vim-airline

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

Rationale

There's already powerline, why yet another statusline?

it's 100% vimscript; no python needed.
it's small. i want the core plugin to be less than 200 lines as a rule (specifically adhering to the open/closed principle).
despite the small size, it is fully featured and already integrates with: vim-bufferline, fugitive, unite, ctrlp, minibufexpl, gundo, undotree, nerdtree, tagbar, syntastic and lawrencium.
it looks good with regular fonts, and provides configuration points so you can use unicode or powerline symbols.
it's fast to load, taking roughly 1ms. by comparison, powerline needs 60ms on the same machine.
it's fully customizable; if you know a little statusline syntax you can tweak it to your needs.
it's trivial to write colorschemes; for a minimal theme you need to edit 9 lines of colors. (please send pull requests if you create new themes!)

What about old powerline?

the old version still works well, but since it's deprecated new features won't get added
it uses different font codes, which makes it incompatible with other powerline bindings in the same terminal (e.g. bash, zsh, tmux, etc.)

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!

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.
