRC

* Enable visual-line-mode                                :visual_line:

  Having words run off the screen in a chat session is unpleasant.
  Having the words cut-off wherever the line ends is even worse! Use
  =visual-line-mode= to get some proper word wrapping behaviour in these
  buffers.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'jabber-chat-mode-hook 'visual-line-mode)
    (add-hook 'erc-mode-hook         'visual-line-mode)
  #+END_SRC

* Enable whitespace-mode                                  :whitespace:

  In most programming languages whitespace is pretty unimportant. As
  long as the readers can stand it the compilers/interpreters usually
  don't care. Of course this is not true for Python, and Markdown also
  has special meanings for some whitespace in some places, so enabling
  =whitespace-mode= is a good idea, just for these two situations.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'markdown-mode-hook 'whitespace-mode)
    (add-hook 'python-mode-hook   'whitespace-mode)
  #+END_SRC

* Enable yas-minor-mode                                          :yas:

  I still need to figure out where this mode comes in in my workflow.
  I try to limit code-repetition as much as I can and anything that
  does repeat often is so trivial that it doesn't benefit from
  snippets. And using snippets for =if= statements and such doesn't
  strike me as terribly useful either. But perhaps I haven't seen the
  magic of it yet. I do know that it is an interesting tool and I wish
  to find a use for it at some point.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'html-mode-hook 'yas-minor-mode)
    (add-hook 'org-mode-hook  'yas-minor-mode)
    (add-hook 'prog-mode-hook 'yas-minor-mode)
  #+END_SRC

* Enable tagedit-mode                                        :tagedit:

  =tagedit-mode= tries to be for XML/HTML what =paredit-mode= is for Lisp.
  And because of this, it *rocks*. It almost makes me feel sorry that I
  don't write all that much XML or HTML nowadays. Enable the
  experimental features as well, so it's really close to =paredit-mode=.

  #+BEGIN_SRC emacs-lisp
    (defun oni:turn-on-tagedit-mode ()
      (require 'tagedit)
      (tagedit-mode)
      (tagedit-add-paredit-like-keybindings)
      (tagedit-add-experimental-features))

    (add-hook 'html-mode-hook 'oni:turn-on-tagedit-mode)
  #+END_SRC

* Make ^L look pretty                                           :ppcL:

  This mode should be activated each time a frame is made, since it
  uses certain frame properties.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'emacs-startup-hook 'pretty-control-l-mode)
    (add-hook 'after-make-frame-functions
              '(lambda (arg) (pretty-control-l-mode)))
  #+END_SRC

* Customize eshell prompt                                     :eshell:

  Create a prompt that shows the following:

  - The exit code of the previous command: a green ~+~ for exit code ~0~
    and a red ~-~ for any non-zero exit code.

  - The hostname of the device running the current Emacs instance.

  - An abbreviated indication of the current directory. To keep things
    short this abbreviation is the first letter of each parent
    directory and the full name of the current directory, still
    separated by ~/~, though.

  - Which branch (if any) the current directory has been checked-out
    of. This is not shown if the current directory is not a git
    directory.

  #+BEGIN_SRC emacs-lisp
    (defun oni:eshell-prompt-function ()
      "Show a pretty shell prompt."
      (let ((status (if (zerop eshell-last-command-status) ?+ ?-))
            (hostname (oni:hostname))
            (dir (abbreviate-file-name (eshell/pwd)))
            (branch
             (shell-command-to-string
              "git branch --contains HEAD 2>/dev/null | sed -e '/^[^*]/d'")))
        (concat
         (propertize (char-to-string status)
                     'face `(:foreground ,(if (= status ?+)
                                              "green"
                                            "red")))
         " "
         (propertize hostname 'face 'mode-line-buffer-id)
         " "
         (propertize (oni:shorten-dir dir) 'face 'font-lock-string-face)
         " "
         (when (not (string= branch ""))
           (propertize
            ;; Cut off "* " and "\n"
            (substring branch 2 -1)
            'face 'font-lock-function-name-face))
         " \n> ")))
  #+END_SRC

* Add a pop-up function for eshell                            :eshell:

  When working I often need to switch to a shell to issue some quick
  commands and then be on my merry way again, to help with this I have
  added a function which tries to move the current working directory
  to that of the file being worked on and shows eshell. I bind this
  function to ~f8~ for easy access.

