# vim-airline
lean & mean statusline for vim that's light as air
# rationale
there's already [powerline][b], 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][h]).
* it gets you 90% of the way there; in addition to all the standard goodies, it integrates with [vim-bufferline][f], [fugitive][d], [unite][i], [ctrlp][j] and [syntastic][e].
* 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 is 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][a]?
* the old version still works well, but since it's deprecated new features won't get added
# 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!
# installation
this plugin follows the standard runtime path structure, and as such it can be installed with a variety of plugin managers:
* [pathogen][k]
* `git clone https://github.com/bling/vim-airline ~/.vim/bundle/vim-airline`
* [neobundle][l]
* `NeoBundle 'bling/vim-airline'`
* [vundle][m]
* `Bundle 'bling/vim-airline'`
* manual
* copy all of the files into your `~/.vim` directory
# configuration
`:help airline`
# 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][a] uses different codes compared to the newer [powerline][b].
* you can grab prepatched fonts at [powerline-fonts][c], or you can manually set the relevant `g:` variables
* 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][n] 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][d].
* 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.
# bugs
if you encounter a bug, please reproduce it with this [minivimrc][g] repository i created and file an issue. please provide your operating system and vim version/patch level (can be found with `:version`). a reproducible gist would be hugely helpful.

# 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.
* this plugin got a lot more popular than i initially expected, if you make changes to the core, please test on as many versions of vim as possible.
