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 and syntastic.
- 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.)
Why's it called airline?
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!

FAQ/Troubleshooting
- the powerline font symbols are not showing up
- enable them by adding
let g:airline_powerline_fonts=1
to your vimrc. - the older deprecated vim-powerline uses different font codes compared to the newer powerline. you can grab prepatched fonts at powerline-fonts.
- there is a pause when leaving insert mode
- you need to set
ttimeoutlen
to a low number; 50 is recommended - you don't see any colors
- all of the themes use a 256 terminal color palette. it's likely that the value of
t_Co
is misconfigured. please see this article on how to configure your terminal. pull requests for 8 and 16 color terminals are welcome. - you get the error
Unknown function: fugitive#head
- you are probably using version 1.2, which is very old...download v2 from the project page.
- airline doesn't appear until i create a new split
- add
set laststatus=2
to your vimrc - bufferline is printing to the statusline as well as the command bar
- you can disable automatic echoing by adding
let g:bufferline_echo = 0
to your vimrc - the statusline wraps
- you are probably using iTerm with double-width characters enabled. either disable this, or
set ambiwidth=double
in your vimrc. - how do i get rid of the default mode indicator?
- add
set noshowmode
to your vimrc

). - a link to a gist or your vimrc where it can be reproduced.
