dotfiles.git

Clone and run this on a new EC2 instance running Ubuntu 12.04.2 LTS to configure your bash and emacs development environment as follows:

cd $HOME
git clone https://github.com/startup-class/dotfiles.git
ln -sb dotfiles/.screenrc .
ln -sb dotfiles/.bash_profile .
ln -sb dotfiles/.bashrc .
ln -sb dotfiles/.bashrc_custom .
mv .emacs.d .emacs.d~
ln -s dotfiles/.emacs.d .

See also http://github.com/startup-class/setup to install prerequisite programs. If all goes well, in addition to a more useful prompt, now you can do emacs -nw hello.js and hitting C-c! to launch an interactive SSJS REPL, among many other features. See the Startup Engineering Video Lectures 4a/4b for more details.

Addition for vim (per http://vim.wikia.com/wiki/Indenting_source_code ):

First enable file type detection with the following in your vimrc:

filetype plugin indent on

Create file html.vim with contents:

setlocal shiftwidth=2
setlocal tabstop=2

The html.vim file should be in this directory (which you may need to create): ~/.vim/after/ftplugin
