These are my dotfiles that I use. They are setup primarily around Terminal Vim, ITerm2, and Tmux.

There is a little bit of specific initial setup to get things working smoothly.

• Make sure you have the latest vim, tmux, and iterm2

brew install --HEAD https://raw.github.com/adamv/homebrew-alt/master/duplicates/vim.rb
brew install tmux
brew install reattach-to-user-namespace

I installed the solarized colorscheme. Vim and tmux have the corresponding color schemes setup as well.

• Download it here: http://ethanschoonover.com/solarized
• I configured two seperate profiles. One for light and one for dark. I often switch between them based on day or night to combat glare. Tmux makes it very easy to switch without losing a beat. ** CMD-O, select new profile. Then run tmux attach and you are good to go. Vim is also configured with a shortcut to switch between light and dark themes
• Make sure you setup the profile to 'Report Terminal Type: xterm-256color' under "Profiles" / "Terminal". This helps address vim color issues in terminal.

A lot of this setup is summarized nicely and stolen from here: http://rhnh.net/2011/08/20/vim-and-tmux-on-osx
