+# About
+
+This is a Emacs configuration file written in `org-mode`. There are a few
+reasons why I wanted to do this. My `.emacs.d/` was a mess, and needed a
+proper clean-up. Also I like keeping all my configurations in a single
+file, using `org-mode` I can keep this file *organized*. I aim to briefly
+explain all my configurations.
+
+# Configurations
+
+## Meta
+
+Emacs can only load `.el`-files. We can use `C-c C-v t` to run
+`org-babel-tangle`, which extracts the code blocks from the current file
+into a source-specific file (in this case a `.el`-file).
+
+To avoid doing this each time a change is made we can add a function to
+the `after-save-hook` ensuring to always tangle and byte-compile the
+`org`-document after changes.
+
+```lisp
+(defun init-hook ()
+ "If the current buffer is 'init.org' the code-blocks are
+tangled, and the tangled file is compiled."
+ (when (equal (buffer-file-name)
+ (expand-file-name (concat user-emacs-directory "init.org")))
+ (org-babel-tangle)
+ (byte-compile-file (concat user-emacs-directory "init.el"))))
+
+(add-hook 'after-save-hook 'init-hook)
+```
+
+## Package
+
+Managing extensions for Emacs is simplified using `package` which
+is built in to Emacs 24 and newer. To load downloaded packages we
+need to initialize `package`.
+
+```lisp
+(require 'package)
+(setq package-enable-at-startup nil)
+(package-initialize)
+```
+
+Packages can be fetched from different mirrors, [melpa](http://melpa.milkbox.net/#/) is the largest
+archive and is well maintained.
+
+```lisp
+(add-to-list 'package-archives
+ '("MELPA" . "http://melpa.milkbox.net/packages/") t)
+```
+
+We can define a predicate that tells us wither or not the newest version
+of a package is installed.
+
+```lisp
+(defun newest-package-installed-p (package)
+ "Return true if the newest available PACKAGE is installed."
+ (when (package-installed-p package)
+ (let* ((local-pkg-desc (or (assq package package-alist)
+ (assq package package--builtins)))
+ (newest-pkg-desc (assq package package-archive-contents)))
+ (and local-pkg-desc newest-pkg-desc
+ (version-list-= (package-desc-vers (cdr local-pkg-desc))
+ (package-desc-vers (cdr newest-pkg-desc)))))))
+```
+
+Let's write a function to install a package if it is not installed or
+upgrades it if a new version has been released. Here our predicate comes
+in handy.
+
+```lisp
+(defun upgrade-or-install-package (package)
+ "Unless the newest available version of PACKAGE is installed
+PACKAGE is installed and the current version is deleted."
+ (unless (newest-package-installed-p package)
+ (let ((pkg-desc (assq package package-alist)))
+ (when pkg-desc
+ (package-delete (symbol-name package)
+ (package-version-join
+ (package-desc-vers (cdr pkg-desc)))))
+ (package-install package))))
+```
+
+Also, we will need a function to find all dependencies from a given package.
+
+```lisp
+(defun dependencies (package)
+ "Returns a list of dependencies from a given PACKAGE."
+ (let* ((pkg-desc (assq package package-alist))
+ (reqs (and pkg-desc (package-desc-reqs (cdr pkg-desc)))))
+ (mapcar 'car reqs)))
+```
+
+The `package-refresh-contents` function downloads archive descriptions,
+this is a major bottleneck in this configuration. To avoid this we can
+try to only check for updates once every day or so. Here are three
+variables. The first specifies how often we should check for updates. The
+second specifies wither one should update during the initialization. The
+third is a path to a file where a time-stamp is stored in order to check
+when packages were updated last.
+
+```lisp
+(defvar days-between-updates 1)
+(defvar do-package-update-on-init t)
+(defvar package-last-update-file
+ (expand-file-name (concat user-emacs-directory ".package-last-update")))
+```
+
+The tricky part is figuring out when the last time the Emacs was updated!
