INTRODUCTION *airline-intro*
vim-airline is a fast and lightweight alternative to powerline, written
in 100% vimscript with no outside dependencies.
When the plugin is correctly loaded, Vim will draw a nice statusline at the
bottom of each window.
That line consists of several sections, each one displaying some piece of
information. By default (without configuration) this line will look like
this: >
+---------------------------------------------------------------------------+
|~ |
|~ |
|~ VIM - Vi IMproved |
|~ |
|~ version 8.0 |
|~ by Bram Moolenaar et al. |
|~ Vim is open source and freely distributable |
|~ |
|~ type :h :q<Enter> to exit |
|~ type :help<Enter> or <F1> for on-line help |
|~ type :help version8<Enter> for version info |
|~ |
|~ |
+---------------------------------------------------------------------------+
| A | B | C X | Y | Z | [...] |
+---------------------------------------------------------------------------+
The statusline is the colored line at the bottom, which contains the sections
(possibly in different colors):
section meaning (example)~
--------------------------
A displays mode + additional flags like crypt/spell/paste (`INSERT`)
B VCS information (branch, hunk summary) (`master`)
C filename + read-only flag (`~/.vim/vimrc RO`)
X filetype (`vim`)
Y file encoding[fileformat] (`utf-8[unix]`)
optionally may contain Byte Order Mark `[BOM]` and missing end of last
line `[!EOL]`
Z current position in the file
percentage % ln: current line/number of lines ☰ cn: column
So this: 10% ln:10/100☰ cn:20
means: >
10% - 10 percent
ln: - line number is
10/100☰ - 10 of 100 total lines
cn: - column number is
20 - 20
<
[...] additional sections (warning/errors/statistics)
from external plugins (e.g. YCM/syntastic/...)
For a better look, those sections can be colored differently, depending on
the mode and whether the current file is 'modified'
Additionally, several extensions exists, that can provide additional feature
(for example the tabline extension provides an extra statusline on the top of
the Vim window and can display loaded buffers and tabs in the current Vim
session).
Most of this is customizable and the default sections can be configured using
the vim variables g:airline_section_<name> (see |airline-default-sections|)
=============================================================================
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
values):
* enable experimental features >
" Currently: Enable Vim9 Script implementation
let g:airline_experimental = 1
* the separator used on the left side >
let g:airline_left_sep='>'
<
* the separator used on the right side >

let g:airline_detect_paste=1
<
* enable crypt detection >
let g:airline_detect_crypt=1
* enable spell detection >
let g:airline_detect_spell=1
* display spelling language when spell detection is enabled
(if enough space is available) >
let g:airline_detect_spelllang=1
<
* enable iminsert detection >
let g:airline_detect_iminsert=0
<

to only the filename of that buffer. >
let g:airline_inactive_collapse=1
<

let g:airline_inactive_alt_sep=1
<
* themes are automatically selected based on the matching colorscheme. this
can be overridden by defining a value. >
let g:airline_theme='dark'
<
Note: Only the dark theme is distributed with vim-airline. For more themes,
checkout the vim-airline-themes repository
(github.com/vim-airline/vim-airline-themes)
* if you want to patch the airline theme before it gets applied, you can
supply the name of a function where you can modify the palette. >
let g:airline_theme_patch_func = 'AirlineThemePatch'
function! AirlineThemePatch(palette)
if g:airline_theme == 'badwolf'
for colors in values(a:palette.inactive)
let colors[3] = 245
endfor
endif
endfunction
<
* if you want to update your highlights without affecting the airline theme,
you can do so using the AirlineAfterTheme autocmd. >
function! s:update_highlights()
hi CursorLine ctermbg=none guibg=NONE
hi VertSplit ctermbg=none guibg=NONE
endfunction
autocmd User AirlineAfterTheme call s:update_highlights()
<
* By default, airline will use unicode symbols if your encoding matches
utf-8. If you want the powerline symbols set this variable: >
let g:airline_powerline_fonts = 1
<
If you want to use plain ascii symbols, set this variable: >
let g:airline_symbols_ascii = 1
<
* define the set of text to display for each mode. >
let g:airline_mode_map = {} " see source for the defaults
" or copy paste the following into your vimrc for shortform text
let g:airline_mode_map = {
\ '__' : '-',
\ 'c' : 'C',
\ 'i' : 'I',
\ 'ic' : 'I',
\ 'ix' : 'I',

