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")))
(require 'cl-lib)

Package Management
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.
(add-to-list 'package-archives
'("melpa" . "http://melpa.org/packages/"))
(add-to-list 'package-archives
'("org" . "http://orgmode.org/elpa/"))
;; install any packages in burd-packages, if they are not installed already
(let ((refreshed nil))
(when (not package-archive-contents)
(package-refresh-contents)
(setq refreshed t))
(dolist (pkg burd-packages)
(when (and (not (package-installed-p pkg))
(assoc pkg package-archive-contents))
(unless refreshed
(package-refresh-contents)
(setq refreshed t))
(package-install pkg))))
(defun package-list-unaccounted-packages ()
"Like `package-list-packages', but shows only the packages that
are installed and are not in `burd-packages'. Useful for
cleaning out unwanted packages."
(interactive)
(package-show-package-list
(remove-if-not (lambda (x) (and (not (memq x burd-packages))
(not (package-built-in-p x))
(package-installed-p x)))
(mapcar 'car package-archive-contents))))
Start-up options
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.
(delete-selection-mode t)
(transient-mark-mode t)
(setq x-select-enable-clipboard t)
Display Settings
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.
(when window-system
(setq frame-title-format '(buffer-file-name "%f" ("%b")))
(set-face-attribute 'default nil
:family "Fira Code"
:height 134
:weight 'normal
:width 'normal)

Font Ligature
Modern fonts such as Fira Code and PragmataPro provide ligatures for common useful programming constructs (for example -> to ⟶ or lambda to λ). https://github.com/tonsky/FiraCode/wiki/Emacs-instructions https://emacs.stackexchange.com/questions/9586/otf-ligature-support-in-emacs https://www.reddit.com/r/emacs/comments/4sm6fa/how_to_enable_pragmatapro_ligatures/

Indentation
There's nothing I dislike more than tabs in my files. Make sure I don't share that discomfort with others.
(setq tab-width 4
indent-tabs-mode nil)
Backup files
Some people like to have them. I don't. Rather than pushing them to a folder, never to be used, just turn the whole thing off.
(setq make-backup-files nil)
Yes and No
Nobody likes to have to type out the full yes or no when Emacs asks. Which it does often. Make it one character.
(defalias 'yes-or-no-p 'y-or-n-p)
Key bindings
Miscellaneous key binding stuff that doesn't fit anywhere else.
(global-set-key (kbd "RET") 'newline-and-indent)
(global-set-key (kbd "C-;") 'comment-or-uncomment-region)
(global-set-key (kbd "M-/") 'hippie-expand)

(global-set-key (kbd "C-x g") 'magit-status)
(if (eq system-type 'darwin)
(progn
(setq mac-option-modifier 'meta)))
Misc
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.
(setq echo-keystrokes 0.1
use-dialog-box nil
visible-bell t)
(show-paren-mode t)
(setq magit-auto-revert-mode nil)
(setq magit-last-seen-setup-instructions "1.4.0")
Vendor directory
I have a couple of things that don't come from package managers. This includes the directory for use.
(defvar burd/vendor-dir (expand-file-name "vendor" user-emacs-directory))
(add-to-list 'load-path burd/vendor-dir)
(dolist (project (directory-files burd/vendor-dir t "\\w+"))
(when (file-directory-p project)
(add-to-list 'load-path project)))
Org
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.
;; (require 'org)
;; (require 'org-loaddefs)
;; (require 'org-habit)
;; (add-to-list 'org-modules "org-habit")
;; (setq org-habit-preceding-days 7
;; org-habit-following-days 1
;; org-habit-graph-column 80
;; org-habit-show-habits-only-for-today t
;; org-habit-show-all-today t)
org-babel
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.
(require 'ob)
(org-babel-do-load-languages
'org-babel-load-languages
'((shell . t)
(ditaa . t)
(plantuml . t)

