Setting Up Emacs for Development
May 04, 2014
Here is a guide that would help you to setup emacs.
First of all, If you are on Mac install emacs for OSX from here. you could easily install the GUI version of Emacs for other platforms too.
My Emacs config
This is my Emacs config which could be used for development in following technologies:
- Ruby / Ruby on Rails
- CSS / LESS / SASS / SCSS
- HAML / Markdown / Textile / ERB
- Clojure (via nrepl)
- Common Lisp (with Slime)
This is my emacs live in action:
- Emacs 23 or greater (note that Emacs 24 is required for some functionality, and will likely become the minimum required version some time soon.)
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/vinitkumar/.emacs.d.git ~/.emacs.d
Upon starting up Emacs for the first time, further third-party packages will be automatically downloaded and installed.
Adding your own customization
To add your own customization, use M-x customize and/or
create a file
~/.emacs.d/lisp/init-local.el which looks like this:
... your code here ... (provide 'init-local)
Tips for using these emacs settings
If you want to use my settings straight out of the box, here are some things to note:
- I recommend starting with a blank emacs + Technomancy’s better-defaults package, and then dig through this repo for useful nuggets, instead of forking it directly.
- The key bindings are optimized for a norwegian keyboard layout.
- Start by reading up on all the cool stuff in key-bindings.el.
- You quit emacs with
C-x r q, mnemonic Really Quit.
- Find file in project with
C-x o, in dir with
C-x C-f, recent with
- Add your user- and project-specific stuff in .emacs.d/users/[machine name]/*.el
C-his rebound to backspace, like in the shell. Get help on
- Autocomplete with
C-.(autocomplete entire lines with
- expand-region is your friend. Find its bound key by doing
F1 f er/expand-region
- Undo with
C-_and redo with
M-_. Watch the undo-tree with
- Quickly jump anywhere in the buffer with
C-øthen the starting letter of a word.
- Indent and clean up white space in the entire buffer with
- On a mac, the Meta key
Mis bound to Command.
- I recommend rebinding Caps Lock to Ctrl and use that instead of the often badly placed Ctrl-key.