\ '' : 'S',
\ 't' : 'T',
\ 'v' : 'V',
\ 'V' : 'V',
\ '' : 'V',

<
* disable the Airline statusline customization for selected windows (this is a
window-local variable so you can disable it per-window) >
let w:airline_disable_statusline = 1
<
Old deprecated name: `w:airline_disabled`
See also the following options, for disabling setting the statusline
globally or per-buffer
* Disable setting the statusline option: >
" disable globally
let g:airline_disable_statusline = 1
" disable per-buffer
let b:airline_disable_statusline = 1
< This setting disables setting the 'statusline' option. This allows to use
e.g. the tabline extension (|airline-tabline|) but keep the 'statusline'
option totally configurable by a custom configuration.
* Do not draw separators for empty sections (only for the active window) >
let g:airline_skip_empty_sections = 1
<
This variable can be overridden by setting a window-local variable with
the same name (in the correct window): >
let w:airline_skip_empty_sections = 0
<
* Caches the changes to the highlighting groups, should therefore be faster.
Set this to one, if you experience a sluggish Vim: >
let g:airline_highlighting_cache = 0
<
* disable airline on FocusLost autocommand (e.g. when Vim loses focus): >
let g:airline_focuslost_inactive = 0
<
* configure the fileformat output
By default, it will display something like 'utf-8[unix]', however, you can
skip displaying it, if the output matches a configured string. To do so,
set: >
let g:airline#parts#ffenc#skip_expected_string='utf-8[unix]'
<
* Display the statusline in the tabline (first top line): >
let g:airline_statusline_ontop = 1
<
Setting this option, allows to use the statusline option to be used by
a custom function or another plugin, since airline won't change it.
Note: This setting is experimental and works on a best effort approach.
Updating the statusline might not always happen as fast as needed, but that
is a limitation, that comes from Vim. airline tries to force an update if
needed, but it might not always work as expected.
To force updating the tabline on mode changes, call `airline#check_mode()`
in your custom statusline setting: `:set stl=%!airline#check_mode(winnr())`
will correctly update the tabline on mode changes.
* Display a short path in statusline: >
let g:airline_stl_path_style = 'short'
>
* Display a only file name in statusline: >
let g:airline_section_c_only_filename = 1
>
=============================================================================
COMMANDS *airline-commands*
:AirlineTheme {theme-name} *:AirlineTheme*
Displays or changes the current theme.
Note: `random` will switch to a random theme.
:AirlineToggleWhitespace *:AirlineToggleWhitespace*
Toggles whitespace detection.
:AirlineToggle *:AirlineToggle*
Toggles between the standard 'statusline' and airline.
:AirlineRefresh[!] *:AirlineRefresh*
Refreshes all highlight groups and redraws the statusline. With the '!'
attribute, skips refreshing the highlighting groups.
:AirlineExtensions *:AirlineExtensions*
Shows the status of all available airline extensions.
Extern means, the extensions does not come bundled with Airline.
=============================================================================
AUTOCOMMANDS *airline-autocommands*
Airline comes with some user-defined autocommands.
|AirlineAfterInit| after plugin is initialized, but before the statusline
is replaced
|AirlineAfterTheme| after theme of the statusline has been changed
|AirlineToggledOn| after airline is activated and replaced the statusline
|AirlineToggledOff| after airline is deactivated and the statusline is
restored to the original
|AirlineModeChanged| The mode in Vim changed.
=============================================================================
CUSTOMIZATION *airline-customization*
The following are some unicode symbols for customizing the left/right
separators, as well as the powerline font glyphs.
Note: Some additional characters like spaces and colons may be included in the
default. Including them within the symbol definitions rather than outside of
them allows you to eliminate or otherwise alter them.
Note: Be aware that some of these glyphs are defined as ligatures, so they may
show up different (usually bigger) if followed by a space. This only happens
if both the font and terminal implementation used support ligatures. If you
want to follow a glyph with a space _without_ the alternate ligature being
rendered, follow it with a non-breaking-space character.
Note: You must define the dictionary first before setting values. Also, it's
a good idea to check whether it exists as to avoid accidentally overwriting
its contents. >
if !exists('g:airline_symbols')
let g:airline_symbols = {}
endif

