Installing powerline on Mac OSX. The following was done in version Version 10.8.2

Powerline.md

Install dependencies

brew install cmake
brew install python
sudo easy_install pip

Add powerline bin to your path. In your zshrc file (or the paths files sourced in zshrc) add the following line

PATH="/usr/local/share/python/:$PATH"

Reinstall MacVim with brew

I needed to edit the formula to specify which python to build against.

brew edit macvim

Edit it as follows (tip is from here)

Find the arguments list (begins with args = %W[ ...), and modify this line:

--enable-pythoninterp

Change it to these two lines:

--enable-pythoninterp=dynamic
--with-python-config-dir=/usr/local/lib/python2.7/config

On my system the above folder did not exist so I had to link it as follows

ln -s /usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/Current/lib/python2.7/config /usr/local/lib/python2.7/config

then reinstall it

brew remove macvim
brew install macvim --env-std --override-system-vim

Install powerline

pip install --user git+git://github.com/Lokaltog/powerline --verbose

Install fonts

Install the fonts by downloading them (https://github.com/Lokaltog/powerline-fonts/tree/master/Meslo), click on them, and then click install in the application that opens.

Usage

Add the following to your dot files

.vimrc

set rtp+=/usr/local/lib/python2.7/site-packages/powerline/bindings/vim

if has("gui_running")
   let s:uname = system("uname")
   if s:uname == "Darwin\n"
      set guifont=Meslo\ LG\ S\ for\ Powerline
   endif
endif

Note: Use your desired font in place of Meslo above. The first line is needed for all vim and the next few lines are needed for MacVim GUI.

.zshrc

. /usr/local/lib/python2.7/site-packages/powerline/bindings/zsh/powerline.zsh

.tmux.conf

source '/usr/local/lib/python2.7/site-packages/powerline/bindings/tmux/powerline.conf'

Installing iTerm from source

I needed to do this because my Fonts were not working. Without this it looked like ↓

• git clone https://github.com/gnachman/iTerm2
• start XCode
• open the iTerm.xcodeproj
• Click Run

It will build and launch iTerm. Then copy the app to /Applications. It will be something like:

mv /Users/wmernagh/Library/Developer/Xcode/DerivedData/iTerm-dmqofiayvqouzqakzaudepvpnfgb/Build/Products/Development/iTerm.app /Applications

Configure iTerm to use the powerline fonts

In Preferences > Profiles > Text and select the fonts:

Result

If all goes well it should look like this:

vim (MacVim launched as vi or vim in the iTerm2)

MacVim GUI

zsh

tmux
