A reasonable Emacs config
This is my emacs configuration tree, continually used and tweaked since 2000, and it may be a good starting point for other Emacs users, especially those who are web developers. These days it's somewhat geared towards OS X, but it is known to also work on Linux and Windows.
Emacs itself comes with support for many programming languages. This config adds improved defaults and extended support for the following:
- Ruby / Ruby on Rails
- CSS / LESS / SASS / SCSS
- HAML / Markdown / Textile / ERB
- Clojure (with Cider and nRepl)
- Common Lisp (with Slime)
Supported Emacs versions
The config should run on Emacs 23.3 or greater and is designed to
degrade smoothly - see the Travis build - but note that Emacs 24 and
above is required for an increasing number of key packages, including
flycheck, so to get full you should use the
latest Emacs version available to you.
Some Windows users might need to follow these instructions to get TLS (ie. SSL) support included in their Emacs.
To make the most of the programming language-specific support in this config, further programs will likely be required, particularly those that flycheck uses to provide on-the-fly syntax checking.
To install, clone this repo to
~/.emacs.d, i.e. ensure that the
init.el contained in this repo ends up at
git clone https://github.com/jdknoll/emacs.d.git
Upon starting up Emacs for the first time, further third-party
packages will be automatically downloaded and installed. If you
encounter any errors at that stage, try restarting Emacs, and possibly
M-x package-refresh-contents before doing so.
Important note about
This config enables
ido-mode completion in the minibuffer wherever
possible, which might confuse you when trying to open files using
C-x C-f, e.g. when you want to open a directory to use
dired -- if you get stuck, use C-f to drop into the
find-file prompt. (You might want to customize the
ido-show-dot-for-dired variable if this is an issue for you.)
Update the config with
git pull. You'll probably also want/need to update
the third-party packages regularly too:
M-x package-list-packages, then U followed by x.
You should usually restart Emacs after pulling changes or updating
packages so that they can take effect. Emacs should usually restore
your working buffers when you restart due to this configuration's use
Adding your own customization
To add you own customization, use M-x customize and/or
create your own init files
~/.emacs.d/lisp/init-custom.el which looks like this:
... your code here ... (provide 'init-custom)
If you need initialisation code which executes earlier in the startup process,
you can also create an
If you plan to customize things more extensively, you should probably just fork the repo and hack away at the config to make it your own!

The process of making purcell's emacs.d is still in progress. The eventual goal is to
be able to remove any of the
(require init-file) lines without breaking the startup
in order to allow emacs users to add functionality as they need it.
This may be a long process as purcell's init.el contained references to 59 files.
As you add modules, you may find that starting emacs can take a while. You can benchmark
your init with Profile Dot Emacs. In order
to profile the startup file, you will need to change
Support / issues
If you hit any problems, please first ensure that you are using the latest version of this code, and that you have updated your packages to the most recent available versions (see "Updates" above). If you still experience problems, go ahead and file an issue on the github project.