+Here is a hacky way of doing it, using [time-stamps](http://www.gnu.org/software/emacs/manual/html_node/emacs/Time-Stamps.html). By adding a
+time-stamp to the a file, we can determine wither or not to do an
+update. After that we must run the `time-stamp`-function to update the
+time-stamp.
+
+```lisp
+(require 'time-stamp)
+;; Open the package-last-update-file
+(with-temp-file package-last-update-file
+ (if (file-exists-p package-last-update-file)
+ (progn
+ ;; Insert it's original content's.
+ (insert-file-contents package-last-update-file)
+ (let ((start (re-search-forward time-stamp-start nil t))
+ (end (re-search-forward time-stamp-end nil t)))
+ (when (and start end)
+ ;; Assuming we have found a time-stamp, we check determine if it's
+ ;; time to update.
+ (setq do-package-update-on-init
+ (<= days-between-updates
+ (days-between
+ (current-time-string)
+ (buffer-substring-no-properties start end))))
+ ;; Remember to update the time-stamp.
+ (when do-package-update-on-init
+ (time-stamp)))))
+ ;; If no such file exists it is created with a time-stamp.
+ (insert "Time-stamp: <>")
+ (time-stamp)))
+```
+
+Now we can use the function above to make sure packages are installed and
+up to date. Here are some packages I find useful (some of these
+configurations are also dependent on them).
+
+```lisp
+(when (and do-package-update-on-init
+ (y-or-n-p "Update all packages?"))
+ (package-refresh-contents)
+
+ (let* ((packages
+ '(ac-geiser ; Auto-complete backend for geiser
+ ac-slime ; An auto-complete source using slime completions
+ ace-jump-mode ; quick cursor location minor mode
+ auto-compile ; automatically compile Emacs Lisp libraries
+ auto-complete ; auto completion
+ elscreen ; window session manager
+ expand-region ; Increase selected region by semantic units
+ flx-ido ; flx integration for ido
+ ido-vertical-mode ; Makes ido-mode display vertically.
+ geiser ; GNU Emacs and Scheme talk to each other
+ haskell-mode ; A Haskell editing mode
+ jedi ; Python auto-completion for Emacs
+ magit ; control Git from Emacs
+ markdown-mode ; Emacs Major mode for Markdown-formatted files.
+ matlab-mode ; MATLAB integration with Emacs.
+ monokai-theme ; A fruity color theme for Emacs.
+ move-text ; Move current line or region with M-up or M-down
+ multiple-cursors ; Multiple cursors for Emacs.
+ org ; Outline-based notes management and organizer
+ paredit ; minor mode for editing parentheses
+ powerline ; Rewrite of Powerline
+ pretty-lambdada ; the word `lambda' as the Greek letter.
+ smex ; M-x interface with Ido-style fuzzy matching.
+ undo-tree)) ; Treat undo history as a tree
+ ;; Fetch dependencies from all packages.
+ (reqs (mapcar 'dependencies packages))
+ ;; Append these to the original list, and remove any duplicates.
+ (packages (delete-dups (apply 'append packages reqs))))
+
+ (dolist (package packages)
+ (upgrade-or-install-package package)))
+
+ ;; This package is only relevant for Mac OS X.
+ (when (memq window-system '(mac ns))
+ (upgrade-or-install-package 'exec-path-from-shell))
+ (package-initialize))
+```
+
+## Mac OS X
+
+I run this configuration mostly on Mac OS X, so we need a couple of
+settings to make things work smoothly. In the package section
+`exec-path-from-shell` is included (only if you're running OS X), this is
+to include environment-variables from the shell. It makes useing Emacs
+along with external processes a lot simpler. I also prefer using the
+`Command`-key as the `Meta`-key.
+
+```lisp
+(when (memq window-system '(mac ns))
+ (setq mac-option-modifier nil
+ mac-command-modifier 'meta
+ x-select-enable-clipboard t)
+ (exec-path-from-shell-initialize))
+```
+
+## Require
+
+Some features are not loaded by default to minimize initialization time,
+so they have to be required (or loaded, if you will).