<
For more intricate customizations, you can replace the predefined sections
with the usual statusline syntax.
Note: If you define any section variables it will replace the default values
entirely. If you want to disable only certain parts of a section you can
try using variables defined in the |airline-configuration| or
|airline-extensions| section.
|airline-default-sections|
The following table describes what sections are available by default, and
which extensions/functions make use of it. Note: using `g:` (global) variable
prefix means, those variables are defined for all windows. You can use `w:`
(window local variables) instead to make this apply only to a particular
window.
>
variable names default contents
---------------------------------------------------------------------------
let g:airline_section_a (mode, crypt, paste, spell, iminsert)
let g:airline_section_b (hunks, branch)[*]
let g:airline_section_c (bufferline or filename, readonly)
let g:airline_section_gutter (csv)
let g:airline_section_x (tagbar, filetype, virtualenv)
let g:airline_section_y (fileencoding, fileformat, 'bom', 'eol')
let g:airline_section_z (percentage, line number, column number)
let g:airline_section_error (ycm_error_count, syntastic-err, eclim,
languageclient_error_count)
let g:airline_section_warning (ycm_warning_count, syntastic-warn,
languageclient_warning_count, whitespace)
" [*] This section needs at least the fugitive extension or else
" it will remain empty
"
" here is an example of how you could replace the branch indicator with
" the current working directory (limited to 10 characters),
" followed by the filename.
let g:airline_section_b = '%-0.10{getcwd()}'
let g:airline_section_c = '%t'
<
*airline#ignore_bufadd_pat*
Determines a pattern to ignore a buffer name for various things (e.g. the
tabline extension) or the read-only check. Default is
`g:airline#extensions#tabline#ignore_bufadd_pat` (see below) or
`'!|defx|gundo|nerd_tree|startify|tagbar|term://|undotree|vimfiler'`
if it is unset.
The "!" prevents terminal buffers to appear in the tabline.
*airline#extensions#tabline#exclude_buffers*
Buffer numbers to be excluded from showing in the tabline (similar to
|airline#ignore_bufadd_pat|).
=============================================================================
EXTENSIONS *airline-extensions*
Most extensions are enabled by default and lazily loaded when the
corresponding plugin (if any) is detected.
By default, airline will attempt to load any extension it can find in the
'runtimepath'. On some systems this can result in an undesirable startup
cost. You can disable the check with the following flag. >
let g:airline#extensions#disable_rtp_load = 1
<
Note: Third party plugins that rely on this behavior will be affected. You
will need to manually load them.
Alternatively, if you want a minimalistic setup and would rather opt-in which
extensions get loaded instead of disabling each individually, you can declare
the following list variable: >
" an empty list disables all extensions
let g:airline_extensions = []
" or only load what you want
let g:airline_extensions = ['branch', 'tabline']
<
In addition, each extension can be configured individually. Following are
the options for each extension (in alphabetical order, after the default
extension)
Usually, each extension will only be loaded if the required Vim plugin is
installed as well, otherwise it will remain disabled. See the output of the
|:AirlineExtensions| command.

vim-airline will display the branch-indicator together with the branch name
in the statusline, if one of the following plugins is installed:

lawrencium <https://bitbucket.org/ludovicchabant/vim-lawrencium>

If a file is edited, that is not yet in the repository, the
notexists symbol will be displayed after the branch name. If the repository
is not clean, the dirty symbol will be displayed after the branch name.
* notexists symbol means you are editing a file, that has not been
committed yet
default: '?'
* the dirty symbol basically means your working directory is dirty
default: '!'
Note: the branch extension will be disabled for windows smaller than 80

By default, vim-airline will check if the current edited file is untracked
in the repository. If so, it will append the `g:airline_symbols.notexists`
symbol to the branch name.
In addition, it will check if the repository is clean, else it will append
the `g:airline_symbols.dirty` symbol to the branch name (if the current
file is not untracked). Configure, by setting the following variable: >

all other extensions, takes care of how all sections will be combined into a
'statusline' specific item and when to truncate each section.

autoload/airline/extensions/tabline/formatter/ (without .vim extension)
and needs to provide a format() function. Alternatively you can use a
custom function name, that is defined e.g. in your .vimrc file. In any
case, the function needs to take 2 arguments, tab_nr_type and tabpage
number.
For an example, have a look at the default tabline/formatter/tabnr.vim

