Lean & mean statusline for vim that's light as air.

Features

tiny core (under 200 lines), written with extensibility in mind (specifically adhering to the open/closed principle).
integrates with a variety of plugins, including: vim-bufferline, fugitive, unite, ctrlp, minibufexpl, gundo, undotree, nerdtree, tagbar, syntastic and lawrencium.
looks good with regular fonts and provides configuration points so you can use unicode or powerline symbols.
optimized for speed; it loads in under a millisecond.
fully customizable; if you know a little statusline syntax you can tweak it to your needs.
extensive suite of themes for popular colorschemes including solarized (dark and light), tomorrow (all variants), molokai, jellybeans and others; have a look at the screenshots in the wiki.
supports 7.2 as the minimum Vim version

Rationale

There's already powerline, why yet another statusline?

100% vimscript; no python needed.

What about vim-powerline?

the author has been active developing powerline, which was rewritten in python and expands its capabilities to tools outside of Vim, such as bash, zsh, and tmux.
vim-powerline has been deprecated as a result, and no features will be added to it.
vim-powerline uses different font codes, so if you want to use it with a powerline themed tmux (for example), it will not work.

Where did the name come from?

I wrote the initial version on an airplane, and since it's light as air it turned out to be a good name. Thanks for flying vim!

Installation

This plugin follows the standard runtime path structure, and as such it can be installed with a variety of plugin managers:

Pathogen
git clone https://github.com/bling/vim-airline ~/.vim/bundle/vim-airline
NeoBundle
NeoBundle 'bling/vim-airline'
Vundle
Bundle 'bling/vim-airline'
VAM
call vam#ActivateAddons([ 'vim-airline' ])
manual
copy all of the files into your ~/.vim directory

Configuration

:help airline

Integrating with powerline fonts

For the nice looking powerline symbols to appear, you will need to install a patched font. Instructions can be found in the official powerline documentation. Prepatched fonts can be found in the powerline-fonts repository.

Finally, enable them in vim-airline by adding let g:airline_powerline_fonts = 1 to your vimrc.

reproduce it with this minivimrc repository to rule out any configuration conflicts.
a link to your vimrc or a gist which shows how you configured the plugin(s).
and so I can reproduce; your :version of vim, and the commit of vim-airline you're using.

Contributions

Contributions and pull requests are welcome. Please take note of the following guidelines:

adhere to the existing style as much as possible; notably, 2 space indents and long-form keywords.
keep the history clean! squash your branches before you submit a pull request. pull --rebase is your friend.
any changes to the core should be tested against Vim 7.2.
if you submit a theme, please create a screenshot so it can be added to the Wiki.
