My dotfiles include configs for vim, tmux, bash and zsh. They are good for setting up Mac OS X as a development system, but work on Linux too. Here's a (non-exhaustive) list of features:

• Consistent color scheme across bash, zsh, vim etc. (custom Monokai, with alternate themes if you want them)
• Sane vim config with modern, sensible settings
• Syntax checking right inside vim with Syntastic
• Fuzzy finding in vim with ctrlp
• bash & zsh prompt with git branch and time since last commit (thanks to grb)
• zsh wunjo support with detailed git information and assorted prompt customisations.
• powerline/airline in vim and tmux
• vim autocomplete using YouCompleteMe
• vim support for lots of things (Mustache, CoffeeScript, HAML, Jade, Markdown, Mocha, rspec, Stylus, Clojure, Processing)
• Improvements to make everything work properly in Mac OS X (e.g. clipboard in vim inside tmux)
• z.sh to jump around directories in bash
• Logging all bash commands to ~/.logs

Make sure you have backed up your existing files! Then, run this to clone everything into your home directory.

cd && git clone https://github.com/vladh/dotfiles --recursive
cd dotfiles
mv -i * .[^.]* ../
cd && rmdir dotfiles

For tmux to work properly on Mac OS X, you also need to install this:

brew install reattach-to-user-namespace

This makes tmux open new windows in the right directory. On Mac OS, tmux may not start using the given .tmux.conf if reattach-to-user-namespace is not installed.

You also need to install YouCompleteMe if you want vim completion. The instructions are here, but it generally goes something like:

cd ~/.vim/bundle/YouCompleteMe
./install.sh

To add any options you don't want to accidentally commit to the repo, like your git.config email or .bash_profile paths, make _private files. These will be included in your configuration but ignored by the repo. Currently supported:

• .bash_profile_private
• .vimrc_private
• .tmux.conf_private
• .gitconfig_private
• .zshrc_private

• The contributors
• Gary Bernhardt
• Steve Losh

Libraries used are difficult to list as they often change, but they are evident from the git submodules.
