Screenshots
Here is a preview of how lualine can look like.
Screenshots of all available themes are listed in THEMES.md
For those who want to break the norms. You can create custom looks in lualine.
Example :
Performance compared to other plugins
Unlike other statusline plugins lualine loads only defined components, nothing else.
Startup time performance measured with an amazing plugin dstein64/vim-startuptime
All times are measured with clean init.vim
with only vim-startuptime
,
vim-plug
and given statusline plugin installed.
In control just vim-startuptime
andvim-plug
is installed.
And measured time is complete startuptime of vim not time spent
on specific plugin. These numbers are average of 20 runs.
control | lualine | lightline | airline |
---|---|---|---|
8.943 ms | 10.140 ms | 12.522 ms | 38.850 ms |

Installation
vim-plug
Plug 'nvim-lualine/lualine.nvim'
" If you want to have icons in your statusline choose one of these
Plug 'kyazdani42/nvim-web-devicons'
packer.nvim
use {
'nvim-lualine/lualine.nvim',
requires = {'kyazdani42/nvim-web-devicons', opt = true}
}
You'll also need to have a patched font if you want icons.
Usage and customization
Lualine has sections as shown below.
+-------------------------------------------------+
| A | B | C X | Y | Z |
+-------------------------------------------------+
Each sections holds it's components e.g. current vim's mode.
Configuring lualine in init.vim
All the examples below are in lua. You can use the same examples
in .vim
file by wrapping them in lua heredoc like this:
lua << END
require'lualine'.setup()
END
checkout :help lua-heredoc
.
Default config
require'lualine'.setup {
options = {
icons_enabled = true,
theme = 'auto',
component_separators = { left = '', right = ''},
section_separators = { left = '', right = ''},
disabled_filetypes = {},
always_divide_middle = true,
},
sections = {
lualine_a = {'mode'},
lualine_b = {'branch', 'diff', 'diagnostics'},
lualine_c = {'filename'},
lualine_x = {'encoding', 'fileformat', 'filetype'},
lualine_y = {'progress'},
lualine_z = {'location'}
},
inactive_sections = {
lualine_a = {},
lualine_b = {},
lualine_c = {'filename'},
lualine_x = {'location'},
lualine_y = {},
lualine_z = {}
},
tabline = {},
extensions = {}
}
If you want to get your current lualine config. you can do so with
require'lualine'.get_config()
Starting lualine
require('lualine').setup()
Setting a theme
options = {theme = 'gruvbox'}
All available themes are listed in THEMES.md
Please create a pr if you managed to port a popular theme before me, here is how to do it.
Customizing themes
local custom_gruvbox = require'lualine.themes.gruvbox'
-- Change the background of lualine_c section for normal mode
custom_gruvbox.normal.c.bg = '#112233' -- RGB colors are supported
require'lualine'.setup{
options = { theme = custom_gruvbox },
...
}
Theme structure is available here
Separators
Lualine defines two kinds of separators:
section_separators
- separators between sectionscomponents_separators
- separators between components in sections
options = {
section_separators = { left = '', right = ''},
component_separators = { left = '', right = ''}
}
Here left means it'll be used for left sections (a, b, c) and right means it'll be used for right sections (x, y, z).
Disabling separators
options = {section_separators = '', component_separators = ''}
Changing components in lualine sections
sections = {lualine_a = {'mode'}}
Available components
branch
(git branch)buffers
(shows currently available buffers)diagnostics
(diagnostics count from your prefered source)diff
(git diff status)encoding
(file encoding)fileformat
(file format)filename
filesize
filetype
hostname
location
(location in file in line:column format)mode
(vim mode)progress
(%progress in file)tabs
(shows currently available tabs)
Custom components
Lua functions as lualine component
local function hello()
return [[hello world]]
end
sections = {lualine_a = {hello}}
Vim functions as lualine component
sections = {lualine_a = {'FugitiveHead'}}
Vim's statusline items as lualine component
sections = {lualine_c = {'%=', '%t%m', '%3p'}}
Vim variables as lualine component
Variables from g:
, v:
, t:
, w:
, b:
, o
, go:
, vo:
, to:
, wo:
, bo:
scopes can be used.
See :h lua-vim-variables
and :h lua-vim-options
if you are not sure what to use.
sections = {lualine_a = {'g:coc_status', 'bo:filetype'}}
Lua expressions as lualine component
You can use any valid lua expression as a component including
- oneliners
- global variables
- require statements
sections = {lualine_c = {"os.date('%a')", 'data', "require'lsp-status'.status()"}}
data
is a global variable in this example.
