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

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

Starting lualine

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

Setting a theme

lualine.theme = 'gruvbox'
Available themes
  • gruvbox

Please create a pr if you managed to port a popular theme before me

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_diagnostics = {  }
}

lualine.inactiveSections = {
  lualine_a = {  },
  lualine_b = {  },
  lualine_c = { 'filename' },
  lualine_x = { 'location' },
  lualine_y = {  },
  lualine_z = {   }
}
Available components
  • branch
  • encoding
  • fileformat
  • filename
  • filetype
  • location
  • mode
  • progress
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' }
Available extensions
  • fzf

Please create a pr if you managed to create an extension before me

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_diagnostics = {  }
      }
      lualine.inactiveSections = {
        lualine_a = {  },
        lualine_b = {  },
        lualine_c = { 'filename' },
        lualine_x = { 'location' },
        lualine_y = {  },
        lualine_z = {   }
      }
      lualine.extensions = { 'fzf' }
      lualine.status()
    end
  }

Defining custom themes

Theme example

To create a custom theme you need to define a colorscheme for each of vim's modes. Each mode has a fg and bg field for every lualine section. This is really easy in lua. Here is and example of a gruvbox theme.

local gruvbox = {  }

local colors = {
  black = "#282828",
  white = '#ebdbb2',
  red = '#fb4934',
  green = '#b8bb26',
  blue = '#83a598',
  yellow = '#fe8019',

  gray = '#a89984',
  darkgray = '#3c3836',

  lightgray = '#504945',
  inactivegray = '#7c6f64',
}

gruvbox.normal = {
  a = {
    bg = colors.gray,
    fg = colors.black,
  },
  b = {
    bg = colors.lightgray,
    fg  = colors.white,
  },
  c = {
    bg = colors.darkgray,
    fg = colors.gray
  }
}

gruvbox.insert = {
  a = {
    bg = colors.blue,
    fg = colors.black,
  },
  b = {
    bg = colors.lightgray,
    fg = colors.white,
  },
  c = {
    bg = colors.lightgray,
    fg = colors.white
  }
}


gruvbox.visual = {
  a = {
    bg = colors.yellow,
    fg = colors.black,
  },
  b = {
    bg = colors.lightgray,
    fg = colors.white,
  },
  c = {
    bg = colors.inactivegray,
    fg = colors.black
  },
}

gruvbox.replace = {
  a = {
    bg = colors.red,
    fg = colors.black,
  },
  b = {
    bg = colors.lightgray,
    fg = colors.white,
  },
  c = {
    bg = colors.black,
    fg = colors.white
  },
}

gruvbox.command = {
  a = {
    bg = colors.green,
    fg = colors.black,
  },
  b = {
    bg = colors.lightgray,
    fg = colors.white,
  },
  c = {
    bg = colors.inactivegray,
    fg = colors.black
  },
}

gruvbox.terminal = gruvbox.normal

gruvbox.inactive = {
  a = {
    bg = colors.darkgray,
    fg = colors.gray,
  },
  b = {
    bg = colors.darkgray,
    fg = colors.gray,
  },
  c = {
    bg = colors.darkgray,
    fg = colors.gray
  },
}

lualine.theme = gruvbox
