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 :

• evil_lualine

• bubbles

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 controle just vim-startuptime andvim-plug is installed. And mesured time is complete startuptime of vim not time spent on specific plugin.

Installation

vim-plug

Plug 'hoob3rt/lualine.nvim'
" If you want to have icons in your statusline choose one of these
Plug 'kyazdani42/nvim-web-devicons'

packer.nvim

use {
  'hoob3rt/lualine.nvim',
  requires = {'kyazdani42/nvim-web-devicons', opt = true}
}

You'll also have 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.

Default config

require'lualine'.setup {
  options = {
    icons_enabled = true,
    theme = 'auto',
    component_separators = { left = '', right = ''},
    section_separators = { left = '', right = ''},
    disabled_filetypes = {}
  },
  sections = {
    lualine_a = {'mode'},
    lualine_b = {'branch', 'diff',
                  {'diagnostics', sources={'nvim_lsp', 'coc'}}},
    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 sections
• components_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)
• diagnostics (diagnostics count from your prefered source)
• 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)
• diff (git diff status)

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

options = {
  icons_enabled = true, -- displays icons in alongside component
  padding = 1, -- adds padding to the left and right of components
               -- padding can be specified to left or right separately like
               -- padding = { left = left_padding, right = right_padding }
  fmt = nil -- fmt function, formats component's output
}

Local options

sections = {
  lualine_a = {
    {
      'mode',
      icon = nil,      -- displays icon in front of the component
      separator = nil, -- Determines what separator to use for the component.
                       -- when a string is given it's treated as component_separator.
                       -- When a table is given it's treated as section_separator.
                       -- This options can be used to set colored separators
                       -- arround component. Option need to be set like
                       -- `separator = { left = '', right = ''}`.
                       -- Where left will be placed in left side of component
                       -- and right will be placed in right side of component
                       -- Passing empty string disables that separator
      cond = nil, -- condition function, component is loaded when function returns true
      -- custom color for component in format
      -- color = {fg = '#rrggbb', bg= '#rrggbb', gui='style'}
      -- or highlight group
      -- color = "WarningMsg"
      color = nil,
      -- Type option specifies what type a component is.
      -- When type is omitted lualine will guess it.
      -- Available types [format: type_name(example)]
      -- mod(branch/filename), stl(%f/%m), var(g:coc_status/bo:modifiable),
      -- luae(lua expressions), vimf(viml function name)
      -- luae is short for lua-expression and vimf is short fror vim-function
      type = nil,
    }
  }
}

Component specific local options

diagnostics component options

sections = {
  lualine_a = {
    {
      'diagnostics',
      -- table of diagnostic sources, available sources:
      -- 'nvim_lsp', 'nvim', '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 = {},
      -- displays diagnostics from defined severity
      sections = {'error', 'warn', 'info', 'hint'},
      -- all colors are in format #rrggbb
      diagnostics_color = {
        error = nil, -- changes diagnostic's error foreground color
        warn = nil,  -- changes diagnostic's warn foreground color
        info = nil,  -- Changes diagnostic's info foreground color
        hint = nil,  -- Changes diagnostic's hint foreground color
      }
      symbols = {error = 'E', warn = 'W', info = 'I', hint = 'H'}
      update_in_insert = false, -- Update diagnostics in insert mode
    }
  }
}

filename component options

sections = {
  lualine_a = {
    {
      'filename',
      file_status = true,  -- displays file status (readonly status, modified status)
      path = 0,            -- 0 = just filename, 1 = relative path, 2 = absolute path
      shorting_target = 40 -- Shortens path to leave 40 space in the window
                           -- for other components. Terrible name any suggestions?
    }
  }
}

filetype component options

sections = {
  lualine_a = {
    {
      'filetype',
      colored = true, -- displays filetype icon in color if set to `true
      icon_only = false -- Display only icon for filetype
    }
  }
}

diff component options

sections = {
  lualine_a = {
    {
      'diff',
      colored = true, -- displays diff status in color if set to true
      -- all colors are in format #rrggbb
      diff_color = {
        added = nil,    -- changes diff's added foreground color
        modified = nil, -- changes diff's modified foreground color
        removed = nil,  -- changes diff's removed foreground color
      }
      symbols = {added = '+', modified = '~', removed = '-'} -- changes diff symbols
      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.
    }
  }
}

---

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 .

You can also completely move your statuline to tabline by configuring lualine.tabline and disabling lualine.sections and lualine.inactive_sections.

tabline = {
......
  },
sections = {},
inactive_sections = {},

If you're looking for bufferline or want to show tabs in tabline . There are manny awesome plugins that can do that. For example:

• nvim-bufferline
• tabline.nvim

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 extension are loaded to improve performance. You can load extensions with:

extensions = {'quickfix'}

Available extensions

• chadtree
• fugitive
• fzf
• nerdtree
• nvim-tree
• quickfix
• toggleterm

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'}}
