Overview
========

Requirements
------------

Powerline requires Python 2.7 to work.

Vim plugin requirements
^^^^^^^^^^^^^^^^^^^^^^^

The vim plugin requires a vim version with Python 2.7 support compiled in.  
You can check if your vim supports Python 2 by running ``vim --version 
| grep +python``.

Vim version 7.3.661 or newer is recommended for performance reasons.

Installation
------------

Installing with ``pip``
^^^^^^^^^^^^^^^^^^^^^^^

To install Powerline system-wide, run the following command as root::

    pip install https://github.com/Lokaltog/powerline/tarball/develop

If you don't have root access or don't want to install Powerline 
system-wide, install with ``pip install --user`` instead.

.. note:: Make sure that you install the package for Python 2. For distros 
   like Arch Linux you'll have to run ``pip2`` instead of ``pip``.

Distribution-specific packages
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The following distribution-specific packages are officially supported, and 
they provide an easy way of installing and upgrading Powerline:

* `Arch Linux (AUR) <https://aur.archlinux.org/packages/powerline-git/>`_

Usage
-----

Vim usage
^^^^^^^^^

If Powerline is installed as a Python package, you can enable the vim plugin 
by adding the following line to your ``vimrc``::

    python from powerline.ext.vim import source_plugin; source_plugin()

If Powerline is installed somewhere other than Python's site-packages 
directories (e.g. by having the git repo in your dotfiles directory) you'll 
have to source the vim plugin file with an absolute path to the plugin 
location.

Add the following line to your ``vimrc``, where ``{path}`` is the path to 
the main Powerline project directory::

    source {path}/powerline/ext/vim/powerline.vim
