Gregory Burd's Emacs 24 Configuration
- Configuration
Configuration
Emacs is a special beast. Taming it takes a lot of care. In an attempt to document/explain/share with the rest of the world, this is my attempt at configuration as a literate program. It also shows off the awesome power of org-mode, which makes all of this possible.
User details
Emacs will normally pick this up automatically, but this way I can be sure the right information is always present.
(setq user-full-name "Gregory Burd")
(setq user-mail-address "greg@burd.me")Environment
There are plenty of things installed outside of the default
PATH. This allows me to establish additional PATH information. At
the moment, the only things that added are /usr/local/bin for
homebrew on OS X and .cabal/bin for Haskell package binaries.
Emacs lisp is really only a subset of common lisp, and I need to have some of the additional functionality to make the configuration and its dependencies work properly, which we get by requiring Common Lisp for Emacs.
;(setq debug-on-error t)
;(setq debug-on-signal t)
(setenv "PATH" (concat "/usr/local/bin:/opt/local/bin:/usr/bin:/bin" (getenv "PATH")))

This is the list of packages used in this configuration.

Since Emacs 24, Emacs includes the Emacs Lisp Package Archive (ELPA) by default. This provides a nice way to install additional packages. Since the default package archive doesn't include everything necessary, the marmalade, and melpa repositories are also added.

'("melpa" . "http://melpa.org/packages/"))
(add-to-list 'package-archives

Splash Screen
I want to skip straight to the scratch buffer. This turns off the
splash screen and puts me straight into the scratch buffer. I
don't really care to have anything in there either, so turn off
the message while we're at it. Since I end up using org-mode
most of the time, set the default mode accordingly.
(setq inhibit-splash-screen t
initial-scratch-message nil
initial-major-mode 'org-mode)Marking text
There are some behaviors in Emacs that aren't intuitive. Since I pair with others that don't know how Emacs handles highlighting, treat regions like other text editors. This means typing when the mark is active will write over the marked region. Also, make the common highlighting keystrokes work the way most people expect them to. This saves a lot of time explaining how to highlight areas of text. Emacs also has it's own clipboard and doesn't respond to the system clipboard by default, so tell Emacs that we're all friends and can get along.

I have some modifications to the default display. First, a minor tweak to the frame title. It's also nice to be able to see when a file actually ends. This will put empty line markers into the left hand side.

Turn down the time to echo keystrokes so I don't have to wait around for things to happen. Dialog boxes are also a bit annoying, so just have Emacs use the echo area for everything. Beeping is for robots, and I am not a robot. Use a visual indicator instead of making horrible noises. Oh, and always highlight parentheses. A person could go insane without that. Finally, Magit's behaviour changed, let's ack that change and prevent an potentially bad outcome.

org-mode is one of the most powerful and amazing features of
Emacs. I mostly use it for task/day organization and generating
code snippets in HTML. Just a few tweaks here to make the
experience better.
Settings
Enable logging when tasks are complete. This puts a time-stamp on
the completed task. Since I usually am doing quite a few things at
once, I added the INPROGRESS keyword and made the color
blue. Finally, enable flyspell-mode and writegood-mode when
org-mode is active.
(setq org-log-done t
org-todo-keywords '((sequence "TODO" "INPROGRESS" "DONE"))
org-todo-keyword-faces '(("INPROGRESS" . (:foreground "blue" :weight bold))))
(add-hook 'org-mode-hook
(lambda ()
(flyspell-mode)))
(add-hook 'org-mode-hook
(lambda ()
(writegood-mode)))org-agenda
First, create the global binding for org-agenda. This allows it
to be quickly accessed. The agenda view requires that org files be
added to it. The personal.org and groupon.org files are my
daily files for review. I have a habit to plan the next day. I do
this by assessing my calendar and my list of todo items. If a todo
item is already scheduled or has a deadline, don't show it in the
global todo list.
(global-set-key (kbd "C-c a") 'org-agenda)
(setq org-agenda-show-log t
org-agenda-todo-ignore-scheduled t
org-agenda-todo-ignore-deadlines t)
(setq org-agenda-files (list "~/Dropbox/org/personal.org"
"~/Dropbox/org/agenda.org"))org-habit
I have severial habits that I also track. In order to take full
advantage of this feature org-habit has to be required and added
to org-modules. A few settings are also tweaked for habit mode to
make the tracking a little more palatable. The most significant of
these is org-habit-graph-column. This specifies where the graph
should start. The default is too low and cuts off a lot, so I start
it at 80 characters.

org-babel is a feature inside of org-mode that makes this
document possible. It allows for embedding languages inside of an
org-mode document with all the proper font-locking. It also
allows you to extract and execute code. It isn't aware of
Clojure by default, so the following sets that up.

The default CoffeeScript mode makes terrible choices. This turns everything into 2 space indentations and makes it so the mode functions rather than causing you indentation errors every time you modify a file.