+
+```lisp
+(dolist (feature
+ '(auto-compile ; auto-compile .el files
+ auto-complete-config ; a configuration for auto-complete-mode
+ jedi ; auto-completion for python
+ matlab ; matlab-mode
+ ob-matlab ; org-babel matlab
+ ox-latex ; the latex-exporter (from org)
+ ox-md ; Markdown exporter (from org)
+ pretty-lambdada ; show 'lambda' as the greek letter.
+ recentf ; recently opened files
+ smex ; M-x interface Ido-style.
+ tex-mode)) ; TeX, LaTeX, and SliTeX mode commands
+ (require feature))
+```
+
+## Sane defaults
+
+These are what *I* consider to be saner defaults.
+
+We can set variables to whatever value we'd like using `setq`.
+
+```lisp
+(setq initial-scratch-message nil ; Clean scratch buffer.
+ inhibit-startup-message t ; No splash screen please.
+ default-input-method "TeX" ; Use TeX when toggeling input method.
+ ring-bell-function 'ignore ; Quite as a mouse.
+ doc-view-continuous t ; At page edge goto next/previous.
+ echo-keystrokes 0.1) ; Show keystrokes asap.
+
+;; Some mac-bindings interfere with Emacs bindings.
+(when (boundp 'mac-pass-command-to-system)
+ (setq mac-pass-command-to-system nil))
+
+```
+
+Some variables are buffer-local, so changing them using `setq` will only
+change them in a single buffer. Using `setq-default` we change the
+buffer-local variable's default value.
+
+```lisp
+(setq-default fill-column 76 ; Maximum line width.
+ indent-tabs-mode nil ; Use spaces instead of tabs.
+ split-width-threshold 100 ; Split verticly by default.
+ auto-fill-function 'do-auto-fill) ; Auto-fill-mode everywhere.
+```
+
+The `load-path` specifies where Emacs should look for `.el`-files (or
+Emacs lisp files). I have a directory called `site-lisp` where I keep all
+extensions that have been installed manually (these are mostly my own
+projects).
+
+```lisp
+(let ((default-directory (concat user-emacs-directory "site-lisp/")))
+ (when (file-exists-p default-directory)
+ (normal-top-level-add-to-load-path '("."))
+ (normal-top-level-add-subdirs-to-load-path)))
+```
+
+Answering *yes* and *no* to each question from Emacs can be tedious, a
+single *y* or *n* will suffice.
+
+```lisp
+(fset 'yes-or-no-p 'y-or-n-p)
+```
+
+To avoid file system clutter we put all auto saved files in a single
+directory.
+
+```lisp
+(defvar emacs-autosave-directory
+ (concat user-emacs-directory "autosaves/")
+ "This variable dictates where to put auto saves. It is set to a
+ directory called autosaves located wherever your .emacs.d/ is
+ located.")
+
+;; Sets all files to be backed up and auto saved in a single directory.
+(setq backup-directory-alist
+ `((".*" . ,emacs-autosave-directory))
+ auto-save-file-name-transforms
+ `((".*" ,emacs-autosave-directory t)))
+```
+
+Set `utf-8` as preferred coding system.
+
+```lisp
+(set-language-environment "UTF-8")
+```
+
+By default the `narrow-to-region` command is disabled and issues a
+warning, because it might confuse new users. I find it useful sometimes,
+and don't want to be warned.
+
+```lisp
+(put 'narrow-to-region 'disabled nil)
+```
+
+Call `auto-complete` default configuration, which enables `auto-complete`
+globally.
+
+```lisp
+(ac-config-default)
+```
+
+Automaticly revert `doc-view`-buffers when the file changes on disk.
+
+```lisp
+(add-hook 'doc-view-mode-hook 'auto-revert-mode)
+```
+
+## Modes
+
+There are some modes that are enabled by default that I don't find
+particularly useful. We create a list of these modes, and disable all of
+these.
+
+```lisp
+(dolist (mode
+ '(tool-bar-mode ; No toolbars, more room for text.
+ scroll-bar-mode ; No scroll bars either.