Component options
Component options can change the way a component behave. There are two kinds of options:
- global options affecting all components
- local options affecting specific
Global options can be used as local options (can be applied to specific components) but you cannot use local options as global. Global option used locally overwrites the global, for example:
require'lualine'.setup {
options = {fmt = string.lower},
sections = {lualine_a = {
{'mode', fmt = function(str) return str:sub(1,1) end}},
lualine_b = {'branch'}}
}
mode
will be formatted with the passed fa=unction so only first char will be
shown . On the other hand branch will be formatted with global formatter
string.lower
so it will be showed in lower case.
Available options
Global options
These are options
that are used in options table.
They set behavior of lualine.
Values set here are treated as default for other options that work in component level.
for example even though icons_enabled
is a general component option.
you can set icons_enabled
to false
and icons will be disabled on all
component. You can still overwrite defaults set in option table by specifying
the option value in component.
options = {
theme = 'auto', -- lualine theme
component_separators = {left = '', right = ''},
section_separators = {left = '', right = ''},
disabled_filetypes = {}, -- Filetypes to disable lualine for.
always_divide_middle = true, -- When set to true, left sections i.e. 'a','b' and 'c'
-- can't take over the entire statusline even
-- if neither of 'x', 'y' or 'z' are present.
}
General component options
These are options that control behavior at component level and are available for all components.
sections = {
lualine_a = {
{
'mode',
icons_enabled = true, -- Enables the display of icons alongside the component.
icon = nil, -- Defines the icon to be displayed in front of the component.
separator = nil, -- Determines what separator to use for the component.
-- When a string is provided it's treated as component_separator.
-- When a table is provided it's treated as section_separator.
-- These options can be used to set colored separators
-- around a component.
--
-- The options need to be set like:
-- separator = { left = '', right = ''}
--
-- Where left will be placed on left side of component,
-- and right will be placed on its right.
-- Passing an empty string disables the separator.
cond = nil, -- Condition function, the component is loaded when the function returns `true`.
-- Custom color for the component in format
-- here, '|' refers to 'or', meaning a different acceptable format for that placeholder e.g.:
-- 'highlight_group_name' | {fg = '#rrggbb'|cterm_value(0-255)|'color_name(red)', bg= '#rrggbb', gui='style'}
--
-- Note: all other color options like diff_color including themes accept same color values
--
-- example:
-- color = {fg = '#ffaa88', bg = 'grey', gui='italic,bold'},
-- color = {fg = 204} -- when fg/bg is skiped they default to themes fg/bg
-- color = 'WarningMsg' -- highlight groups can also be used
--
color = nil, -- default is themes color for that section and mode
-- This option specifies what type a component is.
-- When it's omitted lualine will guess it for you.
--
-- Available types are:
-- [format: type_name(example)], mod(branch/filename),
-- stl(%f/%m), var(g:coc_status/bo:modifiable),
-- lua_expr(lua expressions), vim_fun(viml function name)
--
-- lua_expr is short for lua-expression and vim_fun is short fror vim-function
type = nil,
padding = 1, -- Adds padding to the left and right of components.
-- Padding can be specified to left or right independently, e.g.:
-- padding = { left = left_padding, right = right_padding }
fmt = nil, -- Format function, formats the component's output.
}
}
}
Component specific options
These are options that are available on specific components.
For example you have option on diagnostics
component to
specify what your diagnostic sources will be.
buffers component options
sections = {
lualine_a = {
{
'buffers',
show_filename_only = true, -- Shows shortened relative path when set to false
show_modified_status = true, -- Shows indicator then buffer is modified
mode = 0, -- 0: Shows buffer name
-- 1: Shows buffer index (bufnr)
-- 2: Shows buffer name + buffer index (bufnr)
max_length = vim.o.columns * 2 / 3, -- Maximum width of buffers component,
-- it can also be a function that returns
-- the value of `max_length` dynamically.
filetype_names = {
TelescopePrompt = 'Telescope',
dashboard = 'Dashboard',
packer = 'Packer',
fzf = 'FZF',
alpha = 'Alpha'
}, -- Shows specific buffer name for that filetype ( { `filetype` = `buffer_name`, ... } )
buffers_color = {
-- Same values like general color option can be used here.
active = 'lualine_{section}_normal', -- Color for active buffer
inactive = 'lualine_{section}_inactive', -- Color for inactive buffer
},
}
}
}
diagnostics component options
sections = {
lualine_a = {
{
'diagnostics',
-- Table of diagnostic sources, available sources are:
-- 'nvim_lsp', 'nvim_diagnostic', 'coc', 'ale', 'vim_lsp'.
