lualine.nvim

code size license

A blazing fast and easy to configure Neovim statusline written in Lua.

lualine.nvim requires Neovim >= 0.5.

Contributing

Feel free to create an issue/PR if you want to see anything else implemented. If you have some question or need help with configuration, start a discussion.

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.

      -- 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,

      },
    }
  }

Tabline

You can use lualine to display components in tabline. The configuration for tabline sections is exactly the same as that of the statusline.

tabline = {
  lualine_a = {},
  lualine_b = {'branch'},
  lualine_c = {'filename'},
  lualine_x = {},
  lualine_y = {},
  lualine_z = {}
}

This will show the branch and filename components on top of neovim inside tabline.

lualine also provides 2 components, buffers and tabs, that you can use to get a more traditional tabline/bufferline.

tabline = {
  lualine_a = {'buffers'},
  lualine_b = {'branch'},
  lualine_c = {'filename'},
  lualine_x = {},
  lualine_y = {},
  lualine_z = {'tabs'}
}

Winbar

From neovim-0.8 you can customize your winbar with lualine. Winbar configuration is similar to statusline.

winbar = {
  lualine_a = {},
  lualine_b = {},
  lualine_c = {'filename'},
  lualine_x = {},
  lualine_y = {},
  lualine_z = {}
}

inactive_winbar = {
  lualine_a = {},
  lualine_b = {},
  lualine_c = {'filename'},
  lualine_x = {},
  lualine_y = {},
  lualine_z = {}
}

Just like statusline you can separately specify winbar for active and inactive windows. Any lualine component can be placed in winbar. All kinds of custom components supported in statusline are also suported for winbar too. In general You can treat winbar as another lualine statusline that just appears on top of windows instead of at bottom.

Buffers

Shows currently open buffers. Like bufferline . See buffers options for all builtin behaviors of buffers component. You can use :LualineBuffersJump to jump to buffer based on index of buffer in buffers component. Jumping to non-existent buffer indices generates an error. To avoid these errors LualineBuffersJump provides <bang> support, meaning that you can call :LualineBufferJump! to ignore these errors.

  :LualineBuffersJump 2  " Jumps to 2nd buffer in buffers component.
  :LualineBuffersJump $  " Jumps to last buffer in buffers component.
  :LualineBuffersJump! 3  " Attempts to jump to 3rd buffer, if it exists.

Tabs

Shows currently open tab. Like usual tabline. See tabs options for all builtin behaviors of tabs component. You can also use :LualineRenameTab to set a name for a tabpage. For example:

:LualineRenameTab Project_K

It's useful when you're using rendering mode 2/3 in tabs. To unname a tabpage run :LualineRenameTab without argument.

Tabline as statusline

You can also completely move your statusline to a 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 lualine's 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

  • aerial
  • chadtree
  • fern
  • fugitive
  • fzf
  • man
  • mundo
  • neo-tree
  • nerdtree
  • nvim-dap-ui
  • nvim-tree
  • quickfix
  • symbols-outline
  • toggleterm

Custom extensions

You can define your own extensions. If you believe an extension may be useful to others, then please submit a PR.

local my_extension = { sections = { lualine_a = {'mode'} }, filetypes = {'lua'} }
require('lualine').setup { extensions = { my_extension } }

Refreshing lualine

By default lualine refreshes itself based on timer and some events. You can set the interval of the timer with refresh option. However you can also force lualine to refresh at any time by calling lualine.refresh function.

require('lualine').refresh({
  scope = 'tabpage',  -- scope of refresh all/tabpage/window
  place = { 'statusline', 'winbar', 'tabline' },  -- lualine segment ro refresh.
})

The arguments shown here are default values. So not passing any of them will be treated as if a default value was passed.

So you can simply do

require('lualine').refresh()

Avoid calling lualine.refresh inside components. Since components are evaluated during refresh, calling refresh while refreshing can have undesirable effects.

Disabling lualine

You can disable lualine for specific filetypes:

options = { disabled_filetypes = {'lua'} }

You can also disable lualine completely.

  require('lualine').hide({
    place = {'statusline', 'tabline', 'winbar'}, -- The segmentthis change applies to.
    unhide = false,  -- whether to reenable lualine again/
  })

The arguments show for hide above are default values. Which means even if the hide function is called without arguments it'll work as if these were passed.

So in short to disable lualine completely you can do

require('lualine').hide()

To enable it again you can do

require('lualine').hide({unhide=true})