+ blink-cursor-mode)) ; The blinking cursor gets old.
+ (funcall mode 0))
+```
+
+Let's apply the same technique for enabling modes that are disabled by
+default.
+
+```lisp
+(dolist (mode
+ '(abbrev-mode ; E.g. sopl -> System.out.println.
+ auto-compile-on-load-mode ; Compile .el files on load ...
+ auto-compile-on-save-mode ; ... and save.
+ column-number-mode ; Show column number in mode line.
+ delete-selection-mode ; Replace selected text.
+ recentf-mode ; Recently opened files.
+ show-paren-mode ; Highlight matching parentheses.
+ global-undo-tree-mode)) ; Undo as a tree.
+ (funcall mode 1))
+```
+
+This makes `.md`-files open in `markdown-mode`.
+
+```lisp
+(add-to-list 'auto-mode-alist '("\\.md\\'" . markdown-mode))
+```
+
+## Visual
+
+Change the color-theme to `monokai` (downloaded using `package`).
+
+```lisp
+(load-theme 'monokai t)
+```
+
+Use the [Inconsolata](http://www.levien.com/type/myfonts/inconsolata.html) font if it's installed on the system.
+
+```lisp
+(when (member "Inconsolata-g" (font-family-list))
+ (set-face-attribute 'default nil :font "Inconsolata-g-11"))
+```
+
+[Powerline](https://github.com/milkypostman/powerline) is an extension to customize the mode line. This is modified
+version `powerline-nano-theme`.
+
+```lisp
+(setq-default
+ mode-line-format
+ '("%e"
+ (:eval
+ (let* ((active (powerline-selected-window-active))
+ ;; left hand side displays Read only or Modified.
+ (lhs (list (powerline-raw
+ (cond (buffer-read-only "Read only")
+ ((buffer-modified-p) "Modified")
+ (t "")) nil 'l)))
+ ;; right side hand displays (line,column).
+ (rhs (list
+ (powerline-raw
+ (concat
+ "(" (number-to-string (line-number-at-pos))
+ "," (number-to-string (current-column)) ")") nil 'r)))
+ ;; center displays buffer name.
+ (center (list (powerline-raw "%b" nil))))
+ (concat (powerline-render lhs)
+ (powerline-fill-center nil (/ (powerline-width center) 2.0))
+ (powerline-render center)
+ (powerline-fill nil (powerline-width rhs))
+ (powerline-render rhs))))))
+```
+
+This is what it looks like:
+
+![img](./powerline.png)
+
+## Ido
+
+Interactive do (or `ido-mode`) changes the way you switch buffers and
+open files/directories. Instead of writing complete file paths and buffer
+names you can write a part of it and select one from a list of
+possibilities. Using `ido-vertical-mode` changes the way possibilities
+are displayed, and `flx-ido-mode` enables fuzzy matching.
+
+```lisp
+(dolist (mode
+ '(ido-mode ; Interactivly do.
+ ido-everywhere ; Use Ido for all buffer/file reading.
+ ido-vertical-mode ; Makes ido-mode display vertically.
+ flx-ido-mode)) ; Toggle flx ido mode.
+ (funcall mode 1))
+```
+
+We can set the order of file selections in `ido`. I prioritize source
+files along with `org`- and `tex`-files.
+
+```lisp
+(setq ido-file-extensions-order
+ '(".el" ".scm" ".lisp" ".java" ".c" ".h" ".org" ".tex"))
+```
+
+Sometimes when using `ido-switch-buffer` the `*Messages*` buffer get in
+the way, so we set it to be ignored (it can be accessed using `C-h e`, so
+there is really no need for it in the buffer list).
+
+```lisp
+(add-to-list 'ido-ignore-buffers "*Messages*")
+```
+
+To make `M-x` behave more like `ido-mode` we can use the `smex`
+package. It needs to be initialized, and we can replace the binding to
+the standard `execute-extended-command` with `smex`.
