# vim-airline

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][8]).
*  integrates with a variety of plugins, including: [vim-bufferline][6], [fugitive][4], [unite][9], [ctrlp][10], [minibufexpl][15], [gundo][16], [undotree][17], [nerdtree][18], [tagbar][19], [syntastic][5] and [lawrencium][21].
*  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][23] (dark and light), [tomorrow][24] (all variants), [molokai][25], [jellybeans][26] and others; have a look at the [screenshots][14] in the wiki.
*  supports 7.2 as the minimum Vim version

# Rationale

There's already [powerline][2], why yet another statusline?

*  100% vimscript; no python needed.

What about [vim-powerline][1]?

*  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][11]
  *  `git clone https://github.com/bling/vim-airline ~/.vim/bundle/vim-airline`
*  [NeoBundle][12]
  *  `NeoBundle 'bling/vim-airline'`
*  [Vundle][13]
  *  `Bundle 'bling/vim-airline'`
*  [VAM][22]
  *  `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][20].  Prepatched fonts can be found in the [powerline-fonts][3] repository.

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

# FAQ

# Themes/Screenshots

A full list of screenshots can be found in the [Wiki][14].

# Bugs

Tracking down bugs can take a very long time due to different configurations, versions, and operating systems.  To ensure a timely response, please help me out by doing the following:

*  reproduce it with this [minivimrc][7] 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][14].