`buffer_idx_mode` allows 3 different modes to access buffers from the
tabline. When enabled, numbers will be displayed in the tabline and
mappings will be exposed to allow you to select a buffer directly.
In default mode, when the variable is 1 Up to 10 mappings will be
exposed. Note: As 10 and 1 have same prefix, we use 0 to replace 10. So,
<leader>0 will jump to tenth buffer. Those mappings are not automatically
created, vim-airline just exposes those `<Plug>AirlineSeelctTab` keys
for you to map to a convenient key >
let g:airline#extensions#tabline#buffer_idx_mode = 1
nmap <leader>1 <Plug>AirlineSelectTab1
nmap <leader>2 <Plug>AirlineSelectTab2
nmap <leader>3 <Plug>AirlineSelectTab3
nmap <leader>4 <Plug>AirlineSelectTab4
nmap <leader>5 <Plug>AirlineSelectTab5
nmap <leader>6 <Plug>AirlineSelectTab6
nmap <leader>7 <Plug>AirlineSelectTab7
nmap <leader>8 <Plug>AirlineSelectTab8
nmap <leader>9 <Plug>AirlineSelectTab9
nmap <leader>0 <Plug>AirlineSelectTab0
nmap <leader>- <Plug>AirlineSelectPrevTab
nmap <leader>+ <Plug>AirlineSelectNextTab
<
In mode 2, (when the variable is 2) 89 mappings will be exposed: >
let g:airline#extensions#tabline#buffer_idx_mode = 2
nmap <Leader>10 <Plug>AirlineSelectTab10
nmap <Leader>11 <Plug>AirlineSelectTab11
nmap <Leader>12 <Plug>AirlineSelectTab12
nmap <Leader>13 <Plug>AirlineSelectTab13
...
nmap <Leader>99 <Plug>AirlineSelectTab99
<
The <Plug>AirlineSelect<Prev/Next>Tab mapping handles counts as well,
so one can handle arbirtrarily number of buffers/tabs.
Mode 3 is exactly the same as mode 2, except the indexing start at 01,
exposing 99 mappings: >
let g:airline#extensions#tabline#buffer_idx_mode = 3
nmap <Leader>01 <Plug>AirlineSelectTab01
nmap <Leader>02 <Plug>AirlineSelectTab02
nmap <Leader>03 <Plug>AirlineSelectTab03
...
nmap <Leader>99 <Plug>AirlineSelectTab99
<
This matches that of the numbering scheme of |:buffers|, letting
`<Plug>AirlineSelectTab67` to reference buffer 67.
Note: To avoid ambiguity, there won't be <Plug>AirlineSelectTab1
- <Plug>AirlineSelectTab9 maps in mode 2 and 3.
Note: Mappings will be ignored for filetypes that match
`g:airline#extensions#tabline#keymap_ignored_filetypes`.
Note: In buffer_idx_mode these mappings won't change the
current tab, but switch to the buffer `visible` in the current tab.
If you want to switch to a buffer, that is not visible use the
`AirlineSelectPrev/NextTab` mapping (it supports using a count).
Use |gt| for switching tabs.
In tabmode, those mappings will be exposed as well and will switch
to the specified tab.

------------------------------------- *airline-xtabline*
xtabline <https://github.com/mg979/vim-xtabline>
This is a simplified and stand-alone version of the original extension.
The bigger version adds fzf commands, session management, tab bookmarks, and
features that you may not need. They both require |vim-airline| anyway.
Main features and default mappings of this extension are:
* tab cwd persistence, also across sessions if vim-obsession is being used.
* buffer filtering in the tabline: only buffers whose path is within the tab
cwd will be shown in the tabline.
* toggle tabs/buffer view on the tabline, toggle buffer filtering:
>
nmap <F5> <Plug>XTablineToggleTabs
nmap <leader><F5> <Plug>XTablineToggleFiltering
* reopen last closed tab, restoring its cwd and buffers:
>
nmap <leader>tr <Plug>XTablineReopen <SID>ReopenLastTab
* switch among filtered buffers (accepts count):
>
nmap ]l <Plug>XTablineNextBuffer
nmap [l <Plug>XTablinePrevBuffer
* go to N buffer (a count must be provided):
>
nmap <BS> <Plug>XTablineSelectBuffer
* alternative command if count is not provided:
>
let g:xtabline_alt_action = "buffer #"
Note: Make sure to also enable >
:let g:airline#extensions#tabline#show_buffers = 1
otherwise the tabline might not actually be displayed correctly (see
|airline-tabline|)
* exclude fugitive logs and files that share part of the real buffer path:
>
let g:xtabline_include_previews = 0 (default 1)
* activate fast cwd selection mappings:
>
let g:xtabline_cd_commands = 1 (default 0)
* default mappings for them are:
>
map <leader>cdc <Plug>XTablineCdCurrent
map <leader>cdd <Plug>XTablineCdDown1
map <leader>cd2 <Plug>XTablineCdDown2
map <leader>cd3 <Plug>XTablineCdDown3
map <leader>cdh <Plug>XTablineCdHome
Note: if you don't use these mappings and change the cwd, the tabline won't
be updated automatically. Either re-enter the tab or press <F5> two times.
* here are some easier mappings to change tab buffer:
>
nnoremap <silent> <expr> <Right> v:count ?
\ airline#extensions#tabline#xtabline#next_buffer(v:count) : "\<Right>"
nnoremap <silent> <expr> <Left> v:count ?

