* Turn off useless visual components                             :gui:

  Turn the menu, scroll-bar and tool-bar off quickly. If this happens
  later on then the GUI will show these components for a longer time.
  Even though these options are also specified in my [[file:../.Xdefaults][Xdefaults]] I like
  having them here too, as a precaution and to turn them off for
  non-graphical interfaces as well.

* 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))))

* 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
    (setq custom-theme-directory "~/.emacs.d/themes")
    (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

* Scroll compilation window                              :compilation:

  Even though I don't need to see the result of the compilation if
  everything went as it should, scroll the output window so that I can
  see whether there are any warnings and I should have a look anyway.

  #+BEGIN_SRC emacs-lisp
    (setq compilation-scroll-output t)
  #+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 'lua-mode-hook        'flycheck-mode)
    (add-hook 'php-mode-hook        'flycheck-mode)
    (add-hook 'python-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

* Disable the pylint and pyflakes checkers                  :flycheck:

  I use flake8 in =python-mode=, so I have no need for the =python-pylint=
  and =python-pyflakes= checkers. Since this works on a variable that is
  defined in the ~flycheck~ package, it should only run *after* ~flycheck~
  has been loaded.

  #+BEGIN_SRC emacs-lisp
    (eval-after-load "flycheck"
      '(progn
         (mapc (lambda (c) (delq c flycheck-checkers))
               '(python-pylint python-pyflakes))))
  #+END_SRC

* Make ^L look pretty                                           :ppcL:

  Occasionally I might put a ~^L~ character in some code to create a
  page separator. But seeing ~^L~ there isn't all that pretty, not when
  you have something like ~pp^L-mode~. Show a line of ~-~ all the way to
  the =fill-column= - =1=. To do this we should also remove the prefix.

  If the variable =fci-rule-colum= is bound, use that, so that it
  always goes up-to, but not beyond the little red line shown at the
  right margin.

  #+BEGIN_SRC emacs-lisp
    (defun oni:pretty-control-l-function (win)
      "Just make a string of either `fci-rule-column' or
    `fill-column' length -1. Use the `-' character. WIN is ignored."
      (ignore win)
      (make-string
       (1- (if (boundp 'fci-rule-column) fci-rule-column fill-column)) ?-))

    (setq pp^L-^L-string-function 'oni:pretty-control-l-function
          pp^L-^L-string-pre      nil)
  #+END_SRC

  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)

  #+END_SRC

* Auto-join some channels in ERC                                 :erc:

  If ever I log in to IRC with ERC I would like to join these
  channels, seeing as how *if* I talk, it's usually in one of these.
  Though it's rare.

  #+BEGIN_SRC emacs-lisp
    (setq erc-autojoin-channels-alist
          '(("freenode.net" "#ninthfloor" "#emacs" "#dispass")))
  #+END_SRC

* Don't show part messages in ERC                                :erc:

  They don't interest me.

  #+BEGIN_SRC emacs-lisp
    (setq erc-hide-list '("PART"))
  #+END_SRC

  I used to hide more messages, but I found out that it can be
  confusing to not be able to see *any* joins and quits at all.

* Move the timestamp in ERC                                      :erc:

  I prefer having a timestamp on the left-side of a message in the
  form of ~00:00~ instead of te usual. Having it right-aligned messes up
  the non-filled text and having it only show up when it's changed
  makes the buffer messy.

  #+BEGIN_SRC emacs-lisp
    (setq erc-insert-timestamp-function      'erc-insert-timestamp-left
          erc-timestamp-format               "[%H:%M] "

  #+END_SRC

* Set IRC nickname                                               :erc:

  #+END_SRC

* Turn off filling in ERC                                        :erc:

  #+BEGIN_SRC emacs-lisp

  #+END_SRC

* Specify some visual commands for eshell                     :eshell:

  Eshell uses buffered input, always, but some commands need
  unbuffered input, put those commands in =eshell-visual-commands= to
  have them open in a dedicated =*term*= buffer. Since this variable is
  defined in the ~em-term~ module, it should only be changed after shis
  module loads.

