Performance compared to other plugins

Unlike other statusline plugins lualine loads only defined components, nothing else.

Startup time performance measured with an amazing plugin tweekmonster/startuptime.vim

All times are measured with only startuptime.vim and given statusline plugin installed

clean vimrc	lualine	lightline	airline
8.943 ms	9.034 ms	11.463 ms	13.425 ms

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'
Plug 'ryanoasis/vim-devicons'

packer.nvim

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

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. Colorscheme of sections is mirrored, meaning section A will have the same colorscheme as section Z etc.

Configuration is currently limited to lua, please use lua block or a separate lua file to configure lualine.

Starting lualine

local lualine = require('lualine')
lualine.status()

Setting a theme

lualine.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.

Changing separator in section

Lualine defines a separator between components in given section, the default separator is |. You can change the separator this way:

lualine.separator = '|'

or disable it

lualine.separator = ''

Changing components in lualine sections

Lualine defaults

lualine.sections = {
  lualine_a = { 'mode' },
  lualine_b = { 'branch' },
  lualine_c = { 'filename' },
  lualine_x = { 'encoding', 'fileformat', 'filetype' },
  lualine_y = { 'progress' },
  lualine_z = { 'location'  },
}

lualine.inactive_sections = {
  lualine_a = {  },
  lualine_b = {  },
  lualine_c = { 'filename' },
  lualine_x = { 'location' },
  lualine_y = {  },
  lualine_z = {   }
}

Available components

• general
  • branch
  • encoding
  • fileformat
  • filename
  • filetype
  • location
  • mode
  • progress
• plugin
  • signify

Using custom functions as lualine component

You can define a custom function as a lualine component

local function hello()
  return [[hello world]]
end
lualine.sections.lualine_a = { hello }

Loading plugin extensions

Lualine extensions change statusline appearance for a window/buffer with a plugin loaded e.g. junegunn/fzf.vim

By default no plugin extension are loaded to improve performance. If you are using a plugin which is supported you can load it this way:

lualine.extensions = { 'fzf' }

All available extensions are listed in EXTENSIONS.md

Full config example using packer.nvim

packer config

  use {
    'hoob3rt/lualine.nvim',
    requires = {'kyazdani42/nvim-web-devicons', opt = true},
    config = function()
      local lualine = require('lualine')
      lualine.theme = 'gruvbox'
      lualine.separator = '|'
      lualine.sections = {
        lualine_a = { 'mode' },
        lualine_b = { 'branch' },
        lualine_c = { 'filename' },
        lualine_x = { 'encoding', 'fileformat', 'filetype' },
        lualine_y = { 'progress' },
        lualine_z = { 'location'  },
      }
      lualine.inactive_sections = {
        lualine_a = {  },
        lualine_b = {  },
        lualine_c = { 'filename' },
        lualine_x = { 'location' },
        lualine_y = {  },
        lualine_z = {   }
      }
      lualine.extensions = { 'fzf' }
      lualine.status()
    end
  }