default: ''
=============================================================================
ADVANCED CUSTOMIZATION *airline-advanced-customization*
The defaults will accommodate the mass majority of users with minimal
configuration. However, if you want to reposition sections or contents you
can do so with built-in helper functions, which makes it possible to create
sections in a more declarative style.
------------------------------------- *airline-parts*
A part is something that contains metadata that eventually gets rendered into
the statusline. You can define parts that contain constant strings or
functions. Defining parts is needed if you want to use features like automatic
insertion of separators or hiding based on window width.
For example, this is how you would define a part function: >
call airline#parts#define_function('foo', 'GetFooText')
<
Here is how you would define a part that is visible only if the window width
greater than a minimum width. >
call airline#parts#define_minwidth('foo', 50)
<
Parts can be configured to be visible conditionally. >
call airline#parts#define_condition('foo', 'getcwd() =~ "work_dir"')
<
Now add part "foo" to section section airline_section_y: >
let g:airline_section_y = airline#section#create_right(['ffenc','foo'])
<
Note: Part definitions are combinative; e.g. the two examples above modify
the same `foo` part.
Note: Look at the source code and tests for the full API.
------------------------------------- *airline-predefined-parts*
The following list of parts are predefined by vim-airline.
* `mode` displays the current mode
* `iminsert` displays the current insert method
* `paste` displays the paste indicator
* `crypt` displays the crypted indicator
* `spell` displays the spell indicator
* `filetype` displays the file type
* `readonly` displays the read only indicator
* `file` displays the filename and modified indicator
* `path` displays the filename (absolute path) and modifier indicator
* `linenr` displays the current line number
* `maxlinenr` displays the number of lines in the buffer
* `ffenc` displays the file format and encoding
And the following are defined for their respective extensions:
`ale_error_count` `ale_warning_count` `branch` `eclim` `hunks`
`languageclient_error_count` `languageclient_warning_count` `lsp_error_count`
`lsp_warning_count``neomake_error_count` `neomake_warning_count`
`nvimlsp_error_count` `nvimlsp_warning_count` `obsession`
`syntastic-warn` `syntastic-err` `tagbar` `whitespace` `windowswap`
`ycm_error_count` `ycm_warning_count`
------------------------------------- *airline-accents*
Accents can be defined on any part, like so: >
call airline#parts#define_accent('foo', 'red')
<
This will override the colors of that part by using what is defined in that
particular accent. In the above example, the `red` accent is used, which
means regardless of which section the part is used in, it will have red
foreground colors instead of the section's default foreground color.
The following accents are defined by default. Themes can define their
variants of the colors, but defaults will be provided if missing. >
bold, italic, red, green, blue, yellow, orange, purple, none
<
The defaults configure the mode and line number parts to be bold, and the
readonly part to be red.
"none" is special. This can be used, to remove a bold accent from an existing
theme. For example, the mode part of the statusline is usually defined to be
bold. However, it can be hard to remove an existing bold accent from the
default configuration. Therefore, you can use the none accent to remove
existing accents, so if you put >
call airline#parts#define_accent('mode', 'none')
the mode section will be set to non-bold font style.
------------------------------------- *airline-sections*
Once a part is defined, you can use helper functions to generate the
statuslines for each section. For example, to use the part above, we could
define a section like this: >
function! AirlineInit()
let g:airline_section_a = airline#section#create(['mode', ' ', 'foo'])
let g:airline_section_b = airline#section#create_left(['ffenc','file'])
let g:airline_section_c = airline#section#create(['%{getcwd()}'])
endfunction
autocmd User AirlineAfterInit call AirlineInit()
<
This will create a section with the `mode`, followed by a space, and our
`foo` part in section `a`. Section `b` will have two parts with a left-side
separator. And section `c` will contain the current path. You may notice that
the space and cwd are not defined parts. For convenience, if a part of that
key does not exist, it will be inserted as is. The unit tests will be a good
resource for possibilities.
Note: The use of |User| is important, because most extensions are lazily
loaded, so we must give them a chance to define their parts before we can use
them. Also this autocommand is only triggered, after the airline functions
are actually available on startup.
Note: The `airline#section#create` function and friends will do its best to