  #+BEGIN_SRC emacs-lisp
    (eval-after-load "em-term"
      '(add-to-list 'eshell-visual-commands "unison"))
  #+END_SRC

* Disable prompt highlighting in eshell                       :eshell:

  Since I'm using a custom prompt with some custom colors I don't need
  the eshell prompt to be highlighted, which overwrites any colors I
  specify.

  #+BEGIN_SRC emacs-lisp
    (setq eshell-highlight-prompt nil)
  #+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

* 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

* 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.

  Since I don't ever get any mail from people that use right-to-left
  text, and even if I did I wouldn't be able to read it, I don't need
  bidirectional text support. You shouldn't actually disable it (if
  that's even still possible) since, supposedly, it is an integral
  part of the display engine now, but telling it to always use
  left-to-right should keep it from slowing your emacs down.

  #+BEGIN_SRC emacs-lisp

* 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

* 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

* 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

* Enable history                                              :jabber:

  Enable chat history for both regular chats and multi-user chats. I
  disabled history completely for a long time, but sometimes you miss
  things that way. Store history in per-contact files under
  ~HOME/.emacs.d/jabber-hist~.

  #+BEGIN_SRC emacs-lisp

  #+END_SRC

* Setup accounts for jabber                                   :jabber:

  Each account should have the current hostname appended to its
  account name, so that multiple PCs can log in on the same account at
  the same time and it's easy to note from where I'm talking.

  #+BEGIN_SRC emacs-lisp

* Have ido ignore certain buffers                                :ido:

  These buffers are either uninteresting, reached through other means
  (such as a special keybinding) or they get in the way of how I work.
  For any or all of these reasons I wish to ignore them.

  - ~^\\`\s~ :: Any buffers that start with a space should be ignored.

  - ~^irc\\.~ :: Any buffer that starts with ~irc.~ is a buffer that has
               informational messages on the irc server I'm connected
               to, these don't change often and have other ways of
               grabbing my attention. If I need them I will find them.

  - ~^\\#~ :: Any buffer starting with an ~#~ is most-likely an IRC chat
            buffer, these have ways of letting me know it there is
            anything interesting going on there, I don't usually need
            them clogging up my ido.

  - ~^\\*Customize Option:~ :: Anything starting with ~*Customize Option:~
       is part of Emacs's customize interface and thus doesn't need to
       be shown in the ido buffer list.

  - ~*-jabber-roster-*~ :: Is also accessible through ~f6~, so no need for
       it in my ido list.

  - ~*Messages*~ :: Also accessible through ~C-h e~, so no need for it.

  - ~*fsm-debug*~ :: A buffer used by ~jabber.el~ to track some debug
                   information, I have never had to look at it yet.

  - ~*magit-process*~ :: The buffer where magit's git process runs,
       usually accessible with ~$~ from any magit buffer, and the only
       other time I need to find is if I have to kill it to reset
       magit's process.

  - ~*magit-edit-log*~ :: The commit message buffer from magit. Usually
       accessible with ~C-c c~ if needed.

  - ~*Backtrace*~ :: Usually only interesting for as long as I'm looking
                   at it, if I bury it, I usually don't need it
                   anymore.

  - ~*Ibuffer*~ :: is reached by the key compination ~C-x C-b~, is
                 therefore not needed to show up when using ido, and
                 even gets glitchy when using ido, because the
                 information doesn't get updated.

  Since this requires a variable defined in the ~ido~ module, delay
  execution until it is loaded.

  #+BEGIN_SRC emacs-lisp

      (setq ido-ignore-buffers

* Disable automatic merging in ido                               :ido:

  ido has this wonderful/infuriating feature of trying to correct your
  mistakes by suggesting files in other directories if it can't find
  the file you wish to open in the current directory. This becomes
  bothersome especially when working with django, since the same files
  tend to show up in several directories. Disable it.

  According to the docstring this should be a way to disable it,
  previously I just used a very long timeout by setting
  =ido-auto-merge-delay-time= to ~1000000~.

  #+BEGIN_SRC emacs-lisp
    (setq ido-auto-merge-work-directories-length -1)
  #+END_SRC

* Instruct ido to open buffers in selected window                :ido:

  By default, when more than one frame exists and you try to switch
  to a buffer that is already visible in another frame, ido pops up
  the other frame. This is not what I want, just open the buffer in
  the selected window no matter what.