+
+```lisp
+(smex-initialize)
+(global-set-key (kbd "M-x") 'smex)
+```
+
+## Calendar
+
+Define a function to display week numbers in `calender-mode`. The snippet
+is from [EmacsWiki](http://www.emacswiki.org/emacs/CalendarWeekNumbers).
+
+```lisp
+(defun calendar-show-week (arg)
+ "Displaying week number in calendar-mode."
+ (interactive "P")
+ (copy-face font-lock-constant-face 'calendar-iso-week-face)
+ (set-face-attribute
+ 'calendar-iso-week-face nil :height 0.7)
+ (setq calendar-intermonth-text
+ (and arg
+ '(propertize
+ (format
+ "%2d"
+ (car (calendar-iso-from-absolute
+ (calendar-absolute-from-gregorian
+ (list month day year)))))
+ 'font-lock-face 'calendar-iso-week-face))))
+```
+
+Evaluate the `calendar-show-week` function.
+
+```lisp
+(calendar-show-week t)
+```
+
+Set Monday as the first day of the week, and set my location.
+
+```lisp
+(setq calendar-week-start-day 1
+ calendar-latitude 60.0
+ calendar-longitude 10.7
+ calendar-location-name "Oslo, Norway")
+```
+
+## Mail
+
+I use [mu4e](http://www.djcbsoftware.nl/code/mu/mu4e.html) (which is a part of [mu](http://www.djcbsoftware.nl/code/mu/)) along with [offlineimap](http://docs.offlineimap.org/en/latest/) on one of my
+computers. Because the mail-setup wont work without these programs
+installed we bind `load-mail-setup` to `nil`. If the value is changed to
+a `non-nil` value mail is setup.
+
+```lisp
+(defvar load-mail-setup nil)
+
+(when load-mail-setup
+ ;; We need mu4e
+ (require 'mu4e)
+
+ ;; Some basic mu4e settings.
+ (setq mu4e-maildir "~/.ifimail" ; top-level Maildir
+ mu4e-sent-folder "/INBOX.Sent" ; folder for sent messages
+ mu4e-drafts-folder "/INBOX.Drafts" ; unfinished messages
+ mu4e-trash-folder "/INBOX.Trash" ; trashed messages
+ mu4e-refile-folder "/INBOX.Archive" ; saved messages
+ mu4e-get-mail-command "offlineimap" ; offlineimap to fetch mail
+ mu4e-compose-signature "- Lars" ; Sign my name
+ mu4e-update-interval (* 5 60) ; update every 5 min
+ mu4e-confirm-quit nil ; just quit
+ mu4e-view-show-images t ; view images
+ mu4e-html2text-command
+ "html2text -utf8") ; use utf-8
+
+ ;; Setup for sending mail.
+ (setq user-full-name
+ "Lars Tveito" ; Your full name
+ user-mail-address
+ "larstvei@ifi.uio.no" ; And email-address
+ smtpmail-smtp-server
+ "smtp.uio.no" ; Host to mail-server
+ smtpmail-smtp-service 465 ; Port to mail-server
+ smtpmail-stream-type 'ssl ; Protocol used for sending
+ send-mail-function 'smtpmail-send-it ; Use smpt to send
+ mail-user-agent 'mu4e-user-agent) ; Use mu4e!
+
+ ;; Register file types that can be handled by ImageMagick.
+ (when (fboundp 'imagemagick-register-types)
+ (imagemagick-register-types))
+
+;; (defadvice mu4e (before show-mu4e (arg) activate)
+;; "Always show mu4e in fullscreen and remember window
+;; configuration."
+;; (unless arg
+;; (window-configuration-to-register :mu4e-fullscreen)
+;; (mu4e-update-mail-and-index t)
+;; (delete-other-windows)))
+
+;; (defadvice mu4e-quit (after restore-windows nil activate)
+;; "Restore window configuration."
+;; (jump-to-register :mu4e-fullscreen))
+
+ ;; Overwrite the native 'compose-mail' binding to 'show-mu4e'.
+ (global-set-key (kbd "C-x m") 'mu4e))
+```
+
+## Flyspell
+
+Flyspell offers on-the-fly spell checking. We can enable flyspell for all
+text-modes with this snippet.