create a section with the appropriate separators, but it only works for
function and text parts. Special 'statusline' items like %f or raw/undefined
parts will not work as it is not possible to inspect their widths/contents
before rendering to the statusline.
=============================================================================
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. This is
the most powerful way to customize the statusline, and sometimes it may be
easier to go this route than the above methods.
Every section can have two values. The default value is the global `g:`
variable which is used in the absence of a `w:` value. This makes it very
easy to override only certain parts of the statusline by only defining
window-local variables for a subset of all sections.
------------------------------------- *add_statusline_func*
*add_inactive_statusline_func*
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 airline#add_statusline_func('MyPlugin')
<
Notice that only the left side of the statusline is overwritten. This means
the right side (the line/column numbers, etc) will be intact.
To have the function act only on statuslines of inactive functions, use
`airline#add_inactive_statusline_func('MyPlugin')`
------------------------------------- *remove_statusline_func*
You can also remove a function as well, which is useful for when you want a
temporary override. >
call airline#remove_statusline_func('MyPlugin')
<
=============================================================================
PIPELINE *airline-pipeline*
Sometimes you want to do more than just use overrides. The statusline funcref
is invoked and passed two arguments. The first of these arguments is the
statusline builder. You can use this to build completely custom statuslines
to your liking. Here is an example: >
>
function! MyPlugin(...)
" first variable is the statusline builder
let builder = a:1
" WARNING: the API for the builder is not finalized and may change
call builder.add_section('Normal', '%f')
call builder.add_section('WarningMsg', '%{getcwd()}')
call builder.split()
call builder.add_section('airline_z', '%p%%')
" tell the core to use the contents of the builder
return 1
endfunction
<
The above example uses various example highlight groups to demonstrate
that you can use any combination from the loaded colorscheme. However, if
you want colors to change between modes, you should use one of the section
highlight groups, e.g. `airline_a` and `airline_b`.
The second variable is the context, which is a dictionary containing various
values such as whether the statusline is active or not, and the window
number.
>
context = {
'winnr': 'the window number for the statusline',
'active': 'whether the window is active or not',
'bufnr': 'the current buffer for this window',
}
<
------------------------------------- *airline-pipeline-return-codes*
The pipeline accepts various return codes and can be used to determine the
next action. The following are the supported codes: >
0 the default, continue on with the next funcref
-1 do not modify the statusline
1 modify the statusline with the current contents of the builder
<
Note: Any value other than 0 will halt the pipeline and prevent the next
funcref from executing.
=============================================================================
WRITING EXTENSIONS *airline-writing-extensions*
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. Also, a check to
`airline#extensions#foo_plugin#enabled` should be performed to allow
the user to disable it.
b. Configuration variables for the extension should reside in the
extension, e.g. `g:airline#extensions#foo_plugin#bar_variable`.
See the source of |example.vim| for documented code of how to write one.
Looking at the other extensions is also a good resource.
=============================================================================
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.
For other examples, you can visit the official themes repository at
<https://github.com/vim-airline/vim-airline-themes>. It also includes
examples such as |jellybeans.vim| which define colors by extracting highlight
groups from the underlying colorscheme.
=============================================================================
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
<
Also if you enable true color mode in your terminal, make sure it will work
correctly with your terminal. Check if it makes a difference without it: >
set notermguicolors
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.
Q. Themes are missing
A. Themes have been extracted into the vim-airlines-themes repository. Simply
clone https://github.com/vim-airline/vim-airline-themes and everything
should work again.
Q. Performance is bad
A. Check the question at the wiki:
https://github.com/vim-airline/vim-airline/wiki/FAQ#i-have-a-performance-problem
Solutions to other common problems can be found in the Wiki:
