This page is a journal of my experiments with emacs. In November of 2008, I decided to use emacs for all my text editing purposes, after long been convinced of Emacs’s power and utility in editing programs and texts. At this time, I consider myself to be an adequate user of vim, emacs and TextMate. My goal is to teach myself emacs in an auto-didactic manner and make a note of the questions I had and the solutions I found for them. I hope this serves as a reminder for myself on a later date.
Note: All the instructions on this page, unless otherwise noted, are tested on Mac OS X systems and Aquamacs.

Here is a nice AppleScript created by Brian McCallister that provides proper emacsclient behaviour. Update: this script launches a “terminal” window, which is an annoyance.

Customizing emacs is done through editing
~/.emacs file. Though, if
you are using
emacs-starter-kit you will be putting files under
You can bind any operation that you can do in emacs to a set of key strokes. For example: the emacs-git integration – magit can be invoked by typing
M-x magit-status. But, this gets tiring after a while, so you may want to assign a short cut. Short cuts in Emacs start with ‘C-c’. You have to decide what comes after
C-c. In this case, I chose magit-status.
Add the following lines to your .emacs file:
;; C-c ms Magit-status (global-set-key (kbd "C-c ms") 'magit-status)
The first line is the comment (a good practice) and the second line tells emacs to call
magit-status when you press
Select the block of code that you want to reload and hit
C-x C-e (evaluate). This can also be achieved by positioning the cursor (point in emacs lingo) after the last closing parentheses of the function and typing
Install ConTEXt. Install AUCTEX using
port (on mac).
$ sudo port install auctex
Active AucTEX by putting this
(load "auctex.el" nil t t) in
Install YASnippet to get auto-completion on emacs. To use YASnippet, type in the trigger word and press TAB. For example, typing
def and pressing TAB will give you
def name(): """ """
The next tab press allows you replace the default function name with your own, with subsequent tabs taking you to the parameter list, docstring and finally the body of the function
This page has a nice collection of free programming fonts optimized for editing code over long durations of code. The rule of thumb to remember while selecting a programming font is: it should be a fixed width font. This is especially true in languages like “Python”:Python where indentation is essential in understanding the code flow.
I currently use Monaco, a font that is available on Mac OS X set to size 10.
Instead of editing the muse-latex.el and muse-book.el files, just use customize on the muse-latex-header and muse-book-latex-header variables. Upgrades to new versions of muse will be much smoother.
Main entry point
M-x magit-status (bound to C-c ms). Go to the magit
*magit: PRJNAME* and press tab on the line containing the
filenames. The modified text will expand underneath. Press
g in the magit buffer to refresh git status. or execute
M-x magit-status from one of the repository files.
The emacs manual
defines tells us that setting buffer variable
t will show trailing white spaces.
(setq show-trailing-whitespace 't)
Paste the above line into the current emacs buffer and evaluate the
statement by pressing
C-x C-e. Delete the white spaces with
emacs -q --eval '(condition-case err (progn (load "~/.emacs") (kill-emacs 0)) (error (kill-emacs 1)))'
emacsclient -n -e '(kill-emacs)'

Movie showing how to setup slime, swank, sbcl and emacs
check out slime and put it somewhere convenient, ie.,
Put the following lines in
(require :asdf) (push "/Users/pradeep/elisp/slime/" asdf:*central-registry*)
Load swank in sbcl:
$ sbcl (asdf:oos 'asdf:load-op :swank) (setf swank:*use-dedicated-output-stream* nil) (setf swank:*communication-style* :fd-handler) (swank:create-server :dont-close t)
What’s new in emacs 24?
git clone git://git.savannah.gnu.org/emacs.git cd emacs sudo apt-get install libxpm-dev sudo apt-get install libgif-dev sudo apt-get install libtiff-dev ./configure make sudo make install
My initial impression of
emacs24 is that it feels much faster compared
to the stock
emacs-snapshot available on
C-h i d m TOPIC RETto pull up info page on TOPIC. eg:
C-h i d m AUCTeX RETfor AUCTeX
Is it possible to show the keybindings in the modeline?
Use case: I have configured ‘Fn’ keys for mode specific actions, but do not remember them, or I want emacs to prompt me to use them.