+
+```lisp
+(add-hook 'text-mode-hook 'turn-on-flyspell)
+```
+
+To use flyspell for programming there is `flyspell-prog-mode`, that only
+enables spell checking for comments and strings. We can enable it for all
+programming modes using the `prog-mode-hook`. Flyspell interferes with
+auto-complete mode, but there is a workaround provided by auto complete.
+
+```lisp
+(add-hook 'prog-mode-hook 'flyspell-prog-mode)
+(ac-flyspell-workaround)
+```
+
+To cycle through dictionary's we can define a variable containing a
+cyclic list of installed language packs.
+
+```lisp
+(defvar ispell-languages '#1=("english" "norsk" . #1#))
+```
+
+Now we only need a small function to change set the language and shift
+the list.
+
+```lisp
+(defun cycle-languages ()
+ "Changes the ispell-dictionary to whatever is the next (or cdr) in the
+LANGUAGES (cyclic) list."
+ (interactive)
+ (ispell-change-dictionary
+ (car (setq ispell-languages (cdr ispell-languages)))))
+```
+
+## Org
+
+I use `org-agenda` for appointments and such.
+
+```lisp
+(setq org-agenda-start-on-weekday nil ; Show agenda from today.
+ org-agenda-files '("~/Dropbox/life.org") ; A list of agenda files.
+ org-agenda-default-appointment-duration 120) ; 2 hours appointments.
+```
+
+When editing org-files with source-blocks, we want the source blocks to
+be themed as they would in their native mode.
+
+```lisp
+(setq org-src-fontify-natively t)
+```
+
+## Interactive functions
+
+
+
+To search recent files useing `ido-mode` we add this snippet from
+[EmacsWiki](http://www.emacswiki.org/emacs/CalendarWeekNumbers).
+
+```lisp
+(defun recentf-ido-find-file ()
+ "Find a recent file using Ido."
+ (interactive)
+ (let ((f (ido-completing-read "Choose recent file: " recentf-list nil t)))
+ (when f
+ (find-file f))))
+```
+
+`just-one-space` removes all whitespace around a point - giving it a
+negative argument it removes newlines as well. We wrap a interactive
+function around it to be able to bind it to a key.
+
+```lisp
+(defun remove-whitespace-inbetween ()
+ "Removes whitespace before and after the point."
+ (interactive)
+ (just-one-space -1))
+```
+
+This interactive function switches you to a `shell`, and if triggered in
+the shell it switches back to the previous buffer.
+
+```lisp
+(defun switch-to-shell ()
+ "Jumps to eshell or back."
+ (interactive)
+ (if (string= (buffer-name) "*shell*")
+ (switch-to-prev-buffer)
+ (shell)))
+```
+
+To duplicate either selected text or a line we define this interactive
+function.
+
+```lisp
+(defun duplicate-thing ()
+ "Ethier duplicates the line or the region"
+ (interactive)
+ (save-excursion
+ (let ((start (if (region-active-p) (region-beginning) (point-at-bol)))
+ (end (if (region-active-p) (region-end) (point-at-eol))))
+ (goto-char end)
+ (unless (region-active-p)
+ (newline))
+ (insert (buffer-substring start end)))))
+```
+
+To tidy up a buffer we define this function borrowed from [simenheg](https://github.com/simenheg).
+
+```lisp
+(defun tidy ()
+ "Ident, untabify and unwhitespacify current buffer, or region if active."
+ (interactive)
+ (let ((beg (if (region-active-p) (region-beginning) (point-min)))
+ (end (if (region-active-p) (region-end) (point-max))))
+ (indent-region beg end)
+ (whitespace-cleanup)
+ (untabify beg (if (< end (point-max)) end (point-max)))))
+```
+

+
+## Advice
+
+An advice can be given to a function to make it behave differently. This
+advice makes `eval-last-sexp` (bound to `C-x C-e`) replace the sexp with
+the value.
+
+```lisp
+(defadvice eval-last-sexp (around replace-sexp (arg) activate)
+ "Replace sexp when called with a prefix argument."
+ (if arg
+ (let ((pos (point)))
+ ad-do-it
+ (goto-char pos)
+ (backward-kill-sexp)
+ (forward-sexp))
+ ad-do-it))
+```
+
+`Flyspell` signals an error if there is no spell-checking tool is
+installed. We can advice `turn-on=flyspell` and `flyspell-prog-mode` to
+only try to enable `flyspell` if a spell-checking tool is avalible.
+
+```lisp
+(defadvice turn-on-flyspell (around check nil activate)
+ "Turns on flyspell only if a spell-checking tool is installed."
+ (when (executable-find ispell-program-name)
+ ad-do-it))
+```
+
+```lisp
+(defadvice flyspell-prog-mode (around check nil activate)
+ "Turns on flyspell only if a spell-checking tool is installed."
+ (when (executable-find ispell-program-name)
+ ad-do-it))
+```
+
+# Language mode specific
+
+## Lisp
+
+`Pretty-lambda` provides a customizable variable
+`pretty-lambda-auto-modes` that is a list of common lisp modes. Here we
+can add some extra lisp-modes. We run the `pretty-lambda-for-modes`
+function to activate `pretty-lambda-mode` in lisp modes.
+
+```lisp
+(dolist (mode '(slime-repl-mode geiser-repl-mode))
+ (add-to-list 'pretty-lambda-auto-modes mode))
+
+(pretty-lambda-for-modes)
+```
+
+I use `Paredit` when editing lisp code, we enable this for all lisp-modes
+in the `pretty-lambda-auto-modes` list.
+
+```lisp
+(dolist (mode pretty-lambda-auto-modes)
+ ;; add paredit-mode to all mode-hooks
+ (add-hook (intern (concat (symbol-name mode) "-hook")) 'paredit-mode))
+```
+
+### Emacs Lisp
+
+In `emacs-lisp-mode` we can enable `eldoc-mode` to display information
+about a function or a variable in the echo area.
+
+```lisp
+(add-hook 'emacs-lisp-mode-hook 'turn-on-eldoc-mode)
+(add-hook 'lisp-interaction-mode-hook 'turn-on-eldoc-mode)
+```
+
+### Common lisp
+
+I use [Slime](http://www.common-lisp.net/project/slime/) along with `lisp-mode` to edit Common Lisp code. Slime
+provides code evaluation and other great features, a must have for a
+Common Lisp developer. [Quicklisp](http://www.quicklisp.org/beta/) is a library manager for Common Lisp,
+and you can install Slime following the instructions from the site along
+with this snippet.
+
+```lisp
+(when (file-exists-p "~/quicklisp/slime-helper.elc")
+ (load (expand-file-name "~/quicklisp/slime-helper.elc")))
+```
+
+We can specify what Common Lisp program Slime should use (I use SBCL).
+
+```lisp
+(setq inferior-lisp-program "sbcl")
+```
+
+To improve auto completion for Common Lisp editing we can use `ac-slime`
+which uses slime completions as a source.
+
+```lisp
+(add-hook 'slime-mode-hook 'set-up-slime-ac)
+(add-hook 'slime-repl-mode-hook 'set-up-slime-ac)
+
+(eval-after-load "auto-complete"
+ '(add-to-list 'ac-modes 'slime-repl-mode))
+```
+
+### Scheme
+
+[Geiser](http://www.nongnu.org/geiser/) provides features similar to Slime for Scheme editing. Everything
+works pretty much out of the box, we only need to add auto completion,
+and specify which scheme-interpreter we prefer.
+
+```lisp
+(add-hook 'geiser-mode-hook 'ac-geiser-setup)
+(add-hook 'geiser-repl-mode-hook 'ac-geiser-setup)
+(eval-after-load "auto-complete"
+ '(add-to-list 'ac-modes 'geiser-repl-mode))
+(setq geiser-active-implementations '(racket))
+```
+
+## Java and C
+
+The `c-mode-common-hook` is a general hook that work on all C-like
+languages (C, C++, Java, etc…). I like being able to quickly compile
+using `C-c C-c` (instead of `M-x compile`), a habit from `latex-mode`.