-- or a function that returns a table like:
-- {error=error_cnt, warn=warn_cnt, info=info_cnt, hint=hint_cnt}
sources = {'nvim_diagnostic', 'coc'},
-- displays diagnostics from defined severity
sections = {'error', 'warn', 'info', 'hint'},
diagnostics_color = {
-- Same values like general color option can be used here.
error = 'DiagnosticError', -- Changes diagnostics' error color
warn = 'DiagnosticWarn', -- Changes diagnostics' warn color
info = 'DiagnosticInfo', -- Changes diagnostics' info color
hint = 'DiagnosticHint', -- Changes diagnostics' hint color
},
symbols = {error = 'E', warn = 'W', info = 'I', hint = 'H'},
colored = true, -- Displays diagnostics status in color if set to true
update_in_insert = false, -- Update diagnostics in insert mode
always_visible = false, -- Show diagnostics even if there are none
}
}
}
diff component options
sections = {
lualine_a = {
{
'diff',
colored = true, -- Displays diff status in color if set to true
diff_color = {
-- Same values like general color option can be used here.
added = 'DiffAdd', -- Changes the diff's added color
modified = 'DiffChange', -- Changes the diff's modified color
removed = 'DiffDelete', -- Changes the diff's removed color you
},
symbols = {added = '+', modified = '~', removed = '-'}, -- Changes the symbols used by the diff
source = nil, -- A function that works as a data source for diff.
-- It must return a table like:
-- {added = add_count, modified = modified_count, removed = removed_count }
-- or nil on failure. count <= 0 won't be displayed.
}
}
}
fileformat component options
sections = {
lualine_a = {
{
'fileformat',
symbols = {
unix = '', -- e712
dos = '', -- e70f
mac = '', -- e711
}
}
}
}
filename component options
sections = {
lualine_a = {
{
'filename',
file_status = true, -- Displays file status (readonly status, modified status)
path = 0, -- 0: Just the filename
-- 1: Relative path
-- 2: Absolute path
shorting_target = 40, -- Shortens path to leave 40 spaces in the window
-- for other components. (terrible name, any suggestions?)
symbols = {
modified = '[+]', -- Text to show when the file is modified
readonly = '[-]', -- Text to show when the file is non-modifiable or readonly
unnamed = '[No Name]', -- Text to show for unnamed buffers
}
}
}
}
filetype component options
sections = {
lualine_a = {
{
'filetype',
colored = true, -- Displays filetype icon in color if set to true
icon_only = false -- Display only an icon for filetype
}
}
}
tabs component options
sections = {
lualine_a = {
{
'tabs',
max_length = vim.o.columns / 3, -- Maximum width of tabs component,
-- it can also be a function that returns
-- the value of `max_length` dynamically.
mode = 0, -- 0: Shows tab_nr
-- 1: Shows tab_name
-- 2: Shows tab_nr + tab_name
tabs_color = {
-- Same values like general color option can be used here.
active = 'lualine_{section}_normal', -- color for active tab
inactive = 'lualine_{section}_inactive', -- color for inactive tab
},
}
}
}
Tabline
You can use lualine to display components in tabline. The configuration for tabline sections is exactly the same as for statusline.
tabline = {
lualine_a = {},
lualine_b = {'branch'},
lualine_c = {'filename'},
lualine_x = {},
lualine_y = {},
lualine_z = {}
}
This will show branch and filename component in top of neovim inside tabline .
lualine also provides 2 components buffers & tabs that you can use to get more traditional tabline/bufferline.
tabline = {
lualine_a = {'buffers'},
lualine_b = {'branch'},
lualine_c = {'filename'},
lualine_x = {},
lualine_y = {},
lualine_z = {'tabs'}
}
You can also completely move your statusline to tabline by configuring
lualine.tabline
and disabling lualine.sections
and lualine.inactive_sections
.
tabline = {
......
},
sections = {},
inactive_sections = {},
If you want a more sophisticated tabline you can use other tabline plugins with lualine too . For example:
tabline.nvim even uses lualines theme by default 🙌 You can find a bigger list here
Extensions
Lualine extensions change statusline appearance for a window/buffer with specified filetypes.
By default no extensions are loaded to improve performance. You can load extensions with:
extensions = {'quickfix'}
Available extensions
- chadtree
- fern
- fugitive
- fzf
- nerdtree
- nvim-tree
- quickfix
- toggleterm
- symbols-outline
Custom extensions
You can define your own extensions. If you think an extension might be useful for others then please submit a pr.
local my_extension = {sections = {lualine_a = {'mode'}}, filetypes = {'lua'}}
require'lualine'.setup {extensions = {my_extension}}
Disabling lualine
You can disable lualine for specific filetypes
options = {disabled_filetypes = {'lua'}}
