Please read CONTRIBUTING.md before opening a PR. You can also help with documentation in the wiki.

Screenshots

Here is a preview of what 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 for lualine.

Example :

Performance compared to other plugins

Unlike other statusline plugins, lualine loads only the components you specify, and nothing else.

Startup time performance measured with an amazing plugin dstein64/vim-startuptime

Times are measured with a 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 the average of 20 runs.

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 its components e.g. Vim's current mode.

Configuring lualine in init.vim

All the examples below are in lua. You can use the same examples in .vim files by wrapping them in lua heredoc like this:

lua << END
require('lualine').setup()
END

For more information, check out :help lua-heredoc.

Default configuration

require('lualine').setup {
  options = {
    icons_enabled = true,
    theme = 'auto',
    component_separators = { left = '', right = ''},
    section_separators = { left = '', right = ''},
    disabled_filetypes = {
      statusline = {},
      winbar = {},
    },
    ignore_focus = {},
    always_divide_middle = true,
    globalstatus = false,
    refresh = {
      statusline = 1000,
      tabline = 1000,
      winbar = 1000,
    }
  },
  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 = {},
  winbar = {},
  inactive_winbar = {},
  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 us, 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'

require('lualine').setup {
  options = { theme  = custom_gruvbox },
  ...
}

Theme structure is available here.

Separators

lualine defines two kinds of separators:

section_separators - separators between sections
component_separators - separators between the different components in sections

Note: if viewing this README in a browser, chances are the characters below will not be visible.

options = {
  section_separators = { left = '', right = '' },
  component_separators = { left = '', right = '' }
}

Here, left refers to the left-most sections (a, b, c), and right refers to the right-most 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 preferred 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)
windows (shows currently available windows)

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 function 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.
      statusline = {},       -- only ignores the ft for statusline.
      winbar = {},           -- only ignores the ft for winbar.
  },

  ignore_focus = {},         -- If current filetype is in this list it'll
                             -- always be drawn as inactive statusline
                             -- and the last window will be drawn as active statusline.
                             -- for example if you don't want statusline of
                             -- your file tree / sidebar window to have active
                             -- statusline you can add their filetypes here.

  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.

  globalstatus = false,        -- enable global statusline (have a single statusline
                               -- at bottom of neovim instead of one for  every window).
                               -- This feature is only available in neovim 0.7 and higher.

  refresh = {                  -- sets how often lualine should refreash it's contents (in ms)
    statusline = 1000,         -- The refresh option sets minimum time that lualine tries
    tabline = 1000,            -- to maintain between refresh. It's not guarantied if situation
    winbar = 1000              -- arises that lualine needs to refresh itself before this time
                               -- it'll do it.

                               -- Also you can force lualine's refresh by calling refresh function
                               -- like require('lualine').refresh()
  }
}

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.
      -- Defines the icon to be displayed in front of the component.
      -- Can be string|table
      -- As table it must contain the icon as first entry and can use
      -- color option to custom color the icon. Example:
      -- {'branch', icon = ''} / {'branch', icon = {'', color={fg='green'}}}

      -- icon position can also be set to the right side from table. Example:
      -- {'branch', icon = {'', align='right', color={fg='green'}}}
      icon = nil,

      separator = nil,      -- Determines what separator to use for the component.
                            -- Note:
                            --  When a string is provided it's treated as component_separator.
                            --  When a table is provided it's treated as section_separator.
                            --  Passing an empty string disables the separator.
                            --
                            -- These options can be used to set colored separators
                            -- around a component.
                            --
                            -- The options need to be set as such:
                            --   separator = { left = '', right = ''}
                            --
                            -- Where left will be placed on left side of component,
                            -- and right will be placed on its right.
                            --

      cond = nil,           -- Condition function, the component is loaded when the function returns `true`.

      -- Defines a custom color for the component:
      --
      -- 'highlight_group_name' | { fg = '#rrggbb'|cterm_value(0-255)|'color_name(red)', bg= '#rrggbb', gui='style' } | function
      -- Note:
      --  '|' is synonymous with 'or', meaning a different acceptable format for that placeholder.
      -- color function has to return one of other color types ('highlight_group_name' | { fg = '#rrggbb'|cterm_value(0-255)|'color_name(red)', bg= '#rrggbb', gui='style' })
      -- color functions can be used to have different colors based on state as shown below.
      --
      -- Examples:
      --   color = { fg = '#ffaa88', bg = 'grey', gui='italic,bold' },
      --   color = { fg = 204 }   -- When fg/bg are omitted, they default to the your theme's fg/bg.
      --   color = 'WarningMsg'   -- Highlight groups can also be used.
      --   color = function(section)
      --      return { fg = vim.bo.modified and '#aa3355' or '#33aa88' }
      --   end,
      color = nil, -- The default is your theme's color for that section and mode.

      -- Specify what type a component is, if 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)
      --
      -- Note:
      -- lua_expr is short for lua-expression and vim_fun is short for 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.
      on_click = nil, -- takes a function that is called when component is clicked with mouse.
                   -- the function receives several arguments
                   -- - number of clicks incase of multiple clicks
                   -- - mouse button used (l(left)/r(right)/m(middle)/...)
                   -- - modifiers pressed (s(shift)/c(ctrl)/a(alt)/m(meta)...)
    }
  }
}

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.
      hide_filename_extension =
