# 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]).
|
|
* despite the small size, it is fully featured and already integrates with: [vim-bufferline][f], [fugitive][d], [unite][i], [ctrlp][j], [minibufexpl][o], [gundo][p], [undotree][q], [nerdtree][r], [tagbar][s] 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'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][a]?
|
|
|
|
* 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!
|
|
|
|
# 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`
|
|
|
|
# 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][t]. Prepatched fonts can be found in the [powerine-fonts][c] repository.
|
|
|
|
Finally, enable them in vim-airline by adding `let g:airline_powerline_fonts = 1` to your vimrc.

# FAQ/Troubleshooting
|
|
|
|
* the powerline font symbols are not showing up
|
|
* the older deprecated [vim-powerline][a] uses different font codes; ensure you are using v2 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][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.
|
|
* how do i get rid of the default mode indicator?
|
|
* add `set noshowmode` to your vimrc

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.