  #+BEGIN_SRC emacs-lisp
    (defun oni:raise-eshell ()
      "Start or switch back to `eshell'.
    Also change directories to current working directory."
      (interactive)
      (let ((dir (file-name-directory
                  (or (buffer-file-name) "~/")))
            (hasfile (not (eq (buffer-file-name) nil)))
            (started (and (boundp 'eshell-buffer-name) eshell-buffer-name
                          (buffer-live-p (get-buffer eshell-buffer-name)))))
        (eshell)
        (when (and hasfile (eq eshell-process-list nil))
          (eshell/cd dir)
          (when started
            (eshell-reset)))))

    (global-set-key (kbd "<f8>") 'oni:raise-eshell)
  #+END_SRC

* Disable undo in eshell buffers                              :eshell:

  Eshell buffers can get big and undo does not serve any real purpose
  in these buffers. Instead of getting boundary limit popups all the
  time, which I do want to keep for other buffers, it's easier to
  just turn off undo information for such buffers.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'eshell-mode-hook 'buffer-disable-undo)
  #+END_SRC

* Enable some "advanced" functions

  These functions are disabled by default, because beginners find them
  confusing, apparently. Though I won't say I'm an Emacs master or
  guru, I *can* say that I'm not a beginner, and these functions have
  not confused me yet. So enable them.

  #+BEGIN_SRC emacs-lisp
    (put 'downcase-region  'disabled nil)
    (put 'narrow-to-page   'disabled nil)
    (put 'narrow-to-region 'disabled nil)

    (put 'upcase-region    'disabled nil)
  #+END_SRC

* Don't echo status changes for jabber                        :jabber:

  If I'm talking to someone I'll see their status and if they're
  offline and I want to say something I can say it anyway, I don't
  need constant updates in my echo-area on the status of my jabber
  buddies. But since this relies on something from the ~jabber~ module,
  only run it after that module has been loaded.

  #+BEGIN_SRC emacs-lisp
    (eval-after-load "jabber"
      '(remove-hook 'jabber-alert-presence-hooks 'jabber-presence-echo))
  #+END_SRC

* Use libnotify for jabber notifications                      :jabber:

  The functions don't seem to be loaded automatically, so add
  autoloads for the libnotify functions.

  #+BEGIN_SRC emacs-lisp
    (autoload 'jabber-message-libnotify "jabber-libnotify")
    (autoload 'jabber-muc-libnotify     "jabber-libnotify")

    (add-hook 'jabber-alert-message-hooks 'jabber-message-libnotify)
    (add-hook 'jabber-alert-muc-hooks     'jabber-muc-libnotify)
  #+END_SRC

* Enable idomenu                                             :idomenu:

  Imenu is an awesome feature, but since I don't use any menus it is
  a little lost on me. =idomenu= uses Imenu, but shows it in an
  ido-like way, which works perfectly. Bind it to ~M-n~.

  #+BEGIN_SRC emacs-lisp
    (global-set-key (kbd "M-n") 'idomenu)
  #+END_SRC

* Enable jedi                                                   :jedi:

  jedi is an interesting auto-completion program for the Python
  programming language. On archlinux the program you usually want to
  use is ~python2~, so change the =jedi:server-command= accordingly and
  run =jedi:setup= when =python-mode= starts to enable it.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'python-mode-hook 'jedi:setup)
  #+END_SRC

* Org initialization                                             :org:

  Since my intialization for =org-mode= got so big, I moved it to a
  separate file. This file should be loaded after the =org= module
  loads.

  #+BEGIN_SRC emacs-lisp
    (eval-after-load "org" '(require 'org-init))
  #+END_SRC

* Indent-defun

  The emacsredux website had an interesting [[http://emacsredux.com/blog/2013/03/28/indent-defun/][tip]].

  #+BEGIN_SRC emacs-lisp

  #+END_SRC

* Close term buffer after exit                                  :term:

  When quitting the process in a term buffer, in other words, when
  quitting the shell, kill the buffer. Killing the shell, but not
  killing the buffer is a pain, it keeps you from quickly starting a
  term and quickly closing it too. This advice should be disabled if
  ever the shell crashes, because it doesn't look at the exit code,
  since the standard exit code is that of the last run command.

  #+BEGIN_SRC emacs-lisp
    (defadvice term-handle-exit (after oni:kill-buffer-after-exit activate)
      "Kill the term buffer if the process finished."
      (kill-buffer (current-buffer)))
  #+END_SRC

* Changing case

  I have no capslock key, and holding shift whilst typing big words
  is annoying, so I wrote a couple of functions to help with that and
  bind them to ~C-c u~ and ~C-c d~.

  #+BEGIN_SRC emacs-lisp
    (global-set-key (kbd "C-c u") 'oni:upcase-prev)
    (global-set-key (kbd "C-c d") 'oni:downcase-prev)
  #+END_SRC

* Turn off usage of tabs for vala-mode                          :vala:

  Somehow =vala-mode= thinks it's ok for it to decide that it's users
  should always use tabs. As far as I'm aware the vala compiler has
  no such restriction, so turn it off.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'vala-mode-hook 'oni:vala-mode-func)
  #+END_SRC

* Use smex                                                      :smex:

  Smex is to command selection what ido is to file selection. Very
  similar too, it was written with ido specifically in mind.

  #+BEGIN_SRC emacs-lisp
    (global-set-key (kbd "M-x")   'smex)

  #+END_SRC

* Autoload define-slime-contrib                                  :js2:

  =slime-js-minor-mode= uses this function but forgets to require its
  module, so I set up an autoload function for when I need it and
  haven't yet used slime.

