EdgeCase Emacs Config

You should give it a try.


This config is built primarily to work on top of the OS X version of Emacs. Be sure to download version 24 or greater.


  1. git clone git://
  2. cd emacs-config
  3. rake
  4. Open emacs with your app launcher of choice. You should see emacs downloading and compiling the defined packages.

We have leveraged Phil Hagelberg's emacs-starter-kit which uses Marmalade for downloading common emacs packages.


For a clojure development environment, follow the steps below.

  1. Install Leiningen

  2. If you're planning to use clojure-jack-in for opening SLIME in a clojure project, you must run $ lein plugin install swank-clojure <VERSION> where <VERSION> is the version of swank-clojure you wish to install. OR

  3. add swank-clojure to your project.clj :dev-dependencies and run lein deps. This will allow you to open a SLIME session inside the leiningen project.


Emacs works especially well when wanting user-specific configurations.

Simply place customization files to the folder ~/.emacs.d/<username>. Where <username> is the whoami or logname of the currently logged in user.

  • Any file with a .el extension in that folder will be loaded when running emacs.

We suggest creating your own repository of .el files and symlinking them to the folder ~/.emacs.d/<username>.

Dired Mode

Think of it as "directory edit" mode.

Dired Mode Resources

C-x d => dired mode

  • C-x C-q => edit filename inline
  • C-c C-c => commit changes
  • d => schedule file for deletion
  • u => unschedule action for this line
  • x => execute scheduled changes

Version Control

Using Magit

C-x v = => diff

C-x v u => undo local changes

C-x v l => view commit log

C-x v i => include in repository (git add <file>)

C-c g => MAGIT status

  • <tab> => view diff
  • s => stage changes
  • S => stage all changes
  • u => unstage changes
  • c => commit buffer
  • k => delete file
  • C-c C-c => commit changes
  • C-c C-a => amend changes
  • P => push buffer
  • F => pull
  • b => change branch
  • B => new branch
  • g => refresh status buffer
  • l => view git log


C-c C-j => clojure-jack-in

C-c f => find-file-in-project

C-c d => define function, creates new function for the current symbol video

M-x heroku-repl => open repl in a heroku-hosted clojure project

Clojure Test

Support for Clojure tests using clojure.test via SLIME and the buffer.

C-c ,, C-c C-, => run tests

C-c M-, => run current test

C-c ', C-c C-' => show test results

C-c k => clear test results

C-c t => jump to implementation

M-p => jump to previous problem

M-n => jump to next problem
