PERFORMANCE COMPARISM	 			 *lualine-performance_comparism*

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

Startup time performance measured with an amazing plugin
tweekmonster/startuptime.vim (https://github.com/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                                              *lualine-installation*

VIM-PLUG					 	      *lualine-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			                           *lualine-packer.nvim*
>
    use {
      'hoob3rt/lualine.nvim',
      requires = {'kyazdani42/nvim-web-devicons', opt = true}

--------------------------------------------------------------------------------
USAGE AND CUSTOMIZATION                        *lualine-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                                      *lualine-starting_lualine*
>
    local lualine = require('lualine')
    lualine.status()

SETTING A THEME                                        *lualine-setting_a_theme*
>
    lualine.theme = 'gruvbox'
<

All available themes are listed in THEMES.md (./THEMES.md)

Please create a pr if you managed to port a popular theme before me, here is
how to do it (./CONTRIBUTING.md).

CHANGING SEPARATOR IN SECTION			    *lualine-changing_separator*

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-changing_components*


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

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-loading_plugin_extensions*

Lualine extensions change statusline appearance for a window/buffer with
a plugin loaded e.g. junegunn/fzf.vim (https://github.com/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 (./EXTENSIONS.md)