  #+BEGIN_SRC emacs-lisp
    (setq ido-default-buffer-method 'selected-window)
  #+END_SRC

* Minimize maximum minibuffer height for ido                     :ido:

  I hate it when the minibuffer gets bigger than one line, so don't
  let ido do that.

  #+BEGIN_SRC emacs-lisp
    (setq ido-max-window-height 1)
  #+END_SRC

* Don't save history for ido                                     :ido:

  I don't see the point in saving that history.

  #+BEGIN_SRC emacs-lisp
    (setq ido-save-directory-list-file nil)
  #+END_SRC

* Turn on ido-mode                                               :ido:

  =ido-mode= is an excellent file and buffer selection tool, it
  improves upon regular selection in numerous ways.

  #+BEGIN_SRC emacs-lisp
    (ido-mode)
  #+END_SRC

* Exclude functions from ido-ubiquitous               :ido_ubiquitous:

  Not all functions work well with =ido-ubiquitous-mode=, like
  =org-refile=, so exclude them from using =ido-ubiquitous-mode=.

  #+BEGIN_SRC emacs-lisp
    (setq ido-ubiquitous-command-exceptions '(org-refile org-capture-refile))
  #+END_SRC

* Enable ido-ubiquitous-mode                          :ido_ubiquitous:

  =ido-ubiquitous-mode= lets you use ido for almost anything! Anything
  which looks and acts like file or buffer selection anyway.

  Since it is installed with ELPA, wait until /after/ emacs has been
  initialized.

  #+BEGIN_SRC emacs-lisp
    (add-hook 'emacs-startup-hook 'ido-ubiquitous-mode)
  #+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

* Use electric default in minibuffer                      :minibuffer:

  The =minibuffer-electric-default-mode= hides the default value if you
  start typing. This leaves more room for typing. I also want the
  "short" default indicator (~[default]~ instead of ~(default: default)~).

  #+BEGIN_SRC emacs-lisp
    (setq minibuffer-eldef-shorten-default t)
    (minibuffer-electric-default-mode)
  #+END_SRC

* Don't show help message on empty parts                   :mode_line:

  When hovering the mouse over empty parts of the mode-line, just show
  nothing, don't clutter up my echo area and ~*Messages*~ buffer.

  #+BEGIN_SRC emacs-lisp
    (setq mode-line-default-help-echo "")
  #+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
    (eval-after-load "jedi" '(setcar jedi:server-command "python2"))
    (add-hook 'python-mode-hook 'jedi:setup)
  #+END_SRC

* Don't use a tooltip                                           :jedi:

  The coolest thing about jedi is its eldoc-like argument display. If
  it can figure out what the arguments are they're shown. But please
  don't use tooltips, just the echo area.

  #+BEGIN_SRC emacs-lisp
    (setq jedi:tooltip-method nil)
  #+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

  #+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

* Use 4 spaces per indentation level

  Often I see 8 being used, but that just seems too wide to me.

  #+BEGIN_SRC emacs-lisp
    (setq-default c-basic-offset 4
                  tab-width      4)
  #+END_SRC

* Place fill-column-indicator                  :fill_column_indicator:

  Place the ruler one character farther than what I usually prefer to
  have my lines wrap to, this will indicate where it should not cross,
  not where it should not continue.

  #+BEGIN_SRC emacs-lisp
    (setq-default fci-rule-column 73)
  #+END_SRC

* Disable use of tabs

  By default, use spaces, not tabs. Tabs are madness.

  #+BEGIN_SRC emacs-lisp
    (setq-default indent-tabs-mode nil)
  #+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

* Ensure a final newline

  When looking at diffs, it can be annoying to have 2 extra line
  changes, just because te previous last line suddenly gets a newline
  and the new one doesn't. Plus it's very uniform to have a ~\n~ at the
  end of _every_ line.

  #+BEGIN_SRC emacs-lisp
    (setq-default require-final-newline t)
  #+END_SRC

* Truncate lines

  Just let most line run off the screen. I don't like wrapping my code
  around. I shouldn't make my lines too long in the first place, but
  in case I have a very small window I prefer the lines to remain
  unchanged, visually.