  #+BEGIN_SRC emacs-lisp
    (autoload 'define-slime-contrib "slime")
  #+END_SRC

* Autoload some other functions

  These need to have autoloads specified for various reasons, mostly
  because they're installed manually or because they're old.

  #+BEGIN_SRC emacs-lisp

* Uniquify buffers better                                   :uniquify:

  The default way to make sure buffer names are unique is rather
  uninformative, =uniquify= has a few better options.

  #+BEGIN_SRC emacs-lisp
    (require 'uniquify)
  #+END_SRC

* Don't warn about mumamo                                        :php:

  I haven't yet seen a mode that offers good multiple major modes
  support. And so I don't use any, so don't warn me that I don't.

  #+BEGIN_SRC emacs-lisp
    (setq-default php-mode-warn-if-mumamo-off nil)
  #+END_SRC

* Automatically determine browser                             :browse:

  Use the =BROWSER= environment variable to figure out which browser to
  call for =browse-url=.

  #+BEGIN_SRC emacs-lisp
    (setq browse-url-generic-program  (getenv "BROWSER"))
  #+END_SRC

* Move customize settings into their own file                 :custom:

  Any settings I change using the customize interface should go into
  a separate file. My ~init.el~ is under version control and I don't
  want each local change made in this way to be recorded in the VCS.
  Plus the code generated by customize is an eyesore.

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

* Stop elnode from running automatically                      :elnode:

  I like elnode, but it really should stop starting itself up every
  time I start emacs. Not only can this cause problems with trying
  to run on the same port, but also this starts running programs that
  I have no idea of, whatever I was testing last.

  #+BEGIN_SRC emacs-lisp
    (setq elnode-do-init nil)
  #+END_SRC

* Mention the buffer in the frame title

  Having 5 Emacs frames all named "emacs" doesn't help to identify
  them, so add the opened buffer name to the title.

  #+BEGIN_SRC emacs-lisp
    (setq frame-title-format '(:eval (concat "emacs: " (buffer-name))))
  #+END_SRC

* Store geiser history under .emacs.d

  Everything Emacs related should be stored under ~HOME/.emacs.d~ so as
  not to fill my home directory with a bunch of directories.

  #+BEGIN_SRC emacs-lisp
    (setq geiser-repl-history-filename "~/.emacs.d/geiser-history")
  #+END_SRC

* Set inferior lisp program to SBCL                             :lisp:

  SBCL seems like a very good Lisp implementation to use, widely
  supported by packagers too.

  #+BEGIN_SRC emacs-lisp
    (setq inferior-lisp-program "sbcl")
  #+END_SRC

* Turn on compilation-shell-minor-mode for pony buffers         :pony:

  Turn on =compilation-shell-minor-mode= whenever =pony-minor-mode= starts
  in a =comint-mode= buffer. Since buffers like ~*ponymanage*~ and
  ~*ponyserver*~ don't have their own specialized modes, but use
  =comint-mode= and turn on =pony-minor-mode=, and I don't want to enable
  =compilation-shell-minor-mode= for *every* =comint-mode= buffer, we can
  add a hook that adds a local hook.

  I use =compilation-shell-minor-mode= because some pony mode buffers
  are interactive, such as the pony-shell buffer.

  #+BEGIN_SRC emacs-lisp
    (defun turn-on-compilation-shell-for-pony ()
      (add-hook 'pony-minor-mode-hook 'compilation-shell-minor-mode nil t))
    (add-hook 'comint-mode-hook 'turn-on-compilation-shell-for-pony)
  #+END_SRC

* Make smartparens a little stricter                     :smartparens:

  Set the delete and backspace keys to some smartparens keybindings
  that should make pair balancing a little stricter. These key
  bindings refuse to delete pair delimeters or skip over them if they
  still have content.

  #+BEGIN_SRC emacs-lisp
    (defun oni:smartparens-set-keys ()
      (local-set-key (kbd "DEL") 'sp-backward-delete-char)
      (local-set-key (kbd "<deletechar>") 'sp-delete-char)
      (local-set-key (kbd "C-d") 'sp-delete-char))

    (add-hook 'smartparens-mode-on-hook 'oni:smartparens-set-keys)
  #+END_SRC

* Initialize EMMS                                               :emms:

  Initialize a minimal EMMS setup. Load the default players so we can
  use mplayer or any of the generic mp3 and ogg players.

  Load the MPD player so we can connect to MPD and use that if
  possible, set the music directory to MPD's music directory so it
  knows how to translate filenames to something MPD understands.

  Load the =emms-mode-line= module so we can display some information in
  the mode-line about which song is playing and set my preferred
  function for extracting this information. The =emms-info-mpd= function
  doesn't seem to return anything, so I've had to improvise to turn
  absolute file names into something nicer.

  #+BEGIN_SRC emacs-lisp
    (eval-after-load "emms"
      `(progn
         (emms-minimalistic)