Utilities
ditaa
There's no substitute for real drawings, but it's nice to be able
to sketch things out and produce a picture right from
org-mode
. This sets up ditaa
for execution from inside a babel
block.
(setq org-ditaa-jar-path "~/.emacs.d/vendor/ditaa0_9.jar")
plantuml
(setq org-plantuml-jar-path "~/.emacs.d/vendor/plantuml.jar")
deft
deft
provides random note taking with history and
searching. Since I use org-mode
for everything else, I turn that
on as the default mode for deft
and put the files in Dropbox.
(setq deft-directory "~/Dropbox/deft")
(setq deft-use-filename-as-title t)
(setq deft-extension "org")
(setq deft-text-mode 'org-mode)
Smex
smex
is a necessity. It provides history and searching on top of M-x
.
(setq smex-save-file (expand-file-name ".smex-items" user-emacs-directory))
(smex-initialize)
(global-set-key (kbd "M-x") 'smex)
(global-set-key (kbd "M-X") 'smex-major-mode-commands)
Ido
Ido
mode provides a nice way to navigate the filesystem. This is
mostly just turning it on.
(ido-mode t)
(setq ido-enable-flex-matching t
ido-use-virtual-buffers t)
Column number mode
Turn on column numbers.
(setq column-number-mode t)
Temporary file management
Deal with temporary files. I don't care about them and this makes them go away.
(setq backup-directory-alist `((".*" . ,temporary-file-directory)))
(setq auto-save-file-name-transforms `((".*" ,temporary-file-directory t)))
autopair-mode
This makes sure that brace structures (), [], {}
, etc. are closed
as soon as the opening character is typed.
; (require 'autopair)
Power lisp
A bunch of tweaks for programming in LISP dialects. It defines the
modes that I want to apply these hooks to. To add more just add
them to lisp-modes
. This also creates its own minor mode to
properly capture the behavior. It remaps some keys to make paredit
work a little easier as well. It also sets clisp
as the default
lisp program and racket
as the default scheme program.
(setq lisp-modes '(lisp-mode
emacs-lisp-mode
common-lisp-mode
scheme-mode
clojure-mode))
(defvar lisp-power-map (make-keymap))
(define-minor-mode lisp-power-mode "Fix keybindings; add power."
:lighter " (power)"
:keymap lisp-power-map
(paredit-mode t))
(define-key lisp-power-map [delete] 'paredit-forward-delete)
(define-key lisp-power-map [backspace] 'paredit-backward-delete)
(cl-defun burd/engage-lisp-power ()
(lisp-power-mode t))
(dolist (mode lisp-modes)
(add-hook (intern (format "%s-hook" mode))
#'burd/engage-lisp-power))
(setq inferior-lisp-program "clisp")
(setq scheme-program-name "racket")
auto-complete
Turn on auto complete.
; (require 'auto-complete-config)
; (ac-config-default)
Indentation and buffer cleanup
This re-indents, untabifies, and cleans up whitespace. It is stolen directly from the emacs-starter-kit.
(cl-defun untabify-buffer ()
(interactive)
(untabify (point-min) (point-max)))
(cl-defun indent-buffer ()
(interactive)
(indent-region (point-min) (point-max)))
(cl-defun cleanup-buffer ()
"Perform a bunch of operations on the whitespace content of a buffer."
(interactive)
(indent-buffer)
(untabify-buffer)
(delete-trailing-whitespace))
(cl-defun cleanup-region (beg end)
"Remove tmux artifacts from region."
(interactive "r")
(dolist (re '("\\\\│\·*\n" "\W*│\·*"))
(replace-regexp re "" nil beg end)))
(global-set-key (kbd "C-x M-t") 'cleanup-region)
(global-set-key (kbd "C-c n") 'cleanup-buffer)
(setq-default show-trailing-whitespace t)
flyspell
The built-in Emacs spell checker. Turn off the welcome flag because it is annoying and breaks on quite a few systems. Specify the location of the spell check program so it loads properly.
(setq flyspell-issue-welcome-flag nil)
(if (eq system-type 'darwin)
(setq-default ispell-program-name "/usr/local/bin/aspell")
(setq-default ispell-program-name "/usr/bin/aspell"))
(setq-default ispell-list-command "list")
multi-web-mode
When editing HTML it's a jumble of languages embedded into a single file. Emacs can choose the major-mode based on the section of the file if you enable it.
(require 'multi-web-mode)
(setq mweb-default-major-mode 'html-mode)
(setq mweb-tags
'((php-mode "<\\?php\\|<\\? \\|<\\?=" "\\?>")
(js-mode "<script[^>]*>" "</script>")
(css-mode "<style[^>]*>" "</style>")))
(setq mweb-filename-extensions '("php" "htm" "html" "ctp" "phtml" "php4" "php5"))

CoffeeScript Mode
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.

Enable Markdown mode and setup additional file extensions. Use pandoc to generate HTML previews from within the mode, and use a custom css file to make it a little prettier.