  #+BEGIN_SRC emacs-lisp
    (setq-default truncate-lines t)
  #+END_SRC

* Send appointments to jabber                                 :jabber:

  When an appointment is coming up, show me in a buffer, but also
  send a message to my jabber account.

  #+BEGIN_SRC emacs-lisp
    (setq appt-disp-window-function #'oni:appt-display-window-and-jabber)
  #+END_SRC

* Don't display diary when appt is initialized                  :appt:

  If the diary is displayed after the initialization of =appt= I would
  get a diary buffer each time I load =org-mode=. Since I don't use the
  diary, except for what =org-mode= puts in there for notifications and
  such, I really don't want to see it, ever.

  #+BEGIN_SRC emacs-lisp
    (setq appt-display-diary nil)
  #+END_SRC

* Don't case fold with auto modes

  I haven't had to deal with wrongly-cased filenames since I stopped
  using windows.

  #+BEGIN_SRC emacs-lisp
    (setq auto-mode-case-fold nil)
  #+END_SRC

* Save all auto saves in /tmp

  Having auto save files everywhere cloggs up the filesystem. Move
  them all into ~/tmp~, though I should probably use a less volatile
  location.

  #+BEGIN_SRC emacs-lisp
    (setq auto-save-file-name-transforms
          `((".*" "~/.local/share/emacs/autosave/" t)))
  #+END_SRC

* Save all backup files to /tmp

  Having backuf files everywhere also cloggs up the filesystem. Move
  them all into ~/tmp~ as well, though here too I should probably use a
  less volatile location.

  #+BEGIN_SRC emacs-lisp
    (setq backup-directory-alist `((".*" . "~/.local/share/emacs/backup/")))
  #+END_SRC

* Automatically determine browser                             :browse:

  Use the =BROWSER= environment variable to figure out which browser to
  call for =browse-url=. And use the =browse-url-generic= function to open
  urls, otherwise this setting would have no meaning.

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

* Customize C indentation                                          :c:

  When writing C code, when calling a function I prefer the
  indentation to look like:

  #+BEGIN_SRC c :tangle no
    call_some_function(
        argument1,
        argument2
    );
  #+END_SRC

  To be able to shorten lines with long function calls. As opposed to
  the default:

  #+BEGIN_SRC c :tangle no
    call_some_function(
                       argument1,
                       argument2,
                       );
  #+END_SRC

  Which doesn't really help in making lines shorter. And I also
  happen to think it looks hideous.

  #+BEGIN_SRC emacs-lisp

  #+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

* Setup some frame parameters

  Disable borders, disable scroll-bars, tool-bars and menu-bars (this
  is the third place I'm doing this, I *really* want them gone, don't
  I). And set the preferred font.

  #+BEGIN_SRC emacs-lisp

* Stop elnode from running automatically                      :elnode:

  I like elnode, but it really should stop starting itself up every

  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

* 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

* Change gnus init file

  My gnus init file is separate, since I don't always immediately use
  gnus.

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

* Automatically update gtags TAGS                              :gtags:

  Before there was this option I had some complicated function to do
  the same thing from somewhere, now that isn't necessary anymore.

  #+BEGIN_SRC emacs-lisp
    (setq gtags-auto-update t)
  #+END_SRC

* Display help-at-point

  When the cursor is in a location where a help message would be
  shown by hovering the mouse over it, show that help after a short
  time of idling on that spot. Another step in using no mouse
  whatsoever without losing any functionality.

  #+BEGIN_SRC emacs-lisp
    (setq help-at-pt-display-when-idle t)
  #+END_SRC

* Set inferior lisp program to SBCL                             :lisp:

  SBCL seems like a very good Lisp implementation to use, widely
  supported by packagers too. =--noinform= keeps the copyright message
  from showing up and =--no-linedit= is used by the =linedit= package to
  determine that it shouldn't be enabled.

  #+BEGIN_SRC emacs-lisp
    (setq inferior-lisp-program "sbcl --noinform --no-linedit")
  #+END_SRC

* Inhibit stuff

  I don't need to see the startup message, I don't want the default
  init messing with my own stuff and I don't even know what
  =inhibit-local-menu-bar-menus= does, but it doesn't sound like I need
  is, since I don't use menu bars.

