Lean & mean statusline for vim that's light as air.
2013-07-01 03:29:35 +08:00

# Rationale
2013-07-01 03:29:35 +08:00
2013-07-10 06:05:37 +08:00
There's already [powerline][b], why yet another statusline?
2013-07-01 03:29:35 +08:00
2013-07-06 08:15:52 +08:00
* it's 100% vimscript; no python needed.
2013-07-07 21:07:03 +08:00
* 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]).
2013-07-10 06:32:35 +08:00
* 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].
2013-07-06 08:15:52 +08:00
* it looks good with regular fonts, and provides configuration points so you can use unicode or powerline symbols.
2013-07-03 10:51:10 +08:00
* it's fast to load, taking roughly 1ms. by comparison, powerline needs 60ms on the same machine.
2013-07-06 08:15:52 +08:00
* it's fully customizable; if you know a little `statusline` syntax you can tweak it to your needs.
2013-07-10 06:32:35 +08:00
* 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!)
2013-07-01 03:29:35 +08:00
2013-07-10 06:05:37 +08:00
What about [old powerline][a]?
2013-07-03 21:40:58 +08:00
2013-07-06 08:15:52 +08:00
* the old version still works well, but since it's deprecated new features won't get added
2013-07-11 01:54:25 +08:00
* 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?
2013-07-01 03:29:35 +08:00
2013-07-10 06:05:37 +08:00
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][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
2013-07-01 03:29:35 +08:00
2013-07-07 02:01:32 +08:00
* the powerline font symbols are not showing up
2013-07-13 10:47:56 +08:00
* the older deprecated [vim-powerline][a] uses different font codes; ensure you are using v2 fonts.
2013-07-07 02:01:32 +08:00
* there is a pause when leaving insert mode
2013-07-02 08:35:16 +08:00

2013-07-08 08:38:19 +08:00
* you don't see any colors
2013-07-08 09:00:14 +08:00
* 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.
2013-07-07 02:01:32 +08:00
* you get the error `Unknown function: fugitive#head`
2013-07-02 23:44:59 +08:00

2013-07-07 02:01:32 +08:00
* airline doesn't appear until i create a new split
2013-07-06 08:15:52 +08:00

2013-07-07 02:01:32 +08:00
* 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
2013-07-09 22:03:35 +08:00
* the statusline wraps
* you are probably using iTerm with double-width characters enabled. either disable this, or `set ambiwidth=double` in your vimrc.
2013-07-10 06:32:35 +08:00
* how do i get rid of the default mode indicator?