+
+```lisp
+(defun c-setup ()
+ (local-set-key (kbd "C-c C-c") 'compile))
+
+(require 'auto-complete-c-headers)
+(add-to-list 'ac-sources 'ac-source-c-headers)
+
+(add-hook 'c-mode-common-hook 'c-setup)
+```
+
+Some statements in Java appear often, and become tedious to write
+out. We can use abbrevs to speed this up.
+
+```lisp
+(define-abbrev-table 'java-mode-abbrev-table
+ '(("psv" "public static void main(String[] args) {" nil 0)
+ ("sopl" "System.out.println" nil 0)
+ ("sop" "System.out.printf" nil 0)))
+```
+
+To be able to use the abbrev table defined above, `abbrev-mode` must be
+activated.
+
+```lisp
+(defun java-setup ()
+ (abbrev-mode t)
+ (setq-local compile-command (concat "javac " (buffer-name))))
+
+(add-hook 'java-mode-hook 'java-setup)
+```
+
+## Assembler
+
+When writing assembler code I use `#` for comments. By defining
+`comment-start` we can add comments using `M-;` like in other programming
+modes. Also in assembler should one be able to compile using `C-c C-c`.
+
+```lisp
+(defun asm-setup ()
+ (setq comment-start "#")
+ (local-set-key (kbd "C-c C-c") 'compile))
+
+(add-hook 'asm-mode-hook 'asm-setup)
+```
+
+## LaTeX
+
+`.tex`-files should be associated with `latex-mode` instead of
+`tex-mode`.
+
+```lisp
+(add-to-list 'auto-mode-alist '("\\.tex\\'" . latex-mode))
+```
+
+I like using the [Minted](https://code.google.com/p/minted/) package for source blocks in LaTeX. To make org
+use this we add the following snippet.
+
+```lisp
+(add-to-list 'org-latex-packages-alist '("" "minted"))
+(setq org-latex-listings 'minted)
+```
+
+Because [Minted](https://code.google.com/p/minted/) uses [Pygments](http://pygments.org) (an external process), we must add the
+`-shell-escape` option to the `org-latex-pdf-process` commands. The
+`tex-compile-commands` variable controls the default compile command for
+Tex- and LaTeX-mode, we can add the flag with a rather dirty statement
+(if anyone finds a nicer way to do this, please let me know).
+
+```lisp
+(setq org-latex-pdf-process
+ (mapcar
+ (lambda (str)
+ (concat "pdflatex -shell-escape "
+ (substring str (string-match "-" str))))
+ org-latex-pdf-process))
+
+(setcar (cdr (cddaar tex-compile-commands)) " -shell-escape ")
+```
+
+## Python
+
+[Jedi](http://tkf.github.io/emacs-jedi/released/) offers very nice auto completion for `python-mode`. Mind that it is
+dependent on some python programs as well, so make sure you follow the
+instructions from the site.
+
+```lisp
+;; (setq jedi:server-command
+;; (cons "python3" (cdr jedi:server-command))
+;; python-shell-interpreter "python3")
+(add-hook 'python-mode-hook 'jedi:setup)
+(setq jedi:complete-on-dot t)
+(add-hook 'python-mode-hook 'jedi:ac-setup)
+```
+
+## Haskell
+
+`haskell-doc-mode` is similar to `eldoc`, it displays documentation in
+the echo area. Haskell has several indentation modes - I prefer using
+`haskell-indent`.
+
+```lisp
+(add-hook 'haskell-mode-hook 'turn-on-haskell-doc-mode)
+(add-hook 'haskell-mode-hook 'turn-on-haskell-indent)
+```
+
+## Matlab
+
+Matlab is very similar to Octave, which is supported by Emacs. We just
+need to let `.m`-files be associated with `octave-mode`.
+
+```lisp
+(add-to-list 'matlab-shell-command-switches "-nosplash")
+```
+
+