  #+BEGIN_SRC emacs-lisp
    (setq inhibit-default-init         t
          inhibit-local-menu-bar-menus t
          inhibit-startup-message      t)
  #+END_SRC

* Change the initial major mode and message

  The =lisp-interaction-mode= is a nice idea on paper, but usually when
  I want to use the ~*scratch*~ buffer, it just gets in my way, so use
  =emacs-lisp-mode= instead. Also, by now I know what the ~*scratch*~
  buffer is for, so I really don't need that message telling me what
  it does.

  #+BEGIN_SRC emacs-lisp
    (setq initial-major-mode      'emacs-lisp-mode
          initial-scratch-message nil)
  #+END_SRC

* Store jabber avatar cache under .emacs.d                    :jabber:

  Even though I don't use avatars anymore I don't want ~jabber.el~
  creating directories all over the place, so just to be safe I put
  it under ~HOME/.emacs.d~.

  #+BEGIN_SRC emacs-lisp
    (setq jabber-avatar-cache-directory "~/.emacs.d/jabber-avatars/")
  #+END_SRC

* Setup formats                                               :jabber:

  Most of the time I prefer having my message start at the beginning
  of the line, in case someone sends me a piece of code or I send
  them some, it's easier to read if you don't have to change it first.

  But that leaves a lot of empty space on that prompt line, best fill
  it up as mucha as is still useful.

  Also show the chat buffer names as just the contact's name prefixed
  with a ~+~ to keep them short and clean.

  #+BEGIN_SRC emacs-lisp
    (setq jabber-chat-buffer-format         "+%n"
          jabber-chat-foreign-prompt-format "%t %u/%r <\n"
          jabber-chat-local-prompt-format   "%t %u/%r >\n"
          jabber-groupchat-buffer-format    "++%n"
          jabber-groupchat-prompt-format    "%t %u --\n")
  #+END_SRC

* Don't use avatars                                           :jabber:

  I did for a while, but since there is no concensus over what is
  good and what is bad, buffers start looking messy, so I just
  disabled them completely. I know most of the people I chat with
  personally, so it doesn't really add much anyway.

  #+BEGIN_SRC emacs-lisp
    (setq jabber-chat-buffer-show-avatar nil
          jabber-vcard-avatars-publish   nil
          jabber-vcard-avatars-retrieve  nil)
  #+END_SRC

* Don't fill                                                  :jabber:

  Just like ERC, don't fill lines so that =visual-line-mode= can do
  its thing.

  #+BEGIN_SRC emacs-lisp
    (setq jabber-chat-fill-long-lines nil)
  #+END_SRC

* Don't send chatstates                                       :jabber:

  Don't let people know what I'm doing, don't send them information
  on that I'm typing or not, etc. This isn't very useful and it
  sometimes creates confusion when I accidentally start typing in the
  wrong buffer.

  #+BEGIN_SRC emacs-lisp
    (setq jabber-chatstates-confirm nil)
  #+END_SRC

* Autojoin some channels                                      :jabber:

  Just one, really, the only one I'm in.

  #+BEGIN_SRC emacs-lisp
    (setq jabber-muc-autojoin '("aethon@muc.ryuslash.org"))
  #+END_SRC

* Keep the roster buffer clean                                :jabber:

  Most of the time I really don't need to see the keybindings for the
  roster buffers, so hide them initially. And the offline contacts as
  well.

  #+BEGIN_SRC emacs-lisp
    (setq jabber-roster-show-bindings nil)
    (setq jabber-show-offline-contacts nil)
  #+END_SRC

* Defer font locking a little                               :fontlock:

  By deferring font-lock for a very short time it should improve
  scrolling performance.

  #+BEGIN_SRC emacs-lisp
    (setq jit-lock-defer-time 0.2)
  #+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)
         (emms-default-players)

         (require 'emms-player-mpd)
         (add-to-list 'emms-player-list 'emms-player-mpd)
         (setq emms-player-mpd-music-directory "/mnt/music/mp3")

         (require 'emms-mode-line)
         (setq emms-mode-line-mode-line-function 'oni:mode-line-current-song)
         (emms-mode-line 1)))
