add global variable g:airline#extensions#ctrlp#color_template which can hold modes normal|insert|visual|replace as string. ctrlp will use the given mode's colors if the active theme doesn't define any.

INTRODUCTION *airline*
|
||
|
||
vim-airline is a fast and lightweight alternative to powerline, written
|
||
in 100% vimscript with no outside dependencies.
|
||
|
||
==============================================================================
|
||
FEATURES *airline-features*
|
||
|
||
* tiny core written with extensibility in mind.
|
||
* integrates with many popular plugins.
|
||
* looks good with regular fonts, and provides configuration points so you
|
||
can use unicode or powerline symbols.
|
||
* optimized for speed; it loads in under a millisecond.
|
||
* fully customizable; if you know a little |statusline| syntax you can
|
||
tweak it to your needs.
|
||
* extremely easy to write themes.
|
||
|
||
==============================================================================
|
||
NAME *airline-name*
|
||
|
||
Where did the name come from?
|
||
|
||
I wrote this on an airplane, and since it's light as air it turned out to be a
|
||
good name :-)
|
||
|
||
==============================================================================
|
||
CONFIGURATION *airline-configuration*
|
||
|
||
There are a couple configuration values available (shown with their default
|
||

For more intricate customizations, you can replace the predefined sections
|
||
with the usual statusline syntax. Note that many of these settings can also be
|
||
controlled with |airline-configuration| variables, which is useful for
|
||
sections which by default host more than one extension.

FUNCREFS *airline-funcrefs*
|
||
|
||
vim-airline internally uses funcrefs to integrate with third party plugins,
|
||
and you can tap into this functionality to extend it for you needs.
|
||
|
||
*g:airline_statusline_funcrefs*
|
||
The g:airline_statusline_funcrefs variable is an array of funcrefs that get
|
||
invoked before the statusline gets overwritten for each window. The following
|
||
is an example of how you can extend vim-airline to support a new plugin.
|
||
>
|
||
function! MyPlugin()
|
||
if &filetype == 'MyPluginFileType'
|
||
let w:airline_section_a = 'MyPlugin'
|
||
let w:airline_section_b = '%f'
|
||
let w:airline_section_c = '%{MyPlugin#function()}'
|
||
let g:airline_variable_referenced_in_statusline = 'foo'
|
||
endif
|
||
endfunction
|
||
call add(g:airline_statusline_funcrefs, function('MyPlugin'))
|
||
<
|
||
*g:airline_exclude_funcrefs*
|
||
The g:airline_exclude_funcrefs variable is an array that's returns 1 or 0 to
|
||
determine whether that particular window should be excluded from having its
|
||
statusline modified. Here is an example:
|
||
>
|
||
function! ExcludeFoo()
|
||
return &filetype == 'FooType'
|
||
endfunction
|
||
call add(g:airline_exclude_funcrefs, function('ExcludeFoo'))
|
||
<
|
||
|
||
==============================================================================
|
||
WRITING EXTENSIONS *airline-writing-extensions*
|
||
|
||
The basic idea is that the statusline is rendered with a series of overrides.
|
||
For each section that the algorithm encounters, it will first check to see if
|
||
there is a window-local variable of the section. If it exists, the value will
|
||
be used, otherwise, the global variable of the section will be used. This
|
||
means it is possible to override only one or two sections of the statusline.
|
||
See |g:airline_statusline_funcrefs| for an example of a simple extension.
|
||
|
||
For contributions into the plugin, here are the following guidelines:
|
||
|
||
1. For simple |&filetype| checks, they can be added directly into the
|
||
`extensions.vim` file.
|
||
|
||
2. Pretty much everything else should live as a separate file under the
|
||
`extensions/` directory.
|
||
|
||
a. Inside `extensions.vim`, add a check for some variable or command that
|
||
is always available (these must be defined in `plugin`, and _not_
|
||
`autoload` of the other plugin). If it exists, then initialize the
|
||
extension. This ensures that the extension is loaded if and only if the
|
||
user has the other plugin installed.
|
||
|
||
b. Extension specific variables should be defined in the extension, e.g.
|
||
`g:airline#extensions#foo_plugin#bar_variable`. Unfortunately, the
|
||
branch extension does not follow this convention, but for legacy reasons
|
||
those variables are kept as is.
|
||
|
||
See the source of |example.vim| for a working extension.
|
||
|
||
==============================================================================
|
||
WRITING THEMES *airline-themes*
|
||
|
||
Themes are written "close to the metal" -- you will need to know some basic
|
||
VimL syntax to write a theme, but if you've written in any programming
|
||
language before it will be easy to pick up.
|
||
|
||
The |dark.vim| theme fully documents this procedure and will guide you through
|
||
the process. The |jellybeans.vim| theme is another example of how to write a
|
||
theme, but instead of manually declaring colors, it extracts the values from
|
||
highlight groups.
|
||
|
||
==============================================================================
|
||
TROUBLESHOOTING *airline-troubleshooting*
|
||
|
||
Q. There are no colors.
|
||
A. You need to set up your terminal correctly. For more details, see
|
||
<http://vim.wikia.com/wiki/256_colors_in_vim>. Alternatively, if you want
|
||
to bypass the automatic detection of terminal colors, you can force Vim
|
||
into 256 color mode with this: >
|
||
set t_Co=256
|
||
<
|
||
Q. The statusline does not appear until I create a split.
|
||
A. This is the default setting of |laststatus|. If you want it to appear all
|
||
the time, add the following to your vimrc: >
|
||
set laststatus=2
|
||
<
|
||
Q. Powerline symbols are not showing up.
|
||
A. First, you must install patched powerline fonts. Second, you must enable
|
||
unicode in vim. >
|
||
set encoding=utf-8
|
||
<
|
||
Q. There is a pause when leaving insert mode.
|
||
A. Add the following to your vimrc. >
|
||
set ttimeoutlen=50
|
||
<
|
||
Q. The colors look a little off for some themes.
|
||
A. Certain themes are derived from the active colorscheme by extracting colors
|
||
from predefined highlight groups. These airline themes will look good for
|
||
their intended matching colorschemes, but will be hit or miss when loaded
|
||
with other colorschemes.
|
||
|
||
